Sci Rep

January 2025

Laboratory of Ichthyology and Fisheries Statistics, Grupo de Pesquisas em Recursos Pesqueiros e Limnologia (GERPEL), Western Paraná State University (UNIOESTE), Campus Toledo, Rua Guaíra, Toledo, 3141, 85903-220, Paraná, Brazil.

Various fishing activities are common economic practices in large hydroelectric reservoirs, such as Itaipu. Consequently, the Itaipu company has monitored artisanal commercial fishing since the formation of its reservoir. In this study, we used long-term monitoring data to evaluate the sustainability of this fishing activity in the Itaipu Reservoir, one of the largest reservoirs in the Neotropical region.

Background And Aim: Endoscopic biliary drainage with placement of a self-expanding metal stent (SEMS) is the preferred palliative treatment of malignant biliary obstruction. Recent advances in the treatment have prolonged survival, thus, increasing the chance of recurrent biliary obstruction (RBO) after SEMS placement. The aim of this study was to compare different endoscopic approaches in patients with a SEMS and RBO, regarding clinical success and time to RBO.

Chronic pain and depression exhibit a high comorbidity, are challenging to manage, and their pathophysiology mechanisms are intricated and closely related to the up-regulation of pro-inflammatory response and oxidative stress. Chronic pain and depression often coexist and present significant management challenges. Their underlying pathophysiological mechanisms are complex and closely linked to the up-regulation of pro-inflammatory responses and oxidative stress.

January 2025

Laboratório de Plasmas e Processos - LPP, Instituto Tecnológico de Aeronáutica - ITA/DCTA, São José dos Campos, SP, Brazil.

This study aimed to investigate the thermal plasma treatment of sewage sludge as an alternative waste management solution. Samples were collected from a sewage treatment facility in São Paulo, Brazil, and subjected to thermal treatments in a furnace at temperatures of 400, 600, 800, and 900 °C to assess moisture content, mass loss, and ash composition. Subsequently, the samples were processed in a thermal plasma reactor operating at an average power of 30 kW.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants, detected even in remote regions such as the Antarctic, Arctic, and Tibetan Plateau. Thus, understanding their biodegradation processes at low temperatures is crucial. Therefore, the potential of fungal strains from the Antarctic to biodegrade PAHs was explored.

Neglecting proper skin care and repeated exposure to ultraviolet (UV) radiation can have serious consequences, including skin burns, photoaging and even the development of skin cancer. UV radiation-induced damage is mediated by highly unstable and reactive molecules, named reactive oxygen species (ROS). To counteract ROS, the skin has an endogenous antioxidant system.

Background: Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition emerging in early childhood, characterized by core features such as sociocommunicative deficits and repetitive, rigid behaviors, interests, and activities. In addition to these, disruptive behaviors (DB), including aggression, self-injury, and severe tantrums, are frequently observed in pediatric patients with ASD. The atypical antipsychotics risperidone and aripiprazole, currently the only Food and Drug Administration-approved treatments for severe DB in patients with ASD, often encounter therapeutic failure or intolerance.

Purpose: Prior noncontemporary studies showed that oral cyclophosphamide is an active treatment of metastatic castration-resistant prostate cancer (mCRPC). However, cyclophosphamide is currently underutilized in routine clinical practice given the lack of survival benefit and the emergence of more effective treatments.

Methods: We retrospectively reviewed our institutional database to identify patients with mCRPC treated with cyclophosphamide.

Inequalities and Inclusion in Genomics Applied to Healthcare: A Latin American Perspective.

Annu Rev Genomics Hum Genet

January 2025

1Department of Medical Genetics and Genomic Medicine, School of Medical Sciences, University of Campinas, Campinas, Brazil;

Integrating genomics into healthcare within the precision medicine (PM) framework poses distinct challenges in resource-limited regions like Latin America and the Caribbean (LAC). These challenges arise partly from the lack of PM models tailored for low- and middle-income countries. To address this, healthcare authorities in LAC should adopt predictive models to estimate costs and infrastructure needed for PM programs.

CuO/CeO and CuO/CeO-LaO catalysts, synthesized with varying CeO and LaO molar ratios (1:1, 1:2, and 2:1), were prepared via the hydrothermal method and tested in the water-gas shift reaction (150-350 °C). LaO addition altered structural properties, reducing surface area and copper dispersion. XANES and in situ XRD confirmed metallic Cu species during reduction and reaction.

January 2025

Department of Chemical and Materials Engineering, Pontifical Catholic University of Rio de Janeiro, 225, Marquês de São Vicente Street, Gávea, Rio de Janeiro, RJ 22451-900, Brazil.

Machine learning approaches often involve evaluating a wide range of models due to various available architectures. This standard strategy can lead to a lack of depth in exploring established methods. In this study, we concentrated our efforts on a single deep learning architecture type to assess whether a focused approach could enhance performance in fault diagnosis.

Importance: Triple-negative breast cancer is an aggressive subtype with a high incidence in young patients, a high incidence in non-Hispanic Black women, and a high risk of progression to metastatic cancer, a devastating sequela with a 12- to 18-month life expectancy. Until recently, one strategy for treating early-stage triple-negative breast cancer was chemotherapy after surgery. However, it was not known whether the addition of immune therapy to postsurgery chemotherapy would be beneficial.

Departamento de Ciências Exatas, Universidade Estadual Paulista (UNESP), Faculdade de Ciências Agrárias e Veterinárias, Jaboticabal, Brazil.

Natural and artificial selection in domesticated animals can cause specific changes in genomic regions known as selection signatures. Our study used the integrated haplotype score (iHS) and Tajima's D tests within non-overlapping windows of 100 kb to identify selection signatures, in addition to genetic diversity and linkage disequilibrium estimates in 9498 sheep from breeds in Ireland (Belclare, Charollais, Suffolk, Texel, and Vendeen). The mean observed and expected heterozygosity for all the sheep breeds were 0.
