Betel Nuts
The areca nut ( or ) or betel nut () is the fruit of the areca palm (''Areca catechu''). The palm is originally native to the Philippines, but was carried widely through the tropics by the Austronesian migrations and trade since at least 1500 BCE due to its use in betel nut chewing. It is widespread in cultivation and is considered naturalized in much of the tropical Pacific (Melanesia and Micronesia), South Asia, Southeast Asia, and parts of east Africa. It is not to be confused with betel (''Piper betle'') leaves that are often used to wrap it. The practice of betel nut chewing, often together with other herbs as a stimulant drug, dates back thousands of years, and continues to the present day in many countries. Betel nut chewing is addictive due to the presence of the stimulant arecoline, and causes adverse health effects, mainly oral and esophageal cancers, and cardiovascular disease. When chewed with additional tobacco in its preparation (like in gutka), there is an ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gutka
Gutka, ghutka, or guṭkha () is a type of betel quid and chewing tobacco preparation made of crushed areca nut (also called betel nut), tobacco, catechu, paraffin wax, slaked lime (calcium hydroxide) and sweet or savory flavourings, in India, Pakistan, other Asian countries, and North America. Using gutka is highly addictive and can cause various harmful effects such as head and neck cancer, oral and oropharyngeal cancers, coronary heart disease, as well as negative reproductive effects including stillbirth, premature birth and low birth weight. Gutka is manufactured in the sub-continent and exported to a few other countries, often marketed under the guise of a "safer" product than cigarettes and tobacco. Reported to have both stimulant and relaxation effects, it is sold throughout South Asia and some Pacific regions in small, individual-sized foil packets/sachets and tins that cost between 2 and 10 rupees each. It is widely consumed in India, Pakistan and the Madhesh reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
True Nut
A nut is a fruit consisting of a hard or tough nutshell protecting a kernel which is usually edible. In general usage and in a culinary sense, many dry seeds are called nuts, but in a botanical context, "nut" implies that the shell does not open to release the seed (indehiscent). Most seeds come from fruits that naturally free themselves from the shell, but this is not the case in nuts such as hazelnuts, chestnuts, and acorns, which have hard shell walls and originate from a compound ovary. Definition A seed is the mature fertilised ovule of a plant; it consists of three parts, the embryo which will develop into a new plant, stored food for the embryo, and a protective seed coat. Botanically, a nut is a fruit with a woody pericarp developing from a syncarpous gynoecium. Nuts may be contained in an involucre, a cup-shaped structure formed from the flower bracts. The involucre may be scaly, spiny, leafy or tubular, depending on the species of nut. Most nuts come from the pisti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

16th Century
The 16th century began with the Julian calendar, Julian year 1501 (represented by the Roman numerals MDI) and ended with either the Julian or the Gregorian calendar, Gregorian year 1600 (MDC), depending on the reckoning used (the Gregorian calendar introduced a lapse of 10 days in October 1582). The Renaissance in Italy and Europe saw the emergence of important artists, authors and scientists, and led to the foundation of important subjects which include accounting and political science. Copernicus proposed the Copernican heliocentrism, heliocentric universe, which was met with strong resistance, and Tycho Brahe refuted the theory of celestial spheres through observational measurement of the SN 1572, 1572 appearance of a Milky Way supernova. These events directly challenged the long-held notion of an immutable universe supported by Ptolemy and Aristotle, and led to major revolutions in astronomy and science. Galileo Galilei became a champion of the new sciences, invented the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Low Birth Weight
Low birth weight (LBW) is defined by the World Health Organization as a birth weight of an infant of or less, regardless of gestational age. Infants born with LBW have added health risks which require close management, often in a neonatal intensive care unit (NICU). They are also at increased risk for long-term health conditions which require follow-up over time. Classification Birth weight may be classified as: * High birth weight (macrosomia): greater than * Normal weight (term delivery): * Low birth weight: less than ** Very low birth weight (VLBW): less than ** Extremely low birth weight: less than Causes LBW is either caused by preterm birth (that is, a low gestational age at birth, commonly defined as younger than 37 weeks of gestation) or the infant being small for gestational age (that is, a slow prenatal growth rate), or a combination of both. In general, risk factors in the mother that may contribute to low birth weight include young ages, multiple pregnancie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extreme preterm is less than 28 weeks, very early preterm birth is between 28 and 32 weeks, early preterm birth occurs between 32 and 34 weeks, Late preterm infant, late preterm birth is between 34 and 36 weeks' gestation. These babies are also known as premature babies or colloquially preemies (American English) or premmies (Australian English). Symptoms of preterm labor include uterine contractions which occur more often than every ten minutes and/or the leaking of fluid from the vagina before 37 weeks. Premature infants are at greater risk for cerebral palsy, delays in development, hearing problems and problems with their Visual impairment, vision. The earlier a baby is born, the greater these risks will be. The cause of spontaneous preterm birth is often not known. R ...
