Volcanic textures control the mechanical behaviour of Mesoamerican obsidians
Abstract Obsidian—natural volcanic glass—was exploited for millennia and played a central role in the technological and socio-economic development of pre-Hispanic societies across Mesoamerica. The selection of obsidian from specific deposits has been linked to differences in visu...

Background Cardiovascular diseases (CVD) are the leading cause of death worldwide, and their epidemiology is correlated with genetic predisposition and exposure to risk. Brazil is a developing country with a vast territory, which leads to structural inequalities. We aimed to comp...

Identifying Cardiac Autoantibody Biomarkers that Predict the Severity of Chagas Cardiomyopathy
Chagas cardiomyopathy (ChCM) affects up to 30% of patients with chronic Chagas disease and lacks reliable biomarkers for severity and conduction abnormalities. We profiled cardiac autoantibodies using 2-dimensional gel electrophoresis and mass spectrometry, followed by enzyme-lin...

A novel chlorovirus was isolated from a freshwater sample collected from a Brazilian urban lake. Members of the family Phycodnaviridae, the chloroviruses have large linear dsDNA genomes (285–410 kbp) that encode hundreds of proteins and tRNAs. Despite their ecological and evoluti...

Counterion-Mediated Humidity Modulation of Electronic Transport in Pristine MWCNT/TOCNF Composites
Abstract Humidity-driven electrical responses in carbon-cellulose composites are commonly attributed to matrix swelling. However, in TEMPO-oxidized nanocellulose (TOCNF), water uptake also releases Na+ counterions from carboxylate residues, enabling interfacial polarization via i...

Lived experience in deliberative forums: a matter of design
Deliberative forums, including randomly selected minipublics, are increasingly expected to incorporate lived experience into democratic decision-making. Yet, without careful design, they risk marginalizing, extracting, or essentializing these experiences. This paper argues that s...

Single-Port Versus Multiport Robotic Colorectal Surgery: A Systematic Review and Meta-Analysis
Background: Single-port (SP) robotic surgery has emerged as a reduced-access alternative to conventional multiport (MP) robotic colorectal surgery. However, its comparative perioperative benefits remain uncertain. This systematic review and meta-analysis compared outcomes between...

Detection of Chagas Disease from the ECG: The George B. Moody PhysioNet Challenge 2025
Abstract Objective: Chagas disease is a parasitic infection that is endemic to Latin America and primarily transmitted by insects. When untreated, Chagas disease can cause cardiomyopathy. Serological testing capacities for Chagas disease are limited, but Chagas cardiomyopathy oft...
