7. Cell Communication and Immunology

Frontiers of Biomedical Engineering (BENG 100) Professor Saltzman talks about cell communication, in particular receptor-ligand interactions that are important in maintaining homeostasis in the body. Different types of receptors and ligands, the nature of their interactions and ways to apply those discussed in the development of drugs (eg Aldopa, Taximofen, beta-blockers). Next, Professor Saltzman speaks of kinases, phosphatases, cyclic AMP and the mechanism of protein-changing states. ThreeCategories of cell communication signals are introduced: autocrine, paracrine and endocrine. Finally, an example of cell communication via regulation / response is submitted on blood sugar levels. Complete training materials are in the Open Yale Courses Web site: open.yale.edu This course was taken in the spring of 2008.

Glycemic Index of Honey and Sugar

Understanding the Glycemic Index of honey and sugar could help you see better your daily consumption of sugar. Do you know how much sugar you take today? Table sugar (chemist calls it "sucrose"), which is made of two simple sugars as glucose and fructose is processed, so that in many foods such as cereals, bread, mayonnaise, jam, peanut butter and ketchup.

The glycemic index is associated with any food, measures how much a given foodaffects blood glucose levels. The lower the rating, the slower the intake and digestion, which means the gradual, healthier infusion of sugars into the bloodstream, whereas a high rating means that blood glucose levels are rapidly increased, and the pancreas will be encouraged to , insulin release to keep the blood - sugar at a constant and safe level, and that inhibits the release of growth hormone, which in turn lowers the immune system. An influx ofSugar in the bloodstream not only affects the body's own blood - sugar balance, secreted insulin promotes the storage of fat and weight gain leading to obesity and cardiovascular disease is linked. Complex carbohydrates such as fruits and vegetables tend to slowly absorbed, reducing the impact on blood - blood sugar level and thus an important component of the diet of those trying to lose weight.

The glycemic index is of particularImportant for diabetics, but also has important implications for the health of the people in general. Low GI diets have been reported to lead to improved insulin responses and blood cholesterol levels. Studies show that honey is low on the glycemic index and therefore provides a long, steady source of energy.

Here is the glycemic index of honey and sugar:

Honey's Glycemic Index: 55
Sucrose's Glycemic Index: 61

And watch what you eat.
