Evaluation of a smartphone-based markerless system to measure lower-limb kinematics in patients with knee osteoarthritis.

OpenCap, a smartphone-based markerless system, offers a cost-effective alternative to traditional marker-based systems for gait analysis. However, its kinematic measurement accuracy must be evaluated before widespread use in clinical practice. This study aimed to evaluate OpenCap for lower-limb joint angle measurements during walking in patients with knee osteoarthritis (OA) and to compare error metrics between patients and healthy controls.

Efficient CH oxidation to C1/C2 oxygenates over cluster-dispersing Rh decorated ZSM-5.

Crafting highly dispersed active metal sites on catalysts is an optimal method for improving the catalytic reactivity and stability, as it would improve atomic utilization efficiency, enhance reactant adsorption and activation ability through unique geometric and electronic properties. In this study, two synthesis methods were employed (ammonia evaporation (AE) and the impregnation method (IM)) to load Rh species onto the ZSM-5 support in order to attain tunable dispersivity, during which a 1.25-fold increase in the total yield of liquid oxygenated products (32 433.

Patients were divided into three groups: venetoclax combined with hypomethylating agents group (targeted therapy group), standard chemotherapy group, and low-dose chemotherapy group.

Deciphering the endogenous SUMO-1 landscape: a novel combinatorial peptide enrichment strategy for global profiling and disease association.

Small ubiquitin-like modifier (SUMO) plays a pivotal role in diverse cellular processes and is implicated in diseases such as cancer and neurodegenerative disorders. However, large-scale identification of endogenous SUMO-1 faces challenges due to limited enrichment methods and its lower abundance compared to SUMO-2/3. Here we propose a novel combinatorial peptide strategy, combined with anti-adhesive polymer development, to enrich endogenous SUMO-1 modified peptides, revealing a comprehensive SUMOylation landscape.

A machine learned potential for investigating single crystal to single crystal transformations in complex organic molecular systems.

The packing of organic molecular crystals is often dominated by weak non-covalent interactions, making their rearrangement under external stimuli challenging to understand. We investigate a pressure-induced single-crystal-to-single-crystal (SCSC) transformation between two polymorphs of 2,4,5-triiodo-1-imidazole using machine learning potentials. This process involves the rearrangement of halogen and hydrogen bonds combined with proton transfer within a complex solid-state system.

Switchable modes of azulene-based single molecule-electrode coupling controlled by interfacial charge distribution.

Molecule-electrode interactions are critical for determining transport mechanisms and device functionalities in both single-molecule electrochemistry and electronics. Crucial factors such as anchoring groups and local fields have been studied, but the role of electrolytes and interfacial charge distribution remains largely underexplored. The present research focuses on how the interfacial charge distribution in the electric double layer (EDL) controls single-molecule junctions anchored by azulene.

Simultaneous Regulating the Surface, Interface, and Bulk via Phosphating Modification for High-Performance Li-Rich Layered Oxides Cathodes.

Li-rich Mn-based layered oxides (LRMOs) are regarded as the leading cathode materials to overcome the bottleneck of higher energy density. Nevertheless, they encounter significant challenges, including voltage decay, poor cycle stability, and inferior rate performance, primarily due to irreversible oxygen release, transition metal dissolution, and sluggish transport kinetics. Moreover, traditionally single modification strategies do not adequately address these issues.

Multi-resonance emitters with room-temperature phosphorescence in amorphous state and excited by visible light.

Unlike boron, nitrogen-containing multi-resonance emitters with thermally activated delayed fluorescence, here we report boron, sulfur (B, S)-based multi-resonance emitters with room-temperature phosphorescence (RTP) by inserting thiophene into a 5,9-dithia-13-boranaphtho[3,2,1-]anthracene skeleton that simultaneously realizes large singlet-triplet energy splitting and strong spin-orbital coupling, leading to efficient room-temperature phosphorescence in an amorphous state. Unlike most RTP emitters with ultraviolet excitation, the multi-resonance RTP emitters exhibit strong phosphorescence under daily-use blue/white LED lamps owing to their intense absorption in the visible-light region (400-486 nm). Meanwhile, such RTP behavior can be tuned by the number and fusing pattern of the thiophene moieties, with the emitters containing thiophene linked to boron atoms α-positions exhibiting bathochromatically shifted emissions and longer phosphorescence lifetimes (47.

FragGen: towards 3D geometry reliable fragment-based molecular generation.

3D structure-based molecular generation is a successful application of generative AI in drug discovery. Most earlier models follow an atom-wise paradigm, generating molecules with good docking scores but poor molecular properties (like synthesizability and drugability). In contrast, fragment-wise generation offers a promising alternative by assembling chemically viable fragments.

Bioinspired and biomimetic nucleobase-containing polymers: the effect of selective multiple hydrogen bonds.

Bioinspired and biomimetic nucleobase-containing polymers are a series of polydisperse nucleic acid analogs, mainly obtaining through highly efficient and scalable step-growth or chain polymerizations. The combination of pendant nucleobase groups and various backbones endows the polymers/materials with selective multiple H-bonds under distinct conditions, demonstrating the broad applicability of this new family of polymeric materials. In this perspective, we critically summarize recent advances of bioinspired and biomimetic nucleobase-containing polymers and materials in both solution and the bulk.

Effect of Intravenous Tirofiban Versus Placebo on First-Pass Successful Reperfusion in Endovascular Stroke Thrombectomy: Insights From the RESCUE BT Randomized Clinical Trial.

Background: First-pass successful reperfusion (FPSR), defined as a successful/complete reperfusion achieved after a single thrombectomy pass, is predictive of favorable outcome in patients with acute ischemic stroke with large-vessel occlusion. It is unknown whether intravenous tirofiban is effective in increasing the rate of FPSR in acute anterior large-vessel occlusion stroke.

Methods And Results: Patients who had acute large-vessel occlusion stroke presenting within 24 hours and underwent endovascular thrombectomy were analyzed from the RESCUE BT (Intravenous Tirofiban for Patients With Large Vessel Occlusion Stroke) clinical trial, of which the main analysis was neutral.

Boosting exciton dissociation in anion and cation co-doped polymeric semiconductor for selective oxidation reaction.

The inherently low dielectric properties and weak shielding effect of polymeric semiconductors cause excitons to dominate their photoexcitation process, which greatly restricts the photocatalytic performances mediated by charge carriers. Here, an anion and cation co-doping strategy was proposed to weaken the binding energy of excitons by forming distinct positive and negative charge regions, where the charge asymmetry produced an external potential to drive exciton dissociation. Using polymeric carbon nitride as a typical model framework, we show that the incorporation of anions (Cl, Br, I) and cations (Na, K) could create a significant spatial separation of electrons and holes, thereby promoting exciton dissociation.
