A ceramographic evaluation of chromia refractories corroded by slag

This paper describes the ceramographic preparation of Cr{sub 2}O{sub 3}-Al{sub 2}O{sub 3} refractory bricks and subsequent microstructural analysis to determine the corrosive effects of molten slag. The porous and friable nature of the brick, especially after exposure to the slag or its individual components, presented some problems in the preparation

Adoption of the 2006 Field Triage Decision Scheme for Injured Patients

Background: When emergency medical services (EMS) providers respond to the scene of an injury, they must decide where to transport the injured patients for further evaluation and treatment. This is done through a process known as “field triage”, whereby a patient’s injuries are matched to the most appropriate hospital. In 2005-2006 the National Expert Panel on Field Triage, convened by the Centers for Disease Control and Prevention and the National Highway Traffic Safety Administration, revised the 1999 American College of Surgeons Committee on Trauma Field Triage Decision Scheme. This revision, the 2006 Field Triage Decision Scheme, was published in 2006.Methods: State Public Health departments’ and EMS’ external websites were evaluated to ascertain the current status of implementation of the 2006 Field Triage Decision Scheme.Results: Information regarding field triage was located for 41 states. In nine states no information regarding field triage was available on their websites. Of the 41 states where information was located, seven were classified as “full adopters” of the 2006 Field Triage Decision Scheme; nine were considered “partial adopters”; 17 states were found to be using a full version or modification of the 1999 Field Triage Decision Scheme; and eight states were considered to be using a different protocol or scheme for field triage.Conclusion: Many states have adopted the 2006 Decision Scheme (full or partial). Further investigation is needed to determine the reasons why some states do not adopt the guidelines. [West J Emerg Med. 2011;12(3):275-283.

Macrophage Migration Inhibitory Factor Mediates Protease-Activated Receptor 4-Induced Bladder Pain Through Urothelial High Mobility Group Box 1

Macrophage migration inhibitory factor (MIF) mediates pain although the mechanisms are not well understood. Urothelial activation of protease activated receptor 4 (PAR4) results in urothelial MIF release, urothelial high mobility group box 1 (HMGB1) release and bladder pain in mice without bladder inflammation. All three effects are prevented by MIF inhibition while intravesical disulfide HMGB1 alone can induce bladder pain. This study utilizes genetic MIF deletion to determine whether MIF mediates PAR4-induced bladder pain and is upstream of HMGB1-induced bladder pain. Wild type (C57/BL6) and MIF knockout (KO) mice were treated with intravesical PAR4 activating peptide or disulfide HMGB1 and tested for abdominal mechanical hypersensitivity at baseline (before treatment) and 24 h after injection. Micturition parameters and bladder histology were examined after behavioral test. Real-time PCR and western blotting measured HMGB1 mRNA and protein levels in the bladders of naïve wild type and MIF KO mice, while immunofluorescence measured HMGB1 protein levels in the urothelium of both strains. Intravesical PAR4 activation resulted in abdominal mechanical hypersensitivity in wild-type mice but not MIF KO mice. Intravesical disulfide HMGB1 induced abdominal mechanical hypersensitivity in both strains. Neither treatment resulted in significant changes in micturition or bladder histology in either strain. HMGB1 mRNA and protein levels were higher in MIF KO mouse bladders and the urothelium of MIF KO bladder had greater immunostaining than the wild-type strain. MIF is a pivotal molecule mediating PAR4-induced bladder pain and regulating urothelial HMGB1 production and release to elicit bladder pain
