Programmed-cell death is an antimicrobial defense mechanism that promotes clearance of intracellular pathogens. Toxoplasma counteracts host immune defenses by secreting effector proteins into host cells; however, how the parasite evades lytic cell death and the effectors involved remain poorly characterized. We identified ROP55, a rhoptry protein that promotes parasite survival by preventing lytic cell death in absence of IFN-γ stimulation.

Enhancing the rate of the oxygen evolution reaction (OER) by doping Ni-based electrocatalysts with guest metals other than Fe (V in this work) and the stability of the metal site should be assessed independent of Fe traces and in relation to the guest metal activity in solution. We examined OER catalysis and its sustainability at vanadium-doped nickel phosphide (NiP-V) independent of the role of Fe traces in alkaline. V was included in NiP by codeposition at cathodic bias (termed V) or postdeposition during the phosphide-to-hydroxide surface transformation at anodic bias in alkaline spiked with VCl (termed V).

Principal Component Analysis (PCA) is a powerful multivariate tool allowing the projection of data in low-dimensional representations. Nevertheless, datapoint distances on these low-dimensional projections are challenging to interpret. Here, we propose a computationally simple heuristic to transform a map based on standard PCA (when the variables are asymptotically Gaussian) into an entropy-based map where distances are based on mutual information (MI).
