The inwardly rectifying potassium (Kir) 2.x channels mediate the cardiac inward rectifier potassium current (I(K1)). In addition to differences in current density, atrial and ventricular I(K1) have differences in outward current profiles and in extracellular potassium ([K+]o) dependence. The whole-cell patch-clamp technique was used to study these(More)
BACKGROUND Schizophrenia is a complex major psychiatric disorder affecting ∼1% of the world population. Recently, in a genome-wide association study and a follow-up in Caucasians, Stefansson et al. examined 7662 schizophrenic cases and 29053 normal control subjects and reported seven common single nucleotide polymorphisms (SNPs) that were significantly(More)
DYX1C1 has been associated with dyslexia and neuronal migration in the developing neocortex. Unexpectedly, we found that deleting exons 2-4 of Dyx1c1 in mice caused a phenotype resembling primary ciliary dyskinesia (PCD), a disorder characterized by chronic airway disease, laterality defects and male infertility. This phenotype was confirmed independently(More)
Hepatitis C virus (HCV) replication is dependent on microRNA 122 (miR-122), a liver-specific microRNA that recruits Argonaute 2 to the 5' end of the viral genome, stabilizing it and slowing its decay both in cell-free reactions and in infected cells. Here we describe the RNA degradation pathways against which miR-122 provides protection. Transfected HCV RNA(More)
Regulation of RNA degradation plays an important role in the control of gene expression. One mechanism of eukaryotic mRNA decay proceeds through an initial deadenylation followed by 5' end decapping and exonucleolytic decay. Dcp2 is currently believed to be the only cytoplasmic decapping enzyme responsible for decapping of all mRNAs. Here we report that(More)
OBJECTIVE The structural, cytoarchitectural and functional brain abnormalities reported in patients with mental disorders may be due to aberrant neuronal migration influenced by cell adhesion molecules. MDGA1, like Ig-containing cell adhesion molecules, has several cell adhesion molecule-like domains. Moreover, Kahler et al. (2008) reported that the MDGA1(More)

The high incidence of thromboembolic complications of mechanical heart valves (MHV), primarily due to platelet activation by contact with foreign surfaces and by non-physiological flow patterns past the valve, still limits their success as permanent implants. The latter include elevated shear and turbulent stresses and shed vortices formed in the wake of(More)
