various biological bone g rafts have been used for osteogenes i s , osteoconduction and even osteoinduction, but due to systemic influences and local factors, the outcome of successful incorporation of a bone graft has not been satisfactory. this study was therefore conducted on 15 clinically healthy adult dogs between 1 to 3 years of age weighing 20 to 30 kg to evaluate the effect of bone ceme...

background patients with thalassemia major and intermedia are susceptible to osteopenia and osteoporosis. the mechanism of osteoporosis in these patients is multifactorial. transfusion related iron overload in endocrine organs leads to impaired growth hormone secretion, diabetes mellitus, hypothyroidism, hypoparathyroidism, lack of sex steroids and vitamin d deficiency that contribute to impair...

Multiple marker sets and models are currently available for assessing pelvic kinematics in gait. Despite the presence of a variety models, there are still debates on their reliability and consistency, and consequently there is no clearly defined standard. Two marker sets were evaluated in this study: the 'Traditional' where markers are placed at the anterior and posterior superior iliac spines ...

BACKGROUND CONTEXT In the prehospital stages of emergency care, cervical collars are (supposedly) used to aid rescuers in maintaining in-line stabilization of the spinal column as patients with potential or actual injuries are shifted onto a spine board to achieve full spinal immobilization. Unfortunately, not a single study has examined the effectiveness of cervical collars to control motion d...

BACKGROUND The north-west coast of Spain was heavily contaminated by the Prestige oil spill, in 2002. Individuals who participated in the clean-up tasks showed increased chromosome damage two years after exposure. Long-term clinical implications of chromosome damage are still unknown. OBJECTIVE To realize a follow-up genotoxic study to detect whether the chromosome damage persisted six years ...

introduction: an investigation of bone, cartilage and fat differentiation potentials of canine bone marrow-derived mesenchymal stem cells. materials and methods: bone marrow aspirates were obtained from 10 canine’s iliac crest under general anesthesia. each sample was separately loaded on lymphodex and centrifuged at 1200 rpm for ten minutes to obtain mononuclear cell fraction. 5×104 cell/cm2 o...

women's health. although calcium deficiency intake is only one of the factors that effects bone fractures, there are many evidences that sufficient calcium have direct effect in bone density and reverse effect upon bone fractures rate. methods: this study is a descriptive cross-sectional type. a sample of 271 female students in tabriz medical sciences university, aged 20-25 years was studied in...

background different clinical and epidemiological studies using dual-energy x-ray absorptiometry have shown an increased prevalence of low bone mineral density in patients with inflammatory bowel diseases.the aim of this study was to assess the correlation between bone density and the disease activity in patients with ulcerative colitis. methods in this cross-sectional study, 52 patients with u...

bone matrix gelatin (bmg) has been used for bone induction intramuscularly and subcutaneously by many investigators since 1965. more recently, some of the researchers have used bmg particles for bone repair and reported various results. in present study for evaluation of bone induction and new bone formation in parital defects, bmg particles were used in five groups of rats. the bmg was prepare...
