The overarching goal of the article is aimed at raising the awareness of basic researchers, as well as clinicians, to the versatility of this emerging alternative animal model of cancer.”
“The surface of a polypropylene (PP) film was activated

with chemical, electrochemical, and physical methods, and the effectiveness of these methods was compared. The effects of PP activation were assessed with attenuated total reflection IR spectroscopy (ATR-IR), SEM microscopy, and an analysis, based on the liquid contact angle, of the free energy components of the surface. The activation of the PP surface, which was dependent on the oxidizing medium, increased the energy of the PP surface layer and formed new chemical (carbonyl) groups, which were identified by IR (ATR) absorption spectroscopy and confirmed by selective surface dyeing. The treatments were ranked in the following order of increasing NCT-501 Metabolism inhibitor effectiveness: BI 6727 cost UV irradiation < 3M nitric acid < 30% hydrogen peroxide < silver nitrate (electrochemical method) < chromic mixture.

“This study investigates bipolar and nonpolar resistive-switching of HfO2 with various metal electrodes. Supported by convincing physical and electrical evidence, it is our contention that the composition of conducting filaments in HfO2 strongly depends upon the metal electrodes.

Nonpolar resistive-switching with the Ni electrode is attributed to the migration of metal cations and the corresponding electrochemical metallization. Conversely, oxygen-deficient filaments induced by anion migration are responsible for bipolar resistive-switching. It was also found that the characteristic nature of the

conducting filaments influences many aspects of switching characteristics, including the switching power, cycling variations, and retention at elevated temperatures. (C) 2011 American Institute of Physics. [doi:10.1063/1.3567915]“
“The Mouse Metabolic Phenotyping Center (MMPC) Consortium was established to address the need AG-881 solubility dmso to characterize the growing number of mouse models of metabolic diseases, particularly diabetes and obesity. A goal of the MMPC Consortium is to propose standard methods for assessing metabolic phenotypes in mice. In this article, we discuss issues pertaining to the design and performance of various tests of glucose metabolism. We also propose guidelines for the description of methods, presentation of data and interpretation of results. The recommendations presented in this article are based on the experience of the MMPC Consortium and other investigators.”
“In this work, we report the obtaining of an ecological imprinted polymer for the selective sorption of xanthine derivatives (caffeine and theobromine) from aqueous solutions, through an innovative approach. Poly (vinyl alcohol) [PVA]-xanthine films have been obtained by aqueous solution casting.
