The front cover picture shows triplet-oxygen sensing and singlet-oxygen generation using lanthanide complexes. lanthanides consist of elements the f-block in period six periodic table. Organic ligands play crucial roles complexes as light-harvesting antennas for luminescence generation. More information can be found Review by Y. Kitagawa, Hasegawa, co-workers.

We assessed the generation of reactive oxygen species (ROS: O2-, H2O2, OH . , chemiluminescence) by neutrophils and monocytes from six patients with infectious mononucleosis, ten patients with other viral diseases, and ten normal controls. Neutrophils from infectious mononucleosis patients showed markedly decreased generation of all reactive oxygen species, compared with the two control groups;...

This study focuses on the generation and loss of reactive oxygen species (ROS) in low-temperature atmospheric-pressure rf (13.56MHz) He+O2+H2O plasmas, which are of interest for many biomedical applications. These plasmas create cocktails of ROS containing ozone, singlet oxygen, atomic oxygen, hydroxyl radicals, hydrogen peroxide, and hydroperoxyl radicals, i.e. ROS of great significance as rec...

Structural changes in the tracheal system during development have the potential to allow insects to compensate for varying oxygen availability. Despite possible compensation, oxygen level during development may also affect insect body size. We investigated how atmospheric oxygen level affects the dimensions of the main dorsal tracheae (DT) and masses of larval Drosophila melanogaster (Meigen) r...
