Alfred Kohn
Alfred Kohn (22 February 1867 – 15 January 1959) headed the Institute of Histology at the Medical Faculty of German University in Prague for 26 years.Nanka O, Grim M. Alfred Kohn, profesor histologie na Nĕmecké Univerzitĕ v Praze lfred Kohn, professor of histology at German University in Prague Cas Lek Cesk. 2008;147(4):240-4. Czech. PMID 18578380. He discovered the nature and origin of parathyroid glands and pioneered research on chromaffin cells and sympathetic paraganglia. Kohn's papers covered topics including the pituitary, interstitial cells of testes, and ovaries, all of which relate to endocrinology. All of his studies were based on descriptive and comparative histological and embryological observations. Kohn was twice the dean of German Medical Faculty, and an honorary member of many scientific societies. He was repeatedly nominated for Nobel Prize for physiology and medicine. Due to his Jewish origin, he was expelled from Deutsche Gesellschaft der Wissenschaften und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Histology
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope. Although one may divide microscopic anatomy into ''organology'', the study of organs, ''histology'', the study of tissues, and ''cytology'', the study of cells, modern usage places all of these topics under the field of histology. In medicine, histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. In the field of paleontology, the term paleohistology refers to the histology of fossil organisms. Biological tissues Animal tissue classification There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. All animal tissues are considered to be subtypes of these four principal tissue types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl-Ferdinands-Universität
Charles University ( cs, Univerzita Karlova, UK; la, Universitas Carolina; german: Karls-Universität), also known as Charles University in Prague or historically as the University of Prague ( la, Universitas Pragensis, links=no), is the oldest and largest university in the Czech Republic. It is one of the List of oldest universities in continuous operation, oldest universities in Europe in continuous operation. Today, the university consists of 17 faculties located in Prague, Hradec Králové, and Plzeň. Charles University belongs among the top three universities in Central and Eastern Europe. It is ranked around 200–300 in the world. History Medieval university (1349–1419) The establishment of a medieval university in Prague was inspired by Holy Roman Emperor Charles IV, Holy Roman Emperor, Charles IV. He asked his friend and ally, Pope Clement VI, to do so. On 26 January 1347 the pope issued the bull establishing a university in Prague, modeled on the University of Paris, ...

Parathyroid
Parathyroid glands are small endocrine glands in the neck of humans and other tetrapods. Humans usually have four parathyroid glands, located on the back of the thyroid gland in variable locations. The parathyroid gland produces and secretes parathyroid hormone in response to a low blood calcium, which plays a key role in regulating the amount of calcium in the blood and within the bones. Parathyroid glands share a similar blood supply, venous drainage, and lymphatic drainage to the thyroid glands. Parathyroid glands are derived from the epithelial lining of the third and fourth pharyngeal pouches, with the superior glands arising from the fourth pouch and the inferior glands arising from the higher third pouch. The relative position of the inferior and superior glands, which are named according to their final location, changes because of the migration of embryological tissues. Hyperparathyroidism and hypoparathyroidism, characterized by alterations in the blood calcium levels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromaffin Cells
Chromaffin cells, also called pheochromocytes (or phaeochromocytes), are neuroendocrine cells found mostly in the medulla of the adrenal glands in mammals. These cells serve a variety of functions such as serving as a response to stress, monitoring carbon dioxide and oxygen concentrations in the body, maintenance of respiration and the regulation of blood pressure. They are in close proximity to pre-synaptic sympathetic ganglia of the sympathetic nervous system, with which they communicate, and structurally they are similar to post-synaptic sympathetic neurons. In order to activate chromaffin cells, the splanchnic nerve of the sympathetic nervous system releases acetylcholine, which then binds to nicotinic acetylcholine receptors on the adrenal medulla. This causes the release of catecholamines. The chromaffin cells release catecholamines: ~80% of adrenaline (epinephrine) and ~20% of noradrenaline (norepinephrine) into systemic circulation for systemic effects on multiple organs ...

Endocrinology
Endocrinology (from '' endocrine'' + '' -ology'') is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones. It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction, and sensory perception caused by hormones. Specializations include behavioral endocrinology and comparative endocrinology. The endocrine system consists of several glands, all in different parts of the body, that secrete hormones directly into the blood rather than into a duct system. Therefore, endocrine glands are regarded as ductless glands. Hormones have many different functions and modes of action; one hormone may have several effects on different target organs, and, conversely, one target orga ...

Theresienstadt
Theresienstadt Ghetto was established by the Schutzstaffel, SS during World War II in the fortress town of Terezín, in the Protectorate of Bohemia and Moravia (German occupation of Czechoslovakia, German-occupied Czechoslovakia). Theresienstadt served as a waystation to the extermination camps. Its conditions were deliberately engineered to hasten the death of its prisoners, and the ghetto also served a propaganda role. Unlike other ghettos, the Forced labor in Nazi Germany, exploitation of forced labor was not economically significant. The ghetto was established by the transportation of Czech Jews in November 1941. The first German Jews, German and Austrian Jews arrived in June 1942; Dutch Jews, Dutch and Danish Jews came at the beginning in 1943, and prisoners of a wide variety of nationalities were sent to Theresienstadt in the last months of the war. About 33,000 people died at Theresienstadt, mostly from malnutrition and disease. More than 88,000 people were held there for ...

Not Available
''Not Available'' is the fourth studio album by American art rock group the Residents, recorded in 1974. The album was allegedly meant to only be released once its creators completely forgot about its existence (adhering to their "Theory of Obscurity," in which an artist's purest work is created without an audience) - however, due to ongoing delays in the release of ''Eskimo'', ''Not Available'' was released to supply the demand for new Residents material, given their unexpected critical and commercial success following the release of the '' Duck Stab'' EP. History It is said that the lyrics and themes of ''Not Available'' arose from personal tensions within the group, and that the project began as a private psychodrama before being adapted into a possible operetta. While the project never took off theatrically, it was still molded into a sort of concept album, taking use of assorted musical ideas, some of them recorded for the group's unfinished film project, ''Vileness Fats.'' ...

19th-century Czech Scientists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
