High Callous Traits Show Differences In Brain Structure

A study in Biological Psychiatry characterizes the neural profile of callousness in children

Children with elevated levels of callous traits—such as a lack of remorse and disregard for other people's feelings—show widespread differences in brain structure compared with children with lower levels of the traits, according to a new study published in Biological Psychiatry. The differences, which included large- and small-scale structural alterations, support the idea of callous traits as a neurodevelopmental condition.

Understanding The Painful Event Processed In The Brain

Pain is a negative feeling that we want to get rid of as soon as possible. In order to protect our bodies, we react for example by withdrawing the hand. This action is usually understood as a consequence of the perception of pain.

A team from the Technical University of Munich (TUM) has now shown that perception, the impulse to act and provision of energy to take the place in the brain simultaneously and not, as was expected, one after the other.

Early Physical Therapy Reduces Opioid Use

Patients who underwent physical therapy soon after being diagnosed with pain in the shoulder, neck, low back or knee were approximately 7 to 16 percent less likely to use opioids in the subsequent months, according to a new study by researchers at the Stanford University School of Medicine and the Duke University School of Medicine.

'Painless' Adhesive Use in Biomedical Applications

Pulling off a Band-Aid may soon get a lot less painful. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Xi'an Jiaotong University in China have developed a new type of adhesive that can strongly adhere wet materials — such as hydrogel and living tissue — and be easily detached with a specific frequency of light.

Disruption of Circadian Rhythm: A Risk Factor for Diseases

USC scientists report that a novel time-keeping mechanism within liver cells that helps sustain key organ tasks can contribute to diseases when its natural rhythm is disrupted. This dual function of the nuclear receptor protein HNF4A offers a potential explanation for diseases such as diabetes and cancers. It also helps explain why such maladies are more common for people living with disrupted sleep, including night-shift workers, urban dwellers, and international jet-setters.
