BACKGROUND In the context of the search for cost-efficient treatments, Ulmo (Eurcyphia cordifolia) honey is an excellent alternative for treating burn wounds and could have a profound medical, social, and economic impact. Ascorbic acid is an enzymatic co-factor necessary for the synthesis of collagen and the proliferation of fibroblasts and has been proposed as a coadjuvant to strengthen the he...

Preparation of triphosphoinositide phosphodiesterase from brain extracts. The dialysed aqueous extract ofacetone-dried brain powder (Thompson & Dawson, 1964) was held in a water bath at 500 for 30 min. After cooling in an ice bath 0-25 vol. of 0(132 M-tris-HCl buffer, pH 7-2, was added. Saturated (NH4)2SO4 solution (neutralized to pH 7) at 40 was slowly added with stirring to give 30% saturatio...

in this study, both the presence and concentration of some unsaturated compounds in hexane extracts of different parts of anthemis talyschensis showing absorption at wavelength 280-450 nm were surveyed, with the view of possibly using extracts of this plant in new formulations of sunscreen creams. the hexane extracts of flower, leaf and stem of a. talyschensis , collected from northwest iran, w...

BACKGROUND Surfaces in congregate settings, such as vehicles used for mass transportation, can become contaminated with infectious microorganisms and facilitate disease transmission. We disinfected surfaces contaminated with H1N1 influenza viruses using hydrogen peroxide (HP) vapor at concentrations below 100 ppm and triethylene glycol (TEG)-saturated air containing 2 ppm of TEG at 25 degrees C...

Alternanthera bettzickiana (Regel) Nicolson is an erect herb and an ornamental pot plant, which is recorded to be useful in purifying and nourishing blood. It is also claimed to be a soft laxative, a galactagogue and an antipyretic in addition to its wound healing property. The leaves are reported to be used like spinach and in soups. The lipophilic acetone extract of the fresh flowers exhibite...

polarization for au/pb(zr ti )o /yba cu o ferroelectric capacitor has been studied and measured by pulse method. a sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional polarization curve is obtained by integrating the charge flow from the polarization switching induced by the voltage ramp. a value of 25?c/cm2 is measured for the saturated p...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...

This paper presents the results of a numerical study that examines the surface heating discrepancies observed between computed and measured values along a sharp cone. With Mach numbers of an order of 10 and the free-stream length Reynolds number of an order of 10 000, the present computations have been made with the direct simulation Monte Carlo (DSMC) method by using the G2 code of Bird. The o...

Background and objectives: Withania coagulans Dunal (Solanaceae) fruits are recommended to treat asthma, dyspepsia, biliousness, flatulent colic, liver complaints, intestinal infections, strangury, wounds and as diuretic, emetic and sedative agent in Indian traditional system of medicine. The objective of this study was to describe the systematic fatty acid composition...

The chemical screening carried out on Schizochytrium sp. biomass led the identification of 24 types of organic compounds belonging to n-alkanes, 1-alkenes, 1-alkanols, free fatty acids, methyl and ethyl esters of saturated and unsaturated fatty acids, saturated tri- and diglycerides, unsaturated monoglycerides, wax esters, sterols, triterpenes, and mono- and sesquiterpenes. Moreover, a sample c...
