Control of Tetrazine Bioorthogonal Reactivity by Rotaxanation. [PDF]

Angew Chem Int Ed Engl
Control of tetrazine‐mediated inverse electron demand Diels–Alder (IEDDA) reaction has been achieved by rotaxanation. Tetrazine rotaxanes were synthesized in high yield and they displayed a much slower kinetics compared to the corresponding thread. Mechanical bond disassembly upon the right stimulus activates reactivity.

Epigenome alterations in food allergy: A systematic review of candidate gene and epigenome‐wide association studies

Clinical &Experimental Allergy, Volume 53, Issue 3, Page 259-275, March 2023., 2023
Data were extracted from seven candidate gene and nine epigenome‐wide association studies on food allergy. Eleven genes with epivariations were common to at least two epigenome‐wide association studies. This review highlights the involvement of epigenomic alterations of loci in Th1/Th2 and regulatory T cell differentiation in both candidate gene ...

Segregational instability of multicopy plasmids: A population genetics approach

Ecology and Evolution, Volume 12, Issue 12, December 2022., 2022
To circumvent the segregational instability resulting from randomly distributing plasmids between daughter cells upon division, nontransmissible plasmids tend to be carried in multiple copies per cell, but carrying multiple copies also results in a high metabolic burden to the bacterial host, therefore reducing the overall fitness of the population ...
