James Brady, the White House press secretary during President Ronald Reagan's first term in office, was 1 of 4 people (including the President) wounded during an attempted assassination attempt on President Reagan's life on March 30, 1981. John Hinckley, Jr. was found not guilty of this attempt by reason of insanity. The assassination attempt was a ploy by Hinckley, Jr. to impress the actress Jodie Foster. Brady was the most seriously injured of the 4 who were wounded. He suffered a gunshot wound to the left forehead that traveled through the left frontal lobe, corpus callosum, and then into the right frontal and temporal lobes...

AIM: To address the hypothesis that young, gonad-intact female mice have improved long-term recovery associated with decreased neuroinflammation compared to male mice. METHODS: Eight to ten week-old male, female, and ovariectomized (OVX) mice underwent closed cranial impact. Gonad-intact female mice were injured only in estrus state. After injury, between group differences were assessed using complementary immunohistochemical staining for microglial cells at 1 h, mRNA polymerase chain reaction for inflammatory markers at 1 h after injury, Rotarod over days 1-7, and water maze on days 28-31 after injury...

In the general population, females experience depression at significantly higher rates than males. Individuals with traumatic brain injury (TBI) are at substantially greater risk for depression compared to the overall population. Treatment of, and recovery from, TBI can be hindered by depression; comorbid TBI and depression can lead to adverse outcomes and negatively affect multiple aspects of individuals' lives. Gender differences in depression following TBI are not well understood, and relevant empirical findings have been mixed...

Alkali burn injury is a true ocular emergency of the conjunctiva and cornea that requires immediate precision. Lack of an immediate therapy can lead to a substantial damage in the ocular surface and anterior segment further causing visual impairment and disfigurement. We explored the regenerative capability of dominant negative survivin protein (SurR9-C84A) and histone deacetylase inhibitor trichostatin-A (TSA) in vivo, in a rat alkali burn model. A topical insult in rat eyes with NaOH led to degradation of the conjunctival and corneal epithelium...

Current treatment options for spinal cord injury (SCI) are scarce. One of the most promising innovative approaches include gene-therapy, however no single gene has so far been shown to be of clinical relevance. This study investigates the efficacy of various combinations of vascular endothelial growth factor (VEGF), glial cell-derived neurotrophic factor (GDNF), angiogenin (ANG) and neuronal cell adhesion molecule (NCAM) in rats. Multiple therapeutic genes were administered intrathecally either via adenoviral vectors or by using genetically modified human umbilical cord blood mononuclear cells (hUCBMCs)...

Recently, bile acids (BAs) were reported as promising markers for drug-induced liver injury (DILI). BAs have been suggested to correlate with hepatocellular and hepatobiliary damage; however a clear connection of BA patterns with different types of DILI remains to be established. To investigate if BAs can improve the assessment of liver injury, 20 specific BAs were quantitatively profiled via LC-MS/MS in plasma and liver tissue in a model of methapyrilene-induced liver injury in rats. Methapyrilene, a known hepatotoxin was dosed daily over 14-days at doses of 30 and 80mg/kg, followed by a recovery phase of 10 days...

Nicotinamide phosphoribosyltransferase (NAMPT) is an important neuroprotective factor in cerebral ischemia, and it has been reported that NAMPT inhibitors can aggravate neuronal injury in the acute phase. However, because it is a cytokine, NAMPT participates in many inflammatory diseases in the peripheral system, and its inhibitors have therapeutic effects. Following cerebral ischemia, the peripheral and resident inflammatory and immune cells produce many pro-inflammatory mediators in the ischemic area, which induce neuroinflammation and impair the brain...

Lead is considered a highly toxic contaminant with important impacts to bird wildlife. Griffon vultures (Gyps fulvus) are a sensitive indicator of the level of environmental contamination due to their position at the top of the food chain and their dependence on human activities. The aim of this study was to assess susceptibility to lead intoxication in Griffon vultures admitted to Wildlife Rehabilitation Centers (WRC), measuring blood lead levels and determining if blood lead concentrations are related to clinical signs, hematological, biochemical or radiographic findings...

Following recurrent laryngeal nerve (RLN) injury, recovery results in poor functional restitution of the paralyzed vocal fold. Netrin-1 has been found to be upregulated in the rat posterior cricoarytenoid muscle (PCA) during nerve regeneration, We evaluated the effect of ectopic Netrin-1 in the PCA during RLN reinnervation. The right RLN was transected and Netrin-1 was injected into the PCA (2.5, 5, 10, 15, 20μg/ml). At 7 days post injury fluorescent retrograde tracer was injected into PCA and Thyroarytenoid (TA) muscles...

INTRODUCTION: Children increasingly are being seen in the emergency department for a concussion, or mild traumatic brain injury (mTBI). A key aim of the ED visit is to provide discharge advice that can help parents to identify an evolving neurosurgical crisis, facilitate recovery, and prevent reinjury. The present study examined parents' knowledge of symptoms and recall of discharge instructions after their adolescent's mTBI and the effect of supplementing written discharge instructions with verbal instruction and reinforcement...

Traumatic spinal cord injury (SCI) is a major challenge in the clinic. In this study, we sought to examine the synergistic effects of linear ordered collagen scaffold (LOCS) and human placenta-derived mesenchymal stem cells (hPMSCs) when transplanted into completely transected beagle dogs. After 36 weeks observation, we found that LOCS+hPMSCs implants promoted better hindlimb locomotor recovery than was observed in the non-treatment (control) group and LOCS group. Histological analysis showed that the regenerated tissue after treatment was well integrated with the host tissue, and dramatically reduced the volume of cystic and chondroitin sulfate proteoglycans (CSPGs) expression...

As head injuries and their sequelae have become an increasingly salient matter of public health, experts in the field have made great progress elucidating the biological processes occurring within the brain at the moment of injury and throughout the recovery thereafter. Given the extraordinary rate at which our collective knowledge of neurotrauma has grown, new insights may be revealed by examining the existing literature across disciplines with a new perspective. This article will aim to expand the scope of this rapidly evolving field of research beyond the confines of the central nervous system (CNS)...

Intracerebral haemorrhage (ICH) is the most lethal subtype of stroke but currently lacks effective treatment. Microglia are among the first non-neuronal cells on the scene during the innate immune response to ICH. Microglia respond to acute brain injury by becoming activated and developing classic M1-like (proinflammatory) or alternative M2-like (anti-inflammatory) phenotypes. This polarization implies as yet unrecognized actions of microglia in ICH pathology and recovery, perhaps involving microglial production of proinflammatory or anti-inflammatory cytokines and chemokines...

Asparaginase is a chemotherapeutic agent that is commonly used in combination with other medications for the treatment of acute lymphoblastic leukemia. An adverse effect of asparaginase includes hepatotoxicity, which can lead to severe liver failure and death. Several reports have documented successful treatment of asparaginase-induced hepatotoxicity using levocarnitine (l-carnitine) and vitamin B complex. Herein, we report a patient with acute lymphoblastic leukemia that experienced acute liver injury following pegaspargase administration...

PURPOSE: Ischemia-associated retinal degeneration is one of the leading causes of vision loss, and to date, there are no effective treatment options. We hypothesized that delayed injection of bone-marrow stem cells (BMSCs) 24 h after the onset of ischemia could effectively rescue ischemic retina from its consequences, including apoptosis, inflammation, and increased vascular permeability, thereby preventing retinal cell loss. METHODS: Retinal ischemia was induced in adult Wistar rats by increasing intraocular pressure (IOP) to 130-135 mmHg for 55 min...

Patients in the process of recovering from severe bodily injury will encounter several barriers to effective treatment. When present, untreated hearing loss can create additional obstacles in a process that is already difficult. This article describes an outpatient post-trauma clinic associated with a tertiary care hospital trauma unit that consolidates rehabilitation resources 2 weeks after inpatient discharge to help these patients on their path to recovery. The role of audiology in the interdisciplinary clinic is described and data related to services are presented...
