Scientists seek answers on what activates deadly anthrax spores

...went off. The group also would like to understand another closely related bacterium, Bacillus cereus, one strain of which can produce anthrax-like symptoms. The research team includes Conn Mallett, Ph.D., Derek Parsonage, Ph.D., graduate students Carleitta Paige, Jamie Wallen, and Tim Colussi, and senior r...

Dinosaur DNA? New Patent Covers Degraded DNA recovery

...graded. "We hope this gives criminal investigators another tool to re-open cold cases or revisit crime scenes, stringing together strands of detached DNA into a genetic trail that could solve a crime or exonerate the falsely accused," says Dr. Ensley. This patent is part of a scientific progression that beg...

Leukemia Drug Breakthrough Study In New England Journal Of Medicine

...ncluding leukemias and small cell lung cancer. In another finding of the same study, all the patients with the 5q deletion who became transfusion independent also went into cytogenetic remission, meaning that the chromosome abnormality disappeared. List, a professor of interdisciplinary oncology at the Uni...

Gene therapy converts dead bone graft to new, living tissue

...eeds. The process works both ways, fortunately, as another set of cells, called osteoblasts, rebuilds the bone when the body has excess calcium. In an average year, a healthy person may remove and rebuild 10 percent of his or her bone structure. This process of teardown and rebuilding is triggered in the de...

Antibiotic Resistant Bacterium Uses Sonar-like Strategy to “See?Enemies or Prey

...eam found that this toxin ismade whenever there is another cell type in the environment near thebacterium, such as a human blood cell. They discovered how thesebacteria know when other cells are present, and respond accordingly.In the laboratory, the team found that Enterococcus releases twosubstances into t...

Novel Therapy Tested in Mice Could Chase Away Cat Allergies

...hat it might also work in people. Scientists made another set of mice allergic to cats by injecting them with cat protein and an immune system booster. These mice became “actively allergic?to cats: their reactions to cat allergen would be comparable to reactions in a cat-allergic person. Scientists injected...

An HIV Protein Plays a Surprising Role in Gene Activation

...vator (Gal4-VP16), a transcriptional enhancer, and another viral activator called E1a—the authors show that what's true for yeast also holds for mammals, or at least for the human cell lines investigated here. Each effector was required for PIC assembly, which was in turn required to activate transcription. ...

New imaging method gives early indication if brain cancer therapy is effective, U-M study shows

...rapy or a combination. Three weeks later, they had another diffusion MRI. After finishing their treatment, the participants underwent standard MRI to determine whether their tumor responded to the therapy. After three weeks ?more than two months before the final MRI scan ?researchers found significant diffe...

Enzyme shown to help protect genomic stability

...bp10 appears to work similarly and in concert with another enzyme called Sir2, which removes acetyl molecules from histones. Sir2 has also been associated with promoting genomic stability, and some studies have linked it intriguingly to the aging process. Some studies, for example, have suggested that low-ca...

"Therefore, the migrastatin analogues must be working on something upstream of those two important steps," Dr. Huang said. Dr. HuangÕs next important step is moving these analogues into clinical trials. "We'r...

In both cases, the sounds were totally different from sounds made by other normal calf, adolescent and adult African elephants and very similar to recorded sounds that were common in the auditory environment of the subjects of this...

Genetically modified natural killer immune cells attack, kill leukemia cells

In another application, NK cells could be obtained from a patient while in remission and then reinfused after genetic modification if the patient suffers a resurgence of the leukemia. "We look forward to seeing this strategy being added to the management of ch...

UCSD researchers maintain stem cells without contaminated animal feeder layers

... human feeder layers were developed but this added another measure of complexity to the culture system, Hayek noted. In recent studies in Wisconsin and Massachusetts, new feeder layers were developed, but they did not entirely eliminate the use of animal products. In the Hayek study, the animal-derived feede...
