This study compares the functional consequences of levothyroxine (T4) treatment during pregnancy as well as the acute affects of triiodothyronine (T3) on spontaneous uterine contractile activities observed in vitro. Uterine biopsies were obtained from consenting women undergoing elective caesarean at term (n = 28). Spontaneous contractile activities from T4-treated pregnant women (n = 8) were c...

Experiments were conducted in three successive years in which iodide (I) doses of 1.25, 2.5, 5.0 and 7.5 mg/kg body weight were given to 47 dairy cows during the dry period, compared with 16 control cows on basal diets of 1 ppm I. Effects on cows dosed at 1.25 and 2.5 mg I/kg (50 and 100 ppm dry feed) were not different from controls in terms of vitality of calves, changes in plasma thyroxine (...

Type III iodothyronine deiodinase (D3) catalyzes the inner ring deiodination (IRD) of T4 and T3 to the inactive metabolites rT3 and 3,3'-diiodothyronine (3,3'-T2), respectively. Here we describe the cloning and characterization of complementary DNA (cDNA) coding for D3 in fish (Oreochromis niloticus, tilapia). This cDNA contains 1478 nucleotides and codes for a protein of 267 amino acids, inclu...

This study was undertaken to determine T3 content in red cells by radioimmunoassay. T3 in red blood cells was solubilized fairly from the stroma by hemolysis and red-cell T3 content could be determined directly by radioimmunoassay of the lysate. After hemolysing red cells with an equal volume of distilled water, 0.4 ml of the hemolyzate was used for the assay. The red-cell T3 content was expres...

Pronunciation variation is ubiquitous in the speech signal. Different models of lexical representation have been put forward to deal with speech variability, which differ in the level as well as the nature of mental representation. We present the first mismatch negativity (MMN) study investigating the effect of allophonic variation on the mental representation and neural processing of lexical t...

This study was carried out to determine the dietary supplementation of organic zinc on feed intake (FI), conversion ratio (FCR), egg production (EP), mass (EM) and quality. A total 120 ISA-Brown layers aged 20 weeks were used in this study. Hens distributed randomly four treatments (30 hens each) with three replicates. The supplemented into basal diet at different concentrations as follows; (T1...

Serum levels of T3, T4, and TSH hormones, some elements, and glucose with regard to their involvement for growth retardation in yearling rams were investigated. A total of 70 yearling rams of the Akkaraman breed, 50 of which were classified with a retarded growth, and the remaining 20 were classified as normal, were included in the study. Serum total T3, total T4, and TSH were measured using ch...

This study was to determine the daily fluctuation of serum thyroxine (tT4), free thyroxine (fT4), 3,5,3'-triiodothyronine (T3) concentrations in healthy dogs. Thyroid function of these dogs was evaluated on the basis of results of TSH response test. Samples for the measurement of serum tT4, fT4, and T3 concentrations were obtained at 3- hour intervals from 8 : 00 to 20 : 00. Serum tT4, fT4, and...

OBJECTIVE To investigate the effects of hepatic radiofrequency ablation (RFA) in patients with malignant liver disease with respect to inflammation activation and stress response. MATERIALS AND METHODS In an observational trial, we investigated the physiologic parameters of 17 patients (20 interventions) who underwent percutaneous RFA under general anesthesia after applying total intravenous ...

Three consecutive years of field experiments were carried out to investigate the effect of different root temperatures, induced by the application of mulches on the concentration of sulfur (S) forms (organic-S, total-S and SO4(2-)) and Se in different organs of potato plants (roots, tubers, stems and leaves). Four different plastic covers were used (T1: transparent polyethylene; T2: white polye...
