Oxidative stress is a primary contributor to cerebral ischemia/reperfusion (CI/R) injury, and the use of antioxidants represents a crucial therapeutic strategy for managing CI/R injury. This study aims to explore the antioxidant effects of benzyl ferulate on CI/R injury and elucidate its underlying mechanisms. In vivo models of CI/R injury and hypoxia/reoxygenation (H/R) injury in SH-SY5Y cells were established, followed by treatment with benzyl ferulate.

Article Synopsis
  • Tumor Electric Field Therapy (TEFT) shows promise as an effective and safe treatment for glioblastoma but faces challenges in measuring and controlling electric field intensity within tumors.
  • This study utilizes MRI data to create a numerical simulation model that accurately predicts the intracranial electric field generated by TEFT, taking into account the unique electrical properties of different brain tissues.
  • Results indicate that higher load voltage enhances electric field intensity in target areas, while the impact of voltage frequency is minimal, leading to the development of software to optimize TEFT treatment plans.

  • The study aimed to compare the effectiveness and safety of two asparaginase formulations, PEG-ASNase and L-ASNase, in treating adult acute lymphoblastic leukemia (ALL) over a three-year period.
  • Retrospective analysis included 65 adult ALL patients, assessing enzyme activity, asparagine levels, and adverse reactions using various testing methods.
  • Results showed that PEG-ASNase had a longer duration of activity, higher safety profile, and better event-free survival rates compared to L-ASNase, though both had similar remission rates; adverse reactions were generally more common in the L-ASNase group.
