Abstract:

Mantenir la homeòstasis de cations és essencial per la supervivència dels éssers vius, i en especial pels organismes unicel·lulars. El llevat Saccharomyces cerevisiae s’ha utilitzat al llarg dels anys com un organisme model per l’estudi del conjunt de processos que controlen els nivells intracel·lulars de cations. El potassi és el principal catió intracel·lular del llevat i està involucrat en diversos processos de la fisiologia d'aquest organisme. Per aquest motiu la seva homeòstasis està minuciosament controlada per un seguit de transportadors que permeten la seva captació, distribució intrac

This study uses the structural coordinates of the determined K+ channels to create comparative models of three diverse members of this family, with the aim of enabling a better understanding of the function of these channels. The K+ channel of primary interest is the hERG K+ channel. The pharmacology of this channel is of considerable interest as serendipitous block of K+ conduction pore may result in cardiac arrest. A set of known antagonists have been docked into novel comparative models of hERG to propose how these drugs interact with the channel. The models have also been subjected to mole

Abstract:

The pancreatic ATP-sensitive potassium (KATP) channels couple glucose metabolism to excitability of the pancreatic β-cells to regulate insulin secretion. The channel subunits, Kir6.2 and SUR1, are encoded by the KCNJ11 and ABCC8 genes respectively. Genetic polymorphisms in these genes, which reduce channel activity, cause congenital hyperinsulinism (CHI) characterized by insulin hyper-secretion and hypoglycemia. The hERG (human ether-a-go-go related gene) potassium channels,encoded by the KCNH2 gene, contribute to the rapidly activating delayed rectifier K+ current (IKr), which is responsible

Abstract:

Limbic encephalitis (LE) is a central nervous system disorder that is characterised by memory impairments, confusion, agitation and seizures, and associated with hyperintense lesions of the medial temporal lobe, seen with MRI. Anti-voltage-gated potassium channel (VOKC) antibodies have been been detected in the plasma of a subset of LE patients using a 125I-a-dendrotoxin (a-DTX) radioimmunoprecipitation assay, suggesting that the likely antigens are VOKC Kv1.l, 1.2 and 1.6 subunits.

Abstract:

Effects of potassium supplementation were evaluated in four studies in endurance horses during races and treadmill exercise. In the first and second studies a potassium-free experimental formula was compared to potassium rich commercial formulas. The first study showed that supplementation increased plasma [K+], and that the extra sodium in the potassium-free experimental formulas helped to attenuate acidosis at the end of the ride. In the second study supplementation also increased plasma [K+], however speeds were lower and no increases were observed in plasma concentrations during the rac

Under stress, Chlamydiae can enter a persistent state, in which aberrant bodies (ABs) with reduced metabolic activity are formed. Surprisingly little

Abstract:

NKN doped samples, (100-x)NKN-xSBN (0 ≤ x ≤ 10) were produced using the conventional mixed oxide route with 0.45 wt% Fe2O3 sintering aid (xSBNF). After 20-24 hours mixing, samples were calcined at 850°C and sintered at 1100–1140°C (± 180°C/hour) for 4 hours. By XRD 4 mol% SBN was found to be the solubility limit for single phase structure. By SEM, second phases were visible when 2 ≤ x ≤ 4; their structure was subsequently shown to be tungsten bronze type (TBT). 2-4 SBNF samples were high density, over 96% theoretical. For x = 0, TC = 457°C, TO-T = 234°C, Pr = 22 μC/cm2 and EC = 16.5 kV/cm. TC

Abstract:

Background: Kv2.1 and TASK-1 channels are two main contributors of K+ currents in pulmonary artery smooth muscle cells (PASMC). Dysregulation of these channels has been implicated in the pathogenesis of pulmonary hypertension (PH). This thesis aims to delve deeper into the implications of the regulation of Kv2.1 by Kv9.3 in PH. Another subject of interest would be whether NADPH oxidase type 4 (Nox4), one of the major reactive oxygen species (ROS) producers in the PASMC, modulates Kv2.1, Kv9.3, and TASK-1 channels.

However, potassium is an essential plant macronutrient and we are seeing worldwide imbalances in nutrient and fertilizer use, as well as a need for a slow release potassium fertilizer.

The processing of sensory signals is an important, yet complex task in which a system must extract behaviorally relevant stimulus patterns from a vast array of sensory cues. When a neuron within a major sensory area is presented with a stimulus, one of the important characteristics used to distinguish between types of input is frequency. Often sensory neurons are tuned to narrow stimulus frequency ranges and are thus charged with the processing of subtypes of sensory signals.
