Oxalate oxidase (E.C. 1.2.3.4) catalyses the conversion of oxalate and dioxygen to carbon dioxide and hydrogen peroxide (for reviews see [ 1-31). Oxalate oxidase activity has been detected in a number of organisms but the best biochemically characterised enzymes are from barley and wheat. The plant enzyme is isolated as a glycosylated homopentamer which is remarkably resistant to heat, SDS and ...
This study investigates the effect of the aryloxypropanolamines 4-[3-[(1,1-dimethylethyl)amino]-2-hydroxypropoxy]-1,3-dihydro2H-benzimidazol-2-one (CGP 12177), bupranolol, and 3-(2ethylphenoxy)-1[(1S)-1,2,3,4-tetrahydronaphth-1-ylamino]-(2S)-2propanol oxalate (SR 59230A) [commonly used as 3and/or atypical -adrenergic receptors ( -AR) ligands] on the contractile function of rat intralobar pulmon...
مقدمه هورمونها از مهم ترین عوامل تنظیم کننده رشد گیاهان زراعی در پاسخ به اثرات محیطی و ژنتیکی محسوب میشوند. پاکلوبوترازول(pbz) یک تنظیم کننده رشد گیاهی از دسته تریازولها بوده و در اوایل دهه ۱۹۸۰ مورد استفاده قرارگرفت. اثرهای بیولوژیکی کاربرد پاکلوبوترازول در واقع ناشی از کاهش جیبرلین داخلی درگیاه است (fahimi, 2009). طبق نتایج برخی از پژوهشگران، پاکلوبوترازول باعث کاهش ارتفاع ساقه (yang et al...
Repeated administration of morphine is associated with the development of tolerance, yet the mechanism underlying this phenomenon is still poorly understood. Recent evidence implicating glycogen synthase kinase 3 (GSK3) in opioid receptor signaling pathways has prompted us to investigate its role in morphine tolerance. Administration of 10 mg/kg morphine i.p. to Wistar rats twice daily for 8 da...
GnRH is the primary stimulus in the regulation of gonadotropin subunit mRNA expression. Additionally, local (pituitary) production of activin and follistatin appear to modulate the expression of FSH b mRNA. The current studies aimed to determine whether GnRH regulation of pituitary activin (b-B) and follistatin mRNAs could play a role in the differential actions of GnRH pulse pattern on gonadot...
Cryoglobulinemia is characterized by a wide range of causes, symptoms, and outcomes. Hepatitis C virus (HCV) infection is detected in 30%Y100% of patients with cryoglobulins. Although more than half the patients with cryoglobulinemic vasculitis present a relatively benign clinical course, some may present with potentially lifethreatening situations. We conducted the current study to analyze the...
Invited Review: Reproducible and target-specific polymerase chain reaction (PCR) amplification relies on several interrelated factors of which primer design is central. Here, we describe new free bioinformatics software, the FastPCR which was developed, and continues to be updated, based on detailed experimental studies of PCR efficiency for the optimal design of primers and probe sequences and...
We wanted to determine which a-adrenoceptor subtypes mediate phenylephrine (PE) contraction of dog mesenteric artery in vitro. We studied antagonisms in response to prazosin, 2-(2,6-dimethoxyphenoxyethyl)-aminomethyl-1,4-benzodioxane, 5-methylurapidil, N-[2(2-cyclopropyl methoxy phenoxy)ethyl]5-chloro-a,a-dimethyl-1Hindole-3-ethanamine HCl (RS 17053), 8–3-[4-(2-methoxyphenyl)1-piperazinyl]propy...
