Bone microarchitecture, bone mineral density (BMD), and bone strength are affected positively by impact activities such as running; however, there are discrepancies in the magnitude of these effects. These inconsistencies are mainly a result of varying training protocols, analysis techniques, and whether or not the skeletal sites measured are weight bearing. This study's purpose was to determin...

The maintenance of bone strength has been an important issue in the debate over cage use for laying hens. Bone strength depends on adequate mechanical load and cages restrict movement. Four laying crosses (Lohmann White, Lohmann Brown, H&N White, and Rhode Island Red × Barred Plymouth Rock cross hens) were housed in conventional cages or in floor pens equipped with perches and nest boxes to mea...

In the present population-based study including 70-year-old men and women, total dairy product intake was associated with a weak positive association with tibia trabecular and cortical cross-sectional areas. PURPOSE Milk consumption has recently been suggested to increase fracture risk. Therefore, we aimed to investigate associations between dairy product consumption and peripheral bone prope...

Botulism is a generalized paralyzing disease caused by the toxin of Clostridium botulinum (BTX). The toxin acts 3-4 days after injection by blocking the release of acetylcholine to the muscle. Six Wistar rats received a 2-U injection of BTX in the right quadriceps. Six rats were similarly injected with saline and were used as control. Paralysis of the quadriceps was obtained 4-5 days after the ...

Bone damage removal and callus formation in response to fatigue loading are essential to prevent fractures. Periostin (Postn) is a matricellular protein that mediates adaptive response of cortical bone to loading. Whether and how periostin influences damage and the injury response to fatigue remains unknown. We investigated the skeletal response of Postn(-/-) and Postn(+/+) mice after fatigue s...

conclusions with the average 89 months follow-up, no recurrence of the diseases was found in the patients. it seems that using of cement and oral anti-parasitic, after extensive resection of the lesion is a proper treatment of bone hydatid disease. introduction bone is an uncommon site of involvement in hydatid disease; with the prevalence of 0.5-2% among bone lesions. case presentation in this...

A group of 37 spinal cord injured (SCI) patients underwent bone density measurements at the distal and proximal end of the tibia by a special computed tomography scanner, the OsteoQuant. Fifteen of these patients had follow-up measurements while enrolled in a lower-limb exercise training program with functional electrical stimulation (FES). The pre-exercise measurements revealed a strong correl...

background: appropriate endurance exercise can change bone mass density and strength of weight-bearing bones in both animals and humans, but its effects on the microstructure are not known. this study aimed to determine skeletal changes induced by the treadmill running endurance in ovariectomized adult mice. methods: twenty-seven adult female rats were divided into experimental and control grou...

a 48-year-old man referred with pain and swelling at the upper and middle third of left tibia with a history of previous os­seous hydatid disease three years ago. despite surgical procedure which was performed in this case, recurrence was ob­served and repeated exploration with wide resection and oral medical therapy were recommended. bone hydatid cyst is an uncommon disease with difficult resp...

UNLABELLED Glucocorticoid (GC) treatment is the main cause of secondary osteoporosis. There are some controversies about the relationships between alveolar bone loss and bone loss at the appendicular and axial skeleton. OBJECTIVE To assess, in parallel, the effects of GCs on alveolar bone and on the tibia in a mice model. METHODS Five-month-old male Swiss-Webster mice were randomized into t...
