Therapeutic strategies for pregnant women with lupus
The disease, which has no cure, operates much like an allergic reaction gone awry: When activated, the immune system also attacks the body's healthy cells, tissues, and organs, causing inflammation and producing a host of symptoms that, though unique to each person, are universally called flares. A highly gender-biased disease, lupus afflicts females some nine times more than … [Read more...]
Pulse waves measured at the wrist uncover often-missed artery changes in menopausal women

Vast majority of dietary supplements don’t improve heart health or put off death, study finds
In a massive new analysis of findings from 277 clinical trials using 24 different interventions, Johns Hopkins Medicine researchers say they have found that almost all vitamin, mineral and other nutrient supplements or diets cannot be linked to longer life or protection from heart disease. Although they found that most of the supplements or diets were not associated with … [Read more...]
Sperm may offer the uterus a ‘secret handshake’
Why does it take 200 million sperm to fertilize a single egg? One reason is that sperm, when they arrive in the uterus, face a bombardment by the immune system. Perhaps, says molecular anthropologist Pascal Gagneux, many are needed so that some will survive. On the other hand, there may be a benefit to culling so many sperm. "I'm a lonely zoologist in a medical … [Read more...]
Study finds key metabolic changes in patients with chemotherapy-associated cardiotoxicity
