BACKGROUND Traffic-related air pollution is related with asthma, and this association may be modified by genetic factors. OBJECTIVES We investigated the role of genetic polymorphisms potentially modifying the association between home outdoor levels of modeled nitrogen dioxide and asthma. METHODS Adults from 13 cities of the second European Community Respiratory Health Survey (ECRHS II) were...
Isothiocyanates are anticarcinogenic phytochemicals found in cruciferous vegetables that both induce and are substrates for the gluthatione S-transferases (GSTs). The GSTs are phase II metabolizing enzymes involved in metabolism of various bioactive compounds. Functional polymorphisms in GST genes have been identified and may interact with cruciferous vegetable intake to affect cancer risk. We ...
The European eel illustrates an example of a critically endangered fish species strongly affected by human stressors throughout its life cycle, in which pollution is considered to be one of the factors responsible for the decline of the stock. The objective of our study was to better understand the transcriptional response of European eels chronically exposed to pollutants in their natural envi...
BACKGROUND Normal cellular metabolism is well established as the source of endogenous reactive oxygen species which account for the background levels of oxidative DNA damage detected in normal tissue. Hydrogen peroxide imposes an oxidative stress condition on cells that can result in DNA damage, leading to mutagenesis and cell death. Several potentially significant genetic variants related to o...
Remnant-like emulsions labeled with cholesteryl [(13)C]-oleate were prepared with lipid compositions similar to remnants derived from triacylglycerol-rich lipoproteins. When injected into the bloodstream of conscious mice, the remnant-like emulsions were metabolized in the liver leading to the appearance of (13)CO(2) in the breath. Previously, using this technique, we found that remnant metabol...
INTRODUCTION The objective was to compare by proteomics the expression of proteins associated with the cytoskeleton, energetic metabolism, and cardiac cytoprotection between left atrial appendages (LAA) and right atrial appendages (RAA) obtained from patients with mitral valve disease both in sinus rhythm (SR, n = 6) and in permanent atrial fibrillation (AF, n = 11). METHODS AND RESULTS Sampl...
objective(s):gentamicin sulphate (gs) nephrotoxicity seems to be related to the generation of reactive oxygen species. there is evidence that oxygen preconditioning increases the activity of antioxidant enzymes. materials and methods: forty eight female rats were divided into 6 groups (n=8) as follows: group 1 was the control, group 2 received daily gs, groups 3,4 and 5 received oxygen 2 hr/day...
Resveratrol (3,4',5-trans-trihydroxystilbene), a phytoalexin present in grapes and red wine, is emerging as a natural compound with potential anticancer properties. Here we show that resveratrol can induce growth inhibition and apoptosis in MDA-MB-231, a highly invasive and metastatic breast cancer cell line, in concomitance with a dramatic endogenous increase of growth inhibitory/proapoptotic ...
Background: Tissue healing consists of four main phases: coagulation, inflammation, proliferation, and remodeling. In diabetic patients, this process is stagnant in the inflammatory stage, leading to chronic wounds. The aim study evaluate an animal model biological evidence related use Rigenera® technology (Turin Italy), innovative mechanical procedure isolate autologous micrografts (AMG). Meth...
