BACKGROUND Although conservative treatment is a well-established method for treating nondisplaced and minimally displaced (< or =2 mm) fractures of the lateral humeral condyle in children, there is still great uncertainty concerning the rate and time course of subsequent displacement. Therefore, the appropriate frequency of radiographic follow-up remains unclear. The aim of the study was to det...

This study compares postural and trunk responses to translating platform perturbations of varied velocities and directions. A group of 18 young and physically active subjects were exposed to a set of postural perturbations at varied velocities (5, 10, 15, and 20 cm/s) and directions of platform movement (forward, backward, left-lateral, and right-lateral). The center of pressure (CoP) displacem...

Abstract Background Ulnar head fractures are increasingly higher with the growing proportion of elderly people. Failure to achieve a stable anatomic reduction ulna fracture may lead distal radioulnar joint (DRUJ) dysfunction and nonunion radius. Due lack postoperative reporting outcomes biomechanical studies, it has not been well established about optimal management comminuted fracture. Hence, ...

The objective of this research is to develop neck injury criteria and injury tolerance levels to be used as a basis for a performance standard for the certification of side facing aircraft seats. This paper presents the results of the first part of this study. A literature review was performed on the neck injuries, kinematics and injury mechanisms in lateral loading and existing injury criteria...

Deterministic lateral displacement arrays have shown great promise for size-based particle analysis and purification in medicine and biology. Here, we demonstrate that the use of an array of triangular rather than circular posts significantly enhances the performance of these devices by reducing clogging, lowering hydrostatic pressure requirements, and increasing the range of displacement chara...

BACKGROUND Submandibular gland transfer has been widely used to prevent postradiation xerostomia in head-and-neck cancers. However, there are still some controversies. METHODS Six databases were searched, data extraction was performed and the risk of bias was assessed by 2 reviewers independently. The meta-analysis was performed using Review Manager, version 5.2. RESULTS A total of 7 trials...

concrete filled steel tube columns (cfst) are a kind of composite columns according to advantages of cfst relative to reinforced concrete and steel columns. use of these materials is common in recent years especially in high building, unnecessary of molding, high ductility, proportionate resistance with low volume, economical, low deformation relative to steel columns are among advantages. in t...
