Peptide receptor radiolabeled therapy shows promise against neuroendocrine tumors

According to new Dutch research featured in the September issue of The Journal of Nuclear Medicine, a peptide receptor radiolabeled therapy (PRRT), [177Lu-DOTA0,Tyr3]Octreotate (177Lu-octreotate), is effective not only in decreasing tumor size but also in reducing the severity of side effects that often accompany a cancer diagnosis.

Study: K-complexes control effects of noise on sleep

During sleep, our perception of the environment decreases. However the extent to which the human brain responds to surrounding noises during sleep remains unclear. In a study published this week in Proceedings of the National Academy of Sciences (PNAS), researchers from University of Liège used brain imaging to study responses to sounds during sleep.

Princeton researchers match images of brain activity with complex thought

In an effort to understand what happens in the brain when a person reads or considers such abstract ideas as love or justice, Princeton researchers have for the first time matched images of brain activity with categories of words related to the concepts a person is thinking about. The results could lead to a better understanding of how people consider meaning and context when reading or thinking.
