BACKGROUNDConsidering that trophoblast cell-surface antigen 2 (Trop2) is overexpressed in a wide range of human epithelial cancers, it presents an attractive target for diagnosis and treatment of multiple types of cancer. Herein, we have developed a Trop2-specific radiotracer, 68Ga-MY6349, and present a prospective, investigator-initiated trial to explore the clinical value of 68Ga-MY6349 PET/CT.METHODSIn this translational study, 90 patients with 15 types of cancer who underwent 68Ga-MY6349 PET/CT were enrolled prospectively.

  • The karyotype of most birds is stable over 100 million years, but parrots show significant chromosomal rearrangements that are not well understood.
  • Researchers analyzed four parrot genomes and found frequent chromosome fusions and fissions, primarily occurring independently across different parrot lineages.
  • These rearrangements are linked to the loss of two genes that aid in genome stability, and specific changes have led to the formation of neo-sex chromosomes in parrots.

T cell-engaging therapies involving bispecific T cell engager (BiTE) and chimeric antigen receptor T (CAR-T) cells have achieved great success in the treatment of hematological tumors. However, the paucity of ideal cell surface molecules that can be targeted on glioblastoma (GBM) partially reduces the immunotherapeutic efficacy. Recently, high expression of Fn14 has been reported in several solid tumors, so the strategy of exploiting this specific antigen for GBM immunotherapy is worth studying.

Piezoelectric transducers are convenient enablers for generating and receiving Lamb waves for damage detection. Fatigue cracks are one of the most common causes for the failure of metallic structures. Increasing emphasis on the integrity of critical structures creates an urgent need to monitor structures and to detect cracks at an early stage to prevent catastrophic failures.
