Frederick Ruysch
Frederik Ruysch (; March 28, 1638 – February 22, 1731) was a Dutch botanist and anatomist. He is known for developing techniques for preserving anatomical specimens, which he used to create dioramas or scenes incorporating human parts. His anatomical preparations included over 2,000 anatomical, pathological, zoological, and botanical specimens, which were preserved by either drying or embalming. Ruysch is also known for his proof of valves in the lymphatic system, the vomeronasal organ in snakes, and ''arteria centralis oculi'' (the central artery of the eye). He was the first to describe the disease that is today known as Hirschsprung's disease, as well as several pathological conditions, including intracranial teratoma, enchondromatosis, and Majewski syndrome. Life Frederik Ruysch was born in The Hague as the son of a government functionary and started as the pupil of a druggist. Fascinated by anatomy, he studied at the university of Leiden, under Franciscus Sylvius. His f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hortus Botanicus Amsterdam
Hortus Botanicus is a botanical garden in the Plantage district of Amsterdam, the Netherlands. It is one of the world's oldest botanical gardens. History The Amsterdam city council founded the ''Hortus Botanicus'' (initially named the ''Hortus Medicus'') in 1638 to serve as a herb garden for doctors and apothecaries, as botanical extracts were the primary treatments for illnesses during this time period. Physicians and pharmacists received their training and took exams here. The garden's initial collection was amassed during the 17th century through plants and seeds brought back by traders from the Dutch East India Company for use as medicines and potential commercial possibilities. A single coffee plant in Hortus's collection served as the parent for the entire coffee culture in Central and South America. Likewise, two small potted oil palms brought back from Mauritius produced seeds which were propagated throughout all of Southeast Asia, becoming a major source of reven ...

Midwifery
Midwifery is the health science and health profession that deals with pregnancy, childbirth, and the postpartum period (including care of the newborn), in addition to the sexual and reproductive health of women throughout their lives. In many countries, midwifery is a medical profession (special for its independent and direct specialized education; should not be confused with the medical specialty, which depends on a previous general training). A professional in midwifery is known as a midwife. A 2013 Cochrane review concluded that "most women should be offered midwifery-led continuity models of care and women should be encouraged to ask for this option although caution should be exercised in applying this advice to women with substantial medical or obstetric complications." The review found that midwifery-led care was associated with a reduction in the use of epidurals, with fewer episiotomies or instrumental births, and a decreased risk of losing the baby before 24 weeks' gesta ...

Guild
A guild ( ) is an association of artisans and merchants who oversee the practice of their craft/trade in a particular area. The earliest types of guild formed as organizations of tradesmen belonging to a professional association. They sometimes depended on grants of letters patent from a monarch or other ruler to enforce the flow of trade to their self-employed members, and to retain ownership of tools and the supply of materials, but were mostly regulated by the city government. A lasting legacy of traditional guilds are the guildhalls constructed and used as guild meeting-places. Guild members found guilty of cheating the public would be fined or banned from the guild. Typically the key "privilege" was that only guild members were allowed to sell their goods or practice their skill within the city. There might be controls on minimum or maximum prices, hours of trading, numbers of apprentices, and many other things. These rules reduced free competition, but sometimes mainta ...

Surgery
Surgery ''cheirourgikē'' (composed of χείρ, "hand", and ἔργον, "work"), via la, chirurgiae, meaning "hand work". is a medical specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas. The act of performing surgery may be called a surgical procedure, operation, or simply "surgery". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments or surgical nurse. The person or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and a surgeon's assistant is a person who practices surgical assistance.

Pleuritis
Pleurisy, also known as pleuritis, is inflammation of the membranes that surround the lungs and line the chest cavity (pleurae). This can result in a sharp chest pain while breathing. Occasionally the pain may be a constant dull ache. Other symptoms may include shortness of breath, cough, fever, or weight loss, depending on the underlying cause. The most common cause is a viral infection. Other causes include bacterial infection, pneumonia, pulmonary embolism, autoimmune disorders, lung cancer, following heart surgery, pancreatitis and asbestosis. Occasionally the cause remains unknown. The underlying mechanism involves the rubbing together of the pleurae instead of smooth gliding. Other conditions that can produce similar symptoms include pericarditis, heart attack, cholecystitis, pulmonary embolism, and pneumothorax. Diagnostic testing may include a chest X-ray, electrocardiogram (ECG), and blood tests. Treatment depends on the underlying cause. Paracetamol (acetaminophen ...

Cadavers
A cadaver or corpse is a dead human body that is used by medical students, physicians and other scientists to study anatomy, identify disease sites, determine causes of death, and provide tissue to repair a defect in a living human being. Students in medical school study and dissect cadavers as a part of their education. Others who study cadavers include archaeologists and arts students. The term ''cadaver'' is used in courts of law (and, to a lesser extent, also by media outlets such as newspapers) to refer to a dead body, as well as by recovery teams searching for bodies in natural disasters. The word comes from the Latin word ''cadere'' ("to fall"). Related terms include ''cadaverous'' (resembling a cadaver) and ''cadaveric spasm'' (a muscle spasm causing a dead body to twitch or jerk). A cadaver graft (also called “postmortem graft”) is the grafting of tissue from a dead body onto a living human to repair a defect or disfigurement. Cadavers can be observed for their stag ...

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 ...

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.

Jan Swammerdam
Jan Swammerdam (February 12, 1637 – February 17, 1680) was a Dutch biologist and microscopist. His work on insects demonstrated that the various phases during the life of an insect—egg, larva, pupa, and adult—are different forms of the same animal. As part of his anatomical research, he carried out experiments on muscle contraction. In 1658, he was the first to observe and describe red blood cells. He was one of the first people to use the microscope in dissections, and his techniques remained useful for hundreds of years. Education Swammerdam was baptized on 15 February 1637 in the Oude Kerk Amsterdam. His father was an apothecary, and an amateur collector of minerals, coins, fossils, and insects from around the world. His mother Baertje Jans Corvers died in 1661. As a youngster, Swammerdam had helped his father to take care of his curiosity collection. Despite his father's wish that he should study theology Swammerdam started to study medicine in 1661 at the Univers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
