BACKGROUND The great clinical potential of myocardial β-AR imaging has been shown by recent studies evaluating the β-AR-specific, non-selective agent [(11)C]-CGP12177 in the setting of idiopathic-dilated cardiomyopathy, and myocardial infarction. However, the short half-life of (11)C hampers the potential of [(11)C]-CGP12177 for routine clinical use. AMI9 is an analog of the β-adrenoceptor liga...
In circumstances such as in vitro fertilization (IVF) or in patients with luteal phase defect, one needs to ensure the establishment of pregnancy as soon as possible. At the same time, a question arises: How can a physician make sure that the β-hCG is of an endogenous source and not the residue of the prescribed drugs (hCG)? In this article we have studied the elimination time of 1M inject...
Our objective was to perform a genome-wide association study for content in bovine milk of α(S1)-casein (α(S1)-CN), α(S2)-casein (α(S2)-CN), β-casein (β-CN), κ-casein (κ-CN), α-lactalbumin (α-LA), β-lactoglobulin (β-LG), casein index, protein percentage, and protein yield using a 50K single nucleotide polymorphism (SNP) chip. In total, 1,713 Dutch Holstein-Friesian cows were genotyped for 50,22...
واکنش بیجینلی اولین بار در سال 1893 توسط پیترو بیجینلی انجام شد. این واکنش، یک واکنش چند جزئی ساده و مفید برای سنتز دی هیدرو پیریمیدینون ها با استفاده از αو β- کتو استرها، آلدهید ها و اوره یا تیو اوره در حضور اسید های لوئیس یا اسید های معدنی است. دی هیدرو پیریمیدینون ها در سالهای اخیر، به دلیل خواص دارویی و درمانی زیاد از جمله خواص ضدویروسی، ضد باکتریایی، کاهش دهنده فشار خون و ضد توموری توجها...

As β-glucosidases represent the major bottleneck for industrial degradation of plant biomass, great efforts are being devoted to discover both novel and robust versions these enzymes, as well develop efficient inexpensive ways produce them. In this work, raw glycerol from chemical production biodiesel was tested carbon source fungus Talaromyces amestolkiae with aim producing enzyme β-glucosidas...
BACKGROUND To test for cross-sectional (at age 11) and longitudinal associations between objectively measured free-living physical activity (PA) and academic attainment in adolescents.Method Data from 4755 participants (45% male) with valid measurement of PA (total volume and intensity) by accelerometry at age 11 from the Avon Longitudinal Study of Parents and Children (ALSPAC) was examined. Da...
A major pathological hallmark of Alzheimer's disease is accumulation of amyloid-β in senile plaques in the brain. Evidence is accumulating that decreased clearance of amyloid-β from the brain may lead to these elevated amyloid-β levels. One of the clearance pathways of amyloid-β is transport across the blood-brain barrier via efflux transporters. P-glycoprotein, an efflux pump highly expressed ...
