Irisin‐Loaded Cerium‐Containing Mesoporous Bioactive Glass for Effective Immunomodulation and Odontogenesis of Dental Pulp Cells

Advanced Science, EarlyView.
The Irisin/Ce‐MBGNs delivery system can slowly release myokine Irisin for vital pulp therapy. Irisin/Ce‐MBGNs can enhance mitochondrial function and promote the differentiation of inflammatory macrophages toward M2‐Mφ, thereby regulating the immune response mechanism of inflamed dental pulp.

Highly Crystalline and Oriented Thin Films of Fully Conjugated 3D‐Covalent Organic Frameworks

Angewandte Chemie, EarlyView.
This work introduces a fully conjugated, 3D covalent organic framework (COF) based on cyclooctatetrathiophene (COTh); the synthesis employs modulated conditions to achieve thin films with high crystallinity. The COTh‐1P COF shows potential for optoelectronic applications, thanks to its π‐conjugated structure, the preferential film orientation, and ...

RSPO2 Coordinates with GDF9:BMP15 Heterodimers to Promote Granulosa Cell and Oocyte Development in Mice

Advanced Science, EarlyView.
RSPO2 and GDF9:BMP15 heterodimers—core components of oocyte‐secreted factors (OSFs)—coordinate to shape the molecular architecture of preantral granulosa cells via gene‐specific synergistic and antagonistic regulation, mediated through CTNNB1–SMAD2 signaling crosstalk.

Biocatalytic Alkylation of Ambident Nucleophiles Enables Selective N‐Functionalization of Heterocycles and Late‐Stage Modifications

Angewandte Chemie, EarlyView.
N‐alkylated heteroarenes are key structural motifs in bioactive compounds, but their regioselective synthesis via coupling of readily available azoles with haloalkanes remains very challenging. Here, we present a mild biocatalytic approach that proceeds on gram‐scale, is highly chemo‐ and regioselective, offering rapid access to valuable N‐alkylated ...

Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

Advanced Science, EarlyView.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

High‐Density Flexible Neural Implants with Submicron Feedline Resolution

Advanced Electronic Materials, EarlyView.
Optimization of microfabrication methods using optical contact lithography (OCL) and electron beam lithography (EBL) enables the fabrication of 64‐channel, high‐density, parylene‐C‐based intracortical implants with submicron feedlines as narrow as 400 and 50 nm, respectively.

Prognostic Impact of Bone Mineral Density Reduction During Neoadjuvant Chemotherapy (NAC) in Patients Undergoing NAC Followed by Esophagectomy for Esophageal Cancer

Annals of Gastroenterological Surgery, EarlyView.
The association between BMD reduction during NAC and the worse prognosis remains unknown, although NAC followed by esophagectomy is a standard treatment for advanced ESCC. This study appeared that BMD massive reduction was an independent prognostic factor on OS (HR, 3.30; 95% confidence interval [CI], 1.69–6.55) and RFS (HR, 2.08; 95% CI, 1.19–3.63 ...
