The wing of the aeroplane is designed to create a difference in the momentum in the air ahead of the wing as it passes over it to create lift.

In patients, with diabetes, the body faces a hyperglycemic condition, which prompts the cells to make high amounts of AR, thereby producing high amounts of sorbitol which is impermeable in the cells and causes osmotic stress. Additionally, AR als…
