The periaqueductal gray matter (PAG) is rich in mu and kappa opioid receptors, and this system is involved in thermoregulation, analgesia, and defensive behaviors. No study approached the involvement of the PAG opioids in ...

Anurans regulate short-term oscillations in blood pressure through changes in heart rate (f(H)), vascular resistance and lymphatic f(H). Lung ventilation in anurans is linked to blood volume homeostasis by facilitating ...

For an adequate blood supply to support metabolic demands, vertebrates regulate blood pressure to maintain sufficient perfusion to avoid ischemia and other tissue damage like edema. Using a pharmacological approach ...

Receptors of the transient receptor potential (TRP) channels superfamily are expressed in many tissues and have different physiological functions. However, there are few studies investigating the role of these channels in ...
