But in people with juvenile diabetes, the pancreas does not produce insulin and blood sugar levels can get dangerously high.

The pancreas is an organ that in healthy people secretes insulin to convert glucose into energy.

Researchers adjusted their computer algorithm to the slower insulin absorption rate and on a repeat experiment blood glucose was tightly controlled in all of the subjects.

But the remaining five other patients did not respond as quickly to the insulin infusion and developed low blood sugar because the computer continued to administer medication.

"because the fat mass can induce changes that are metabolically bad, like an increase in glucose or insulin, also an increase in fat,blood fats, like triglycerides or cholesterol."

"The insulin pumps exist, the continuous glucose monitors exist.

The computer program continuously takes in data from a glucose monitor inserted into a patient's vein and calculates the dose of artificial insulin that needs to be infused through an insulin pump.

Failure to maintain tight control of glucose levels - by measuring blood sugar with a meter and compensating with doses of insulin - can result in serious health complications, including blindness, kidney failure and heart disease.

The pump developed by researchers is a double pump - in addition to insulin, it automatically secretes glucagon, a hormone that taps glucose reserves in the liver, raising blood sugar levels when they get too low, a condition called hypoglycemia.

"We're bringing back to people with Type 1 diabetes not only the proper amount of insulin dosed correctly into the right amount, but also this ability to provide a little bit of glucagon after meals, if the insulin dosing turned out to be a little excessive.

Although we run it on a laptop so that we can monitor its operation, the algorithm itself doesn't require a lot of computer power and could easily be run from a chip that has the capabilities of one that's already in insulin pumps or in cell phones."
