تعیین اندازه واحد دامی و نیاز روزانه گوسفند نژاد فشندی چرا کننده در مرتع (مطالعه موردی منطقه طالقان)
Information on animal requirements for determination of rangeland grazing capacity is essential. Animal requirements depend on its live weight, age, physiological condition and quality of available forage. There are more than 20 sheep breeds with different body sizes grazing in various climatic zone's rangelands of Iran, so animal unit equivalent of each breed should be determined independently...
The International Rice Research Institute (IRRI) has published the Rice Bibliography (RB) since 1963. IRRI had the Japan Library Office, which compiled the 1990-2000 Bibliography of Japanese Rice Research (BJRR) with the aims to provide more efficient information retrieval and bibliometrics in a specific-subject bibliographic database. We investigated the characteristics of Japanese rice resear...
BACKGROUND This study aimed to investigate the possible serum protein changes after endotoxin administration in healthy and choline-treated calves using proteomics. These results are expected to contribute to the understanding of the pathophysiological mechanisms of endotoxemia and the beneficial effect of choline administration in this clinical situation. METHODS Healthy-calves (n = 20) were...
Maf family proteins are so named because of their structural similarity to the founding member, the oncoprotein v-Maf. The small Maf proteins (MafF, MafG and MafK), as do all family members, include a characteristic basic region linked to a leucine zipper (b-Zip) domain which mediate DNA binding and subunit dimerization respectively. The small Maf proteins form homodimers or heterodimers with o...
A conventional baker’s yeast strain D incorporated trehalose into its cells from a YPG medium supplemented with trehalose. Cells cultured in a medium containing 3 to 5% trehalose increased to nearly 5 times the trehalose content of cells cultured in the absence of trehalose. After 1 day of frozen storage at -2O”C, cells cultured in 3% trehalose medium experienced a lesser decrease in both viabi...
این تحقیق به منظور بررسی غلظت فلزات سنگین روی، مس، کادمیوم و آهن در بافت پوست، عضله، آبشش و گناد شگ ماهی (alosa braschnikowi) در نواحی جنوبی دریای خزر(بابلسر) در سال 1393 به اجرا در آمد. بدین منظور 70 قطعه نمونه ماهی در دو فصل پاییز و زمستان به صورت تصادفی از پره های صید تهیه و مورد زیست سنجی قرار گرفتند. پس از هضم نمونه ها، غلظت فلزات توسط دستگاه جذب اتمی شعله اندازه گیری شد. نتایج نشان داد، ک...
Levels of contaminants in fish are of particular interest because of the potential risk to humans consuming them. This paper examines the levels of cadmium, lead, zinc and copper in liver and muscle tissue of Esox lucius and in sediments from the Anzali international wetland in Iran. The wetland is a nursery and feeding habitat for fish species both from the lagoon and the Caspian Sea, which ar...
Desalination plants are potentially capable of having impacts on coastal marine environments due to the production of wastewater with high concentrations of salts (brine discharge) and some heavy metals. The aim of this study was to examine the concentration of accumulated metals (Ni, Cu, Cd, Fe, Zn, Pb) in the sediments near the brine discharge point in the Chabahar Bay. Twenty one sediment sa...
In this study, arsenic concentration and hazard quotient (HQ) in eight species of marine fish in Khuzestan province including Epinephelus coioides, Acanthopagrus latus, Platycephalus indicus, Cynoglossus arel, Pampus argenteus, Tenualosa ilisha, Liza macrolepis and Liza klunzingeri were studied. This research was conducted in 2020. 15 fish were prepared from any of the different or fish landing...
در این مطالعه غلظت فلزات سنگین کادمیوم ،سرب ،جیوه و آهن در بافت عضله18 نمونه ماهی شوریده(Otolithes ruber) ، تهیه شده از صیدگاه بندر عباس در زمستان 88 و تابستان 89 به منظور مقایسه حد مجاز آنها با استاندارد های جهانی اندازه گیری شد.پس از آماده سازی نمونه ها و هضم آنها به روش (AOAC) غلظت فلزات کادمیوم ،سرب ،جیوه و آهن توسط دستگاه جذب اتمی مدل 220Z اندازه گیری شد . میانگین وزن ماهیان مورد مطالعه ب...
