Thyrotropin-secreting pituitary tumors [PDF]
I. Introduction The term “TSH-secreting pituitary tumors” includes two opposite clinical conditions: true thyrotroph neoplasia that results in secondary hyperthyroidism, also called “central hyperthyroidism,” and pituitary hyperplasia resulting from longstanding primary hypothyroidism. The latter condition was first recognized 145 yr ago (1), while the

Functional Divergence of Glycoprotein Hormone Receptors [PDF]
Two lamprey glycroprotein hormone receptors (lGpH-R I and II) highly similar with gnathostome GpH-Rs were cloned from sea lamprey testes and thyroid, respectively.

The Two Faces of Janus: Why Thyrotropin as a Cardiovascular Risk Factor May Be an Ambiguous Target
Elevated concentrations of free thyroid hormones are established cardiovascular risk factors, but the association of thyrotropin (TSH) levels to hard endpoints is less clear.

The 'incidentaloma' of the pituitary gland. Is neurosurgery required? [PDF]
We describe a series of 18 patients with an intrasellar mass incidentally discovered by computed tomography or magnetic resonance imaging. The average size of the mass was 13 mm, with a range from 5 to 25 mm.

Cardiovascular mortality in subclinicalhyperthyroidism: an ongoing dilemma. [PDF]
The association of endogenous subclinical hyperthyroidism (SHyper) with cardiovascular mortality is controversial. This may reflect the different causes of endogenous SHyper in the population studied due to differences in iodine intake, and different ...

The decrease in growth hormone (GH) response after repeated stimulation with GH-Releasing hormone is partly caused by an elevation of somatostatin tonus. [PDF]
Repeated injection of GHRH leads to a decrease in the GH response in normal subjects. Arginine (Arg) stimulates GH secretion by suppression of hypothalamic somatostatin.

Thyroid hormone levels within reference range are associated with heart rate, cardiac structure, and function in middle-aged men and women [PDF]
Background: Triiodothyronine (T3) has many effects on the heart, and marked changes in cardiac function and structure occur in patients with (subclinical) thyroid disease. We investigated whether between-subject variation in thyroid hormone levels within

Thyrotropin reference interval in older adults
It is estimated that by the year 2050, 16% of the world’s population will be 65 years old and above. As the global aging population continues to grow, there is an increasing focus on thyroid disorders among older individuals.
