OBJECTIVE
Oxidative damage has been implicated in the pathogenesis of cerebral ischemia. We previously demonstrated that exogenously supplied dehydroascorbic acid (DHA), an oxidized, blood-brain barrier transportable form of the antioxidant ascorbic acid (AA), improves outcome after experimental
Corafusin, an infusion solution containing lidocaine, electrolytes and sorbitol, was tested during 4-day continuous infusion of patients with myocardial infarction. The serum sodium level remained constant within the normal range whereas initially reduced serum potassium and magnesium concentration
Insulin-like growth factor-1 (IGF-1) isoforms are expressed via alternative splicing. Expression of the minor isoform IGF-1Eb [also known as mechano-growth factor (MGF)] is responsive to cell stress. Since IGF-1 isoforms differ in their E-domain regions, we are interested in determining the
Brain edema was induced in primates (Macaca mulatta) after regional cerebral ischemia produced by selective embolization of the internal carotid artery bifurcation. Details of the alterations in the distribution of water and electrolytes in the brain during the evolution of ischemic cerebral edema
BACKGROUND
Diabetes mellitus is an independent risk factor for cardiovascular disease and is also associated with increased susceptibility to cardiovascular complications. It has been suggested that alterations in glucose metabolism and glucose flux via the aldose reductase pathway make the diabetic
A complex of enzymatic tests, characterizing the liver function and cellular cytolysis in patients with acute myocardial infarction of various severities (without complications and with various types of complications and outcomes) was used in examinations over the first week of the disease.
The volume of distribution of [60Co]EDTA in normal dog myocardium is slightly less than that calculated from tissue contents of H2O, Cl, K, and their extracellular fluid (ECF) concentrations subsuming a steady state across cell membranes. The volume of distribution of [3H-]sorbitol was substantially
In recent years the number of patients with partial or total rectal prolapse has increased. Numerous techniques and surgical approaches have been described for its treatment. In this study we examine the main ones and stress the advantages of the transanal-perineal resection technique according to
Acute stroke presents an emergency that requires immediate referral to a specialized hospital, preferably with a stroke unit. Disability and mortality are reduced by 30% in patients treated in stroke units compared to those treated on regular wards, even if a specialized team is present on the ward.
Aldose reductase (AR) catalyzes the reduction of several aldehydes ranging from lipid peroxidation products to glucose. The activity of AR is increased in the ischemic heart due to oxidation of its cysteine residues, but the underlying mechanisms remain unclear. To examine signaling mechanisms
Diabetes mellitus is one of the diseases with the greatest risk of developing coronary disease (CD), with the estimation of this risk in relation to the general population being from 2 to 4-fold greater. The existence of diabetes worsens the prognosis of CD and thus, postinfarction mortality in
Aging men and women display both increased incidence of cardiovascular disease and complications of myocardial infarction and heart failure. We hypothesized that altered glucose metabolism, in particular, flux of glucose via the polyol pathway (PP) may be responsible, in part, for the enhanced
A number of studies have shown that the polyol pathway, consisting of aldose reductase (AR) and sorbitol dehydrogenase (SDH), contributes to ischemia-reperfusion (I/R)-induced myocardial infarction due to depletion of ATP. In this report we show that the polyol pathway in I/R heart also contributes
Perfusion is thought to be impaired in brain edema due to reduced perfusion pressure. Brain edema therapy is assumed to improve perfusion. We assessed regional cerebral blood flow (rCBF), regional cerebral blood volume (rCBV) and mean transit time of blood (MTT) using perfusion-weighted magnetic
Hyperkalemia is a frequent electrolyte disturbance in patients on dialysis or non-dialysis CKD patients, including those using renin-angiotensin system inhibitor drugs. Sodium polystyrene sulfonate (SPS; Kayexalate) is a resin widely used for hyperkalemia treatment. Unfortunately, its use entails
