STUDENT FEEDBACK ON THE OBJECTIVE STRUCTURED COMPONENT OF THE PRACTICALEXAMINA TION IN PHARMACOLOGY

The study was planned to determine the attitude of undergraduate medical students towards the objective structured practical examination (OSPE) in pharmacology and to investigate any influence of sex, nationality and medium of instruction at school on these attitudes. The second year undergraduate medical students of the Manipal college of medical sciences, Pokhara, Nepal were asked to complete a questionnaire regarding the spotters and communication skills component of the practical examination. Students considered OSPE a good method of practical examination. The male students agreed more strongly that the spotters develops the ability to choose an appropriate drug while the female students were more in favour of OSPE over animal experimentation. The Sri Lankan students were less in favour of the introduction of stations testing skills as part of OSPE and also disagreed strongly with the point that communication skills should be conducted in a language other than English. Based on these observations, changes should be made in the teaching as well as evaluation methodologies to maximize learning.

Science Attitudes and Knowledge among Preclinical Medical Students in Pokhara, Nepal

Knowledge of science and the scientific method are important in learning about and using evidence-based medicine in practice. Courses in research methodology have been introduced for both medical students and practicing doctors. In Pokhara, the basic science subjects are taught in an integrated manner during the first four semesters of the undergraduate medical course. Studies on students’ attitudes towards and knowledge of science are lacking in medical colleges in Nepal. Hence the study was carried out to obtain information on students’ attitude towards and knowledge of science and scientific methodology among preclinical medical students and note the association, if any, of students’ attitudes and their demographic characteristics. The study was carried out in March 2005 among the students of the first four semesters at the Manipal College of Medical Sciences, Pokhara, Nepal using a questionnaire developed by Hren and coworkers. Two hundred and twenty students (overall response rate 73.3%) successfully completed the questionnaire. Seventy- five respondents were Nepalese, 115 were Indians, 27 were Sri Lankans and 3 belonged to other nationalities. The X±SD total attitude score was 147.4±10.8 (neutral score 135). The X±SD scores on the subscales, value of science to humanity, value of scientific methodology and value of science to medicine were 51.3±5.4, 39.6±3.7 and 58.5±5.9 (neutral scores were 36, 51 and 48 respectively). The knowledge score measured using a set of 8 multiple choice questions was 3.3±1.4. The attitude scores were lower and the knowledge score was comparable to that reported previously in a study in Croatia but higher than that reported from Southeast Europe

Impact of educational outreach visits by pharmacists on treatment of childhood diarrhoea-initial findings from Banke district, Nepal

Diarrhoea is one of the most common causes of mortality and morbidity in children in developing countries. Oral rehydration salts (ORS) and zinc are the primary tools used to fight diarrhoea in children. Educational outreach visits or academic detailing has been practiced over a period of time to improve prescribing behaviour in the developed countries. However, educational outreach programmes are very uncommon in Nepal. We conducted a pilot study to see the impact of educational outreach visits on the management of diarrhoea in children among 10 prescribers in the Banke district of Nepal. Initial findings suggest that there is a marked improvement on the prescribing of ORS and zinc by the prescribers after our intervention. Therefore it is planned to conduct the same study among a large number of prescribers in the Banke district of Nepal

Academic detailing as a possible source of drug information in the context of Nepal: a short review

The source of unbiased drug information is an integral part of evidence based practice. The status of evidence based practice in Nepal is very poor. One of the major factors associated with it, is the limited availability of new literature, and poor documentation and dissemination of the little available information. Academic detailing is an educational outreach program in which a trained health professional visits clinicians in their offices to provide evidence based information. So, there is a huge scope for academic detailing as a means to disseminate the available information in the context of Nepal. Research done worldwide has already shown improvement in the clinicians’ knowledge, their attitude and practice, improvement in their prescribing patterns and an increase in their adherence to clinical guidelines, following academic detailing. In Nepal, there are many topics which can be selected for academic detailing. Topics covering the information regarding newer drugs, diarrhoea treatment guidelines, the rational use of antimicrobials, the rationality of fixed dose combinations, nonsteroidal antinflammatory drugs (NSAIDs) and specialized devices for the administration of drugs, will be more relevant. Lack of local health statistics, lack of awareness about evidence based practice, challenges from pharmaceutical representatives and a lack of financing capability may be the major limitations for academic detailing in Nepal

Whole-Genome Sequence of Sungri/96 Vaccine Strain of Peste des Petits Ruminants Virus

We report the complete genome sequence of the Sungri/96 vaccine strain of peste des petits ruminants virus (PPRV). The whole-genome nucleotide sequence has 89 to 99% identity with the available PPRV genome sequences in the NCBI database. This study helps to understand the epidemiological and molecular characteristics of the Sungri/96 strain

Magnetic field dependence of critical current density in YBa<SUB>2</SUB>Cu<SUB>3</SUB>O<SUB>7</SUB>

We have measured the transport critical current densityJ cof sintered YBa2Cu3O7, in various applied fields up to 185 Oe at 77 K. We find a sharp decay ofJ cwith magnetic field. We show that this sharp decay is consistent with the low field hysteresis results of Groveret al. We argue that the observed field dependence is not caused by intragranular weak links

C. elegans MANF Homolog Is Necessary for the Protection of Dopaminergic Neurons and ER Unfolded Protein Response

Neurotrophic factors (NTFs) are important for the development, function, and survival of neurons in the mammalian system. Mesencephalic astrocyte-derived neurotrophic factor (MANF) and cerebral dopamine neurotrophic factor (CDNF) are two recently identified members of a novel family of NTFs in vertebrates that function to protect dopaminergic neurons. Although these genes are conserved across eukaryotes, their mechanism of neuroprotection is not fully understood. Sequence searches for MANF/CDNF homologs in invertebrates have identified a single ortholog that is most related to MANF. Here we report the in vivo characterization of the MANF gene, manf-1, in the nematode Caenorhabditis elegans. We found that manf-1 mutants have an accelerated, age-dependent decline in the survival of dopaminergic neurons. The animals also show increased endoplasmic reticulum (ER) stress, as revealed by reporter gene expression analysis of hsp-4, an ER chaperone BiP/GRP78 homolog, suggesting that a failure to regulate the ER unfolded protein response (ER-UPR) may be a contributing factor to dopaminergic neurodegeneration. Expression studies of manf-1 revealed that the gene is broadly expressed in a pattern that matches closely with hsp-4. Consistent with the requirements of manf-1 in the ER-UPR, we found that aggregates of α-Synuclein, a major constituent of Lewy bodies, were significantly increased in body wall muscles of manf-1 mutant animals. Overall, our work demonstrates the important role of manf-1 in dopaminergic neuronal survival and the maintenance of ER homeostasis in C. elegans

Comparative and temporal transcriptome analysis of peste des petits ruminants virus infected goat peripheral blood mononuclear cells

Peste des petits ruminanats virus (PPRV), a morbillivirus causes an acute, highly contagious disease – peste des petits ruminants (PPR), affecting goats and sheep. Sungri/96 vaccine strain is widely used for mass vaccination programs in India against PPR and is considered the most potent vaccine providing long-term immunity. However, occurrence of outbreaks due to emerging PPR viruses may be a challenge. In this study, the temporal dynamics of immune response in goat peripheral blood mononuclear cells (PBMCs) infected with Sungri/96 vaccine virus was investigated by transcriptome analysis. Infected goat PBMCs at 48 h and 120 h post infection revealed 2540 and 2000 differentially expressed genes (DEGs), respectively, on comparison with respective controls. Comparison of the infected samples revealed 1416 DEGs to be altered across time points. Functional analysis of DEGs reflected enrichment of TLR signaling pathways, innate immune response, inflammatory response, positive regulation of signal transduction and cytokine production. The upregulation of innate immune genes during early phase (between 2-5 days) viz. interferon regulatory factors (IRFs), tripartite motifs (TRIM) and several interferon stimulated genes (ISGs) in infected PBMCs and interactome analysis indicated induction of broad-spectrum anti-viral state. Several Transcription factors – IRF3, FOXO3 and SP1 that govern immune regulatory pathways were identified to co-regulate the DEGs. The results from this study, highlighted the involvement of both innate and adaptive immune systems with the enrichment of complement cascade observed at 120 h p.i., suggestive of a link between innate and adaptive immune response. Based on the transcriptome analysis and qRT-PCR validation, an in vitro mechanism for the induction of ISGs by IRFs in an interferon independent manner to trigger a robust immune response was predicted in PPRV infection

A review on development and application of plant-based bioflocculants and grafted bioflocculants

Flocculation is extensively employed for clarification through sedimentation. Application of eco-friendly plant-based bioflocculants in wastewater treatment has attracted significant attention lately with high removal capability in terms of solids, turbidity, color, and dye. However, moderate flocculating property and short shelf life restrict their development. To enhance the flocculating ability, natural polysaccharides derived from plants are chemically modified by inclusion of synthetic, nonbiodegradable monomers (e.g., acrylamide) onto their backbone to produce grafted bioflocculants. This review is aimed to provide an overview of the development and flocculating efficiencies of plant-based bioflocculants and grafted bioflocculants for the first time. Furthermore, the processing methods, flocculation mechanism, and the current challenges are discussed. All the reported studies about plant-derived bioflocculants are conducted under lab-scale conditions in wastewater treatment. Hence, the possibility to apply natural bioflocculants in food and beverage, mineral, paper and pulp, and oleo-chemical and biodiesel industries is discussed and evaluated

Modulation of Host miRNAs Transcriptome in Lung and Spleen of Peste des Petits Ruminants Virus Infected Sheep and Goats

Peste des petits ruminants (PPR) is one of the highly contagious viral disease, characterized by fever, sore mouth, conjunctivitis, gastroenteritis, and pneumonia, primarily affecting sheep and goats. Reports suggested variable host response in goats and sheep and this host response vis-a-vis the expression of microRNAs (miRNAs) has not been investigated. Here, miRNAs were sequenced and proteomics data were generated to identify the role of differentially expressed miRNA (DEmiRNA) in PPR virus (PPRV) infected lung and spleen tissues of sheep and goats. In lungs, 67 and 37 DEmiRNAs have been identified in goats and sheep, respectively. Similarly, in spleen, 50 and 56 DEmiRNAs were identified in goats and sheep, respectively. A total of 20 and 11 miRNAs were found to be common differentially expressed in both the species in PPRV infected spleen and lung, respectively. Six DEmiRNAs—miR-21-3p, miR-1246, miR-27a-5p, miR-760-3p, miR-320a, and miR-363 were selected based on their role in viral infections, apoptosis, and fold change. The target prediction analysis of these six selected DEmiRNAs from the proteome data generated, revealed involvement of more number of genes in lung and spleen of goats than in sheep. On gene ontology analysis of host target genes these DEmiRNAs were found to regulate several immune response signaling pathways. It was observed that the pathways viz. T cell receptor signaling, Rap1 signaling, Toll-like receptor signaling, and B cell receptor signaling governed by DEmiRNAs were more perturbed in goats than in sheep. The data suggests that PPRV-induced miR-21-3p, miR-320a, and miR-363 might act cooperatively to enhance viral pathogenesis in the lung and spleen of sheep by downregulating several immune response genes. The study gives an important insight into the molecular pathogenesis of PPR by identifying that the PPRV—Izatnagar/94 isolate elicits a strong host response in goats than in sheep
