Cat and Mouse
The role of cathepsin B, a lysosomal protease implicated in amyloid-beta (Abeta1-42) metabolism, in Alzheimer's disease remains controversial. In this issue of Neuron, Mueller-Steiner et al. manipulate the expression of cathepsin B in aged APP transgenic mice, observing that increased expression degrades preformed oligomeric and fibrillar amyloid, while inactivation accelerates beta-amyloidosis.

متن کاملUndirected Cat-and-Mouse is P-complete
Cat-and-mouse is a two-player game on a finite graph. Chandra and Stockmeyer showed cat-and-mouse is P-complete on directed graphs. We show cat-and-mouse is P-complete on undirected graphs. To our knowledge, no proof of the directed case was ever published. To fill this gap we give a proof for directed graphs and extend it to undirected graphs. The proof is a reduction from a variant of the cir...

متن کاملCat$^1$-polygroups and pullback cat$^1$-polygroups
In this paper, we give the notions of crossed polymodule and cat$^1$-polygroup as a generalization of Loday's definition. Then, we define the pullback cat$^1$-polygroup and we obtain some results in this respect. Specially, we prove that by a pullback cat$^1$-polygroup we can obtain a cat$^1$-group.
