Background: Thyroid-associated orbitopathy (TAO) is an autoimmune inflammatory disorder of the orbital adipose tissue, primarily causing oxidative stress injury and tissue remodeling in the orbital connective tissue. Ferroptosis is a form of programmed cell death driven by the accumulation of reactive oxygen species (ROS), iron metabolism disorder, and lipid peroxidation. This study aims to identify and validate the optimal feature genes (OFGs) of ferroptosis with diagnostic and therapeutic potential in TAO orbital adipose tissue through bioinformatics analysis and to assess their correlation with disease-related immune cell infiltration.

Low-intensity laser therapy (LLLT) is recognized for its ability to promote tissue regeneration, reduce inflammation, and alleviate pain. This study aims to explore the specific mechanism of miRNAs-VEGFA pathway regulation in early vascularization after orbital implant placement induced by LLLT.

Amniotic membrane transplantation is commonly employed in ophthalmology to mend corneal epithelial and stromal defects. Its effectiveness in restoring the ocular surface has been widely acknowledged in clinical practice. Nevertheless, there is ongoing debate regarding the comparative effectiveness of using fresh amniotic membranes versus preserved ones.

Methods: C918 cells were cultured in ultra-low adsorption 96-well plates, and morphological changes in C918 three-dimensional cell spheroids were observed over varying time intervals. Histological features of C918 multicellular spheroids cultured in ultra-low adsorption 6-well plates were examined using both HE staining and immunohistochemical staining.
Thirty-two diterpenoids including 18 ent-kauranes (1-6, and 12-23), nine 8,9-seco-ent-kauranes (7-8, and 24-30), four ent-abietanes (9-10, and 31-32), and one crotofolane (11) were isolated from the twigs and leaves of Croton kongensis. The structures of previously unreported crokokaugenoids A-H (1-8), crokoabiegenoids A-B (9-10), and crokocrotogenoid A (11) were determined by spectroscopic data analyses, TDDFT-ECD and GIAO NMR calculations, and X-ray crystallographic studies. All compounds were evaluated for their cytotoxic activity against five human tumor cell lines, and the structure-activity relationships were discussed.

Aims: To find a reliable alternative to hormone pulse therapy for thyroid associated ophthalmopathy by comparing the efficacy with first-line treatment regimens.
Methods: Search PubMed, Ovid, Web of science, Cochrane library, and Clinical Trials.

Methods: The three-dimensional (3D) model of orbital blowout fractures was reconstructed using Mimics21.0 software.
Intestinal organoids are a three-dimensional cell culture model derived from colon or pluripotent stem cells. Intestinal organoids constructed strongly mimic the colon epithelium in cell composition, tissue architecture, and specific functions, replicating the colon epithelium in an culture environment. As an emerging biomedical technology, organoid technology has unique advantages over traditional two-dimensional culture in preserving parental gene expression and mutation, cell function, and biological characteristics.

Tumor loss-of-function mutations in , a regulator of the energy sensor AMP-activated protein kinase, induce cancer cachexia (CC) in preclinical models and are associated with cancer-related weight loss in NSCLC patients. Here we characterized the relevance of the NSCLC-associated cachexia factor growth differentiation factor 15 (GDF15) in several patient-derived and genetically engineered -mutant NSCLC cachexia lines.

However, the repertoire of naturally occurring enzymes repurposed by direct light excitation to catalyze new-to-nature photobiotransformations is currently limited to flavoproteins and keto-reductases. Herein, we shed light on imine reductases (IREDs) that catalyze the remote C(sp)-C(sp) bond formation, providing a previously elusive radical hydroalkylation of enamides for accessing chiral amines (45 examples with up to 99% enantiomeric excess).

Methods: We conducted a retrospective case series analysis, retrospectively collecting and analyzing clinical data of patients with orbital fractures who received surgical treatment at the Affiliated Eye Hospital of Nanchang University from May 2012 to May 2022. Descriptive statistics were employed to document common postoperative complications, and we recorded complications persisting after a minimum 6-month follow-up period.
Repurposing enzymes to catalyze non-natural asymmetric transformations that are difficult to achieve using traditional chemical methods is of significant importance. Although radical C-O bond formation has emerged as a powerful approach for constructing oxygen-containing compounds, controlling the stereochemistry poses a great challenge. Here we present the development of a dual bio-/photo-catalytic system comprising an ene-reductase and an organic dye for achieving stereoselective lactonizations.

We investigated the atomic interface arrangement of Li-montmorillonite (Li-Mt) during low-temperature water-rock reactions and Li migration. The results show that, in Cl-rich systems, deprotonation and exposure of Na adsorption sites cause Li enrichment and O pairing, which lead to the weakening of the shielding effect of Mt on anions and the formation of a Mt-Li-Cl atomically interfacial arrangement.
