BACKGROUND An understanding of tooth enamel mineral content using a clinically viable method is essential since variations in mineralization may serve as an early precursor of a dental health issues, and may predict progression and architecture of decay in addition to assessing the success and effectiveness of the remineralization strategies. MATERIAL AND METHODS Twenty two human incisor teet...

1. The skeletal effects of physical training were studied in a controlled trial involving 31 healthy women (aged 50-73 years) with previous Colles' fracture of the forearm. The bone mineral content of the lumbar spine and both distal forearms was measured by dual-photon (153Gd) absorptiometry. 2. The participants were allocated to either a physical exercise group or a control group. The former ...

We studied the effects of dietary mineral source and oil intake on kidney calcification in 4-wk-old female Fischer rats after consuming the AIN-76 purified diet (AIN-76). A modified AIN-76 mineral mixture was used, although the original calcium (Ca)/phosphorus (P) molar ratio remained unchanged. Rats were fed the modified diets for a period of 40 d before their kidneys were removed on the last ...

BACKGROUND Enamel is the hardest and the stiffest tissue in the human body. The enamel undergoes multidirectional stresses, withstands multimillion chewing cycles, all while protecting the internal dentin and pulp from damage due to mechanical overload and exposure to the harsh chemical environment of the mouth. Raman spectroscopy allows to study enamel mineral content in a non-destructive and ...

OBJECTIVE To determine the effectiveness of vitamin D supplementation for improving bone mineral density in children and adolescents and if effects vary with factors such as vitamin D dose and vitamin D status. DESIGN Systematic review and meta-analysis. DATA SOURCES Cochrane Central Register of Controlled Trials, Medline (1966 to present), Embase (1980 to present), CINAHL (1982 to present)...

Spinal trabecular bone mineral content was measured in the first, second, and third lumbar vertebrae by quantitative computed tomography in 88 patients with non-steroid treated rheumatoid arthritis. Results were compared with those obtained in 105 healthy control subjects. The mean bone mineral content in the patient group, 135.8 (SD 32.8) mg/ml K2HOP4, was significantly lower than that in the ...

Osteoporosis in laying hens has been a production and welfare concern for several decades. The objective of this study was to determine whether differing opportunities for exercise during pullet rearing influences long-term bone quality characteristics in end-of-lay hens. A secondary objective was to assess whether differing opportunities for exercise in adult housing systems alters bone qualit...

Investigation into proximate and mineral content of three commercially important fish species (Lates niloticus, Clarias anguillaris and Hemisynodontis membranaceus using the traditional smoked method was conducted. Proximate analysis showed significant differences (P< 0.05) among the fish samples. However, there was no significant difference in their mineral content. Crude protein in fish sampl...

As more data are accumulated it becomes increasingly evident that great variations exist in the mineral content of different samples of the same foodstuff. Only when a large number of samples from different parts of the country have been analyzed will it be possible to approximate the probable mineral content of our diet. With the data now available it is difficult to draw any safe conclusion a...
