A type 1 diabetic mystery is why do some Type 1s get complications and others seem to never get them? A massive Japanese study of Type 1 diabetics found that those with fulminant diabetes developed complications much faster and more severely than those with non-fulminant diabetes.

The difference between fulminant and non-fulminant is the speed and intensity at which the disease develops. Fulminant Type 1 diabetes typically develops suddenly with near total loss of beta cell function. This type of diabetes is confirmed with testing c-peptide levels. Non-fulminant type 1 diabetes has residual c-peptide levels that eventually taper to undetectable. Sometimes this is seen through many years of the Honeymoon Period.

This study may be the antithesis of conventional wisdom for preventing complications. Staking all hopes on blood sugar control is heavily optimistic. Yes controlling blood sugar does lessen the workload for existing beta cells, and thus extends the lifespan of each beta cell. Research suggests that c-peptide offers protection to beta cells, both from apoptosis (cell death) and encourages new cell growth. This new cell growth applies to beta cells and other cells of the body that endure long-term Type 1 diabetes complications.

Diabetics are instructed that maintaining normal blood sugars is the Holy Grail of preventing long-term complications. Yes and no. The truth is controlling your blood sugar will not allow complications of Type 1 diabetes to develop as quickly, presuming you still had some level of beta cell function upon diagnosis (i.e., c-peptide). That doesn't sound like a reward as much as it does a delayed punishment. I'd like c-peptide with my insulin, please. It's off the à la carte menu? That's fine - serve it up! I want to thank Klausen for bringing this study to my attention.

Ed Hinerman, a life insurance specialist with the Hinerman Group, was posed an interesting challenge recently. For years he has successfully found affordable life insurance for many adults with type 1 diabetes, but he had never been asked about life insurance for children with Type 1 diabetes until now.

After speaking with underwriters in the top 40 or so companies, he found a discernible lack of interest due to lack of data. Companies would say that they couldn't consider someone with type 1 diabetes until they were either age 15 or age 20. A peer in the industry told Ed the knee jerk reaction was because insurance companies haven't done mortality studies on children. They simply don't have any data upon which to base the pricing for products. Uh oh!! That coupled with the fact that there really isn't any financial incentive for them to study and create products for a relatively small market that would produce relatively low premium, kind of sets the tone. Well, now the war has been defined and the battles are becoming clearer.

When Ed contacted the ADA for assistance in this matter - hold your breath (it's a shocker!) - they turned a cold shoulder on a diabetic's need. What if the diabetic's parents were doing what so many families do - and trying to buy a whole life policy to help pay for their kids college someday? It's really not fair! Here's where fair begins -- Ed asked me to gather some facts it will take to get the insurance companies attention. Does anybody have any idea of the mortality rate of children after being diagnosed with type 1 diabetes?

Bottom line. Life insurance companies make big money and for them to cut and run from children just because it might not make them more big bucks, or because they really haven't done their homework and aren't interested in doing it, isn't acceptable. Game on! I hope we can make a good showing, at the very least - hit one out of the park for the fans. Thanks for inviting me to play, Ed!

Oramed is developing a soft gel insulin capsule for the treatment of diabetes. The company has recently announced it the successful completion of its clinical trial demonstrating the safety and efficacy of the oral insulin gel capsule.

The pills were shown to reduce blood sugar, with no significant adverse effects. The insulin used in the gel caps is a generic brand of human insulin. The duration of the insulin is similar to Regular. But the most beautiful thing about these gel caps is that they reintroduce the liver into glucose metabolism, thereby reducing the likelihood of dangerous lows associated with injected insulin and oral medications. This could blow away the necessity of blood sugar testing because you are regulating glucose metabolism in the liver, like a person without diabetes.

Up until now, the idea of insulin pills or tablets was inconceivable due to the fact that insulin, when swallowed, breaks down in the digestive system. Oramed's patented technology overcame the problem of digestion as well as permeability to the intestine. The company's goal is for the completion of formal Phase 1 studies in the US by mid-2008. Sign me up!

I contacted Novo Nordisk back in March to tell them about the remarkable effects C-peptide had on reversing complications of Type 1 diabetes. I asked if they would bring the drug to market. A mass of excitement overwhelmed me when I learned about C-peptide missing from insulin all these years. The response from Novo? No thanks, it's not one of our targets. Targets, eh?

C-peptide is a byproduct of the production of insulin. In Type 1 diabetics, the level of C-peptide eventually becomes undetectable due to the body not making any insulin of its own. Long-term complications of diabetes frequently develop despite insulin therapy and optimal blood glucose control. C-peptide could quite possibly be the missing link in perfect diabetes control. I sent the following document to Novo Nordisk and asked them to make C-peptide available to reverse and ameliorate renal and nerve dysfunction for Type 1 diabetics. Read the document and see for yourself the eye-popping beneficial results C-peptide offers Type 1 diabetics. I received it directly from Dr. Wahren, lead researcher for C-peptide.

After 5 months consideration, Novo called me back. They said C-peptide is not a target for their company. I understand and now Levemir is not a target in my diabetes control, either. For all the Type 1 diabetics out there controlling your sugars with insulin not really made with you in mind -- do you understand why Novo does not wish to develop this critically important treatment? I guess insulin is good enough, right? Wrong. It's a tough job but somebody's got to do it. Just not Novo. When you are in the business of diabusiness -- no thank you says so much about what could potentially hurt your business.

For those of you who do not know her yet - consider today your lucky day!! She is Amy Tenderich and her site, Diabetes Mine, is a force to be reckoned with in the diabetes online community. What do I mean? When Amy speaks - anybody who's anybody in the diabetes online community listens.

A few months ago she posted an open letter to Steve Jobs, which was wildly discussed in the blogosphere and media. She invited gadget designers to rise to the challenge of creating sleeker, cooler, consumer-oriented medical devices for people with diabetes. Not only did she get the diabetes blogosphere stirring - but the minds of entrepreneurs storming, as well.

Amy motivated a San Francisco-based company to react in a universal remote control sort of way. Adaptive Path has designed The Charmr, a prototype of a continuous glucose monitor combined with an insulin pump, universally controlled by a device that looks to be no bigger than a USB stick! I strongly encourage everybody to checkout Amy's blog with all the details (including reader feedback) and the YouTube video on the Charmr. Bravo Amy!!

We looked at the cell in a series of six articles and now we are moving into the fascinating world of tissues. A tissue is a group of cells with similar structure and function. The tissue then contributes to the functioning of the organs in which it is found. Epithelial tissue exists at the body surface where it lines the skin and various organs such as the mouth, nose and other body cavities. It is also found at the lining of the respiratory, reproductive and urinary tracts. All blood vessels are also lined with epithelial tissue. Epithelial tissue is divided into different types.

The first type of epithelial tissue is the covering and lining epithelium. It forms the epidermis of the skin and the outer covering of some internal organs as well as the inner lining of blood vessels, ducts and body cavities. It is arranged by layers and cell shapes. The layers are: simple epithelium, stratified epithelium and pseudostratified columnar epithelium. The cell shapes are: Squamous, cuboidal, columnar and transitional.

Simple squamous epithelium: It consists of a single layer of flat cells that resembles a tiled floor. It is located in the lining of the blood vessels, lining of body cavities and part of the kidney tubules. Its functions are protection and absorption.

Simple cuboidal epithelium: The cuboidal shape of the cells in this tissue is obvious when the tissue is sectioned and viewed from the side. It is located in the secretory portion and ducts of some glands and part of the kidney tubules. Its functions are secretion and protection.

We start with the cell, because so much of what happens to us when we get sick, and how we get healthy again, can be explained by what happens on a cellular level. The cell is extremely complex and I will only touch on the basics in these posts, but at least we can have a rudimentary understanding.

We have discussed cell membranes (May 24), as well as cell organelles (May 31). On , June 7,we discussed the cellular transport mechanisms and on June 14, we discussed the cell nucleus. On June 21 we discussed cell division and today we will end the series on the cell with a short look at protein synthesis.

Although cells synthesize many chemicals to maintain homeostasis, they are mainly devoted to synthesizing large numbers of proteins. Proteins are used as enzymes and as structural materials in the cells. Many proteins are retained in the cell for intracellular use. Some proteins are used to assemble cellular structures such as the plasma membrane, the cytoskeleton and other organelles. There are many specialized human proteins that are exported and function in cellular activities. For example, protein makes up the hormone insulin, the ligaments and tendons of joints, the hair, skin, and nails of the body.

One of the features of a cell is it's ability to reproduce independently. In somatic cell division, a cell undergoes a nuclear division called mitosis. Reproductive cell division is the mechanism that produces gametes. This process consists of a two step division called meiosis.

In this post we will look at the process of mitosis. Each of us began life as one cell, a fertilized egg. Each of us now consists of billions of cells produced by the process of mitosis. In mitosis one cell with the diploid number of chromosomes (46, except in chromosomal abnormalities) divides into two identical daughter cells, each with the diploid number of chromosomes. Mitosis is a continuous process compromised of a series of events. This series of events are divided into different stages called: prophase, metaphase, anaphase, telophase and cytokinesis. Prior to these events interphase occurs, which is divided into 3 phases of its own.

As with the other parts of the cell, this can be a short discussion or a series of articles in and of themselves. I have decided to stay very basic and not discuss each component separately.

With the exception of mature red blood cells, human cells have a nucleus and some, like skeletal muscle cells, have more than one. The nucleus is composed of three main parts, the nuclear envelope, the nucleolus and the chromatin.

The nucleus is separated from the cytoplasm by a double membrane (nuclear envelope) that have lipid bilayers like the plasma membrane. The outer membrane of the nuclear envelope is continuous with the rough endoplasmic reticulum (ER). It controls the movement of substances between the nucleus and the cytoplasm through nuclear pores -- channels that perforate the nuclear envelope. Small molecules can diffuse through the nuclear pores, but larger molecules, like ribonucleic acid (RNA), need to use active transport facilitated by carrier proteins. The other structural element of the nucleus is the cellular lamina, a mesh-work that adds support, much like the cytoskeleton supports the cell as a whole.

We have discussed cell membranes (May 24), as well as cell organelles (May 31). Before we look at the nucleus of the cell, I would like to do a short post on some of the mechanisms for molecular movement across the cell membrane. Transport across the cell membrane is important to understand, because a lot of the newer research seems to focus on this aspect.

Living cells constantly interact with the external environment, like tissue or blood. In order to do that, materials must move through the plasma membrane, taking in some substances and secreting or excreting others. There are several methods by which movements can occur: diffusion, osmosis, facilitated diffusion, active transport, filtration, endocytosis and exocytosis. We will look at each of these briefly.

Structure of cells

A cell has three basic parts:

1) Plasma membrane: A membrane lies at the border of cells and consists of lipids and proteins. See my post of 23 May on the cell membrane

2) Cytoplasm: All the cellular contents between the plasma membrane and the nucleus and can be further divided into the Cytosol and Organelles. We will discuss the organelles in today's post.

3) Nucleus: Technically an organelle, but usually considered separately because of its numerous and diverse functions.

Organelles

Organelles are specialized structures that evolved to perform specific functions. We could probably discuss each organelle in a separate post, because each one has it's own characteristic shape and function. i decided to keep this very basic and just list the different organelles, what they look like and what their basic function is. We will also just look at the "famous" organelles. There are other organelles, but the ones we discuss will give us a good understanding of what goes on inside the cell.

Membrane

A membrane lies at the border of the cells. It consists of lipids and proteins.

Phospholipids (one of the three classes of membrane lipids) are formed into what is called a lipid bilayer. This occurs because it is amphiphilic (containing both hydrophobic and hydrophilic properties). The hydrocarbon tails of the molecule are hydrophobic (water repelling) and its polar head is hydrophilic (water loving). As the plasma membrane faces watery solutions on both sides, its phospholipids accomodate this by forming a phospholipid bilayer with the hydrophobic tails facing each other. Picture a row of heads facing the outside of the cell -- which contains water -- with the tails facing in and another layer of the heads facing the inside of the cell with the tails facing in.
