Scorpion venom helps treat brain tumors
A new method of delivering a dose of radioactive iodine by using a manufactured version of scorpion venom as a carrier targets gliomas without affecting neighboring tissue or body organs.
The first trial in human patients showed the approach to be safe. A larger phase II trial is under way to assess the effectiveness of multiple doses. Dr. Adam N. Mamelak, a neurosurgeon at Cedars-Sinai Medical Center in Los Angeles, led the phase I trial and is first author of an article in the August Journal of Clinical Oncology.
The key ingredient is TM-601, a synthetic version of a peptide found in the venom of the giant yellow Israeli scorpion (Leiurus quinquestriatus). TM-601 can break through the blood-brain barrier, binding to glioma cells and impeding their growth. If further studies confirm TM-601's properties, it could be used in tandem with standard treatments and allow for reduced doses, the researchers said.
MRI or Ultrasound for Evaluating Pelvic Endometriosis?: Seven Takeaways from a New Literature Review
September 13th 2024While noting the strength of MRI for complete staging of disease and ultrasound’s ability to provide local disease characterization, the authors of a new literature review suggest the two modalities offer comparable results for diagnosing pelvic endometriosis.
Diffusion-Weighted MRI and Neoadjuvant Chemotherapy for Rectal Cancer: What New Research Reveals
September 3rd 2024In a comparison of imaging assessments to gauge the effectiveness of neoadjuvant chemotherapy for rectal adenocarcinoma, researchers found the combination of diffusion-weighted imaging and MR tumor regression grading had a 90 percent area under the curve (AUC) and a negative predictive value (NPV) of 93 percent.
FDA Expands Clearance of MRI-Guided AI Platform for Deep Brain Stimulation and Lesioning Techniques
September 3rd 2024Utilizing a new machine learning model, the OptimMRI software may improve radiosurgery applications and lesioning techniques such as MRI-guided focused ultrasound through enhanced targeting of the inferolateral part of the ventral intermediate nucleus (VIM).
