Rapid maxillary expansion causes neuronal activation in brain structures of rats
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
A correlation between pain sensation and neuronal c-fos expression has been analyzed following experimental rapid maxillar expansion (RME). Adult male Wistar rats were anaesthetized and divided into three groups: animals ...
Effects of short-term acetaminophen and celecoxib treatment on orthodontic tooth movement and neuronal activation in rat
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Non-steroidal anti-inflammatory drugs (NSAIDs) have been used for pain relief in orthodontics, but clinical studies reported that they may reduce tooth movement (TM). By other side, TM seems to activate brain structures ...
Ultrastructural aspects of Callithrix penicillata lingual papillae
(WILEY-BLACKWELLMALDEN, 2012)
Callithrix penicillata belongs to the family Callitrichidae, Callithrix genus. They are basically insectivorous, but they consume fruits. The mucosa of the tongue is composed of some papillary types, revealing different ...
Fluorescent indication that nitric oxide formation in NTS neurons is modulated by glutamate and GABA
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
Nitric oxide (NO) in NTS plays an important role in regulating autonomic function to the cardiovascular system. Using the fluorescent dye DAF-2 DA, we evaluated the NO concentration in NTS. Brainstem slices of rats were ...
Effects of incubation temperature on muscle morphology and growth in the pacu (Piaractus mesopotamicus)
(Elsevier B.V., 2004-08-02)
This study describes the influence of incubation temperature during initial development phase on the morphology and muscle growth characteristics in the pacu (Piaractus mesopotamicus). Pacu eggs were incubated at 25, 27, ...

(2013-04-01)
Zara, F.J., Gaeta, H.H., Costa, T.M., Toyama, M.H. and Caetano, F.H. 2011. The ovarian cycle histochemistry and its relationship with hepatopancreas weight in the blue crab Callinectes danae (Crustacea: Portunidae). -Acta ...
Changes in tri-methylation profile of lysines 4 and 27 of histone H3 in bovine blastocysts after cryopreservation
(Elsevier B. V., 2015)
Pregnancy rates from cryopreserved embryos remain lower than non-cryopreserved counterparts, even though these embryos appear morphologically normal. How epigenetic events, such as histone modifications, are affected by ...
Histomorfometria do útero de gatas submetidas à ovariosalpingohisterectomia
(2012)
Histomorphometric data were obtained from cats uterine horns: either nulliparous (n = 6), primiparous (n = 6), multiparous (n = 6) and treated with contraceptive (n = 6). The material was collected after surgery, fixed in ...
Expression of fibroblast growth factor 22 (FGF22) and its receptor, FGFR1B, during development and regression of bovine corpus luteum
(Elsevier B.V., 2019-02-01)
The aim of this study was to determine the expression of fibroblast growth factor 22 (FGF22) in the bovine corpus luteum (CL) and to investigate the effects of in vivo total or partial cloprostenol-induced luteolysis on ...
A presença da proteína nuclear específica neuronal (NeuN) no sistema de temporização circadiano do macaco capuchinho (Cebus apella)
(2010-12-01)
Background and objective: The circadian timing system (CTS) is composed of a group of specialized neuronal structures that establish a temporal organization of physiological and behavioral processes within precise patterns. ...
