Eicosapentaenoic acid
Eicosapentaenoic acid One of the principal omega-3 fatty acids. Abbreviated EPA. The body has a limited ability to manufacture EPA by converting the essential fatty acid, alpha-linolenic acid (ALA) which is found in flaxseed oil, canola oil or walnuts.
RELATED TERMS--------------------------------------
EPA
Eicosapentaenoic acid is a polyunsaturated essential fatty acid. OmegaRx fish oil contains 40 percent EPA. EPA enhances the production of "good" eicosanoids and inhibits the production of Arachidonic Acid (AA). The higher the level of EPA in the diet, the more your cells will be induced to produce more good "eicosanoids"; the high levels of EPA also hinder the production of "bad" eicosanoids. EPA promotes good physical well-being, including increased circulation, and promotes a healthy immune system. EPA is also a powerful anti-inflammatory.
Essential
1. Something that cannot be done without. 2. Required in the diet, because the body cannot make it. As in an essential amino acid or an essential fatty acid. 3. Idiopathic. As in essential hypertension.
SIMILAR TERMS--------------------------------------
Eicosanoid
A hormone derived from a polyunsaturated fat. Eicosanoids are made by every cell in the body. As autocrine hormones, they are constantly produced by the cell to sample the external environment. "Good" eicosanoids generate AMP.
PREVIOUS AND NEXT TERMS--------------------------------------
EGF
Epidermal growth factor. A polypeptide (small protein) that is a powerful mitogen. (It stimulates cells to enter mitosis, cell division. ) EGF promotes cell growth and differentiation, is essential in embryogenesis, and is important in wound healing. It is produced by many normal cell types and is made in large amounts by some tumors. The EGF gene is on chromosome 4q25 (whereas the gene for its receptor, EGFR, is on chromosome 7). The kidney is the main source of circulating EGF. EGF is also known as urogastrone (URG).
Egg sac
The "egg sac" or ovary is one of a pair of reproductive glands in women. They are located in the pelvis, one on each side of the uterus. Each ovary is about the size and shape of an almond. The ovaries have two functions: production of eggs (ova) and female hormones. Each month, during the menstrual cycle, an egg is released from one ovary. The egg travels from the ovary through a fallopian tube to the uterus.
Ehlers-Danlos syndrome
A heritable disorder of connective tissue with easy bruising, joint hypermobility (loose joints), skin laxity, and weakness of tissues. There are a number of different types of Ehlers-Danlos syndrome (EDS) which share the foregoing features but can be categorized into at least nine different types.
Ehlers-Danlos syndrome, dermatosparaxis type
A genetic disorder characterized by extremely fragile and sagging skin caused by mutation in the ADAMTS2 gene. People with this form of Ehlers-Danlos syndrome have soft, doughy skin that is very fragile and bruises easily. The skin sags and wrinkles, and extra (redundant) folds of skin may be present as children get older. Joints are very loose, which can delay the development of motor skills such as sitting, standing, and walking. Infants with the condition are born with a soft out-pouching called a hernia around the belly-button. Other symptoms include a small chin, a blue tinge to the part of the eyeball that is usually white (the sclera), and mild overgrowth of body hair.
Ehrlichiosis
An acute (abrupt onset) disease, clinically similar to Rocky Mountain spotted fever with high fever, headache, malaise, and muscle pain but without a rash. Laboratory features include leukopenia (low white blood cell count), thrombocytopenia (low platelet count), mild anemia, and elevation in the levels of hepatic aminotransferase enzymes. Clinical symptoms and laboratory abnormalities respond promptly to therapy with the antibiotics tetracycline or doxycycline, and the majority of patients become afebrile within 24 to 48 hours after the start of such treatment. The diagnosis of ehrlichiosis rests on the detection of ehrlichia either by direct means or by the indirect means of serologic studies. Three methods are available for detection: inspection of peripheral-blood smears, PCR testing, and tissue culture.
Eicosapentaenoic acid
Eight-day measles
An acute highly contagious viral disease with fever, runny nose, cough, red eyes, and a spreading skin rash. The eight-day measles is the ordinary measles, also known as rubeola, a potentially disastrous disease. Measles may be complicated by ear infections, pneumonia, encephalitis (that can cause convulsions, mental retardation. and even death), the sudden onset of low blood platelet levels with severe bleeding (acute thrombocytopenic purpura) or a chronic brain disease that occurs months to often years after an attack of measles (subacute sclerosing panencephalitis). During pregnancy measles may trigger miscarriages or premature delivery. Measles can be prevented through vaccination. The disease is also called the hard measles and (depending on how long you think it lasts) the seven- day measles, the nine-day measles, or the ten-day measles, and morbilli.
Eighth cranial nerve
The eighth cranial nerve is the vestibulocochlear nerve. The vestibulocochlear nerve is responsible for the sense of hearing and it is also pertinent to balance, to the body position sense. Problems with the vestibulocochlear nerve may result in deafness, tinnitus (ringing or noise in the ears), dizziness, vertigo and vomiting. The 12 cranial nerves, the vestibulocochlear nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column.
Eisoptrophobia
An abnormal and persistent fear of mirrors. Sufferers experience undue anxiety even though they realize their fear is irrational. Because their fear often is grounded in superstitions, they may worry that breaking a mirror will bring bad luck or that looking into a mirror will put them in contact with a supernatural world inside the glass.
Ejaculatory duct
A canal in the male formed by union of the vas deferens and the duct from the seminal vesicle. The ejaculatory duct passes through the prostate. Semen passes through them at the time of ejaculation.
ELA2
The gene encoding the enzyme elastase 2 (neutrophilic elastase). Mutations in ELA2 cause cyclic neutropenia.
