In France, despite the ban of meat-and-bone meal (MBM) in cattle feed, bovine spongiform encephalopathy (BSE) was detected in hundreds of cattle born after the ban. To study the role of MBM, animal fat, and dicalcium phosphate on the risk for BSE after the feed ban, we conducted a spatial analysis of the feed industry. We used data from 629 BSE cases as well as data on use of each byproduct and...

The apparent calcium (Ca) digestibility coefficient (ADC) and true (TDC) of different inorganic sources were determined in laying hens ages. Three Ca tests carried out, each assessing 240 Lohmann Brown lineage distributed a completely randomized design. Nine dietary treatments arranged 3 × factorial design consisting three ages (40, 50 70 weeks) (dicalcium phosphate (DCP) sources, fine (FL) coa...

The title compound, Ca2+x Nd8-x (SiO4)6O2-0.5x (x = 0.49), was synthesized at 1873 K and rapidly quenched to room temperature. Its structure has been determined using single-crystal X-ray diffraction and compared with results reported using neutron and X-ray powder diffraction from samples prepared by slow cooling. The single-crystal structure from room temperature data was found to belong to t...

AIM Skeletal muscle fatigue is characterized by a failure to maintain force production or power output during intense exercise. Many recent studies on isolated fibres have used brief repetitive tetanic contractions to mimic fatigue resulting from intensive exercise and to investigate the underlying cellular mechanisms. Such studies have shown that characteristic changes in Ca2+ regulation occur...

Diabetes mellitus is associated with a decrease in bone mineral content and increased urinary excretion of calcium and phosphate. The purpose here was to elucidate the pathogenesis of these changes by comparing serum calcium fractions of diabetics and healthy controls. In a cross-sectional study, serum ionized calcium at pH 7.40, [Ca2+]7.4, of 46 insulin-treated diabetics was decreased in compa...

1 These ingredients are nonmonograph except when used to prepare acidulated phosphate fluoride treatment rinses identified in § 355.10(a)(3) of this chapter. for marketing. In the absence of an approved new drug application or abbreviated new drug application, such product is also misbranded under section 502 of the act. (c) Clinical investigations designed to obtain evidence that any drug prod...
