Ernest Duchesne
Ernest Duchesne (30 May 1874 – 12 April 1912) was a French physician who noted that certain molds kill bacteria. He made this discovery 32 years before Alexander Fleming discovered the antibiotic properties of penicillin, a substance derived from those molds, but his research went unnoticed. Life and work Duchesne entered ''l'Ecole du Service de Santé Militaire de Lyon'' (the Military Health Service School of Lyons) in 1894.

Pasteur Institute
The Pasteur Institute (, ) is a French non-profit private foundation dedicated to the study of biology, micro-organisms, diseases, and vaccines. It is named after Louis Pasteur, who invented pasteurization and vaccines for anthrax and rabies. The institute was founded on 4 June 1887 and inaugurated on 14 November 1888. For over a century, the Institut Pasteur has researched infectious diseases. This worldwide biomedical research organization based in Paris was the first to isolate HIV, the virus that causes AIDS, in 1983. It has also been responsible for discoveries that have enabled medical science to control diseases such as diphtheria, tetanus, tuberculosis, poliomyelitis, influenza, yellow fever, and Plague (disease), plague. Since 1908, ten Institut Pasteur scientists have been awarded the Nobel Prize for medicine and physiology—the 2008 Nobel Prize in Physiology or Medicine was shared between two Pasteur scientists.

Scientists From Paris
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Penicillin
The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mould ''Penicillium'' that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first naturally-derived antibiotic. Ancient societies used moulds to treat infections, and in the following centuries many people observed the inhibition of bacterial growth by moulds. While working at St Mary's Hospital in London in 1928, Scottish physician Alexander Fleming was the first to experimentally determine that a ''Penicillium'' mould secretes an antibacterial substance, which he named "penicillin". The mould was found to be a variant of '' Penicillium notatum'' (now called '' Penicillium rubens''), a contaminant of a bacterial culture in his laboratory. The work on penicillin at St Mary's ended in 1929. In 1939, a team of scientists at the Sir William Dunn School of Patho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuberculosis
Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, is a contagious disease usually caused by ''Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as inactive or latent tuberculosis. A small proportion of latent infections progress to active disease that, if left untreated, can be fatal. Typical symptoms of active TB are chronic cough with hemoptysis, blood-containing sputum, mucus, fever, night sweats, and weight loss. Infection of other organs can cause a wide range of symptoms. Tuberculosis is Human-to-human transmission, spread from one person to the next Airborne disease, through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with latent TB do not spread the disease. A latent infection is more likely to become active in those with weakened I ...

Cannes
Cannes (, ; , ; ) is a city located on the French Riviera. It is a communes of France, commune located in the Alpes-Maritimes departments of France, department, and host city of the annual Cannes Film Festival, Midem, and Cannes Lions International Festival of Creativity. The city is known for its association with the rich and famous, its luxury hotels and restaurants, and for several conferences. History By the 2nd century BC, the Ligurian Oxybii established a settlement here known as ''Aegitna'' (). Historians are unsure what the name means, but the connection to Greek αἴγες "waves, surf" seems evident. The second element could be compared to the Cretan and Thessalian towns of Itanos () and Iton (); also phonetically close is the Aetolian town of Aegitium (). The area was a fishing village used as a port of call between the Lérins Islands. In 154 Before Christ, BC, it became the scene of violent but quick conflict between the troops of Quintus Opimius (consul), Quintus ...

Val-de-Grâce
The Val-de-Grâce (; Hôpital d'instruction des armées du Val-de-Grâce or HIA Val-de-Grâce) was a military hospital located at 74 boulevard de Port-Royal in the 5th arrondissement of Paris, France. It was closed as a hospital in 2016. History The church of the Val-de-Grâce was built by order of Queen Anne of Austria, wife of Louis XIII. After the birth of her son Louis XIV after 23 years of childless marriage, Anne showed her gratitude to the Virgin Mary by building a church on the land of a Benedictine convent. Louis XIV is said to have laid the cornerstone for the Val-de-Grâce in a ceremony that took place 1 April 1645, when he was seven years old. The church of the Val-de-Grâce, designed by François Mansart and Jacques Lemercier, is considered by some as Paris's best example of baroque architecture (curving lines, elaborate ornamentation, and harmony of different elements). Construction began in 1645 and was completed in 1667. The Benedictine nuns provided medical ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guinea Pigs
The guinea pig or domestic guinea pig (''Cavia porcellus''), also known as the cavy or domestic cavy ( ), is a species of rodent belonging to the genus ''Cavia'', family Caviidae. Breeders tend to use the name "cavy" for the animal, but "guinea pig" is more commonly used in scientific and laboratory contexts. Despite their name, guinea pigs are not native to Guinea, nor are they closely related to pigs. Instead, they originated in the Andes region of South America, where wild guinea pigs can still be found today. Studies based on biochemistry and DNA hybridization suggest they are domesticated animals that do not exist naturally in the wild, but are descendants of a closely related cavy species such as '' C. tschudii''. Originally, they were domesticated as livestock (source of meat) in the Andean region and are still consumed in some parts of the world. In Western society, the guinea pig has enjoyed widespread popularity as a pet since its introduction to Europe and No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
