London Underground Mosquito
The London Underground mosquito is a form of mosquito in the genus ''Culex''. It is found in the London Underground railway system as its name suggests, but has a worldwide distribution and long predates the existence of the London Underground. It was first described as a distinct species from Egyptian specimens by the biologist Peter Forsskål (1732–1763). He named this mosquito ''Culex molestus'' due to its voracious biting, but later biologists renamed it ''Culex pipiens'' f. ''molestus'' because there were no morphological differences between it and ''Culex pipiens''. Notably, this mosquito assaulted Londoners sleeping in the Underground during the Blitz, although similar populations were long known. A study from 2004 analyzing DNA microsatellites suggested that ''Culex molestus'' is likely a distinct species from ''Culex pipiens''. However, a more recent paper from 2012 argues that it is more accurately "a physiological and ecological variant of ''Cx. pipiens''" and ...

Form (zoology)
In zoology, the word "form" or ''forma'' (literally Latin for form) is a strictly informal term that is sometimes used to describe organisms. Under the ''International Code of Zoological Nomenclature'' the term has no standing (it is not accepted). In other words, although form names are Latin, and are sometimes wrongly appended to a binomial name, in a zoological context, forms have no taxonomic significance at all. Usage of the term Some zoologists use the word "form" or "forma" to describe variation in animals, especially insects, as part of a series of terms and abbreviations that are appended to the binomen or trinomen. Many 'typical specimens' may be described, but none should be considered absolute, unconditional or categorical. Forms have no official status, though they are sometimes useful in describing altitudinal or geographical clines. As opposed to morphs (see below), a subpopulation usually consists of a single form only at any given point of time. ''forma geographi ...

Egypt
Egypt ( ar, مصر , ), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia via a land bridge formed by the Sinai Peninsula. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world. Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science (journal)

Microsatellite (genetics)
A microsatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from one to six or more base pairs) are repeated, typically 5–50 times. Microsatellites occur at thousands of locations within an organism's genome. They have a higher mutation rate than other areas of DNA leading to high genetic diversity. Microsatellites are often referred to as short tandem repeats (STRs) by forensic geneticists and in genetic genealogy, or as simple sequence repeats (SSRs) by plant geneticists. Microsatellites and their longer cousins, the minisatellites, together are classified as VNTR (variable number of tandem repeats) DNA. The name "satellite" DNA refers to the early observation that centrifugation of genomic DNA in a test tube separates a prominent layer of bulk DNA from accompanying "satellite" layers of repetitive DNA. They are widely used for DNA profiling in cancer diagnosis, in kinship analysis (especially paternity testing) and in forensic identifica ...

MtDNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from t ...

Journal Of Parasitology
The ''Journal of Parasitology'' is a peer-reviewed medical journal covering research on parasites published bimonthly by Allen Press on behalf of the American Society of Parasitologists. Content includes research articles, brief research notes, announcements of the society, and book reviews. It was founded and edited by Henry Baldwin Ward in 1914. History In 1911, Charles C. Stiles and Brayton H. Ransom at the Bureau of Animal Industry in Washington, D.C., promulgated the need for parasitology journal in America. They asked Henry Baldwin Ward, at the time professor of zoology at the University of Illinois, to initiate the production. The name of the journal was proposed as ''The American Journal of Parasitology'', which George H. Simmons, secretary and editor for the ''Journal of the American Medical Association'' changed as the ''Journal of Parasitology'' as he felt that it would have more international recognition. Ward, as the owner and managing editor, released the first issu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithuanian Academy Of Sciences
The Lithuanian Academy of Sciences or LMA ( lt, Lietuvos mokslų akademija) is a state-funded independent organization in Lithuania dedicated for science and research. Its mission is to mobilize prominent scientists and initiate activities that would strengthen the welfare of Lithuania and contribute to the scientific, social, cultural and economic development of the country. History The idea of establishing the Lithuanian Academy of Sciences was proposed in 1773 by Marcin Odlanicki Poczobutt, Martynas Počobutas and other members of Vilnius University in the Grand Duchy of Lithuania, but it was not implemented due to wars and conflicts in the region. The idea of an independent institution for science and research was revived during the Lithuanian National Revival with the main proponents of it being the members of the Lithuanian Scientific Society, including Jonas Basanavičius and Jonas Šliūpas. However, the implementation began only in 1939, initially with the establishmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitemia
Parasitemia is the quantitative content of parasites in the blood. It is used as a measurement of parasite load in the organism and an indication of the degree of an active parasitic infection. Systematic measurement of parasitemia is important in many phases of the assessment of disease, such as in diagnosis and in the follow-up of therapy, particularly in the chronic phase, when cure depends on ascertaining a parasitemia of zero. The methods to be used for quantifying parasitemia depends on the parasitic species and its life cycle. For instance, in malaria, the number of blood-stage parasites can be counted using an optical microscope, on a special thick film (for low parasitemias) or thin film blood smear (for high parasitemias). The use of molecular biology Molecular biology is the branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions.
