Dependence of betaine stimulation of vitamin b(12) overproduction on protein synthesis.

Applied and environmental microbiology

Fa YH, Kusel JP, Demain AL.
PMID: 16346536
Appl Environ Microbiol. 1984 May;47(5):1067-9. doi: 10.1128/aem.47.5.1067-1069.1984.

The betaine-stimulated differential synthesis of vitamin B(12), i.e., the increase in B(12) per increase in dry cell weight, by Pseudomonas denitrificans was inhibited by rifampin and chloramphenicol but not by benzylpenicillin and carbenicillin at concentrations of antibiotic that inhibit...

Neurologists' evaluation and treatment of hyperhomocysteinemia in stroke patients.

Journal of stroke and cerebrovascular diseases : the official journal of National Stroke Association

Bushnell CD, Goldstein LB.
PMID: 17904008
J Stroke Cerebrovasc Dis. 2005 May-Jun;14(3):101-6. doi: 10.1016/j.jstrokecerebrovasdis.2005.01.003.

Observational study data have suggested that neurologists preferentially selected younger patients with generally few traditional stroke risk factors for homocysteine testing. The aim of this study was to corroborate observational data by assessing neurologists' reported practices for the detection...

Charge-transfer mechanism in Pt/KTa(Zr)O(3) photocatalysts modified with porphyrinoids for water splitting.

Chemistry (Weinheim an der Bergstrasse, Germany)

Hagiwara H, Inoue T, Kaneko K, Ishihara T.
PMID: 19834939
Chemistry. 2009 Nov 23;15(46):12862-70. doi: 10.1002/chem.200901772.

The mechanism of photocatalytic splitting of H(2)O into H(2) and O(2) on Pt/KTa(Zr)O(3) modified with various porphyrinoids was investigated. The photocatalytic activity of KTaO(3) catalysts is improved by dye modification. Cyanocobalamin (vitamin B(12)) is the most effective for improving...

Vitamin B(12)-TiO(2) heterogeneous hybrid catalyst (B(12)-TiO(2)) mediated ring-expansion reactions and their reaction mechanism were clarified by various spectroscopic methods. Diffuse reflectance UV/VIS (DR-UV/VIS) studies showed that B(12)-TiO(2) was activated to form the supernucleophilic Co(I) species of B(12) by irradiation...

5-Methyltetrahydrofolate (5-MTHF) is the predominant form of folate and a strong determinant of homocysteine concentrations. There is evidence that suboptimal 5-MTHF availability is a risk factor for cardiovascular disease independent of homocysteine. The analysis of folates remains challenging and...
