Of special interest is the significant capability of the tested extracts to prevent the LDL oxidation at very low concentrations. Furthermore, the good correlation between the antioxidant activities assessed for the LDL oxidation inhibition and the intracellular ROS assays is indicative of the possible in vivo antioxidant properties of the extracts. Results herein reveal the considerable antioxidant potential of the Greek grapevine production and exploits their vinification by-products as a potential inexpensive source of high added value antioxidants.

“Chlorosulfonated polyethylene (CSPE)/organomontmorillonite (OMMT) nanocomposites were prepared by a
melt intercalation method. The microstructure selleck compound of the nanocomposites was characterized by transmission electron microscopy and X-ray diffraction. The effects of the OMMT content on the mechanical properties and swelling behavior of the nanocomposites were investigated. The improvement in the thermal stability of the nanocomposites was determined by thermogravimetric analysis. Transmission electron microscopy and X-ray diffraction showed that CSPE was intercalated into OMMT. When the OMMT content was lower than 12
wt%, the nanocomposites showed excellent tensile properties, which was attributed to nanometer-scale dispersion. The introduction of a small amount of Cell Cycle inhibitor OMMT also improved the thermal stability and swelling behavior, which was attributed to the
gas barrier action of the OMMT layers. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 115: 3365-3368, 2010″
“Purpose The purpose of this study is to examine whether parental education, socioeconomic status, or family environment moderate the extent of academic achievement deficits in pediatric brain tumor survivors (PBTS) relative to classmate case-controls. PBTS are known to be at risk for cognitive and academic impairment; however, the degree of impairment varies. Prior research has focused on treatment risk, and efforts to examine the protective role of family resources and relationships have been lacking.
Methods Pediatric brain tumor survivors (N=164), ages 8-15 and 1-5years posttreatment, were recruited at five treatment centers in the United States NSC-732208 and Canada. A case-control classmate, matched for age, gender, and race, was recruited for each survivor. The Wide Range Achievement Test, a demographic form, and the Family Environment Scale were administered in families’ homes. Treatment data were abstracted from medical charts.
Results Pediatric brain tumor survivors demonstrated lower achievement than classmate-controls in reading, spelling, and arithmetic. Parental education and socioeconomic status were associated with levels of achievement demonstrated by PBTS but did not account for discrepancies between PBTS and classmate-controls.
