| Letrozole may help women with polycystic ovary syndrome become pregnant Posted: 09 Jul 2014 03:21 PM PDT The drug letrozole results in higher birth rates in women with polycystic ovary syndrome (PCOS) than the current preferred infertility treatment drug, according to a nationwide American study. PCOS affects 5 to 10 percent of reproductive-age women and is the most common cause of female infertility. Women affected have excessive levels of the hormone androgen, have infrequent periods, develop small cysts on the ovaries and have trouble conceiving.  |
| My brother's keeper: How siblings teach one another about the world Posted: 09 Jul 2014 08:55 AM PDT While researchers have long known that brothers and sisters teach each other about the world, most of their observations about this have been made in a lab setting. A new study has investigated a step further by observing how children interact in their natural habitat: their homes. Through the study, investigators not only confirmed that teaching occurs naturally and spontaneously, but that both older and younger siblings initiate learning activities. What's more, siblings acting as teachers use a variety of instructional techniques during these informal lessons.  |
| Think fun when exercising and you'll eat less later Posted: 09 Jul 2014 06:59 AM PDT If you think of your next workout as a 'fun run' or as a well-deserved break, you'll eat less afterward, research has shown. However, if you think of it as exercise or as a workout you'll later eat more dessert and snacks, to reward yourself. For beginning or veteran exercisers, the bottom line is this: "Do whatever you can to make your workout fun. Play music, watch a video, or simply be grateful that you're working out instead of working in the office," said one author.  |
| Nearly 50 percent of grade 12 students in Ontario report texting while driving Posted: 09 Jul 2014 06:59 AM PDT An ongoing survey of Ontario students in grades seven to 12 reveals a number of significant behavioral trends, including an alarming number of young people who are texting while driving. More than 80 per cent of students visit social media sites daily, with about one in ten spending five hours or more on these sites daily. One in five students play video games daily or almost daily with males being almost four times as likely as females to do so.  |
| Mode of delivery following perineal tear, recurrence rate in subsequent pregnancies Posted: 09 Jul 2014 06:59 AM PDT There is an increased risk of severe perineal tearing during childbirth in women who had such a tear in a previous delivery, suggests a new study. Most women tear to some extent during childbirth and in some women the tear may be more extensive. The report found that among women who had a vaginal delivery at second birth, the rate of a severe tear was 7.2% in women with a tear at first birth, compared to 1.3% in women without, a more than five-fold increase in risk.  |
| Posted: 09 Jul 2014 06:56 AM PDT Children who live on farms that produce milk run one-tenth the risk of developing allergies as other rural children. According to researchers, pregnant women may benefit from spending time on dairy farms to promote maturation of the fetal and neonatal immune system.  |
| Cinnamon may be used to halt progression of Parkinson's disease, study suggests Posted: 09 Jul 2014 06:52 AM PDT Using cinnamon, a common food spice and flavoring material, can reverse the biomechanical, cellular and anatomical changes that occur in the brains of mice with Parkinson's disease (PD), neurological scientists have found. "This could potentially be one of the safest approaches to halt disease progression in Parkinson's patients," the study's lead researcher said.  |
