Dietary Zinc Modulates Matrix Metalloproteinases in Traumatic Brain Injury.

Animal models of mild traumatic brain injury (mTBI) provide opportunity to examine the extent to which dietary interventions can be used to improve recovery after injury. Animal studies also suggest that matrix metalloproteinases (MMPs) play a role in tissue remodeling post-TBI. Because dietary zinc (Zn) improved recovery in nonblast mTBI models, and the MMPs are Zn-requiring enzymes, we evaluated the effects of low- (LoZn) and adequate-Zn (AdZn) diets on MMP expression and behavioral responses, subsequent to exposure to a single blast.

Worries and needs of adults and parents of adults with neurofibromatosis type 1.

Neurofibromatosis type 1 (NF1) is a neurocutaneous disorder associated with lifelong tumor growth propensity and neurocognitive impairments. Although follow-up of adults with NF1 often focuses on tumor growth, follow-up of cognitive or social problems and other NF1-related comorbidity is often not a part of standardized care. In order to provide optimal care services for these patients, we explored the care needs of adults with NF1.

Timing of decontamination and treatment in case of percutaneous VX poisoning: a mini review.

Low volatile organophosphorous nerve agents such as VX, will most likely enter the body via the skin. The pharmacokinetics of drugs such as oximes, atropine and diazepam, are not aligned with the variable and persistent toxicokinetics of the agent. Repeated administration of these drugs showed to improve treatment efficacy compared to a single injection treatment.

Toxic effects following phosgene exposure of human epithelial lung cells in vitro using a CULTEX® system.

The aim of the present study was to investigate toxic effects following phosgene exposure of human epithelial lung cells (A549) in vitro using a CULTEX® system. In particular, toxic effects regarding early biomarkers emerging during the latency period following exposure might be of great value for medical treatment. Cells cultured on semi-permeable membranes were directly exposed at the liquid-air interface to different concentrations of phosgene, or dry medical air.
