To evaluate the concordance between viremia and antibody testing in hepatitis C virus (HCV) diagnosis, 682 serum or plasma samples collected from patients with known or suspected HCV infection were tested. An overall concordance of 77% between serological and PCR results was found, 5% was RNA positive/antibody negative and 18% antibody positive/RNA(More)
T lymphocytes are exquisitely sensitive to the antiproliferative effects of nitric oxide. We examined the effects of oral administration of two nitric oxide synthase inhibitors, Nw-nitro-L-arginine methyl ester (L-NAME) and L-N6-(1-iminoethyl)lysine (L-NIL), on the course of T cell-dependent autoimmune interstitial nephritis in Brown Norway rats.

Cells expressing markers of both natural killer and T lymphocytes (NK T cells) in humans and mice express a restricted T-cell receptor (TCR) repertoire, are of CD4- CD8- or CD4+ CD8- phenotype, and upon anti-CD3 stimulation secrete large amounts of interleukin-4 (IL-4) and interferon-gamma (IFN-gamma). NK T cells may be the primary source of IL-4-promoting(More)
Several investigators have employed interleukin-2 (IL-2) gene transfer to enhance the immunogenicity of tumor cell vaccines. We describe in this report the construction and characterization of retroviral vectors for IL-2 gene therapy. Human IL-2 cDNA with a chimeric rat preproinsulin/IL-2 DNA leader sequence was subcloned into the pLXSN (long terminal(More)
A 72-year-old man developed chronic sensory neuropathy (CSN) during chronic hepatitis C (HCV) infection. Neurological symptoms began one year after acute HCV hepatitis and slowly worsened over three years. No conventional cause for CSN was found. Circulating antinervous tissue antibodies (including anti-Hu) and inflammatory infiltrates in sural nerve biopsy(More)
BACKGROUND Roux-en-Y gastric bypass (RYGBP) has had a posilive impact on co-mobidities associated with obesity. However, in the long-term it can induce micronutrient deficiencies. AIM To petform a complete nutritional assessment in a group of women previously operated of RYGBP from different socioeconomic levels (SEL). PATIENTS AND METHODS Thirtyy three(More)
