A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. Other common names include repetitive stress disorders, cumulative trauma disorders (CTDs), and overuse syndrome.
Escherichia coli, also known as E. coli, is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms (endotherms). Most E. coli strains are harmless, but some serotypes (EPEC, ETEC etc.) can cause serious food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls. The harmless strains are part of the normal microbiota of the gut, and can benefit their hosts by producing vitamin K2, (which helps blood to clot) and preventing colonisation of the intestine with pathogenic bacteria, having a symbiotic relationship. E. coli is expelled into the environment within fecal matter. The bacterium grows massively in fresh fecal matter under aerobic conditions for 3 days, but its numbers decline slowly afterwards.
Vibrio cholerae is a Gram-negative, comma-shaped bacterium. The bacterium's natural habitat is brackish or saltwater where they attach themselves easily to the chitin-containing shells of crabs, shrimps, and other shellfish. Some strains of V. cholerae cause the disease cholera, which can be derived from the consumption of undercooked or raw marine life species. V. cholerae is a facultative anaerobe and has a flagellum at one cell pole as well as pili. V. cholerae can undergo respiratory and fermentative metabolism. When ingested, V. cholerae can cause diarrhea and vomiting in a host within several hours to 2–3 days of ingestion. V. cholerae was first isolated as the cause of cholera in 1854 by Italian anatomist Filippo Pacini and by the Catalan Joaquim Balcells i Pascual in the same year, but their discovery was not widely known until Robert Koch, working independently 30 years later, publicized the knowledge and the means of fighting the disease.
The cantaloupe, rockmelon, sweet melon, or spanspek is a melon that is a variety of the muskmelon species from the family Cucurbitaceae.
Staphylococcus aureus is a Gram-positive, round-shaped bacterium that is a member of the Firmicutes, and it is a usual member of the microbiota of the body, frequently found in the upper respiratory tract and on the skin. It is often positive for catalase and nitrate reduction and is a facultative anaerobe that can grow without the need for oxygen. Although S. aureus usually acts as a commensal of the human microbiota it can also become an opportunistic pathogen, being a common cause of skin infections including abscesses, respiratory infections such as sinusitis, and food poisoning. Pathogenic strains often promote infections by producing virulence factors such as potent protein toxins, and the expression of a cell-surface protein that binds and inactivates antibodies. The emergence of antibiotic-resistant strains of S. aureus such as methicillin-resistant S. aureus (MRSA) is a worldwide problem in clinical medicine. Despite much research and development, no vaccine for S. aureus has been approved.
In organic chemistry, the cycloalkanes are the monocyclic saturated hydrocarbons. In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring, and all of the carbon-carbon bonds are single. Cycloalkanes are named analogously to their normal alkane counterparts of the same carbon count: cyclopropane, cyclobutane, cyclopentane, cyclohexane, etc. The larger cycloalkanes, with more than 20 carbon atoms are typically called cycloparaffins.
Injury, also known as physical trauma, is damage to the body caused by external force. This may be caused by accidents, falls, hits, weapons, and other causes. Major trauma is injury that has the potential to cause prolonged disability or death. In 2013, 4.8 million people world-wide died from injuries, up from 4.3 million in 1990. More than 30% of these deaths were transport-related injuries. In 2013, 367,000 children under the age of five died from injuries, down from 766,000 in 1990. Injuries are the cause of 9% of all deaths, and are the sixth-leading cause of death in the world.
Haemophilus influenzae is a Gram-negative, coccobacillary, facultatively anaerobic capnophilic pathogenic bacterium of the family Pasteurellaceae. H. influenzae was first described in 1892 by Richard Pfeiffer during an influenza pandemic.
The Thermoactinomycetaceae are a family of Gram-positive endospore-forming bacteria.
A march, as a musical genre, is a piece of music with a strong regular rhythm which in origin was expressly written for marching to and most frequently performed by a military band. In mood, marches range from the moving death march in Wagner's Götterdämmerung to the brisk military marches of John Philip Sousa and the martial hymns of the late 19th century. Examples of the varied use of the march can be found in Beethoven's Eroica Symphony, in the Marches Militaires of Franz Schubert, in the Marche funèbre in Chopin's Sonata in B flat minor, the "Jäger March" in the Op. 91a by Jean Sibelius, and in the Dead March in Handel's Saul.
Cannabis strains are either pure or hybrid varieties of the plant genus Cannabis, which encompasses the species C. sativa, C. indica, and C. ruderalis.
Visa requirements for British citizens are administrative entry restrictions by the authorities of other states placed on citizens of the United Kingdom. As of 13 October 2020, British citizens had visa-free or visa on arrival access to 185 countries and territories, ranking their passport 7th in terms of travel freedom according to the Henley Passport Index. Additionally, the World Tourism Organisation also published a report on 15 January 2016 ranking the passport 1st in the world in terms of travel freedom, with the mobility index of 160.
Escherichia coli O104:H4 is an enteroaggregative Escherichia coli strain of the bacterium Escherichia coli, and the cause of the 2011 Escherichia coli O104:H4 outbreak. The "O" in the serological classification identifies the cell wall lipopolysaccharide antigen, and the "H" identifies the flagella antigen.
BacDive is a bacterial metadatabase that provides strain-linked information about bacterial and archaeal biodiversity.
Seinonella is a Gram-positive and aerobic bacterial genus from the family of Thermoactinomycetaceae. Up to now there is only one species of this genus known.
The 2017–2018 South African listeriosis outbreak was a widespread outbreak of Listeria monocytogenes food poisoning that resulted from contaminated processed meats produced by Enterprise Foods, a subsidiary of Tiger Brands, in Polokwane. There were 1,060 confirmed cases of listeriosis during the outbreak, and about 216 deaths. It is the world's worst ever listeriosis outbreak.
Samuel "Sammy" Strain Jr. is an American R&B vocalist, known for his time as a member of Little Anthony and the Imperials and The O'Jays (1975-1992).
Lineage B.1.1.7, also known as 20I/501Y.V1, Variant of Concern 202012/01 (VOC-202012/01) or commonly as the UK variant or British variant, is a variant of SARS-CoV-2, the virus that causes COVID-19. One of several variants believed to be of particular importance, it is estimated to be 40%–80% more transmissible than wild-type SARS-CoV-2 and was detected in November 2020 from a sample taken in September, during the COVID-19 pandemic in the United Kingdom; it began to spread quickly by mid-December, and is correlated with a significant increase in SARS-CoV-2 infections in the country. This increase is thought to be at least partly because of one or more mutations in the virus's spike protein. The variant is also notable for having more mutations than normally seen.
The 501Y.V2 variant, also known as 20H/501Y.V2, B.1.351 lineage and South African COVID-19 variant, is a variant of SARS-CoV-2, the virus that causes COVID-19. One of several SARS-CoV-2 variants believed to be of particular importance, it was first detected in the Nelson Mandela Bay metropolitan area of the Eastern Cape province of South Africa and reported by the country's health department on 18 December 2020.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), has many variants; some are or have been believed to be of particular importance. This article discusses such notable variants of SARS-CoV-2, and also discusses notable mutations found in some, or all, of these variants.
