Drug Offers Alternative to Surgical Treatment After Miscarriage

...rthritis. Misoprostol is now more commonly used to induce labor, as it stimulates contractions of the uterus. In recent years, physicians have begun prescribing misoprostol in place of surgery to women who have experienced a miscarriage. Until the current study, however, no large-scale studies have been un...

Improving the potential of cancer vaccines

... of clinical trials, the data suggest that you can induce (cancer) antigen-specific immune responses, but such responses are too weak and transient to eradicate tumor cells." The answer lies in a group of cells called CD4+ regulatory T cells (Treg for short). These cells have the ability to suppress the bo...

Why are coyotes getting more aggressive?

...earchers also will develop and test ways to try to induce coyotes to fear humans without harming them. "We need to determine what people are doing, for example, to encourage coyotes into their yards, such as feeding dogs or cats outdoors and leaving the dishes out or leaving animals out at night," says Cur...

Female volunteers prepare for a second 'bedrest'

...th their feet slightly higher than their heads, to induce the same conditions in the body as those experienced during long periods of weightlessness. The volunteers were divided into three groups of four in order to study the effects of special measures designed to counter the loss of muscle, fluid and bone...

A new molecule discovered in the battle between plants and disease

...deficient fad3-2 fad7-2 fad8 mutant plants did not induce the proAtPep1, PDF1.2 or PR-1 genes, indicating that AtPep1 signaling involves the octadecanoid pathway. AtPep1 induction of defense genes in excised Arabidopsis leaves was inhibited by DPI, implicating the generation of H2O2 in the signaling pathway...

For first time, brain cells generated in a dish

...ts collected cells from mice and used chemicals to induce them to differentiate. During the process, they snapped images of the cells every five minutes for up to 30 hours and compiled the images into movies. Traditional ways to attempt neurogenesis have been unable to so closely duplicate the natural proce...

Compound from Chinese medicine shows promise in head and neck cancer

... are exquisitely sensitive to (-)-gossypol. We can induce cell death in 70 percent to 90 percent of cells. This is a very impressive induction of cell death. It's because we are targeting the pathways these cells need to survive," says study author Thomas Carey, Ph.D., co-director of the Head and Neck Oncol...
