Glucose Concentration in Subcutaneous Extracellular Space

Diabetes Care, 1993
OBJECTIVE To compare the subcutaneous glucose sensor measurements with two reference methods. Previous studies provide conflicting findings about the real glucose concentrations in subcutaneous tissue. Some suggest substantially lower concentration, whereas others measure proportionally higher glucose concentrations

The extracellular space and matrix of gliomas

Acta Neuropathologica, 2005
Changes in the properties of extracellular space (ECS)--its volume, shape, and composition--play an important role in influencing the biological behavior of brain tumors. Experimental methods allowing assessment of the volume and geometry of ECS by means of analyzing the diffusion of molecules within ECS have revealed a dramatic increase in the ECS ...

Tracking extracellular space in the brain

Science, 2016
Neuroscience Extracellular space takes up a large percentage of the brain. Its size changes with the sleep-wake cycle but also during brain development and normal aging, as well as under pathological conditions such as neurodegeneration. Godin et al. injected near-infrared luminescent carbon nanotubes into rat brains and tracked their diffusion in the ...

Extracellular superoxide dismutase (SOD3): An antioxidant or prooxidant in the extracellular space?

2020
Superoxide dismutase 3 (SOD3 or EC-SOD) is the only scavenger of superoxide in the extracellular space allowing for the catalyzed dismutation of the superoxide radical into hydrogen peroxide. The activity and distribution of the enzyme are regulated at several levels, suggesting the need for balanced activity in the extracellular space.

Extracellular space determination in gallbladder mucosa

Biochimica et Biophysica Acta (BBA) - General Subjects, 1975
Abstract Sucrose seems to be the best marker of the extracellular space in gallbladder mucosa. Inulin space is always smaller than sucrose space and the difference seems to be due to a sweeping-away effect in the intercellular channels as metabolic inhibitors and ouabain reduce it. Mannitol space continuously increases and this substance is likely to

The Extracellular Space of the Brain

1965
Publisher Summary This chapter discusses the extracellular space of the brain. Some 10–15 % of the volume of the brain behaves as though it were extracellular, in the sense that under appropriate conditions an extracellular “tag,” such as sucrose, will come into equilibrium with it. The appropriate condition is that the sucrose should be presented by

The extracellular space of rat intestine ?in vivo?

Pfl�gers Archiv European Journal of Physiology, 1972
The extracellular space (ECS) of rat jejunum, ileum and colon were determined in “in vivo” condition both by means of a continuous perfusion technique and after ligature of the renal pedicles. As a marker, intravenously injected14C-polyethylenglycol (14C-PEG) was used.

Regional Variation of Extracellular Space in the Hippocampus

Science, 1990
The factors responsible for the unusual susceptibility of the hippocampus to seizures and ischemic cell damage are not well understood. The CA1 pyramidal subfield of the hippocampus is particularly vulnerable to seizure activity and damage after ischemia.

EXTRACELLULAR SPACE IN THE CENTRAL NERVOUS SYSTEM

Archives of Neurology And Psychiatry, 1955
A KNOWLEDGE of the volume and composition of the extracellular space in brain substance is of considerable importance in any investigation dealing with electrolyte concentrations in nerve tissue and with mechanisms of fluid shifts in cerebral edema. Although fluid partitions have been thoroughly studied in the body as a whole, and in muscle tissue in ...

2001 interactions? An extracellular space odyssey

Current Opinion in Neurobiology, 1991
Abstract Recent investigation has revealed an incredible degree of complexity in the types and functions of extracellular matrix molecules and their cellular receptors in the nervous system.
