AI Article Synopsis

  • Radar-based microwave imaging is suggested as a useful addition for early breast cancer screening.
  • An algorithm is introduced to accurately predict the time-of-arrival (TOA) of tumor signals using data from a limited number of antennas.
  • The algorithm's effectiveness is validated using data from realistic numerical models of the breast.

Article Abstract

Radar-based microwave imaging has been proposed as a complementary modality for early-stage breast cancer screening. This paper presents an algorithm that may be used to accurately predict the time-of-arrival (TOA) of a tumor response contained in sample data acquired from a small number of antennas in a realistic scenario. The TOA information may be used by many of the existing radar-based methods to detect and localize a tumor response. The robustness of the algorithm is demonstrated with data generated from realistic numerical breast models.

The clinical application of tyrosine kinase inhibitors (TKIs) is rapidly growing and has emerged as a cornerstone in the treatment of both solid tumors and hematologic malignancies. However, resistance to TKI targets and disease progression remain inevitable. Nanocarrier-mediated delivery has emerged as a promising strategy to overcome the limitations of the TKI application.

Interferon alpha (IFNa) is approved for the therapy of patients (pts) with polycythemia vera (PV), a subtype of myeloproliferative neoplasms (MPN). Some pts achieve molecular responses (MR), but clonal factors sensitizing for MR remain elusive. We integrated colony formation and differentiation assays with single-cell RNA seq and genotyping in PV-derived cells vs.

Despite significant progress in cancer treatment, traditional therapies still face considerable challenges, including poor targeting, severe toxic side effects, and the development of resistance. Recent advances in biotechnology have revealed the potential of bacteria and their derivatives as drug delivery systems for tumor therapy by leveraging their biological properties. Engineered bacteria, including , , and , along with their derivatives─outer membrane vesicles (OMVs), bacterial ghosts (BGs), and bacterial spores (BSPs)─can be loaded with a variety of antitumor agents, enabling precise targeting and sustained drug release within the tumor microenvironment (TME).

Toll-like receptor (TLRs) activation in multiple myeloma (MM) cells induces heterogeneous functional responses including cell growth and proliferation, survival or apoptosis. These effects have been suggested to be partly due to increase in secretion of cytokines such as IL-6 or IFNα among others from MM cells following TLR activation. However, whether triggering of these receptors also modulates production of immunoglobulin free light chains (FLCs), which largely contribute to MM pathology, has not been investigated in MM cells before.
