Rebeca Gerschman
Rebeca Gerschman (June 19, 1903 – April 4, 1986) was an Argentinian biologist and physiologist who received a Ph.D. in Biochemistry and Pharmacy from the University of Buenos Aires. Known for her advances in the field of biochemistry, she was the first scientist to propose—in 1954—that free radicals contributed to oxygen toxicity and cell aging and death.Barassi, L. M.

Bernardo Houssay
Bernardo Alberto Houssay (April 10, 1887 – September 21, 1971) was an Argentine physiologist. Houssay was a co-recipient of the 1947 Nobel Prize for Physiology or Medicine for discovering the role played by pituitary hormones in regulating the amount of glucose in animals, sharing the prize with Carl Ferdinand Cori and Gerty Cori. He is the first Argentine Nobel laureate in the sciences. Biography Early life Bernardo Alberto Houssay was born April 10, 1887, in Buenos Aires. His parents Albert and Clara Houssay were immigrants from France. A precocious youngster, he was admitted to the Pharmacy School at the University of Buenos Aires at 14 years of age and subsequently to the Faculty of Medicine of the same university at 17 years old and was there from 1904 to 1910. While a third-year medical student, Houssay took up a post as a research and teaching assistant in the Chair of Physiology. Career After graduating, he quickly developed and presented his M.D. thesis on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Argentine Jews
The history of the Jews in Argentina goes back to the early sixteenth century, following the Jewish expulsion from Spain. Sephardi Jews fleeing persecution immigrated with explorers and colonists to settle in what is now Argentina, in spite of being forbidden from travelling to the American colonies. In addition, many of the Portuguese traders in the Viceroyalty of the Río de la Plata were Jewish. An organized Jewish community, however, did not develop until after Argentina gained independence from Spain in 1816. By mid-century, Jews from France and other parts of Western Europe, fleeing the social and economic disruptions of revolutions, began to settle in Argentina. Reflecting the composition of the later immigration waves, the current Jewish population is 80% Ashkenazi; while Sephardi and Mizrahi are a minority. Argentina has the largest Jewish population of any country in Latin America, although numerous Jews left during the 1970s and 1980s to escape the repression of th ...

Superoxide Dismutase
Superoxide dismutase (SOD, ) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide () radical into ordinary molecular oxygen (O2) and hydrogen peroxide (). Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. Hydrogen peroxide is also damaging and is degraded by other enzymes such as catalase. Thus, SOD is an important antioxidant defense in nearly all living cells exposed to oxygen. One exception is ''Lactobacillus plantarum'' and related lactobacilli, which use a different mechanism to prevent damage from reactive . Chemical reaction SODs catalyze the disproportionation of superoxide: : 2 HO2 → O2 + H2O2 In this way, is converted into two less damaging species. The pathway by which SOD-catalyzed dismutation of superoxide may be written, for Cu,Zn SOD, with the following reactions: * Cu2+-SOD + → Cu+-SOD + O2 (reduction of copper; oxidation of superoxide) * Cu+-S ...

Irwin Fridovich
Irwin Fridovich (August 2, 1929 – November 2, 2019) was an American biochemist who, together with his graduate student Joe M. McCord, discovered the enzymatic activity of copper-zinc superoxide dismutase (SOD),—to protect organisms from the toxic effects of superoxide free radicals formed as a byproduct of normal oxygen metabolism. Subsequently, Fridovich's research group also discovered the manganese-containing and the iron-containing SODs from ''Escherichia coli'' and the mitochondrial MnSOD ( SOD2), now known to be an essential protein in mammals. He spent the rest of his career studying the biochemical mechanisms of SOD and of biological superoxide toxicity, using bacteria as model systems. Fridovich was also Professor Emeritus of Biochemistry at Duke University. Academic career From 1951 to 1952, Fridovich served as a medical research associate at Cornell Medical College. He held junior teaching positions in biochemistry at Duke University 1956 to 1961 and was a v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nobel Prize In Physiology Or Medicine
The Nobel Prize in Physiology or Medicine is awarded yearly by the Nobel Assembly at the Karolinska Institute for outstanding discoveries in physiology or medicine. The Nobel Prize is not a single prize, but five separate prizes that, according to Alfred Nobel's 1895 will, are awarded "to those who, during the preceding year, have conferred the greatest benefit to humankind". Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace. The Nobel Prize is presented annually on the anniversary of Alfred Nobel's death, 10 December. As of 2022, 114 Nobel Prizes in Physiology or Medicine have been awarded to 226 laureates, 214 men and 12 women. The first one was awarded in 1901 to the German physiologist, Emil von Behring, for his work on serum therapy and the development of a vaccine against diphtheria. The first woman to receive the Nobel Prize in Physiology or Medicine, Gerty Cori, received it in 1947 for her role in elucidati ...

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
