Oswald T. Avery
Oswald Theodore Avery Jr. (October 21, 1877 – February 20, 1955) was a Canadian-American physician and medical researcher. The major part of his career was spent at the Rockefeller Hospital in New York City. Avery was one of the first molecular biologists and a pioneer in immunochemistry, but he is best known for the experiment (published in 1944 with his co-workers Colin MacLeod and Maclyn McCarty) that isolated DNA as the material of which genes and chromosomes are made. The Nobel laureate Arne Tiselius said that Avery was the most deserving scientist not to receive the Nobel Prize for his work, though he was nominated for the award throughout the 1930s, 1940s, and 1950s. The lunar crater Avery was named in his honor. Early life and education Avery was born in Halifax, Nova Scotia in 1877 to Francis Joseph Avery, a Baptist minister, and his wife Elizabeth Crowdy. The couple had immigrated from Britain in 1873. Oswald Avery was born and grew up in a small wooden row ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fellowship Of The Royal Society
Fellowship of the Royal Society (FRS, ForMemRS and HonFRS) is an award granted by the judges of the Royal Society of London to individuals who have made a "substantial contribution to the improvement of natural knowledge, including mathematics, engineering science, and medical science".

Arne Tiselius
Arne Wilhelm Kaurin Tiselius (10 August 1902 – 29 October 1971) was a Swedish biochemist who won the Nobel Prize in Chemistry in 1948 "for his research on electrophoresis and adsorption analysis, especially for his discoveries concerning the complex nature of the serum proteins." Education Tiselius was born in Stockholm. Following the death of his father, the family moved to Gothenburg where he went to school, and after graduation at the local "Realgymnasium" in 1921, he studied at the Uppsala University, specializing in chemistry. Career and research Tiselius became a research assistant at Theodor Svedberg's laboratory in 1925 and obtained his doctoral degree in 1930 on the moving-boundary method of studying the electrophoresis of proteins. From then to 1935 he published a number of papers on diffusion and adsorption in naturally occurring base-exchanging zeolites, and these studies continued during a year's visit to Hugh Stott Taylor's laboratory in Princeton Universit ...

Bacterium
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1918 Influenza Epidemic
The 1918–1920 influenza pandemic, commonly known by the misnomer Spanish flu or as the Great Influenza epidemic, was an exceptionally deadly global influenza pandemic caused by the H1N1 influenza A virus. The earliest documented case was March 1918 in Kansas, United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected in four successive waves. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it one of the deadliest pandemics in history. The pandemic broke out near the end of World War I, when wartime censors suppressed bad news in the belligerent countries to maintain morale, but newspapers freely reported the outbreak in neutral Spain, creating a false impression of Spain as the epicenter and leading to the "Spanish flu" misnomer. Limited historical epidemiological da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumonia
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system. ...

Streptococcus Pneumoniae
''Streptococcus pneumoniae'', or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic (under aerobic conditions) or beta-hemolytic (under anaerobic conditions), aerotolerant anaerobic member of the genus Streptococcus. They are usually found in pairs (diplococci) and do not form spores and are non motile. As a significant human pathogenic bacterium ''S. pneumoniae'' was recognized as a major cause of pneumonia in the late 19th century, and is the subject of many humoral immunity studies. ''Streptococcus pneumoniae'' resides asymptomatically in healthy carriers typically colonizing the respiratory tract, sinuses, and nasal cavity. However, in susceptible individuals with weaker immune systems, such as the elderly and young children, the bacterium may become pathogenic and spread to other locations to cause disease. It spreads by direct person-to-person contact via respiratory droplets and by auto inoculation in persons carrying the bacteria in their upper r ...

Alphonse Dochez
Alphonse Raymond Dochez (April 21, 1882 – June 30, 1964) was an American physician and microbiologist. His research focused on infectious diseases, including scarlet fever, the common cold, and pneumococcal pneumonia. Dochez is credited with developing the first effective treatment for scarlet fever. His work also established viruses as the cause of the common cold. Early life and education Dochez was born in San Francisco to Louis and Josephine Dietrich Dochez. His family is of Belgian descent. Dochez moved to Indianapolis as a young child, then later to Harford County, Maryland, Harford County, Maryland. His parents operated a farm, and he developed a strong interest in hunting and fishing. Dochez received a B.A. from Johns Hopkins University in 1903, and an M.D. in 1907. Career After graduation, Dochez worked at the laboratory of pathology at Hopkins investigating the effects of iodine-free diets on animals. After one year, he applied to work at the Rockefeller Univer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North End, Halifax
The North End of Halifax is a neighbourhood of Halifax, Nova Scotia occupying the northern part of Halifax Peninsula immediately north of Downtown Halifax. History Prior to European colonization, the Mi'kmaq inhabited the land throughout Atlantic Canada and Northern Maine. The North End of Halifax began as an agricultural expansion north from central Halifax as African American and German Foreign Protestant settlers arrived in the province. It became the focus of industry in Halifax with the construction of the Nova Scotia Railway in the 1850s which located its terminal in the North End. Factories such as the Nova Scotia Cotton Manufacturing Company, Hillis & Sons Foundry, and the Acadia Sugar Refinery, made the North End the focus of manufacturing in Halifax. Railway growth intensified with the extension of railways further into the North End and construction of the North Street Station in 1878, the largest station east of Montreal.
