Gasparo Aselli
Gaspare Aselli (or Asellio) ( – 9 September 1625). was an Italian physician noted for the discovery of the lacteal vessels of the lymphatic system. Aselli discovered (or rediscovered) the chylous vessels, and studied systematically the significance of these vascular structures. Life Gaspare Aselli was born in Cremona of a wealthy patrician family. He attended the University of Pavia, where he obtained degrees in medicine, surgery and philosophy. He continued his studies in Milan, where he practiced medicine with great distinction. The Milanese Senate named him an honorary citizen “by virtue of his superlative qualities as doctor and scientist”. In 1612 he was appointed Head Surgeon of the Spanish Armada in Italy. He became professor of anatomy and surgery at the University of Pavia shortly before his death in 1625 at the age of 44. He is buried in Milan, in the church of San Pietro Celestino, near Porta Venezia. Contributions Aselli is regarded as the discoverer of the l ...

Doctor (title)
Doctor is an academic title that originates from the Latin word of the same spelling and meaning. The word is originally an agentive noun of the Latin verb 'to teach'. It has been used as an academic title in Europe since the 13th century, when the first doctorates were awarded at the University of Bologna and the University of Paris. Having become established in European universities, this usage spread around the world. Contracted "Dr" or "Dr.", it is used as a designation for a person who has obtained a doctorate (commonly a PhD/DPhil). In many parts of the world it is also used by medical practitioners, regardless of whether they hold a doctoral-level degree. Origins The doctorate ( la, doceō, lit=I teach) appeared in medieval Europe as a license to teach ( la, licentia docendi, links=no) at a medieval university. Its roots can be traced to the early church when the term "doctor" referred to the Apostles, church fathers and other Christian authorities who taught a ...

Lacteal Vessels
A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids, di- and monoglycerides. These then pass from the intestinal lumen into the enterocyte, where they are re-esterified to form triglyceride. The triglyceride is then combined with phospholipids, cholesterol ester, and apolipoprotein B48 to form chylomicrons. These chylomicrons then pass into the lacteals, forming a milky substance known as chyle. The lacteals merge to form larger lymphatic vessels that transport the chyle to the thoracic duct where it is emptied into the bloodstream at the subclavian vein. At this point, the fats are in the bloodstream in the form of chylomicrons. Once in the blood, chylomicrons are subject to delipidation by lipoprotein lipase. Eventually, enough lipid has been lost and additional apolipoproteins gained, that the resulting particle (now ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood in the circulatory system is also known as ''peripheral blood'', and the blood cells it carries, ''peripheral blood cells''. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lung
The lungs are the primary organs of the respiratory system in humans and most other animals, including some snails and a small number of fish. In mammals and most other vertebrates, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the air and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange. Respiration is driven by different muscular systems in different species. Mammals, reptiles and birds use their different muscles to support and foster breathing. In earlier tetrapods, air was driven into the lungs by the pharyngeal muscles via buccal pumping, a mechanism still seen in amphibians. In humans, the main muscle of respiration that drives breathing is the diaphragm. The lungs also provide airflow that makes vocal sounds including human speech possible. Humans have two lungs, one on the left and on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heart
The heart is a muscular organ in most animals. This organ pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the right heart and their left counterparts as the left heart. Fish, in contrast, have two chambers, an atrium and a ventricle, while most reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chyle
Chyle (from the Ancient Greek, Greek word χυλός ''chylos'', "juice") is a milky bodily fluid consisting of lymph and emulsified fats, or free fatty acids (FFAs). It is formed in the small intestine during digestion of fatty foods, and taken up by lymph vessels specifically known as lacteals. The lipids in the chyle are colloidally suspended in chylomicrons. Clinical significance A chyle fistula occurs when defect(s) of lymphatic vessel(s) result in leakage of lymphatic fluid, typically accumulating in the thoracic (pleural) or abdominal (peritoneal) cavities, leading to a chylous pleural effusion (chylothorax) or chylous ascites, respectively. Diagnosis of a chyle fistula may be accomplished by analysis of pleural/peritoneal fluid. Identifying the source (localizing the lymphatic defect) is often challenging, but may be accomplished with lymphangiography, which is occasionally associated with a serendipitous therapeutic effect (resolution of the leak), thought to be secondar ...

Porta Venezia
Porta Venezia (formerly known as Porta Orientale, Porta Renza and by other names) is one of the historical gates of the city of Milan, Italy. In its present form, the gate dates back to the 19th century; nevertheless, its origins can be traced back to the Medieval and even the Roman walls of the city. The name Porta Venezia is commonly used to refer both to the gate proper and to the surrounding district ("quartiere"), part of the Zone 3 of Milan. Porta Venezia area is undeniably known today as the LGBT-Friendly district of Milan: Via Lecco and its surroundings are Milan's Gay Street with lgbt or lgbt-themed bars and restaurants. In 2019, after a commercial advertisement campaign by Netflix Italia for the 2018 Milano Pride, Mayor Giuseppe Sala announced that Porta Venezia Metro Station would have become a Rainbow Station, thanks to the agreement with the ATM metro service: the rainbow colored wallpaper would have been indefinitely kept making Porta Venezia Italy's first officia ...

Honorary Citizenship
Honorary citizenship is a status bestowed by a city or other government on a foreign or native individual whom it considers to be especially admirable or otherwise worthy of the distinction. The honour usually is symbolic and does not confer any change to citizenship or nationality. North America By Act of Congress, act of United States Congress and presidential assent, an individual may be named an honorary citizen of the United States. Since 1963, it has been awarded to only eight individuals. Honorary Canadian citizenship requires unanimous approval in both houses of Parliament of Canada, Parliament. The only people to ever receive honorary Canadian citizenship are Raoul Wallenberg posthumously in 1985; Nelson Mandela in 2001; the 14th Dalai Lama Tenzin Gyatso in 2006; Aung San Suu Kyi in 2007 (revoked in 2018); Aga Khan IV, Prince Karim Aga Khan in 2009; and Malala Yousafzai in 2014.

Philosophy
Philosophy (from , ) is the systematized study of general and fundamental questions, such as those about existence, reason, knowledge, values, mind, and language. Such questions are often posed as problems to be studied or resolved. Some sources claim the term was coined by Pythagoras ( BCE), although this theory is disputed by some. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation. in . Historically, ''philosophy'' encompassed all bodies of knowledge and a practitioner was known as a ''philosopher''."The English word "philosophy" is first attested to , meaning "knowledge, body of knowledge." "natural philosophy," which began as a discipline in ancient India and Ancient Greece, encompasses astronomy, medicine, and physics. For example, Newton's 1687 ''Mathematical Principles of Natural Philosophy'' later became classified as a book of physics. In the 19th century, the growth of modern research universiti ...
