Intracellular alkalinization was produced, where indicated, by 1) increasing the medium pH to 8.3, 2) adding 5 mmol/l ammonium chloride to the medium, or 3) substituting the [Cl.sup.-] in the medium with [gluconate.sup.-].
In rat islets, glucose-induced increase in intracellular pH was reversed by the absence of HC[O.sub.3.sup.-] (11).
The importance of intracellular pH in the induction of priming by glucose is not surprising, considering all of the documented effects of intracellular pH on nutrient-induced acute insulin release.

Both the intracellular oxidation and calcium rise induced by internalized bleomycin are inhibited by pretreatment of cells with varying concentrations of taurine (25, 125, and 187.5 µM).
The ratio of fluorescence excited at 340 nm to that at 380 nm was used as an indicator of the intracellular calcium rise in response to stimulation by 4 µg/ml bleomycin in the control and taurine-treated cells.
The bleomycin-mediated intracellular oxidation is Fe -dependent and occurs in the absence of extracellular Fe This suggests that the internalization of bleomycin is required for the observed oxidation.

This elevation of intracellular calcium was directly related to the absolute age of the neurons, not to the length of time in culture.
In another paradigm, measurements of intracellular calcium were determined in NGF-dependent neurons "committed to die" after NGF withdrawal.
No elevation in intracellular calcium was found in these dying neurons, but rather, a small decrease was observed prior to the disintegration of the neurons.

 Journal of Bone and Joint Surgery: Intracellular Staphylococcus aureus: A mechanism for the indolence of osteomyelitis
In previous studies, the membrane of the osteoblast was lysed with detergent and intracellular pathogens were removed.
Our aim therefore was to document the fate of the intracellular bacteria after a more natural cause of death of osteoblasts, creating a process which reflected the clinical situation more closely.
After either detergent lysis or death of osteoblasts via trypsinisation, previously intracellular bacteria were harvested and grown overnight to achieve equivalent numbers for infection and then used to infect other sterile osteoblast cultures.

 Lawrence S. B. Goldstein
Summary: Lawrence Goldstein is interested in understanding the molecular mechanisms of intracellular movement in neurons and the role of transport failure in neurodegenerative diseases.
Because of their large size and highly extended morphology, neurons incur a substantial burden of intracellular movement and transport.
Previous work revealed that most intracellular movement in neurons is generated by motor proteins such as kinesin, dynein, or myosin.

To determine the distribution of cerebral glucose and lactate between the intracellular and the extracellular space of the rat brain in vivo, the diffusion characteristic of glucose and lactate was compared with that of metabolites known to be mainly intracellular (N-acetylaspartate, choline, creatine, glutamate, myo-inositol, and taurine) using a pulsed-field-gradient
At small diffusion weighting, the ADC of glucose and lactate was increased, which was explained by a decreased relative contribution of intracellular glucose to the total signal.
The findings were direct in vivo evidence that the largest concentration gradient of glucose is at the blood-brain barrier and that glucose is evenly distributed in the brain in vivo between the intracellular and extracellular space.

 Intracellular Cytokine Staining
A modification of the basic immunofluorescence staining and flow cytometric analysis protocol can be used for the simultaneous analysis of surface molecules and intracellular cytokines at single-cell level.
In this protocol, cells are first activated in vitro, stained for surface antigens, as in the regular staining protocol, then fixed and permeabilized to allow for anti-cytokine antibodies to stain intracellularly.
In contrast to detection of secreted cytokines by ELISA, for detection of intracellular cytokines, it is necessary to block secretion of cytokines with reagents such as Monensin or Brefeldin A during the last few hours of the stimulation.

 Cell (biology) - Wikipedia, the free encyclopedia
Prokaryotes are distinguished from eukaryotes on the basis of nuclear organization, specifically their lack of a nuclear membrane.
Prokaryotes also lack most of the intracellular organelles and structures that are characteristic of eukaryotic cells (an important exception is the ribosomes, which are present in both prokaryotic and eukaryotic cells).
Most of the functions of organelles, such as mitochondria, chloroplasts, and the Golgi apparatus, are taken over by the prokaryotic plasma membrane.
