Dear Editor: I read the article “Epilens membrane simulating cataract in children with uveitis: a report of three cases” by Paiva et al. with great interest. Three cases were presented that were diagnosed as cataract secondary to uveitis but that were understood to have received treatment for pupillary membrane intraoperatively. I congratulate the authors for their attention and good management...

OBJECTIVES Infections caused by Staphylococcus aureus might be treated with agents whose primary indications are for other infections. Clofazimine, an established anti-mycobacterial drug, could be such a candidate. However, the anti-staphylococcal properties of clofazimine have not been fully described and its mode of action, possibly involving inhibition of both RNA polymerase and a membrane-l...

We consider the design of a contest in which prize may motivate not only productive efforts, but also some damaging aggressive behavior by contestants. The organizer must choose prizes and an enforcement regime defined as limit on how much aggressiveness will be tolerated probability inspection. When value contestants’ output is low, it optimal to less effort than first best because spread nece...

Erythrocytes shed membrane vesicles in response to many stimuli. It has been previously demonstrated that glycan phosphatidylinositol-linked (GPI-linked) proteins such as decay accelerating factor and acetylcholinesterase are concentrated in these vesicles relative to the erythrocyte membrane. We have examined the requirement for GPI-linked proteins for the process of vesiculation. Erythrocytes...
