BACKGROUND Few studies have been done of bone densities in humans receiving retinoids, despite a substantial amount of literature concerning retinoid-induced osteoporosis in animals. We prospectively measured bone density and calcium metabolism in young men (aged 17-25 years) receiving oral isotretinoin for cystic acne and in a group of healthy volunteers (aged 19-26 years). OBSERVATIONS Comp...

BACKGROUND Atrial fibrillation (AF) shortens the atrial effective refractory period (ERP) and predisposes to further episodes of AF. The acute changes in atrial refractoriness may be related to tachycardia-induced intracellular calcium overload. The purpose of this study was to determine whether digoxin, which increases intracellular calcium, potentiates the acute effects of AF on atrial refrac...

Extracellular laccase was produced by Trametes versicolor IBL-04 using corn cobs as a substrate under pre-optimized culture conditions. A 64kDa laccase enzyme was purified and immobilized on calcium alginate beads using glutaraldehyde as a cross-linking reagent. Maximum enzyme immobilization efficiency (89%) was observed with 2-mm calcium-alginate beads that were developed using 4% (w/v) sodium...

Humidity influences the tribological performance of the head-disk interface in magnetic data storage devices. In this work a quartz crystal microbalance was used to measure the uptake of water on amorphous hydrogenated carbon (a-CHx) films at room temperature and pressures of water corresponding to relative humidities of 25%: These experiments have used a-CHx films of varying thickness with and...

Acetate accumulation during the fermentation process of Escherichia coli FB-04, an L-tryptophan production strain, is detrimental to L-tryptophan production. In an initial attempt to reduce acetate formation, the phosphate acetyltransferase gene (pta) from E. coli FB-04 was deleted, forming strain FB-04(Δpta). Unfortunately, FB-04(Δpta) exhibited a growth defect. Therefore, pta was replaced wit...

Objective: Development and validation of a quick and easy screening tool for the early detection of undernourished residents in nursing homes and residential homes. Design: Multi-center, cross sectional observational study. Setting: Nursing homes and residential homes. Participants: The screening tool was developed in a total of 308 residents (development sample; sample A) and cross validated i...

FUKUOKA, Y., OKUDA, T. and TACHIBANA, T. Variance in the Activity o f the Fourth Component of Mouse Complement. Tohoku J. exp. Med., 1983, 141 (2), 225-235 There are two methods for hemolytic titration of 04. One is a method using EACIgP, °XyC2hu and EDTA-CSP (E-C method) and the other using EACIgP, oxyC2hu and C4DSP (C4D mehtod). The 04 titers obtained by these two methods differed depending o...

IAEA BULLETIN, 42/1/2000 N uclear applications in health care have a timehonoured record of being highly cost-effective in addressing important health problems such as malnutrition, cancer, infectious and circulatory diseases. Today they are providing lasting benefits for patients, physicians, medical researchers, and health care practitioners throughout the world. Many nuclear applications hav...
