Assessment of renal autoregulation
American Journal of Physiology-Renal Physiology, 2007The kidney displays highly efficient autoregulation so that under steady-state conditions renal blood flow (RBF) is independent of blood pressure over a wide range of pressure. Autoregulation occurs in the preglomerular microcirculation and is mediated by two, perhaps three, mechanisms.

Autoregulation of Glucose Production
Physiology, 2000Glucose itself regulates endogenous glucose production independently of changes in glucoregulatory hormones. In addition, acute stimulation of gluconeogenesis does not increase net glucose production. This indicates autoregulation of glucose production. Glucokinase plays a role in this process by allowing hepatic glucose sensing.

Mitotic Autoregulation: a Reply
Nature, 1970THE essence of my model, of which the paradigm is Bertalanffy's model of constant cell size in microorganisms1, is that the geometry of the population is critical with important implications for organ growth characteristics, especially in development.

Cerebrovascular and brain metabolism reviews, 1990
Autoregulation of blood flow denotes the intrinsic ability of an organ or a vascular bed to maintain a constant perfusion in the face of blood pressure changes. Alternatively, autoregulation can be defined in terms of vascular resistance changes or simply arteriolar caliber changes as blood pressure or perfusion pressure varies.

Cerebral Autoregulation and Syncope
Progress in Cardiovascular Diseases, 2007Whatever the pathogenesis of syncope is, the ultimate common cause leading to loss of consciousness is insufficient cerebral perfusion with a critical reduction of blood flow to the reticular activating system. Brain circulation has an autoregulation system that keeps cerebral blood flow constant over a wide range of systemic blood pressures. Normally,

RENIN AND RENAL AUTOREGULATION
The Lancet, 1968Abstract A renin/renal-autoregulation hypothesis is proposed and supported by the evidence gained by some of the foremost workers in the field. I depends on an increased sodium concentration in the lumen of the early distal tubule activating a sodium-dependent carrier to transport renin from the granules of the juxtaglomerular apparatus into the ...
