Idiopathic inflammatory myopathies (IIMs) are a group of autoimmune disorders characterized by immune cell infiltration of muscle tissue accompanied by inflammation. Treatment of IIMs is challenging, with few effective therapeutic options due to the lack of appropriate models that successfully recapitulate the features of IIMs observed in humans. In the present study, we demonstrate that immunodeficient mice transplanted with human peripheral blood mononuclear cells (hPBMCs) exhibit the key pathologic features of myositis observed in humans and develop graft-versus-host disease.

Background: Current diagnostic imaging modalities have limited ability to differentiate between malignant and benign pancreaticobiliary disease, and lack accuracy in detecting lymph node metastases. F-Prostate-Specific Membrane Antigen (PSMA) PET/CT is an imaging modality used for staging of prostate cancer, but has incidentally also identified PSMA-avid pancreatic lesions, histologically characterized as pancreatic ductal adenocarcinoma (PDAC). This phase I/II study aimed to assess the feasibility of F-PSMA PET/CT to detect PDAC.

Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer with limited treatment options and a poor prognosis. The critical role of epigenetic alterations such as changes in DNA methylation, histones modifications, and chromatin remodeling, in pancreatic tumors progression is becoming increasingly recognized. Moreover, in PDAC these aberrant epigenetic mechanisms can also limit therapy efficacy.

Background: Axial spondyloarthritis (SpA) leads to structural bone lesions in every part of the vertebral column. These lesions are only partially visualized on conventional radiographs, omitting posterior parts of the vertebral column and the thoracic spine, that may nevertheless contribute to impaired spinal mobility and function in patients with axial SpA.
Methods: In this prospective and blinded investigation, we assessed the distribution of structural spinal lesions using magnetic resonance imaging (MRI) of the whole spine in 55 patients with axial SpA classified according to the Assessment in Spondyloarthritis International Society (ASAS) criteria.

Department of Nephrology, Affiliated Hospital of Jiaxing University (The First Hospital of Jiaxing), No.1882, Zhonghuan North Road, Jiaxing, 314000, Zhejiang, China.
Background: Dysfunction in podocyte mitophagy has been identified as a contributing factor to the onset and progression of diabetic nephropathy (DN), and BMAL1 plays an important role in the regulation of mitophagy. Thus, this study intended to examine the impact of BMAL1 on podocyte mitophagy in DN and elucidate its underlying mechanisms.
Materials And Methods: High D-glucose (HG)-treated MPC5 cells was used as a podocyte injury model for investigating the potential roles of BMAL1 in DN.
