Mechanisms of tumor development were studied in SCID mice injected with human lymphoid cells from Epstein-Barr virus-positive (EBV+) donors. About 80% of peripheral blood mononuclear cell (PBMC)-injected animals developed a lymphoproliferative disease associated with oligoclonal EBV+ tumors of human B cell origin. No change in tumor development rate(More)
OBJECTIVE The objective of this article is to determine whether cutaneous allodynia (CA) influences the response to treatment with occipital transcutaneous electrical stimulation (OTES) in chronic migraine (CM) and chronic tension-type headache (CTTH). METHODS One hundred and sixty consecutive patients with CM or CTTH were randomized to be treated with(More)
Canavan's disease is an autosomal recessive disorder characterized by a deficiency of aspartoacylase and accumulation of N-acetylaspartic acid (NAA), leading to a severe leukodystrophy and spongy degeneration of the brain. N-Acetylaspartylglutamate (NAAG), the presumed product of NAA, also accumulates in this disease. The endogenous dipeptide NAAG has been(More)
The in vitro suppressive effect of gp120 and gp120/anti-gp120 antibody is well known but not yet proven to operate in vivo. We report findings consistent with the presence of gp120/anti-gp120 antibody complexes on CD4+ lymphocytes from HIV-infected patients with advanced disease. PBMC from most AIDS patients showed selective masking of the CD4 epitope(More)
MLR3 molecule is a membrane glycoprotein (mol. mass range 28-34 kDa) present on activated, but not resting human peripheral T cells, B cells and thymocytes. Its kinetics of appearance on the cell surface (3 h after the addition of the inductive signal to the cells) suggests that it is an early activation antigen. The proliferative response of cultured T and(More)
Spontaneous in vitro production of HIV-1-specific antibodies, a hallmark of infected subjects, is often down-regulated by the addition of pokeweed mitogen. We observed that a decrease in such ongoing anti-HIV-1 antibody synthesis could also be induced in cultures from most patients by addition of phytohemagglutinin and Concanavalin A, but not by(More)
Optimal conditions for in vitro anti-human immunodeficiency virus type 1 (HIV-1) antibody (Ab) synthesis and detection were re-appraised. Western blot (WB) and radioimmunoassay (RIA) could detect about 1 and 10 ng, respectively, of HIV-1-specific Ab (HIV-Ab), while the sensitivity of an enzyme-linked immunosorbent assay (ELISA) was much lower. Optimal(More)
A cytogenetic study was undertaken to quantify, by chromosomal karyotyping, the incidence and type of chromosomal abnormalities present in Day-6 in vitro-produced (IVP) porcine embryos. Morphologically normal Day-6 blastocysts (n=318) were fixed and grouped into six classes according to the number of total cells (from < or =20 to 61-70). Of 248 embryos(More)
In this report we studied the antigen identified by the 5/9 monoclonal antibody. This antigen is expressed on approximately 15% of resting T lymphocytes with helper activity and increases following T-cell activation both in vivo and in vitro. The 5/9 monoclonal antibody triggered T-cell proliferation in the presence of suboptimal doses of phorbol12-myrisate(More)
The Italian Dystonia Registry is a multicenter data collection system that will prospectively assess the phenomenology and natural history of adult-onset dystonia and will serve as a basis for future etiological, pathophysiological and therapeutic studies. In the first 6 months of activity, 20 movement disorders Italian centres have adhered to the registry(More)
