W hile musing upon the request to write an indigenous pediatrician’s perspective of the state of play of injury control in South America, particularly as to why matters remain at a rather primitive level and what could be done to move things along, I was struck by this news item: a newspaper in my hometown in southern Brazil reported that a unidentified motorcyclist had fired two gunshots at a ...
Paranodal junctions that flank nodes of Ranvier contain a cytoskeleton specialized to prevent membrane protein diffusion in and out of the nodes. This week Ogawa et al. used three known paranodal cell adhesion molecules to fish out additional paranodal molecules. As starting material, the authors isolated optic nerve membranes enriched in glial protein NF155 and the axonal proteins Caspr and co...
Do people derive more enjoyment from activities that match how they ideally want to feel (their "ideal affect")? Affect valuation theory (AVT) predicts that they do; however, no study has directly examined whether this is the case. Therefore, the authors conducted 4 studies that examined whether valuing calm and other low arousal positive states (LAP) increased enjoyment of calming (vs. excitin...
Traffic simulation represents an effective tool for evaluating the suggested alternatives to enhance traffic conditions prior to their application in real sites. U-turn sections represent examples of the complicated sections that cannot be analyzed properly without applying microsimulation approach. Recently, in Iraq, speed humps were applied in prior to the merging locations and U-turn sectio...
The mechanism by which psychostimulants act as calming agents in humans with attention-deficit hyperactivity disorder (ADHD) or hyperkinetic disorder is currently unknown. Mice lacking the gene encoding the plasma membrane dopamine transporter (DAT) have elevated dopaminergic tone and are hyperactive. This activity was exacerbated by exposure to a novel environment. Additionally, these mice wer...
Safety is one of the most important and complex aspects of transportation engineering. It takes a traffic professional considerable time and effort to keep abreast of research in the field of safety as it relates to traffic engineering improvements. Reading through research reports and summarizing the results is an overwhelming task; especially when having to identify the constraints of each st...
