this study was carried out to evaluate the changes in some important cell parameters under water limitation in sorghum genotypes. a factorial experiment was conducted based on randomized completely design in greenhouse, in university of mohaghegh ardabili in 2014. treatments were water stress at levels of 85, 65, 45 and 25 percent field capacity in and three genotypes of forage sorghum (kfs2, k...

This report further examines the relation of body mass index (BMI) to associations of 24-hour urinary sodium, potassium, and sodium-potassium ratio with blood pressure in INTERSALT, a 52-center international study of electrolytes and blood pressure. Analyses without adjustment for BMI indicated average systolic pressure greater by 6.00 mm Hg per 100 mmol higher sodium and diastolic by 2.52 mm H...

Salinity is one of the greatest environmental challenges facing plant growth and development in the 21st century. Salicylic acid (SA) is a phenolic compound and signal molecule involved in the regulation of plants responses to biotic and abiotic stresses. This greenhouse experiment was conducted to determine effects of SA application on Kentucky bluegrass (Poa pratensis L.) responses to salinit...

1. Blood pressure, height, weight and 24 h urinary output of sodium, potassium and creatinine were measured in over 500 adults of each sex during a health survey of the population of a small town. 2. Both systolic and diastolic pressure were significantly related to Quetelet's index (weight/height2) and heart rate. 3. There was no significant relationship between blood pressure and output of so...

backgrounds and aims: the purpose of this study was to examine the effects of potassium, sodium and zinc metal ions on ammonium sulfate fraction of acid phosphatase activity of orange fruit. materials and methods: acid phosphatase was extracted and purified from orange fruit and then various samples as well as a control sample were prepared in vitro. in addition to substrates, ions of potassium...
