Mild traumatic brain injury afflicts over 2 million people annually and little can be done for the underlying injury. The Food Drug Administration-approved drugs Minocycline plus N-acetylcysteine (MINO NAC) synergistically improved cognition memory in a rat mild controlled cortical impact (mCCI) model of injury.3 cellular molecular mechanisms drug combination are unknown. This study addressed effect on white matter damage neuroinflammation after mCCI. Brain tissue from mCCI rats given either...

To compare medical students' and residents' knowledge retention of assessment, diagnosis treatment procedures, as well a learning experience, patients with spinal trauma after training either Virtual Patient case or video-recorded traditional lecture.A total 170 volunteers (85 students 85 residents in orthopedic surgery) were randomly allocated (stratified for student/resident gender) to standard lecture Patient-based session where they interactively assessed clinical portraying motorcycle...

There are no drugs to manage traumatic brain injury (TBI) presently. A major problem in developing therapeutics is that TBI lack sufficient potency when dosed within a clinically relevant time window. Previous studies have shown minocycline (MINO, 45 mg/kg) plus N-acetylcysteine (NAC, 150 synergistically improved cognition and memory, modulated inflammation, prevented loss of oligodendrocytes remyelinated damaged white matter first 1 h after controlled cortical impact (CCI) rats. We show...

Blunt impact produces a heterogeneous brain injury in people and animal models of traumatic injury. We report that single closed head to adult C57/BL6 mice produced two syndromes (CHI-1 CHI-2). CHI-1 spontaneously reinitiated breathing after while CHI-2 had prolonged apnea regained only cardiopulmonary resuscitation supplementation 100% O2. The group significantly righting reflex more rapidly than the group. At 7 days post-injury, CHI-1, but not mice, acquired no long-term retention an...

A method to automatically generate finite element (FE) head models is presented in this paper. Individual variation geometry of the should be taken into consideration future injury-prediction research. To avoid inter- and intra-operator due manual segmentation, a robust accurate algorithm suggested. The current approach utilises expectation maximisation classification skull stripping. whole process from extraction model generation converted an automatic scheme. that are generated proposed...

This study examined whether peripheral vision reaction time (PVRT) in patients with mild traumatic brain injury (mTBI) correlated white matter abnormalities centroaxial structures and impairments neuropsychological testing. Within 24 h after mTBI, crossed times (CRT), uncrossed (URT), crossed-uncrossed difference (CUD) were measured 23 using a laptop computer that displayed visual stimuli predominantly to either the left or right field of retina. The CUD is surrogate marker interhemispheric...

Transcranial Direct Current Stimulation (tDCS) is a non-invasive procedure where weak electrical current (260 μA to 2 mA) applied across the scalp modulate brain function. tDCS has been for therapeutic purposes (e.g., addiction, depression, mood and sleep disorders) as well cognitive performance enhancement memory consolidation, motor learning language recall). Despite safety cost advantages, developments of therapies have restricted by spatial targeting concerns using existing two-channel...

This RCT study aimed to investigate if VIS-Ed (Visualization through Imaging and Simulation - Education) had the potential improve medical student education specialist training in clinical diagnosis treatment of trauma patients. The participants' general opinion was reported as high both groups (lecture vs. virtual patient (VP)). Face validity for cervical spine demonstrated VP group higher stimulation engagement compared lecture group. No significant difference knowledge test between could...
