Maslinic acid provides a natural defense against colon cancer

Researchers from the University of Granada and the University of Barcelona have shown that treatment with maslinic acid, a triterpenoid compound isolated from olive-skin pomace, results in a significant inhibition of cell proliferation and causes apoptotic death in colon-cancer cells. Maslinic acid is a novel natural compound and it is able to induce apoptosis or programmed death in human HT29 colon-cancer cells via the intrinsic mitochondrial pathway. Scientifics suggest this could be a useful new therapeutic strategy for the treatment of colon carcinoma.

Scientists call up stem cell troops to repair the body using new drug combinations

Scientists have tricked bone marrow into releasing extra adult stem cells into the bloodstream, a technique that they hope could one day be used to repair heart damage or mend a broken bone, in a new study published today in the journal Cell Stem Cell.

Spirituality is key to kids' happiness

To make children happier, we may need to encourage them to develop a strong sense of personal worth, according to Dr. Mark Holder from the University of British Columbia in Canada and his colleagues Dr. Ben Coleman and Judi Wallace. Their research shows that children who feel that their lives have meaning and value and who develop deep, quality relationships – both measures of spirituality – are happier. It would appear, however, that their religious practices have little effect on their happiness.

A life with pain -- new study examines the experiences of older people

It's debilitating, isolating and can lead to severe depression — yet pain is widely accepted as something to be expected and regarded as 'normal' in later life. Now a new study from The University of Nottingham examines older people's experiences of pain and how best Government, the NHS and social care agencies can address the issue.

Sequence matters in droughts and floods

When extremes of drought and flood come in rapid succession, the extent of damage to vegetation may depend in part on the sequence of those events, according to a new study published in The American Naturalist.

Hormone therapy associated with reduced colorectal cancer risk

PHILADELPHIA – The combination of estrogen plus progestin, which women stopped taking in droves following the news that it may increase their risk of breast cancer, may decrease their risk of colorectal cancer, according to a report published in the January issue of Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.

Chemopreventive agents in black raspberries identified

PHILADELPHIA – A study published in Cancer Prevention Research, a journal of the American Association for Cancer Research, identifies components of black raspberries with chemopreventive potential.

Researchers at the Ohio State Comprehensive Cancer Center found that anthocyanins, a class of flavonoids in black raspberries, inhibited growth and stimulated apoptosis in the esophagus of rats treated with an esophageal carcinogen.

Metabolic syndrome risk for veterans with PTSD

Veterans with post-traumatic stress disorder (PTSD) are more likely to have metabolic syndrome than veterans without PTSD. New research published in the open access journal BMC Medicine has shown that after controlling for other factors such as depression or substance abuse, there is a significant association between metabolic syndrome and PTSD.

Metabolic syndrome is composed of a cluster of clinical signs including obesity, high blood pressure and insulin resistance. It has been associated with diabetes, cardiovascular morbidity and mortality.

Ahead of the games: Test will catch sports cheats on new endurance drugs

Avoiding detection just got harder for drug cheats who try to use a particular range of untested, but potentially enhancing, compounds. In the past, tests have been developed once a drug is known to be in circulation. Now a German research team has developed tests for a class of drugs that they believe could be used in the near future.

Metabolic syndrome a risk for veterans with PTSD

Veterans with post-traumatic stress disorder (PTSD) are more likely to have metabolic syndrome than veterans without PTSD, according to a study led by Pia Heppner, Ph.D., psychologist with the University of California, San Diego School of Medicine and Veterans Affairs of San Diego, VA Center of Excellence for Stress and Mental Health (CESAMH). The study will be published online January 8 by the journal BMC Medicine.

Gene abnormality found to predict childhood leukemia relapse

Scientists have identified mutations in a gene that predict a high likelihood of relapse in children with acute lymphoblastic leukemia (ALL). Although the researchers caution that further research is needed to determine how changes in the gene, called IKZF1 or IKAROS, lead to leukemia relapse, the findings are likely to provide the basis for future diagnostic tests to assess the risk of treatment failure. By using a molecular test to identify this genetic marker in ALL patients, physicians should be better able to assign patients to appropriate therapies.

Mountaineers measure lowest human blood oxygen levels on record

The lowest ever levels of oxygen in humans have been reported in climbers on an expedition led by UCL (University College London) doctors. The world-first measurements of blood oxygen levels in climbers near the top of Mount Everest, published in this week's New England Journal of Medicine (NEJM), could eventually help critical care doctors to re-evaluate treatment strategies in some long-term patients with similarly low levels of blood oxygen.

Women's access to donated kidneys declines with age, particularly compared with men

Younger women have equivalent access to kidney transplants compared with their male counterparts, but older women receive transplants much less frequently than older men, according to a study appearing in the March 2009 issue of the Journal of the American Society Nephrology (JASN). The results suggest that steps are needed to ensure that women are provided with equal opportunities to receive kidney transplants as they age.

Repeat C-section before 39 weeks raises risk of neonatal illness

BIRMINGHAM, Ala. – Women choosing repeat cesarean deliveries and having them at term but before completing 39 weeks gestation are up to two times more likely to have a baby with serious complications including respiratory distress resulting in mechanical ventilation and NICU admission.
