Toxicity has been associated with abuse of vitamin A supplements and with diets extremely high in preformed vitamin A. Consumption of 25,000-50,000 IU/d for periods of several months or more can produce multiple adverse effects. The lowest reported intakes causing toxicity have occurred in persons with liver function compromised by drugs, viral hepatitis,… (More)
Maintenance of a skeleton capable of resisting the stresses of everyday life is dependent on the mechanical forces applied to the skeleton during normal activity in a 1-G environment. When the effects of 1-G on the longitudinal skeleton are removed, as with space travel or inactivity, bone and bone mineral are lost because bone resorption is greater than… (More)
The purpose of this investigation was to examine white blood cell counts (WBC), immunoglobulin (IgA, IgG, IgM) levels, and T-cell proliferation following acute resistance training in 9 untrained (UT) and 6 trained (TR) women. Resistance training on 7 Universal machines at the subject's 10 repetition maximum (IORM) was performed at 89 +/- 5% for UT and 88… (More)
There are implications in the literature that wine is different from other alcoholic beverages and that it may even have a beneficial effect on the nutritional process. A metabolic study was undertaken in an attempt to document the effects of wine versus ethanol on absorption of various nutrients. Nitrogen and caloric data are presented here. During each of… (More)
Stimulation with the combination of PDB plus ionomycin induced LFA-1/ICAM-1-dependent homotypic adhesion of tonsil B cells. Adhesion of tonsil B cells in our system induced tyrosine phosphorylation of Pyk-2. Disruption of homotypic adhesion and concomitant inhibition of induction of protein tyrosine phosphorylation was achieved by physical separation of the… (More)
Six healthy young men participated in a metabolic balance study to assess the effects of wine versus ethanol on absorption of various elements. Zinc data are reported here. During each of four 18-day experimental periods, the subjects were fed a controlled diet plus 1 liter/day of one of the following test beverages, administered in random order: Zinfandel… (More)
Six healthy males were studied under metabolic unit conditions to determine the effects of wine vs ethanol on the absorption of various elements. Fluid, sodium, and potassium data are reported here. The following test beverages in the amount of 1 liter/day were administered in random order to each of the subjects during four 18-day experimental periods:… (More)
Healthy men with a daily intake of 0.37 mg fluoride were given dichloromethylene diphosphonate (Cl2MDP) or a placebo during a period of ambulation followed by bed rest. In both groups, serum ionic fluoride was unchanged, and fluoride balances were negative, but Cl2MDP significantly reduced loss of fluoride in the treated groups.
In a program of studies of disuse osteoporosis, fluoride balances were determined in healthy men during ambulation and then during bed rest for 6 to 17 wk. Control subjects ingested basal diets containing 0.4 mg fluoride per day, whereas experimental subjects received 10-mg fluoride supplements in divided doses with meals. Fluoride and calcium were measured… (More)
The I/O: Paper Prototyping for the Future studio will be a hands-on experience that combines art, design, and technology. Participants will learn through a series of escalating exercises how to introduce interactivity via computational crafting techniques to paper in order to heighten the paper prototyping experience.
