Substrate recognition principles for the PP2A-B55 protein phosphatase.

The PP2A-B55 phosphatase regulates a plethora of signaling pathways throughout eukaryotes. How PP2A-B55 selects its substrates presents a severe knowledge gap. By integrating AlphaFold modeling with comprehensive high-resolution mutational scanning, we show that α helices in substrates bind B55 through an evolutionary conserved mechanism.

Synthesis and Characterisation of Core-Shell Microparticles Formed by Ni-Mn-Co Oxides.

In this work, core and core-shell microparticles formed by Ni-Mn-Co oxides with controlled composition were fabricated by an oxalate-assisted co-precipitation route, and their properties were analysed by diverse microscopy and spectroscopy techniques. The microparticles exhibit dimensions within the 2-6 μm range and mainly consist of NiO and NiMnO, the latter being promoted as the temperature of the treatment increases, especially in the shell region of the microparticles. Aspects such as the shell dimensions, the vibrational modes of the spinel compounds primarily observed in the shell region, the oxidation states of the cations at the surface of the microparticles, and the achievement of a Ni-rich 811 core and a Mn-rich 631 shell were thoroughly evaluated and discussed in this work.

Renalase inhibition regulates β cell metabolism to defend against acute and chronic stress.

Renalase (Rnls), annotated as an oxidase enzyme, is a GWAS gene associated with Type 1 Diabetes (T1D) risk. We previously discovered that Rnls inhibition delays diabetes onset in mouse models of T1D , and protects pancreatic β cells against autoimmune killing, ER and oxidative stress . The molecular biochemistry and functions of Rnls are entirely uncharted.

Psychopathy measurement practices moderate psychopathy's association with anxiety and depression: A comprehensive meta-analysis.

Theories of psychopathy development traditionally emphasize that individuals high in psychopathy experience diminished internalizing symptoms (e.g., anxiety and depression).

Controllable synthesis and morphology-dependent light emission efficiency of ZnGeO nanophosphors.

ZnGeO is considered a very promising alternative to current luminescent semiconductors. Previous results suggest that its emitted wavelength may depend on different variables, such as particle size and morphology, among others. In this work, we have prepared pure and highly homogeneous ZnGeO nanorods under hydrothermal synthesis conditions with a willemite-like structure.
