Scientists discover a new way for preventing liver metastases

Scientists in Switzerland have discovered a way to block the growth of human colon cancer cells, preventing the disease from reaching advanced stages and the development of liver metastases. The research, published today in EMBO Molecular Medicine, shows that blocking the so-called Hedgehog-GLI pathway can prevent the growth of tumours, metastatic lesions and cancer stem cells, the cells thought to lie at the root of cancer growth.

Barrier-focused intervention program to increase colonoscopy attendance

In view of low attendance rate for colonoscopy screening for colorectal cancer (CRC), it is necessary to establish effective intervention methods to increase colonoscopy compliance. Many studies have reported that subjective or objective barriers prevent high-risk subjects from undergoing colonoscopy examination, which indicates that barrier-focused intervention might be effective. However, such barrier-focused intervention has not been reported in China.

New technique for diabetes treatment may be in the offing

An exploration of the molecular links between insulin resistance and inflammation may have revealed a novel target for diabetes treatment, say scientists at the John G. Rangos Sr. Research Center, Children's Hospital of Pittsburgh of UPMC. Their findings were published earlier this month in the online version of Diabetes, one of the journals of the American Diabetes Association.

New website launched for comparing mortality risks by gender, age, cause of death and geographic region

A new Web site, www.DeathRiskRankings.com, developed by researchers and students at Carnegie Mellon University, allows users to query publicly available data from the United States and Europe, and compare mortality risks by gender, age, cause of death and geographic region. The Web site not only gives the risk of dying within the next year, but it also ranks the probable causes and allows for quick side-by-side comparison between groups.

Recurrence rate of patients with node-negative gastric cancer can be reduced

Many studies favor an extended lymphadenectomy at the time of a potentially curative gastrectomy for node-positive gastric cancer, and the risk of long-term death tends to decrease when the number of resected lymph nodes increases to about 25. However, few studies have assessed the relative contribution of the total number of resected lymph nodes to the outcome of patients with node-negative gastric cancer.

Endocyte receives payment for the advancement of epothilone-folate anti-cancer agent

Endocyte, Inc., a cancer drug discovery and development company, today announced it has received a milestone payment from Bristol-Myers Squibb Company (NYSE: BMY). This payment was triggered by the commencement of a Phase II clinical trial for an epothilone-folate anti-cancer agent identified through the collaboration between Endocyte and Bristol-Myers Squibb scientists.

Study reveals poor body satisfaction and increased risk of disordered weight control behaviors among 10 to 11 year old children

A study of 4254 Canadian schoolchildren has shown a direct association between BMI and satisfaction with their body shape. The research, published in the open access journal BMC Public Health, shows a linear response for girls, who were happiest when thinnest, and a U-shaped response for boys, who were unhappy when they were too skinny or too fat.

Lack of imagination and aversion to commercial risk are the biggest threats to Australia’s medical innovation

Australia could be a world leader in medical innovation but commercial risk aversion and parochialism are holding the industry back, a leading venture capitalist will argue at a public lecture and debate at the University of New South Wales next week (Monday, 31 August).

Herbalscience research throws light on causes of allergic rhinitis

Most people might think of nettle as simply a common and aggressive weed that can sting and cause skin irritation. But nettle has also been used for hundreds of years to treat seasonal allergies and other inflammatory diseases, although the precise nature of its anti-inflammatory effect was unknown. Now, scientists with HerbalScience have identified specific bioactives in nettle leaf extracts that inhibit in vitro receptors and enzymes known to be key in generating symptoms of allergic rhinitis, or hay fever.

Studies suggest that serrated polyps can be precursors of colon cancers

Serrated colorectal polyps include the subgroups hyperplastic polyps, sessile serrated polyps (also called sessile serrated adenomas), and serrated adenomas. Recent studies have found that serrated polyps share molecular features with a subgroup of colon cancers, leading to the hypothesis that serrated polyps can be precursors of cancer through a hyperplastic polyp to serrated adenoma to cancer sequence.

Virginia Tech researchers to help pre-diabetic adults begin resistance training for preventing diabetes

Systematic, progressive resistance training - also called strength training - is a safe and efficient way for middle-aged and older adults to improve their health. A Virginia Tech led research team that includes experts in behavior, exercise, physiology, and medicine is designing a program to help pre-diabetic adults begin and, most important, maintain resistance training in order to prevent diabetes.
