New technique can track drug and gene delivery to cells

University of Illinois researchers say they now know how to track and map drug and gene delivery vehicles to evaluate which are most effective at infiltrating cells and getting to their targets, insight that could guide development of new pharmaceutical agents. The researchers described their tracking system and their findings on the most effective delivery vehicles in the journal Nature Communications. 

Brazilians with less education more likely to report being in poor health, study finds

Brazilians with less education are more likely to self-report as being in poor health, according to a study using data from nationwide surveys distributed every five years from 1998 to 2013. The study also found that general subjective health did not improve over the study period, even though more people gained education throughout the study, indicating that other factors associated with poor education may need to be addressed to improve self-perceptions of health.

For nurses in Illinois, expectation of violence ‘a fundamental part of the job,’ study says

Workplace violence is an endemic problem for front-line health care workers in Illinois, says new research from U. of I. labor and employment relations professor Emily E. LB. Twarog.

Prosthetic arms can provide controlled sensory feedback, study finds

Losing an arm doesn’t have to mean losing all sense of touch, thanks to prosthetic arms that stimulate nerves with mild electrical feedback. University of Illinois researchers have developed a control algorithm that regulates the current so a prosthetics user feels steady sensation, even when the electrodes begin to peel off or when sweat builds up. 

Study explores carbohydrates’ impact on head, neck cancers

Consuming high amounts of carbohydrates and various forms of sugar during the year prior to treatment for head and neck cancer may increase patients’ risks of cancer recurrence and mortality, a new study reports.

New camera gives surgeons a butterfly’s-eye view of cancer

Cancer lurking in tissue could be more easily found when looking through a butterfly’s eye.

Federal officials urged to increase perinatal depression treatment in minority women

Federal funding is needed to improve diagnosis and treatment of perinatal depression in Latina and black women, according to University of Illinois kinesiology and community health professor Sandraluz Lara-Cinisomo. 

Optimistic Latinos have healthier hearts, study finds

Latinos who are the most optimistic are more likely to have healthy hearts, according to a new study of more than 4,900 Latinos in the U.S. led by University of Illinois social work professor Rosalba Hernandez.

Emotional suppression reduces memory of negative events

By peering at the brains of study subjects prompted to suppress negative emotions, scientists have gained new insights into how emotional regulation influences negative feelings and memories. They hope the findings will lead to new methods to combat depression.

Study yields more than a million new cyclic compounds, some with pharmaceutical potential

Researchers say they can now produce a vast library of unique cyclic compounds, some with the capacity to interrupt specific protein-protein interactions that play a role in disease. The new compounds have cyclic structures that give them stability and enhance their ability to bind to their targets.
