Abstract	Aqueous organic redox-flow batteries (AORFBs) are promising candidates for low-cost grid-level energy storage. However, their wide-scale deployment is limited by crossover of redox-active material through the separator membrane, which causes capacity decay. Traditional membrane permeability measurements do not capture all contributions to crossover in working batteries, including migration and changes in ion size and charge. Here we present a new method for characterizing crossover in operating AORFBs using online

Abstract	Nuclear magnetic resonance (NMR) spectroscopy is a key technique for molecular structure determination in solution. However, due to its low sensitivity, many efforts have been made to improve signal strengths and reduce the required substrate amounts. In this regard, dissolution dynamic nuclear polarization (DDNP) is a versatile approach as signal enhancements of over 10 000-fold are achievable. Samples are signal-enhanced

Abstract	We introduce a method for the detection of weak interactions of small molecules such as metabolites or medicaments that contain deuterated methyl groups with proteins in solution. The technique relies on long-lived imbalances of spin state populations, which are generated by dissolution dynamic nuclear polarization (D-DNP) and feature lifetimes that depend on the frequency of internal rotation of deuterated methyl groups. We demonstrate the technique for interactions between deuterated dimethyl sulfoxide (DMSO- d

Abstract	We report a conformational switch between two distinct intrinsically disordered subensembles within the active site of a transcription factor. This switch highlights an evolutionary benefit conferred by the high plasticity of intrinsically disordered domains, namely, their potential to dynamically sample a heterogeneous conformational space housing multiple states with tailored properties. We focus on proto-oncogenic basic-helix-loop-helix (bHLH)-type transcription factors, as these play key roles in cell regulation and function. Despite intense research efforts, the understanding of structure-function relations of these transcription factors remains incomplete as they feature intrinsically disordered DNA-interaction domains that are difficult to characterize, theoretically as well as experimentally. Here we characterize the structural dynamics of the intrinsically disordered region DNA-binding site of the vital MYC-associated transcription factor X (MAX). Integrating nuclear magnetic resonance (NMR) measurements, molecular dynamics (MD) simulations, and electron paramagnetic resonance (EPR) measurements, we show that, in the absence of DNA, the binding site of the free MAX

Title translation	Applicability of QUIKS in conservatively treated tumor inpatients.
Abstract	Background: Quality improvement in conservative pain management (QUIKS), a module for nonoperative patients in the QUIPS project was tested on a cohort of tumor patients regarding its applicability. Material and methods: Conservatively treated inpatients at the University Hospital of Würzburg (UKW) were prospectively surveyed on the quality of pain management using the QUIKS outcome questionnaire (AZ 129/17, Ethics Committee at UKW). Information on therapy and demographics was taken from the hospital's internal documentation system. Results: During the data collection period 100 conservatively treated inhouse tumor patients from different hospitals were included. Of the patients 74% required assistance in answering the questionnaire. Functional limitations or pain treatment-related side effects were present in 77% of the patients; the average pain level was 6 on the numerical rating scale. The most commonly reported type of pain was back pain and headache. Of the patients 18% received pain therapy with opioids and 26% with nonopioids, adjustment was made in 5% with opioids and in 44% with nonopioids and pain medicine specialists were consulted in 9% of cases. Conclusion: The application of the questionnaire was well accepted by the patients but required a high level of assistance in completing it. A high level of pain was observed during the hospital stay and the adjustment of pain therapy or the involvement of pain medicine specialists was rare. The interpretation of statements regarding the quality of tumor pain may be limited as other (pre-existing) pain entities, such as nontumor-associated pain or chronic tumor pain could not be clearly delineated.

Abstract	We report an experimental approach for high-resolution real-time monitoring of transiently formed species occurring during the onset of precipitation of ionic solids from solution. This is made possible by real-time nuclear magnetic resonance (NMR) monitoring using dissolution dynamic nuclear polarization (D-DNP) to amplify signals of functional intermediates and is supported by turbidimetry, cryogenic electron microscopy, and solid-state NMR measurements. D-DNP can provide drastic signal improvements in NMR signal amplitudes, permitting dramatic reductions in acquisition times and thereby enabling us to probe fast interaction kinetics such as those underlying formation of prenucleation species (PNS) that precede solid-liquid phase separation. This experimental strategy allows for investigation of the formation of calcium phosphate (CaP)-based minerals by

Abstract	Transcription factors are involved in many cellular processes that take place remote from their cognate DNA sequences. The efficiencies of these activities are thus in principle counteracted by high binding affinities of the factors to their cognate DNAs. Models such as facilitated diffusion or dissociation address this apparent contradiction. We show that the MYC associated transcription factor X (MAX) undergoes nanoscale conformational fluctuations in the DNA-bound state, which is consistent with facilitated dissociation from or diffusion along DNA strands by transiently reducing binding energies. An integrative approach involving EPR, NMR, crystallographic and molecular dynamics analyses demonstrates that the N-terminal domain of MAX constantly opens and closes around a bound DNA ligand thereby dynamically tuning the binding epitope and the mode of interaction.

Abstract	Bone trauma interpretation is an important area of forensic anthropology. Notwithstanding the recent realization of the validity of fracture pattern interpretation, knowledge of trauma is largely based on case studies and older experimental work. Gurdjian and coauthors conducted a number of studies on blunt force fracture propagation that are still used today. Fracture propagation was noted to initiate in an area other than the point of impact, then radiate back toward it. Gurdjian's results are often used to suggest that the point of impact is at a location other than the fracture epicenter. This study is an examination and retesting of Gurdjian's theories of fracture propagation using current biomechanics research and technology. Specifically, the relationship of impact site and fracture patterning was tested using cadaver heads. The results demonstrate that fractures radiate from the point of impact, contrary to the theories of Gurdjian.

Abstract	Nanocarriers have tremendous potential for the encapsulation, storage and delivery of active compounds. However, current formulations often employ open structures that achieve efficient loading of active agents, but that suffer undesired leakage and instability of the payloads over time.
