Nigerian Seasonal Ataxia
''Anaphe venata'' is a moth of the family Notodontidae. It was described by Arthur Gardiner Butler in 1878. It lives in Angola, Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Equatorial Guinea, Ghana, Ivory Coast, Nigeria, Tanzania and Togo. The larvae have been recorded feeding on ''Triplochiton scleroxylon'', ''Cola verticillata'' and ''Cola ballayi''. Eating ''A. venata'' larvae (entomophagy) has led to thiamine deficiency Thiamine deficiency is a medical condition of low levels of thiamine (Vitamin B1). A severe and chronic form is known as beriberi. The two main types in adults are wet beriberi and dry beriberi. Wet beriberi affects the cardiovascular system, r ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Ghana
Ghana (; tw, Gaana, ee, Gana), officially the Republic of Ghana, is a country in West Africa. It abuts the Gulf of Guinea and the Atlantic Ocean to the south, sharing borders with Ivory Coast in the west, Burkina Faso in the north, and Togo in the east.Jackson, John G. (2001) ''Introduction to African Civilizations'', Citadel Press, p. 201, . Ghana covers an area of , spanning diverse biomes that range from coastal savannas to tropical rainforests. With nearly 31 million inhabitants (according to 2021 census), Ghana is the List of African countries by population, second-most populous country in West Africa, after Nigeria. The capital and List of cities in Ghana, largest city is Accra; other major cities are Kumasi, Tamale, Ghana, Tamale, and Sekondi-Takoradi. The first permanent state in present-day Ghana was the Bono state of the 11th century. Numerous kingdoms and empires emerged over the centuries, of which the most powerful were the Kingdom of Dagbon in the north and ...

Thiaminase
Thiaminase is an enzyme that metabolizes or breaks down thiamine into two molecular parts. It is an antinutrient when consumed. The old name was "aneurinase". There are two types: * Thiamine pyridinylase, Thiaminase I (, ) * Aminopyrimidine aminohydrolase, Thinaminase II (, , ) Sources Source include: * Bracken (brake), nardoo, horsetail, and other plants. * Some fish including carp and goldfish. * A few strains of bacteria such as '' Paenibacillus thiaminolyticus'' (''Bacillus thiaminolyticus''), '' Bacillus aneurinolyticus'', or ''Bacillus subtilis''. * An African silk worm, ''Anaphe venata'' Effects Its physiological role for fish, bacterial cell or insect is not known. However, in ferns it is thought to offer protection from insects while studies have shown that thiamine hydrolase (thiaminase type 2) which was originally thought to be involved solely in the degradation of thiamine has actually been identified as having a role in thiamine degradation with the salvage of th ...

Protein (nutrient)
Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates: 4 kcal (17 kJ) per gram; in contrast, lipids provide 9 kcal (37 kJ) per gram. The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition. Proteins are polymer chains made of amino acids linked together by peptide bonds. During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via hydrochloric acid and protease actions. This is crucial for the absorption of the essential amino acids that cannot be biosynthesized by the body. There are nine essential amino acids which humans must obtain from their diet in order to prevent protein–energy malnutrition and resulting death. They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Thiamine Deficiency
Thiamine deficiency is a medical condition of low levels of thiamine (Vitamin B1). A severe and chronic form is known as beriberi. The two main types in adults are wet beriberi and dry beriberi. Wet beriberi affects the cardiovascular system, resulting in a fast heart rate, shortness of breath, and leg swelling. Dry beriberi affects the nervous system, resulting in numbness of the hands and feet, confusion, trouble moving the legs, and pain. A form with loss of appetite and constipation may also occur. Another type, acute beriberi, found mostly in babies, presents with loss of appetite, vomiting, lactic acidosis, changes in heart rate, and enlargement of the heart. Risk factors include a diet of mostly white rice, alcoholism, dialysis, chronic diarrhea, and taking high doses of diuretics. In rare cases, it may be due to a genetic condition that results in difficulties absorbing thiamine found in food. Wernicke encephalopathy and Korsakoff syndrome are forms of dry beriberi. ...

Entomophagy
Entomophagy (, from Greek ἔντομον ', 'insect', and φαγεῖν ', 'to eat') is the practice of eating insects. An alternative term is insectivory. Terms for organisms that practice entomophagy are ''entomophage'' and ''insectivore''. Entomophagy is sometimes defined to also include the eating of arthropods other than insects, such as arachnids and myriapods; eating arachnids may also be referred to as arachnophagy. In non-humans Entomophagy is widespread among many animals, including non-human primates. Animals that feed primarily on insects are called insectivores. Insects, nematodes and fungi that obtain their nutrition from insects are sometimes termed ''entomophagous'', especially in the context of biological control applications. These may also be more specifically classified into predators, parasites or parasitoids, while viruses, bacteria and fungi that grow on or inside insects may also be termed ''entomopathogenic'' (see also entomopathogenic fungi). ...

Cola Ballayi
Cola is a carbonated soft drink flavored with vanilla, cinnamon, citrus oils and other flavorings. Cola became popular worldwide after the American pharmacist John Stith Pemberton invented Coca-Cola, a trademarked brand, in 1886, which was imitated by other manufacturers. Most colas contain caffeine originally from the kola nut, leading to the drink's name, though other sources have since been used. The Pemberton cola drink also contained a coca plant extract. His non-alcoholic recipe was inspired by the coca wine of pharmacist Angelo Mariani, created in 1863. Most modern colas have a dark caramel color, and are sweetened with sugar and/or high-fructose corn syrup. They come in numerous different brands. with Coca-Cola and Pepsi being among the most popular. These two companies have been competing since the 1890s, a rivalry that has intensified since the 1980s. Flavorings The primary modern flavorings in a cola drink are citrus oils (from orange, lime, and lemon peels), ci ...
