A study of the antidiabetic activity of alcohol extract of Achras zapota Linn. (Hindi-Chiku) roots, each with a dose 20, 40, 80 g/Kg body wt. (BW) given orally to rats has been conducted, using the Glucose Tolerance Test Method. The administration of alcohol extract at various doses indicated that doses equivalent to the fresh material 80g/Kg BW gave the strongest decreasing activity, followed ...

NAD-linked alcohol dehydrogenase activity was detected in cell-free crude extracts from various propane-grown bacteria. Two NAD-linked alcohol dehydrogenases, one which preferred primary alcohols (alcohol dehydrogenase I) and another which preferred secondary alcohols (alcohol dehydrogenase II), were found in propane-grown Pseudomonas fluorescens NRRL B-1244 and were separated from each other b...

BACKGROUND Quorum sensing is the key regulator of virulence factors of Pseudomonas aeruginosa such as biofilm formation, motility, productions of proteases, hemolysin, pyocyanin, and toxins. The aim of this study was to explore the effect of the extracts from some medicinal plants on quorum sensing and related virulence factors of P. aeruginosa. MATERIAL AND METHODS Quorum sensing inhibitory ...

The aldehyde dehydrogenases from livers of the inbred mouse strains C57BL/6J, DBA/ZJ, and the F1 generation of the cross between these strains (C57BL/6J X DBA/2 J) have been purified over 60-fold. Alcohol dehydrogenase activity is not present in the purified enzyme preparation. Enzyme preparations from both strains and from the F1 cross specifically require NAD but can oxidize a variety of alde...

A simple, reliable and reproducible method, based on capillary electrophoresis (CE) with electrochemical detection (ED), for the determination of five active ingredients and three carbohydrates in extracts of Gastrodia rhizoma is described in this work. The main active ingredients are gastrodin, 4-hydroxybenzyl alcohol, vanillyl alcohol, 4-hydroxybenzylaldehyde and vanillin. Operated in a wall-...

Objective: Citrinin is a mycotoxin produced by several species of the genera Aspergillus and Penicillium and occurs mainly in food products and animal feed. Some scientific reports show a link between Citrinin and nephrotoxic and possibly a carcinogenic effect for humans. Methods: Samples collected by settling plates,in northern Iran and pure culture isolation performed till t...

Nowadays modified textiles, especially UV-protective, antibacterial and antimicrobial ones, have become the focus of great interest. In this study, several new UV absorbers, bis(indolyl)methane derivatives, were synthesized and grafted onto polyvinyl alcohol polymer (PVA). Their application properties on cotton-based textile materials were determined; the UV protection factor values of the modi...

A simple RNA isolation method based on hot borate and proteinase K was used to extract high-quality RNA from petals of daffodils (Narcissus pseudonarcissus L. 'Dutch Master'). The method was adapted from the isolation technique described by Wan and Wilkins (1994). A single isopropanol precipitation and ethanol wash replaced all the second day steps of the Wan and Wilkins procedure. The RNA isol...

Theanine is an amide exclusively present in tea and some fungi, and is an important bioactive component of tea. The bioactive effects of theanine include antitumour, anti-diabetic, antihypertensive, anti-stress activities, and the ability to improve cardiovascular and cerebrovascular diseases. It also has protective effect on nerve cells against damage induced by environmental neurotoxins as we...

Liver is a major metabolic organ affected by various toxins and chemicals. So the potential therapeutic agent is needed for the treatment of liver diseases. Natural products are the best source of remedies for the treatment of all diseases.The aim of our study was to investigate the effect of leaf extract of Coccinia indica against Alcohol combines with CCl4 and Paracetamol induced hepatotoxici...
