In recent years an effort has been made to isolate and identify biologically active compounds that are included in the Mediterranean diet. The existence of naturally occurring acetylated phenolics, as well as studies with synthetic ones, provide evidence that acetyl groups could be correlated with their biological activity. Platelet activating factor (PAF)(More)
Crude composition, lipid composition, and tocopherols, ascorbic acid, cholesterol, phytosterols, and squalene content together with fatty acids and antiplatelet activities of total, neutral, and polar lipids of avgotaracho (wax-covered, dried, and salted Mugil cephalus roe) were studied and compared with those of similar products. Wax and steryl esters(More)
AIM To investigate the relationship between low-grade inflammation and several glycemic indices in a population-based sample of men and women. METHODS The ATTICA study is a population-based cohort that randomly enrolled 1514 men and 1528 women (aged >18 years old), stratified by age and gender, from the Greater Athens area, during 2001-2002. Among several(More)
Minerals play a key role in the regulation of metabolic and physiological pathways. Adequate intake is required to maintain homeostasis, cell protection, functionality, and health, while deficiencies are associated with specific illnesses. Among the minerals, calcium, copper, iron, selenium, and zinc are considered especially important because of their(More)
The trace element selenium is an essential micronutrient for human health and its low levels in serum are implicated in the pathogenesis of several chronic diseases. Therefore, the determination of total selenium in serum may contribute to the assessment of the health and nutritional status of certain populations. The objective of the present work was to(More)
OBJECTIVE To examine the antioxidant role of propofol in ischemia-reperfusion during carotid endarterectomy (CEA) and its influence on cognitive dysfunction after CEA. DESIGN A randomized prospective study. SETTING Single-center study in a university hospital. PARTICIPANTS Forty-four patients. INTERVENTIONS Patients underwent elective CEA under(More)
It has been reported that exercise with eccentric contractions can induce damage and inflammation in human muscle tissue, the severity of which depends on the duration and the intensity of exercise. Platelet activating factor (PAF) is a potent inflammatory mediator implicated in a series of pathophysiological conditions. We sought to investigate the(More)
Cyanobacteria serve as a rich source of novel bioactive metabolites. Few studies on glycolipids reported them as having specific biological activities. In this study, total lipids of Scytonema julianum, a filamentous cyanobacterium isolated from a Greek cave, were separated into neutral and phospho- and glycolipids, and the latter were further fractionated(More)
BACKGROUND The antioxidant properties of propofol have been shown to improve ischemia/reperfusion injury. We investigated whether anesthesia with propofol can ameliorate remote lung injury induced by intestinal ischemia-reperfusion (IIR). MATERIALS AND METHODS Thirty male Wistar rats were randomly allocated in three groups (n = 10 each): animals in group(More)
Brain natriuretic peptides are widely used as biomarkers of cardiovascular diseases and mainly heart failure. However, these markers are often found to be high even in apparently healthy participants, and little is known about which factors contribute to physiological change in plasma brain natriuretic peptide (BNP) and amino-terminal pro-B-type natriuretic(More)
