Abstract
Artificial superhydrophobic surfaces that do not absorb water, like the lotus leaf, show tremendous promise in numerous applications. However, superhydrophobic surfaces are rarely used because of their low stability and endurance. A stable organic superhydrophobic surface (SHS) composed of novel morphology Ag-nanoparticles (NPs) has been fabricated on a copper alloy via etching, immersion, spraying, and annealing treatment, along with a static water contact angle (WCA) of 158 ± 1° and sliding angle (SA) less than 2°. The surface texture, composition, and morphology of the substrate surfaces were explored by using X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, energy dispersive spectroscopy, and DFT-based Ag atom distribution. The anti-corrosion study of non-coated and Ag-NP-coated copper alloy was undertaken using electrochemical impedance spectroscopy. Ag-NPs +SA@SHS enhanced the corrosion resistance as compared with bare Cu alloy. The water droplet rolled down the coated Cu alloy, removed the chalk powder from the surface, and indicated an excellent self-cleaning function. Photodegradation of Congo red (CR) and methylene blue (MB) dye samples was assessed by measuring the absorbance through UV-Visible spectrophotometry, where the Ag-NPs coated on the copper alloy were used as a catalyst. The performance of the SHS@Ag-NPs in the aqueous solution was 99.31% and 98.12% for industrial pollutants (CR and MB), with degradation rates of 5.81 × 10-2 s-1 and 5.89 × 10-2 s-1, respectively. These findings demonstrated a simple, rapid, and low-energy fabrication technique for SHS@Ag-NPs. This research reveals a valuable approach for the fabrication of SHS@Ag-NPs on various substrates to extend the superhydrophobic surfaces with ultra-fast self-healing properties, for outdoor applications such as anti-corrosion, for an innovative approach for the remediation of polluted water treatment, and for industrial applications.

Abstract
CRC accounts for approximately a tenth of all cancer cases and deaths in the US. Due to large differences in demographics among the different states, we aim to determine trends in the CRC epidemiology and across different states, age groups, and genders. CRC rates, age-adjusted to the standard US population, were obtained from the GBD 2019 database. Time trends were estimated as annual percentage change (APC). A pairwise comparison was conducted between age- and gender-specific trends using the tests of parallelism and coincidence. Age-specific trends were also assessed in two age subgroups: younger adults aged 15-49 years and older adults aged 50-74 years. We also analyzed the prevalence, incidence, mortality, and DALYs in the US between 1990 and 2019. A total of 5.53 million patients were diagnosed with CRC in the US between 1990 and 2019. Overall, CRC incidence rates have significantly increased in younger adults (11.1 per 100,000 persons) and decreased in older adults (136.8 per 100,000 persons) (AAPC = 1.2 vs. -0.6; AAPC difference = 1.8, p < 0.001). Age-specific trends were neither identical (p < 0.001) nor parallel (p < 0.001), suggesting that CRC incidence rates are different and increasing at a greater rate in younger adults compared to older adults. However, for both men and women (49.4 and 35.2 per 100,000 persons), incidence rates have decreased over the past three decades at the same rate (AAPC = -0.5 vs. -0.5; AAPC difference = 0, p = 0.1). Geographically, the southern states had the highest mortality rates with Mississippi having the highest rate of 20.1 cases per 100,000 population in 2019. Massachusetts, New York, and the District of Colombia had the greatest decreases in mortality over the study period (-42.1%, -41.4%, and -40.9%). Decreased mortality was found in all states except Mississippi, where the mortality of CRC increased over the study period (+1.5%). This research provides crucial insights for policymakers to tailor resource allocation, emphasizing the dynamic nature of CRC burden across states and age groups, ultimately informing targeted strategies for prevention and intervention.

Abstract
Neuroinflammation is primarily characterised by activation of the brain's resident macrophages - the microglia. However, other central nervous system (CNS) cells also contribute to this response, including the astrocytes and endothelial cells. In addition, there is infiltration into the CNS of peripherally derived immune cells. Together these cells mediate inflammation by the production of cytokines, chemokines, reactive oxygen species, and secondary messengers, and enacting of the appropriate response to those signals. However, deciphering the specific contributions of each cell type has been challenging. Studying CNS cell biology is often challenging, as the isolation of primary cells is not always feasible, and differentiation towards microglia-like cells is complex. Here, we demonstrate a novel method whereby THP-1 monocytic cells are differentiated into neural macrophage cells with microglia-like cell characteristics. The cells, designated mgTHP-1, show typical morphological and gene expression patterns of resident CNS macrophages and functionally respond to inflammatory stimuli by producing inflammatory cytokines. Furthermore, with the addition of Vicenin-2 (an anti-inflammatory flavonoid) such responses can be reversed. This novel cell model will allow further investigations, and hence insights, into the neuroinflammatory mechanisms associated with CNS diseases.

Abstract
Since Carl Woese's discovery of archaea as a third domain of life, numerous archaeal species have been discovered, yet archaeal diversity is poorly characterized. Culturing archaea is complicated, but several queries about archaeal cell biology, evolution, physiology, and diversity need to be solved by culturing and culture-dependent techniques. Increasing interest in demand for innovative culturing methods has led to various technological and methodological advances. The current review explains frequent hurdles hindering uncultured archaea isolation and discusses features for more archaeal cultivation. This review also discusses successful strategies and available media for archaeal culturing, which might be helpful for future culturing practices.

Abstract
Development of natural, broad-spectrum, and eco-friendly bio-fungicides is of high interest in the agriculture and food industries. In this context, Bacillus genus has shown great potential for producing a wide range of antimicrobial metabolites against various pathogens. A Bacillus velezensis strain FB2 was isolated from an agricultural field of National Institute for Biotechnology and Genetic Engineering (NIBGE) Faisalabad, Pakistan, exhibiting good antifungal properties. The complete genome of this strain was sequenced, and its antifungal potential was assayed by dual culture method. Moreover, structural characterization of its antifungal metabolites, produced in vitro, were studied. Genome analysis and mining revealed the secondary metabolite gene clusters, encoding non-ribosomal peptides (NRPs) production (e.g., surfactin, iturin and fengycin) and polyketide (PK) synthesis (e.g., difficidin, bacillaene and macrolactin). Furthermore, the Bacillus velezensis FB2 strain was observed to possess in vitro antifungal activity; 41.64, 40.38 and 26% growth inhibition against major fungal pathogens i.e. Alternaria alternata, Fusarium oxysporum and Fusarium solani respectively. Its lipopeptide extract obtained by acid precipitation method was also found effective against the above-mentioned fungal pathogens. The ESI-MS/MS analysis indicated various homologs of surfactin and iturin-A, responsible for their antifungal activities. Overall, this study provides a better understanding of Bacillus velezensis FB2, as a promising candidate for biocontrol purposes, acting in a safe and sustainable way, to control plant pathogens.

Abstract
In this study, novel stannous oxide@hafnium carbide (SnO@HfC) nanocomposite was successfully manufactured by an appropriate hydrothermal scheme which was utilized for the photocatalytic degradation of BPA by stimulation of peroxymonosulfate (PMS) and self-cleaning application. Numerous methods were applied for the characterization of photocatalyst and demonstrated the successful preparation of SnO@HfC nanocomposite. The crystal structures, band structures and density of states for SnO and HfC were explored by DFT analysis. The amazing PMS stimulation performance of SnO@HfC nanocomposite originated from the establishment of a heterojunction, which led to the enhancement of the light response aptitude and the electron conduction competence of the composite. BPA was degraded by 0.75 g/L PMS and SnO@HfC at neutral pH during the period of 60 min. In order to identify active groups in the reaction procedure, quenching experiments and electron paramagnetic resonance (EPR) approaches were also used. In the subsequent active species scavenging assays, where sulfate radicals, hydroxyl radicals, holes, and superoxide radicals were engaged in the degradation of BPA. While, liquid phase mass spectrometry (LC-MS) was used to pinpoint the intermediate metabolites in the course of degradation. SnO@HfC/PMS/light system delivered excellent TOC removal efficiency and less ions leaching. The SnO@HfC nanocomposite proved good durability and reusability in continuous cycle tests along with excellent self-cleaning function on the glass substrate. The SnO@HfC nanocomposite performs admirably in terms of self-cleaning application. The SnO@HfC nanocomposite is expected to be used in the future for the treatment of wastewater that contains pharmaceuticals due to its superior stability and reusability after five consecutive cycles.

Abstract
Bacterial biofilms are formed by communities, which are encased in a matrix of extracellular polymeric substances (EPS). Notably, bacteria in biofilms display a set of 'emergent properties' that vary considerably from free-living bacterial cells. Biofilms help bacteria to survive under multiple stressful conditions such as providing immunity against antibiotics. Apart from the provision of multi-layered defense for enabling poor antibiotic absorption and adaptive persistor cells, biofilms utilize their extracellular components, e.g., extracellular DNA (eDNA), chemical-like catalase, various genes and their regulators to combat antibiotics. The response of biofilms depends on the type of antibiotic that comes into contact with biofilms. For example, excessive production of eDNA exerts resistance against cell wall and DNA targeting antibiotics and the release of antagonist chemicals neutralizes cell membrane inhibitors, whereas the induction of protein and folic acid antibiotics inside cells is lowered by mutating genes and their regulators. Here, we review the current state of knowledge of biofilm-based resistance to various antibiotic classes in bacteria and genes responsible for biofilm development, and the key role of quorum sensing in developing biofilms and antibiotic resistance is also discussed. In this review, we also highlight new and modified techniques such as CRISPR/Cas, nanotechnology and bacteriophage therapy. These technologies might be useful to eliminate pathogens residing in biofilms by combating biofilm-induced antibiotic resistance and making this world free of antibiotic resistance.

Abstract
EDSS1, a syndrome characterized by ectodermal dysplasia-syndactyly, is inherited in an autosomal recessive manner due to mutations in the NECTIN4/PVRL4 gene. Clinical manifestations of the syndrome include defective nail plate, sparse to absent scalp and body hair, spaced teeth with enamel hypoplasia, and bilateral cutaneous syndactyly in the fingers and toes. Here, we report a consanguineous family of Kashmiri origin presenting features of EDSS1. Using whole exome sequencing, we found a recurrent nonsense mutation (NM_030916: c.181C > T, p.(Gln61 ∗)) in the NECTIN4 gene. The variant segregated perfectly with the disorder within the family. The candidate variant was absent in 50 in-house exomes pertaining to other disorders from the same population. In addition to the previously reported clinical phenotype, an upper lip cleft was found in one of the affected members as a novel phenotype that is not reported by previous studies in EDSS1 patients. Therefore, the study presented here, which was conducted on the Kashmiri population, is the first to document a NECTIN4 mutation associated with the upper lip cleft as a novel phenotype. This finding broadens the molecular and phenotypic spectrum of EDSS1.

Abstract
We measured the nuclear-recoil ionization yield in silicon with a cryogenic phonon-sensitive gram-scale detector. Neutrons from a monoenergetic beam scatter off of the silicon nuclei at angles corresponding to energy depositions from 4 keV down to 100 eV, the lowest energy probed so far. The results show no sign of an ionization production threshold above 100 eV. These results call for further investigation of the ionization yield theory and a comprehensive determination of the detector response function at energies below the keV scale.

Abstract
This study aimed to explore the potential of Host-Guest coupling with Nanocarrier graphyne (GPH) to enhance the bioavailability of the drug 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (LUM) for brain tumor therapy. The electronic, geometric, and excited-state properties of GPH, LUM, and the graphyne@1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea-complex (GPH@LUM-complex) were studied using DFT B3LYP/6-31G** level of theory. The results showed that the GPH@LUM-complex was stable with negative adsorption energy (-0.20 eV), and there was good interaction between GPH and LUM in the solvent phase. The weak interaction forces between the two indicated an easy release of the drug at the target site. The Frontier Molecular Orbitals (FMO), Charge Density Analysis (CDA), and Natural Bond Orbital (NBO) analysis supported LUM to GPH charge transfer during complex formation, and the Reduced Density Gradient (RDG) isosurfaces identified steric effects and non-bonded interactions. UV-visible examination showed the potential of the GPH@LUM-complex as a drug carrier with a blue shift of 23 nm wavelength in the electronic spectra. The PET process analysis revealed a fluorescence-quenching process, facilitating systematic drug delivery. The study concluded that GPH had potential as a carrier for delivering LUM, and different 2D nanomaterials could be explored for drug delivery applications. The theoretical study's findings may motivate researchers to investigate the practical applications of GPH@LUM-complex in oncology.

Abstract
Schistosomiasis is a parasitic infection endemic to sub-Saharan Africa. The severe form of disease, caused by deposition of Schistosoma eggs in the portal vein, is known as hepatosplenic schistosomiasis. We present a case of a 26-year-old woman with esophageal varices in the setting of hepatosplenic schistosomiasis. This patient underwent partial splenic artery embolization to treat thrombocytopenia secondary to splenic sequestration. After embolization and improvement of cell counts, the patient was successfully able to undergo variceal band ligation.

Abstract
Solitary extramedullary plasmacytoma (SEP) is a rare tumor due to the monoclonal proliferation of plasma cells without bone marrow involvement. Plasmacytomas are frequently encountered in bone or soft tissue but rarely occur in the gastrointestinal (GI) tract. They can present with a multitude of symptoms depending on their site. This report describes a case of SEP diagnosed as a duodenal ulcer (DU) during esophagogastroduodenoscopy (EGD) for iron deficiency anemia.

Abstract
We identified a novel homozygous disease-causing variant in TMC8 in a Pakistani family with epidermodysplasia verruciformis (EV). The phenotype of EV in the affected individuals was most probably caused by an aberrant splicing process. The molecular genetic findings in our patients expand the mutational spectrum of the disease.

Abstract
According to World Health Organization (WHO) survey, air pollution has become the major reason of several fatal diseases, which had led to the death of 7 million peoples around the globe. The 9 people out of 10 breathe air, which exceeds WHO recommendations. Several strategies are in practice to reduce the emission of pollutants into the air, and also strict industrial, scientific, and health recommendations to use sustainable green technologies to reduce the emission of contaminants into the air. Photocatalysis technology recently has been raised as a green technology to be in practice towards the removal of air pollutants. The scientific community has passed a long pathway to develop such technology from the material, and reactor points of view. Many classes of photoactive materials have been suggested to achieve such a target. In this context, the contribution of conjugated polymers (CPs), and their modification with some common inorganic semiconductors as novel photocatalysts, has never been addressed in literature till now for said application, and is critically evaluated in this review. As we know that CPs have unique characteristics compared to inorganic semiconductors, because of their conductivity, excellent light response, good sorption ability, better redox charge generation, and separation along with a delocalized π-electrons system. The advances in photocatalytic removal/reduction of three primary air-polluting compounds such as CO2, NOX, and VOCs using CPs based photocatalysts are discussed in detail. Furthermore, the synergetic effects, obtained in CPs after combining with inorganic semiconductors are also comprehensively summarized in this review. However, such a combined system, on to better charges generation and separation, may make the Adsorb & Shuttle process into action, wherein, CPs may play the sorbing area. And, we hope that, the critical discussion on the further enhancement of photoactivity and future recommendations will open the doors for up-to-date technology transfer in modern research.

Abstract
Introduction
The COVID-19 pandemic presented a global public-health crisis that demanded healthcare to adapt at an unprecedented pace. While challenging, it also created opportunities for the advancement of novel electronic-treatment-modalities. Telepsychiatry has emerged as an effective method to ensure continuity of care and ensure social distancing.1 Studies indicate that mental-health patients have higher rates of noncompliance to follow-up,
1 thus finding means to increase compliance is critical.
Objectives
The objectives of this study are to determine the impact of telepsychiatry on compliance to follow-up and to identify numbers of psychiatric/medical emergency-room visits, most common contributing factors for admission, and compliance in terms of diagnosis.
Methods
This IRB approved study is a retrospective chart-review, that aims to study children/adolescents (5-18 years) who presented to the Child&Adolescent-Psychiatry Outpatient-clinic from July-December 2020 and engaged in telepsychiatry, compared to a group of patients presented in July-December 2019-Pre-Covid19-Pandemic. A review of clinical characteristics including diagnosis, demographic information, medication, and treatment compliance will be compared as well as admissions to inpatient-psychiatry/emergency-room visits.
Results
Our total sample (N=252) included patients from 2019-Pre-COVID19 (N=111) and 2020 Telehealth during COVID19-Pandemic (N=141). Our data analysis using SPSF and T-test has shown that Telehealth has significantly increased follow-up compliance (Two-tailed P-value=0.04); 2019-Pre-COVID outreach mean=0.06, 2020-Telehealth-during COVID outreach mean=0.02); significantly decreased ER/CPEP visits (P-value=0.02), and decreased In-patient-unit admissions (P-value=0.02).
Conclusions
According to the presented study, the incorporation of telepsychiatry has increased the compliance to psychiatric-care in outpatient and decreased the emergency-room visits and inpatient admission. Sufficient resources and steps need to be taken to further strengthen telehealth services.

Abstract
Introduction Schizophrenia is a chronic and severe mental health disorder, affecting 20 million people worldwide. Diet is a social determinant of health and is among one of the modifiable prognostic factors for schizophrenics. Previous research in nutritional psychiatry has shown that a balanced and healthy diet in this patient population has the potential to improve cognition, decrease positive and negative symptoms of the disease, and improve the overall metabolic profile.1,3 Objectives
To understand the evidence on the role that nutritional supplements play in improving quality of life in Schizophrenia by improving cognitive symptoms and decrease mortality by decreasing chances of metabolic syndrome and CVD. Demonstrate how certain supplements can improve cognitive symptoms, and decrease positive and negative symptoms in schizophrenics Methods PubMed was used to search for articles within the past 10 years Results A total of 29 articles were initially generated, of which only 5 fit the search criteria. Each specific search produced more articles, and after carefully reading each, a total of 14 articles was determined to fit the criteria. All, but two articles included PANSS score assessment. The studies on vitamin D, cycloserine and omega 3’s produced conflicting Conclusions Supplementation of vitamin D, Konjac powder, D-cycloserine, sarcosine, and omega 3’s have the potential to improve symptomatology and enhance the quality of life of schizophrenics. D-serine and sodium benzoate have not been shown to be effective adjunctive treatments in schizophrenia. Due to a limited number of studies for each, more research is indicated to truly determine the public health significance. Disclosure No significant relationships.

Abstract
Introduction Methamphetamine associated psychosis has increased globally because of the increased usage of the substance. The use of risperidone is noted to reduce the cravings of methamphetamine in patients who have methamphetamine use disorder. This becomes relevant because the number of patients who are being treated with MAP tends to have high relapse rates. MAP is being treated with different antipsychotics and the treatment protocol is made usually for alleviating the symptoms, a formal treatment regimen for patients with MAP is yet to be developed (Chiang et al 2018; Srisurapanont 2021; Edwards and Mooney 2014) Objectives The purpose of this review is to highlight the use of risperidone in reducing the cravings of methamphetamine in patients who have methamphetamine use disorder Methods PubMed, SCOPUS and Web of Science literature databases were screened and filtered.With established Inclusion and exclusion criteria, obtained a total of 15578 hits which was refined to 133articles. A total of 10papers were reviewed in detail Results Multiple clinical trials have shown that risperidone was effective in lowering drug cravings in methamphetamine use disorder. Along with the effects on craving, risperidone has also been studied for its effect on positive symptoms in patients with MAP (Samei 2016). Risperidone was noted to be effective in reducing positive symptoms. Conclusions Risperidone can be effectively used in the acute setting for psychosis and future cravings in the patients. Considering the limited clinical trials and research on risperidone and the cravings of methamphetamine use disorder, studies are needed with longer follow-ups and more samples in the future.

Abstract
Introduction Studies have demonstrated that Ziprasidone use may be beneficial in children. Determining its potential risks and benefits when used in children is therefore important. Objectives To examine the tolerability of Ziprasidone, an atypical antipsychotic, in children and adolescents. Methods We conducted a literature search of open label or randomized control trials that report on Ziprasidone use in children on three databases: Embase, PsychInfo and PubMed using the PRISMA guidelines of Systematic review and Meta-analysis. Out of 1690 articles, 11 studies met inclusion criteria. Outcome measures included adverse effects such as weight gain, increase in BMI, QTc prolongation, changes in metabolic parameters, sedation, and dizziness. We conducted a random effects meta-analysis and meta-regression of potential moderators. Publication bias was assessed with funnel plots. Results Data from Eleven studies was meta-analyzed (Total n= 474, mean age=12.87 years, male= 68..37%) that reported the use of Ziprasidone in children and adolescents with Psychosis, Bipolar, Autism spectrum disorders and Tourettes syndrome. Mean Ziprasidone dose = 84.40 mg and mean study duration = 2.85 months). We found that Ziprasidone was not found to cause any significant weight gain (1.72, p>0.05) or change in BMI (0.58 , p>0.05). QTc prolongation was found to be significant (11.9 , p<0.05). Most common side effects were sedation (42.44%), Nausea(19.32%), Headache (22.92%), fatigue (16.67%) and Dizziness (16.96 %). Conclusions Results demonstrate that Ziprasidone does not cause significant weight gain, however QTc prolongation and sedation were found to be significant side effects of Ziprasidone use. Therefore, baseline EKG and thorough history must be obtained before prescribing Ziprasidone in children and adolescents. Disclosure No significant relationships.

Abstract
Introduction Over time the prevalence of methamphetamine associated psychosis (MAP) has increased globally including Asia and Europe. Shoptaw et al looked at an RCT and concluded that olanzapine is superior to haloperidol in terms of tolerability and the side effect profile as it causes fewer extrapyramidal symptoms. Another study by Xue et al compared the efficacy of olanzapine and haloperidol and found that they had comparable effects but the onset time in the olanzapine group was significantly earlier than the haloperidol group. Srisurapanont et al analyzed 6 RCTs and concluded that quetiapine and olanzapine are probably superior than aripiprazole and risperidone. Objectives The purpose of this review is to find out if olanzapine is better than other antipsychotics in treating methamphetamine-induced psychosis. Methods PubMed, SCOPUS, and Web of Science literature databases were screened and filtered by using specific search terms, inclusion/exclusion criteria. Texts of the selected articles and trials were reviewed and the search terms generated a total of 248 results from the databases. After applying the criteria 200 citations were left and 15 papers were reviewed. Results The literature review concluded that olanzapine can be used as an effective treatment for methamphetamine-induced psychosis. Olanzapine can help to reduce the psychotic symptoms in MAP with a quicker onset and lesser side effects. Conclusions Olanzapine can help in the treatment of methamphetamine-associated psychosis and can be considered as the first-line therapy. Research is further needed with a higher pool of candidates in the future to compare the efficacy and tolerability of different typical and atypical antipsychotics. Disclosure No significant relationships.

Abstract
Background The ever-increasing market of functional meat products demanded especially by modern health conscious consumers has prompted researchers to develop healthier meat products. Aims This experiment was conducted to improve the dietary fiber-deficient buffalo meat with natural functional fiber-rich extenders. Methods Meat obtained from the carcass of adult female buffalo (>10 years of age) was procured from the local market within 5-6 h of slaughter, conditioned for 24 h, and then processed by incorporating the dietary fiber-rich extenders at their optimum levels viz. 12% barley flour, 12% maize flour, 10% pea hull powder, and 8% wheat bran (hydrated as 1:1, w/w) for the development of functional restructured buffalo meat fillets (FRBMF). Results Results revealed higher cooking yield, pH, moisture content, lower protein, and fat percentage for most of the treated samples compared with the control group. The ash percentage of FRBMF prepared with the optimum level of pea hull powder and wheat bran was significantly higher (P<0.05) than in control and other treatments. Shear force values for FRBMF were lower than the control. Total dietary fiber (TDF) percentage of all the treatment products was significantly higher (P<0.05) than the control. Texture profile analysis revealed no significant differences (P>0.05) between FRBMF and the control. The sensory scores for most of the attributes of FRBMF incorporated with the optimum level of extenders were lower but comparable to the control. Conclusion It was concluded that the functionality of the product had improved, especially in terms of total dietary fiber, as compared to the control. Pea hull powder and wheat bran proved to be excellent sources of dietary fibers, followed by barley and maize flours, respectively.

Abstract
Butylated hydroxyanisole (BHA) is a synthetic antioxidant analogous of vitamin E. It is used as a preservative to prevent free radical-mediated oxidation in high-fat foods, and this study's objective was to investigate the effects of BHA on oxidative stress and apoptosis in addition to delineating its efficacy as a growth-promoting feed additive. 60 weaned male rabbits (V-line) were randomly divided into four equal groups: BHA0.0 (control), BHA50, BHA100, and BHA150, administered basal diets with 0.0, 50, 100, and 150 mg BHA/kg of feed for 60 days. Animals were examined for growth performance, markers of oxidative stress and apoptosis, and meat characteristics. Compared to the control group, rabbits receiving BHA-supplemented diets exhibited increases in BW and average daily gain (P < 0.01), where BHA50 and BHA100 groups showed increased muscle content of methionine aspartic acid, serine, and glutamine (P < 0.05). These two groups also exhibited elevated catalase and superoxide dismutase activities and diminished malondialdehyde levels in the liver. Butylated hydroxyanisole upregulated fatty acid synthase gene (FASN), especially in BHA100 animals. Bcl-2-associated X/B-celllymphoma-2 (Bax/Bcl-2) ratio significantly increased in animals receiving higher doses of BHA, and the weight of the liver significantly increased following BHA treatment. Supplementing growing rabbits with lower doses of dietary BHA may promote growth performance and meat quality via maintaining the redox balance. Hence, the 50-100 mg/kg may be recommended as a safe and still effective feed additive as well as an oxidative stress attenuator.

Abstract
Introduction Hockey is a team sport that involves running, sprinting, and making sudden changes in directions of movement to control a ball against the opposing team. Therefore, due to its nature of fast movement, hockey players may be at risk of various musculoskeletal injuries. This study aimed to identify the prevalence and pattern of musculoskeletal injuries sustained among Malaysian Hockey League players. Materials and Method Data were collected from 84 field hockey players that participated in the Malaysian Hockey League competition from June 2016 until December 2016. All injuries were recorded by the participating medical team using a structured questionnaire. A descriptive statistical analysis and Chi-Square test were used to explore the prevalence of the injury. Result More than half of the players were reported to have lower limb injuries (51.6%). Sprain and strain were the most prevalent injuries (63%) and mostly affected the ankle (29%). Male players sustained more injuries (50.8%) compared to female players (49.2%). Conclusion This study suggests that a guideline is needed for injury prevention strategies that will benefit the hockey players in preventing injuries.

Abstract
Abstract
Introduction
Sepsis is a life-threatening condition that is associated with increased mortality. Artificial intelligence tools can inform clinical decision making by flagging patients who may be at risk of developing infection and subsequent sepsis and assist clinicians with their care management.
Aim
To identify the optimal set of predictors used to train machine learning algorithms to predict the likelihood of an infection and subsequent sepsis and inform clinical decision making.
Methods
This systematic review was registered in PROSPERO database (CRD42020158685). We searched 3 large databases: Medline, Cumulative Index of Nursing and Allied Health Literature, and Embase, using appropriate search terms. We included quantitative primary research studies that focused on sepsis prediction associated with bacterial infection in adult population (>18 years) in all care settings, which included data on predictors to develop machine learning algorithms. The timeframe of the search was 1st January 2000 till the 25th November 2019. Data extraction was performed using a data extraction sheet, and a narrative synthesis of eligible studies was undertaken. Narrative analysis was used to arrange the data into key areas, and compare and contrast between the content of included studies. Quality assessment was performed using Newcastle-Ottawa Quality Assessment scale, which was used to evaluate the quality of non-randomized studies. Bias was not assessed due to the non-randomised nature of the included studies.
Results
Fifteen articles met our inclusion criteria (Figure 1). We identified 194 predictors that were used to train machine learning algorithms to predict infection and subsequent sepsis, with 13 predictors used on average across all included studies. The most significant predictors included age, gender, smoking, alcohol intake, heart rate, blood pressure, lactate level, cardiovascular disease, endocrine disease, cancer, chronic kidney disease (eGFR<60ml/min), white blood cell count, liver dysfunction, surgical approach (open or minimally invasive), and pre-operative haematocrit < 30%. These predictors were used for the development of all the algorithms in the fifteen articles. All included studies used artificial intelligence techniques to predict the likelihood of sepsis, with average sensitivity 77.5±19.27, and average specificity 69.45±21.25.
Conclusion
The type of predictors used were found to influence the predictive power and predictive timeframe of the developed machine learning algorithm. Two strengths of our review were that we included studies published since the first definition of sepsis was published in 2001, and identified factors that can improve the predictive ability of algorithms. However, we note that the included studies had some limitations, with three studies not validating the models that they developed, and many tools limited by either their reduced specificity or sensitivity or both. This work has important implications for practice, as predicting the likelihood of sepsis can help inform the management of patients and concentrate finite resources to those patients who are most at risk. Producing a set of predictors can also guide future studies in developing more sensitive and specific algorithms with increased predictive time window to allow for preventive clinical measures.

Abstract
Abstract
Introduction
Antimicrobial resistance is a global health problem, especially in developing countries. Antimicrobial Stewardship Programmes (AMS) have been shown to be effective at reducing antimicrobial resistance and hospital patient stays. Health information technology (HIT) can support Outpatient Parenteral Antimicrobial Therapy (OPAT) through more accurate diagnosis and management of infectious diseases.
Aim
To evaluate the knowledge and attitude of Egyptian healthcare professionals towards the application of HIT to optimize OPAT.
Methods
Healthcare professionals who worked in either private or public sectors of Egyptian healthcare system were emailed and asked if they would be willing to complete an electronic questionnaire (using google forms). One reminder was sent by email each week for two weeks (two in total) from the first invitation. The survey was laid out in four sections. The first section included specific details about the healthcare professional’s current employment and role, the second related to HIT services available in their organisations, the third covered their training in HIT and antimicrobial stewardship programmes, and the fourth included their use of HIT to optimize OPAT. Ethical approval was obtained from National Heart Institute, Egypt. Descriptive analysis was carried out for all the variables. One-way ANOVA testing at level of significance P-value <0.05, was used to compare numerical variables. SPSS version 26 was used for statistical analysis.
Results
Three hundred and eighty-five healthcare professionals were invited to respond to the questionnaire. (The response rate was 75.34% (290)). Of these, 152 (52.6%) were pharmacists, 134 (46.4%) physicians, and 3 (1%) nurses, and many participants (30.8%) had between 6 to 10 years of experience working in either outpatient or in-patient units. Only 15.2% of respondents mentioned that they have access to OPAT in their organizations, 51.2% did not have the service, while 33.6% responded that they did not know if the service was available. However, 27.3% had a training on ASP and 18.3% had a training on HIT. Mean scores for both knowledge (14.31±5.49) and attitude (14.67±2.53) were significantly higher in professionals who had received training in HIT (p = 0.003 & 0.006 respectively). However, scores for attitude were better than scores for knowledge.
Conclusions
In developing countries, HIT applications in OPAT are still in their infancy with only a few organisations adopting them. Egyptian healthcare professionals showed positive attitudes towards HIT use, especially when their knowledge was improved through training. Two strengths of this study include our high response rate and the wide breadth of different healthcare professionals who responded from both private and public healthcare settings. However, being a questionnaire, some questions were left unanswered and some respondents may not have been aware of their reasons for a particular answer. That said, this study has important implications for practice, with more awareness amongst healthcare professionals required on the availability of HIT services in their hospitals and how further training may be needed on the applications of HIT in optimizing OPAT.

Abstract
Background:Women represent an increasing proportion of the overall rheumatology workforce, but are underrepresented in academic rheumatology, especially in leadership roles [1].Objectives:The EULAR Task Force on Gender Equity in Academic Rheumatology has been convened to establish the extent of the unmet need for support of female rheumatologists, health professionals and non-clinical scientists in academic rheumatology and develop a framework to address this through EULAR and EMEUNET.Methods:To investigate gender equity in academic rheumatology, an anonymous web-based survey was targeted at the membership of EULAR and Emerging EULAR Network (EMEUNET) and their wider networks. The survey was developed based on a narrative literature review [1], best practice from The Association of Women in Rheumatology, a survey of task force members and face-to-face task force discussions. Personal experiences were explored and 24 potential interventions to aid career advancement were ranked. Statistics were descriptive with significance testing for male/female responses compared using chi-squared/t-tests. The level of significance was set at p<0.001.Results:A total of 301 respondents from 24 countries fully completed the survey. By profession, 290 (86.4%) were rheumatologists, 19 (6.3%) health professionals, and 22 (7.3%) non-clinical scientists. By gender, 217 (72.1%) were women, 83 (27.6%) men, and 1 (0.3%) third gender. By age, 203 (67.5%) were 40 or under. By ethnicity, 30 (10.0%) identified themselves as ethnic minority. A high proportion of respondents reported having experienced gender discrimination (47.2% total: 58.1% for women and 18.1% for men) and sexual harassment (26.2%: 31.8% and 10.8% respectively) (Figure 1). Chi-squared tests on the numbers on which these proportions were based showed statistically significant differences between women and men in having experienced gender discrimination (Χ2=36.959 (df=1), p <0.001) and sexual harassment (Χ2=12.633 (df=1), p <0.001). The highest-ranked interventions for career advancement regardless of respondents’ gender included: leadership skills training; speaking/presentation/communication skills training; information on training/career pathways; effective career planning training; support on grant writing applications; and high-impact scientific writing master-classes (Figure 2). Only 8 of 24 proposed interventions showed a significantly higher ranking (p<0.001) by female respondents and these typically related to promotion of female role models and gender-balance in committees, editorial boards and research funding (Figure 2).Figure 1.Perceived gender discrimination and sexual harassment, 301 responsesFigure 2.Mean perceived utility of potential interventions for career advancement by gender and statistically significant gender differences (p<.001), 300 responsesConclusion:The results of the survey will inform the development of task force policy proposals for interventions to support career advancement among EULAR and EMEUNET members.

Abstract
Bacteria inhabiting non-polar glaciers are exposed to large variations in temperature, which significantly affects the fluidity of bacterial cell membranes. In order to maintain normal functions of the cell membranes, psychrophilic bacteria adapt by changing the composition of cell membrane fatty acids. However, information on the exact pattern of cell membrane adaptability in non-polar low-temperature habitats is scarce. In the present study, 42 bacterial strains were isolated from the Ghulmet, Ghulkin, and Hopar glaciers of the Hunza Valley in the Karakoram Mountain Range, Pakistan and their cell membrane fatty acid distributions studied, using gas chromatography/mass spectrometry (GC-MS) for the analysis of fatty acid methyl esters (FAMEs) liberated by acid-catalyzed methanolysis. Furthermore, Gram-negative and Gram-positive groups were grown under different temperature settings (5, 15, 25, and 35°C) in order to determine the effect of temperature on cell membrane (CM) fatty acid distribution. The analyses identified the major groups of cell membrane fatty acids (FA) as straight-chain monounsaturated fatty acids (n-MUFAs) and branched fatty acids (br-FAs), accounting for more than 70% of the fatty acids analyzed. The distribution of br-FAs and n-FAs in bacterial cell membranes was significantly affected by temperature, with the level of br-FAs decreasing relative to n-FAs with increasing temperature. Notably, the production of polyunsaturated fatty acids (PUFAs) was only seen at lower temperatures. This study contributes to understanding, for the first time, the role of br-FAs in the maintenance of cell membrane fluidity of bacteria inhabiting non-polar habitats.

Abstract
Microorganisms play an important role in the fermentation of soy sauce as they produce
flavoring compounds which contribute to the desired taste and quality of soy sauce. The
aim of this study was to isolate and identify halophilic microorganisms that are involved
in the first stage (Koji) and second stage (Moromi) of soy sauce fermentation. In this
study, soy sauce samples were collected from a local company located in Johor Bahru.
The microorganisms were identified using Analytical Profile Identification (API) system
and 16s ribosomal RNA (bacteria)/Internal Transcribed Spacer region (fungi and yeast)
sequencing. In the koji fermentation, one fungus was isolated and identified as Aspergillus
oryzae. During the moromi fermentation, one lactic acid bacteria and two yeasts were
identified, including Tetragenococcus halophilus, Candida versatilis and Candida
etchellsii. These halophilic microorganisms can be used as starter culture in moromi stage
to shorten the fermentation period.

Abstract
The Hindu Kush mountains spread over Northern areas of Pakistan having hundreds of glaciers representing a unique ecosystem driven by the specific geochemistry and climate. The current study measured the distribution of culturable fungi in Tirich Mir glacier, Hindu Kush range, and the potential of these isolates to show antimicrobial activity and produce biotechnologically important enzymes. Samples of glacial ice, sediments, and meltwater were collected from Tirich Mir glacier, and 46 fungal strains were isolated and characterized for identity and biotechnological applications. The findings revealed Penicillium (10) as the most common genus, followed by Alternaria (9), Cladosporium (7), Coprinopsis, two isolates each belonging to genus Phoma, Ulocladium, Epicoccum, Onygenales, and Didymella, and one isolate of genus Davidiella, Aspergillus, Geomyces, Dothideomycetes, Pseudogymnoascus, Irpex, Scopulariopsis, Ascochyta, Tomicus, and Davidiellaceae. Davidiella tassiana HTF9 showed growth in the presence of 18% NaCl and pH 2, 3, 5, 7, 9, and 11. The isolates Ulocladium sp. and Onygenales sp. inhibited the growth of test fungi, Gram-negative and positive bacteria. Fungal strains were capable of producing cold-active enzymes, including cellulase, lipase, amylase, and deoxyribonuclease. The isolate Penicillium chrysogenum HTF24 was an efficient producer of amylase, deoxyribonuclease, and cellulase. The fungi of high-altitude glaciers are potent candidates for biotechnological applications; however, studies using more sensitive techniques are needed for further exploration.

Abstract
Abstract
Background
Serotonin (5-hydroxytryptamine; 5-HT), an enteric signalling molecule mainly produced by the enterochromaffin (EC) cells of the intestinal epithelium regulates various processes of the gut. Tryptophan hydroxylase 1 (Tph1) is the rate-limiting enzyme of 5-HT biosynthesis in EC cells. In inflammatory bowel disease (IBD) and experimental colitis, there are alterations in 5-HT content and microbiota composition in the gut. Previously we reported, Tph1-deficient (Tph1-/-) mice with reduced 5-HT in the gut exhibit reduced susceptibility to colitis. The mechanism by which 5-HT regulates colitis is unknown. Autophagy, a catabolic process regulates the function of intestinal epithelial cells (IECs), gut microbiota, and protects against intestinal inflammation. Both aberrant 5-HT signalling and autophagy is implicated in colitis. It is unclear whether they interact in regulation of production of pro-inflammatory cytokines from IECs and gut microbiota composition in relation to colitis. Our hypothesis is, an increase in 5-HT signalling inhibits autophagy in the IECs, which results in up-regulation of colitis by increasing the production of pro-inflammatory cytokines, and by selection for a more colitogenic microbiota.
Aims
To define the role of 5-HT-autophagy axis in the production of pro-inflammatory cytokines from IECs and gut microbiota composition in intestinal inflammation.
Methods
We investigated level of autophagy with or without 5% dextran sodium sulphate (DSS) in colons, mucosal scraping and IECs of Tph1-/- and their wild-type (WT) littermates. In addition, autophagy and proinflammatory cytokine production were investigated in human colonic epithelial cells (HT-29) following stimulation by 5-HT. We evaluated colitis and gut microbiota composition in WT, Tph1-/-, epithelial-specific autophagy gene Atg7 deficient (Atg7ΔIEC), and Atg7ΔIECTph1-/- (double knock out; DKO) mice.
Results
Tph1 -/- mice, with less 5-HT in the gut than WT mice following DSS administration exhibited an up-regulation of autophagy markers in the colon, mucosal scraping and IECs along with reduction of colitis severity. 5-HT treatment of HT-29 cells resulted in down-regulation of autophagy and upregulation of pro-inflammatory cytokine, IL-8. DKO mice exhibited increased severity of DSS-colitis, and altered microbiota composition compared to Tph1-/- mice.
Conclusions
These findings suggest, an increase in 5-HT in colitis inhibits autophagy in the IECs that contribute to alteration of the gut microbiota and disease severity. Blocking 5-HT signalling may promote autophagy in the IECs and alleviate the severity of colitis. Understanding the contribution of 5-HT in autophagy may identify new therapeutic target in IBD and other intestinal inflammatory conditions that exhibit dysregulated autophagy.

Abstract
Cystic echinococcosis (CE) is of increasing public health and socio-economic concern because of the large morbidity rates and produced high economic losses in the livestock industry. The objective of the current research was to study the reliability of indirect ELISA in detecting CE, based on two dif-ferent types of crude antigens of camel origin; protoscolex and germinal layer antigens from hydatid cyst. Blood samples were collected from 284 (125 slaughtered and 159 live camels). Out of 125 slaughtered camels examined visually, 55 (44%) were found to have hydatid cysts. Of them, 52/125 (41.6%) and 3/125 (2.4%) harboured hydatid cysts in lungs and livers respectively. Fertile lung cysts were 32.8%; 26.9% were sterile, while 40.3% of lung and liver cysts were calcified. The sensitivity of ELISA was 83% and 46.5% when protoscolex and germinal layer antigens were used, respectively. The respective specificity of antigens of protoscolex and germinal layer was 70.3% and 41.7%. The protoscolex antigen showed higher accuracy (73.6%) compared to the germinal layer antigen (52.8%). The cross reactivity of these antigens were evaluated with antigens and hyperimmune sera of CE and Fasciola spp. and Haemonchus contortus using ELISA. The results showed also weak immunogenic potency of each antigen with Fasciola spp. hyperimmune sera at dilution 1:50 while hyperimmune sera of Haemonchus contortus did not bind any antigen.
