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.

Spinal arachnoid diverticula in cats: Clinical presentation, diagnostic imaging findings, treatment, and outcome.

Background: Spinal arachnoid diverticulum (SAD) is considered a rare disease in cats. Previous reports mainly classified SAD in cats as acquired.

Hypothesis/objectives: The aim of this study was to describe the signalment, clinical presentation, diagnostic imaging findings, and outcome in a group of cats with SAD.

Pharmacological blockade of infection chronification modulates oxy-inflammation and prevents the activation of stress-induced premature senescence markers in schistosomiasis.

Chronic inflammation, oxidative stress, and DNA damage are observed in schistosomiasis and premature aging. However, the potential of these events to trigger stress-induced premature senescence (SIPS) throughout schistosomiasis progression remains overlooked, especially in response to the first-line pharmacological treatment. Thus, we investigated the relationship between oxidative stress and SIPS sentinel markers in untreated Schistosoma mansoni-infected mice and those receiving praziquantel (Pz)-based reference treatment.

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.

Comorbidities, long-term outcome and poststroke epilepsy associated with ischemic stroke - A multicenter observational study of 125 dogs.

Background: Little is known regarding the comorbidities and prognostic factors associated with the long-term outcome of ischemic stroke in dogs. Although poststroke epilepsy is a well-recognized syndrome in people, it is unclear if this phenomenon also occurs in dogs.

Hypothesis/objective: Document comorbidities, long-term outcome (survival and stroke recurrence), and occurrence of epileptic seizures associated with ischemic stroke.
