Mary Ellen Jones (chemist)
Mary Ellen Jones (December 25, 1922 – August 23, 1996) was an American biochemist. She was notable for discovery of carbamoyl phosphate, a chemical substance that is key to the biosynthesis of arginine and urea, and for the biosynthesis of pyrimidine nucleotides. Jones became the first woman to hold a chair at the University of North Carolina at Chapel Hill, and the first woman to become a department chair at the medical school. She was a member of the National Academy of Sciences. She was also president of the Association of Medical School Departments of Biochemistry, president of the American Society for Biochemistry and Molecular Biology, and president of the American Association of University Professors. The New York Times called her a "crucial researcher on DNA" and said that her studies laid the foundation for basic cancer research. She died of cancer on August 23, 1996. Early life Jones was born in La Grange Park, Illinois, on December 12, 1922. Her parents we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pyrimidine
Pyrimidine (; ) is an aromatic, heterocyclic, organic compound similar to pyridine (). One of the three diazines (six-membered heterocyclics with two nitrogen atoms in the ring), it has nitrogen atoms at positions 1 and 3 in the ring. The other diazines are pyrazine (nitrogen atoms at the 1 and 4 positions) and pyridazine (nitrogen atoms at the 1 and 2 positions). In nucleic acids, three types of nucleobases are pyrimidine derivatives: cytosine (C), thymine (T), and uracil (U). Occurrence and history The pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives, including the nucleotides cytosine, thymine and uracil, thiamine (vitamin B1) and alloxan. It is also found in many synthetic compounds such as barbiturates and the HIV drug, zidovudine. Although pyrimidine derivatives such as alloxan were known in the early 19th century, a laboratory synthesis of a pyrimidine was not carried out until 1879, when Grimaux reported the ...

Fritz Lipmann
Fritz Albert Lipmann (; June 12, 1899 – July 24, 1986) was a German-American biochemist and a co-discoverer in 1945 of coenzyme A. For this, together with other research on coenzyme A, he was awarded the Nobel Prize in Physiology or Medicine in 1953 (shared with Hans Adolf Krebs). Early life and education Lipmann was born in Königsberg, Germany, to a Jewish family. His parents were Gertrud (Lachmanski) and Leopold Lipmann, an attorney. Lipmann studied medicine at the University of Königsberg, Berlin, and Munich, graduating in Berlin in 1924. He returned to Königsberg to study chemistry under Professor Hans Meerwein. In 1926 he joined Otto Meyerhof at the Kaiser Wilhelm Institute for Biology, Dahlem, Berlin, for his doctoral thesis. After that he followed Meyerhof to Heidelberg to the Kaiser Wilhelm Institute for Medical Research. Career From 1939 on, Lipmann lived and worked in the United States.

Cathepsin C
Cathepsin C (CTSC) also known as dipeptidyl peptidase I (DPP-I) is a lysosomal exo-cysteine protease belonging to the peptidase C1 protein family, a subgroup of the cysteine cathepsins. In humans, it is encoded by the ''CTSC'' gene. Function Cathepsin C appears to be a central coordinator for activation of many serine proteases in immune/inflammatory cells. Cathepsin C catalyses excision of dipeptides from the N-terminus of protein and peptide substrates, except if (i) the amino group of the N-terminus is blocked, (ii) the site of cleavage is on either side of a proline residue, (iii) the N-terminal residue is lysine or arginine, or (iv) the structure of the peptide or protein prevents further digestion from the N-terminus. Structure The cDNAs encoding rat, human, murine, bovine, dog and two ''Schistosome'' cathepsin Cs have been cloned and sequenced and show that the enzyme is highly conserved. The human and rat cathepsin C cDNAs encode precursors (prepro-cathepsin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph S
Joseph is a common male given name, derived from the Hebrew Yosef (יוֹסֵף). "Joseph" is used, along with "Josef", mostly in English, French and partially German languages.

Androsterone
Androsterone, or 3α-hydroxy-5α-androstan-17-one, is an endogenous steroid hormone, neurosteroid, and putative pheromone. It is a weak androgen with a potency that is approximately 1/7 that of testosterone. Androsterone is a metabolite of testosterone and dihydrotestosterone (DHT). In addition, it can be converted back into DHT via 3α-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase, bypassing conventional intermediates such as androstanedione and testosterone, and as such, can be considered to be a metabolic intermediate in its own right. Androsterone is also known to be an inhibitory androstane neurosteroid, acting as a positive allosteric modulator of the GABAA receptor, and possesses anticonvulsant effects. The unnatural enantiomer of androsterone is more potent as a positive allosteric modulator of GABAA receptors and as an anticonvulsant than the natural form. Androsterone's 3β-isomer is epiandrosterone, and its 5β-epimer is etiocholanolone. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armour And Company
Armour & Company was an American company and was one of the five leading firms in the meat packing industry. It was founded in Chicago, in 1867, by the Armour brothers led by Philip Danforth Armour. By 1880, the company had become Chicago's most important business and had helped make Chicago and its Union Stock Yards the center of America's meatpacking industry. During the same period, its facility in Omaha, Nebraska, boomed, making the city's meatpacking industry the largest in the nation by 1959. In connection with its meatpacking operations, the company also ventured into pharmaceuticals (Armour Pharmaceuticals) and soap manufacturing, introducing Dial soap in 1948. Presently, the Armour food brands are split between Smithfield Foods (for refrigerated meat - "Armour Meats") and ConAgra Brands (for canned shelf-stable meat products - "Armour Star"). The Armour pharmaceutical brand is owned by Forest Laboratories. Dial soap is now owned by Henkel. History 1863–1970 Armo ...

Cancer Research
Cancer research is research into cancer to identify causes and develop strategies for prevention, diagnosis, treatment, and cure. Cancer research ranges from epidemiology, molecular bioscience to the performance of clinical trials to evaluate and compare applications of the various cancer treatments. These applications include surgery, radiation therapy, chemotherapy, hormone therapy, immunotherapy and combined treatment modalities such as chemo-radiotherapy. Starting in the mid-1990s, the emphasis in clinical cancer research shifted towards therapies derived from biotechnology research, such as cancer immunotherapy and gene therapy. Cancer research is done in academia, research institutes, and corporate environments, and is largely government funded. History Cancer research has been ongoing for centuries. Early research focused on the causes of cancer. Percivall Pott identified the first environmental trigger (chimney soot) for cancer in 1775 and cigarette smoking was identif ...
