Under a "cocktail-party" listening condition with multiple-people talking, compared to healthy people, people with schizophrenia benefit less from the use of visual-speech (lipreading) priming (VSP) cues to improve speech recognition. The neural mechanisms underlying the unmasking effect of VSP remain unknown. This study investigated the brain substrates underlying the unmasking effect of VSP i...

Vasospasm (VSP) is one of the major causes for prolonged neurologic deficit in patients with aneurysmal subarachnoid hemorrhage. Few case series have reported about continuous local intra-arterial nimodipine administration (CLINA) in refractory VSP. We report our experience with CLINA in a patient with refractory cerebral VSP.

Mycoplasma bovis, the most important etiological agent of bovine mycoplasmosis, undergoes extensive antigenic variation of major and highly immunogenic surface lipoprotein antigens (Vsps). A family of 13 related but divergent vsp genes, which occur as single chromosomal copies, was recently found in the chromosome of M. bovis. In the present study, the molecular mechanism mediating the high-fre...

BACKGROUND Relapsing fever (RF) spirochetes are notable for multiphasic antigenic variation of polymorphic outer membrane lipoproteins, a phenomenon responsible for immune evasion. An additional role in tissue localization is suggested by the finding that isogenic serotypes 1 (Bt1) and 2 (Bt2) of the RF spirochete Borrelia turicatae, which differ only in the Vsp they express, exhibit marked dif...

We discuss the Manned SpacePlane (MSP) project and its foundation for the Virtual SpacePlane (VSP) project. We present the requirements for the Virtual SpacePlane as derived from the MSP project’s objectives. The VSP requirements coupled with the need to rapidly assemble a prototype led us to reuse code from the Virtual Cockpit, Solar System Modeler, and Common Object Database (CODB) systems. W...

Aspect graph is an important method in 3D object recognition. To effectively compute the viewpoint space partition (VSP) is critical in acquiring a good aspect graph. In this paper, we present improvements to the VSP algorithm under perspective model: computing EV (Edge Vertex) events using triangle face feature; simplifying VSP representation; boundary intersection updating; closed loop region...

In Escherichia coli and related bacteria, the very-short-patch (VSP) repair pathway uses an endonuclease, Vsr, to correct T-G mismatches that result from the deamination of 5-methylcytosines in DNA to C-G. The products of mutS and mutL, which are required for adenine methylation-directed mismatch repair (MMR), enhance VSP repair. Multicopy plasmids carrying mutS alleles that are dominant negati...
