Alibertia Patinoi
''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 Panamá, 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 repres ...

José Cuatrecasas
José Cuatrecasas (1903–1996) was a Spanish botany, 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 Cuatrecasas Medal for Excellence in Tropical Botany, José Cuatrecasas Medal for Excellence in Tropical Botany annually. Honors *1950 List of Guggenheim Fellowships awarded in 1950, Guggenheim Fellowship Multiple plant species have been named for him, including ''Narcissus cuatrecasasii '', ''Joseanthus cuatrecasasii'', ''Pradosia cuatrecasasii'', and ''Tessmannianthu ...

Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) 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, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the Iron A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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), or 10,000 m2, 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 (10,000 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 (1,000 m2) 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, i ...

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. Antioxidant ...

Polyphenol
Polyphenols () are a large family of naturally occurring organic compounds characterized by multiples of phenol units. They are abundant in plants and structurally diverse. Polyphenols include flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning garments. Etymology The name derives from the Ancient Greek word (''polus'', meaning "many, much") and the word phenol which refers to a chemical structure formed by attaching to an aromatic benzenoid (phenyl) ring to a hydroxyl (-OH) group as is found in alcohols (hence the ''-ol'' suffix). The term polyphenol has been in use at least since 1894. Definition The term polyphenol is not well-defined, but is generally agreed that they are natural products "having a polyphenol structure (i.e., several hydroxyl groups on aromatic rings)" including four principal classes: "phenolic acids, flavonoids, stilbenes, and lignans". *Flavonoids include flavones, flavonols, flavanols, f ...

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 not receiving the correct amount of nutrition. Malnutrition is increasing in children under the age of five due to providers who cannot afford or do not have access to adequate nutrition. 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 underweight. A surplus of nutrients causes overnutrition, which can result in obesity. 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 'undernutrit ...

Hypertension
Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term medical condition in which the blood pressure in the arteries is persistently elevated. High blood pressure usually does not cause symptoms. Long-term high blood pressure, however, is 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 primary (essential) hypertension or secondary hypertension. About 90–95% of cases are primary, defined as high blood pressure due to nonspecific lifestyle and genetic factors. Lifestyle factors that increase the risk include excess salt in the diet, excess body weight, smoking, and alcohol use. The remaining 5–10% of cases are categorized as secondary high blood pressure, defined as high blood pressure due to an identifiable cause, such ...

Aphrodisiac
An aphrodisiac is a substance that increases sexual desire, sexual attraction, sexual pleasure, or sexual behavior. Substances range from a variety of plants, spices, foods, and synthetic chemicals. Natural aphrodisiacs like cannabis or cocaine are classified into plant-based and non-plant-based substances. There are non-naturally-occurring aphrodisiacs like MDMA and methamphetamine. Aphrodisiacs can be classified by their type of effects (i.e., psychological or physiological). Aphrodisiacs that contain hallucinogenic properties like Bufotenin have psychological effects on a person that can increase sexual desire and sexual pleasure. Aphrodisiacs that contain smooth muscle relaxing properties like yohimbine have physiological effects on a person that can affect hormone levels and increase blood flow. It is possible that the aphrodisiac effect of a substance is due to the placebo effect. Other substances that impede on areas that aphrodisiacs aim to enhance are classified as an ...
