Sensitisation waves in a bidomain fire-diffuse-fire model of intracellular Ca²⁺ dynamics [PDF]

, 2009
We present a bidomain threshold model of intracellular calcium (Ca²⁺) dynamics in which, as suggested by recent experiments, the cytosolic threshold for Ca²⁺ liberation is modulated by the Ca²⁺ concentration in the releasing compartment.

Exploring intracellular space: function of the Min system in round-shaped Escherichia coli [PDF]

The EMBO Journal, 2002
The MinCDE proteins help to select cell division sites in normal cylindrical Escherichia coli by oscillating along the long axis, preventing unwanted polar divisions. To determine how the Min system might function in cells with multiple potential division planes, we investigated its role in a round-cell rodA mutant.

Tomographic Mapping of Brain Intracellular pH and Extracellular Water Space in Stroke Patients [PDF]

Journal of Cerebral Blood Flow & Metabolism, 1985
Functional images of regional intracellular pH (pHi) and of fractional volume of extracellular water (FVECW) were obtained in 10 patients with recent hemispheric infarction (between 10 and 19 days after onset of symptoms) using positron emission tomography (PET).

Typhoid toxin sorting and exocytic transport from Salmonella Typhi-infected cells

eLife, 2022
Typhoid toxin is an essential virulence factor for Salmonella Typhi, the cause of typhoid fever in humans. This toxin has an unusual biology in that it is produced by Salmonella Typhi only when located within host cells.

Evaluation and Validation of clinical 4.23 T sodium MRI in animals and human: Application of oblique multi-slice spin-echo pulse sequence [PDF]

, 2009
Objective: Application of high-field 4.23 T MRI clinical imager was demonstrated for sodium-magnetic resonance imaging (MRI) data acquisition. Primary hypothesis: Sodium [Na] in brain is MR visible. Secondary hypothesis was, if, application of multislice

Geometry based dynamic modeling of the neuron-electrode interface [PDF]

, 2000
A dynamic model of the neuron-electrode interface is presented which is based on the interface geometry and the electrical properties of the neuronal membrane. The model is used to compute the potential at the electrode and the local membrane potentials.

Determination of extracellular space and intracellular electrolytes in rat liver in vivo* [PDF]

The Journal of Physiology, 1971
1. Uptake of a number of isotopically labelled extracellular tracers by rat liver in vivo was studied.2. A residual intravascular space of 3·0–3·5% following exsanguination was measured by use of [51Cr]red cells. This space was significantly greater than that of skeletal muscle and was also greater in nephrectomized as compared to intact rats.3.

Tandem Protein Kinases Emerge as New Regulators of Plant Immunity

Molecular Plant-Microbe Interactions, 2021
Plant–pathogen interactions result in disease development in a susceptible host. Plants actively resist pathogens via a complex immune system comprising both surface-localized receptors that sense the extracellular space as well as intracellular ...

Evidence that both fast and slow water ADC components arise from intracellular space [PDF]

Magnetic Resonance in Medicine, 2002
AbstractEvaluation of water diffusion in the brain has revealed both fast‐ and slow‐diffusing water populations. It has been suggested that these populations represent extra‐ and intracellular water, respectively. We have identified and characterized both populations in the intracellular space of the Xenopus oocyte. We have also determined their T1 and
