Conenose Bug
The members of the Triatominae , a subfamily of the Reduviidae, are also known as conenose bugs, kissing bugs (so-called from their habit of feeding from around the mouths of people), or vampire bugs. Other local names for them used in The Americas include ''barbeiros'', ''vinchucas'', ''pitos'', ''chipos'' and ''chinches''. Most of the 130 or more species of this subfamily feed on vertebrate blood; a very few species feed on invertebrates. They are mainly found and widespread in the Americas, with a few species present in Asia and Africa. These bugs usually share shelter with nesting vertebrates, from which they suck blood. In areas where Chagas disease occurs (from the southern United States to northern Argentina), all triatomine species are potential vectors of the Chagas disease parasite ''Trypanosoma cruzi'', but only those species that are well adapted to living with humans (such as ''Triatoma infestans'' and ''Rhodnius prolixus'') are considered important vectors.

René Jeannel
René Jeannel (23 March 1879 – 20 February 1965) was a French entomologist.Jean-Jacques Amigo, « Jeannel (René, Gabriel, Marie) », in Nouveau Dictionnaire de biographies roussillonnaises, vol. 3 Sciences de la Vie et de la Terre, Perpignan, Publications de l'olivier, 2017, 915 p. () He was director of the Muséum national d'histoire naturelle from 1945 to 1951. Jeannel's most important work was on the insect fauna of caves in the Pyrenees, France and in the Carpathians, Romania. He also worked in Africa. Jeannel specialised in Leiodidae (then Silphidae or Catopidae) but authored a large number of papers and works on other Coleoptera. He was a member of the Romanian Academy. As the son of a medical officer in the French military, Jeannel was expected to succeed his father. However, after developing an interest, during his studies in Toulouse, in cave exploration and especially cave fauna, he began considering a career in biological science instead. His interest was especially ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
São Francisco River
The São Francisco River (, ) is a large river in Brazil. With a length of , it is the longest river that runs entirely in Brazilian territory, and the fourth longest in South America and overall in Brazil (after the Amazon, the Paraná and the Madeira). It used to be known as the by the indigenous people before colonisation, and is today also known as . The São Francisco originates in the Canastra mountain range in the central-western part of the state of Minas Gerais. It runs generally north in the states of Minas Gerais and Bahia, behind the coastal range, draining an area of over , before turning east to form the border between Bahia on the right bank and the states of Pernambuco and Alagoas on the left one. After that, it forms the boundary between the states of Alagoas and Sergipe and washes into the Atlantic Ocean. In addition to the five states which the São Francisco directly traverses or borders, its drainage basin also includes tributaries from the state of Goià ...

Carlos Chagas
Carlos Justiniano Ribeiro Chagas, or Carlos Chagas (; July 9, 1879 – November 8, 1934), was a Brazilian sanitary physician, scientist, and bacteriologist who worked as a clinician and researcher. He discovered Chagas disease, also called ''American trypanosomiasis'', in 1909, while he was working at the Oswaldo Cruz Institute in Rio de Janeiro. Chagas's work holds a unique place in the history of medicine. Working in primitive conditions, Chagas described in detail a previously-unknown infectious disease, its pathogen, vector (Triatominae), host, clinical manifestations, and epidemiology. Chagas was also the first to discover and illustrate the parasitic fungal genus ''Pneumocystis'', which later became infamous for being linked to pneumocystis pneumonia in AIDS patients. Early life Chagas was the son of José Justiniano das Chagas, a coffee farmer from Minas Gerais, and Mariana Cândida Chagas, both of Portuguese descent. After his secondary studies at Itu, São Paulo and S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Darwin's Illness
For much of his adult life, Charles Darwin's health was repeatedly compromised by an uncommon combination of symptoms, leaving him severely debilitated for long periods of time. However, in some ways this may have helped his work, and Charles Darwin wrote "Even ill-health, though it has annihilated several years of my life, has saved me from the distractions of society and amusement." He consulted numerous doctors, but, with the medical science of the time, the cause remained undiagnosed. He tried all available treatments, but, at best, they had only temporary success. More recently, there has been much speculation as to the nature of his illness. Development of illness and symptoms As a medical student at the University of Edinburgh, Darwin found that he was too sensitive to the sight of blood and the brutality of surgery at the time, so he turned his attention to natural history, an extramural interest he developed when studying at the University of Cambridge to qualify as a ...

Vinchuca
''Triatoma infestans'', commonly called winchuka or vinchuca in Argentina, Bolivia, Uruguay and Chile, barbeiro in Brazil, chipo in Venezuela and also known as "kissing bug" or "barber bug" in English, is a blood-sucking bug (like virtually all the members of its subfamily Triatominae) and the most important vector of ''Trypanosoma cruzi'' which can lead to Chagas disease. It is widespread in the Southern Cone countries of South America. This region has joined the control intervention called ''Southern Cone Initiative'' managed by the PAHO. During the ''Beagle'' survey voyage, Charles Darwin noted in his journal for 26 March 1835 having "experienced an attack, & it deserves no less a name, of the ''Benchuca'', the great black bug of the Pampas. It is most disgusting to feel soft wingless insects, about an inch long, crawling over ones body; before sucking they are quite thin, but afterwards round & bloated with blood, & in this state they are easily squashed."

RÃo De La Plata
The RÃo de la Plata (, "river of silver"), also called the River Plate or La Plata River in English, is the estuary formed by the confluence of the Uruguay River and the Paraná River at Punta Gorda. It empties into the Atlantic Ocean and forms a funnel-shaped indentation on the southeastern coastline of South America. Depending on the geographer, the RÃo de la Plata may be considered a river, an estuary, a gulf, or a marginal sea. If considered a river, it is the widest in the world, with a maximum width of . The river is about long and widens from about at its source to about at its mouth. It forms part of the border between Argentina and Uruguay. The name RÃo de la Plata is also used to refer to the populations along the estuary, especially the main port cities of Buenos Aires and Montevideo, where RÃoplatense Spanish is spoken and tango culture developed. The coasts of the river are the most densely-populated areas of Uruguay and Argentina. Geography The RÃo d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iquique
Iquique () is a port city and commune in northern Chile, capital of both the Iquique Province and Tarapacá Region. It lies on the Pacific coast, west of the Pampa del Tamarugal, which is part of the Atacama Desert. It has a population of 191,468 according to the 2017 census. It is also the main commune of Greater Iquique. The city developed during the heyday of the saltpetre mining in the Atacama Desert in the 19th century. Once a Peruvian city with a large Chilean population, it was conquered by Chile in the War of the Pacific (1879–1883). Today it is one of only two free ports of Chile, the other one being Punta Arenas, in the country's far south. History Although the city was founded in the 16th century, there is evidence of habitation in the area by the Chango people as early as 7,000 BC. During colonial times, Iquique was part of the Viceroyalty of Peru as much of South America was at the time, and remained part of Peruvian territory until the end of the 19th century. Iq ...
