Coronavirus Infections
Coronavirus diseases are caused by viruses in the coronavirus subfamily, a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, the group of viruses cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS and COVID-19. As of 2021, 45 species are registered as coronaviruses, whilst 11 diseases have been identified, as listed below. Coronaviruses are known for their shape resembling a stellar corona, such as that of the Sun visible during a total solar eclipse; '' corona'' is derived from the Latin word , meaning ' garland, wreath, crown'. It was coined by Tony Waterson (professor of virology at St Thomas' Hospital St Thomas' Hospital is a large NHS teaching hospital in Central London, England.

Middle East Respiratory Syndrome
Middle East respiratory syndrome (MERS) is a viral respiratory infection caused by ''Middle East respiratory syndrome–related coronavirus'' (MERS-CoV). Symptoms may range from none, to mild, to severe. Typical symptoms include fever, cough, diarrhea, and shortness of breath. The disease is typically more severe in those with other health problems. The first case was identified in June 2012 by Egyptian physician Ali Mohamed Zaki at the Dr. Soliman Fakeeh Hospital in Jeddah, Saudi Arabia, and most cases have occurred in the Arabian Peninsula. Over 2,500 cases have been reported as of January 2021, including 45 cases in the year 2020. About 35% of those who are diagnosed with the disease die from it. Larger outbreaks have occurred in South Korea in 2015 and in Saudi Arabia in 2018. MERS-CoV is a coronavirus believed to be originally from bats. However, humans are typically infected from camels, either during direct contact or indirectly. Spread between humans typically r ...

Stellar Corona
A corona ( coronas or coronae) is the outermost layer of a star's atmosphere. It consists of plasma. The Sun's corona lies above the chromosphere and extends millions of kilometres into outer space. It is most easily seen during a total solar eclipse, but it is also observable with a coronagraph. Spectroscopic measurements indicate strong ionization in the corona and a plasma temperature in excess of , much hotter than the surface of the Sun, known as the photosphere. The word ''corona'' is , in turn derived . History In 1724, French-Italian astronomer Giacomo F. Maraldi recognized that the aura visible during a solar eclipse belongs to the Sun, not to the Moon. In 1809, Spanish astronomer José Joaquín de Ferrer coined the term 'corona'. Based in his own observations of the 1806 solar eclipse at Kinderhook (New York), de Ferrer also proposed that the corona was part of the Sun and not of the Moon. English astronomer Norman Lockyer identified the first element unknown o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Tyrrell (physician)
David Arthur John Tyrrell (19 June 1925 – 2 May 2005) was a British virologist who was the director of the Common Cold Unit, which investigated viruses that caused common colds. He discovered the first human coronavirus (designated B814) in 1965. With June Almeida he made the first comparative study of human and chicken coronaviruses in 1967, and invented the name coronavirus in 1968. Biography Tyrrell was born on 19 June 1925 to Sidney Tyrrell and Agnes Kate Blewett. He had a younger brother Andrew. He attended elementary schools at Ashford, Middlesex. His family moved to Sheffield in 1940, where he completed secondary education at King Edward VII School. While studying medicine at the University of Sheffield he suffered from a detached retina, which meant he was exempted from military conscription, and had a lifelong preference for monocular microscopes. He graduated in 1948 and earned membership of the Royal College of Physicians in 1949. During those years he worked as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
June Almeida
June Dalziel Almeida (5 October 1930 – 1 December 2007) was a Scottish virologist, a pioneer in virus imaging, identification, and diagnosis. Her skills in electron microscopy earned her an international reputation. In 1964, Almeida was recruited by St Thomas's Hospital Medical School in London. By 1967, she had earned her Doctor of Science (Sc.D.) on the basis of her research and the resulting publications, while working in Canada, at Toronto's Ontario Cancer Institute and then in London at St Thomas's. she then continued her research at the Royal Postgraduate Medical School (RPGMS), which later became part of the Imperial College School of Medicine. Almeida succeeded in identifying viruses that were previously unknown, including—in 1966—a group of viruses that was later named coronavirus, due to their crown-like appearance. Her immune electron microscopy (IEM) innovations and insights contributed to research related to the diagnosis of hepatitis B, HIV, and rubel ...

Virology
Virology is the Scientific method, scientific study of biological viruses. It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host (biology), host cell (biology), cells for reproduction, their interaction with host organism physiology and immunity, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy. The identification of the causative agent of tobacco mosaic disease (TMV) as a novel pathogen by Martinus Beijerinck (1898) is now acknowledged as being the history of virology, official beginning of the field of virology as a discipline distinct from bacteriology. He realized the source was neither a bacterial nor a fungal infection, but something completely different. Beijerinck used the word "virus" to describe the mysterious agent in his 'contagium vivum fluidum' ('contagious living fluid'). Rosalind Franklin proposed the f ...

Dictionary
A dictionary is a listing of lexemes from the lexicon of one or more specific languages, often arranged alphabetically (or by radical and stroke for ideographic languages), which may include information on definitions, usage, etymologies, pronunciations, translation, etc.Webster's New World College Dictionary, Fourth Edition, 2002 It is a lexicographical reference that shows inter-relationships among the data. A broad distinction is made between general and specialized dictionaries. Specialized dictionaries include words in specialist fields, rather than a complete range of words in the language. Lexical items that describe concepts in specific fields are usually called terms instead of words, although there is no consensus whether lexicology and terminology are two different fields of study. In theory, general dictionaries are supposed to be semasiological, mapping word to definition, while specialized dictionaries are supposed to be onomasiological, first identifying ...

Crown
A crown is a traditional form of head adornment, or hat, worn by monarchs as a symbol of their power and dignity. A crown is often, by extension, a symbol of the monarch's government or items endorsed by it. The word itself is used, particularly in Commonwealth countries, as an abstract name for the monarchy itself, as distinct from the individual who inhabits it (that is, ''The Crown''). A specific type of crown (or coronet for lower ranks of peerage) is employed in heraldry under strict rules. Indeed, some monarchies never had a physical crown, just a heraldic representation, as in the constitutional kingdom of Belgium, where no coronation ever took place; the royal installation is done by a solemn oath in parliament, wearing a military uniform: the King is not acknowledged as by divine right, but assumes the only hereditary public office in the service of the law; so he in turn will swear in all members of "his" federal government''.
