Inflammation and drugs to control this activity studied in a variety of tumors sites

...rst time that anyone has looked at this particular relationship ?the potential effects of antihistamines on the development of brain tumors in adults," said Scheurer. "It's apparent that some type of inflammatory response is playing some role in the development of brain tumors. We don't know exactly what that rol...

Heat-shock protein vaccine reduces alveolar bone loss

...hogenic bacteria. There was a very strong inverse relationship between post-immune anti-P. gingivalis HSP immunoglobulin G levels and the amount of alveolar bone loss induced by either P. gingivalis or multiple bacterial infection (p = 0.007). Analysis of data from polymerase chain-reaction indicated that the v...
