Medals Of Honor (Japan)
are medals awarded by the Government of Japan. They are awarded to individuals who have done meritorious deeds and also to those who have achieved excellence in their field of work. The Medals of Honor were established on December 7, 1881, and were first awarded the following year. Several expansions and amendments have been made since then. The medal design for all six types are the same, bearing the stylized characters on a gilt central disc surrounded by a silver ring of cherry blossoms on the obverse; only the colors of the ribbon differ. If for some reason an individual were to receive a second medal of the same ribbon colour, then a second medal is not issued but rather a new bar is added to their current medal. The Medals of Honor are awarded twice each year, on April 29 (the birthday of the Shōwa Emperor) and November 3 (the birthday of the Meiji Emperor). Types Red ribbon First awarded in 1882. Awarded to individuals who have risked their own lives to save the live ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antihypertensive Drug
Antihypertensives are a class of drugs that are used to treat hypertension (high blood pressure). Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Evidence suggests that reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%, and can reduce the likelihood of dementia, heart failure, and mortality from cardiovascular disease. There are many classes of antihypertensives, which lower blood pressure by different means. Among the most important and most widely used medications are thiazide diuretics, calcium channel blockers, ACE inhibitors, angiotensin II receptor antagonists (ARBs), and beta blockers. Which type of medication to use initially for hypertension has been the subject of several large studies and resulting national guidelines. The fundamental goal of treatment should be the prevention of the important endpoints of hypertension, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercetin
Quercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, seeds, and grains; capers, red onions, and kale are common foods containing appreciable amounts of it. It has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods. Occurrence Quercetin is a flavonoid widely distributed in nature. The name has been used since 1857, and is derived from ''quercetum'' (oak forest), after the oak genus ''Quercus''. It is a naturally occurring polar auxin transport inhibitor. Quercetin is one of the most abundant dietary flavonoids, with an average daily consumption of 25–50 milligrams. In red onions, higher concentrations of quercetin occur in the outermost rings and in the part closest to the root, the latter being the part of the plant with the highest concentration. One study found that organically grown tomatoes had 79% more quercetin than non-organically grown fruit. Quercetin is presen ...

Sea Urchin
Sea urchins () are spiny, globular echinoderms in the class Echinoidea. About 950 species of sea urchin live on the seabed of every ocean and inhabit every depth zone from the intertidal seashore down to . The spherical, hard shells (tests) of sea urchins are round and spiny, ranging in diameter from . Sea urchins move slowly, crawling with tube feet, and also propel themselves with their spines. Although algae are the primary diet, sea urchins also eat slow-moving (sessile) animals. Predators that eat sea urchins include a wide variety of fish, starfish, crabs, marine mammals. Sea urchins are also used as food especially in Japan. Adult sea urchins have fivefold symmetry, but their pluteus larvae feature bilateral (mirror) symmetry, indicating that the sea urchin belongs to the Bilateria group of animal phyla, which also comprises the chordates and the arthropods, the annelids and the molluscs, and are found in every ocean and in every climate, from the tropics to the pol ...

Perilla Frutescens Var
''Perilla'' is a genus consisting of one major Asiatic crop species ''Perilla frutescens'' and a few wild species in nature belonging to the mint family, Lamiaceae. The genus encompasses several distinct varieties of Asian herb, seed, and vegetable crop, including '' P. frutescens'' (deulkkae) and ''P. frutescens'' var. ''crispa'' (shiso). The genus name ''Perilla'' is also a frequently employed common name ("perilla"), applicable to all varieties. Perilla varieties are cross-fertile and intra-specific hybridization occurs naturally. Some varieties are considered invasive. Taxa and synonyms The classification of ''Perilla'' is confused, partly because botanists struggled with distinguishing the two distinct cultigens as different species or variations. Until a few decades ago, ''P. frutescens'' var. ''crispa'' was regarded as a species in its own right, distinct from ''P. frutescens'', although it was well established that these types readily cross-pollinate. An early exam ...

Soybean
The soybean, soy bean, or soya bean (''Glycine max'') is a species of legume native to East Asia, widely grown for its edible bean, which has numerous uses. Traditional unfermented food uses of soybeans include soy milk, from which tofu and tofu skin are made. Fermented soy foods include soy sauce, fermented bean paste, nattō, and tempeh. Fat-free (defatted) soybean meal is a significant and cheap source of protein for animal feeds and many packaged meals. For example, soybean products, such as textured vegetable protein (TVP), are ingredients in many meat and dairy substitutes. Soybeans contain significant amounts of phytic acid, dietary minerals and B vitamins. Soy vegetable oil, used in food and industrial applications, is another product of processing the soybean crop. Soybean is the most important protein source for feed farm animals (that in turn yields animal protein for human consumption). Etymology The word "soy" originated as a corruption of the Cantonese or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eggplant
Eggplant ( US, Canada), aubergine ( UK, Ireland) or brinjal (Indian subcontinent, Singapore, Malaysia, South Africa) is a plant species in the nightshade family Solanaceae. ''Solanum melongena'' is grown worldwide for its edible fruit. Most commonly purple, the spongy, absorbent fruit is used in several cuisines. Typically used as a vegetable in cooking, it is a berry by botanical definition. As a member of the genus ''Solanum'', it is related to the tomato, chili pepper, and potato, although those are of the New World while the eggplant is of the Old World. Like the tomato, its skin and seeds can be eaten, but, like the potato, it is usually eaten cooked. Eggplant is nutritionally low in macronutrient and micronutrient content, but the capability of the fruit to absorb oils and flavors into its flesh through cooking expands its use in the culinary arts. It was originally domesticated from the wild nightshade species ''thorn'' or ''bitter apple'', '' S. incanum'',Tsao ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commelina Communis
''Commelina communis'', commonly known as the Asiatic dayflower, is an herbaceous annual plant in the dayflower family. It gets its name because the blooms last for only one day. It is native throughout much of East Asia and northern parts of Southeast Asia. In China, the plant is known as ''yazhicao'' (), roughly translating to "duckfoot herb", while in Japan it is known as , meaning "dew herb". It has also been introduced to parts of central and southeastern Europe and much of eastern North America, where it has spread to become a noxious weed. It is common in disturbed sites and in moist soil. The flowers emerge from summer through fall and are distinctive with two relatively large blue petals and one very small white petal. The Asiatic dayflower plant serves as the type species for its large genus. Linnaeus picked the name ''Commelina'' in honour of the two Dutch botanists of the Commelijn family, using the two large showy petals of ''Commelina communis'' to symbolise them ...
