What is ominous octet?
In his 2008 Banting lecture to the American Diabetes Association 68th Scientific Sessions, Prof Ralph DeFronzo proposed an “ominous octet” of eight factors that contributed to the pathophysiology of type 2 diabetes: decreased insulin secretion, decreased incretin effect, increased lipolysis, increased glucose …
What is insulin scholar?
Physiological Role of Insulin Insulin is the pivotal hormone regulating cellular energy supply and macronutrient balance, directing anabolic processes of the fed state. Insulin is essential for the intra-cellular transport of glucose into insulin-dependent tissues such as muscle and adipose tissue.

Type 2 Diabetes Mellitus (T2DM) is characterized by a persistently elevated blood glucose, or an elevation of blood glucose after a meal containing carbohydrate (1) (Table 1).

Why is insulin called hypoglycemic?
As insulin binds to insulin receptors of the target cell and signal transduction, it stimulates the cell to combine glucose transport proteins into its membrane, lead to fall blood glucose levels, hypoglycemic, or “low sugar”, which inhibits β cells to release further insulin through a negative feedback mechanism.
