The size and shape of two brain regions involved in emotion and motivation may differ in young adults who smoke marijuana at least once a week, according to a new study. The findings suggest that recreational marijuana use may lead to previously unidentified brain changes, and highlight the importance of research aimed at understanding the long-term effects of low to moderate marijuana use on the brain.

Researchers using information provided by a magnetic resonance imaging technique have identified regional white matter damage in the brains of people who experience chronic dizziness and other symptoms after concussion. The findings suggest that information provided by MRI can speed the onset of effective treatments for concussion patients.

A new patient-friendly PET/CT scanner does combined exams in just 15 or 20 minutes, and the patient is never completely enclosed. The state-of-the-art system is improving the diagnosis and treatment of cancer, heart disease, epilepsy, Alzheimer's disease and other conditions. "It is the most patient-friendly system of its kind," said a hospital's medical director of Nuclear Medicine.

Green tea is said to have many putative positive effects on health. Now, researchers are reporting first evidence that green tea extract enhances the cognitive functions, in particular the working memory. The findings suggest promising clinical implications for the treatment of cognitive impairments in psychiatric disorders such as dementia.

Each year prostate tissue samples are taken from over a million men around the world -- in most cases using 12 large biopsy needles -- to check whether they have prostate cancer. This medical procedure shows that 70% of the subjects do not have cancer. The examination is unnecessarily painful and involves risk for these patients, and it is also costly to carry out. A patient-friendly examination, which drastically reduces the need for biopsies, and may even eliminate them altogether, has now been developed.

While exploring the promise of magnetic nanoparticle (mNP) hyperthermia in breast cancer treatment, a researcher reviews preclinical studies and discusses plans for early-phase clinical studies in humans. This evolving treatment approach involves the injection of nanoparticles into the tumor, which are then activated with magnetic energy. Once activated the nanoparticles produce heat inside the cancer cell. The heat kills the cancer cell with minimal damage to surrounding tissue.

Men with prostate cancer that is small and confined to the prostate gland but that is at risk of growing and spreading, do better if they are treated with radiotherapy combined with androgen deprivation therapy, which lowers their levels of the male hormone, testosterone, according to new research.

A novel method to 'manipulate the lipid metabolism in the cancer cell to trick them to use more radiolabeled glucose, the basis of PET scanning' is being described by researchers. The current study used the clinically safe drug etomoxir to block prostate cancer cells' ability to oxidize lipids. With the lipid energy source removed, cells switched to glucose metabolism and both cells and mouse models roughly doubled their uptake of radiolabeled glucose.
