  • TONER AND TWO-COMPONENT DEVELOPER
    Publication number: 20240069457
    Abstract: The toner contains binder resin-containing toner particles and silica fine particle S1, wherein the weight-average particle diameter of the toner is 4.0-15.0 ?m, both inclusive, peaks originating with the silica fine particle S1 are observed in 29 Si-NMR measurement of the silica fine particle S1, and, in the spectrum obtained by 29Si CP/MAS NMR or 29Si DD/MAS NMR, the peak area of a peak corresponding to the D1 unit structure in the silica fine particle S1, the peak area of a peak corresponding to the D2 unit structure in the silica fine particle S1, and the peak area of a peak corresponding to the Q unit structure in the silica fine particle S1 satisfy a prescribed relationship.

  • Simukunin
    Patent number: 9365626
    Abstract: The present invention includes a novel protein, also referred to herein as simukunin, that inhibits the function of several physiologically important enzymes. Simukunin is a potent inhibitor of the blood coagulation cascade, inhibiting Factor Xa and functioning as an efficient anticoagulant. Simukunin also inhibits the serine proteases elastase and cathepsin and demonstrates anti-inflammatory properties. Also included are methods of making and using simukunin.
