ABSTRACT Trauma is the most common reason of death in 1-44 years olds. In patients with multiple rtrauma, the head is the most common involved part . Car accident is the most common cause of head injury in adults. The importance of computed tomography (CT) in diagnosis of brain trauma is well estabilished and CT of the brain is a choice method. A descriptive study was carried out in 880 patie...
Background and Objectives: Iran is a large country that is often an importer of major medical equipment. There is no comprehensive databank of the status of the equipment in the country. The present study provides a clear description of the dispersal status of major medical equipment in the country in 2016 and the estimated number of required devices in 2026. Methods: This study was conduct...
A total of 31 adult patients with moderate and severe head injury were assessed clinically on admission for Glasgow Coma Scale (GCS) and short test of mental status (STMS) on follow-up and compared to their initial and follow up CT scan. Good predictors were admission GCS, midline shift, volume of subdural haemorrhage in the initial CT scan of the brain as well as the presence of post-traumatic...
Motivation: Although 2D images lack significant information that is present in 3D modalities, they might be conveniently and efficiently used to record details about the most current state of the imaged object. The most amount of information can be gained about the changes recorded by the 2D modalities and the detailed 3D model if we fuse the information provided by both of them. In order to ac...
background: bisphosphonates (bps) are used extensively for managing the osteoporosis. there are some controversies on atypical fractures of femur that associated with increase in cortical thickness (ct) and bps' use. in this study, the effects of alendronate consumption were studied on femoral ct as a predictor for atypical fracture. methods: forty nine post-menopausal women aged 50-70 years ...
We study two models for the formation and packing of helices and sheets in globular (compact) proteins. These models, based on weighted Hamiltonian paths on a regular lattice both exhibit a first order transition between a compact high temperature phase, with no extended secondary structures, and a quasi-frozen compact phase, with secondary structures invading the whole lattice. The quasi-froze...
