Currently, circularly polarized luminescence (CPL) has drawn wide interest in 3D display, information storage, and optical sensing. However, traditional synthetic paths are often accompanied by low chiral optical intensity and complex processes. Cellulose nanocrystals (CNCs), with the properties of liquid crystals, can spontaneously arrange into the left-handed layered nanofilm, which enables them candidates in the construction of CPL materials.

The construction of tissue engineered blood vessels (TEBVs) with complex structures will be realized using 3D bioprinting technology, which provides a new idea for vascular transplantation. In this paper, the decellularized extracellular matrix (dECM)/nano clay (NC)/sodium alginate (SA) hybrid bioink was prepared to construct tubular scaffolds in vitro by coaxial 3D bioprinting.

Single-cell RNA sequencing (scRNA-seq) was used to identify prognosis-related cell types, and DNA methylation (DNAm)-based models were developed to predict outcomes based on their cellular characteristics.
Methods: We integrated scRNA-seq, bulk data, and clinical information to identify key cell populations associated with prognosis.
Aim: To assess the corneal high-order aberration (HOA) and its correlation with corneal morphological parameters in patients with bilateral keratoconus (KCN) and unilateral Vogt's striae.
Methods: A total of 168 eyes of 84 patients with KCN, whose corneas had definite signs of unilateral Vogt's striae, were enrolled. Corneal HOA and morphological parameters were measured using Pentacam HR.
Objective: To evaluate whether preimplantation genetic testing for aneuploidy (PGT-A) benefits women of advanced reproductive age (≥38 years old) with a diminished ovarian reserve (DOR; not more than three retrieved oocytes).
Design: A retrospective analysis comparing two groups: (a) PGT-A group: women who chose PGT-A and subsequent single re-warmed embryo transfers (ETs) and (b) non-PGT-A group: women who chose not to genetically test their embryos and underwent subsequent fresh or re-warmed ETs of one to two embryos on days 3 or 5.
Subjects: Two hundred and thirty patients underwent PGT-A therapy, with 49 of these individuals undergoing more than one PGT-A cycle.
The development of efficient and durable electrocatalysts for the acidic oxygen evolution reaction (OER) is essential for advancing renewable hydrogen energy technology. However, the slow deprotonation kinetics of oxo-intermediates, involving the four proton-coupled electron steps, hinder the acidic OER progress. Herein, a RuTiO solid solution electrocatalyst is investigated, which features bridged oxygen (O) sites that act as proton acceptors, accelerating the deprotonation of oxo-intermediates.

Introduction: Long-distance robot teleoperation faces high latencies that pose cognitive challenges to human operators. Latency between command, execution, and feedback in teleoperation can impair performance and affect operators' mental state. The neural underpinnings of these effects are not well understood.

The conventional method for the protection and maintenance of the spotted seal population is the captive maintenance of the species in artificially controlled environments. Nevertheless, the efficacy of the captive strategy remains uncertain, with the potential to impact the health of spotted seals through alterations in gut microbiota.

Methods: Patients with primary glenohumeral osteoarthritis who presented to Penn State Bone and Joint Institute's orthopaedic clinic from September 2002 to December 2019 as total shoulder arthroplasty (TSA) candidates were evaluated. MA was determined by the cross-sectional area of each rotator cuff muscle on pre-operative MR and CT scans.

Fuxin is located in the atmospheric channel around Bohai Bay, and its geographical location is very special. Few existing studies have investigated the pollution characteristics and health risk assessment of heavy metals in atmospheric PM during the four seasons in Fuxin, so a total of 180 PM samples were collected from four sampling sites in Fuxin from December 2021 to November 2022. The seasonal distribution characteristics of V, Cr, Mn, Co, Ni, Cu, Zn, Pb, As, Sb, Cd and Ba were analysed via inductively coupled plasma-mass spectrometry (ICP‒MS), and the source of the heavy metals was analysed via the enrichment factor (EF) and principal component analysis (PCA).

Lack of attention to this issue will lead to an underestimation of HHR caused by PTEs. This study establishes a comprehensive regional identification method for health risk assessment (HRA), namely, soil-maize health risk assessment (SMHRA) and applies it to Ziyang, Shaanxi, which is a typical agricultural county.

RVA, digestion experiment and TGA results showed that legume proteins prompted the viscosity peak formation during cooling stage and increased anti-digestion and thermal stability of WS-LA system. FT-IR, Raman, XRD and C NMR results indicated that legume proteins improved the long-range and short-range ordering degree and single-helix structure of WS-LA system.

The controllable crosslinking between the constituting building blocks plays a key role in endowing the hydrogel with injectability through the formation of a uniform 3D interconnected network. Herein, a uniform-unsaturated crosslinking strategy has been devised to quickly construct injectable sodium alginate (SA) hydrogels. Under vigorous stirring, a moderate amount of metal ions can uniformly coordinate with the guluronate moieties of SA molecules, avoiding the locally excessive crosslinking and the loss of injectability caused by traditional dropping and soaking methods.

MBC is characterized by the transformation of tumor epithelium into squamous epithelium and/or mesenchymal components, including differentiation into spindle cells, chondrocytes, and osteocytes. Due to its rarity and invasiveness, there is a paucity of research on MBC prognosis.
