Researchers unravel DNA tangles and enzyme seamstresses

...cations in designing new drugs to treat cancer and infectious diseases as uncontrolled DNA linking and tangling often result in cell death. "The exciting part is that these seemingly abstract physical principles we work with can be useful some day to tie up DNA in cancer cells and kill them off," says U of T ...

...lls," said Jeffrey M. Bergelson, M.D., a pediatric infectious diseases specialist at The Children's Hospital of Philadelphia. "We found new steps in the virus life cycle." Dr. Bergelson's study, co-authored with Carolyn B. Coyne, Ph.D., also of Children's Hospital, appears in the Jan. 13 issue of the journal C...

New test to detect rare proteins in blood

...used as a diagnostic test to determine exposure to infectious agents, such as HIV, by identifying antibodies present in a blood sample. The sensitivity of detecting molecules by the new method, called FACTT, short for Florescent Amplification Catalyzed by T7-polymerase Technique, is five orders of magnitude (...

Gut protein found to protect against infection and intestinal breakdown

...stine, a major barrier against the infiltration of infectious microorganisms. That's no small task; if the innermost lining of the small intestine alone were unfolded, it would be the size of a tennis court. When there's no bile in the intestine, as happens in people with obstructive jaundice or in those who r...

UCLA paper examines how one disease may prevent another

...vents another. His findings suggest that genetic, infectious and metabolic influences should be considered when looking for treatments, particularly in regard to HIV/AIDS. "Clinical observations of disease-versus-disease interactions have led to an understanding of the mechanisms of several diseases," Stiehm ...

A case of mistaken molecular identity

... mimicry occurs when a molecule that is part of an infectious agent resembles a molecule native to the body. Eventually, the immune system begins to mistake the native molecule for the invader. Levin's investigations revealed that an intra-cellular T. cruzi protein resembles the beta1-adrenergic receptor on t...

Inflammation and drugs to control this activity studied in a variety of tumors sites

Inflammation cuts both ways. When invaded by an infectious agent, for example, the body calls on the forces of inflammation to fight and defeat the intruder. But when the biochemical processes of the immune system are either misdirected or chronically turned on, inflammation can lead to adversity, including ...
