Springs are essential for water resources; therefore, it was imperative to investigate the occurrence of inorganic and emerging organic contaminants in water and sediment samples collected from three spring areas located in the Dourados River Basin (DRB), Mato Grosso do Sul (MS) State, under direct influence of soybean monoculture. Water and sediment samples were collected monthly from October (2021) to March (2022), throughout the soybean production period. The quantification of inorganic elements (Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Pb, and Zn) was conducted using inductively coupled plasma optical emission spectrometry (ICP-OES), while the quantification of organic emerging contaminants (ECs) was performed using liquid chromatography coupled to mass spectrometry (LC-MS/MS).

In this study, the potential of three green manure species, , , and , was assessed in terms of their ability to reduce soil ecotoxicity by examining the uptake of 2,4-D and fipronil, both individually and in a mixture. The experiments were performed with 20 µg kg of each pesticide, lasting 30 days, and the contaminants were quantified in soil and plant biomass (shoots and roots).

Despite the recent reports, integrated information related to the measurements and effects of NSAIDs on Brazilian water ecosystems is still limited, given the importance of Brazilian aquatic biodiversity. Thus, to fill these gaps, after a close literature search using scientific databases, this review aims to summarize the main scientific efforts concerning the occurrence of NSAIDs in Brazilian aquatic environments, the multiple physiological effects on native species, and the different protocols used in the research laboratories.

This study analyzed the relationship between green space, measured via the Normalized Difference Vegetation Index (NDVI), and diabetes-related hospitalizations from 2008 to 2018. Using quasi-Poisson regression models, we assessed hospitalization data by sex and age group, incorporating air pollution, weather, and socioeconomic factors as covariates.

Background: Heart failure is a prevalent condition ideally managed through collaboration between health care sectors. Telehealth between cardiologists and primary care physicians is a strategy to improve the quality of care for patients with heart failure. Still, the effectiveness of this approach on patient-relevant outcomes needs to be determined.

In the production of this instruction manual, a broad literature review was conducted for the identification and discussion of topics to be treated. The content and appearance validity were conducted according to the Delphi technique and to focus groups, respectively, with evaluators who were nutritionists and practitioners, from different regions of Brazil.

Therefore, the use of large amounts of pesticides directly impacts all environmental compartments, including rainwater. We analyzed 14 pesticides and 5 degradation products in rainwater from three cities in the State of São Paulo, southeastern Brazil, with distinct land uses.

Herbicides are the main class of pesticides applied in crops and are capable of polluting the surrounding freshwater system; thus, understanding their impact on non-target species, whose mechanism of action is not described, helps to elucidate the real risks of these pollutants to the environment. 2,4-dichlorophenoxyacetic acid (2,4-D) is frequently detected in water and, due to its persistence, poses a risk to wildlife. In this way, the present work aimed to describe the implication of exposure to concentrations of 2,4-D already reported in aquatic environments in several physiological mechanisms of C.

Among the most promising biopolymers is poly(lactic acid) (PLA), with a reported high degree of biocompatibility and biodegradability. In this work, PLA NPs were synthesized according to a controlled gelation process using a combination of single-emulsion and nanoprecipitation methods.

In plants, this phenomenon is widespread, but its extent varies significantly among species and organellar genomes. Among land plants, the heterosporous lycophytes (i.

Diclofenac (DCF) and ibuprofen (IBU) are pharmaceutical compounds frequently detected in aquatic compartments worldwide. Several hazard effects including developmental abnormalities and redox balance impairment have been elucidated in aquatic species, but multiple endocrine evaluations are scarce. Therefore, the present study aimed to assess the disruptive physiological effects and toxicity of DCF and IBU isolated and combined, using females of the native freshwater teleost Astyanax lacustris.

To date, retinal eye diseases, such as diabetic retinopathy, age-related macular degeneration, retinitis pigmentosa, glaucoma, and others, affect nearly 170 million people worldwide, resulting in vision loss and blindness. To tackle retinal disorders, the developing retina has been explored as a versatile model to study intercellular signaling, as it presents a broad neurochemical repertoire that has been approached in the last decades in terms of signaling and diseases.

The use in rAAV of ubiquitous promoters derived from viral sequences such as CMV/CBA (chicken β-actin promoter with cytomegalovirus enhancer) can lead to unwanted side effects such as pro-inflammatory immune responses and retinal cytotoxicity, thus reducing therapy efficacy. Thus, an advance in gene therapy is the availability of small promoters, that potentiate and direct gene expression to the cell type of interest, with higher safety and efficacy.

Recent data reveals an annual production of approximately 14 million tons of plastic waste, not accounting for the surge in the usage of plastic masks and related materials due to the COVID-19 pandemic. However, what remains largely unreported is that over half of post-consumer plastic packaging in Brazil is managed without any monitoring, and it remains unclear how this will contribute to the occurrence of plastic waste and microplastics in Brazilian freshwaters.

Heart failure is a prevalent condition and a frequent cause of hospital readmissions and poor quality of life. Teleconsultation support from cardiologists to primary care physicians managing patients with heart failure may improve care, but the effect on patient-relevant outcomes is unclear. We aim to evaluate whether collaboration through a novel teleconsultation platform in the Brazilian Heart Insufficiency with Telemedicine (BRAHIT) project, tested on a previous feasibility study, can improve patient-relevant outcomes.
