In order to determine the nature of afferent fibres contacting thyrotropin-releasing hormone (TRH)-synthesizing neuronal cell bodies in the rat hypothalamic paraventricular nucleus, we used dual immunostaining procedures which employed antibodies to ACTH (to label proopiomelanocortin (POMC) neurons), neuropeptide Y (NPY) and dopamine-beta-hydroxylase (D(More)
The localization of cells which produce estrogen receptors in the rat central nervous system was performed using an in situ hybridization technique. For this, we used a synthetic oligonucleotide probe labeled with 35S complementary to the mRNA coding for a fragment (1-24) of estradiol receptor which is not common to the other steroid receptors so far(More)
Quantitative structure-activity relationships (QSARs) for 35 cinnamamides were studied. By using a genetic algorithm (GA), a group of multiple regression models with high fitness scores was generated. From the statistical analyses of the descriptors used in the evolution procedure, the principal features affecting the anticonvulsant activity were found. The(More)
In order to investigate the possible involvement of corticotropin-releasing factor (CRF) and somatostatin (SRIF) on thyrotropin-releasing hormone (TRH) neuronal cell activity in the rat hypothalamic paraventricular nucleus, we have proceeded to the simultaneous localization of CRF or SRIF and TRH. For this purpose, we used a dual immunostaining procedure(More)
The localization of estrogen receptors in the rat pituitary gland was performed by in situ hybridization. The probe used was a synthetic oligonucleotide probe labelled with 35S complementary to the mRNA coding for a fragment (1-24) of estrogen receptor. Strong labelling was observed in cells of the anterior and intermediate lobes whereas the posterior lobe(More)
Using an antiserum to a synthetic peptide corresponding to the sequence Phe-178-Ser-199 of the precursor of thyrotropin-releasing hormone (pro-TRH), we have studied by immunoelectron microscopy the ultrastructural localization of pro-TRH in the rat hypothalamus. In the paraventricular nucleus neuronal cell bodies, dendrites and axons were labelled. The(More)
Using antisera to two pro-thyrotropin-releasing hormone (pro-TRH)-derived cryptic peptides, we have studies by immunocytochemistry the ultrastructural localization of pro-TRH in the rat raphe nuclei. The same results were obtained with both antisera. Immunostaining was found in cell bodies, dendrites and endings. In cell bodies, the reaction product was(More)
Tracking and monitoring of cells in vivo after transplantation can provide crucial information for stem cell therapy. Magnetic resonance imaging (MRI) combined with contrast agents is believed to be an effective and non-invasive technique for cell tracking in living bodies. However, commercial superparamagnetic iron oxide nanoparticles (SPIONs) applied to(More)
Thyrotropin-releasing hormone prohormone contains five copies of the thyrotropin-releasing hormone progenitor sequence Gln-His-Pro-Gly, each flanked by pairs of basic amino acids and separated by intervening sequences (connecting peptides). Using a perifusion system for rat hypothalamic slices, we have studied the ionic mechanisms underlying the release of(More)
