You have probably had blood drawn from a superficial vein in your arm, which was then sent to a lab for analysis. Some of the most common blood tests—for instance, those measuring lipid or glucose levels in plasma—determine which substances are present within blood and in what quantities....

A negative feedback system operates between cortisol and CRH: As cortisol levels decrease, CRH is increased. CRH directly stimulates ACTH, and ACTH directly stimulates cortisol. As cortisol levels increase, CRH release is decreased. In addition to the feedback loop mentioned previously, the ...
Closed-loop control of blood glucose levels in critically ill patients A closed-loop control system was constructed for automatic intravenous infusion of insulin to control blood sugar levels (BSL) in critically ill patients. ... F Chee,T Fernando,PVV Heerden - 《Anaesthesia & Intensive Care》 ...
In addition, some of the vasoconstrictor hormones, such as angiotensin II and endothelin, stimulate local production of vasodilator prostaglandins, including PGE2 and PGF2α, resulting in a negative feedback loop between vasoconstrictors and prostaglandins (Schlondorff 1993). Interrupting prostaglandin ...
We sought to test the feasibility and efficacy of bihormonal closed-loop blood glucose (BG) control that utilizes subcutaneous (SC) infusion of insulin and glucagon, a model-predictive control algorithm for determining insulin dosing, and a proportional-derivative control algorithm for determining gluc...
It represents the catalytic subunit of TORC1 and TORC2, two distinct complexes linked by a negative feedback loop, able to regulate different functions and downstream targets [27].The above described results indicated that both complexes are activated in skin-derived SS cells; however, the ...
In a closed-loop control approach to managing type 1 diabetes, glucose sensors placed under the skin continuously monitor blood sugar levels, triggering the release of insulin from an implantable insulin pump as needed. The aim of this closed-loop insulin delivery system is improved control of blo...

Diabetes is a chronic metabolic disorder characterized by elevated blood glucose levels, posing significant health risks such as cardiovascular disease, and nerve, kidney, and eye damage. Effective management of blood glucose is essential for individuals with diabetes to mitigate these risks. This study...
