Liquid biopsy for CNS lymphoma: CSF exosomes and CSF exosomal miR-15a, miR-21, miR-155, miR-210, and miR-19b are promising biomarkers for diagnosis.

Background: Central nervous system lymphoma (CNSL) is a devastating disease with a poor prognosis. Early diagnosis, monitoring of the treatment response, and outcome prediction carry the utmost importance in the management of patients with CNSL. Surgical biopsy is the gold standard for tissue diagnosis, however, this procedure has potential complications.

Effect of Radiotherapy on the Adhesive Interface of Caries-affected Dentin and Bioactive Restorations: A Micro-CT Analysis.

Purpose: This study aimed to analyze the presence of defects within the adhesive interface formed with five bioactive dental materials and caries-affected dentin concerning the timing of radiotherapy (before or after the restorative procedures) by micro-CT.

Methods And Materials: A total of 96 carious human molars were randomly allocated into the following groups based on the timing of the radiotherapy sequence: radiotherapy followed by restoration (RT1) or restoration followed by radiotherapy (RT2). Then, six subgroups were established within these groups based on the type of materials used (n=8).

Hypofractionated Radiation Therapy Suppresses Radioresistance in U87 Human Glioma Cells by Inhibiting Yap1 and Hsp90 Proteins.

Background: Radiotherapy plays a vital role in the management of high-grade gliomas. However, the radio resistance of glioma cells limits the effect of radiation and drives recurrence inside the irradiated tumor volume leading to poor outcomes for patients.

Methods: High-grade glioma cell radioresistance significantly contributes to radiotherapy failure, highlighting the importance of identifying predictive biomarkers for radioresistance.

Promising outcome of patients with recurrent glioblastoma after Gamma Knife-based hypofractionated radiotherapy.

Background: The role of Gamma Knife radiosurgery (GKRS) in recurrent glioblastoma remains unclear. The purpose of this study is to evaluate the effects of GKRS in a group of patients with recurrent glioblastoma, focusing on survival and safety.

Methods: Patients undergoing GKRS for recurrent glioblastoma between September 2014 and April 2019 were included in this study.

Gamma Knife Radiosurgery Modulates micro-RNA Levels in Patients with Brain Metastasis.

Background: The relation between micro-RNA (miRNA) modulation and immune cell activity in high-dose radiation settings is not clearly understood.

Objective: To investigate the role of stereotactic radiosurgery (SRS) in (i) the regulation of tumorsuppressor and oncogenic miRNAs as well as (ii) its effect on specific immune cell subsets in patients with metastatic brain tumors (MBT).

Methods: 9 MBT patients who underwent gamma knife-based stereotactic radiosurgery (GKRS) and 8 healthy individuals were included.
