Effects of K+-induced depolarization and purinergic receptor activation on elemental content in insulin-producing RINm5F-cells
- 1995
-
In: Cell Biology International. - : Wiley. - 1065-6995 .- 1095-8355. ; 19:1, s. 25-34

Journal article (peer-reviewed)abstract
- X-ray microanalysis was used to detect elemental changes in the insulin-producing tumor cell-lineRINm5F. To improve discrimination between mobile ions and ions bound to macromolecules a new approach was employed, consisting of multivariate statistical analysis of correlations between the concentrations of Na, Mg, P, S, CI, K, and Ca. RINm5F cells, cultured an Formvar-coated titanium grids, were stimulated with high K+ or ATP, that are both known to stimulate insulin release. The buffers used contained Ca2+ or one of the Ca2+-analogues Sr2+ and Ba2+, to represent Ca2+ uptake inresponse to stimulation. After stimulation the cells were shock-frozen and freeze-dried overnight. Incubation for 10-20 seconds in a Ca2+-containing buffer did not significantly affect elementalcomposition, whereas cellular Mg, P and K decreased in a Sr2+-containing buffer. Depolarization with high K+ concentration caused an increase in the cellular Na content, both in Ca2+- and Sr2+-containing buffers, but not in the buffer where Ca2+ had been replaced by Ba2+. X-ray microanalysis is useful for detection of elemental changes subsequent to stimulation of cultured cells. Moreover, multivariate statistical analysis strengthens the idea that stimulation of RINm5F cells causes redistribution of ions possibly due to changes in the state of binding of some elements to cellular proteins.

Proton-induced and electron-induced X-ray microanalysis of insulin-secreting cells

In: Scanning Microscopy Suppl.. ; 8, s. 325-333

Journal article (peer-reviewed)abstract
- Elemental redistribution induced by insulin secretion, was investigated by electron and proton probe X-ray microanalysis. In particular, ion fluxes following immediately upon stimulation were studied. As the sensitivity of the electron probe was insufficient, the proton microprobe was employed. In order to see whether the cell is asymmetric with respect to Ca2+ influx, the cells were stimulated in the presence of Sr2+ (as a Ca2+ analog). Insulin-secreting cells (RINm5F cells and isolated mouse beta-cells) were cultured on grids and shock-frozen at 2-30 seconds after stimulation. In a large number of cells, the major elements and and large fluxes were analyzed by the electron microprobe. In the proton microprobe, selected cells were analyzed and elemental maps were compared with electron micrographs of the same cells. The proton microprobe, but not the electron microprobe, could detect an influx of Sr in response to K+-stimulation for 2 seconds, in RINm5F cells. No polarization of Sr2+ uptake in RINm5F-cells could be detected, and the beta-cells did not respond to high K+ by uptake of Sr. Momentary stimulation of beta-cells also resulted in a significant increase in Na, detected by the electron probe. Spreading of the beta-cells on the substrate appears to influence the subcellular elemental distribution. Thus, the proton probe has potential to detect small changes in elements such as those occurring after short-time stimulation.

A determination of the centre-of-mass energy at LEP2 using radiative two-fermion events
- 2006
-

Journal article (peer-reviewed)abstract
- Using e(+)e(-) -> mu(+)mu(-)(gamma) and e(+)e(-) -> q (q) over bar(gamma) events radiative to the Z pole, DELPHI has determined the centre-of-mass energy, root s, using energy and momentum constraint methods. The results are expressed as deviations from the nominal LEP centre-of-mass energy, measured using other techniques. The results are found to be compatible with the LEP Energy Working Group estimates for a combination of the 1997 to 2000 data sets.
