BACKGROUND T helper (Th) cells immune regulation is important for the pathogenesis of acute myeloid leukemia (AML). Recurrent Th abnormalities in AML peripheral blood were reported, while the comprehensive status of various Th subsets is rarely investigated in bone marrow (BM) microenvironment which is the origin of AML leukemic blast cells.

Although glial cell-line derived neurotrophic factor (GDNF) acts as a potent survival factor for dopaminergic neurons, it is not known whether GDNF can directly alter dopamine synthesis. Tyrosine hydroxylase (TH) is the rate-limiting enzyme for dopamine biosynthesis, and its activity is regulated by phosphorylation on three seryl residues: Ser-19, Ser-31, and Ser-40. Using a TH-expressing human...

در طی دو دهه گذشته، استفاده از نانو ذرات نقره در محصولات مصرفی افزایش چشم گیری داشته است، بنابراین انسان و موجودات زنده در معرض روزافزون آن قرارگرفته اند. فقدان دانش کافی در زمینه اثرات مواجهه ی پیش از تولد با نانو ذرات نقره، ما را بر آن داشت که به بررسی اثرات مواجهه پیش از تولد با این نانو ذرات، بر فعالیت حرکتی، تعادل، یادگیری حرکتی و بیان ژن های تیروزین هیدروکسیلاز (th) و مونو آمین اکسیداز a ...
Yersinia pestis, the etiologic agent of the disease plague, has been implicated in three historical pandemics. These include the third pandemic of the 19(th) and 20(th) centuries, during which plague was spread around the world, and the second pandemic of the 14(th)-17(th) centuries, which included the infamous epidemic known as the Black Death.

The objective of this study was to investigate the anthelmintic efficacy of drug (Butea monosperma) in Syphacia muris infected mice. The drugs were administrated to the infected mice on 18 , 19 and 20 post th th th infection days. The % efficacy due to test drug was observed on Larva and Adult worm recovery response. Larval and Adult worm recovery were found to be directly proportional to the d...
