Advances in Kidney Disease and Health
Potassium homeostasis is essential for maintaining the normal resting membrane potential of excitable cells. Yet daily dietary potassium typically far exceeds total extracellular potassium, thus the body has elegant strategies to shift potassium into cells promptly after a meal and then the kidneys efficiently excrete potassium.

Annual Review of Physiology, 2007
Iron is needed by all mammalian cells but is toxic in excess. Specialized transport mechanisms conduct iron across cellular membranes. These are regulated to ensure homeostasis both systemically in living organisms and within individual cells. Over the past decade, major advances have been made in identifying and characterizing the proteins involved in

Current Opinion in Neurobiology, 2013
Research on sleep homeostasis aims to answer the question: how does the brain measure the duration and intensity of previous wakefulness in order to increase the duration and intensity of subsequent sleep? The search of regulatory factors has identified a number of potential molecules that increase their concentration in waking and decrease it during ...

WIREs Systems Biology and Medicine, 2010
AbstractMetazoan life is dependent upon the utilization of O2 for essential metabolic processes and oxygen homeostasis is an organizing principle for understanding metazoan evolution, ontology, physiology, and pathology. Hypoxia‐inducible factor 1 (HIF‐1) is a transcription factor that is expressed by all metazoan species and functions as a master ...

Annual Review of Medicine, 1991
This review describes a homeostatic model for the regulation of nutrient intake and the control of partitioning between fat and protein storage. With this homeostatic model, the clinical abnormalities of energy storage such as obesity, anorexia nervosa, and cancer cachexia are examined and potential mechanisms suggested.

Potassium balance is regulated by appropriate changes in potassium excretion in the distal portion of the nephron. By contrast, potassium intake, absorption and proximal renal reabsorption do not show regulatory variation. Extracellular potassium concentration, which is a critical factor in membrane polarization, may at times vary in a direction ...
