The mol-ecular conformation of the title compound, C(28)H(21)ClN(2), is stabilized by an intra-molecular C-H⋯N hydrogen bond. It has many pharmacological properties, such as being an inhibitor of P38 MAP Kinase, and can play an important role in biochemical processes.

In order to produce specific complex structures from a large set of similar biochemical building blocks, many biochemical systems require high sensitivity to small molecular differences. The first and most common model used to explain this high specificity is kinetic proofreading, which has been extended to a variety of systems from detection of DNA mismatch to cell signaling processes. While t...

The purpose of this symposium was to examine how foraging physiology is studied in the field across a diversity of species and habitats. While field studies are constrained by the relatively poor ability to control the experiment, the natural variability in both the environment and animal behavior provides insights into adaptation to change that are usually not tested in the laboratory. Talks i...

Tracer technology makes it possible to observe physiological and biochemical processes in the living organism in a dynamic mode. Positron emission tomography adds the use of chemically unchanged biomolecules and of quantification. This opens up fascinating possibilities for both fundamental research and routine diagnostic applications.

Protein hydration shell dynamics play an important role in biochemical processes including protein folding, enzyme function, and molecular recognition. We present here a comparison of the reorientation dynamics of individual water molecules within the hydration shell of a series of globular proteins: acetylcholinesterase, subtilisin Carlsberg, lysozyme, and ubiquitin. Molecular dynamics simulat...

Sequence-specific protein–DNA binding is a process fundamental to life on earth. From the identification of replication sites on the chromosome to the differential expression of genes during development, a multitude of sequence-specific DNA-binding proteins regulate the fundamental biochemical processes of life. Understanding how these different proteins are able to find and bind selectively to...

The biochemical processes that determine the lifespan of mammalian erythrocytes are unknown; one prominent theory suggests that antibody binding to the senescent red blood cell identifies it for removal from the circulation. To address this question, we have used a newly developed procedure for the isolation of aged erythrocytes that involves the biotinylation of rabbit red blood cells, in vivo...

Molecular motions, including both protein and RNA, play an essential role in many biochemical processes. Simulations have attempted to study these detailed large-scale molecular motions, but they are often limited by the expense of representing complex molecular structures. For example, enumerating all possible RNA conformations with valid contacts is an exponential endeavor, and the complexity...

Polymerization of proteins is a biochemical process involved in different diseases. Mathematically, it is generally modeled by aggregation-fragmentation-type equations. In this paper we consider a general polymerization model and propose a high-order numerical scheme to investigate the behavior of the solution. An important property of the equation is the mass conservation. The fifth-order WENO...
