Abstract
Degradation of dyes under natural light sources is one of the most active research areas in basic science for greener technology. In this context, the photocatalytic activity of semiconductors has received massive attention in solving water treatment-related issues as these possess enormous potential for degrading organic impurities. Here, we report that barium aluminate (BaAl2O4, BAO), which has been extensively studied for photoluminescence applications, is found to be a highly potent candidate for photocatalytic activities. We have explored the degradation of dyes (meant for water purification) by using the photocatalytic properties of pure and Dy- and Yb-codoped BAO. Crystal structure, electron microscopy, and Raman analysis of the autocombustion-synthesized pure and codoped BAO samples revealed significant morphological changes such as increased particle size and stabilization of rod-like structures. UV-vis absorbance measurements confirm the presence of multiple bandgaps in the BAO samples, which is substantiated by X-ray absorption spectroscopy measurements. Photocatalytic degradation studies of methylene blue (MB) dye (with different catalyst concentrations, dopings, and MB dye concentrations) have been carried out by using BAO. The kinetics of the photocatalytic degradation measurements has been explained by the Boltzmann distribution function, and the fastest (in less than 40 min), with more than 99% degradation of MB impurity, is reported here for the first time in BAO compounds. Synthesized BAO samples show excellent cyclic stability, which is essential for their potential applications in environmental remediation. The trade-off between the enhancement of surface area and increased particle size is considered the key parameter for controlling the photocatalytic performance of the BAO catalyst after Dy and Yb codopings.

Abstract
BACKGROUND AND OBJECTIVES The novel tyrosine kinase inhibitor (TKI) dasatinib, a multitarget inhibitor of Bcr-Abl and Src family kinases, has been licensed for the treatment of Ph+ acute lymphoblastic leukemia and chronic myeloid leukemia. Many citrus-based foods include the flavonoid naringenin, which is commonly available. Dasatinib is a Cyp3a4, P-gp, and Bcrp1 substrate, which makes it sensitive to potential food-drug interactions. The concurrent use of naringenin may change the pharmacokinetics of dasatinib, which could result in adverse effects and toxicity. The present investigation examined the impact of naringenin on the pharmacokinetics interactions of DAS and proposes a possible interaction mechanism in Wistar rats. METHODS Rats were provided with a single oral dose of dasatinib (25 mg/kg) with or without naringenin pretreatment (150 mg/kg p.o. daily for 7 days, n = 6 in each group). Dasatinib was quantified in plasma by UHPLC MS/MS assay. Noncompartmental analysis was used to compute the pharmacokinetic parameters, and immunoblot was used to assess the protein expression in the hepatic and intestinal tissues. RESULTS Following 7 days of naringenin pretreatment, the plasma mean concentration of dasatinib was enhanced compared with without pretreatment. In rats that were pretreated with naringenin, the pharmacokinetics of the orally administered dasatinib (25 mg/kg) was shown to be significantly different from that of dasatinib given without pretreatment (p < 0.05). There was a significant enhancement in pharmacokinetic parameters elimination half-life (T1/2), time to maximum concentration ( Tmax), maximum concentration )Cmax), area under the concentration-time curve (AUC0-t), area under the moment curve (AUMC0-∞), and mean residence time (MRT) by 28.41%, 50%, 103.54%, 72.64%, 115.08%, and 15.19%, respectively (p < 0.05) and suppression in elimination rate constant (Kel), volume of distribution (Vd), and clearance (CL) by 21.09%, 31.13%, and 46.25%, respectively, in comparison with dasatinib alone group (p < 0.05). The enhancement in dasatinib bioavailability and systemic exposure resulted from the significant inhibition of Cyp3a2, Mdr1/P-gp, and Bcrp1 expression and suppression of the dasatinib hepatic and intestinal metabolism, which enhanced the rate of dasatinib absorption and decreased its elimination. CONCLUSION Concurrent use of naringenin-containing supplements, herbs, or foods with dasatinib may cause serious and potentially life-threatening drug interactions. Further studies are necessary to determine the clinical significance of these findings.

Abstract
Mn-substituted Cu and Zn co-doped spinel-typed nano-crystalline ferrites having nominal composition Ni0.50-xMnxCu0.15Zn0·35Fe2O4 (x = 0.00-0.25 in 0.05 increments) have been prepared through the citric acid assisted sol-gel auto-combustion technique. From the XRD measurements, it was found that several intense peaks ensured the cubic spinel-based ferrite structure beyond the formation of any impurity peaks. The crystallite sizes varied from 20 to 28 nm for ash-burnt powders following the coalescence process that decreased the lattice defects and strain. With an increase in Mn concentration, the hopping length (LA) of the tetrahedral A-site increases, while the hopping length (LB) of the octahedral B-site decreases with enhanced lattice constant. The sintered samples' average grain sizes, as measured using the Field Emission Scanning Micrographs (FESEM), differed from around 1.40 to 5.30 μm. Incorporating Mn-ion accelerates grain growth and crystallite size with increased bulk density and reduced porosity due to heat treatment. For increasing sintering temperature along with Mn concentration, porosity drops from 42% to 3%, resulting in enhancing the magnetic induction of the prepared ferrites. The 25% Mn substituted composition displays the maximum initial permeability (μ i ' = 315), which is ∼7 times larger than the pristine composition. Due to the reduction of Ni content, the relative quality factor rises but the magnetic loss tangent reduces. An increased trends of μ i ' are accompanied by decreased resonant frequency, obeying Snoek's law. According to the experimental findings, the high spin Mn substitution in the composition causes the saturation magnetization to increase while the coercivity and Néel temperature drop with increasing grain size. Hence, the locally prepared low-cost Nano-crystalline Ni-Mn-Cu-Zn ferrites bearing excellent properties can be a good candidate for promising future applications in nanotechnology.

Abstract
Named Data Networking (NDN) has emerged as a promising network architecture for content delivery in edge infrastructures, primarily due to its name-based routing and integrated in-network caching. Despite these advantages, sub-optimal performance often results from the decentralized decision-making processes of caching devices. This article introduces a paradigm shift by implementing a Software Defined Networking (SDN) controller to optimize the placement of highly popular content in NDN nodes. The optimization process considers critical networking factors, including network congestion, security, topology modification, and flowrules alterations, which are essential for shaping content caching strategies. The article presents a novel content caching framework, Popularity-aware Caching in Popular Programmable NDN nodes (PaCPn). Employing a multi-variant vector autoregression (VAR) model driven by an SDN controller, PaCPn periodically updates content popularity based on time-series data, including 'request rates' and 'past popularity'. It also introduces a controller-driven heuristic algorithm that evaluates the proximity of caching points to consumers, considering factors such as 'distance cost,' 'delivery time,' and the specific 'status of the requested content'. PaCPn utilizes customized DATA named packets to ensure the source stores content with a valid residual freshness period while preventing intermediate nodes from caching it. The experimental results demonstrate significant improvements achieved by the proposed technique PaCPn compared to existing schemes. Specifically, the technique enhances cache hit rates by 20% across various metrics, including cache size, Zipf parameter, and exchanged traffic within edge infrastructure. Moreover, it reduces content retrieval delays by 28%, considering metrics such as cache capacity, the number of consumers, and network throughput. This research advances NDN content caching and offers potential optimizations for edge infrastructures.

Abstract
INTRODUCTION Influenza A viruses cause global health concerns due to their high amino acid substitution rates. They are linked to yearly seasonal epidemics and occasional pandemics. This study focused on sequencing influenza A virus strains in Pakistan. MATERIALS AND METHODS We analyzed the genetic characteristics of influenza A(H1N1)pdm09 and A(H3N2) viruses circulating in Pakistan from January 2020 to January 2023. Whole genome sequences from influenza A (n = 126) virus isolates were amplified and sequenced by the Oxford Nanopore (MinION) platform. RESULTS The HA genes of influenza A(H1N1)pdm09 underwent amino acid substitutions at positions K54Q, A186T, Q189E, E224A, R259K, and K308R in sequenced samples. The HA genes of influenza A(H3N2) had amino acid substitutions at G53D, E83K, D104G, I140M, S205F, A212T, and K276R in the sequenced samples. Furthermore, the HA gene sequences of influenza A(H1N1)pdm09 in this study belonged to subclade 6B.1A.5a.2a. Similarly, the HA gene sequences of influenza A(H3N2) were classified under six subclades (3C.3a.1 and 3C.2a1b.2a [2, 2a.1, 2b, 2c, and 2a.3b]). Notably, amino acid substitutions in other gene segments of influenza A(H1N1)pdm09 and A(H3N2) were also found. CONCLUSION These findings indicate influenza A(H1N1)pdm09 and A(H3N2) viruses co-circulated during the 2020-2023 influenza season in Pakistan. Continued surveillance is crucial for real-time monitoring of possible high-virulence variation and their relevance to existing vaccine strains.

Abstract
A simple and inexpensive spray pyrolysis deposition (SPD) approach was used to produce TiO2 and Cr (2-8) at.%-doped TiO2 thin films. To explore the morphological features of the films, FE-SEM micrographs were used and found that 6 and 8 at.% TiO2:Cr films had fibrous patterns with diameters of 0.45 and 0.78 μm, respectively, while the remainder of the films were agglomerated particles. From X-ray diffraction investigation, it was found that the TiO2 thin films had an anatase crystal phase (tetragonal) up to 6 at.% Cr doping, while an anatase-rutile mixed crystalline phase was identified for 8 at.% Cr doping. The crystallite size of the pristine TiO2 film was 35 nm, while for TiO2:Cr films, it ranges from 35 to 46 nm. The Fizeau fringes technique was employed to measure the thickness of the TiO2 film and 165 nm was found for pristine TiO2 and 164-180 nm for TiO2:Cr films. UV-visible spectroscopy was used to study optical properties such as absorbance, refractive index, optical band gap, dielectric constant, and optical conductivity. As the Cr concentration increases, the optical band gap decreases from 3.40 eV to 2.70 eV. Using the four-point probe method, it was found that the resistivity changes with temperature and is also affected by the Cr content.

Abstract
Pesticide application has become a mandatory requirement of the modern agricultural system, resulting in the objectionable levels of pesticide residues in the treated food commodities and posing health threats to the consumers. This study aimed at optimization and validation of an analytical method which can be reliably applied for routine monitoring of the selected eighteen widely reported pesticides in tomato and eggplant. The principle of quick, easy, cheap, effective, rugged, and safe, i.e., QuEChERS, involving the acetate-buffered extraction followed by cleanup using the primary secondary amines (PSA) was employed. The analytical method was validated at three spiking levels (0.05, 0.01, 0.005 mg/kg) using gas chromatograph-micro electron capture detector (GC-µECD). Gas chromatograph-mass spectrometric detector (GC-MSD) was also used for confirmation and quantification using selective ion monitoring (SIM) mode. The method was applied on fresh samples of tomato (n = 33) and eggplant (n = 27) collected from local markets of Khyber Pakhtunkhwa, Pakistan, in the crop season 2020-2021. Twenty-five (76%) tomato samples and fifteen (56%) eggplant samples were found positive for one or more pesticides. Though the chronic and acute health risk assessments indicate that both of these vegetables are unlikely to pose any unacceptable health threat to their consumers, yet the risks from regular intake of pesticides-contaminated food commodities should be regularly addressed for possible protection of the public health and assurance of safe and consistent agro-trade, alike.

Abstract
Pterostilbene (PTS) is a naturally occurring phytoalexin. PTS displays limited water solubility, which consequently results in its diminished oral bioavailability. Therefore, a ternary inclusion complex (TIC) of PTS with β-cyclodextrin (βCD) in the presence of ternary substance Pluronic® F-127 (PLF) was prepared using microwave technology. The PTS-TIC was characterized by dissolution performance. Further, the prepared TIC was characterized by DSC, FTIR, NMR, XRD, and SEM analysis. Additionally, the antioxidant activity of PTS and PTS-TIC was also evaluated. Phase-solubility studies revealed that PTS's solubility in water was increased by 6.72 times when βCD/PLF was present. In comparison with PTS, prepared PTS-TIC produced a considerable improvement in PTS release. After 1 h, 74.03 ± 4.47% of PTS was released from PTS-TIC. Outcomes of DSC, FTIR, NMR, XRD, and SEM analysis revealed that the PTS was enclosed in the βCD cavity. In terms of antioxidant properties, the PTS-TIC formulation demonstrated superior activity compared to PTS, possibly attributed to the improved solubility of PTS resulting from the formation of TIC using microwave technology. It was concluded that microwave technology proved to be an extremely beneficial means of interacting PTS with βCD. In addition to increasing the solubility of PTS, the findings are also expected to improve its bioavailability by increasing its solubility. As a result, this study could provide insight into potential methods for enhancing the solubility of polyphenolic substances like PTS.

Abstract
Transition metal dichalcogenide (TMDC) nanotubes exhibit unique physical properties due to their nanotube structures. The development of techniques for synthesizing TMDC nanotubes with controlled structures is very important for their science and applications. However, structural control efforts have been made only for the homostructures of TMDC nanotubes and not for their heterostructures that provide an important platform for their two-dimensional counterparts. In this study, we synthesized heterostructures of TMDC nanotubes, MoS2/WS2 heteronanotubes, and demonstrated a technique for controlling features of their structures, such as diameters, layer numbers, and crystallinity. The diameter of the heteronanotubes could be tuned with inner nanotube templates and was reduced by using small-diameter WS2 nanotubes. The layer number and crystallinity of the MoS2 outer wall could be controlled by controlling their precursors and synthesis temperatures, resulting in the formation of high-crystallinity TMDC heteronanotubes with specific chirality. This study can expand the research of van der Waals heterostructures.

Dasatinib (DAS) is a narrow therapeutic index drug and novel oral multitarget inhibitor of tyrosine kinase and approved for the first-line therapy for chronic myelogenous leukemia (CML) and Philadelphia chromosome (Ph + ) acute lymphoblastic leukemia (ALL). DAS, a known potent substrate of cytochrome (CYP) 3A, P-glycoprotein (Pgp) and breast cancer resistance protein (BCRP) and is subject to auto-induction. The dietary supplementation of sinapic acid (SA) or concomitant use of SA containing herbs/foods may alter the pharmacokinetics as well as pharmacodynamics of DAS, that may probably lead to potential interactions. Protein expression in rat hepatic and intestinal tissues, as well as the in vivo pharmacokinetics of DAS and the roles of CYP3 A2 and drug transporters Pgp-MDR1 and BCPR/ABCG2, suggested a likely interaction mechanism. The single dose of DAS (25 mg/kg) was given orally to rats with or without SA pretreatment (20 mg/kg p.o. per day for 7 days, n = 6). The plasma concentration of DAS was estimated by using Ultra-High-Performance Liquid Chromatography Mass spectrometry (UHPLC-MS/MS). The in vivo pharmacokinetics and protein expression study demonstrate that SA pretreatment has potential to alter the DAS pharmacokinetics. The increase in Cmax, AUC and AUMC proposes increase in bioavailability and rate of absorption via modulation of CYP3 A2, PgP-MDR1 and BCPR/ABCG2 protein expression. Thus, the concomitant use of SA alone or with DAS may cause serious life-threatening drug interactions.

Abstract
Tungsten disulfide (WS2) nanotubes exhibit various unique properties depending on their structures, such as their diameter and wall number. The development of techniques to prepare WS2 nanotubes with the desired structure is crucial for understanding their basic properties. Notably, the synthesis and characterization of multi-walled WS2 nanotubes with small diameters are challenging. This study reports the synthesis and characterization of small-diameter WS2 nanotubes with an average inner diameter of 6 nm. The optical absorption and photoluminescence (PL) spectra of the as-prepared nanotubes indicate that a decrease in the nanotube diameter induces a red-shift in the PL, suggesting that the band gap narrowed due to a curvature effect, as suggested by theoretical calculations.

Abstract
Comprehension of chemical bonding and its intertwined relation with charge carriers and heat propagation through a crystal lattice is imperative to design compounds for thermoelectric energy conversion. Here, we report the synthesis of large single crystal of new p-type cubic AgSnSbTe3 which shows an innately ultra-low lattice thermal conductivity (κlat ) of 0.47-0.27 Wm-1 K-1 and a high electrical conductivity (1238 - 800 S cm-1 ) in the temperature range 294-723 K. We investigated the origin of the low κlat by analysing the nature of the chemical bonding and its crystal structure. The interaction between Sn(5 s)/Ag(4d) and Te(5p) orbitals was found to generate antibonding states just below the Fermi level in the electronic band structure, resulting in a softening of the lattice in AgSnSbTe3 . Furthermore, the compound exhibits metavalent bonding which provides highly polarizable bonds with a strong lattice anharmonicity while maintaining the superior electrical conductivity. The electronic band structure exhibits nearly degenerate valence-band maxima that help to achieve a high Seebeck coefficient throughout the measured temperature range and, as a result, the maximum thermoelectric figure of merit reaches to ≈1.2 at 661 K in pristine single crystal of AgSnSbTe3 .

Abstract
Sinapic acid (SA) is a bioactive phenolic acid; its diverse properties are its anti-inflammatory, antioxidant, anticancer, and antibacterial activities. The bioactive compound SA is poorly soluble in water. Our goal was to formulate SA-transethosomes using thin-film hydration. The prepared formulations were examined for various parameters. In addition, the optimized formulation was evaluated for surface morphology, in-vitro penetration studies across the Strat M®, and its antioxidant activity. The optimized formulation (F5) exhibited 74.36% entrapment efficacy. The vesicle size, zeta potential, and polydispersity index were found to be 111.67 nm, -7.253 mV, and 0.240, respectively. The surface morphology showed smooth and spherical vesicles of SA-transethosomes. In addition, the prepared SA-transethosomes exhibited enhanced antioxidant activity. The SA-transethosomes demonstrated considerably greater penetration across the Strat M® membrane during the study. The flux of SA and SA-transethosomes through the Strat M® membrane was 1.03 ± 0.07 µg/cm2/h and 2.93 ± 0.16 µg/cm2/h. The enhancement ratio of SA-transethosomes was 2.86 ± 0.35 compared to the control. The SA-transethosomes are flexible nano-sized vesicles and are able to penetrate the entrapped drug in a higher concentration. Hence, it was concluded that SA-transethosome-based approaches have the potential to be useful for accentuating the penetrability of SA across the skin.

Abstract
This study was conducted to investigate the diversity and antimicrobial resistance profiling of Staphylococcus species causing sub-clinical mastitis (SCM) in dairy herds in Bangladesh as well as putative risk factors associated with the infections. Individual quarter milk samples were collected from a total of 284 lactating cows from 30 dairy farms were screened by means of California mastitis test; 178 (62.7%) of them had at least of quarter affected by SCM. After conventional microbiological isolation procedures, PCR tests were used for Staphylococcus species identification and detection of antimicrobial resistance and virulence genes. S. chromogenes (65.7%) was the most predominant species followed by, S. epidermidis (20.2%), S. haemolyticus (19.1%), S. aureus (15.7%), and S. sciuri (5.6%). High levels of antimicrobial resistance to ampicillin and amoxicillin/clavulanic acid were observed in S. aureus (82.1% and 75%) and S. sciuri (80% and 70%), while resistance to cefepime was markedly higher in S. chromogenes (95.7%), S. haemolyticus (94.1%), and S. epidermidis (97.2%). Multidrug resistance isolates were identified in all five species. The mecA gene was detected in S. aureus (32.1%) and S. chromogenes (5.98%). In addition, 20% S. sciuri and 17.7% S. haemolyticus carried the cytotoxin (pvl) gene, while 14.3% S. aureus harbored the toxic shock syndrome toxin (tst) gene. Multivariable logistic regression analysis identified "Old aged" (OR [CI]: 3.5 [1-12.4]); "Early stage of lactation" (OR [CI]: 3.4 [1.2-9.7]) and, "Firm udder condition" (OR [CI]: 4.2 [1.2-14.6]) as risk factors associated with SCM caused by S. aureus, S. chromogenes, and S. haemolyticus, respectively. Moreover, "Use of antimicrobials" (OR [CI]: 10.4 [3.4-32.1] and "History of previous clinical mastitis" (OR [CI]: 4.9 [1.2-19.7] for the carriage of methicillin-resistant Staphylococcus spp.

Abstract
The objective of this study was to investigate the effects of cinnamon on the pharmacodynamic (PD) & pharmacokinetic (PK) of amlodipine in hypertensive rats. The hypertensive control group of Wistar rats received L-NAME (40 mg/kg, daily, orally) only. The cinnamon group of rats was treated with cinnamon (200 mg/kg, daily, orally) along with L-NAME. Following 14 days treatment period, blood pressures of rats were monitored at designated intervals over 24 h utilizing a tail-cuff system for measuring blood pressure. To assess the oral PK; amlodipine was administered as a single oral dose of 1 mg/kg to rats and blood samples were collected at specified intervals over 24 h and analysed by UPLC-LC MS/MS. Synergistic decreased in rat's blood pressure was observed in presence of cinnamon + amlodipine. Simultaneous administration of cinnamon ameliorates the Cmax and AUC0-t of amlodipine, the Cmax and AUC0-t was 11.04 ± 1.01 ng/ml and 113.76 ± 5.62 ng h/ml for the cinnamon + amlodipine group as compared to 4.12 ± 0.49 ng/ml and 48.59 ± 4.28 ng h/ml for the amlodipine alone group. The study demonstrates that the use of cinnamon considerably decreases the blood pressure levels and enhances the PK parameters of amlodipine in hypertensive rats.

Abstract
Diabetes treatment requires focused administration with quality systemic circulation to determine the optimal therapeutic window. Intestinal distribution through oral administration with nanoformulation provides several benefits. Therefore, the purpose of this study is to create plumbagin enclosed within niosomes using the quality by design (QbD) strategy for efficient penetration and increased bioavailability. The formulation and optimization of plumbagin-loaded niosomes (P-Ns-Opt) involved the use of a Box-Behnken Design. The particle size (PDI) and entrapment efficiency of the optimized P-Ns-Opt were 133.6 nm, 0.150, and 75.6%, respectively. TEM, DSC, and FTIR were used to analyze the morphology and compatibility of the optimized P-Ns-Opt. Studies conducted in vitro revealed a controlled release system. P-Ns-Opt's antioxidant activity, α-amylase, and α-glucosidase were evaluated, and the results revealed a dose-dependent efficacy with 60.68 ± 0.02%,90.69 ± 2.9%, and 88.43 ± 0.89%, respectively. In summary, the created P-Ns-Opt demonstrate remarkable potential for antidiabetic activity by inhibiting oxygen radicals, α-amylase, and α-glucosidase enzymes and are, therefore, a promising drug delivery nanocarrier in the management and treatment of diabetes.

Abstract
Mycobacterium tuberculosis (Mtb) defends host-mediated killing by repressing the autophagolysosome machinery. For the first time, we report NCoR1 co-repressor as a crucial host factor, controlling Mtb growth in myeloid cells by regulating both autophagosome maturation and lysosome biogenesis. We found that the dynamic expression of NCoR1 is compromised in human peripheral blood mononuclear cells (PBMCs) during active Mtb infection, which is rescued upon prolonged anti-mycobacterial therapy. In addition, a loss of function in myeloid-specific NCoR1 considerably exacerbates the growth of M. tuberculosis in vitro in THP1 differentiated macrophages, ex vivo in bone marrow-derived macrophages (BMDMs), and in vivo in NCoR1MyeKO mice. We showed that NCoR1 depletion controls the AMPK-mTOR-TFEB signalling axis by fine-tuning cellular adenosine triphosphate (ATP) homeostasis, which in turn changes the expression of proteins involved in autophagy and lysosomal biogenesis. Moreover, we also showed that the treatment of NCoR1 depleted cells by Rapamycin, Antimycin-A, or Metformin rescued the TFEB activity and LC3 levels, resulting in enhanced Mtb clearance. Similarly, expressing NCoR1 exogenously rescued the AMPK-mTOR-TFEB signalling axis and Mtb killing. Overall, our data revealed a central role of NCoR1 in Mtb pathogenesis in myeloid cells.

Abstract
Introduction Supraspinatus muscle atrophy is commonly associated with shoulder disease, but the effect of ageing on atrophy is not well understood. It was the aim of this study to investigate this effect using MRI scans in older patients. Methods and materials A retrospective review of MRI scans in patients aged >70 years was performed between Jan 2016-Dec 2018.Both normal and abnormal scans were included in the analysis which included quantifying muscle atrophy of the supraspinatus using Thomazeu's occupation ratio. Results There were 39 normal shoulder MRI scans with a mean age of 75 years (range: 70-88) and 163 abnormal scans with a mean age of 77 years (range: 70-93). The mean supraspinatus occupation ratio for normal MRI scans was 0.57 (range: 0.33-0.86) and abnormal scans 0.35 (range: 0.17-0.90). Occupation ratio was maintained with advancing until the age of 85 years before undergoing a significant declin following this. Conclusion This study has shown that the occupation ratio is significantly reduced with shoulder disease, but normal shoulders do not undergo significant atrophy of supraspinatus tendon with increasing age. An occupation ratio of <0.32 is unlikely to occur in normal shoulders and this awareness may be useful when planning shoulder surgery, specifically shoulder arthroplasty.

Abstract
INTRODUCTION AND IMPORTANCE Secretory carcinoma (SC) is an uncommon salivary gland neoplasm of the oral cavity that microscopically may mimic acinic cell carcinoma (ACC) and mucoepidermoid carcinoma (MEC). Secretory carcinoma (SC) of the salivary gland has been recently added in fourth edition of the head and neck world health organization. Most of these tumors are located on the parotid gland with very few cases reported in the minor salivary glands of the buccal mucosa. This work has been reported in line with the SCARE criteria. PRESENTATION OF CASE A 42 years old hypertensive male, shop keeper by occupation, with no prior addiction history, no dental extraction or trauma, presented with complaint of nodular lesion on left buccal mucosa for five years. On Clinical examination, adequate mouth opening, dentulous patient with 2.4 × 2 cm well circumscribed, nodular, non-tender, benign looking lesion was observed on left buccal mucosa near upper alveolus. Overlying mucosa appeared normal with no clinically palpable cervical lymphadenopathy. Histopathology revealed salivary gland neoplasm favoring secretory carcinoma. MRI scan showed lobulated enhancing nodular lesion arising from left buccal mucosa of size 2.3 ∗ 1.3 ∗ 1.7 cm, close to left superior alveolus without involving any cortical areas of marrow infiltration, with bilateral symmetrical level IIa reactive cervical nodes. Wide local excision and ipsilateral selective neck dissection [level 1, 2, 3] was done. Post-operative period was smooth with no complain of paresthesia observed. The final histopathology report showed secretory carcinoma. Two out of six lymph nodes from level I were positive for metastatic carcinoma with no extra nodal extension. Final stage of the tumor was pT1N2bMx. Patient underwent post-operative adjuvant radiotherapy for period of 6 weeks, received total 30 fractions and total dose of 6000 centigray. CLINICAL DISCUSSION SC behaved clinically an indolent being painless and having long duration of symptoms with normal overlying mucosa. But histopathologically there was cervical node metastasis. That changed final staging and added adjuvant treatment for this patient. The discrepancy in clinical and pathological diagnosis might be due to the indolent clinical behavior of SC arising in the minor salivary gland of buccal mucosa. In the present case, the absence of zymogen granules and presence of microcytic pattern with eosinophilic cytoplasm and eosinophilic secretory material were suggestive of SC. CONCLUSION This case report represents a rare case of SC of minor salivary glands of buccal mucosa, which was indolent as per clinical presentation but on final histopathological report it had cervical nodal metastasis that changed the final stage of the disease, for which adjuvant radiotherapy was needed. Although Secretory carcinomas are generally considered having a favorable prognosis and are regarded as low- grade carcinomas with limited number of recurrence and cervical nodal metastasis, but sometimes they do metastasize to cervical nodes for which accurate and timely intervention in the form of neck dissection may be performed to establish final staging and start additional treatment modality if required for better outcome of the disease.

Abstract
Abstract
Persistence in a dormant state of residual tumor cells can occur following extended periods of clinical remission which may last decades. The disseminated tumor cells in distant organ sites eventually gain context dependent metastasis advantage during tumor progression. The mechanisms for dormancy induction or reactivation remain unclear. We found that the abrogation of myeloid TGF-β signaling induced tumor dormancy in breast cancer metastasis models. When given extended time, the TGFβRIImyeKO mice eventually developed similar number of metastatic nodules to that of control mice. We further validated our finding using an inducible system where reintroduction of TβRII diminished the tumor dormancy induction. RNAseq of dormant vs proliferative tumor cells identify 504 differential expressed genes, including those involving cell cycle arrest, IFNg response, MTOR signaling as well as MYC targeted genes. Immune cell profiling showed differential immune composition in micro and macro-tumor microenvironment between WT and TβRIImyeKO lung tissues. Of great interest, abrogation of myeloid specific TGF-β signaling increased the number of CD103+DCs that displayed elevated TNFa production, which in turn increased IFNg+ production in T cells leading to improved innate
and adaptive immunity. Importantly, depletion of CD103 DCs in tumor-bearing TβRIImyeKO mice diminished the dormancy phenotype, which was not observed for the pDC depletion in the WT control mice. These data demonstrate that abrogation of myeloid specific TGF-β signaling improved the immune microenvironment, which induced tumor dormancy. Our data provide mechanistic insight and resources to understand the tumor dormancy.

Abstract
The objective of the study was to determine the diagnostic accuracy of Mentzer Index in children with hypochromic microcytic anemia by taking serum ferritin levels as a gold standard. This cross-sectional study was conducted in the Department of Pediatric Medicine, Liaquat National Hospital Karachi, from 1st January to 30th June 2022. Children age 1 to 5 years and both genders were included in this study. Children who have had a history of blood transfusion in the past 3 months or Thalassemia or blood disorders, chronic liver disease or kidney diseases, and children with malignancy and congenital abnormalities were excluded. Eligible children were enrolled after taking written informed consent. Complete blood count (CBC) and serum ferritin were sent to the laboratory. Sensitivity, specificity, diagnostic accuracy, and likelihood ratio were calculated taking serum ferritin levels as a gold standard. A total of 347 subjects were enrolled. The median age was 26 (IQR-18) months and 42.9% were males. The most common symptom was fatigue 40.9%. The sensitivity of the Mentzer index was 80.7% while the specificity was 77.7%. Similarly, the positive predictive value (PPV) was 56.8% while the negative predictive value (NPV) was 91.6%. Finally, the accuracy of the Mentzer index in determining iron deficiency anemia was 78.4%. Diagnostic accuracy was 78.4% and the likelihood ratio was 3.6. Mentzer index is a valuable tool in the early detection of IDA in children. It has got high sensitivity, specificity diagnostic accuracy, and likelihood ratio.

Abstract
Dasatinib (DAS), a narrow-therapeutic index drug, Bcr-Abl, and Src family kinases multitarget inhibitor have been approved for chronic myelogenous leukemia (CML) and Ph-positive acute lymphocytic leukemia (Ph+ ALL). Apigenin (APG) has a long history of human usage in food, herbs, health supplements, and traditional medicine, and it poses low risk of damage. The concomitant use of APG containing herbs/foods and traditional medicine may alter the pharmacokinetics of DAS, that probably lead to possible herb-drug interactions. The pharmacokinetic interaction of APG pretreatment with DAS in rat plasma following single and co-oral dosing was successfully deliberated using the UPLC-MS/MS method. The in vivo pharmacokinetics and protein expression of CYP3A2, Pgp-MDR1, and BCPR/ABCG2 demonstrate that APG pretreatment has potential to drastically changed the DAS pharmacokinetics where escalation in the Cmax, AUC(0-t), AUMC(0-inf_obs), T1/2, Tmax, and MRT and reduction in Kel, Vd, and Cl significantly in rats pretreated with APG 40 mg/kg, thus escalating systemic bioavailability and increasing the rate of absorption via modulation of CYP3A2, Pgp-MDR1, and BCPR/ABCG2 protein expression. Therefore, the concomitant consumption of APG containing food or traditional herb with DAS may cause serious life-threatening drug interactions and more systematic clinical study on herb-drug interactions is required, as well as adequate regulation in herbal safety and efficacy.

Abstract
INTRODUCTION Innominate artery aneurysm (IAA) is an extremely rare fatal condition with an overall prevalence of less than 3 % of all supra-aortic artery aneurysms. These infrequent lesions usually present as an emergency and require challenging surgical procedures. CASE PRESENTATION We report an interesting case of mycotic IAA in a 25 years old male patient. He was a known intravenous drug abuser having mycotic aneurysm arising from brachiocephalic artery with eccentric thrombus causing adjacent mass effect over the trachea. He underwent successful emergent surgical management of aneurysm with autologous vein graft using superficial femoral vein. Unfortunately, he died due to massive upper gastrointestinal bleeding leading to multi-organ failure after a prolonged post-operative course. CLINICAL DISCUSSION Mycotic aneurysms of the IA are extremely rare with an overall incidence of 1-2.7 % cases of all IAA. Presentation of the IAA can be quite variable from asymptomatic to symptoms exhibiting mass effect over surrounding structures. Rupture of IAA can be fatal and can occur if not treated promptly. There are no current recommendations or guidelines for treatment and interventions in IAA. Surgical management involves complete excision of the aneurysm and then revascularization. CONCLUSION Infected Innominate artery aneurysm is a rare surgical entity requiring early diagnosis, detailed investigation and prompt surgical management involving multidisciplinary team approach. Our case describes a relatively innovative approach to this scarce condition.

Abstract
In this study, Machine learning (ML) models integrated with genetic algorithm (GA) and particle swarm optimization (PSO) have been developed to predict, evaluate, and analyze biochar yield using biomass properties and process operating conditions. Comparative study of different ML algorithms integrated with GA and PSO were performed to improve the ML models architecture and parameters selection. The results proposed that Ensembled Learning Tree (ELT-PSO) model outperformed all other models and is favored for biochar yield prediction (R2 = 0.99, RMSE = 2.33). The partial dependence plots (PDPs) analysis shows the potential effects of each influencing parameter impact on the biochar yield and as well as shows that how these factors will interact during the pyrolysis process. A user-friendly software was developed based on the ELT-PSO model to avoid extensive and expensive experimentations without requiring considerable ML understanding. Difference recorded by GUI was less than 2% with experimental yield.

Abstract
AIM To explore the potential effect of locally applied 1% Curcumin on myeloperoxidase (MPO) enzymatic activity in gingival crevicular fluid (GCF) and on the periodontal status during the initial phase of orthodontic tooth movement. SETTINGS AND DESIGN Forty patients (26 females and 14 males) aged 12-25 years who required fixed orthodontic treatment were randomly divided into two equal groups. The control and test groups were similar in the various baseline parameters, including standard oral hygiene protocol. Moreover, 1% Curcumin gel was applied around mandibular anterior teeth in the test group twice daily, from three days before to 14 days after the placement of archwires. MPO activity and periodontal status were recorded at five different time points; before placement of archwire (baseline), immediately after placement of archwire, 2 hours, 7 days, and 14 days later. STATISTICAL ANALYSIS USED The data were analyzed using the paired t-test for intra-group differences and the unpaired t-test for intergroup differences at five different time points. Statistical significance in the intragroup and intergroup difference of Plaque and Gingival index was calculated using the unpaired t-test. RESULTS Maximum MPO enzymatic activity in GCF was observed two hours after the placement of the archwire. MPO activity decreased slightly on the seventh day, but values were still elevated as compared to baseline. However, MPO activity came back to the values similar to baseline on day 14 in the control group and significantly lower than the baseline in the test group. The inter-group differences in clinical periodontal parameters were non-significant. CONCLUSIONS The locally applied 1% Curcumin gel appears to decrease the MPO activity in GCF on the 14th day after placement of the archwires. However, clinical periodontal status in the initial phase of tooth movement is unaffected by curcumin if patients adhere to good plaque control.

Abstract
Dendritic cell (DC) fine-tunes inflammatory versus tolerogenic responses to protect from immune-pathology. However, the role of co-regulators in maintaining this balance is unexplored. NCoR1-mediated repression of DC immune-tolerance has been recently reported. Here we found that depletion of NCoR1 paralog SMRT (NCoR2) enhanced cDC1 activation and expression of IL-6, IL-12 and IL-23 while concomitantly decreasing IL-10 expression/secretion. Consequently, co-cultured CD4+ and CD8+ T-cells depicted enhanced Th1/Th17 frequency and cytotoxicity, respectively. Comparative genomic and transcriptomic analysis demonstrated differential regulation of IL-10 by SMRT and NCoR1. SMRT depletion represses mTOR-STAT3-IL10 signaling in cDC1 by down-regulating NR4A1. Besides, Nfkbia and Socs3 were down-regulated in Ncor2 (Smrt) depleted cDC1, supporting increased production of inflammatory cytokines. Moreover, studies in mice showed, adoptive transfer of SMRT depleted cDC1 in OVA-DTH induced footpad inflammation led to increased Th1/Th17 and reduced tumor burden after B16 melanoma injection by enhancing oncolytic CD8+ T-cell frequency, respectively. We also depicted decreased Ncor2 expression in Rheumatoid Arthritis, a Th1/Th17 disease.

Abstract
Background Hypolipidemic agents have been shown to be helpful in the primary and secondary prevention of cardiovascular disease. Most often, statins are prescribed to treat hyperlipidemia. There are a number of statins available in the market today, but atorvastatin is the most widely prescribed. It is essential that the drugs should have the appropriate amount of active pharmaceutical ingredient and meet the necessary physical properties. The main purpose of the study was to evaluate the quality of different marketed brands of atorvastatin calcium tablets available in Saudi Arabia. Methods In this study, innovator product coded as (AS-1) and five generics brands (coded as AS-2 to AS-6) of atorvastatin tablets 20 mg available in Saudi Arabia were evaluated for in vitro dissolution test, weight variations, friability and hardness tests. The analysis of drug was carried out by “high-performance liquid chromatography” (HPLC) method using C18 column (4.6 × 150 mm, 5 μm). The mobile phase was consisted of acetonitrile and HPLC water (pH 2.1, adjusted with orthophosphoric acid) in ratio of 52:48 v/v, the flow rate was 1.0 ml/min. Atorvastatin was detected at a wavelength of 254 nm. Results According to the results of the dissolution study, the investigated products released more than 90% of atorvastatin in 15 min. Within 60 min, the brands AS-1, AS-3, AS-5, and AS-6 depicted nearly 100% atorvastatin release, while the brand AS-2 displayed 91.69% drug release. According to our findings, the investigated atorvastatin innovator (AS-1) and generic brands such as AS-2 to AS-6 were of good pharmaceutical quality. Conclusions All generic brands of atorvastatin tablets available in the Saudi Arabian market met the pharmacopoeia's consistency checks such as weight variation, friability, hardness and in vitro dissolution. Hence, focusing on their in vitro release properties, it was determined that these brands could be used interchangeably.

Abstract
BACKGROUND Numerous herbs are reported to have anti-hyperglycemic activity and are frequently used in combination with prescription drugs to lower the blood glucose levels in diabetic patients, without proper knowledge about the possibility of herb-drug interaction. OBJECTIVES To investigate the effect of cumin and garden cress on pharmacokinetics (PK) and pharmacodynamics (PD) of gliclazide (GLZ) in nicotinamide-streptozotocin diabetic model. METHODS Diabetic animals of groups II-IV were treated with GLZ, cumin, 'cumin + GLZ', garden cress and 'garden cress + GLZ'. Herb's treatments were given for two weeks, and GLZ was administered in a single dose. Blood glucose levels (BGLs) were measured at pre-determined time points. Plasma samples of pharmacokinetic study were analyzed using UPLC-MS/MS. GLZ fragment at m/z 324.1>127 was monitored. RESULTS Cumin and garden cress have shown 15.3% and 15.9% reduction in mean BGL (1-24h) (p-value < 0.001), respectively. GLZ reduced mean BGL by 30.0%, which was significantly better than cumin and garden cress (pvalue <0.05). Concurrently administered "garden cress + GLZ" demonstrated the highest reduction in mean BGL (by 40.46%) and showed a prolonged effect. There was no significant advantage of simultaneously administered 'cumin + GLZ'. Cumin did not affect PK of GLZ. Garden cress has significantly enhanced AUC0-t (by 69.8%, pvalue 0.0013), but other PK parameters Cmax, Tmax, and Kel were close to the control group. CONCLUSION PK/PD-based herb-drug interaction was observed. Concurrently administered garden cress + GLZ showed improved antidiabetic effect and has enhanced GLZ bioavailability.

Abstract
Tight control of gene regulation in dendritic cells (DCs) is important to mount pathogen specific immune responses. Apart from transcription factor binding, dynamic regulation of enhancer activity through global transcriptional repressors like Nuclear Receptor Co-repressor 1 (NCoR1) plays a major role in fine-tuning of DC responses. However, how NCoR1 regulates enhancer activity and gene expression in individual or multiple Toll-like receptor (TLR) activation in DCs is largely unknown. In this study, we did a comprehensive epigenomic analysis of murine conventional type-I DCs (cDC1) across different TLR ligation conditions. We profiled gene expression changes along with H3K27ac active enhancers and NCoR1 binding in the TLR9, TLR3 and combined TLR9 + TLR3 activated cDC1. We observed spatio-temporal activity of TLR9 and TLR3 specific enhancers regulating signal specific target genes. Interestingly, we found that NCoR1 differentially controls the TLR9 and TLR3-specific responses. NCoR1 depletion specifically enhanced TLR9 responses as evident from increased enhancer activity as well as TLR9-specific gene expression, whereas TLR3-mediated antiviral response genes were negatively regulated. We validated that NCoR1 KD cDC1 showed significantly decreased TLR3 specific antiviral responses through decreased IRF3 activation. In addition, decreased IRF3 binding was observed at selected ISGs leading to their decreased expression upon NCoR1 depletion. Consequently, the NCoR1 depleted cDC1 showed reduced Sendai Virus (SeV) clearance and cytotoxic potential of CD8+ T cells upon TLR3 activation. NCoR1 directly controls the majority of these TLR specific enhancer activity and the gene expression. Overall, for the first time, we revealed NCoR1 mediates transcriptional control towards TLR9 as compared to TLR3 in cDC1.

Abstract
Background and Aim: Bluetongue (BT) is a non-contagious, infectious disease of wild and domestic ruminant animals caused by the BT virus (BTV). Bangladesh having a border with a BTV-endemic country, India and a substantial number of susceptible animals. Therefore, this study aimed to estimate BTV seroprevalence and potential risk factors. Materials and Methods: We collected 150 serum samples from indigenous sheep from Chattogram, Bangladesh. We screened the serum samples using a competitive enzyme-linked immunosorbent assay for detecting BTV-specific immunoglobulin. Results: We detected antibodies against BTV in 39.3% (59/150; 95% confidence interval: 31.5–47.6) of all sampled sheep. Factors like sampling site, sheep rearing location, rearing sheep with other farm species, and body condition score had a significant (p < 0.05) influence on the seroprevalence of BTV. Conclusion: The findings show that indigenous sheep have a higher BTV seroprevalence, necessitating sustained surveillance for early diagnosis and a better understanding of virus epidemiology in Bangladesh.

Abstract
Introduction Indications for surgical management of displaced humeral shaft fractures are not clearly established, leading to variations in practice. The aim of this study was to determine the scale of these variations in the UK practice to help design a future national trial. Methods An online survey was sent to all surgeon members of British Elbow and Shoulder Society to help define humeral shaft fractures, fracture displacement as well as indications for operative and non-operative management. Patient and injury related factors considered important when managing humeral shaft fractures were investigated. Results The survey achieved a response rate of 32% (104/327). There was a lack of consensus on definitions for humeral shaft fractures and fracture displacement. A functional brace was the most common form of non-operative treatment (63%). Majority immobilise humeral shaft fractures for 4-8 weeks or until callus are visible (62%) with a similar number considering operative treatment if adequate signs of healing are not present at around 12-16 weeks. Around half of our respondents exclusively use plates with variations in preference of approach and a minority (2%) exclusively use intra-medullary nails. Conclusion The significant variation in management of displaced humeral shaft fractures in the UK suggests a clear need to evaluate clinical and cost effectiveness through a multi-centre randomised trial.

Abstract
The goal of this work was to improve the aqueous solubility and dissolution rate of eprosartan mesylate by preparing inclusion complex of drug with β-cyclodextrin (β-CD) by microwave technique. In order to determine the solubility of eprosartan, phase solubility was determined and dissolution study was also conducted. Further, analytical techniques for instance, particle size distribution, differential scanning calorimetry, powder X-ray diffraction, scanning electron microscopy, Fourier-transform infrared spectroscopy, and nuclear magnetic resonance spectroscopy were used for the characterization of inclusion complex. In addition, the binding pattern of eprosartan with the β-CD was investigated by molecular modeling study. Phase solubility study revealed that approximately 4.48 folds improvement in the solubility of drug was noted with β-CD (10 mM). The estimated stability constant (Kc) values for eprosartan:β-CD binary mixture was found to be 280.78 M–1. The prepared inclusion complex of drug with β-CD presented better drug release profile (62.96 ± 2.01% in 1 h) as compared to their physical mixture (41.41 ± 1.77% in 1 h) or drug per se (29.97 ± 3.13%). The inclusion complex demonstrated different features and properties from pure drug, and we inferred that this could be due to the inclusion of drug into cyclodextrin cavity that confirmed by different analytical method. Molecular modeling study demonstrated a good affinity of eprosartan to entangle to β-CD. The outcomes have shown that guest molecule has many significant interactions with the host molecule. These observations are very interesting and may be a valuable approach to improve the solubility and in turn the bioavailability of eprosartan.

Abstract
Diabetic nephropathy (DN) is a significant source of end-stage renal illness all over the world in both developed and developing countries. The aim of the study was to optimize rubiadin-loaded niosomes (RLN) using Box-Behnken design for the management of streptozotocin-nicotinamide (STZ-NA)-induced DN in Wistar rats. The RLN were formulated by a "thin-layer hydration technique." The optimization of RLN was done by Box-Behnken design; the independent variables were cholesterol (CHOL), Span 80, and methanol, while the dependent factors were the vesicle size, zeta potential, and entrapment efficiency. The optimized formulation was characterized for various biochemical parameters including anti-diabetic activity in Wistar rats. The optimized RLN presented vesicle size of 238 nm, zeta potential -68 mV, and entrapment efficiency 85%. A noteworthy decreased in blood glucose level was detected in STZ-NA-induced DN rats when orally treated with RLN (100 mg/kg/week and 200 mg/kg/week). Oral administration of RLN formulation considerably decreased the levels of urea, uric acid, and creatinine in DN rats. In addition, treatment of DN rats with RLN formulation considerably improves the level of TBARS, GSH, SOD, and CAT. The lipid profile of DN rats was also improved on treatment with RLN formulation. This study revealed that the prepared RLN formulation was successfully optimized by Box-Behnken design and found to be useful for the management of STZ-NA-induced DN in Wistar rats.

Abstract
The novel coronavirus (COVID-2019) has spread very rapidly all over the globe, causing an outbreak of acute infectious pneumonia. This pandemic brought not only the risk of death but also psychological pressure on people and remarkably on college students. To assess the psychological impact of COVID-19 on college students. A web-based cross-sectional study was conducted on college students studying diploma, graduation, and post-graduation irrespective of their gender was included in the study. The data was collected through online mode by providing links to fill google form. The survey tool was disseminated in various messenger groups and social media networks. The survey tool comprises demographics, COVID-19 stressors, generalized anxiety disorder scale (GAD 7), and patient health questionnaire (PHQ 9) scale. Chi-square was used to find the association between demographic characters with anxiety and depression. 443 students participated in this web-based survey. Among all participants, 44.25% were normal range, 31.38% are mild anxiety, 18.97% were moderate anxiety, and 5.42% were severe anxiety. Results also indicated that there were 37.25% participants were in normal range, about 27% were mild depression, 22.13% moderate depression, 7.45% moderately severe depression and 6.1% severe depression. All the variables other than gender, place of residence, and steady family income were significantly associated with anxiety, whereas gender and place of residence variables were not significantly associated with depression. To conclude, the mental health of college students was significantly affected by the pandemic. More help and support from society, families and colleges would be supportive to them. It is suggested that the government and colleges should collaborate to resolve this problem by providing high-quality, timely crisis oriented psychological services to college students.

Abstract
BACKGROUND These days, poly pharmacy is very common for the treatment of multiple diseases and majority of drugs were metabolized with CYP 450 enzymes. Diabetes mellitus is such a disorder, which requires continuous therapy for the control of blood glucose concentration. Depression was quite common in diabetic patients. Therefore, multiple drugs required to treat diabetes mellitus and depression. Simultaneous administration of these drugs leads to drug interaction. Pioglitazone and trazodone metabolized by CYP3A4 enzymes which may lead to potential drug interaction. OBJECTIVES This study aimed to find the influence of trazodone on the pharmacokinetics & pharmacodynamics of pioglitazone in normal & diabetic rats, also on rabbits and subsequently effectiveness and safety of the combination was evaluated. METHODS AND MATERIAL Blood glucose concentration was determined by Glucose oxidase/peroxidase method in normal and diabetic rats. Diabetes was induced with Streptozotocin at a dose of 55 mg/kg body weight. Serum pioglitazone concentration was estimated by high performance liquid chromatography method for pharmacokinetic data. The values were expressed as Mean ± Standard Error Mean (SEM), GraphPad Prism 3.0 (San Diego, California, USA) software was used to express the data. Student's paired 't' test was used to determine the significance. RESULTS Pioglitazone produces hypoglycaemia in normal rats with a maximum decrease of 36.78 % ± 0.81 at 3 hours interval and anti-hyperglycaemic activity in diabetic rats with maximum reduction of 45.13 % ± 1.52 at 2 hours interval. Trazodone altered the pharmacokinetics of pioglitazone and improved the pioglitazone hypoglycaemic effect. CONCLUSION Trazodone apparently produced pharmacokinetic interaction with pioglitazone which might be by attenuating the metabolism of pioglitazone. Therefore, care should be taken in simultaneous therapy with pioglitazone and trazodone.

Abstract
1. Effects of Lepidium sativum and Curcuma longa were investigated on pharmacokinetics and pharmacodynamics of antihypertensive drug (amlodipine).2. Hypertensive rats were treated with amlodipine, Lepidium sativum, Lepidium sativum + amlodipine, Curcuma longa, and Curcuma longa + amlodipine; and their blood pressures were measured. Amlodipine in plasma samples was analysed using UPLC-TQD. Product ions of amlodipine were monitored at m/z 409.18 > 238 and 409.18 > 294; and of nitrendipine at m/z 361.16 > 315.1 and 361.16 > 329.10.3. Lepidium sativum + amlodipine treatment showed highest reduction in systolic blood pressure (SBP). Mean anti-hypertensive effect of Lepidium sativum and Curcuma longa was similar to amlodipine. Mean SBPs (1-24 h) of amlodipine, Lepidium sativum, Lepidium sativum + amlodipine, Curcuma longa, and Curcuma longa + amlodipine treated animals were found as 149.5 ± 2.4 mmHg, 151.6 ± 1.09 mmHg, and 141.8 ± 2.5 mmHg, 154.9 ± 2.2 mmHg and 144.4 ± 2.6 mmHg (p-values ≪0.05); respectively. Lepidium sativum and Curcuma longa significantly increased amlodipine Cmax by 83% (p-value 0.018) and 53% (p-value 0.035); and AUC0-t by 48% (p-value >0.05) and 56% (p-value 0.033); respectively.4. Results of pharmacokinetic and pharmacodynamic studies are in agreement. Lepidium sativum and Curcuma longa augment antihypertensive effect of amlodipine, which is also supported by pharmacokinetic observations.

Abstract
Chikungunya virus (CHIKV) is considered a public health problem due to its rapid spread and high morbidity. In 2016-2017 an outbreak of CHIKV was occurred in Pakistan but the data regarding the genomic diversity of CHIKV was not reported. Hence, the current study aimed to determine the genetic diversity of CHIKVs in Pakistan. A cross sectional study was carried out using sera of infected CHIKV patients (n = 1549) during the outbreak in Pakistan (2016-2018). Nucleotide sequencing of non-structural genes of CHIKV from eight isolates were performed followed by phylogenetic analysis using Bayesian method. Phylogenetic analysis suggested that the Pakistani CHIKV strains belonged to Indian Ocean Lineage (IOL) of genotype ECSA and C1.3a clade. Furthermore, the Pakistani isolates showed several key mutations (nsP2-H130Y, nsP2-E145D, nsP4-S55N and nsP4- R85G) corresponding to mutations reported in 2016 Indian strains of CHIKV. The molecular analysis revealed high evolutionary potential of CHIKV strains as well as better understanding of enhanced virulence and pathogenesis of this outbreak. The study highlights the need to continue surveillance in order to understand viral diversity over time and to devise preventive measures to limit diseases transmission in the region.

Abstract
Background The emergence of methicillin‐resistant Staphylococcus aureus (MRSA) and methicillin‐resistant Staphylococcus pseudintermedius (MRSP) have a significant health impact on people with direct or supportive occupations in veterinary medicine including veterinarians, animal handlers, laboratory personnel and pet owners. Objectives This cross‐sectional survey was conducted to determine the prevalence of and risk factors for S. aureus, S. pseudintermedius, MRSA and MRSP in dogs in Bangladesh. Methods A total of 358 swab samples were collected from different body sites of 150 dogs attending a university teaching veterinary hospital between January and June 2018. Standard bacteriological procedures were followed to isolate Staphylococcus, and identification was confirmed to the species level by PCR to detect the nuc gene. MRSA and MRSP were confirmed by the presence of the mecA gene. Results The prevalence of coagulase‐positive S. aureus and S. pseudintermedius in dogs were 16% and 45.3%, respectively. S. aureus and S. pseudintermedius isolates displayed the highest resistance against nalidixic acid (95.2% and 91%, respectively) and erythromycin (89.3% and 84.7%, respectively). Notably, all the staphylococcal isolates showed resistance to ≥3 antimicrobial classes. The prevalence of MRSA and MRSP in dogs was 8.7% and 6%, respectively. Multivariable logistic regression analysis identified the following variables as risk factors for MRSA colonisation in dogs: dogs with dermatitis (odds ratio [OR], 12.24, 95% CI: 3.12–57.33; p < 0.001) and history of antibiotic use (OR 8.73, 95% CI: 2.23–43.10; p < 0.001). Presence of otitis (OR 14.22; 95% CI: 1.64–103.58; p = 0.008) and oral lesions (OR 9.48, 95% CI: 1.14–64.82; p = 0.002) were identified as the significant risk factors for the carriage of MRSP. Conclusions The circulation of multidrug‐resistant S. aureus and S. pseudintermedius is a serious concern to dogs and humans. To our knowledge, this is the first report of S. pseudintermedius and MRSP affecting dogs in Bangladesh.

Abstract
The response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is largely impacted by the level of virus exposure and status of the host immunity. The nature of protection shown by direct asymptomatic contacts of coronavirus disease 2019 (COVID-19)-positive patients is quite intriguing. In this study, we have characterized the antibody titer, SARS-CoV-2 surrogate virus neutralization, cytokine levels, single-cell T-cell receptor (TCR), and B-cell receptor (BCR) profiling in asymptomatic direct contacts, infected cases, and controls. We observed significant increase in antibodies with neutralizing amplitude in asymptomatic contacts along with cytokines such as Eotaxin, granulocyte-colony stimulating factor (G-CSF), interleukin 7 (IL-7), migration inhibitory factor (MIF), and macrophage inflammatory protein-1α (MIP-1α). Upon single-cell RNA (scRNA) sequencing, we explored the dynamics of the adaptive immune response in few representative asymptomatic close contacts and COVID-19-infected patients. We reported direct asymptomatic contacts to have decreased CD4+ naive T cells with concomitant increase in CD4+ memory and CD8+ Temra cells along with expanded clonotypes compared to infected patients. Noticeable proportions of class switched memory B cells were also observed in them. Overall, these findings gave an insight into the nature of protection in asymptomatic contacts.

Abstract
CONTEXT Garden cress (GC), fenugreek (FG), and black seed (BS) are traditional herbal medicine for managing hypertension. OBJECTIVE The effects of the three herbs on the pharmacodynamics of metoprolol tartrate (MT) in hypertensive rats were investigated. MATERIALS AND METHODS Wistar rats were divided in five groups (n = 6). Group I served as normal control group and Group II (hypertensive control group) had rats treated orally with N-nitro L-arginine methyl ester (L-NAME, 40 mg/kg/day) only. Groups III, IV, and V rats were orally treated with L-NAME (40 mg/kg/day) + GC (300 mg/kg, once daily), L-NAME (40 mg/kg/day) + FG (300 mg/kg, once daily) and L-NAME (40 mg/kg/day) + BS (300 mg/kg, once daily), respectively, for 2 weeks, and on the 14th day, blood pressure and heart rate were recorded using a tail-cuff blood pressure-measuring system. On the 16th day, a single dose of MT (10 mg/kg) was orally administered, and the rats' blood pressure and heart rate were recorded. RESULTS GC, FG, and BS decreased systolic blood pressure (SBP) by 8.7%, 8.5%, and 8.7%, respectively, in hypertensive rats. A greater decrease in SBP by 14.5%, 14.8%, and 16.1% was observed when hypertensive rats were treated with L-NAME + GC + MT, L-NAME + FG + MT, and L-NAME + BS + MT, respectively. Similarly, hypertensive rats treated with the combination of herbs and MT had significantly lower diastolic blood pressure (DBP) than those treated with herbs alone and those treated with L-NAME alone. CONCLUSIONS The combination of investigated herbs and MT had a beneficial effect on hypertension. However, the concurrent administration of drugs, particularly those predominantly cleared through CYP450 2D6-catalyzed metabolism, with the three investigated herbs should be considered with caution.

Abstract
Members of the genus Ebolavirus (family Filoviridae) are among the deadliest viral pathogens spread throughout the world with severe rate of mortality, at least 90% in some outbreaks. Their virions are filamentous and enveloped with enclosed negative-sense single-stranded RNA genome. The genome potentially expresses seven structural and nonstructural proteins. The replication cycle is complex consisting of multiple molecular processes and interactions with human-host factors and proteins. Due to high mortality rate of infection, the studies regarding cure is still infancy. This review covers the current understanding of the virus replication cycle and vaccine development, and herbal treatments to control Ebola covering the available literature on the subject.

Abstract
Hyperglycemia and hyperlipidemia-arbitrated mitochondrial oxidative insult is key reason for cardiac dysfunction and cardiomyopathy. Sinapic acid (SA) is a hydroxycinnamic acid (a polyphenolic acid) present in multiple plants and possesses several pharmacological activities. In this study, we examined the cardio protective effects of SA on streptozotocin (STZ)-induced cardiac insults. STZ and both STZ induced diabetes and normal control rats were administered with 20 and 40 mg/kg SA for 12 weeks. STZ rats demonstrated hyperglycemia and hyperlipidemia. Additionally, STZ administered rats exhibited various histological changes in the cardiac muscles and significantly enhanced CK-MB and LDH. The significant enhancement of oxidative stress, inflammation, and apoptotic markers, and the capacity to curb oxidative stress was significantly abridged in the STZ induced diabetic heart. Chronic treatment with SA (20-40 mg/kg) ameliorated the increased level of glucose, lipid, and cardiac function markers and curtailed histological changes in the cardiac muscles. Chronic treatment also repressed inflammation, oxidative stress and apoptosis thereby and restoring antioxidant defenses in the myocardium of STZ induced diabetic rats. STZ induced cardiac dysfunction and cardiomyopathy by promoting inflammation and oxidative stress. Sinapic acid ameliorates cardiac dysfunction and cardiomyopathy via improvement of hyperglycemia, hyperlipidemia, inflammation, oxidative stress, and apoptosis. Thus, SA possesses possible therapeutic value for the prevention of diabetic cardiac dysfunction and cardiomyopathy via the NRF2/HO-1 and NF-κB pathways.
