Columbia research lifts major hurdle to gene therapy for cancer

Researchers at Columbia University Medical.Center have discovered a way to overcome one of the major hurdles in.gene therapy for cancer: its tendency to kill normal cells in the.process of eradicating cancer cells..In a new study published in the Jan. 25 issue of the Proceedings of the.National Academy of Sciences (PNAS), the researchers demonstrated that.the technique works by incorporating it i...

Columbia study shows widely used artery clearing device does not help patients during heart attack

Interventional cardiologists from Columbia University Medical Center have shown that a commonly used procedure to remove fatty debris from blocked arteries during a heart attack does not improve patient outcomes. .. The procedure, called distal microcirculatory protection, is commonly and successfully used during angioplasty in vein grafts and stenting in carotid arteries. The study, published in...

New bird discovered on unexplored Columbian mountain

A new bird to science was recently discovered on an unexplored mountain range in northern Colombia by a team supported by the BP Conservation Programme. It was named "Yariguies Brush-Finch," with the scientific name Atlapetes latinuchus yariguierum. . The new brush-finch was described by an Anglo-Colombian team of biologists including Thomas Donegan (Fundación ProAves) and Blanca Huertas (Natura...

Columbia scientists determine 3-dimensional structure of cell's 'fuel gauge'

Researchers at Columbia University Medical Center have uncovered the complex structure of a protein that serves as a central energy gauge for cells, providing crucial details about the molecule necessary for developing useful new therapies for diabetes and possibly obesity. A paper published online today in the journal Science details this structure, helping to explain one of the cell's most bas...
