• Activated by 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS) in a sustained intracellular acidification-dependence manner. (nih.gov)
  • DIDS (4,4-diisothiocyanatostilbenedisulphonic acid) induces apoptotic cell death in a hippocampal neuronal cell line and is not neuroprotective against ischemic stress. (nih.gov)
  • changes of intracellular Na + concentrations ([Na + ] i ) induced by readmission of different external K + concentrations ([K + ] o ) to tissues depleted of K + by 4‐h exposure to K + ‐free solution. (comprehensivephysiology.com)
  • Involved in pH regulation to eliminate acids generated by active metabolism or to counter adverse environmental conditions. (nih.gov)
  • Results The cumulative chloride secretory response of ΔI sc,carbachol , ΔI sc,cAMP/forskolin and ΔI sc,histamine was the best diagnostic ICM parameter (cut-off 34 μA/cm 2 between patients with known PS-CF and controls), differentiating patients with questionable CF into PS-CF (n=6) and 'CF unlikely' (n=55) groups.

  • Objectives To describe reference values and validate ICM for the diagnostic classification of questionable CF at all patient ages. (bmj.com)
  • CaCl 2 was added to reference cuvette to obtain 10 −5 M Ca 2+ . (comprehensivephysiology.com)
  • Follow-up information at ages 4 to 12 years was obtained on all 26 subjects. (nih.gov)
  • Conclusions This comprehensive investigation of CFTR function and genotype underlines the diagnostic value of ICM, especially for confirmation of CF in the absence of two disease-causing CFTR mutations, exclusion of CF despite intermediate sweat test and age groups unsuitable for nasal potential difference measurements.
