Assessment of the antioxidant activity of an olive oil total polyphenolic fraction and hydroxytyrosol from a Greek Olea europea variety in endothelial cells and myoblasts
(2017)Olive oil (OO) constitutes the basis of the Mediterranean diet, and it seems that its biophenols, such as hydroxytyrosol (HT) may scavenge free radicals, attracting distinct attention due to their beneficial effects in ... -
Assessment of the impact of three pesticides on microbial dynamics and functions in a lab-to-field experimental approach
(2018)The toxicity of pesticides on soil microorganisms is as an emerging area of concern. Novel and well-standardized tools could be now used to provide a robust assessment of the ecotoxicity of pesticides on soil microorganisms. ... -
The autophagic response to oxidative stress in osteoarthritic chondrocytes is deregulated
(2018)It has been reported that oxidative stress (OS) is involved in the pathogenesis of osteoarthritis (OA) and that defective autophagy is accompanying this age-related disease. Moreover, it has been proposed that induction ... -
Cyanotoxins as the “common suspects” for the Dalmatian pelican (Pelecanus crispus) deaths in a Mediterranean reconstructed reservoir
(2018)Toxic cyanobacterial blooms have been implicated for their negative consequences on many terrestrial and aquatic organisms. Water birds belong to the most common members of the freshwater food chains and are most likely ... -
Dissipation and adsorption of isoproturon, tebuconazole, chlorpyrifos and their main transformation products under laboratory and field conditions
(2016)Assessment of dissipation constitutes an integral part of pesticides risk assessment since it provides an estimate of the level and the duration of exposure of the terrestrial ecosystem to pesticides. Within the frame of ... -
Distribution and stability of aflatoxin M1 during processing, ripening and storage of Telemes cheese
(2001)Telemes cheeses were produced using milk that was artificially-contaminated with aflatoxin M1 at the levels of 0.050 and 0.100 μg/l. The cheeses produced in the two cheese-making trials were allowed to ripen for 2 months ... -
Downgrading the systemic condition of rabbits after long term exposure to cypermethrin and piperonyl butoxide
(2016)Aim The aim of this study is to clarify the effect of cypermethrin (CY) on the oxidative stress (OS) and inflammation status of animals exposed to it and the synergistic role of piperonyl butoxide (PB0). Main methods Markers ... -
Effect of polyphenols from coffee and grape on gene expression in myoblasts
(2018)Coffee and grape contain various bioactive compounds like polyphenols that may exert beneficial effects, especially antioxidant activity, on human health upon consumption. However, the molecular mechanisms through which ... -
Exhaled breath condensate in asthma: From bench to bedside
(2011)The need for non-invasive assessment of airway inflammation is imperative, since inflammatory airway diseases, such as asthma and COPD, are characterized by variation in their clinical presentation throughout their course. ... -
Influence of Zeolite and Posidonia oceanica (L.) in the Reduction of Heavy Metal Uptake by Tobacco (Nicotiana tabacum) Plants of Central Greece
(2017)In two soils from Central Greece, a pot experiment was conducted with the addition of mixture at various ratios of zeolite and compost (based on Posidonia oceanica (L.) leaves) applied at a rate of 5% w/w (calculated on a ... -
Interrelations among the adipocytokines leptin and adiponectin, oxidative stress and aseptic inflammation markers in pre- and early-pubertal normal-weight and obese boys
(2017)Purpose: Presumed interrelationships among deleterious aspects of adipose tissue metabolism, inflammation, and cellular oxidative stress could be influenced by pubertal hormonal changes. They were investigated in pre- and ... -
Investigation of the chemical profile and cytotoxicity evaluation of organic components eluted from pit and fissure sealants
(2018)The aim of this study was to identify organic components eluted from five resin dental sealants using gas chromatography and mass spectrometry (GC/MS) after 1-day and 40-days storage and the effect of sealants on cell ... -
Lettuce facing microcystins-rich irrigation water at different developmental stages: Effects on plant performance and microcystins bioaccumulation
(2017)This study investigated the microcystins (MCs)-rich irrigation water effect on lettuce of different developmental stages, i.e. during a two months period, covering the whole period from seed germination to harvest at ... -
Modulation of hexavalent chromium toxicity on οriganum vulgare in an acidic soil amended with peat, lime, and zeolite
(2018)Dynamics of chromate (Cr(VI)) in contaminated soils may be modulated by decreasing its phytoavailability via the addition of organic matter-rich amendments, which might accelerate Cr(VI) reduction to inert chromite (Cr(III)) ... -
Noninvasive histologic grading of solid astrocytomas using proton magnetic resonance spectroscopy
(2004)Background: Proton magnetic resonance spectroscopy (1H MRS) constitutes a promising modality to assess intracranial pathology. We present our experience using this method in grading solid brain astrocytomas. Material and ... -
Tobacco-specific nitrosamines: A literature review
(2018)Cigarette smoke is a complex mixture of chemicals, including several tobacco-specific nitrosamines (TSNA). Most TSNA are formed in tobacco during the post-harvest period, while a number are produced when a cigarette is ... -
Unraveling the mechanisms of extreme radioresistance in prokaryotes: Lessons from nature
(2016)The last 50 years, a variety of archaea and bacteria able to withstand extremely high doses of ionizing radiation, have been discovered. Several lines of evidence suggest a variety of mechanisms explaining the extreme ... -
Urate crystals directly activate the T-cell receptor complex and induce T-cell proliferation
