Traumatic brain injury (TBI) is a major cause of morbidity and mortality among young individuals worldwide. Understanding the pathophysiology of neurotrauma is crucial for the development of more effective therapeutic strategies. After the trauma occurs, immediate neurologic damage is produced by the traumatic forces; this primary injury triggers a secondary wave of biochemical cascades together with metabolic and cellular changes, called secondary neural injury. In the scenario of the acutely injured brain, the ongoing secondary injury results in ischemia and edema culminating in an uncontrollable increase in intracranial pressure...

It was recently described that Galectin-1 (Gal-1) promotes axonal growth after spinal cord injury. This effect depends on protein dimerization, since monomeric Gal-1 fails to stimulate axonal re-growth. Gal-1 is expressed in vivo at concentrations that favor the monomeric species. The aim of the present study is to investigate whether endogenous Gal-1 is required for spinal axon development and normal locomotor behavior in mice. In order to characterize axonal development, we used a novel combination of 3-DISCO technique with 1-photon microscopy and epifluorescence microscopy under high power LED illumination, followed by serial image section deconvolution and 3-D reconstruction...

Diffuse axonal injury is a hallmark pathological consequence of non-penetrative traumatic brain injury (TBI) and yet the axonal responses to stretch injury are not fully understood at the cellular level. Here, we investigated the effects of mild (5%), very mild (0.5%) and repetitive very mild (2×0.5%) axonal stretch injury on primary cortical neurons using a recently developed compartmentalized in vitro model. We found that very mild and mild levels of stretch injury resulted in the formation of smaller growth cones at the tips of axons and a significantly higher number of collapsed structures compared to those present in uninjured cultures, when measured at both 24 h and 72 h post injury...

Recent reports have demonstrated that nearly two-thirds of the world's population do not have access to adequate surgical care, a burden that is borne disproportionately by residents of resource-poor countries. Although the reasons for limited access to surgical care are complex and multi-factorial, among the most substantial barriers is the lack of trained surgical providers. This is particularly true in surgical subspecialties that focus on life-improving, rather than life-saving, treatments, such as pediatric hand and upper extremity surgery, which manages such conditions as congenital malformations, trauma and post-traumatic deformities including burns, and neuromuscular conditions (brachial plexus birth palsy, spinal cord injury, and cerebral palsy)...

BACKGROUND: Stress-induced chronic neuropsychiatric conditions such as anxiety are often co-morbid with gastrointestinal malfunctions. While we find enduring anxiety-like symptoms following minimal traumatic brain injury (MTBI) in rats, gastrointestinal consequences of MTBI remain elusive. METHODS: In this study, we examined the effects of MTBI on a major gut peptide, neuropeptide Y (NPY) and gut motility. DNA methylation was studied as a possible epigenetic mechanism operative in the regulation of NPY expression in the gut...

BACKGROUND: Brain derived neurotrophic factor (BDNF) and Insulin-like growth factor-1 (IGF-1) are essential for neuroplasticity and neuronal survival. Despite the importance of these endogenous factors in mediating post-traumatic recovery, little is known about their response after penetrating type traumatic brain injury (TBI). The objective of this study was to quantify the expression levels BDNF and IGF-1, two well-known neuroplasticity mediators, following penetrating ballistic-like brain injury (PBBI)...

BACKGROUND: The aim of this study was to assess the efficacy of meaning-centered group psychotherapy for cancer survivors (MCGP-CS) to improve personal meaning, compared with supportive group psychotherapy (SGP) and care as usual (CAU). METHOD: A total of 170 cancer survivors were randomly assigned to one of the three study arms: MCGP-CS (n = 57); SGP (n = 56); CAU (n = 57). The primary outcome measure was the Personal Meaning Profile (PMP; total score). Secondary outcome measures were subscales of the PMP, psychological well-being (Scales of Psychological Well-being; SPWB), post-traumatic growth (Posttraumatic Growth Inventory), Mental Adjustment to Cancer (MAC), optimism (Life Orientation Test-Revised), hopelessness (Beck's Hopelessness Scale), psychological distress (anxiety and depression, Hospital Anxiety and Depression Scale; HADS) and quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire; EORTC QLQ-C30)...

Studies have shown that brain-derived neurotrophic factor (BDNF) level increase is associated with post-traumatic stress disorder (PTSD) risk. BDNF may be a "missing-link" that mediates the interaction between genetics, environment, and the sympathetic system. Trauma has been shown to induce DNA methylation that in turn can increase BDNF concentration due to increased gene expression. Therapies that focus on the reduction of beta-NGF (BNGF) levels may impact PTSD symptoms. The focus of this paper is to discuss possible effect of stellate ganglion block (SGB) on epigenetic changes noted with PTSD mediated by BDNF and NGF...

Previous investigations suggest that DL-3-n-butylphthalide (NBP) is a promising multifaceted drug for the treatment of stroke. It is not clear whether NBP can treat traumatic brain injury (TBI) and what could be the mechanisms of therapeutic benefits. To address these issues, TBI was induced by a controlled cortical impact in adult male mice. NBP (100 mg/kg) or saline was intraperitoneally administered within 5 min after TBI. One day after TBI, apoptotic events including caspase-3/9 activation, cytochrome c release from the mitochondria, and apoptosis-inducing factor (AIF) translocation into the nucleus in the pericontusion region were attenuated in NBP-treated mice compared to TBI-saline controls...

OBJECTIVE: Traumatic spinal cord injury (SCI) causes apoptosis of myelin-forming oligodendrocytes (OLs) and demyelination of surviving axons, resulting in conduction failure. Remyelination of surviving denuded axons provides a promising therapeutic target for spinal cord repair. While cell transplantation has demonstrated efficacy in promoting remyelination and functional recovery, the lack of ideal cell sources presents a major obstacle to clinical application. The adult spinal cord contains oligodendrocyte precursor cells and multipotent neural stem/progenitor cells that have the capacity to differentiate into mature, myelinating OLs...

INTRODUCTION: Women in the military are a minority group who, in addition to facing exposure to traumatic events due to the nature of the work, face additional stressors while deployed. It is argued that these exposures and experiences place individuals at a significantly higher risk of finding it difficult adjusting post deployment. This paper focuses on the psychological health and well-being of female veterans post-deployment. METHODS: A systematic review of the literature related to female veterans' experiences upon returning home from deployment was conducted...

Semaphorins comprise a family of proteins involved in axon guidance during development. Semaphorin4D (Sema4D) has both neuroregenerative and neurorepressive functions, being able to stimulate both axonal outgrowth and growth cone collapse during development, and therefore could play an important role in neurological recovery from traumatic injury. Here, we used a zebrafish spinal cord transection model to study the role of Sema4D in a system capable of neuroregeneration. Real-time qPCR and in situ hybridization showed upregulated Sema4D expression in the acute response phase (within 3days post SCI), and downregulated levels in the chronic response phase (11-21days after SCI)...
