Novel laboratory model reveals clues to how blood starts clotting
October 27, 2006Approach has potential to reveal mechanisms behind variety of reactions within the body
Researchers at the University of Chicago have crafted a simple model for predicting when and where hemostasis - the technical term for blood clotting - will occur. The microfluidic system that they created focuses on the interactions between blood and surfaces patterned to trigger blood clotting. It allows the researchers to separately monitor clotting in both blood plasma and a chemical model.
The researchers, led by National Science Foundation CAREER awardee Rustem Ismagilov, believe the methodology may prove useful in a range of studies, adding a powerful tool for predicting the dynamics of other complex biochemical networks.
The system successfully modeled the workings of a complex biochemical network by showing how the start of clotting depends upon localization of clotting stimuli. The researchers were even able to use the model to predict behavior that they later confirmed with human blood plasma, finding that blood can be exposed to significant amounts of clotting stimuli, such as tissue factor, without initiating clotting.

Your health and Victories in Medical Research. This baby llived because medical science has found a way to prevent hemorrhagic diseases in the newborn. Deficiency of vitamin K results in a subnormal amount of clotting substance in the blood. Thyloqinone, discovered at the Squbb Institute for Medical Research, has exceedingly high vitamin K activity and is a specific for the prevention and control of that hemorrhagic condition. This is a typical example of the way Squibb research is fighting disease and saving lives. Fighting diphtheria. Here you see diphtheria bacilli growing by the billions in special cultures at the Squibb Biological Laboratories. Diphtheria antitoxin is the chief reliance of physicians in fighting this disease. Squibb scientists have contributed to progress in concentrating the antitoxin, thus reducing the dosage volume to the advantage of the patient. ..... 1945 Squibb Ad, A5249A. life19451008 This Item is an original Magazine ad, taken from a vintage magazine of the year indicated. The ad is suitable for framing and displaying in your home or office. The scan of this item was taken through plastic film, however it is an accurate representation of the item.
