| syndrome, brown's | An ophthalmology (eye) problem. Brown's syndrome presents at birth (congenitally) and is characterised by an inability to elevate the eyeball when also trying to move the eyeball to the outside. (12 Dec 1998) |

| syndrome, conn's | Overproduction of the hormone aldosterone from a tumour containing tissue like that in the outer portion (cortex) of the adrenal gland. Excess aldosterone (pronounced al-do-ster-one) results in low potassium levels (hypokalaemia), underacidity of the body (alkalosis), muscle weakness, excess thirst (polydipsia), excess urination (polyuria), and high blood pressure (hypertension). Also called primary aldosteronism and hyperaldosteronism. Named after the american physician jerome w. Conn. (12 Dec 1998) |
| syndrome, cracked tooth | A toothache caused by a broken tooth (tooth fracture) without associated cavity or advanced gum disease. Biting on the area of tooth fracture can cause severe sharp pains. These fractures are usually due to chewing or biting hard objects such as hard candies, pencils, nuts, etc. Sometimes, the fracture can be seen by painting a special dye on the cracked tooth. Treatment usually is to protect the tooth with a crown. However, if placing a crown does not relieve pain symptoms, a root canal procedure may be necessary. (12 Dec 1998) |
| syndrome, creutzfeldt-jakob | Better known as creutzfeldt-jakob disease (cjd). A dementing disease of the brain. It is believed due to an unconventional (not a bacteria or virus), transmissible agent called a prion. Symptoms of cjd include forgetfulness, nervousness, jerky trembling hand movements, unsteady gait, muscle spasms, chronic dementia, balance disorder, and loss of facial expression. Cjd is classified as a spongiform encephalopathy. most cases occur randomly (sporadically), but inherited forms exist. There is neither treatment nor cure for cjd. Other names for cjd include jakob-creutzfeldt disease and spastic pseuodoparalysis. (12 Dec 1998) |
| syndrome, cushing's | The constellation of symptoms and signs caused by an excess of cortisol hormone. Cushing syndrome is an extremely complex hormonal condition that involves many areas of the body. Common symptoms are thinning of the skin, weakness, weight gain, bruising, hypertension, diabetes, thin weak bones (osteoporosis), facial puffiness, and in women cessation of periods. Ironically, one of the commonest causes of cushing's syndrome is the administration of cortisol-like medications for the treatment of diverse diseases. All other cases of cushing's syndrome are due to excess production of cortisol by the adrenal gland including 1) an abnormal growth of the pituitary gland, which stimulates the adrenal gland, 2) a benign or malignant growth within the adrenal gland itself, which produces cortisol and 3) production within another part of the body (ectopic production) of a hormone that directly or indirectly stimulates the adrenal gland to make cortisol. Neurosurgeon harvey cushing (1869-1939) described hyperadrenocorticism (excessive production of cortisol by the adrenal gland) due quite specifically to an acth-secreting pituitary adenoma, a benign pituitary tumour that puts out acth (adrenocorticotropic hormone) which, in turn, drives (or overdrives) the adrenal gland to overproduce cortisol.

| syndrome, digeorge | This disorder is characterised by (1) low blood calcium levels (hypocalcaemia) due to underdevelopment (hypoplasia) of the parathyroid glands which control calcium; (2) underdevelopment (hypoplasia) of the thymus, an organ behind the breastbone in which lymphocytes mature and multiply; and (3) defects of the heart involving the outflow tracts from the heart. most cases of dgs are due to a microdeletion in chromosome band 22q11.2. A small number of cases have defects in other chromosomes, notably 10p13. Named after the american paediatric endocrinologist angelo more than digeorge. Other names for dgs include the third and fourth pharyngeal pouch syndrome and hypoplasia of the thymus and parathyroids. (12 Dec 1998) |
| syndrome, down | A common disorder due to a chromosome abnormality and specfically due to an extra chromosome number 21 (trisomy 21). Down syndrome includes mental retardation, a characteristic face, and multiple malformations. It is associated with a major risk for heart problems, a lesser risk of duodenal atresia (part of the intestines not developed), and a minor but still significant risk of acute leukaemia. The name down syndrome comes from the 19th century english doctor langdon down, a misnomer since he was curiously enough not the first person to describe the condition and, in great error, attributed the condition to a reversion to the mongoloid race. Hence, the old name mongolism, now considered slang. (12 Dec 1998) |
| syndrome, dumping | A group of symptoms that occur when food or liquid enters the small intestine too rapidly. These symptoms include cramps, nausea, diarrhoea, and dizziness. (12 Dec 1998) |
| syndrome, edwards | This is trisomy 18 syndrome. There are three instead of the normal two chromosomes 18. Children with this condition have multiple malformations and mental retardation due to the extra chromosome 18. The children characteristically have low birth weight, small head (microcephaly), small jaw (micrognathia), malformations of the heart and kidneys, clenched fists with abnormal finger positioning, and malformed feet. The mental retardation is profound with the iq too low to even test. Nineteen out of 20 (95%) of these children die before their first birthday. The condition is named after the british physician and more than geneticist john edwards who discovered the extra chromosome in 1960. (12 Dec 1998) |
| syndrome, fish-odour | An inborn error of metabolism associated with an offensive body odour, the smell of rotting fish, due to the excessive excretion of trimethylaminuria (tma) in urine, sweat, and breath. Persons with tma may experience tachycardia (fast heart rate) and severe hypertension (high blood pressure) after eating cheese (which contains tyramine) and after using nasal sprays containing epinephrine. Tma is caused by a mutation (change) in the gene for an enzyme, flavin-containing monooxygenase-3 (fmo3) encoded by a gene on chromosome 1. The fmo3 enzyme metabolises tyramine (which is in cheese). The syndrome is associated with various psychosocial reactions, including social isolation, clinical depression and attempted suicide. (12 Dec 1998) |
| syndrome, floppy baby | Floppy baby syndrome is a general medical reference to an abnormal condition of newborns and infants manifest by inadequate tone of the muscles. Hypotonia (inadequately toned muscles resulting in floppiness) in the newborn period and infancy can be due to a multitude of different neurologic and muscle problems. (12 Dec 1998) |
| syndrome, foetal alcohol | The sum total of a person's problems caused by maternal alcohol intake during pregancy. (12 Dec 1998) |
| syndrome, fragile x | The most common heritable form of mental retardation. Fragile x syndrome is due to mutation (changes) at the fragile x site and so perforce is x-linked (carried on the x chromosome). Although it is usually more severe in males than females, the syndrome is due to a dynamic mutation (a trinucleotide repeat) that can change in length and hence in severity from generation to generation, from person to person, and even within a given person. The fragile x syndrome is also known as the martin-bell syndrome in honor of their discovery of it in 1943. (12 Dec 1998) |

| syndrome, hecht | Inherited disorder transmitted as an autosomal dominant trait in which short tight muscles make it impossible to open the mouth fully or keep the fingers straight when the hand is flexed back. The small mouth creates feeding problems. The hands may be so tightly fisted the infant crawls on the knuckles. Also called the trismus pseudocamptodactyly syndrome. (12 Dec 1998) |
| synthesize |
Synthesis (from the Greek words syn = plus and thesis = position) is commonly understood to be an integration of two or more pre-existing elements which results in a new creation. The term is broad in meaning and can apply to physical, ideological, and/or phenomenological entities. In dialectics, synthesis is the final result of attempts to reconcile the inherent contradiction between thesis and antithesis. ...

| synthetase |
In biochemistry, a ligase is an enzyme that can catalyse the joining of two molecules ("ligation" or "gluing together") by forming a new chemical bond, with accompanying hydrolysis of ATP or other similar molecules. For example, an enzyme that catalyzed this reaction would be a ligase: The common names of ligases often include the word "ligase," such as DNA ligase, an enzyme commonly used in molecular biology laboratories to join together DNA fragments. ...
