Abstract
Natural scaffolds have been the cornerstone of tissue engineering for decades, providing ideal environments for cell growth within extracellular matrices. Previous studies have favored animal-derived materials, including collagen, gelatin, and laminin, owing to their superior effects in promoting cell attachment, proliferation, and differentiation compared to non-animal scaffolds, and used immortalized cell lines. However, for cultured meat production, non-animal-derived scaffolds with edible cells are preferred. Our study represents the first research to describe plant-derived, film-type scaffolds to overcome limitations associated with previously reported thick, gel-type scaffolds completely devoid of animal-derived materials. This approach has been employed to address the difficulties of fostering bovine muscle cell survival, migration, and differentiation in three-dimensional co-cultures. Primary bovine myoblasts from Bos Taurus Coreanae were harvested and seeded on alginate (Algi) or corn-derived alginate (AlgiC) scaffolds. Scaffold functionalities, including biocompatibility and the promotion of cell proliferation and differentiation, were evaluated using cell viability assays, immunofluorescence staining, and reverse transcription-quantitative polymerase chain reaction. Our results reveal a statistically significant 71.7% decrease in production time using film-type scaffolds relative to that for gel-type scaffolds, which can be maintained for up to 7 days. Film-type scaffolds enhanced initial cell attachment owing to their flatness and thinness relative to gel-type scaffolds. Algi and AlgiC film-type scaffolds both demonstrated low cytotoxicity over seven days of cell culture. Our findings indicated that PAX7 expression increased 16.5-fold in alginate scaffolds and 22.8-fold in AlgiC from day 1 to day 3. Moreover, at the differentiation stage on day 7, MHC expression was elevated 41.8-fold (Algi) and 32.7-fold (AlgiC), providing initial confirmation of the differentiation potential of bovine muscle cells. These findings suggest that both Algi and AlgiC film scaffolds are advantageous for cultured meat production.

Abstract
Palliative care is a valued aspect of clinical care which is an urgent humanitarian need for people worldwide with cancer and other chronic fatal diseases. Patients experience many different symptoms including severe pain in advanced cancer. Palliative care focuses on relief from symptoms, pain and stress by using different analgesics and adjuvant. The goal of palliative care is to improve the quality of life. So, this prospective observational study was carried out to assess pattern of drugs used and their response to pain in cancer patients attending out-patient department of palliative care service in two teaching hospitals of Bangladesh. One hundred forty (140) cancer patients were purposively selected who attended in out-patient department of palliative care unit in Bangabandhu Sheikh Mujib Medical University (BSMMU) and Dhaka Medical College Hospital (DMCH) from July 2018 to June 2019. Outcome variables were commonly presenting complaints, pain intensity, commonly prescribed drugs and analgesic prescription according to WHO three-step analgesic ladder, etc. The mean age ±SD of the respondents was 51.30±15.38 years, male-female ratio 1:1. Common sites of cancer were alimentary origin (20.0%), genitourinary system (17.86%), hepatobiliary system (11.43%), respiratory system (10.71%). The prescribed drugs were analgesics (96.4%), PPIs (74.3%), laxatives (62.1%), anti-emetics (38.6%), multivitamins (32.9%), H2 antagonists (17.1%), sedatives (17.1%), and corticosteroids (8.6%). Level 1 analgesics (Paracetamol or other NSAIDs) were prescribed to 42.65%, level 2 analgesics (Tramadol) were prescribed to 50.00% patients and level 3 analgesics (Morphine) were prescribed to 51.42% patients. The relation between and receiving three levels of analgesic prescriptions was statistically significant. The association between level of analgesic prescription was significant with site of cancer (p<0.001) and intensity of pain (p<0.001). This study showed that morphine was prescribed to more than half of the patients. Other level of analgesics were also used either single or in combination. Younger and male patients were treated more with level III analgesics. Prescribing analgesics were dependent on sites of cancer and intensity of pain.

Abstract
OBJECTIVES To assess the effect of simvastatin on uterine leiomyoma growth and extracellular matrix (ECM) deposition. DESIGN Laboratory analysis of human leiomyoma cell culture, xenograft in a mouse model, and patient tissue from a clinical trial. SETTING Academic research center. PATIENT(S) Tissue culture from human leiomyoma tissue and surgical leiomyoma tissue sections from a placebo-controlled randomized clinical trial. INTERVENTION(S) Simvastatin treatment. MAIN OUTCOME MEASURE(S) Serum concentrations, xenograft volumes, and protein expression. RESULTS Mice xenografted with 3-dimensional human leiomyoma cultures were divided as follows: 7 untreated controls; 12 treated with activated simvastatin at 10 mg/kg body weight; and 15 at 20 mg/kg body weight. Simvastatin was detected in the serum of mice injected at the highest dose. Xenograft volumes were significantly smaller (mean 53% smaller at the highest concentration). There was dissolution of compact ECM, decreased ECM formation, and lower collagen protein expression in xenografts. Membrane type 1 matrix metalloproteinase was increased in vitro and in vivo. Matrix metalloproteinase 2 and low-density lipoprotein receptor-related protein 1 were increased in vitro. CONCLUSIONS Simvastatin exhibited antitumoral activity with ECM degradation and decreased leiomyoma tumor volume in vivo. Activation of the matrix metalloproteinase 2, membrane type 1 matrix metalloproteinase, and low-density lipoprotein receptor-related protein 1 pathway may explain these findings.

Abstract
This paper presents the data on growth performance of marine Chlorella sp. cultured in different cost-effective media including cow dung, cow urine, poultry litter, compost, NPK (nitrogen, phosphorus, and potassium), and UTR (Urea, TSP, and red potash). Growth curve of Chlorella sp. was determined at 5 mg of cow dung, poultry litter, compost, NPK, UTR and 5 µL of cow urine per 350 ml sea water (25 ppt) to identify the onset of stationary phase. Further four media among these were selected to continue the experiment at 8 mg and 11 mg of concentration. The higher cell densities were 4.21 × 106 and 4.18 × 106 cells/mL for NPK at 8 mg and 11 mg of concentration on 6th and 5th day, respectively. Cow dung with an 11 mg of concentration exhibited 2.67 × 106 cells/mL on the 3rd day, which is around 1.5 times greater than the highest growth in the same concentration of poultry litter. Chlorella sp. had a higher cell density in NPK media than in other media, however it was discarded since it is inorganic and costly. Due to the low cell density in cow urine media and the prolonged stationary phase in poultry litter media, the focus of the subsequent study was then placed on cow dung media. The data will contribute to the selection of locally available and cost-effective culture media by determining the stationary phases for specific microalgal species which will replace the costly and labor-intensive commercial media.

Abstract
This systematic review aimed to explore the monitoring and evaluation (M&E) and operational research (OR) practices during public health emergencies (PHE) in the southeast Asian region (SEAR) over the last decade. We searched electronic databases and grey literature sources for studies published between 2012 and 2022. The studies written in English were included, and a narrative synthesis was undertaken. A total of 29 studies were included in this review. Among these 25 studies documented M&E and four studies documented OR practices. The majority of the studies were from India and Bangladesh, with no evidence found from Sri Lanka, Bhutan, Myanmar, and Timor-Leste. M&E of surveillance programs were identified among which PHE due to COVID-19 was most prevalent. M&E was conducted in response to COVID-19, cholera, Nipah, Ebola, Candida auris, and hepatitis A. OR practice was minimal and reported from India and Indonesia. India conducted OR on COVID-19 and malaria, whereas Indonesia focused on COVID-19 and influenza. While most SEAR countries have mechanisms for conducting M&E, there is a noticeable limitation in OR practices. There is a compelling need to develop a standard framework for M&E. Additionally, enhancing private sector engagement is crucial for strengthening preparedness against PHE. Furthermore, there is a necessity to increase awareness about the importance of conducting M&E and OR during PHE.

Abstract
BACKGROUND Prescribed fires often have ecological benefits, but their environmental health risks have been infrequently studied. We investigated associations between residing near a prescribed fire, wildfire smoke exposure, and heart failure (HF) patients' hospital utilization. METHODS We used electronic health records from January 2014 to December 2016 in a North Carolina hospital-based cohort to determine HF diagnoses, primary residence, and hospital utilization. Using a cross-sectional study design, we associated the prescribed fire occurrences within 1, 2, and 5 km of the patients' primary residence with the number of hospital visits and 7- and 30-day readmissions. To compare prescribed fire associations with those observed for wildfire smoke, we also associated zip code-level smoke density data designed to capture wildfire smoke emissions with hospital utilization amongst HF patients. Quasi-Poisson regression models were used for the number of hospital visits, while zero-inflated Poisson regression models were used for readmissions. All models were adjusted for age, sex, race, and neighborhood socioeconomic status and included an offset for follow-up time. The results are the percent change and the 95% confidence interval (CI). RESULTS Associations between prescribed fire occurrences and hospital visits were generally null, with the few associations observed being with prescribed fires within 5 and 2 km of the primary residence in the negative direction but not the more restrictive 1 km radius. However, exposure to medium or heavy smoke (primarily from wildfires) at the zip code level was associated with both 7-day (8.5% increase; 95% CI = 1.5%, 16.0%) and 30-day readmissions (5.4%; 95% CI = 2.3%, 8.5%), and to a lesser degree, hospital visits (1.5%; 95% CI: 0.0%, 3.0%) matching previous studies. CONCLUSIONS Area-level smoke exposure driven by wildfires is positively associated with hospital utilization but not proximity to prescribed fires.

Abstract
BACKGROUND Malaria exists as an endemic in many countries including Bangladesh and the malaria vaccine is not yet available here. The study aimed to assess the level of knowledge and acceptance of the malaria vaccination among the parents of children under the age of five in Bangladesh's malaria-endemic areas and the sociodemographic, behavioural, and household factors associated with the acceptance and knowledge of the malaria vaccine. METHODS From January to March 2022, a cross-sectional study was conducted in all five malaria-endemic districts of Bangladesh, involving 405 parents of children under the age of 5 who met the inclusion criteria. Multiple logistic regression was used to analyze the factor affecting parents' acceptance and knowledge of malaria vaccination in children under five and other variables. RESULTS Majority (54%) of the respondents were mothers. Almost half (49%) of the respondents were aged between 26 and 35 years old and around 90% were from rural areas. A small portion (20%) of the participants were housewives and 46% of them completed primary education. Overall, 70% of the study participants reported that they would accept malaria vaccination independently. About one-fourth (25%) heard about the malaria vaccine and 48% of them mentioned health professionals as the source of information. Knowledge of malaria vaccination was found associated with residence, income, and family size. Acceptance and knowledge were both associated with residence, education, occupation, income, and family size. In a multivariable analysis, housing structure, house wall, house window, knowledge of malaria, testing for malaria, and being diagnosed with malaria were all associated with knowledge of and acceptance of getting vaccinated against malaria. CONCLUSIONS The present study highlights the necessity of creating awareness of malaria vaccines in epidemic areas of Bangladesh. This study offers crucial data to develop a policy for a novel malaria vaccine, supporting its adoption in Bangladesh. PUBLIC CONTRIBUTION This study was based on interviews. The interviewees were recruited as public representatives from the malaria-endemic area to assist us in building an understanding of knowledge and acceptance of the malaria vaccine among parents of under-five children in Bangladesh.

Abstract
Introduction Carbon-tetrachloride (CCl4) is well-known to cause liver damage due to severe oxidative stress. Nerol, on the other hand, is a monoterpene that is antioxidant, antiviral, antibacterial, anti-inflammatory, and anxiolytic. This study set out to determine if nerol may be used as a prophylactic measure against the oxidative stress mediated hepatic injury caused by CCl4. Materials and methods For the aim of this experiment, 35 male Sprague-Dawley rats ranging in body weight (BW) from 140 to 180 g were split into five separate groups. With the exception of vehicle control group 1, all experimental rats were subjected to carbon tetrachloride exposure through intra-peritoneal injection at a 0.7 mL/kg body weight dose once a week for 4 weeks (28 days). The treatment groups 3 and 4 received oral administration of nerol at 50 and 100 mg/kg BW for 28 days. In the same time period, the standard control group received 100 mg/kg BW silymarin. Results Serum hepatic markers, lipid profiles, albumin, globulin, bilirubin, and total protein were all substantially improved in nerol-treated rats in a dose-dependent manner that had been exposed to CCl4 compared to the only CCl4-treated group. Carbon tetrachloride-exposed rats had lower glutathione, superoxide dismutase, and catalase levels and higher thio-barbituric acid reactive substances (TBARS) levels than normal rats. In contrast, administration of nerol shown a significant augmentation in the concentrations of these antioxidant compounds, while concurrently inducing a decline in the levels of TBARS in the hepatic tissue. In a similar vein, the histo-pathological examination yielded further evidence indicating that nerol offered protection to the hepatocyte against damage generated by CCl4. Conclusion According to the findings of our investigation, nerol has potential as a functional element to shield the liver from harm brought on by ROS that are caused by CCL4.

<b>Background and Objective:</b> Fixed oils used in traditional therapies also called volatile oils are generally aromatic oils obtained by the steam or hydrodistillation of plants. Different parts of plants have been used to obtain fixed oils. This study estimates the chemical constituents and <i>in vitro</i> antibacterial activity of fixed oils extracted by petroleum ether from the leaves, roots, stems and fruit part of <i>Bridelia stipularis</i> (L.). <b>Materials and Methods:</b> The natural fatty acids were extracted from different parts of <i>B. stipularis</i> by using petroleum ether. The fixed oils were studied by gas chromatography-mass spectrophotometry. The antibacterial test was carried out by the agar disc diffusion method. A Student's t-test was computed for the statistical significance of the results. <b>Results:</b> It showed 10 compounds from the leaf and 5 compounds from the stem. In both cases, the major components were methyl decanoate 93.56 and 74.98%, respectively. From the root parts, 6 compounds were identified in which the major compound was methyl linolelaidate (36.86%). Two compounds were identified from the fruit part and the major portion was methyl pentadecanoate (98.20%). The <i>in vitro</i> antibacterial potentials of the oils were tested against four pathogenic bacteria. Among the four fixed oils, the stem, leaf and root showed the strongest activity against <i>E. coli</i> (30, 21 and 15 mm). On the other hand, fruit fixed oil showed the highest zone of inhibition against <i>Bacillus cereus</i> (25 mm). <b>Conclusion:</b> The fixed oils of <i>B. stipularis</i> plant have the potential to be applied as an antibacterial agent, which can be selected for further analysis and can be used to discover bioactive natural products that may serve as leads in the development of new pharmaceuticals that address unmet therapeutic needs.

Abstract
Leiomyomas (fibroids) are monoclonal tumors in which myometrial stem cells (MSCs) turn tumorigenic after mutation, abnormal methylation, or aberrant signaling. Several factors contribute to metabolic dysfunction in obesity, including abnormal cellular proliferation, oxidative stress, and DNA damage. The present study aims to determine how adipocytes and adipocyte-secreted factors affect changes in MSCs in a manner that promotes the growth of uterine leiomyomas. Myometrial stem cells were isolated from the uteri of patients by fluorescence-activated cell sorting (FACS) using CD44/Stro1 antibodies. Enzyme-linked immunosorbent assay (ELISA), Western blot, and immunocytochemistry assays were performed on human adipocytes (SW872) co-cultured with MSCs and treated with leptin or adiponectin to examine the effects of proliferation, extracellular matrix (ECM) deposition, oxidative damage, and DNA damage. Co-culture with SW872 increased MSC proliferation compared to MSC culture alone, according to 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) results. The expressions of PCNA and COL1A increased significantly with SW872 co-culture. In addition, the expression of these markers was increased after leptin treatment and decreased after adiponectin treatment in MSCs. The Wnt/β-catenin and TGF-β/SMAD signaling pathways promote proliferation and ECM deposition in uterine leiomyomas. The expression of Wnt4, β-catenin, TGFβ3, and pSMAD2/3 of MSCs was increased when co-cultured with adipocytes. We found that the co-culture of MSCs with adipocytes resulted in increased NOX4 expression, reactive oxygen species production, and γ-H2AX expression. Leptin acts by binding to its receptor (LEP-R), leading to signal transduction, resulting in the transcription of genes involved in cellular proliferation, angiogenesis, and glycolysis. In MSCs, co-culture with adipocytes increased the expression of LEP-R, pSTAT3/STAT3, and pERK1/2/ERK/12. Based on the above results, we suggest that obesity may mediate MSC initiation of tumorigenesis, resulting in leiomyomas.

Abstract
Importance Urinary tract infection (UTI) is one of the most common infections encountered in infancy and childhood. Despite the emerging problem of antibiotic resistance in recent years, the use of antibiotics for better management of UTIs is inevitable. Objective This study aims to explore the efficacy and adverse effects of the available antimicrobial agents that are used in pediatric UTIs in low- and middle-income countries (LMICs). Methods Five electronic databases were searched to identify relevant articles. Two reviewers independently performed screening, data extraction, and quality assessment of the available literature. Randomized controlled trials providing antimicrobial interventions in both male and female participants within the age range of 3 months to 17 years in LMICs were included. Results Six randomized controlled trials from 13 LMICs were included in this review (four trials explored the efficacy). Due to high heterogeneity across the studies, a meta-analysis was not performed. Other than attrition and reporting bias, the risk of bias was moderate to high due to poor study designs. The differences in the efficacy and adverse events of different antimicrobials were not found to be statistically significant. Interpretation This review indicates the necessity for additional clinical trials on children from LMICs with more significant sample numbers, adequate intervention periods, and study design.

Abstract
Dietary factors influence male reproductive function in both experimental and epidemiological studies. However, there are currently no specific dietary guidelines for male preconception health. Here, we use the Nutritional Geometry framework to examine the effects of dietary macronutrient balance on reproductive traits in C57BL/6 J male mice. Dietary effects are observed in a range of morphological, testicular and spermatozoa traits, although the relative influence of protein, fat, carbohydrate, and their interactions differ depending on the trait being examined. Interestingly, dietary fat has a positive influence on sperm motility and antioxidant capacity, differing to typical high fat diet studies where calorie content is not controlled for. Moreover, body adiposity is not significantly correlated with any of the reproductive traits measured in this study. These results demonstrate the importance of macronutrient balance and calorie intake on reproductive function and support the need to develop specific, targeted, preconception dietary guidelines for males.

Abstract
OBJECTIVE To assess the diagnostic accuracy of stool specimens to diagnose pulmonary tuberculosis (PTB) in adults. DESIGN Systematic review. DATA SOURCES MEDLINE (Ovid), Embase (Ovid), Web of Science and the Cochrane database were searched from inception to 9 March 2023-10 March 2023 using a comprehensive search strategy; reference lists of selected articles and relevant review articles were manually searched. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Studies in English reporting diagnostic performance of stool specimens against respiratory specimens using mycobacterial culture or smear microscopy or Xpert assay to diagnose PTB in adults were eligible for this systematic review. DATA EXTRACTION AND SYNTHESIS Two reviewers independently screened the retrieved citations and extracted data. The risk of bias and applicability of results were assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Narrative data synthesis was performed. RESULTS A total of 1658 citations were screened, and 28 full-text articles were assessed. Nine studies met the inclusion criteria. The reported sensitivity and specificity of stool culture varied between 21.4% and 63.9%, and 61.5% and 100%, respectively. In stool smear microscopy, sensitivities and specificities ranged from 12.1% to 53.9%, and from 79.5% to 100%, respectively. The reported sensitivities of PCR assays, including Xpert assays, ranged from 69.7% to 100%, with specificities ranging from 69.8% to 100%. Most of the studies had a low risk of bias and a low applicability concern in all domains. CONCLUSION This systematic review could not conclude on the diagnostic accuracy of stool specimens for PTB diagnosis in adults. Further studies are required to evaluate the accuracy of stool specimens in adults to enable meta-analyses in updates of this review as well as other systematic reviews.

Abstract
In recent years, transcriptomics has enabled us to gain a deeper understanding of fundamental reproductive physiology, including the menstrual cycle, through a more precise molecular analysis. The endometrial mRNA transcript levels fluctuate during the normal menstrual cycle, indicating changes in the relative recruitment and abundance of inflammatory cells, as well as changes in the receptivity and remodeling of the endometrium. In addition to providing a more comprehensive understanding of the molecular underpinnings of pathological gynecological conditions such as endometriosis, leiomyomas, and adenomyosis through RNA sequencing, this has allowed researchers to create transcriptome profiles during both normal menstrual cycles and pathological gynecological conditions. Such insights could potentially lead to more targeted and personalized therapies for benign gynecological conditions. Here, we provide an overview of recent advances in transcriptome analysis of normal and pathological endometrium.

Abstract
Over 19 million people worldwide were diagnosed with cancer in 2020. Informal caregivers of adults with cancer play an important role in helping their loved ones with cancer yet often receive little support in developing the necessary skills for caregiving. A systematic review of skill-building interventions for informal caregivers of adults with cancer was conducted across three electronic databases for academic articles published through February 2022. PRISMA reporting guidelines were followed throughout this review, the Mixed Methods Appraisal Tool was used to assess study quality, and results were summarized in a narrative synthesis. The main components of skill-building interventions examined include caregiving preparedness, communication, and self-care. Nine of the 11 included articles showed that interventions effectively built skills for informal caregivers. The articles reviewed had a wide variety of intervention strategies, outcome measures, and study designs. Two of the 11 articles mentioned vulnerable and key groups, and no studies were performed in low- and middle-income countries. Findings generally support implementing skill-building interventions for informal caregivers of adults with cancer; however, further research is necessary to determine the most effective approaches for improving caregiver skills and reaching vulnerable and key populations.

Abstract
In the last few decades, our understanding of the complex pathobiology of uterine fibroid development has grown. While previously believed to be a purely neoplastic entity, we now understand that uterine fibroids possess different and equally important aspects of their genesis. An increasing body of evidence suggests that oxidative stress, the imbalance between pro- and antioxidants, is an important factor in fibroid development. Oxidative stress is controlled by multiple, interconnecting cascades, including angiogenesis, hypoxia, and dietary factors. Oxidative stress in turn influences fibroid development through genetic, epigenetic, and profibrotic mechanisms. This unique aspect of fibroid pathobiology has introduced several clinical implications, both diagnostic and therapeutic, that can aid us in managing these debilitating tumors by using biomarkers as well as dietary and pharmaceutical antioxidants for diagnosis and treatment. This review strives to summarize and add to the current evidence revealing the relationship between oxidative stress and uterine fibroids by elucidating the proposed mechanisms and clinical implications.

Abstract
In this article, we have reviewed how the women of Bangladesh are negatively exposed to the COVID-19 pandemic in terms of quality education, employment loss, labour market contribution, domestic violence, and health and wellness, thus putting their lives at more significant risk. We have employed the Drivers-Pressures-States-Impact-Response (DPSIR) framework to analyze the gendered effects of COVID-19 on some specific Sustainable Development Goals (SDGs) in Bangladesh. We have purposively selected five SDGs, SDG 1 (no poverty), SDG 3 (good health and well-being), SDG 4 (quality education), SDG 5 (gender equality), and SDG 8 (decent work & economic growth), those have direct effects on women's livelihood and well-being. Our DPSIR framework analysis has shown that gendered vulnerabilities have been exacerbated due to the COVID-19 situation with multiple pre-existing socio-cultural norms and various state policies like patriarchal values, stay-home policies etc. As SDG 1 focuses on poverty reduction, and SDG 8 focuses on decent work and economic growth, unemployment, losing job opportunities and economic downturn due to the pandemic have slowed down national growth as well as increased poverty in the country. With excessive pressure on the health sector to deal with COVID-19, women’s essential maternal, sexual and reproductive health (SRH) services were neglected and health disparities were also observed. Thus, many women and adolescent girls could not access SRH services when needed that led to a myriad of consequences for SDG 3 achievements. The prolonged shutdown of educational institutes resulted in mass school dropouts, mental health problems, and higher risks of child labour and child marriage among girl children which has significant negative impacts on the achievement of SDG 4. Due to COVID-19-related preventive measures, such as social distancing, and lockdown, women have been involved to do more care and household job following traditional gender roles, experienced work from home, and a ‘shadow pandemic’ domestic violence amidst the COVID-19. Consequently, the overall gender gap has increased (SDG 5). We have argued that the existing neoliberal market economy has failed to save the global society from a pandemic, therefore, it is important to rethink its development targets and indicators. Moreover, a paradigm shift is recommended by deconstructing present economic systems to build a resilient society based on the caring relationships among nature, humans, and society embracing an ecofeminist perspective.

Abstract
Although microplastic (MP) pollution of aquatic ecosystems is a high-priority study topic, the issue of terrestrial environment and textile manufacturing waste has received little attention. Thus, this study was carried out to investigate the presence of MPs in agricultural land near textile industries and textile sludge samples in Bangladesh. Thirty-two soil samples from four agricultural farmland and five sludge samples were collected and analyzed. We show that the MPs content from agricultural farmland soil and textile sludge samples was 2.13 × 104 ± 0.13 × 104 MPs/kg and 2.92 × 104 ± 0.14 × 104 MPs/kg, respectively. MPs with a size between 1.0 and 1.5 mm were the least frequent in both soil and textile sludge samples. Fibers were more prevalent in textile sludge and fragments in soil samples. In addition, the percentage of transparent/white MPs was higher in the soil samples, and those classified as "multicolor" and "others" were more frequent in the sludge samples. Nine types of polymers were identified in the soil samples: PS, EVA, latex, HDPE, PVC, ABS, CA, LDPE, and PP. Except for LDPE, all these polymers were also found in the textile sludge samples, in addition to PU, nylon, and FEP, totaling eleven polymer types. On the other hand, we did not find evidence to support the association between MP contamination in soil samples and MPs identified in textile sludge samples. As demonstrated in the principal components analysis (PCA), the analyzed samples were separated by PC1, which suggests that the MPs reported in the soil come from sources that are not directly related to the textile industries. Thus, further research is needed to fully reveal MPs' fate and ecological risks in the soil environment and textile sludge, and necessary action is required to control MP pollution in terrestrial ecosystems.

Abstract
Uterine leiomyomas are the most common benign tumors of the female reproductive system. Obese individuals have a higher burden of uterine leiomyoma, yet the mechanism relating obesity and leiomyoma development remains unknown. In this study, we observe the effect of adipocyte coculture and leptin treatment on human myometrium and leiomyoma cells. We isolated primary leiomyoma and myometrium cells from hysterectomy or myomectomy patients. Protein expression levels of phosphorylated ERK1/2/total ERK1/2, phosphorylated STAT3/total STAT3, and phosphorylated AKT1/2/3/total AKT1/2/3 were quantified using immunoblotting in immortalized and primary leiomyoma and myometrial cells cocultured with human adipocytes and treated with leptin. An enzyme-linked immunosorbent assay (ELISA) was used to assess pro-inflammatory, fibrotic, and angiogenic factors in immortalized human myometrium and leiomyoma cells treated with leptin. The effects of STAT3, ERK, and AKT inhibitors were assessed in leiomyoma cell lines additionally cultured with adipocytes. Adipocyte coculture and leptin treatment increases the expression of JAK2/STAT3, MAPK/ERK, and PI3K/AKT signaling while inhibitors suppressed this effect. Leptin induces a tumor-friendly microenvironment through upregulation of pro-inflammatory (IFNγ, IL-8, IL-6, GM-CSF, MCP-1, and TNF-α), fibrotic (TGF-β1, TGF-β2, and TGF-β3), and angiogenic (VEGF-A, HGF, and Follistatin) factors in human leiomyoma cells. Furthermore, adipocyte coculture and leptin treatment increases leiomyoma cells growth through activation of MAPK/ERK, JAK2/STAT3, and PI3k/AKT signaling pathways. Finally, STAT3, ERK, and AKT inhibitor treatment suppressed PCNA, TNF-α, TGF-β3, and VEGF-A intracellular staining intensity in both adipocyte coculture and leptin treated leiomyoma cells. These findings suggest that, in obese women, adipocyte secreted hormone or adipocytes may contribute to leiomyoma development and growth by activating leptin receptor signaling pathways.

Abstract
OBJECTIVE Obesity and its consequences are among the biggest challenges facing the healthcare system. Uterine leiomyomas are the most common gynecologic tumors. The risk of leiomyoma increases with obesity, but the underlying mechanisms of this association remain unclear. The aim of the present study to determine the cellular and molecular mechanisms by which adipocyte contributes to both leiomyoma tumor initiation and promotion. METHODS Primary myometrium and leiomyoma cells were isolated from patients who underwent a hysterectomy or myomectomy. Pro-inflammatory, fibrotic, and angiogenic factors were measured using a multiplex cytokine array in human primary and immortalized myometrial and leiomyoma cells cocultured with human adipocyte (SW872) cells, or in animal ELT3 leiomyoma cells cocultured with 3 T3-L1 adipocytes. The free fatty acids (FFAs) and fatty acid-binding protein 4 (FABP4) levels were measured using immunofluorescence assays. Other protein abundances were determined using western blots. The expression levels of TNF-α, MCP-1, phospho-NF-κB, TGFβ3 and VEGF-A in lean and obese in different leiomyoma patients were determined by immunofluorescence staining. RESULTS Adipocytes promote inflammation, fibrosis, and angiogenesis in uterine leiomyoma cells by upregulating associated factors, such as IL-1β, TNF-α, MCP-1, GM-CSF, TGF-βs, PLGF, VEGF, HB-EGF, G-CSF and FGF2. Coculture led to the transfer of FFAs and FABP4 from adipocytes to leiomyoma cells, suggesting that adipocytes may modulate metabolic activity in these tumor cells. Increased levels of FFA and FABP4 expressions were detected in obese leiomyoma tissue compared to lean. The adipocyte-leiomyoma cell interaction increased the phospho-NF-κB level, which plays a key role in inflammation, restructuring metabolic pathways, and angiogenesis. Obese leiomyoma patients expressed a higher amount of TNF-α, MCP-1, phospho-NF-κB, TGFβ3 and VEGF-A than lean leiomyoma patients, consistent with in vitro findings. Furthermore, we found that adipocyte secretory factors enhance leiomyoma cell proliferation by increasing PCNA abundance. Finally, the inhibition of the inflammatory factors TNF-α, MCP-1, and NF-κB abrogated the adipocyte coculture-induced proliferation of leiomyoma cells. CONCLUSIONS Adipocytes release inflammatory, fibrotic, and angiogenic factors, along with FFAs, which contribute to a tumor-friendly microenvironment that may promote leiomyoma growth and can represent a new target for leiomyoma prevention and treatment.

Abstract
INTRODUCTION Immunization campaigns and Expanded Program on Immunization (EPI) were launched by Government of Bangladesh (GoB) in collaboration with WHO and other Non-governmental Organizations (NGOs) to tackle the increased risk of vaccine preventable disease outbreak in the Rohingya refugee camps. Immunization coverage was found to be lower than expected. However, a few studies explored the factors behind low vaccine uptake among Refugee children. Therefore, this study was aimed. METHODS A cross sectional study was carried out among Rohingya parents living in registered camps and makeshift settlements located in Teknaf and Ukhiya upazilla of Cox's Bazar, Bangladesh. A total of 224 Rohingya parents were conveniently selected (122 parents from each type of camps). Data was collected using a pretested interviewer-administered semi-structured questionnaire with the help of bilingual volunteers who understand Rohingya dialect. All statistical analyses were carried out in IBM SPSS Version 26 (New York, USA). RESULTS Total 63.1% of Rohingya parents had good practice regarding childhood immunization (completed EPI vaccination) as per schedule. Of all, 74.6% had good knowledge and 94.7% had positive attitude towards EPI vaccination. Good practice regarding vaccination was significantly more common among parents living in registered camps (77%) than those living in makeshift settlements (49.2%, p<0.001). Multivariable logistic regression analysis revealed that living in registered camps (Adjusted Odds Ratio [aOR]: 2.99; 95% Confidence Interval [CI]: 1.41-6.32) and good knowledge level (aOR: 2.88; 95%CI: 1.32-15.82) were independent determinants of good practice. A separate analysis in both type of camps revealed that in registered camps, good knowledge level (aOR: 3.62; 95%CI: 1.45-9.04) and having >2 children (aOR: 3.71; 95%CI: 1.34-10.27), and in makeshift settlements, father's employment (aOR: 2.33; 95%CI: 1.34-6.72), father's education (aOR: 3.00; 95%CI: 1.34-6.72) and presence of any electronic device (e.g., radio, television, mobile phone) (aOR: 4.01; 95%CI: 0.96-16.84) were significant determinants of good childhood immunization practice. CONCLUSION Health education and promotion strategies should be implemented to increase knowledge and awareness about EPI immunization benefits among Rohingya parents to ensure greater coverage.

Abstract
OBJECTIVE To investigate the molecular effects of leptin on uterine leiomyoma cells. DESIGN Experimental study using in vitro culture of immortalized human leiomyoma (HuLM) cells. SETTING Academic university center. PATIENT(S) Women with uterine fibroids who underwent a hysterectomy or myomectomy. INTERVENTION(S) Administration of human recombinant leptin to the media of cultured HuLM cells separately or in combination with pharmacologic Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) or mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) inhibitors. MAIN OUTCOME MEASURE(S) We examined HuLM tissues and cells for the expression of the leptin receptor, termed OB-R. Cellular proliferation was measured at 6, 24, and 48 hours using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay. Protein expression levels of proliferating cell nuclear antigen, collagen 1, phosphorylated STAT3/total STAT3, and phosphorylated ERK1/2 and total ERK1/2 were quantified using immunoblotting. Pharmacologic inhibitors were employed to further assess the role of the JAK2/STAT3 and MAPK/ERK pathways in the proliferative response. RESULT(S) The presence of OB-R was confirmed in clinical leiomyoma and myometrial tissue obtained from 3 separate human subjects using immunofluorescence staining, and the expression of OB-R in HuLM cells was identified using immunoblotting. There was no significant difference in the expression of the leptin receptor in the myometrium compared with that in the leiomyoma tissue. Leptin stimulated cell proliferation and extracellular matrix (ECM) deposition at 24 hours after treatment. Pretreatment with a JAK2/STAT3 inhibitor attenuated ECM deposition, and pretreatment with a MAPK/ERK inhibitor significantly decreased leptin's stimulatory effect on cell proliferation and ECM deposition. CONCLUSION(S) Leptin induces a proliferative response and ECM deposition in HuLM cells. These findings suggest that leptin, acting through the JAK2/STAT3 and MAPK/ERK pathways, is involved in the development of uterine leiomyomas, which may partly explain their increased incidence in obese women.

Abstract
BACKGROUND Thiopurine-related adverse events such as leukopenia, liver dysfunction and pancreatitis are associated with variants in the NUDT15 gene. Loss-of-function (low or no enzyme activity) alleles are more common in Asian and Hispanic populations. The prevalence of these variants in the Australian inflammatory bowel disease (IBD) population has not yet been reported. AIM To evaluate the presence of NUDT15 loss-of-function alleles *2,*3,*9 in the Australian IBD population. METHODS The NUDT15 screening cohort included 423 IBD patients from Brisbane, Australia. Study patients were recruited by: (i) retrospective review of clinical charts for thiopurine-related severe adverse events; (ii) pathology data (white blood cell (WBC) and neutrophil counts). NUDT15 genotyping was performed using polymerase chain reaction (PCR)-high-resolution melt (HRM), TaqMan genotyping and Sanger sequencing. RESULTS NUDT15 mutation R139C (allele *3) was identified in 8 of 423 (1.9%) IBD patients. Seven of eight patients were R139C heterozygous (C/T) and one patient was R139C homozygous (T/T). One of the C/T group and the T/T patient developed thiopurine-induced myelosuppression (TIM) within 60 days of dosing. One patient in the C/T group developed TIM after 60 days of thiopurine dosing. The remaining five patients in the C/T group did not show TIM; however, other thiopurine-related events could not be ruled out and therefore careful monitoring over a long period is recommended. CONCLUSIONS This is the first study to report the frequency of NUDT15 haplotypes *2,*3,*9 in an Australian IBD population. The most common variant detected was the R139C mutation. PCR and Sanger sequencing are efficient and cost-effective approaches for NUDT15 genotyping.

Abstract
Celebrities, athletes and even politicians are frequently identified as role models for most impressionable students. But the reality is, outside of their own home, one of the greatest role models in a student's life is standing in front of the classroom. Teachers are people to look up to and emulate. This paper attempts to discover some of the essential qualities and skills that would help teachers and the students they teach achieve their full potentials, and also some key characteristics that contribute to teachers and instruction effectiveness. This paper also attempts to highlight the features of 3H (Head, Heart and Hands) model in effective instructional approach and theorizes that the 3H attributes in combination with Bloom's Taxonomy will produce effective 21st century teachers. Hence, this article endeavors to create awareness and contribute to the transformation of teachers toward reflective and visionary; confident and competent teachers. After all, effective teachers will inspire their talented students to live up to their full potentials. Effective 21st century teachers are in the best position to shape and equip students with the desired 21st century skills.

Abstract
OBJECTIVE Memory impairment is a serious problem that has a significant negative impact on survival and quality of life. When used for a long time, drugs used to treat memory loss become less effective and have more side effects, making therapy more difficult. Different medicinal plants are now being highlighted because of their valuable applications and low risk of adverse effects. Moringa oleifera is one of these plants that has gained much attention due to its diverse biological functions. The study aimed to determine the effects of Moringa oleifera on working memory in memory-impaired Wistar rats. RESULTS For this experimental study, 30 male Wistar rats having 150-250 g bodyweight were divided equally into three groups: Group-I/normal memory group (treated with oral normal saline 5 ml/kg body weight), Group-II/memory-impaired group (induced by intraperitoneal ketamine 15 mg/kg body weight), and Group-III/experimental group (treated with oral Moringa oleifera 200 mg/kg bodyweight and intraperitoneal ketamine 15 mg/kg body weight). The experimental group showed significantly fewer working memory errors than the memory-impaired group. The experimental group also provides the lowest variability of WMEs among groups. Thus, the study concludes that M. oleifera can prevent ketamine-induced memory impairment in Wistar rats.

Abstract
The emerging concept of planetary health needs to be discussed in a more organized and sustainable way within the global public health and healthcare disciplines. Therefore, planetary health should be considered a cardinal component of the global academic framework for healthcare professionals. The availability of related curricula and courses is crucial to equip health professionals in this relatively new discipline of planetary health. In this review article, we aimed to explore published articles and online databases of courses to summarize the available planetary health education opportunities and discussions for health professionals, to identify the gaps in resource allocation and to suggest future recommendations. We observed a visible resource inequity in the global south with the lack of a universal planetary health module for healthcare professionals. Additionally, there is minimal inclusion of allied health disciplines in this learning process. We therefore recommend a dedicated network of motivated healthcare professionals and regional hubs with an agenda to ensure a comprehensive, uniform, and inclusive planetary health education curriculum and practice.

Abstract
Microplastic pollution is a global concern, mainly due to its adverse effects on organisms and ecosystems. However, our knowledge of its impact on humans, in particular, is still very limited. Thus, while we have not gathered definitive information on their consequences, studies that aim to identify the MP's sources constitute subsidies to better understand the various exposure pathways to these pollutants. Thus, we investigated the possible presence of MP-like particles in teabag samples (of different brands) obtained in Dhaka, Bangladesh. Surprisingly, all analyzed samples (five brands) were contaminated with MPs. Fragments and fibers were identified in a higher percentage, and a wide variety of colors was identified, with a predominance of brown, blue, and red colors. Scanning electron microscope images of teabags exhibited net-like structures of fiber particles with a smooth surface. Furthermore, we observed irregularly shaped MPs and rougher surfaces and fragments in the process of detachment from the main fiber, oxidation flakes, and fracture-like. The average size of these pollutants was between 200.6 and 220.7 μm, and the polymer types identified via Fourier-transform infrared spectroscopy (FT-IR) were polytetrafluoroethylene, high-density polyethylene, polycarbonate, nylon, polyvinyl chloride, polytetrafluoroethylene, ethylene-vinyl acetate, cellulose acetate, and acrylonitrile butadiene styrene, the last three being the most frequent in the analyzed samples. Finally, we noticed that MPs from tea bags in Dhaka could cause an average emission of 10.9 million grams of MPs/year. Although the teabags analyzed in our study are not "complemented with the appealing flavor of MPs", it is very likely that tea ingestion in Dhaka is accompanied by the concomitant ingestion of plastic particles making teabags an important route of human exposure to these micropollutants.

Abstract
Although several studies are confirming the ubiquity of microplastics (MPs) in environments, our knowledge about their effects on human health is still very limited. Therefore, while we have not gathered definitive information on their consequences, studies that aim to identify the MPs sources constitute subsidies to better understand the various exposure pathways to these pollutants. Thus, we investigated the possible presence of MP-like particles in five brands of commercial sugars and two unpacked, unbranded, and unlabeled sugars (hereinafter referred to as "non-branded"), obtained from different supermarkets in Dhaka (Bangladesh). Surprisingly, MPs-like particles were identified in all analyzed samples and taken together, our data demonstrated similar variations (between branded and non-branded samples) in terms of number, size, shape, color, and polymer composition. The number of plastic particles/kg sugar was, on average, 343.7 ± 32.08 (mean ± SEM), having been observed a tendency for a higher frequency of MPs < 300 μm. Overall, microfibers and spherules were the most and the predominant colors of MPs (in general) were black, pink, blue, and brown. The FT-IR analysis confirmed the chemical nature of MPs (in branded and non-branded), having identified nine polymeric types (ABS, PCV, PET, EVA, CA, PTFE, HDPE, PC, and nylon), being ABS and PVC the most frequent. Furthermore, we estimate that sugar consumption in Dhaka City can cause the ingestion of millions of tons of MPs annually (2.4 to 25.6 tons) (with an average of 10.2 tons). Our study is the most comprehensive report on the MP's occurrence in sugar, confirming that the ingestion of this food constitutes an important route of human exposure to these micropollutants and, therefore, serves as a baseline for future assessments and useful for generating efficient strategies to control MPs.

Abstract
Uterine leiomyomas are complex tumours with limited medical treatment options. Simvastatin is used to treat hypercholesterolaemia and has shown promising effects as a treatment option for leiomyomas. Previously, our group demonstrated a promising effect of simvastatin treatment in a patient-derived xenograft mouse model. Here, we tested the efficacy of simvastatin liposomal nanoparticles (NPs). After bilateral leiomyoma xenograft implantation, mice (N = 12) were divided into three treatment arms: control, simvastatin and simvastatin-loaded liposome NPs (simvastatin-NPs). Treatment with simvastatin significantly reduced tumour volume and inhibited the Ki67 expression when compared to the control group. There was a trend of reduced tumour volume and Ki67 expression after treatment with simvastatin-NP; however, the results were not significant. Due to low bioavailability and short half-life of simvastatin, liposomal NPs have the potential to enhance drug delivery, however, in this study NP did not provide improvement over simvastatin, but did demonstrate their potential for the delivery of simvastatin.Impact statementWhat is already known on this subject? Simvastatin treatment in a patient-derived xenograft mouse model reduced tumour growth and decreased proliferation.What do the results of this study add? Treatment with simvastatin significantly reduced tumour volume and inhibited the Ki67 expression when compared to the control group. There was a trend of reduced tumour volume and Ki67 expression after treatment with simvastatin-NP, however, it did not improve the efficacy of simvastatin at reducing tumour growth and proliferation.What are the implications of these findings for clinical practice and/or further research? More studies are needed to optimise the formulation of NPs to further enhance the sustainable delivery of simvastatin.

Abstract
INTRODUCTION Environmental toxicants such as chemical pollution have an enormous impact on the health of people and the planet. Emerging findings suggest that non-communicable diseases are linked to early and chronic environmental exposures. However, the rapid globalisation in developing countries, environmental change and the emergence, spread, persistence and severity of infectious diseases are not yet well understood. The aim of this study is to understand which environmental toxicants are commonly associated with infectious diseases in low-income and middle-income countries (LMICs). METHODS AND ANALYSIS A total of four electronic databases, MEDLINE through PubMed, Scopus, Web of Science and CENTRAL (the Cochrane Library) be searched to identify relevant studies and will be screened by two independent reviewers. The Cochrane risk of bias (ROB) tool for randomised control trials (RCTs) and ROB assessment tool for non-randomised studies for non-RCTs will be used to assess the ROB. A meta-analysis will be used to determine the pooled effect if we find out the included articles have similar environmental exposure, participant groups, study design and outcome measures. A narrative synthesis of the findings will be provided, along with summaries of the intervention effect. Heterogeneity between the studies will be assessed, and sensitivity analysis will be conducted based on study quality. ETHICS AND DISSEMINATION Findings will be summarised in a single manuscript. This review attempts to explore the pivotal role of environmental toxicants in predisposing, developing, persistent and severity of infectious diseases in LMICs. Findings from this study will highlight the effects of individual environmental toxicants' role on infectious disease outcomes for the early prevention and limit toxic exposure to guide individual, community, and occupational health policy for future strategies.

Abstract
AIMS Uterine leiomyomas, or fibroids, are estrogen dependent benign tumor in women, however, they have limited treatment options. Simvastatin, a drug commonly used to treat high cholesterol. Recently we demonstrated that simvastatin alters estrogen signaling by reducing the expression and trafficking of the estrogen receptor-α (ER-α) in human uterine leiomyoma cells. Caveolae are invaginations of the plasma membrane where ER-α is known to localize and directly interacts with the caveolar protein caveolin-1 (CAV1). This study examines the effects of simvastatin on plasma membrane caveolae and the expression and palmitoylation of CAV1 in human leiomyomas which may influence ER-α signaling. MAIN METHODS We performed in vitro experiments using primary and immortalized human uterine leiomyoma cells. The caveolae were quantified using transmission electron microscopy. Additionally, we examined the impact of simvastatin treatment (40 mg orally per day for 12 weeks) on human leiomyoma tissue obtained from a randomized controlled trial. The CAV1 protein and mRNA levels were determined using quantitative real-time polymerase chain reactions, western blotting, and immunofluorescence analyses. KEY FINDINGS Simvastatin decreased the number of caveolae in primary leiomyoma cells and reduced CAV1 abundance in whole cells and remarkably the plasma protein fraction. It also decreased CAV1 palmitoylation, a post-translational modification associated with CAV1 activation. The effects of simvastatin on CAV1 were recapitulated in human leiomyoma tissue samples. SIGNIFICANCE Our results identify caveolae and CAV1 as novel targets of simvastatin which may contribute to the recently described effects of simvastatin on ER-α signaling and plasma membrane trafficking.

Abstract
Background The population's mental and physical health worldwide are currently at risk due to the coronavirus pandemic. We evaluated the mental health status of the adolescents trapped indoors because of the precautionary restrictions and prolonged closure of the educational institutions. Method A cross-sectional study was conducted on adolescents from multiple urban and semi-urban areas of Bangladesh from 22 January to 3 February 2021. A self-reported online questionnaire containing questions regarding sociodemographic factors, home quarantine-related factors and mental health symptoms was distributed to collect data. Descriptive analysis, bivariate and multivariable logistic regressions were performed to measure the association of the variables. Cronbach's alpha was estimated to present the internal consistency of the scales. Results A total of 322 adolescents (aged 12–19) with a mean age of 16.00 years (SD = 1.84) responded to the invitation. 54.97% (n = 177) of them were male, and the participants were predominantly urban residents (87.27%, n = 281). We observed varying degrees of depression in 67.08%, anxiety in 49.38% and stress in 40.68% of the participants according to DASS-21. Age, sex, education, mother's occupation, total monthly income, playing sports, doing household chores, going out of home, watching television, using the internet, attending online classes, changing food habits, and communicating with friends had a positive significant association with mental health burdens. Conclusion Home quarantine has a noticeable adverse impact on the mental health of teenagers. Psychological evaluations and counselling via online and offline programs are essential to improve adolescents' declining mental health conditions.

Abstract
Almost all low- and middle-income countries (LMICs) have instated a program to control and manage non-communicable diseases (NCDs). Population screening is an integral component of this strategy and requires a substantial chunk of investment. Therefore, testing the screening program for economic along with clinical effectiveness is essential. There is significant proof of the benefits of incorporating economic evidence in health decision-making globally, although evidence from LMICs in NCD prevention is scanty. This systematic review aims to consolidate and synthesize economic evidence of screening programs for cardiovascular diseases (CVD) and diabetes from LMICs. The study protocol is registered on PROSPERO (CRD42021275806). The review includes articles from English and Chinese languages. An initial search retrieved a total of 2,644 potentially relevant publications. Finally, 15 articles (13 English and 2 Chinese reports) were included and scrutinized in detail. We found 6 economic evaluations of interventions targeting cardiovascular diseases, 5 evaluations of diabetes interventions, and 4 were combined interventions, i.e., screening of diabetes and cardiovascular diseases. The study showcases numerous innovative screening programs that have been piloted, such as using mobile technology for screening, integrating non-communicable disease screening with existing communicable disease screening programs, and using community health workers for screening. Our review reveals that context is of utmost importance while considering any intervention, i.e., depending on the available resources, cost-effectiveness may vary—screening programs can be made universal or targeted just for the high-risk population.

Abstract
INTRODUCTION Urinary tract infection (UTI) is a frequently diagnosed infection in women and children. Treatments are often initiated with broad-spectrum antibiotics without performing any culture and sensitivity test. Inappropriate and empirical antimicrobial regimens and poor adherence to the drugs lead to the recurrence of the disease. Moreover, resistance against antibiotics in the urinary tract bacteria due to inadequate therapies is a more significant cause of concern. This systematic review will explore the different antimicrobial options for treating UTIs in children and compare their effectiveness. METHODS AND ANALYSIS Four electronic databases MEDLINE, Cochrane Central Register of Controlled Trials, Scopus and Web of Science will be searched in February 2022 to find relevant studies. After the initial screening by two independent review authors, the selected articles will go through the full-text evaluation to filter the inclusion criteria. Using an appropriate tool, the risk of bias will also be assessed by two independent review authors. The review results showing the treatment effects of different antimicrobials will be presented as a narrative synthesis, and a meta-analysis will be conducted if applicable. Assessment of heterogeneity between studies, assessment of publication bias, and sensitivity analysis will also be performed. ETHICS AND DISSEMINATION The study protocol of this systematic review has been approved by the institutional review board of North South University. The dissemination of the results will be conducted in the form of scientific publication in a peer-reviewed journal and presentations in different regional and international conferences.

Abstract
Uterine leiomyoma (UL) is the most common gynaecologic tumour, affecting an estimated 70 to 80% of women. Leiomyomas develop from the transformation of myometrial stem cells into leiomyoma stem (or tumour-initiating) cells. These cells undergo self-renewal and differentiation to mature cells, both are necessary for the maintenance of tumour stem cell niche and tumour growth, respectively. Wnt/β-catenin and TGF-β/SMAD pathways, both overactive in UL, promote stem cell self-renewal, crosstalk between stem and mature cells, cellular proliferation, extracellular matrix (ECM) accumulation and drive overall UL growth. Recent evidence suggests that simvastatin, an antihyperlipidemic drug, may have anti-leiomyoma properties. Herein, we investigated the effects of simvastatin on UL stem cells. We isolated leiomyoma stem cells by flow cytometry using DyeCycle Violet staining and Stro-1/CD44 surface markers. We found that simvastatin inhibits proliferation and induces apoptosis in UL stem cells. In addition, it also suppressed the expression of the stemness markers Nanog, Oct4 and Sox2. Simvastatin significantly decreased the production of the key ECM proteins, collagen 1 and fibronectin. Finally, it inhibited genes and/or proteins expression of TGF-β1, 2 and 3, SMAD2, SMAD4, Wnt4, β-Catenin, LRP6, AXIN2 and Cyclin D1 in UL stem cells, all are key drivers of the TGF-β3/SMAD2 and Wnt4/β-Catenin pathways. Thus, we have identified a novel stem cell-targeting anti-leiomyoma simvastatin effect. Further studies are needed to replicate these findings in vivo.

Abstract
AIMS Recent evidence suggests that repetitive hypoxia occurs during menstrual cycles due to vasoconstriction and myometrial contraction. It is unknown if hypoxia contributes to the development of uterine leiomyoma, the most common tumor of the female reproductive system. This study aims to characterize the response to hypoxia in leiomyoma and myometrial cells; and determine if an aberrant leiomyoma response to hypoxia may contribute to leiomyomatogenesis. MAIN METHODS Primary and immortalized leiomyoma and myometrial cells were cultured under normoxic and hypoxic conditions. Expression levels of vascular endothelial growth factor-A (VEGF-A), adrenomedullin (ADM), endothelin-1 (ET-1), and hypoxia-inducible factor-1 alpha (HIF-1α) were measured by qRT-PCR, western blotting and ELISA. Cell proliferation was assessed using MTT assay and proliferating-cell-nuclear-antigen (PCNA) expression. KC7F2 (HIF-1α inhibitor) was used to examine the regulating mechanisms. KEY FINDINGS As expected, hypoxia induced HIF-1α expression in both leiomyoma and myometrial cells. However, hypoxia induced VEGF-A, ET-1 and ADM expression and VEGF-A secretion into the culture media in leiomyoma but not myometrial cells. MTT assay and PCNA expression showed that hypoxia induces proliferation in leiomyoma, but not myometrial cells. HIF-1α inhibitor abrogated the hypoxia-induced VEGF-A, ET-1, ADM, and PCNA expression in leiomyoma cells. SIGNIFICANCE This study suggests an aberrant leiomyoma cellular response to hypoxia compared to myometrium. This differential response to menstruation-related repetitive hypoxia episodes may lead to selective proliferation of hypoxia-adaptive leiomyoma cells and contribute to leiomyoma growth. Thus, in addition to adding to our understanding of leiomyoma pathobiology, the study proposes angiogenic factors as a potential leiomyoma therapeutic target.

Abstract
Uterine leiomyomas, the most common tumors of the female reproductive system, are known to have a hypoxic microenvironment. However, the role of such environment in leiomyoma pathobiology remains unknown. The objective was to determine the effects of hypoxia on leiomyoma cells, and the mechanisms. We found that hypoxia induces proliferation and inhibits apoptosis in human leiomyoma cells. This pro-proliferative effect was accompanied by an increase in reactive oxygen species (ROS) generation and the expression of NADPH oxidase 4 (NOX4). The specific NOX4 inhibitor GLX351322 abrogated this hypoxia-induced ROS generation, cellular proliferation, and apoptosis inhibition. To further investigate the mechanism of NOX4-mediated proliferation, we treated leiomyoma cells grown in normoxia with media from leiomyoma cells cultured under hypoxia. This resulted in increased ROS generation and NOX4 expression, suggesting the hypoxia-induced effects are mediated by an autocrine mechanism. We worked to identify the nature of this autocrine factor. We found that the expression of TGF-β3 and its downstream signaling target pSmad3, are increased in hypoxic leiomyoma cells. To examine the hypothesis that TGF-β3 is, at least, a part of this autocrine mechanism, we treated hypoxic leiomyoma cells with the HIF-1α inhibitor KC7F2 which we discovered to ameliorate the hypoxia-induced TGF-β3 expression. Furthermore, pharmacologic inhibition with the TGF-β/Smad inhibitor SB431542 reduced hypoxia-induced NOX4 expression and ROS generation and attenuated cell proliferation. Thus, we have identified a novel mechanism by which hypoxia induces proliferation in leiomyoma cells. This finding adds to our understanding of leiomyoma pathobiology and can help in identifying new therapeutic targets.

Abstract
The Wnt/β-catenin pathway is upregulated in uterine leiomyomas, the most common benign tumors in the female reproductive tract. Simvastatin is an antihyperlipidemic drug, and previous in vitro and in vivo reports showed that it may have therapeutic effects in treating leiomyomas. The objective of this study was to examine the effects of simvastatin on the Wnt/β-catenin signaling pathway in leiomyoma. We treated primary and immortalized human leiomyoma cells with simvastatin and examined its effects using quantitative real-time polymerase chain reaction, Western blotting, and immunocytochemistry. We also examined the effects using human leiomyoma tissues from an ongoing randomized controlled trial in which women with symptomatic leiomyoma received simvastatin (40 mg) or placebo for 3 months prior to their surgery. The results of this study revealed that simvastatin significantly reduced the expression of Wnt4 and its co-receptor LRP5. After simvastatin treatment, levels of total β-catenin and its active form, nonphosphorylated β-catenin, were reduced in both cell types. Additionally, simvastatin reduced the expression of Wnt4 and total β-catenin, as well as nonphosphorylated β-catenin protein expression in response to estrogen and progesterone. Simvastatin also inhibited the expression of c-Myc, a downstream target of the Wnt/β-catenin pathway. The effect of simvastatin on nonphosphorylated-β-catenin, the key regulator of the Wnt/β-catenin pathway, was recapitulated in human leiomyoma tissue. These results suggest that simvastatin may have a beneficial effect on uterine leiomyoma through suppressing the overactive Wnt/β-catenin pathway.

Abstract
Herbal remedies have been used in many cultures for decades to treat illnesses. These medicinal plants have been found to contain various phytochemical compounds that can help to cure mild to severe illnesses. The inadequacies of conventional medicines and their unusual side effects sparked a determined search for alternative natural therapeutic agents. Another reason for this hunt could be the availability and fewer side effects of natural products. T. arjuna is widely used in traditional medicine to alleviate various diseases like relieving pain, ameliorating diabetes, mitigating inflammation, and back-pedaling of depression. In this study, the ethanolic extract of T. arjuna possesses a promising effect on the animal model (p < 0.05/p < 0.01) as an antihyperglycemic, analgesic, anti-inflammatory, and antidepressant agent, but in a dose-dependent manner. The lower dose of T. arjuna was found to be capable of reversing the disturbed physiological state at a significant level (p < 0.05). However, a higher dose of T. arjuna exerts better therapeutic effects for those diseases. This animal study aims to evaluate the anti-diabetic, anti-depressant, and anti-inflammatory properties of T. arjuna compared to conventional marketed drugs. We will perform an in-silico study for active constituents of T. arjuna against their proposed targets and look for the molecular cascade on their claimed pharmacological properties. This study shows that different doses of T. arjuna bark extracts give similar therapeutic responses compared with established marketed drugs in managing hyperglycemia, stress-induced depression, and inflammation. Besides, our docking study reveals that flavonoids and triterpenoid active constituents of T. arjuna play an important role in its usefulness. This study, therefore, scientifically confirmed the traditional use of this medicinal plant in the management of several diseased conditions.

Abstract
Prescribed fire is an essential tool for wildfire risk mitigation and ecosystem restoration in the Southeastern United States. It is also one of the region's largest sources of atmospheric emissions. The public health impacts of prescribed fire smoke, however, remain uncertain. Here, we use digital burn permit records, reduced-complexity air quality modeling, and epidemiological associations between fine particulate matter concentrations and multiple health endpoints to assess the impacts of prescribed burning on public health across Georgia. Additionally, we examine the social vulnerability of populations near high prescribed burning activity using a demographic- and socioeconomic-based index. The analysis identifies spatial clusters of burning activity in the state and finds that areas with intense prescribed fire have levels of social vulnerability that are over 25% higher than the state average. The results also suggest that the impacts of burning in Georgia can potentially include hundreds of annual morbidity and mortality cases associated with smoke pollution. These health impacts are concentrated in areas with higher fractions of low socioeconomic status, elderly, and disabled residents, particularly vulnerable to air pollution. Estimated smoke-related health incidence rates are over 3 times larger than the state average in spatial clusters of intense burning activity, and over 40% larger in spatial clusters of high social vulnerability. Spatial clusters of low social vulnerability experience substantially lower negative health effects from prescribed burning relative to the rest of the state. The health burden of smoke from prescribed burns in the state is comparable to that estimated for other major emission sectors, such as vehicles and industrial combustion. Within spatial clusters of socially-vulnerable populations, the impacts of prescribed fire considerably outweigh those of other emission sectors. These findings call for greater attention to the air quality impacts of prescribed burning in the Southeastern U.S. and the communities most exposed to fire-related smoke.

Abstract
The effluents from textile industries without proper treatment contains a remarkable amount of synthetic dyes which are harmful to the environment and a big challenge globally to degrade it with a eco-friendly way. Conventional methods are extremely energy-consuming, non-effective and generate a toxic sludge impacting the environment. Several microorganisms can be utilized to treat these effluents. The research deals with five bacteria isolated from textile effluent and their consortium for the biodegradation ability of Novacron dyes. The isolates were identified through the Biolog™ identification system and molecular technique. Biodegradation was confirmed by measuring optical density (OD) optimizing conditions (pH 7.0, temperature 37 °C, 10 % inoculums and 100 mg/L dye) under static condition. The isolates started decolourization at 24 h whereas, the consortium started decolourization at 18 h and exhibited a maximum after 72 h. The presence of low molecular weight protein as metabolite supported the biodegradation and non hazardous to environment. This study revealed that these bacteria might have degradation potentials, and research results will help to set up dye removal eco-friendly methods to expose the dye effulents to environment in future.

Abstract
Uterine leiomyomas or fibroids are the most common tumors of the female reproductive tract. Estrogen (E2), a steroid-derived hormone, and its receptors (ERs), particularly ER-α, are important drivers for the development and growth of leiomyomas. We previously demonstrated that simvastatin, a drug used for hyperlipidemia, also possesses anti-leiomyoma properties. The aim of this work is to investigate the impact of simvastatin on ER-α signaling in leiomyoma cells, including its expression, downstream signaling, transcriptional activity, post-translational modification, trafficking and degradation. Primary and immortalized human uterine leiomyoma (HuLM) cells were used for in vitro experiments. Immunodeficient mice xenografted with human leiomyoma tissue explants were used for in vivo studies. Leiomyoma samples were obtained from patients enrolled in an ongoing double-blinded, phase II, randomized controlled trial. Here, we found that simvastatin significantly reduced E2-induced proliferation and PCNA expression. In addition, simvastatin reduced total ER-α expression in leiomyoma cells and altered its subcellular localization by inhibiting its trafficking to the plasma membrane and nucleus. Simvastatin also inhibited E2 downstream signaling, including ERK and AKT pathways, E2/ER transcriptional activity and E2-responsive genes. To explain simvastatin effects on ER-α level and trafficking, we examined its effects on ER-α post-translational processing. We noticed that simvastatin reduced ER-α palmitoylation; a required modification for its stability, trafficking to plasma membrane, and signaling. We also observed an increase in ubiquitin-mediated ER-α degradation. Importantly, we found that the effects of simvastatin on ER-α expression were recapitulated in the xenograft leiomyoma mouse model and human tissues. Thus, our data suggest that simvastatin modulates several E2/ER signaling targets with potential implications in leiomyoma therapy and beyond.
