MicroRNAs (miRNAs) are small non-coding RNA molecules capable of negatively regulating gene expression to control many cellular mechanisms. The miRTarBase database (http://mirtarbase.mbc.nctu.edu.tw/) provides the most current and comprehensive information of experimentally validated miRNA-target interactions. The database was launched in 2010 with data sources for >100 published studies in the identification of miRNA targets, molecular networks of miRNA targets and systems biology, and the current release (2013, version 4) includes significant expansions and enhancements over the initial release (2010, version 1). This article reports the current status of and recent improvements to the database, including (i) a 14-fold increase to miRNA-target interaction entries, (ii) a miRNA-target network, (iii) expression profile of miRNA and its target gene, (iv) miRNA target-associated diseases and (v) additional utilities including an upgrade reminder and an error reporting/user feedback system.

Nephrolithiasis is characterized by calcification of stones in the kidneys from an unknown cause. Animal models demonstrated the functional roles of the transient receptor potential vanilloid member 5 (TRPV5) gene in calcium renal reabsorption and hypercalciuria. Therefore, TRPV5 was suggested to be involved in calcium homeostasis. However, whether genetic polymorphisms of TRPV5 are associated with kidney stone multiplicity or recurrence is unclear. In this study, 365 Taiwanese kidney‐stone patients were recruited. Both biochemical data and DNA samples were collected. Genotyping was performed by a TaqMan allelic discrimination assay. We found that a TRPV5 polymorphism (rs4236480) was observed to be associated with stone multiplicity of calcium nephrolithiasis, as the risk of stone multiplicity was higher in patients with the TT+CT genotype than in patients with the CC genotype (p = 0.0271). In summary, despite the complexity of nephrolithiasis and the potential association of numerous calcium homeostatic absorption/reabsorption factors, TRPV5 plays an important role in the pathogenesis of calcium nephrolithiasis.

Addressing antimicrobial resistance (AMR) stands as a major global health challenge threatening humanity. Resolving this issue can be initiated through emphasizing the significance of AMR education among students in health colleges during their undergraduate studies. Hence, the aim of this study is to assess the pharmacy students’ knowledge, attitudes, and practices regarding antibiotic resistance in 7 Middle Eastern countries. A cross-sectional study was conducted among undergraduate pharmacy students at universities in Egypt, Jordan, Saudi Arabia, Lebanon, the United Arab Emirates, Qatar, and Kuwait between March 2021 and January 2022. The first section of the questionnaire gathered demographic information. The knowledge section comprised 7 questions. Subsequently, the questionnaire explored participants’ attitudes (6 items) and practices (2 items) concerning antibiotic resistance. Mann-Whitney and Kruskal–Wallis tests were used to compare the median knowledge score between different demographic groups. Logistic regression was used to estimate odds ratios, with 95% confidence intervals (CIs) for being more knowledgeable about antibiotic resistance. A 2-sided P < .05 was considered statistically significant. A total of 4265 pharmacy students were involved in this study (Egypt (2249), Jordan (n = 704), Saudi Arabia (n = 531), Lebanon (n = 401), United Araba Emirates (n = 130), Qatar (n = 129), and Kuwait (n = 121)). The median knowledge score for the participating pharmacy students was 5.00 (IQR = 4.00–6.00) out of 7, equals to 71.4% with 4th, and 5th year students and bachelor of pharmacy program students have higher odds of being more knowledgeable about antibiotics resistance compared to other students (P < .05). The majority of the students agreed that antibiotic resistance is increasing, they should be more concerned regarding antibiotic consumption and that government should create more awareness of antibiotic resistance, and that they should have enough knowledge to prevent antibiotic resistance. Around 3 quarters of the students (73.0%) confirmed that they take antibiotic only after getting prescription from their physician and almost half (51.7%) reported that they take antibiotic to manage their fever. The study concluded good educational programs in Middle East pharmacy schools with the need for targeted educational interventions promoting responsible antibiotic stewardship practices among future pharmacists.

Background: According to the International Diabetes Federation (IDF), diabetes is increasing exponentially worldwide and will become more prevalent than ever in the Middle East by 2045, with a 110% increase. This study aims to clarify the role of pharmacists and community pharmacies in the screening, knowledge, and awareness of Type 2 diabetes among Jordanian people who visit community pharmacies in Amman, Jordan. Methods: Study design: This was a cross-sectional prospective study that was conducted from September to December 2021 in Amman, Jordan. Data were collected using a standardized questionnaire that was composed of multiple parts. The first part collected information on demographics, residence, educational level, and insurance status; the second part was composed of 14 knowledge assessing questions; the last part was composed of the American Diabetes Association (ADA) diabetes risk score card test. Additionally, after confirming that each participant had returned their completed sheets, participants who scored greater than 5 had their blood sugar levels checked using a finger-prick blood test. The questionnaire was administered in person by a trained researcher. Using Slovin’s formula, a 95% confidence interval (CI), and a 0.05 margin of error, the sample size was determined to be 267 participants. The study included 305 participants. Descriptive and regression analyses were performed by using the Statistical Package for Social Science (SPSS) with a significance level of p < 0.05. Results: A significant relationship was found between specialty (medical education) and the knowledge of risk factors for Type 2 diabetes mellitus (T2DM), (p < 0.012). In terms of knowledge, from a total of 13 correct knowledge points (13 marks for correct answers out of 14), some subjects scored slightly higher than others (n = 175; 57.4% of participants scored above 7, nearly over half of the correct answers, compared to n = 130; 42.6% scoring below 7). We found 132 individuals (44%) with risk scores of five or above (high risk for developing T2DM according to ADA). Smokers comprised n = 138, 45%, and nonsmokers comprised n = 148, 48%. Although 50.5% of the participants (n = 154) held a bachelor’s, master’s, or doctorate degree, these degrees did not improve the participants’ overall general knowledge levels. The association was tested using chi-squared analysis, but no significance was found. Conclusions: Random visitors to Jordanian community pharmacies are expected to benefit from awareness and educational campaigns. These test results revealed a lack of knowledge, indicating the need for education to dispel myths and highlight the serious risks associated with T2DM. The study discovered that participants’ understanding of diabetes disease prevention through lifestyle and dietary changes was inadequate. A specialist-led educational program may increase knowledge among visitors who participate. In order to prevent the spread of diabetes, more campaigns and health-promoting and prevention educational activities are required.

Type 2 diabetes mellitus is a multifactorial disorder whose primary manifestation usually initiates with elevated blood sugar levels. Several antidiabetic agents are used to manage type 2 diabetes mellitus, of which empagliflozin is an oral sodium-glucose co-transporter (SGLT-2) inhibitor in the kidney. This research aims to develop and validate a simple analytical method for determining empagliflozin levels in biological fluid and to further evaluate grapefruit juice’s impact on empagliflozin pharmacokinetics in rats. High-Performance Liquid Chromatography (HPLC) was used to establish a simple, rapid, and accurate method for determining empagliflozin levels in rat plasma, in the presence of grapefruit juice. Four groups of rats (n = 10 rats in each) were used in the preclinical study. Group A (healthy rats) received empagliflozin alone; Group B (healthy rats) received empagliflozin with grapefruit; Group C (diabetic rats) received empagliflozin with grapefruit; and Group D (healthy, negative control) received no medication. The rats (n = 10) were given grapefruit juice instead of water for seven days before receiving the empagliflozin dose (0.16 mg/kg). Some pharmacokinetic parameters for each group were determined. The maximum plasma concentration (C_max) and area under the curve (AUC) of empagliflozin in Group A without grapefruit intake were 730 ng/mL and 9264.6 ng × h/mL, respectively, with T_max (2 h). In Group B, C_max was 1907 ng/mL and AUC was 10,290.75 ng × h/mL in the presence of grapefruit, with T_max (1 h); whereas, in Group C, the C_max was 2936 ng/mL and AUC was 18657 ng × h/mL, with T_max (2 h). In conclusion, our results showed that the co-administration of grapefruit with empagliflozin should be cautiously monitored and avoided, in which grapefruit elevates the plasma level of empagliflozin. This may be attributed to the inhibition of the uridine enzyme in the grapefruit by hesperidin, naringin, and flavonoid.

Background: Cigarette smoking is the leading preventable cause of death worldwide, and it is the most common cause of oral cancers. This study aims to provide a deeper understanding of the molecular pathways in the oral cavity that are altered by exposure to cigarette smoke. Methods: The gene expression dataset (accession number GSE8987, GPL96) of buccal mucosa samples from smokers (n = 5) and never smokers (n = 5) was downloaded from The National Center for Biotechnology Information's (NCBI) Gene Expression Omnibus (GEO) repository. Differential expression was ascertained via NCBI’s GEO2R software, and Ingenuity Pathway Analysis (IPA) software was used to perform a pathway analysis. Results: A total of 459 genes were found to be significantly differentially expressed in smoker buccal mucosa (p < 0.05). A total of 261 genes were over-expressed while 198 genes were under-expressed. The top canonical pathways predicted by IPA were nitric oxide and reactive oxygen production at macrophages, macrophages/fibroblasts and endothelial cells in rheumatoid arthritis, and thyroid cancer pathways. The IPA upstream analysis predicted that the TP53, APP, SMAD3, and TNF proteins as well as dexamethasone drug would be top transcriptional regulators. Conclusions: IPA highlighted critical pathways of carcinogenesis, mainly nitric oxide and reactive oxygen production at macrophages, and confirmed widespread injury in the buccal mucosa due to exposure to cigarette smoke. Our findings suggest that cigarette smoking significantly impacts gene pathways in the buccal mucosa and may highlight potential targets for treating the effects of cigarette smoking.
