Objective: HIV-infected individuals with incomplete CD4+ T-cell recovery upon combination antiretroviral therapy (cART) display high levels of immune activation and microbial translocation. However, whether a link exists between gut damage poor immunological reconstitution remains unknown. Design: Cross-sectional study the gastrointestinal tract in late cART-treated individuals: 15 nonresponders (CD4+ <350 cells/μl and/or delta change from baseline <30%); full responders >350 >30%). Methods:...

Background: We explored the long-term effects of cART on markers gut damage, microbial translocation, and paired gut/blood microbiota composition, with a focus role exerted by different drug classes. Methods: enrolled 41 naïve HIV-infected subjects, undergoing blood fecal sampling prior to (T0) after 12 (T12) 24 (T24) months therapy. Fifteen HIV-uninfected individuals were as controls. analyzed: (i) T-cell homeostasis (flow cytometry); (ii) translocation (sCD14, EndoCab, 16S rDNA); (iii)...

Objective: Analysis of functionally defined T-cell differentiation in HIV-infected patients with low CD4+ on virologically suppressive HAART is crucial to design clinically efficacious treatments. Methods: We cross-sectionally investigated the maturation (CD45RA/CCR7, CD7) and function [antigen-specific enzyme-linked immunosorbent spot assay (ELISPOT), interleukin-2 (IL-2)/interferon-γ-producing cells] CD8+ T cells 34 immunological nonresponders (INRs): cell count less than or equal 200...

Abstract Thickening of the gallbladder wall is often associated with acute or chronic cholecystitis, adenomyomatosis and carcinoma seen in context liver systemic diseases (acute hepatitis, cirrhosis, sepsis). Here we present a case 61 y.o. man focal thickening wall, whom all imaging techniques were inconclusive. Pathological examination resected revealed acute-on-chronic cholecystitis. We describe cholecystitis absence classic clinical findings (Murphy’s sign, fever, gallstones, hydrops,...

Abstract We show that the hyper‐Kähler varieties of OG10‐type constructed by Laza–Saccà–Voisin (LSV) verify Lefschetz standard conjecture. This is an application a more general result, stating certain Lagrangian fibrations this The main technical assumption result fibration satisfies hypotheses Ngô's support theorem. Verifying LSV tenfolds do satisfy those independent interest. Another point interest paper definition and study conjecture in relative setting, its relation to classical absolute case.

We investigated the effect of LPS in vitro stimulation on T-cell activation HIV-infected patients with different CD4+ recovery HAART. PBMCs from 30 HIV-positive, HAART-treated, aviremic individuals reconstitution (Low Responders: &lt; 350/μL; Intermediate 350–599/μL; High ≥ 600/μL) were cultured and proportion HLA-DR/CD38- Ki67-expressing CD4+/CD8+ T-cells was measured (flow cytometry). Upon stimulation, significantly higher CD8+HLA-DR+ cells shown LR IR versus HIV-negative controls. While...

The association between chronic autoimmune thyroiditis (CAT) and differentiated thyroid cancer (DTC) remains controversial. incidence of DTC increases when screening procedures are implemented, as typically occurs in CAT patients being routinely submitted to ultrasound (US). aim this study was longitudinally evaluate the long-term development with CAT.A retrospective longitudinal cohort designed. For study, 510 a 10-year follow-up were enrolled. Patients divided two groups according presence...

We prove that any commutative group scheme over an arbitrary base of finite type a field with connected fibers and admitting relatively ample line bundle is polarizable in the sense Ng\^o. This extends applicability Ng\^o's support theorem to new cases, for example Lagrangian fibrations integral has consequences construction algebraic classes. Comment: comments welcome

HIV infection causes the progressive depletion of CD4+ T-lymphocytes and profound modifications T-cell homeostasis, which persist despite virologically-suppressive treatment have been linked to a worse clinical outcome. Enduring alterations gastrointestinal tract may represent underlying pathogenic mechanisms these phenomena. Twenty-six HIV-infected subjects were assessed over 12-month period following introduction antiretroviral therapy. 18 uninfected individuals enrolled as controls....
