Researchers found that maternal serum HCG levels are nearly a fifth higher when carrying a girl than a boy less than three weeks into pregnancy. The study also revealed that these early differences are due to the placenta expressing proteins differently in female pregnancies.
Girls from supportive families were almost three times more likely to have used a condom during sex in the past month and less likely to report emotional abuse from their partners. The study also found that girls from unsupportive families were twice as likely to be afraid to talk to their partners about using a condom.
Researchers used DNA arrays to understand macrophage responses, revealing that specific bacterial components can activate the immune system. This knowledge will help design therapeutics with fewer side effects and improve disease treatment.
Researchers at Cold Spring Harbor Laboratory have developed a new technique for carrying out genetic analysis directly in mammalian cells, enabling them to switch off or switch on genes in mouse cells. This ability allows researchers to infer gene function, identify potential cancer therapies, and discover new properties in cells.
Children with chronic illnesses like cancer and diabetes may adapt by repressing emotions, but this defense mechanism can also hinder their ability to manage their illness.
A new theory proposes that modern birds' evolution of flight was driven by their parenting skills, which led them to settle in trees for better protection. This contradicts two leading theories on avian flight and is supported by evidence from Archaeopteryx fossils.
A recent study published in the American Journal of Health Promotion found that blue-collar workers reported less peer pressure and social support to quit smoking compared to white-collar workers. However, both groups reported similar expected social benefits from quitting, such as being rewarded by coworkers for not smoking.
A University of Illinois study suggests that repetitive transcranial magnetic stimulation (rTMS) is a promising alternative to electroconvulsive therapy (ECT) for treating severe depression, with better tolerability and fewer side effects. rTMS showed significant improvement in depression scores, with a 55% reduction in the treatment g...
A study found that military personnel assigned to mortuary duty during the Gulf War experienced increased physical symptoms, with those handling bodies showing the most dramatic increases. The researchers suggest that this may be due to an increased awareness of one's own body or concern about dismissed physical symptoms.
A prospective study found that women with Factor V Leiden mutations had low live birth rates compared to those without the mutation. The research suggests that targeted anti-blood clotting treatment may be beneficial for these women, and screening is recommended.
Researchers found that Egfr signaling is essential for intestinal tumor formation in mice, with 90% fewer polyps developing in one group. The study suggests a potential treatment approach using Egfr inhibitors for advanced colorectal cancers.
