We aimed to examine the effect of micronutrient losses through sweat on blood pressure (BP) among heat-exposed steelworkers. A total of 224 heat-exposed male steelworkers from an ironworks facility were evaluated in July 2012. We measured the Wet Bulb Globe Temperature Index to evaluate the level of heat stress in the workplace. We collected sweat from the workers during an eight-hour work, and...

In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...

in this study for determinination of effects of anesthesia with propofol on some of biochemical factors of blood, 120 grass carp were chosen. the fish were exposed to the ascending concentration of propofol by bath method and injection method. at the time of anesthesia and 4 days after anesthesia blood samples were taken from the caudal vein and some biochemical parameters of blood were measure...

in order to evaluate effects of water stress and foliar application humic acid on quantities and qualitative in borage, a field experiment was conducted as a split plots design with three replication in 2012 at agricultural research station, university of zabol. water stress treatments included control or 90 percent of field capacity (w1), 70 percent field capacity (w2) and 50 percent field cap...

Potassium channel function is fundamental to many physiological processes in plants. In this issue of Cell, identify a protein complex in Arabidopsis consisting of a potassium channel, a protein kinase, and a calcium sensor. This study reveals that plants cope with limited soil potassium by coupling potassium channel activation to a cellular calcium signaling network.

The convenience and accuracy of flame photometric determinations of sodium and potassium in biological fluids (1, 2) have suggested the desirability of extending these advantages to determinations of calcium. Since calcium emission lines are much less intense than those of sodium and potassium (3), the samples of diluted serum (1: 50) customarily used for sodium and potassium determinat.ions ar...

Abstract Background Blood transfusion is associated with side effects caused by residual leukocytes in blood and blood components. Using leukodepleted blood components can decrease some of these adverse effects. Among the various methods to remove leukocytes in blood components, prestorage leukoreduction has been most efficient, but the evidence of clinical side effects awaits further studies...
