Let Fp = Z/pZ. The height of a point a = (a1, . . . , ad) ∈ F d p is hp(a) = min n Pd i=1(kai mod p) : k = 1, . . . , p − 1 o . Explicit formulas and estimates are obtained for the values of the height function in the case d = 2, and these results are applied to the problem of determining the minimum number of edges the must be deleted from a finite directed graph so that the resulting subgraph...

In cultured oligodendrocytes isolated from perinatal rat optic nerves, we have analyzed the expression of ionotropic glutamate receptor subunits as well as the effect of the activation of these receptors on oligodendrocyte viability. Reverse transcription-PCR, in combination with immunocytochemistry, demonstrated that most oligodendrocytes differentiated in vitro express the alpha-amino-3-hydro...

Background: The adenosine triphosphate (ATPhensitive potassium (KAm) channels protect myocytes during ischemia and reperfusion. This study investigated the effects of thiamylal on the activities of KATp channels in isolated rat ventricular myocytes during simulated ischemia. Methods: Male Wistar rats were anesthetized with ether. Single, quiescent ventricular myocytes were dispersed enzymatical...

We consider the strong rescattering effects that can occur in the decays such as B → Kπ, Kπ, Kρ . . . and their impact on direct CP violation in these modes. First we discuss, in general, how the CPT theorem constrains the resulting pattern of partial rate asymmetries leading to different brands of direct CP. Traditional discussions have centered around the absorptive part of the penguin graph ...

این پژوهش، مطالعه ی اثر سورفکتانت آنیونی سدیم دو دسیل سولفات (sds) بر روی تعادلات تفکیک اسید آمینه ی تریپتوفان است. تعادلات اسیدی– بازی تریپتوفان برحسب ثابت های تفکیک ماکروسکوپی، میکروسکوپی و نسبت های تاتومری در محلول آبی و در حضور غلظت های مختلف sdsبررسی شد. به این منظور مقادیر ثابت های ماکروسکوپی (ka1 وka2)، ثابت تاتومری kz و مقادیر ثابت های میکروسکوپی (k11، k12،k21 و k22 ) تعیین شدند و مورد ...

استفاده از رنگی که علاوه بر دارا بودن خصوصیات رنگی مشابه رنگهای مصنوعی ، دارای فوائد به اثبات رسیده در برخی از فراورده های غذایی نظیر روغن باشد، یک ضرورت است. از طرفی این رنگها می بایست فاقد مضرات رنگهای مصنوعی باشند. در این خصوص رنگ کانتاگزانتین بدلیل خاصیت رنگ دهی مشابه رنگ های مصنوعی و نداشتن مضرات آنها به عنوان یک رنگ کاملاً طبیعی برای استفاده در روغن های خوراکی ، گزینه مطلوبی به نظرمی رسد. ...

PURPOSE Light signals from rod and cone photoreceptors traverse distinct types of second-order, bipolar neurons that carry these signals from the outer to inner retina. Anatomic and physiologic studies suggest that the specialization of rod and cone bipolar cells involves the differential expression of proteins involved in glutamatergic signaling. In a previous study, we compared the expression...

CYP153, one of the most common medium-chain n-alkane hydroxylases belonging to the cytochrome P450 superfamily, is widely expressed in n-alkane-degrading bacteria. CYP153 is also thought to cooperate with AlkB in degrading various n-alkanes. However, the mechanisms regulating the expression of the protein remain largely unknown. In this paper, we studied CYP153 gene transcription regulation by ...

Bacterial wilt caused by Ralstonia solanacearum is one of the most destructive diseases which negatively affect the tomato production worldwide. Considering the importance of the disease, using biological control agents could be effective approaches in reducing the damage of the pathogen. Tomato samples of suspected bacterial wilt disease were gathered from different regions of East Azarbayjan....
