Edgar Allen
Edgar Allen (May 2, 1892 – February 3, 1943) was an American anatomist and physiologist. He is known for the discovery of estrogen and his role in creating the field of endocrinology. Born on Cañon (Canyon) City, Colorado, Allen was educated at Brown University. After serving in World War I he took a position at Washington University in St. Louis until, in 1923, he was appointed to the chair of anatomy at the University of Missouri in Columbia, Missouri. Ten years later he was appointed to the chair at Yale University. At Missouri, he began his studies of sex hormones. While it was commonly believed at the time that the female reproductive cycle was controlled by substance in the '' corpus luteum'', Allen sought the answer in the follicles surrounding the ovum, leading to his discovery of estrogen, though it was identified six years later by Adolf Butenandt in 1929. Allen died of a heart attack in 1943 while on duty with the United States Coast Guard. References Fur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown University Alumni
Brown is a color. It can be considered a composite color, but it is mainly a darker shade of orange. In the CMYK color model used in printing or painting, brown is usually made by combining the colors orange and black. In the RGB color model used to project colors onto television screens and computer monitors, brown combines red and green. The color brown is seen widely in nature, wood, soil, human hair color, eye color and skin pigmentation. Brown is the color of dark wood or rich soil. According to public opinion surveys in Europe and the United States, brown is the least favorite color of the public; it is often associated with plainness, the rustic, feces, and poverty. More positive associations include baking, warmth, wildlife, and the autumn. Etymology The term is from Old English , in origin for any dusky or dark shade of color. The first recorded use of ''brown'' as a color name in English was in 1000. The Common Germanic adjectives ''*brûnoz and *brûnâ'' mean ...

American National Biography
The ''American National Biography'' (ANB) is a 24-volume biographical encyclopedia set that contains about 17,400 entries and 20 million words, first published in 1999 by Oxford University Press under the auspices of the American Council of Learned Societies. Background A 400-entry supplement appeared in 2002. Additional funding came from the Rockefeller Foundation, the Andrew W. Mellon Foundation and the National Endowment for the Humanities. The ''ANB'' bills itself as the successor of the ''Dictionary of American Biography'', which was first published between 1926 and 1937. It is not, however, a strict superset of this older publication; the selection of topics was made anew. It is commonly available in the reference sections of United States libraries, and is available online by subscription (see external links). Awards and reception In 1999, the American Library Association awarded the ''American National Biography'' its Dartmouth Medal as a reference work of outsta ...

Science (journal)
''Science'', also widely referred to as ''Science Magazine'', is the peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS) and one of the world's top academic journals. It was first published in 1880, is currently circulated weekly and has a subscriber base of around 130,000.

Adolf Butenandt
Adolf Friedrich Johann Butenandt (; 24 March 1903 – 18 January 1995) was a German biochemist. He was awarded the Nobel Prize in Chemistry in 1939 for his "work on sex hormones." He initially rejected the award in accordance with government policy, but accepted it in 1949 after World War II. He was President of the Max Planck Society from 1960 to 1972. He was also the first, in 1959, to discover the structure of the sex pheromone of silkworms which he named as bombykol. Biography Born in Lehe, near Bremerhaven, he started his studies at the University of Marburg. For his PhD he joined the working group of the Nobel laureate Adolf Windaus at the University of Göttingen and he finished his studies with a PhD in chemistry in 1927. His doctoral research was on the chemistry of the insecticidal toxin found in the roots of '' Derris elliptica'' which he isolated and characterized. After his Habilitation he became lecturer in Göttingen 1931. He became a professor ordinarius at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovum
The egg cell, or ovum (plural ova), is the female reproductive cell, or gamete, in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non- motile). If the male gamete ( sperm) is capable of movement, the type of sexual reproduction is also classified as oogamous. A nonmotile female gamete formed in the oogonium of some algae, fungi, oomycetes, or bryophytes is an oosphere. When fertilized the oosphere becomes the oospore. When egg and sperm fuse during fertilisation, a diploid cell (the zygote) is formed, which rapidly grows into a new organism. History While the non-mammalian animal egg was obvious, the doctrine ''ex ovo omne vivum'' ("every living nimal comes froman egg"), associated with William Harvey (1578–1657), was a rejection of spontaneous generation and preformationism as well as a bold assumption that mammals also reprodu ...

Corpus Luteum
The corpus luteum (Latin for "yellow body"; plural corpora lutea) is a temporary endocrine structure in female ovaries involved in the production of relatively high levels of progesterone, and moderate levels of estradiol, and inhibin A. It is the remains of the ovarian follicle that has released a mature ovum during a previous ovulation. The corpus luteum is colored as a result of concentrating carotenoids (including lutein) from the diet and secretes a moderate amount of estrogen that inhibits further release of gonadotropin-releasing hormone (GnRH) and thus secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). A new corpus luteum develops with each menstrual cycle. Development and structure The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle or oestrous cycle, following the release of a secondary oocyte from the follicle during ovulation. The follicle first forms a corpus hemorrhagicum before it bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
