The focal uptake by human atherosclerotic lesions of 125I bound to low density lipoproteins (LDL) can be demonstrated by external imaging. However, 125I has poor imaging characteristics. Therefore, we have developed a technique for labeling LDL with technetium. To facilitate analysis, LDL was first labeled with 99mTc, by reduction of TcO4- with dithionite(More)
A patient had severe hydrocephalus and diffuse leptomeningeal enhancement on MR which mimicked leptomeningeal spread of a primary brain tumor. The leptomeningeal enhancement resolved completely after decompression of the hydrocephalus. Data suggest that the leptomeningeal enhancement is caused by vascular stasis induced by the hydrocephalus.
BACKGROUND The Accreditation Council for Graduate Medical Education (ACGME) and the American Board of Pediatrics (ABP) have partnered to initiate the Pediatrics Milestone Project to further refine the 6 ACGME competencies and to set performance standards as part of the continued commitment to document outcomes of training and program effectiveness.

In December 2008, the Institute of Medicine published new recommendations regarding duty hours and supervision of residents' training in the United States. These recommendations evoked immediate concerns from program directors and leadership in all surgical and medical disciplines, including pediatrics. To address these concerns, the Accreditation Council(More)
The ultimate goal of graduate medical education has often been described as supporting learners in the pursuit of independent practice. To achieve this goal, learners and supervisors attempt to balance autonomy vs supervision, defining autonomy as allowing a learner to make decisions in the absence of a supervisor, and supervision as ensuring that ultimate(More)
PURPOSE Factors that support self-efficacy in family-centered care (FCC) must be understood in order to foster FCC in trainees. Using social cognitive theory, the authors examined (1) how three supportive experiences (observing role models, practicing for mastery, and receiving feedback) influence self-efficacy with FCC during rounds and (2) whether the(More)
In the September 2010 issue of JGME, the Pediatric Milestones Working Group published "The Pediatrics Milestones: Conceptual Framework, Guiding Principles, and Approach to Development", a document that describes the construction of the first iteration of the Pediatric Milestones. These Milestones were developed by the Working Group as a group of practical(More)
Helium nanodroplet isolation has been applied to agglomerate alkali clusters at temperatures of 380 mK. The very weak binding to the surface of the droplets allows a selection of only weakly bound, high-spin states. Here we show that larger clusters of alkali atoms in high-spin states can be formed. The lack of strong bonds from pairing electrons makes(More)
