in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test...
Buckling restrained braced frames (BRBFs) for seismic load resistance have been widely used in recent years. One of the key requirements for a buckling restrained brace is to sustain large plastic deformations under severe ground motions. The core of a buckling restrained brace is prone to fatigue fracture under cyclic loading. The earthquake induced fracture type of the core plate in a bucklin...
It is a long standing question as which genes define the characteristic facial features among different ethnic groups. In this study, we use Uyghurs, an ancient admixed population to query the genetic bases why Europeans and Han Chinese look different. Facial trait variations were analyzed based on high dense 3D facial images; numerous biometric spaces were examined for divergent facial feature...

Classic treatment of galeazzi fracture-dislocation in adults is open radius reduction o radius fracture and closed reduction of distal radioulnar Joint. In this two cases, fracture occurred in distal third radius and treated by closed method. Reduction was anatomic and postoperative and late results was good.
Background and Aims: Endodontically treated teeth are prone to fracture because they loose a big amount of their structure. The treatment plan of those teeth is completed when they are rehabilitated with a strong and functional restoration. The purpose of this study was to evaluate the fracture resistance of endodontically treated teeth restored with amalgam cuspal coverage in comparison with o...
Background & Aims: Osteoporosis is the most common metabolic bone disease .In the recent decades due to the increase of population age, the prevalence of osteoporosis has been increased. The most important complication of osteoporosis is bone fracture, especially in the hip. The aim of this study was to evaluate the prevalence of osteoporosis, its mortality rate and direct treatment costs in...
A 3-year-old Arabian colt was presented for a major gingiva wound at the right rostral part of mandible. After clinical assessments, rostral mandibular fracture was determined. Stabilization of fractured region was achieved via cerclage wire application under general anesthesia. Fixation wires were left in place for 6 weeks. A 3 -month follow up revealed complete fracture healing. The purpose o...
Background : Primary Hyperoxaluria is one of the causes of multiple kidney stones and renal failure in low age groups. Changes in structure of bone in these patients included two types: bone oxalosis and renal osteodystrophia. Case report : The patient was a child aged 10 years old under dialysis due to renal failure. He had a fracture of femoral neck and two times subtrochanteric fracture....
introduction the debate regarding the description on classification and nomenclature of the injury which includes olecranon fracture associated with radial neck fractures in children is ongoing. we report two pediatric cases that could not be classified in a monteggia-equivalents system and were treated with open reduction and k-wire fixation. the aim of this study was to perform a systematic r...
