Mikhail Chumakov
Mikhail Petrovich Chumakov (russian: Михаи́л Петро́вич Чумако́в) (November 14, 1909 – June 11, 1993) was a Soviet microbiologist and virologist most famous for conducting pivotal large-scale clinical trials that led to licensing of the Oral Polio Vaccine (OPV) developed by Albert B. Sabin. Life and work Chumakov graduated in 1931 from Moscow State University Medical School that was later transformed into I.M. Sechenov Moscow Medical Academy. In 1937 Chumakov participated in a scientific expedition to Khabarovsk region of Soviet Far East that was led by Professor Lev A. Zilber. Together with his colleagues he discovered the etiology of a new transmissible neurological disease called tick-borne encephalitis (TBE) and isolated the virus that causes it. He was accidentally infected with the virus and developed encephalitis that led to a permanent loss of hearing and paralysis of the right arm. For this discovery he was awarded Stalin Prize of First Degree in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microbiology
Microbiology () is the scientific study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology. Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. Microbiologists traditionally relied on culture, staining, and microscopy. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means. Microbiologists often rely on molecular biology tools such as DNA sequence based identification, for example the 16S rRNA gene sequence used for bacteria identification. Viruses have been variably classified as organisms, as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctors' Plot
The "Doctors' plot" affair, group=rus was an alleged conspiracy of prominent Soviet medical specialists to murder leading government and party officials. It was also known as the case of saboteur doctors or killer doctors. In 1951–1953, a group of predominantly Jewish doctors from Moscow were accused of a conspiracy to assassinate Soviet leaders. This was later accompanied by publications of antisemitic character in the media, which talked about the threats of Zionism and condemned people with Jewish surnames. Following this, many doctors, both Jews and non-Jews, were dismissed from their jobs, arrested, and tortured to produce admissions. A few weeks after the death of Stalin in 1953, the new Soviet leadership said there was a lack of evidence regarding the Doctors' plot and the case was dropped. Soon after, it was declared that the case had been a fabrication. Beginnings A number of theories attempt to explain the origins of the Doctors' plot case. Historians typically re ...

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 ...
