Here are the events that happened on 9/9 polite
September 9, 2000: For the first time, a hole in the Ozone floor reached the densely populated cities
On September 9, 2000, the hole in the Ozone floor located on the South Pole first reached a densely populated city, after expanding to a record size. During the two days, September 9 and September 10, the hole passed through cities in southern Chile, and people here were exposed to high radiation ultraviolet rays.
Exposure to these rays will cause skin cancer, and they contribute to the destruction of micro-organisms - the first member in the food chain. Previously, this hole only existed in the Antarctic region and surrounding waters. Data from NASA's US Space Agency said the hole covered an area of 11.4 million square miles - three times the size of the United States.
September 9, 1853: Pierre Marie's birthday
Pierre Marie is a French neuroscientist who has made fundamental contributions to the discipline of endocrinology . He was educated at Salpetriere under the guidance of Jean Martin Charcot, and from the beginning of his career, he was interested in neuropathy. His doctoral dissertation is about Basedow's disease and manifests its characteristic tremor on the tip of the limb.
In 1982, he published a series of articles on spinal diseases. He studied and became the first to describe extreme disease. Marie's discovery of the pituitary disorder's developmental disorder is a fundamental contribution to the endocrinology specialization.
September 9, 2003: Marthe Vogt's death day
Marthe Vogt is a German-based pharmacologist - He left Germany to England and became a leading expert in neurotransmitters . She is the co-author of an article published in 1936, demonstrating that Acetylcholine from spinal cord-derived nerve fibers stimulates the activity of muscle fibers. Later, she showed that epinephrine and noepinephrine hormones help brain cells communicate with each other.
Her article on sympathin published in 1954 contributed to a way to change the lives of mental patients. Modern antidepressants with a primary foundation are increased availability of amines, based on the principle that these amines first appear and are activated in the brain - that is Vorte's theory.
