Taxus chinensis is a species of yew. It is commonly called the Chinese yew , though this term also refers to Taxus celebica or Taxus sumatrana .
This plant is used to produce medicines for cancer treatment, [3] [4] including Paclitaxel [5] and Taxifolin (found in Taxus chinensis var. mairei). [6] It can also be used in many other ways and is protected in various ways under Chinese and international law. [4] [7] This protection is in place due to the species' importance to cancer treatment, and its susceptibility to anthropomorphic disturbance. Currently, the species is suffering the consequences of its economic and scientific exploitation for the production of the aforementioned anticancer drugs. [8] [9]
Paclitaxel, sold under the brand name Taxol among others, is a chemotherapy medication used to treat ovarian cancer, esophageal cancer, breast cancer, lung cancer, Kaposi's sarcoma, cervical cancer, and pancreatic cancer. It is administered by intravenous injection. There is also an albumin-bound formulation.
Taxus is a genus of coniferous trees or shrubs known as yews in the family Taxaceae. Yews occur around the globe in temperate zones of the northern hemisphere, northernmost in Norway and southernmost in the South Celebes. Some populations exist in tropical highlands.
Taxaceae, commonly called the yew family, is a coniferous family which includes six extant and two extinct genera, and about 30 species of plants, or in older interpretations three genera and 7 to 12 species.
Alpinia zerumbet, commonly known as shell ginger among other names, is a perennial species of ginger native to East Asia. The plants can grow up to 2.5 to 3 meters tall and bear colorful funnel-shaped flowers. They are grown as ornamentals and their leaves are used in cuisine and traditional medicine.
Taxus brevifolia, the Pacific yew or western yew, is a species of tree in the yew family Taxaceae native to the Pacific Northwest of North America. It is a small evergreen conifer, thriving in moisture and otherwise tending to take the form of a shrub.
Vietnam competed at the 2005 Southeast Asian Games in the Philippines under the IOC country code VIE. By sending a delegation of 516 athletes and competing in 33 out of 40 sports and in 352 out of a total of 439 events, it aimed for a top three placing in the medals table. The final result showed that the Vietnamese team has attained its goal by ranking first in the medal tally with 18 gold, 24 silver and 11 bronze medals. The chief of mission to the games was Nguyen Hong Minh.
Taxanes are a class of diterpenes. They were originally identified from plants of the genus Taxus (yews), and feature a taxadiene core. Paclitaxel (Taxol) and docetaxel (Taxotere) are widely used as chemotherapy agents. Cabazitaxel was FDA approved to treat hormone-refractory prostate cancer.
Taxus canadensis, the Canada yew or Canadian yew, is a conifer native to central and eastern North America, thriving in swampy woods, ravines, riverbanks and on lake shores. Locally called simply "yew", this species is also referred to as American yew or ground-hemlock.
Paclitaxel total synthesis in organic chemistry is a major ongoing research effort in the total synthesis of paclitaxel (Taxol). This diterpenoid is an important drug in the treatment of cancer but, also expensive because the compound is harvested from a scarce resource, namely the Pacific yew. Not only is the synthetic reproduction of the compound itself of great commercial and scientific importance, but it also opens the way to paclitaxel derivatives not found in nature but with greater potential.
Taxus wallichiana, the Himalayan yew, is a species of yew, native to the Himalaya and parts of south-east Asia. The species has a variety of uses in traditional medicine. It is currently classified as endangered by the IUCN.
Taxus floridana, the Florida yew, is a species of yew, endemic to a small area of under 10 km² on the eastern side of the Apalachicola River in mesophytic forests of northern Florida at altitudes of 15–40 m. It is listed as critically endangered. It is protected in reserves at the Torreya State Park and at the Nature Conservancy's Apalachicola Bluffs and Ravines Preserve, and has legal protection under the United States and Florida Endangered Species laws.
Taxus globosa, the Mexican yew, is an evergreen shrub and one of the eight species of yew. The Mexican yew is a rare species, only known to be found in a small number of locations in eastern Mexico, Guatemala, El Salvador and Honduras, and is listed as an endangered species. The Mexican yew is a shrub that grows to an average height of 4.6m. It has large, sharp light green needles growing in ranks on either side of its branches.
Taxifolin (5,7,3',4'-flavan-on-ol), also known as dihydroquercetin, belongs to the subclass flavanonols in the flavonoids, which in turn is a class of polyphenols. It is extracted from plants such as Siberian larch and milk thistle.
Bidoup Nui Ba National Park is a national park in districts of Đam Rông and Lạc Dương, in the province of Lâm Đồng, Vietnam.
Yunnanxane is a bioactive taxane diterpenoid first isolated from Taxus wallichiana. Yunnanxane was later isolated from cell cultures of Taxus cuspidata and Taxus chinensis. Four homologous esters of yunnanxane have also been isolated from Taxus. Yunnanxane is reported to have anticancer activity in vitro.
Nông Thị Xuân (1932–1957) was a mistress of Viet Minh leader Ho Chi Minh, who mothered a child with Hồ and died in a vehicle accident shortly after Xuân was an ethnic Nùng from Cao Bằng Province.
Trichoderma theobromicola is a species of endophytic fungus in the family Hypocreaceae. It was first isolated from the trunk of a healthy cacao tree in Amazonian Peru. It produces a volatile antibiotic that inhibits development of M. roreri.
Trichoderma paucisporum is a species of endophytic fungus in the family Hypocreaceae. It was first isolated in Ecuador from cacao pods infected with frosty pod rot, Moniliophthora roreri. It produces a volatile antibiotic that inhibits development of M. roreri.
Taxus mairei, Maire's yew, is a species of conifer in the yew family Taxaceae, native to Nepal, Assam, central and southern China, Hainan, Taiwan and Vietnam. It is extensively harvested for its paclitaxel (taxol) content in China.
The 8th Central Committee of the Communist Party of Vietnam (CPV) was elected at the 8th CPV National Congress. It elected the 8th Politburo and the 8th Secretariat.
