Osteochondral damage, caused by trauma, tumors, or degenerative diseases, presents a major challenge due to the limited self-repair capacity of the tissue. Traditional treatments often result in significant trauma and unpredictable outcomes. Recent advances in bone/cartilage tissue engineering, particularly in scaffold materials and fabrication technologies, offer promising solutions for osteochondral regeneration.

Magnetic resonance imaging (MRI) is a non-invasive medical imaging technique that is widely used for high-resolution imaging of soft tissues and organs. However, the slow speed of MRI imaging, especially in high-resolution or dynamic scans, makes MRI reconstruction an important research topic. Currently, MRI reconstruction methods based on deep learning (DL) have garnered significant attention, and they improve the reconstruction quality by learning complex image features.

Introduction: Human amniotic membrane (hAM) has a highly biocompatible natural scaffold that is abundant in several extracellular matrix (ECM) components, including but not limited to platelet-derived growth factor (PDGF), transforming growth factor (TGF), and fibroblast growth factor (FGF). In our study, we have focused on a mixture of hAM and demineralized bone matrix (DBM) as an allo-hybrid graft to deliver it into the site of bone defect to decrease bone remodeling time.
Methods: Allo-hybrid grafts were prepared by coating the jelly made of decellularized and lyophilized hAM (AMJ) on the surface of DBM and subsequently underwent in vitro studies, such as alkaline phosphatase activity, MTT assay, and SEM analysis.

Myofibroblastoma is a rare mesenchymal tumour known for its benign nature but complex diagnostic pathway. A woman in her 40s presented with a painless breast mass, initially reported as a fibroadenoma on ultrasound mammography and as a benign to borderline phyllodes tumour on fine needle aspiration cytology. Contrast-enhanced CT was reported as carcinoma of the breast with Breast Imaging and Reporting Data System (BIRADS)-6.

Introduction: Technological advancements in virtual screening (VS) have rapidly accelerated its application in drug discovery, as reflected by the exponential growth in VS-related publications. However, a significant gap remains between the volume of computational predictions and their experimental validation. This discrepancy has led to a rise in the number of unverified 'claimed' hits which impedes the drug discovery efforts.
