Polymers have been extensively utilized in the design of nanometer-sized delivery vehicles of chemotherapeutics for clinical cancer therapy. Polymeric nanoparticulate delivery vehicles, with chemotherapeutics being either conjugated or encapsulated,…
-
The entropy deficiencies of the Information Theory are used to measure the information 'distance' between the electron densities of the transition-state complex in collinear atom exchange reactions and the corresponding 'promolecular' densities…

The combination of branched DNA molecules and 'sticky' ends creates a powerful molecular assembly kit for structural DNA nanotechnology. Polyhedra, complex topological objects, a nanomechanical device and two-dimensional arrays with. programmable…
-
The interface between nanosystems and biosystems is emerging as one of the broadest and most dynamic areas of science and technology, bringing together biology, chemistry, physics, biotechnology, medicine, and many areas of engineering. The…
-
Methods based on self-assembly, self-organization, and forced shape transformations to form synthetic or semisynthetic enclosed lipid bilayer structures with several properties similar to biological nanocompartments are reviewed. The procedures…

MOTIVATION: The reconstruction of genetic networks is the holy grail of functional genomics. Its core task is to identify the causal structure of a gene network, that is, to distinguish direct from indirect regulatory interactions among gene…
-
The kinetic parameters for the combustion of carbonaceous residue or coke deposited on the sand during the fluidized bed pyrolysis of tar sands have been determined. Nonisothermal thermo- gravimetric experiments at a fixed heating rate were…

We review molecular dynamics simulations of nucleic acids, including those completed from 1995 to 2000, with a focus on the applications and results rather than the methods. After the introduction, which discusses recent advances in the simulation…
