Background Recruitment of stem cells to sites of tissue injury constitutes an important mechanism aimed at tissue repair and regeneration. However, it is not clear how the diabetic milieu affects the viability of endogenous stem cells.

A computer-based proportional-integral (PI) controller has been developed to control arterial oxygen levels in mechanically-ventilated animals. Arterial oxygen saturation is monitored using a non-invasive oximeter and control is effected by adjusting inspired oxygen fraction. The performance of the feedback system is sensitive to the open-loop gain so that the desired transient specifications can...
