introduction: mental retardation, is one of the most common causes for referral to genetic counseling centers, and is one of the greatest challenges in health care services in the world. down syndrome is the most common chromosomal abnormalities in humans. methods: this study performed in medical genetic counseling center of welfare organization in south of iran with high consanguineous marriag...

Background: Salinity is a major environmental limiting factor, which affect agricultural production. The two Manilkara seedlings (M. roxburghiana and M. zapota) with high economic importance, could not adapt well to higher soil salinity and little is known about their proteomic mechanisms. Objectives: The mechanisms responsible ...

The transition from normal forage to a highly fermentable diet to achieve rapid weight gain in the cattle industry can induce ruminal acidosis. The molecular host mechanisms that occur in acidosis are largely unknown. Therefore, the histology and transcriptome profiling of rumen epithelium was investigated in normal and acidosis animals to understand the molecular mechanisms involved in the dis...

The electronic, and optical properties of rhombohedral Na0.5Bi0.5TiO3nanostructured thin film have been studied by the first–principle approach. Densityfunctional theory (DFT) has been employed to calculate the fundamental properties ofthe layers using full–potential linearized augmented plane–wave (FPLAPW) method. A2×2×1 supercell was constructed with two vacuum slabs o...

Objective(s): This study investigated the protective effect of tanshinone IIA sodium sulfonate (TSS) on ischemia-reperfusion (I/R) induced cardiac injury, and the underlying mechanism of action. Materials and Methods:Male Sprague-Dawley rats were subjected to a 30-min coronary arterial occlusion followed by 24 hours' reperfusion. Half an hour before the left coronary artery ligation, rats were ...
