Evelyn M. Witkin
Evelyn M. Witkin (born Evelyn Maisel; March 9, 1921) is an American geneticist who was awarded the National Medal of Science for her work on DNA mutagenesis and DNA repair. Research In 1944, Witkin spent the summer at Cold Spring Harbor Laboratory (CSHL). During her stay she isolated a UV radiation-resistant mutant of ''E. coli''; this was the first time mutations conferring UV radiation-resistance were isolated. She returned to CSHL in 1945 and stayed there to complete her PhD research; her degree was conferred in 1947 and was employed by the Carnegie Institution to continue work at CSHL until 1955. Witkin then worked at the State University of New York's Downstate Medical Center in Brooklyn until 1971. Witkin was appointed Professor of Biological Sciences at Douglass College, Rutgers University in 1971 and was named Barbara McClintock Professor of Genetics in 1979, and then moved to the Waksman Institute at Rutgers in 1983. Witkin's research since the completion of her PhD wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Columbia University
Columbia University (also known as Columbia, and officially as Columbia University in the City of New York) is a private research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhattan, Columbia is the oldest institution of higher education in New York and the fifth-oldest institution of higher learning in the United States. It is one of nine colonial colleges founded prior to the Declaration of Independence. It is a member of the Ivy League. Columbia is ranked among the top universities in the world. Columbia was established by royal charter under George II of Great Britain. It was renamed Columbia College in 1784 following the American Revolution, and in 1787 was placed under a private board of trustees headed by former students Alexander Hamilton and John Jay. In 1896, the campus was moved to its current location in Morningside Heights and renamed Columbia University. Columbia scientists and scholars have ...

SOS Response
The SOS response is a global response to DNA damage in which the cell cycle is arrested and DNA repair and mutagenesis is induced. The system involves the RecA protein ( Rad51 in eukaryotes). The RecA protein, stimulated by single-stranded DNA, is involved in the inactivation of the repressor (LexA) of SOS response genes thereby inducing the response. It is an error-prone repair system that contributes significantly to DNA changes observed in a wide range of species. Discovery The SOS response was discovered and named by Miroslav Radman in 1975. Mechanism During normal growth, the SOS genes are negatively regulated by LexA repressor protein dimers. Under normal conditions, LexA binds to a 20-bp consensus sequence (the SOS box) in the operator region for those genes. Some of these SOS genes are expressed at certain levels even in the repressed state, according to the affinity of LexA for their SOS box. Activation of the SOS genes occurs after DNA damage by the accumulation of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centenarian
A centenarian is a person who has reached the age of 100 years. Because life expectancies worldwide are below 100 years, the term is invariably associated with longevity. In 2012, the United Nations estimated that there were 316,600 living centenarians worldwide. As world population and life expectancy continue to increase, the number of centenarians is expected to increase substantially in the 21st century. According to the UK ONS, one-third of babies born in 2013 in the UK are expected to live to 100. The United Nations predicts that there are 573,000 centenarians currently, almost quadruple the 151,000 suggested in the year 2000. According to a 1998 United Nations demographic survey, Japan is expected to have 272,000 centenarians by 2050; other sources suggest that the number could be closer to 1 million. The incidence of centenarians in Japan was one per 3,522 people in 2008. In Japan, the number of centenarians is highly skewed towards females. Japan in fiscal year 2016 ...

Sha Na Na
Sha Na Na was an American rock and roll doo-wop group. Formed in 1969, but performing a song-and-dance repertoire based on 1950s hit songs, it simultaneously revived and parodied the music and the New York street culture of the 1950s. After gaining initial fame for their performance at Woodstock, made possible with the help of their friend Jimi Hendrix, the group hosted ''Sha Na Na'', a syndicated variety series that ran from 1977 to 1981. Billing themselves as "from the streets of New York", members were frequently outfitted in gold lamé or leather jackets and sported pompadour or ducktail hairdos. The group's name was taken from a series of nonsense syllables ("Sha Na Na Na Sha Na Na Na Na") in the song " Get a Job", originally recorded by the Silhouettes. The final lineup featured original members Donny York and Jocko Marcellino, and longtime member Screamin' Scott Simon, who joined in 1970. Everyone else from the original band and TV show had since departed. Fina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Forward
''The Forward'' ( yi, פֿאָרווערטס, Forverts), formerly known as ''The Jewish Daily Forward'', is an American news media organization for a Jewish American audience. Founded in 1897 as a Yiddish-language daily socialist newspaper, ''The New York Times'' reported that Seth Lipsky "started an English-language offshoot of the Yiddish-language newspaper" as a weekly newspaper in 1990. In the 21st century ''The Forward'' is a digital publication with online reporting. In 2016, the publication of the Yiddish version changed its print format from a biweekly newspaper to a monthly magazine; the English weekly paper followed suit in 2017. Those magazines were published until 2019. ''The Forward''s perspective on world and national news and its reporting on the Jewish perspective on modern United States have made it one of the most influential American Jewish publications. It is published by an independent nonprofit association. It has a politically progressive editorial fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephen J
Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( grc-gre, Στέφανος ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or "protomartyr") of the Christian Church. In English, Stephen is most commonly pronounced as ' (). The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. The spelling as Stephen can also be pronounced which is from the Greek original version, Stephanos. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ; related names that have found some c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
