Expression and Characterization of Relaxin Family Peptide Receptor 1 Variants

Frontiers in Pharmacology, 2022
G-protein coupled receptors (GPCR) transduce extracellular stimuli into the cell interior and are thus centrally involved in almost all physiological-neuronal processes.

A convolutional neural network-based screening tool for X-ray serial crystallography

Journal of Synchrotron Radiation, 2018
Deep learning provides one possible avenue to reduce the data stream generated by serial macromolecular X-ray crystallography. Convolutional neural networks can be trained to recognize the presence or absence of Bragg spots, forming a criterion to veto ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Domain Movements upon Activation of Phenylalanine Hydroxylase Characterized by Crystallography and Chromatography-Coupled Small-Angle X-ray Scattering.

Journal of the American Chemical Society, 2016
Mammalian phenylalanine hydroxylase (PheH) is an allosteric enzyme that catalyzes the first step in the catabolism of the amino acid phenylalanine. Following allosteric activation by high phenylalanine levels, the enzyme catalyzes the pterin-dependent ...

Oxygen Evolution Reaction by Ni‐Hexacyanoferrates Nanocubes Integrated with Trigonal Selenium: Effect, Properties and Performances

Advanced Functional Materials, EarlyView.
This work describes a novel approach to obtain composite submicrometric structures of nickel hexacyanoferrate integrating trigonal selenium with the aim of enhancing the catalytic efficiency in oxygen evolution reaction (OER). Interestingly, the nanostructures undergo a cube‐to‐sphere transition that optimizes surface properties, leading to superior ...

Hydrogen atoms can be located accurately and precisely by x-ray crystallography

Science Advances, 2016
Hydrogen atoms cannot hide from x-rays anymore but can instead be detected very reliably in routine measurements. Precise and accurate structural information on hydrogen atoms is crucial to the study of energies of interactions important for crystal ...

Tumor Microenvironment‐responsive Nanocatalyst for Targeted Chemodynamic Cancer Therapy

Advanced Healthcare Materials, EarlyView.
An Tumor microenvironment‐responsive nanocatalyst system composed of PLGA‐encapsulated Ca–Fe peroxide and polyarginine enables sustainable Fenton reaction in tumors. Low levels of H2O2 (50–100 µm) initiate the nanoparticle degradation, while polyarginine‐derived nitric oxide accelerates Fe3+ reduction, leading to self‐amplifying •OH generation for ...
