BSA-Assisted Synthesis of Au Nanoclusters/MnO Nanosheets for Fluorescence "Switch-On" Detection of Alkaline Phosphatase.

A fluorescence probe for "switch-on" detection of alkaline phosphatase (ALP) was developed based on Au nanoclusters anchored MnO nanosheets (Au NCs-MnO NSs), which were synthesized using bovine serum albumin (BSA) as template through a simple one-pot approach. In the sensing system, MnO NSs function as both energy acceptors and target identifiers, effectively quenches the fluorescence of Au NCs via fluorescence resonance energy transfer (FRET). The presence of ALP catalyzes the hydrolysis of L-ascorbic acid-2-phosphate (AAP) to ascorbic acid (AA), reducing MnO NSs to Mn and facilitate the fluorescence recovery of Au NCs.

Electrochemical Glucose Sensor Based on Dual Redox Mediators.

Electrochemical glucose sensor holds significant promise for the monitoring of blood glucose levels in diabetic patients. In this study, we proposed a novel electrochemical glucose sensor based on 1,10-Phenanthroline-5,6-dione (PD)/Ru(III) as a dual redox mediator. The synergistic effect of PD and Ru(III) was utilized to efficiently facilitate the electron transfer between the enzyme-active center and the electrode.

Heterotopic ossification: Current developments and emerging potential therapies.

This review aimed to provide a comprehensive analysis of the etiology, epidemiology, pathology, and conventional treatment of heterotopic ossification (HO), especially emerging potential therapies. HO is the process of ectopic bone formation at non-skeletal sites. HO can be subdivided into two major forms, acquired and hereditary, with acquired HO predominating.

Dye-sensitized upconversion nanoprobes with ultra-high signal-to-background ratio for visual and sensitive detection of nerve agent mimics.

An exciting upconversion nanoprobe conditioning strategy is proposed to improve the signal-to-background ratio (SBR) through a dye-sensitized strategy, in which the dye functions both as a recognition unit of the detection target and as a sensitizer to amplify the visible luminescence of the lanthanide-doped upconversion nanoparticles (UCNPs), instead of a quencher. The application of this dye-sensitized upconversion nanoprobe to the visual detection of nerve agent mimics diethoxy phosphatidylcholine (DCP) showed excellent detection performance, with up to 110-fold enhancement of the luminescence response of the probe in DCP solution and a detection limit as low as 2 nM. Finally, we performed visual detection of DCP solution and vapor by using test strips containing the probe.

The polycomb protein complex interacts with GATA-6/PPARα to inhibit α-MHC expression.

Transcription factors collaborate with epigenetic regulatory factors to orchestrate cardiac differentiation for heart development, but the underlying mechanism is not fully understood. Here, we report that GATA-6 induces cardiac differentiation but peroxisome proliferator-activated receptor α (PPARα) reverses GATA-6-induced cardiac differentiation, possibly because GATA-6/PPARα recruits the polycomb protein complex containing EZH2/Ring1b/BMI1 to the promoter of the cardiac-specific α-myosin heavy chain (α-MHC) gene and suppresses α-MHC expression, which ultimately inhibits cardiac differentiation. Furthermore, Ring1b ubiquitylates PPARα and GATA-6.

Aromatic-aromatic interactions drive fold switch of GA95 and GB95 with three residue difference.

Proteins typically adopt a single fold to carry out their function, but metamorphic proteins, with multiple folding states, defy this norm. Deciphering the mechanism of conformational interconversion of metamorphic proteins is challenging. Herein, we employed nuclear magnetic resonance (NMR), circular dichroism (CD), and all-atom molecular dynamics (MD) simulations to elucidate the mechanism of fold switching in proteins GA95 and GB95, which share 95% sequence homology.

Immediate weight bearing as tolerated versus delayed weight bearing following intramedullary fixation for geriatric intertrochanteric fractures: a post hoc analysis.

Background: Early weight bearing is crucial for fracture healing after osteosynthesis for intertrochanteric fractures (ITFs). The optimal period to start weight bearing after surgery is still under debate. The aim of this study was to compare immediate weight bearing (IWB) as tolerated with delayed weight bearing (DWB) following intramedullary fixationin elderly ITF patients.

Predicting Rate Constants of Hydrogen Abstraction Reactions between OH/HO and Alkanes by Machine Learning Models.

The hydrogen abstraction reactions by small radicals from fuel molecules play an important role in the oxidation of fuels. However, experimental measurements and/or theoretical calculations of their rate constants under combustion conditions are very challenging due to their high reactivity. Machine learning offers a promising approach to predicting thermal rate constants.

Key Decision-Making in Post-Failed Internal Fixation of Intertrochanteric Fractures Hip Arthroplasty: A Multicenter Retrospective Study on Fracture Healing's Impact on Femoral Component Selection.

Purpose: Following failed internal fixation of intertrochanteric fractures (FIF-ITF), the decision to use a long-stem or standard-stem femoral implant in hip arthroplasty is still debated. This study aimed to explore how the healing status of fractures after FIF-ITF failure affects the choice of femoral stem and clinical outcomes.

Methods: Our retrospective cohort study reviewed 105 cases of patients with FIF-ITF who underwent hip arthroplasty at three tertiary Grade A hospitals between December 2012 and December 2022.

Design of a Dual-Phase TiN-WN electrochemical sensor for HS detection.

Electrode materials are pivotal in fuel cell-based gas sensors, yet conventional Pt-based catalysts often suffer from limitations in electronic structure and stability, restricting the practical application of HS detection. Here, we introduce a Pt catalyst supported by a titanium-tungsten nitride (TiN-WN) composite for an electrochemical HS sensor. Leveraging the multilevel electron transfer of the Pt/TiN-WN composite, this sensor achieves electron accumulation on the Pt surface, yielding enhanced conductivity and abundant active sites for high HS sensitivity.

Background: Hip fracture and multimorbidity represent significant health challenges for older people. Despite evidence that orthogeriatric co-management improves hip fracture management and patients' health outcomes, there is little evidence to understand its effectiveness for patients with multimorbidity. The study aimed to assess the effect of the orthogeriatric co-management care model on older hip fracture patients with multimorbidity.

A novel electrochemiluminescent cytosensor using dual-target magnetic probe recognition and nanozymes-catalyzed cascade signal amplification for precise phenotypic enumeration of CTCs.

The inability of surgical biopsy to monitor the dynamic evolution of cancer cells hampers its capacity to reflect real-time tumor heterogeneity. Circulating tumor cells (CTCs), as a crucial target in liquid biopsy, offer a novel approach for accurate monitoring of tumors. However, the rarity and complex phenotype resulting from epithelial-mesenchymal transition pose challenges for conventional methods such as CellSearch and immunohistochemistry, which have insufficient ability for simultaneous phenotyping and enumeration of CTCs.

The generation of negative air ions (NAI) by furniture contributes to indoor air purification and enhances the living environment. However, commercially available furniture typically relies on surface coatings to release NAI. Over time, the degradation of these coatings leads to a significant decline in NAI release performance, presenting a persistent challenge for sustained effectiveness.
