1. Histomorphometric analysis of the temporal bone after change of direction of force vector of mandible: an experimental study in rabbits
OBJECTIVES: The present study aimed at performing a histological evaluation of the response of temporal bone tissue to a change of direction of the force vector of the mandible in relation to the base of the skull. MATERIAL AND METHODS: Adult rabbits were assigned into four groups with two control and four experimental animals in each group. experimental ani

2. Diffuse Iris Melanoma in a Cat
Background: Diffuse iris melanoma is rare, although is the most common primary intraocular neoplasm in cats, and is an unusual variant of anterior uveal melanoma. This neoplasm is malignant with high potential methastazed. Affects olders cats without breed or sex predisposition. The diagnosis can be made with fine needle aspiration cytology of anterior segme

3. Análise do gene AIP na acromegalia familial isolada / Analysis of the AIP gene in familial isolated acromegaly
Acromegaly is a rare disfigurating and insidious disease characterized by enlargement of hands, feet and skull bones due to excess of growth hormone (GH) secreted by a pituitary tumor (somatotropinoma). The majority of the cases with acromegaly is sporadic, however it may occur in association with inherited disorders as Multiple Endocrine Neoplasia type 1 (M

4. Ontogenia craniana comparada de Arctocephalus australis, Callorhinus ursinus e Otaria byronia (Otariidae: Pinnipedia)
The search for mechanisms that can generate major morphological changes has led to the study of ontogeny, in part because some kinds of modifications of ontogenies seem an excelent way to generate major phenotypic change. We focus here on Arctocephlaus australis, Callorhinus ursinus and Otaria byronia with the aim of contributing to the understanding of the

5. Cefalostato virtual-posicionamento inicial para a padronização na marcação de pontos craniométricos em imagens obtidas por tomografia computadorizada, para uso em cefalometria / The Virtual Cephalostat - the preliminar adjustment for standardization of skull orientation in landmarks localization using CT in cephalometric analyses
Objective: The development of new technology in dental diagnosis by cone beam CT (CBCT) image, made possible and accessible the realization of cephalometric evaluation through volumetric reconstructions of the skull. Scientific parameters with evidence-based are needed to implement its use. Some parameters used in conventional cephalometry (2D) maybe need to

6. Reparo Ãsseo com a utilizaÃÃo de cÃlulas tronco em ratos submetidos à desnutriÃÃo neonatal
Malnutrition is a public health problem characterized by low intake of essential nutrients for growth and development of the body. Researches involving malnutrition and its consequences in adult life shows that it is capable to change the metabolic programming that impact throughout life. However, little is known about the sequels involving adult stem cells

7. The relationship of otitis media with effusion to the craniofacial growth and occlusal features / Relação da otite média secretora com o crescimento craniofacial e as características oclusais
The aim of this study was to evaluate the craniofacial growth/morphology and dental occlusion in 100 patients (male and female) from 4 to 10 years old and tonsils and adenoid enlargement. There were two groups: with and without otitis media with effusion (OME). We used the cephalometric analyses and dental casts. It was not observed significant differences b

8. Estudos moleculares de craniossinostoses com enfase na mutação Q289P do gene FGFR2 / Molecular of craniosynostosis and the mutation Q289P in the FGFR2 gene
The FGFRs family is involved in the molecular pathway which plays a role in modulation of the craniofacial and members development in humans. Mutations in genes FGFR1, FGFR2 and FGFR3 have been associated to different phenotypes presenting craniosynostosis and other bone diseases. The FGFR2 gene codifies a fibroblast growth factor receptor. The mutation Q289

9. Relationship between cranial and mandibular growth and the stages of maturation of the cervical vertebrae
Quantification of the expectation of craniofacial growth during the pubertal growth spurt (PGS) is helpful in orthodontic diagnosis and treatment planning. Thus, this study investigated whether the stages of the vertebral maturation index (VMI) would be valid for estimating cranial and mandibular growth during the initial stages of PGS, testing the null hypo

10. Avaliação do crescimento craniofacial e das extremidades de pacientes com deficiência de hormônio de crescimento ou síndrome de Turner em tratamento prolongado com hormônio de crescimento / Craniofacial and extremities growth evaluation of patients with GH deficiency or Turner syndrome during long-term growth hormone treatment
INTRODUÇÃO: Pacientes com deficiência de GH e síndrome de Turner, associados a baixa estatura, são beneficiados com o tratamento com GH. Há controvérsias sobre a atuação deletéria do GH no crescimento craniofacial, porém a maioria dos trabalhos é retrospectiva. Nosso objetivo foi realizar estudo prospectivo para avaliar o crescimento craniofacial

11. DesnutriÃÃo experimental e treinamento fÃsico: estudo de parÃmetros murinomÃtricos de ratas gestantes e dos conceptos
The period of conception to the birth is characterized by fast growth, replication, cellular differentiation, and maturation of organs and systems. A stimulus or insult when applied at a critical or sensitive period of development results in a long-term effects of on the structure or function of the organism. The present study had as objective establishes a

12. NutriÃÃo, hipertiroidismo precoce e desenvolvimento cerebral: estudo em ratos recÃm-desmamados
It is known that early alterations of thyroid function interferes with cerebral development and physiology. In this work we investigated the effects of early treatment with thyroxin (T4) on the propagation of cortical spreading depression (SD) in weaned rats. Female adult Wistar rats fed a lab chow diet (CD; 23% protein) were treated with T4 (20ug/kg/day, si
