(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008-07-25)Changes in cardiac osmolarity occur in myocardial infarction. Osmoregulatory mechanisms may, therefore, play a crucial role in cardiomyocyte survival. Tonicity-responsive enhancer binding protein (TonEBP) is a key ...
-
(ELSEVIER, 2008-07)Increased serum uric acid has been identified as an independent risk factor for cardiovascular disease. However, because of its antioxidant capacity, uric acid may play a beneficial role in endothelial function. This ...
-
(ELSEVIER, 2008-11-03)The removal of Cd(II) and Cu(II) ions from aqueous solutions was studied by sorption onto microcapsules prepared by copolymerizing ethylene glycol dimethacrylate (EGDMA) and styrene (ST). The microcapsules were prepared ...
-
(AMER CHEMICAL SOC, 2008-06-25)The amino acid composition and the physicochemical and functional properties of quinoa protein isolates were evaluated. Protein isolates were prepared from quinoa seed by alkaline solubilization (at pH 9, called Q9, and ...

Counterion and composition effects on discotic nematic lyotropic liquid crystals - I. Size and order (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2007-12-01)Counterion and composition effects on the size and interface dynamics of discotic nematic lyotropic liquid crystals made of tetradecyltrimethylammonium halide (TTAX)-decanol (DeOH)-water-NaX, with X = Cl- and Br-, were ...
-
(AMER CHEMICAL SOC, 1997-12-24)Deuterium quadrupole splittings from the aromatic ring of a series of linear benzyl-d(5) alkyl ethers, with alkyl chain length from 1 to 15 carbon atoms, have been measured using H-2-NMR spectroscopy. These molecules, 20% ...
-
(TAYLOR & FRANCIS LTD, 2003-01)The phase characterization of two homologous series of liquid crystalline methacrylic monomers based on omega-hexyl- and omega-butyloxysalicylaldimine groups, with different alkoxy tails, is presented. The liquid crystalline ...
-
(TAYLOR & FRANCIS LTD, 2003-05)The synthesis and measurement of thermodynamic properties of six methacrylate-based polymers were undertaken to observe the relationship between structural aliphatic features and mesophase properties. X-ray measurements ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2008-09)Greenhouse gases (GHG), basically methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O), occur at atmospheric concentrations of ppbv to ppmv under natural conditions. GHG have long mean lifetimes and are an important ...
