Like cleaning the lenses of a foggy pair of glasses, scientists are now able to use a technique developed by UCLA researchers and their European colleagues to produce three-dimensional images of breast tissue that are two to three times sharper than those made using current CT scanners at hospitals. The technique also uses a lower dose of X-ray radiation than a mammogram.

These higher-quality images could allow breast tumors to be detected earlier and with much greater accuracy. One in eight women in the United States will be diagnosed with breast cancer during her lifetime.

The research is published the week of Oct. 22 in the early edition of the journal Proceedings of the National Academy of Sciences. (more…)

A study by researchers at the UCLA School of Nursing has found that serious male cyclists may experience hormonal imbalances that could affect their reproductive health.

The study, “Reproductive Hormones and Interleukin-6 in Serious Leisure Male Athletes,” was recently published in the European Journal of Applied Physiology.

To date, an extensive amount of research has been done documenting the positive effects of long-term exercise on health. Yet while moderate exercise can lead to enhanced cardiovascular and metabolic function and reduced body fat, studies have shown that ultra-endurance levels of exercise can also adversely affect the neuroendocrine system and reproductive health.
