Thyroid hormone resistance (THR) is a rare syndrome of reduced end organ sensitivity. Patients with THR have elevated serum free thyroxine (FT4), free triiodothyronine (FT3), but normal or slightly elevated serum thyrotropin values. The characteristic clinical feature is goitre without symptoms and metabolic consequences of thyroid hormone excess. THR can be classified on the basis of tissue re...

Phosphorylation plays an important role in regulation of protein kinase C delta (PKCdelta). To date, three Ser/Thr residues (Thr 505, Ser 643, and Ser 662) and nine tyrosine residues (Tyr 52, Tyr 64, Tyr 155, Tyr 187, Tyr 311, Tyr 332, Tyr 512, Tyr 523, and Tyr 565) have been defined as regulatory phosphorylation sites for this protein (rat PKCdelta numbering). We combined doxycycline-regulated...

PURPOSE To examine energy expenditure at rest and during a single therapeutic horseback riding (THR) session in children with moderate to severe motor impairments. METHODS Heart rate (HR), oxygen uptake (.VO2), and minute ventilation (.VE) were measured continuously during a 10-minute rest period and during a typical THR session. RESULTS Seven children (4 males, mean age 12.3 ± 3.5 years) c...

Recent genetic, biochemical and structural studies have established that eukaryotic-like Ser/Thr protein-kinases are critical mediators of developmental changes and host pathogen interactions in bacteria. Although with lower abundance compared to their homologues from eukaryotes, Ser/Thr protein-kinases are widespread in gram-positive bacteria. These data underline a key role of reversible Ser/...

Retinoid-like receptors play a central role in hormonal responses by forming heterodimers with other nuclear hormone receptors. In this study we have identified the peroxisome proliferator-activated receptor (PPAR) as a new thyroid hormone receptor (THR) auxiliary nuclear protein, heterodimerizing with THR in solution. Although these heterodimers do not recognize a classical thyroid hormone res...
