Here, we present the synthesis of a library of end-modified poly(!-amino ester)s and assess their utility as gene delivery vehicles. Polymers were synthesized using a rapid, two-step approach that involves initial preparation of an acrylate-terminated polymer followed by a postpolymerization amine-capping step to generate end-functionalized polymers. Using a highly efficient poly(!-amino ester)...

The present study aimed to investigate the chemical composition, and the antioxidant and antiproliferative activities of Ailanthus excelsa, a plant used in Egyptian traditional medicine. Chromatographic separation of a methanol extract of A. excelsa leaves yielded four flavones, namely apigenin (1), apigenin 7-O-beta-glucoside (2), luteolin (3), and luteolin 7-O-beta-glucoside (4), and seven fl...

A versatile method was developed for the quantitative analysis of semi-volatile linear aliphatic hydrocarbons in the n-C10 to n-C32 range and 16 polycyclic aromatic hydrocarbons (PAH) in hydraulic fracturing wastewaters using solid-phase extraction (SPE) on disposable octadecyl-bonded silica (C18) cartridges followed by gas chromatography-mass spectrometry. Matrix spikes revealed SPE recovery r...

The results suggest that in long run, more than one third all euroised countries central, eastern south-eastern Europe (CESEE) are linked shadow rate. ...

Background: Scientific research has confirmed the biological activity of resveratrol, which includes its antioxidant, anti-inflammatory, cardioprotective and anticancer properties. There is no known interaction between a static magnetic field resveratrol that can modulate resveratrol’s effect on cells. Thus, main aim our was to assess co-exposure oxidation–reduction homeostasis C32 Colo829 mela...

in this study, we assess the impact of oil price changes on the macroeconomic variables of some oil importers in oecd countries, including usa, italian, france and japan during the period 1960-2002. the results for different countries imply asymmetric impact of oil price changes on gdp growth rates; moreover, the results show that monetary shocks are an important and noticeable factor explainin...
