Morbidity registration by a network of sentinel general practitioners (SGPs) in Belgium raises number problems related to possible biases the procedure, such as unequal geographical distribution, non-participation asegment target population and difficulties estimation denominator at risk for health under study. Through application two hierarchical clustering procedures, initial 43 districts country has been reduced 15 homogeneous district clusters. These represent new framework from which...
A method for the separation of selenium-containing proteins and subsequent detection quantification selenium was developed. First, are fractionated by means sodium dodecylsulfate polyacrylamide gel electrophoresis (SDS-PAGE); subsequently, bands gel, containing proteins, analyzed electrothermal vaporization (ETV)-ICP-MS to detect quantify selenium. External standardization with use an internal reference (Te) applied. limit ca. 40 pg Se per band a recovery 98% were obtained. single...
The binding of two activating cations, Co2+ and Mg2+, one inhibitory cation, Ca2+, to D-xylose isomerase from Streptomyces violaceoruber was investigated. Equilibrium-dialysis spectrometric studies revealed that the enzyme binds 2 mol Co2+/mol monomer. Difference absorption spectrometry in u.v. visible regions indicated environment first ion is markedly different second ion. appears have a six-co-ordinate. conformational change induced by site maximum after addition 1 equivalent yields...
D-Xylose isomerases from different bacterial strains were chemically modified with histidine and carboxylate-specific reagents. The active-site residues identified by amino acid sequence analysis of peptides recognized differential peptide mapping on ligand-protected unprotected derivatized enzyme. Both types found to cluster in a region consensus sequence: Phe-His-Asp-Xaa-Asp-Xaa-Xaa-Pro-Xaa-Gly, conserved all D-xylose studied so far. These results are consistent the recently published...
Background: Intrathoracic airway closure frequently occurs during cardiac arrest, possibly impairing ventilation. Previously, capnogram analysis was used to detect this pathophysiological process. In other populations, quasi-static pressure–volume curves obtained constant low-flow inflations are routinely intrathoracic closure. This study reports the first use of prehospital cardiopulmonary resuscitation. Methods: Connecting a pressure and flow sensor endotracheal tube enabled performance...
Abstract Speciation of arsenic was determined in serum 19 non-hemodialysis (non-HD) and 18 HD patients. The respective mean values creatinine these groups were 410 +/- 250 914 173 mumol/L (reference range for healthy subjects: females 50-80; males 57-93 mumol/L). total concentrations 5.12 +/-5.58 6.47 4.28 micrograms/L, respectively value: 0.958 +/-1.52 micrograms/L). Dimethylarsinic acid (DMA) arsenobetaine (AsB) the major As species non-HD patients, with 0.82 1.05 1.93 1.51 micrograms/L...
Increasing evidence indicates that lipophilic and/or protein-bound substances such as p-cresol are responsible for adverse physiological alterations in uraemic patients. To better understand the evolution of disposition renal failure and dialysis patients, it is necessary to determine its kinetic characteristics biotransformation pathways.We studied after intravenous injection compound eight rats with normal function. Urine was collected four 1 h intervals. evaluate presence metabolites,...
