Value of troponin T as a screening test of cardiac structure and function in chronic kidney disease.

Background: Cardiovascular disease starts early in the course of chronic kidney disease (CKD) and is the leading cause of death in patients with end-stage renal disease. Since high-sensitivity cardiac troponin T (hs-cTnT) can detect much lower levels of myocardial injury than conventional assays, it may be useful for studying the earliest stages of heart disease in patients with CKD.

Objective: To evaluate the association of circulating hs-cTnT with LV structural and functional abnormalities detected by echocardiography among dialysis dependent and non-dialysis dependent CKD patients.

IL10 in Lupus Nephritis: Detection and relationship with disease activity.

Introduction: Glomerulonephritis is a major determinant of the course and prognosis of systemic lupus erythematosus (SLE) and is evident in 40%-85% of patients. IL10, a cytokine produced by monocytes and-to a lesser extent-lymphocytes, has pleiotropic effects in immune regulation and inflammation. It enhances B cell survival, proliferation, differentiation, and antibody production; these effects play a role in autoimmune diseases.

Novel troponin-like biomarkers of acute kidney injury.

Acute kidney injury (AKI) is a common and serious condition in both the inpatient and outpatient settings, and its diagnosis depends on serum creatinine measurements. Unfortunately, creatinine is a delayed and unreliable indicator of AKI. The lack of early biomarkers has limited our ability to translate promising experimental therapies to human AKI.

How to help the skin cope with glycoxidation.

Background: Protein glycation refers to the spontaneous reaction of reducing sugars with proteins and the subsequent formation of stable advanced glycation end products (AGEs). Glycation is linked with oxidative stress, and this association is called "glycoxidation". Glycoxidation alters the protein structure and function and causes tissue aging, as seen in human skin.

Adiponectin and cardiovascular outcomes among hemodialysis patients.

Background: Adiponectin (ADPN) levels are consistently elevated among patients with advanced chronic kidney disease, but its relationship with cardiovascular outcomes in this population remains controversial. The aim of our study was to measure the plasma levels of ADPN in patients with end-stage renal disease on maintenance hemodialysis (HD) and we studied its correlates to cardiovascular outcomes and mortality.

Methods: Our study included 133 HD patients (79 male and 54 female patients) with a mean age of 54.

Carotid intima media thickness, left ventricular hypertrophy and weekly averaged blood pressure in hemodialysis patients.

Undoubtedly, cardiovascular complications are the leading cause of mortality and morbidity in haemodialysis (HD) patients, and hypertension plays an important role in development of cardiovascular disorders in them. The present study evaluated the weekly averaged blood pressure with its relation to carotid intima media thickness and left ventricular mass index in HD patients. The study included 112 HD patients (85 males and 27 females).

Block copolymers of the type poly(caprolactone)-b-poly(ethylene oxide) for the preparation and stabilization of nanoemulsions.

Block copolymers poly(caprolactone)-block-poly(ethylene oxide) are promising non-ionic macromolecular surfactants for the stabilization of emulsions because they display a stronger adsorption and provide an increased long-term stability. But such amphiphilic copolymers should also allow the fabrication of the suspensions according to the emulsification process used. An evaluation of such block copolymers was done regarding the nanoprecipitation and the miniemulsion polymerization processes that both afford aqueous suspensions of nanoparticles.

Interactions of heparin with human skin cells: binding, location, and transdermal penetration.

The development of new materials for tissue engineering of skin substitutes requires an increasing knowledge of their interactions with human skin cells. Since carbohydrate recognition is involved in numerous biologic processes, including skin regeneration, the aim of this study was to identify sugar receptors expressed at the surface of human dermic and epidermic cells. Binding of fluorescent sugar-polyhydroxyethylacrylamide derivatives was analyzed by flow cytofluorimetry on cultured human skin fibroblasts, keratinocytes, and melanocytes.
