Palmitate Compromises C6 Astrocytic Cell Viability and Mitochondrial Function
(2024-03-12)Consumption of high-fat diets (HFD) is associated with brain alterations, including changes in feeding behavior, cognitive decline, and dementia. Astrocytes play a role in HFD-induced neuroinflammation and brain dysfunction; ... -
CD8 T cells are dispensable for experimental autoimmune prostatitis induction and chronic pelvic pain development
(2024-05-14)Introduction: Chronic Pelvic Pain Syndrome or Chronic Prostatitis (CPPS/CP) is the most prevalent urologic affliction among young adult men. It is a challenging condition to treat, which significantly decreases patient ... -
CD39 expression by regulatory T cells participates in CD8+ T cell suppression during experimental Trypanosoma cruzi infection
(2024-04-29)An imbalance between suppressor and effector immune responses may preclude cure in chronic parasitic diseases. In the case of Trypanosoma cruzi infection, specialized regulatory Foxp3+ T (Treg) cells suppress protective ... -
The Limitations of Systematic Reviews With Meta-Analyses in Sport Science. Editorial
(2024-04-24)It is generally argued that systematic reviews are necessary because of the possibility of some subjective bias in narrative reviews. Thus, SRwMs are considered the gold standard of scientific evidence. However, “all that ... -
Protective effect of nitro-oleic acids in neovascularization, gliosis and neurodegeneration in a mouse model of oxygen-induced retinopathy
