Here, authors explore the effect of substitution position in platinum(II) dopants with suppressed metal-metal-to-ligand charge transfer features, resulting in prolonged lifetime in the devices.

Gastric cancer is commonly treated by chemotherapy using 5-fluorouracil derivatives and platinum combination, but predictive biomarker remains lacking. Here, the authors develop a 30-gene prediction model to determine the responsiveness to 5-fluorouracil and oxaliplatin-based chemotherapy through the integrative profiling of patient-derived xenografts

A consistency issue with the production of porous polymer-based radiative coatings can be a significant drop in the cooling performance when dried under humid conditions. This issue is efficiently resolved by adding polymer reinforcement.

Label-free trapping of nanoparticles via dielectophoretic forces is traditionally done with electrodes in a horizontal gap layout. Here, the authors present a vertical nanogap architecture, which allows for precise capture and spatiotemporal manipulation of nanoparticles and molecular assemblies.

Even in patients who are initially sensitive, patients treated with platinum-based therapies often go on to relapse and have limited treatment options. Here, the authors report the efficacy and safety of a phase II trial investigating olaparib, pembrolizumab and bevacizumab as maintenance therapy in platinum-sensitive recurrent ovarian cancer.

Tissue resident macrophages are intricately involved in homeostatic processes but also in tissue repair. Here Lee and colleagues show dermis-resident macrophages are a source of thymic stromal lymphopoietin and CCL24, which act on type 2 innate lymphoid cells and eosinophils respectively, to maintain their M2 properties and promote non-healing cutaneous leishmaniasis.

Skin-nerve crosstalk is a major element of skin physiological pathology. Here the authors report a 3D innervated epidermal keratinocyte layer as a sensory neuron-epidermal keratinocyte coculture model on a microfluidic chip using the slope-based air-liquid interfacing culture and spatial compartmentalization.

The application of engineered cardiac tissues is limited due to their immaturity and lack of functionality. Here, the authors develop an integrated culture platform featuring heart extracellular matrix cultured in a microfluidic chip to facilitate cardiac tissue development for versatile biomedical applications.

Kim et al. reveal that TFEB expression is protective in the setting of diet-induced obesity by activating the expression of GDF15 in adipose tissue macrophages in mice and humans.

Thermocapillary effects allow for the selective removal of metallic nanotubes from semiconducting ones, which occurs directly on a wafer substrate.

Aeby et al. report that DCP1A negatively regulates Tsix RNA abundance by suppressing its transcriptional elongation and RNA stability, thus contributing to X-chromosome inactivation.

Neural mechanisms mediating information flow and processing in dendrites are not fully understood. Here the authors developed techniques to map bioelectrical excitations in the dendrites of neurons in acute slices of mouse brain tissue. They developed a holistic picture of the roles of dendritic excitations in spike back-propagation.

In the phase 2 RENOBATE trial, the combination of regorafenib and nivolumab as first-line treatment for unresectable hepatocellular carcinoma exhibited a safe profile and met the primary endpoint with a 31% overall response rate.

Photoelectrocatalytic nitrate reduction offers an opportunity for a lower carbon route to ammonia production but has not been realized due to poor efficiency. Here an efficient modified lead halide perovskite photocathode is coupled to glycerol oxidation anode resulting in a bias-free photocurrent density greater than 20 mA cm⁻².

The classical neuronal-gene corepressor RCOR1/CoREST is paradoxically enriched in transcriptionally active chromatin. Here the authors show RCOR1 is recruited during promoter-proximal pausing and negatively regulates the nascent-transcript synthesis. They also show that an RCOR1-LSD1- HDAC1 complex removes lysine acetylation from RNA polymerase II to repress transcription.

The active-state structure of human DICER bound to pre-miRNA reveals the structural basis for the specificity of DICER in how it selects substrates in a sequence dependent manner, and sheds light on DICER-related diseases.

Microsatellite instability and Epstein–Barr virus positivity represent novel biomarkers of clinical response to PD-1 blockade in patients with metastatic gastric cancer.

The type III secretion system effectors NleB and SseK are glycosyltransferases (GT) that specifically glycosylate arginine residues. Here the authors provide insights into their mechanism by combining X-ray crystallography, NMR, enzyme kinetics measurements, molecular dynamics simulations and in vivo experiments and show that SseK/NleB enzymes are retaining GTs.
