Unraveling the numerous factors that drive phenotypic variation in trait expression among animals has long presented a significant challenge. Whereas traits like growth and adult size are often heritable and are passed on from one generation to the next, these can be significantly affected by the quality and quantity of resources provided by one or both parents to their offspring. In many vertebrates, such as birds and mammals, parents raise their young until adult, providing food, shelter, and protection.

Chronic exposure to stress has been considered a risk factor for hypertension, which is also associated with increased bone resorption. This review aimed to investigate the effect of acute and chronic stress, associated with hypertension, on the skeletal system. A comprehensive search was conducted across multiple databases, focusing on peer-reviewed articles published in English.

Background: This study examines the impact of Phα1β, a spider peptide derived from the venom of , on the Kv11.1 potassium channel in HEK293 cells transfected with the human ERG potassium channel. Phα1β inhibits high-voltage calcium channels and acts as an antagonist of the TRPA1 receptor, both of which play crucial roles in pain transduction pathways.

Scorpion envenomation, especially from Hemiscorpius lepturus, poses a significant health risk, leading to considerable morbidity and mortality. The venom's major toxin, which includes phospholipase D (PLD), is responsible for various systemic complications. In prior studies, we identified a native phospholipase D (PLD) toxin as a key lethal factor in the venom of H.

Motor dysfunction and muscle atrophy are typical symptoms of patients with spinal cord injury (SCI). Exercise training is a conventional physical therapy after SCI, but exercise intervention alone may have limited efficacy in reducing secondary injury and promoting nerve regeneration and functional remodeling. Our previous research found that intramedullary pressure after SCI is one of the key factors affecting functional prognosis.
