Altered copy number of certain highly repetitive regions of the genome, such as satellite DNA within heterochromatin and ribosomal RNA loci (rDNA), is hypothesized to help safeguard the genome against damage derived from external stressors. We quantified copy number of the 18S rDNA and a pericentromeric satellite DNA (Msat-160) in bank voles (Myodes glareolus) inhabiting the Chernobyl Exclusion Zone (CEZ), an area that is contaminated by radionuclides and where organisms are exposed to elevated levels...

Supramolecular Storage and Controlled Photorelease of an Oxidizing Agent using a Bambusuril Macrocycle

Edoardo Torti, Václav Havel, Mirza A. Yawer, Lucie Ludvíková, Michal Babiak, Petr Klán & Vladimir Sindelar
Abstract The oxidizing ability of peroxodisulfate upon complexation inside the Bambusuril macrocycle cavity is inhibited. This dianionic agent can be released on demand from its stable 1:1 complex ...

Bambusuril as a One-Electron Donor for Photoinduced Electron Transfer to Methyl Viologen in Mixed Crystals

Tomas Fiala, Lucie Ludvíková, Dominik Heger, Jan Švec, Tomáš Slanina, L’ubica Vetráková, Michal Babiak, Marek Nečas, Petr Kulhánek, Petr Klán & Vladimir Sindelar
Methyl viologen hexafluorophosphate (MV2+·2PF6–) and dodecamethylbambus[6]uril (BU6) form crystals in which the layers of viologen dications alternate with those of a 1:2 supramolecular complex of BU6 and PF6–. This arrangement allows for a one-electron reduction of MV2+ ions upon UV irradiation to form MV+• radical cations within the crystal structure with half-lives of several hours in air. The mechanism of this photoinduced electron transfer in the solid state and the origin of the long-lived charge-separated...

Modulation of Bambusuril Anion Affinity in Water

Vaclav Havel, Michal Babiak & Vladimir Sindelar
Abstract Neutral and negatively charged anion receptors functioning in pure water are rare in supramolecular chemistry. Moreover, studies on adjusting the affinity of such receptors toward anions i...
