Shape of prostate and compartments in gland differ in men with cancer, research reveals

Preliminary computerized imaging reveals the shape of the prostate and a compartment within the gland--called the transitional zone--consistently differ in men with prostate cancer than those without the disease, according to new research led by Case Western Reserve University.

Brain response patterns to rewards may be influenced by gene variants affecting pain sensitivity

Patterns of brain responses to rewards are a significant predictor of pain symptoms—a link that is already present by adolescence—and may be influenced by gene variants affecting pain sensitivity, reports a study in PAIN, the official publication of the International Association for the Study of Pain. The journal is published by Wolters Kluwer.
