introduction: osteoporosis is a multifactorial disease and several factors are involved in development and progression of the disease. the aim of this study was to increase our understanding of the relation between age, weight, bmi, postmenopausal age and bone mineral density in post menopause women. methods: 240 azarbaijani women aged 50-70 years having inclusion criteria were recruited. bone ...

a brief account of the representative and workable industrial minerals namely magnesite, talc and barite in lesser himalaya, is presented here emphasizing their genesis. deposits of magnesite and talc are found associated with neoproterozoic, plateform type, shelf-slope limestone-dolomite host rocks from inner lesser himalayan sequences. field, textural, geochemical signatures and fluid inclusi...

samples of formalin fixed gastrointestinal organs of three month ostrich chicks were submitted to the department of pathology, razi vaccine and serum research institute. histologically hepatitis and pancreatitis with large eosinophilic intra nuclear inclusion bodies were prominent in hepatic and pancreatic cells. these inclusions were suspected as adenovirus inclusion body hepatitis (ibh) in va...

Defined mixtures of two grass (orchardgrass, perennial ryegrass) and two legume (alfalfa, red clover) hays, harvested in two cuttings in 2 yr, were fed in digestibility, intake and mineral balance trials to wether lambs. Each mixture was fed in ad libitum amounts to six crossbred wether lambs weighing 35 to 45 kg. The effect of increasing proportion of legume in mixtures on dry matter digestibi...

Abstract This review summarises the current knowledge of mineral nutrition for penaeid shrimp. It investigates how aquatic environment and lifecycle shrimp affect requirements role that minerals play in health. Methods supplying via either water or to feed, novel ways supplementing within are discussed. The individual summarised with recommendations minimum levels dietary inclusion semi‐intensi...

Correlations between particulate organic carbon (POC) and mineral fluxes in the deep ocean have inspired the inclusion of "ballast effect" parameterizations in carbon cycle models. A recent study demonstrated regional variability in the effect of ballast minerals on the flux of POC in the deep ocean. We have undertaken a similar analysis of shallow export data from the Arctic, Atlantic, and Sou...

[1] Atmospheric mineral aerosols influence climate and biogeochemistry, and thus understanding the impact of humans on mineral aerosols is important. Our longest continuous record of in situ atmospheric desert dust measurements comes from Barbados, which shows fluctuations of a factor of 4 in surface mass concentrations between the 1960s and the 1980s [Prospero and Nees, 1986]. Understanding fl...

Minerals can readily bind to phytic acid and thus have the potential to form mineral±phytate complexes that may be resistant to hydrolysis by phytase activity of animal, plant and microbial origin. In simple solution, at pH 7.0, mineral concentrations from 0.053 mM for Zn up to 4.87 mM for Mg caused a 50% inhibition of phytate-P hydrolysis by microbial phytase. The rank order of mineral potency...

Microorganisms are ubiquitous in the shallow subsurface often attached to sediment surfaces where they alter the geochemical microenvironment and mediate weathering reactions. Microbial attachment on sediment grains, however, is heterogeneous and the variability of microbial occurrence cannot be easily explained. This study examined how phosphate mineral and iron oxide inclusions in feldspars i...
