Adaptation of Research Project Requirement at Pharmacy Undergraduate Studies: Students' Perception, Attitude, and Experiences.

Objective: To determine the final year pharmacy undergraduate students' attitudes toward research after completing a research project. Methods: A research project was introduced in the final year of the PharmD program in January 2022. After a period of one year, in Janurary 2023, students submitted their final research to the faculty members. The survey was conducted from 1st March to 30st April 2023 using a study tool that contained items asking students' demographic, their research perceptions, attitude and experience, and also motivation/barriers faced during the research project. Descriptive and t-test statistics were utilized to compare the means of subgroups at a level of significance, i.e., p < 0.05. The data were also analyzed using Goodman and Kruskal's gamma and Mann-Whitney U test. Results: Majority of the students (93.8%) agreed regarding the significance of research in the pharmacy profession. Students were found to have their projects a worthwhile learning opportunity (94.2%). Students' motivation to execute research project stems from mandatory curriculum courses, improving clinical or hospital pharmacist training and fulfilling research skills (90%). Barriers hindered include lack of training, time, and patient follow-up (approximately 70%). Conclusion: The current study's finding was concluded with the fact that research is a valuable component of a well-rounded education and can enhance a pharmacist's skills. However, they need a combination of formal education and practical experience to pursue a profession in pharmacy.

Approaches and perspectives for online learning during the COVID-19 pandemic and future chaos.

BACKGROUND: Online learning (OLL) methodology has been incorporated in higher education extensively on the mount over the last few decades and with the onset of COVID-19 situation, the virtual method in academia became essential. After observing worldly destructions and death due to coronavirus, the WHO declared a high alert emergency, and since Pakistan started to follow lockdown since March 2020 to prevent high penetration and consequently, the online teaching method was adapted to keep the learning atmosphere alive. The study is aimed to identify the influencing factors and compliance for the implementation of the OLL system in COVID-19 and, in the future, nonpandemic state as well. MATERIALS AND METHODS: The present study is designed to observe the adaptability and hurdles among pharmacy students, and for the purpose of the study, a questionnaire on the Likert scale was developed and asked to respond from pharmacy undergraduate and postgraduate students after taking consensus, which further analyzed through IBM SPSS Statistics Version 26. RESULTS: The outcomes of the study were analyzed with a high level of conformity; however, the gender-based reservations were observed, and moreover, merits of OLL were observed with high jeopardy. CONCLUSION: The adaptation of OLL, though proved as the only troubleshooter in an uncontrollable situation and enabled universities, professors, and students for patience, resilience, and hopefully, will serve as swift safeguard for future challenges of epidemic and pandemic disasters. According to the evolution theory, brain adaptability and plasticity of human organisms grow the capacity to adjust itself with an advanced characteristic.

Self-Medication in the COVID-19 Pandemic: Survival of the Fittest.

OBJECTIVE: After the World Health Organization (WHO) declared coronavirus disease 2019 (COVID-19) a pandemic, intense efforts to combat the novel coronavirus were undertaken, with many fatalities in most regions of the world. The high fatality rate and socioeconomic collapse affected the health of uninfected individuals because healthcare measures and scheduled clinical and hospital visits were avoided by people in an attempt to reduce their exposure to the contagion. The general population began self-medication practices as means to safeguard against exposure to the virus. METHODS: The present study investigated the effectiveness of self-medication compliance among the general population. For this purpose, a questionnaire on the Zenodo scale was developed and adults and teen respondents were asked to complete it, after providing consent. The data gathered were analyzed using IBM SPSS Statistics Version 26. RESULTS: The study amazingly found high compliance with self-medication among the focused population during the period of COVID-19. Estimated results showed a highly significant correlation of 0.000, P < 0.05, between the adaptation of self-medication and pandemic situation, which was estimated from chi-squared and Fisher test results. CONCLUSIONS: However, the fear of coronavirus made the practice, or malpractice, a survival of the fittest, innate ability of human nature.

Some novel piperidine analogues having strong alpha glucosidase inhibition.

The idea of this study is based on the marvelous fact of nojirimycin and deoxy nojirimycin, naturally occurring from piperidine class and having their role as alpha glucosidase inhibitors. In the present work some hydroxyl piperidine analogues have been synthesized and analysed for their hypoglycemic effect through glucosidase inhibition owing to the structural resemblance with nojirimycin. The activity was done by spectral absorbance analysis using acarbose as standard. Two analogues (I & IV) were found to pose excellent activity having 87.4 and 54.7% inhibition respectively, hence strengthening the idea of studying piperidine analogiues as glucosidase inhibitors due to structural similarity with nojirimycin.

Prescribing pattern of angiotensin receptor blocker: A study of errors and drug-drug interactions.

Prescriptions comprising multi-drug therapy mostly illustrate the prescribing error. The phenomenon of error is bonded with human inaccuracy. The erroneous practice is observed in under developed countries like Pakistan, Bangladesh and also in developed ones. Consequently drug-drug interaction is one of the most common error associated with potentially serious adverse response even death. Accordingly the present study was conducted to assess the prevalence of prescribing errors and drug-drug interactions in out-patients receiving angiotensin receptor blockers. The study was done with population size one hundred fifty prescriptions obtained from different out-patient settings in Karachi. The prescriptions were screened for prescribing errors and risk factors for drug-drug interactions. Drug-drug interactions were recognized by Micromedex.2.0.Drug-Reax®database. The most common type of error was omission error. These errors were patient's age, weight and diagnosis found in 51.3%, 97.3% and 74% of prescriptions, respectively. The prevalence of drug-drug interaction was 38%. A total of 746 drugs were prescribed with an average of 5 drugs per prescription and 450 medication errors were detected. Majority of the interaction were moderate (19.33%), others were minor (14%) and major (6%) in severity. Patients who prescribed many drugs (more than 5 drugs in a while) had a higher risk of developing drug-drug interactions (OR=4.76; 95% CI=2.30-9.64; p=0.0001*).The study data reports the occurrence of prescribing errors in Karachi and also necessitate the need of clinical pharmacist's services in health care system. The step will help to minimize the risk factors by having the drug prescriptions reviewed by the pharmacists.

CREB mediates the insulinotropic and anti-apoptotic effects of GLP-1 signaling in adult mouse ß-cells.

OBJECTIVE: Glucagon-like peptide-1 (GLP-1) plays a major role in pancreatic ß-cell function and survival by increasing cytoplasmic cAMP levels, which are thought to affect transcription through activation of the basic leucine zipper (bZIP) transcription factor CREB. Here, we test CREB function in the adult ß-cell through inducible gene deletion. METHODS: We employed cell type-specific and inducible gene ablation to determine CREB function in pancreatic ß-cells in mice. RESULTS: By ablating CREB acutely in mature ß-cells in tamoxifen-treated Creb (loxP/loxP);Pdx1-CreERT2 mice, we show that CREB has little impact on ß-cell turnover, in contrast to what had been postulated previously. Rather, CREB is required for GLP-1 to elicit its full effects on stimulating glucose-induced insulin secretion and protection from cytokine-induced apoptosis. Mechanistically, we find that CREB regulates expression of the pro-apoptotic gene p21 (Cdkn1a) in ß-cells, thus demonstrating that CREB is essential to mediating this critical aspect of GLP-1 receptor signaling. CONCLUSIONS: In sum, our studies using conditional gene deletion put into question current notions about the importance of CREB in regulating ß-cell function and mass. However, we reveal an important role for CREB in the ß-cell response to GLP-1 receptor signaling, further validating CREB as a therapeutic target for diabetes.

Genome-wide analysis of the skeletogenic gene regulatory network of sea urchins.

A central challenge of developmental and evolutionary biology is to understand the transformation of genetic information into morphology. Elucidating the connections between genes and anatomy will require model morphogenetic processes that are amenable to detailed analysis of cell/tissue behaviors and to systems-level approaches to gene regulation. The formation of the calcified endoskeleton of the sea urchin embryo is a valuable experimental system for developing such an integrated view of the genomic regulatory control of morphogenesis. A transcriptional gene regulatory network (GRN) that underlies the specification of skeletogenic cells (primary mesenchyme cells, or PMCs) has recently been elucidated. In this study, we carried out a genome-wide analysis of mRNAs encoded by effector genes in the network and uncovered transcriptional inputs into many of these genes. We used RNA-seq to identify >400 transcripts differentially expressed by PMCs during gastrulation, when these cells undergo a striking sequence of behaviors that drives skeletal morphogenesis. Our analysis expanded by almost an order of magnitude the number of known (and candidate) downstream effectors that directly mediate skeletal morphogenesis. We carried out genome-wide analysis of (1) functional targets of Ets1 and Alx1, two pivotal, early transcription factors in the PMC GRN, and (2) functional targets of MAPK signaling, a pathway that plays an essential role in PMC specification. These studies identified transcriptional inputs into >200 PMC effector genes. Our work establishes a framework for understanding the genomic regulatory control of a major morphogenetic process and has important implications for reconstructing the evolution of biomineralization in metazoans.

The genomic regulatory control of skeletal morphogenesis in the sea urchin.

A central challenge of developmental and evolutionary biology is to understand how anatomy is encoded in the genome. Elucidating the genetic mechanisms that control the development of specific anatomical features will require the analysis of model morphogenetic processes and an integration of biological information at genomic, cellular and tissue levels. The formation of the endoskeleton of the sea urchin embryo is a powerful experimental system for developing such an integrated view of the genomic regulatory control of morphogenesis. The dynamic cellular behaviors that underlie skeletogenesis are well understood and a complex transcriptional gene regulatory network (GRN) that underlies the specification of embryonic skeletogenic cells (primary mesenchyme cells, PMCs) has recently been elucidated. Here, we link the PMC specification GRN to genes that directly control skeletal morphogenesis. We identify new gene products that play a proximate role in skeletal morphogenesis and uncover transcriptional regulatory inputs into many of these genes. Our work extends the importance of the PMC GRN as a model developmental GRN and establishes a unique picture of the genomic regulatory control of a major morphogenetic process. Furthermore, because echinoderms exhibit diverse programs of skeletal development, the newly expanded sea urchin skeletogenic GRN will provide a foundation for comparative studies that explore the relationship between GRN evolution and morphological evolution.

The expression and distribution of Wnt and Wnt receptor mRNAs during early sea urchin development.

The protein beta-catenin plays a critically important role in establishing axial polarity during early animal development. In many organisms, beta-catenin is degraded preferentially on one side of the cleavage stage embryo. On the opposite side of the embryo, beta-catenin is stabilized and accumulates in the nucleus, where it functions in concert with members of the LEF/TCF family to activate the transcription of diverse target genes. Genes that are activated by beta-catenin play an essential role in the specification of endomesoderm and in the establishment of key signaling centers in the early embryo. In several organisms, the asymmetric distribution of maternal components of the canonical Wnt pathway has been shown to be responsible for the polarized stabilization of beta-catenin. In this study, we identified all Wnt and Wnt receptor mRNAs that are present in unfertilized sea urchin eggs and early embryos and analyzed their distributions along the primary (AV) axis. Our findings indicate that the asymmetric distribution of a maternal Wnt or Wnt receptor mRNA is unlikely to be a primary determinant of the polarized stabilization of beta-catenin along the AV axis. This contrasts sharply with findings in other organisms and points to remarkable evolutionary flexibility in the molecular mechanisms that underlie this otherwise very highly conserved patterning process.

Expansion of adult beta-cell mass in response to increased metabolic demand is dependent on HNF-4alpha.

The failure to expand functional pancreatic beta-cell mass in response to increased metabolic demand is a hallmark of type 2 diabetes. Lineage tracing studies indicate that replication of existing beta-cells is the principle mechanism for beta-cell expansion in adult mice. Here we demonstrate that the proliferative response of beta-cells is dependent on the orphan nuclear receptor hepatocyte nuclear factor-4alpha (HNF-4alpha), the gene that is mutated in Maturity-Onset Diabetes of the Young 1 (MODY1). Computational analysis of microarray expression profiles from isolated islets of mice lacking HNF-4alpha in pancreatic beta-cells reveals that HNF-4alpha regulates selected genes in the beta-cell, many of which are involved in proliferation. Using a physiological model of beta-cell expansion, we show that HNF-4alpha is required for beta-cell replication and the activation of the Ras/ERK signaling cascade in islets. This phenotype correlates with the down-regulation of suppression of tumorigenicity 5 (ST5) in HNF-4alpha mutants, which we identify as a novel regulator of ERK phosphorylation in beta-cells and a direct transcriptional target of HNF-4alpha in vivo. Together, these results indicate that HNF-4alpha is essential for the physiological expansion of adult beta-cell mass in response to increased metabolic demand.
