The effect of location and configuration on forearm and upper arm hemodialysis arteriovenous grafts.

Objective: The arteriovenous graft (AVG) is most often used in hemodialysis patients when an autogenous fistula is not feasible. The optimal location (forearm or upper arm) and configuration (loop or straight) of AVGs are not known. To evaluate relationships of AVG location and configuration with patency, we conducted a secondary analysis using data from a randomized, placebo-controlled trial of dipyridamole plus aspirin for newly placed AVG.

96-hour methamphetamine self-administration in male and female rats: a novel model of human methamphetamine addiction.

Methamphetamine (MA) is a highly addictive psychostimulant drug of abuse for which no FDA-approved treatment exists. While high on MA, both male and female MA users report engaging in risky behaviors and are more likely to be involved in violent criminal activities and to engage in domestic and sexual violence. A unique aspect of MA is that it is typically used in binges.

Selectin blockade decreases postischemic recruitment of bone marrow stromal cells.

Objectives/hypothesis: Investigate the localization mechanisms of bone marrow stromal cells following transient ischemia-reperfusion injury in a murine flap model.
