برای تعیین شاخصهای انحراف از درصد بهینه (DOP) و روش تلفیقی تشخیص و توصیه (DRIS) ارزیابی وضعیت تغذیهای پیاز (Allium cepa L.) و مقایسه دو روش مذکور، نمونههای برگ از 50 مزرعه جمعآوری و غلظتهای عناصر غذایی N، P،K ، Ca،Mg ،Fe ،Mn ، Zn ،Cu و B تعیین شدند. با توجه به مقدار عملکرد، مزارع به دو گروه، مزارع با عملکرد بالا و پایین تقسیم شدند. نرمهای DRIS برای نسبتهای مختلف عناصر غذایی تعیین شدند. ...
Drought stress is one of the most important environmental stresses in reduce of growth and plants production. Determination of resistance mechanisms to environmental stress in plant improvement is very important. In order to , experiment with osmotic potentials of PEG (zero (control), -4, -8 & -12 bar) and alfalfa genotypes was done. The selected alfalfa genotypes namely, Yazdi(tolerant), Niksh...
To maintain Ca(2+) entry during T lymphocyte activation, a balancing efflux of cations is necessary. Using three approaches, we demonstrate that this cation efflux is mediated by Ca(2+)-activated K(+) (K(Ca)) channels, hSKCa2 in the human leukemic T cell line Jurkat and hIKCa1 in mitogen-activated human T cells. First, several recently developed, selective and potent pharmacological inhibitors ...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
Angiotensin II Relaxes Microvessels Via the AT 2 Receptor and Ca 2+ -Activated K + (BK Ca ) Channels
Large-conductance Ca(2+)-activated K(+) (BK(Ca)) channel encoded by K(Ca)1.1 plays an important role in the control of smooth muscle tone by modulating membrane potential and intracellular Ca(2+) mobilization. BK(Ca) channel is functionally expressed in prostatic smooth muscle cells, and is activated by α(1)-adrenoceptor agonists. The main objective of this study was to elucidate the pathophysi...
