The polymorphism of liquid cesium at atmospheric pressure in thetemperature range ~590 K the form a second-order phasetransition, announced late 90s, is not confirmed new experimentalworks and computer simulations its properties. At same time, thequestion whether change properties with adecrease or increase density up to two times monotonous isaccompanied by various anomalies needs further rese...

This article shows the results of studies in course which a comparative aspect LEP polymorphism was studied subpopulations Holstein dairy cattle cows with fatty hepatosis and healthy animals. is first time such are being conducted. In this case, hepothesis about relationship genetic markers, particular leptin gene, risk developing progression liver disease model when determining frequency occur...

Under physiological conditions, potassium channels are extraordinarily selective for potassium over other ions. However, in the absence of potassium, certain potassium channels can conduct sodium. Sodium flux is blocked by the addition of low concentrations of potassium. Potassium affinity, and therefore the ability to block sodium current, varies among potassium channel subtypes (Korn, S.J., a...

In eusocial insects, worker polymorphism is shaped by several factors, including colony size, queen mating frequency, and the timing of queen-worker differentiation during larval development. a comparative study 18 species Cataglyphis desert ants representing wide range sizes, we used phylogenetically controlled analyses to examine correlations between head width variation (i.e., polymorphism) ...

INTRODUCTION Electrolyte abnormalities are one of the common causes of morbidity and mortality in critically ill patients. The turnaround time for electrolyte reporting should be as low as possible. Electrolytes are measured conventionally in serum obtained from venous blood by electrolyte analyser which takes 20 to 30 min. Point of care analysers are now available where in electrolytes can be ...

The intracellular potassium content of perfused rat heart was measured by potassium-39 nuclear magnetic resonance (NMR) spectroscopy at 33 degrees C with an inversion recovery technique based on the fact that the spin-lattice relaxation time (T1) of the intracellular potassium (8.3 msec at 8.45 T) is much faster than that of the extracellular potassium (68 msec). Intracellular potassium decreas...

We examined the independent effects of a high potassium diet and increased aldosterone levels on the development of renal potassium adaptation. This condition is defined by the increased ability of the kidneys to excrete an acute infusion of potassium. Rats were adrenalectomized (ADX) and received aldosterone at basal levels (0.5 microgram/100 g X d) or at high levels (2.0 micrograms/100 g X d)...

Hypokalemia is frequently encountered in clinical practice. It can be due to either potassium deficiency (inadequate potassium intake or excessive potassium loss) or to net potassium shifts from the extracellular to the intracellular compartment. Inadequate dietary intake of potassium alone rarely causes hypokalemia since kidney is able to lower potassium excretion below 15 mmol per day. Hypoka...
