BACKGROUND: To increase the effectiveness of insecticide-treated nets (ITN) in areas of high resistance, new long-lasting insecticidal nets (LLINs) called new-generation nets have been developed. These nets are treated with the piperonyl butoxide (PBO) synergist which inhibit the action of detoxification enzymes. The effectiveness of the new-generation nets has been proven in some studies, but their specific effect on mosquitoes carrying detoxification enzymes and those carrying both detoxification enzymes and the knock-down resistance gene in Benin is not well known...

OBJECTIVES: Guided bone regeneration (GBR) aims to predictably restore missing bone that has been lost due to trauma, periodontal disease or a variety of systemic conditions. Critical to this procedure is the ability of a bone grafting material to predictably serve as a 3-dimensional scaffold capable of inducing cell and bone tissue in-growth at the material surface. Although all bone grafts are osteoconductive to bone-forming osteoblasts, only a small number of commercially available bone grafts with FDA approval are osteoinductive including demineralized freeze-dried bone allographs (DFDBA) and scaffolds containing bone morphogenetic proteins (BMPs)...

BACKGROUND: An investigation carried out in Benin has shown that, in some areas close to rivers where density of mosquitoes is high, long-lasting, insecticidal bed nets (LLINs) are permanently used. In such areas, LLINs are washed every month. Based on this situation, the 20-wash minimum efficacy advised by the manufacturers would be inadequate. The main goal of this study was to evaluate the effectiveness of LifeNet®, Olyset® and Permanet® 2.0 washed several times against Anopheles gambiae sensu stricto (s...

INTRODUCTION: Tissue transplantation is an important adjunct to modern medical care and is used daily to save or improve patient lives. Tissue allografts include bone, tendon, corneas, heart valves and others. Increasing utilization may lead to tissue shortages, and tissue procurement organizations continue to explore ways to expand the cadaveric donor pool. Currently more than half of all deaths occur outside the acute care setting. HYPOTHESIS: Many who suffer prehospital deaths might be eligible for non-organ tissue donation...

PURPOSE: Numerous surgical techniques have been described for the treatment of chronic scapholunate ligament instability. We hypothesized that scapholunate ligament reconstruction using an acellular dermal matrix was biomechanically comparable to previously described surgical reconstructions. METHODS: The scaphoid and lunate with the entire scapholunate ligament were harvested from 15 cadaveric specimens. The scapholunate ligament was transected and reconstructed using an acellular dermal matrix (Arthroflex; LifeNet Health, Virginia Beach, VA) and 4 micro suture anchors in 10 specimens...

PURPOSE: Indian healthcare is in the process of offering a plethora of services to customers hailing largely from India and from neighboring countries. The Indian hospital sector consists of private "nursing homes" and government and charitable missionary hospitals. Government and missionary hospitals determine their charges according to patients' income levels and treat poor patients freely. Nursing homes charged higher, market-determined rates. They offer services in just a few medical specialties, owned and operated by physicians who worked with them...

Although unprepared for a disaster of the magnitude of September 11th, New York City's mental health system responded immediately. Within weeks, Project Liberty, a recovery program funded by the Federal Emergency Management Agency (FEMA), was in operation. The program provides free education, outreach, and crisis counseling services for those affected by the disaster and its aftermath. LifeNet, a 24-hour, 7-day-a-week mental health information and referral hotline, is a key component of Project Liberty. In this article, we describe the operation of LifeNet and examine the volume of calls to the hotline during the 6 months following the terrorist attacks on the World Trade Center...
