Multifunctional polymer nanoparticles pass critical in vivo test

In an effort to overcome the drug resistance that often occurs in cancer, a team of investigators has developed a nanoparticle made of a blend of polymers that first releases a powerful anticancer drug and then delivers an agent that tricks a drug-resistant cell into committing suicide. Now, tests in mice with human breast cancer have shown that these blended nanoparticles are effective in maintaining high levels of both drugs in the vicinity of tumors.

Nanobubbles deliver targeted cancer drugs using ultrasound

Using a combination of polymers that respond to temperature, a research team at the University of Utah has developed a multifunctional nanoparticle that can image tumors using ultrasound and simultaneously deliver cell-damaging energy and anticancer drugs to those tumors. In addition, these nanoparticles appear to act specifically on tumors and not on healthy tissue.

New pig model of cystic fibrosis provides better understanding of human disease

For the first time, researchers have developed a genetically altered animal model for cystic fibrosis (CF) that closely matches the characteristics of the disease in humans. By studying the complex and multi-organ disease process in the pig model, researchers can now better understand how the complications of CF develop, an advancement that may lead to new avenues for research in prevention and treatment.

Researchers investigate impact of stress on police officers' physical and mental health

Policing is dangerous work, and the danger lurks not on the streets alone. The pressures of law enforcement put officers at risk for high blood pressure, insomnia, increased levels of destructive stress hormones, heart problems, post-traumatic stress disorder (PTSD) and suicide, University at Buffalo researchers have found through a decade of studies of police officers.

Oversize waistlines are a potent risk factor for heart disease in women

A heart expert at Johns Hopkins is calling for all women with a waistline measuring more than 35 inches to get an annual check-up and detailed risk assessment for heart problems because excess abdominal fat, even in the mildly obese and overweight, leads more than a third of women to underestimate their lifetime risk of having a heart attack, stroke or chest pain (angina).
