Free radical scavenger posttreatment improves functional and morphological outcome after fluid percussion injury in the rat

Reactive oxygen species (ROS) are thought to contribute to the secondary injury process after traumatic brain injury (TBI). ROS scavenging compounds have shown neuroprotective properties in various models of experimental brain injury, including TBI. Administration of nitrone radical scavengers has emerged as a promising pharmacological concept in focal experimental ischemia due to their low toxici

Effect of traumatic brain injury and nitrone radical scavengers on relative changes in regional cerebral blood flow and glucose uptake in rats

Changes in regional cerebral blood flow (rCBF) and glucose metabolism are commonly associated with traumatic brain injury (TBI). Reactive oxygen species (ROS) have been implicated as key contributors to the secondary injury process after TBI. Here, pretreatment with the nitrone radical scavengers (alpha-phenyl-N-tert-butyl nitrone (PBN) or its sulfonated analogue sodium 2-sulfophenyl-N-tert-butyl

Impact of amoxicillin therapy on resistance selection in patients with community-acquired lower respiratory tract infections : A randomized, placebo-controlled study

Objectives: To determine the effect of amoxicillin treatment on resistance selection in patients with community-acquired lower respiratory tract infections in a randomized, placebo-controlled trial. Methods: Patients were prescribed amoxicillin 1 g, three times daily (n = 52) or placebo (n = 50) for 7 days. Oropharyngeal swabs obtained before, within 48 h post-treatment and at 28-35 days were asse

Administration of monoclonal antibodies neutralizing the inflammatory mediators tumor necrosis factor alpha and interleukin -6 does not attenuate acute behavioral deficits following experimental traumatic brain injury in the rat

PURPOSE: Although many previous studies have indicated that the acute inflammatory response following traumatic brain injury (TBI) is detrimental, inflammation may also positively influence outcome in the more chronic post-injury recovery period. We evaluated the effects of monoclonal antibodies (mAB), neutralizing either IL-6 (IL-6 mAB) or TNF-alpha (TNF mAB), administered intracerebroventricular

Selective temporal and regional alterations of Nogo-A and small proline-rich repeat protein 1A (SPRR1A) but not Nogo-66 receptor (NgR) occur following traumatic brain injury in the rat

Axons show a poor regenerative capacity following traumatic central nervous system (CNS) injury, partly due to the expression of inhibitors of axonal outgrowth, of which Nogo-A is considered the most important. We evaluated the acute expression of Nogo-A, the Nogo-66 receptor (NgR) and the novel small proline-rich repeat protein 1A (SPRR1A, previously undetected in brain), following experimental l

Cognitive outcome following brain injury and treatment with an inhibitor of Nogo-A in association with an attenuated downregulation of hippocampal growth-associated protein-43 expression

OBJECT: Central nervous system axons regenerate poorly after traumatic brain injury (TBI), partly due to inhibitors such as the protein Nogo-A present in myelin. The authors evaluated the efficacy of anti-Nogo-A monoclonal antibody (mAb) 7B12 administration on the neurobehavioral and cognitive outcome of rats following lateral fluid-percussion brain injury, characterized the penetration of the 7B1
