A number of preclinical rodent models have been developed in an effort to recapitulate injury mechanisms and identify potential therapeutics for traumatic brain injury (TBI), which is a major cause of death and long-term disability in the United States. However, the lack of restorative treatments for TBI has led to considerable criticism of current preclinical therapeutic development strategies, namely the translatability of widely-used rodent models to human patients. The use of large animal models, such as the pig, with more comparable brain anatomy and physiology to humans may enhance the translational capacity of current preclinical animal models...

Traumatic brain injury (TBI) is an intracranial injury which can induce immediate neuroinflammation and long-term neurological deficits. Methylene blue (MB) as a nootropic has a great potential to treat neurodegeneration after TBI because of its anti-inflmmatory and neuroprotective functions. However, its limited accumulation to the brain across the blood-brain barrier (BBB) remains a major hurdle to be overcome. In this paper, we present a polymer surfactant-encapsulated nanocomplex of MB as a delivery system with high BBB permeability for efficacious treatment of TBI-induced neurodegeneration...

INTRODUCTION: Studies have shown an increased risk of traumatic brain injury (TBI) for individuals who suffer an initial TBI. The current study hypothesized that individuals with recurrent neurotrauma would originate from populations considered 'vulnerable', i.e. low income and/or with psychiatric comorbidities. METHODS: Data from the Michigan State Inpatient Database from 2006 to 2014 for the Detroit metropolitan area enlisted a study population of 50 744 patients with neurotrauma...

Traumatic brain injury (TBI) affects 1.9 million Americans, including blast TBI that is the signature injury of the Iraq and Afghanistan wars. Our project investigated whether stromal vascular fraction (SVF) can assist in post-TBI recovery. We utilized strong acoustic waves (5.0 bar) to induce TBI in the cortex of adult Rowett Nude (RNU) rats. One hour post-TBI, harvested human SVF (500,000 cells suspended in 0.5 mL lactated Ringers) was incubated with Q-Tracker cell label and administered into tail veins of RNU rats...

Stem cells transplantation has emerged as a promising alternative therapeutic due to its potency at injury site. The need to monitor and non-invasively track the infused stem cells is a significant challenge in the development of regenerative medicine. Thus, in vivo tracking to monitor infused stem cells is especially vital. In this manuscript, we have described an effective in vitro labelling method of MSCs, a serial in vivo tracking of implanted stem cells at traumatic brain injury (TBI) site through 7 T magnetic resonance imaging (MRI)...

More than 10 million people worldwide incur a traumatic brain injury (TBI) each year, with two million cases occurring in the United States. TBI survivors exhibit long-lasting cognitive and affective sequelae that are associated with reduced quality of life and work productivity, as well as mental and emotional disturbances. While TBI-related disabilities often manifest physically and conspicuously, TBI has been linked with a "silent epidemic" of psychological disorders, including major depressive disorder (MDD)...

Traumatic brain injury (TBI) is the main cause of disability in people younger than 35 in the United States. The mechanisms of TBI are complex resulting in both focal and diffuse brain damage. Fractal dimension (FD) is a measure that can characterize morphometric complexity and variability of brain structure especially white matter (WM) structure and may provide novel insights into the injuries evident following TBI. FD-based brain morphometry may provide information on WM structural changes after TBI that is more sensitive to subtle structural changes post injury compared to conventional MRI measurements...

BACKGROUND: This study demonstrated the effects of traumatic brain injury (TBI) and each step of the surgical procedure for a fluid percussion injury (FPI) model on periorbital allodynia. NEW METHOD: Adult male Wistar rats were divided in naive, incision, scraping, sham-TBI and TBI groups. Periorbital allodynia was evaluated using von Frey filaments, and heat hyperalgesia of the hindpaws was evaluated by a Plantar Test Apparatus. RESULTS: The statistical analyses revealed that the surgical procedure decreased von Frey filaments thresholds twenty-four hours after the surgery in all groups when compared to the naive group (p < 0...

BACKGROUND: Several studies have recently found that oxidative stress plays a pivotal role in the pathogenesis of traumatic brain injury (TBI) and may represent a target in TBI treatment. Hydrogen-rich water was recently shown to exert neuroprotective effects in various neurological diseases through its antioxidant properties. However, the mechanisms underlying its effects in TBI are not clearly understood. The purpose of our study was to evaluate the neuroprotective role of hydrogen-rich water in rats with TBI and to elucidate the possible mechanisms underlying its effects...

Evidence supports olanzapine for prophylaxis of chemotherapy-induced nausea/vomiting (CINV) for highly emetogenic chemotherapy (HEC); however, most studies focus on solid malignancies and single day regimens. A randomized, double-blinded, placebo-controlled trial was conducted to compare addition of olanzapine to triplet therapy (fosaprepitant, ondansetron, dexamethasone; FOND-O) versus triplet therapy alone (FOND) in preventing CINV in hematology patients receiving single and multi-day HEC and hematopoietic cell transplant (HCT) regimens (NCT02635984)...

Hyperosmolar therapy is regarded as the mainstay for treatment of elevated intracranial pressure (ICP) in traumatic brain injury (TBI). This still has been disputed as application of hypertonic saline (HS) or mannitol for treating patients with severe TBI. Thus, this meta-analysis was performed to further compare the advantages and disadvantages of mannitol with HS for treating elevated ICP after TBI. We conducted a systematic search on PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Wan Fang Data, VIP Data, SinoMed, and China National Knowledge Infrastructure (CNKI) databases...

Background: Traumatic brain injury (TBI) is known to impact dopamine-mediated reward pathways, but the underlying mechanisms have not been fully established. Methods: Nicotine-induced conditional place preference (CPP) was used to study rats exposed to a 6-psi fluid percussion injury (FPI) with and without prior exposure to nicotine. Preference was quantified as a score defined as (C1-C2) / (C1+C2), where C1 is time in the nicotine-paired compartment and C2 is time in the saline-paired compartment...

Although facial affect recognition deficits are well documented in individuals with moderate-to-severe traumatic brain injury (TBI), little research has examined the neural mechanisms underlying these impairments. Here, we use diffusion tensor imaging (DTI), specifically the scalars fractional anisotropy (FA), mean diffusivity (MD), and radial diffusivity (RD), to examine relationships between regional white-matter integrity and two facial affect sub-skills: perceptual affect recognition abilities (measured by an affect matching task) and verbal categorization of facial affect (measured by an affect labeling task)...
