To identify genes involved in cardiac arrhythmia, we investigated patients with long QT syndrome (LQT), an inherited disorder causing sudden death from a ventricular tachyarrythmia, torsade de pointes. We previously mapped LQT loci on chromosomes 11 (LQT1), 7 (LQT2), and 3 (LQT3). Here, linkage and physical mapping place LQT2 and a putative potassium channel gene, HERG, on chromosome 7q35-36. S...
Background: Coffee contains thousands of chemical compounds such as chlorogenic acid, caffeine, potassium, niacin, magnesium and tocopherols. Only caffeine in coffee shows pharmacological effects. Based on relevant studies, caffeine in coffee has many side effects such as increasing blood pressure, homocysteine, plasma renin; catecholamine and arrhythmia, which are considered as risk factors fo...
BACKGROUND Changes in brain derived neurotrophic factor (BDNF) expression have been associated with mood disorders and cognitive dysfunction. Transgenic models that overexpress or underexpress BDNF demonstrate similar deficits in cognition and mood. We explored the hypothesis that BDNF expression is controlled by balancing the activity of BDNF promoter IV (BP4) with a negative regulatory region...
Salinity stress is one of the most widespread soil problems next to drought, in rice growing areas. ReducingSodium (Na+), while maintaining Potassium (K+) uptake in rice are traits that would aid in salinity tolerance.Therefore, the identification of quantitative trait loci (QTLs) associated with those for Na+ and K+uptake, will enable breeders to use marker-assisted selection...
the present research designed to evaluate the effects of foliar application of methyl jasmonate (meja), salicylic acid (sa) and potassium sulfate on improving fruit quality and photosynthesis system. ten treatments include: sa (0.3, 0.6 and 0.9 mm), meja (0.5, 1 and 2 mm), potassium sulfate (0.5, 1 and 1.5%) and distilled water (control) were sprayed on pomegranate trees 2 and 7 weeks after ful...
The objective of this study was determining the most limiting plant growth factor in the wheat root zone dominated by illite in clay fraction and a high specific surface with ample ammonium acetate extractible potassium. A completely randomized block design with 4 replicates was used in Seyed Miran Research Farm (Gorgan) during 2009-2010 growing season. Treatments were mineral fertilizers (to a...
In the present study, response of Pistachio (Pistacia vera L.) on nitrate reductase activity, some biochemical characters and ions accumulation to salinity were evaluated. Salinity treatments (0, 75, 150 mM NaCl) and potassium nitrate (0, 10, 15 mM) were imposed and sampling were done 100 days after treatments. Results indicated that sodium chloride at 75 mM plus 10 mM potassium nitrate resulte...
background in contemporary practice, acute mesenteric ischemia (ami) remains a serious cause of morbidity and mortality in abdominal emergencies. objectives we report the measurement of peritoneal fluid potassium and ph on a small series of rats that developed extensive ami following the surgical ligation of superior mesenteric vessels and compare the results with control groups. materials and ...
for investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the research field of islamic azad university, jiroft, iran in 2013-2014. the main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of crop ...
