Abstract HIV-specific T cells response and cell activation are frequently seen in exposed seronegative individuals (ESN). In this study, we report level of ESN partners HIV-infected patients presenting low or undetectable levels HIV-RNA. We evaluated 24 HIV-serodiscordant couples. were classified into three categories exposure to HIV (very low, moderate-high), considering HIV-RNA their infected partner frequency sexual high-risk practices within the last 12 mo. responses subsets by flow...
Abstract Background. Human immunodeficiency virus type 1 (HIV-1) controllers maintain HIV-1 viremia at low levels (normally <2000 HIV-RNA copies/mL) without antiretroviral treatment. However, some have evidence of immunologic progression with marked CD4+ T-cell decline. We investigated host genetic factors associated protection against loss in controllers. Methods. analyzed the association interferon-lambda 4 (IFNL4)–related polymorphisms and human leukocyte antigen (HLA)-B haplotypes...
Abstract Eight genotypes (A–H) of hepatitis B virus (HBV) have been described, HBV F and H being autochthonous to America. genotype has classified in four clusters. The objective this study was gain insight into the molecular epidemiology American genotypes, as well analyze genotype‐related polymorphism some functional domains surface proteins. sequences S region 106 isolates were analyzed, out which 47 circulated different Venezuelan populations. Most grouped cluster III (n = 39) 7 II. One...
Susceptibility to HIV transmission by sexual intercourse has been associated with cellular anti-HIV responses. We aimed also evaluate potential systemic humoral responses against in a group of HIV-exposed seronegative individuals (HESN) stable relationship HIV-infected partners.We recruited 27 serodiscordant couples. HESN were classified according exposure into very low/low and moderate/high risk. Plasma from partners tested for neutralizing capacity the recognition cell-surface expressed...
Objectives The objective of this study was to seek correlates immune protection in HIV infection. We sought elucidate the association between presence human leucocyte antigen ( HLA ) alleles, as well killer immunoglobulin receptor KIR genotypes, and susceptibility infection a Spanish cohort ‐exposed seronegative HESN individuals. Methods A total 152 individuals were evaluated: 29 stable heterosexual relationships with an ‐infected partner admitting high‐risk sexual intercourse for at least...
Fase previa de una investigación acción realizada en el aula educación universitaria Deporte, la Institución Universitaria Escuela Nacional del Deporte Cali, Valle Cauca, para diagnosticar situaciones predominantes clase tradicional, que anteceden a innovación pedagógica, mediada por técnica enseñanza Flipped Classroom (FC), procurando mejor comprensión y reconocimiento actualidad trabajo durante proceso aprendizaje (E-A). La muestra intencional, carácter no probabilístico, conformada 142...
Abstract Double negative (DN) T cells are CD3 + , CD4 − CD8 with either T‐cell receptors (TCR) αβ or TCR γδ whose importance on protection against HIV infection is unknown. Since HIV‐exposed seronegative individuals correspond to an ideal group in whom correlates of expected, the role these was studied 13 HIV‐serodiscordant couples a stable relationship and reporting unprotected sexual intercourses. HIV‐specific immune responses mediated by DN T‐cells were evaluated measuring intracellular...
Se estudia la calidad de las causas muerte certificadas en el Boletín Estadístico Defunción España 1985, evaluando número defunciones que causa aparecida citado estaba mal definida o poco especificada. Para ello, estas se han dividido dos grupos: grupo definidas (GMD1) consta todas del XVI Clasificación Internacional Enfermedades, y resto especificadas no incluidas (GMD2). El 3,1% 1985 están GMD1 17,5% GMD2. Los grupos edad con un mayor porcentaje por son menos año (4,7%) mayores 75 (4,2%)....
Early steps of HIV infection are mediated by the binding envelope to mucosal receptors as α4β7 and C-type lectins DC-SIGN langerin. Previously Env-specific B-cell responses have been reported in highly exposed seronegative individuals (HESN).Here, we studied gp120-specific antibodies ability block interaction with α4β7, and/or langerinin HESN. New cell-based assays were developed analyze whether that can alter gp120 langerin induced A blocking score (MBS) was defined based on interfere...
Non-cystic fibrosis bronchiectasis is a complex medical condition with multiple etiologies, characterized by chronic productive cough and radiologic evidence of airway lumen dilation wall thickening. Associated exacerbations declining lung function contribute to increasing disability mortality. There are no data about the prevalence non-cystic etiologies in Colombian population. To investigate etiology clinical characteristics adults evaluated southwest Colombia. We conducted...
