2. 1. Modelling of Diffuse Brain Injury: Combining Methods to Study Possible Links between Transient Intracranial Pressure and Injury

   Author : Ulrika Krave; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; animal model; astrocytosis; diffuse axonal injury; neurofilaments; diffuse brain injury; rotational acceleration; closed head trauma; rabbit; finite element analysis; intracranial pressure; injury mechanisms;

   Abstract : The objectives of this research are the study of sagittal rotational acceleration induced diffuse brain injury mechanisms. Such injuries are common in vehicle accidents in particular; the consequences range from mild to severe symptoms and may lead to persistent neurological dysfunction. READ MORE

4. 2. Clinical Consequences of Axonal Injury in Traumatic Brain Injury

   Author : Sami Abu Hamdeh; Niklas Marklund; Per Enblad; Lars Hillered; Andreas PhD Unterberg MD; Uppsala universitet; []
   Keywords : Traumatic brain injury; diffuse axonal injury; intracranial pressure; magnetic resonance imaging; amyloid-beta; tau; Neurokirurgi; Neurosurgery;

   Abstract : Traumatic brain injury (TBI), mainly caused by road-traffic accidents and falls, is a leading cause of mortality. Survivors often display debilitating motor, sensory and cognitive symptoms, leading to reduced quality of life and a profound economic burden to society. READ MORE

5. 3. Oligodendrocyte pathology following Traumatic Brain Injury : Experimental and clinical studies

   Author : Johanna Flygt; Niklas Marklund; Fredrik Piehl; Uppsala universitet; []
   Keywords : Traumatic brain injury; oligodendrocytes; oligodendrocyte progenitor cells; interleukin 1-β; central fluid percussion injury; Neurokirurgi; Neurosurgery; Neurokirurgi; Neurosurgery;

   Abstract : Traumatic brain injury (TBI) caused by traffic and fall accidents, sports-related injuries and violence commonly results in life-changing disabilities. Cognitive impairments following TBI may be due to disruption of axons, stretched by the acceleration/deceleration forces of the initial impact, and their surrounding myelin in neuronal networks.

6. 4. Assessment of experimental neurotrauma

   Author : Ying-Lai Huang; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Impulse noise; diffuse brain injury; focal brain injury; closed head injury; NSE; S-100; GFAP; apoptosis; astrocytosis; glutamate; c-JUN; rotational acceleration; CSF;

   Abstract : Model systems of closed head injury are designed to replicate aspects of traumatic brain injury, ischemia and epilepsy in man. The aim of this thesis was to (1) develop sensitive systems enabling analyses of the biochemical reactions, as reflected by leakage of marker compounds to the cerebrospinal fluid (CSF); and (2) develop and assess a new model for closed head injury and associated dynamic changes in the brain cell.

7. 5. Cellular Reactions and Behavioral Changes in Focal and Diffuse Traumatic Brain Injury : A Study in the Rat and Mouse

   Author : Sara Ekmark Lewén; Lars Hillered; Niklas Marklund; Anders Lewén; Mårten Risling; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Astrocytes; Inflammatory response; Multivariate concentric square field test; Morris water maze; Exploratory behavior; Risk taking; Functional outcome.; Neurosurgery; Neurokirurgi;

   Abstract : Traumatic brain injury (TBI) is a severe condition and a major cause of death and disability. There is no pharmacological treatment available in clinical practice today and knowledge of brain injury mechanisms is of importance for development of neuroprotective drugs. READ MORE
