Diabetes may weaken teeth and promote tooth decay
RUTGERS UNIVERSITY People with both Type 1 and Type 2 diabetes are prone to tooth decay, and a new study from Rutgers may explain why: reduced strength and durability of enamel and dentin, the hard substance under enamel that gives structure to teeth. Researchers induced Type 1 diabetes in 35 mice and used a Vickers microhardness tester...

Age-related lung changes provide pathway for metastatic growth of dormant melanoma cancer cells
JOHNS HOPKINS MEDICINE FOR IMMEDIATE RELEASE Spreading cancer cells that escape a primary tumor site can seed in tissues distant from the tumor, but may take several years or decades to grow into full metastatic cancers. Understanding of tumor dormancy, the process by which this happens, was incomplete. Now, new laboratory research directed by investigators...
