The (Wiskott-Aldrich Syndrome Protein)-family verprolin homologous protein (WAVE) family of proteins occupies a pivotal position in the cell, converting extracellular signals into the formation of branched filamentous (F) actin structures. WAVE proteins contain a verprolin central acidic (VCA) domain at their C-terminus, responsible for binding to and activating the Arp2/3 complex, which in-tur...

Four commercially available enzyme immunoassays (EIAs) (Novitec, Biotest, Virotech, and DiaSorin) were evaluated, with an indirect immunofluorescence assay as the reference method, for Epstein-Barr virus (EBV) VCA (viral capsid antigen) immunoglobulin G (IgG), VCA IgM, or EBNA (EBV nuclear antigen) IgG at three different locations (Homburg, Stuttgart, and Dresden). Serum samples from 66 immunoc...

The prevalence and age distribution of Epstein-Barr virus infection varies in different populations and there is little information about the epidemiology of this infection in Brazil. We studied the prevalence of EBV antibodies in a sample of 283 children and adolescents between 1 and 21 years old. The sample was taken from two neighborhoods in Vitória (capital city of Espirito Santo, Brazil). ...

Using three-dimensional (3D) transesophageal echocardiography (TEE) and isometric handgrip exercise (IHE), we investigated the determinants of exercise-induced mitral regurgitation (MR) according to MR etiologies. Seventy-six patients with more than moderate MR, 40 functional (FMR) 36 degenerative (DMR), underwent 3D TEE combined IHE. Mitral valve (MV) geometry vena contracta area (3D VCA) were...

Creation of a scale analogous to the Bishop's (BS) based on transvaginal ultrasound. Assessment reproducibility and repeatability individual parameters correlation with corresponding axes BS. 116 patients in third trimester pregnancy had ultrasound examination assessment five selected BS (vaginal-cervical angle [VCA], dilatation assessed by 3D [DL], progression [AoP], strain elastography softwa...

We review results obtained with a recently proposed variational cluster approach (VCA) for the competition between d-wave superconductivity (dSC) and antiferromagnetism (AF) in the high-TC cuprates. Comparing the single-particle spectra of a two-dimensional Hubbard model with quantum Monte-Carlo (QMC) and experimental data, we verify that the VCA correctly treats the low-energy excitations. The...

Vascularized composite tissue allotransplantation (VCA) offers treatment options of complex functional deficiencies that cannot be repaired with conventional reconstructive methods. VCAs consist of blocks of functional units comprising different tissue types such as skin, bone, muscle, nerves, blood vessels, tendons, ligaments and others, and are thus substantially different from the compositio...

This study investigated the synthesis of membrane antigen (MA) as well as virus capsid antigen (VCA) and early antigen (EA) in Daudi cells which had been superinfected with the P3HR-1 strain of Epstein-Barr virus (EBV) and then treated with trypsin to remove initially absorbed MA-positive material from the cell surface. Synthesis of MA, VCA and EA was completely inhibited by puromycin. A marked...

Turbulence is a crucial component of dynamics of astrophysical fluids dynamics, including those of ISM, clusters of galaxies and circumstellar regions. Doppler shifted spectral lines provide a unique source of information on turbulent velocities. We discuss Velocity-Channel Analysis (VCA) and its offspring Velocity Coordinate Spectrum (VCS) that are based on the analytical description of the sp...

Introduction: SiGe pMOSFETs show considerable improvements in device performance due to the smaller hole effective mass exhibited by Ge.Further improvement in device performance can be obtained by growing pseudomorphically compressively strained SiGe on Si. Despite a lattice mismatch of ~4% between Si and Ge, researchers have been recently able to fabricate ultrathin body and nanowire pMOSFETs ...
