این تحقیق جهت تعیین میزان اسیدهای چرب اشباع و غیر اشباع در بافت 6 گونه میگوی دریایی و پرورشی شامل گونه های میگوی موزی(fenneropenaeus merguiensis)، ببری سبز(penaeus semisulcatus)، سفید هندی(fenneropenaeus indicus)، سرتیز(metapenaeus affinis)، خنجری(parapenaeopsis stylifera)و سفید غربی (litopenaeus vannamei)،انجام شد. استخراج روغن از بافت گوشت میگوها به روش bligh and dyer, 1959 و با استفاده از ...
Isooctane extraction of cells from Nocardia restrictus and Corynebacterium simplex followed by chromatographic separation gave yellow crystals which were identified as vitamin K2(35) by its ultraviolet absorption, nuclear magnetic resonance spectrum, and mass spectrometry. The purified vitamin K2(35) was found to stimulate steroid 1,2-dehydrogenase obtained from cell free extracts of N. restric...
Between 1976 and 1996 the fish of the Deep Fork River were sampled at three sites. A total of 163,358 specimens from 36 species was taken. To determine if changes had occurred since 1976 as a result of modifications in the aquatic environment, the fish communities at each of the three sampling stations were compared. Three periods during which well defined environmental changes that resulted in...
The aim of this study was to improve understanding of several factors related to the ecology and environmental risk of Borrelia infection in northern Florida. Small mammals and host-seeking adult ticks were collected at several sites, and specimens were tested for the presence of Borrelia species, primarily by PCR amplification. Tissues from some vertebrates and ticks were initially cultured in...
Three shrimps population (Penaeus semesulacatus, Penaeus japonicus,Meta Penaeus monoceros) were investigated for determination of the genetic structure by using (PCR-RAPD) and SDS-PAGE. The results obtained from RAPD technique showed the same percentages of similarity (100%) within the three studied population. On the other hand, the degrees of similarity detected by SDSPAGE were 90%, 87% and 8...

تاثیر بسته بندی تحتخلاء بر ماندگاری میگوی سفید سرتیز (Metapenaeus affinis) نگهداریشده با و بدون پوشش عصاره چای سبز (1 گرم بر لیتر) در طی نگهداری در یخچال (دمای 4 درجه سانتیگراد) به مدت 10 روز جهت اندازهگیری شاخصهای پراکسید، اسید تیوباربیتوریک، اسیدهای چرب آزاد، ملانوسیس (لکه سیاه) و خصوصیات حسی مورد مطالعه قرار گرفت. مقدار پراکسید، اسید تیوباربیتوریک و اسید چرب آزاد در میگوهای بستهبندی ش...
Ixodes scapularis is the principal vector of Lyme disease on the East Coast and in the upper Midwest regions of the United States, yet the tick is also present in the Southeast, where Lyme disease is absent or rare. A closely related species, I. affinis, also carries the pathogen in the South but does not seem to transmit it to humans. In order to better understand the geographic diversity of t...
