2-amino-5-chloropyrimidin-1-ium hydrogen maleate by Fun, Hoong-Kun., Hemamalini, Madhukar., Rajakannan, Venkatachalam.

“…In the roughly planar (r.m.s. deviation = 0.026 Å) hydrogen malate anion, an intramolecular O-HO hydrogen bond generates an S(7) ring. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxylate O atoms of the anion via a pair of N-HO hydrogen bonds, forming an R22(8) ring motif. …”

Is there a role for traction forces exerted at the polar regions in the cytokinesis of adherent cells? by Foo, Jasmine Mao Shan.

“…In cytokinesis, the division of the cytoplasm of the mother cell to form two daughter cells has long been known to be accomplished by furrow ingression through constriction of the contractile ring. Recent studies suggested that adherent cells could divide without the contractile ring, in an adhesion-dependent manner by producing traction forces. …”

Molecular architecture of the Chikungunya virus replication complex by Tan, Yaw Bia, Chmielewski, David, Law, Michelle Cheok Yien, Zhang, Kuo, He, Yu, Chen, Muyuan, Jin, Jing, Luo, Dahai

“…Within the core RNA replicase, the viral polymerase nsP4, which is in complex with nsP2 helicase-protease, sits in the central pore of the membrane-anchored nsP1 RNA-capping ring. The addition of a large cytoplasmic ring next to the C terminus of nsP1 forms the holo-RNA-RC as observed at the neck of spherules formed in virus-infected cells. …”

Polar curved polycyclic aromatic hydrocarbons in soot formation by Menon, Angiras, Martin, Jacob W., Bowal, Kimberly, Slavchov, Radomir I., Akroyd, Jethro, Mosbach, Sebastian, Kraft, Markus

“…The earliest (smallest size) onset of curvature integration was found to be a six ring PAH with at least one pentagonal ring. The σ bonding in the presence of pentagons led to curvature, however, the π bonding strongly favored a planar geometry delaying the onset of curvature and therefore the induction of a flexoelectric dipole moment. …”
