Determination of Diclofenac on a Dysprosium Nanowire- Modified Carbon Paste Electrode Accomplished in a Flow Injection System by Advanced Filtering

open access: yesSensors, 2009
A new detection technique called Fast Fourier Transform Square-Wave Voltammetry (FFT SWV) is based on measurements of electrode admittance as a function of potential. The response of the detector (microelectrode), which is generated by a redox processes,

The influence of hydrogen treatment and catalyst morphology on the interaction of oxygen with a silver catalyst [PDF]

open access: yes, 1987
The interaction of an unsupported silver catalyst which had been pretreated by hydrogen at various temperatures with oxygen at 210°C has been studied using Temperature Programmed Reduction (TPR) over a temperature range up to 900°C. Hydrogen treatment at

Changes in Sperm Glutathione and Glutathione Redox States Correlate to Poor Sperm Qualitative Measures

open access: yesReproductive Medicine
Background/Objectives: In the past 50 years, human reproductive capacity has steadily declined with elusive and idiopathic origins. Amongst theorized causes, oxidative stress has been proposed to directly contribute to male infertility.

Post-Electrophoretic Identification of Oxidized Proteins

open access: yesBiological Procedures Online, 2000
The oxidative modification of proteins has been shown to play a major role in a number of human diseases. However, the ability to identify specific proteins that are most susceptible to oxidative modifications is difficult.

The oxidation of ascorbic acid and its reduction in vitro and in vivo [PDF]

open access: yes, 1937
The outstanding chemical property of ascorbic acid (vitamin C) is that it is a reducing agent. The suggestion is obvious that its physiological function may be associated with this property, and, if it is oxidized reversibly, with its behavior in an ...

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild
