| How does pregnancy reduce breast cancer risk? Posted: 28 Apr 2013 08:04 PM PDT Being pregnant while young is known to protect a women against breast cancer. But why? New research finds that Wnt/Notch signalling ratio is decreased in the breast tissue of mice which have given birth, compared to virgin mice of the same age.  |
| Clarifying the effect of stem cell therapy on cancer Posted: 28 Apr 2013 08:04 PM PDT Injection of human stem cells into mice with tumors slowed down tumor growth, finds new research. Human mesenchymal stem cells, isolated from bone marrow, caused changes in blood vessels supplying the tumor, and it is this modification of blood supply which seems to impact tumor growth.  |
| Residents concerned about health effects of hydrofracking Posted: 28 Apr 2013 08:04 PM PDT Some residents living in areas in Bradford, Co, Pa., near natural gas operations, also known as hydraulic fracturing, are concerned their illnesses may be a result of nearby drilling operations. Twenty-two percent of the participants in a small pilot study surmise that hydrofracking may be the cause of such health concerns as sinus problems, sleeping difficulties, and gastrointestinal problems.  |
| Conversion from 'bad' fat to good fat Posted: 28 Apr 2013 11:49 AM PDT Scientists have shown for the first time that white and brown fat cells can directly interconvert in a living organism from one type to the other. This finding challenges the prevailing belief that white and brown fat cells arise solely from distinct precursor cells. The knowledge will aid in the design of novel strategies to treat obesity.  |
| Obesity may influence heart function through sex hormones Posted: 28 Apr 2013 11:48 AM PDT New research suggests that changes in sex hormones as seen in obesity may have possible effects on the heart. The study suggests effects on heart function in healthy men with artificially raised estrogen levels and artificially lowered testosterone levels to mimic an obese state.  |
| Mapping of cancer cell fuel pumps paves the way for new drugs Posted: 28 Apr 2013 11:48 AM PDT For the first time, researchers have managed to obtain detailed images of the way in which the transport protein GLUT transports sugars into cells. Since tumors are highly dependent on the transportation of nutrients in order to be able to grow rapidly, the researchers are hoping that their study will form the basis for new strategies to fight cancer cells.  |
