Presumptive role of Bhagottar Gutika in the management of Tamaka Shwasa (Bronchial Asthma): A Hypothetical Study

Bronchial asthma is one of the commonest repiratory disorders prevalent all over thr world. It is more common in industrialised countries and effects 5% of the population. It affects all age groups and mortality rate is increasing rapidly in past few years. The word asthma derived from a Greek word meaning ‘gasp for breath’. Since 20thcentuary it was seen as a unique illness characterized by ‘spasmodic afflictions of the bronchial tubes’. Its heterogenous pathophysiology shows transient increase in resistance of airways, reduction in forced expiratory capacities, Hyperinflation of lungs and increased load of breathing. In Ayurveda bronchial asthma shows resemblance with Tamaka Shwasa a type of Shwasaroga. Today asthma is introducing as a chronic inflammatory disease of airways and pathophysiology of this disease is unclarified yet. Inspite of unmatched growth and developments in contemporary world, there is still no such ideal drug which can control asthma and its complications completely. Hence to develop safer and more effective drug, a hypothetical study has been planned using a herbomineral formulation prepared in the form of Gutika i.e Bhagottar Gutika. The article reviews each ingredient of the formulation parallely with symptomology of asthma and also assesses the effects of this formulation in encountering basic pathology of the disease

Development and validation of a scale to measure faculty attitudes toward open educational resources

An ATOER scale (Attitudes Towards Open Educational Resources) was developed to identify positive and negative predispositions towards Open Educational Resources (OER) amongst teachers. Data was classified into three main constructs: awareness, sharing of resources, and adoption and use of OER. This instrument will help to understand psychological determinants of teachers that might influence adoption and use of OER. The content validity of the tool is explained in the presentation

Association of body mass index, hand grip strength and quality of life with response to anti-tubercular therapy in adult patients of pulmonary and extra-pulmonary tuberculosis

Background: Monitoring of anti-tubercular therapy (ATT) response necessary for successful completion of ATT regimen. Presently available monitoring tools are invasive and have limitations. This study undertaken to see whether non-invasive tools like body mass index (BMI), hand grip strength (HGS) and quality of life (QOL) can serve as a reliable tool for monitoring ATT response.Methods: The 50 patients of tuberculosis were monitored for BMI, HGS and QOL via WHOQOL-BREF questionnaire and analyzed at baseline, 2 months and 6 months of starting ATT.Results: BMI HGS increased significantly at 2 months and 6 months compared to baseline with ATT. Physical and social domain of WHOQOL-BREF increased at 2 and 6 months with ATT, other domains shown no significant changes.Conclusions: Monitoring of BMI, handgrip strength and QOL can be a cost-effective tool for monitoring ATT response, both in pulmonary and extra pulmonary tuberculosis

Residues of Pesticides and Herbicides in Soils from Agriculture Areas of Delhi Region, India

This paper presents the residue levels of organochlorine, organophosphate pesticides and herbicides in agricultural soils from Delhi region. Among OCPs, HCH, DDT endosulphan and dieldrin ranged between <0.01-104.14 ng g-1, <0.01-15.79 ng g-1, <0.01-7.57 ng g-1 and <0.01-2.38 ng g-1, respectively. The concentration of OPPs ranged from <0.01-20.95 ng g-1, ND-3.92 ng g-1, ND-31.73 ng g-1, ND-6.46 ng g-1 and ND-6.46 ng g-1 for phosphomidon, monocrotophos, chlorpyriphos, quinolphos and ethion, respectively. Pendimethalin (0.27 ng g-1) was the dominant herbicides followed by butachlor (0.19 ng g-1), and fluchloralin (0.05 ng g-1). Data showed the region was contaminated by technical DDT and technical HCH mixture. The study reveals that the level of some organochlorine pesticides in agricultural soils is a matter of concern for future food chain accumulation and human health so; regular investigation of pesticide residues is recommended on soil health and contamination levels. Keywords: pesticides, herbicides, agricultural soil, Delhi, Indi

Development of a scale to measure faculty attitude towards open educational resources

The study involves understanding why some teachers share educational resources and others do not. The paper describes the methodology for the development of an instrument to measure Attitude towards Open Educational Resources (ATOER) within the framework of research projects in the global south. It discusses various phases of development and validation of a scale which can measure faculty attitude towards Open Educational Resources (OER) and to present the findings through evidence of the impact of OER. The scale will help institutions to plan use of OER in teaching and learning by identifying positive and negative faculty attitudes

Distribution of polychlorinated biphenyls in agricultural soils from NCR, Delhi, India

ABSTRACT Twenty eight polychlorinated biphenyls (PCBs) congeners including twelve dioxin-lik

Pseudomonas aeruginosa Psl polysaccharide reduces neutrophil phagocytosis and the oxidative response by limiting complement-mediated opsonization: Psl and the innate immune response towards P. aeruginosa

Pseudomonas aeruginosa causes chronic lung infections in the airways of cystic fibrosis (CF) patients. Psl is an extracellular polysaccharide expressed by non-mucoid P. aeruginosa strains, which are believed to be initial colonizers. We hypothesized that Psl protects P. aeruginosa from host defences within the CF lung prior to their conversion to the mucoid phenotype. We discovered that serum opsonization significantly increased the production of reactive oxygen species (ROS) by neutrophils exposed to a psl-deficient mutant, compared with wild-type (WT) and Psl overexpressing strains (Psl++). Psl-deficient P. aeruginosa were internalized and killed by neutrophils and macrophages more efficiently than WT and Psl++ variants. Deposition of complement components C3, C5 and C7 was significantly higher on psl-deficient strains compared with WT and Psl++ bacteria. In an in vivo pulmonary competition assay, there was a 4.5-fold fitness advantage for WT over psl-deficient P. aeruginosa. Together, these data show that Psl inhibits efficient opsonization, resulting in reduced neutrophil ROS production, and decreased killing by phagocytes. This provides a survival advantage in vivo. Since phagocytes are critical in early recognition and control of infection, therapies aimed at Psl could improve the quality of life for patients colonized with P. aeruginosa

Role of Serine/Threonine Kinase 11 (STK11) or liver kinase B1 (LKB1) Gene in Peutz-Jeghers Syndrome

Peutz-Jeghers syndrome (PJS) is a well-described inherited syndrome, characterized by the development of gastrointestinal polyps and characteristic mucocutaneous freckling. PJS is an autosomal prevailing disease, due to genetic mutation on chromosome 19p, manifested by restricted mucocutaneous melanosis in association with gastrointestinal (GI) polyposis. The gene for PJS has recently been shown to be a serine/threonine kinase, known as LKB1 or STK11, which maps to chromosome subband 19p13.3. This gene has a putative coding region of 1302 bp, divided into nine exons, and acts as a tumor suppressor in the hamartomatous polyps of PJS patients and in the other neoplasms that develop in PJS patients. It is probable that these neoplasms develop from hamartomas, but it remains possible that the LKB1 or STK11 locus plays a role in a different genetic pathway of tumor growth in the cancers of PJS patients. This article focuses on the role of LKB1 or STK11 gene expression in PJS and related cancers

An overview of vaccine development for COVID-19

The COVID-19 pandemic continues to endanger world health and the economy. The causative SARS-CoV-2 coronavirus has a unique replication system. The end point of the COVID-19 pandemic is either herd immunity or widespread availability of an effective vaccine. Multiple candidate vaccines - peptide, virus-like particle, viral vectors (replicating and nonreplicating), nucleic acids (DNA or RNA), live attenuated virus, recombinant designed proteins and inactivated virus - are presently under various stages of expansion, and a small number of vaccine candidates have progressed into clinical phases. At the time of writing, three major pharmaceutical companies, namely Pfizer and Moderna, have their vaccines under mass production and administered to the public. This review aims to investigate the most critical vaccines developed for COVID-19 to date
