Autophagy is an intracellular recycling and degradation process, which is important for energy metabolism, lipid metabolism, physiological stress response and organism development. During Drosophila development, autophagy is up-regulated in fat body and midgut cells, to control metabolic function and to enable tissue remodelling. Atg9 is the only transmembrane protein involved in the core autop...

This study examines the impact on student achievement of implementing a bundle of best practices from high-performing charter schools into lowperforming, traditional public schools in Houston, Texas, using a school-level randomized field experiment and quasi-experimental comparisons. The five practices in the bundle are increased instructional time, more effective teachers and administrators, h...

Three naphthoquinone derivatives (plumbagin, juglone, and menadione) have been reported with antibacterial, antifungal, and antiviral properties and could potentially be used as anticancer agents because they can provoke apoptosis. However, they are also strong oxidants and cause cytotoxicity and even necrosis, so they are only limited to experimental chemotherapeutic use. In order to understan...

Embedding of N5 and the contiguous degrees

Downey and Lempp 8] have shown that the contiguous computably enumerable (c.e.) degrees, i.e. the c.e. Turing degrees containing only one c.e. weak truth-table degree, can be characterized by a local distributivity property. Here we extend their result by showing that a c.e. degree a is noncontiguous if and only if there is an embedding of the nonmodular 5-element lattice N5 into the c.e. degre...
