FINANCIAL TIES BETWEEN ACAdemic researchers and private industry are currently under intense scrutiny. About $1.5 billion from industry flows into academic institutions annually, and 1 study has shown that 28% of surveyed life sciences faculty report funding from private sponsors. There is growing concern among federal and state agencies and academic institutions that industry sponsorship may i...

The high-resolution solution structure of the inhibitor-free catalytic fragment of human fibroblast collagenase (MMP-1), a protein of 18.7 kDa, which is a member of the matrix metalloproteinase family, has been determined using three-dimensional heteronuclear NMR spectroscopy. A total of 30 structures were calculated by means of hybrid distance geometry-simulated annealing using a total of 3333...

Aim: Injuries due to traffic accidents are frequent in childhood, and they have high mortality and morbidity. Laryngeal injury due to a traffic accident is a rare pathology and might be missed if not suspected. Here we present a laryngeal fracture in a child after a blunt chest trauma during a traffic accident that presented with pneumomediastinum and pneumothorax. Case: A 14-year-old girl was ...

In a porcine preparation of cardiac arrest, we demonstrated that there is a marked paradox of venous acidemia and arterial alkalemia. This paradox is related to decreased clearance of CO2 from the lungs when pulmonary blood flow is critically reduced. Accordingly, increased venous Pco2 rather than metabolic acidosis due to lactic acidosis predominates during the initial 8 min of cardiopulmonary...

Our general concern is with how to integrate a representation of action into an existing set of state constraints. As has been observed in the literature, state constraints implicitly define indirect effects of actions as well as indirectly imposing further preconditions on the performance of actions. Thus, any representation scheme we propose must address the ramification and qualification pro...
