What is the length of a knot in a polymer?
, 2005 We give statistical definitions of the length, l, of a loose prime knot tied
into a long, fluctuating ring macromolecule. Monte Carlo results for the
equilibrium, good solvent regime show that ~ N^t, where N is the ring
length and t ~ 0.75 is ...Marcone, B., Orlandini, E., Stella, A. L., Zonta, F. +3 morecore +1 more sourceAssessment of the genotoxicity of quinolone and fluoroquinolones contaminated soil with the Vicia faba micronucleus test [PDF]
, 2012 The genotoxicity of quinolone and fluroquinolones was assessed using the micronucleus (MN) test on Viciafaba roots by direct contact exposure to a solid matrix.Bousquet-Mélou, Alain, Guiresse, Agnès Maritchù, Hafidi, Mohamed, Hamdi, Hassan, Khadra, Ahmed, Lacroix, Marlene Z., Merlina, Georges, Pinelli, Eric +7 morecore +3 more sourcesMechanically Triggered DNA Nanovehicles for Targeted Dual‐Drug Cancer Therapy
Advanced Science, EarlyView.A mechanically triggered DNA nanovehicle is introduced that co‐releases two anticancer drugs in response to integrin‐mediated cellular forces. Cholesterol‐anchored DNA assemblies undergo force‐induced unfolding at cell–cell junctions, enabling selective, localized dual‐drug activation in cancer cells while minimizing off‐target toxicity in low‐tension ...Murali Mohana Rao Singuru, Priyanka Bhattacharyya, Mingxu You +2 morewiley +1 more sourceRole of Supercoiling and Topoisomerases in DNA Knotting
DNADNA knots are deleterious for living cells if not removed. Several theoretical and simulation approaches address the question of how topoisomerases select the intermolecular passages that preferentially lead to unknotting rather than to the knotting of ...Jorge Cebrián, María-Luisa Martínez-Robles, Victor Martínez, Pablo Hernández, Dora B.

Molecules, 2020 Topoisomerases in the type IA subfamily can catalyze change in topology for both DNA and RNA substrates. A type IA topoisomerase may have been present in a last universal common ancestor (LUCA) with an RNA genome.Tumpa Dasgupta, Shomita Ferdous, Yuk-Ching Tse-Dinh +2 moredoaj +1 more sourceMutations in topoisomerase IIβ result in a B cell immunodeficiency.
