Several reports have shown the various effects of grape (Vitis vinifera) seed extract such as antioxidant, hypotensive, hypolipidemic and vasodilatory effects. The aim of present study was to investigate the effect of grape leaf hydroalcoholic extract on isolated rat tracheal contractions induced by KCl and acetylcholine. The trachea was removed from male adult Sprague-Dawley rat and placed in ...

In recent years, increasing in the level of public health consciousness has led to a drastic decrease in the use of synthetic food preservatives. Therefore, there has been a growing demand for novel antimicrobials. Apart from that, finding low cost sources has been always an important issue for food marketers. The present study was designed to investigate in-vitro antibacterial activities of gr...

MOTIVATION The avalanche of data arriving since the development of NGS technologies have prompted the need for developing fast, accurate and easily automated bioinformatic tools capable of dealing with massive datasets. Among the most productive applications of NGS technologies is the sequencing of cellular RNA, known as RNA-Seq. Although RNA-Seq provides similar or superior dynamic range than ...

Seven treatments (activated charcoal, bentonite, PVPP, yeast cell walls, potassium caseinate, zeolite and grape seed oil) were evaluated for their efficacy in decreasing the concentration of geosmin, responsible for earthy off-flavour in wine. In the red wine the potassium caseinate and grape seed oil treatments decreased the concentration of geosmin by 14% and 83%, respectively, while in the w...

In this study, a water quality model of Haraz basin was used as an evaluative tool to estimate the spatial distribution of variables that are related to water quality and nutrient loads of the Haraz River. Previous studies performed in this river indicate that trout culture activity along the Haraz River have led to various changes in the water quality parameters. In the present work, the possi...
