Relationship of metabolic syndrome and its components with thyroid dysfunction in Algerian patients.

Aims: The aim of this study is to evaluate the prevalence of the metabolic syndrome and its compounds in subjects with different thyroid status.

Materials And Methods: A prospective cross-sectional study was conducted in the internal medicine department at El Okbi Hospital of Guelma (East of Algeria) from January 2014 to September 2015. Eighty six patients attending the specialist consultation for suspected thyroid disorders were included in the study.

Electrochemical boron-doped diamond film microcells micromachined with femtosecond laser: application to the determination of water framework directive metals.

Planar electrochemical microcells were micromachined in a microcrystalline boron-doped diamond (BDD) thin layer using a femtosecond laser. The electrochemical performances of the new laser-machined BDD microcell were assessed by differential pulse anodic stripping voltammetry (DPASV) determinations, at the nanomolar level, of the four heavy metal ions of the European Water Framework Directive (WFD): Cd(II), Ni(II), Pb(II), Hg(II). The results are compared with those of previously published BDD electrodes.

Impedance spectroscopy and conductometric biosensing for probing catalase reaction with cyanide as ligand and inhibitor.

In this work, a new biosensor was prepared through immobilization of bovine liver catalase in a photoreticulated poly (vinyl alcohol) membrane at the surface of a conductometric transducer. This biosensor was used to study the kinetics of catalase-H(2)0(2) reaction and its inhibition by cyanide. Immobilized catalase exhibited a Michaelis-Menten behaviour at low H(2)0(2) concentrations (<100mM) with apparent constant K(M)(app)=84±3mM and maximal initial velocity V(M)(app)=13.
