We report the characterization of multifunctional rigid-rod beta-barrel ion channels with either internal aspartates or arginine-histidine dyads by planar bilayer conductance experiments. Barrels with internal aspartates form cation selective, large, unstable and ohmic barrel-stave (rather than toroidal) pores; addition of magnesium cations nearly deletes cation selectivity and increases single...

A bstract. Amongst modellers of natural language comprehension, the suspicion that explicit semantic representations are inherently biased has led many to rely more heavily on the ability of networks to form their own internal semantic representations over the course of training. The concern over explicit semantics, however, betrays a lack of appreciation for the manner in which insidious biase...

BACKGROUND With advances in mobile technology, accessibility of clinical resources at the point of care has increased. OBJECTIVE The objective of this research was to identify if six selected mobile point-of-care tools meet the needs of clinicians in internal medicine. Point-of-care tools were evaluated for breadth of coverage, ease of use, and quality. METHODS Six point-of-care tools were ...

PURPOSE To test the validity and reliability of a new tool for assessing residents' competence in ophthalmic surgery. Changing paradigms of ophthalmic education in the United States have influenced worldwide ophthalmic education and necessitated new methods of assessing resident competence. Accordingly, a new tool for assessing residents' competence in ophthalmic surgery (phacoemulsification) t...
