Two-pore-domain (K(2P)) potassium channels mediate background potassium currents, stabilizing resting membrane potential and expediting action potential repolarization. In the heart, K(2P)3.1 (TASK-1) channels are implicated in the cardiac plateau current, I ( KP ). Class III antiarrhythmic drugs...
Read the following passage and then do the exercises (multiple choice) given below.PRINCIPLES OF PHARMACODYNAMICSOnce a drug accesses a molecular site of action, it alters the function of that molecular target, with the ultimate result of a drug effect that the patient or physician can perceive....
The small conductance calcium-activated potassium channel 3 (SK3) is a molecular target for Edelfosine to reduce the invasive potential of urothelial carcinoma cells. Tumour Biol. 2016;37: 6275-83.
What is the molality of ions in a 0.450 M aqueous solution of potassium phosphate? What is the molar mass, in grams, of a mole of an element equal to? What is the mass of 2.21 mol of Na2S? What is the molar mass of ammonia?
). DE analysis revealed no significant differences between DMSO (vehicle) and potassium simplex optimized medium (KSOM) (control) embryos, so we performed all subsequent analyses against the DMSO group. Embryos grown with LY2955303 displayed a transcriptional program that differed from controls (...
Diabetic patients receiving the antidiabetic drug metformin have been observed to exhibit a lower prevalence of anxiety disorders, yet the precise mechanism behind this phenomenon is unclear. In our study, we found that anxiety induces a region-specific reduction in AMPK activity in the medial prefro...
Zinc (Zn) is an essential trace element in living organisms and plays a vital role in the regulation of both microbial virulence and host immune responses. A growing number of studies have shown that zinc deficiency or the internal Zn concentration does not meet the needs of animals and microb...

The mineralocorticoid receptor (MR) in mammals mediates the effects of aldosterone in regulating fluid balance and potassium homeostasis. While MR signalling is essential for survival in mammals, there is no evidence that MR has any physiological role in ray-finned fish. Teleosts lack aldosterone and...
Electrolytes (sodium, potassium, calcium) were determined by flame photometric assays using a flame photometer EFUX 5057 (Eppendorf-Netheler-Hinz GmbH). Chloride was estimated by coulometric analysis on a Chloridmeter 50 (Kreienbaum Wissenschaftliche Meßsysteme e.K.). The study was performed ...
