Physician staffed helicopter emergency medical systems can provide advanced trauma life support in mountainous and remote areas.

Introduction: In remote and mountainous areas, helicopter emergency medical systems (HEMS) are used to expedite evacuation and provide pre-hospital advanced trauma life support (ATLS) in major trauma victims. Aim of the study was to investigate feasibility of ATLS in HEMS mountain rescue missions and its influence on patient condition at hospital admission.

Patients: 58 major trauma victims (Injury Severity Score ≥16), evacuated by physician staffed HEMS from remote and mountainous areas in the State of Tyrol, Austria between 1.

Identification, cloning, and characterization of a multicomponent biphenyl dioxygenase from Sphingobium yanoikuyae B1.

Sphingobium yanoikuyae B1 utilizes both polycyclic aromatic hydrocarbons (biphenyl, naphthalene, and phenanthrene) and monocyclic aromatic hydrocarbons (toluene, m- and p-xylene) as its sole source of carbon and energy for growth. The majority of the genes for these intertwined monocyclic and polycyclic aromatic pathways are grouped together on a 39 kb fragment of chromosomal DNA. However, this gene cluster is missing several genes encoding essential enzymatic steps in the aromatic degradation pathway, most notably the genes encoding the oxygenase component of the initial polycyclic aromatic hydrocarbon (PAH) dioxygenase.

Toxin-antitoxin systems are ubiquitous and plasmid-encoded in vancomycin-resistant enterococci.

Vancomycin-resistant enterococci (VRE) are common hospital pathogens that are resistant to most major classes of antibiotics. The incidence of VRE is increasing rapidly, to the point where over one-quarter of enterococcal infections in intensive care units are now resistant to vancomycin. The exact mechanism by which VRE maintains its plasmid-encoded resistance genes is ill-defined, and novel targets for the treatment of VRE are lacking.
