	Pineapple
		The plant is more compact, the fruit is smaller, more cylindrical; produces no slips but numerous suckers It may be the same as the 'Cayenne Lisse' strain grown in Martinique and on the Ivory Coast, the fruit of which weighs from 2 to 2 3/4 lbs (1-1 1/2 kg) and has a very small crown.
		Planting: In small plots or on very steep slopes, planting is done manually using the traditional short-handled narrow-bladed hoe, the handle of which, 12 in (30 cm) long, is used to measure the distance between plants.
		Plants treated with naphthaleneacetic acid produce long, cylindrical, pointed fruits, maturing over an extended period of time, ripening first at the base while the apex is still unripe.

	biology - Plant hormone
		Plant hormones (or plant growth regulators, or PGRs) are internally secreted chemicals in plants that are used for regulating their growth.
		The assumption of the theory is that plants are interested in growing larger during the vegetative period of their life and this growth requires both good environmental conditions and an amount of the four basic nutrient groups that exceeds that needed to keep the plant at its current size.
		The theory holds that the growth hormones are made when an excess of nutrients exists beyond that needed for survival, and thus a signal that growth can begin is warranted.

	Rejuvenation, My Personal Anti-Aging Program using Injectable Human Growth Hormone
		However, growth hormone is a powerful hormone and can have side effects so it must be taken only in the physiological doses that have been shown to be safe.
		Growth hormone reaches its highest level of secretion in the body of a 12 year old boy or girl, but by age 20 the amount of growth hormone secreted is down a full 75%.
		This increase in female hormone in a male body occurs normally with aging and is one of the reasons why men lose sex drive with age.

		Auxins are a group of plant growth substances (often called phytohormones or plant hormones), the most common example being indoleacetic acid (IAA), responsible for raising the pH around cells, making the cell wall less rigid and allowing elongation.
		The defoliant Agent Orange was a mix of 2, 4-D and 2, 4, 5-T. 2, 4-D is still in use and is thought to be safe, but 2, 4, 5-T was more or less banned by the EPA in 1979.

	Autism: An Overview and Theories on its Causes
		The opioid excess theory of autism says that autistic children are symptomatic due to excess opioid-like substances, whose effects on the brain produce the symptoms of autism.
		The pancreatic hormones, insulin and glucagon, are elevated by opioids apparently by an action at the islet cells.
		The viral theory of autism relies upon a relative immunosuppression, often thought to be in the intestinal tract, and a viral infection to produce the central nervous system symptoms of autism.

		I created the first article on plant hormones which since then has been smartly split off into plant hormone theory I, plant hormone theory II, auxin, cytokinin, gibberellin, Ethylene (plant hormone), abscisic acid, Salicylic acid (plant hormone), brassinosteroid, and polyamines.
		I also wrote the first article on plant senescence.

		Went came to the attention of workers in his field early with his dissertation studies on the plant growth hormone auxin.
		After his emigration to the United States in 1933 he became increasingly interested in the ecological and climatological interactions between plants and their environment.
		In 1949 he built the first phytotron, designed to facilitate controlled studies of the effect of climate on plant life; he was also involved in studies on atmospheric hydrocarbons and other kinds of matter found in the atmosphere, soil fungi, competition and evolution in desert plants, and air pollution (including the "blue haze" theory).

	History of Arthritis Research
		It was first proposed as a separate syndrome by Heberden and Haygarth in the early 19th century, Forming the backdrop of later research are several hypotheses, some borrowed from research into other diseases, and some with a novel twist of their own.
		Roughly his contention was that hormones released by the body, especially those released by the jacket of the adrenal glands, cause an adverse reaction to the joint tissues when they are released in too large amounts or the wrong ratios under conditions of environmental stress or psychic stress.
		The theory had some plausibility since arthritis can be produced by injecting deoxycorticosterone (DOC) into a person who has been suffering from Addisons's disease or into animals [Selye et al 1944][Turner].

		But that's not the case for tropical plants called spiral gingers, says Douglas Schemske, an evolutionary ecologist at Michigan State University in East Lansing.
		Schemske and his colleagues have found that more than 50 distinct spiral ginger species have evolved from a single common ancestor in just a few million years.
		The researchers are building a strong case that, for these species, rapid evolution occurred as slight genetic changes altered the plants' ability to attract various bee species and, more important, hummingbirds.
