Metabolic pathway engineering to enhance aerobic degradation of chlorinated ethenes and to reduce their toxicity by cloning a novel glutathione S -transferase, an evolved toluene o -monooxygenase, and g -glutamylcyste...

MicroRNAs are a class of non-coding single-stranded RNA, 20-23 nucleotide in length, which can be involved in the regulation of gene expression. Through binding with 3'-untranslated regions (3'-UTR), microRNAs can cause degradation of target mRNAs or inhibition of translation, and thus regulating the expression of genes at the post-transcriptional level. In this study, we found that miR-486-5p ...

BACKGROUND MicroRNAs (miRNAs) are small non-coding RNAs involved in post-transcriptional gene regulation. miRNAs are taken in by intracellular exosomes, secreted into circulation, and taken up by other cells, where they regulate cellular functions. We hypothesized that muscle-enriched miRNAs existing in circulation mediate beneficial metabolic responses induced by exercise. To test this hypothe...

Background Kisspeptin is a potent stimulator of the hypothalamic- pituitary-gonadal axis and may play a critical role in modulating of stress-induced suppression of reproduction. The aim of the present study was to investigate the effect of glucocorticoid receptor antagonist (RU486) and stress on expression of Kiss-1 mRNA in arcuate nucleus (ARC) of rat hypothalamus.

BACKGROUND In this paper, paleoparasitological findings from rodent excrements obtained from Chehrabad Salt Mine archeological site located in northwest of Iran are demonstrated and discussed. METHODS Chehrabad Salt Mine archeological site located in northwest of Iran, dated to the Achaemenid (mid 1(st) mill. BCE) and to Sassanid (3(rd) cent. - 7(th) cent. CE) period, is a unique study area t...

Computed tomography studies and histological analyses were performed on the mummified remains found in Chehrābād salt mine northwestern Iran. The ancient mummies are dated to Achaemenid (550–330 BC) Sassanid (3rd–7th century AD) time period died mining incidents. aim of study was describe radiological findings several Iranian with special interest pathological postmortem changes. show multiple ...

The Brill–Hartle gravitational geon construct as a spherical shell of small amplitude, high frequency gravitational waves is reviewed and critically analyzed. The Regge–Wheeler formalism is used to represent gravitational wave perturbations of the spherical background as a superposition of tensor spherical harmonics and an attempt is made to build a non–singular solution to meet the requirement...
