The GLIMPSE and MSX surveys have been used to examine the mid-infrared properties of a statistically complete sample of 6.7 GHz methanol masers. The GLIMPSE point sources associated with methanol masers are clearly distinguished from the majority, typically having extremely red mid-infrared colors, similar to those expected of low-mass class 0 young stellar objects. The intensity of the GLIMPSE...

The possibility of separating divinyl from the butene-divinyl fraction by method extractive distillation is considered. A comparative evaluation process was performed using methanol and acetonitrile as agents

background and objectives: iran owns a rich and prestigious heritage of medicinal herbs but the majority of these plants have not yet undergone chemical, pharmacological and toxicological studies. in the present study some species form northern parts of iran were evaluated for cytotoxicity. methods: sixteen medicinal plants were extracted with methanol and screened for their cytotoxic activitie...

Persea americana is a plant used by traditional medicine practitioners to treat ailments including diarrhoea and diabetes mellitus in Nigeria. Hence, the chloroform and the methanol fractions of the chloroform-methanol extract of the leaves of P. americana were evaluated for their acute toxicity as well as anti-diarrhoeal effects in Wistar rats to substantiate this claim. The chloroform and met...

A preculture of S. halstedii 2723-SV2 was inoculated into three 50-liters jar fermentors containing 27 liters of the culture mediumconsisting of glycerol 2%, molasses 1%, casein 0.5%, polypepton 0.1% and CaCO3 0.4% (pH 7.0 before sterilization), and fermentation was carried out at 27°C for 24 hours with agitation at 150 rpm and an air flow at 30 liters/minute. Nerfilin I was purified from the s...

The aim of this study was to assess the sperm quality and testicular histomorphometry of Wistar rats supplemented with extract and fractions of fruits of Tribulus terrestris L. The ethanolic extract was obtained by dynamic maceration of spray-dried fruit. This extract was fractionated by liquid-liquid partition, using increasing polarity solvents. Twenty male rats were separated in four groups,...

A diet rich in polyphenols has previously been shown to be associated with a lower risk for cardiovascular disease. Specifically, inhibition of platelet hyperactivation by polyphenols decreases platelet-dependent thrombosis, reducing the risk for cardiovascular disease. However, whether polyphenols in Salvia miltiorrhiza Bunge (SMB) affect platelet functions has not been clearly determined. Her...

BACKGROUND In Pakistan Fagonia olivieri (Zygophyllaceae) is commonly used in the indigenous system of medicine for treatment of conditions like diabetes, cancer, fever, asthma, toothache, stomach troubles and kidney disorders. This study evaluated the crude methanol extract of F. olivieri (FOM) and its derived fractions for their antimicrobial and cytotoxic activities as well as the classes of ...

plants re-emit a substantial fraction of their assimilated carbon into the atmosphere as biogenic volatile organic compound. according to the presence of relatively high amount of methanol in herbal distillates, finding different concentrations of ethanol in such drinks is expectable, as several studies appeared that produced ethanol by plants emits into the atmosphere as do methanol. in this s...
