Researchers Use Bubbles in Cancer Treatment and Drug Delivery

...rchers hope to use gas bubbles like corks to block oxygen flow to tumors, or to deliver drugs.// The process of blocking blood flow to a tumor is called embolization, and using gas bubbles is a new technique in embolotherapy. What makes it so promising is that the technique allows doctors to control exact...

Aggresive Therapy Needed for Cervical Spinal Cord Injuries

...ure to fall, organs to get insufficient blood and oxygen and can progress to heart stoppage, says Dr. Vincent J.B. Robinson, nuclear cardiologist and study co-author. “It’s the balance between sympathetic and parasympathetic nervous systems that keeps your heart rate in the normal range,” says Dr. Ruiz-A...

Genes Identified To Protect Heart Muscles

... after exposure to high concentrations of reactive oxygen species (ROS). ROS are a natural by-product of the body's metabolism of oxygen and are known by scientists for their signaling role in cellular activity. The findings revealed t...

Antioxidants Preserve Cone Cells In the Eye

...e photoreceptors die. After rods die, the level of oxygen in the retina goes up, and this work shows that it is the high oxygen that gradually kills the cones. Oxygen damage is also called ‘oxidative damage’ and can be reduced b...

Combination Therapy to the Rescue off Lung Cancer Patients

.... When tumors are targeted with radiation therapy, oxygen is vital to help the radiation damage DNA and kill cancerous cells. While radiation is most effective in destroying cells around the edges of the tumor, it is less effective at targeting the center of the tumor, which tends to be a low-oxygen environ...
