The chemical composition of virgin olive oil may be influenced by genotype and different agronomic (i.e. fruit ripeness degree, water supply) and technological factors. This article reports the evaluation of the influence of the olive ripening stage on the quality indices, the major and the minor components and the oxidative stability of the two main monovarietal Tunisian cultivars (cvv. Chétou...

This study shows the possibility of using gallic acid (GA) and/or methyl gallate (MG) accompanied by phosphatidylcholine (PC) instead tert-butylhydoquinone (TBHQ) for frying purposes. The antioxidants and PC were added in concentrations 1.2 mM 500–2000 mg/kg, respectively. Oxidative stability index (OSI) kinetics change conjugated dienes (LCD), carbonyls (LCO), value (AV) used to assess antioxi...

while sophisticated analytical methods like morgenstern-price or finite elementmethods are available for more realistic analysis of stability of slopes, assessment of the exactvalues of soil parameters is practically impossible. uncertainty in the soil parameters arisesfrom two different sources: scatter in data and systematic error inherent in the estimate of soilproperties. hence, stability o...

Periodontal disease is a chronic inflammatory disease of the jaws and is more prevalent in obesity. Local and systemic oxidative stress may be an early link between periodontal disease and obesity. The primary aim of this study was to detect whether increased periodontal disease susceptibility in obese individuals is associated with local and systemic oxidative stress. Accordingly; we analyzed ...

STUDY OBJECTIVES To investigate the relationship between the severity of obstructive sleep apnea (OSA) and oxidative stress, which plays an important role in the pathogenesis of cardiovascular disease, and to elucidate the factors contributing to this relationship. DESIGN Cross-sectional study. PARTICIPANTS A total of 128 consecutive subjects referred to the sleep laboratory of our hospital...
