Repeatedly performing similar motor acts produces short-term adaptive changes in the agent's motor system. One striking use-dependent effect is the motor-to-visual aftereffect (MVA), a short-lasting negative bias in the conceptual categorization of visually-presented training-related motor behavior. The MVA is considered the behavioral counterpart of the adaptation of visuomotor neurons that co...

AIMS PTMC produces significant changes in mitral valve morphology as improvement in leaflets mobility. The determinants of such improvement have not been assessed before. METHODS AND RESULTS The study included 291 symptomatic patients with mitral stenosis undergoing PTMC. Post-PTMC subvalvular splitting area was a determinant of post-PTMC excursion in both the anterior (B 0.16, 95% CI 0.03 to...

Angiogenesis represents an important process manifested in tumour growth and in development of metastases. Using immunohistochemistry, the authors evaluated number of vessels in various nodular lesions of the thyroid (54 cases). Expression of CD34 antigen and microvessel density were evaluated in sections of archival paraffin blocks originating from the Department of Pathological Anatomy, Unive...

BACKGROUND Percutaneous mitral annuloplasty has been proposed as an alternative to surgical annuloplasty. In this respect, evaluation of the coronary sinus (CS) and its relation with the mitral valve annulus (MVA) and the coronary arteries is relevant. The feasibility of evaluating these issues noninvasively with multislice computed tomography was determined. METHODS AND RESULTS In 105 patien...

The work flow of migration velocity analysis (MVA) is widely used in seismic exploration of hydrocarbon reservoirs to refine velocity models and obtain precise information about subsurface structures. Therefore the velocity uncertainty introduced in the MVA process directly affects assessments of structural uncertainty and reservoir volumes. In order to quantify the velocity uncertainty in MVA ...

AIMS To explore the potentiality of cardiovascular magnetic resonance (CMR) in the quantitative evaluation of mitral valve annulus (MVA) and tricuspid valve annulus (TVA) morphology and dynamics. METHODS AND RESULTS CMR was performed in 13 normal subjects and 9 patients with mitral (n = 7) or tricuspid regurgitation (n = 2), acquiring cine-images in 18 radial long-axis planes passing through ...

Vaccinia virus (VACV) encodes an anti-apoptotic Bcl-2-like protein F1 that acts as an inhibitor of caspase-9 and of the Bak/Bax checkpoint but the role of this gene in immune responses is not known. Because dendritic cells that have phagocytosed apoptotic infected cells cross-present viral antigens to cytotoxic T cells inducing an antigen-specific immunity, we hypothesized that deletion of the ...

High performance computing (HPC) encompasses advanced computation over parallel processing, enabling faster execution of highly compute intensive tasks such as climate research, molecular modeling, physical simulations, cryptanalysis, geophysical modeling, automotive and aerospace design, financial modeling, data mining and more. High performance simulations require the most efficient compute p...

Multivariate analysis (MVA) is a class of statistical and pattern recognition methods that involve the processing of data that contains multiple measurements per sample. MVA can be used to address a wide variety of medical neuroimaging-related challenges including identifying variables associated with a measure of clinical importance (i.e. patient outcome), creating diagnostic tests, assisting ...

We investigate the possibility of including multivariate analysis (MVA) in the standard X-Pipeline gravitational wave (GW) burst search analysis for a single detector. MVA has been very effective in data analysis involving high energy particle physics, and is very promising in showing similar results in the GW data analysis community as well. We use the software package Toolkit for Multivariate...
