The research investigates the efficacy of brain transcatheter laser revascularization in patients who have had extensive ischemic stroke. 1125 patients aged 29 81 (average age 75) with cerebral atherosclerosis were examined. The examination plan included: CT brain scan, magnetic resonance imaging (MRI), brain scintigraphy (SG), rheoencephalography (REG), cerebral multi-gated angiography (MUGA),...

Identifying the progenitors of Type Ib and Type Ic supernovae requires knowing, among other things, whether SNe Ib eject hydrogen, and whether SNe Ic eject helium, and perhaps even hydrogen. Recently it has become clear that some SNe Ib do eject hydrogen, and it may be that all SNe Ib do. Two arguments that have been made in the past that SNe Ic eject helium are difficult to confirm, but I disc...

Given an index set X, a collection IB of subsets of X, and a collection (` x : x 2 X) of commuting linear maps on some linear space, the family of linear operators whose joint kernel K = K(IB) is sought consists of alì A := Q a2Aà with A any subset of X which intersects every B 2 IB. It is shown that certain conditions on IB and`, used in BRS] to obtain the inequality dim K(IB) X B2I B dim K(fB...

Glycoprotein (GP) Ib , a member of the leucine-rich repeat (LRR) protein family, mediates platelet adhesion to immobilized von Willebrand factor (VWF). We investigated the role in VWF binding of charged residues in the LRR region of GP Ib that are conserved in human, canine, and murine proteins. Substitution of His86 with either Ala or Glu resulted in a gain of VWF-binding function as judged by...

Inattentional blindness (IB) describes the failure to notice salient but unexpected stimuli when attention is partially engaged by another task. Few studies have explicitly investigated the role of eye movements in IB and the relative contributions of overt and covert attention. We recorded eye movements in a series of IB experiments using dynamic stimuli. Results indicate that eye movements do...

Dysregulation of growth and differentiation factor 5 (GDF-5) signalling, a member of the TGF-beta superfamily, is strongly linked to skeletal malformation. GDF-5-mediated signal transduction involves both BMP type I receptors, BMPR-IA and BMPR-IB. However, mutations in either GDF-5 or BMPR-IB lead to similar phenotypes, indicating that in chondrogenesis GDF-5 signalling seems to be exclusively ...

OBJECTIVES To characterize the prevalence of plasmid-mediated quinolone resistance determinants qnr and aac(6')-Ib-cr in extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae. METHODS qnrA, qnrB, qnrS, aac(6')-Ib-cr and ESBL-encoding genes were detected by PCR. MICs of 10 antimicrobial agents were determined by Etest. PFGE was used to investigate the clo...

N-RAP is a muscle-specific protein with an N-terminal LIM domain (LIM), C-terminal actin-binding super repeats homologous to nebulin (SR) and nebulin-related simple repeats (IB) in between the two. Based on biochemical data, immunofluorescence analysis of cultured embryonic chick cardiomyocytes and the targeting and phenotypic effects of these individual GFP-tagged regions of N-RAP, we proposed...

With the emergence of multi-core-based processors, it is becoming significantly important to optimize both intra-node and inter-node communication in an MPI stack. MPICH2 group has recently introduced a new Nemesis-based MPI stack which provides highly optimized design for intra-node communication. It also provides modular design for different inter-node networks. Currently, the MPICH2/Nemesis ...
