Time-Resolved Synchrotron-Based Investigation of Reactive Pore Evolution in Sandstone for CO 2 Storage

Abstract Understanding mineral dissolution in heterogeneous porous media is critical for predicting the evolution of subsurface systems during geological CO2 storage. Here, we integrate time-resolved synchrotron techniques, 4D X-ray microtomography (μ-CT), X-ray fluorescence (TR-...

Schizophrenia research in 2026: report from the annual meeting of the Schizophrenia International Research Society

Abstract SIRS 2026, held under the theme “Schizophrenia Research in the Era of Artificial Intelligence,” brought together researchers, clinicians, and persons with lived experience to take stock of a field whose tools for measuring, predicting, and intervening in psychosis have e...

Associations of food processing and dietary risk factors with colorectal cancer incidence in the NIH-AARP Diet and Health Study: A cohort study

Background Ultra-processed foods (UPF) account for >50% of energy intake by US adults. UPF intake can include dietary components linked to lower colorectal cancer (CRC) risk, such as whole grain and dairy products, and others linked to higher CRC risk, such as processed meats, po...

Task force of the Brazilian Society of Otology and the Brazilian Academy of Neurotology: Menière’s Disease

Objective To critically review the available evidence on the pathophysiology and diagnosis of Menière’s disease and to provide consensus-based recommendations developed by a task force of the Brazilian Society of Otology and the Brazilian Academy of Neurotology. Methods A task fo...

Teaching health advocacy in primary health care: a qualitative study with professors from the University of São Paulo medical school

Contemporary medical education continues to face challenges in integrating social determinants of health and social responsibility into the training of future physicians. In Brazil, the National Curriculum Guidelines for medical education emphasize comprehensive care across all l...

Wavelength dependent effects of red and infrared photobiomodulation on neuropathic pain, skeletal muscle integrity, and mitochondrial respiration

Abstract Neuropathic pain is a chronic and difficult to treat condition affecting up to 10% of the population, significantly impairing quality of life and representing a public health concern. Photobiomodulation (PBMT) has emerged as a promising therapeutic approach, as photons c...

One-step production and physicochemical characterization of biodiesel using rubber seed oil blends

Abstract The seeds of Hevea brasiliensis (HB) stand out as a promising feedstock for biodiesel production owing to their high oil content. However, its elevated acid value poses a challenge, requiring pre-treatment steps before transesterification. Given this scenario, the presen...

Why do some Latin American countries flourish despite material constraints? Insights from the Global Flourishing Study

The Latin American region faces ongoing challenges related to disease burden, healthcare inequalities, and constraints on quality of life.1 Despite these structural barriers, countries in this region often score higher on subjective indicators of well-being (e.g., life evaluation...

Challenges in Monitoring Extreme Environmental Conditions in the Brazilian Amazon: Impacts on Navigation Safety

Inland navigation in the Brazilian Amazon plays an important role in transportation of personnel and cargo, including the development of activities of social relevance. However, the occurrence of extreme environmental conditions can pose risks to the safety of operating vessels....

The Spectral Energy Distribution of QR And : Preliminary Analysis

ABSTRACT We present a preliminary multiwavelength spectral energy distribution (SED) analysis of the Galactic supersoft X‐ray source QR Andromedae (QR And). The longer‐wavelength portion, spanning from the ultraviolet to the infrared, was built from compiled archival and catalogu...

Hormonal imbalances and neuroendocrine influences in temporomandibular disorders: A scoping review of the evidence

Background Temporomandibular disorders (TMD) display a marked female predominance and fluctuate across reproductive stages, suggesting hormonal and neuroendocrine contributions.Objectives To map the evidence on hormonal imbalances and neuroendocrine influences in TMD across six d...

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...

Trends and Thematic Clusters in Studies on Biosensors for Groundwater Quality

Groundwater plays an important role in food production. However, it faces environmental pressures from various factors, and the presence of contaminants in these waters—whether emerging or traditional—is a growing cause for concern. Nevertheless, there are few reviews available t...

Weaving a theory of change: mapping the pathway for Peer Support implementation in community mental health services in Brazil through co-produced participatory workshops

Abstract Background Peer Support (PS) has gained increasing recognition as a recovery-oriented practice in mental health services by valuing the experiential knowledge of individuals with lived experience of psychological distress. While PS has been widely implemented in high-inc...

Recurrence lacunarity of spatial data

Abstract Quantifying the structure and heterogeneity of complex spatial patterns remains a key challenge in spatial data analysis. Recurrence plots (RPs) offer a powerful method for visualizing the recurrent spatial patterns in such data. To quantify the structure of spatial recu...

Assessing mangrove sensitivity to thermal variations through a satellite-based analysis on the southern São Paulo coast, Brazil

Abstract Mangroves near subtropical range limits may benefit from fewer cold constraints, yet warmer conditions can also increase atmospheric water demand. These competing possibilities were examined in the Cananéia-Iguape Coastal System, southeastern Brazil, by combining ERA5 2...

Generalized Thermodynamics and Phase Transitions of Vaidya-adS Black Holes

This work investigates the thermodynamics of non-stationary anti-de Sitter (adS) black holes and their gauge-gravity duals. To model a non-equilibrium process, we employ a time-dependent Vaidya-adS metric to describe the collapse of a null fluid and the subsequent thermalization...

Allogeneic Hematopoietic Cell Transplantation for Pediatric Unstable Hemoglobinopathies: An Aggregated Cohort with Long-Term Follow-Up from a Brazilian Center

Background/Objectives: Severe unstable hemoglobinopathies may cause transfusion dependence from early childhood, and allogeneic hematopoietic cell transplantation (allo-HCT) is the only established curative option. Pediatric experience with allo-HCT for unstable hemoglobinopathie...
