Common names include African mahogany, dry zone mahogany, Gambia mahogany, khaya wood, Senegal mahogany, ''cailcedrat'', ''acajou'', ''djalla'', and ''bois rouge''. Description African mahogany is a fast-growing medium-sized tree which can obtain a height of up to 15–30 m in height and 1 m in diameter. The bark is dark grey to grey-brown while the heartwood is brown with a pink-red pigment made up of coarse interlocking grains.

Hanoi
Hanoi or Ha Noi ( or ; vi, Hà Nội ) is the capital and second-largest city of Vietnam. It covers an area of . It consists of 12 urban districts, one district-leveled town and 17 rural districts. Located within the Red River Delta, Hanoi is the cultural and political centre of Vietnam. Hanoi can trace its history back to the third century BCE, when a portion of the modern-day city served as the capital of the historic Vietnamese nation of Âu Lạc. Following the collapse of Âu Lạc, the city was part of Han China. In 1010, Vietnamese emperor Lý Thái Tổ established the capital of the imperial Vietnamese nation Đại Việt in modern-day central Hanoi, naming the city Thăng Long (literally 'Ascending Dragon'). Thăng Long remained Đại Việt's political centre until 1802, when the Nguyễn dynasty, the last imperial Vietnamese dynasty, moved the capital to Huế. The city was renamed Hanoi in 1831, and served as the capital of French Indochina from 1902 to 1945. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trypanosoma Brucei Brucei
''Trypanosoma brucei'' is a species of parasitic kinetoplastid belonging to the genus ''Trypanosoma'' that is present in sub-Saharan Africa. Unlike other protozoan parasites that normally infect blood and tissue cells, it is exclusively extracellular and inhabits the blood plasma and body fluids. It causes deadly vector-borne diseases: African trypanosomiasis or sleeping sickness in humans, and animal trypanosomiasis or ''nagana'' in cattle and horses. It is a species complex grouped into three subspecies: ''T. b. brucei'', ''T. b. gambiense'' and ''T. b. rhodesiense''. The first is a parasite of non-human mammals and causes ''nagana'', while the latter two are zoonotic infecting both humans and animals and cause African trpanosomiasis. ''T. brucei'' is transmitted between mammal hosts by an insect vector belonging to different species of tsetse fly (''Glossina''). Transmission occurs by biting during the insect's blood meal. The parasites undergo complex morphological changes as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trypanosoma Congolense
''Trypanosoma congolense'' is a species of trypanosomes and is the major pathogen responsible for the disease nagana in cattle and other animals including sheep, pigs, goats, horses and camels, dogs, as well as laboratory mice. It is the most common cause of nagana in east Africa, but is also a major cause of nagana in west Africa. This parasite is spread by tsetse flies. In its mammalian host, ''Trypanosoma congolense'' only lives in blood vessels, and causes in particular anaemia. , USAHA gray book, 6th ed. (1998). Infection process ''T. congolense'' causes .

Trypanosoma Evansi
''Trypanosoma evansi'' is a parasitic species of excavate trypanosome in the genus ''Trypanosoma'' that causes one form of surra in animals. Discovered by Griffith Evans in 1880 at Dera Ismail Khan (British India), it is the first known trypanosome that causes infection. It is a common parasite in India and Iran and causes acute disease in camels and horses, and chronic disease in cattle and buffalo. In Pakistan, it has been found to be the most prevalent trypanosome species in donkeys. It is now established to infect other mammals, including humans. It has been proposed that ''T. evansi'' is—like '' T. equiperdum''—a derivative of '' T. brucei''. Due to the loss of part of the mitochondrial (kinetoplast) DNA ''T. evansi'' is not capable of infecting tsetse flies, the usual invertebrate vectors of trypanosomes, and establishing the subsequent life-stages. Due to its mechanical transmission ''T. evansi'' shows a very broad vector specificity including members of the gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stem Bark
Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost layer of the periderm. The outer bark on older stems includes the dead tissue on the surface of the stems, along with parts of the outermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees which lies external to the living periderm is also called the rhytidome. Products derived from bark include bark shingle siding and wall coverings, spices and other flavorings, tanbark for tannin, resin, latex, medicines, poisons, various hallucinogenic chemicals and cork. Bark has been used to make cloth, canoes, and ropes and used as a surface for paintings and map making. A number of plants are ...

Extract
An extract is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol, oil or water. Extracts may be sold as tinctures, absolutes or in powder form. The aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange, peppermint, pistachio, rose, spearmint, vanilla, violet, rum, and wintergreen. Extraction techniques Most natural essences are obtained by extracting the essential oil from the feedstock, such as blossoms, fruit, and roots, or from intact plants through multiple techniques and methods: * Expression (juicing, pressing) involves physical extraction material from feedstock, used when the oil is plentiful and easily obtained from materials such as citrus peels, olives, and grapes. * Absorption (steeping, decoction). Extraction is done by soaking material in a solvent, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trypanocidal
A trypanocidal agent is an antiprotozoal agent that acts upon trypanosome parasites. Examples include: * Aminoquinuride * benzonidazole * blasticidin S * DAPI * diminazene * diminazene aceturate * eflornithine * ethidium * isometamidium chloride * lonidamine * melaminylthioarsenate * melarsoprol * nifurtimox * pentamidine * posaconazole * puromycin * quinapyramine * salicylhydroxamic acid * suramin * tetraphenylporphine sulfonate Resistance 17 or 18 African countries had confirmed resistant parasite populations, and that was up to 21. Multiply resistant populations are an increasing problem in the Adamawa Region of Cameroon and south east Mali. The Gibe River Valley in southwest Ethiopia showed universal resistance (in '' T. congolense'' isolated from Boran cattle) between July 1989 and February 1993. This likely indicates a permanent loss of function in this area for the tested trypanocides, Diminazene aceturate, Isometamidium chloride, and Homidium chloride. See a ...

Togo
Togo (), officially the Togolese Republic (french: République togolaise), is a country in West Africa. It is bordered by Ghana to the west, Benin to the east and Burkina Faso to the north.

From the 11th to the 16th century, tribes entered the region from various directions. From the 16th century to the 18th century, the coastal region was a trading center for Europeans to purchase slaves, earning Togo and the surrounding region the name "The Slave Coast". In 1884, Germany declared a region including a protectorate called Togoland. After World War I, rule over Togo was transferred to France. Togo gained its independence from France in 1960.
