| Nanoparticles refined for more accurate delivery of cancer drugs Posted: 19 Jan 2012 01:32 PM PST A new class of nanoparticles, synthesized to prevent premature drug release, holds promise for greater accuracy and effectiveness in delivering cancer drugs to tumors.  |
| 'Pulverized' chromosomes linked to cancer? Posted: 19 Jan 2012 01:32 PM PST Researchers have mapped out a mechanism by which micronuclei could potentially disrupt the chromosomes within them and produce cancer-causing gene mutations. The findings may point to a vulnerability in cancer cells that could be attacked by new therapies.  |
| Investigators achieve important step toward treating Huntington's disease Posted: 19 Jan 2012 01:32 PM PST Researchers have developed a technique for using stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington's disease, a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death.  |
| How immune cells move against invaders Posted: 19 Jan 2012 01:32 PM PST Scientists have discovered the unexpected way in which a key cell of the immune system prepares for battle. The finding, they said, offers insight into the processes that take place within these cells and could lead to strategies for treating conditions from spinal cord injury to cancer.  |
| Color-coding, rearranging food products improves healthy choices in hospital cafeteria Posted: 19 Jan 2012 01:32 PM PST A simple program involving color-coded food labeling and adjusting the way food items are positioned in display cases was successful in encouraging more healthful food choices in a large hospital cafeteria.  |
| Another clue in the mystery of autism Posted: 19 Jan 2012 11:33 AM PST A study of discordant twins -- twins in which one has autism spectrum disorder and one doesn't -- finds the lower birth weight twins are more than three times as likely to have ASD than heavier twins. Though genetic effects are of major importance, say researchers, the study suggests a non-genetic influence associated with birth weight may contribute to development of ASD.  |
| How protein in teardrops annihilates harmful bacteria: Novel technology reveals lysozymes have jaws Posted: 19 Jan 2012 11:33 AM PST A disease-fighting protein in our teardrops has been tethered to a tiny transistor, enabling scientists to discover exactly how it destroys dangerous bacteria. The research could prove critical to long-term work aimed at diagnosing cancers and other illnesses in their very early stages.  |
| Manganese may have potential in neutralizing deadly Shiga toxin Posted: 19 Jan 2012 11:33 AM PST Researchers have discovered that manganese, an element commonly found in nature, might provide a way to neutralize the potentially lethal effects Shiga toxin. New results could pave the way for future research aimed at creating an inexpensive treatment for infections caused by bacteria that produce the Shiga toxin. Currently there is no treatment for such infections that afflict more than 150 million people each year, resulting in more than one million deaths worldwide.  |
| Chemists unlock potential target for drug development Posted: 19 Jan 2012 10:39 AM PST A receptor found on blood platelets whose importance as a potential pharmaceutical target has long been questioned may in fact be fruitful in drug testing, according to new research.  |
| Study finds potential key to immune suppression in cancer Posted: 19 Jan 2012 10:38 AM PST In a study investigating immune response in cancer, researchers have found that interaction between the immune system's antigen-specific CD4 T cells and myeloid-derived suppressor cells (MDSC) – cells that play a major role in cancer-related immune suppression – dramatically change the nature of MDSC-mediated suppression. By contrast, the same effect was not observed when MDSCs interacted with the immune system's CD8 T cells.  |
