International Society of Nephrology force to provide emergency dialysis services in areas struck by disasters (usually earthquakes), where numerous victims may develop acute renal failure due to crush syndrome. Supported by Médecins Sans Frontières, industry sponsors and professional associations, the Renal Disaster Relief Task Force sends renal nurses, technicians and doctors to the affected area. Since its establishment, it has assisted in a number of major earthquakes in several countries. The society publishes four medical journals: "Kidney International", "Kidney International Supplements", "Kidney International Reports", and "Seminars in Nephrology". The current leadership of the ISN includes John Feehally (president), Adeera Levin (secretary general), Victor Schuster
Circumventricular organs that information neurally to other brain regions. Through their neural circuitry, they provide direct information to the autonomic nervous system from the systemic circulation. The secretory organs include the subcommissural organ (SCO), the pituitary gland, the median eminence, and the pineal gland. These organs are responsible for secreting hormones and glycoproteins into the peripheral blood using feedback from both the brain environment and external stimuli. All of the circumventricular organs, except the subcommissural organ, contain extensive vasculature and permeable capillaries which define a sensory and secretory system within the brain. Furthermore, all CVOs contain neural tissue, enabling a neuroendocrine role.
