DESCRIPTION GLYSET Tablets contain miglitol, an oral alpha-glucosidase inhibitor for use in the management of non-insulin-dependent diabetes mellitus (NIDDM). Miglitol is a desoxynojirimycin derivative, and is chemically known as 3,4,5-piperidinetriol, 1-(2­ hydroxyethyl)-2-(hydroxymethyl)-, [2R-(2α,3β,4α, 5β)]-. It is a white to pale-yellow powder with a molecular weight of 207.2. Miglitol is ...

A condition evidenced by retarded growth of wool with alteration of the yolk into a yellow, sticky, wax-like substance was investigated. The condition was associated with hyperaemia and cellular infiltration into the dermis in the affected areas. Three bacterial species, viz. Enterobacter aerogenes, E. agglomerans and Hafnia alvei, which could grow on the water-extractable component of wool-yol...

PD/CC@SiO 2 core–shell nanoparticles (PD: perylene dye, CC: cholecalciferol/vitamine D 3 ) show high colloidal stability in water, intense emission from red to yellow with quantum yields near unity, and excellent photostability.

Esterification and transesterification of high free fatty acid (FFA) oils to fatty acid alkyl ester (FAAE) by sol-gel entrapped lipase B from Candida antarctica (CalB) and lipase from Burkholderia cepacia were investigated. The optimal conditions for the esterification catalyzed by the immobilized CalB were determined to be 50 °C, 1.7:1 molar ratio of methanol to fatty acid, and 0.36 g of water...

SYNOPSIS The statement made in some standard textbooksthatBenedict'squalitativetestgivesa green, yellow, or orange-red precipitate with pure solutions of glucose of varying strength has been shown to be incorrect. Pure solutions ofglucose give only a bright red precipitate at all concentrations. These changes in the colour of the suspensions are observed with urinary glucose only. The differenc...

The Zika virus, an Aedes mosquito-borne flavivirus, was first identified in 1947 in Rhesus Monkeys in a vegetative region of Africa known as Zika. It is closely related to other flaviviruses such as dengue, yellow fever, West Nile and Japanese encephalitis viruses and shares a similar symptomology, namely malaise, headache, flushing, nausea and vomiting. Zika’s distinguishing feature is a macro...

Variations in the concentrations of particulate heavy metals and fluxes into the sea in the Yellow River were examined based on observational and measured data from January 2009 to December 2010. A custom-built water elutriation apparatus was used to separate suspended sediments into five size fractions. Clay and very fine silt is the dominant fraction in most of the suspended sediments, accoun...

1. When suspended in slightly alkaline (pH 7.4 to 7.8) saline dilutions of clear, hemoglobin-free normal monkey serum, the virus of yellow fever from infected monkeys and from infected, but blood-free, mosquitoes, usually acts as if it were possessed of a positive electrical charge. 2. The virus tends to assume a negative charge in fluids having a slightly acid reaction. 3. The isoelectric poin...
