List Of Nobel Laureates In Physiology Or Medicine
The Nobel Prize in Physiology or Medicine () is awarded annually by the Swedish Karolinska Institute to scientists in the various fields of physiology or medicine. It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel (who died in 1896), awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members and an executive secretary elected by the Karolinska Institute. While commonly referred to as the Nobel Prize in Medicine, Nobel specifically stated that the prize be awarded for "physiology or medicine" in his will. Because of this, the prize can be awarded in a broader range of fields. The first Nobel Prize in Physiology or Medicine was awarded in 1901 to Emil Adolf von Behring, of Germany. Each recipient receives a medal, a diploma and a monetary award that has varied t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Signal Transduction
Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a biochemical cascade, series of molecular events. Proteins responsible for detecting stimuli are generally termed receptor (biology), receptors, although in some cases the term sensor is used. The changes elicited by ligand (biochemistry), ligand binding (or signal sensing) in a receptor give rise to a biochemical cascade, which is a chain of biochemical events known as a Cell signaling#Signaling pathways, signaling pathway. When signaling pathways interact with one another they form networks, which allow cellular responses to be coordinated, often by combinatorial signaling events. At the molecular level, such responses include changes in the transcription (biology), transcription or translation (biology), translation of genes, and post-translational modification, post-translational and conformational changes in proteins, as well as changes in their location. These molecula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Adelbert Doisy
Edward Adelbert Doisy (November 13, 1893 – October 23, 1986) was an American biochemist. He received the Nobel Prize in Physiology or Medicine in 1943 with Henrik Dam for their discovery of vitamin K (K from "Koagulations-Vitamin" in German) and its chemical structure. Doisy was born in Hume, Illinois, on November 13, 1893. He completed his A.B. degree in 1914 and his M.S. degree in 1916 from the University of Illinois at Urbana-Champaign. He completed his Ph.D. in 1920 from Harvard University. In 1919 he accepted a faculty appointment in the Department of Biochemistry at Washington University School of Medicine, where he rose in rank to associate professor. In 1923, he moved to Saint Louis University as professor and chairman of the new Department of Biochemistry. He served as professor and chairman of that department until he retired in 1965. Saint Louis University renamed the department the E.A. Doisy Department of Biochemistry, in his honor. More recently, the department ha ...

Henrik Dam
Carl Peter Henrik Dam (21 February 1895 – 17 April 1976) was a Danish biochemist and physiologist. He was awarded the Nobel Prize in Medicine in 1943 for joint work with Edward Doisy in discovering vitamin K and its role in human physiology. Dam's key experiment involved feeding a cholesterol-free diet to chickens. He initially replicated experiments reported by scientists at the Ontario Agricultural College (OAC). McFarlane, Graham and Richardson, working on the chick feed program at OAC, had used chloroform to remove all fat from chick chow. They noticed that chicks fed only fat-depleted chow developed hemorrhages and started bleeding from tag sites. Dam found that these defects could not be restored by adding purified cholesterol to the diet. It appeared that—together with the cholesterol—a second compound had been extracted from the food, and this compound was called the coagulation vitamin. The new vitamin received the letter K because the initial discoveries were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corneille Heymans
Corneille Jean François Heymans (28 March 1892 – 18 July 1968) was a Belgian physiologist. He studied at the Jesuit College of Saint Barbara and then at Ghent University, where he obtained a doctor's degree in 1920. Heymans won the Nobel Prize for Physiology or Medicine in 1938 for showing how blood pressure and the oxygen content of the blood are measured by the body and transmitted to the brain. Early life and education After graduation Heymans worked at the Collège de France (under Prof. E. Gley), the University of Lausanne (under Prof. M. Arthus), the University of Vienna (under Prof. H. H. Meyer), University College London (under Prof. E. H. Starling) and Case Western Reserve University School of Medicine (under Prof. C. F. Wiggers). In 1922 Heymans became lecturer in Pharmacodynamics at Ghent University, and in 1930 succeeded his father, Jean-François Heymans, as Professor of Pharmacology, as well as being appointed Head of the Department of Pharmacology, Pharmaco ...

Johannes Fibiger
Johannes Andreas Grib Fibiger (23 April 1867 – 30 January 1928) was a Danish physician and professor of anatomical pathology at the University of Copenhagen. He was the recipient of the 1926 Nobel Prize in Physiology or Medicine "for his discovery of the ''Spiroptera carcinoma''". He claimed to have shown that the roundworm which he called ''Spiroptera carcinoma'' (but is correctly named '' Gongylonema neoplasticum'') could cause stomach cancer ( squamous cell carcinoma) in rats and mice. His experimental results were later proven to be a case of mistaken conclusion. While working at the Institute of Pathological Anatomy of University of Copenhagen, Fibiger discovered new roundworms in 1907 from wild rats. He suspected that the roundworms were responsible for stomach cancer in those rats. In 1913, he reported that he could experimentally induce cancer in healthy rats using the roundworms. His discovery was considered "the greatest contribution to experimental medicine" at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Fritz Meyerhof
Otto Fritz Meyerhof (; 12 April 1884 – 6 October 1951) was a German physician and biochemist who won the 1922 Nobel Prize in Physiology and Medicine. Biography Otto Fritz Meyerhof was born in Hannover, at Theaterplatz 16A (now:Rathenaustrasse 16A), the son of wealthy Jewish parents. In 1888, his family moved to Berlin, where Otto spent most of his childhood, and where he started his study of medicine. He continued these studies in Strasbourg and Heidelberg, from which he graduated in 1909, with a work titled "Contributions to the Psychological Theory of Mental Illness". In Heidelberg, he met Hedwig Schallenberg. They married in 1914 and had three children together: a daughter, Bettina, and two sons, Gottfried (who after emigration used the anglicized name Geoffrey) and Walter. In 1912, Otto Meyerhof moved to the University of Kiel, where he received a professorship in 1918.

Archibald Hill
Archibald Vivian Hill (26 September 1886 – 3 June 1977), better known to friends and colleagues as A. V. Hill, was a British physiologist, one of the founders of the diverse disciplines of biophysics and operations research. He shared the 1922 Nobel Prize in Physiology or Medicine for his elucidation of the production of heat and mechanical work in muscles. Biography Born in Bristol, he was educated at Blundell's School and graduated from Trinity College, Cambridge as third wrangler in the mathematics tripos before turning to physiology. While still an undergraduate at Trinity College, he derived in 1909 what came to be known as the Langmuir equation. This is closely related to Michaelis–Menten kinetics. In this paper, Hill's first publication, he derived both the equilibrium form of the Langmuir equation, and also the exponential approach to equilibrium. The paper, written under the supervision of John Newport Langley, is a landmark in the history of receptor theory, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Bárány
Robert Bárány (, ; 22 April 1876 – 8 April 1936) was an Austrian-born otologist. He received the 1914 Nobel Prize in Physiology or Medicine for his work on the physiology and pathology of the vestibular apparatus. Life and career Bárány was born in Vienna, Austria-Hungary. He was the eldest of six children of Maria (née Hock), the daughter of a scientist, and Ignác Bárány, born 1842 in Várpalota, Kingdom of Hungary, who was a bank official and estate manager. His father was a Hungarian Jew whose father also was named Ignác Bárány ( Bárány Ignác). He attended medical school at Vienna University, graduating in 1900. As a doctor in Vienna, Bárány was syringing fluid into the external auditory canal of a patient to relieve the patient's dizzy spells. The patient experienced vertigo and nystagmus (involuntary eye movement) when Bárány injected fluid that was too cold. In response, Bárány warmed the fluid for the patient and the patient experienced nystagmu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerty Cori
Gerty Theresa Cori (; August 15, 1896 – October 26, 1957) was a Bohemian-Austrian and American biochemist who in 1947 was the third woman to win a Nobel Prize in science, and the first woman to be awarded the Nobel Prize in Physiology or Medicine, for her role in the "discovery of the course of the catalytic conversion of glycogen". Cori was born in Prague, the capital of Bohemia within the Austro-Hungarian Empire. Growing up at a time when women were marginalized and allowed few educational opportunities, she gained admittance to medical school, where she met her future husband Carl Ferdinand Cori in an anatomy class. Upon their graduation in 1920, they married. Because of deteriorating conditions in Europe, the couple emigrated to the United States in 1922. Gerty Cori continued her early interest in medical research, collaborating in the laboratory with Carl. She published research coauthored with her husband, as well as publishing singly. Unlike her husband, she had diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerhard Domagk
Gerhard Johannes Paul Domagk (; 30 October 1895 – 24 April 1964) was a German pathologist and bacteriologist. He is credited with the discovery of Sulfonamide (medicine), sulfonamidochrysoidine (KL730) as an antibiotic for which he received the 1939 Nobel Prize in Physiology or Medicine. The drug became the first commercially available antibiotic and marketed under the brand name Prontosil. While working in the pathology department of the University of Münster, Domagk was invited to join the IG Farben branch at Elberfeld (later Wuppertal) in 1927. His duty was to test chemical compounds prepared at the IG Farben laboratory for potential drugs. A novel compound synthesised by Friedrich Mietzsch and Joseph Klarer, a benzene derivative of azo dye attached with sulphonamide group as a side chain was found to have antibacterial activity against human bacterium ''Streptococcus pyogenes.'' In 1935, Domagk's only daughter, Hildegarde, injured herself and contracted a streptococcal in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metabolism
Metabolism (, from ''metabolē'', "change") is the set of life-sustaining chemical reactions in organisms. The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their Structures#Biological, structures, and respond to their environments. The word ''metabolism'' can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transportation of substances into and between different cells, in which case the above described set of reactions within the cells is called intermediary (or intermediate) metabolism. Metabolic reactions may be categorized as ''catabolic''—the ''breaking down'' of compounds (for example, of glucose to pyruvate by c ...
