Introduction: The purpose of the present study was to evaluate the effect of prednisolone on the sensitivity of bone scanning to detect the simulated closed fracture in the rat tibia.  Methods: A total number of forty eight adult, male NMRI rats randomly assigned into two parts, one part for 4 and other for 8 weeks experiments. Each part has been divided into four groups, one group not receivi...

Hydraulic fracturing and matrix stimulation are two major methods of the reservoir stimulation. Hydraulic fracturing, which is the newest technique and technically more complex, is very useful in low permeability reservoirs. Although it has been used widely in hydrocarbon production wells, it is a new method in Iran. In this paper, the effect of sufficient barrier layers on hydraulic fracturing...

  Background: Previous anatomic and radiological studies have described the relationship of the clavicle to major neurovascular structures in healthy subjects. We were curious about this relationship in patients with a clavicle fracture and if it is different from non-fractured clavicles.   Methods: We retrospectively identified all patients with a clavicle fracture between July 2001 and Octobe...

numerical methods such as boundary element and finite element methods are widely used for the stress analysis in solid mechanics. this study presents boundary element method based on the displacement discontinuity formulation to solve general problems of interaction between hydraulic fracturing and discontinuities. the crack tip element and a higher order boundary displacement collocation techn...

hydraulic fracturing in the fractured reservoirs plays a significant impact on the production rate. in this study, the hydrostatic condition is taken into account, the hydraulic fracturing operation was applied in every direction usinga written distinct element code. in each direction the hydraulic fracture is applied with different lengths and in each level the amount of production is predicte...

because of the prevalent occurrence of pelvic fracture and its death consequences the present research was conducted to determine epidemiological of pelvic fracture of patients who referred to taleqani hospital of kermanshah during 2002-2008. in a retrospective study, 54 patients were studied employing to patient medical file. 17 patients were women, 37of cases were men. range of age was betwee...

root fracture injuries affect up to 7% of permanent teeth. this type of injury is rarely seen in teeth with open apices and depending on the fracture site, the prognosis is good. this case report describes a horizontal intra-alveolar root fracture in the middle third of a maxillary central incisor associated with an extrusive luxation of the coronal segment and its treatment in a 6-year-old gir...

STUDY DESIGN Retrospective study. PURPOSE To determine the prevalence of high risk patient with osteopenia requiring pharmacologic treatment and investigate the difference of 10-year fracture probability whether bone mineral density (BMD) include or not in Korean FRAX model. OVERVIEW OF LITERATURE Many people with the fracture have osteopenia rather than osteoporosis, and BMD alone could be...

OBJECTIVE The aim of this study is to evaluate fracture risk and post-fracture outcomes in patients with and without liver cirrhosis (LC). DESIGN Retrospective cohort study and nested fracture cohort study. SETTING This study was based on Taiwan's National Health Insurance Research Database that included information on: (1) 3941 patients aged 20 years and older newly diagnosed with LC betwe...
