| Medicinal chemists modify sea bacteria byproduct for use as potential cancer drug Posted: 31 Aug 2011 06:01 PM PDT Scientists have modified a toxic chemical produced by tiny marine microbes and successfully deployed it against laboratory models of colon cancer. More work is needed before a human treatment can be considered, but it appears to be a novel way to kill tumor cells.  |
| Study of metabolites reveals health implications from small molecules Posted: 31 Aug 2011 12:53 PM PDT Researchers have discovered 37 new genetic variants associated with concentrations of metabolites in the blood: many of these match variants associated with diseases such as kidney disease and type 2 diabetes. The team looked for genetic influences on levels of more than 250 compounds in blood, including lipids, sugars, and amino acids. The effects of variants discovered in genome-wide association analyses can be modest and biological understanding poor: this new approach can overcome these problems.  |
| Resistance to antibiotics is ancient Posted: 31 Aug 2011 12:53 PM PDT New research findings show antibiotic resistance is a natural phenomenon that predates the modern clinical antibiotic use. The breakthrough will have important impact on the understanding of antibiotic resistance.  |
| A step toward a saliva test for cancer Posted: 31 Aug 2011 12:53 PM PDT A new saliva test can measure the amount of potential carcinogens stuck to a person's DNA -- interfering with the action of genes involved in health and disease -- and could lead to a commercial test to help determine risks for cancer and other diseases, scientists report.  |
| Families of drugs developed from bacteria, fungi, snails, leeches and other such species Posted: 31 Aug 2011 05:15 AM PDT Whether you have a mild headache or you are running a fever, there is a high chance that the drug that is used to treat you comes from nature.  |
