Modeling sRNA-regulated Plasmid Maintenance [PDF]
, 2016 We study a theoretical model for the toxin-antitoxin (hok/sok) mechanism for plasmid maintenance in bacteria. Toxin-antitoxin systems enforce the maintenance of a plasmid through post-segregational killing of cells that have lost the plasmid. Key to their function is the tight regulation of expression of a protein toxin by an sRNA antitoxin.

Toxin-allelopathy among phytoplankton species prevents competitive exclusion [PDF]
Journal of Biological Systems, 2006, 2006 Toxic or allelopathic compounds liberated by toxin-producing phytoplankton (TPP) acts as a strong mediator in plankton dynamics. On an analysis of a set of phytoplankton biomass-data that have been collected by our group in the North-West part of the Bay of Bengal, and by analysis of a three-component mathematical model under a constant as well as a ...

An Overview: Organophosphate Flame Retardants in the Atmosphere
Aerosol and Air Quality Research, 2022 Organophosphate flame retardants (OPFRs) have been adopted as safer alternatives to polybrominated biphenyl ether flame retardants. However, because of their ubiquitous presence in the environment and the growing evidence of health risks, there has been ...
