1. Two and three-dimensional morphometric analysis of trabecular bone using X-ray microtomography (µCT)
INTRODUCTION: Trabecular bones have a porous microstructure and can be modeled as linear elastic solids, heterogeneous and anisotropic. In the literature, few investigations have compared the two- dimensional (2D) and three-dimensional (3D) morphometric analyses of cancellous bone. METHODS: In this investigation eighteen cylindrical samples of cancellous bon

2. Stretch-induced nerve injury: a proposed technique for the study of nerve regeneration and evaluation of the influence of gabapentin on this model
The rat models currently employed for studies of nerve regeneration present distinct disadvantages. We propose a new technique of stretch-induced nerve injury, used here to evaluate the influence of gabapentin (GBP) on nerve regeneration. Male Wistar rats (300 g; n=36) underwent surgery and exposure of the median nerve in the right forelimbs, either with or

3. Investigação da microarquitetura óssea através de microtomografia 3D / Investigation of bone microarchitecture using 3D microtomography
X-Ray Computed Microtomography (uCT) is a nondestructive technique used to study the internal structure of bones with a spatial resolution of the order of microns. In this study, six pairs of bone samples (femur mouse) were studied by uCT. The tests were conducted in the absence or presence of aluminum filters (thickness of 0.25, 0.50 and 0.75 mm), using thr

4. Avaliação neurológica e histológica de lesão compressiva da medula espinhal de ratos wistar, tratados com células-tronco mesenquimais / Mesenchymal stem cells therapy for spinal cord injury in Wistar rats: neurological recovery and histological changes
Effective treatment for spinal cord injury remains subject of several studies. Cell therapy is considered an option promising for lesions of the central nervous system, particularly stem cells after experimental animal models showed the transplantation of bone marrow-derived cells results in amelioration of the functional deficit in various neurological dise

5. Beneficial effects of treadmill training in experimental diabetic nerve regeneration
OBJECTIVES: We investigated the effects of treadmill training (10 weeks) on hindlimb motor function and nerve morphometric parameters in diabetic rats submitted to sciatic nerve crush. MATERIALS AND METHOD: Wistar rats (n = 64) were divided into the following groups: non-diabetic; trained non-diabetic; non-diabetic with sciatic nerve crush; trained non-diabe

6. Repercussões do destreinamento físico sobre o metabolismo e a celularidade do tecido adiposo branco periepididimal de ratos. / Physical detraining repercussions on metabolism and cellularity of white adipose tissue periepididymal in rats.
All adaptations acquired through physical training are reversible during inactivity. Significant reductions in maximal oxygen uptake (VO2Max) are observed within two-four weeks of detraining. Conversely, the consequences of detraining on adipose tissue are poorly known. The objective was to investigate the physical detraining effects on metabolism and cellul

7. Influence of protaper finishing files and sodium hypochlorite on cleaning and shaping of mandibuldar central incisors - a histological analysis
OBJECTIVE: This study investigated the influence of the last apical instrument of the ProTaper system with and without 2.5% sodium hypochlorite for cleaning mandibular central incisors. MATERIAL AND METHODS: Thirty two mandibular central incisors were divided into six study groups: Group I - F1 instrument with 2.5% sodium hypochlorite; Group II - F1 and F2 w

8. Análise morfométrica 2D e 3D de amostras de osso trabecular utilizando microtomografia tridimensional por raio-X / 2D and 3D morphometric analysis of trabecular bone using X-ray tridimensional microtomography (müCT)
Trebecular bones have a porous microstructure and can be modeled as a linear elastic solid, heterogenous and anisotropic. The x-ray tridimensional microtomography (müCT) has been worldwide used for the assessment of trabecular bone in investigations related to bone quality and aimed to the diagnostic of bone metabolic diseases such as osteoporosis. In the l

9. Diversity among populations goats based on morphometric markers / Diversidade genética entre populações caprinas com base em marcadores morfométricos
The goats were introduced in Brazil by the Portuguese colonizers. Today it is difficult to accurately identify the origin of the Brazilian domestic animals and it is unknown the entire extent of its diversity. The conservation and breeding of domestic animals depend on diversity in the species concerned. Theobjectives of this study were 1. compare different

10. Influencia do fator de transcrição MEF2C na hipertrofia miocardica induzida por sobrecarga pressorica em camundongos / Influence of the transcription factor MEF2 in cardiac hypertrophy induced by overload pressure in mice
Heart diseases are frequently associated with myocardial hypertrophy. Mechanical stimuli can trigger hypertrophic growth as well as degeneration and death of the cardiac myocytes. The MEF2C family of transcription factors plays a role in the process of myocardial hypertrophy. It is composed by 4 members, MEF2A, B, C and D, and the MEF2C is the main transcrip

11. Dendritic thickness: a morphometric parameter to classify mouse retinal ganglion cells
To study the dendritic morphology of retinal ganglion cells in wild-type mice we intracellularly injected these cells with Lucifer yellow in an in vitro preparation of the retina. Subsequently, quantified values of dendritic thickness, number of branching points and level of stratification of 73 Lucifer yellow-filled ganglion cells were analyzed by statistic

12. Reproductive Biology, Population Dynamics and Risk of Extinction of Aegla strinatii Türkay, 1972 (Crustacea, Decapoda, Aeglidae) / Biologia reprodutiva, estrutura e dinâmica populacional e avaliação do grau de risco de extinção de Aegla strinatii Türkay, 1972 (Crustacea, Decapoda, Aeglidae)
This study aims to contribute for preservation of the only known population of Aegla strinatii and to reinforce the necessity to preserve the areas where this species occur. Therefore, monthly collections were realized during a two year period at Jacupiranga State Park which is considered to be the second largest conservation unit of São Paulo State. The sp
