HeLa Cell
HeLa (; also Hela or hela) is an immortalized cell line used in scientific research. It is the oldest and most commonly used human cell line. The line is derived from cervical cancer cells taken on February 8, 1951, named after Henrietta Lacks, a 31-year-old African-American mother of five, who died of cancer on October 4, 1951. The cell line was found to be remarkably durable and prolific, which allows it to be used extensively in scientific study. The cells from Lacks's cancerous cervical tumor were taken without her knowledge or consent, which was common practice in the United States at the time. Cell biologist George Otto Gey found that they could be kept alive, and developed a cell line. Previously, cells cultured from other human cells would only survive for a few days. Cells from Lacks's tumor behaved differently. History Origin In 1951, a patient named Henrietta Lacks was admitted to the Johns Hopkins Hospital with symptoms of irregular vaginal bleeding, and was ...

National Foundation For Infantile Paralysis
March of Dimes is a United States nonprofit organization that works to improve the health of mothers and babies. The organization was founded by President Franklin D. Roosevelt in 1938, as the National Foundation for Infantile Paralysis, to combat polio. The name "March of Dimes" was coined by Eddie Cantor. After funding Jonas Salk's polio vaccine, the organization expanded its focus to the prevention of birth defects and infant mortality. In 2005, as preterm birth emerged as the leading cause of death for children worldwide, research and prevention of premature birth became the organization's primary focus. Organization March of Dimes improves the health of mothers and babies through five programming areas: medical research, education of pregnant women, community programs, government advocacy, and support of pregnant women and mothers. The organization provides women and families with educational resources on baby health, pregnancy, preconception and new motherhood, as well a ...

Poliomyelitis
Poliomyelitis, commonly shortened to polio, is an infectious disease caused by the poliovirus. Approximately 70% of cases are asymptomatic; mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia. These symptoms usually pass within one or two weeks. A less common symptom is permanent paralysis, and possible death in extreme cases.. Years after recovery, post-polio syndrome may occur, with a slow development of muscle weakness similar to that which the person had during the initial infection. Polio occurs naturally only in humans. It is highly infectious, and is spread from person to person either through fecal-oral transmission (e.g. poor hygiene, or by ingestion of food or water contaminated by human feces), or via the oral-oral route. Those who are infected may spread the disease for up to six weeks even if no symptoms are present. The disease may be diagnosed by ...

Polio Vaccine
Polio vaccines are vaccines used to prevent poliomyelitis (polio). Two types are used: an inactivated poliovirus given by injection (IPV) and a weakened poliovirus given by mouth (OPV). The World Health Organization (WHO) recommends all children be fully vaccinated against polio. The two vaccines have eliminated polio from most of the world, and reduced the number of cases reported each year from an estimated 350,000 in 1988 to 33 in 2018. The inactivated polio vaccines are very safe. Mild redness or pain may occur at the site of injection. Oral polio vaccines cause about three cases of vaccine-associated paralytic poliomyelitis per million doses given. This compares with 5,000 cases per million who are paralysed following a polio infection. Both types of vaccine are generally safe to give during pregnancy and in those who have HIV/AIDS but are otherwise well. However, the emergence of circulating vaccine-derived poliovirus (cVDPV), a form of the vaccine virus that has rever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jonas Salk
Jonas Edward Salk (; born Jonas Salk; October 28, 1914June 23, 1995) was an American virologist and medical researcher who developed one of the first successful polio vaccines. He was born in New York City and attended the City College of New York and New York University School of Medicine. In 1947, Salk accepted a professorship in the School of Medicine at the University of Pittsburgh. It was there that he undertook a project to determine the number of different types of poliovirus, starting in 1948. For the next seven years, Salk devoted himself towards developing a vaccine against polio. Salk was immediately hailed as a "miracle worker" when the vaccine's success was first made public in April 1955, and chose to not patent the vaccine or seek any profit from it in order to maximize its global distribution. The National Foundation for Infantile Paralysis and the University of Pittsburgh looked into patenting the vaccine but, since Salk's techniques were not novel, their paten ...

Baltimore City Paper
''Baltimore City Paper'' was a free alternative weekly newspaper published in Baltimore, Maryland, founded in 1977 by Russ Smith and Alan Hirsch.

It was distributed on Wednesdays in distinctive yellow boxes found throughout the Baltimore area. The paper folded in 2017, due to the collapse of advertising revenue income to print media. The Media Group's closure announcement happened at the same meeting immediately after recognizing ''City Paper'' staff joining the Washington-Baltimore News Guild. History Russ Smith and Alan Hirsch started the Baltimore City Paper in May 1977 while students at Johns Hopkins University. It was originally named the ''City Squeeze'', and Smith and Hirsch published it using the offices of the Johns Hopkins student newspaper. In 1978, they took the paper out of the university and sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Common Rule
The Common Rule is a 1981 rule of ethics in the United States regarding biomedical and behavioral research involving human subjects. A significant revision became effective July 2018. It governed Institutional Review Boards for oversight of human research and followed the 1975 revision of the Declaration of Helsinki; it is encapsulated in the 1991 revision to the U.S. Department of Health and Human Services Title 45 CFR 46 (Public Welfare) Subparts A, B, C and D. Subpart A. The Common Rule is the baseline standard of ethics by which any government-funded research in the US is held; nearly all U.S. academic institutions hold their researchers to these statements of rights regardless of funding. Background The Common Rule is a 1981 rule of ethics (revised in 2018) regarding biomedical and behavioral research involving human subjects in the United States. The regulations governing Institutional Review Boards for oversight of human research followed the 1975 revision of the Declara ...
