Islet Sheet 101: The basics

Sunday, July 18th, 2010

Question: I was wondering if you can explain your project in layman’s terms. I don’t understand what islets are; I do get that the sheets will hold something to help with blood sugars, but will that be human- or pig-based? What type of freedom will diabetics have? Will they be able to eat whatever they want, or not worry about lows? Will there be side effects? What makes your ideas better than other companies experimenting with islets? How will it work? What about the hormone Amylin: will that be present? Sorry for the stupid questions.

A Breakthrough in Pig Islet Transplantation?

Tuesday, July 6th, 2010

In the thread from my last essay I was asked my opinion of a recent paper from Washington University St. Louis showing progress in islet xenotransplantation. My quick read from the online abstract was positive. This week I decided to get the whole article and comment on it in more detail.

The authors claim “This is the first report of prolonged engraftment and sustained normalization of glucose tolerance following transplantation of porcine islets in nonimmune-suppressed, immunocompetent rodents. The data are consistent with tolerance induction….” This is important because tolerance induction could permit transplantation of islets of Langerhans without immune suppression drugs and without encapsulation — it’s the ideal solution to the immune suppression problem. Did they show true tolerance induction? After studying the paper, I choose the Scottish verdict: “Not proven.”

Recent Progress in the Solving Diabetes Project

Sunday, June 20th, 2010

Hanuman Medical Foundation’s grant support for the Solving Diabetes Project began in the fall of 2008. From a standing start we are now getting interesting and significant results in treatment of experimental animal diabetes. Here is a brief report on these developments.

Questions from a reader

Monday, June 7th, 2010

One of the pleasures of writing for solvingdiabetes.org is I get feedback on the thoughts of a group of interested diabetics in the world.  It lets me know what is less than clear on our web sites.  I recently received the following questions from MK.

The Cure is Five Years Away (and always will be)

Sunday, May 23rd, 2010

Newsweek Magazine states on its cover: “Desperately Seeking Cures: Medical research isn’t making progress rapidly enough.” Their key observation is that the academic medical research world is structured with incentives that perversely favor glamourous discoveries, not cures. The article does not cover diabetes research. I decided that today I would apply it to my area of interest, juvenile diabetes. So this is today’s question: Why is there no cure for type 1 diabetes?

Prevention of Hypoglycemia

Monday, May 10th, 2010

On the plane yesterday I felt a tickle in my mind — prickly skin, a feeling of greater alertness, a touch of fear. Could my blood sugar be dropping? A quick check, and I find it is 78. My hypoglycemia awareness kicked in exactly as my blood sugar passed through 80 on the way down. A few M&Ms and the fear went away in a few minutes. If I had not learned about my sugar drop, and done nothing, eventually…….

Smart Insulin: As Smart as Islets?

Wednesday, April 28th, 2010

Recently Elizabeth Snouffer published an interview with me at Diabetes24-7. During the discussion after, Elizabeth noted that a number of people liked the Smart Insulin approach, and she asked me to talk about how it compared with the Islet Sheet. Today I feel I was not completely fair to Smart Insulin and wanted to write a bit more.
The idea is attractive: formulate insulin so that the rate of insulin release increases as glucose goes up.
Insulin stores islets in the form of crystals, which contain both the protein insulin and the ion zinc (yes, the same zinc found in mineral supplements that is …..

Dogs, Pigs and Diabetes

Monday, April 12th, 2010

Medicine learned of type 1 diabetes early with the observation of people who seemed to eat food and make honey out of it (diabetes mellitus means “honey passing through”). It was induced in animals for the first time in 1889 when Oskar Minkowski surgically removed the pancreas of a dog. Thus did the dance of knowledge of diabetes in humans and animals begin.

Athletic Diabetes

Sunday, March 14th, 2010

We think famous people are different from us because they are celebrities and we are not. On the web you can easily find long lists of celebrities, living and dead, who suffered from type 1 diabetes. Nick Jonas (Jonas Brothers) is famous for this. Interviews with diabetics are becoming a staple of Olympic coverage. When I was diagnosed my mind went to Mary Tyler Moore, the rare celebrity (at the time) who was open about diabetes and taking insulin as part of her life.

Scott’s Tips for T1D Management

Monday, March 1st, 2010

While we wait for the functional cure we have management with injected insulin. I have been managing my own type 1 diabetes for over thirtyyears through many changes in the tools available. I have developed a few rules. So here, especially for my T1D readers, are tips on the things that get me through.
