Gelsemium Elegans
''Gelsemium elegans'', commonly known as heartbreak grass, is a poisonous plant of the family Gelsemiaceae found in China and other Asian countries. It contains toxic alkaloids such as gelsemine, gelsenicine, gelsevirine and koumine. Crumbled leaves of this plant, surreptitiously added to food, were used in the 23rd of December 2011 poisoning of Long Liyuan, a magnate of the Chinese timber industry, and perhaps in the 10th of November 2012 poisoning of Alexander Perepilichny Alexander Yurevich Perepilichny (russian: Алекса́ндр Ю́рьевич Перепеличный; 15 July 1968 – 10 November 2012) was a Russian businessman and whistleblower who died, while jogging near London in 2012, after leaving Ru ..., a Russian financier cooperating with a fraud investigation in London, though the role of the plant in his death has been disputed.

Poisonous Plant
Plants that produce toxins are referred to as poisonous plants. Plants that cause irritation on contact are also described as "poisonous". The toxins in poisonous plants affect herbivores, and deter them from consuming the plants. Plants cannot move to escape their predators, so they must have other means of protecting themselves from herbivorous animals. Some plants have physical defenses such as thorns, spines and prickles, but by far the most common type of protection is chemical. Over millennia, through the process of natural selection, plants have evolved the means to produce a vast and complicated array of chemical compounds to deter herbivores. Tannin, for example, is a defensive compound that emerged relatively early in the evolutionary history of plants, while more complex molecules such as polyacetylenes are found in younger groups of plants such as the Asterales. Many of the known plant defense compounds primarily defend against consumption by insects, though other a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gelsemiaceae
Gelsemiaceae is a family of flowering plants, belonging to the order Gentianales. The family contains only three genera: ''Gelsemium'', ''Mostuea'' and ''Pteleocarpa''. ''Gelsemium'' has three species, one native to Southeast Asia and southern China and two native to Central America, Mexico, and the southeastern United States. The eight species of ''Mostuea'' are native to tropical areas of South America, Africa, and Madagascar. The two genera were formerly classified in the family Loganiaceae.Peter F. Stevens (2001 onwards). "Gelsemiaceae" At: Angiosperm Phylogeny Website. At: Botanical Databases At: Missouri Botanical Garden Website. (see ''External links'' below) ''Pteleocarpa'' was originally placed in Boraginaceae or in its own family Pteleocarpaceae, but it is most closely related to Gelsemiaceae with which it shares significant characters. The family Gelsemiaceae was described in 1994.Lena Struwe, Victor A. Albert, and Birgitta Bremer. 1994. "Cladistics and family level ...

Alkaloid
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , Medicinal plant, plants, an ...

Gelsemine
Gelsemine (C20H22N2O2) is an indole alkaloid isolated from flowering plants of the genus ''Gelsemium sempervirens, Gelsemium'', a plant native to the subtropical and tropical Americas, and southeast Asia, and is a highly toxic compound that acts as a paralytic, exposure to which can result in death. It has generally potent activity as an agonist of the mammalian glycine receptor, the activation of which leads to an inhibitory postsynaptic potential in neurons following chloride ion influx, and systemically, to muscle relaxation of varying intensity and deleterious effect. Despite its danger and toxicity, recent pharmacological research has suggested that the biological activities of this compound may offer opportunities for developing treatments related to xenobiotic or diet-induced oxidative stress, and of anxiety and other conditions, with ongoing research including attempts to identify safer derivatives and analogs to make use of gelsemine's beneficial effects.

Alexander Perepilichny
Alexander Yurevich Perepilichny (russian: Алекса́ндр Ю́рьевич Перепеличный; 15 July 1968 – 10 November 2012) was a Russian businessman and whistleblower who died, while jogging near London in 2012, after leaving Russia in 2009. However, the inquest into his death continues. A British cardiologist employed by the court has concluded he probably died of natural causes. He was alleged to have been killed as part of the conspiracy to cover up the theft of $230 million from the . Career In December 2007, Perepilichny's Quartell Trading signed a contract to buy $3,172,000 worth of "furniture", from Balec Ventures, a company owned by Issa al-Zeydi, who is a Russian of Syrian descent sanctioned by the U.S. Treasury Department in 2014, due to his connection to the Syrian Scientific Studies and Research Center, Scientific Studies and Research Center in Syria.

Agence France-Presse
Agence France-Presse (AFP) is a French international news agency headquartered in Paris, France. Founded in 1835 as Havas, it is the world's oldest news agency. AFP has regional headquarters in Nicosia, Montevideo, Hong Kong and Washington, D.C., and news bureaus in 151 countries in 201 locations.

History Agence France-Presse has its origins in the Agence Havas, founded in 1835 in Paris by Charles-Louis Havas, making it the world's oldest news service. The agency pioneered the collection and dissemination of news as a commodity, and had established itself as a fully global concern by the late 19th century. Two Havas employees, Paul Julius Reuter and Bernhard Wolff, set up their own news agencies in London and Berlin respectively. In 1940, when German forces occupied France during World War II, the news agency was taken over by the authorities and renamed "Office fr ...

ABC Online
The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a televi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
