The endothelium plays a key role in the control of vascular tone and alteration in endothelial cell function contributes to several cardiovascular disease states. Endothelium-dependent dilation is mediated by NO, prostacyclin, and an endothelium-derived hyperpolarizing factor (EDHF). EDHF signaling is thought to be initiated by activation of endothelial Ca(2+)-activated K(+) channels (K(Ca)), l...
In order to study the effect of zinc (Zn) nutrition on relative tolerance of olive (Olea europea L.) seedlings to salinity, a factorial pot experiment was conducted, based on completely randomized design with three replications, during fall 2013. One-year seedlings of two olive cultivars (‘Frontoio’ and ‘Conservolea’) were planted in 10-litre plastic pots containing sand and perlite (1:1 ratio)...
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 ...
background: electrolytes play an important role in the normal functioning of human body. electrolyte imbalance and mineral disturbances is the common clinical manifestation in several infectious diseases including malaria. malaria is a mosquito borne serious infectious disease of the world. plasmodium vivax and p. falciparum are the main agents responsible for malaria in pakistan. electrolyte i...
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...
برای بررسی اثر کشت مخلوط و کود دامی بر ترکیب شیمیایی، رشد و عملکرد ذرت (هیبرید سینگل کراس 704)، گاودانه و لوبیا چیتی (رقم تلاش) آزمایشی در سال زراعی 89-88 به صورت فاکتوریل و در قالب طرح بلوک های کامل تصادفی با سه تکرار در مزرعه ایستگاه تحقیقاتی خلعت پوشان دانشکده کشاورزی دانشگاه تبریز اجرا شد. فاکتورها شامل نوع کشت در 5 سطح (تک کشتی لوبیا چیتی، تک کشتی گاودانه، تک کشتی ذرت، کشت مخلوط ذرت با لوب...
embryonic stem cells are capable of differentiating to variety of cell tissues including cardiomyocytes. this developmental change is accompanied with a great deal of ion channel expression and functions. mouse stem cell derived cardiomyocytes were prepared and separated to yield isolated single cell suspension for cell current recording. in the present study some properties of the k + -current...
The adaptability of Haloxylon appilium to adverse environmental conditions and especially its capability for an appropriate establishment in saline and desert soils has introduced this plant as a suitable means for biological methods to stabilize sand dunes, control erosion and prevent desertification in arid regions. In order to evaluate the ecophysiological characteristics of Haloxylon appili...
Three strains of facultatively anaerobic thermotolerant and moderately halophilic bacteria were isolated from two Jordanian hot spring locations. The novel Bacillus strains were short rods, Gram-positive, motile and spore formers. The strains were capable of anaerobic (but not aerobic) growth at 63C, moderately halophilic, able to grow at NaCl concentration range of 12 15 % and at temperatures ...
