Abstract
Herbal spices are an agricultural commodity, economically very important and beneficial in primary healthcare in the food and medicine sectors. Herbal spices are used as food flavoring agents as well as in phytotherapies throughout the world and have nutritive benefits. The food and medicine industries widely employ artificial or natural adulteration to retard the deterioration and utilization of these adulterants in food and medicine products has given rise to significant apprehension among consumers, primarily stemming from the potential health risks that they pose. Thus, their characterization for the purpose of identification, origin, and quality assurance is mandatory for safe human consumption. Here, we studied 22 samples of commonly traded herbal spices that belong to 20 different genera and 21 species comprising 14 families, investigated macroscopically or organoleptically as well as histologically under microscopic examination. In this study, we provide details on organoleptic features including appearance, taste, odor, color, shape, size, fractures, types of trichomes, and the presence of lenticels among the examined herbal spices and these features have great significance in the detection of both natural as well as artificial deterioration. In terms of microscopic characterization, each examined plant part comprising different anatomical characteristics has taxonomic importance and also provides useful information for authentication from natural adulterants. Furthermore, the studied taxa were also described with nutritive and therapeutic properties. For condiments, herbal beverages and medicinal purposes, different herbal parts such as leaves, floral buds, seeds, fruit, and accessory parts like mericarp, rhizome, bulbs, and bark were used and commercially traded. Similarly, in this study, the leaves of Cinnamomum tamala and Mentha spicata, the floral buds of Syzygium aromaticum, the seeds of Amomum subulatum, Brassica nigra, Punica granatum, Myristica fragrans, Phyllanthus emblica, and Elettaria cardamomum, the mericarp of Coriandrum sativum, and Cuminum cyminum were observed. As a result, we show the potential of herbal spices as a source of many valuable phytochemicals and essential nutrients for food, nutraceutical, and homoeopathic medicine.

Abstract
The molecule (S)-4,5-dihydroxy-2,3-pentanedione (DPD) is produced by many different species of bacteria and is involved in bacterial communication. DPD is the precursor of signal molecule autoinducer-2 (AI-2) and has high potential to be used as a vaccine adjuvant. Vaccine adjuvants are compounds that enhance the stability and immunogenicity of vaccine antigens, modulate efficacy, and increase the immune response to a particular antigen. Previously, the microparticulate form of (S)-DPD was found to have an adjuvant effect with the gonorrhea vaccine. In this study, we evaluated the immunogenicity and adjuvanticity of several synthetic analogs of the (S)-DPD molecule, including ent-DPD((R)-4,5-dihydroxy-2,3-pentanedione), n-butyl-DPD ((S)-1,2-dihydroxy-3,4-octanedione), isobutyl-DPD ((S)-1,2-dihydroxy-6-methyl-3,4-heptanedione), n-hexyl-DPD ((S)-1,2-dihydroxy-3,4-decanedione), and phenyl-DPD ((S)-3,4-dihydroxy-1-phenyl-1,2-butanedione), in microparticulate formulations. The microparticulate formulations of all analogs of (S)-DPD were found to be noncytotoxic toward dendritic cells. Among these analogs, ent-DPD, n-butyl-DPD, and isobutyl-DPD were found to be immunogenic toward antigens and showed adjuvant efficacy with microparticulate gonorrhea vaccines. It was observed that n-hexyl-DPD and phenyl-DPD did not show any adjuvant effect. This study shows that synthetic analogs of (S)-DPD molecules are capable of eliciting adjuvant effects with vaccines. A future in vivo evaluation will further confirm that these analogs are promising vaccine adjuvants.

Abstract
Tacrolimus (TL) is a topical calcineurin inhibitor immunosuppressive drug widely used to manage various skin disorders. Herein, we report a TL-loaded microsphere gel formulation with severe atopic dermatitis effects that are required to manage skin disorders. The current study adopted a modified emulsion solvent evaporation technique to synthesize TL-loaded microspheres, which were further converted into gels for skin use. Characterization of the synthesized formulation was performed by differential dynamic light scattering, scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, X-ray crystallography, Brunauer-Emmett-Teller (BET) analysis, differential scanning calorimetry, and drug release. A Franz diffusion cell was used to study the diffusion of TL for up to 8 h at pH 6.8 and 5.5. Evaluation of cell viability was determined by MTT assay and showed higher IC50 values compared to the plain drug. RNA extraction, real-time polymerase chain reaction (RT-PCR), and reverse transcription were also performed to determine the expression levels of the anti-inflammatory cytokine IL-2. Particle size determination was performed by a zeta sizer, and the TL microsphere size was 1745 ± 70 nm with a good polydispersity (0.337 ± 0.12). The drug entrapment efficiency was also very good at 60% ± 10, and the drug release was 93.9% ± 3.5 within 8 h. An in vitro diffusion study of the formulation also showed improved permeability at both pH values (4.5 and 5.5). The findings of the hemolytic tests demonstrated that TL-MG at concentrations of 50, 100, and 200 mg/mL did not produce any hemolysis. A dose-dependent pattern of cytotoxicity was found during the cell viability assay, with an IC50 value of 787.55 ± 12.78 µg/mL. There was a significant decrease in the IL-2 level in the TL-MG group compared to the other groups. TL-MG microspheres were nontoxic carriers for tacrolimus delivery, with greater loading capacity, a significant release profile, and enhanced cellular uptake with improved permeability.

Abstract
Alpha arbutin is a skin-whitening agent in cosmetics. Structurally, it is 4-hydroxyphenyl-α-glucopyranoside. Ethosomes encourage the formation of lamellar-shaped vesicles with improved solubility and entrapment of whitening agents. The objective of this study was to fabricate an optimized nanostructured ethosomal gel loaded with alpha arbutin for the treatment of skin pigmentation. Different ethosomal suspensions of alpha arbutin were prepared by the cold method. Invitro evaluation included zeta potential, droplet size analysis, polydispersity index, entrapment efficiency (EE), scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. Stability studies of the optimized ethosomal and control gels were performed for three months under different temperature conditions. The optimized ethosomal gel loaded with alpha arbutin was further analyzed on human volunteers for skin benefits by measuring melanin level, moisture content and elasticity. It was concluded that the optimized formulation had a size, zeta potential, polydispersity index and entrapment efficiency of 196.87 nm, -45.140 mV, 0.217 and 93.458343%, respectively. Scanning electron microscopy (SEM) depicted spherical ethosomal vesicles. Stability data was obtained in terms of pH and conductivity. Rheological analysis revealed non-Newtonian flow. The cumulative drug permeated for ethosomal gel was 78.4%. Moreover, encapsulation of alpha arbutin causes significant improvement in skin melanin, moisture content and elasticity. The overall findings suggested that the arbutin-loaded ethosomal formulation was stable and could be a better approach than conventional formulation for cosmeceutical purposes such as for depigmentation and moisturizing effects.

Abstract
The aim of this study is to formulate polymeric paclitaxel nanoparticles with various stabilizers to improve solubility, enhance stability, maximize therapeutic efficacy and minimize detrimental toxicities of paclitaxel. In this study, trastuzumab-guided poly lactic-co-glycolic acid (PLGA)-loaded paclitaxel nanoparticles were formulated with pluronic F-127, polyvinyl alcohol (PVA), poloxamer 407, Tween-80, span 20, sodium dodecyl sulfate (SDS), and sodium lauryl sulfate (SLS) at different concentrations (0.5, 1, 1.5 and 2%) using the solvent evaporation method. The nanoparticles were evaluated for physicochemical characteristics and short and long-term stability. The optimum particle size (190 nm ± 12.42 to 350 nm ± 11.1), PDI (0.13 ± 0.02 to 0.2 ± 0.01), surface charge (-19.1mv ± 1.5 to -40.4mv ± 1.6), drug loading (2.43 to 9.5 %) and encapsulation efficiency (greater than 80 %) were obtained with these stabilizers while keeping the polymer concentration, temperature, probe size, amplitude and sonication time constant. The nanoformulations were stably stored at 4 °C. The nanoformulations of paclitaxel with pluronic F-127, polyvinyl alcohol (PVA), and poloxamer 407 were found to be more soluble, stable, uniform in physicochemical properties, and efficient in drug loading and encapsulation for improved therapeutic effects.

Abstract
PURPOSE The goal of this study was to make pH-sensitive HPMC/Neocel C19-based interpenetrating polymeric networks (IPNs) that could be used to treat different diseases. An assembled novel carrier system was demonstrated in this study to achieve multiple functions such as drug protection and self-regulated release. METHODS Misoprostol (MPT) was incorporated as a model drug in hydroxyl-propyl-methylcellulose (HPMC)- and Neocel C19-based IPNs for controlled release. HPMC- and Neocel C19-based IPNs were fabricated through an aqueous polymerization method by utilizing the polymers HPMC and Neocel C19, the initiator ammonium peroxodisulfate (APS), the crosslinker methylenebisacrylamide (MBA), and the monomer methacrylic acid (MAA). An IPN based on these materials was created using an aqueous polymerization technique. Samples of IPN were analyzed using scanning electron microscopy (SEM), atomic force microscopy (AFM), differential scanning calorimetry (DSC), thermal analysis (TGA), and powder X-ray diffraction (PXRD). The effects of the pH levels 1.2 and 7.4 on these polymeric networks were also studied in vitro and through swelling experiments. We also performed in vivo studies on rabbits using commercial tablets and hydrogels. RESULTS The thermal stability measured using TGA and DSC for the revised formulation was higher than that of the individual components. Crystallinity was low and amorphousness was high in the polymeric networks, as revealed using powder X-ray diffraction (PXRD). The results from the SEM analysis demonstrated that the surface of the polymeric networks is uneven and porous. Better swelling and in vitro results were achieved at a high pH (7.4), which endorses the pH-responsive characteristics of IPN. Drug release was also increased in 7.4 pH (80% in hours). The pharmacokinetic properties of the drugs showed improvement in our work with hydrogel. The tablet MRT was 13.17 h, which was decreased in the hydrogels, and its AUC was increased from 314.41 ng h/mL to 400.50 ng h/mL in hydrogels. The blood compatibility of the IPN hydrogel was measured using different weights (100 mg, 200 mg, 400 mg, and 600 mg; 5.34%, 12.51%, 20.23%, and 29.37%, respectively). CONCLUSIONS As a result, IPN composed of HPMC and Neocel C19 was successfully synthesized, and it is now possible to use it for the controlled release of MPT.

Abstract
COVID-19 continues to cause an increase in the number of cases and deaths worldwide. Due to the ever-mutating nature of the virus, frequent vaccination against COVID-19 is anticipated. Most of the approved SARS-CoV-2 vaccines are administered using the conventional intramuscular route, causing vaccine hesitancy. Thus, there is a need for an effective, non-invasive vaccination strategy against COVID-19. This study evaluated the synergistic effects of a subunit microparticulate vaccine delivered using microneedles. The microparticles encapsulated a highly immunogenic subunit protein of the SARS-CoV-2 virus, such as the spike protein's receptor binding domain (RBD). Adjuvants were also incorporated to enhance the spike RBD-specific immune response. Our vaccination study reveals that a microneedle-based vaccine delivering these microparticles induced spike RBD-specific IgM, IgG, IgG1, IgG2a, and IgA antibodies. The vaccine also generated high levels of CD4+ and CD8a+ molecules in the secondary lymphoid organs. Overall, dissolving microneedles delivery spike RBD antigen in microparticulate form induced a robust immune response, paving the way for an alternative self-administrable, non-invasive vaccination strategy against COVID-19.

Abstract
OBJECTIVES To evaluate the release profile of different modified-release oral formulations of niacin, such as immediate-release (IR) powder and tablets, timed-release (TR) caplets, extended-release (ER) capsules, and controlled-release (CR) tablets, to assure their defined release pattern and correlate this release with their matrix polymers. SIGNIFICANCE Niacin is used to manage hyperlipidemia by reducing cutaneous flushing and hepatotoxicity adverse events. The release profiles of different types of modified-release dosage forms depend on the types of coating materials (polymers) used in the matrix formation. Although different types of niacin formulations exist, none of the niacin dissolution profiles have been evaluated and compared in the literature. METHODS Four commercial orally modified-release niacin brands were collected from a local CVS pharmacy retail store, in Miami, FL, USA. The in vitro release study was conducted in simulated gastric fluid (SGF) and simulated intestinal fluid (SIF) conditions. RESULTS The results of the release patterns of four niacin-modified dosage forms (IR, ER, TR, and CR) were aligned with their release definitions. However, the CR dosage form did not follow an ideal release pattern. CONCLUSIONS The release rate of niacin in vitro was pH dependent, which was confirmed by the similarity factor (f2) results. All the f2 comparison values were below 50 in both the SIF and SGF media, while all the comparisons were below the f2 values for all brands in the SIF media.

Abstract
PURPOSE Numerous carbohydrate polymers are frequently used in wound-dressing films because they are highly effective materials for promoting successful wound healing. In this study, we prepared amikacin (AM)-containing hydrogel films through the cross-linking of chitosan (CS) with folic acid along with methacrylic acid (MA), ammonium peroxodisulfate (APS), and methylenebisacrylamide (MBA). In the current studies, an effort has been made to look at the possibilities of these materials in developing new hydrogel film wound dressings meant for a slow release of the antibiotic AM and to enhance the potential for wound healing. METHODS Free-radical polymerization was used to generate the hydrogel film, and different concentrations of the CS polymer were used. Measurements were taken of the film thickness, weight fluctuation, folding resistance, moisture content, and moisture uptake. HPLC, FTIR, SEM, DSC, and AFM analyses were some of the different techniques used to confirm that the films were successfully developed. RESULTS The AM release profile demonstrated regulated release over a period of 24 h in simulated wound media at pH 5.5 and 7.4, with a low initial burst release. The antibacterial activity against gram-negative bacterial strains exhibited substantial effectiveness, with inhibitory zones measuring approximately 20.5 ± 0.1 mm. Additionally, in vitro cytocompatibility assessments demonstrated remarkable cell viability, surpassing 80%, specifically when evaluated against human skin fibroblast (HFF-1) cells. CONCLUSIONS The exciting findings of this study indicate the promising potential for further development and testing of these hydrogel films, offering effective and controlled antibiotic release to enhance the process of wound healing.

Abstract
Percutaneous coronary intervention (PCI) is one of the most important modalities of treatment for coronary artery disease (CAD). Minor extents of injury to the myocardium have been observed even after successful PCI. This peri-procedural injury might therefore reduce some of the beneficial effects of coronary revascularization. The objective of this hospital based comparative observational study was to determine the prevalence of post procedural Cardiac troponin I (cTnI) elevation after elective PCI and also to find out the relation with risk factors such as age, sex, body mass index (BMI), smoking, anemia, diabetes mellitus, hypertension, dyslipidemia, family history, left ventricular dysfunction, renal insufficiency, type of stent, number of stent and length of stent. This was a hospital based comparative observational study carried out in the Department of Cardiology, Chattogram Medical College Hospital (CMCH), Chattogram, Bangladesh from July 2018 to June 2019. A total of 50 patients who underwent elective PCI were included as sampled by purposive sampling method. Serum cTnI was measured by FIA8000 quantitative immunoassay analyzer with an analytical measurement before and at 24 hours of PCI. Value >1.0ng/ml was considered elevated. Univariate and multivariate analysis were applied to assess predictors for the occurrence of post-procedural elevation of cTnI. The mean±SD age of the study population was 54.96±9.1 years (range 35-74 years) and 34(68.0%) patients were male. Regarding cardiovascular risk factors, 17(34.0%) patients had diabetes mellitus, 27(54.0%) had dyslipidemia, 30(60.0%) had hypertension, 32(64.0%) were current or ex-smokers and 20(40.0%) had a family history of CAD. Eighteen patients (36.0%) had post-procedural cTnI elevation but only 8(16.0%) had significant (>1.0ng/ml) elevation. Change of cTnI before and at 24 hours of PCI was not significant (p=0.057). Cardiac Troponin I increase was related to age, pre-procedural serum creatinine and multi-vessel stenting. Minor elevation of cTnI was common following elective PCI and associated with few risk factors such as elderly patient (more than 50 years), raised serum creatinine and multi-vessel stenting. So, early detection of these risk factors, as well as effective intervention may help to prevent injury to cardiac tissue hence stop elevation of cardiac TnI following elective PCI.

Abstract
This study focused on developing an influenza vaccine delivered in polymeric nanoparticles (NPs) using dissolving microneedles. We first formulated an influenza extracellular matrix protein 2 virus-like particle (M2e VLP)-loaded with poly(lactic-co-glycolic) acid (PLGA) nanoparticles, yielding M2e5x VLP PLGA NPs. The vaccine particles were characterized for their physical properties and in vitro immunogenicity. Next, the M2e5x VLP PLGA NPs, along with the adjuvant Alhydrogel® and monophosphoryl lipid A® (MPL-A®) PLGA NPs, were loaded into fast-dissolving microneedles. The vaccine microneedle patches were then evaluated in vivo in a murine model. The results from this study demonstrated that the vaccine nanoparticles effectively stimulated antigen-presenting cells in vitro resulting in enhanced autophagy, nitric oxide, and antigen presentation. In mice, the vaccine elicited M2e-specific antibodies in both serum and lung supernatants (post-challenge) and induced significant expression of CD4+ and CD8+ populations in the lymph nodes and spleens of immunized mice. Hence, this study demonstrated that polymeric particulates for antigen and adjuvant encapsulation, delivered using fast-dissolving microneedles, significantly enhanced the immunogenicity of a conserved influenza antigen.

Abstract
The midbrain periaqueductal gray (PAG), particularly its ventrolateral column (vlPAG), is part of a key descending pathway that modulates nociception, fear and anxiety behaviours in both humans and rodents. It has been previously demonstrated that inhibitory GABAergic neurons within the vlPAG have a major role in this nociceptive modulation. However, the PAG contains a diverse range of neuronal subtypes and the contribution of different subtypes of inhibitory neurons to nociceptive control has not been investigated. Here, we employed a chemogenetic strategy in mice that express Cre- under the promotor for the glycine transporter 2 (GlyT2::cre) to modulate a novel group of glycinergic neurons within the vlPAG and then investigate their role in nociceptive control. We show that activation of GlyT2-PAG neurons enhances cold and noxious heat responses and increases locomotor activity in both male and female mice. In contrast, inhibition of GlyT2-PAG neurons reduced nociceptive responses, while locomotor behaviours were unaffected. Our findings demonstrate that GlyT2+ neurons in the vlPAG modulate nociception and suggest that strategies targeting GlyT2-PAG neurons could be used to design novel analgesic therapies.Summary statementNeuronal circuits are composed of diverse collections of cell types, each with a distinct set of synaptic connections that determine their role in specific functions. One challenge in neuropharmacology is to design drugs that interact with the brain circuits required to have the desired therapeutic effect and limit their activity at nearby circuits, thus reducing side effects. The current study shows that a genetically identified subpopulation of GlyT2+ neurons that are concentrated in the vlPAG can bidirectionally modulate nociceptive responses and alter locomotion behaviours in mice. These findings provided novel insights into the organization of the nociceptive circuitry of the PAG and identify GlyT2-PAG neurons as a potential target for analgesic drug design.

Abstract
Autoinducers AI-1 and AI-2 play an important role in bacterial quorum sensing (QS), a form of chemical communication between bacteria. The autoinducer N-octanoyl-L-Homoserinehomoserine lactone (C8-HSL) serves as a major inter- and intraspecies communicator or 'signal', mainly for Gram-negative bacteria. C8-HSL is proposed to have immunogenic properties. The aim of this project is to evaluate C8-HSL as a potential vaccine adjuvant. For this purpose, a microparticulate formulation was developed. The C8-HSL microparticles (MPs) were formulated by a water/oil/water (W/O/W) double-emulsion solvent evaporation method using PLGA (poly (lactic-co-glycolic acid)) polymer. We tested C8-HSL MPs with two spray-dried bovine serum albumin (BSA)-encapsulated bacterial antigens: colonization factor antigen I (CFA/I) from Escherichia coli (E. coli.) and the inactive protective antigen (PA) from Bacillus anthracis (B. anthracis). We formulated and tested C8-HSL MP to determine its immunogenicity potential and its ability to serve as an adjuvant with particulate vaccine formulations. An in vitro immunogenicity assessment was performed using Griess's assay, which indirectly measures the nitric oxide radical (NOˑ) released by dendritic cells (DCs). The C8-HSL MP adjuvant was compared with FDA-approved adjuvants to determine its immunogenicity potential. C8-HSL MP was combined with particulate vaccines for measles, Zika and the marketed influenza vaccine. The cytotoxicity study showed that MPs were non-cytotoxic toward DCs. Griess's assay showed a comparable release of NOˑ from DCs when exposed to CFA and PA bacterial antigens. Nitric oxide radical (NOˑ) release was significantly higher when C8-HSL MPs were combined with particulate vaccines for measles and Zika. C8-HSL MPs showed immunostimulatory potential when combined with the influenza vaccine. The results showed that C8-HSL MPs were as immunogenic as FDA-approved adjuvants such as alum, MF59, and CpG. This proof-of-concept study showed that C8-HSL MP displayed adjuvant potential when combined with several particulate vaccines, indicating that C8-HSL MPs can increase the immunogenicity of both bacterial and viral vaccines.

Abstract
SARS-CoV-2, the causal agent of COVID-19, is a contagious respiratory virus that frequently mutates, giving rise to variant strains and leading to reduced vaccine efficacy against the variants. Frequent vaccination against the emerging variants may be necessary; thus, an efficient vaccination system is needed. A microneedle (MN) vaccine delivery system is non-invasive, patient-friendly, and can be self-administered. Here, we tested the immune response produced by an adjuvanted inactivated SARS-CoV-2 microparticulate vaccine administered via the transdermal route using a dissolving MN. The inactivated SARS-CoV-2 vaccine antigen and adjuvants (Alhydrogel® and AddaVax™) were encapsulated in poly(lactic-co-glycolic acid) (PLGA) polymer matrices. The resulting MP were approximately 910 nm in size, with a high percentage yield and percent encapsulation efficiency of 90.4%. In vitro, the vaccine MP was non-cytotoxic and increased the immunostimulatory activity measured as nitric oxide release from dendritic cells. The adjuvant MP potentiated the immune response of the vaccine MP in vitro. In vivo, the adjuvanted SARS-CoV-2 MP vaccine induced high levels of IgM, IgG, IgA, IgG1, and IgG2a antibodies and CD4+ and CD8+ T-cell responses in immunized mice. In conclusion, the adjuvanted inactivated SARS-CoV-2 MP vaccine delivered using MN induced a robust immune response in vaccinated mice.

Abstract
Although the global Zika epidemic in 2015–16 fueled vaccine development efforts, there is no approved Zika vaccine or treatment available to date. Current vaccine platforms in clinical trials are administered via either subcutaneous or intramuscular injections, which are painful and decrease compliance. Therefore, in the present study, we explored Zika vaccine microparticles (MPs)-loaded dissolving microneedles (MNs) with adjuvant MPs encapsulating Alhydrogel® and MPL-A® administered via the transdermal route as a pain-free vaccine strategy. We characterized the MNs for needle length, pore formation, and dissolvability when applied to murine skin. Further, we evaluated the in vivo efficacy of vaccine MPs-loaded MNs with or without adjuvants by measuring the immune response after transdermal immunization. The vaccine MPs-loaded dissolving MNs with adjuvants induced significant IgG, IgG1, and IgG2a titers in immunized mice compared to the untreated control group. After the dosing regimen, the animals were challenged with Zika virus, monitored for seven days, and sacrificed to collect spleen and lymph nodes. The lymphocytes and splenocytes from the immunized mice showed significant expressions of helper (CD4) and cytotoxic (CD8a) cell surface markers compared to the control group. Thus, this study puts forth a ‘proof-of-concept’ for a pain-free transdermal vaccine strategy against Zika.

Abstract
BACKGROUND Chronic arsenic (As) exposure is a global environmental health issue. Inorganic As (InAs) undergoes methylation to monomethyl (MMAs) and dimethyl-arsenical species (DMAs); full methylation to DMAs facilitates urinary excretion and is associated with reduced risk for As-related health outcomes. Nutritional factors, including folate and creatine, influence one-carbon metabolism, the biochemical pathway that provides methyl groups for As methylation. OBJECTIVE Our aim was to investigate the effects of supplementation with folic acid (FA), creatine, or the two combined on the concentrations of As metabolites and the primary methylation index (PMI: MMAs/InAs) and secondary methylation index (SMI: DMAs/MMAs) in blood in Bangladeshi adults having a wide range of folate status. METHODS In a randomized, double-blinded, placebo (PBO)-controlled trial, 622 participants were recruited independent of folate status and assigned to one of five treatment arms: a) PBO (n = 102 ), b) 400 μ g FA/d (400FA; n = 153 ), c) 800 μ g FA/d (800FA; n = 151 ), d) 3 g creatine/d (creatine; n = 101 ), or e) 3 g creatine + 400 μ g of FA / d (creatine + 400 FA ; n = 103 ) for 12 wk. For the following 12 wk, half of the FA participants were randomly switched to the PBO while the other half continued FA supplementation. All participants received As-removal water filters at baseline. Blood As (bAs) metabolites were measured at weeks 0, 1, 12, and 24. RESULTS At baseline, 80.3% (n = 489 ) of participants were folate sufficient (≥ 9 nmol / L in plasma). In all groups, bAs metabolite concentrations decreased, likely due to filter use; for example, in the PBO group, blood concentrations of MMAs (bMMAs) (geometric mean ± geometric standard deviation ) decreased from 3.55 ± 1.89 μ g / L at baseline to 2.73 ± 1.74 at week 1. After 1 wk, the mean within-person increase in SMI for the creatine + 400 FA group was greater than that of the PBO group (p = 0.05 ). The mean percentage decrease in bMMAs between baseline and week 12 was greater for all treatment groups compared with the PBO group [400FA: - 10.4 (95% CI: - 11.9 , - 8.75 ), 800FA: - 9.54 (95% CI: - 11.1 , - 7.97 ), creatine: - 5.85 (95% CI: - 8.59 , - 3.03 ), creatine + 400 FA : - 8.44 (95% CI: - 9.95 , - 6.90 ), PBO: - 2.02 (95% CI: - 4.03 , 0.04)], and the percentage increase in blood DMAs (bDMAs) concentrations for the FA-treated groups significantly exceeded that of PBO [400FA: 12.8 (95% CI: 10.5, 15.2), 800FA: 11.3 (95% CI: 8.95, 13.8), creatine + 400 FA : 7.45 (95% CI: 5.23, 9.71), PBO: - 0.15 (95% CI: - 2.85 , 2.63)]. The mean decrease in PMI and increase in SMI in all FA groups significantly exceeded PBO (p < 0.05 ). Data from week 24 showed evidence of a reversal of treatment effects on As metabolites from week 12 in those who switched from 800FA to PBO, with significant decreases in SMI [- 9.0 % (95% CI: - 3.5 , - 14.8 )] and bDMAs [- 5.9 % (95% CI: - 1.8 , - 10.2 )], whereas PMI and bMMAs concentrations continued to decline [- 7.16 % (95% CI: - 0.48 , - 14.3 ) and - 3.1 % (95% CI: - 0.1 , - 6.2 ), respectively] for those who remained on 800FA supplementation. CONCLUSIONS FA supplementation lowered bMMAs and increased bDMAs in a sample of primarily folate-replete adults, whereas creatine supplementation lowered bMMAs. Evidence of the reversal of treatment effects on As metabolites following FA cessation suggests short-term benefits of supplementation and underscores the importance of long-term interventions, such as FA fortification. https://doi.org/10.1289/EHP11270.

Abstract
The objective of this "proof-of-concept" study was to evaluate the synergistic effect of a subunit microparticulate vaccine and microneedles (MN) assisted vaccine delivery system against a human coronavirus. Here, we formulated PLGA polymeric microparticles (MPs) encapsulating spike glycoprotein (GP) of SARS-CoV as the model antigen. Similarly, we formulated adjuvant MPs encapsulating Alhydrogel® and AddaVax™. The antigen/adjuvant MPs were characterized and tested in vitro for immunogenicity. We found that the antigen/adjuvant MPs were non-cytotoxic in vitro. The spike GP MPs + Alhydrogel® MPs + AddaVax™ MPs showed enhanced immunogenicity in vitro as confirmed through the release of nitrite, autophagy, and antigen presenting molecules with their co-stimulatory molecules. Next, we tested the in vivo efficacy of the spike GP MP vaccine with and without adjuvant MPs in mice vaccinated using MN. The spike GP MPs + Alhydrogel® MPs + AddaVax™ MPs induced heightened spike GP-specific IgG, IgG1 and IgG2a antibodies in mice. Also, spike GP MPs + Alhydrogel® MPs + AddaVax™ MPs enhanced expression of CD4+ and CD8+ T cells in secondary lymphoid organ like spleen. These results indicated spike GP-specific humoral immunity and cellular immunity in vivo. Thus, we employed the benefits of both the subunit vaccine MPs and dissolving MN to form a non-invasive and effective vaccination strategy against human coronaviruses.

Abstract
Respiratory syncytial virus (RSV) is an infectious disease that poses a significant public health risk in young children. Vaccine studies conducted in the 1960s using an intramuscular injection of formalin-inactivated respiratory syncytial virus (Fi-RSV) resulted in an enhanced respiratory disease and led to the failure of the vaccine. Thus, the virus-like particles (VLP) of the RSV fusion (F) protein was used as the vaccine antigen in this study. The F-VLP was encapsulated in a microparticle (MP) matrix composed of cross-linked bovine serum albumin (BSA) to enhance the antigen presentation and uptake. Moreover, a painless vaccination method would be desirable for an infectious disease that mainly affects young children. Thus, an ablative laser device, Precise Laser Epidermal System (P.L.E.A.S.E), was utilized to create micropores on the skin for vaccine delivery. We observed enhanced antigen presentation of the vaccine microparticles (F-VLP MP) with and without the adjuvant monophosphoryl lipid A (MPL-A) MP in dendritic cells. Consequently, Swiss Webster mice were immunized with the adjuvanted vaccine microparticles using the P.L.E.A.S.E laser to study the in vivo immunogenicity. The immunized mice had high serum immunoglobulin (IgG, IgG2a) levels, indicating a Th1 response. Subsequent analysis of lung homogenates post- RSV challenge revealed high IgA, indicating generation of a mucosal immune response upon intradermal immunization. Flowcytometry analysis showed high CD8+, and CD4+ expression in the lymph node and spleen of the adjuvanted vaccine microparticle immunized mice. Increased expression of interferon gamma (IFN-γ) in the spleen cells further proved Th1 polarized immune response. Finally, an immune plaque assay indicated significantly low lung viral titer in the mice immunized with intradermal adjuvanted vaccine microparticles. Thus, ablative laser-assisted immunization with the F-VLP based adjuvanted vaccine microparticles could be a promising vaccine candidate for RSV.

Abstract
Research on the use of biodegradable polymers for drug delivery has been ongoing since they were first used as bioresorbable surgical devices in the 1980s. For tissue engineering and drug delivery, biodegradable polymer poly-lactic-co-glycolic acid (PLGA) has shown enormous promise among all biomaterials. PLGA are a family of FDA-approved biodegradable polymers that are physically strong and highly biocompatible and have been extensively studied as delivery vehicles of drugs, proteins, and macromolecules such as DNA and RNA. PLGA has a wide range of erosion times and mechanical properties that can be modified. Many innovative platforms have been widely studied and created for the development of methods for the controlled delivery of PLGA. In this paper, the various manufacturing processes and characteristics that impact their breakdown and drug release are explored in depth. Besides different PLGA-based nanoparticles, preclinical and clinical applications for different diseases and the PLGA platform types and their scale-up issues will be discussed.

Abstract
Objective:
Marinobufagenin (MBG), a cardiotonic steroid, is distinctly elevated in preeclampsia (preE) and may directly contribute to pathogenesis, possibly through deleterious signaling in cytotrophoblast (CTB) cells. In this study, we evaluate the effects of anti-MBG human monoclonal antibodies on cellular signaling in CTB cells and in a rat model of preE.
Methods:
CTB cell proliferation in response to MBG with and without anti-MBG was measured using a Cell Titer assay. Pro-angiogenic factors (VEGF and PlGF) and anti-angiogenic factors (sFlt-1 and sEng) in response to MBG with and without antibody were measured. Finally, we evaluated the lead anti-MBG antibody in comparison with the parent murine antibody in a previously described rat model of preE which recapitulates the hypertension, proteinuria, and fetal growth effects of human preE.
Results:
CTB cells exposed to ≥ 1 nM MBG showed decreased (
p
< 0.05) proliferation, decreased secretion of VEGF and PIGF, and increased secretion of sFlt-1 and sEng. Pretreatment with anti-MBG significantly (
p
< 0.05) attenuated the MBG-induced modulation of cell proliferation and expression of VEGF, PIGF, sFlt-1, and sEng. In the rat model, anti-MBG treatment normalized blood pressure, reduced proteinuria, and eliminated fetal effects.
Conclusions:
MBG has the potential to be a causative agent for preE as it causes dysfunction in CTB cells due to the anti-angiogenic milieu. Our study suggests that anti-MBG antibodies can bind to MBG, neutralizing it, and preventing downstream signaling
in vitro.
In a saline-induced rat model of preE, treatment with anti-MBG antibody was effective at normalizing blood pressure, kidney function, and fetal birth weights. These data suggest that a human monoclonal antibody with high specificity and affinity for MBG has potential as a therapeutic for preE.

Abstract
Indonesia is among the top three countries globally with the highest tuberculosis burden. During the past decades, Indonesian health authorities have struggled to improve tuberculosis care quality in health care facilities by optimizing the regulation and strengthening the private sector contributions. The coronavirus disease 2019 (COVID-19) pandemic has hardly affected the Indonesian health care system, including the National Tuberculosis Control Program. While the end of the COVID-19 pandemic in Indonesia is uncertain, the measure to control tuberculosis must not be weakened. Early identification and measurement of the problem size are essential to decide the most appropriate approach to maintain the sustainability of National Tuberculosis Control Program, particularly in health care facilities during the COVID-19 pandemic. This article points out the possible threats to the sustainability of TB care in Indonesia during the COVID-19 pandemic, including some approaches to overcome those problems.

Abstract
Background: Blumea lacera (B. lacera) is a herbaceous plant commonly found in south-east Asia. It shows significant therapeutic activities against various diseases. The objectives of this study were to evaluate hepatoprotective effects of Blumea lacera leaf extract and also to investigate the comparative effectiveness between a liposomal preparation and a suspension of B. lacera leaf extract against carbon tetrachloride (CCl4)-induced liver damage. Methods: B. lacera leaf extract was characterized using a GC-MS method. A liposomal preparation of B. lacera leaf extract was developed using an ethanol injection method and characterized using dynamic light scattering (DLS) and electronic microscopic systems. The hepatoprotective effects of B. lacera leaf extracts and its liposomal preparation were investigated using CCl4-induced liver damage in Long Evan rats. Results: GC-MS data showed the presence of different components (e.g., phytol) in the B. lacera leaf extract. DLS and microscopic data showed that a liposomal preparation of B. lacera leaf extracts was in the nano size range. In vivo study results showed that liposomal preparation and a suspension of B. lacera leaf extract normalized liver biochemical parameters, enzymes and oxidative stress markers which were elevated due to CCl4 administration. However, a liposomal formulation of B. lacera leaf extract showed significantly better hepatoprotective effects compared to a suspension of leaf extract. In addition, histopathological evaluation showed that B. lacera leaf extract and its liposomal preparation treatments decreased the extent of CCl4-induced liver inflammations. Conclusion: Results demonstrated that B. lacera leaf extract was effective against CCl4-induced liver injury possibly due to the presence of components such as phytol. A liposomal preparation exhibited significantly better activity compared to a B. lacera suspension, probably due to improved bioavailability and stability of the leaf extract.

Abstract
BACKGROUND Associations of arsenic (As) with the sum of 5-mC and 5-hmC levels have been reported; however, As exposure-related differences of the separated 5-mC and 5-hmC markers have rarely been studied. METHODS In this study, we evaluated the association of arsenic exposure biomarkers and 5-mC and 5-hmC in 30 healthy men (43-55 years) from the Aragon Workers Health Study (AWHS) (Spain) and 31 healthy men (31-50 years) from the Folic Acid and Creatinine Trial (FACT) (Bangladesh). We conducted 5-mC and 5-hmC profiling using Infinium MethylationEPIC arrays, on paired standard and modified (ox-BS in AWHS and TAB in FACT) bisulfite converted blood DNA samples. RESULTS The median for the sum of urine inorganic and methylated As species (ΣAs) (μg/L) was 12.5 for AWHS and 89.6 for FACT. The median of blood As (μg/L) was 8.8 for AWHS and 10.2 for FACT. At a statistical significance p-value cut-off of 0.01, the differentially methylated (DMP) and hydroxymethylated (DHP) positions were mostly located in different genomic sites. Several DMPs and DHPs were consistently found in AWHS and FACT both for urine ΣAs and blood models, being of special interest those attributed to the DIP2C gene. Three DMPs (annotated to CLEC12A) for AWHS and one DHP (annotated to NPLOC4) for FACT remained statistically significant after false discovery rate (FDR) correction. Pathways related to chronic diseases including cardiovascular, cancer and neurological were enriched. CONCLUSIONS While we identified common 5-hmC and 5-mC signatures in two populations exposed to varying levels of inorganic As, differences in As-related epigenetic sites across the study populations may additionally reflect low and high As-specific associations. This work contributes a deeper understanding of potential epigenetic dysregulations of As. However, further research is needed to confirm biological consequences associated with DIP2C epigenetic regulation and to investigate the role of 5-hmC and 5-mC separately in As-induced health disorders at different exposure levels.

Abstract
Rapid spread of multidrug resistant microorganisms is a matter of great concern throughout the glove including Bangladesh. The objective was to identify the causative organisms for urinary tract infection (UTI) and their sensitivity patterns to antibiotics. This descriptive cross-sectional study was conducted on patients admitted with UTI (n=60) at a tertiary level hospital in Dhaka, Bangladesh from March 2019 to September 2019. Data were collected through clinical record reviews. Data of all these 60 cases were analyzed for socio-demographic characteristics. Of the 60 patients, culture and sensitivity report was available for 42 patients. Therefore, data were further analyzed for these 42 cases. Median age of patients was 35 years and 80% were female. The main organisms isolated from urine culture of UTI patients were E. coli (64%), Klebsiella (12%) and Enterococci species (10%). Susceptibility to antibiotics was analyzed only for E. coli (n=27) since the number of isolates of other organisms were small. E. coli was found to be resistant to most of the first- and second-line antibiotics, such as Amoxicillin (100%), Amoxyclav (72%), Co-trimoxazole (89%), Nalidixic acid (78%), Ceftazidim (94%), Ceftriaxone (73%), Cefuroxime (100%), Ciprofloxacin (59%), Cephotaxime (80%), Cefixime (100%) and Moxifloxacin (100%). E. coli was the predominant organism responsible for UTI and was resistant to most of the first- and second-line antibiotics. Immediate action is needed to develop empirical guideline for empirical management of UTI and establish surveillance system for monitoring.

Abstract
First detected in Wuhan, China, a highly contagious coronavirus, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), also known as COVID-19, spread globally in December of 2019. As of 19 September 2021, approximately 4.5 million people have died globally, and 215 million active cases have been reported. To date, six vaccines have been developed and approved for human use. However, current production and supply capabilities are unable to meet global demands to immunize the entire world population. Only a few countries have been able to successfully vaccinate many of their residents. Therefore, an alternative vaccine that can be prepared in an easy and cost-effective manner is urgently needed. A vaccine that could be prepared in this manner, as well as can be preserved and transported at room temperature, would be of great benefit to public health. It is possible to develop such an alternative vaccine by using nano- or microparticle platforms. These platforms address most of the existing vaccine limitations as they are stable at room temperature, are inexpensive to produce and distribute, can be administered orally, and do not require cold chain storage for transportation or preservation. Particulate vaccines can be administered as either oral solutions or in sublingual or buccal film dosage forms. Besides improved patient compliance, the major advantage of oral, sublingual, and buccal routes of administration is that they can elicit mucosal immunity. Mucosal immunity, along with systemic immunity, can be a strong defense against SARS-CoV-2 as the virus enters the system through inhalation or saliva. This review discusses the possibility to produce a particulate COVID vaccine by using nano- or microparticles as platforms for oral administration or in sublingual or buccal film dosage forms in order to accelerate global vaccination.

Abstract
In December 2019, a new and highly pathogenic coronavirus emerged-coronavirus disease 2019 (COVID-19), a disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), quickly spread throughout the world. In response to this global pandemic, a few vaccines were allowed for emergency use, beginning in November 2020, of which the mRNA-based vaccines by Moderna (Moderna, Cambridge, MA, USA) and BioNTech (BioTech, Mainz, Germany)/Pfizer (Pfizer, New York, NY, USA) have been identified as the most effective ones. The mRNA platform allowed rapid development of vaccines, but their global use is limited by ultracold storage requirements. Most resource-poor countries do not have cold chain storage to execute mass vaccination. Therefore, determining strategies to increase stability of mRNA-based vaccines in relatively higher temperatures can be a game changer to address the current global pandemic and upcoming new waves. In this review, we summarized the current research strategies to enhance stability of the RNA vaccine delivery system.

Abstract
With the need for safe and efficacious vaccines which could be administered via non-invasive procedure, alternatives to traditional injectables vaccines are sought after. The present study aimed to develop the microparticulate formulation of measles vaccine and explore the feasibility of transdermal delivery via ablative laser mediated skin microporation. Transdermal route offers several advantages including painless immunization and ease of administration. We propose to use P.L.E.A.S.E. ablative laser for transdermal immunization of the microparticulate measles vaccine. This laser emits energy at 2940 µm, enabling cold ablation. This creates the micropores of defined size for delivery of vaccines into the skin. We compared the efficacy of transdermal immunization using the particulate formulation of the vaccine to that of traditional subcutaneous immunization using soluble and particulate vaccine. The microparticles were formulated using the biocompatible and biodegradable bovine serum albumin (BSA)-based polymer matrix. These vaccine microparticles were non-cytotoxic to the antigen presenting cells (APCs) and could effectively stimulate the innate immune response, confirmed by release of nitric oxide (NO) from the Griess's assay. The APCs when exposed to vaccine microparticles also showed a significantly higher expression of antigen-presenting molecules, MHC I and MHC II, and their co-stimulatory molecules, CD80 and CD40 as compared to the blank microparticles. The microparticulate measles vaccine was evaluated in vivo in the murine model. We compared the serum IgG and IgM levels in the mice receiving the vaccine subcutaneously and transdermally post-immunization. The results revealed that transdermal immunization with microparticulate vaccine is as efficient as the traditional subcutaneous administration.

Abstract
Adjuvants potentiate the immune response against co-inoculated antigens in the vaccine formulation. Based on the mechanism of action, the adjuvants are classified as immunostimulatory adjuvants and vaccine delivery systems. (S)-4,5-Dihydroxy-2,3-pentanedione (DPD) is the precursor of bacterial quorum sensing molecule, autoinducer (AI)-2. We tested the immunogenicity and adjuvant potential of microparticulate formulation of (S)-DPD via in vitro evaluation. By formulating the microparticles of (S)-DPD, we consolidated the advantages of both the classes of adjuvants. The microparticulate (S)-DPD was tested for its immunogenicity and cytotoxicity. We further tested its adjuvant effect by combining it with particulate vaccines for measles and gonorrhea and compared the adjuvant effect observed with the microparticulate formulations of the FDA-approved adjuvants alum, MPL A®, and MF59®. Microparticulate (S)-DPD was found to be non-cytotoxic towards the antigen-presenting cells and had an adjuvant effect with microparticulate gonorrhea vaccine. Further studies with additional bacterial vaccines and the in vivo evaluation will confirm the potential of microparticulate (S)-DPD as a probable vaccine adjuvant candidate.

Abstract
Transdermal vaccination route using biodegradable microneedles is a rapidly progressing field of research and applications. The fear of painful needles is one of the primary reasons most people avoid getting vaccinated. Therefore, developing an alternative pain-free method of vaccination using microneedles has been a significant research area. Microneedles comprise arrays of micron-sized needles that offer a pain-free method of delivering actives across the skin. Apart from being pain-free, microneedles provide various advantages over conventional vaccination routes such as intramuscular and subcutaneous. Microneedle vaccines induce a robust immune response as the needles ranging from 50 to 900 μm in length can efficiently deliver the vaccine to the epidermis and the dermis region, which contains many Langerhans and dendritic cells. The microneedle array looks like band-aid patches and offers the advantages of avoiding cold-chain storage and self-administration flexibility. The slow release of vaccine antigens is an important advantage of using microneedles. The vaccine antigens in the microneedles can be in solution or suspension form, encapsulated in nano or microparticles, and nucleic acid-based. The use of microneedles to deliver particle-based vaccines is gaining importance because of the combined advantages of particulate vaccine and pain-free immunization. The future of microneedle-based vaccines looks promising however, addressing some limitations such as dosing inadequacy, stability and sterility will lead to successful use of microneedles for vaccine delivery. This review illustrates the recent research in the field of microneedle-based vaccination.

Abstract
Introduction: Substance use disorder has been frequently reported to increase the risk of infectious diseases, which might be owing to the sharing of contaminated inhalation, smoking, vaping, or injection equipment. Aim: This review analyzes the recent literature with the aim to put in light the possible relationship between the abuse of different substances (Tobacco, opioid, and Alcohol) with coronavirus disease (COVID-19). Tobacco: Multiple studies confirmed that cigarette smoking affects the respiratory system by increasing the expression of angiotensin-converting enzyme-2 (ACE2) receptors, which have a significant association with COVID-19 infection rate and disease severity. Opioid: Studies conducted regarding the association of opioid use disorder (OUD) and COVID-19 infection severity are limited; however, opioids can lead to both respiratory depression and kidney injuries, causing poor prognosis for those with COVID-19 infections. Alcohol: People with alcohol use disorders are at risk of developing acute lung injury and severe COVID-19 infection. Alcohol consumption during the COVID-19 pandemic has two possible scenarios: either increased or decreased based on situations. Conclusion: SUD has been frequently reported to have a positive relationship with COVID-19 severity Further studies are needed to understand the effects of opioids and alcohol abuse on COVID-19.

Abstract
PURPOSE Methylation of ingested inorganic arsenic (InAs) to monomethyl- (MMAs) and dimethyl-arsenical species (DMAs) facilitates urinary arsenic elimination. Folate and creatine supplementation influenced arsenic methylation in a randomized controlled trial. Here, we examine if baseline status of one-carbon metabolism nutrients (folate, choline, betaine, and vitamin B12) modified the effects of FA and creatine supplementation on changes in homocysteine, guanidinoacetate (GAA), total blood arsenic, and urinary arsenic metabolite proportions and indices. METHODS Study participants (N = 622) received 400 or 800 μg FA, 3 g creatine, 400 μg FA + 3 g creatine, or placebo daily for 12 weeks. RESULTS Relative to placebo, FA supplementation was associated with greater mean increases in %DMAs among participants with betaine concentrations below the median than those with levels above the median (FDR < 0.05). 400 μg FA/day was associated with a greater decrease in homocysteine among participants with plasma folate concentrations below, compared with those above, the median (FDR < 0.03). Creatine treatment was associated with a significant decrease in %MMAs among participants with choline concentrations below the median (P = 0.04), but not among participants above the median (P = 0.94); this effect did not significantly differ between strata (P = 0.10). CONCLUSIONS Effects of FA and creatine supplementation on arsenic methylation capacity were greater among individuals with low betaine and choline status, respectively. The efficacy of FA and creatine interventions to facilitate arsenic methylation may be modified by choline and betaine nutritional status.

Abstract
Suicide is one of the important cause of death worldwide. The precise effect of childhood adversities as risk factors for the onset and persistence of suicidal behaviour are not well understood. A descriptive cross sectional study was carried out in the department of Psychiatry, Cumilla Medical College, Cumilla, Bangladesh. All cases were selected from patients attending at Cumilla Medical College hospital and Private Hospitals in Cumilla City from April 2017 to September 2018. We found out the association between childhood adversities and suicidal behaviour over the life course and delineated the types of suicidal behavior. Total 120 cases were included in the study. Respondents provided socio-demographic and diagnostic information, childhood adversities as well as an account of suicide-related thoughts and behaviours. A participation rate was 77.5% female. Of 120 suicidal behavior participants physical abuse was 2.5%, sexual abuse was 16.67%, parental death was 5%, parental divorce was 2.5%, other parental loss was 4.17%, family violence was 5%, physical illness was 1.67%, financial adversity was 3.33% and composite adversity was 59.16%. Among childhood adversities participants suicidal ideation was 70%, suicidal plans was 15.83%, suicidal attempts was 45%, ideators only proceeded to plans was 22.5%, ideation to attempt was 63.33%, planned attempts was 10.83% and impulsive attempts was 52.5%. Among suicidal behavior participant's psychiatric disorders were 65%. Where neurotic disorders were 17%, psychotic disorders were 13%, personality disorders were 44% and others disorder was 26%. Most of the suicidal behavior patients were female 77.5% and age group of 18-24 years. Childhood sexual abuse emerged as a particularly robust risk factor for suicide attempts in younger participants. Childhood physical and sexual abuse emerged as risk factors for the emergence and persistence of suicidal behaviour, especially in adolescence. Two or more childhood adversities were associated with a three fold higher risk of lifetime suicide attempts. Childhood adversities are main risk factors for the onset and persistence of suicidal behaviour. The risks being are the greatest in childhood, adolescence and early adult. A longitudinal follow-up study is required to give a more reliable in Bangladesh.

Abstract
Objective:
Preeclampsia (preE), a syndrome of hypertension, and end organ damage, is a leading cause of maternal and fetal morbidity and mortality. Recently, we and other researchers have shown that circulating (pro)renin, soluble (pro)renin receptor (s(P)RR) and placental (P)RR were significantly higher during preE compared to normal pregnancy (NP). In this study, placental expression of (P)RR and serum s(P)RR were evaluated in preE human patients and various rat models of preE.
Study Design:
(1) Placenta and blood samples were collected from 40 NP and 30 consented preE patients; (2) expression of (P)RR in placenta and soluble (P)RR were evaluated in two established preE rat models: reduced uterine perfusion pressure (RUPP) and deoxycorticosterone acetate (DOCA; PDS) models of preE and were compared to normal pregnant (NP) (SD) rats (n=8). We measured the expression of (P)RR by western blotting (WB) and immunohistochemistry. Plasma (pro)renin and s(P)RR were detected using a commercially available ELISA Kit.
Results:
The placental expression of (P)RR was higher (p*<0.05) in human preE patients compared to normal pregnant women as evaluated by WB and IHC. The s(P)RR was significantly (p*<0.05) higher in human patients with preE (preE: 31.2 ± 3.15 vs NP:19.6 ± 2.9 ng/mL) . Plasma levels of pro(renin) (normalized to angiotensin I, AngI) (preE: 49.2 ± 10 vs NP: 22.7 ± 4.3 ng/AngI/mL/h) and s(P)RR (preE: 31.2 ± 3.15 vs NP:19.6 ± 2.9 ng/mL) are significantly (p*<0.05; in each case) higher in DOCA rats (PDS) compared to normal pregnant (NP) (*p<0.05). Plasma s(P)RR is significantly (p*<0.05) elevated in RUPP rats (20.06 ± 2.17 ng/mL) compared to NP rats (11.2 ± 2.1 ng/mL). Similarly, plasma (pro)renin is significantly (p*<0.05) elevated in the RUPP group (38.1 + 3.86 (ng/AngI/mL/h) compared to NP rats (21.2 + 3.25 (ng/AngI/mL/h). In the RUPP and DOCA models, both PRR and s(P)RR are approximately doubled compared to controls.
Conclusions:
These data suggest that increased expression of (P)RR in the placenta and s(P)RR are associated with placental ischemia related to the occurrence of preE in both human patients and animal models of disease.

Abstract
Background:
Preeclampsia (PreE) is a pregnancy disorder characterized by new onset of hypertension and reduced fetal weight. We have previously shown that marinobufagenin (MBG) and hyperglycemia impairs cytotrophoblasts (CTBs) function. The potential therapeutic role of H2 relaxin in PreE was reported, a novel H2 relaxin B-chain-only peptide B7-33 and its lipidated derivative have recently been developed. This study evaluates whether B7-33 and its lipidated derivative improve CTBs function and preE phenotype.
Methods:
A palmitic acid was attached at the N-terminus of B7-33. Human CTBs were treated with DMSO (vehicle) or 0.1, 1, 10 or 100 nM of MBG or with 100, 150, 200, 300, or 400 mg/dL glucose for 48h and were co-treated either with B7-33 (25 nM) or its lipidated derivative (25 nM) in the presence and absence of either MBG or hyperglycemia exposure. Some cells were pretreated with relaxin antagonist (1.0 μM RXFP1) prior to MBG or hyperglycemia exposure. Levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), and soluble fms-like tyrosine kinase-1 (sFlt-1) were measured in culture media using ELISA kits. Statistical comparisons were performed using analysis of variance with Duncan’s post hoc test.
Results:
Lipidation of B7-33 results in a significant increase of half-life of B7-33 without altering its activity. Secretion of sFlt-1 was increased while VEGF and PIGF were decreased in CTBs treated with ≥1.0 nM MBG and ≥150 mg/dl of glucose (*p < 0.05 for each). Co-treatment with B7-33 (25 nM) and its lapidated derivative (25 nM) rescued CTBs from either MBG-induced and hyperglycemia-induced anti-angiogenic profile (p < 0.05 for each). B7-33 and its lapidated derivative cause an increase in the expression of VEGF in CTBs, however, they have no effect on other factors. The B7-33-induced upregulation of VEGF expression is attenuated by 1.0 μM RXFP1 antagonist.
Conclusion:
Both B7-33 and its lipidated derivative mitigate the MBG- and hyperglycemia-induced dysfunction of CTBs by attenuating anti-angiogenic phenotype similar to that seen in preE. Moreover, the B7-33 and its lipidated derivative induced effect on CTBs are attenuated by a relaxin antagonist. The preclinical study with B7-33 and its lipidated derivative are now underway.

Abstract
Background Arsenic exposure through drinking water persists in many regions. Inorganic As (InAs) is methylated to monomethyl-arsenical species (MMAs) and dimethyl-arsenical species (DMAs), facilitating urinary excretion. Arsenic methylation is dependent on one-carbon metabolism, which is influenced by nutritional factors such as folate and creatine. Objective This study investigated the effects of folic acid (FA) and/or creatine supplementation on the proportion of As metabolites in urine. Design In a 24-wk randomized, double-blinded, placebo-controlled trial, 622 participants were assigned to receive FA (400 or 800 μg per day), 3 g creatine per day, 400 μg FA + 3 g creatine per day, or placebo. The majority of participants were folate sufficient; all received As-removal water filters. From wk 12-24, half of the participants receiving FA received placebo. Results Among groups receiving FA, the mean decrease in ln(%InAs) and %MMAs and increase in %DMAs exceeded those of the placebo group at wk 6 and 12 (P < 0.05). In the creatine group, the mean decrease in %MMAs exceeded that of the placebo group at wk 6 and 12 (P < 0.05); creatine supplementation did not affect change in %InAs or %DMAs. The decrease in %MMAs at wk 6 and 12 was larger in the 800 µg FA than in the 400 µg FA group (P = 0.034). There were no differences in treatment effects between the 400 µg FA and creatine + FA groups. Data suggest a rebound in As metabolite proportions after FA cessation; at wk 24, log(%InAs) and %DMAs were not significantly different than baseline levels among participants who discontinued FA supplementation. Conclusions The results of this study confirm that FA supplementation rapidly and significantly increases methylation of InAs to DMAs. Further research is needed to understand the strong cross-sectional associations between urinary creatinine and As methylation in previous studies. This trial was registered at https://clinicaltrials.gov as NCT01050556.

Abstract
A 33-year-old man with anti-phospholipid antibody syndrome associated with Budd Chiari syndrome and subdural hematoma. He developed venous thrombosis in his hepatic vein (stenting done) when laboratory studies demonstrated prolongation of activated partial thromboplastin time (APTT). Subdural hematoma demonstrated with Computed tomography (CT) of brain. Laboratory studies revealed thrombocytopenia, prolonged bleeding time and APTT, positive antinuclear antibody and positive test results for both lupus anticoagulant and an anti-cardiolipin antibody, namely antiphospholipid antibodies. Based on these findings, we consider that the tendency of this bleeding may have been due to antiphospholipid antibodies, attacking the platelet membranes and that the bridging veins in the subdural space may be the site at which the bleeding tendency easily appears. Antiphospholipid antibody syndrome accompanied by hemorrhagic complications had rarely been reported. We suggest that special attention should be given to hemorrhagic complications in patients with antiphospholipid antibody syndrome associated with fragility of the vessels and/or platelet dysfunction and on anticoagulant (warfarin).Pulse Vol.10 January-December 2017 p.25-28

Abstract
BACKGROUND/AIM Cinobufotalin (CINO), a cardiotonic steroid, has been used as an anticancer agent. This study assessed the cell-specific effect of CINO on SK-OV-3, CRL-1978 and CRL-11731 ovarian cancer cells which differ in terms of their respective karyotypes. MATERIALS AND METHODS Cell cultures were treated with CINO (0.1, 1, 5 and 10 μM) for 24, 48, and 72 h. Cell proliferation, migration, and invasion were measured using CellTiter, Cytoselect, and FluoroBlock assays, respectively. Expression of proliferating cell nuclear antigen (PCNA) was evaluated by western blot analysis. Cell viability was determined by fluorescence-activated cell sorting. Immunofluorescence was performed using Annexin-V staining and fluorescein isothiocyanate (FITC). Mitochondrial membrane potential (MMP) was measured using MitoTracker™ Red. RESULTS CINO at 0.5 μM inhibited SK-OV-3, CRL-1978, and CRL-11731 proliferation, migration, and invasion. Each cell type differed in response to CINO doses for PCNA, Annexin-V expression and MMP. CONCLUSION The antineoplastic property of CINO is consistent, but its mode of action varies among cell lines.

Abstract
We conducted a study to evaluate the reliability of the medial hemi-soleus muscle flap for wound coverage of infected open fracture of distal third of tibia. Wound coverage of exposed lower third tibia and ankle region remains a difficult task. Muscle flaps are preferred for infected wounds especially where there are exposed bone, joint and/or tendons. Soleus muscle is a good option for local reconstruction. Soleus being the prime ankle plantar flexor and stabilizer of the ankle in ambulation cannot be sacrificed without significant morbidity. Soleus is a bipennate muscle with independent blood supply of each half. Using one half retains its important function, increases arc of rotation, and makes it easy to orientate for coverage of defect of any shape thus obviating the need for use of whole Soleus muscle flap. So, medial hemisoleus muscle flap is a superior option than the whole Soleus. This post-intervention prospective study which was descriptive in nature was conducted at department of Orthopedics, Community Based Medical College Hospital, Mymensingh, Bangladesh from January 2012 to December 2012. Ten patients with distal third tibial defects were included in the study. Data was obtained by history taking, observation, clinical examination, supported by routine laboratory and radiological investigations. Before intervention they underwent to careful vascular study of the affected limb through Doppler ultrasonography. All the patients were provided soft tissue coverage with distally based medial hemi-soleus muscle flaps with split thickness skin graft on it. All the flaps survived with primary healing of the wound. Among the participants there were 7 male and 3 female with average age 44.60 years, SD 13.73 years. Eight patients were injured by road traffic accident and 2 patients had history of alleged assault. The wound size defects in primary site ranged from 4cm to 9cm in length and 3cm to 6.5cm in breadth. All the wounds in the primary site were infected. The fractures in the primary site were open fractures involving distal third of tibia. In the secondary site the injuries were fracture upper third tibia in the other lower limb 2, fracture femur on other lower limb 1, dislocation shoulder joint on the same side upper limb 1. The follow up period ranged from 8-16 weeks (average 12 weeks). The outcome was successful. All flaps survived without complication. Hemisoleus muscle flap is a valuable local option for soft tissue coverage of distal third of leg. It does not sacrifice the whole soleus muscle. Due to its longer arc of rotation, this flap can cover the defect of different size and shape in distal third of leg.

Abstract
BACKGROUND/AIM 3,4',7-O-trimethylquercetin (34'7TMQ), a derivative of quercetin, inhibited ovarian cancer cell migration and invasion without affecting proliferation. In this study, the apoptotic effect of 34'7TMQ on three cancer cell lines (CRL-1978, CRL-11731, SK-OV-3) was evaluated. MATERIALS AND METHODS Expression of pro-apoptotic proteins such as Bax/Bcl-2 ratio, p38 MAP kinase, and caspase-9 were measured by western blot analysis. Annexin-V staining was performed to visualize apoptotic signaling. RESULTS Caspase-9 was up-regulated in all three cell lines. Bax/Bcl-2 ratio was up-regulated in CRL-1978 and SK-OV-3 but down-regulated in CRL-11731. The p38 MAPK was down-regulated in CRL-1978, up-regulated in SK-OV-3, and had differential expression in CRL-11731. Annexin V staining indicated that 34'7TMQ at 6.25 μM induced apoptotic signaling in the CRL-1978 ovarian cancer cell line. CONCLUSION 34'7TMQ induced apoptosis in three types of cancer cell lines but it appears to have a different mechanism of action in each cell line.

Abstract
Background:
Previous work has shown an increase in urinary excretion of marinobufagenin (MBG) in patients with preeclampsia (preE) compared to normal pregnancy at delivery. MBG is a novel urinary marker for preE; however, it is unknown how MBG levels fluctuate during gestation.
Hypothesis:
Shifts in MBG and angiogenic factors during early pregnancy identify cytotrophoblast’s dysfunction, contributing to reduced vascular development with impaired perfusion and preE.
Methods:
In this study, we prospectively enrolled two groups of patients; 50 patients in each group total of 100 patients for serial collection of urine and serum during each trimester and at delivery. These groups are: (1) Pregnant women at risk for development of preE; and (2) Pregnant women at low risk for development of preE. Risks were calculated for each pregnancy using the sum of relative risk values. Urine samples from 100 subjects (100 in first trimester, 67 in second trimester, 67 third trimester, and 67 at delivery) were assayed using ELISA for MBG (Panorama Research, Inc.), sENG, VEGF, PIGF, sFlt-1 expressed as pg/mg creatinine and the calculated uFP (log of 10x sFLT-1/PIGF ratio). The angiogenic factors were analyzed by commercially available kits.
Results:
Of 100 subjects, 50 had no risk for preE and 50 had relative risks on the average of 6.6 with a range of 1.4 to 16.6. There were no associations between relative risk and any of the 6 angiogenic measures during the first trimester (p > 0.36) and second trimester (p > 0.22) using linear regression. However, during the second trimester, the high risk cohort had lower PIGF levels than the no risk cohort (p < 0.05 using Mann-Whitney U test). Comparing the serial values of 6 angiogenic measures in 67 subjects during the first, second, third trimesters and at deliveries, only MBG and PIGF varied significantly (p < 0.05) with MBG.
Conclusions:
MBG increases with progression of pregnancy and the levels of MBG are the highest during delivery. We conclude that MBG levels increase during normal pregnancy, however, the differential levels of MBG in normal and preE pregnancies are now underway. Relationships to development of preE symptoms and MBG levels are pending with the addition of patients and additional sample.

Abstract
BACKGROUND/AIM Methylquercetin, 3,4',7-O-trimethylquercetin (34'7TMQ), has been reported to inhibit metastasis. Recently, we demonstrated that 34'7TMQ inhibited the in vitro melanoma B16 cell metastatic activity. We evaluated the effect of 34'7TMQ on three ovarian cancer cells (SK-OV-3, CRL11731 and CRL1978). MATERIALS AND METHODS Proliferation, migration and invasion were measured in 34'7TMQ-treated ovarian cancer cells by commercially available kits. We also evaluated the expression of proliferating cell nuclear antigen (PCNA), urokinase plasminogen activator (uPA), plasminogen activator inhibitor 1 (PAI-1) and matrix metalloproteinase (MMP)-2 by western blot analysis. RESULTS 34'7TMQ inhibited ovarian cancer cell migration and invasion without effecting proliferation. Furthermore, 34'7TMQ inhibited the expression of uPA and MMP-2; however, it had no effect on PAI-1 and PCNA. CONCLUSION 34'7TMQ significantly regulates the expressions of protein to inhibit metastasis in ovarian cancers, while the regulatory effects of 34'7TMQ vary between different ovarian cancer cell lines.

Abstract
Studies of the impact of mental disorders on educational attainment are rare. Mental disorders, those beginning in childhood or adolescence may increase the risk of early drop out from education. The latter has been shown to have adverse life-course consequences on individuals such as greater demand on social welfare entitlements. A descriptive cross sectional study was carried out at the department of Psychiatry, Comilla Medical College, Comilla, Bangladesh. All cases were selected from patients attending at Comilla Medical College Hospital and Private Mental Health Facilities in Comilla City from March 2015 to February 2016. We found out the psychiatric disorders and socio-demographic status of patients with educational drop out over the early life course. A total of 50 dropout patients aged 10 to 30 years who fullfiled the enrolment criteria included in the study. Sociodemographic questionnaires, diagnostic information (DSM-5 and ICD-10) as well as an account of a various level of education were used as research instruments. The Frequency tables, summary tables and appropriate graphs were prepared to describe the population characteristics and study finding. The most of the psychiatric morbidity presents in male (62%) and age group of 18-24 years (54%). In this study, anxiety disorders was 8%, behaviour/ impulse control disorders was 8%, mood disorders was 16%, substance use disorders was 24%, schizophrenia spectrum disorders was 12% and composite psychiatric disorders was 32%. Among drop out patient's non- completion of primary education was 14%, non-completion of secondary education was 20%, non- completion of higher secondary education was 24%, not entry to tertiary education was 12% and non-completion of tertiary education was 30%. Among behaviour/impulse control disorders non-completion of primary education was 6%, substance use disorders non-completion of higher secondary education was 10%, mood disorder both non-completion of higher secondary education and non-completion of tertiary education were 6%. Among composite psychiatric disorders non-completion of secondary education, non-completion of higher secondary education and non-completion of tertiary education were 8%, 6% and 12% respectively. Onset of mental disorders and subsequent drop out from education was found in this study. Further multi-centered prospective and population-based studies should be designed to find out the exact situation.

Abstract
BACKGROUND Posttranslational histone modifications (PTHMs) are altered by arsenic, an environmental carcinogen. PTHMs are also influenced by nutritional methyl donors involved in one-carbon metabolism (OCM), which may protect against epigenetic dysregulation. METHODS We measured global levels of three PTHMs, which are dysregulated in cancers (H3K36me2, H3K36me3, H3K79me2), in peripheral blood mononuclear cells (PBMC) from 324 participants enrolled in the Folic Acid and Creatine Trial, a randomized trial in arsenic-exposed Bangladeshi adults. Sex-specific associations between several blood OCM indices (folate, vitamin B12, choline, betaine, homocysteine) and PTHMs were examined at baseline using regression models, adjusted for multiple tests by controlling for the false discovery rate (PFDR). We also evaluated the effects of folic acid supplementation (400 μg/d for 12 weeks), compared with placebo, on PTHMs. RESULTS Associations between choline and H3K36me2 and between vitamin B12 and H3K79me2 differed significantly by sex (Pdiff < 0.01 and <0.05, respectively). Among men, plasma choline was positively associated with H3K36me2 (PFDR < 0.05), and among women, plasma vitamin B12 was positively associated with H3K79me2 (PFDR < 0.01). Folic acid supplementation did not alter any of the PTHMs examined (PFDR = 0.80). CONCLUSIONS OCM indices may influence PTHMs in a sex-dependent manner, and folic acid supplementation, at this dose and duration, does not alter PTHMs in PBMCs. IMPACT This is the first study to examine the influences of OCM indices on PTHMs in a population that may have increased susceptibility to cancer development due to widespread exposure to arsenic-contaminated drinking water and a high prevalence of hyperhomocysteinemia.

Abstract
Over 500,000 new cases of cervical cancer are diagnosed each year in the world, resulting in 250000 deaths. Prevalence of HPV-related cervical carcinoma in Bangladesh is highest among SAARC countries. In Bangladesh very few studies have been published on establishing the correlation between histological and cytological findings on cervical cancer and precancerous lesions. This descriptive cross-sectional study was performed to find out the correlation between histological & cytological findings of cervical cancer and precancerous lesions. In the present study, cervical smears were collected from the selected patients attending the colposcopy clinic of BSMMU from July 2011 to April 2013. Biopsy was done on colposcopically positive cases and histopathological reports were obtained. Thus 99 histologically proven cases of cervical cancer and precancerous lesion were selected. Pap smear was carried out on these 99 samples after histopathological examination. Among the 60 CIN-1 cases in histology, 18(30%) cases were diagnosed positive by Pap smear; out of 20 histologically diagnosed cases of CIN-II, only 12(60%) cases were correctly diagnosed by cytology. But in case of invasive squamous cell carcinoma 18 out of 19 were correctly diagnosed by Pap smear reaching a concordance rate of 94.74%. Overall the relation reached statistical significance (p<0.05). Larger community based studies are required in this respect to find a consistent correlation between hr-HPV load and cervical cancer and precancerous lesions.

Abstract
Background:
Relaxin is a peptide hormone that allows vasodilation and plays an important role in the process of parturition. The literature suggests potential therapeutic role of H2 relaxin in preeclampsia (PreE), however, there is a controversy on hypotensive action of the peptide. Due to the complex insulin-like structure of relaxin (A- and B- chains, 53 amino acids, 3 disulfide bonds), a novel H2 relaxin B-chain-only peptide variant B7-33 (27 amino acids without any disulfide bonds) has recently been developed. This single-chain peptide displayed equivalent efficacy to the natural H2 relaxin in several functional assays both
in vitro
and
in vivo
. Importantly, B7-33 was shown to have H2 relaxin-like RXFP1 specific effects, particularly in endogenously expressing RXFP1 cells, thus we hypothesized that B7-33 could be an alternative and cost-effective treatment option for PreE compared with H2 relaxin.
Methods:
Human CTBs were treated with 100, 150, 200, 300, or 400 mg/dL glucose for 48h and were co-treated with B7-33 (25 nM) with glucose exposure, while some cells were treated with 5, 10, 25 and 50 nM B7-33 alone. Levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1), and soluble endoglin (sEng) were measured in culture media using ELISA kits. Cell lysates were utilized to evaluate the mTOR, pAKT and total AKT expression by western blotting. Statistical comparisons were performed using analysis of variance with Duncan’s post hoc test.
Results:
Secretion of sFlt-1 and sEng were increased while VEGF and PIGF were decreased in CTBs treated with ≥150 mg/dl of glucose (*p < 0.05 for each). B7-33 co-treatment significantly rescued CTBs from hyperglycemia-induced anti-angiogenic profile (p < 0.05 for each). There is no effect of B7-33 on sFLT-1, sEng and PlGF; however, it increases expression of VEGF, while CTBs were treated only with B7-33. B7-33 also causes increased mTOR and pAKT expression in CTBs without any change in total AKT.
Conclusions:
B7-33 mitigates the hyperglycemia-induced dysfunction of CTBs by attenuating anti-angiogenic phenotype similar to that seen in PreE. This study supports the importance of continuing research of B7-33 in preE prevention.

Abstract
Background:
Preeclampsia (PreE) is de novo development of hypertension and proteinuria after 20 weeks of gestation with multiple pathophysiologic triggers affecting 3-8% of pregnancies. PreE has a significant link to alterations of feto-placental stress that pass to the offspring causing detrimental effects. We assessed and compared the pregnancy outcomes between patients with and without PreE.
Methods:
We recruited 35 normal pregnant (NP) and 25 PreE consenting patients in an IRB approved prospective study at Scott & White Memorial Hospital, Temple, Texas. We evaluated maternal age, body mass index (BMI), blood pressures, proteinuria, and gestational age at delivery. We divided the PreE subjects into early (before 34 weeks) and late PreE (after 34 weeks) groups and compared their outcomes. Placental thickness and volumes were measured. We also evaluated neonates for intrauterine growth restriction (IUGR), gestational age at birth, anthropometric measurements including Ponderal Index (PI), length of hospitalization and other neonatal complications. Comparisons were performed using Student’s t test.
Results: Maternal:
The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were higher in PreE (SBP 166 ± 11; DBP 93 ± 10) compared to normal pregnancies (SBP 122 ± 10; DBP 74 ± 9; p <0.05 for each case). PreE mothers had higher urinary protein excretion (457mg/24h ± 140) compared to NP (160 mg/24h ± 44; p <0.05 for each case). We did not find any difference in body mass index (BMI).
Placenta:
The placental thickness in early PreE subjects was 25mm compared to 32mm in late PreE (p <0.05) and placental volume in early PreE 296 cm
3
compared to 393cm
3
(p <0.05).
Neonatal:
The average GA at delivery was lower in PreE (34.8 wks. ± 4) compared to NP (39.2 weeks ± 0.3; p <0.05). Average hospital stay for PreE babies were longer (20 days ± 5) compared to NP (2 days ± 1; p <0.05). The PreE babies were SGA with lower PI (2.28 ± 0.3) compare to the NP babies (2.95 ± 0.2; p <0.05). Gestational age at delivery in early PreE is 32.4 weeks vs 36.8 weeks in late PreE (p <0.05). About 56% of the infants who are born to early PreE are small for gestational age (SGA) and 30% of the infants who are born to late PreE are SGA. PreE babies had multiple complications compared to NP babies.
