Acanthospermum Australe
''Acanthospermum australe'' (Paraguayan starburr, ihi kukae hipa, Paraguay bur, Paraquay starbur, pipili, sheepbur, or spiny-bur) is a South American species of herbaceous plants first described as a species in 1758. Distribution The species is native to: * South America, within Brazil, French Guiana, Guyana, Suriname, Venezuela, Argentina, Paraguay, Uruguay, Bolivia, and Colombia * Caribbean, within Grenada; Martinique; St. Vincent, and Grenadines It has been introduced in China, and is an invasive species in parts of the United States, Canada, and South Africa. It is currently a widespread pioneer in the tropics and sub-tropics. Extracts Extracts of ''Acanthospermum australe'' have ''in vitro'' antiviral activity against herpesvirus and poliovirus, but clinical effects have not been studied.

Herpesvirus
''Orthoherpesviridae'', previously named and more widely known as ''Herpesviridae'', is a large family of DNA viruses that cause infections and certain diseases in animals, including humans. The members of this family are commonly known as herpesviruses. The family name is derived from the Greek word ἕρπειν ( 'to creep'), referring to spreading cutaneous lesions, usually involving blisters, seen in flares of herpes simplex 1, herpes simplex 2 and herpes zoster ( shingles). In 1971, the International Committee on the Taxonomy of Viruses (ICTV) established ''Herpesvirus'' as a genus with 23 viruses among four groups. Since then, the number of identified herpesviruses has grown to more than 100. Herpesviruses can cause both latent and lytic infections. Nine herpesvirus types are known to primarily infect humans, at least five of which are extremely widespread among most human populations, and which cause common diseases: herpes simplex 1 and 2 (HSV-1 and HSV-2, also know ...

Flora Of Paraguay
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous (ecology), indigenous) native plant, native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora (mythology), Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and ...

Flora Of Brazil
The wildlife of Brazil comprises all naturally occurring animals, plants, and fungus, fungi in the South American country. Home to 60% of the Amazon Rainforest, which accounts for approximately one-tenth of all species in the world, Brazil is considered to have the greatest biodiversity of any country on the planet. It has the most known species of plants (60,000), freshwater fish (3,000), Amphibian, amphibians (1,188), Snake, snakes (430), Insect, insects (90,000) and mammals (775). It also ranks third on the list of countries with the most bird species (1,971) and the third with the most reptile species (848). The number of fungal species is unknown (+3,300 species).Da Silva, M. and D.W. Minter. 1995. ''Fungi from Brazil recorded by Batista and Co-workers''. Mycological Papers 169. CABI, Wallingford, UK. 585 pp. Approximately two-thirds of all species worldwide are found in tropical areas, often coinciding with developing cou ...

Poliovirus
Poliovirus, the causative agent of polio (also known as poliomyelitis), is a serotype of the species '' Enterovirus C'', in the family of '' Picornaviridae''. There are three poliovirus serotypes, numbered 1, 2, and 3. Poliovirus is composed of an RNA genome and a protein capsid. The genome is a single-stranded positive-sense RNA (+ssRNA) genome that is about 7500 nucleotides long. The viral particle is about 30 nm in diameter with icosahedral symmetry. Because of its short genome and its simple composition—only a strand of RNA and a nonenveloped icosahedral protein coat encapsulating it—poliovirus is widely regarded as the simplest significant virus. Poliovirus is one of the most well-characterized viruses, and has become a useful model system for understanding the biology of RNA viruses. Replication cycle Poliovirus infects human cells by binding to an immunoglobulin-like receptor, CD155 (also known as the poliovirus receptor or PVR) on the cell surface. Inte ...

In Vitro
''In vitro'' (meaning ''in glass'', or ''in the glass'') Research, studies are performed with Cell (biology), cells or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, ''in vivo'' studies are those conducted in living organisms, including humans, known as clinical trials, and whole plants. Definition ''In vitro'' (Latin language, Latin for "in glass"; often not italicized in English usage) studies are conducted ...

Otto Kuntze
Carl Ernst Otto Kuntze (23 June 1843 – 27 January 1907) was a German botanist. Biography Otto Kuntze was born in Leipzig. An apothecary in his early career, he published an essay entitled ''Pocket Fauna of Leipzig''. Between 1863 and 1866, he worked as tradesman in Berlin and traveled through central Europe and Italy. From 1868 to 1873, he had his own factory for essential oils and attained a comfortable standard of living. Between 1874 and 1876, he traveled around the world: the Caribbean, United States, Japan, China, Southeast Asia, Arabian peninsula and Egypt. The journal of these travels was published as "Around the World" (1881). From 1876 to 1878, he studied Natural Science in Berlin and Leipzig and gained his doctorate in Freiburg with a monography of the genus ''Cinchona''. He edited the botanical collection from his world voyage encompassing 7,700 specimens in Berlin and Kew Gardens. The publication came as a shock to botany, since Kuntze had entirely revised taxono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
