Szybalski's Rule
Szybalski's rule says that lower-protein particles like viruses contain more purines than pyrimidine in their nucleic acid sequence. This is to prevent double-stranded RNA formation of one or two separate RNA strand that have complementary regions. The formation of a double-stranded RNA is not efficient for viruses as it may delay or stop RNA replication or protein formation. The rule is named for Wacław Szybalski Wacław Szybalski (9 September 1921 – 16 December 2020) was a Polish-American professor of oncology at the McArdle Laboratory for Cancer Research, University of Wisconsin–Madison Medical School.

Typhus
Typhus, also known as typhus fever, is a group of infectious diseases that include epidemic typhus, scrub typhus, and murine typhus. Common symptoms include fever, headache, and a rash. Typically these begin one to two weeks after exposure. The diseases are caused by specific types of bacterial infection. Epidemic typhus is due to '' Rickettsia prowazekii'' spread by body lice, scrub typhus is due to ''Orientia tsutsugamushi'' spread by chiggers, and murine typhus is due to '' Rickettsia typhi'' spread by fleas. Vaccines have been developed, but none are commercially available. Prevention is achieved by reducing exposure to the organisms that spread the disease. Treatment is with the antibiotic doxycycline. Epidemic typhus generally occurs in outbreaks when poor sanitary conditions and crowding are present. While once common, it is now rare. Scrub typhus occurs in Southeast Asia, Japan, and northern Australia. Murine typhus occurs in tropical and subtropical areas ...

Rudolf Weigl
Rudolf Stefan Jan Weigl (2 September 1883 – 11 August 1957) was a Polish biologist, physician and inventor, known for creating the first effective vaccine against epidemic typhus. He was nominated for the Nobel Prize in Medicine each year between 1930 and 1934, and from 1936 to 1939. Weigl worked during the Holocaust to save the lives of countless Jews by developing the vaccine for typhus and providing shelter to protect those suffering under the Nazi Germans in occupied Poland. For his contributions, he was named a Righteous Among the Nations in 2003. Life Weigl was born in Prerau, then part of the Austro-Hungarian Empire, to Austrian parents. When he was a child, his father died in a bicycle accident. His mother, Elisabeth Kroesel, married a Polish secondary-school teacher, Józef Trojnar. Weigl was raised in Jasło, Poland.

Feeder Of Lice
A louse-feeder was a job in interwar and Nazi-occupied Poland, at the '' Lviv Institute for Study of Typhus and Virology'' and the associated Institute in Kraków, Poland. Louse-feeders were human sources of blood for lice infected with typhus, which were then used to research possible vaccines against the disease. Research into a typhus vaccine was started in 1920 by parasitologist Rudolf Weigl. Weigl and his wife Zofia Weigl were some of the earliest lice feeders. During the Nazi occupation of the city, louse-feeding became the primary means of support and protection for many of the city's Polish intellectuals, including the mathematician Stefan Banach and the poet Zbigniew Herbert. While the profession carried a significant risk of infection, louse-feeders were given additional food rations, were protected from being shipped to slave labour camps and German concentration camps, and were permitted to move around the occupied city.

Operation Barbarossa
Operation Barbarossa (german: link=no, Unternehmen Barbarossa; ) was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. The operation, code-named after Frederick Barbarossa ("red beard"), a 12th-century Holy Roman emperor and German king, put into action Nazi Germany's ideological goal of conquering the western Soviet Union to repopulate it with Germans. The German aimed to use some of the conquered people as forced labour for the Axis war effort while acquiring the oil reserves of the Caucasus as well as the agricultural resources of various Soviet territories. Their ultimate goal was to create more (living space) for Germany, and the eventual extermination of the indigenous Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. In the two years leading up to the invasion, Nazi Germany and the Soviet Union signed political and economic pacts fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biotechnology
Biotechnology is the integration of natural sciences and engineering sciences in order to achieve the application of organisms, cells, parts thereof and molecular analogues for products and services. The term ''biotechnology'' was first used by Károly Ereky in 1919, meaning the production of products from raw materials with the aid of living organisms. Definition The concept of biotechnology encompasses a wide range of procedures for modifying living organisms according to human purposes, going back to domestication of animals, cultivation of the plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. The American Chemical Society defines biotechnology as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materia ...
