Tamara Iosifovna Balezina
Tamara Iosifovna Balezina (28 April 1913 – 11 August 2010) was a Soviet Union-Russian microbiologist and biologist who played a key role in the discovery and production of penicillin in the Soviet Union. Early life and education Balezina attended a seven-year medical program and started in 1929 at the Stalin Medical Institute, but she moved to the Kuibyshev Medical Institute after two years in 1931. She graduated with honors from the sanitary and hygienic faculty of the Kuibyshev Medical Institute in 1935. She began postgraduate studies in microbiology in 1936, and transferred to the graduate school of V.I.E.M. ( Institute of Experimental Medicine) in Moscow to follow her husband. On 7 June 1944, she defended her Ph.D. thesis on "Derivation, research and clinical applications of penicillin". Career In 1942 she was tasked with organizing a laboratory to conduct research on penicillin in 1942 and she was the one responsible for the hands-on work while Zinaida Yermolyeva or ...

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 they have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Institute Of Experimental Medicine
The Institute of Experimental Education in St Petersburg is one of the oldest scientific establishments in Russia. It was founded by Alexander of Oldenburg in 1888 along the lines of Louis Pasteur's Pasteur Institute. It was here that Pavlov did much of his groundbreaking physiological research. The portal of the library is decorated with tiles created by Peter Vaulin between 1911 and 1913. Departments The institute was divided into eight departments: * Chemistry headed by M.V.Nentsky * Epizootiology headed by K.Ya.Gelman * General Bacteriology headed by Sergei Winogradsky Sergei Nikolaievich Winogradsky (or Vinohradsky; published under the name of Sergius Winogradsky or M.

Moscow
Moscow ( , US chiefly ; rus, links=no, Москва, r=Moskva, p=mɐskˈva, a=Москва.ogg) is the capital and largest city of Russia. The city stands on the Moskva River in Central Russia, with a population estimated at 13.0 million residents within the city limits, over 17 million residents in the urban area, and over 21.5 million residents in the metropolitan area. The city covers an area of , while the urban area covers , and the metropolitan area covers over . Moscow is among the world's largest cities; being the most populous city entirely in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent. First documented in 1147, Moscow grew to become a prosperous and powerful city that served as the capital of the Grand Duchy that bears its name. When the Grand Duchy of Moscow evolved into the Tsardom of Russia, Moscow remained the political and economic center for most of the Tsardom's history. When th ...

Zinaida Yermolyeva
Zinaida Vissarionovna Yermolyeva (russian: Зинаида Виссарионовна Ермольева) ( – December 2, 1974) was a Soviet microbiologist of Don Cossack origin most notable for independently synthesizing penicillin for the Soviet military during World War II. She was a member of the USSR Academy of Medical Sciences at the time of her death. Career In 1921, Yermolyeva graduated from the medical faculty of Donskoy University. From 1925 on, she acted as the head of several microbiology and epidemiology institutes in Moscow. In 1925, Yermolyeva was appointed head of the Department of Microbial Biochemistry at the USSR Academy of Sciences. There, she began her research on bacteriophages and naturally-occurring antimicrobial agents—lysozyme in particular. During the Second World War, she and Tamara Balezina isolated a penicillin-producing strain of ''Penicillium crustosum''. It was first used in Soviet hospitals in 1943. In 1942, she published the results of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Fleming
Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin. His discovery in 1928 of what was later named benzylpenicillin (or penicillin G) from the mould ''Penicillium rubens'' is described as the "single greatest victory ever achieved over disease." For this discovery, he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain. He also discovered the enzyme lysozyme from his nasal discharge in 1922, and along with it a bacterium he named ''Micrococcus Lysodeikticus'', later renamed ''Micrococcus luteus''. Fleming was knighted for his scientific achievements in 1944. In 1999, he was named in ''Time'' magazine's list of the 100 Most Important People of the 20th century. In 2002, he was chosen in the BBC's television poll for determining the 100 Greatest Britons, and in 2009, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penicillium Crustosum
''Penicillium crustosum'' is a blue-green or blue-grey mold that can cause food spoilage, particularly of protein-rich foods such as meats and cheeses. It is identified by its complex biseriate conidiophores on which phialides produce asexual spores. It can grow at fairly low temperatures (it is a psychrophile), and in low water activity environments. ''Penicillium crustosum'' produces mycotoxins, most notoriously the neurotoxic penitrems, including the best known penitrem toxin, penitrem A, and including penitrems A through G. Penitrem G has been shown to have insecticidal activity. In addition, ''P. crustosum'' can produce thomitrems A and E, and roquefortine C. Consumption of foods spoiled by this mold can cause transient neurological symptoms such as tremors. In dogs, symptoms can include vomiting, convulsion, tremors, ataxia, and tachycardia Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. In general, a resting heart rate ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interferon
Interferons (IFNs, ) are a group of signaling proteins made and released by host cells in response to the presence of several viruses. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses. IFNs belong to the large class of proteins known as cytokines, molecules used for communication between cells to trigger the protective defenses of the immune system that help eradicate pathogens. Interferons are named for their ability to "interfere" with viral replication by protecting cells from virus infections. However, virus-encoded genetic elements have the ability to antagonize the IFN response contributing to viral pathogenesis and viral diseases. IFNs also have various other functions: they activate immune cells, such as natural killer cells and macrophages, and they increase host defenses by up-regulating antigen presentation by virtue of increasing the expression of major histocompatibility complex (M ...

Women Microbiologists
A woman is an adult female human. Prior to adulthood, a female human is referred to as a girl (a female child or adolescent). The plural ''women'' is sometimes used in certain phrases such as "women's rights" to denote female humans regardless of age. Typically, women inherit a pair of X chromosomes, one from each parent, and are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, SRY-gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. A fully developed woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. Women have significantly less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Througho ...
