We have examined how transient cerebral ischemia affects the mRNA expression of a family of methyl CpG-binding domain (MBD)-containing factors in the rat hippocampus. Our results show that each member of this family is affected by cerebral ischemia challenge, but with differing patterns of responsiveness. At 3, 6 and 12 h following reperfusion, MeCP2 and(More)
BACKGROUND To better inform clinicians on the optimal management of patients on oral anticoagulation who need to undergo surgery or invasive procedures, the authors performed a decision analysis examining whether a perioperative aggressive or minimalist strategy results in greater quality-adjusted survival. METHODS A decision analysis model was created(More)
Hyponatremia, in its most severe form, requires urgent infusion of hypertonic saline to correct cerebral edema. However, overly rapid correction of chronic hyponatremia can cause osmotic demyelination syndrome. The authors review the treatment of hyponatremia in order to provide clinicians with a sound approach in a variety of settings in which severity,(More)
A novel method for preparing highly photoactive nano-sized TiO2 photocatalysts with anatase and brookite phases has been developed by hydrolysis of titanium tetraisoproproxide in pure water or a 1:1 EtOH-H2O solution under ultrasonic irradiation; the photocatalytic activity of TiO2 particles prepared by this method exceeded that of Degussa P25.
We have examined the effects of transient global ischemia on both the gene expression levels and the functionality of GABA(B) receptors in rat brain, using antisense in situ hybridization and electrophysiological evaluations. At the level of gene expression, no significant change in GABA(B) receptor expression was observed in any hippocampal subfield at(More)
We have investigated the gene expression responses of a family of methyl CpG-binding domain-containing factors (MeCP2, MBD1, MBD2, and MBD3) in the hippocampus of electrically kindled rats. Expression was examined in both amygdala- and partial perforant-pathway-kindled subjects, 24 h and 28 days following the final stimulation. In general, the responses of(More)
Kondo lattice systems can exhibit unusual many-body behaviors that result from the interplay between onsite Kondo screening and intersite coupling. We used scanning tunneling microscopy to image the Kondo resonance in a nonconventional Kondo lattice formed by self-assembled oxygen (O(2)) molecules, which are paramagnetic, on the gold reconstructed surface(More)
The authors used mRNA differential display to identify genes whose expression levels are altered in the adult rat hippocampus 24 hours after global ischemia. At this time after challenge, the basic helix-loop-helix transcription factor, SEF-2, and the 26S proteasome complex subunit, p112, were identified as genes whose expression levels are decreased and(More)
Selective excitations of specific vibronic modes in position space are realized in single naphthalocyanine molecules adsorbed on an ultrathin alumina film by a scanning tunneling microscope at low temperature. Distinct spatial distributions are imaged for the different vibronic modes, which are in accordance with spectra recorded over different points of(More)
Using mRNA differential display to identify cerebral ischemia-responsive mRNAs, we isolated and cloned a cDNA derived from a novel gene, that has been designated LCHN. Antisense mRNA in situ hybridization and immunoblotting confirmed LCHN expression to be induced in the rat hippocampus following transient forebrain ischemia. The deduced amino acid sequence(More)
