Anogeissus Leiocarpus
''Anogeissus leiocarpa'' (African birch; bm, ngálǎma) is a tall deciduous tree native to the savannas of tropical Africa. It is the sole West African species of the genus ''Anogeissus'', a genus otherwise distributed from tropical central and east Africa through tropical Southeast Asia. ''Anogeissus leiocarpa'' germinates in the new soils produced by seasonal wetlands. It is a forest fringe plant, growing at the edges of the rainforest, although not deep in the rainforest. It also grows in savanna, and along riverbanks, where it forms gallery forests. The tree flowers in the rainy season, from June to October. The fruit are winged samaras, and are dispersed by ants. Ethnobotany It is one of the plants used to make ''bògòlanfini'', a traditional Malian mudcloth. Small branches with leaves are crushed to make one of the yellow dyes. The inner bark of the tree is used as a human and livestock anthelmintic for treating worms, and for treatment of a few protozoa ...

Castalagin
Castalagin is an ellagitannin, a type of hydrolyzable tannin, found in oak and chestnut wood and in the stem barks of ''Anogeissus leiocarpus'' and ''Terminalia avicennoides''. Castalagin is the diastereomer of vescalagin in C-1 of the glycosidic chain. Castalagin/ vescalagin are the most abundant ellagitannins in white wine stored in oak barrels. During aging of wines, these two compounds were progressively extracted from the wood and were transformed into new derivatives by chemical reactions. Therefore, castalagin/ vescalagin and their derivatives contribute to the color and the taste of wines and spirits stored in oak barrels. Sources Castalagin was first isolated in Fagaceae family woody species : ''Quercus'' (oak) and '' Castanea'' (chestnut) by Walter Mayer and co-workers (1967). In some chestnut species, such as ''Castanea sativa'', heartwood could contain 63 mg of castalagin/ vescalagin per gram of dry wood. In some wines, these two isomers represent about 40 to 70% ...

Antibacterial
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity. Antibiotics are not effective against viruses such as the common cold or influenza; drugs which inhibit viruses are termed antiviral drugs or antivirals rather than antibiotics. Sometimes, the term ''antibiotic''—literally "opposing life", from the Greek roots ἀντι ''anti'', "against" and βίος ''bios'', "life"—is broadly used to refer to any substance used against microbes, but in the usual medical usage, antibiotics (such as penicillin) are those produced naturally (by one microorganism fighting another), whereas non-antibiotic antibacterials (such as sulfonamides and antiseptics) ar ...

Babesiosis
Babesiosis or piroplasmosis is a malaria-like parasitic disease caused by infection with a eukaryotic parasite in the order Piroplasmida, typically a ''Babesia'' or ''Theileria'', in the phylum Apicomplexa. Human babesiosis transmission via tick bite is most common in the Northeastern and Midwestern United States and parts of Europe, and sporadic throughout the rest of the world. It occurs in warm weather. People can get infected with ''Babesia'' parasites by the bite of an infected tick, by getting a blood transfusion from an infected donor of blood products, or by congenital transmission (an infected mother to her baby). Ticks transmit the human strain of babesiosis, so it often presents with other tick-borne illnesses such as Lyme disease. After trypanosomes, ''Babesia'' is thought to be the second-most common blood parasite of mammals. They can have major adverse effects on the health of domestic animals in areas without severe winters. In cattle the disease is known as T ...

Trypanosomiasis
Trypanosomiasis or trypanosomosis is the name of several diseases in vertebrates caused by parasitic protozoan trypanosomes of the genus ''Trypanosoma''. In humans this includes African trypanosomiasis and Chagas disease. A number of other diseases occur in other animals. African trypanosomiasis, which is caused by either ''Trypanosoma brucei gambiense'' or ''Trypanosoma brucei rhodesiense'', threatens some 65 million people in sub-Saharan Africa, especially in rural areas and populations disrupted by war or poverty. The number of cases has been going down due to systematic eradication efforts: in 1998 almost 40,000 cases were reported but almost 300,000 cases were suspected to have occurred; in 2009, the number dropped below 10,000; and in 2018 it dropped below 1000. Chagas disease causes 21,000 deaths per year mainly in Latin America. Signs and symptoms The tsetse fly bite erupts into a red chancre sore and within a few weeks, the person can experience fever, swollen lymph gla ...

Nagana
Animal trypanosomiasis, also known as nagana and nagana pest, or sleeping sickness, is a disease of vertebrates. The disease is caused by trypanosomes of several species in the genus ''Trypanosoma'' such as ''Trypanosoma brucei''. ''Trypanosoma vivax'' causes nagana mainly in West Africa, although it has spread to South America. The trypanosomes infect the blood of the vertebrate host, causing fever, weakness, and lethargy, which lead to weight loss and anemia; in some animals the disease is fatal unless treated. The trypanosomes are transmitted by tsetse flies. An interesting feature is the remarkable tolerance to nagana pathology shown by some breeds of cattle, notably the N'Dama – a West African ''Bos taurus'' breed. This contrasts with the susceptibility shown by East African '' Bos indicus'' cattle such as the zebu. Transmission Most trypanosomes develop in tsetse flies (''Glossina'' spp.), its biological vector, in about one to a few weeks. When an infected tsetse fly b ...

Protozoan
Protozoa (singular: protozoan or protozoon; alternative plural: protozoans) are a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris. Historically, protozoans were regarded as "one-celled animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae. When first introduced by Georg Goldfuss (originally spelled Goldfuß) in 1818, the taxon Protozoa was erected as a class within the Animalia, with the word 'protozoa' meaning "first animals". In later classification schemes it was elevated to a variety of higher ranks, including phylum, subkingdom and kingdom, and sometimes included within Protoctista or Protista. The approach of classifying Protozoa within the context of Animalia was widespread in the 19th and early 20th century, but not universal. By the 1970s, it became usual to require th ...

Anthelmintic
Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. They may also be called vermifuges (those that stun) or vermicides (those that kill). Anthelmintics are used to treat people who are infected by helminths, a condition called helminthiasis. These drugs are also used to treat infected animals. Pills containing anthelmintics are used in mass deworming campaigns of school-aged children in many developing countries. The drugs of choice for soil-transmitted helminths are mebendazole and albendazole; for schistosomiasis and tapeworms it is praziquantel. Types Antiparasitics that specifically target worms of the genus ''Ascaris'' are called ascaricides. * Benzimidazoles: ** Albendazole – effective against threadworms, roundworms, whipworms, tapeworms, hookworms ** Mebendazole – effective against v ...

Bògòlanfini
Bògòlanfini or bogolan ( bm, bɔgɔlanfini; "mud cloth"; sometimes called mud-dyed cloth or mud-painted cloth in English) is a handmade Malian cotton fabric traditionally dyed with fermented mud. It has an important place in traditional Malian culture and has, more recently, become a symbol of Malian cultural identity. The cloth is exported worldwide for use in fashion, fine art and decoration. Origins and etymology The dye technique is associated with several Malian ethnic groups, but the Bamana version has become best known outside Mali. In the Bambara language, the word ''bògòlanfini'' is a composite of ''bɔgɔ'', meaning "earth" or "mud"; ''lan'', meaning "with" or "by means of"; and ''fini'', meaning "cloth". Although usually translated as "mud cloth," ''bògòlan'' actually refers to slip clay with a high iron content. The iron in the clay will stain handspun and handwoven cotton textiles black. Production The center of bògòlanfini production, and the source ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
