Computer Simulation Accurately Predicts Blood Vessel Growth

Bioengineers from the University of Utah created a computer simulation that accurately maps blood vessel growth. This can help in the further treatments to provide better blood supply to skin grafts and implanted ligament and tendon, as well as tissues damaged by diabetes and heart attack.

The image on the left in green, show real blood vessels growing in culture while the right image in red, is the computer simulation of the blood vessel growth. The simulation is based on the study and use of real blood vessels from rats.

Additionally, the top images show real and simulated blood vessel growth when vessel fragments are placed in an "extracellular matrix" of collagen with a relatively low density. The middle and bottom images show how blood vessel growth is impeded when they are placed in collagen matrix with medium and higher density, respectively.

The physical and mechanical properties of the collagen are highlighted by the simulation showing that a denser collagen matrix makes it hard for blood vessels to form a network. By accurately predicting the growth and spread of the blood vessels, bioengineers can prepare implantable tissues that already contain blood vessels that match a patient's blood vessel structure.

This technology can provide better treatment by replacing damaged heart tissues, reconstructing ligaments and tendon, and skin grafts to stimulate blood flow to promote healing of diabetic ulcers.

Study On Coffee Improving Blood Flow In Small Blood Vessels Presented at AHA Scientific Sessions 2013

Coffee can significantly help small blood vessels in improving blood flow. Researchers from the University of the Ryukyus in Okinawa, Japan presented the study at the American Heart Association’s Scientific Sessions 2013.

The study based on observations done on 27 adults showed a 30% increase in blood flow over a period of 75 minutes compared to those who drank decaffeinated coffee. It should be noted that the test subjects were not regular coffee drinkers.

Coffee is the most consumed beverage in the world. It is the primary source of caffeine which stimulates the central nervous system. It makes the brain more alert and active. The US FDA treats caffeine both as a drug and a food additive. It is legal and unregulated in nearly all parts of the world.

Aside from the latest study, regular consumption of coffee has been linked to other health benefits such as a lowered risk of heart disease and stroke, improved function of large arteries, and improved brain metabolism in diabetic patients.
