Richard Lower (physician)
Richard Lower ( – 17 January 1691) was an English physician who heavily influenced the development of medical science. He is most remembered for his pioneering work on blood transfusion and the function of the cardiopulmonary system, which he described in his book '' Tractatus de Corde''. Life Lower was born in St Tudy, Cornwall, and studied at Westminster School, where he met John Locke, as well as Christ Church, Oxford, where he met Thomas Willis. He followed Willis to London, where he carried out anatomical research, some in partnership with Robert Hooke. His major work, ''Tractatus de Corde'' (1669), was concerned with the workings of the heart and lungs. Lower also experimented with blood transfusion. Lower formed part of an informal research team, performing laboratory experiments at the University of Oxford during the Interregnum. He was a pioneer of experimental physiology. Lower was a medical student under Willis (Professor of Natural Philosophy from 1660 to 1675), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bodmin
Bodmin () is a town and civil parish in Cornwall, England, United Kingdom. It is situated south-west of Bodmin Moor. The extent of the civil parish corresponds fairly closely to that of the town so is mostly urban in character. It is bordered to the east by Cardinham parish, to the southeast by Lanhydrock parish, to the southwest and west by Lanivet parish, and to the north by Helland parish. Bodmin had a population of 14,736 as of the 2011 Census. It was formerly the county town of Cornwall until the Crown Courts moved to Truro which is also the administrative centre (before 1835 the county town was Launceston). Bodmin was in the administrative North Cornwall District until local government reorganisation in 2009 abolished the District (''see also Cornwall Council''). The town is part of the North Cornwall parliamentary constituency, which is represented by Scott Mann MP. Bodmin Town Council is made up of sixteen councillors who are elected to serve a term of four years. ... [...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] |
Anne, Queen Of Great Britain
Anne (6 February 1665 – 1 August 1714) was Queen of England, Scotland and Ireland from 8 March 1702 until 1 May 1707. On 1 May 1707, under the Acts of Union, the kingdoms of England and Scotland united as a single sovereign state known as Great Britain. Anne continued to reign as Queen of Great Britain and Ireland until her death. Anne was born in the reign of Charles II to his younger brother and heir presumptive, James, whose suspected Roman Catholicism was unpopular in England. On Charles's instructions, Anne and her elder sister Mary were raised as Anglicans. Mary married their Dutch Protestant cousin, William III of Orange, in 1677, and Anne married Prince George of Denmark in 1683. On Charles's death in 1685, James succeeded to the throne, but just three years later he was deposed in the Glorious Revolution of 1688. Mary and William became joint monarchs. Although the sisters had been close, disagreements over Anne's finances, status, and choice of acquaintances ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James II Of England
James VII and II (14 October 1633 16 September 1701) was King of England and King of Ireland as James II, and King of Scotland as James VII from the death of his elder brother, Charles II, on 6 February 1685. He was deposed in the Glorious Revolution of 1688. He was the last Catholic monarch of England, Scotland, and Ireland. His reign is now remembered primarily for conflicts over religious tolerance, but it also involved struggles over the principles of absolutism and the divine right of kings. His deposition ended a century of political and civil strife in England by confirming the primacy of the English Parliament over the Crown. James succeeded to the thrones of England, Ireland, and Scotland following the death of his brother with widespread support in all three countries, largely because the principles of eligibility based on divine right and birth were widely accepted. Tolerance of his personal Catholicism did not extend to tolerance of Catholicism in general, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles II Of England, Scotland And Ireland
Charles II (29 May 1630 – 6 February 1685) was King of Scotland from 1649 until 1651, and King of England, Scotland and Ireland from the 1660 Restoration of the monarchy until his death in 1685. Charles II was the eldest surviving child of Charles I of England, Scotland and Ireland and Henrietta Maria of France. After Charles I's execution at Whitehall on 30 January 1649, at the climax of the English Civil War, the Parliament of Scotland proclaimed Charles II king on 5 February 1649. But England entered the period known as the English Interregnum or the English Commonwealth, and the country was a de facto republic led by Oliver Cromwell. Cromwell defeated Charles II at the Battle of Worcester on 3 September 1651, and Charles fled to mainland Europe. Cromwell became virtual dictator of England, Scotland and Ireland. Charles spent the next nine years in exile in France, the Dutch Republic and the Spanish Netherlands. The political crisis that followed Cromwell's death in 1658 ...

Dropsy
Edema, also spelled oedema, and also known as fluid retention, dropsy, hydropsy and swelling, is the build-up of fluid in the body's tissue. Most commonly, the legs or arms are affected. Symptoms may include skin which feels tight, the area may feel heavy, and joint stiffness. Other symptoms depend on the underlying cause. Causes may include venous insufficiency, heart failure, kidney problems, low protein levels, liver problems, deep vein thrombosis, infections, angioedema, certain medications, and lymphedema. It may also occur after prolonged sitting or standing and during menstruation or pregnancy. The condition is more concerning if it starts suddenly, or pain or shortness of breath is present. Treatment depends on the underlying cause. If the underlying mechanism involves sodium retention, decreased salt intake and a diuretic may be used. Elevating the legs and support stockings may be useful for edema of the legs. Older people are more commonly affected. The word is ...

Catarrh
Catarrh is an exudate of inflamed mucous membranes in one of the airways or cavities of the body, usually with reference to the throat and paranasal sinuses. It can result in a thick exudate of mucus and white blood cells caused by the swelling of the mucous membranes in the head in response to an infection. It is a symptom usually associated with the common cold, pharyngitis, and chesty coughs, but it can also be found in patients with adenoiditis, otitis media, sinusitis or tonsillitis. The phlegm produced by catarrh may either discharge or cause a blockage that may become chronic. The word "catarrh" was widely used in medicine since before the era of medical science, which explains why it has various senses and in older texts may be synonymous with, or vaguely indistinguishable from, common cold, nasopharyngitis, pharyngitis, rhinitis, or sinusitis. The word is no longer as widely used in American medical practice, mostly because more precise words are available for any part ...

Hydrocephalus
Hydrocephalus is a condition in which an accumulation of cerebrospinal fluid (CSF) occurs within the brain. This typically causes increased intracranial pressure, pressure inside the skull. Older people may have headaches, double vision, poor balance, urinary incontinence, personality changes, or mental impairment. In babies, it may be seen as a rapid increase in head size. Other symptoms may include vomiting, sleepiness, seizures, and Parinaud's syndrome, downward pointing of the eyes. Hydrocephalus can occur due to birth defects or be acquired later in life. Associated birth defects include neural tube defects and those that result in aqueductal stenosis. Other causes include meningitis, brain tumors, traumatic brain injury, intraventricular hemorrhage, and subarachnoid hemorrhage. The four types of hydrocephalus are communicating, noncommunicating, ''ex vacuo'', and normal pressure hydrocephalus, normal pressure. Diagnosis is typically made by physical examination and medic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerebrospinal Fluid
Cerebrospinal fluid (CSF) is a clear, colorless body fluid found within the tissue that surrounds the brain and spinal cord of all vertebrates. CSF is produced by specialised ependymal cells in the choroid plexus of the ventricles of the brain, and absorbed in the arachnoid granulations. There is about 125 mL of CSF at any one time, and about 500 mL is generated every day. CSF acts as a shock absorber, cushion or buffer, providing basic mechanical and immunological protection to the brain inside the skull. CSF also serves a vital function in the cerebral autoregulation of cerebral blood flow. CSF occupies the subarachnoid space (between the arachnoid mater and the pia mater) and the ventricular system around and inside the brain and spinal cord. It fills the ventricles of the brain, cisterns, and sulci, as well as the central canal of the spinal cord. There is also a connection from the subarachnoid space to the bony labyrinth of the inner ear via the perilymphat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circle Of Willis
The circle of Willis (also called Willis' circle, loop of Willis, cerebral arterial circle, and Willis polygon) is a circulatory anastomosis that supplies blood to the brain and surrounding structures in reptiles, birds and mammals, including humans. It is named after Thomas Willis (1621–1675), an English physician. Structure The circle of Willis is a part of the cerebral circulation and is composed of the following arteries: * Anterior cerebral artery (left and right) * Anterior communicating artery * Internal carotid artery (left and right) * Posterior cerebral artery (left and right) * Posterior communicating artery (left and right) The middle cerebral arteries, supplying the brain, are not considered part of the circle of Willis. Origin of arteries The left and right internal carotid arteries arise from the left and right common carotid arteries. The posterior communicating artery is given off as a branch of the internal carotid artery just before it divides into its termi ...

Sir Edmund King
Sir Edmund King (c.1630–1709), also Edmund Freeman, Edmond King, was an English surgeon and physician. He is known as an experimentalist, and also for his attendance on Charles II of England. Life He was the eldest son of Edmond King (Kinge, Freeman) of Northampton, a surgeon and physician, baptised in 1630. He practised, after apprenticeship, as a surgeon in London. He lived at first in Little Britain, London, and had a museum in his house which he took pleasure in showing to students. He used to keep dried specimens, such as the ileocecal valve, pressed in a large paper book, and he dissected animals as well as the human subject. Around 1665 King took a house in Hatton Garden, London and was married at St. Andrew's Church, Holborn, on 20 June 1666, to Rebecca Polsted of the adjoining parish of St. Sepulchre. Also in 1666 he was elected a Fellow of the Royal Society. Gilbert Sheldon, the archbishop of Canterbury, created him M.D., a Lambeth degree; he was incorporated at Camb ...

Xenotransfusion
Xenotransfusion (from Greek '' xenos-'' ''strange'' or ''foreign''), a form of xenotransplantation, was initially defined as the transfer of blood from one species into the veins of another. In most cases, it is a transfer of blood between a non-human animal and a human. However, further experimentation has been done between various non-human animal species. This procedure can be performed without affecting the health of the donor, as only about 10% of their blood volume is used each time. Utilizing the unlimited blood supply from animal sources eliminates the risk of transmitting infectious diseases between humans. In 1658, Dom Robert des Gabets, a French monk, introduced the idea of xenotransfusion at a scientific society meeting. This society later afforded the French Academy of Sciences. Currently there are not any laws prohibiting the practice of xenotransfusion, but some ethical issues have been identified by the Ethics Committee of the International Xenotransplantation Asso ...
