Murine Poliomyelitis in Vitamin B Deficient Mice
Nutrition as related to resistance and susceptibility to infection presmts two quite opposite notions. In time, the idea that the consumption of adequate and proper food provides the host with greater ability to resist infection, relates to periods of famine accompanied by pestilence, find precedes …

Insights into vitamin B₁₂ production, acquisition, and use by marine microbes
… essential aspects of marine biogeochemistry. Vitamin B₁₂, also known as cobalamin, is a cobalt containing organometallic micronutrient produced by some bacteria and archaea and required by many eukaryotic phytoplankton for methionine biosynthesis and regeneration. Although the potential for …

Determination of vitamin B₆ intake and transaminase activity in preadolescent girls
The vitamin B₆ nutriture of 8- to 10-year old girls living in southwest Virginia was investigated by determination of pyridoxine intake and measurement of serum glutamic oxalacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) activity. The 24-hour recall method was used to …

Influence of vitamin B-6 intake on vitamin B-6 status of lactating women and on the vitamin content of their milk: enzymatic, microbiological, and HPLC techniques
The influence of vitamin B-6 intake on vitamin B-6 status and the concentration of B-6 vitamers in milk of 21 white lactating women (21 to 35 years) was examined at 3 to 7 months postpartum. None of the women met the RDA for lactating women of 2.5 mg/day when considering vitamin B-6 intakes from …

Serum Vitamin B-12 Levels and Urinary Methylmalonate Excretion in Total Vegetarians
… was threefold: 1) to determine the present serum vitamin B-12 status in a select group of strict or total vegetarians all of whom had been vegetarian for six months or more. 2) to determine the daily intake of vitamin B-12, total calories, protein, % calories as fat, folic acid, and crude fiber on …

Vitamin B-6 content of selected foods after institutional cooking and holding procedures
The vitamin B-6 content of three foods, roast top round of beef in au jus, canned green beans in pot liquor, and whole baked potatoes was measured. These foods are typically served together as choices on the six week cycle menu at three dining halls on the University campus. Random samples were …

Analysis and Characterization of Vitamin B Biosynthesis Pathways in the Phytoparasitic Nematode Heterodera Glycines
… in the de novo biosynthesis and salvage of the B vitamins: B1, B5, B6, and B7. Each of these de novo pathways are believed to have been lost in most animals and their similarity to bacterial homologues made them candidates for horizontal gene transfer (HGT). Each gene had eukaryotic-like introns …

Mechanistic Studies of Vitamin B(12)-Catalyzed Dechlorination and Carbon-Carbon Bond-Forming Reactions
In the presence of catalytic vitamin B12 and a reducing agent such as TI(III)citrate or Zn, arylalkenes can be dimerized with unusual regioselectivity forming a new carbon-carbon bond between the benzylic carbons of each coupling partner. Dimerization products were obtained in good to excellent …

Characterization of horizontally transferred vitamin B biosynthesis genes in the soybean cyst nematode, Heterodera glycines
… recently. All these genes are involved in vitamin B biosynthetic pathways forming one complete and two partial pathways. They are potentially important molecular targets because there is evidence to show that these genes have been acquired through horizontal gene transfer from prokaryotes, …

Determination of vitamin B-6, available lysine and pyridoxyllysine in a new instant baby food product
… and 1987 were analyzed for available lysine, vitamin B-6 and pyridoxyllysine content. The available lysine content of 100 grams of baby food was found to be higher in the instant products, but when adjusted for protein content, available lysine was higher in the jar products. This indicates …

Vitamin B-6 status of a group of female adolescents: E-ALAT, microbiological, and HPLC methods
The vitamin B-6 status of 11 white adolescent females living in the Blacksburg/Roanoke, Virginia area was evaluated by dietary intakes, coenzyme stimulation of erythrocyte alanine aminotransferase (F-ALAT) activities, and plasma total vitamin B-6 measured microbiologically. Heights and weights of …

Development of a novel cyanide-free method for analysis of vitamin B₁₂ in milk-based infant formula
The analysis of vitamin B₁₂ in infant formulas requires the use of cyanide during the sample preparation process to convert the three unstable vitamers (hydroxocobalamin, methylcobalamin and adenosylcobalamin) to cyanocobalamin, the most stable form of vitamin B₁₂. The undesirable handling of …
