Gelamo et al., on page 331 of this issue, present the elegant work entitled “Effects of reprocessing on chemical and morphological properties of guide wires used in angioplasty” [1], in which they describe significant morphological changes after washing the guide wires once or twice using ultrasonic vibration and enzymatic detergent, and no significant changes when sterilized with ethylene oxid...

The ultraviolet spectral slope of individual Seyfert 1 galaxies and quasars, measured using IUE observations,varies considerablywith time. Neither accretiondisks nor opticallythin emission models can explain these variations. A superimposition of two components can easily solve the problem. We propose here a method based on the variability properties of these objects to disentangle various comp...

Eye Movement Desensitization and Reprocessing (EMDR) was one of the first treatments of posttraumatic stress disorder (PTSD) to be evaluated in controlled research and has to date been empirically supported by 13 such studies. This article reviews the historical context and empirical research of EMDR over the past dozen years. Historically, EMDR's name has caused confusion in that "desensitizat...
