Luminescent Cerium(III) Complexes with Poly(mercaptoimidazolyl)borate: A New Emitter Based on S-Coordinating Ligands.

Lanthanide ions are hard Lewis acids and usually form weak bonds with soft sulfur donors, which result in the supposed instability of their complexes with S-coordinating ligands. Compared with luminescent lanthanide complexes with hard nitrogen or oxygen donor ligands, the development of luminescent lanthanide complexes based on sulfur-donor ligands currently lags behind. In this work, two types of poly(mercaptoimidazolyl)borate ligands, one is tridentate and the other is tetradentate, were used for the design and synthesis of two series of novel S-coordinating cerium(III) (Ce(III)) complexes, which were found to be not only luminescent but also with moderate to surprisingly good stability in air.

Background: Knee Osteoarthritis (KOA) is a prevalent condition worldwide, significantly diminishing quality of life and productivity. Except for the alignment change, muscle activation patterns (MAP) have garnered increasing attention as another crucial factor contributing to KOA.

Objective: This study explores the factors, characteristics, and effects of MAP changes caused by KOA, providing a neuromuscular-based causal analysis for the rehabilitation treatment of KOA.

Structural relaxation chirality transfer enhanced circularly polarized luminescence in heteronuclear Ce-Mn complexes.

Circularly polarized luminescence (CPL) materials have developed rapidly in recent years due to their wide application prospects in fields like 3D displays and anti-counterfeiting. Utilizing energy transfer processes to transfer chirality has been proven as an efficient way to obtain CPL materials. However, the physics behind energy-transfer induced CPL is still not clear.

Angiographic features of pediatric stage 4 familial exudative vitreoretinopathy with radial retinal folds.

Purpose: To describe vascular anomalies and nonperfusion areas (NPAs) of stage 4 familial exudative vitreoretinopathy (FEVR) with radial retinal folds (RFs) and analyze their potential clinical significance.

Methods: Retinal detachment (RD) could exceed the RFs due to exudative, rhegmatogenous, or tractional factors, which we could call secondary RD. Fluorescein fundus angiography (FFA) and risk factors for progression to secondary RD of pediatric stage 4 FEVR patients with radial RFs were respectively explored.

Aβ25-35-induced autophagy and apoptosis are prevented by the CRMP2-derived peptide ST2-104 (R9-CBD3) via a CaMKKβ/AMPK/mTOR signaling hub.

We previously reported that the peptide ST2-104 (CBD3, for Ca2+ channel-binding domain 3), derived from the collapsin response mediator protein 2 (CRMP2)-a cytosolic phosphoprotein, protects neuroblastoma cells against β-amyloid (Aβ) peptide-mediated toxicity through engagement of a phosphorylated CRMP2/NMDAR pathway. Abnormal aggregation of Aβ peptides (e.g.

ANATOMIC OUTCOMES OF LENS-SPARING VITRECTOMY FOR STAGE 3 OR 4 FAMILIAL EXUDATIVE VITREORETINOPATHY.

Purpose: To report the anatomic outcomes and retinal structure changes from lens-sparing vitrectomy (LSV) for eyes with Stage 3 or 4 familial exudative vitreoretinopathy (FEVR).

Methods: Overall, 133 consecutive eyes of 119 patients with Stage 3 (51 eyes) or 4 (82 eyes) FEVR who underwent LSV between January 2012 and May 2023 were retrospectively reviewed.

Results: One hundred twenty-nine eyes (97.

Vascular development analysis: a study for tertiary anti-vascular endothelial growth factor therapy after second reactivation of retinopathy of prematurity.

Purpose: To observe the vascular development results of tertiary anti-vascular endothelial growth factor (anti-VEGF) therapy following spontaneous second reactivation of retinopathy of prematurity (ROP).

Methods: This retrospective study included 22 infants (42 eyes) with Type 1 or aggressive ROP (A-ROP) who received three anti-VEGF drug treatments for ROP from January 2018 to December 2022. The vascular growth, possible associated risk factors, and the retinal vascularization (DB/DF ratio) were assessed.

Intra-Anterior Chamber Injection of Ranibizumab in Advanced Pediatric Vitreoretinal Diseases.

Importance: Anti-vascular endothelial growth factor (VEGF) treatment through intravitreal or subretinal administrations has been proven effective for VEGF-driven pediatric vitreoretinal diseases but are not feasible for advanced cases, such as shallow traction retinal detachments or peripheral circumferential retinal detachments which adhere to the lens. Intra-anterior chamber injection (IAcI) of anti-VEGF may be a viable alternative in such cases but needs evaluation.

Objective: To investigate the effects and safety of IAcI of anti-VEGF to treat VEGF-driven pediatric vitreoretinal diseases.

Single-cell and spatial transcriptomics reveal POSTN cancer-associated fibroblasts correlated with immune suppression and tumour progression in non-small cell lung cancer.

Background: Cancer-associated fibroblasts (CAFs) are potential targets for cancer therapy. Due to the heterogeneity of CAFs, the influence of CAF subpopulations on the progression of lung cancer is still unclear, which impedes the translational advances in targeting CAFs.

Methods: We performed single-cell RNA sequencing (scRNA-seq) on tumour, paired tumour-adjacent, and normal samples from 16 non-small cell lung cancer (NSCLC) patients.

A hybrid method of frequency-weighted energy operator and power spectrum fusion to detect bearing faults.

The difficulties in early fault diagnosis of bearings mainly include two aspects: first, the initial damage size of the bearing is small, and the abnormal vibration caused by slight damage to the bearing is very weak. Second, vibration signals collected in actual industrial environments always contain strong noise interference. Therefore, traditional diagnostic procedures are not satisfactory.

Mueller matrix imaging of pathological slides with plastic coverslips.

Mueller matrix microscopy is capable of polarization characterization of pathological samples and polarization imaging based digital pathology. In recent years, hospitals are replacing glass coverslips with plastic coverslips for automatic preparations of dry and clean pathological slides with less slide-sticking and air bubbles. However, plastic coverslips are usually birefringent and introduce polarization artifacts in Mueller matrix imaging.

Associations of MTHFR Polymorphisms and Cytosine Modifications with Early-Gestational Diabetes Mellitus in Chinese Pregnant Women.

Early-Gestational Diabetes Mellitus (Early-GDM) is a complex condition that may cause complications in infants of affected mothers. The aim of this case-control study was to analyze the effects of genetic-epigenetic interaction on Early-GDM and fetal development with respect to cytosine modifications (i.e.

T-type cell mediated photoacoustic spectroscopy for simultaneous detection of multi-component gases based on triple resonance modality.

Enhancing multi-gas detectability using photoacoustic spectroscopy capable of simultaneous detection, highly selectivity and less cross-interference is essential for dissolved gas sensing application. A T-type photoacoustic cell was designed and verified to be an appropriate sensor, due to the resonant frequencies of which are determined jointly by absorption and resonant cylinders. The three designated resonance modes were investigated from both simulation and experiments to present the comparable amplitude responses by introducing excitation beam position optimization.

Background: Nonkeratinizing nasopharyngeal carcinoma (NK-NPC) has a strong association with Epstein-Barr virus (EBV) infection. The role of NK cells and the tumor cell evolutionary trajectory in NK-NPC remain unclear. In this study, we aim to investigate the function of NK cell and the evolutionary trajectory of tumor cells in NK-NPC by single-cell transcriptomic analysis, proteomics and immunohistochemistry.

Warm-White-Light Perdeuterated Dy(III) Complex with a Photoluminescence Quantum Yield of up to 72% in Deuterated Chloroform.

Herein, a deuteration strategy is proposed to enhance the photoluminescence quantum yield (PLQY) of a Dy(III) complex. The perdeuterated Dy(III) complex Dy(D-DPPOP) (D-DPPOP = 6-[bis(phenyl-)phosphoryl]picolinate-) exhibits a high PLQY of up to 72% in deuterated chloroform, which is 4.8 times higher than that of the nondeuterated Dy(III) complex Dy(DPPOP).

Delayed Doublet Emission in a Cerium(III) Complex.

Doublet emission from open-shell molecules has demonstrated its research and application value in recent years. However, understandings of the photoluminescence mechanism of open-shell molecules are far less than that of closed-shell molecules, leading to challenges in molecular design of efficient doublet emission systems. Here we report a cerium(III) 4-(9H-carbozol-9-yl)phenyl-tris(pyrazolyl)borate complex Ce(CzPhTp) with a new luminescence mechanism of delayed doublet emission, which also represents the first example with metal-centered delayed photoluminescence.
