Immune systems in breast cancer survivors who suffer from fatigue fail to shut off after therapy

... A small study at UCLA had previously demonstrated abnormalities in immune activation in breast cancer survivors. If researchers could determine the biological factors underlying this activation, and therefore fatigue, they could uncover a biomarker for the condition that could help them predict which patients wou...

The investigators also found physical abnormalities in the brains that mimic some cases of autism, showing that the research animals can be useful in studying the mysterious condition. The finding to be published in the May 4 issue of the journal Neuron confirms recent indications that a mutation i...

"The likelihood of having abnormalities characteristic of AMD on eye exam more than doubled for women who consumed diets with the highest glycemic index, regardless of other factors already known or suspected to increase the risk of AMD, such as age, high blood pressure, cigarette smoking,...

Study says lung cancer overdiagnosis a result of screening

Using a novel and more biologically relevant experimental system, the scientists determined that in pre-B cells, about one out of every 50,000 V(D)J recombinations results in an unexpected, and potentially dangerous, transp...

New egg freezing technique offers hope to hundreds of women

...Rome, Italy, told the conference that a variety of abnormalities became apparent when frozen-thawed eggs were inspected more closely, even in those that appeared undamaged after thawing. In addition, the type and/or concentration of agent that was used to protect the egg during freezing (cryoprotectant agent or CP...
