Depression, Anxiety and Stress Reduction in Medical Education: Humor as an Intervention

Background: In recent years there has been a growing appreciation of the issues of quality of life and stresses involved in medical training as this may affect their learning and academic performance. Objective of the study was to explore the effectiveness of humor when used as intervention in large group teaching over negative emotions amongst students. Method: The present Interventional, Randomized control trial study was carried out on medical students of 4th Semester of RMCH, Bareilly, which has total 90 students. Using simple random sampling lottery method the whole class was divided in two groups-A and B consisting of 45 students each. Group A as control group and Group B experimental group. In first and last lecture of both groups Dass-21 was used as measuring scale, for depression, anxiety and stress and results were compared to see the effect of humor on these three negative emotions. Result: Comparison of Severe and Extremely severe Stress: In Group A 40.54% in class -1 increased to 47.54% in class- 4, while in group B initial 13.15 % was reduced to 0 % (highly significant). Anxiety: In group A, after Class 1 -57.45% increased to 61.11% after class 4, while in group B, after class 1- 23.68% reduced to 2.27% only (highly significant). Depression: In group A, after Class 1 - 40.53% & 41.66 % after class 4 (not significant), while in group B, after class 1- 18.41% reduced to 0% (highly significant). Conclusion: In present study humor was found to be very effective intervention in relieving students on their negative emotions of depression, anxiety and stress to a larger extent. Further research would justify the use of humor as an effective teaching aid in medical education

Role of root exudates in plant-microbe interactions

The interactions in the rhizosphere are leading to a highly structured microbial community which, to a great deal, is influenced by the root exudates of plant origin. In this review, we have included the different types of interaction with special regard to the root exudates’ function in such positive or negative interactions beween plants and both bacterial and fungal partners of the plant in the rhizosphere, including mycorrhiza, nitrogen-fixing symbionts, plant growth promoting rhizobacteria endophytes and biological control organisms as well as allelopathy, antimicrobial effects and effects on nematodes. The differences in root exudates induced by microbial associations, role of quorum sensing in structuring communitites and effect on biogeochemical cycles are reviewed. The focus is put on agricultural systems and implications for ecosystems on arable land are drawn

Wheat x Azotobacter x VA Mycorrhiza interactions towards plant nutrition and growth – a review

Nitrogen-fixing and phosphate-mobilizing bateria, as well as mycorrhizal fungi, can influence plant nutrition beneficially and thus be used as biofertilizers in agriculture. This paper briefly reviews the role of wheat genotypes in the interaction of wheat with soil microorganisms like phosphate solubilizing and nitrogen fixing bacteria, specifically Azotobacter sp., and with mycorrhizal fungi for the development of sustainable wheat crop production. The role of rhizosphere microorganisms and the mechanisms, factors affecting response of bioinoculants and the possibilities of breeding wheat genotypes responsive to these bioinoculants for sustainable wheat production in semi-arid tropics are discussed.

The Global Ant Biodiversity Informatics (GABI) database: synthesizing data on the geographic distribution of ant species (Hymenoptera: Formicidae)

The global distribution patterns of most vertebrate groups and several plant groups have been described and analyzed over the past few years, a development facilitated by the compilation of important databases. Similar efforts are needed for large insect groups that constitute he majority of global biodiversity. As a result of this lack of information, invertebrate taxa are often left out of both large-scale analyses of biodiversity patterns and large-scale efforts in conservation planning and prioritization. Here, we introduce the first comprehensive global database of ant species distributions, the Global Ant Biodiversity Informatics (GABI) database, based on the compilation of 1.72 million records extracted from over 8811 publications and 25 existing databases. We first present the main goals of the database, the methodology used to build the database, is well as its limitations and challenges. Then, we discuss how different fields of ant biology may benefit from utilizing this tool. Finally, we emphasize the importance of future participation of myrmecologists to improve the database and use it to identify and fill holes in our knowledge of ant biodiversity.published_or_final_versio

Beginning of the End of Cost Competitiveness in CEE Countries - Analysis of Dependence between Labor Costs and Internationalization of the Region

In order to exemplify the above econometric model I carried out empirical analysis of the companies listed on the Warsaw Stock Exchange, identifying the companies for which efficiency-seeking is the main internationalization motive. The analysis of internationalization of 26 companies during the years 1990-2010 clearly shows that a significant part of investments is located outside the territory of Poland, in the countries with lower labor costs. This fact confirms that CEE countries will gradually become less and less attractive in terms of costs not only for MNEs from developed countries but also for the companies originating from transition economies.Głównym celem artykułu jest weryfikacja, czy niski poziom kosztów pracy w Europie Środkowej i Wschodniej będący do tej pory jednym z czynników wpływających na konkurencyjność tego regionu pozostanie nim w dłuższej perspektywie czasowej. W pracy na podstawie próby wszystkich państw UE zbadano zależność pomiędzy poziomem internacjonalizacji (stan odpływu BIZ per capita) a kosztami pracy w sektorze przedsiębiorstw i GNP per capita. Analiza regresji potwierdziła istnienie zależności pomiędzy wyżej wymienionymi czynnikami. Oznacza to, że stopniowy wzrost kosztów pracy w państwach Europy Środkowej i Wschodniej prowadził będzie do stopniowego odpływu BIZ z tego regionu do państw bardziej konkurencyjnych kosztowo. W celu egzemplifikacji powyższych zależności w pracy dodatkowo przedstawiono analizę inwestycji zagranicznych polskich spółek notowanych na GPW, z których to 26 dokonało inwwestycji zagranicznych o wyraźnych motywach związanych z obniżeniem kosztów produkcji. Fakt ten potwierdza powolny spadek konkurencyjności kosztowej polskiej gospodarki, tym samym zmusza do poszukiwania nowych rozwiązań instytucjonalnych mogących utrzymać konkurencyjność polskiej gospodarki w długim okresie

Generalized seizures during cataract surgery following peribulbar block: A case report

Local anesthesia techniques are commonly used to perform the cataract surgery. Among these techniques, peribulbar anesthesia(PBA), when compared to retrobulbar anesthesia, is more effective and safe. However, PBA is not without risk. Complications mayarise which if not recognized early and resuscitated, can be fatal. A 70-year-old Indian female was admitted for cataract extractionand lens implant in her left eye. Lignocaine sensitivity was done and showed no abnormal reaction. She developed generalized tonicclonicconvulsions following peribulbar block. This case report attempts to highlight the need for a trained personnel, compliancewith safety standards in anesthesia, awareness, and early recognition of the possible complications and their management

Identification of a 200-kD, brefeldin-sensitive protein on Golgi membranes

A mAb AD7, raised against canine liver Golgi membranes, recognizes a novel, 200-kD protein (p200) which is found in a wide variety of cultured cell lines. Immunofluorescence staining of cultured cells with the AD7 antibody produced intense staining of p200 in the juxtanuclear Golgi complex and more diffuse staining of p200 in the cytoplasm. The p200 protein in the Golgi complex was colocalized with other Golgi proteins, including mannosidase II and beta-COP, a coatomer protein. Localization of p200 by immunoperoxidase staining at the electron microscopic level revealed concentrations of p200 at the dilated rims of Golgi cisternae. Biochemical studies showed that p200 is a peripheral membrane protein which partitions to the aqueous phase of Triton X-114 solutions and is phosphorylated. The p200 protein is located on the cytoplasmic face of membranes, since it was accessible to trypsin digestion in microsomal preparations. and is recovered in approximately equal amounts in membrane pellets and in the cytosol of homogenized cells. Immunofluorescence staining of normal rat kidney cells exposed to the toxin brefeldin A (BFA), showed that there was very rapid redistribution of p200, which was dissociated from Golgi membranes in the presence of this drug. The effect of BFA was reversible, since upon removal of the toxin, AD7 rapidly reassociated with the Golgi complex. In the BFA-resistant cell line PtK1, BFA failed to cause redistribution of p200 from Golgi membranes. Taken together, these results indicate that the p200 Golgi membrane-associated protein has many properties in common with the coatomer protein, beta-COP

COVID-19 presenting as stroke

© 2020 Elsevier Inc. Objective: Acute stroke remains a medical emergency even during the COVID-19 pandemic. Most patients with COVID-19 infection present with constitutional and respiratory symptoms; while others present with atypical gastrointestinal, cardiovascular, or neurological manifestations. Here we present a series of four patients with COVID-19 that presented with acute stroke. Methods: We searched the hospital databases for patients that presented with acute stroke and concomitant features of suspected COVID-19 infection. All patients who had radiographic evidence of stroke and PCR-confirmed COVID-19 infection were included in the study. Patients admitted to the hospital with PCR- confirmed COVID-19 disease whose hospital course was complicated with acute stroke while inpatient were excluded from the study. Retrospective patient data were obtained from electronic medical records. Informed consent was obtained. Results: We identified four patients who presented with radiographic confirmation of acute stroke and PCR-confirmed SARS-CoV-2 infection. We elucidate the clinical characteristics, imaging findings, and the clinical course. Conclusions: Timely assessment and hyperacute treatment is the key to minimize mortality and morbidity of patients with acute stroke. Stroke teams should be wary of the fact that COVID-19 patients can present with cerebrovascular accidents and should dawn appropriate personal protective equipment in every suspected patient. Further studies are urgently needed to improve current understandings of neurological pathology in the setting of COVID-19 infection
