Fibroblasts in heterotopic ossification: mechanisms and therapeutic targets.

Heterotopic ossification (HO) refers to the abnormal formation of bone in non-skeletal tissues. Fibroblasts have traditionally been viewed as stationary cells primarily responsible for producing extracellular matrix during tissue repair and fibrosis. However, recent discoveries regarding their plasticity-encompassing roles in inflammation, extracellular matrix remodeling, and osteogenesis-highlight their potential as key contributors to the development of HO.

A Ratiometric Fluorescence Method Based on PCN-224-DABA for the Detection of Se(IV) and Fe(III).

In this study, 3,4-diaminobenzoic acid (DABA) was introduced into the porphyrin metal-organic framework (PCN-224) for the first time to prepare a ratiometric fluorescent probe (PCN-224-DABA) to quantitatively detect ferric iron (Fe(III)) and selenium (IV) (Se(IV)). The fluorescence attributed to the DABA of PCN-224-DABA at 345 nm can be selectively quenched by Fe(III) and Se(IV), but the fluorescence emission peak attributed to tetrakis (4-carboxyphenyl) porphyrin (TCPP) at 475 nm will not be disturbed. Therefore, the ratio of I/I with an excitation wavelength of 270 nm can be designed to determine Fe(III) and Se(IV).

Flexible Fiber Sensors for Real-Time Monitoring of Redox Signaling Molecules in Exercise-Mimicking Engineered Skeletal Muscle.

Real-time monitoring of reactive oxygen and nitrogen species (RONS) in skeletal muscle provides crucial insights into the cause-and-effect relationships between physical activity and health benefits. However, the dynamic production of exercise-induced RONS remains poorly explored, due to the lack of sensing tools that can conform to soft skeletal muscle while monitor RONS release during exercise. Here we introduce dual flexible sensors via twisting carbon nanotubes into helical bundles of fibers and subsequent assembling electrochemical sensing components.

A novel dual-ligand copper-based nanoflower for the colorimetric and fluorescence detection of 2,4-dichlorophenol, epinephrine and hydrogen peroxide.

Background: Nanozymes have the advantages of cost effective, simple synthesis, high durability and stability, and have been widely used in various fields. However, only a few nanomaterials with multiple enzyme-like activity have been reported, and most of the currently developed nanozymes are usually used in colorimetric or fluorescence analysis depending on a single colorimetric or fluorescence signal output. In this study, a copper-based dual-ligand biomimetic nanoflower (Cu-MN) was constructed, which demonstrated potential multiple enzyme-like activity, and was applied to the multi-mode detection of 2,4-dichlorophenol (2,4-DP), epinephrine (EP), and HO.

Construction of pyrimidine derivatives-copper enzyme mimics as colorimetric sensing elements for efficient detection of phenolic compounds and hydrogen peroxide.

As concerns about environmental pollution grow, the rapid identification and quantification of pollutants have become increasingly vital. In this work, a series of pyrimidine derivatives-Cu enzyme mimics (Cytosine-Cu, Cytidine-Cu, and CMP-Cu) with laccase- and peroxidase-like activity were prepared through the coordination of Cu with different pyrimidine derivatives (PDs). The PDs-Cu enzyme mimics contain high levels of Cu and N - Cu coordination structures, which provide sufficient catalytic sites for the substrates.

Dual Metallosalen-Based Covalent Organic Frameworks for Artificial Photosynthetic Diluted CO Reduction.

Directly converting CO in flue gas using artificial photosynthetic technology represents a promising green approach for CO resource utilization. However, it remains a great challenge to achieve efficient reduction of CO from flue gas due to the decreased activity of photocatalysts in diluted CO atmosphere. Herein, we designed and synthesized a series of dual metallosalen-based covalent organic frameworks (MM-Salen-COFs, M: Zn, Ni, Cu) for artificial photosynthetic diluted CO reduction and confirmed their advantage in comparison to that of single metal M-Salen-COFs.

Copper-Catalyzed Enantioselective [4π + 2σ] Cycloaddition of Bicyclobutanes with Nitrones.

The selective construction of bridged bicyclic scaffolds has garnered increasing attention because of their extensive use as saturated bioisosteres of arene in pharmaceutical industry. However, in sharp contrast to their racemic counterparts, assembling chiral bridged bicyclic structures in an enantioselective and regioselective manner remains challenging. Herein, we describe our protocol for constructing chiral 2-oxa-3-azabicyclo[3.

ACE2 alleviates sepsis-induced cardiomyopathy through inhibiting M1 macrophage via NF-κB/STAT1 signals.

Angiotensin-converting enzyme 2 (ACE2), a crucial element of the renin-angiotensin system (RAS), metabolizes angiotensin II into Ang (1-7), which then combines with the Mas receptor (MasR) to fulfill its protective role in various diseases. Nevertheless, the involvement of ACE2 in sepsis-induced cardiomyopathy (SIC) is still unexplored. In this study, our results revealed that CLP surgery dramatically impaired cardiac function accompanied with disruption of the balance between ACE2-Ang (1-7) and ACE-Ang II axis in septic heart tissues.
