Introduction And Objective: This study aims to assess the effectiveness of the use of intraoperative fluorescence with 5-ALA on the scope on the resection and the results of the treatment of patients. Despite the continuous development of new oncological treatments, surgical resection remains the basis for treating high-grade gliomas. For this reason, methods are introduced to facilitate the removal of the tumour in a maximally complete and safe manner for the patient.

Article Synopsis
  • Gastric cancer (GC) is a major health issue, ranked as the fifth most common cancer and cause of cancer death globally, with early-onset gastric cancer (EOGC) affecting individuals up to 45 years old making up about 10% of cases.
  • * EOGC tends to be more aggressive and is often diagnosed at a later stage, leading to a poor median survival rate of less than 12 months for advanced GC.
  • * The causes of EOGC are not well understood, but genetic factors may play a significant role, and proper diet and lifestyle choices can help in prevention, despite traditional risk factors being less applicable.

Background: Cannabis, more commonly known as marijuana or hemp, has been used for centuries to treat various conditions. Cannabis contains two main components cannabidiol (CBD) and tetrahydrocannabinol (THC). CBD, unlike THC, is devoid of psychoactive effects and is well tolerated by the human body but has no direct effect on the receptors of the endocannabid system, despite the lack of action on the receptors of the endocannabid system.

Monocytes constitute a heterogenous group of antigen-presenting cells that can be subdivided based on CD14, CD16 and SLAN expression. This division reflects the functional diversity of cells that may play different roles in a variety of pathologies including gliomas. In the current study, the three monocyte subpopulations: classical (CD14 CD16 SLAN), intermediate (CD14 CD16 SLAN) and non-classical (CD14 CD16 SLAN) in glioma patients' peripheral blood were analysed with flow cytometry.
