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.

The church of the Val-de-Grâce, designed by and , 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 care for injured revolutionaries during the French Revolution, and thus the church at was spared much of the desecration and vandalism that plag ...

Scientists From Paris
A scientist is a person who conducts scientific research 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 (circa 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. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar.

History Of Penicillin
The history of penicillin follows a number of observations and discoveries of apparent evidence of antibiotic activity of the mould ''Penicillium'' that led to the development of penicillins that became the most widely used antibiotics. Following the identification of ''Penicillium rubens'' as the source of the compound in 1928 and with the production of pure compound in 1942, penicillin became the first naturally derived antibiotic. There are anecdotes about ancient societies using moulds to treat infections, and in the following centuries many people observed the inhibition of bacterial growth by various moulds. However, it is unknown if the species involved were ''Penicillium'' species or if the antimicrobial substances produced were penicillin. While working at St Mary's Hospital in London, Scottish physician Alexander Fleming was the first to experimentally discover that a ''Penicillium'' mould secretes an antibacterial substance, and the first to concentrate the active sub ...

Tuberculosis
Tuberculosis (TB) is an infectious 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 latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next 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. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active TB is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History By the 2nd century BC, the Ligurian Oxybii established a settlement here known as ''Aegitna'' ( grc, Αἴγιτνα). Historians are unsure what the name means. 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 and the Oxybii. In the 10th century, the town was known as Canua.

Pasteur Institute
The Pasteur Institute (french: Institut Pasteur) 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. Over the years, it has been responsible for discoveries that have enabled medical science to control diseases such as diphtheria, tetanus, tuberculosis, poliomyelitis, influenza, yellow fever, and 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.

Physician
A physician (American English), medical practitioner (Commonwealth English), medical doctor, or simply doctor, is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the ''science'' of medicine—and also a decent competence in its applied practice—the art or ''craft'' of medicine. Both the role of the physician and the meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
