. Introduction In 1988, closely spaced samples of glacial sediments were collected around known gold mineralization in the Turquetil-Maguse Lake region of southern District of Keewatin. As part of this project, several thousand archived samples, from both detailed and regional drift sampling programs carried out between 1970 and 1975 in the same region, were reanalyzed for a wide range of eleme...

INTRODUCTION Calcium hydroxide has been extensively used as the gold standard for direct pulp capping in clinical dentistry. It induces proliferation, migration, and mineralization in dental pulp stem cells (DPSCs), but the underlying mechanisms are still unclear. The aim of this study was to investigate the role of the mitogen-activated protein (MAP) kinase pathway in calcium hydroxide-induced...

This article describes the characteristics of gold–sulfide–quartz and gold–sulfide (gold–arsenic) ore occurrences in Manitanyrd region Polar Urals. Ore are confined to NE-trending shear zones have common features a geological structure. The host rocks metamorphosed volcanic volcanic–sedimentary rocks. We analyzed mineral chemical composition mineralization all studied occurrences, showing that ...

In this thesis, interaction of ferritin with transition metal ions and chelates is studied. First, a simple method for synthesizing gold nanoparticles stabilized by horse spleen apoferritin (HSAF) was reported using NaBH4 or 3-(N-morpholino)propanesulfonic acid (MOPS) as the reducing agent. The average particle diameters were 3.6 and 15.4 nm for NaBH4-reduced and MOPS-reduced Au-HSAF, respectiv...

Abstract As a result of the analysis data available and collected in recent years, contrast to well-established ideas about polygenic poly-stage nature mineralization, it is indicated that gold mineralization Central Kyzyl Kum formed as formation single ore-magmatic system, which develops same type regardless composition age host rocks; during deposits, most important thing presence process pro...
