Corydalis Ambigua
''Corydalis ambigua'' is a tuberous early flowering east Asian flowering plant species in the poppy family Papaveraceae. Its exact native range is obscure due to taxonomic confusion. It is one of the sources of the drug tetrahydropalmatine. Chemistry ''Corydalis ambigua'' contains a variety of alkaloids including corynoline, acetylcorynoline d-corydalin, dl-tetrahydropalmatine, protopine, tetrahydrocoptisine, dl-tetrahydrocoptisine, d-corybulbine and allocryptopine. Chemical derivatives of tetrahydroprotoberberines present in ''Corydalis ambigua'' have been studied as potential ways to increase pain tolerance and for treating drug addiction. Further, they may represent a category of neurotransmitter stabilizers which have potential use in broad range of psychotic and neurological disorders. Use ''Cordyalis ambigua'' is part of the traditional Ainu cuisine: See also *Chinese herbology Chinese herbology () is the theory of traditional Chinese herbal thera ...

Adelbert Von Chamisso
Adelbert von Chamisso (; 30 January 178121 August 1838) was a German poet and botanist, author of ''Peter Schlemihl'', a famous story about a man who sold his shadow. He was commonly known in French as Adelbert de Chamisso (or Chamissot) de Boncourt, a name referring to the family estate at Boncourt. Life The son of Louis Marie, Count of Chamisso, by his marriage to Anne Marie Gargam, Chamisso began life as Louis Charles Adélaïde de Chamissot at the ''château'' of Boncourt at Ante, in Champagne, France, the ancestral seat of his family. His name appears in several forms, one of the most common being ''Ludolf Karl Adelbert von Chamisso.''Rodolfo E.G. Pichi Sermolli. 1996. ''Authors of Scientific Names in Pteridophyta''. Royal Botanic Gardens, Kew. In 1790, the French Revolution drove his parents out of France with their seven children, and they went successively to Liège, the Hague, Würzburg, and Bayreuth, and possibly Hamburg, before settling in Berlin. There, in 179 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
50 Fundamental Herbs
Chinese herbology () is the theory of traditional Chinese herbal therapy, which accounts for the majority of treatments in traditional Chinese medicine (TCM). A ''Nature'' editorial described TCM as "fraught with pseudoscience", and said that the most obvious reason why it has not delivered many cures is that the majority of its treatments have no logical mechanism of action. The term herbology is misleading in the sense that, while plant elements are by far the most commonly used substances, animal, human, and mineral products are also utilized, among which some are poisonous. In the ''Huangdi Neijing'' they are referred to as () which means toxin, poison, or medicine. Paul U. Unschuld points out that this is similar etymology to the Greek '' pharmakon'' and so he uses the term "pharmaceutic". Thus, the term "medicinal" (instead of herb) is usually preferred as a translation for (). Research into the effectiveness of traditional Chinese herbal therapy is of poor quality an ...

Southern Kuriles
The Kuril Islands dispute, known as the Northern Territories dispute in Japan, is a territorial dispute between Japan and Russia over the ownership of the four southernmost Kuril Islands. The Kuril Islands are a chain of islands that stretch between the Japanese island of Hokkaido at their southern end and the Russian Kamchatka Peninsula at their northern end. The islands separate the Sea of Okhotsk from the Pacific Ocean. The four disputed islands, like other islands in the Kuril chain that are not in dispute, were unilaterally annexed by the Soviet Union following the Kuril Islands landing operation at the end of World War II. The disputed islands are under Russian administration as the South Kuril District and part of Kuril District of the Sakhalin Oblast (Сахалинская область, ''Sakhalinskaya oblast''). They are claimed by Japan, which refers to them as its Northern Territories or Southern Chishima, and considers them part of the Nemuro Subprefecture of ...

Saghalien
Sakhalin ( rus, Сахали́н, r=Sakhalín, p=səxɐˈlʲin; ja, 樺太 ''Karafuto''; zh, c=, p=Kùyèdǎo, s=库页岛, t=庫頁島; Manchu: ᠰᠠᡥᠠᠯᡳᠶᠠᠨ, ''Sahaliyan''; Orok: Бугата на̄, ''Bugata nā''; Nivkh: Yh-mif) is the largest island of Russia. It is north of the Japanese archipelago, and is administered as part of the Sakhalin Oblast. Sakhalin is situated in the Pacific Ocean, sandwiched between the Sea of Okhotsk to the east and the Sea of Japan to the west. It is located just off Khabarovsk Krai, and is north of Hokkaido in Japan. The island has a population of roughly 500,000, the majority of which are Russians. The indigenous peoples of the island are the Ainu, Oroks, and Nivkhs, who are now present in very small numbers. The Island's name is derived from the Manchu word ''Sahaliyan'' (ᠰᠠᡥᠠᠯᡳᠶᠠᠨ). Sakhalin was once part of China during the Qing dynasty, although Chinese control was relaxed at times. Sakhalin was l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ishikari River
The , at long, is the third longest in Japan and the longest in Hokkaidō. The river drains an area of , making it the second largest in Japan, with a total discharge of around per year. It originates from Mount Ishikari in the Daisetsuzan Volcanic Group and flows through Asahikawa and Sapporo. Major tributaries of the river include the Chūbetsu, Uryū, Sorachi and Toyohira rivers. Until 40,000 years ago, it flowed into the Pacific Ocean near Tomakomai. Lava from the volcanic Shikotsu mountains dammed the river and moved its mouth to the Ishikari Bay. The name of the river is derived from the Ainu for "make(s) itself go round about something" (''i-si-kari'' < ''kari'' meaning "(to be a) circle, round, loop; spin, turn, go around, go back and forth," ''si-'' "reflexive prefix, itself, oneself," and ''i-'' "it, something, an impersonal third person object marking prefix, middle voice inflection prefix), ''i.e.'' "winding (river)."

Ainu People
The Ainu are the indigenous people of the lands surrounding the Sea of Okhotsk, including Hokkaido Island, Northeast Honshu Island, Sakhalin Island, the Kuril Islands, the Kamchatka Peninsula and Khabarovsk Krai, before the arrival of the Yamato Japanese and Russians. These regions are referred to as in historical Japanese texts. Official estimates place the total Ainu population of Japan at 25,000. Unofficial estimates place the total population at 200,000 or higher, as the near-total assimilation of the Ainu into Japanese society has resulted in many individuals of Ainu descent having no knowledge of their ancestry. As of 2000, the number of "pure" Ainu was estimated at about 300 people. In 1966, there were about 300 native Ainu speakers; in 2008, however, there were about 100. Names This people's most widely known ethnonym, "Ainu" ( ain, ; ja, アイヌ; russian: Айны) means "human" in the Ainu language, particularly as opposed to , divine beings. Ainu also i ...

Derivative (chemistry)
In chemistry, a derivative is a compound that is derived from a similar compound by a chemical reaction. In the past, derivative also meant a compound that ''can be imagined to'' arise from another compound, if one atom or group of atoms is replaced with another atom or group of atoms, but modern chemical language now uses the term structural analog for this meaning, thus eliminating ambiguity. The term "structural analogue" is common in organic chemistry. In biochemistry, the word is used for compounds that at least theoretically can be formed from the precursor compound. Chemical derivatives may be used to facilitate analysis. For example, melting point (MP) analysis can assist in identification of many organic compounds. A crystalline derivative may be prepared, such as a semicarbazone or 2,4-dinitrophenylhydrazone (derived from aldehydes or ketones), as a simple way of verifying the identity of the original compound, assuming that a table of derivative MP values is available ...

Diederich Franz Leonhard Von Schlechtendal
Diederich Franz Leonhard von Schlechtendal (27 November 1794, Xanten – 12 October 1866, Halle) was a German botanist. He studied in Berlin, in 1819 becoming curator of the Royal Herbarium. He was a professor of botany and director of the Botanical Gardens at the Martin Luther University of Halle-Wittenberg from 1833 until his death in 1866. The genus '' Schlechtendalia'' (Asteraceae), from Brazil, Uruguay and Argentina, was named in his honor. He was editor of the botanical journal ''Linnaea'' (from 1826), and with Hugo von Mohl (1805-1872), was publisher of the ''Botanischen Zeitung'' (from 1843). He conducted important investigations of the then largely unknown flora of Mexico, carried out in conjunction with Adelbert von Chamisso (1781-1838), and based on specimens collected by Christian Julius Wilhelm Schiede (1798-1836) and Ferdinand Deppe (1794-1861). Schlechtendal was a critic of Darwinism but accepted a limited form of evolution. He advocated a form common desce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
