Mineral formation is regulated by molecular based promoters or inhibitors in biological systems. Among serum proteins, fetuin-A can effectively inhibit unwanted calcification vivo via forming fetuin-mineral complexes called calciprotein particles (CPPs). Here, the and phase transformation mechanisms of CPPs are investigated detail combining situ potentiometric measurements solid characterizatio...

carbonates are among the most common soil constituents in arid and semiarid zones. they exhibit many significant differences in their chemical and mineralogical, suite, origin, physical and micromorphological properties and consequently in their activities in soil. the differences cause different properties of calcareous soils. six profiles of aridisols and inceptisols with carbonate accumulati...

amygdaloidal, cavity- and fracture-filling zeolites in eocene volcanic rocks from the kuh-e-aradeh of southern kahrizak, in the northernmost part of central iran have been studied in some detail by optical, chemical analysis, sem, and xrd techniques. the zeolites identified, in order of their relative time of formation from early to late, are tetranatrolite, analcime, natrolite, mesolite, stilb...

The purpose of this study is to evaluate the mineral content, phenolic antioxidant activity, and soluble protein Lumi-lumi fish meal (Harpodon nehereus) treated with non-steamed for 30 min. results revealed that iron (Fe) content was significantly higher in steamed than treatment but not calcium (Ca). However, there a decrease minerals magnesium (Mg), phosphorus (P), zinc (Zn) during process, w...

Proterozoic limestone in a north British terrane contains newly recognised occurrence of Nb-REE minerals. The mineralized Loch Shin Limestone is the Lewisian Complex Northern Highlands Scotland, intruded by alkaline plutons above Caledonian (∼0.43 Ga) subduction zone. mineral assemblage includes columbite, calcium niobate minerals, and niobian rutile also W- Sn-bearing phases. interval between ...

Introduction: Fluid inclusions are micron-scale volumes of fluid entrapped during the precipitation of minerals. Fluids are entrapped during primary mineral growth, and during healing of later fractures. The water in fluid inclusions in minerals precipitated in the upper crust of Mars contains a record of the ambient environment during precipitation. This includes data on fluid temperature and ...

Since the antiquity, and on an empirical basis, man has accumulated experience on the benefits and risks of minerals (such as, special clay, mud and sand) and other mineral resources (such as, salt, sea water, spring water, underground water, volcanic emissions and dust) on human health. Man and minerals are chemical systems sharing a common composition, comprising major, minor and trace chemic...

Numerous reports have appeared in the Uterature purporting to show the value of phosphoritic minerals as calcium and phosphorus supplements in animal nutrition. A great variance exists between the results obtained by different investigators. Forbes and others (Oy have inferred that the fluorine content of these naturally occurring products was the cause of the harmful and variable results obtai...

Plants provide an important source of minerals for human and animal consumption. There is a general worldwide deficiency of human intake of several essential minerals, including iron, zinc, copper, calcium, magnesium, selenium, and iodine (White & Broadley, 2009). This deficiency exists not only in developing countries, but also in the developed world. On the other hand, excessive amounts of he...
