TORC1 mediated regulation of mitochondrial integrity and calcium ion homeostasis by Wat1/mLst8 in S. pombe.

The mTOR complexes play a fundamental role in mitochondrial biogenesis and cellular homeostasis. Wat1, an ortholog of mammalian Lst8 is an important component of TOR complex and is essential for the regulation of downstream signaling. Earlier we reported the role of Wat1 in oxidative stress response.

Spatio-temporal variation of fluoride in groundwater and agricultural soil and crops of Unnao district, UP: Monitoring and assessment.

Fluoride (F) contamination in groundwater of Unnao district, Uttar Pradesh was reported for the first time in 1994, however comprehensive monitoring of F in different environmental matrices remains to be undertaken. The presented study reports spatio-temporal monitoring of F content in groundwater, crops and soil from F affected district Unnao, in pre-monsoon (PRM), monsoon (MO) and post-monsoon (PMO), to establish F groundwater-soil-plant continuum. More than 80% of groundwater samples were contaminated with F> 1.

Elevated advanced glycation end products are associated with subfoveal ellipsoid zone disruption in diabetic macular edema.

Purpose: Advanced glycation end products (AGEs), due to increased production and a slow turnover rate, serve as mediators of "metabolic memory" even after the resolution of hyperglycemia. A prospective study was undertaken to evaluate the association of AGEs with subfoveal ellipsoid zone (EZ) disruption in diabetic macular edema (DME).

Methods: A tertiary-care-center-based cross-sectional study included 40 consecutive cases with DME and 20 healthy controls in the age group of 40-65 years.

Resource recovery through bioremediation of wastewaters and waste carbon by microalgae: a circular bioeconomy approach.

Microalgal biomass-based biofuels are a promising alternative to fossil fuels. Microalgal biofuels' major obstacles are the water and carbon sources for their cultivation and biomass harvest from the liquid medium. To date, an economically viable process is not available for algal based biofuels.

Thermostable cellulases: Current status and perspectives.

It is envisaged that the utilization of lignocellulosic biomass for ethanol production for transport sector, would make cellulases the most demanded industrial enzyme. The greatest potential of cellulolytic enzymes lies in ethanol production from biomass by enzymatic hydrolysis of cellulose but low thermostability and low titer of cellulase production resulting into high cost of the enzyme which is the major set-back. A number of research groups are working on cellulase to improve its thermostability so as to be able to perform hydrolysis at elevated temperatures which would eventually increase the efficiency of cellulose hydrolysis.

Preparation and optimization of a dry powder for inhalation of second-line anti-tuberculosis drugs.

A spray drying process was standardized to prepare an inhalable powder comprising d-cycloserine and ethionamide, two "second line" drugs employed for treating multi-drug resistant (MDR) tuberculosis (TB). The aim of the process development effort was to maximize product yield. Contour plots were generated using a small central composite design (CCD) with face centered (α = 1) to maximize the process yield as the response criterion.

Synthesis and in vitro studies of PLGA-DTX nanoconjugate as potential drug delivery vehicle for oral cancer.

Advances in nanotechnology have led to the design of multifunctional nanoparticles capable of cellular imaging, targeted drug delivery, and diagnostics for early cancer detection. We synthesized poly(lactic--glycolic acid) nanoparticles encapsulating a model radiosensitizing drug docetaxel accomplishing localized in situ delivery of the sensitizer to the tumor site. The synthesized nanoparticles have been characterized for their physicochemical properties.

Isolation and characterization of a novel Gram-negative bacterium Chromobacterium alkanivorans sp. nov., strain IITR-71T degrading halogenated alkanes.

The taxonomic position of a Gram-stain negative, non-violaceinpigmented bacterium isolated from an insecticide-contaminated site was characterized by a polyphasic approach. The bacterium was able to grow on three different halogenated compounds namely 1-hlorobutane, 1-hloropropane and 1,2-ichloroethane. As a critical step in the degradation of these haloalkanes, stoichiometric amounts of dechlorination were estimated.

Airborne foliar transfer of PM bound heavy metals in Cassia siamea: A less common route of heavy metal accumulation.

In order to investigate possible foliar transfer of toxic heavy metals, concentrations of Cd, Pb, and Fe were measured in samples of: Cassia siamea leaves (a common tree) Cassia siamea foliar dust, nearby road dust, and soil (Cassia siamea tree roots) at six different sites in/around the Bilaspur industrial area and a control site on the university campus. Bilaspur is located in a subtropical central Indian region. The enrichment factor (EF) values of Pb and Cd, when derived using the crustal and measured soil Fe data as reference, indicated significant anthropogenic contributions to Pb and Cd regional pollution.

Plasma Fibrinogen Is a Natural Deterrent to Amyloid Beta-Induced Platelet Activation.

Alzheimer's disease (AD) is a devastating neurodegenerative disorder, characterized by extensive loss of neurons, and deposition of amyloid beta (Aβ) in the form of extracellular plaques. Aβ is considered to have critical role in synaptic loss and neuronal death underlying cognitive decline. Platelets contribute to 95% of circulating amyloid-precursor protein that releases Aβ into circulation.

Taxonomic description and genome sequence of Rheinheimera mesophila sp. nov., isolated from an industrial waste site.

Protein-ligand interaction studies of retinol-binding protein 3 with herbal molecules using AutoDock for the management of Eales' disease.

Eales' disease is an idiopathic retinal vasculitis of the eye. The disease is predominantly characterized by recurrent vitreous hemorrhage. Interphotoreceptor retinol-binding protein 3 plays a significant role in the etiopathogenesis of this condition.

Evaluating risks of acquired clinical vulnerability among subjects exposed to E-waste.

Acquired clinical vulnerability (ACV) results from insults that produce consequential pathophysiological changes and predispose exposed subjects to future disease. ACV comprises a complex biological process that is manifested by exposure to toxicants, generally over the course of many years, and results from subtle changes that occur at the cellular and molecular level. A large proportion of the world's population has already been, or will be, exposed to toxicants emanating from E-waste during the course of their lives.

Nitratireductor lucknowense sp. nov., a novel bacterium isolated from a pesticide contaminated soil.

A straw-yellow pigmented bacterium, strain IITR-21(T) was isolated from a pesticide contaminated site and characterized by using a polyphasic taxonomic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genus Nitratireductor. Phylogenetic analysis of the 16S rRNA gene sequence showed that the strain IITR-21(T) belongs to the genus Nitratireductor and was moderately related to Nitratireductor indicus C115(T) (97.

Blood lead levels in children of Lucknow, India.

After implementing measures to control lead pollution in many countries, blood lead levels (BLLs) in children have been declined. The phase-out of leaded petrol began in Lucknow, the capital of most populated state, Uttar Pradesh in India on April 1, 2000. We evaluated the mean BLL and associated risk factors for lead exposure in Lucknow children (3-12 years) after petrol lead phase-out activity.

Placental lead-induced oxidative stress and preterm delivery.

It has been reported that impaired oxidant/antioxidant status is involved in a variety of pregnancy complications. To elucidate the possible free radical mediated mechanism of preterm delivery due to lead exposure by determining the placental lead level and oxidant/antioxidant status in women with the preterm and full-term deliveries. Twenty-nine women with preterm deliveries (gestational age 28-37 weeks) and 31 women with full-term deliveries (gestational age >37 weeks) attending a local hospital of Lucknow, India were recruited.
