Complementarity of radioautographic and immunohistochemical techniques for localizing neuroreceptors at the light and electron microscopy level BJMBR
Beaudet,A..
To assess relationships between neuropeptide-binding sites and receptor proteins in rat brain, the distribution of radioautographically labeled somatostatin and neurotensin-binding sites was compared to that of immunolabeled sst2A and NTRH receptor subtypes, respectively. By light microscopy, immunoreactive sst2A receptors were either confined to neuronal perikarya and dendrites or diffusely distributed in tissue. By electron microscopy, areas expressing somatodendritic sst2A receptors displayed only low proportions of membrane-associated, as compared to intracellular, receptors. Conversely, regions displaying diffuse sst2A labeling exhibited higher proportions of membrane-associated than intracellular receptors. Furthermore, the former showed only low...

Effect of high energy intake on carcass composition and hypothalamic gene expression in Bos indicus heifers R. Bras. Zootec.
Diniz-Magalhães,Juliane; Mesquita,Lígia Garcia; Carvalho,Marina Vieira de; Machado,Anna Beatriz Escarpellin; Pimentel,José Rodrigo Valim; Prada e Silva,Luis Felipe.
ABSTRACT The objective of this study was to evaluate the effect of high or low energy intake on carcass composition and expression of hypothalamic genes related to the onset of puberty. Twenty-four prepubertal Nellore heifers, 18-20- months-old, with 275.3±18.0 kg body weight (BW), and 4.9±0.2 (1-9 scale) body condition score (BCS) were randomly assigned to two treatments: high-energy diet (HE) and low-energy diet (LE). Heifers were housed in two collective pens and fed diets formulated to promote average daily gain of 0.4 (LE) or 1.2 kg (HE) BW/day. Eight heifers from each treatment were slaughtered after the first corpus luteum detection - considered as age of puberty. The 9-10-11th rib section was taken and prepared for carcass composition analyses....

General principIes and applications ofacupuncture in small animaIs: literature review MV&Z
Hayashi, Ayne Murata; Matera, Julia Maria.
Objective: To present and disclose the technique, equipment, mode of action and main applications of acupuncture in small animals. Data Sources: CAB, MEDLJNE and Web of Science, over the last 20 years, and the collection of the library of the Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo (School of Veterinary Medicine and Animal Science of the University of São Paulo) and of the B/REME - Centro Latino-Americano e do Caribe de Informação em Ciências da Saúde. (Latin American and Caribbean Cemerfor Health Science Information). Data Synthesis: Acupuncture is a treatment modality employing sensor}' stimulation to cause the release of local and distam neuropeptides, once the peripheral and central nervous systems are involved. The...

Mapping and signaling of neural pathways involved in the regulation of hydromineral homeostasis BJMBR
Antunes-Rodrigues,J.; Ruginsk,S.G.; Mecawi,A.S.; Margatho,L.O.; Cruz,J.C.; Vilhena-Franco,T.; Reis,W.L.; Ventura,R.R.; Reis,L.C.; Vivas,L.M.; Elias,L.L.K..
Several forebrain and brainstem neurochemical circuitries interact with peripheral neural and humoral signals to collaboratively maintain both the volume and osmolality of extracellular fluids. Although much progress has been made over the past decades in the understanding of complex mechanisms underlying neuroendocrine control of hydromineral homeostasis, several issues still remain to be clarified. The use of techniques such as molecular biology, neuronal tracing, electrophysiology, immunohistochemistry, and microinfusions has significantly improved our ability to identify neuronal phenotypes and their signals, including those related to neuron-glia interactions. Accordingly, neurons have been shown to produce and release a large number of chemical...

Relative distribution of gastrin-, CCK-8-, NPY- and CGRP- immunoreactive cells in the digestive tract of dorado (Salminus brasiliensis). Repositório Alice
PEREIRA, R. T.; COSTA, L. S.; OLIVEIRA, I. R. C.; ARAUJO, J. da C.; AERTS, M.; VIGLIANO, F. A.; ROSA, P. V..
The endocrine cells (ECs) of the gastrointestinal mucosa form the largest endocrine system in the body, not only in terms of cell numbers but also in terms of the different produced substances. Data describing the association between the relative distributions of the peptide-specific ECs in relation to feeding habits can be useful tools that enable the creation of a general expected pattern of EC distribution. We aimed to investigate the distribution of ECs immunoreactive for the peptides gastrin (GAS), cholecystokinin (CCK-8), neuropeptide Y (NPY), and calcitonin gene-related peptide (CGRP) in different segments of the digestive tract of carnivorous fish dorado (Salminus brasiliensis) by using immunohistochemistry procedures. The distribution of endocrine...
