Reactive Oxygen Species

Salmonella enterica serovar Typhimurium is responsible for a variety of diseases in domestic animals and humans. The infection of mice causes similar disease progression to human typhoid fever, thus representing a model for this systemic disease. The ability of S. Typhimurium to…

In the present study, TiO2 photocatalysis has been investigated for the inactivation of pathogenic bacteria Escherichia coli ATCC 11303, Staphylococcus aureus SH1000 wild type, SH1000 ahpC/katA catalase mutant strains and SH1000 sodA/sodM superoxide dismutase mutant strains. The…

Hematopoietic stem cell (HSC) proliferation and differentiation is tightly regulated to allow blood cell production without exhaustion of the stem cells pool. This is enabled by one of the unique abilities of the hematopoietic stem cell population- their ability to maintain thei…

Reactive Oxygen Species (ROS) are vital to the normal functioning of the immune system in the human body. However, when a foreign material enters the system the highly regulated balance between pro- and anti-oxidants can be disrupted, especially if the material itself can genera…

Reactive oxygen species (ROS) are a series of molecules, ions, and radicals derived from oxygen that possess remarkable reactivity. They act as signaling molecules when their concentration in cells is within a normal range. When the levels of ROS increase, reaching a concentrati…
