Prenatal syphilis and adverse pregnancy outcomes in women with HIV receiving ART in Brazil: a population-based study.

Background: We aimed to examine factors associated with prenatal syphilis, including prenatal care, and pregnancy outcomes of pregnant women with HIV in Brazil.

Methods: Retrospective data were gathered from a national cohort of Brazilian women with HIV on antiretroviral therapy who became pregnant between January 2015 and May 2018. Prenatal syphilis was defined by clinical diagnoses with treatment or any positive syphilis laboratory result between 30 days before conception and pregnancy conclusion.

I-motif formation in the promoter region of the B-MYB proto-oncogene.

Understanding the mechanisms of carcinogenesis is essential to combat cancer. The search for alternative targets for anticancer therapy has gained interest, particularly when focused on upstream pathways. This strategy is particularly relevant when the encoded target proteins are known - or believed - to be "undruggable", as has been reported for the B-MYB oncogene.

TBK1 Targeting Is Identified as a Therapeutic Strategy to Enhance CAR T-Cell Efficacy Using Patient-Derived Organotypic Tumor Spheroids.

Novel therapeutic strategies are needed to improve the efficacy of chimeric antigen receptor (CAR) T cells as a treatment of solid tumors. Multiple tumor microenvironmental factors are thought to contribute to resistance to CAR T-cell therapy in solid tumors, and appropriate model systems to identify and examine these factors using clinically relevant biospecimens are limited. In this study, we examined the activity of B7-H3-directed CAR T cells (B7-H3.

Genetic characterization of paternal lineages by Y-STR in three sample populations in Northeastern Brazil.

Genetic markers of the Y chromosome are powerful tools for investigating paternal ancestry and are widely used in population and forensic genetics. However, in order to obtain statistics with a higher degree of certainty using these markers, it is necessary to obtain haplotypic frequencies from a representative database, as well as knowing the diversity and structure of the population. The aim of this study was to investigate the genetic diversity of a sample of 1114 unrelated men from three states in the Northeast of Brazil: Paraíba, Pernambuco and Ceará, through the analysis of 23 Y-STRs and to contribute to the expansion of the Brazilian database on these markers.
