Control of nanomotors inside living cells
2/12/2014
For the first time, a team of chemists and engineers at Penn State University have placed tiny synthetic motors inside live human cells, propelled them with ultrasonic waves and steered them magnetically. It's not exactly "Fantastic Voyage," but it's close. The nanomotors, which are rocket-shaped metal particles, move around inside the cells, spinning and battering against the cell membrane.
After percutaneous coronary intervention, surprising trends in cause of long-term death
2/12/2014
More people who have known coronary heart disease die from other causes - such as cancer, and lung and neurological diseases - than heart disease, compared with 20 years ago, according to a Mayo Clinic study published online in Circulation, an American Heart Association journal.
Guideline focused on reducing ipsilateral breast tumor recurrence in stages I and II invasive breast cancer The American Society for Radiation Oncology (ASTRO) and the Society of Surgical Oncology (SSO) are pleased to announce the publication of the consensus guideline on margins for breast-conserving surgery with whole-breast irradiation in stages I and II invasive breast cancer.
'Double mastectomy better' for women with BRCA gene mutation
2/12/2014
Women with early-stage breast cancer who have a mutation in the BRCA gene are much less likely to die from the disease if they have a double mastectomy, compared with women who have the mutation and only have one breast removed. This is according to a study published in the BMJ.The research team, including Prof.
Annual screening does not reduce risk of death from breast cancer
2/12/2014
According to a study conducted by researchers in Canada and published in the BMJ, annual screening for breast cancer does not reduce likelihood of dying from cancer any more than physical examination or usual care do in women aged 40-59.
Genome analysis reveals the origins of genetic adaptations for high altitude in Tibetans
2/12/2014
Genetic adaptations for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa.
NYU Langone Medical Center researchers have found a biological weakness in the workings of the most commonly mutated gene involved in human cancers, known as mutant K-Ras, which they say can be exploited by drug chemotherapies to thwart tumor growth.

Three doses of HPV vaccine recommended to protect against genital warts
2/11/2014
Two doses of the vaccine against human papillomavirus (HPV) provide good protection against genital warts, but three doses is better according to an extensive register study by researchers at Karolinska Institutet in Sweden. The results are published in the scientific periodical JAMA.Since 2012, girls between the ages of 10 and 18 have been offered free vaccination against HPV.
