Immune checkpoint blockade (ICB) is combined with sonodynamic therapy (SDT) to increase response rates and enhance anticancer efficacy. However, the "always on" property of most sonosensitizers in reducing tumor microenvironment (TME) compromises the therapeutic outcome of sonoimmunotherapy and exacerbates adverse side effects. Precisely controllable strategies combining sulfur dioxide (SO) gas therapy with cancer immunotherapy can address these issues but remain lacking.

Background: Sepsis is a life-threatening condition characterized by organ dysfunction due to an impaired immune response to infection. The lungs are highly susceptible to infection, often resulting in acute lung injury (ALI). The immune-related GTPase M (IRGM) and its murine homolog Irgm1 mediate autophagy and are implicated in inflammatory diseases, yet their roles in sepsis-induced ALI remain unclear.

  • A Two-sample Mendelian randomization (MR) analysis was conducted to examine a potential causal link between non-small cell lung cancer (NSCLC) and sepsis, using specific genetic variations (SNPs) as instrumental variables.
  • The research revealed a significant association, indicating that individuals with genetically predicted NSCLC have a higher risk of developing sepsis, especially in those under 75 years old.
  • The findings suggest that NSCLC not only impacts cancer outcomes but can also help in identifying patients at increased risk for sepsis, highlighting the importance of genetic insights in patient care.

  • A 68-year-old woman presented with low back pain for two months, leading to imaging that indicated possible bone metastases due to hyperintense lesions in the lumbar region.
  • Further imaging revealed both osteolytic and mixed osteolytic-osteoblastic lesions with varying degrees of F-FDG uptake, but no primary tumor could be identified.
  • Ultimately, the patient was diagnosed with low-grade myofibroblastic sarcoma after biopsy and surgery, highlighting that this rare condition should be considered when diagnosing multiple bone metastases.

To address the class imbalance issue in network intrusion detection, which degrades performance of intrusion detection models, this paper proposes a novel generative model called VAE-WACGAN to generate minority class samples and balance the dataset. This model extends the Variational Autoencoder Generative Adversarial Network (VAEGAN) by integrating key features from the Auxiliary Classifier Generative Adversarial Network (ACGAN) and the Wasserstein Generative Adversarial Network with Gradient Penalty (WGAN-GP). These enhancements significantly improve both the quality of generated samples and the stability of the training process.

Bcr-Abl is successfully applied to drug discovery as a CML therapeutic target, but point mutation resistance has become a major challenge in the clinical treatment of CML. Our previous studies have shown that the introduction of amino acids as flexible linkers and heterocyclic structures as HBMs can achieve potent inhibition of Bcr-Abl. In continuation of these studies, we further enriched the linker types by developing a library of compounds with -leucine or serine as a linker.
