Introduction Chronic kidney disease (CKD) is associated with high cardiovascular morbidity and mortality. Recent evidence suggests that increases in both serum and intracellular magnesium (Mg) can slow or even prevent the development of vascular calcification seen in CKD. Serum calcification propensity (T50) is a novel functional test, which is associated with all-cause mortality in CKD and mea...

Hypercholesterolemia and atherosclerosis have been associated with changes in the microvasculature, in particular with endothelial dysfunction. In the present study, the impact of atherogenic conditions on arteriolar vasomotor control was determined. Arteriolar [second-order (2A) and third-order (3A) arterioles; diameter range: 9-37 microm] responses during reactive hyperemia (RH) were determin...

PURPOSE Firstly, to assess the effect of percutaneous endoscopic gastrostomy (PEG) tube placement on gastric emptying, gastrointestinal (GI) tract motility and the rate of gastroesophageal reflux (GER). Secondly, to confirm whether correlations exist between drug absorption behaviour and GI tract motility using the combination method of absorption function analysis with the motility study. ME...

OBJECTIVE To evaluate the correlation between the half-time of liquid-phase gastric emptying (T50) determined by use of nuclear scintigraphy, using technetiumTc 99m pentetate, and absorption variables of orally administered acetaminophen in horses with experimentally delayed gastric emptying. ANIMALS 6 mature horses. PROCEDURE Delayed gastric emptying was induced by IV injection of atropine...

BACKGROUND AND OBJECTIVES Minimum T50 and T95 onsets are the medians of time intervals between end of skin and subcutaneous tissue infiltration with local anesthetics and a painful stimulation, which are associated to no pain in 50% and 95% of patients, respectively. This study has evaluated T50 and T95 of subcutaneous 1% lidocaine for lumbar skin puncture. METHODS This was a prospective stud...

in order to assess the genetic variability for seed germination parameters under salt stress in sunflower and corresponding qtl locations, an experiment was conducted using a population of 80 recombinant inbred lines obtained from a cross between pac2 and rha266. the experiment was arranged under a randomized complete block design with three replications in control and saline conditions. severa...

OBJECTIVE/BACKGROUND To evaluate whether the outcome of radiofrequency ablation (RFA) treatment of great saphenous vein (GSV) incompetence may be predicted using strain-gauge plethysmography (SGP) with selective occlusion of the superficial venous system. METHODS Seventeen patients (20 limbs) underwent endovenous RFA treatment for GSV incompetence (Clinical Etiology Anatomy Pathophysiology cl...

BACKGROUND Endothelin-1 (ET-1) is released after hyperkalemic cardioplegic arrest (CA) and reperfusion and may contribute to contractile dysfunction. ET-1 receptor transduction causes activation of protein kinase C (PKC) isoforms, which can cause differential intracellular events. The goal of this study was to determine which PKC isoforms contribute to myocyte contractile dysfunction with ET-1 ...
