Corticotropin-releasing factor (CRF) receptor-binding sites have been localized and quantified in the rat central nervous system (CNS) by autoradiography with an iodine-125-labeled analogue of ovine CRF substituted with norleucine and tyrosine at amino acid residues 21 and 32, respectively. High affinity and pharmacologically specific receptor-binding sites for CRF were found in discrete areas ...
Metabolic changes in the brain stem were measured at the time when oxygen deprivation-induced respiratory depression occurred. Eucapnic ventilation with 8% oxygen in vagotomized urethan-anesthetized rats resulted in cessation of respiratory drive, monitored by recording diaphragm electromyographic activity, on average within 11 min (range 5-27 min), presumably via central depressant mechanisms....
The distribution of Met-enkephalin- and substance P-immunoreactive neurons was studied by indirect immunofluorescence in some areas related to pain and analgesia. Met-enkephalin- and substance P-positive cell bodies and nerve terminals were observed in the periaqueductal central gray, the nucleus raphe magnus, the marginal layers and substantia gelatinosa of the spinal trigeminal nucleus, and t...
Mormyrid fish produce a diverse range of electric signals that are under the control of a central electromotor network. The anatomical organization of this network was delineated by injecting biotinylated compounds into neurophysiologically identified nuclei. Previous work using retrograde labeling with horseradish peroxidase indicated that the medullary command nucleus (CN) receives inputs fro...
The G protein-coupled receptor Mas was recently described as an angiotensin-(1-7) [ANG-(1-7)] receptor. In the present study we evaluated the anatomical localization of Mas using immunofluorescence in the central nervous system of adult male Wistar rats. An abundant labeling was found in the hippocampus, amigdala, anterodorsal thalamic nucleus, cortex, and hypoglossal nucleus. More importantly,...
Background: Thyroid carcinoma is the most frequent malignant tumor of the endocrine system in human body and accounts for nearly 1% of all cancers. Medullary thyroid carcinoma is the third frequent of thyroid cancer and accounts about 5-8% of thyroid cancer. Osteocalcin, known as a Bone Gamma-carboxyglutamic Acid-containing Protein (BGLAP), is the most non collagenous protein. Retinol binding p...
of nociceptive cholinergic afferent type C neurons of the trigeminal nerve that relay to the ventromedial spinal trigeminal tract and the adjacent pontine-medullary reticular formation to reach the sneeze-evoking center in the rostral medulla initiates the nasal phase. The respiratory phase begins once inspiratory and expiratory neurons have been recruited, consisting of eye closing, deep inspi...
