Cypermethrin is reported to affect astrocytes in rat brain; however, its mechanism of action is obscure. Here, we observed an increase in apoptosis in the cortical astrocytes upon treatment of rats with cypermethrin. We then characterized the mechanism governing the apoptosis. Because the epidermal growth factor receptor (EGFR) signaling regulates the(More)
A rapid and economical method for the simultaneous determination of 20 amino acids in complex biological and food matrices (hair, urine and soybean seed samples) has been developed using ultrasound assisted dispersive liquid-liquid micro extraction (UA-DLLME). The method involves simultaneous derivatization and extraction followed by gas chromatography-mass(More)
Inadequate maternal intake of omega-3-fatty acids (omega3 FAs) causes adverse neurodevelopmental outcome in the progeny; however, their molecular mechanism of action is obscure. Since omega3 FAs are known to inhibit neuronal apoptosis during neuro-degeneration, we investigated their possible contribution in regulating neuronal apoptosis during brain(More)
Anthropogenic activities associated with industrialization, agriculture and urbanization have led to the deterioration in water quality due to various contaminants. To assess the status of urban drinking water quality, samples were collected from the piped supplies as well as groundwater sources from different localities of residential, commercial and(More)
The increasing use of nanotechnology in our daily life can have many unintended effects and pose adverse impact on human health, environment and ecosystems. Wider application of engineered nanoparticles, especially TiO2 nanoparticles (TiO2 NP) necessitates the understanding of toxicity and mechanism of action. Metabolomics provides a unique opportunity to(More)
We have evaluated the effect of an integrated (nano-bio) technique involving the use of stabilized Pd/Fe(0) bimetallic nanoparticles (CMC-Pd/nFe(0)) and a Sphingomonas sp. strain NM05, on the degradation of γ-HCH in soil. Factors affecting degradation such as pH, incubation temperature and γ-HCH initial concentration were also studied. The results revealed(More)
Metabolomics technology has enabled an important method for the identification and quality control of Traditional Chinese Medical materials. In this study, we isolated metabolites from cultivated Dendrobium officinale and Dendrobium huoshanense stems of different growth years in the methanol/water phase and identified them using gas chromatography coupled(More)
Proteasome inhibitors have potential for the treatment of cervical cancer. We describe the synthesis and biological characterization of a new series of 1,3-diphenylpropen-1-one (chalcone) based derivatives lacking the boronic acid moieties of the previously reported chalcone-based proteasome inhibitor 3,5-bis(4-boronic acid(More)
Because of minimal data available on folate analysis in dried matrix spots (DMSs), we combined the advantages of stable isotope dilution assays followed by LC-MS/MS analysis with DMS sampling to develop a reliable method for the quantitation of plasma 5-methyltetrahydrofolic acid in dried blood spots (DBSs) and dried plasma spots (DPSs) as well as for the(More)
The present article reports first time the use of solid-phase microextraction (SPME) and dispersive liquid-liquid microextraction (DLLME) to extract pregabalin (PRG) from urine and pharmaceutical formulations followed by GC-MS analysis after ethyl chloroformate (ECF) derivatization. PRG is an antiepileptic and analgesic drug, which is a structural analogue(More)
