Induction of ectosome formation by binding of phospholipases D from Loxosceles venoms to endothelial cell surface: Mechanism of interaction.

Members of the phospholipase D (PLD) superfamily found in Loxosceles spider venoms are potent toxins with inflammatory and necrotizing activities. They degrade phospholipids in cell membranes, generating bioactive molecules that activate skin cells. These skin cells, in turn, activate leukocytes involved in dermonecrosis, characterized by aseptic coagulative necrosis.

Influence of acute heat shock on antioxidant defense of tropical fish, Psalidodon bifasciatus.

Psalidodon bifasciatus is a fish species sensitive to physical and chemical changes in water. It serves as a good bioindicator of temperature variations and is utilized in environmental monitoring studies in Brazilian rivers. The objective of this study was to evaluate antioxidant defense biomarkers in the heart, brain, and muscle of P.

Physiological strategies of acute thermal conditions of Rhamdia voulezi collected in the Iguaçu river watershed, Paraná, Brazil: biochemical markers of metabolic and oxidative stress.

Thermal pollution creates substantial challenges that alter energy demand and produce reactive oxygen species that damage fish DNA, proteins, and lipids. Rhamdia voulezi is a species of fish native to the Iguaçu river, Paraná, Brazil, that does not have scientific records of minimum (CT) and maximum (CT) temperatures required for survival. As it is a top predator species in the food chain and lives at temperatures below 22 °C, the loss of the species can cause functional problems in controlling the ecosystem and energy flow.

Efficacy of Cognitive Behavioral Therapy in treating women with endometriosis and chronic pelvic pain: A randomized trial.

This study seeks to assess the efficacy of Cognitive-Behavioral Therapy (CBT) in enhancing coping strategies, alleviating depression, stress, pain perception, and improving the quality of life for women with endometriosis. About 52 patients randomized, categorized into an intervention group ( = 25) and a control group ( = 27) filled out the instruments. A significant positive change was observed in all variables studied within the intervention group compared to the control group.
