New 3D-printed talus replacement surgery to treat avascular necrosis provides life-changing experience

The talus is the part ankle that allows the foot to move in all different directions. High impact injuries like falls, or traffic accidents can cause the talus bone to be fractured, and a high percentage of these injuries result in avascular necrosis (AVN)—the death of the bone. In a first-of-its-kind procedure using 3D printing technology, internationally renowned orthopedic surgeon Dr. Mark Myerson, Director, The Institute for Foot and Ankle Reconstruction at Mercy Medical Center, explains how a talus replacement, tailored to the patient's specific dimensions, can result in a "life-changing experience" for the patient.

New mouse model to aid in development of antiviral compounds, vaccines against Zika virus

Researchers at the University of Wisconsin-Madison School of Veterinary Medicine have developed one of the first mouse models for the study of Zika virus. The model will allow researchers to better understand how the virus causes disease and aid in the development of antiviral compounds and vaccines.

Researchers find mechanism behind pancreatic cancer cells' resistance to certain drugs

Pancreatic cancer is on track to become the second leading cause of cancer-related deaths by 2020. These statistics are due, in part, to pancreatic cancer's resistance to most targeted cancer therapies. Working with pancreatic cancer cells, researchers have now found a mechanism that could be responsible for the cancer's resistance to at least one targeted approach.

Research suggests new pathway for preventing optic nerve damage in KPro recipients

Researchers from Massachusetts Eye and Ear/Harvard Medical School have identified inflammatory factors that cause optic neuropathy in the back of the eye following implantation of a keratoprosthesis (KPro) — similar to what glaucoma patients experience, without the rise of pressure in the eye — and have shown that blocking one of those factors, tumor necrosis factor alpha (TNFa), successfully halts the development of optic nerve damage in a mouse model.

UC San Diego physicians develop potential new therapy for critical limb ischemia

Bioengineers and physicians at the University of California, San Diego have developed a potential new therapy for critical limb ischemia, a condition that causes extremely poor circulation in the limbs and leads to an estimated 230,000 amputations every year in North America and Europe alone to prevent the spread of infection and tissue death.
