Bereavement and catecholamines
Journal of Psychosomatic Research, 1986Urinary catecholamine output was studied in 59 middle-aged and elderly persons who were either acutely bereaved (n = 39) or threatened with the loss of a spouse (n = 20). The study was done with the hypothesis that urinary catecholamine output would be elevated among the bereaved subjects both in comparison to norms in the literature for non-stressed ...

Catecholamines and Catecholamine Metabolites
2020Measurement of catecholamines and their metabolites may be indicated when evaluating patients with hypertension, dizziness, syncope, or “spells” with some combination of headache, abdominal pain, sweating, tachycardia or palpitations, anxiety, pallor or flushing, and hypertension.

American Journal of Obstetrics and Gynecology, 1983
Experimental data from fetal human and animal research suggest that the fetal sympathoadrenal system, composed of the adrenal medulla, sympathetic neurons, and extra-adrenal chromaffin tissue functions from early fetal life to maintain fetal homeostasis. The extra-adrenal chromaffin tissue undergoes maturation at 9 to 11 weeks of gestation, whereas the

Catecholamines and the Thyroid
Thyroid, 1990Low 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.

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, 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.

Journal of Molecular and Cellular Cardiology, 1985
The morphologic-functional correlative studies that we have carried out in the past 25 years with the various catecholamines have served as an example for analyzing myocardial reaction patterns and the reactions of the cardiac muscle cells to insult.

This and That: on color and catecholamines
Trends in Pharmacological Sciences, 1989A 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.

Catecholamines and Tryptamines
1969Catecholamines are represented in the vertebrate nervous system most notably by noradrenaline (NA) and dopamine (DA), but also by the precursor compounds and related ones. Tryptamines are represented primarily by 5-hydroxytryptamine (5-HT or serotonin), but tryptamine itself has been detected there as well.
