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

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.

Deuteration of catecholamines, catecholamine metabolites and tryptophan metabolites
Journal of Labelled Compounds and Radiopharmaceuticals, 1978AbstractThe 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

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.

Catecholamines and Their Receptors
1997This chapter provides an overview of catecholamines and their receptors, and possible catecholaminergic mechanisms by which central structures can contribute to the regulation of the cerebral circulation. The possibility of catecholamine-induced changes in the cerebral circulation was first addressed concomitant with the role of perivascular ...

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
