An increased appreciation of the importance of transporter and enzyme interplay in drug clearance and a desire to delineate these mechanisms necessitates the utilization of models that contain a full complement of enzymes and transporters at physiologically relevant activities. Additionally, the development of drugs with longer half-lives requires in vitro systems with extended incubation times...

Miró: Visual Specification of Security

Miro is a set of languages and tools that support visual specification of file system security. We describe two visual languages: the instance language which allows specification of file system access, and the constraint language which allows specification of security policies. We present the syntax and semantics of these languages, and discuss some novel algorithms that efficiently check for p...

Determining direct synaptic connections of specific neurons in the central nervous system (CNS) is a major technical challenge in neuroscience. As a corollary, molecular pathways controlling developmental synaptogenesis in vivo remain difficult to address. Here, we present genetic tools for efficient and versatile labeling of organelles, cytoskeletal components and proteins at single-neuron and...
