"Miracle" Cancer Drug Gleevec Can be Toxic to the Heart
...normal ABL and a Gleevec-resistant mutant. Gleevec inhibited the normal enzyme but not the mutant, and the mutant ABL “rescued” the heart cells from the toxic effects of Gleevec, proving that ABL is the relevant target. As a result, second-generation Gleevec drugs might also have similar toxicities in the hear...Drug-coated heart stents under scrutiny, after study
...s over the stent, whereas in the latter, the drugs inhibited the growth. This is good as well as bad news. With bare stents, there were all chances for a thick growth of cells that could prove harmful. But it is desirable to have a thin lining of tissues, which the improvised stents lined with drugs do not ...Potential Diagnostic Marker Indicates Effectiveness of Anti-Angiogenic Drugs

...rial sponsored by Roche showed that Arimidex alone inhibited the progression by just 2.4 months after which the cancer continued to progress. Hormone sensitive breast cancer is seen in 66% of postmenopausal breast cancer and 25% are HER2 positive. The cancer is therefore a very aggressive form and the chance...Carcinogens found in Grilled chicken

... normal wound healing, and that this was partially inhibited in mice exposed to cigarette smoke. Based on their findings, the authors suggest that this delay is due to a difference in the recruitment of cells to the site of injury. In addition, the study found that mice exposed to smoke had impaired or delay...Fruit Yogurt Could Play An Important Role In Diabetes Management
... There was much more variation in which extracts inhibited -amylase and ACE-I, and it wasn't necessarily correlated with phenol content says Shetty. Soy yogurts had the highest phenol content overall, and were the best at inhibiting ACE-I.

... states that treating sarcoma cells with imantanib inhibited a growth factor called PDGFR-beta. This had the effect of increasing the sensitivity of the cells to a drug called tumour necrosis factor-related apoptosis-inducing ligand (TRAIL).

While all of the oils tested inhibited the growth of E. coli, oregano oil was the most effective, killing over 50 percent of sample bacteria in 3 minutes at concentrations as small as 0.034 percent, says McHugh, who's now working on improving the kill rate. The second most effective oil...The Immune System May Be Altered By Certain Chemicals
