Improved photoprotection in the UVA/visible radiation boundary region is essential to prevent DNA damage, oxidative stress and gene expression changes in human skin

JEADV Clinical Practice, EarlyView.
Abstract Background Studies have demonstrated the potential for damage caused by exposure to radiation at the UVR/visible border region (380–410 nm) and beyond. This includes potentially mutagenic delayed DNA damage, increased gene expression related to photoageing and inflammation, pigmentation and the production of reaction oxygen species ...

Springtime upwelling conditions influence microbial communities and dissolved thiamin compounds in the California Current Ecosystem

Limnology and Oceanography, EarlyView.
Abstract Understanding dissolved concentrations of the essential coenzyme thiamin (vitamin B1) can provide insights into the biological controls on highly productive upwelling systems such as the California Current Ecosystem. To connect thiamin availability with microbial communities in the California Current Ecosystem, we measured concentrations of ...
