Single-nucleotide polymorphisms in genes associated with the vitamin D pathway related to clinical and therapeutic outcomes of American tegumentary leishmaniasis.

Background: The vitamin D pathway contributes to the microbicidal activity of macrophages against infection. In addition to induction of this pathway, interferon-gamma (IFNγ), interleukin (IL)-15, and IL32γ are part of a network of pro-inflammatory cytokines. The aim of this study was to evaluate single-nucleotide polymorphisms (SNPs) in the components of the vitamin D pathway and associated cytokine genes that could be related to resistance or susceptibility to American tegumentary leishmaniasis (ATL).

Development and validation of a search strategy and an automated classifier for retrieving temporomandibular disorders studies.

The objective was to develop and evaluate a comprehensive search strategy (SS) and automated classifier (AC) for retrieving temporomandibular disorders (TMD) research articles. An initial version of SS and AC was created by compiling terms from various sources, including previous systematic reviews (SRs) and consulting with TMD specialists. Performance was assessed using the relative recall (RR) method against a sample of all the primary studies (PS) included in 100 TMD-related SRs, with RR calculated for both SS and AC based on their ability to capture/classify TMD PSs.

The role of the complement system in Shiga toxin-associated hemolytic uremic syndrome.

Background: This research explores complement activation products involvement and risk and protective polymorphisms in the complement alternative pathway genes in Shiga toxin-associated hemolytic uremic syndrome (STEC-HUS) pathogenesis.

Methods: We analyzed the levels of complement activation products, C3a, C5a and soluble C5b-9 (sC5b-9) and plasma concentrations of Factor H (FH) and FH-related protein 1 (FHR-1) in 44 patients with STEC-HUS, 12 children with STEC-positive diarrhea (STEC-D), and 72 healthy controls (HC). STEC-HUS cases were classified as "severe" or "non-severe".

Exploring the Antimycobacterial Potential of Podocarpusflavone A from : In Vitro and In Vivo Insights.

: Tuberculosis (TB) is one of the leading infectious causes of death worldwide, highlighting the importance of identifying new anti-TB agents. In previous research, our team identified antimycobacterial activity in leaf extract; therefore, this study aims to conduct further exploration of its potential. : Classical chromatography was applied for fractionation and spectrometric techniques were utilized for chemical characterization.

Effect of in vitro exposure of first-line antiretrovirals on healthy human spermatozoa on kinematics and motility.

Purpose: Contemporary antiretroviral (ARV) medications are used by millions of men for HIV treatment worldwide. Limited data exist on their direct effect on sperm motility. This pilot study hypothesizes that in vitro exposure to ARVs will reduce sperm kinematic and motility parameter values.
