This prospective case-controlled study investigated the role of the pituitary-thyroidal axis in the prediction of mortality in dogs. Serum thyrotropin, thyroxine and free thyroxine were measured at admission and daily until death or discharge in dogs ill with parvoviral diarrhoea. Serum thyroxine and free thyroxine in ill dogs were significantly lower than in controls and also significantly low...
The medial basal hypothalamus was isolated from the remainder of the brain of the rat using a Halász knife. Ten to 14 days after the surgical procedure the concentration of thyrotropin-releasing hormone within the island of hypothalamic tissue was 76% lower than in tissue from sham-operated control rats. Thus, much of the thyrotropin-releasing hormone that is normally present in the medial basa...
Various lipids extracted from bovine thyroid glands were tested for their ability to affect the binding of 125I-labeled thyrotropin to bovine thyroid membranes. The most potent inhibitors were the acidic phospholipids in the order cardiolipin greater than phosphatidylglycerol greater than phosphatidylinositol greater than phosphatidylserine. Other phospholipids, neutral lipids, and neutral glyc...
The activating mutation BRAF is the most prevalent genetic alteration in papillary thyroid carcinomas (PTC). It is associated with advanced PTCs, suggesting that this oncoprotein confers thyroid cancers with more aggressive properties. BRAF is also observed in thyroid micropapillary carcinomas and may thus be an early event in tumor development. To explore its biological consequences, we establ...
FRTL-5 rat thyroid cells grown and maintained in a medium containing 0.05 nM thyrotropin have a 10-fold higher number of alpha 1-adrenergic receptors on their cell surface than FRTL-5 cells maintained in the absence of thyrotropin in their medium. The increased number of alpha 1-adrenergic receptors, measured as increased specific [3H]prazosin binding per microgram of DNA, is not associated wit...
In a previous study of a representative population of 460 men of age 70, we found that the free thyroxin (free T4) concentration was negatively correlated to body mass. In the present study we analyzed other indicators of thyroid function in relation to body mass and body mass index in 181 individuals without any disease or medication influencing thyroidal homeostasis or body mass. There was a ...
Various autoantibodies have been reported to be detected during the progression of infectious mononucleosis. We observed a case of infectious mononucleosis due to Epstein-Barr virus primary infection for 2 months, and noticed the transiently increased titer of thyrotropin receptor autoantibodies detected at the acute phase on the 3rd day after admission. At that time, real-time quantitative PCR...
