François Jacob
François Jacob (17 June 1920 – 19 April 2013) was a French biologist who, together with Jacques Monod, originated the idea that control of enzyme levels in all cells occurs through regulation of transcription. He shared the 1965 Nobel Prize in Medicine with Jacques Monod and André Lwoff. Early years Jacob was born the only child of Simon, a merchant, and Thérèse (Franck) Jacob, in Nancy, France. An inquisitive child, he learned to read at a young age. Albert Franck, Jacob's maternal grandfather, a four-star general, was Jacob's childhood role model. At seven he entered the Lycée Carnot, where he was schooled for the next ten years; in his autobiography he describes his impression of it: "a cage". He was antagonized by rightist youth at the Lycée Carnot around 1934. He describes his father as a "conformist in religion", while his mother and other family members important in his childhood were secular Jews; shortly after his bar mitzvah he became an atheist.

Nancy, France
Nancy ; Lorraine Franconian: ''Nanzisch'' is the prefecture of the northeastern French department of Meurthe-et-Moselle. It was the capital of the Duchy of Lorraine, which was annexed by France under King Louis XV in 1766 and replaced by a province, with Nancy maintained as capital. Following its rise to prominence in the Age of Enlightenment, it was nicknamed the "capital of Eastern France" in the late 19th century. The metropolitan area of Nancy had a population of 511,257 inhabitants at the 2018 census, making it the 16th-largest functional urban area in France and Lorraine's largest. The population of the city of Nancy proper is 104,885. The motto of the city is , —a reference to the thistle, which is a symbol of Lorraine. Place Stanislas, a large square built between 1752 and 1756 by architect Emmanuel Héré under the direction of Stanislaus I of Poland to link the medieval old town of Nancy and the new city built under Charles III, Duke of Lorraine in the 17th ...

Lycée Carnot
The Lycée Carnot is a public secondary and higher education school at 145 Boulevard Malesherbes in the 17th arrondissement, Paris, France. The Lycée Carnot was founded in 1869, first bearing the name of École Monge and then renamed in 1895. Some of its former students have been among the most-influential personalities in the country, including Jacques Chirac, the former French President, and Pascal Lamy, the former president of the World Trade Organization since (2005–2013). The Orthodox theologian Fr. Alexander Schmemann attended the school. Daft Punk musicians Thomas Bangalter and Guy-Manuel de Homem-Christo met there in 1987. The poet Louis Aragon also attended Carnot. The Lycée has served as a filming location for many films, and often hosts fashion shows during Paris fashion week. The heart of the building is a large hall measuring 80 by 30 meters covered with a glass roof mounted on a metal frame on a project by Gustave Eiffel. The Lycée Carnot has a middle school ...

Developmental Biology
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration, asexual reproduction, metamorphosis, and the growth and differentiation of stem cells in the adult organism. Perspectives The main processes involved in the embryonic development of animals are: tissue patterning (via regional specification and patterned cell differentiation); tissue growth; and tissue morphogenesis. * Regional specification refers to the processes that create the spatial patterns in a ball or sheet of initially similar cells. This generally involves the action of cytoplasmic determinants, located within parts of the fertilized egg, and of inductive signals emitted from signaling centers in the embryo. The early stages of regional specification do not generate functional differentiated cells, but cell populations committed to developing to a specific region or part of the organism. These a ...

Gene Expression
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce end products, protein or non-coding RNA, and ultimately affect a phenotype, as the final effect. These products are often proteins, but in non-protein-coding genes such as transfer RNA (tRNA) and small nuclear RNA (snRNA), the product is a functional non-coding RNA. Gene expression is summarized in the central dogma of molecular biology first formulated by Francis Crick in 1958, further developed in his 1970 article, and expanded by the subsequent discoveries of reverse transcription and RNA replication. The process of gene expression is used by all known life— eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea), and utilized by viruses—to generate the macromolecular machinery for life. In genetics, gene expression is the most fundamental level at which the genotype gives rise to the phenot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacteriology
Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species. Because of the similarity of thinking and working with microorganisms other than bacteria, such as protozoa, fungi, and viruses, there has been a tendency for the field of bacteriology to extend as microbiology. The terms were formerly often used interchangeably. However, bacteriology can be classified as a distinct science. Overview Definition Bacteriology is the study of bacteria and their relation to medicine. Bacteriology evolved from physicians needing to apply the germ theory to address the concerns relating to disease spreading in hospitals the 19th century. Identification and characterizing of bacteria being associated to diseases led to advances in pathogenic bacteriology. K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyrothricin
Tyrothricin is an antibiotic mixture which was isolated from '' Bacillus brevis'' by Rene Dubos in the late 1930s. It was later shown by Dubos and Rollin Hotchkiss to be a mixture of two different antibiotics: gramicidin and tyrocidine. Both gramicidin and tyrocidine are short polypeptides which disrupt the cell membranes of some, primarily Gram-positive, bacteria. Tyrothricin and its component antibiotics are too toxic to be taken internally but are sometimes used as topical antibiotics. Tyrothricin, and its component antibiotics, belongs to the pharmacologically related group of polypeptide antibiotic compounds including colistin, polymyxin B, and bacitracin Bacitracin is a polypeptide antibiotic. It is a mixture of related cyclic peptides produced by ''Bacillus licheniformis'' bacteria, that was first isolated from the variety "Tracy I" ( ATCC 10716) in 1945. These peptides disrupt Gram-positive bac .... There is no cross-resistance to these three agents. References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Croix De Guerre 1939–1945
The ''Croix de Guerre 1939–1945'' (English: War Cross 1939–1945) is a French military decoration, a version of the '' Croix de Guerre'' created on 26 September 1939 to honour people who fought with the Allies against the Axis forces at any time during World War II. After Germany invaded and overran mainland France in the Battle of France in May and June 1940, this ''Croix de Guerre'' was replaced by the pro-Axis Vichy French government with another ''Croix'' with a black-and-green ribbon, while the original was upheld by Free France. Since the triumph of the Free French side in World War II, this version is the only one officially recognized by the French government. Award statute Due to the large extent of the war zone, recipients included those who fought during, with, at, or in the following: * Battle of France * French Forces of the Interior * Free French Forces * Western Front * Middle East Theater * Mediterranean Theater * African campaigns Award description Med ...

Légion D'honneur
The National Order of the Legion of Honour (french: Ordre national de la Légion d'honneur), formerly the Royal Order of the Legion of Honour ('), is the highest French order of merit, both military and civil. Established in 1802 by Napoleon Bonaparte, it has been retained (with occasional slight alterations) by all later French governments and regimes. The order's motto is ' ("Honour and Fatherland"); its seat is the Palais de la Légion d'Honneur next to the Musée d'Orsay, on the left bank of the Seine in Paris. The order is divided into five degrees of increasing distinction: ' (Knight), ' (Officer), ' ( Commander), ' (Grand Officer) and ' (Grand Cross). History Consulate During the French Revolution, all of the French orders of chivalry were abolished and replaced with Weapons of Honour. It was the wish of Napoleon Bonaparte, the First Consul, to create a reward to commend civilians and soldiers. From this wish was instituted a , a body of men that was not an or ...

Ordre De La Libération
The Order of Liberation (french: Ordre de la Libération) is a French Order which was awarded to heroes of the Liberation of France during World War II. It is a very high honour, second only after the ''Légion d’Honneur'' (Legion of Honour). Very few people, military units and communes were ever awarded it; and only for their deeds during World War II. A different order, the ''Médaille de la Résistance'' ("Resistance Medal"), was created and awarded for lesser but still distinguished deeds by members of the Resistance. History The ''Order of Liberation'' was established by General de Gaulle in order n° 7, signed on 16 November 1940 in Brazzaville, the capital of '' France Libre'' from 1940 to 1943. The object of the Order was to "reward people, of the military or civilian communities, who will have distinguished themselves in the task of liberating France and her Empire". There were no restrictions as to age, sex, rank, origin or nationality; nor any regarding the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liberation Of France
The liberation of France in the Second World War was accomplished through diplomacy, politics and the combined military efforts of the Allied Powers, Free French forces in London and Africa, as well as the French Resistance. Nazi Germany invaded France in May 1940. Their rapid advance through the undefended Ardennes caused a crisis in the French government; the French Third Republic dissolved itself in July, and handed over absolute power to Marshal Philippe Pétain, an elderly hero of World War I. Pétain signed an armistice with Germany with the north and west of France under German military occupation. Pétain, charged with calling a Constitutional Authority, instead established an authoritarian government in the spa town of Vichy, in the southern '' zone libre'' ("free zone"). Though nominally independent, Vichy France became a collaborationist regime and was little more than a Nazi client state that actively participated in Jewish deportations. Even before France s ...

2nd Armored Division (France)
The French 2nd Armored Division (french: link=no, 2e Division Blindée, 2e DB), commanded by General Philippe Leclerc, fought during the final phases of World War II in the Western Front for the liberation of France. The division was formed around a core of units that had fought in the North African campaign, and re-organized into a light armored division in 1943. The division embarked in April 1944 and shipped to various ports in Britain. On 29 July 1944, bound for France, the division embarked at Southampton. During combat in 1944, the division liberated Paris, defeated a Panzer brigade during the armored clashes in Lorraine, forced the Saverne Gap and liberated Strasbourg. After taking part in the Battle of the Colmar Pocket, the division was moved west and assaulted the German-held Atlantic port of Royan, before recrossing France in April 1945 and participating in the final fighting in southern Germany, even going first into Hitler's "Eagle's Nest" (Americans captured th ...
