Researchers discovered rare molecular interactions between skin molecules and UV-A light that can cause photoaging. The study found that UV-A wavelengths lead to weak molecular transitions, raising oxygen molecule energy levels to a damaging state.
A new study by University of Wisconsin-Madison biochemist Ron Raines found that a ribonuclease A protein in humans has the same cancer-fighting potential as a frog-derived protein. The finding opens a door to creating a new class of natural drugs aimed at fighting cancer without side effects.
Scientists at Duke University Medical Center have created microbubbles that can be used to suspend helium gas, allowing for detailed magnetic resonance images of blood vessels. The technique combines strengths of several imaging technologies and could lead to non-invasive studies on vascular health, perfusion, and anatomy.
Researchers developed mice with human apolipoprotein E4 (apoE4) in the brain, showing learning and memory problems similar to those seen in human Alzheimer's patients. The apoE4 mice performed poorly in tests requiring spatial learning and memory skills.
A new genetic mutation, APC I1307K, is found to modestly increase the risk of hereditary breast cancer in women of Ashkenazi Jewish descent. The mutation's effect is most significant in those who already carry BRCA mutations.
Researchers have discovered a protein in bacteria that protects them from nitric oxide, a toxin produced by the immune system. This mechanism allows bacteria to survive and thrive, with implications for human health and the development of new antibiotics.
A Carnegie Mellon University study found that excessive internet use is associated with decreased social involvement, increased depression, and loneliness. The research, which monitored 169 home computer users over time, suggests that the internet can have negative effects on emotional well-being.
Researchers will evaluate traumatic brain injury treatment at OHSU and Legacy Health System's hospitals, rehabilitation services, and outpatient care. The study aims to better understand long-term outcomes for patients with brain injuries.
