The present study was undertaken to investigate the toxic effects of higher doses (1,00,000 IU i.e. 2.5 mg/kg body weight (BW)) of vitamin D3, concomitantly with bacterial endotoxins (lipopolysaccharides: LPS) to study the immunomodulatory potential of vitamin D3 in IBL-80 broiler chicks. The chicks were divided into four groups [group I (NSS), group II (LPS), group III (Vit. D3 + NSS), and gro...

The extent to which vacuolar sugar transport activity affects molecular, cellular, and developmental processes in Arabidopsis (Arabidopsis thaliana) is unknown. Electrophysiological analysis revealed that overexpression of the tonoplast monosaccharide transporter TMT1 in a tmt1-2::tDNA mutant led to increased proton-coupled monosaccharide import into isolated mesophyll vacuoles in comparison wi...

The aim of this study was to evaluate the effects of the addition of antioxidants (vitamin E, β- mercaptoethanol and their combination) to semen extender.  Progressive motility, viability and pH of fresh ram semen were examined. Ejaculate samples were collected with artificial vagina from three Ghezel-Merinose rams (3 years old) during non- breeding reproduction season. Semen was diluted with a...

The Saccharomyces cerevisiae Tmt1 gene product is the yeast homologue of the Escherichia coli enzyme that catalyzes the methyl esterification of trans-aconitate, a thermodynamically favored isomer of cis-aconitate and an inhibitor of the citric acid cycle. It has been proposed that methylation may attenuate trans-aconitate inhibition of aconitase and other enzymes of the cycle. Although trans-a...

AIMS The purpose of this study is the comparison of the effect of vitamin B1 and fish oil with together on severity and duration of dysmenorrhea, and if it is effective, we can administrative both of them with less complication to compare with other chemical drugs which has many disadvantages. STUDY DESIGN High school of Urmia city, between March 2008 and June 2008. METHODOLOGY This study h...

lead belongs to the heavy metal group and is considered as an environmental contaminant. acute or chronic contact to lead can change the physiological function of human organs. one of the most important disorders following the lead exposure is neurotoxicity. lead neurotoxicity consists of the neurobehavioral disturbances like cognitive impairment. the aim of the current study is to evaluate the...

background: renal ischemia reperfusion injury may occur in a variety of clinical situations, following a transient drop in total or regional blood flow to the kidney. this study was performed to investigate the protective effects of different antioxidants such as vitamin c, vitamin e, hydrocortisone and combination of these agents against experimental renal ischemia-reperfusion injury. method:...

Sixty layers (50 weeks of age) each of native Desi, Fayoumi and commercial White Leghorn (Nick Chick) were kept in wire cages following completely randomized design for 8 weeks during summer season (June and July). The birds of each type were divided into two groups i.e. with and without supplementation of vitamin C with three replicates assigned to each layer group (10 birds in each replicate)...

BACKGROUND The risk of recurrent neural-tube defects is decreased in women who take folic acid or multivitamins containing such during the periconceptional period. The extent to which folic acid supplementation can reduce the first occurrence of defects is not known. METHODS We conducted a randomized, controlled trial of periconceptional multivitamin supplementation to test the efficacy of th...
