The new strategy of tissue engineering, and regenerative medicine at large, is to construct biomimetic matrices to mimic nature's hierarchical structural assemblages and mechanisms of simplicity and elegance that are conserved throughout genera and species. There is a direct spatial and temporal relationship of morphologic and molecular events that emphasize the biomimetism of the remodeling cy...

Abstract The weathering of platinum-group element (PGE) deposits presents unusual problems, especially in the very active environment lateritic under tropical conditions. There is clear evidence destruction minerals (PGM) to form PGE oxides, or fine intergrowths between relict PGM and iron oxides hydroxides, as an intermediate stage during weathering. released by are transported solution with m...

The northern part of the Slanské Vrchy Mountains, in Slovakia, within territory Dubnik Opal Mines, is considered to be historical source opal, including opal known Romans. precious mineralization originating from post-magmatic hydrothermal fluids based on its values should recognized as an area global importance. Geological processes that are connected Neogene volcanic activity took place Mines...

The metabolism of ingested foods and orally administered drugs occurs in the hepato-gastrointestinal tract. This process is facilitated by several supergene families that catalyze oxidative metabolism as well as conjugation of the small molecular weight substances that enter the systemic circulation through resorption in the gastrointestinal tract. The catalytic action carried out by one of sev...

Abstract Published and unpublished iron isotope data from banded formations (BIF) their BIF-hosted hypogene (hydrothermal) ores the Quadrilátero Ferrífero (itabirites), Corumbá, Carajás districts in Brazil, as well Hamersley province Australia are presented discussed. BIF constitutes a typically thinly bedded or laminated chemical sedimentary rock, with ≥ 15% Fe layers of chert, chalcedony, jas...
