Distribution and role of peripheral arterial chemoreceptors in cardio-respiratory control of the south american rattlesnake (Crotalus durissus).

Peripheral arterial chemoreceptors monitor the levels of arterial blood gases and adjust ventilation and perfusion to meet metabolic demands. These chemoreceptors are present in all vertebrates studied to date but have not been described fully in reptiles other than turtles. The goals of this study were to 1) identify functional chemosensory areas in the South American rattlesnake (Crotalus durissus) 2) determine the neurochemical content of putative chemosensory cells in these areas and 3) determine the role each area plays in ventilatory and cardiovascular control.

Early maternal undernutrition induces sex-related metabolic changes in adult offspring.

Nutritional status during the developmental periods leads to predisposition to several diseases and comorbidities, highlighting metabolic and reproductive changes throughout adult life, and in the next generations. One of the experimental models used to induce undernutrition is litter size expansion, which decreases the availability of breast milk to pups and delays development. This work evaluated the effects of maternal undernutrition induced by litter size expansion, a maternal undernutrition preconception model, on the metabolic and reproductive alterations of the offspring.

Effects of the Interaction of Salinity and Rare Earth Elements on the Health of : The Case of Praseodymium and Europium.

The growing use of products containing rare earth elements (REEs) may lead to higher environmental emissions of these elements, which can potentially enter aquatic systems. Praseodymium (Pr) and europium (Eu) are widely used REEs with various applications. However, their ecotoxicological impacts remain largely unexplored, with poorly understood risks to wildlife.

Salinity modulation of neodymium and dysprosium toxicity in mussels: A comprehensive analysis of adult and sperm responses.

Neodymium (Nd) and dysprosium (Dy) are among the most commonly used rare earth elements (REEs) worldwide, leading to their increased concentrations in aquatic environments, with potential impacts on organisms. Additionally, organisms are also subjected to environmental stressors, such as salinity shifts, which can not only directly impact their health but also modulate the impacts of contaminants. Therefore, this study aimed to evaluate the effects of Nd and Dy on adult mussels and sperm of the species Mytilus galloprovincialis after 28 days and 30 min of exposure, respectively.

Instruments used by physiotherapists to assess functional capacity in hospitalized patients with COVID-19: An online survey.

Background: Assessing functional capacity in hospitalized patients with COVID-19 may have been neglected due to a great demand for resources at the height of pandemic and the lack of specific assessment instruments for this population.

Objectives: To identify the instruments used to evaluate functional capacity in COVID-19 patients hospitalized in COVID-19 wards and ICUs and the associations between use of assessment instruments and physiotherapist characteristics METHODS: The survey was conducted using REDCap web-based application, following the Consensus-Based Checklist for Reporting of Survey Studies guidelines. A non-probability recruitment approach aimed at physiotherapists who had treated hospitalized patients with COVID-19 in Brazil.
