Predicting Fixation Tendencies of the H3N2 Influenza Virus by Free Energy Calculation [PDF]

open access: yesJ. Chem. Theory Comput. 7 (2011) 1259-1272, 2012
Influenza virus evolves to escape from immune system antibodies that bind to it. We used free energy calculations with Einstein crystals as reference states to calculate the difference of antibody binding free energy ($\Delta\Delta G$) induced by amino acid substitution at each position in epitope B of the H3N2 influenza hemagglutinin, the key target ...

The Factors of the Classification of Protein Amino Acids [PDF]

open access: yesThis paper is published in GLASNIK of Montenegrin Academy of Science and arts, 2000, 13, pp. 173-194, 2006
In this work it is shown that three pairs of the factors appear to be the key, i.e. main factors of a natural classification of protein (canonical) amino acids within the amino acid (genetic) code. First pair: the factors of the habit of an amino acid molecule (size and polarity).

A Highly Adaptable Hydrogen Bond Re‐Orientation (HyBRO) Strategy for Multiscale Vasculature Fabrication

open access: yesAdvanced Materials, EarlyView.
A novel hydrogen bond re‐orientation (HyBRO) strategy enables three‐dimensional (3D) printing of vascular microchannel networks with high accuracy. By switching sacrificial material interactions with nonsolvents, HyBRO prevents swelling and deformation, enabling accurate hierarchical channels spanning a tenfold size range.
