  • Computational chemistry and molecular modeling is a fast emerging area which is used for the modeling and simulation of small chemical and biological systems in order to understand and predict their behavior at the molecular level. It has a wide range of applications in various disciplines of engineering sciences, such as materials science, chemical engineering, biomedical engineering, etc.

  • Science progresses by a symbiotic interaction between theory and experiment: theory is used to interpret experimental results and may suggest new experiments; experiment helps to test theoretical predictions and may lead to improved theories. Theoretical Chemistry (including Physical Chemistry and Chemical Physics) provides the concep- tual and technical background and apparatus for the rationalisation of phenomena in the chemical sciences. It is, therefore, a wide ranging subject, reflecting the diversity of molecular and related species and processes arising in chemical systems.

  • A report on the Molecular Approaches to Malaria meeting, Lorne, Australia, 4-8 February 2004. species-specific genes are mainly involved in unique, species-specific processes of the parasites and thus are potential targets for antimalarial strategies. David Roos (University of Pennsylvania, Philadelphia, USA) introduced the updated version of the Plasmodium Genome Resource [], which includes the complete P. falciparum genome as well as the partial genome sequences of additional plasmodial...

  • Molecular dynamics (MD) simulations have played increasing roles in our understanding of physical and chemical processes of complex systems and in advancing science and technology. Over the past forty years, MD simulations have made great progress from developing sophisticated theories for treating complex systems to broadening applications to a wide range of scientific and technological fields. The chapters of Molecular Dynamics are a reflection of the most recent progress in the field of MD simulations....

  • Extent of knowledge sharing: Related to the above problem is the question of how much knowledge is available to the system during its query optimization process. In particular, the first step in choosing a query evaluation strategy is likely to be identifying which nodes have materialized views that can speed query processing. A simple technique would be to use a centralized catalog of all available views and their locations, analogous to the central directory used by Napster. Yet this model introduces a single point of failure and a potential scalability bottleneck.

  • It is often said that computers are revolutionizing science and engineering. By using computers we are able to construct complex engineering designs such as space shuttles. We are able to compute the properties of the universe as it was fractions of a second after the big bang. Our ambitions are ever-increasing. We want to create even more complex designs such as better spaceships, cars, medicines, computerized cellular phone systems, and the like. We want to understand deeper aspects of nature. These are just a few examples of computer-supported modeling and simulation.

  • Systems biology has received an ever increasing interest during the last decade. A large amount of third-party funding is spent on this topic, which involves quantitative experimentation integrated with computational modeling. Industrial companies are also starting to use this approach more and more often, especially in pharmaceutical research and biotechnology.

  • The coagulation and fibrinolytic systems are central to the hemostatic mechanism, which works promptly on vascular injury and tissue damage. The rapid response is generated by specific molecular interactions between components in these systems. Thus, the regulation mechanism of the sys-tems is programmed in each component, as exemplified by the elegant pro-cesses in zymogen activation.

  • Bacterial type IV secretion systems (T4SS) form supramolecular protein complexes that are capable of transporting DNA or protein substrates across the bacterial cell envelope and, in many cases, also across eukaryotic target cell membranes.

  • Type IV secretion systems (T4SS) are macromolecular assemblies used by bacteria to transport material across their membranes. T4SS are generally composed of a set of twelve proteins (VirB1–11 and VirD4). This repre-sents a dynamic machine powered by three ATPases.

  • A review of the regulatory framework can also provide some indication of the level of competition within a country’s banking system. Other things being equal, competition should be greater when regulatory barriers to entry and exit is low, encouraging new entrants. The regulatory framework for the EAC region, summarized in Table 1, suggests a relatively open regime with similar conditions of entry and prudential treatment for all types of banks across countries.

  • The galactose uptake mechanism in yeast is a well-studied regulatory net-work. The regulatory players in the galactose regulatory mechanism (GAL system) are conserved in Saccharomyces cerevisiae and Kluyveromyces lactis, but the molecular mechanisms that occur as a result of the molecular interactions between them are different.

  • Cytochromes of thec-type contain hemes covalently attached via one or, more generally, two thioether bonds between the vinyls of hemeband the thiols of cysteine residues of apocytochromes. This post-translational modi-fication relies on membrane-associated specific biogenesis proteins, referred to as cytochrome c maturation systems.

  • Neuropilin (NRP) and plexin (Plex) that are now known to be semaphorin receptors were initially identified as antigens for monoclonal antibodies (MAbs) that bound to particular neuropiles and plexiform layers of the Xenopus tadpole optic tectum, several years before the discovery of semaphorin. The extracellular segment of the NRP protein is a mosaic of 3 functionally different protein motifs that are thought to be involved in molecular and/or cellular interactions, suggesting that NRP serves in a various cell-cell interaction by binding a variety of molecules.
