| Optimistic people have healthier hearts, study finds Posted: 09 Jan 2015 09:35 AM PST Using the American Heart Association's criteria, a study of 5,000 adults found that the most optimistic people had twice the odds of being in ideal cardiovascular health as their pessimistic counterparts.  |
| Breakthrough: Statin treatment reduces risk of cardiovascular disease in women Posted: 09 Jan 2015 06:37 AM PST A large international study has shown conclusively that statin treatment reduces the risk of cardiovascular disease in women. The research confirms that statins are beneficial not only to women who have already had a cardiovascular event such as a heart attack or stroke, but also in those who - whilst they have not yet developed cardiovascular disease -- are at an increased risk of such diseases.  |
| Ritual circumcision linked to increased risk of autism in young boys, research suggests Posted: 09 Jan 2015 06:37 AM PST Circumcised boys are more likely than intact boys to develop autism spectrum disorder before the age of 10, new research suggests. Painful experiences in neonates have been shown in animal and human studies to be associated with long-term alterations in pain perception, a characteristic often encountered among children with ASD.  |
| Cancer biopsies do not promote cancer spread, research finds Posted: 09 Jan 2015 06:37 AM PST A study of more than 2,000 patients has dispelled the myth that cancer biopsies cause cancer to spread. The researchers show that patients who received a biopsy had a better outcome and longer survival than patients who did not have a biopsy.  |
| Skin cancer: New mechanism involved in tumor initiation, growth and progression Posted: 09 Jan 2015 06:35 AM PST The mechanisms regulating the different functions of Twist1 controlling skin tumor initiation, cancer stem cell function and tumor progression have been identified by researchers.  |
| Bacteria could contribute to development of wound-induced skin cancer Posted: 09 Jan 2015 05:47 AM PST A new mechanism by which skin damage triggers the formation of tumors has been discovered by researchers, which could have important therapeutic implications for patients suffering with chronic ulcers or skin blistering diseases.  |
| Tumor-blocking role found for cell regulation molecule Posted: 09 Jan 2015 05:46 AM PST The role of a protein in regulating tumor development has been studied by researchers who have found that it suppresses liver cancer growth in the lab. The investigation has focused on the role of a protein controlled by JNK and p38, known as ATF2, in tumor development.  |
| Novel breast cancer gene found: BCL11A is active in difficult-to-treat triple-negative breast cancer Posted: 09 Jan 2015 05:46 AM PST A gene has been identified that is especially active in aggressive subtypes of breast cancer. The research suggests that an overactive BCL11A gene drives triple-negative breast cancer development and progression.  |
| Study supports link between injectable hormonal contraceptive and HIV risk Posted: 09 Jan 2015 01:56 AM PST Women using depot medroxyprogesterone acetate, commonly known as Depo-Provera or the birth control shot, have a moderately increased risk of becoming infected with HIV, a large meta-analysis of 12 studies involving more than 39,500 women has found. Other forms of hormonal contraception, including oral contraceptive pills, do not appear to increase this risk.  |
| Mental health workers don't recognize their own burnout Posted: 09 Jan 2015 01:55 AM PST Some mental health workers find it difficult to recognize their own burnout and even when they do they struggle to admit it to others, research shows.  |
| More sun means fewer children, grandchildren, Norwegian study finds Posted: 09 Jan 2015 01:55 AM PST A new study shows that increased UV radiation can have an effect on human fertility over generations. On average, the lifespan of children born in years that had a great deal of solar activity was 5.2 years shorter than other children. Children who were born in years with lots of sunshine and who survived were also more likely to have fewer children, who in turn gave birth to fewer children than others. This finding shows that increased UV radiation during years of high solar activity had an effect across generations.  |
