Control by light and oxygen of the formation of B875 and 13850 pigment-protein complexes in ~hodopse~domon~s sphueroides was evaluated by use of Hill plots. Kinetics of oxygen-de~ndent control exhibited Hill coefficients of n = 1.06 and n = 0.65 for B875 and 8850 complexes, respectively. Halfmaximum inhibition of B875 complexes was at 20.4% air saturation of the medium and of B850 complexes at 0.9%. Light controlled both complexes with an identical sigmoidal kinetics of n = 2.1.

Bei intensiv vorbehandelten und nicht transplantablen Patienten mit diffus großzelligem B-Zell-Lymphom (DLBCL) ist der therapeutische Bedarf ungebrochen hoch. Doch wurden mittlerweile neue Targets identifiziert, die sich therapeutisch nutzen lassen, berichtete Dr. Mar Maerevoet, Brüssel, Belgien, auf der EHA-Jahrestagung 2017.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
