Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators and provide constraints on exotic production mechanisms such as annihilation of dark matter particles. We present a high-statistics measurement of the spectrum of CRe candidate events from 0.3 to 40 TeV with the High Energy Stereoscopic System, covering 2 orders of magnitude in energy and reaching a proton rejection power of better than 10^{4}.

Article Synopsis
  • This study assesses the cost-effectiveness of mobile stroke units (MSUs) compared to standard emergency medical services (EMS) for administering thrombolytics in ischemic stroke patients.
  • The analysis used the incremental cost-effectiveness ratio (ICER) method to evaluate healthcare costs and quality-adjusted life years (QALYs), highlighting considerable variations based on patient disability status and treatment costs.
  • Overall, while MSUs show borderline cost-effectiveness for all eligible patients, they are more favorable for patients without pre-existing disabilities, particularly when focusing on lifetime costs and stroke-specific expenses.

Purpose: Preclinical data motivate clinical evaluation of inhibitors of mitogen-activated protein kinase-interacting kinases 1 and 2 (MNK1/2). We conducted a phase 1b clinical trial to study target engagement and safety of tomivosertib, a MNK1/2 inhibitor, alone and in combination with paclitaxel.

Methods: Eligible patients had metastatic breast cancer resistant to standard of care treatments.

Article Synopsis
  • Acute myeloid leukemia (AML) is a serious blood cancer with few treatment options and a high chance of coming back after chemotherapy.
  • Researchers studied N-myristoylation, a protein modification linked to cancer cell survival, and found that the level of N-myristoyltransferase 2 (NMT2) can indicate patient outcomes.
  • They tested a drug called zelenirstat, which inhibits myristoylation, and found it caused cancer cell death and reduced leukemia in models, suggesting it could be an effective new treatment for AML patients with poor prognoses.
