    Notes: [Auszug] It remains unclear how and why autoimmunity occurs. Here we show evidence for a previously unrecognized and possibly general mechanism of autoimmunity. This new finding was discovered serendipitously using material from patients with inflammatory vascular disease caused by antineutrophil ...

    Notes: Abstract One of the most important characteristics of Quantitative Structure ActivityRelashionships (QSAR) models is their predictive power. The latter can bedefined as the ability of a model to predict accurately the target property(e.g., biological activity) of compounds that were not used for model development.We suggest that this goal can be achieved by rational division of an experimentalSAR dataset into the training and test set, which are used for model developmentand validation, respectively. Given that all compounds are represented by pointsin multidimensional descriptor space, we argue that training and test sets mustsatisfy the following criteria: (i) Representative points of the test set must beclose to those of the training set; (ii) Representative points of the training setmust be close to representative points of the test set; (iii) Training set must bediverse. For quantitative description of these criteria, we use molecular datasetdiversity indices introduced recently (Golbraikh, A., J. Chem. Inf. Comput. Sci.,40 (2000) 414–425). For rational division of a dataset into the training and testsets, we use three closely related sphere-exclusion algorithms. Using severalexperimental datasets, we demonstrate that QSAR models built and validated withour approach have statistically better predictive power than models generated witheither random or activity ranking based selection of the training andtest sets.We suggest that rational approaches to the selection of training andtest setsbased on diversity principles should be used routinely in all QSAR modelingresearch.

    Notes: Using molecular dynamics simulations to calculate free energies of molecular transformation, we have computed helix-coil transition free energies for alanine oligomers up to 14 residues long. The simulations have been done on the model in vacuo with dielectric constant, ε = 1, 5, 25, and ∞ and on the model in solution with explicit representation of water molecules and with partial charges on the oligomer set to zero. (The analogous simulations of the solvated model with full charges on the oligomer were reported elsewhere [L. Wang et al. (1995) Proceedings of the National Academy of Science USA 92, 10924-10928]). In vacuo, both entropic and electrostatic contributions oppose formation of a 3-residue helical nucleus in the helix initiation step. The entropy change opposing helix growth is found to be 3 e.u., van der Waals interactions favor helix growth by 1.9 kcal/mol, and electrostatic interactions favor helix growth by 3 kcal/mol (for ε = 1; all these values are per residue). In water, helix stability is slightly greater for the zero-charge model than for the full-charge model, i.e., the polypeptide's electrostatic interactions, which include hydrogen bonds, slightly destabilize the helix. The helix stabilizing contribution of the hydrophobic effect was found to be identical to that of the van der Waals interactions in vacuo (i.e., 1.9 kcal/mol per residue). The zero-charge model has nearly identical helix stability in vacuo and in water; the almost identical free energies of transfer of helix and coil state of the zero-charge oligomer from vacuum to water are found to be small. Thus, the results of this systematic variation of the force field afford a meaningful decomposition of the free energies for helix initiation and growth. © 1996 John Wiley & Sons, Inc.
