Reinier De Graaf
Regnier de Graaf (English spelling), original Dutch spelling Reinier de Graaf, or Latinized Reijnerus de Graeff (30 July 164117 August 1673) was a Dutch physician, physiologist and anatomist who made key discoveries in reproductive biology. He specialized in iatrochemistry and iatrogenesis, and was the first to develop a syringe to inject dye into human reproductive organs so that he could understand their structure and function. Biography De Graaf was born in Schoonhoven as the son of an carpenter/engineer or architect and studied medicine in Leuven (1658), Utrecht and Leiden (1663).https://www.ntvg.nl/system/files/publications/1974107890001a.pdf There his co-students were Jan Swammerdam, Niels Stensen, Ole Borch and Frederik Ruysch, cooperating with professor Franciscus Sylvius, Johannes van Horne and Lucas Schacht. All of them were interested in the organs of procreation and influenced by Rene Descartes' iatrophysical approach. He submitted his doctoral thesis on ...

Niels Stensen
Niels Steensen ( da, Niels Steensen; Latinization (literature), Latinized to ''Nicolaus Steno'' or ''Nicolaus Stenonius''; 1 January 1638 – 25 November 1686History of Geology – Steno – Aber, James S. 2007. Retrieved 11 January 2012. ) was a Danish people, Danish scientist, a pioneer in both anatomy and geology who became a Catholic Church, Catholic bishop in his later years. Steensen was trained in the classical texts on science; however, by 1659 he seriously questioned accepted knowledge of the natural world. Importantly he questioned explanations for tear production, the idea that fossils grew in the ground and explanations of rock formation. His investigations and his subsequent conclusions on fossils and rock formation have led scholars to consider him one of the founders of modern strat ...

Dutch Republic
The United Provinces of the Netherlands, also known as the (Seven) United Provinces, officially as the Republic of the Seven United Netherlands (Dutch: ''Republiek der Zeven Verenigde Nederlanden''), and commonly referred to in historiography as the Dutch Republic, was a federal republic that existed from 1579, during the Dutch Revolt, to 1795 (the Batavian Revolution). It was a predecessor state of the Netherlands and the first fully independent Dutch nation state. The republic was established after seven Dutch provinces in the Spanish Netherlands revolted against rule by Spain. The provinces formed a mutual alliance against Spain in 1579 (the Union of Utrecht) and declared their independence in 1581 (the Act of Abjuration). It comprised Groningen, Frisia, Overijssel, Guelders, Utrecht, Holland and Zeeland. Although the state was small and contained only around 1.5 million inhabitants, it controlled a worldwide network of seafaring trade routes. Through its tradin ...

Jean Chapelain
Jean Chapelain (4 December 1595 – 22 February 1674) was a French poet and critic during the Grand Siècle, best known for his role as an organizer and founding member of the Académie française. Chapelain acquired considerable prestige as a literary critic, but his own major work, an epic poem about Joan of Arc called "La Pucelle," (1656) was lampooned by his contemporary Nicolas Boileau-Despréaux.

Doctor Of Medicine
Doctor of Medicine (abbreviated M.D., from the Latin language, Latin ''Medicinae Doctor'') is a medical degree, the meaning of which varies between different jurisdictions. In the United States, and some other countries, the M.D. denotes a professional degree. This generally arose because many in 18th-century medical professions trained in Scotland, which used the M.D. degree nomenclature. In England, however, Bachelor of Medicine, Bachelor of Surgery was used and eventually in the 19th century became the standard in Scotland too. Thus, in the United Kingdom, Republic of Ireland, Ireland and other countries, the M.D. is a research doctorate, honorary degree, honorary doctorate or applied clinical degree restricted to those who already hold a professional degree (Bachelor's/Master's/Doctoral) in medicine. In those countries, the equivalent professional degree to the North American, and some others use of M.D., is still typically titled Bachelor of Medicine, Bachelor of Surgery (M.B ...

Life Bourdelot studied at the Sorbonne (1629) and travelled in 1634 to Rome in the company of count François de Noailles. In 1638 he came back to France and was appointed as the private doctor of the Condé family.

Pancreas
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e. it has both an endocrine and a digestive exocrine function. 99% of the pancreas is exocrine and 1% is endocrine. As an endocrine gland, it functions mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin, and pancreatic polypeptide. As a part of the digestive system, it functions as an exocrine gland secreting pancreatic juice into the duodenum through the pancreatic duct. This juice contains bicarbonate, which neutralizes acid entering the duodenum from the stomach; and digestive enzymes, which break down carbohydrates, proteins, and fats in food entering the duodenum from the stomach. Inflammation of the pancreas is known as pancreatitis, with common causes including chronic alcohol use and gallstones. Becaus ...

Doctoral
A doctorate (from Latin ''docere'', "to teach"), doctor's degree (from Latin ''doctor'', "teacher"), or doctoral degree is an academic degree awarded by universities and some other educational institutions, derived from the ancient formalism ''licentia docendi'' ("licence to teach"). In most countries, a research degree qualifies the holder to teach at university level in the degree's field or work in a specific profession. There are a number of doctoral degrees; the most common is the Doctor of Philosophy (PhD), awarded in many different fields, ranging from the humanities to scientific disciplines. In the United States and some other countries, there are also some types of technical or professional degrees that include "doctor" in their name and are classified as a doctorate in some of those countries. Professional doctorates historically came about to meet the needs of practitioners in a variety of disciplines. Many universities also award honorary doctorates to individuals de ...

Iatrophysics
Iatrophysics or iatromechanics (fr. Greek) is the medical application of physics. It provides an explanation for medical practices with mechanical principles. It was a school of medicine in the seventeenth century which attempted to explain physiological phenomena in mechanical terms. Believers of iatromechanics thought that physiological phenomena of the human body followed the laws of physics. It was related to iatrochemistry in studying the human body in a systematic manner based on observations from the natural world though it had more emphasis on mathematical models rather than chemical processes. Background The Age of Enlightenment was an era of radically changing ways of thought in Western politics, philosophy, and science. Major sociological changes occurred in the Enlightenment, as well as industrial and scientific. In medicine, the Enlightenment brought several discoveries and studies that were impacted by changing ways of thought. For example, capillaries were discov ...

Procreation
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. Reproduction is a fundamental feature of all known life; each individual organism exists as the result of reproduction. There are two forms of reproduction: asexual and sexual. In asexual reproduction, an organism can reproduce without the involvement of another organism. Asexual reproduction is not limited to single-celled organisms. The cloning of an organism is a form of asexual reproduction. By asexual reproduction, an organism creates a genetically similar or identical copy of itself. The evolution of sexual reproduction is a major puzzle for biologists. The two-fold cost of sexual reproduction is that only 50% of organisms reproduce and organisms only pass on 50% of their genes.John Maynard Smith ''The Evolution of Sex'' 1978. Sexual reproduction typically requires the sexual interaction of two specialize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
