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[...

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 ...

We present a system for extracting structured information from unstructured text using a combination of information retrieval, natural language processing, machine learning, and crowdsourcing. We test our pipeline by building a structured database of gun violence incidents in the United States. The results of our pilot study demonstrate that the proposed methodology is a viable way of collectin...

BACKGROUND National surveillance systems have differentiated long guns into rifles and shotguns but fail to do so for handgun type. We sought to determine whether specific gun type data could be collected and whether knowledge of specific gun types (rifle, shotgun, pistol, revolver) could be used to distinguish gun homicide victims with respect to important injury parameters such as number of w...

OBJECTIVE To determine gun storage practices in gun-owning households with children. DESIGN National random digit-dial telephone survey of 2521 households conducted in March 1999 through July 1999. This study uses a subsample of 434 households with children <18 years old in which a respondent reported either: 1) personally owning a gun, or 2) living in a gun-owning household but not owning a ...

Gun violence is a leading cause of premature deaths in the United States. Evidence has linked higher levels of firearm ownership to an increased risk for violent crimes perpetrated with a firearm. Given that connection, the goal of this study is to use mathematical modeling techniques to better understand how different social conditions may impact gun-ownership rate. To accomplish that goal, we...
