Cubé Resin
''Lonchocarpus'' is a plant genus in the legume family (Fabaceae). It includes 166 species native to the tropical Americas, tropical Africa, and Madasgascar. The species are called lancepods due to their fruit resembling an ornate lance tip or a few beads on a string. ''Cubé'' resin is produced from the roots of '' L. urucu'' and namely ' L. utilis'' (''cubé''). It contains enough of the toxic rotenoids rotenone and deguelin to be used as an insecticide and piscicide. As these are naturally occurring compounds, they were formerly used in organic farming. Since it is highly unselective and kills useful, as well as pest, animals, it is considered harmful to the environment today. Also, chronic exposure to rotenone and deguelin appears to increase the risk of Parkinson's disease, even in mammals, for which these compounds are less immediately toxic than for fish and insects. Deguelin might be useful in cancer therapy if it can be applied directly into tumors, and ''Lonchocarpus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insecticide
Insecticides are pesticides used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. The major use of insecticides is in agriculture, but they are also used in home and garden settings, industrial buildings, for vector control, and control of insect parasites of animals and humans. Acaricides, which kill mites and ticks, are not strictly insecticides, but are usually classified together with insecticides. Some insecticides (including common bug sprays) are effective against other non-insect arthropods as well, such as scorpions, spiders, etc. Insecticides are distinct from insect repellents, which repel but do not kill. Sales In 2016 insecticides were estimated to account for 18% of worldwide pesticide sales. Worldwide sales of insecticides in 2018 were estimated as $ 18.4 billion, of which 25% were neonicotinoids, 17% were pyrethroids, 13% were diamides, and the rest were many other classes which sold for less th ...

Spanish Conquest Of Yucatán
The Spanish conquest of Yucatán was the campaign undertaken by the Spanish Empire, Spanish ''conquistadores'' against the Mesoamerican chronology, Late Postclassic Maya civilization, Maya states and polities in the Yucatán Peninsula, a vast limestone plain covering south-eastern Mexico, northern Guatemala, and all of Belize. The Spanish colonization of the Americas, Spanish conquest of the Yucatán Peninsula was hindered by its politically fragmented state. The Spanish engaged in a strategy of concentrating native populations in newly founded colonial towns. Native resistance to the new nucleated settlements took the form of the flight into inaccessible regions such as the forest or joining neighbouring Maya peoples, Maya groups that had not yet submitted to the Spanish. Among the Maya, ambush was a favoured tactic. Spanish weaponry included broadswords, rapiers, lances, pike (weapon), pikes, halberds, crossbows, matchlocks, and light History of artillery, artillery.

Balché
''Balché'' is a mildly intoxicating beverage that was commonly consumed by the ancient Maya in what is now Mexico and upper Central America. Today, it is still common among the Maya. The drink is made from the bark of a leguminous tree, '' Lonchocarpus violaceus'', which is soaked in honey and water, and fermented. A closely related beverage, made from honey produced from the nectar of a species of morning glory Morning glory (also written as morning-glory) is the common name for over 1,000 species of flowering plants in the family Convolvulaceae, whose taxonomy and systematics remain in flux. These species are distributed across numerous genus, gene ... ''( Turbina corymbosa)'', is called '' xtabentún''. Ritual enemas and other psychoactive substances were also taken by those who drank balché. According to food writer Sandor Katz, the ancient Maya consumed ''balché'' in enema form to maximize its inebriating effect. After the Maya were conquered by the Spanish, the ...

Mead
Mead (), also called honey wine, and hydromel (particularly when low in alcohol content), is an alcoholic beverage made by fermenting honey mixed with water, and sometimes with added ingredients such as fruits, spices, grains, or hops. The alcoholic content ranges from about 3.5% ABV to more than 20%. Possibly the most ancient alcoholic drink, the defining characteristic of mead is that the majority of the beverage's fermentable sugar is derived from honey. It may be still, carbonated, or naturally sparkling, and despite a common misconception that mead is exclusively sweet, it can also be dry or semi-sweet. Mead that also contains spices is called (), and mead that contains fruit is called melomel. The term honey wine is sometimes used as a synonym for mead, although wine is typically defined to be the product of fermented grapes or certain other fruits, and some cultures have honey wines that are distinct from mead. The honey wine of Hungary, for example, is the fermentation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yukatek Maya
Yucatec Maya ( ; referred to by its speakers as or ) is a Mayan language spoken in the Yucatán Peninsula, including part of northern Belize. There is also a significant diasporic community of Yucatec Maya speakers in San Francisco, though most Maya Americans are speakers of other Mayan languages from Guatemala and Chiapas. Etymology According to the Hocabá dictionary, compiled by American anthropologist Victoria Bricker, there is a variant name , literally 'flat speech'). A popular, yet false, alternative etymology of Mayab is ''ma ya'ab'' or 'not many, the few', which derives from New Age spiritualist interpretations of the Maya. The use of "Mayab" as the name of the language seems to be unique to the town of Hocabá, as indicated by the Hocabá dictionary and is not employed elsewhere in the region or in Mexico, by either Spanish or Maya speakers. As used in Hocabá, "Mayab" is not the recognized name of the language, but instead a "nickname" derived from a common n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tumor
A neoplasm () is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia. The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persists in growing abnormally, even if the original trigger is removed. This abnormal growth usually forms a mass, which may be called a tumour or tumor.'' ICD-10 classifies neoplasms into four main groups: benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behavior. Malignant neoplasms are also simply known as cancers and are the focus of oncology. Prior to the abnormal growth of tissue, such as neoplasia, cells often undergo an abnormal pattern of growth, such as metaplasia or dysplasia. However, metaplasia or dysplasia does not always progress to neoplasia and can occur in other conditions as well. The word neoplasm is from Ancient Greek 'new' and 'formation, creation'.

Mammal
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews).

Parkinson's Disease
Parkinson's disease (PD), or simply Parkinson's, is a neurodegenerative disease primarily of the central nervous system, affecting both motor system, motor and non-motor systems. Symptoms typically develop gradually and non-motor issues become more prevalent as the disease progresses. The motor symptoms are collectively called parkinsonism and include tremors, bradykinesia, spasticity, rigidity as well as postural instability (i.e., difficulty maintaining balance). Non-motor symptoms develop later in the disease and include behavior change (individual), behavioral changes or mental disorder, neuropsychiatric problems such as sleep abnormalities, psychosis, anosmia, and mood swings. Most Parkinson's disease cases are idiopathic disease, idiopathic, though contributing factors have been identified. Pathophysiology involves progressive nerve cell death, degeneration of nerve cells in the substantia nigra, a midbrain region that provides dopamine to the basal ganglia, a system invo ...
