The characteristics of the nuclear T3 receptor in the liver of the chick embryo were studied from incubation day 18 until day 1 posthatching. Treatment of the nuclei with 3 mol.l-1 MgCl2, which removed the endogenously bound hormone, was used in order to determine the total amount of receptors. The affinity constant Ka decreased between incubation day 18 (0.996 +/- 0.276.10(9) M-1) and day 19 (...

Experiments were conducted to understand the effects of thyroid hormones and thiourea (TU) on otolith growth during metamorphosis of leptocephali. TU is an anti-thyroid hormone drug that inhibits the production of thyroxine (T4) and triiodothyronine (T3) in the thyroid tissue. Fully grown leptocephali of tarpon Megalops cyprinoides collected at the mouth of the Gong-Shy-Tyan Brook, N Taiwan, we...

Abstract This research study tested an intervention, based on autonomous teams and the service co-creation approach, to improve social inclusion self-determination (as indicators of quality life) people with intellectual disability. Members (professionals, disability, family members) cooperated plan carry out a project. A total 72 participated (experimental condition). Each team designed its ac...

Typical Near East mitochondrial haplotypes of the T2 lineage were found in one cattle metacarpus sample from the Roman period and in two present-day Evolène cattle in Switzerland. Sequences from eight additional Evolène and four Raetian Grey aligned to the European haplotype T3. Analysis of nucleotide diversity within the mitochondrial D-loop of both studied Swiss cattle breeds revealed high ha...

introduction: previous studies have shown that ghrelin inhibits the activity of hypothalamus –pituitary – thyroid (h–p-t) axis. it is also proved that ghrelin increases appetite via agouti related protein and neuropeptide y pathway, decreases t3 & t4 secretion and inhibits serotonin release from hypothalamic synaptosomes. serotonin may interact with ghrelin in control of thyroid hormones secret...

The present study was carried out to observe the effect on performance, nutrient utilization, plasma enzymes and hormones in growing Sahiwal calves fed with three levels of proteins in the form of total mixed rations (TMRs). Fifteen male Sahiwal calves (12-18 month age) were distributed into three equal groups (147.35 ± 5.46 kg) and were fed on isocaloric diets containing different protein leve...

background: the intensity and duration of speech diffi culty inherently associated with lingual therapy is a signifi cant issue of concern in orthodontics. this study was designed to evaluate and to compare the duration of changes in speech between labial and lingual orthodontics. materials and methods: a prospective longitudinal clinical study was designed to assess speech of 24 patients under...

To evaluate the effect of long-term clomipramine administration on the hypothalamic-pituitary-thyroid axis in healthy dogs, 14 healthy adult dogs were enrolled in a prospective study. Clomipramine (3 mg/kg PO q12h) was administered to all dogs beginning on day 0, and continued for 112 days. Serum total thyroxine (T4), free thyroxine (fT4), 3,5,3'-triiodothyronine (T3), 3,3',5'-triiodothyronine ...

Abstract A rapid hybrid solid phase extraction (HybridSPE®) protocol tailored to liquid chromatography–electrospray ionization tandem mass spectrometry (LC–ESI–MS/MS) analysis, was developed for the determination of four thyroid hormones, L-Thyroxine (T4), 3,3?,5-triiodo-L-thyronine (T3), 3,3?,5?-triiodo-L-thyronine (rT3) and 3,3?-diiodo-L-thyronine (T2) in blood plasma from Glaucous gulls (Lar...
