AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Bile acids (BAs) are water-soluble end products from cholesterol metabolism and are essential for efficient absorption of dietary lipids. By using targeted somatic mutagenesis of the nuclear receptor liver receptor homolog 1 (LRH-1) in mouse hepatocytes, w ...
The intent of this thesis is to study the function of elastin in cerebral arteries, its contribution into the aging process and its implication into different cerebral diseases and in particular cerebral aneurysms. As of today, little is known on the genes ...
Earlier experimental work on decellularized arteries revealed the existence of significant residual stresses within the arterial wall, which are released upon chemical removal of vascular smooth muscle in normal arteries causing substantial radial expansio ...
Strengthening of dislocations by multiple obstacle types occurs in many engineering alloys. Theories have rationalized two different scaling laws for the total strength, tau(alpha)(t) = tau(alpha)(1) + tau(alpha)(2) with alpha = 1 or 2, where tau(1) and ta ...
Acting at postsynaptic alpha 1- and beta 1-receptors, norepinephrine (NE) exerts a complex action in rat hippocampus. It is currently believed that beta 1-receptor activation enhances excitability of recorded neurons, whereas alpha 1 activation suppresses ...
The radical C-glycosidation of (-)-(1S,4R,5R,6R)-6-endo-chloro-3-methylidene-5-exo-(phenylseleno)-7-oxa bicyclo[2.2.1]heptan-2-one ((-)-4) with 2,3,4,6-tetra-O-acetyl-alpha-D-mannopyranosyl bromide gave (+)-(1S,3R,4R,5R,6R)-6-endo-chloro-5-exo-(phenylselen ...
Adenosine promotes a concentration-dependent hydrolysis of 3H-glycogen newly synthesized from 3H-glucose by mouse cerebral cortical slices. The EC50 for this effect is 7 microM. Theophylline antagonizes the glycogenolysis induced by adenosine with an EC50 ...
Two related human alpha interferons with 83% homology in their primary sequences show a similar specific activity on nonhuman cells, but a striking difference on human cells, on which alpha-1 shows 1-5% of the specific molar activity displayed by alpha-2. ...
Seven different human interferon (IFN) alpha subtypes were compared with regard to competitive inhibition of specific high-affinity binding of 125I-labeled IFN alpha-2 to human and bovine cells. All IFNs tested (alpha-1, -2, -4, -5, -6, -7, -8) competed fo ...
