GLOBAL AND LOCAL STABILITY FOR A NON-LINEAR HYPERBOLIC SYSTEM MODEL FOR THE ROLE OF STEM CELLS IN PHYSIOLOGICAL HOMEOSTASIS

by Laura Di, Bernardo, Donatella Donatelli
"... Abstract. In this paper we propose an existence and uniqueness the-ory for the solutions of a system of non-linear hyperbolic conservation laws, structured in age and maturity variables, representing a tissue en-vironment. In particular we are interested in the investigation of the role of stem cell ..."

Renal Physiology Osmotic Homeostasis

by John Danziger, Mark L. Zeidel
"... Alterations inwater homeostasis can disturb cell size and function. Althoughmost cells can internally regulate cell volume in response to osmolar stress, neurons are particularly at risk given a combination of complex cell function and space restriction within the calvarium. Thus, regulating water b ..."

G: Autophagy in the pathogenesis of disease

by Beth Levine, Guido Kroemer - Cell
"... Autophagy is a lysosomal degradation pathway that is essential for survival, differentiation, development, and homeostasis. Autophagy principally serves an adaptive role to protect organisms against diverse pathologies, including infections, cancer, neurodegeneration, aging, and heart disease. Howev ..."

Cardiovascular Homeostasis

by Kunio Ohta, Akihiro Yachie
"... l l The study of vascular biology has provided strong evidence for the role that free radical attack plays in the pathogenesis of cardiovascular diseases. The endothelial cell (EC) dys-function that results from exposure to oxidative stresses, such as oxidized LDL, in¯uences vascular cell gene expre ..."

"... # The Author(s) 2009. This article is published with open access at Springerlink.com Abstract Assembly of an inward rectifier K + channel pore (Kir6.1/Kir6.2) and an adenosine triphosphate (ATP)-binding regulatory subunit (SUR1/SUR2A/SUR2B) forms ATPsensitive K + (KATP) channel heteromultimers, wide ..."

Temperature, physiology, and the ecology of reptiles

by Raymond B. Huey - Biology of the Reptilia , 1982
"... There is a great mass of information available concerning temperature as an ecological factor, but its actual operation is sometimes difficult to evaluate. A. HISTORICAL VIEWS OF TEMPERATURE AND REPTILIAN ECOLOGY The physiological differences of reptiles from other tetrapods have important ecologica ..."

1 Integrative concept of homeostasis: translating physiology into medicine

by Ivan Spasojević
"... To truly understand living systems they must be viewed as a whole. In order to achieve this and to come to some law to which living systems obey, data obtained on cells, tissues and organs should be integrated. Because there are no such laws yet, there is usually a long path for physiological findin ..."

The concept and accompanying equations of homeostasis presented here are aimed to develop biological laws and to bridge this gap between physiology and medicine. The concept of homeostasis takes into account energy input
