A simple, precise, accurate, and validated reverse-phase HPLC method was developed for the determination of melamine in milk (pasteurized and UHT milk) and dairy products (powdered infant formula, fruit yogurt, soft cheese, and milk powder). Following extraction with acetonitrile:water (50:50, vol/vol), samples were purified by filter (0.45 μm), separated on a Nucleosil C8 column (4.6 mm × 250 ...

Introduction . The storage of pond ash at dumps has a negative impact on the environmental situation in nearby settlements, constantly dust and pollute water sources. To solve this problem, it is proposed to use from as component mixed binder. Since specific surface area different throughout dump, necessary study its influence strength set binder under curing conditions. Materials methods equip...

BACKGROUND Iosimenol 340 injection is a new isotonic iodinated contrast medium for X-ray angiography. PURPOSE To investigate the pharmacokinetics and biotransformation, tolerability, and safety of Iosimenol 340 in healthy human subjects. MATERIAL AND METHODS Twenty-four subjects were enrolled and randomized to receive either Iosimenol 340 (0.5, 1.5 or 3.0 mL/kg) or placebo (0.9% saline). In...

Colorectal cancer represents one of the most challenging diseases. Increasing evidence indicates that aberrant expression of microRNAs (miRNAs) is related to pathogenesis of colorectal cancer. Cancer cells reprogram metabolic pathways to sustain higher proliferation rates. Whether mechanisms underlying the role of miRNA in colorectal cancer are in...

We describe a novel method for determining serum triglycerides, in which an enzymatic hydrolysis replaces the more commonly used saponification procedure. Under the conditions of the assay, the enzymatic hydrolysis can be completed in less than 10 mm by the combined action of a microbial lipase and a protease. We have been able to demonstrate complete hydrolysis of triglycerides by thin-layer c...

We study Na2IrO3 by angle-resolved photoemission spectroscopy, optics, and band structure calculations in the local-density approximation (LDA). The weak dispersion of the Ir 5d-t(2g) manifold highlights the importance of structural distortions and spin-orbit (SO) coupling in driving the system closer to a Mott transition. We detect an insulating gap Δ(gap)≃340  meV which, at variance with a Sl...

The Medicago truncatula expressed sequence tag (EST) database (Gene Index) contains over 140,000 sequences from 30 cDNA libraries. This resource offers the possibility of identifying previously uncharacterized genes and assessing the frequency and tissue specificity of their expression in silico. Because M. truncatula forms symbiotic root nodules, unlike Arabidopsis, this is a particularly impo...
