Chuquiraga Spinosa
''Chuquiraga spinosa'', common name in Spanish, is a species of flowering plant of the family Asteraceae. Native to Perú and Bolivia, it is used in traditional medicine for its anti-inflammatory properties. Taxonomy ''Chuquiraga spinosa'' was described by Christian Friedrich Lessing and published in Linnaea 5: 259, in 1830. Economic and cultural importance It is used in traditional medicine in Peru as a cleanser, a diuretic, and to treat kidney, liver, and prostate inflammation. Secondary metabolites The presence of phenolic acids, flavonoids, saponins, alkaloids, tannins, and steroids has been identified in the ethanolic extract of the aerial parts of the plant. Scientific studies ''In vitro'' studies in 2005 in Lima have determined the antioxidant properties of 53 ethanolic extracts of 40 plants used in traditional Peruvian medicine from different parts of the plants (root, flowers, stems, leaves, bark). The antioxidant activity of 21 of the extracts was demonstrated, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Friedrich Lessing
Christian Friedrich Lessing (10 August 1809 – 13 March 1862) was a German botanist who was a native of Groß Wartenberg, Niederschlesien. He was a brother to painter Carl Friedrich Lessing (1808–1880), and a grandnephew of poet Gotthold Ephraim Lessing (1729–1781). Lessing was a botanical authority on the plant family Asteraceae, and in 1832 published an influential treatise on Asteraceae called ''Synopsis generum Compositarum''. He performed extensive botanical research in Siberia. In 1862 he was buried in Trinity Cemetery, in the Siberian city of Krasnoyarsk. The plant genus ''Lessingia'' from the family Asteraceae is named in honor of Christian Friedrich, Karl Friedrich and Gotthold Ephraim Lessing Gotthold Ephraim Lessing (, ; 22 January 1729 – 15 February 1781) was a philosopher, dramatist, publicist and art critic, and a representative of the Enlightenment era.

The DU145 cell line was derived from a central nervous system metastasis, of primary prostate adenocarcinoma origin, removed during a parieto-occipital craniotomy. DU145 are not hormone-sensitive and do not express prostate-specific antigen (PSA). DU145 cells have moderate metastatic potential compared to PC3 cells, which have high metastatic potential. DU145 cells are androgen receptor positive. References External links Cellosaurus entry for DU145 Human cell lines Cancer research Urology Prostate cancer {{cell-biology-stub ...

Flora Of Bolivia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) 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''. Etymology The word "flora" comes from the Latin name of 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 (the taxonomic composition of a community) was first made by Jules Thurm ...

Barnadesioideae
Barnadesioideae is a subfamily of flowering plants in the aster family, Asteraceae. It comprises a single tribe, the Barnadesieae. The subfamily is endemic to South America.

ResearchGate
ResearchGate is a European commercial social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators. According to a 2014 study by ''Nature'' and a 2016 article in '' Times Higher Education'', it is the largest academic social network in terms of active users, although other services have more registered users, and a 2015–2016 survey suggests that almost as many academics have Google Scholar profiles. While reading articles does not require registration, people who wish to become site members need to have an email address at a recognized institution or to be manually confirmed as a published researcher in order to sign up for an account. Members of the site each have a user profile and can upload research output including papers, data, chapters, negative results, patents, research proposals, methods, presentations, and software source code. Users may also follow the activities of other users and engage in discussions with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity Heritage Library
The Biodiversity Heritage Library (BHL) is the world’s largest open access digital library for biodiversity literature and archives.

The Plant List
The Plant List was a list of botanical names of species of plants created by the Royal Botanic Gardens, Kew and the Missouri Botanical Garden and launched in 2010. It was intended to be a comprehensive record of all known names of plant species over time, and was produced in response to Target 1 of the 2002-2010 Global Strategy for Plant Conservation (GSP C), to produce "An online flora of all known plants.” It has not been updated since 2013, and has been superseded by World Flora Online. World Flora Online In October 2012, the follow-up project World Flora Online was launched with the aim to publish an online flora of all known plants by 2020. This is a project of the United Nations Convention on Biological Diversity, with the aim of halting the loss of plant species worldwide by 2020. It is developed by a collaborative group of institutions around the world response to the 2011-2020 GSPC's updated Target 1. This aims to achieve an online Flora of all known plants by 2020 ...

N-Methyl-N-nitrosourea
''N''-Nitroso-''N''-methylurea (NMU) is a highly reliable carcinogen, mutagen, and teratogen. NMU is an alkylating agent, and exhibits its toxicity by transferring its methyl group to nucleobases in nucleic acids, which can lead to AT:GC transition mutations. NMU is the traditional precursor in the synthesis of diazomethane. It has the potentially advantageous property that the stoichiometric byproducts formed are water, carbon dioxide, and ammonia, which are innocuous or easily removed. However, because it is unstable at temperatures beyond 20 °C and somewhat shock-sensitive, it has become obsolete for this purpose and replaced by other N-nitroso compounds: (''N''-methyl)nitrosamides and nitrosamines. Most chemical supply houses have stopped carrying it. Acute exposure to NMU in humans can result in skin and eye irritation, headache, nausea, and vomiting.

Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is often contrasted with scientific medicine. In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside its traditional culture, traditional medicine is often considered a form of alternative medicine. Practices known as traditional medi ...
