Antibodies to Catecholamines

Endocrinology, 1976
The haptens p-tyramine and synephrine were conjugated to bovine serum albumin by means of the formaldehyde condensation reaction. These conjugates were emulsified in adjuvant and injected into rabbits. Antiserum was harvested at 10-day intervals after booster injections. The anti-sera were screened by immunodiffusion.

Oxidation chemistry of catecholamines and neuronal degeneration: an update.

Current Medicinal Chemistry, 2011
Aberrant oxidative pathways of catecholamine neurotransmitters, i.e. dopamine and norepinephrine, are an important biochemical correlate of catecholaminergic neuron loss in some disabling neurodegenerative diseases of the elderly, notably Parkinson's ...

Catecholamines and the Thyroid

Thyroid, 1990
Low TSH levels are frequently encountered in patients presenting with goiter. We assayed TSH in 599 goitrous patients who were referred to us for scintigraphy and ultrasonography. When TSH levels were low or when a hot nodule was discovered at scintigraphy, free T3, free T4 and sex hormone-binding globulin (SHBG) were also assayed.

Catecholamines and Vitiligo

Pigment Cell Research, 1992
The levels of some catecholamine metabolites, namely homovanillic acid (HVA), vanil‐mandelic acid (VMA), 3‐methoxytyramine (MT), normetanephrine (NMN), metanephrine (MN), 3,4‐dihydroxy mandelic acid (DOMAC), and 3,4‐dihydroxy phenylacetic acid (DOPAC), have been evaluated in the 24 hr urines of 150 patients affected with different types of vitiligo and

Endocrinology of the stress response.

Annual Review of Physiology, 2005
The stress response is subserved by the stress system, which is located both in the central nervous system and the periphery. The principal effectors of the stress system include corticotropin-releasing hormone (CRH); arginine vasopressin; the ...

This and That: on color and catecholamines

Trends in Pharmacological Sciences, 1989
A series of hexahydro-difenidol (HHD) and hexahydro-sila-difenidol (HHSiD) analogues modified in the amino group, the phenyl ring and in the alkylene chain were investigated for their binding and functional properties at muscarinic M1, M2 and M3 receptors.

Deuteration of catecholamines, catecholamine metabolites and tryptophan metabolites

Journal of Labelled Compounds and Radiopharmaceuticals, 1978
AbstractThe preparation of some deuterium labelled catecholamines, catecholamine metabolites and tryptophan metabolites is described. Simple exchange reactions in DC1/D20 solution or reductions with Li Al D4 were used. The deuterium labelled compounds prepared are suitable for use as internal standards for quantitative mass‐fragmentographic analysis of

Plasma catecholamines in stress and exercise.

Journal of the American Medical Association (JAMA), 1980
A technique was devised to monitor plasma catecholamines in a minimally obtrusive fashion in subjects going about their working activities. There was a disparity between plasma norepinephrine and epinephrine levels in different situations.
