Using mitochondrial DNA restriction endonuclease analysis, the dynamics of the natural Saccharomyces cerevisiae strains present in spontaneous wine fermentations have been studied. We observed a sequential substitution of Sacch. cerevisiae strains along fermentation agreeing with different fermentation phases. When the restriction pattern's similarity (measured as the fraction of shared restric...
gbv-c از اعضای خانواده فلاوی ویریده بوده و به تازگی پیشنهاد شده که در جنس جدیدی در این خانواده بنام پگی ویروس طبقه بندی شود. انتشار جهانی این ویروس شایع بوده تا جایی که، بعضی مطالعات یک چهارم جمعیت انسانی را آلوده به این ویروس می دانند. راه های انتقال این ویروس از مسیر خون و فرآورده های آن، مادر به جنین و با میزان بسیار بیشتر نسبت به سایر مسیرها، از طریق جنسی است. از آنجا که راه انتقال این ویرو...

This experiment was conducted to compare the qualitative feed restriction and meal feeding on the performance, carcass yield and Ascites syndrome in Ross-308 broiler chickens. One hundred eighty day-old chicks raised for 42-d in a completely randomized design with five treatments, three replicates and 12 chicks per each pen. Experimental treatments included: 1) ad-libitum intake, 2) ad-libitun ...
the aim of present study was to investigate whether food restriction combined with exercise training could attenuate the oxidative stress and promote angiogenesis in a rat model of heart failure. 50 male wistar rats weighing 250-300 g were randomly divided into 5 groups including: 1) sham; they were fed ad libitum food, n=10. 2) heart failure group; 3) exercise group; they run on a treadmill 5 ...
background: to identify the fasciolid species by morphometric and molecular methods in zanjan, northwest of iran. methods : adult fasciola worms (n=584) were obtained from cattle and sheep in zanjan slaughterhouse in 2007. living flukes were washed, then worms' images were taken by 3ccd camera and finally apical zone of each worm was obtained. morphometric values such as body length, body widt...
