Adhesive thermosensitive polydopamine hydrogel containing MnO anchored halloysite clay for treatment of ulcerative colitis.

Ulcerative colitis (UC), a common inflammatory bowel disease, causes ulcers of the colon and rectum. One of the important reasons for intestinal lesions caused by UC is that immune cells produce large amounts of reactive oxygen species (ROS). Herein, we developed an adhesive thermosensitive polydopamine hydrogel containing MnO nanozyme anchored halloysite nanotubes (MnO@HNTs@PDA) to remove ROS produced by immune cells and treatment of UC.

Plasma DNA Methylation-Based Biomarkers for MPNST Detection in Patients With Neurofibromatosis Type 1.

Malignant peripheral nerve sheath tumor (MPNST) development is characterized by an altered DNA methylation landscape, which presents a promising area for developing MPNST-specific biomarkers for screening patients with NF1. Genome-wide DNA methylation profiling of a cohort of 13 patients with MPNST (29 samples of tumor and adjacent neurofibroma tissues) and of NF1-MPNST cell lines was performed to identify and validate candidate MPNST-specific CpG sites (CpGs). A logistic regression prediction model was constructed to select MPNST-specific CpGs distinct from adjacent neurofibromas and normal tissues.
