Chagas disease (CD), a parasitic infection, may have ocular repercussions in its cardiologic form, since a history of heart disease of other etiologies already has been established as a risk factor for neuropathies and maculopathies. The aim of the present study was to investigate preclinical structural and vascular optic nerve head (ONH) and macular parameters in patients with chronic CD. Nineteen patients with CD and 19 healthy subjects were evaluated with optical coherence tomography, optical coherence tomography angiography, and Laguna ONhE® software.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries.

Chemometrics and digital image colorimetry approaches applied to paper-based analytical devices: A review.

Anal Chim Acta

February 2025

Laboratório de Sensores Químicos Portáteis, Universidade Estadual de Campinas (UNICAMP), Campinas, SP, 13083-861, Brazil. Electronic address:

Colorimetric paper-based analytical devices (CPADs) are cost-efficient and high-throughput technologies that use readily available materials for point-of-need (PON) applications by leveraging color changes in response to target analytes. However, the complexity of samples can limit the precision and accuracy of CPAD applications. Therefore, CPADs have been combined with chemometric approaches to enhance analytical performance and provide simple solutions to complex systems.

Tuning Aromaticity, Stability and Radicaloid Character of Periacenes by Chemical BN Doping.

J Comput Chem

January 2025

Departamento de Química, Instituto Tecnológico de Aeronáutica, São José dos Campos, Brazil.

In this work, the stability, aromaticity and radical character of pristine and eleven BN-doped armchair 5 and zigzag 5, 6, and 7 periacenes, were chosen for studying the effect of different doping schemes to stabilize the periacene, and to direct the open-shell density into specific regions of the PAH sheets. Ab initio multireference methods and different DFT functionals were used to analyze the singlet triplet (ST) energy. Moreover, a range of descriptors were used to characterize the open-shell character and aromaticity of the different doped structures.

Carbapenemase-producing Enterobacterales are a growing concern in public health. In order to rapidly determine the antimicrobial profile, the MALDI Biotyper - antibiotic susceptibility test rapid assay (MBT-ASTRA) was developed, based on the relative growth of bacteria in the presence of antibiotics. In this study, we added carbapenemase enzymatic inhibitors to the MBT-ASTRA and developed an adapted method named MALDI Biotyper - Phenotypic Identification Test Rapid Assay (MBT-PITRA) in order to perform a rapid and cost-effective phenotypic test to detect Klebsiella pneumoniae carbapenemase (KPC) and New Delhi metallo-beta-lactamase (NDM), including co-producers, in Enterobacterales.

The impact of obesity on mitochondrial dysfunction during pregnancy.

Mol Cell Endocrinol

January 2025

Laboratory of Neurobiology of Inflammatory and Metabolic Processes, Postgraduate Program in Health Sciences, University of Southern Santa Catarina, Tubarão, Santa Catarina, Brazil.

Mitochondria play a central role in nutrient metabolism, besides being responsible for the production of adenosine triphosphate (ATP), the main source of cellular energy. However, the ATP production process is associated with the generation of reactive oxygen species (ROS), which excessive accumulation can cause mitochondrial dysfunction. This dysfunction, in turn, causes the accumulation of fatty acids in the adipose tissue, triggering a local inflammatory process that can evolve into systemic inflammation.

The rising production and improper disposal of titanium dioxide nanoparticles (TiO NPs) into aquatic systems present considerable environmental challenges, especially when these particles interact with other contaminants such as cadmium (Cd). Thus, the current study aimed to evaluate the potential toxic effects on the gills, chondrocranium, body growth, and mortality of Aquarana catesbeiana tadpoles. The tadpoles were exposed to environmentally relevant concentrations of TiO NPs (10 µg L), and CdCl (10 µg L), both individually and in combination, for 30 days (chronic exposure), along with a control group.

Leaving the incubation chamber: Cellular and physiological challenges of the juvenile stage of the sea anemone Anthopleura hermaphroditica (Carlgren, 1899) to cope with fluctuating environmental stressors in the Quempillén estuary, southern Chile.

January 2025

Instituto de Ciencias Marinas y Limnológicas, Facultad de Ciencias, Universidad Austral de Chile, Valdivia, Chile; Laboratorio Costero de Recursos Acuáticos de Calfuco, Facultad de Ciencias, Universidad Austral de Chile, Valdivia, Chile.

Environmental stress on early life stages has severe consequences for individual performance and population dynamics. The internal incubation process of the symbiotic intertidal anemone Anthopleura hermaphroditica ends when the juveniles leave the gastrovascular cavity of the adult, at which moment they are exposed to a highly stressful environment due to tidal changes and environmental radiation in the Quempillén estuary. To determine the cellular and physiological tolerance capabilities of juvenile anemones to changes in salinity and environmental radiation resulting from the abandonment of the gastrovascular cavity, an experiment with an orthogonal design was performed on individuals exposed to four levels of salinity (30.

Waterlogging is a significant stressor for crops, particularly in lowland regions where soil conditions exacerbate the problem. Waterlogged roots experience hypoxia, disrupting oxidative phosphorylation and triggering metabolic reorganization to sustain energy production. Here, we investigated the metabolic aspects that differentiate two soybean sister lines contrasting for waterlogging tolerance.
