We present an experimental investigation of the mechanisms that can be used to control blunt-end induced effective attractions between densely packed spherical double-stranded DNA (dsDNA) brushes. Using microscopy and particle tracking, we determine effects varying parameters controlling brush dsDNA fragment conformation, in particular functionality, salinity, length. The analysis structure dyn...

BACKGROUND AND PURPOSE There are no standard screening guidelines to evaluate blunt cerebrovascular injury in children. The purpose of this retrospective study was to understand the clinical and radiologic risk factors associated with pediatric blunt cerebrovascular injury on CTA of the neck with primary attention to the cervical "seatbelt sign." MATERIALS AND METHODS Radiology reports from 2...

Over the past decade, the recognition and subsequent management of blunt cerebrovascular injuries has undergone a marked evolution. Originally thought to be a rare occurrence, blunt cerebrovascular injuries are now diagnosed in approximately 1% of blunt trauma patients. The recognition of a clinically silent period allows for angiographic screening for injuries based upon the mechanism of traum...

the majority of blunt trauma is secondary to motor vehicle crashes,especially in those wearing seatbelts or sitting in the front or passenger seat location.hollow viscus gastrointestinal injuries occur more frequently in small bowel, followed by colorectal, duodenum, stomach and appendix. a 25-year-old male presents after being involved in a motor vehicle accident. initialworkup was significant...

introduction: management of pediatric blunt abdominal trauma in resource-restricted settings requires precise clinical expertise. in this study, we reviewed pediatric patients who were suspected to have blunt abdominal trauma in a level iii trauma center in iran. materials and methods: in a cross-sectional study, 66 injured children were studied from october 01, 2014 to october 01, 2015 in niks...

conclusions it seems that fast examination for intra-abdominal fluid in blunt trauma patients can predict intra-abdominal injuries with very high sensitivity and specificity. using the scoring system can more accurately determine the probability of the presence of abdominal injuries with a cut-off point of three. results the mean age of the patients was 29.6 ± 18.3 years and fast was positive i...
