Twig-nesting species of bees in the genus Centris including C. bicornuta, C. analis, C. vittata, and C. nitida, found in the dry forest of Guanacaste Province of Costa Rica, provision their nests with pollen and nectar, rather than pollen and oil as reported for other Centris species. The liquid
It is of great importance to develop selective and stable metal catalysts for the aqueous levulinic acid hydrogenation, yet challenging. Herein, we report a yolk-structured sing atom catalyst (SAC) with amine-modified Ru1/Fe3O4 core and periodic
Fluorescence spectroscopic detection using 5-amino levulinic acid (ALA) may provide an effective, noninvasive approach for early detection of oral cancer. In the present study, the use of ALA-induced fluorescence ratio (red/orange) to differentiate between normal and gingivitis-affected gingiva is
OBJECTIVE
To determine if a novel formulation is effective in killing oral biofilm streptococci in vitro and in vivo.
METHODS
Efficacy of 0.5% levulinic acid and 0.05% sodium dodecyl sulfate (SDS) in killing Streptococcus gordonii CH1, Streptococcus gordonii DL1, Streptococcus mitis NCTC10712,
