Delineation of loci governing an extra-earliness trait in lentil (Lens culinaris Medik.) using the QTL-Seq approach.

Developing early maturing lentil has the potential to minimize yield losses, mainly during terminal drought. Whole-genome resequencing (WGRS) based QTL-seq identified the loci governing earliness in lentil. The genetic analysis for maturity duration provided a good fit to 3:1 segregation (F), indicating earliness as a recessive trait.

Identification of quantitative trait loci (QTLs) regulating leaf SPAD value and trichome density in mungbean ( L.) using genotyping-by-sequencing (GBS) approach.

Quantitative trait loci (QTL) mapping is used for the precise localization of genomic regions regulating various traits in plants. Two major QTLs regulating Soil Plant Analysis Development (SPAD) value () and trichome density () in mungbean were identified using recombinant inbred line (RIL) populations (PMR-1×Pusa Baisakhi) on chromosome 7. Functional analysis of QTL region identified 35 candidate genes for SPAD value (16 No) and trichome (19 No) traits.

Genome-wide association studies for phenological and agronomic traits in mungbean ( L. Wilczek).

Mungbean ( L. Wilczek) is one of the important warm-season food legumes, contributing substantially to nutritional security and environmental sustainability. The genetic complexity of yield-associated agronomic traits in mungbean is not well understood.

Genetic Gain in Yield and Associated Changes in Agronomic Traits in Wheat Cultivars Developed Between 1900 and 2016 for Irrigated Ecosystems of Northwestern Plain Zone of India.

Knowledge about the yield gain over the years due to associated changes in the yield component traits is essential for a critical understanding of yield-limiting factors. To estimate genetic gain in grain yield (GY) and component agronomic traits of wheat varieties released between 1900 and 2016 for northwestern plain zone (NWPZ) of India and to identify agronomic and/or genetic basis of the realized gains, two sets of wheat varieties comprising mega varieties and two recently developed varieties were evaluated under timely sown, tilled, and early sown conservation agriculture (CA) conditions for four consecutive years under irrigated conditions. The average annual genetic gain in GY since 1,905 under timely sown irrigated conditions was found to be 0.

Evaluation of Endocrine Parameters as Predictor of Major Depressive Disorder.

Background: The diagnosis of the disease, major depressive disorder (MDD), entirely depends on the presence of some symptoms without any biochemical parameter to support it. Depletion of dopamine though is an established feature, is not the sole causative factor of MDD. Moreover, it has very little diagnostic value due to a short half-life.

Factors causing stress among students of a medical college in Kolkata, India.

Background: Medical students feel a significant amount of stress due to a variety of factors. Few studies have explored the relative size of these various stressors to identify which are most important. This study was undertaken to quantify the magnitude of various sources of stress among students of a medical college at Kolkata, West Bengal, and also to assess the reliability of Medical Students' Stressor Questionnaire (MSSQ-40) in this context.

Depression and type D personality among undergraduate medical students.

Context: Academic pressure, though established, is an unavoidable cause of depression in medical students. Role of Type D personality as determinant of depression is a new approach to the problem.

Aim: Determination of relationship between Type D personality and Depression among medical students.

The silent burden of anemia in school age children: a community based study in West Bengal.

Background: Under nutrition and anemia are common co-morbidities in school age children. Due to transition in dietary habits in developing countries, a paradoxical finding of coexistence of anemia and normal/over nutrition is also a cause of concern.

Objective: > T o assess the nutritional status and prevalence of anemia among school age children (6 - 16 years) residing in rural and urban areas of a district of West Bengal and also to find out the association between weight status, measured as Body Mass Index(BMI) and anemia.

A sociodemographic study of multidrug resistant tuberculosis cases from DOTS clinics of Kolkata.

This cross-sectional, observational study was undertaken to identify rifampicin and INH resistant mycobacteria in the sputum samples of category II treatment failure tuberculosis patients from three 'DOTS' clinics of Kolkata (Ward No 15, 33, 79 of Kolkata Municipal Corporation). Conventional method of culture in solid and liquid media followed by sensitivity testing to rifampicin and INH were done. Age, sex, economic status, nutrition, history of contact, living condition, etc, were taken into consideration.

Synthesis, biological evaluation of new oxazolidino-sulfonamides as potential antimicrobial agents.

A number of linezolid-like oxazolidino-sulfonamides (7a-y and 8a-b) were designed and synthesized with a view to develop antimicrobial agents with improved properties. Most of the synthesized compounds showed good to moderate activity against a panel of standard Gram-positive and Gram-negative bacteria and fungal strains. The compounds 7i and 7v exhibited significant activity, with a MIC value of 2.

Study of serum electrolytes in pregnancy induced hypertension.

Hypertension complicating pregnancy is an important cause of foetal and maternal mortality and morbidity. Serum sodium, potassium, calcium and magnesium were evaluated in cases with gestational hypertension and pre-eclampsia and compared with normotensive pregnant women of corresponding period of gestation. Taking urinary micro-albumin creatinine ratio as standard to predict pregnancy induced hypertension, the role of serum electrolytes to predict the same was studied.

Rapid identification of mycobacterium species with the aid of multiplex polymerase chain reaction (PCR) from clinical isolates.

Mycobacteria are aerobic, nonspore forming, non-motile,single-cell bacteria.Of more than 40 currently recognized species of mycobacteria, Mycobacterium tuberculosis, the causative agent of human TB is the commonest pathogen for pulmonary and extra pulmonary tuberculosis cases. The other members of the Mycobacterium tuberculosis complex (MTC) or the nontubercular mycobacterium (NTM) produces similar diseases which cannot be differentiated from tuberculosis by clinical symptoms and signs.

A hospital-based study to evaluate the incidence pattern of group A streptococcal throat infections from different age group patients.

Streptococcus pyogenes(group A) is a major pathogen capable of causing a wide range of diseases in different age group of people. In this study 100 patients were selected who presented with the complaint of sore throat. All the patients were divided in four age groups.

Multiplex PCR technique could be an alternative approach for early detection of leprosy among close contacts--a pilot study from India.

Background: Implementation of Multi drug Therapy (MDT) regimen has resulted in the decline of the total number of leprosy cases in the world. Though the prevalence rate has been declining, the incidence rate remains more or less constant and high in South East Asian countries particularly in India, Nepal, Bangladesh, Pakistan and Srilanka. Leprosy, particularly that of multibacillary type spreads silently before it is clinically detected.

Development and application of a new efficient and sensitive multiplex polymerase chain reaction (PCR) in diagnosis of leprosy.

India contributes about 80% of the global leprosy case load including case of fresh infection and reinfection. Due to lack of gold standard, diagnosis is done mainly based on routine clinical signs and symptoms, smear and histopathological evidences. There is a lot of lacunae in early confirmatory diagnosis in terms of sensitivity and specificity, especially in paucibacillary tuberculoid type.

Prevalence of hypothyroidism and importance of cholesterol estimation in patients suffering from major depressive disorder.

The coexistence of hypothroidism and depression is already reported and both of these conditions are known to share some common clinical symptoms. Serum cholesterol level is known to be altered in either condition considered separately. But, no report is obtained regarding serum cholesterol level when both the conditions coexist.

Role of oxidative stress and antioxidants in aetiopathogenesis and management of oral submucous fibrosis.

Lipid peroxidation product, malonaldehyde (MDA) and antioxidants were estimated in plasma and erythrocytes of 34 cases of oral submucous fibrosis (OSMF) of different grades with equal number of healthy controls to evaluate the association of reactive oxygen species (ROS) and OSMF. While plasma MDA was found to be significantly higher in patients (3.3±0.

Antifungal activity of amiodarone is mediated by disruption of calcium homeostasis.

The antiarrhythmic drug amiodarone was recently demonstrated to have novel broad range fungicidal activity. We provide evidence that amiodarone toxicity is mediated by disruption of Ca2+ homeostasis in Saccharomyces cerevisiae. In mutants lacking calcineurin and various Ca2+ transporters, including pumps (Pmr1 and Pmc1), channels (Cch1/Mid1 and Yvc1), and exchangers (Vcx1), amiodarone sensitivity correlates with cytoplasmic calcium overload.
