Traumatic brain injury is a leading cause of mortality and morbidity among young people. For the last couple of decades, it was believed that excess stimulation of brain receptors for the excitatory neurotransmitter glutamate was a major cause of delayed neuronal death after head injury, and several major clinical trials in severely head injured patients(More)
Memory and neurobehavioral dysfunctions are among the sequelae of traumatic brain injury (TBI). The Neurological Severity Score (NSS) includes 10 tasks and was previously designed to assess the functional status of mice after TBI. The object recognition task (ORT) measures specific episodic memory and is expressed by the percent time spent by an animal at a(More)
Traumatic brain injury triggers a massive glutamate efflux, activation of NMDA receptor channels, and cell death. Recently, we reported that NMDA receptors in mice are down-regulated from hours to days following closed head injury (CHI), and treatment with NMDA improved recovery of motor and cognitive functions up to 14 d post-injury. Here we show that a(More)
Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in young people in industrialized countries. Although various anti-inflammatory and antiapoptotic modalities have shown neuroprotective effects in experimental models of TBI, to date, no specific pharmacological agent aimed at blocking the progression of secondary brain damage has(More)
1 The psychological profile of 17 Complex Regional Pain Syndrome type I (CRPS) and 20 Conversion Disorder (CD) patients were compared, using the Minnesota Multiphasic Personality Inventory (MMPI) and standardized, semistructured psychological interviews. Both groups presented abnormally high somatization scores. Low anxiety scores in both groups indicate(More)
Traumatic brain injury (TBI) is a major cause of death and disability worldwide. It causes progressive tissue atrophy and consequent neurological dysfunctions. TBI is accompanied by neuroinflammation, a process mediated largely by microglia. CD38 is an ectoenzyme that promotes transmembrane signaling via the synthesis of potent calcium mobilizing agents or(More)
Long-term heat exposure, known as heat acclimation (HA; 30 days at 34 +/- 1 degrees C) is neuroprotective against traumatic brain injury. Acclimated mice were previously found to display improved functional recovery as well as an increase in the levels of the specific erythropoietin receptor. As the activation of this receptor is known to facilitate(More)
PRIMARY OBJECTIVE To describe the outcomes of terror victims suffered from traumatic brain injury (TBI). RESEARCH DESIGN Retrospective chart review of 17 terror and 39 non-terror TBI patients treated in a rehabilitation department during the same period. METHODS AND PROCEDURE Variables include demographic data, Injury Severity Scale (ISS), length of(More)
Both heat acclimation (HA) and post-injury treatment with recombinant human erythropoietin (Epo, rhEpo, exogenous Epo) are neuroprotective against traumatic brain injury (TBI). Our previous data demonstrated that HA-induced neuroprotection includes improved functional recovery and reduced cerebral edema formation. Additionally, in earlier Western-blot(More)
Familial dysautonomia (FD) is an autosomal recessive congenital neuropathy, primarily presented in Ashkenazi Jews. The most common mutation in FD patients results from a single base pair substitution of an intronic splice site in the IKBKAP gene which disrupts normal mRNA splicing and leads to tissue-specific reduction of IKBKAP protein (IKAP). To date,(More)
