Size Segregation and Convection of Granular Mixtures Almost Completely Packed in the Rotating Thin Box
Size segregation of granular mixtures which are almost completely packed in a
rotating drum is discussed with an effective simulation and a brief analysis.
Instead of a 3D drum, we simulate 2D rotating thin box which is almost
completely packed with granular mixtures. The phase inversion of radially
segregated pattern which was found in a 3D experiment are qualitatively
reproduced with this simulation, and a brief analysis is followed. Moreover in
our simulation, a global convection appears after radial segregation pattern is
formed, and this convection induces axially segregated pattern.Comment: 9 pages, 5 figures, PACS number(s): 45.70.-n, 45.70.M
PDZ domains and their binding partners: structure, specificity, and modification
PDZ domains are abundant protein interaction modules that often recognize short amino acid motifs at the C-termini of target proteins. They regulate multiple biological processes such as transport, ion channel signaling, and other signal transduction systems. This review discusses the structural characterization of PDZ domains and the use of recently emerging technologies such as proteomic arrays and peptide libraries to study the binding properties of PDZ-mediated interactions. Regulatory mechanisms responsible for PDZ-mediated interactions, such as phosphorylation in the PDZ ligands or PDZ domains, are also discussed. A better understanding of PDZ protein-protein interaction networks and regulatory mechanisms will improve our knowledge of many cellular and biological processes

Recording P2X Receptors Using Whole-Cell Patch Clamp from Native Monocytes and Macrophages
Investigating ion channels in their native cell type is important when striving to understand their regulation and function, but this comes with added complexities due to the plethora of channels and receptors present. Details of recording ATP-gated ion channels in macrophages are presented together with information on how to prepare the primary cells for electrophysiological analysis
