Results from scenario observations and post-scenario interviews with risk managers highlight the limitations of GIS for real-time(More)
We describe the isolation of a new class 2 restriction endonuclease from Providencia stuartii 164. Using the procedure of osmotic shock treatment, we have partially purified this enzyme (Pst 1) and have begun preliminary work to characterize its specificity and requirements. Pst 1 requires Mg++ as the only cofactor and produces more than 18 cleavages in(More)
The aim of the present study was to characterize the volatile metabolites produced by genotypically diverse strains of the Stenotrophomonas genus in order to evaluate their potential as biomarkers of lung infection by non-invasive breath analysis. Volatile organic compounds (VOCs) emitted from 15 clinical and five environmental strains belonging to(More)

BACKGROUND Mucous membrane pemphigoid (MMP), also known as cicatricial pemphigoid, is a serious, autoimmune, blistering disorder that can result in blindness and other complications as a result of scarring of the mucous membranes. Effective treatment modalities are often toxic. Herein, we describe a novel therapeutic approach that is based on 2 reports in(More)
The introduction of a number of biologic therapies into the market has revolutionized the practice of dermatology. These therapies include interferons, intravenous immunoglobulin, infliximab, adalimumab, etanercept, efalizumab, alefacept, and rituximab. Most dermatologists are familiar with the Food and Drug Administration-approved indications of these(More)
