1. Effect of different vitamin D3 metabolites on intestinal calcium homeostasis-related gene expression in broiler chickens
ABSTRACT The purpose of this study was to investigate the effects of vitamin D3 metabolites 1α-hydroxycholecalciferol (1α(OH)D3), 25-hydroxycholecalciferol (25(OH)2D3), and 1,25-dihydroxycholecalciferol (1,25(OH)2D3) on growth performance, bone quality, and intestinal calcium homeostasis-related gene expression in broiler chickens. One-day-old broilers wer

2. Estudo in vitro do potencial de diferenciação das células tronco imaturas da polpa dentária humana em neurônios retinais. / Study of in vitro differentiation of human immature dental pulp stem cells into retinal neurons cells.
A retina é composta por células neuronais especializadas, que quando danificadas são incapazes de se regenerar. CTIPD são uma promissória fonte para substituir o tecido lesado pois são capazes de se diferenciar em quase todos os tipos celulares. O objetivo do estudo é avaliar o potencial de diferenciação das CTIPD em neurônios retinais. As CTIPD fo

3. Caracterização citoarquitetônica, neuroquímica e de aferência óptica do complexo parabraquial do sagui (Callithrix jacchus)
The parabrachial complex (PB) is an area of the brainstem responsible for the processing and transmission of essential physiologic information for the survival of the organisms. This region is subdivided in approximately nine subregions, considering morphology, cytoarchitectural and functional characteristic. Its neurons have an extensive network of connecti

4. Estudo da imunorreatividade das proteínas ligantes de cálcio na neuroquímica da medula espinal de ratos submetidos à atividade física espotânea na roda de corrida. / Study of the imunoreativite of ligantes calcium proteins in the neurochemistry of the espinal marrow of submitted rats the spontaneous physical activity in the race wheel
Actions of the physical activity in the neurochemistry focuzing calcium-bindin proteins and the activation of the glial cells in the spinal cord of the rat were investigated with imunohistochemistry over. Male wistar adult rats were divided in two groups: trained, which animals exercised in the wheel running for 4 and 14 nigths; and sedentary, which animals

5. Centros rombencefálicos de processamento auditivo do sagui (Callithrix jacchus): uma análise citoarquitetônica e neuroquímica
The auditory system is composed by a set of relays from the outer ear to the cerebral cortex. In mammals, the central auditory system is composed by cochlear nuclei, superior olivary complex, inferior colliculus and medial geniculate body. In this study, the auditory rombencephalic centers, the cochlear nuclear complex and the superior olivary complex were e

6. Immunohistochemical characterization of the chick marginal retina
The retina is a highly differentiated tissue with a complex layered structure that has been extensively characterized. However, most of the previous studies focused on the histology of the central retina while little is known about the cellular composition, organization and function of the marginal retina. Recent research has identified a subpopulation of mu

7. Morphoquantitative study of the ileum enteric nervous system immunoreactives neurons to P2X2 receptor, calbindin, calretinin, choline acetyltransferase and nitric oxide sintase of the animals submitted to undernutrition and refeeding. / Estudo morfoquantitativo de neurônios entéricos imunorreativos ao receptor P2X2, a calbindina, a calretinina, a colina acetil transferase e ao óxido nítrico sintase do íleo de animais submetidos à desnutrição e a renutrição protéica.
Foi descrita a presença do receptor P2X2 no sistema nervoso entérico e foi constatado que a desnutrição afeta os neurônios mioentéricos. Este projeto analisou os neurônios dos plexos mioentérico (PM) e submucoso (PS) imunorreativos ao receptor P2X2(ir), calbindina (Calb-ir), calretinina (Calr-ir), colina acetil transferase (ChAT-ir) e ao óxido nítr

8. Antiproliferative effects of 1,25-dihydroxyvitamin D3 on breast cells: a mini review
The hormone 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3), the active form of vitamin D3, is an important regulator of calcium homeostasis, exerts antiproliferative effects on various cell systems and can induce differentiation in some kinds of hematopoietic cells. These effects are triggered by its receptor, vitamin D receptor (VDR), a phosphoprotein member of th

9. Presumptive Renshaw cells contain decreased calbindin during recovery from sciatic nerve lesions.
A subpopulation of calbindin-immunoreactive neurons in lamina VII of the spinal cord has been identified by its location as Renshaw cells, the anatomical substrate for recurrent inhibition. The expression of calbindin (28 kDa) in these calbindin-containing rat ventral horn interneurons was studied with immunocytochemistry after sciatic nerve injuries. One we

10. Transfection and overexpression of the calcium binding protein calbindin-D28k results in a stimulatory effect on insulin synthesis in a rat β cell line (RIN 1046-38)
Calbindin-D28k, a calcium binding protein that is thought to act as a facilitator of calcium diffusion in intestine and kidney, is known to be regulated by vitamin D in these tissues. Calbindin-D28k is also present in pancreatic β cells, but its function in these cells is not known. To determine a role for calbindin-D28k in the β cell, rat calbindin-D28k w

11. Expression of calbindin-D28K in motoneuron hybrid cells after retroviral infection with calbindin-D28K cDNA prevents amyotrophic lateral sclerosis IgG-mediated cytotoxicity.
Calbindin-D28K and/or parvalbumin appear to influence the selective vulnerability of motoneurons in amyotrophic lateral sclerosis (ALS). Their immunoreactivity is undetectable in motoneurons readily damaged in human ALS, and in differentiated motoneuron hybrid cells [ventral spinal cord (VSC 4.1 cells)] that undergo calcium-dependent apoptotic cell death in

12. Gestational changes in calbindin-D9k in rat uterus, yolk sac, and placenta: implications for maternal-fetal calcium transport and uterine muscle function.
Calbindin-D9k was quantified and its cellular location was defined in uterus, yolk sac, and placenta. In late gestation (days 17 to term) coordinated induction of calbindin-D9k was seen in uterine epithelial lining cells and juxtaposed yolk sac visceral epithelium as well as the intraplacental yolk sac epithelium. The induction of calbindin-D9k in these cell
