Vladimir Vladimirovich Sakharov
Vladimir Vladimirovich Sakharov (28 February 1902 – 9 January 1969) was a Soviet cytogeneticist who studied mutagenesis by radiation with applications to agricultural and human genetics. He was a professor at the K. A. Timiriazev Agricultural Academy. Sakharov was born Simbirsk to agronomist Vladimir and teacher Maria Antonovna Ponyatovskaya, daughter of a Moscow physician. The family moved to Moscow in 1919 and Sakharov went to the Moscow State University in 1920 and graduated in 1926 after working at the Institute of Experimental Biology with a dissertation on “Novaya mutatsia u drozofily” (“New Mutation in Drosophila”) and “Razbor muzykalnykh genealogy” (“Analysis of Musical Genealogies”). He then taught at a Moscow school before joining the IEB in 1927 to research under Nikolai Koltsov. He then moved to work at the Moscow Pharmaceutical Institute and then directed the Institute of General Genetics. He became a professor at the K. A. Timiriazev Moscow Agricultur ...

Ulyanovsk
Ulyanovsk, known until 1924 as Simbirsk, is a city and the administrative center of Ulyanovsk Oblast, Russia, located on the Volga River east of Moscow. Population: The city, founded as Simbirsk (), was the birthplace of Vladimir Lenin (born Ulyanov), for whom it was renamed after his death in 1924; and of Alexander Kerensky, the leader of the Russian Provisional Government which Lenin overthrew during the October Revolution of 1917. It is also famous for its writers such as Ivan Goncharov, Nikolay Yazykov and Nikolay Karamzin, and for painters such as Arkady Plastov and Nikas Safronov. UNESCO has designated Ulyanovsk as a City of Literature since 2015. History Simbirsk was founded in 1648 by the boyar Bogdan Khitrovo. The fort of "Simbirsk" (alternatively "Sinbirsk") was strategically placed on a hill on the Western bank of the Volga River. The fort was meant to protect the eastern frontier of the Tsardom of Russia from the nomadic tribes and to establish a permanent royal ...

Nikolai Koltsov
Nikolai Konstantinovich Koltsov (russian: Николай Константинович Кольцов; July 14, 1872 – December 2, 1940) was a Russian biologist and a pioneer of modern genetics. Among his students were Nikolay Timofeeff-Ressovsky, Vladimir Pavlovich Efroimson, A.S. Serebrovsky, and Nikolay Dubinin. Along with his students, he demonstrated the fine structure of genes, and examined the structure of the cell and pioneered the idea of a cytoskeleton. His career was cut short in Stalinist Russia due to the entanglement of Marxist ideology and interpretations that genetics was a science that supported racism, fascism and eugenics. He died unexpectedly following government persecution and there are allegations that he was executed. Biography Koltsov was born in a well-to do family and graduated from Moscow University in 1894 and was a professor there (1895–1911). He established and directed the Institute of Experimental Biology in the middle of 1917, just before the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goitre
A goitre, or goiter, is a swelling in the neck resulting from an enlarged thyroid gland. A goitre can be associated with a thyroid that is not functioning properly. Worldwide, over 90% of goitre cases are caused by iodine deficiency. The term is from the Latin ''gutturia'', meaning throat. Most goitres are not cancerous (benign), though they may be potentially harmful. Signs and symptoms A goitre can present as a palpable or visible enlargement of the thyroid gland at the base of the neck. A goitre, if associated with hypothyroidism or hyperthyroidism, may be present with symptoms of the underlying disorder. For hyperthyroidism, the most common symptoms are associated with adrenergic stimulation: tachycardia (increased heart rate), palpitations, nervousness, tremor, increased blood pressure and heat intolerance. Clinical manifestations are often related to hypermetabolism, (increased metabolism), excessive thyroid hormone, an increase in oxygen consumption, metabolic changes in ...

Mutagenesis
Mutagenesis () is a process by which the genetic information of an organism is changed by the production of a mutation. It may occur spontaneously in nature, or as a result of exposure to mutagens. It can also be achieved experimentally using laboratory procedures. A mutagen is a mutation-causing agent, be it chemical or physical, which results in an increased rate of mutations in an organism's genetic code. In nature mutagenesis can lead to cancer and various heritable diseases, and it is also a driving force of evolution. Mutagenesis as a science was developed based on work done by Hermann Muller, Charlotte Auerbach and J. M. Robson in the first half of the 20th century. History DNA may be modified, either naturally or artificially, by a number of physical, chemical and biological agents, resulting in mutations. Hermann Muller found that "high temperatures" have the ability to mutate genes in the early 1920s, and in 1927, demonstrated a causal link to mutation upon experimen ...

Colchicine
Colchicine is a medication used to treat gout and Behçet's disease. In gout, it is less preferred to NSAIDs or steroids. Other uses for colchicine include the management of pericarditis and familial Mediterranean fever. Colchicine is taken by mouth. Colchicine has a narrow therapeutic index, so overdosing is a significant risk. Common side effects of colchicine include gastrointestinal upset, particularly at high doses. Severe side effects may include low blood cells and rhabdomyolysis, and the medication can be deadly in overdose. Whether colchicine is safe for use during pregnancy is unclear, but its use during breastfeeding appears to be safe. Colchicine works by decreasing inflammation via multiple mechanisms. Colchicine, in the form of the autumn crocus (''Colchicum autumnale''), has been used as early as 1500 BC to treat joint swelling. It was approved for medical use in the United States in 1961. It is available as a generic medication. In 2020, it was the 241st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Geneticists
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk (Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government that ...
