Jean-Baptiste De Sénac
Jean-Baptiste de Sénac (1693–1770) was a French physician, born in the district of Lombez in Gascony, France. Early life and education Details of Sénac's early life are sketchy. It is generally thought that he studied medicine at the University of Leiden, the Netherlands. He later studied in London, England, where one of his instructors was John Freind (1675–1728). Beginning in 1723, Sénac practiced medicine in Paris, serving (from 1752 to 1770) as a personal physician to King Louis XV. Contributions to medicine Sénac is remembered for important studies of the heart in an era when cardiological medicine was rudimentary. In 1749 he published a book on cardiology called ''Traité de la structure du coeur, de son action, et de ses maladies'' (Treatise on the structure of the heart, its action, and its diseases), an influential work that systematically dealt with physiological, anatomical and pathological issues involving the heart. In the treatise, he discusses heart disor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gascony
Gascony (; ) was a province of the southwestern Kingdom of France that succeeded the Duchy of Gascony (602–1453). From the 17th century until the French Revolution (1789–1799), it was part of the combined Province of Guyenne and Gascony. The region is vaguely defined, and the distinction between Guyenne and Gascony is unclear; by some they are seen to overlap, while others consider Gascony a part of Guyenne. Most definitions put Gascony east and south of Bordeaux. It is currently divided between the region of Nouvelle-Aquitaine (departments of Landes, Pyrénées-Atlantiques, southwestern Gironde, and southern Lot-et-Garonne) and the region of Occitanie (departments of Gers, Hautes-Pyrénées, southwestern Tarn-et-Garonne, and western Haute-Garonne). Gascony was historically inhabited by Basque-related people who appear to have spoken a language similar to Basque. The name Gascony comes from the same root as the word Basque (see Wasconia below).

Heart Disorders
The heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. The heart and blood vessels together make the circulatory system. The pumped blood carries oxygen and nutrients to the tissue, 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, called the mediastinum. In humans, 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. 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 of the heart is made up of three layers: epicardium, ...

People From Gers
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gabriel Sénac De Meilhan
Gabriel Sénac de Meilhan (May 7, 1736 – August 16, 1803) was a French writer. He witnessed the beginning of the French Revolution in Paris, but soon emigrated in 1790 to London and then to Aachen. He wrote a novel, ''L'Émigré'', in 1793. In 1792 he was invited by Catherine II of Russia to become the imperial historiographer, but Catherine was displeased by his manners and dismissed him. Biography Son of Jean-Baptiste de Sénac, physician to Louis XV, he was born in Versailles. He entered the civil service in 1762; two years later he bought the office of master of requests, and in 1766 further advanced his position by a rich marriage. He was successively intendant of La Rochelle, of Aix-en-Provence and of Valenciennes. In 1776 he became intendant-general for war, but was soon compelled to resign. He had hoped to be made Minister of Finance, and was disappointed by the nomination of Necker, of whom he became a bitter opponent. He was intimate with the comtesse de Tess, sist ...

Rhubarb
Rhubarb is the fleshy, edible stalks ( petioles) of species and hybrids (culinary rhubarb) of ''Rheum'' in the family Polygonaceae, which are cooked and used for food. The plant is a herbaceous perennial that grows from short, thick rhizomes. Historically, different plants have been called "rhubarb" in English. The large, triangular leaves contain high levels of oxalic acid and anthrone glycosides, making them inedible. The small flowers are grouped in large compound leafy greenish-white to rose-red inflorescences. The precise origin of culinary rhubarb is unknown. The species '' Rheum rhabarbarum'' (syn. ''R. undulatum'') and '' R. rhaponticum'' were grown in Europe before the 18th century and used for medicinal purposes. By the early 18th century, these two species and a possible hybrid of unknown origin, ''R.'' × ''hybridum'', were grown as vegetable crops in England and Scandinavia. They readily hybridize, and culinary rhubarb was developed by selecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cinchona
''Cinchona'' (pronounced or ) is a genus of flowering plants in the family Rubiaceae containing at least 23 species of trees and shrubs. All are native to the Tropical Andes, tropical Andean forests of western South America. A few species are reportedly naturalization (biology), naturalized in Central America, Jamaica, French Polynesia, Sulawesi, Saint Helena in the South Atlantic, and São Tomé and Príncipe off the coast of tropical Africa, and others have been cultivated in India and Java, where they have formed hybrids. ''Cinchona'' has been historically sought after for its medicinal value, as the bark of several species yields quinine and other alkaloids. These were the only effective treatments against malaria during the height of European colonialism, which made them of great economic and political importance. Trees in the genus are also known as fever trees because of their antimalarial properties. The artificial Quinine total synthesis, synthesis of quinine in 1944, ...

Hypertrophy
Hypertrophy is the increase in the volume of an organ or tissue due to the enlargement of its component cells. It is distinguished from hyperplasia, in which the cells remain approximately the same size but increase in number. Although hypertrophy and hyperplasia are two distinct processes, they frequently occur together, such as in the case of the hormonally induced proliferation and enlargement of the cells of the uterus during pregnancy. Eccentric hypertrophy is a type of hypertrophy where the walls and chamber of a hollow organ undergo growth in which the overall size and volume are enlarged. It is applied especially to the left ventricle of heart. Sarcomeres are added in series, as for example in dilated cardiomyopathy (in contrast to hypertrophic cardiomyopathy, a type of concentric hypertrophy, where sarcomeres are added in parallel).

Atrial Fibrillation
Atrial fibrillation (AF, AFib or A-fib) is an Heart arrhythmia, abnormal heart rhythm (arrhythmia) characterized by fibrillation, rapid and irregular beating of the Atrium (heart), atrial chambers of the heart. It often begins as short periods of abnormal cardiac cycle, beating, which become longer or continuous over time. It may also start as other forms of arrhythmia such as atrial flutter that then transform into AF. Episodes can be asymptomatic. Symptomatic episodes may involve heart palpitations, syncope (medicine), fainting, Presyncope, lightheadedness, Unconsciousness, loss of consciousness, or shortness of breath. Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. It is a type of supraventricular tachycardia. Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the Atrium (heart), atrium to the pulmonary veins.
