Self-expanding hemostatic polymer for control of exsanguinating extremity bleeding.

Background: Prehospital management of exsanguinating extremity injuries (EEI) includes direct compression or tourniquets or both. Direct compression may be ineffective in deep wounds and requires a person committed to compressing. Tourniquets may cause severe ischemic damage and may be ineffective in proximal wounds.

Space Station Biological Research Project (SSBRP) Cell Culture Unit (CCU) and incubator for International Space Station (ISS) cell culture experiments.

The CCU and Incubator are habitats under development by SSBRP for gravitational biology research on ISS. They will accommodate multiple specimen types and reside in either Habitat Holding Racks, or the Centrifuge Rotor, which provides selectable gravity levels of up to 2 g. The CCU can support multiple Cell Specimen Chambers, CSCs (18, 9 or 6 CSCs; 3, 10 or 30 mL in volume, respectively).

[Isolated dietary counselling program versus supplement and dietary counselling in patients with human immunodeficiency virus infection].

Background And Objective: Nutritional intervention is a controversial area. The aim of the study was to compare the influence on nutritional status of nutritional supplementation with a standard polymeric formula as well as nutritional counselling versus isolated nutritional counselling in a group of HIV-infected patients.

Patients And Method: There were 70 patients, 66 of whom were fully evaluated for each study end point after application of prospectively determined evaluability criteria.

Microgravity studies of cells and tissues.

Controlled in vitro studies of cells and tissues under the conditions of microgravity (simulated on Earth, or actual in space) can improve our understanding of gravity sensing, transduction, and responses in living cells and tissues. This paper discusses the scientific results and practical implications of three NASA-related biotechnology projects: ground and space studies of microgravity tissue engineering (JSC-Houston), and the development of the cell culture unit for use aboard the International Space Station (ARC-Ames).
