Cavitation dose painting technique: A new method for precise drug delivery

If traditional drug delivery were a type of painting, it might be akin to paintball. With good aim, a majority of the paint ends on the bullseye, but it also drips and splashes, carrying streams of paint across the target.

Advanced scan shows brain inflammation related to post-treatment Lyme disease syndrome

More than 1 in 10 people successfully treated with antibiotics for Lyme disease go on to develop chronic, sometimes debilitating, and poorly understood symptoms of fatigue and brain fog that may last for years after their initial infection has cleared up.

Women's brains age slower than men's

A new study has revealed that women have a more youthful brain compared to similar aged male counterparts when it comes to metabolism. The researchers found that with age the rates of metabolism of nutrients slow down in both men and women.

Researchers get close to developing elusive blood test for Alzheimer's disease

People with symptoms of Alzheimer's disease, such as cognitive difficulties, behavior changes and mood swings, may wait months or even years to get a definitive diagnosis. That's because doctors lack a simple, accurate and inexpensive test for it.

Study suggests dopamine release in the brain occurs twice per meal

We know a good meal can stimulate the release of the feel-good hormone dopamine, and now a study in humans from the Max Planck Institute for Metabolism Research in Germany suggests that dopamine release in the brain occurs at two different times: at the time the food is first ingested and another once the food reaches the stomach.

Traditional and new imaging methods used for prostate cancer diagnosis

Prostate cancer is the second prevent type of cancer that exists. Prostate cancer is usually a slowly progressing disease but it can sometimes manifest as an aggressive cancer. Prostate imaging is the primary way to diagnose the disease and this necessity drives its demand in the clinic.

Statins reduce the formation of brown adipose tissue

A certain proportion of the adult population has not only white adipose (or fatty) tissue, but also the brown kind. This brown adipose tissue helps to convert sugar and fat into heat. People with brown adipose tissue are better at regulating their body temperature in the winter, and are less likely to suffer from excess weight or diabetes.
