| thyroid hormone receptor alpha1 directly controls transcription of the beta-catenin gene in intestinal epithelial cells. | thyroid hormones, t3 and t4, are known regulators of intestine development. the best characterized example is the remodeling of the gastrointestinal tract during amphibian metamorphosis. thyroid hormones act via nuclear receptors, the trs, which are t3-dependent transcription factors. we previously showed that intestinal epithelial cell proliferation is controlled by thyroid hormones and the tralpha gene. to analyze the mechanisms responsible, we studied the expression of genes belonging to and/ ... | 2006 | 16581794 |
| reflex regulation of airway sympathetic nerves in guinea-pigs. | sympathetic nerves innervate the airways of most species but their reflex regulation has been essentially unstudied. here we demonstrate sympathetic nerve-mediated reflex relaxation of airway smooth muscle measured in situ in the guinea-pig trachea. retrograde tracing, immunohistochemistry and electrophysiological analysis identified a population of substance p-containing capsaicin-sensitive spinal afferent neurones in the upper thoracic (t1-t4) dorsal root ganglia (drg) that innervate the airwa ... | 2006 | 16581869 |
| distance determination by giy-yig intron endonucleases: discrimination between repression and cleavage functions. | giy-yig homing endonucleases are modular proteins, with conserved n-terminal catalytic domains connected by linkers to c-terminal dna-binding domains. i-tevi, the t4 phage giy-yig intron endonuclease, functions both in promoting td intron homing, and in acting as a transcriptional autorepressor. repression is achieved by binding to an operator, which is cleaved at 100-fold reduced efficiency relative to the intronless homing site. the linker includes a zinc finger, which functions in distance de ... | 2006 | 16582101 |

| hyperthyroidism and the kidney. | hyperthyroidism and chronic renal failure (crf) are both common diseases of older cats. hyperthyroidism increases gfr by a variety of physiologic effects. chronic renal failure can suppress total t4 concentrations in cats with concurrent hyperthyroidism, and free t4 is not a useful distinguishing test. medical therapy (ie, methimazole) is recommended in cats with pre-existing crf. overt renal failure occurs in approximately 30% of cats treated for hyperthyroidism. it usually occurs within one mo ... | 2006 | 16584026 |
| medical management of hyperthyroidism. | radioiodine is considered the treatment of choice for hyperthyroidism, but in some situations, methimazole therapy is preferred, such as in cats with pre-existing renal insufficiency. methimazole blocks thyroid hormone synthesis, and controls hyperthyroidism in more than 90% of cats that tolerate the drug. unfavorable outcomes are usually due to side effects such as gastrointestinal (gi) upset, facial excoriation, thrombocytopenia, neutropenia, or liver enzyme elevations; warfarin-like coagulopa ... | 2006 | 16584027 |

| tandem mass spectrometry of intact groel-substrate complexes reveals substrate-specific conformational changes in the trans ring. | it has been suggested that the bacterial groel chaperonin accommodates only one substrate at any given time, due to conformational changes to both the cis and trans ring that are induced upon substrate binding. using electrospray ionization mass spectrometry, we show that indeed groel binds only one molecule of the model substrate rubisco. in contrast, the capsid protein of bacteriophage t4, a natural groel substrate, can occupy both rings simultaneously. as these substrates are of similar size, ... | 2006 | 16594706 |
