Resentment of his wife and her involvement with the mystical Rasputin was also widespread and helped contribute to the collapse of the monarchy. Also the state of the country during World War One l...

Comment: There was angiocentric involvement, with atypical cells that were positive for the B cell marker CD20, with more benign appearing CD3 positive T cells also present. Reticulin stain showed reticulin proliferation about involved vessels. In situ hybridization of lesions showed strong positivity for EBV. Some members of the audience noted the presence of intranuclear inclusions in the les...

Spencer-Attix Cavity Theory

2 Spencer Bloch And

Let X be a smooth, projective algebraic variety over an algebraically closed field k, and let H(X) denote a Weil cohomology theory. The existence of algebraic cycles on X×X inducing as correspondences the various Künneth projectors π : H(X) → H (X) is one of the standard conjectures of Grothendieck, [8], [9]. It is known in general only for the cases i = 0, 1, 2d − 1, 2d where d = dimX. The pur...

S - Adenosylmethionine decarboxylase Anthony

S-Adenosylmethionine decarboxylase is a key enzyme for the synthesis of polyamines in mammals, plants and many other species that use aminopropyltransferases for this pathway. It catalyses the formation of S-adenosyl-1(methyl th io)-3-propylamine (decarboxyla ted S-adenosylmethionine), which is used as the aminopropyl donor. This is the sole function of decarboxylated S-adenosylmethionine. Its ...
