What does endorheic mean?
Endorheic basin
An endorheic basin (also endoreic basin or endorreic basin) (from the , "éndon", "within" and , "rheîn", "to flow") is a limited drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. Such a basin may also be referred to as a closed or terminal basin or as an internal drainage system or interior drainage basin.
Oneiroid syndrome
Oneiroid syndrome (OS) is a condition involving dream-like disturbances of one's consciousness by vivid scenic hallucinations, accompanied by catatonic symptoms (either catatonic stupor or excitement), delusions, or psychopathological experiences of a kaleidoscopic nature. The term is from Ancient Greek "ὄνειρος" ("óneiros", meaning "dream") and "εἶδος" ("eîdos", meaning "form, likeness"; literally "dream-like" / "oneiric or oniric", sometimes called "nightmare-like"). It is a common complication of catatonic schizophrenia, although it can also be caused by other mental disorders. The dream-like experiences are vivid enough to seem real to the patient. OS is distinguished from delirium by the fact that the imaginative experiences of patients always have an internal projection. This syndrome is hardly mentioned in standard psychiatric textbooks because it comes from a phenomenological approach, in contrast to the American attitude, which deals with detailed clinical descriptions.
Thoracic endometriosis
Current theories describe the causes of extra-uterine endometriosis state that intra-abdominal and pelvic endometriosis is due to retrograde menstruation. This is thought to happen when menstrual debris may travel up through the fallopian tubes instead of out the cervix and vagina. When this occurs, endometrial tissue can attach to structures in the peritoneum. This does not, however, explain the rare cases in which endometrial tissue is deposited or develops above the diaphragm. Theories explaining distant ectopic endometriosis include:
A review of autopsy data showed that patients with endometriosis have bilateral pulmonary lesions, which supports the vascular embolisation theory. The pleural and/or diaphragmatic lesions were always found on the left side, which supports the theory of coelomic metaplasia.
Endostyle
The endostyle is an organ which assists lower-chordates (urochordates and cephalochordates, as well as the larvae of lampreys) in filter-feeding. This pharyngeal organ secretes mucus which utilizes cilia to coat itself. The mucus produced by the endostyle adheres to food particles that are in the water and this mixture is then passed through the pharynx of the organism and into the esophagus through the sweeping movement of the cilia. The endostyle in larval lampreys (ammocoetes) metamorphoses into the thyroid gland in adults, and is regarded as being homologous to the thyroid gland in vertebrates due to its iodine-concentrating activity. Since the endostyle is found in the three branches of chordates, it is presumed to have arisen in the common ancestor of these taxa, along with a shift to internal feeding for extracting suspended food from the water.
Perlecan
Hypoxia is a condition found in disease states and during injury and often results in a lack of endothelial cell proliferation. This and perlecan's role as endorepellin prompted one study into the nature of perlecan expression regulation by endothelial cells during hypoxic conditions. Under hypoxic conditions, this study found that perlecan expression by rat cardiac microvascular endothelial cells was decreased sixty-one percent compared to normal controls. The contention of this paper is that perlecan downregulation leads to a loss of FAK activation and thus less ERK signaling, leading to decreased cell proliferation. It does seem counterintuitive that endothelial cells would proliferate less quickly due to loss of perlecan and its endorepellin subunit. It could be that these endothelial cells merely downregulated transcription of many genes in response to hypoxic conditions. In another study, hypoxia led to induction of genes associated with apoptosis and cell death, but repression of genes was not limited to proteins associated with a specific pathway. When T84 intestinal epithelial cells are exposed to hypoxic conditions for 24 hours a significant increase in perlecan mRNA and protein production occurs. They relate this to the fact that many genes elevated in response to hypoxia contain a cAMP response element (CRE) in their promoter, as does pln. This difference between endothelial cells from the study in 2007 and the epithelial cell studied in these experiments is indicative of how varied the regulatory mechanisms of perlecan may be in different cell types.
Endoneurium
The endoneurium (also called endoneurial channel, endoneurial sheath, endoneurial tube, or Henle's sheath) a layer of delicate connective tissue around the myelin sheath of each myelinated nerve fiber. Its component cells are called endoneurial cells. The endoneuria with their enclosed nerve fibers are bundled into groups called nerve fascicles, each fascicle within its own protective sheath called a perineurium. In sufficiently large nerves multiple fascicles, each with its blood supply and fatty tissue, may be bundled within yet another sheath, the epineurium.
Psychedelia
The impact of psychedelic drugs on western culture in the 1960s led to semantic drift in the use of the word "psychedelic", and it is now frequently used to describe anything with abstract decoration of multiple bright colours, similar to those seen in drug-induced hallucinations. In objection to this new meaning, and to what some consider pejorative meanings of other synonyms such as "hallucinogen" and "psychotomimetic", the term "entheogen" was proposed and is seeing increasing use. However, many consider the term "entheogen" best reserved for religious and spiritual usage, such as certain Native American churches do with the peyote sacrament, and "psychedelic" left to describe those who are using these drugs for recreation, psychotherapy, physical healing, or creative problem solving. In science, hallucinogen remains the standard term.
Ephemerality
Any endorheic basin, or closed basin, that contains a playa or dry lake at its drainage lowpoint can become an ephemeral lake. Examples include Lake Carnegie in Western Australia, Lake Cowal in New South Wales, Mystic Lake and Rogers Lake in California, and Sevier Lake in Utah. Even the driest and lowest place in North America, Death Valley (more specifically Badwater Basin), became flooded with a short-lived ephemeral lake in the spring of 2005.
Endomorphic
Endomorphic can refer to:
Euphoria
In 1940 "The Journal of Psychology" defined euphoria as a "state of general well being ... and pleasantly toned feeling." A decade later, finding "ordinary feelings of well being" difficult to evaluate, American addiction researcher Harris Isbell redefined euphoria as behavioral changes and objective signs typical of morphine. However, in 1957 British pharmacologist D. A. Cahal did not regard opioid euphoria as medically undesirable but an effect which "enhance[s] the value of a major analgesic." The 1977 edition of "A Concise Encyclopaedia of Psychiatry" called euphoria "a mood of contentment and well-being," with pathologic associations when used in a psychiatric context. As a sign of cerebral disease, it was described as bland and out of context, representing an inability to experience negative emotion.
Endorphins
From the words / meaning "within" (endogenous, / , "proceeding from within") and morphine, from Morpheus (), the god of dreams in the Greek mythology, thus 'endo(genous) (mo)rphine’.
Enterotoxigenic Escherichia coli
Enterotoxigenic "Escherichia coli" (ETEC) is a type of "Escherichia coli" and one of the leading bacterial causes of diarrhea in the developing world, as well as the most common cause of travelers' diarrhea. Insufficient data exist, but conservative estimates suggest that each year, about 157,000 deaths occur, mostly in children, from ETEC. A number of pathogenic isolates are termed ETEC, but the main hallmarks of this type of bacteria are expression of one or more enterotoxins and presence of fimbriae used for attachment to host intestinal cells.
Endorheic basin
Even within exorheic basins, there can be "non-contributing", low-lying areas that trap runoff and prevent it from contributing to flows downstream during years of average or below-average runoff. In flat river basins, non-contributing areas can be a large fraction of the river basin, e.g. Lake Winnipeg's basin. A lake may be endorheic during dry years and can overflow its basin during wet years, e.g., the former Tulare Lake.
Night hag
The original definition of sleep paralysis was codified by Samuel Johnson in his "A Dictionary of the English Language" as "nightmare", a term that evolved into our modern definition. Such sleep paralysis was widely considered the work of demons, and more specifically incubi, which were thought to sit on the chests of sleepers. In Old English the name for these beings was "mare" or "mære" (from a proto-Germanic "*marōn", cf. Old Norse "mara"), hence comes the "mare" part in "nightmare". The word might be etymologically cognate to Greek "Marōn" (in the Odyssey) and Sanskrit "Māra".
Idiopathic disease
The word essential is sometimes synonymous with "idiopathic" (as in essential hypertension, essential thrombocythemia, and essential tremor) and the same is true of primary (as in primary biliary cholangitis, or "primary amenorrhea"), with the latter term being used in such cases to contrast with "secondary" in the sense of "secondary to [i.e., caused by] some other condition." Another, less common synonym is agnogenic ("agno-", "unknown" + "-gen", "cause" + "-ic"). The word "cryptogenic" ("crypto-", "hidden" + "-gen", "cause" + "-ic") has a sense that is synonymous with "idiopathic" and a sense that is contradistinguished from it.
Paregoric
However, Paregoric was characterized as "a needlessly complex pharmacopeial mixture... of a former day" by a 1966 study. In the 21st century its two main uses have been largely supplanted by minimally psychoactive cough-suppressant drugs (such as dextromethorphan) and non-psychoactive antidiarrheal drugs (such as loperamide).
Lake
Most lakes have at least one natural outflow in the form of a river or stream, which maintain a lake's average level by allowing the drainage of excess water. Some lakes do not have a natural outflow and lose water solely by evaporation or underground seepage or both. They are termed endorheic lakes.
Castlereagh River
The Castlereagh’s alluvial sandbeds make up what is called the "hyperheic zone". This is the region of saturated sediment below, or adjacent to, a river where surface water and groundwater are actively mixing and exchanged. The movement of the groundwater in the Castlereagh through its alluvial sands is said to be a hyporheic process. In the Castlereagh, the further transit of surface water to the aquifers of the Great Artesian Basin is then enabled through the ancient paleochannels underlying the Castlereagh, and this water movement is a large-scale hyporheic process. (Hutchinson and Webster 1998).
Benthic zone
For comparison, the pelagic zone is the descriptive term for the ecological region above the benthos, including the water-column up to the surface. Depending on the water-body, the benthic zone may include areas that are only a few inches below water, such as a stream or shallow pond; at the other end of the spectrum, benthos of the deep ocean includes the bottom levels of the oceanic abyssal zone.
Chronic fatigue syndrome
From 1934 onwards, outbreaks of a previously unknown illness began to be recorded by doctors. Initially considered to be occurrences of poliomyelitis, the illness was subsequently referred to as "epidemic neuromyasthenia". In the 1950s, the term "benign myalgic encephalomyelitis" was used in relation to a comparable outbreak at the Royal Free Hospital in London. The descriptions of each outbreak were varied, but included symptoms of malaise, tender lymph nodes, sore throat, pain, and signs of encephalomyelitis. The cause of the condition was not identified, although it appeared to be infectious, and the term "benign myalgic encephalomyelitis" was chosen to reflect the lack of mortality, the severe muscular pains, symptoms suggesting damage to the nervous system, and to the presumed inflammatory nature of the disorder. However, critics point out that the illness is rarely benign, doesn't always cause muscle pain, and is possibly never encephalomyelitic. The syndrome appeared in sporadic as well as epidemic cases and in 1969, benign myalgic encephalomyelitis appeared as an entry to the International Classification of Diseases under Diseases of the nervous system.
Endometriosis
Thoracic endometriosis is associated with recurrent pneumothoraces at times of a menstrual period, termed catamenial pneumothorax.
Endorheic basin
Endorheic regions can occur in any climate but are most commonly found in desert locations. In areas where rainfall is higher, riparian erosion will generally carve drainage channels (particularly in times of flood), or cause the water level in the terminal lake to rise until it finds an outlet, breaking the enclosed endorheic hydrological system's geographical barrier and opening it to the surrounding terrain. The Black Sea was likely such a lake, having once been an independent hydrological system before the Mediterranean Sea broke through the terrain separating the two. Lake Bonneville was another such lake, overflowing its basin in the Bonneville flood. The Malheur/Harney lake system in Oregon is normally cut off from drainage to the ocean, but has an outflow channel to the Malheur River that is normally dry, but flows in years of peak precipitation.
Ennead
Ennead is a borrowing via Latin of the Greek name "Enneás" (), meaning "the Nine". The term was a calque of the Egyptian name, written "" and also meaning "the Nine". Its original pronunciation is uncertain, since hieroglyphs do not record vowels. Egyptologists conventionally transcribe it as "Pesedjet".
Entropezites
The generic epithet "Entropezites" is Greek in derivation and is a combination of the words "entrope" meaning "to turn inward" and "ites" which means "pertaining to" referencing the hypermycoparasitic nature of the species.
Entheogenic (band)
Entheogenic was formed in 1999 by producer, engineer, and songwriter Piers Oak-Rhind and Helmut Glavar. The duo met while working for Emagic (a former producer of music-studio software and hardware such as Logic, acquired by Apple Inc. in 2002). The name "Entheogenic" is derived from the term "Entheogen" coined in 1979 by a group of ethnobotanists and mythology scholars to describe psychedelic substances used in a religious or shamanic context.
Hyporheic zone
The term hyporheic was originally coined by Traian Orghidan in 1959 by combining two Greek words: "hypo" (below) and "rheos" (flow).
Corneal dystrophy
Endothelial dystrophies
Horse colic
Clostridial enterocolitis due to infection by "Clostridium perfringens" is most commonly seen in foals under 3 months of age. Clostridial toxins damage the intestine, leading to dehydration and toxemia. Foals usually present with signs of colic, decreased nursing, abdominal distention, and diarrhea which may contain blood. Diagnosis is made with fecal culture, and while some foals do not require serious intervention, others need IV fluids, antibiotics, and aggressive treatment, and may still die. Other bacterial infections that may lead to enterocolitis include "Salmonella", "Klebsiella", "Rhodococcus equi", and "Bacteriodes fragilis".
Encopresis
Encopresis (from the Ancient Greek ἐγκόπρησις / egkóprēsis), also known as paradoxical diarrhea, is voluntary or involuntary passage of feces outside of toilet trained contexts (fecal soiling) in children who are four years or older and after an organic cause has been excluded. Children with encopresis often leak stool into their undergarments.
Shigatoxigenic and verotoxigenic Escherichia coli
Shigatoxigenic "Escherichia coli (STEC) and verotoxigenic "E. coli (VTEC) are strains of the bacterium "Escherichia coli" that produce either Shiga toxin or Shiga-like toxin (verotoxin). Only a minority of the strains cause illness in humans. The ones that do are collectively known as enterohemorrhagic "E. coli" (EHEC) and are major causes of foodborne illness. When infecting humans, they often cause gastroenteritis, enterocolitis, and bloody diarrhea (hence the name "enterohemorrhagic") and sometimes cause a severe complication called hemolytic-uremic syndrome (HUS). The group and its subgroups are known by various names. They are distinguished from other pathotypes of intestinal pathogenic "E. coli" including enterotoxigenic "E. coli" (ETEC), enteropathogenic "E. coli" (EPEC), enteroinvasive "E. coli" (EIEC), enteroaggregative "E. coli" (EAEC), and diffusely adherent "E. coli" (DAEC).
Anorectic
The term is (from the Greek "ἀν-" (an-) = "without" and "ὄρεξις" (órexis) = "appetite"), and such drugs are also known as anorexigenic, anorexiant, or appetite suppressant.
Biogeographic realm
The drainage basins of the principal oceans and seas of the world are marked by continental divides. The grey areas are endorheic basins that do not drain to the ocean.
Baraboo Range
Devil's Lake, the centerpiece of Devil's Lake State Park, was formed from terminal moraines blocking access to its outlet, creating what is today an endorheic lake (i.e., a lake lacking a surface outlet to the world's oceans).
Drainage basin
Endorheic drainage basins are inland basins that do not drain to an ocean. Around 18% of all land drains to endorheic lakes or seas or sinks. The largest of these consists of much of the interior of Asia, which drains into the Caspian Sea, the Aral Sea, and numerous smaller lakes. Other endorheic regions include the Great Basin in the United States, much of the Sahara Desert, the drainage basin of the Okavango River (Kalahari Basin), highlands near the African Great Lakes, the interiors of Australia and the Arabian Peninsula, and parts in Mexico and the Andes. Some of these, such as the Great Basin, are not single drainage basins but collections of separate, adjacent closed basins.
Dydrogesterone
Endometriosis is a chronic disease which can cause severe, progressive, and at times, incapacitating dysmenorrhea, pelvic pain, dyspareunia and infertility. Dydrogesterone relieves pain without inhibiting ovulation, so that patients are able to become pregnant during treatment. Dydrogesterone is particularly suitable in cases where the woman desires to become pregnant and to prevent bleeding problems. Dydrogesterone results in statistically significant reductions in the symptoms pelvic pain, dysmenorrhea and dyspareunia after the first treatment cycle for the treatment of post-laparoscopic endometriosis. The amount and duration of menstrual bleeding is also significantly reduced, and from the end of the third month onwards, bleeding was considered normal in the majority of patients. Improvement of endometriosis was observed in 71% of patients and cure in 21%.
Endorheic basin
Though a large portion of Europe drains to the endorheic Caspian Sea, Europe's wet climate means it contains relatively few terminal lakes itself: any such basin is likely to continue to fill until it reaches an overflow level connecting it with an outlet or erodes the barrier blocking its exit. Exceptions include:All these lakes are drained, however, either through manmade canals or via karstic phenomena. Minor endorheic lakes exist throughout the Mediterranean countries of Spain (e.g. Laguna de Gallocanta, Estany de Banyoles), Italy, Cyprus (Larnaca and Akrotiri salt lakes) and Greece.Some of the Earth's ancient endorheic systems and lakes include:
Ethylmalonic encephalopathy
Ethylmalonic encephalopathy (EE) is a rare autosomal recessive inborn error of metabolism. Patients affected with EE are typically identified shortly after birth, with symptoms including diarrhea, petechiae and seizures. The genetic defect in EE is thought to involve an impairment in the degradation of sulfide intermediates in the body. Hydrogen sulfide then builds up to toxic levels. EE was initially described in 1994. Most cases of EE have been described in individuals of Mediterranean or Arabic origin.
Human feces
Diarrhea (or diarrhoea in British English) is the condition of having three or more loose or liquid bowel movements per day. This condition can be a symptom of injury, disease or foodborne illness and is usually accompanied by abdominal pain. There are other conditions which involve some but not all of the symptoms of diarrhea, and so the formal medical definition of diarrhea involves defecation of more than 200 grams per day (though formal weighing of stools to determine a diagnosis is never actually carried out).
Hypertensive encephalopathy
Hypertensive encephalopathy (HE) is general brain dysfunction due to significantly high blood pressure. Symptoms may include headache, vomiting, trouble with balance, and confusion. Onset is generally sudden. Complications can include seizures, posterior reversible encephalopathy syndrome, and bleeding in the back of the eye.
In hypertensive encephalopathy, generally the blood pressure is greater than 200/130 mmHg. Occasionally it can occur at a BP as low as 160/100 mmHg. This can occur in kidney failure, those who rapidly stop blood pressure medication, pheochromocytoma, and people on a monoamine oxidase inhibitor (MAOI) who eats foods with tyramine. When it occurs in pregnancy it is known as eclampsia. The diagnosis requires ruling out other possible causes.
The condition is generally treated with medications to relatively rapidly lower the blood pressure. This may be done with labetalol or sodium nitroprusside given by injection into a vein. In those who are pregnant, magnesium sulfate may be used. Other treatments may include anti-seizure medications.
Hypertensive encephalopathy is uncommon. It is believed to occur more often in those without easy access to health care. The term was first used by Oppenheimer and Fishberg in 1928. It is classified as a type of hypertensive emergency.
Pyrrhonism
Pyrrhonism's objective is principally psychological, although it is best known for its epistemological arguments, particularly the problem of the criterion and the problem of induction. Through epoché (suspension of judgment) the mind is brought to ataraxia, a state of equanimity. As in Stoicism and Epicureanism, eudaimonia is the Pyrrhonist goal of life, and all three philosophies placed it in ataraxia or apatheia. According to the Pyrrhonists, it is one's opinions about non-evident matters that prevent one from attaining eudaimonia.
Horse colic
Endotoxemia is a serious complication of colic and warrants aggressive treatment. Endotoxin (lipopolysaccharide) is released from the cell wall of gram-negative bacteria when they die. Normally, endotoxin is prevented from entering systemic circulation by the barrier function of the intestinal mucosa, antibodies and enzymes which bind and neutralize it and, for the small amount that manages to enter the blood stream, removal by Kupffer cells in the liver. Endotoxemia occurs when there is an overgrowth and secondary die-off of gram negative bacteria, releasing mass quantities of endotoxin. This is especially common when the mucosal barrier is damaged, as with ischemia of the GI tract secondary to a strangulating lesion or displacement. Endotoxemia produces systemic effects such as cardiovascular shock, insulin resistance, and coagulation abnormalities.
Amenorrhea
The term is derived from Greek: "a" = negative, "men" = month, "rhoia" = flow. Derived adjectives are "amenorrhoeal" and "amenorrhoeic". The opposite is the normal menstrual period (eumenorrhoea).
List of endorheic basins
The following is a list of endorheic basins—watersheds which do not drain to the sea.
Some of the Earth's ancient endorheic systems include:
Endorheic basin
Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas.
Endorheic basin
Endorheic regions tend to be far inland with their boundaries defined by mountains or other geological features that block their access to oceans. Since the inflowing water can evacuate only through seepage or evaporation, dried minerals or other products collect in the basin, eventually making the water saline and also making the basin vulnerable to pollution. Continents vary in their concentration of endorheic regions due to conditions of geography and climate. Australia has the highest percentage of endorheic regions at 21 percent while North America has the least at 5 percent. Approximately 18 percent of the earth's land drains to endorheic lakes or seas, the largest of these land areas being the interior of Asia.
In deserts, water inflow is low and loss to solar evaporation high, drastically reducing the formation of complete drainage systems. Closed water flow areas often lead to the concentration of salts and other minerals in the basin. Minerals leached from the surrounding rocks are deposited in the basin, and left behind when the water evaporates. Thus endorheic basins often contain extensive salt pans (also called salt flats, salt lakes, alkali flats, dry lake beds or playas). These areas tend to be large, flat hardened surfaces and are sometimes used for aviation runways or land speed record attempts, because of their extensive areas of perfectly level terrain.
Chronic solvent-induced encephalopathy
Chronic solvent induced encephalopathy (CSE) is a condition induced by long-term exposure to organic solvents, often but not always in the workplace, that lead to a wide variety of persisting sensorimotor polyneuropathies and neurobehavioral deficits even after solvent exposure has been removed. This syndrome can also be referred to as "psycho-organic syndrome", "organic solvent syndrome", "chronic painter's syndrome", "occupational solvent encephalopathy", "solvent intoxication", "toxic solvent syndrome", "painters disease", "psycho-organic syndrome", "chronic toxic encephalopathy", and "neurasthenic syndrome". The multiple names of solvent induced syndromes combined with inconsistency in research methods makes referencing this disease difficult and its catalog of symptoms vague.
Epizootic
Common diseases that occur at a constant but relatively high rate in the population are said to be "enzootic" ("cf." the epidemiological meaning of "endemic" for human diseases). An example of an enzootic disease would be the influenza virus in some bird populations or, at a lower incidence, the Type IVb strain of VHS in certain Atlantic fish populations.
Dysmenorrhea
Dysmenorrhea, also known as painful periods, or menstrual cramps, is pain during menstruation. Its usual onset occurs around the time that menstruation begins. Symptoms typically last less than three days. The pain is usually in the pelvis or lower abdomen. Other symptoms may include back pain, diarrhea, or nausea.
In young women painful periods often occur without an underlying problem. In older women it is more often due to an underlying issues such as uterine fibroids, adenomyosis, or endometriosis. It is more common among those with heavy periods, irregular periods, whose periods started before twelve years of age, or who have a low body weight. A pelvic exam in those who are sexually active and ultrasound may be useful to help in diagnosis. Conditions that should be ruled out include ectopic pregnancy, pelvic inflammatory disease, interstitial cystitis, and chronic pelvic pain.
Dysmenorrhea occurs less often in those who exercise regularly and those who have children early in life. Treatment may include the use of a heating pad. Medications that may help include NSAIDs such as ibuprofen, hormonal birth control, and the IUD with progestogen. Taking vitamin B or magnesium may help. Evidence for yoga, acupuncture, and massage is insufficient. Surgery may be useful if certain underlying problems are present.
Estimates of the percentage of women of reproductive age affected varying from 20 to 90%. It is the most common menstrual disorder. Typically it starts within a year of the first menstrual period. When there is no underlying cause often the pain improves with age or following having a child.
The main symptom of dysmenorrhea is pain concentrated in the lower abdomen or pelvis. It is also commonly felt in the right or left side of the abdomen. It may radiate to the thighs and lower back.
Drainage basin
In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground.
Open and closed lakes
Open and closed lakes refer to the major subdivisions of lakes - bodies of water surrounded by land. Exorheic, or open lakes drain into a river, or other body of water that ultimately drains into the ocean. Endorheic basins fall into the category of endorheic or closed lakes, wherein waters do not drain into the ocean, but are reduced by evaporation, and/or drain into the ground.
Endorheic basin
Much of western and Central Asia is a giant endorheic region made up of a number of contiguous closed basins. The region contains several basins and terminal lakes, including:
Insomniac
Insomniac or The Insomniac may refer to:
Encephalitis
Certain parasitic or protozoal infestations, such as toxoplasmosis, malaria, or primary amoebic meningoencephalitis, can also cause encephalitis in people with compromised immune systems. Lyme disease or "Bartonella henselae" may also cause encephalitis.
Endometrium
If there is inadequate stimulation of the lining, due to lack of hormones, the endometrium remains thin and inactive. In humans, this will result in amenorrhea, or the absence of a menstrual period. After menopause, the lining is often described as being atrophic. In contrast, endometrium that is chronically exposed to estrogens, but not to progesterone, may become hyperplastic. Long-term use of oral contraceptives with highly potent progestins can also induce endometrial atrophy.
Lydia Pinkham
Of the newer additions, motherwort is a nervine, emmenagogue, anti-spasmodic, hepatic, cardiac tonic, and hypotensive. Piscidia erythrina (Jamaican dogwood) is an eclectic remedy effective for painful spasms, pelvic pain, dysmenorrhea, and ovarian pain. Licorice is anti-inflammatory, anti-hepatotoxic, anti-spasmodic, and a mild laxative. Gentian is a sialagogue, hepatic, cholagogue, anthelmintic, and emmenagogue. Dandelion is a potassium-sparing diuretic, hepatic, cholagogue, anti-rheumatic, laxative, tonic, and a bitter.
It is often suggested by the alternative medicine community that black cohosh (and a purified version, "Remifemin") really do provide relief from symptoms of menopause. A report by Natural Standard, which performs evidence-based reviews of alternative therapeutics, gives the evidence a "B" rating, "good scientific evidence for this use", saying:
Black cohosh is a popular alternative to prescription hormonal therapy for treatment of menopausal symptoms such as hot flashes, mood problems, perspiration, heart palpitations, and vaginal dryness. Initial human research suggests that black cohosh may improve some of these symptoms for up to six months. However, most studies are not well designed and results are not conclusive.
Endolymphatic hydrops
Endolymphatic hydrops may occur as a result of trauma such as a blow to the head, infection, degeneration of the inner ear, allergies, dehydration and loss of electrolytes or in extremely rare circumstances a benign tumor such as an endolymphatic sac tumor. In many cases, it is not clear what causes the disorder. Meniere’s attacks occur when there is an increase in endolymphatic volume in the inner ear, causing a temporary leak in the membrane separating the perilymph (potassium poor fluid) and the endolymph (potassium rich fluid). The mix of these two fluids surrounding the vestibular sensory cells can lead to a temporary electrical blockade and loss of sensory function. The sudden change in the rate of the vestibular nerve firing results in a disturbance of signal processing in the corresponding brain regions, and thus to acute sensations of imbalance, otherwise known as vertigo.
Eldorado Valley
The endorheic basin lies north of the "Piute Wash Watershed", of the north-south Piute Valley. The Piute Wash drains south, then southeast to the Colorado River.
Endorheic basin
Endorheic lakes are usually in the interior of a landmass, far from an ocean in areas of relatively low rainfall. Their watersheds are often confined by natural geologic land formations such as a mountain range, cutting off water egress to the ocean. The inland water flows into dry watersheds where the water evaporates, leaving a high concentration of minerals and other inflow erosion products. Over time this input of erosion products can cause the endorheic lake to become relatively saline (a "salt lake"). Since the main outflow pathways of these lakes are chiefly through evaporation and seepage, endorheic lakes are usually more sensitive to environmental pollutant inputs than water bodies that have access to oceans, as pollution can be trapped in them and accumulate over time.
Buada Lagoon
The lagoon is classified as an endorheic lake, meaning there is no outflow to other bodies of water such as oceans or rivers.
Cannabinoidergic
Cannabinoidergic, or cannabinergic, means "working on the endocannabinoid neurotransmitters". As with terms such as dopaminergic and serotonergic, related proteins and cellular components involved endocannabinoid signaling, such as the cannabinoid (CB) receptor, as well as exogenous compounds, such as phytocannabinoids or other cannabinoids which modulate the activity of endocannabinoid system, can be described as cannabinoidergic.
Endorphins
Endorphins (contracted to"endogenous morphine") are endogenous opioid neuropeptides and peptide hormones in humans and other animals. They are produced by the central nervous system and the pituitary gland. The term "endorphins" implies a pharmacological activity (analogous to the activity of the corticosteroid category of biochemicals) as opposed to a specific chemical formulation. It consists of two parts: "endo-" and "-orphin"; these are short forms of the words "endogenous" and "morphine," intended to mean "a morphine-like substance originating from within the body". The class of endorphins includes three compounds – α-endorphin - (Alpha endorphins), β-endorphin - (Beta endorphins), and γ-endorphin - (gamma endorphins)- which preferentially bind to μ-opioid receptors. The principal function of endorphins is to inhibit the communication of pain signals; they may also produce a feeling of euphoria very similar to that produced by other opioids.
Dysentery
Amoebiasis, also known as amoebic dysentery, is caused by an infection from the amoeba "Entamoeba histolytica", which is found mainly in tropical areas. Proper treatment of the underlying infection of amoebic dysentery is important; insufficiently treated amoebiasis can lie dormant for years and subsequently lead to severe, potentially fatal, complications.
Glycine encephalopathy
Glycine encephalopathy is sometimes referred to as "nonketotic hyperglycinemia" (NKH), as a reference to the biochemical findings seen in patients with the disorder, and to distinguish it from the disorders that cause "ketotic hyperglycinemia" (seen in propionic acidemia and several other inherited metabolic disorders). To avoid confusion, the term "glycine encephalopathy" is often used, as this term more accurately describes the clinical symptoms of the disorder.
Residual sodium carbonate index
The endorheic basin lakes are called soda or alkaline lakes when the water inflows contain high concentrations of NaCO. The pH of the soda lake water is generally above 9 and sometimes the salinity is close to brackish water due to depletion of pure water by solar evaporation.
Enaree
An Enaree or Enarei () was a Scythian shaman; described as effeminate or androgynous. Scythian shamanism involved religious ecstasy through the use of entheogens; they had no temples and worshipped the forces of nature.
Encephalopathy
Encephalopathy (; from "brain" + πάθος "suffering") means any disorder or disease of the brain, especially chronic degenerative conditions. In modern usage, encephalopathy does not refer to a single disease, but rather to a syndrome of overall brain dysfunction; this syndrome can have many different organic and inorganic causes.
Cruise ship
Enterotoxigenic "Escherichia coli" is a form of "E. coli" and the leading bacterial cause of diarrhea in the developing world, as well as the most common cause of diarrhea for travelers to those areas. Since 2008 there has been at least one reported incident each year of "E. coli" on international cruise ships reported to the Vessel Sanitation Program of the Centers for Disease Control, though there were none in 2015. Causes of "E. coli" infection include the consumption of contaminated food and the ingestion of water in swimming pools contaminated by human waste.
Narcotic
The term narcotic (, from ancient Greek ναρκῶ "narkō", "to make numb") originally referred medically to any psychoactive compound with sleep-inducing properties. In the United States, it has since become associated with opiates and opioids, commonly morphine and heroin, as well as derivatives of many of the compounds found within raw opium latex. The primary three are morphine, codeine, and thebaine (while thebaine itself is only very mildly psychoactive, it is a crucial precursor in the vast majority of semi-synthetic opioids, such as oxycodone).

Entorhinal cortex
The entorhinal cortex (EC) (ento = interior, rhino = nose, entorhinal = interior to the rhinal sulcus) is an area of the brain located in the medial temporal lobe and functioning as a hub in a widespread network for memory, navigation and the perception of time. The EC is the main interface between the hippocampus and neocortex. The EC-hippocampus system plays an important role in declarative (autobiographical/episodic/semantic) memories and in particular spatial memories including memory formation, memory consolidation, and memory optimization in sleep. The EC is also responsible for the pre-processing (familiarity) of the input signals in the reflex nictitating membrane response of classical trace conditioning, the association of impulses from the eye and the ear occurs in the entorhinal cortex.
Lonomia obliqua
Disseminated intravascular coagulation occurs as the toxin interacts with the victim's body. One serious effect on envenomed victims is hemorrhage syndrome. "First described by Arocha-Pinango and Layrisse in Venezuela in 1967, the hemorrhagic diathesis caused in humans by touching the "Lonomia" species begins with inflammatory changes at the site of envenoming, followed by systemic symptoms such as headache, fever, vomiting, and malaise. After 24 hours, a severe bleeding disorder ensues, leading to ecchymosis, hematuria, pulmonary, and intracranial hemorrhages, and acute renal failure."
Endorheic basin
Endorheic lakes in Antarctica are located in the McMurdo Dry Valleys, Victoria Land, the largest ice-free area in Antarctica.
Epidemic
The term epidemic derives from a word form attributed to Homer's "Odyssey", which later took its medical meaning from the "," a treatise by Hippocrates. Before Hippocrates, "epidemios", "epidemeo", "epidamos", and other variants had meanings similar to the current definitions of "indigenous" or "endemic." Thucydides' description of the Plague of Athens is considered one of the earliest accounts of a disease epidemic. By the early 17th century, the terms endemic and epidemic referred to contrasting conditions of population-level disease, with the endemic condition at low rates of occurrence and the epidemic condition widespread.
Endoscope
An endoscope is an illuminated optical, typically slender and tubular instrument (a type of borescope) used to look deep into the body and used in procedures called an endoscopy. "Endo" is Greek for "within" while "scope" comes from the Greek word "skopos" meaning to target or look out. It is used to examine the internal organs like the throat or esophagus. Specialized instruments are named after their target organ. Examples include the cystoscope (bladder), nephroscope (kidney), bronchoscope (bronchus), arthroscope (joints) and colonoscope (colon), and laparoscope (abdomen or pelvis). They can be used to examine visually and diagnose, or assist in surgery such as an arthroscopy.
Exercise
Continuous aerobic exercise can induce a transient state of euphoria, colloquially known as a "runner's high" in distance running or a "rower's high" in crew, through the increased biosynthesis of at least three euphoriant neurochemicals: anandamide (an endocannabinoid), β-endorphin (an endogenous opioid), and phenethylamine (a trace amine and amphetamine analog).
Enzootic
Enzootic is the non-human equivalent of endemic and means, in a broad sense, "belonging to" or "native to", "characteristic of", or "prevalent in" a particular geography, race, field, area, or environment; native to an area or scope.
Lake Eyre basin
The Lake Eyre basin ( ) is a drainage basin that covers just under one-sixth of all Australia. The Lake Eyre Basin is the largest endorheic basin in Australia and amongst the largest in the world, covering about , including much of inland Queensland, large portions of South Australia and the Northern Territory, and a part of western New South Wales.
Tricho-hepato-enteric syndrome
Tricho-hepato-enteric syndrome (THE), also known as syndromic or phenotypic diarrhea, is an extremely rare congenital bowel disorder which manifests itself as intractable diarrhea in infants with intrauterine growth retardation, hair and facial abnormalities. Many also have liver disease and abnormalities of the immune system. The associated malabsorption leads to malnutrition and failure to thrive.
Sleep paralysis
The night hag is a generic name for a fantastical creature from the folklore of various peoples which is used to explain the phenomenon of sleep paralysis. A common description is that a person feels a presence of a supernatural malevolent being which immobilizes the person as if sitting on his/her chest. Various cultures have various names for this phenomenon and/or supernatural character. For example, sleep paralysis is referred to as a "Pandafeche" attack in Italy.
Enteric coating
An enteric coating is a polymer barrier applied on oral medication that prevents its dissolution or disintegration in the gastric environment. This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine). Some drugs are unstable at the pH of gastric acid, and need to be protected from degradation. Enteric coating is also an effective method to obtain drug targeting (such as gastro-resistant drugs). Other drugs such as some anthelmintics may need to reach a high concentration in a specific part of the intestine. Enteric coating may also be used during studies as a research tool to determine drug absorption. Enteric coated medications pertain to the "delayed action" dosage form category. From a pharmacological point of view the term "enteric coating" is not entirely correct, as gastric resistance can be also obtained by adding enteric polymeric systems to the matrix of the dosage form. Tablets, mini-tablets, pellets and granules (usually filled into capsule shells) are the most common enteric-coated dosage forms.
Mosaic
The word "mosaic" is from the Italian "mosaico" deriving from the Latin "mosaicus" and ultimately from the Greek "mouseios" meaning "belonging to the Muses", hence artistic. Each piece of material is a Tessera (plural: "tesserae"). The space in between where the grout goes is an interstice. Andamento is the word used to describe the movement and flow of Tesserae. The 'opus', the Latin for ‘work’, is the way in which the pieces are cut and placed.
Surco Intrabético
The Intrabaetic Basin is a series of intermontane basins that separate the Penibaetic System to its south from the Subbaetic System to the north. These basins run more or less parallel to the Mediterranean coast. Together, these valleys constitute a route from western Andalusia and the valley of the Guadalquivir to the Spanish Levante, the eastern Mediterranean coastal region of Spain. From west to east, the basins of the Depression of Ronda, the Hoya of Antequera, the Depression of Granada, the Hoya of Guadix, the Hoya of Baza, the Hoya of Huéscar, and the Hoya of Lorca.
Psychedelic drug
Aldous Huxley had suggested to Humphry Osmond in 1956 his own coinage "phanerothyme" (Greek "phaneroein-" visible + Greek "thymos" soul, thus "visible soul"). Recently, the term entheogenic has come into use to denote the use of psychedelic drugs in a religious/spiritual/mystical context.
Relative energy deficiency in sport
Amenorrhea, defined as the cessation of a woman’s menstrual cycle for more than three months, is the second disorder in the Triad. Weight fluctuations from dietary restrictions and/or excessive exercise affect the hypothalamus’s output of gonadotropic hormones. Gonadotropic hormones “stimulate growth of the gonads and the secretion of sex hormones.” (e.g. gonadotropin-releasing hormone, lutenizing hormone and follicle stimulating hormone.) These gonadotropic hormones play a role in stimulating estrogen release from the ovaries. Without estrogen release, the menstrual cycle is disrupted. Exercising intensely and not eating enough calories can lead to decreases in estrogen, the hormone that helps to regulate the menstrual cycle. As a result, periods may become irregular or stop altogether.
EC-hippocampus system
The entorhinal cortex and its links to the hippocampus have been implicated in the generation of seizures in temporal lobe epilepsy, one of the most common forms of epilepsy. This, coupled with the rich innervation of the hippocampus, is the reason why the EC is so widely studied by neurophysiologists and neuropharmacologists.
Endothelium
Endothelial dysfunction, or the loss of proper endothelial function, is a hallmark for vascular diseases, and is often regarded as a key early event in the development of atherosclerosis. Impaired endothelial function, causing hypertension and thrombosis, is often seen in patients with coronary artery disease, diabetes mellitus, hypertension, hypercholesterolemia, as well as in smokers. Endothelial dysfunction has also been shown to be predictive of future adverse cardiovascular events, and is also present in inflammatory disease such as rheumatoid arthritis and systemic lupus erythematosus. One of the main mechanisms of endothelial dysfunction is the diminishing of nitric oxide, often due to high levels of asymmetric dimethylarginine, which interfere with the normal L-arginine-stimulated nitric oxide synthesis and so leads to hypertension. The most prevailing mechanism of endothelial dysfunction is an increase in reactive oxygen species, which can impair nitric oxide production and activity via several mechanisms. The signalling protein ERK5 is essential for maintaining normal endothelial cell function. A further consequence of damage to the endothelium is the release of pathological quantities of von Willebrand factor, which promote platelet aggregation and adhesion to the subendothelium, and thus the formation of potentially fatal thrombi.
Laennec's cirrhosis
Laennec's cirrhosis, also known as portal cirrhosis, alcoholic cirrhosis, fatty cirrhosis, or atrophic cirrhosis, is named after René Laennec, a French physician and the inventor of the stethoscope. It is a disease of the liver in which the normal lobular architecture is lost, with fibrosis (scarring) and later nodular regeneration. Laennec's cirrhosis can be associated with inflammatory polyarthritis, most commonly affecting the shoulders, elbows and knees. Osteoporosis, soft tissue swelling in peripheral joints and sometimes calcific periathritis are seen.
Aeneas
Aeneas is the Latin spelling of Greek Αἰνείας ("Aineías"). In the Homeric Hymn to Aphrodite, Aeneas is first introduced with Aphrodite naming him Αἰνείας ("Aineías") for the αὶνóν ἄχος ("terrible grief") he caused her, where "Aineías" derives from the adjective αὶνóν ("ainon", meaning "terrible"). It is a popular etymology for the name, apparently exploited by Homer in the Iliad. Later in the Medieval period there were writers who held that, because the Aeneid was written by a philosopher it is meant to be read philosophically. As such, in the "natural order", the meaning of Aeneas' name combines Greek "ennos" ("dweller") and "demas" ("body"), which becomes "ennaios", meaning "in-dweller" (i.e. as a god inhabiting a mortal body). However, there is no certainty regarding the origin of his name.
Transparency (linguistic)
Semantic transparency is a descriptive phrase that has been used in linguistics to describe endocentric compounds. Endocentric compound words are those whose whole meaning can be figured out by an analysis of its parts or "morphemes". An example of an endocentric compound is the word "car-wash". By contrast, some compound words are exocentric, meaning their whole meaning cannot be established by an analysis of parts; for example, the word "hogwash". Exocentric words are also known as semantically opaque.

Enterohepatic circulation
Enterohepatic circulation refers to the circulation of biliary acids, bilirubin, drugs or other substances from the liver to the bile, followed by entry into the small intestine, absorption by the enterocyte and transport back to the liver. Enterohepatic circulation is an especially important concept in the field of toxicology as many lipophilic xenobiotics undergo this process causing repeated liver damage.
Amenorrhea
Anti-psychotic drugs used to treat schizophrenia have been known to cause amenorrhoea as well. New research suggests that adding a dosage of Metformin to an anti-psychotic drug regimen can restore menstruation. Metformin decreases resistance to the hormone insulin, as well as levels of prolactin, testosterone, and lutenizing hormone (LH). Metformin also decreases the LH/FSH ratio. Results of the study on Metformin further implicate the regulation of these hormones as a main cause of secondary amenorrhoea.
Endocrine disease
Endocrine disorders are often quite complex, involving a mixed picture of hyposecretion and hypersecretion because of the feedback mechanisms involved in the endocrine system. For example, most forms of hyperthyroidism are associated with an excess of thyroid hormone and a low level of thyroid stimulating hormone.
In endocrinology, medical emergencies include diabetic ketoacidosis, hyperosmolar hyperglycemic state, hypoglycemic coma, acute adrenocortical insufficiency, phaeochromocytoma crisis, hypercalcemic crisis, thyroid storm, myxoedema coma and pituitary apoplexy.
Hyperaldosteronism
In endocrinology, the terms 'primary' and 'secondary' are used to describe the abnormality (e.g., elevated aldosterone) in relation to the defect, "i.e.", the tumor's location. Hyperaldosteronism can also be caused by plant poisoning, where the patient has been exposed to too much licorice. Licorice is a perennial herb that is used in making candies and in cooking other desserts because of its sweet taste. It contains the chemical glycyrrhizin, which has medicinal uses, but at higher levels it can be toxic. Through inhibition of 11-beta-hydroxysteroid dehydrogenase type 2 (11-beta-HSD2), glycyrrhizin allows cortisol to activate mineralocorticoid receptors (MR) in the kidney. This severely potentiates mineralocorticoid receptor mediated renal sodium reabsorbtion, due to much higher circulating concentrations of cortisol compared to aldosterone. This, in turn, expands the extracellular volume, increases total peripheral resistance and increases arterial blood pressure. The condition is termed pseudohyperaldosteronism.
Diarrhea
Osmotic diarrhea occurs when too much water is drawn into the bowels. If a person drinks solutions with excessive sugar or excessive salt, these can draw water from the body into the bowel and cause osmotic diarrhea. Osmotic diarrhea can also be the result of maldigestion (e.g. pancreatic disease or coeliac disease), in which the nutrients are left in the lumen to pull in water. Or it can be caused by osmotic laxatives (which work to alleviate constipation by drawing water into the bowels). In healthy individuals, too much magnesium or vitamin C or undigested lactose can produce osmotic diarrhea and distention of the bowel. A person who has lactose intolerance can have difficulty absorbing lactose after an extraordinarily high intake of dairy products. In persons who have fructose malabsorption, excess fructose intake can also cause diarrhea. High-fructose foods that also have a high glucose content are more absorbable and less likely to cause diarrhea. Sugar alcohols such as sorbitol (often found in sugar-free foods) are difficult for the body to absorb and, in large amounts, may lead to osmotic diarrhea. In most of these cases, osmotic diarrhea stops when the offending agent (e.g. milk, sorbitol) is stopped.
Endozepine
Endozepines are endogenous compounds with benzodiazepine like effects. They have been linked to hepatic encephalopathy and have controversially been linked to some cases of recurrent stupor. Initially, the key diagnostic test is stupor which is sensitive to the benzodiazepine receptor antagonist flumazenil in the absences of exogenous benzodiazepines.
Dolichodouglas
A Dolichodouglas (word derived from ancient Greek Δόλιχος (dolichos), the long distance in running and the Douglas' pouch) is the medical term describing an abnormally profound Douglas' pouch (recto-uterine pouch). It may be congenital or acquired. The increased depth of the Douglas' pouch brings it in close anatomical contact with the posterior vaginal wall. Therefore, intestinal loops may apply pressure to this wall, causing a condition known as enterocele, which presents as an outpouching on the posterior vaginal wall. This can be felt and seen during pelvic exam.
Endorheic basin
Other endorheic lakes and basins in Asia include:Australia, being very dry and having exceedingly low runoff ratios due to its ancient soils, has many endorheic drainages. The most important are:
Large endorheic regions in Africa are located in the Sahara Desert, the Kalahari Desert, and the East African Rift:Many small lakes and ponds in North Dakota and the Northern Great Plains are endorheic; some of them have salt encrustations along their shores.
Endorheic basin
Endorheic regions, in contrast to exorheic regions which flow to the ocean in geologically defined patterns, are closed hydrologic systems. Their surface waters drain to inland terminal locations where the water evaporates or seeps into the ground, having no access to discharge into the sea. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest saline inland sea.
Open and closed lakes
Open lakes typically have stable levels which do not fluctuate because input is always matched by outflow to rivers downstream. If more water enters an open lake than was previously leaving it, then more water will leave the lake. The drainage from an open lake, like that from ordinary rivers, is referred to as exorheic (from the Greek "exos", outside and "rhein", to flow).
