نیترات سازی یکی از فعال ترین فرآیندهای زیستی در خاک هایی است که کود نیتروژن آمونیومی دریافت کردهاند. سرعت این فرآیند تحت تأثیر غلظت آمونیوم، دما، رطوبت خاک، غلظت o2، ph، ec و اثرات متقابل این عوامل قرار دارد. در تحقیق حاضر تاثیر غلظت آمونیوم و رطوبت بر میزان نیترات سازی و نیز سینتیک این فرآیند در دو نمونه خاک a و b به ترتیب از دو منطق مرند و اهر مورد مطالعه قرار گرفت. در مرحله اول، آزمایشی به ...
Immunoglobulin G plays a vital role in adaptive immunity and antibody-based therapy through engagement of its Fc region by the Fc gamma receptors (Fc gammaRs) on immune cells. In addition to specific protein-protein contacts, N-linked glycosylation of the IgG Fc has been thought to be essential for the recognition of Fc by Fc gammaR. This requirement for the N-linked glycan has limited biomanuf...
Trittipyrum is an important annual grass plant for forage production in arid and semiarid regions. The effects of drought stress on Trittipyrum lines were evaluated in the field experiment in a randomized complete block design with a factorial experiment involving three replications in 2012. Treatments were water stress (field capacity (FC), 75% of FC, 50% of FC and 25% of FC throughout the exp...
به منظور بررسی اثرات تنش کم‌آبی و کود نانو پتاسیم بر برخی خصوصیات رویشی و فیزیولوژیکی نعنافلفلی، تحقیقی در سال 1393 در شرایط گلخانه به‌صورت فاکتوریل در قالب طرح بلوک کامل تصادفی با سه تکرار انجام شد. سطوح مختلف کم آبی شامل سه سطح (آبیاری کامل(100%FC)،۸۰ درصد ظرفیت مزرعه (80%FC) و۶۰ درصد ظرفیت مزرعه ای(60%FC) و محلول‌پاشی نانوپتاسیم در چهار سطح( (عدم محلول پاشی(T1)، محلول پاشی(T2: 2 در هزار)، (...
Fc gamma receptors (Fc gammaRs) bind the constant Fc region of IgG molecules. IgG/antigen-containing immune complexes elicit a variety of effector functions in cells that express activating Fc gammaRs. Because activating Fc gammaRs are present on cells from the innate immune system, such as dendritic cells, monocytes/macrophages and granulocytes, these IgG receptors form a crucial link between ...
Parkinson's disease is characterized by progressive degeneration of dopaminergic neurons. Thus the development of therapeutic neuroprotection and neurorescue strategies to mitigate disease progression is important. In this study we evaluated the neuroprotective/rescue effects of erythropoietin Fc fusion protein (EPO-Fc) and carbamylated erythropoietin Fc fusion protein (CEPO-Fc) in a rat model ...
water deficit and low nitrogen content of soil are the two major yield limiting factors in most maize (zea mays l.) producing areas. the objective of the current research was to evaluate the relationships between photosynthetic water and nitrogen use efficiency at different levels of soil moisture and nitrogen contents. a factorial experiment, based on completely randomized design with 3 replic...
The Fc-region of immunoglobulin E (IgE) comprising C epsilon 2, C epsilon 3, and C epsilon 4 domains is sufficient for binding to the alpha chain of the high affinity IgE-Fc receptor (Fc epsilon RI alpha). In order to identify the smallest Fc fragment capable of binding to the Fc epsilon RI alpha with high affinity, various regions of the IgE-Fc molecule were expressed in COS cells and investig...
1,1’-Diaminoferrocene (1) was converted to α-aminonitriles fc[NHC(CN)MeR’]2 (fc=1,1’-ferrocenediyl; 2 a: R’=Me, b: R’=Ph, c: R’=tBu) by reaction with ketones MeC(O)R’ in the presence of NaCN/HOAc or diimine fc(N=CPh2)2 (3) condensation Ph2CO. Treatment a–c 3 MeLi furnished fc(NHR)2 (4 R=tBu, 4 R=CMe2Ph, R=CMe2tBu, d: R=CMePh2) after aqueous work-up. The formylative cyclisation a–d fc[(NR)2CH][B...
