Background Gun shows are an important source of firearms, but no adequately powered studies have examined whether they are associated with increases in firearm injuries. Objective To determine whether gun shows are associated with short-term increases in local firearm injuries and whether this association differs by the state in which the gun show is held. Design Quasi-experimental. Setti...

We have isolated a variant of human immunodeficiency virus type 1 (HIV-1) which is highly infectious to fibroblastlike cells (BT cells) derived from human brain as well as CD4-positive T cells. This variant HIV-1, named HIV[GUN-1V], was obtained by infecting BT cells with a prototype HIV-1 isolate, named HIV[GUN-1WT], which is highly infectious to T cells but barely infectious to BT cells. HIV[...

purpose: to report the first case of concomitant optic nerve transection and chorioretinitis sclopetaria patient and findings: a 12-year-old boy with history of bb gun injury to his right eye was referred for loss of vision 8 months after the accident. visual acuity in the right eye was counting fingers at one meter with 3+ rapd. on slit lamp examination, right eye seemed normal except 1+ anter...

We describe an innovative aspirator gun designed to transfer individual anesthetized mosquitoes directly into glass bioassay tubes. The gun has been used for thousands of transfers with extremely low associated mortality and is the central component of a high-throughput bioassay system. The gun is constructed using readily obtainable materials and can be modified for a range of insects.

BACKGROUND An estimated 3700 individuals are seen annually in US emergency departments for nail gun-related injuries. Approximately 45 cases have been reported in the literature concerning nail gun injuries penetrating the cranium. These cases pose a challenge for the neurosurgeon because of the uniqueness of each case, the dynamics of high pressure nail gun injuries, and the surgical planning ...

The objective of this study was to determine the accessibility of firearms, methods of firearm access and firearm safety knowledge among middle and high school students in Orange County, California. METHODS After permission from school officials and parents was obtained, a 24-question sur...

Nowadays, the investigation of both classic and new materials for blast mitigation applications is a subject intensively approached in scientific literature. Due to their mechanical behavior, polyurethane foams are with high potential this type applications. Within current paper EUROPLASTIC� foam grade mixed fly ash ceramic micro powder was experimentally investigated. Using single stage gas gu...

Gun violence is a major cause of preventable injury and death in the United States, leading to more than 33,000 deaths each year. However, gun violence prevention is an understudied and underfunded area of research. We review the barriers to research in the field, including restrictions on federal funding. We then outline potential areas in which further research could inform clinical practice,...
