With the huge explored reserves of potash salts in Kazakhstan, there is still no production fertilizers, demand for which constantly growing. In this regard, research processing largest Chelkar deposit ore into fertilizers and an urgent problem. The article presents results washed decomposition with nitric acid suspension filtration. filtering properties granulometric composition insoluble resi...

Diets containing freeze-dried black raspberries (BRB) suppress the development of N-nitrosomethylbenzylamine (NMBA)-induced tumors in the rat esophagus. Using bioassay-directed fractionation, the anthocyanins in BRB were found to be the most active constituents for down-regulation of carcinogen-induced nuclear factor-kappaB and activator protein-1 expression in mouse epidermal cells in vitro. T...

We previously showed by in vitro experiments that the cysteine residue (Cys111) near the dimer interface is critical for monomerization and resultant aggregate formation of mutant Cu, Zn-superoxide dismutase (SOD1) protein, which is toxic to motor neurons in familial amyotrophic lateral sclerosis (ALS). To verify the importance of Cys111 in the mutant SOD1-associated ALS pathogenesis in vivo, w...

The toric residue is a map depending on n + 1 divisors on a complete toric variety of dimension n . It appears in a variety of contexts such as sparse polynomial systems, mirror symmetry, and GKZ hypergeometric functions. In this paper we investigate the problem of finding an explicit element whose toric residue is equal to one. Such an element is shown to exist if and only if the associated po...

Water-soluble proteinpolysaccharides, called PPL, can be extracted from bovine nucleus pulposus in yields of 45%, and from bovine nasal cartilage in yields of 37% of the dry tissue weight. From human costal cartilage only 7% can be extracted. The method used to separate PPL from each of the first two tissues into four distinct fractions separates the PPL of human costal cartilage into four frac...

We have investigated Mo and W isotope compositions in acid leachates and an insoluble residue from the Murchison carbonaceous chondrite. The new data reveal variable enrichments of sand r-process isotopes and demonstrate that several isotopically diverse presolar components are present in Murchison. The insoluble residue is enriched in s-process Mo and W, evidently due to the enrichment s-proce...

Chick embryos were sacrificed at intervals after simultaneous injection of BAPN and proline-C(14), the collagen separated into neutral salt-extractable and residue fractions, and total hydroxyproline and hydroxyproline specific radioactivity determined in each fraction. Extractable collagen, measured as hydroxyproline, increased markedly and had a higher specific activity in BAPN-treated embryo...

Edible insects are a potential and sustainable protein resource. Various extraction methods used to process edible insects. However, the residue fraction is discarded after because of its poor functional properties, despite having high content. This study was conducted improve properties re-extracted from raw hydrolysed residues, demonstrate most effective condition buffer. Residues Hermetia il...
