In the present agricultural scenario, the major thrust is to increase crop productivity so as to ensure sustainability. In an earlier study, foliar application of thiourea (TU; a non physiological thiol based ROS scavenger) has been demonstrated to enhance the stress tolerance and yield of different crops under field condition. Towards this endeavor,(More)
Plant nutrition is one of the important areas for improving the yield and quality in crops as well as non-crop plants. Potassium is an essential plant nutrient and is required in abundance for their proper growth and development. Potassium deficiency directly affects the plant growth and hence crop yield and production. Recently, potassium-dependent(More)
Salt stress reveals differential antioxidant and energetics responses in glycophyte (Brassica juncea L.) and halophyte (Sesuvium portulacastrum L.) Salt stress, considered as one of the major environmental factors, decreases crop productivity worldwide and hence, investigations are being made to understand the cellular basis of salt tolerance in plants. In(More)
A case of a male patient with schizophrenic illness who developed neuroleptic malignant syndrome (NMS) following treatment with olanzapine is reported. Although typical neuroleptics are more frequently associated with NMS, atypical antipsychotics may also cause NMS. Case reports have been published concerning NMS and clozapine,(1) risperidone(2) and(More)
Pharmacogenetics of schizophrenia has not yet delivered anticipated clinical dividends. Clinical heterogeneity of schizophrenia contributes to the poor replication of the findings of pharmacogenetic association studies. Functionally important HTR3A gene single-nucleotide polymorphisms (SNPs) were reported to be associated with response to clozapine. The aim(More)
A novel antifungal chitosanase from Anabaena fertilissima, strain RPAN1, was characterized as a prelude to its use in biocontrol. The culture grown at 8:16 h L:D photoperiod showed highest chitosanase/antifungal activity under environmental and nutritional conditions of 43 μM of P level, pH 9.0 and temperature of 27°C. The transcriptional level of(More)
Plants being sessile in nature are often challenged to various abiotic stresses including temperature fluctuations, water supply, salinity, and nutrient availability. Exposure of plants to such environmental perturbations result in the formation of reactive oxygen species (ROS) in cells. To scavenge ROS, enzymatic and molecular antioxidants are produced at(More)
Arsenic (As) is a non-essential element, a groundwater pollutant, whose uptake by plants produces toxic effects. The use of As-contaminated groundwater for irrigation can affect the crop productivity. Realizing the importance of the Brassica juncea as a crop plant in terms of oil-yield, there is a need to unravel mechanistic details of response to As stress(More)
Marriage is a consensual and contractual relationship recognized by law. In India, there is a tremendous social and cultural pressure to marry. It is of paramount importance to discuss the relationship between marriage and mental illness in Indian scenario as marriage is perceived to be a panacea to mental illness by many. This review aims to explore(More)
