Exploration-dependent induction of the immediate early gene Arc (activity-regulated cytoskeleton associated protein) in hippocampal neurons was examined in the general population of neurons versus neurons that were generated similar to 1 week after the ischemic insult and labeled with bromodeoxyuridine. Although Arc was inducible in a network-specific manner after severe neonatal stroke, it was impaired, not only in the ipsilateral injured but also in the contralateral uninjured hippocampi when examined 6 months after the neonatal stroke. Severity of both the stroke injury and the

acquired poststroke epilepsy negatively correlated with Arc induction and HDAC inhibitor new neuron integration into functional circuits in the injured hippocampi. (C) 2010 Elsevier Inc. All rights reserved.”
“Optical second- and third-harmonic generation on epitaxial films of the ferromagnetic semiconductor europium oxide reveal

selective coupling to the magnetic and crystallographic properties of the compound. Second-harmonic generation couples linearly to the order parameter parametrizing the long-range ferromagnetic order. In contrast, third-harmonic generation couples to the crystallographic lattice and to the short-range spin-spin correlations manifesting macroscopically IPI-549 price as a magnetostrictive effect. These results demonstrate the potential of nonlinear optics for acquiring unique information about the crystallographic, electronic, and magnetic properties of spintronics compounds.

“The emulsion polymerization of the monomers methyl methacrylate (MMA) and 2-ethylhexyl acrylate (EHA) was studied to investigate the effect of the crosslinkable monomer poly(propylene

glycol diacrylate) (PPGDA). IR spectroscopy, NMR, differential scanning calorimetry, gel permeation chromatography, and scanning electron microscopy were used to characterize the synthesized polymers. These polymers were coated on glass panels and cured at appropriate temperatures to study the physical properties, swelling behavior, surface tension, and contact angle of these polymer Selleck Alisertib latices. The results show that as the concentration of EHA monomer increased, the surface tension of the latices decreased. The copolymers were characterized by (1)H-NMR spectroscopy to ensure the absence of unreacted monomer, and the results confirm the incorporation of EHA units in the copolymer. The contact angle of the latices on the glass substrate was smaller than that on the metal. The swelling mechanism of the film showed that the Fickian diffusion coefficient with 10 wt % PPGDA was at a minimum value and was the most highly crosslinked polymer among the samples.
