Aurora Spine Receives IRB Approval: To Commence Registration for Multicenter Study of its SiLO™ Device for SI Joint Pain

“This registry aims to provide interventional pain physicians in the United States with clinical data that supports the safety and effectiveness of the SiLO sacroiliac fixation technique. I am excited to be part of the study and to train others so that we can continue to advance therapies that relieve pain and restore function,” said Jack Diep, M.D., a Pain Medicine Specialist in Lake Havasu City, AZ.

Parkinson’s Disease and latent (hidden viruses) study: The cause of most Parkinson’s disease cases is unknown. However, it is well documented that mitochondrial dysfunction and misfolded α synuclein aggregation are important cellular abnormalities associated with the disease.

In this paper, we use the microcompetition model to show how latent viruses, which infect the central and peripheral nervous systems, can cause the observed mitochondrial dysfunction and excess α synuclein aggregation, and eventually, Parkinson’s disease. View study here published in the Journal of NeuroVirology.

The discovery was made possible by using the microcompetition model.  The model uncovered new relationships between seemingly unrelated observations reported in the scientific literature.  The discovery describes the molecular steps that lead from a latent infection to the clinical symptoms of Parkinson’s disease.  Many common viruses can cause the disease. They include the Epstein-Barr virus (EBV), Cytomegalovirus (CMV), Herpes Simplex Virus 1 (HSV-1), and Varicella Zoster Virus (VZV).

The model shows that an increase in the concentration of these viruses, or copy number, during the latent phase, increases the risk of developing Parkinson’s disease.  What can increase this viral copy number? A damaged immune system.  Events that decrease the efficiency of the immune system include aging, certain medications, surgery, chemotherapy, radiation, stress, and more.

The microcompetition model was used to discover the effects of latent viruses on other diseases too. It was used to show how latent viruses can cause breast cancer (2), and other cancers (3).  The model was created by Hanan Polansky, and was introduced in his book: “Microcompetition with Foreign DNA and the Origin of Chronic Disease.”
