The effect of traumatic dental occlusion on the degradation of periodontal bone in rats
(2016-11-01)
Context: A better understanding of the relation between traumatic dental occlusion and periodontal changes is needed. Aims: This study aimed to evaluate the pattern of osteoclastic activity in the periodontal bone in front ...
In vitro and in vivo assessment of CaP materials for bone regenerative therapy. The role of multinucleated giant cells/osteoclasts in bone regeneration
(2019-01-01)
In this work, bone formation/remodeling/maturation was correlated with the presence of multinucleated giant cells (MGCs)/osteoclasts (tartrate-resistant acid phosphatase [TRAP]-positive cells) on the surface of beta-tricalcium ...
In vitro biomechanical evaluation of sagittal split osteotomy fixation with a specifically designed miniplate
(2013-03-01)
Recent studies have evaluated many methods of internal fixation for sagittal split ramus osteotomy (SSRO), aiming to increase stability of the bone segments while minimizing condylar displacement. The purpose of this study ...

Magnesium deficiency results in an increased formation of osteoclasts
(2013-03-19)
Magnesium (Mg2+) deficiency is a frequently occurring disorder that leads to loss of bone mass, abnormal bone growth and skeletal weakness. It is not clear whether Mg2+ deficiency affects the formation and/or activity of ...

Characterization of the pyrethroid resistance mechanisms in a Blattella germanica (Dictyoptera: Blattellidae) strain from Buenos Aires (Argentina)
(Cambridge University Press, 2021-07)
The use of chemical insecticides is the main control method for Blattella germanica worldwide. The prolonged and frequent use of insecticides produced the selection of insecticide-resistant individuals. The German cockroach ...
Effect of pre-treatment of strength training and raloxifene in periestropause on bone healing
(2020-05-01)
Background: There is evidence that strength training (ST) and raloxifene (Ral) treatment during periestropause promotes better bone quality. We wanted to determine whether the skeletal benefits of ST or Ral treatment, ...
Effect of Growth Hormone (GH) and Resistance Training on the Collagen Properties of Femoral Bone Tissue
(Soc Chilena Anatomia, 2019-12-01)
The indiscriminate use of anabolic steroids in gyms has been growing in a generalized way, among which, the most common is growth hormone (GH). In the short term GH may potentiate muscle growth, especially when taken in ...
Differences in the Cortical Structure of the Whole Fibula and Tibia Between Long-Distance Runners and Untrained Controls: Toward a Wider Conception of the Biomechanical Regulation of Cortical Bone Structure
(Frontiers Media, 2019-11)
The cortical structure of human fibula varies widely throughout the bone suggesting a more selective adaptation to different mechanical environments with respect to the adjacent tibia. To test this hypothesis, serial-pQCT ...
