... were dependent upon a unique protein that forms a tiny hole or pore within the membrane of the cells. When oxygen levels are low this pore opens wider to allow the passage of sodium ions into the cell and provides a way in which gasping can occur automatically. The team showed that when this pore was b......or protein interactions, plates containing rows of tiny wells have replaced old-fashioned test tubes. However, trawling for a gene or protein with just the right qualifications may require sorting through millions, or even billions, of possibilities. Instead of wells, the new method, developed by Dr. Dan ...Unique vascular dysfunction in women's heart disease described in major journal supplement

The finding has enabled the researchers to refine a vaccine they previously created against rabies in wildlife, making it safer and more effective.

Antibodies that bind specifically to iNOS also formed clumps of COX-2 and iNOS enzymes bound to each other. The Hopkins team also showed that iNOS first binds to COX-2 and then makes NO. ...Air pollution, high-fat diet cause atherosclerosis in laboratory mice
