Borojó
''Alibertia patinoi'', commonly known as , is a small (2-5m), dioecious tropical rainforest tree, one of the few edible fruit bearing species in the Rubiaceae family. Borojó, native to the world's wettest lowlands (the Chocó–Darién moist forests ecoregion), grows in the Chocó Department of northwestern Colombia and in the Esmeraldas Province of northwestern Ecuador. Borojó is an Emberá word meaning: ''boro'' = head, ''jo'' = fruit - head-shaped fruit, or round, globulous fruit. The species has also been reported from Panama, Venezuela and Costa Rica. Growth ''Alibertia patinoi'' has grey-brown bark and sometimes has two or three smaller trunks as well as one main one. It needs high humidity (over 85%) and temperature (an average of at least 25 °C) to thrive, though it can tolerate brief frosts as well as floods. Fruit The fruit is large (about 12 cm in length), with a round shape and brown color and average weight of 740-1000 grams. The pulp represent ...

José Cuatrecasas
José Cuatrecasas (1903–1996) was a Spanish botanist. He was born on March 19, 1903, in Camprodon, Catalonia, Spain. His research focused on the high-elevation páramo and sub-páramo regions of the Andes Mountains in South America, especially the flowering plant families Asteraceae and Malpighiaceae. He played an important role in the founding of the Organization for Flora Neotropica. In 1997, the Smithsonian Institution established the José Cuatrecasas Botanical Fund to "support significant research projects that emulate the spirit of the research of José Cuatrecasas". The Smithsonian also awards a José Cuatrecasas Medal for Excellence in Tropical Botany annually. Honors *1950 Guggenheim Fellowship Multiple plant species have been named for him, including ''Narcissus cuatrecasasii '', ''Joseanthus cuatrecasasii'', ''Pradosia cuatrecasasii'', and '' Tessmannianthus quadridomius'' (where "quadridomius" is Latin Latin ( or ) is a classical language belonging to t ...

Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Duroia Maguirei
''Duroia'' is a genus of flowering plants in the family Rubiaceae. The genus is found from Costa Rica to tropical South America. Ecology A number of ''Duroia'' species, and possibly all, are capable of biochemical interactions inhibiting the growth of neighbouring plants. Analysis of root extracts from ''Duroia hirsuta'' have yielded a strong plant growth inhibitor plumericin, a tetracyclic iridoid lactone. This process, common amongst plants, is termed allelopathy. In the case of ''Duroia hirsuta'', the chemical inhibitor is aided by the leafcutter ant ''Myrmelachista schumanni'' resident on and in the tree, and playing an active role in suppressing and destroying plant growth in the vicinity of their host by injecting and spraying formic acid. The area around the understory species ''Duroia hirsuta'' is often devoid of all other plant types, leading to the local name 'Devil's garden'. The cost to the host plant for this protection is considerable, since the resident ants subjec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

Oxygen Radical Absorbance Capacity
Oxygen radical absorbance capacity (ORAC) was a method of measuring antioxidant capacities in biological samples ''in vitro''. Because no physiological proof ''in vivo'' existed in support of the free-radical theory or that ORAC provided information relevant to biological antioxidant potential, it was withdrawn in 2012. Various foods were tested using this method, with certain spices, berries and legumes rated highly in extensive tables once published by the United States Department of Agriculture (USDA). Alternative measurements include the Folin-Ciocalteu reagent, and the Trolox equivalent antioxidant capacity assay. Method The assay measures the oxidative degradation of the fluorescent molecule (either beta-phycoerythrin or fluorescein) after being mixed with free radical generators such as azo-initiator compounds. Azo-initiators are considered to produce the peroxyl radical by heating, which damages the fluorescent molecule, resulting in the loss of fluorescence. Antioxi ...

Polyphenol
Polyphenols () are a large family of naturally occurring phenols. They are abundant in plants and structurally diverse. Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning (leather), tanning garments. Etymology The name derives from the Ancient Greek word (, meaning "many, much") and the word ‘phenol’ which refers to a chemical structure formed by attachment of an aromatic benzenoid (phenyl) ring to a hydroxyl (-OH) group (hence the ''-ol'' suffix). The term "polyphenol" has been in use at least since 1894. Definition Polyphenols are natural products with "one or several hydroxyl groups on aromatic rings", including four principal classes: phenolic acids, flavonoids, stilbenes, and lignans. Flavonoids can be grouped as flavones, flavonols, flavanols, flavanones, isoflavones, proanthocyanidins, and anthocyanins. Particularly abundant flavanoids in foods are catechin (tea, frui ...

Malnutrition
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form. Malnutrition is a category of diseases that includes undernutrition and overnutrition. Undernutrition is a lack of nutrients, which can result in stunted growth, wasting, and being underweight. A surplus of nutrients causes overnutrition, which can result in obesity or toxic levels of micronutrients. In some developing countries, overnutrition in the form of obesity is beginning to appear within the same communities as undernutrition. Most clinical studies use the term 'malnutrition' to refer to undernutrition. However, the use of 'malnutrition' instead of 'undernutrition' makes it impossible to distinguish between undernutrition and overnutrition, a less acknowledged form of malnutrition. Accordingly, a 2019 report by The Lance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypertension
Hypertension, also known as high blood pressure, is a Chronic condition, long-term Disease, medical condition in which the blood pressure in the artery, arteries is persistently elevated. High blood pressure usually does not cause symptoms itself. It is, however, a major risk factor for stroke, coronary artery disease, heart failure, atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia. Hypertension is a major cause of premature death worldwide. High blood pressure is classified as essential hypertension, primary (essential) hypertension or secondary hypertension. About 90–95% of cases are primary, defined as high blood pressure due to non-specific lifestyle and Genetics, genetic factors. Lifestyle factors that increase the risk include excess salt in the diet, overweight, excess body weight, smoking, physical inactivity and Alcohol (drug), alcohol use. The remaining 5–10% of cases are categorized as secondary hypertension, d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphrodisiac
An aphrodisiac is a substance that increases libido, sexual desire, sexual attraction, sexual pleasure, or sexual behavior. These substances range from a variety of plants, spices, and foods to synthetic chemicals. Natural aphrodisiacs, such as cannabis (drug), cannabis or cocaine, are classified into plant-based and non-plant-based substances. Synthetic aphrodisiacs include MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects (psychological or physiological). Aphrodisiacs that contain hallucinogenic properties, such as bufotenin, have psychological effects that can increase sexual desire and sexual pleasure. Aphrodisiacs that have smooth muscle relaxing properties, such as yohimbine, have physiological effects that can affect hormone concentrations and increase blood flow. Substances that have the opposite effects on libido are called anaphrodisiacs. Aphrodisiac effects can also be due to the Placebo, placebo effect. Both males and females can po ...
