The objective was to evaluate the interaction of a trace mineral (TM) injection (Multimin 90) and a supranutritional concentration of dietary vitamin E (VITE) on performance, carcass characteristics and color stability of strip steaks from feedlot heifers. Prior to trial initiation, Angus × Simmental cross heifers (N = 48) were managed on a common diet supplemented to meet NRC recommendations (NRC, 2000). Heifers were stratified by BW and allotted to a 2 x 2 factorial arrangement: 1) no supplemental vitamin E and saline injection (CONT+SAL), 2) 1000 IU vitamin E/heifer·d-1 and saline injection (VITE+SAL), 3) no supplemental vitamin E and TM injection (CONT+MM), or 4) vitamin E and TM injection (VITE+MM)...

BACKGROUND: Numerous studies have indicated that obstructive sleep apnea syndrome (OSAS), may contribute to the development of metabolic syndrome (MetS) and diabetes. Moreover, OSAS has been associated with lowered vitamin D (Vit D) levels, but reports are inconclusive. Aim of the study was to compare Vit D levels according to the presence of MetS and its components in OSAS patients. METHODS: The presence of MetS was evaluated and serum 25-hydroxy vitamin D [25(OH)D] levels were measured in consecutive newly diagnosed, by polysomnography, subjects with OSAS...

Background: Epidemiologic and in vitro studies suggest independent linkages between poor folate and/or vitamin B-12 nutrition, genomic human papillomavirus (HPV) type 16 viral integration, and cancer. However, there is no direct evidence in vivo to support the causative role of poor folate nutrition in HPV16 integration into the cellular genome. Objective: We tested the hypothesis that folate deficiency enables the integration of HPV16 into the genome of HPV16-harboring keratinocytes, and could thereby influence earlier transformation of these cells to cancer in an animal model...

Background: Formate is produced in mitochondria via the catabolism of serine, glycine, dimethylglycine, and sarcosine. Formate produced by mitochondria may be incorporated into the cytosolic folate pool where it can be used for important biosynthetic reactions. Previous studies from our lab have shown that cobalamin deficiency results in increased plasma formate concentrations. Objective: Our goal was to determine the basis for elevated formate in vitamin B-12 deficiency...

Information is limited on the current vitamin B12 status of South Koreans, including the results of biochemical indices. The objective of this study was to assess vitamin B12 status with vitamin B12 intake, major food sources, and plasma vitamin B12 concentration in Korean adults. We hypothesized that vitamin B12 intake and status would be different between sex and age groups. Three consecutive 24-hour recalls and fasting blood samples were obtained from healthy 20- to 64-year-old adults (N=141). The dietary vitamin B12 intake of the men (10...
