Objective: To establish a model based on intratumoral and peritumoral radiomics for preoperatively differentiating solitary intrahepatic mass-forming cholangiocarcinoma (IMCC) lesions from colorectal cancer liver metastases (CRLM).

Methods: Preoperative MRI scans from IMCC patients were retrospectively obtained from three academic medical centers. Radiomics features were extracted from the intratumoral and multiple peritumoral regions.

Exogenous M2 Macrophage-Loaded Scaffolds Promote Early Periodontal Regeneration by Improving Osteogenic Differentiation, Cell Homing, and Angiogenesis.

Manipulating the immune microenvironment (including the macrophage phenotype) by tissue implants is an important direction in the field of tissue regeneration. This study reports a macrophage-loaded hybrid scaffold construction to improve the response efficiency of implant-macrophage-tissue regeneration axis and precisely polarize macrophages toward the pro-regenerative M2 phenotype in vitro, and constructed an M2 macrophage-loaded hybrid scaffold. The feasibility of using a macrophage-loaded hybrid scaffold for immune-mediated periodontal regeneration is studied in vivo and in vitro.

Integrative analysis of copper dysregulation and cuproptosis in postnatal hematopoiesis.

Copper dysregulation has been linked to human health, disorders, and hematopoiesis. However, the underlying mechanisms remain elusive. Here, we demonstrate the pivotal role of dietary copper via the transporter Slc31a1(Ctr1) in copper homeostasis, but not cuproptosis, during postnatal hematopoiesis.

MRI-based quantification of intratumoral heterogeneity for intrahepatic mass-forming cholangiocarcinoma grading: a multicenter study.

Objective: This study aimed to develop a quantitative approach to measure intratumor heterogeneity (ITH) using MRI scans and predict the pathological grading of intrahepatic mass-forming cholangiocarcinoma (IMCC).

Methods: Preoperative MRI scans from IMCC patients were retrospectively obtained from five academic medical centers, covering the period from March 2018 to April 2024. Radiomic features were extracted from the whole tumor and its subregions, which were segmented using K-means clustering.

Characteristics of phosphorus transformation from vivianite mediated by sulphide.

The release of phosphorus (P) from anaerobic sediments becomes the dominant source of P loading with effective control of external P pollution. As a crucial component responsible for binding P, vivianite (Fe(PO)·8HO) in sediment inevitably impacts the P level and transformation. The release of P from vivianite mediated by sulphide was investigated using simulated overlying water-sediment and chemical reaction systems.

SLC39A10 is a key zinc transporter in T cells and its loss mitigates autoimmune disease.

Zinc homeostasis plays an essential role in maintaining immune function and is tightly regulated by zinc transporters. We previously reported that the zinc transporter SLC39A10, located in the cell membrane, critically regulates the susceptibility of macrophages to inflammatory stimuli; however, the functional role of SLC39A10 in T cells is currently unknown. Here, we identified two SNPs in SLC39A10 that are associated with inflammatory bowel disease (IBD).

The Intestinal Transporter SLC30A1 Plays a Critical Role in Regulating Systemic Zinc Homeostasis.

The essential trace element, zinc, regulates virtually all aspects of cellular physiology, particularly cell proliferation and survival. Diverse families of metal transporters, metallothioneins, and metal-responsive transcriptional regulators are linked to zinc homeostasis. However, the mechanism underlying the regulation of systemic zinc homeostasis remains largely unknown.

Essentiality of SLC7A11-mediated nonessential amino acids in MASLD.

Metabolic dysfunction-associated steatotic liver disease (MASLD) remains a rapidly growing global health burden. Here, we report that the nonessential amino acid (NEAA) transporter SLC7A11 plays a key role in MASLD. In patients with MASLD, we found high expression levels of SLC7A11 that were correlated directly with clinical grade.

Mechanisms of Cinnamomi Cortex against Diabetes Mellitus Explored by Network Pharmacology combined with Molecular Docking and Experimental Validation.

Objective: Cinnamomi cortex (CC), a traditional Chinese herbal medicine, exhibits antidiabetic properties, yet the underlying mechanisms are not fully understood. Our study combined network pharmacology, molecular docking, and experimental validation to elucidate the antidiabetic mechanisms of CC.

Methods: Active components of CC and their potential antidiabetic targets were identified through TCMSP, DisGeNET, and GeneCards.

Associations between cuprotosis-related genes and the spectrum of metabolic dysfunction-associated fatty liver disease: An exploratory study.

Aims: To explore the associations between cuprotosis-related genes (CRGs) across different stages of liver disease in metabolic dysfunction-associated fatty liver disease (MAFLD), including hepatocellular carcinoma (HCC).

Materials And Methods: We analysed several bulk RNA sequencing datasets from patients with MAFLD (n = 331) and MAFLD-related HCC (n = 271) and two MAFLD single-cell RNA sequencing datasets. To investigate the associations between CRGs and MAFLD, we performed differential correlation, logistic regression and functional enrichment analyses.

TDP-43 ameliorates aging-related cartilage degradation through preventing chondrocyte senescence.

Senescent chondrocytes or signaling mechanisms leading to senescence are promising new therapeutic approaches for ameliorating cartilage degradation. Herein, we show that the transactive response DNA/RNA-binding protein (TDP-43) regulates chondrocyte senescence and ameliorates cartilage degradation. First, a significant decrease in TDP-43 was observed in 16-month-old mice compared with younger mice.

Iron silicate perovskite and postperovskite in the deep lower mantle.

Ferromagnesian silicates are the dominant constituents of the Earth's mantle, which comprise more than 80% of our planet by volume. To interpret the low shear-velocity anomalies in the lower mantle, we need to construct a reliable transformation diagram of ferromagnesian silicates over a wide pressure-temperature () range. While MgSiO in the perovskite structure has been extensively studied due to its dominance on Earth, phase transformations of iron silicates under the lower mantle conditions remain unresolved.

Metformin potentiates nephrotoxicity by promoting NETosis in response to renal ferroptosis.

Given the rapidly aging population, aging-related diseases are becoming an excessive burden on the global healthcare system. Metformin has been shown to be beneficial to many age-related disorders, as well as increase lifespan in preclinical animal models. During the aging process, kidney function progressively declines.

Design and application of modified CAD/CAM socket-shield preparation template in immediate implantation in the esthetic area.

Objective: Designed and applicated a modified customized CAD-CAM socket-shield preparation guide template in immediate implant and followed up for 3 years.

Clinical Considerations: Socket-shield technique could improve the esthetic effect of immediate implant restorations by preserving the labial fascicular bone-periodontal complex at the implant site. While the socket-shield technique is highly technique-sensitive.

An Accurate and Individualized Preoperative Estimation Method for the Linear Insertion Depth of Cochlear Implant Electrode Arrays Based on Computed Tomography.

Objectives: Cochlear implantation or auditory brainstem implantation is currently the only accepted method for improving severe or profound sensorineural hearing loss. The length of the electrodes implanted during cochlear implantation is closely related to the degree of hearing improvement of hearing after the surgery. We aimed to explore new methods to accurately estimate the electrode array (EA) linear insertion depth based on computed tomography (CT) images prior surgery, which could help surgeons select the appropriate EA length for each patient.

Causal Effects of Circulating Lipid Traits on Epithelial Ovarian Cancer: A Two-Sample Mendelian Randomization Study.

Ovarian cancer (OC), and particularly epithelial OC (EOC), is an increasing challenge for women. Circulating lipids play different roles in the occurrence and development of OC, but no causal relationship has been confirmed. We used two-sample Mendelian randomization (MR) to evaluate the genetic effects of circulating Apolipoprotein A1 (APOA1), Apolipoprotein B (APOB), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyc-erides (TG) on EOC risks based on summary data obtained from the UK Biobank and the Ovarian Cancer Association Consortium.

A population-based study of precision health assessments using multi-omics network-derived biological functional modules.

Recent technological advances in multi-omics and bioinformatics provide an opportunity to develop precision health assessments, which require big data and relevant bioinformatic methods. Here we collect multi-omics data from 4,277 individuals. We calculate the correlations between pairwise features from cross-sectional data and then generate 11 biological functional modules (BFMs) in males and 12 BFMs in females using a community detection algorithm.
