Social Media in Nurse Anesthesia: A Model of a Reproducible Educational Podcast.

Social media and specifically podcasting are available to the field of nurse anesthesia as potential educational tools. This article outlines key concepts in social media, including free open access medical education and literature supporting the use of podcasting in higher, medical, and nursing education. The authors provide an educational model useful for developing social media tools and a logic model for producing an educational podcast.

Alterations of the oxygen-evolving apparatus in a (448)Arg --> (448)S mutant in the CP47 protein of photosystem II under normal and low chloride conditions.

We have shown previously that a mutant which contained the alteration (448)R --> (448)S (R448S) in the CP47 protein of photosystem II exhibited a defect in its ability to grow and assemble functional photosystem II reaction centers under chloride-limiting conditions [Wu, J., Masri, N., Lee, W.

Survival of Staphylococcus aureus inside neutrophils contributes to infection.

Neutrophils have long been regarded as essential for host defense against Staphylococcus aureus infection. However, survival of the pathogen inside various cells, including phagocytes, has been proposed as a mechanism for persistence of this microorganism in certain infections. Therefore, we investigated whether survival of the pathogen inside polymorphonuclear neutrophils (PMN) contributes to the pathogenesis of S.

Optical testing of condoms.

Condoms provide one of the most important means of preventing pregnancy and the spread of human immunodeficiency virus (HIV) and other sexually transmitted diseases. Pinhole defects may lead to the passage of sperm or viruses through the condom wall. Embedded particles, which may become dislodged in handling or use, may represent latent pinhole defects.

Spontaneous elaboration of transforming growth factor beta suppresses host defense against bacterial infection in autoimmune MRL/lpr mice.

Infection with gram-negative and gram-positive bacteria remains a leading cause of death in patients with systemic lupus erythematosis (SLE), even in the absence of immunosuppressive therapy. To elucidate the mechanisms that underly the increased risk of infection observed in patients with systemic autoimmunity, we have investigated host defense against bacterial infection in a murine model of autoimmunity, the MRL/Mp-lpr/lpr (MRL/lpr) mouse. Our previous study implicated transforming growth factor beta (TGF-beta) in a novel acquired defect in neutrophil function in MRL/lpr but not congenic MRL/Mp-+/+ (MRL/n) mice (Gresham, H.
