Reports of L-Norvaline Toxicity in Humans May Be Greatly Overstated

AdipoRon may be benefit for atherosclerosis prevention

Atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. Adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. Disturbed adiponectin actions through its receptor, (AdipoR1 and AdipoR2) may be involved in atheros...

Crystal structure of the tripeptide N-(benzyl­oxycarbon­yl)glycylglycyl-l-norvaline

The title tripeptide, C17H23N3O6, contains a nonproteinogenic C-terminal amino acid residue, norvaline, which is an isomer of the amino acid valine. Norvaline, unlike valine, has an unbranched side chain. The mol-ecule has a Gly-Gly segment which adopts an extended conformation. The norvaline residue also adopts an extended backbone conformation while its side chain has a g (+) t conformation. ...

The Commutant of L(h) in Its Ultrapower May or May Not Be Trivial

Kirchberg asked in 2004 whether the commutant of L(H) in its (norm) ultrapower is trivial. Assuming the Continnuum Hypothesis, we prove that the answer depends on the choice of the ultrafilter. Let H be a separable infinite dimensional complex Hilbert space, fixed throughout. The purpose of this paper is to prove that, assuming the Continnuum Hypothesis, the commutant of L(H) (the algebra of bo...

Reports of the length dependence of fatigue are greatly exaggerated.

Relative force depression associated with muscle fatigue is reported to be greater when assessed at short vs. long muscle lengths. This appears to be due to a rightward shift in the force-length relationship. This rightward shift may be caused by stretch of in-series structures, making sarcomere lengths shorter at any given muscle length. Submaximal force-length relationships (twitch, double pu...

Common Methods Bias: Reports of Its Death are Greatly Exaggerated
