A biomimetic nanosystem can deliver therapeutic proteins to selectively target cancerous tumors, according to a team of Penn State researchers. Using a protein toxin called gelonin from a plant found in the Himalayan mountains, the researchers caged the proteins in self-assembled metal-organic framework (MOF) nanoparticles to protect them from the body's immune system.
How can minimally invasive heart surgery be performed more effectively and more gently with the help of modern data and image processing algorithms? The Fraunhofer Institute for Medical Image Computing MEVIS in Bremen is working on this question - and has already achieved decisive success.
People with severe mental illness are more than twice as likely to have Type 2 diabetes, with even higher risks among patients who are African American or Hispanic, according to a new study led by UCSF.
Researchers have developed an artificial tissue in which human blood stem cells remain functional for a prolonged period of time. Scientists from the University of Basel, University Hospital Basel, and ETH Zurich have reported their findings in the scientific journal PNAS.
Around two to six per cent of all people with obesity develop obesity already in early childhood; it's in their genetic cards. Obesity-causal mutations in one of their "appetite genes" gives them a strong genetic predisposition for developing obesity, also called monogenic obesity. Their experience of hunger is overruling and their feeling of satiety limited.
The study found poor sleep quality was associated with nighttime snacking and a high likelihood of craving junk food. The study also found that junk food cravings were associated with increased risk of obesity, diabetes and other health problems.
If immunoglobulin E (IgE) antibodies are directed against harmless antigens such as pollen, the result can be an allergic reaction. However the original purpose of these IgE antibodies is to repel harmful exogenous substances rather than to trigger allergies.
