BACKGROUND Techniques for better hemorrhage control after injury could change outcome. A large-animal model of lethal, uncontrolled hemorrhage was developed to test whether the use of various hemostatic agents would decrease bleeding and improve early survival. METHODS A complex groin injury was created in 30 Yorkshire swine (42-55 kg) to produce(More)
Traumatic injury to the adult human spinal cord most frequently occurs at the mid-to-low cervical segments and produces tetraplegia. To investigate treatments for improving upper extremity function after cervical spinal cord injury (SCI), three behavioral tests were examined for their potential usefulness in evaluating forelimb function in an adult rat(More)
BACKGROUND Rejuvenation of the midface with a natural-looking, safe, and long-lasting result is a challenge in aesthetic surgery. The ideal approach should be easy to perform, with minimal risk and significant benefit. The combination of transconjunctival exposure and preservation of the periosteum may result in lower morbidity than traditional midface(More)
BACKGROUND Resuscitation fluids can have variable effects on key functions of circulating polymorphonuclear neutrophils (PMNs) such as oxidative burst, chemotaxis, and bacterial killing. We hypothesized that choice of resuscitation fluids will also affect the rate of PMN apoptosis. To test this, we studied cellular death (apoptosis and necrosis) in human(More)
BACKGROUND In the morbidly obese patient undergoing laparoscopic gastric bypass (LGBP), insufflation with carbon dioxide to 20 mmHg for prolonged periods may induce significant hypercarbia and acidosis with attendant sequelae. We hypothesize that the use of helium as an insufflating agent results in less hypercarbia and acidosis. METHODS The study was(More)
