catecholamine comes to mind- I had a 24 hour pee test for that once-check this out-D
Catecholamine: Pronounced cat·e·chol·amine. An amine derived from the amino acid tyrosine -- examples include epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine -- that act as hormones or neurotransmitters. There are a number of disorders involving catecholamines, including neuroblastoma, pheochromocytoma, chemodectina, the familial paraganglioma syndrome, dopamine-ß-hydroxalase deficiency, and tetrahydrobiopterin deficiency
Neuroblastoma is the second most common solid tumor in childhood (after brain tumors). It usually produce catecholamines. The catecholamine metabolites vanillylmandelic acid and homovanillic acid can be measured quantitatively in the urine as a test for the disease.
Pheochromocytoma is a benign tumor derived from the adrenal medulla or sympathetic paraganglia. The tumor secretes epinephrine and norepinephrine. These catecholamines cause attacks of hypertension, headache, nausea and vomiting, sweating, pallor and severe apprehension.
Chemodectoma is another benign tumor of the chemoreceptor system, the most common types being the carotid body tumor and the glomus jugulare tumor. Also known as nonchromaffin paraganglioma.
Familial paraganglioma syndrome is an unusual familial disease involving slow-growing benign tumors -- paragangliomas, glomus tumors, or chemodectomas -- predominantly in the head and neck region. The gene for the disease is on chromosome 11q23. The tumors may lead to disfiguring local swellings, cranial nerve injury, or involvement of the base of the skull and may cause dysphonia, aspiration, hearing loss, dysphagia, tinnitus, pain, persistent cough, and shoulder weakness (due to tumor encroachment on cranial nerves). All individuals with hereditary paragangliomas inherit the disease gene from their father. This is consistent with genomic imprinting: the maternally derived gene is inactivated during oogenesis and can be reactivated only during spermatogenesis.
Dopamine-ß-hydroxalase deficiency is a congenital form of severe orthostatic hypotension caused by complete absence of the enzyme dopamine-ß-hydroxalase. During childhood impaired exercise tolerance, fatigue, and episodes of syncope (fainting) are common. Symptoms from orthostatic hypotension become worse in late adolescence and in early adulthood.
Tetrahydrobiopterin deficiency is a genetic defect of enzymes required for the synthesis (production) of catecholamines, resulting in a deficiency in neurotransmitters. Symptoms begin between two and eight months of age, and include unstable body temperature, swallowing difficulties, hypersalivation, pinpoint pupils, ptosis of the eyelids, decreased mobility, drowsiness, and irritability.

while i became into making waiting scholars for the the two the Cambridge and Michigan college decrease and skillability exams, consistancy interior the compositions and oral interviews mattered notably. Now the decrease levelled national exams have been all consistent with British English, so right here you have a pupil who has been studying to spell a definite far greater than a minimum of a 5 365 days era, and all the surprising they are anticipated to bear in mind all the diversities for the main mandatory exams of all. Cambridge college became into greater strict in marking the diversities than Michigan became into, however the Cambridge exams are greater theory-based, and the Michigan spotlight an ease with use interior the 2d language. The greater moderen London college exams are hit or omit, spelling does not even count variety if it does not get rid of from the information of what has been written. to respond to your question, it is going the two procedures...yet you're dazzling to be aggravated at being corrected by using people who do not understand there are a honest volume of variations between the two languages (British and American English) and that the two are dazzling. as quickly as I see questions or solutions i will incredibly comprehend because of the fact of spelling errors, it makes my epidermis crawl, yet i attempt to bear in mind this could properly be a guy or woman who remains interior the approach of studying English...the only forgivable excuse. and a few human beings have been purely on no account waiting to further their guidance and/or on no account mandatory to write down lots interior the roles they have had by using the years, i don't concepts their making errors, the two...that's comprehensible. So are variety-o's. some peple are purely extreme dickwads, yaknows? Reall hi and mitey and think of there warm shite an all dat, and each physique else shud be and seem and scent and communicate and write purely like'em...

You're thinking of catecholamines.
