Study uncovers bacteria's worst enemy

... of different naturally occurring bacteria used to treat actinide contamination. Actinides are the elements above atomic number 89 and are usually radioactive. The study's results indicate that actinide toxicity is primarily chemical, rather than radiological, and so a bacteria's resistance to radiation do...

Gene therapy cures inherited liver disease in rats

...oints the way to using gene therapy to cure and/or treat a host of other disease that occur because of the lack of genes in this area of the cell. The viral vector itself is important because it has no long term effect. It does not become part of the genetic machinery of the cell and poses no risk of caus...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...esistant to the antibiotics that have been used to treat them, and people infected with these resistant strains have to be treated with alternative antibiotics. For years scientists have been combating drug resistance by coming up with new types of antibiotics, and for years bacteria have been evolving way...

Precise Timing Enabled Pig-to-rat Transplants To Cure Diabetes

...omponents of the pancreas, which are not needed to treat diabetes, develops after cross-species transplantation of such primordia. Even the endocrine part of the pancreas, where insulin is made, is different. "There are no structures similar to the islets of Langerhans, only individual endocrine cells en...

At the molecular level, the predator is the prey

...ive chordates. It is used in low concentrations to treat morphine and heroine addicts. It's also the "zombie" drug used by Haitian voodoo ritualists. Despite its action at the molecular level, the evolution of TTX in some organisms is viewed by ecologists as a defense mechanism. In the case of T. granulos...

Chemical Engineer Kao Explores Antibiotic Synthesis With DNA Chips

...that produces erythromycin, an antibiotic given to treat bronchitis, diphtheria, whooping cough, pneumonia and other conditions. Reverse engineering involves taking something apart to see how it works. For Kao, it means asking how one strain of Saccharopolyspora erythraea produces ten times the erythromyci...

Researchers pioneer new gene therapy technique using natural repair process

..., and while bone marrow transplants can be used to treat the disease, they are not always successful. "SCID is ideal for this sort of therapy because you only need to correct the defect in a small number of immune cells to fix the problem," said Dr. Porteus, assistant professor of pediatrics and biochemis...

Newer imaging techniques may lead to over-treatment

.... "If we see the small clots, we're more likely to treat them; and there are risks to anticoagulant therapy," he said. In fact, "a recent study found a 10 times higher risk of hemorrhagic stroke in patients receiving oral anticoagulant therapy when compared to the general population," Dr. Prologo said. It ...
