Functional Interactions Among Thyrotropin-Releasing Hormone (Trh), Prolactin (Prl) and Dopamine (Da) in the Brain
… mechanisms that regulate the in vitro release of thyrotropin-releasing hormone (TRH) from the mediobasal hypothalamus (MBH) and in the actions of prolactin (PRL) on the activity of dopaminergic neurons in the striatum and the MBH. In the present work the spontaneous and induced release of TRH and …

Thyroid hormonal axis as a significant regulator of haemostasis // Тироидната хормонална ос - значим регулатор на хемостазата
… влиянието на хормоните на тироидната ос - TRH (Thyrotropin releasing hormone), TSH (Thyroid stimulating hormone), T3 (Trijodthyroninum) и Т4 (Thyroxin) върху хемостазата у плъхове. Използвани са 1027 бели мъжки плъха, порода Wistar, от които 810 опитни и 217 контролни. Опитните животни бяха …

Transcriptomic Profiling of Hypothalamic Kiss1 Neurons
… but not corticotropin releasing hormone, thyrotropin releasing hormone, oxytocin, or vasopressin receptors. To further understand the molecular and physiological uniqueness of Kiss1ARC and AVPV Kiss1 (Kiss1AVPV) neurons, unbiased transcriptomic profiling was done using RNA-sequencing on …

The evolution of the autoantibody response in Graves’ disease
… stimulating antibodies (TSAbs) activating the thyrotropin receptor (TSHR). Both genetic and environmental factors contribute to pathogenesis and one such factor is the infectious agent, Yersinia enterocolitica. Two high affinity TSAbs, (KSAbl, lgG2t>/K; KSAb2, IgGaa/K), developed from an …

The Role of Escherichia Coli Endotoxins in The Pathogenesis of Lactation Failure in The Sow
… second time. Endotoxin administration suppressed thyrotropin releasing hormone (TRH) (100 (mu)g IV) stimulated PRL release on PP + 2 but not on PP + 6. The results suggested that the suppressive effects of E. coli endotoxins on PRL are partially mediated directly at the adenohypophysis. Experiment …

Evaluation of the effects of clomipramine on the canine hypothalamic-pituitary-thyroid axis
… concentrations were measured on selected days. Thyrotropin-releasing hormone (TRH) response tests were performed concurrently. Repeated measures analysis of variance was applied to test for effects of day of treatment; when significance (p < 0.05) was noted, it was further investigated using …

Effects of Levothyroxine Adminstration and Withdrawal on the Hypothalamic-Pituitary-Thyroid Axis in Euthyroid Dogs
… free thyroxine (fT4) by equilibrium dialysis, thyrotropin (TSH), and 3,5,3'-triiodothyronine (T3) were measured every 4 weeks during supplementation and for 16 weeks after levothyroxine was discontinued. Results: Mean serum T4 and fT4 were significantly higher and TSH was lower in all dogs …

Thyroid hormones and breast cancer-prospective studies on incidence, mortality and prognostic factors
… risk of breast cancer. The association between thyrotropin (TSH) levels and breast cancer risk was studied in 2696 women with173 incident breast cancer cases. The association between TSH and thyroid peroxidase antibodies (TPO-Ab) and breast cancer risk was studied in 676 breastcancer cases and …

Development of Cochlear Nonlinearities in Normal and Tshr Mutant Mice
… point mutation in the gene that encodes the thyrotropin receptor resulting in the loss of its ability to bind thyroid stimulating hormone, a condition that leads to thyroid gland hypoplasia and profound congenital hypothyroidism. The defect is transmitted as an autosomal recessive trait, so …

Aspects of lactation endocrinology: I. lactogenic receptors in bovine mammary tissue at different stages of lactation: II. growth hormone concentrations in Holstein cattle of differing genetic merit
… Holstein bull calves were administered Glc and thyrotropin releasing hormone (TRH) on different days. Plasma GH was greater in selected animals. Plasma Prl was greater in control animals after TRH. In the third experiment, Holstein cows received TRH at 30, 90 and 200 days postpartum (DPP). Net …
