Combining neurologic and blood pressure drugs reduces breast tumor development in mice

Adding a medication used to treat epilepsy, bipolar disorder and migraines to a blood pressure medicine reversed some aspects of breast cancer in the offspring of mice at high risk of the disease because of the high fat diet fed to their mothers during pregnancy. Conversely, this treatment combination increased breast cancer development in the offspring whose mothers had not been fed a high fat diet during pregnancy.

Bone bandage soaks up pro-healing biochemical to accelerate repair

Researchers have engineered a patch or bandage that captures a pro-healing molecule called adenosine that briefly surges at the site of a bone break or fracture to accelerate and improve the natural healing process. In a proof-of-principle study with mice, the bandage helped to accelerate callus formation and vascularization to achieve better bone repair by three weeks.

Breast cancer cells swallow a 'free lunch' of dietary fat particles from the bloodstream

A research team has previously shown that fatty particles from the bloodstream may boost the growth of breast cancer cells. They now show that through an unexpected mechanism not previously described in cancer cells, the fat particles bind to the breast cancer cell surface and are then taken into the cell, providing a large supply of fuel that drives proliferation of the cancer cells.

Long-term study finds faster breast cancer radiation treatment as effective as long course

Approximately half of the patients were randomly assigned whole breast radiation, delivered once per day over 3 to 5 weeks. The other half received external beam APBI which was given twice a day over 5 to 8 days. The study was long-term, with a median followup of 8.6 years.

Being active reduces risk of prostate cancer

Prostate cancer is the most common cancer in men in the UK , yet we still don't know all of its causes. The largest ever study to use genetics as a measurement for physical activity to look at its effect on prostate cancer, reveals that being more active reduces the risk of prostate cancer. Over 140,000 men were included in the study, of which, 80,000 had prostate cancer.

Permanent hair dye and straighteners may increase breast cancer risk

Scientists found that women who use permanent hair dye and chemical hair straighteners have a higher risk of developing breast cancer than women who don't use these products. The study suggests that breast cancer risk increased with more frequent use of these chemical hair products.

Protein defect leaves sperm chasing their tails

Researchers have characterized a protein, called VSP, that keeps sperm swimming in straight lines. Deletion of the protein caused sperm to swim in circles, significantly reducing fertilization rates. VSP also controlled the influx of calcium ions into the flagellum, which is necessary for propulsion of the sperm towards the egg. The researchers hope that their discovery will aid in the development of fertility treatments to enhance sperm motility.
