Following experimental inoculation of 3-week-old turkeys with different titres (106, 104, 103, 102 and 101 egg infectious dose (EID50)) of A/ostrich/Italy/984/2000 H7N1 highly pathogenic avian influenza virus (HPAIV), the selected tissues and organs were examined for pathological changes. Tissue samples from different organs that obtained from dead and sacrificed birds were fixed in 10% neutral...
Pathogenicity and virulence of entomogenous fungus, Verticillium lecanii, was studied on the pea aphid, Acyrthosiphon pisum. Vertalec, a commercial product of V. lecanii, was evaluated under controlled conditions. Second instar nymphs were inoculated with conidial suspensions at concentrations ranging from 104 to 108 conidia/ml, and sterile distilled water (containing wetting agent) as control,...
This study investigated seasonal changes in density and diversity of phytoplankton, chlorophyll a content, and some environmental characteristics in the Sistan region during 2014. Totally, we detected 28 genera that belonged to five groups of Chlorophyta (12 genera), Bacilloriophyta (7 genera), Cyanophyta (5 genera), Dinophyta (3 genera), and Euglenophyta (1 genus). We observed that Chlorophyta...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

چکیده تمام نما مقدمه: این تحقیق برای بررسی میزان خلاقیت و عناصر آن (انعطاف- سیالی- ابتکار و بسط) در کارشناسان فوق برنامه های تربیت بدنی دانشگاههای تهران صورت گرفته است. بطور کلی خلاقیت به معنای توانایی تولید اندیشه ها و ایده های جدید و ترکیب آنها با یکدیگر و بیشتر در جنبه های فکری نظری و به اصطلاح فعالیتهای ذهنی و طراحی قبل از عمل به کار می رود و دارای چهار عنصر به شرح زیر می باشد. 1- سیالی...
Kinesin-3 motor UNC-104/KIF1A is essential for transporting synaptic precursors to synapses. Although the mechanism of cargo binding is well understood, little is known how motor activity is regulated. We mapped functional interaction domains between SYD-2 and UNC-104 by using yeast 2-hybrid and pull-down assays and by using FRET/fluorescence lifetime imaging microscopy to image the binding of ...
The human cytotoxic T-cell line TALL-104 displays antitumor effects in animals with implanted and spontaneous malignancies. A Phase I trial was conducted to determine toxicity of TALL-104 cell therapy in women with metastatic refractory breast cancer. Fifteen patients with metastatic infiltrating ductal (n = 12), lobular (n = 2), or medullary (n = 1) carcinoma received escalating doses of letha...
