Article Synopsis
  • Adenoid cystic carcinomas (AdCC) of salivary gland origin are primarily defined by the presence of specific gene fusions, notably MYB::NFIB and MYBL1::NFIB, with sinonasal AdCC being particularly aggressive and lacking effective treatments.
  • Researchers conducted an extensive analysis of 88 sinonasal AdCC cases using various techniques like NGS and FISH to identify gene fusions and mutations, finding that the majority harbored canonical fusions while some had noncanonical ones, with a few tumors showing no fusions at all.
  • Mutational analysis revealed that about 68% of AdCCs tested (21 out of 31) had mutations in key oncogenes, highlighting potential areas for targeted

The development of computational models for the prediction of cardiac cellular dynamics remains a challenge due to the lack of first-principled mathematical models. We develop a novel machine-learning approach hybridizing physics simulation and graph networks to deliver robust predictions of cardiomyocyte dynamics. Embedded with inductive physical priors, the proposed constraint-based interaction neural projection (CINP) algorithm can uncover hidden physical constraints from sparse image data on a small set of beating cardiac cells and provide robust predictions for heterogenous large-scale cell sets.

Article Synopsis
  • Lipid-containing vacuoles in microglia have been associated with neurodegenerative disorders for over a century, and recent studies show altered lipid metabolism in these conditions.
  • Research focused on how lipid-enriched nanoparticles affect microglia, revealing that these nanoparticles lead to vacuolization and the formation of Gitterzellen, a distinct microglia phenotype seen in Alzheimer's disease.
  • The study suggests that lipid-nanoparticles trigger this process through specific pathways, providing a valuable in vitro model to investigate the long-term effects of neurodegeneration.

Sclerosing mucoepidermoid carcinoma (SMEC) of the salivary glands is a rare variant of low-grade mucoepidermoid carcinoma with scanty cellular atypia characterized by marked fibrosis/sclerosis and a rich inflammatory infiltrate. Herein, we report 25 unpublished cases of SMEC, two of them with prominent eosinophilia (2/25; 8%) and three with abundant IgG4-positive plasma cells (3/25; 12%). In our series of salivary SMEC, molecular analysis using fluorescence in situ hybridization (FISH) and/or next-generation sequencing (NGS) provided evidence of MAML2 gene rearrangement in 18 cases of the 21 analyzable cases tested (86%), while this gene locus was intact in 3 cases (14%).
