OBJECTIVE To investigate the association between human herpesviruses and multiple sclerosis (MS), as well as between measles virus and MS. METHODS The authors identified prospectively collected serum samples from 73 MS cases and retrospective sera from 161 MS cases in two population-based serum bank registers. Analyses of IgG antibody responses in cases and matched referents were performed fo...

Epstein-Barr virus (EBV)-specific immunoblot analysis was used to reveal the molecular diversity of immunoglobulin (Ig) G and IgA antibody responses against Epstein-Barr nuclear antigen (EBNA), early antigen (EA), and viral capsid antigen (VCA) in serum samples from patients with nasopharyngeal carcinoma (NPC) and control subjects, by use of immunofluorescence assay (IFA). Control donors (np150...

MATERIALS AND METHODS: 8 cynomolgus monkeys received either an orthotopic hand (n=2) or heterotopic face VCA (n=6) from MHC-mismatched donors following induction with anti-thymocyte globulin. Postoperatively, triple immunosuppression – tacrolimus, mycophenolate mofetil, methylprednisolone – was maintained for up to 120 days before bone marrow transplantation (BMT) was performed. Protocol biopsi...

Since the start of the clinical vascularized composite allotransplantation (VCA) era over a decade ago this field has witnessed significant developments in both basic and translational research. Transplant tolerance, defined as rejection-free acceptance of transplanted organs or tissues without long-term immunosuppression, holds the potential to revolutionize the field of VCA by removing the ne...

The vertical-centre-anterior margin (VCA) angle quantifies the anterior cover of the femoral head. However, when the femoral head is deformed it may be difficult to identify its centre. We have therefore created a new index, the anterior acetabular head index (AAHI) which is measured on the false-profile radiograph. We measured the VCA and AAHI angles in 312 hips in which the centre-edge angle ...

We have computed phonon scattering rates and density of states in silicon germanium alloys using Green’s function calculations and density functional theory. This method contrasts with the virtual crystal approximation (VCA) used in conjunction with Fermi’s golden rule, which cannot capture resonance states occurring through the interaction of substitutional impurities with the host lattice. Th...

The VCA domain of the neuronal Wiskott-Aldrich syndrome protein (N-WASP) is a potent activator of the Arp2/3 complex, a 240 kDa heteroheptameric actin-nucleating assembly. We used site-directed spin labeling of N-WASP peptides in conjunction with methyl-TROSY spectra of the intact, selectively labeled Arp2/3 complex to identify regions of the VCA that are proximal to the ARPC3 subunit of the as...

Vascularized composite allotransplantation (VCA) has the potential to reconstruct any non-visceral tissue defect, using like for like tissue, delivering optimal form and function. Over 150 VCA transplants have been performed worldwide; however, this treatment remains experimental. Things systematically tried in the clinic should follow thorough science and tested in a model that allows predicti...

We have previously reported the identification and characterization of two related human cell surface protein complexes, very common antigens 1 and 2 (VCA-1, VCA-2) (Kantor, R. R. S., Mattes, M. J., Lloyd, K. O., Old, L. J., and Albino, A. P. (1987) J. Biol. Chem. 262, 15158-15165). We now report the transfection of DNA sequences encoding the 170-kilodalton heterodimer of VCA-2 from human SK-RC...
