Background. Acute ischemic stroke (AIS) is characterized by the sudden loss of blood circulation to an area of the brain, typically in a vascular territory, resulting in a corresponding loss of neurologic function.troke symptoms can result from inadequate cerebral blood flow because of decreased blood pressure (and specifically, decreased cerebral perfusion pressure) or as a result of hematologic hyperviscosity from sickle cell disease or other hematologic illnesses, such as multiple myeloma and polycythemia vera.
Calcitonin. Calcitonin is a peptide hormone produced by cells within the thyroid gland. Calcitonin secretion is stimulated by high blood calcium concentrations, and it acts as a physiologic antagonist to PTH. Osteoclasts have receptors for calcitonin, but the effects are transient.rowth hormone. Growth Hormone (GH) is a growth promoting hormone produced by the pituitary gland. It is anabolic, which means it stimulates bone formation. Growth hormone also: * stimulates the production of insulin-like growth factor 1 (IGF-1) by the skeleton.
By Tom Fordyce What is human growth hormone? Growth hormone is a powerful anabolic hormone that occurs naturally in the human body. It is produced by the pituitary gland in the brain and stimulates the growth of muscle, cartilage, and bone.It is made throughout a person's lifetime but is more plentiful during youth.y Tom Fordyce What is human growth hormone?
