The seasonal variation of 25-hydroxycholecalciferol and 1,25-dihydroxycholecalciferol was analyzed in 240 elderly subjects (mean age: 78 yr) in Belgium. Serum 25-hydroxycholecalciferol was lowest from February until May (mean levels less than 25 nmol/L). S ...
The side chain of 4-allylphenols was easily deprotonated by BuLi-KOCMe3. Consecutive treatment with FB(OMe)2 and H2O2 afforded the title alcs. I (R = H, R1 = H, OMe; R = R1 = OMe). [on SciFinder (R)] ...
The drinking water standard or maximum contaminant level (MCL) for arsenic is currently being re-evaluated by the US Environmental Protection Agency. The health risk associated with exposure to arsenic through consumption of drinking water is a primary con ...
Human retinol-binding protein (RBP) is a monomeric 21-kDa protein that is currently the subject of numerous studies owing to its role in the cellular uptake and utilization of retinol. When the RBP gene is overexpressed in Escherichia coli, inclusion bodie ...
An in vitro model, designated the Simulator of the Human Intestinal Microbial Ecosystem (SHIME), was used to study the effect of a soygerm powder rich in beta-glycosidic phytoestrogenic isoflavones on the fermentation pattern of the colon microbiota and to ...
The pentose phosphate pathway and the pyruvate shunt were identified as major pathways of glucose catabolism in a recombinant, riboflavin-producing Bacillus subtilis strain. Reactions connecting the tricarboxylic acid cycle and glycolysis, catalyzed by the ...
Hydrogel membranes formed by interfacially photopolymerizing poly(ethylene glycol) (PEG) diacrylate precursor solution were prepared from PEG diacrylate of molecular weights (MW) ranging from 2000 (2K) to 20000 (20K) with concentrations ranging from 10% to ...
Continuous cultivation in a glucose-limited chemostat was used to det. the growth parameters of wild-type Bacillus subtilis and of a recombinant, riboflavin-producing strain. Maintenance coeffs. of 0.45 and 0.66 mmol of glucose g-1 h-1 were detd. for the w ...
The effects of subclinical vitamin D deficiency and vitamin D supplementation on oral glucose tolerance and secretion of pancreatic hormones were studied in 10 diphenylhydantoin-treated epileptic patients and 15 geriatric patients. Their mean serum concent ...
The serum concentrations of calcium, phosphorus, parathyroid hormone, vitamin D3 metabolites and their transport protein (DBP) were measured in 18 patients with the nephrotic syndrome (mean daily proteinuria 8.8 g). The glomerular filtration rate was norma ...
