Objective: To assess the feasibility of positron emission tomography/magnetic resonance imaging (PET/MR) with 18F-fluordeoxyglucose (FDG) for initial staging of sarcoma.
Materials And Methods: Twenty-nine patients with sarcoma were included in this study. Weighted kappa (κ) was used to assess the agreement between PET/MR and conventional imaging (CT and MR). The accuracy of PET/MR and conventional imaging for distant metastases was compared using receiver operating characteristic (ROC) analysis.
Results: T and M stage were identical for PET/MR and conventional modalities in all patients (κ=1). N stage was identical for 28/29 patients (κ=0.65).
Conclusions: FDG PET/MR shows excellent agreement with the currently preferred imaging methods (CT and MR) in initial staging of sarcoma.

The skin, as the body's largest organ, plays a crucial role in protecting against mechanical forces and infections, maintaining fluid balance, and regulating body temperature. Therefore, skin wounds can significantly threaten human health and cause a heavy economic burden on society. Recently, bioelectric fields and electrical stimulation (ES) have been recognized as a promising pathway for modulating tissue engineering and regeneration of wounded skin.

Dormancy is an adaptation in which cells reduce their metabolism, transcription, and translation to stay alive under stressful conditions, preserving the capacity to reactivate once the environment reverts to favorable conditions. Dormancy and reactivation of () are closely linked to intracellular residency within macrophages. Our previous work showed that murine macrophages rely on the viable but not cultivable (VBNC-a dormancy phenotype) fungus from active , with striking differences in immunometabolic gene expression.

Hepatocellular carcinoma (HCC) is a widely prevalent type of primary liver cancer. However, strategies for pretumor intervention are still limited. In this study, a liver-specific Zbtb7b knockout mouse model was used to evaluate the role of Zbtb7b in metabolic dysfunction-associated steatotic liver disease (MASLD)-related HCC development.

Obtaining stable hepatic cells in culture poses a significant challenge for liver studies. Bearing this in mind, an optimized method is depicted utilizing human induced pluripotent stem cells (hiPSCs) to generate 3D cultures of human hepatic organoids (HHOs). The utilization of HHOs offers a valuable approach to understanding liver development, unraveling liver diseases, conducting high-throughput studies for drug development, and exploring the potential for liver transplantation.
