In 2006, a PCR method was introduced to subtype by Sanger sequencing of an ≈610 bp amplicon of the 18S rRNA gene. This method, known as barcoding-PCR, has become widespread, although the primer pair used can amplify non- sequences, which can result in false positives. Barcoding-PCR is most effective with DNA extracted from cultures, limiting its sensitivity when used directly with stool samples.

Objective: To analyze the impact of the Covid-19 pandemic on the occurrence of work accidents involving biological materials (ATBio) and to assess changes in the epidemiological profile of these cases.

Methods: An ecological time-series study with a cross-sectional component was conducted using ATBio notifications in Brazil from 2015 to 2022 in the Information System for Notifiable Diseases (Sinan). Interrupted time-series analyses were performed using Prais-Winsten regression models, temporal predictions, and multiple logistic regression to identify changes in the profile between the pandemic and pre-pandemic periods.

Article Synopsis
  • High-risk non-muscle-invasive bladder cancer (NMIBC) has high rates of recurrence and progression, and there's a need to better understand the tumor microenvironment (TME) for identifying treatment outcome biomarkers.
  • Researchers analyzed TME components and PD-L1 expression in 73 NMIBC patients, finding significant changes in tissue compared to non-tumoral samples, including increased cancer-associated fibroblasts and altered immune cell distributions.
  • The study identified myofibroblasts (myoCAFs) and M2-like macrophages as particularly significant in high-grade NMIBC, with myoCAFs correlating to higher rates of cancer progression and recurrence, providing insights for future prognostic markers.

The study of human body shape using classical anthropometric techniques is often problematic due to several error sources. Instead, 3D models and representations provide more accurate registrations, which are stable across acquisitions, and enable more precise, systematic, and fast measuring capabilities. Thus, the same person can be scanned several times and precise differential measurements can be established in an accurate manner.

The results of a survey of vascular plant species along two elevational gradients in the high Andes of central Chile (33°S) are reported. Vascular plant species were recorded in 12 and 15 plots of 1600 m set up to be permanent, distributed at intervals of 100 m elevation along two elevational gradients, one in the La Parva (2500-3600 m a.s.
