UC Davis researchers move biotechnology closer to replacing electronic pacemakers

UC Davis researchers have successfully used a custom designed protein and gene delivery system to restore normal heart rhythms in pigs with electronic pacemakers, reducing their dependence on implanted devices. This work suggests that scientists are one step closer to making bioengineering a reality in treating the more than 2.2 million Americans affected by irregular heartbeats. . The UC Davis...

UC Davis study finds HIV hiding from drugs in gut, preventing immune recovery

UC Davis researchers have discovered that the human immunodeficiency virus, the virus that causes AIDS, is able to survive efforts to destroy it by hiding out in the mucosal tissues of the intestine. They also found that HIV continues to replicate in the gut mucosa, suppressing immune function in patients being treated with antiretroviral therapy--even when blood samples from the same individuals...

UC Davis researchers reveal apples' protective ways

Doctors have long been encouraging Americans to add more fruits and vegetables to their daily diets. Now, UC Davis researchers have discovered one way in which flavonoid-rich apples inhibit the kinds of cellular activity that leads to the development of chronic diseases, including heart disease and age-related cancers. . "We've known for a long time that it's the flavonoids in fruits that are pro...

British cattle give TB to badgers, finds UC Davis expert

The controversial practice of killing wild badgers to prevent tuberculosis in cattle is unlikely to succeed, according to a newstudy led by Rosie Woodroffe, an ecologist at the University ofCalifornia, Davis, and a member of Britain's Independent Scientific Group on Cattle TB. . In Britain, farming interests and badger protectionists have battled for 30 years over the merits of culling badgers to...

UC Davis researchers use heated nanoprobes to destroy breast cancer cells in mice

In experiments with laboratory mice that bear aggressive human breast cancers, UC Davis researchers have used hot nanoprobes to slow the growth of tumors -- without damage to surrounding healthy tissue. The researchers describe their work in the March issue of the Journal of Nuclear Medicine. . .. Many researchers have studied heat as a potential treatm...
