Jean-Baptiste Denys
Jean-Baptiste Denys (1643 – 3 October 1704) was a French physician notable for having performed the first fully documented human blood transfusion, a xenotransfusion. He studied in Montpellier and was the personal physician to King Louis XIV. Early life Jean Baptiste Denys was born in the 1630s, although his birth had gone unnoticed and undocumented. He was born in a family of modest means, in fact, his father was an artisan who specialized in water pumps, which was seeing an increase in popularity with new elaborate systems being introduced. The passion of Denys towards Medicine was also induced by his medical condition, in fact, he suffered from Asthma. Education Despite his family's humble origins, he obtained a bachelor in theology at the College des Grassins and a medical degree at the Faculty of Medicine in Montpellier, when barely thirty. Denys’ ambition drew him to attempt a career in Paris, however, the bad reputation and its location made him an outside ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physician
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Alum
Potassium alum, potash alum, or potassium aluminium sulfate is a chemical compound: the double sulfate of potassium and aluminium, with chemical formula KAl(SO4)2. It is commonly encountered as the dodecahydrate, KAl(SO4)2·12H2O. It crystallizes in an octahedral structure in neutral solution and cubic structure in an alkali solution with space group P a −3 and lattice parameter of 12.18 Ã….

Grand Châtelet
The Grand Châtelet was a stronghold in Ancien Régime Paris, on the right bank of the Seine, on the site of what is now the Place du Châtelet; it contained a court and police headquarters and a number of prisons. The original building on the site may have been a wooden tower constructed by Charles the Bald in 870 to defend the then new Grand-Pont bridge (now replaced by the Pont au Change), but it is known that Louis VI built a stronger structure in stone, a ''châtelet'' ('small castle'), in 1130; it was called the Grand Châtelet in contrast to the Petit Châtelet built around the same time at the end of the Petit Pont, on the south bank of the Seine. It lost its defensive purpose in 1190 when Philip Augustus built a rampart around the perimeter of the city; from then on it served as the headquarters of the ''prévôt de Paris'', the official "charged with protection of royal rights, oversight of royal administration, and execution of royal justice" in late medieval Paris.

Leech
Leeches are segmented parasitic or predatory worms that comprise the subclass Hirudinea within the phylum Annelida. They are closely related to the oligochaetes, which include the earthworm, and like them have soft, muscular segmented bodies that can lengthen and contract. Both groups are hermaphrodites and have a clitellum, but leeches typically differ from the oligochaetes in having suckers at both ends and in having ring markings that do not correspond with their internal segmentation. The body is muscular and relatively solid, and the coelom, the spacious body cavity found in other annelids, is reduced to small channels. The majority of leeches live in freshwater habitats, while some species can be found in terrestrial or marine environments. The best-known species, such as the medicinal leech, ''Hirudo medicinalis'', are hematophagous, attaching themselves to a host with a sucker and feeding on blood, having first secreted the peptide hirudin to prevent the blood from c ...

Henri Louis Habert De Montmor
Henri Louis Habert de Montmor ( 1600, Paris – 21 January 1679, Paris) was a French scholar and man of letters. Biography Cousin to Philippe Habert and Germain Habert, he became conseiller du roi aged 25, then in 1632 rose to become maître des requêtes, a post he gained thanks to the fortune of his father, treasurer extraordinary for war and treasurer of savings. He married Henriette-Marie de Buade, sister of Louis de Buade de Frontenac, future governor of New France. He attended on Marie de Gournay and wrote Latin epigrams. In 1634, he was elected an inaugural member of the Académie française, pronouncing its fifth discourse but soon becoming a dissenting member as well as its last inaugural member to die. An avid supporter of Descartes, Habert wrote a poem on Cartesian physics entitled ''De rerum naturae'' and collected scientific instruments. He was a friend of Mersenne, who dedicated his ''Harmonie Universelle'' to Montmor, and a great friend of Pierre Gassendi, who ...

Charles Perrault
Charles Perrault ( , also , ; 12 January 1628 – 16 May 1703) was an iconic French author and member of the Académie Française. He laid the foundations for a new literary genre, the fairy tale, with his works derived from earlier folk tales, published in his 1697 book ''Histoires ou contes du temps passé'' (''Stories or Tales from Past Times''). The best known of his tales include ''Le Petit Chaperon Rouge'' ("Little Red Riding Hood"), ''Cendrillon'' ("Cinderella"), ''Le Maître chat ou le Chat botté'' ("Puss in Boots"), ''La Belle au bois dormant'' ("Sleeping Beauty"), and ''Barbe Bleue'' ("Bluebeard"). Some of Perrault's versions of old stories influenced the German versions published by the Brothers Grimm more than 100 years later. The stories continue to be printed and have been adapted to most entertainment formats. Perrault was an influential figure in the 17th-century French literary scene, and was the leader of the Modern faction during the Quarrel of the Ancients ...

Scientific Control
A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable (i.e. confounding variables). This increases the reliability of the results, often through a comparison between control measurements and the other measurements. Scientific controls are a part of the scientific method. Controlled experiments Controls eliminate alternate explanations of experimental results, especially experimental errors and experimenter bias. Many controls are specific to the type of experiment being performed, as in the molecular markers used in SDS-PAGE experiments, and may simply have the purpose of ensuring that the equipment is working properly. The selection and use of proper controls to ensure that experimental results are valid (for example, absence of confounding variables) can be very difficult. Control measurements may also be used for other purposes: for example, a measurement of a microphone's background noise in ...

Circulatory System
The blood circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek ''kardia'' meaning ''heart'', and from Latin ''vascula'' meaning ''vessels''). The circulatory system has two divisions, a systemic circulation or circuit, and a pulmonary circulation or circuit. Some sources use the terms ''cardiovascular system'' and ''vascular system'' interchangeably with the ''circulatory system''. The network of blood vessels are the great vessels of the heart including large elastic arteries, and large veins; other arteries, smaller arterioles, capillaries that join with venules (small veins), and other veins. The Closed circulatory system, circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels. Some in ...

Dissection
Dissection (from Latin ' "to cut to pieces"; also called anatomization) is the dismembering of the body of a deceased animal or plant to study its anatomical structure. Autopsy is used in pathology and forensic medicine to determine the cause of death in humans. Less extensive dissection of plants and smaller animals preserved in a formaldehyde solution is typically carried out or demonstrated in biology and natural science classes in middle school and high school, while extensive dissections of cadavers of adults and children, both fresh and preserved are carried out by medical students in medical schools as a part of the teaching in subjects such as anatomy, pathology and forensic medicine. Consequently, dissection is typically conducted in a morgue or in an anatomy lab. Dissection has been used for centuries to explore anatomy. Objections to the use of cadavers have led to the use of alternatives including virtual dissection of computer models. Overview Plant and animal b ...

Barber Surgeon
The barber surgeon, one of the most common European medical practitioners of the Middle Ages, was generally charged with caring for soldiers during and after battle. In this era, surgery was seldom conducted by physicians, but instead by barbers, who, possessing razors and coordination indispensable to their trade, were called upon for numerous tasks ranging from cutting hair to amputating limbs. In this period, surgical mortality was very high due to blood loss and infection. Yet, since doctors thought that blood letting treated illness, barbers also applied leeches. Meanwhile, physicians considered themselves to be above surgery. Physicians mostly observed surgical patients and offered consulting, but otherwise often chose academia or working in universities. Some chose to reside in castles, where they treated the wealthy. Middle Ages in Europe Due to religious and sanitary monastic regulations, monks had to maintain their tonsure (the traditional baldness on the top of th ...
