Study finds vegetable-derived compound effective in treating triple-negative breast cancer

Arlington, Va. — A new compound created from a rich source in vegetables including broccoli and brussel sprouts has been developed to combat triple-negative breast cancer (TNBC). This research is being presented at the 2012 American Association of Pharmaceutical Scientists (AAPS) Annual Meeting and Exposition, the world's largest pharmaceutical sciences meeting, in Chicago, Ill., on Oct. 14 – 18, during Breast Cancer Awareness Month.

Novel chewing gum formulation helps prevent motion sickness

Arlington, Va. — A new prototype for medicated chewing gum has been developed for motion sickness that may offer many advantages over conventional oral solid dosage forms. About 33 percent of people are susceptible to motion sickness in mild circumstances and 66 percent are affected in more severe conditions. This research is being presented at the 2012 American Association of Pharmaceutical Scientists (AAPS) Annual Meeting and Exposition in Chicago, Ill., Oct. 14 – 18, an international event anticipating more than 8,000 attendees.

Daily multivitamins reduce risk of cancer in men

Boston, MA – A daily multivitamin can help a man reduce his risk of cancer, according to new research from Brigham and Women's Hospital (BWH). The first-of-its kind study will be presented October 17 at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research and published online the same day in the Journal of the American Medical Association.

Multivitamin use among middle-aged, older men results in modest reduction in cancer

CHICAGO – In a randomized trial that included nearly 15,000 male physicians, long-term daily multivitamin use resulted in a modest but statistically significant reduction in cancer after more than a decade of treatment and follow-up, according to a study appearing in JAMA. The study is being published early online to coincide with its presentation at the Annual American Association for Cancer Research Frontiers in Cancer Prevention Research meeting.

An epigenetic difference in twins explains different risk of breast cancer

Monozygotic twins have the same genome, that is, the same DNA molecule in both siblings. Despite being genetically identical, both twins may have different diseases at different times. This phenomenon is called "twin discordance". But how can people who have the same genetic sequence present different pathologies and at different ages? The explanation partly lies in the fact that the chemical signals added in the DNA to "switch off" or "switch on" genes can be different. These signals are known as epigenetic marks.

Searching for a silver bullet: Measuring biodiversity to inform species conservation

Athens, Ga. – Ecologists in the University of Georgia Odum School of Ecology have found that evolutionary diversity can be an effective method for identifying hotspots of mammal biodiversity. In a paper published Oct. 17 in the journal Proceedings of the Royal Society B, they report that evolutionary diversity can be an effective proxy for both the sheer number of species as well as their characteristics and ecological roles. Their findings could help conservation organizations better protect threatened species across the globe.

Study questions feasibility of entire genome sequencing in minutes

Amsterdam, October 17, 2012 – The claim that nanopore technology is on the verge of making DNA analysis so fast and cheap that a person's entire genome could be sequenced in just minutes and at a fraction of the cost of available commercial methods, has resulted in overwhelming academic, industrial, and global interest.

Extreme 'housework' cuts the life span of female Komodo dragons

Extreme 'housework' cuts the life span of female Komodo Dragons

An international team of researchers has found that female Komodo Dragons live half as long as males on average, seemingly due to their physically demanding 'housework' such as building huge nests and guarding eggs for up to six months.

The results provide important information on the endangered lizards' growth rate, lifestyle and population differences, which may help plan conservation efforts.

Hard evidence grows for including meditation in government-sponsored health programs

More people still die from cardiovascular disease than any other illness. Dubbed the number one killer and the silent killer, modern medicine has been researching and incorporating complementary and alternative approaches to help treat and in some cases reverse and hopefully prevent this health problem at an earlier stage of the disease. One of those modalities is meditation.

Active surveillance provides a viable alternative to surgery for small kidney masses

Active surveillance of small kidney masses is a safe and effective alternative to immediate surgery, with similar overall and cancer specific survival rates, according to a study published in the November issue of the urology journal BJUI.

The technique is primarily used to treat elderly patients who have complex health issues or decline surgery. But researchers from the Department of Urology at Churchill Hospital, Oxford, UK, say that the results of their study suggest that active surveillance could safely be extended to other selected patients.

Military safety is blowing in the wind

A command doctrine used by the US military and NATO designed to warn personnel of Nuclear, Chemical and Biological (NBC) hazards could be overly conservative and degrade war fighting effectiveness or, under certain conditions, risk lives because it is susceptible to changes in wind direction and speed that happen in periods shorter than its two-hourly updates.

New insights into how genetic differences influence breast cancer risk from low-dose radiation

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have identified tissue mechanisms that may influence a woman's susceptibility or resistance to breast cancer after exposure to low-dose ionizing radiation, such as the levels used in full-body CT scans and radiotherapy.

The research could lead to new ways to identify women who have higher or lower risks of breast cancer from low-dose radiation. Such a predictive tool could help guide the treatment of cancer patients who may be better served by non-radiation therapies.

Vitamin D supplements may benefit lupus patients

A new clinical study published in BioMedCentral's open access journal Arthritis Research and Therapy provides preliminary evidence that vitamin D supplementation could be considered an immunomodulatory agent for systemic lupus erythematosus (SLE), a debilitating autoimmune disease characterized not only by skin, joint, neurological and renal symptoms, but also by inflammation of tissue linings in the body.

Cochrane Review finds no benefit from routine health checks

Carrying out general health checks does not reduce deaths overall or from serious diseases like cancer and heart disease, according to Cochrane researchers. The researchers, who carried out a systematic review on the subject for The Cochrane Library, warn against offering general health checks as part of a public health programme.
