Postmenopausal women at higher risk of stroke than they think

A new study by researchers at NYU Langone Medical Center and colleagues found that traditional risk factors for stroke - such as high cholesterol - are not as accurate at predicting risk in postmenopausal women as previously thought. Instead, researchers say doctors should refocus their attention on triglyceride levels to determine which women are at highest risk of suffering a devastating and potentially fatal cardiovascular event.

Scientists uncover genes that govern male and female behaviors

Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how? Now a team of scientists at the University of California, San Francisco (UCSF) has uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern several specific types of male and female behaviors in mice.

Strong link between triglyceride levels and ischemic stroke in older women

In a surprising finding with significant implications for older women, researchers at Albert Einstein College of Medicine of Yeshiva University and NYU School of Medicine have found that high levels of triglycerides (blood fats) are the strongest risk factor for the most common type of stroke in older women – more of a risk factor than elevated levels of total cholesterol or of low-density lipoprotein (LDL) cholesterol.

New combination clinical trial may improve outcome for cancer surgery patients

The week before and two weeks after surgery are a critical period for the long-term survival rate of cancer patients. Physiological and psychological stresses caused by the surgery itself can inhibit the body's immune responses, heightening vulnerability to tumor progression and spreading.

Link between maternal nurturing and size of hippocampus in healthy children

School-age children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress. The new research, by child psychiatrists and neuroscientists at Washington University School of Medicine in St. Louis, is the first to show that changes in this critical region of children's brain anatomy are linked to a mother's nurturing.

New research gains increased respect for contraceptive method

Imagine a contraceptive that could, with one or two painless 15-minute non-surgical treatments, provide months of protection from pregnancy. And imagine that the equipment needed were already in physical therapists' offices around the world.

Reason for language development delay in boys – Testosterone: Study

For the new study researchers collected umbilical cord blood from 767 Australian newborns and tested for testosterone. Newborn boys are exposed to 10 times the levels of testosterone before birth, compared to girls. Sex hormones, like testosterone, are known to play a key role in shaping how the brain develops. Then, the researchers evaluated the children’s language skills when they were 1, 2 and 3 years of age.

Women feel pain more than men: Study

A new study showed that women experience more intense pain than men. The study published in the Jan. 23 issue of the Journal of Pain, further suggests that greater effort is needed to recruit women into studies in order to determine the reasons for this gender difference. The Stanford University School of Medicine investigators examined pain scores from tens of thousands of patients in the United States.

Exposure to phthalates may increase risk of obesity in young children

Researchers from the Children's Environmental Health Center at The Mount Sinai Medical Center in New York have found an association between exposure to the chemical group known as phthalates and obesity in young children - including increased body mass index (BMI) and waist circumference.

External stimuli control hormonal regulation of our eating behavior

Max Planck researchers have proven something scientifically for the first time that laypeople have always known: the mere sight of delicious food stimulates the appetite. A study on healthy young men has documented that the amount of the neurosecretory protein hormone ghrelin in the blood increases as a result of visual stimulation through images of food.

Study explains gender-related incidence of liver cancer

Men are four times more likely to develop liver cancer compared to women, a difference attributed to the sex hormones androgen and estrogen. Although this gender difference has been known for a long time, the molecular mechanisms by which estrogens prevent -- and androgens promote -- liver cancer remain unclear.

Gastric bypass superior to lap banding finds study

A new study evaluates the best option in terms of weight loss surgery for those who need it. Researchers found gastric bypass patients lose more weight than gastric banding patients and keep it off longer. Even though banding is a simpler operation, nearly half of those patients were still obese after six years.
