Integrative analysis of miRNAs and proteins in plasma extracellular vesicles of patients with familial hypercholesterolemia.

Background And Aims: Familial Hypercholesterolemia (FH) is a monogenic disease that leads to early-onset atherosclerosis. Causative mutations in FH-related genes are found in 60-80 % of patients, while epigenetic factors may contribute to mutation-negative cases. This study analyzed miRNAs and proteins from plasma-derived extracellular vesicles (EVs) of FH patients to explore their contribution in FH diagnosis.

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.

Enriched environment prevents hypernociception and depression-like behavior in a psychiatric disorder and neuropathic pain comorbidity experimental condition.

Pain is a multifactorial debilitating condition associated with some psychiatric comorbidities such as generalized anxiety and depression. Concerning pharmacological treatment, which is often inefficient or associated with intense side effects, the physical and social context may be fundamental for patient's health improvement. In this sense, we sought to assess the impact of an enriched environment (EE) on neuropathic pain (NP) and depression comorbid.

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.

Metal concentrations, oxidative status and histopathological evaluation of fish species from Doce River, Brazil, after the Fundao dam collapse.

Eight years after the tailings dam collapse in Mariana, MG, Brazil, several aspects of this massive disaster are yet to be elucidated. Our goal was to investigate the impact of the mud flow on 16 fish species collected across 15 points from the Doce River, addressing 12 metal concentrations, tissue oxidative status (antioxidant enzymes and stress biomarkers), and histopathological analyses. The species Trachelyopterus striatulus, Prochilodus vimboides, Loricariichthys castaneus, Lophiosilurus alexandri, Hypostomus affinis, Hoplias intermedius were shown to be the most affected regarding the gills tissue integrity; Hypostomus affinis, Oligosarcus acutirostris, Lophiosilurus alexandri, Pygocentrus nattereri, Hoplosternum littorale, and Loricariichthys castaneus showed the highest levels of liver health.
