Henry Souttar
Sir Henry Sessions Souttar (14 December 1875 – 12 November 1964) was a British surgeon with a wide breadth of interests. He trained first as a mathematician and engineer. His engineer’s training enabled him to design and make new types of surgical instrument. His mathematical training made him a leader in setting out the first British guidelines for Radiotherapy. In 1925 he pioneered "blind" open heart surgery on a patient with congenital heart defect. This was not repeated until 1948.T. Holmes Sellors rev. Tom Treasure, ''Oxford Dictionary of National Biography'', Oxford University Press, 2004 Biography Henry Sessions Souttar was born at Birkenhead on 14 December 1875, the only son of Robinson Souttar, Member of Parliament for Dumfries (1895–1900), and his wife Mary. He was educated at Oxford high school and Queen's College, Oxford (1895–8). He gained a double first in mathematics and also studied engineering. In 1904 he married Catharine Edith, daughter of Robert B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiotherapy
Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body. It may also be used as part of adjuvant therapy, to prevent tumor recurrence after surgery to remove a primary malignant tumor (for example, early stages of breast cancer). Radiation therapy is synergistic with chemotherapy, and has been used before, during, and after chemotherapy in susceptible cancers. The subspecialty of oncology concerned with radiotherapy is called radiation oncology. A physician who practices in this subspecialty is a radiation oncologist. Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizing radiation works by damaging the DNA of cancerous tissue l ...

British Medical Association
The British Medical Association (BMA) is a registered trade union for doctors in the United Kingdom. The association does not regulate or certify doctors, a responsibility which lies with the General Medical Council. The association's headquarters are in Tavistock Square, London and it has national offices in Cardiff, Belfast, and Edinburgh, a European office in Brussels and a number of offices in English regions. The BMA has a range of representative and scientific committees and is recognised by National Health Service (NHS) employers as the sole contract negotiator for doctors. The BMA's stated aim is "to promote the medical and allied sciences, and to maintain the honour and interests of the medical profession". History Provincial Medical and Surgical Association and Webster's Medical Association The British Medical Association traces its origins to the Provincial Medical and Surgical Association (PMSA), founded by Sir Charles Hastings on 19 July 1832, and to the "Britis ...

Churchwarden
A churchwarden is a lay official in a parish or congregation of the Anglican Communion or Catholic Church, usually working as a part-time volunteer. In the Anglican tradition, holders of these positions are ''ex officio'' members of the parish board, usually called a vestry, parochial church council, or in the case of a Cathedral parish the chapter. Responsibilities of office Churchwardens have a duty to represent the laity and co-operate with the incumbent (or, in cases of vacancy, the bishop). They are expected to lead the parishioners by setting a good example and encouraging unity and peace. They have a duty to maintain order and peace in the church and churchyard at all times, and especially during services, although this task tends to be devolved to sidesmen.Clements 2018, pp14-16. Churchwardens in many parts of the Anglican Communion are legally responsible for all the property and movable goods belonging to a parish church. If so, they have a duty under ecclesiast ...

St Marylebone Church
St Marylebone Parish Church is an Anglican church on the Marylebone Road in London. It was built to the designs of Thomas Hardwick in 1813–17. The present site is the third used by the parish for its church. The first was further south, near Oxford Street. The church there was demolished in 1400 and a new one erected further north. This was completely rebuilt in 1740–42, and converted into a chapel-of-ease when Hardwick's church was constructed. The Marylebone area takes its name from the church. Located behind the church is St Marylebone School, a Church of England school for girls. Previous churches First church The first church for the parish was built in the vicinity of the present Marble Arch c.1200, and dedicated to St John the Evangelist. Second church In 1400 the Bishop of London gave the parishioners permission to demolish the church of St John and build a new one in a more convenient position, near a recently completed chapel, which could be used until the new chu ...

Royal College Of Surgeons
The Royal College of Surgeons is an ancient college (a form of corporation) established in England to regulate the activity of surgeons. Derivative organisations survive in many present and former members of the Commonwealth. These organisations are now also responsible for training surgeons and setting their examinations. History The earliest form of the Royal College of Surgeons was the "Guild of Surgeons Within the City of London" founded in the 14th century. There was dispute between the surgeons and barber surgeons until an agreement was signed between them in 1493, giving the fellowship of surgeons the power of incorporation. The Guild of Barbers of Dublin received a Royal Charter of Henry VI in 1446, making it the earliest Royal Medical incorporation in Britain or Ireland. This was followed in 1505 by the incorporation of the Barber Surgeons of Edinburgh as a Craft Guild of Edinburgh. This body was granted a royal charter in 1506 by King James IV of Scotland. It was followe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Left Atrium
The atrium ( la, ātrium, , entry hall) is one of two upper chambers in the heart that receives blood from the circulatory system. The blood in the atria is pumped into the heart ventricles through the atrioventricular valves. There are two atria in the human heart – the left atrium receives blood from the pulmonary circulation, and the right atrium receives blood from the venae cavae of the systemic circulation. During the cardiac cycle the atria receive blood while relaxed in diastole, then contract in systole to move blood to the ventricles. Each atrium is roughly cube-shaped except for an ear-shaped projection called an atrial appendage, sometimes known as an auricle. All animals with a closed circulatory system have at least one atrium. The atrium was formerly called the 'auricle'. That term is still used to describe this chamber in some other animals, such as the ''Mollusca''. They have thicker muscular walls than the atria do. Structure Humans have a four-chambered ...

Radon
Radon is a chemical element with the symbol Rn and atomic number 86. It is a radioactive, colourless, odourless, tasteless noble gas. It occurs naturally in minute quantities as an intermediate step in the normal radioactive decay chains through which thorium and uranium slowly decay into various short-lived radioactive elements and lead. Radon itself is the immediate decay product of radium. Its most stable isotope, 222Rn, has a half-life of only 3.8 days, making it one of the rarest elements. Since thorium and uranium are two of the most common radioactive elements on Earth, while also having three isotopes with half-lives on the order of several billion years, radon will be present on Earth long into the future despite its short half-life. The decay of radon produces many other short-lived nuclides, known as "radon daughters", ending at stable isotopes of lead. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malignant Tumour
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol. Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants. In the developing world, 15% of cancers are due to infections such as '' Helicobacter pylori'', hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV). These factors act, at least partly, by changing the genes of a ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radium
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found ...

Craniotome (tool)
A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driverchuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, construction and utility projects. Specially designed versions are made for miniature applications. History Around 35,000 BC, ''Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans The Maya peoples () are an ethnolinguistic group of indigenous peoples ...
