In the literature, a deficiency of magnesium or vitamin B1 in alcoholics is considered of etiologic importance in the development of delirium tremens or alcoholic encephalopathy (AE). As AE are comprised mnestic disorders, so severe as to lead to social invalidation, Korsakoff syndrome and dementia. Upon admission, the plasma concentrations of magnesium and vitamin B1 were determined in cases w...

We report far-infrared Herschel observations obtained between 70 μm and 500 μm of two star-forming dusty condensations, [HKM99] B1-bS and [HKM99] B1-bN, in the B1 region of the Perseus star-forming cloud. In the western part of the Perseus cloud, B1-bS is the only source detected in all six PACS and SPIRE photometric bands, but it is not visible in the Spitzer map at 24 μm. B1-bN is clearly det...

The present study was performed to: (a) evaluate the effects of kinin B1 (Sar[D-Phe8]-des-Arg9-BK; 10 nmol/kg) and B2 (bradykinin (BK); 10 nmol/kg) receptor agonists on plasma extravasation in selected rat tissues; (b) determine the contribution of a lipopolysaccharide (LPS) (100 microg/kg) to the effects triggered by B1 and B2 agonists; and (c) characterize the selectivity of B1 ([Leu8]desArg9...

Sodium channels consist of a pore-forming a subunit and auxiliary b1 and b2 subunits. The subunit b1 alters the kinetics and voltage-dependence of sodium channels expressed in Xenopus oocytes or mammalian cells. Functional modulation in oocytes depends on speci®c regions in the N-terminal extracellular domain of b1, but does not require the intracellular C-terminal domain. Functional modulation...

The effects of various inducers on the activities of drug-metabolizing enzymes including aflatoxin B1 activation were studied in Syrian golden hamsters. Activity for aflatoxin B1 was determined by aflatoxin B1-DNA adducts formation. The treatments of hamsters with 3-methylcholanthrene, alpha-naphthoflavone and benzo(a)pyrene elevated markedly the activity for aflatoxin B1 by 2460, 1380 and 450%...

1.16. Again, I’ll only do the triangle inequality. Let x = (a1, . . . , an), y = (b1, . . . , bn), z = (c1, . . . , cn) be three points in Rn, then there is some integer j, 1 ≤ j ≤ n where the max occurs, so that d∞(x, y) = |aj − bj |. Hence, d∞(x, y) = |(aj−cj)+(cj−bj)| ≤ |aj−cj |+|cj−bj | But, |aj−cj | ≤ max{|a1− c1|, . . . , |an − cn|} = d∞(x, z), since it is one of the terms occurring in th...

Vitamin B1 is a watersoluble vitamin. It consists out of a pyrimidineand a thiazol ring, which are synthesized independently and linked afterwards.Vitamin B1 is de novo produced by many plants and microorganisms. Humans and animals have to take it up by nutrition. They are only able to do the phosphorylation reaction of the thiamin molecule. Thiamin is found free and as mono-, diand triphosphat...

THE TITLE COMPOUND [SYSTEMATIC NAME: 1,5-dihydr-oxy-3,6-dimeth-oxy-4-(2-methyl-but-3-en-2-yl)-9H-xanthen-9-one], C(20)H(20)O(6), is a xanthone, which was isolated from the roots of Cratoxylum formosum ssp. pruniflorum. The three rings in the mol-ecule are approximately coplanar, with an r.m.s. deviation of 0.0372 (2) Å for the plane through the 14 non-H atoms. The O atoms of the two hydr-oxy su...

Interaction of the Eph family of receptor protein tyrosine kinases and their ligands, ephrin family members, induces bi-directional signaling via cell-cell contacts. High expression of B-type ephrin is associated with high invasion potential of tumors, however, the mechanism by which ephrin-B promotes cancer cell invasion is poorly understood. We show that interaction of ephrin-B1 with the Eph ...
