MRIs Now Distinguish Between Renal Cancers

A new MRI technique, called “chemical shift,” can help identify the smallest presence of fat. The presence of fat helps differentiate between clear cell renal cell carcinoma and other types of renal cancer. Renal cell carcinoma, or hypernephroma, originates in the proximal convoluted tubule lining. It is the most common kidney cancer (about 80% of cases), and also the most lethal of all genitourinary tumors (genital and urinary-related).

This cancer has the greatest potential to metastasize, which is what makes it so lethal. The five-year survival rate is 60-70% before metastases have spread.

Healthy Ways to Keep Things Interesting

Everyone knows the mundane rules of health: fruits, vegetables, exercise, sleep, and regular doctors visits. We trust that you know your own body well enough to know when to come in for a screening, and when to talk to your doctor.

The First Steps of MRI Mind Reading? Seeing Into Our Dreams.

A study in Japan, with Senior author Yukiyasu Kamitani of Japan’s ATR Computational Laboratories in Kyoto and colleagues from the Nara Institute of Science and Technology and the National Institute of Information and Communications Technology, revealed that fMRI scans can actually portray the imaged that we see in our brains when we are sleeping. The study followed two German scientists from 2011, Martin Dresler and Michael Czisch of the Max Planck Institute of Psychiatry, who used lucid dreamers to help prove that the brain works similarly while asleep and awake. The use of lucid dreamers, or individuals who are aware […]

Not a Runner? Walking is Just as Effective

…For battling heart disease. HealthDay News recently released an article, accompanied by a video, explaining that a brisk walk can help your health just as any run.

They found that it’s distance, not time or speed, which helps your heart. However, running can allow you to cover double the distance in the same amount of time, a daily walk can still be beneficial. Remember though, a brisk walk is not a leisurely stroll; it’s walking for exercise.

So maybe you’ve never been all […]

Your Brain or Your Personality?

What makes you act the way you do? A new study conducted by Colin G. DeYoung and colleagues from the University of Minnesota suggests that certain personality traits are related to certain brain structure sizes.

The study finds that extraverts have an enlarged orbitofrontal cortex, which is the part of the brain that registers rewards. These individuals are cheerful, assertive, and competitive.

However, the study could not find cause-and-effect, meaning scientists are still unsure whether the brain structure causes the personality trait or the trait causes the changes in brain structure, as personalities are (for the most part) constant, but do possess […]

A Healthy Complexion is a Healthy You

As temperatures rise, so does the risk of sunburn. We don’t want you to avoid a central park picnic, but we do want you to be as safe as possible. Zoe Ruderman with Cosmopolitan wrote an article (which can be found here) about the 2011 regulations for practicing safe sun.

The first thing to understand is what you need protection from: sun rays in general. If a sunscreen protects against UVB rays, UVA may still be damaging your skin, especially those with SPF values under 15. The cancerous rays are still a serious hazard.

Next, “waterproof” […]
