The nonlinear viscoelastic behavior of brain tissue that was observed in oscillatory shear tests was modeled with a quasilinear viscoelastic constitutive relation. The dynamic viscoelastic behavior of brain tissue has been previously modeled with only linear models. The reader is referred to Darvish (2000) for a review of the previous models. Studies on live neural tissue (Thibault et al., 1990...

The prediction and prevention of traumatic brain injury, spinal injury and musculo-skeletal injury is a very important aspect of preventive medical science. Recently, in a series of papers [1, 2, 3], I have proposed a new coupled loading-rate hypothesis as a unique cause of all above injuries. This new hypothesis states that the main cause of all mechanical injuries is a Euclidean Jolt, which i...

traumatic brain injury resulting road accidents create damage to the brain. the severe brain injury may cause extensive tissue loss of several parenchyma which results in cavities due to primary destruction and secondary injuries such as ischemia and inflammation. recent findings suggest that neuronal precursors in the adult mammalian brain can be a therapeutic target in ischemic brain injuries...

Penetrating orbital trauma necessitates a multidisciplinary approach because complex injuries often encompass damage to the brain, eyes, and disfigurement of face.

computed tomography (ct) is now the primary diagnostic method for head trauma because of its ability to demonstrate the nature, extent, sites, and multiplicity of brain injuries. although there have been numerous reports on the ct findings of most types of intracranial injury, the findings in brainstem injury have not been well described. this study aimed at comparing the autopsy findings of br...

BACKGROUND AND PURPOSE Comparisons of spontaneous movements of premature infants with brain injuries and those without brain injuries can provide insights into normal and abnormal processes in the ontogeny of motor development. In this study, the characteristics of spontaneous upper-extremity movements of premature infants with brain injuries and those without brain injuries were examined with ...

Introduction: Arterial hypertension is one of the causes of stroke, and as one of the vasculotoxic conditions intensifies ischemic stroke complications. The aim of the present study was to analyze the effects of short-term cerebral hypertension on ischemia/reperfusion injury and pathogenesis of ischemic stroke. Methods: The experiments were performed on three groups of rats (N=36) Sham, cont...

today, stem cell transplantation is a hot topic in scientific circles as a novel therapeutic approach to repair the structure and function of central nervous system. the safe and neuroprotective effects of cell therapy in models and traumatic brain injury patients were evaluated in many experimental and clinical studies in recent decade and somewhat promising results were provided to the scient...

Objective: One of the most frequent causes of death and acquired disability in the pediatric population is the Traumatic Brain Injury (TBI). TBI is secondary to falls, road traffic and vehicle collisions, child abuse and assaults. Penetrating brain injury is a severe form of traumatic brain injury. Blunt head injury is more frequent than TBI in children, but the second one carries a poor progno...

BACKGROUND With the onset of improved protective equipment against fragmentation, blast-induced neurotrauma has emerged as the "signature wound" of the current conflicts in the Middle East. Current research has focused on this phenomenon; however, the exact mechanism of injury and ways to mitigate the ensuing pathophysiology remain largely unknown. The data presented and literature reviewed for...
