13. Real-time ultrasound to predict rabbit carcass composition and volume of longissimus dorsi muscle
Real-time ultrasonography (RTU) was used to measure the longissimus dorsi muscle (LM) volume in vivo and to predict the carcass composition of rabbits. For this, 63 New Zealand White × Californian rabbits with 2093±63 g live weight were used. Animals were scanned between the 6th and 7th lumbar vertebrae using an RTU equipment with a 7.5 MHz probe. Measurem

14. Diretrizes para prevenção e tratamento da osteoporose induzida por glicocorticoide
Os glicocorticoides (GC) são prescritos por praticamente todas as especialidades médicas, e cerca de 0,5% da população geral do Reino Unido utiliza esses medicamentos. Com o aumento da sobrevida dos pacientes com doenças reumatológicas, a morbidade secundária ao uso dessa medicação representa um aspecto importante que deve ser considerado no manejo

15. Abdominal adiposity, insulin and bone quality in young male rats fed a high-fat diet containing soybean or canola oil
OBJECTIVES: A low ratio of omega-6/omega-3 polyunsaturated fatty acids is associated with healthy bone properties. However, fatty diets can induce obesity. Our objective was to evaluate intra-abdominal adiposity, insulin, and bone growth in rats fed a high-fat diet containing low ratios of omega-6/omega-3 provided in canola oil. METHODS: After weaning, rats

16. Estudo do efeito da cefazolina sobre enxerto de biocomposto para artrodese de coluna lombar em coelhos
The BMPs, the inductive proteins of bone growth since the beginning of their use have been evaluated in different experimental models aiming to determine their efficacy. We know that some substances can interfere positively or negatively when used in a systemic way or places associated with the BMP. Objective: this study objective to evaluate the possible in

17. Protocolo de fotogrametria computadorizada na quantificacao angular da escoliose
The scoliosis is a three-dimensional deformation of the spine. It is a serious disease that can compromise vital organs like heart and lungs, in addition to influence the aesthetic and quality of life. His progression is generally associated with growth peak, getting in that case, the name of the adolescent idiopathic scoliosis (AIS). Thus, the pubertal peri

18. Análise fotoelástica de modelo de vértebra sob influência de parafuso pedicular / Photoelastic analysis of a vertebra model under the pedicular screw influence
O sistema de fixação vertebral utilizando o parafuso pedicular é um dos métodos mais eficientes no tratamento de patologias da coluna vertebral. Quando o parafuso estiver submetido à força de arrancamento, ele gera tensões ao redor, principalmente próximo do canal medular, situação que pode ser analisada pela técnica da fotoelasticidade. O objetiv

19. Efeito do óxido nítrico sobre fêmures e vértebras lombares de ratos orquiectomizados.
Osteoporosis is attributed to an imbalance between bone formation and resorption, followed by bone mass loss and microarchitectural deterioration, leading to increased bone fragility and fracture risk. Nitric oxide (NO) is a signaling molecule with important regulatory effects on bone cell function. Nitric oxide donor nitroglycerin has been reported to allev

20. Evaluation of vertebral bodies and intervertebral discs participation in the lumbar lordosis / Avaliação da participação dos corpos vertebrais e discos intervertebrais na composição da lordose lombar
The vertebral bodies and intervertebral discs participation in lumbar lordosis and their contribution between lumbar curves of different size were studied. 350 lumbar spine radiographs of asymptomatic adults (143 men and 207 women, average age 29 years) were evaluated. Lumbosacral (L1S1) and lumbolumbar (L1L5) curves and the angular inclination of each verte

21. Relationship between the Porcine Stress Syndrome gene and carcass and performance traits in F2 pigs resulting from divergent crosses
The PSS genotypes of 596 F2 pigs produced by initial mating of Brazilian native boars commercial sows and were characterized by PCR-RFLP and their carcass and performance traits were evaluated. Among the 596 animals analyzed, 493 (82.72%) were characterized as NN and 103 (17.28%) as Nn. With respect to carcass traits, Nn animals presented higher (p < 0.05) r

22. Densidade mineral Ãssea em adolescentes femininas: relaÃÃo entre sobrepeso e atividade fÃsica diÃria
The aim of this study was to examine the possible correlations between bone mineral density (BMD), the overweight and the levels of physical activity in female adolescents aged 14-17 years. Daily physical activity level was measured by questionnaire in 321 adolescents. Voluntarily, 70 of these adolescents, participation of the anthropometric measurements of

23. Densidade mineral ossea em pacientes com lupus eritematoso sistemico e sua relação com niveis estrogenos
The objectives of this study were: 1) to evaluate bone mineral density ( BMD ) in premenopausal patients with systemic lupus erythematosus ( SLE ); 2) to determine the role of corticosteroids and citotoxic drugs and 3) to assess estrogen effect on BMD in SLE. BMD was measured by dual energy x-ray absorptiometry at lumbar vertebrae ( L2-L4 ) and at femoral ne

24. The compressive strength of lumbar vertebrae.
Values for the compressive breaking load of lumbar vertebrae at physiological strain rates show enormous scatter across the population, ranging from 0.8 kN to nearly 16 kN. Increase in strength was found at faster strain rates, but differences in compressive strength between upper and lower lumbar vertebrae were not significant. Hydraulic strengthening does
