AIMS Traumatic brain injury (TBI) occurs when the head is impacted by an external force causing either a closed or penetrating head injury through a direct or accelerating impact. In laboratory research, most of the TBI animal models focus on a specific region to cause brain injury, but traumatic injuries in patients do not always impact the same brain regions. The aim of this study was to exam...

Mitochondria play central roles in acute brain injury; however, little is known about mitochondrial function following traumatic brain injury (TBI) to the immature brain. We hypothesized that TBI would cause mitochondrial dysfunction early (<4 h) after injury. Immature rats underwent controlled cortical impact (CCI) or sham injury to the left cortex, and mitochondria were isolated from both hem...

Traumatic brain injury (TBI) is a significant source of morbidity and mortality in the adult population. The management of traumatic brain injury depends on its severity. It must be recognized that almost all forms of treatment for TBI are geared towards the minimization of secondary injury, as it is assumed that primary injury is irreversible. The discussion here represents much of what is kno...

Abstract Introduction Traumatic brain injury (TBI) is a global public health burden. Although neurogenesis occurs post-injury, achieving long term survival of newly generated neurons remains elusive. High Mobility Group Box protein 1 (HMGB1) pivotal cytokine in hosting the neuro-inflammatory response to injury, but also mediates during physiological development. In this review, we examine curre...

Traumatic brain injury (TBI) is a leading cause of death and disability among children and young adults in the United States. In this study, we explored whether changes in the gene expression profile of peripheral blood mononuclear cells (PBMC) may provide a clinically assessable "window" into the brain, reflecting molecular alterations following TBI that might contribute to the onset and progr...

Traumatic brain injury (TBI) has proven to be a major public health problem with an annual incidence of over 1.5 million people (Langlois, Rutland-Brown, & Thomas, 2006). Medical advances have contributed to increasing the survival rate of TBI allowing many individuals with varying severities of TBI to receive treatment from the ER and be discharged immediately to their home or receive addition...

Severe traumatic brain injury (TBI) often leads to deficits in physiological arousal and empathy, which are thought to be linked. This study examined whether injury-related brain volume loss in key limbic system structures is associated with these deficits. Twenty-four adults with TBI and 24 matched Controls underwent MRI scans to establish grey matter volumes in the amygdala, thalamus, and hip...

The multifactorial nature of traumatic brain injury (TBI), especially the complex secondary tissue injury involving intertwined networks of molecular pathways that mediate cellular behavior, has confounded attempts to elucidate the pathology underlying the progression of TBI. Here, systems biology strategies are exploited to identify novel molecular mechanisms and protein indicators of brain in...

Traumatic brain injury (TBI), which results from an outside force causing mechanical disruption of brain tissue, is potentially life-threatening and therefore a critical public health problem throughout the world. In the USA, approximately 1.7 million individuals per year sustain a TBI, and about 43% of patients hospitalized because of TBI develop long-term physical disability as well as psycho...

Traumatic cerebral vascular injury (TCVI) is a frequent, perhaps universal, feature after traumatic brain injury (TBI) and may be responsible for for some TBI-related chronic disabilities. Because there are multiple pharmacologic and non-pharmacologic therapies that promote vascular health, TCVI is an attractive target for therapeutic intervention after TBI. The cerebral microvasculature (CMV) ...
