Reactive oxygen species (ROS) are implicated as agents of cellular damage in pulmonary oxygen toxicity. Glutathione (GSH) and GSH-dependent antioxidant enzymes protect against damage by ROS, and recycling of glutathione disulfide (GSSG) to GSH by glutathione reductase (GR) is essential for the optimum functioning of this system. Exposure to hyperoxia inhibits lung development in newborn animals...

drought stress is one of the important problems in arid and semi_arid regions. drought stress take place in plants when available water is lesser than evapotranspiration. in order to evaluate the effect of drought stress on morphological traits and yield of three medicinal plants an experiment was carried out during the 2010 year in research greenhouse of faculity of agriculture, ferdowsi unive...

Introduction: The fate of xenobiotics that is present, increasing day by day. The increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. Methods: The present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by Panax ginse...

We have screened a panel of tetracycline (tc)-like compounds for their potential use with tc-repressor (tetR) based gene switches. The interaction between tc and tetR appears quite specific, as only tc itself and its close homologues anhydro-tc and doxycycline strongly inhibited DNA binding. However, a single tc-like compound, GR33076X, increased DNA binding of the tetR-VP16 fusion protein, bot...

The aim of this study was to determine the in vitro inhibitory effects some metal ions (silver ion (Ag+), cadmium (Cd2+), cobalt (Co2+), copper (Cu2+), nickel (Ni2+), lead (Pb2+) and zinc (Zn2+)) on glutathione reductase (GR) enzyme activities that purified from gill, kidney liver tissues Capoeta umbla. For purpose, C. umbla freshwater fish using ammonium sulfate precipitation affinity column c...

SETTING An urban slum in Kamrangirchar, Bangladesh. OBJECTIVES Among children aged 6-59 months seeking medical care from the two Médecins Sans Frontières-supported primary health centres, to determine 1) the prevalence of severe acute malnutrition (SAM) and severe chronic malnutrition (SCM), and 2) the extent of overlap between SAM and SCM. DESIGN In a retrospective record review, data were...

Abstract This study focuses on the microstructure characteristics and mechanical properties of unreinforced reinforced ceramic materials titanium diboride (TiB 2 ) graphite (Gr). Aluminium hybrid metal matrix nanocomposites with varying weight percentage nano TiB (0-12.5 wt. %) Gr (4wt via electromagnetic stir casting process to produce samples. Identification phases analysis are performed thro...
