Enzyme activity in biological systems is often governed by control mechanisms in which the catalytic properties are made sensitive or insensitive to differences in enzyme or substrate concentration. Here, we report the first supramolecular system where the catalytic activity is made concentration independent through the use of newly designed inhibitor ...

Publisher Summary This chapter provides an overview on autoregulators. Autoregulators, the small diffusible substances, are effective at extremely low concentrations and are required to initiate secondary metabolism or morphogenesis, or both. The actinomycete autoregulators, A-factor, is most extensively studied. The hormone-like control exerted by it

To Autoregulate or Not to Autoregulate—That is No Longer the Question
Seminars in Pediatric Neurology, 2009In the late 1970s, high cerebral blood flow was perceived as a cause of intracranial hemorrhage in the preterm infant. Intracranial hemorrhage was diagnosed by computed tomography and ultrasound found to be frequent not only in babies who died. Hemorrhage was soon linked to cerebral palsy in survivors. The analogy was hypertensive hemorrhagic stroke in

THE AUTOREGULATION OF THE MICROCIRCULATION
Acta Medica Scandinavica, 1975Abstract. The paper reviews August Krogh's contribution to capillary physiology stressing his formulation of useful new concepts such as “tissue cylinder model”, capillary intermittency and the intimate matching of capillary perfusion and cellular metabolism.

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.

Mitotic Autoregulation: a Reply [PDF]
Nature, 1970 THE 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.

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.
