Henrietta Lacks
Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) Note: Some sources report her birthday as August 2, 1920, vs. August 1, 1920. was an African-American woman whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line and one of the most important cell lines in medical research. An immortalized cell line reproduces indefinitely under specific conditions, and the HeLa cell line continues to be a source of invaluable medical data to the present day. Lacks was the unwitting source of these cells from a tumor biopsied during treatment for cervical cancer at Johns Hopkins Hospital in Baltimore, Maryland, U.S., in 1951. These cells were then cultured by George Otto Gey, who created the cell line known as HeLa, which is still used for medical research. As was then the practice, no consent was required to culture the cells obtained from Lacks's treatment. Neither she nor her family were compensated for their extracti ...

George Otto Gey
George Otto Gey ( ; July 6, 1899 – November 8, 1970) was the cell biologist at Johns Hopkins Hospital who is credited with propagating the HeLa cell line from Henrietta Lacks' cervical tumor. He spent over 35 years developing numerous scientific breakthroughs under the Johns Hopkins Medical School and Hospital. Early life and education Gey was born in Pittsburgh, Pennsylvania on July 6, 1899, the son of German immigrants Frank and Emma Gey. He had an older brother and younger sister. Gey's parents immigrated from Germany, and according to the 1910 United States Census, they lived in suburban Pittsburgh. Gey graduated Peabody High School, and received undergraduate degree in biology from the University of Pittsburgh in 1920. He worked as a carpenter and a mason to help pay his way through college. Around 1926, he married Margaret K. (1900–1989), and they later moved to Baltimore where he would earn his medical degree from Johns Hopkins University. Gey was in medical school ...

Pneumoencephalography
Pneumoencephalography (sometimes abbreviated PEG; also referred to as an "air study") was a common medical procedure in which most of the cerebrospinal fluid (CSF) was drained from around the brain by means of a lumbar puncture and replaced with air, oxygen, or helium to allow the structure of the brain to show up more clearly on an X-ray image. It was derived from ventriculography, an earlier and more primitive method where the air is injected through holes drilled in the skull. The procedure was introduced in 1919 by the American neurosurgeon Walter Dandy and was performed extensively until the late 1970s, when it was replaced by more-sophisticated and less-invasive modern neuroimaging techniques. Procedure Though pneumoencephalography was the single most important way of localizing brain lesions of its time, it was, nevertheless, extremely painful and generally not well tolerated by conscious patients. Pneumoencephalography was associated with a wide range of side-effects, inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crownsville Hospital Center
The Crownsville Hospital Center was a psychiatric hospital located in Crownsville, Maryland. It was in operation from 1911 until 2004. History Background Crownsville Hospital Center was enabled by an act of the Maryland General Assembly on April 11, 1910 as the Hospital for the Negro Insane of Maryland. This act also explicitly specified that the facility should not be located in Baltimore. On December 13, 1910, the Board of Managers purchased land which had formerly been farmed for willow and tobacco, located at Crownsville, Maryland, for the sum of $19,000. On May 23, 1910, Dr. Dan Hempeck was designated the first Superintendent. The facility was founded following a 1908 report of "The Maryland State Lunacy Commission" which stated: As early as 1899, the Maryland Lunacy Commission stated in its Annual Report: Again in its 1900 report it stated: In 1888, an article titled "The Need of An Asylum or Hospital for the Separate Care and Treatment of the Colored Insane o ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sparrows Point, Maryland
Sparrow's Point is an unincorporated community in Baltimore County, Maryland, United States, adjacent to Dundalk.

Bethlehem Steel
The Bethlehem Steel Corporation was an American steelmaking company headquartered in Bethlehem, Pennsylvania. For most of the 20th century, it was one of the world's largest steel producing and shipbuilding companies. At the height of its success and productivity, the company was a symbol of American manufacturing leadership in the world, and its decline and ultimate liquidation in the late 20th century is similarly cited as an example of America's diminished manufacturing leadership. From its founding in 1857 through its 2003 dissolution, Bethlehem Steel's headquarters and primary steel mill manufacturing facilities were based in Bethlehem, Pennsylvania in the Lehigh Valley region of the United States. The company's steel was used in the construction of many of America's largest and most famed structures. Among major buildings, Bethlehem produced steel for 28 Liberty Street, the Chrysler Building, the Empire State Building, Madison Square Garden, Rockefeller Center, and the Wa ...

Cerebral Palsy
Cerebral palsy (CP) is a group of movement disorders that appear in early childhood. Signs and symptoms vary among people and over time, but include poor coordination, stiff muscles, weak muscles, and tremors. There may be problems with sensation, vision, hearing, and speaking. Often, babies with cerebral palsy do not roll over, sit, crawl or walk as early as other children of their age. Other symptoms include seizures and problems with thinking or reasoning, which each occur in about one-third of people with CP. While symptoms may get more noticeable over the first few years of life, underlying problems do not worsen over time. Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. Most often, the problems occur during pregnancy, but they may also occur during childbirth or shortly after birth. Often, the cause is unknown. Risk factors include preterm birth, being a twin, certain infections during pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epilepsy
Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. Epileptic seizures can vary from brief and nearly undetectable periods to long periods of vigorous shaking due to abnormal electrical activity in the brain. These episodes can result in physical injuries, either directly such as broken bones or through causing accidents. In epilepsy, seizures tend to recur and may have no immediate underlying cause. Isolated seizures that are provoked by a specific cause such as poisoning are not deemed to represent epilepsy. People with epilepsy may be treated differently in various areas of the world and experience varying degrees of social stigma due to the alarming nature of their symptoms. The underlying mechanism of epileptic seizures is excessive and abnormal neuronal activity in the cortex of the brain which can be observed in the electroencephalogram (EEG) of an individual. The reason this occurs in most cases of epilepsy is u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
