INTRODUCTION Prolonged treatment with levothyroxine 4 (L-T4) is a well known risk factor for osteoporosis. Patients on L-T4 replacement occasionally have a subnormal TSH, which carries a risk of development of bone loss. Thyroid hormones directly affect bone cells, stimulating osteoclastic and osteoblastic activity with a predominance of bone resorption and decrease of bone mineral density (BMD...

Classical treatment of cell attachment by models of filtration or coulombic attraction assumes that attachment of cells to mineral surfaces would be controlled by factors such as response to predation, collision efficiency, or coulombic attraction between the charged groups at the mineral and cell surfaces. In the study reported here, the passive model of attachment was investigated using a nat...

Controlling for body size and composition, the authors examined the association between estrogen therapy and bonemineral density in older African-American andCaucasian women. In 1992–1998, 443 African-American and 989 Caucasian women aged 45–87 years were assessed for medication use, laboratory variables, behavioral characteristics, and bone mineral density. The mean age was 61.3 (95% confidenc...

the aim of this study was to determine the fatty acid and mineral composition in bone of 3 pelagic fish: gold stripe sardine (sardinella gibbosa), anchovy kilka (clupeonella engrauliformis) and indian anchovy (stolephorus indicus). fatty acid profiles showed that total saturated fatty acid have no significant differences in 3 species. the content of total mono saturated fatty acids in anchovy k...

Roasted and non roasted full fat or partially defatted flaxseed flours (Linum Usitatissimum) were evaluated for their proximate composition, mineral profile and functional properties. Significant increase in the crude protein, crude fiber, ash and mineral contents in the partially defatted flaxseed flours (both roasted and non-roasted) was observed. Partial defattening improved the foam capacit...

In this paper we describe our study on the characterization of cigarette samples according to their mineral content. Acid digestion assisted by microwaves was employed, and inductively coupled plasma optical emission spectrometry was the analytical technique used for the determination of Al, Ba, Ca, Cu, Fe, K, Mg, Mn, Na, P and Sr in conventional, light, and flavorized cigarettes. Multivariate ...

The bark of some medicinal trees (Alstonia boonei, Pycnanthus angolensis, Anacardium occidentale, Mangifera indica, Khaya iroresis, Nauclea diderichii, Morinda lucida and Bridelia micrantha) found in Nigeria were analysed for mineral composition and phytochemical screening. The mineral composition were determined and found to contain some elements such as sodium, potassium, calcium, magnesium, ...

The aim of this study was to evaluate the impact of a community-based exercise program on bone mineral density and body composition in postmenopausal women with pre-diabetes and type 2 diabetes. Twenty postmenopausal women (aged 61.3 ± 6.0 years) with pre-diabetes and type 2 diabetes were randomly assigned to a community-based exercise program group (n=10) or a control group (n=10). The communi...

koenenite=[mg7ai4(oh)22]4+.[na4(ca,mg)2ci12]4- , is a typical non-silicate clay mineral of oceanic salt deposits which also widely occurs in salt clay, anhydrite, halite, and potash-bearing rocks. koenenite is found as an undesirable sludge-forming component in the processing of potassium salts . koenenite was first reported, in 1902, as an impurity in a fairly pure halite from the justus! pota...
