In accordance with the European Parliament and Council's directive, vitamin A and C supplements can include any of four (vitamin A) or five (vitamin C) specified compounds. This study focuses on these compounds and compares their abilities to affect the DNA and viability of cells in culture, but also their potencies to chemically oxidise the DNA nucleoside deoxyguanosine (dG). To study the vita...
background: improvement of endothelial dysfunction could prevent or delay the occurrence of the atherosclerosis process in patients with kawasaki disease (kd). it is suggested that vitamin c could improve endothelial dysfunction. in this study, we investigated whether administration of vitamin c as a water-soluble antioxidant could be effective in this regard among patients with kd. materials a...
Background: Recently, the role of inflammation and oxidative stress in the pathophysiology of atrial fibrillation (AF) after cardiac surgery has been emphasized. Vitamin C as an antioxidant important role in reducing the incidence of postoperative atrial fibrillation. This study aimed to investigate, administration of vitamin C, as a way to reduce the incidence of atrial fibrillation after coro...
The purpose of this prospective analytic study was determination of relationship between smoking and level of vitamin C in plasma and dietary intake. Twenty one smokers and twenty two non-smokers from Shahid Beheshti University of Medical Sciences and Health Services staff were selected and pair – matched their by age , sex, occupation, education , vitamin C supplementation, history of...
BACKGROUND Several local anaesthetic techniques are available for cataract surgery. Recently, topical anaesthesia has gained in popularity. A randomized trial was designed to compare patient discomfort and intraoperative complications following routine cataract surgery under topical or sub-Tenon's anaesthesia. METHODS A randomized double-blinded placebo-controlled clinical trial of 210 patien...
Epidemiological studies showed protective effect of vitamin C on improvement of serum lipoproteins and decrease of coronary heart disease(CHD), but its interaction with copper absorption and metabolism is also reported. The aim of the present study was to determine the effects of vitamin C on lipoproteins and its interaction with copper in hyperlipidemic patients. In a double bli...
The discovery and synthesis of vitamin C has made possible a significant advance in calcium therapy sufficient to warrant re-examination of the value of calcium therapy in otolaryngology. Vitamin C possesses the unique property of solubilizing and ionizing calcium to a degree not previously attainable by oral or intra-muscular administration. In calcium cevitamate, the calcium salt of vitamin C...
Résumé : Une large variété de schémas d’approximation de la fonction de valeur a été appliquée à l’apprentissage par renforcement. Cependant, les approches par filtrage bayésien, qui se sont pourtant montrées efficaces dans d’autres domaines comme l’apprentissage de paramètres pour les réseaux neuronaux, ont été peu étudiées jusqu’à présent. Cette contribution introduit un cadre de travail géné...
We report structural data on liquid iron at pressures up to 58 GPa measured by x-ray scattering in a laser heated diamond anvil cell. The determined structure factor preserves essentially the same shape along the melting curve. Our data demonstrate that liquid iron at high pressures is a close-packed hard-sphere liquid. The results place important constraints on the thermodynamic and transport ...
