Self-Assembly of V-Shaped Polyaromatic Amphiphiles Studied by Molecular Dynamics Simulation.

V-shaped polyaromatic amphiphiles (s) form micelle-like nonbonded self-assemblies in aqueous solution and feature prominent properties of encapsulation and solubilization for various types of hydrophobic molecules. To understand microscopic molecular characteristics underlying the wide capability of solubilization, the atomic-level molecular structures of the self-assemblies of s were investigated by microsecond molecular dynamics (MD) simulations. The MD simulations showed that s spontaneously formed quasi-stable self-assemblies, in close agreement with experimental observations.

Voluntary intake of non-caloric sweetener drives conditioned bottle-position preference in mice.

The present study investigated whether saccharin, a non-caloric sweetener, induces conditioned bottle-position preference in mice. In a two-bottle preference test, the mice initially preferred water from a specific side. When saccharin was introduced on the opposite side, the mice showed increased total intake and a preference for the position of the saccharin bottle.

Case report: Duplication of the gene is a novel cause of nesidioblastosis: evidence from a case with Silver-Russell syndrome-like phenotype related to chromosome 7.

Silver-Russell syndrome (SRS) is a syndrome characterized by prenatal and postnatal growth retardation, facial features, and body asymmetry. SRS is often complicated with hypoglycemia, whose etiology is unclear. We describe the clinical course of 25-year-old man with hypoglycemia.
