Article Synopsis
  • Metastatic brain tumors commonly cause vasogenic edema, which can impact patient prognosis, but there is limited research on its diagnostic significance.
  • This study analyzed MRI data from 60 patients to investigate the correlation between the edema/tumor index (ETI) and tumor histopathology based on the 2021 WHO classification.
  • Results showed that although malignant tumors had larger edema volumes, the ETI didn't significantly correlate with histopathological grades, and ROC analysis indicated ETI wasn't a reliable predictor for malignancy.

  • Heavy eye syndrome (HES) is a unique type of strabismus caused by a significant elongation of the eye's axial length, leading to misalignment and reduced eye movement, often seen in patients with high myopia.
  • Identification of HES relies on multislice computed tomography (MSCT), which reveals a key sign of the condition: the dislocation of the posterior pole from the muscle cone.
  • The preferred surgical option for HES involves techniques that reposition the superior and lateral rectus muscles, as traditional surgeries are less effective and may complicate future treatment.

Background: The new synthesized water-soluble derivatives of C fullerenes are of a great interest to researchers since they can potentially be promising materials for drug delivery, bioimaging, biosonding, and tissue engineering. Surface functionalization of fullerene derivatives changes their chemical and physical characteristics, increasing their solubility and suitability for different biological systems applications, however, any changes in functionalized fullerenes can modulate their cytotoxicity and antioxidant properties. The toxic or protective effect of fullerene derivatives on cells is realized through the activation or inhibition of genes and proteins of key signaling pathways in cells responsible for regulation of cellular reactive oxygen species (ROS) level, proliferation, and apoptosis.
