Amid concerns that the torrent of research papers on COVID-19 could be leading to an excess of sloppy work, a computer scientist who develops automated programs to spot duplicate images in research papers is running his software across the world’s coronavirus preprints. So far, his efforts have yielded mixed success and some controversy.
Researchers report that a feedback inhibition of p53 by nerve growth factor receptor played an essential role in maintaining the sphere formation and proliferation of melanoma-initiating cells (MICs), and in promoting MIC-derived melanoma growth in vivo.

Scientists demonstrated a novel and highly accurate approach for the rapid identification of ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp.) directly from infected wounds in 3D in vitro skin models.
IDEAYA Biosciences, Inc. announced that it has met the clinical protocol criteria for cohort expansion in the cutaneous melanoma cohort of its Phase II basket arm evaluating IDE196 monotherapy in solid tumors harboring GNAQ or GNA11 hotspot mutations (GNAQ/11).
This study compared the phenotypes of adipose tissue-derived mesenchymal stem cells harvested from high-fat diet, streptozotocin-induced type 2 diabetes (T2D) and healthy Chow diet-fed C57BL/6 mice in vitro and their therapeutic effects for the treatment of wound healing in a mouse model of T2D.
