Results Based on the Ackerman's published data, we estimated the key parameters by applying R-based iterative computer programs. As a result, the theoretically simulated curves perfectly matched the experimental data points.
Our model showed that the estimated parameters, computed frequency and period values, were proven a good indicator of diabetes. Conclusion The present paper introduces a computational algorithm to biomedical problems, particularly to endocrinology and metabolism fields, which involves two coupled differential equations with four parameters describing the glucose-insulin regulatory system that Ackerman proposed earlier.
The enhanced approach may provide clinicians in endocrinology and metabolism field insight into the transition nature of human metabolic mechanism from normal to impaired glucose tolerance. While an estimated Diabetes can cause serious health complications including blindness, heart disease, kidney failure, stroke, nerve damage, and lower extremity amputations. Consequently, diagnosis, treatment, control and prevention of diabetes, are extremely critical in the current medical era.
How Insulin Works
Thus, insulin hormone can no longer be produced. Type II diabetes formerly called non-insulin-dependent diabetes mellitus, NIDDM, or adult-onset diabetesa more widespread metabolic disorder, is primarily characterized by insulin resistance, relative insulin deficiency and hyperglycemia.Part 2.1 - Entity relationship model diagram in dbms in hindi introduction and basics syllabus
However, in both type I and type II cases, the human body loses its ability to regulate blood sugar, which causes a significantly negative effect on the patients' quality of life or even be potentially fatal. It is a common knowledge that blood glucose concentration in normal humans is maintained within a precise and stable range.
Many external and internal factors affect the level of blood glucose such as food intake, rate of digestion, excretion, exercise, sleep, and psychological state. These individual or combinational influences constantly alter the physiological processes that regulate plasma glucose level.

For instance, if blood glucose is elevated, after a regular meal i. The secreted insulin, then, leads to the uptake of glucose from the blood into the liver and other cells, such as muscle cells. Thus, blood glucose level will eventually go down to the normal range.

On the other hand, blood glucose level may decrease imminently due to muscular activity, particularly when food intake is confined. These cells then release glucagon that act on the cells of the liver to initiate the release of glucose.

This results in blood glucose level elevating back to the normal range. Briefly, these islet-cell arguments establish the fact that the capacity to lower blood glucose depends on the responsiveness of the pancreatic beta-cells to glucose and the sensitivity of the glucose utilized by tissues to the released insulin.
Furthermore, a shortage of plasma insulin and low glucose tolerance, resulting in a serious inability to lower blood glucose, will cause insulin resistance, which is the key symptom underlying the potential development of diabetes. However, to tackle diabetes disease and obesity problems, clinicians and researchers are now turning to mechanism-based mathematical models to reach quantitative diagnoses of glucose intolerance and insulin resistance, and also to predict the likely outcomes of therapeutic interventions.
Their ultimate goal is to develop a mathematical model that can be used to accurately predict the outcomes and most successful treatment options for people who have diabetes.
The fundamental nature of a good mathematical model must be simple in design and exhibit the basic properties of the real system that we are attempting to simulate and understand. All well-developed models should be validated and tested against empirical data. In a practical sense, the quantitative comparisons of the model to the real system should lead to an improved mathematical model. This ensures that the glucose in the blood will plateau at a healthy level and not go too low. The absence of insulin in the blood is also a signal that the body hasn't eaten for a while and should tap fat stores instead of glucose for its energy needs.
Though its job is being a hormone, insulin is also a protein, manufactured by the body using information written in the genes. The beta cells are the only cells in the body with the natural capacity to make insulin. This specialization means that the beta cells are the body's last and only hope for regulating blood glucose levels on its own.
Insulin in Diabetes Diabetes develops when the beta cells fail to produce enough insulin to keep blood glucose levels in a healthy range. In type 1 diabetesthe beta cells are destroyed by the body's own immune system gone haywire. In type 2cells are resistant to insulin, and the beta cells fail to produce enough of the hormone to compensate.
The goal of diabetes treatment is to normalize blood glucose levels by either increasing levels of insulin in the body or sensitizing the body to insulin. All people with type 1 and some with type 2 require treatment with insulin to control blood glucose. There are two basic kinds of insulin used to manage diabetes: Mealtime insulin works fast and, as the name suggests, is taken just before eating to deal with the subsequent surge in blood glucose as food is digested. Background insulin is usually taken once a day and keeps blood glucose down between meals.
While both mealtime and background insulins are essentially the same protein, almost identical to the version made by the body, the medicines are formulated differently in the lab to speed or slow their absorption, respectively. Oral medications for type 2 diabetes work by either boosting the production of insulin by the beta cells or making the body less resistant to insulin.
Insulin can't be taken orally because, as a protein, it would be destroyed by digestive enzymes. Instead, it must be put into the body's tissues by syringe, pen, or pump. All of these approaches deliver insulin just under the skin. From there, it diffuses to the bloodstream, where it goes to work. Researchers are developing better and easier ways to deliver insulin and more closely match the body's need for it.
