pretest probability of moderate to severe obstructive sleep apnea.6 A randomized control study is a well-designed clinical trial to examine clinical problems.7 However, our study was a prospective but not a randomized trial and was performed in a single center with a small number of patients. We agree that a study with a better design and larger sample size may solve the issues raised. Finally,...

Current assays for screening new antimalarials need initiators of beta-hematin formation that require laborious preparation, special devices, and substrates. In this study, based on reduction of heme absorption in beta-hematin formation, we developed a simple colorimetric assay using Tween 20 as an initiator and a microplate reader for high-throughput screening of inhibitors of beta-hematin for...

Central to a new, or 'resolute', reading of Wittgenstein's Tractatus LogicoPhilosophicus is the idea that Wittgenstein held there an 'austere' view of nonsense: the view, that is, that nonsense is only ever a matter of our failure to give words a meaning, and so that there are no logically distinct kinds of nonsense.
