abstract the whole blood potassium concentration has shown the bimodal distribution in sheep, which has been classified into lk and hk types; hk allele is recessive to lk with a single gene inheritance. this polymorphism showed different behavior in different environment, which could be due to adaptation process. this research was conducted on the zel and kermani breed research station, which k...
statins have antioxidant and anti-inflammatory effects that are not directly related to their cholesterol-lowering activity. this study aimed to investigate the effect of simvastatin on the extent of tissue damage in cisplatin-induced nephrotoxicity. simvastatin was orally given to rats in different doses (1, 2 and 4 mg/kg), 1 h prior to cisplatin injection (5 mg/kg, i.p.). all animals were dec...
Alterations in red blood cell (RBC) Na+,K+ pump and in Na+,K+ cotransport (CoT) have been described in essential hypertension (EH). We examined pump and CoT in 50 normotensive (NT) subjects and 58 EH subjects subdivided by race and family history of hypertension (+ FH). RBCs were preloaded with Na+ to obtain intracellular levels of 25 mM/liter cells by using the p-chloromercuribenzene sulfonic ...
Hydroponically grown ten grape genotypes (Vitis vinifera L.) were treated with different concentrations of NaCl. Chawga genotype accumulated K+ in its root and shoot even at high salinity. The correlation between Na+ and K+ concentrations in root and lamina of all genotypes was negative (P
کلیه موش یک مدل مناسب برای تحقیق مربوط به ساختار و فیزیولوژی کلیه پستانداران از جمله انسان است. در بین حیوانات آزمایشگاهی، موش Nude به عنوان مدل در مطالعات مربوط به سرطان استفاده می‌گردد. یه دلیل اهمیت رابطه بین پمپ سدیم و پتاسیم و سرطان، ساختار نفرون و مکان‌یابی آنزیم Na+, K+-ATPase در بخش‌های مختلف کلیه موش Nude مورد بررسی قرار گرفت. شش سر موش Nude از انستیتو پاستور (شعبه آمل) تهیه و کلیه آنه...
Geochemical Aspects of Na-Metasomatism in Sargaz Granitic Intrusion (South of Kerman Province, Iran)
The Sargaz granitic intrusion has been emplaced in Sargaz ophiolitic suite, south-east of Sanandaj-Sirjan metamorphic zone, south of Kerman province. The central part of the intrusive body contains pinkish coarse-grained granite, but the fractured northern part, neighboring Chah-Mazraeh fault, has been subjected to pervasive Na-metasomatism and related subsolidus reactions. In the northern alte...
This paper is the third in a series of reviews published in this issue resulting from the University of California Davis Cardiovascular Symposium 2014: Systems approach to understanding cardiac excitation-contraction coupling and arrhythmias: Na(+) channel and Na(+) transport. The goal of the symposium was to bring together experts in the field to discuss points of consensus and controversy on ...
To examine the response of three rapeseed varieties to salinity stress, a pot experiment was conducted in a glasshouse using a factorial experiment based on a randomized complete block design with three replications. Three levels of NaCl (0, 100 and 200 mM NaCl) were imposed as the salinity treatments at root establishment (leaf 4) stage. In this study, sodium (Na+) and potassium (K+) concentra...
Contents of inorganic elements are very important traits in plants. Some of elements have causal effects on plant growth. Their effects on plant metabolism and therefore quality and quantity of essential oils is crucial. Thus, to obtain relatively good results, different parts of Rosa damascena Mill. genotypes were analyzed. Plants were collected from different provinces including Tehran, East ...
To increase our understanding of the physical nature of the Na+ and K+ forms of the Na+ + K+-dependent ATPase, thermal-denaturation studies were conducted in different types of ionic media. Thermal-denaturation measurements were performed by measuring the regeneration of ATPase activity after slow pulse exposure to elevated temperatures. Two types of experiments were performed. First, the depen...
