- Radiative lifetime measurements were performed by time-resolved laser-induced fluorescence (LIF) technique for eight even-parity levels of the astrophysically important ion Er+ over the energy range from 33753 to 55317 cm(-1). Free erbium ions were generated by a laser-induced plasma. A narrow bandwidth UV laser pulse (1 ns) was employed to populate selectively the short-lived upper levels, and the lifetime value were evaluated from the time-resolved fluorescence signals. The lifetimes reported fall in the range of 3-35ns with the experimental accuracy 5-8%.

- The immobilization of cytochrome c (Cyt-c) in ordered mesoporous niobium oxide thin films is investigated for the first time. The direct electrochemical behavior of Cyt-c assembled onto the. inorganic matrix (see Figure) and the electrocatalytic properties of this assembly are studied. The results open a new doorway for the application of niobium oxides as bioanalytical devices.

- Surface-enhanced Raman scattering of single-walled carbon nanotubes (SWNTs) on silver films deposited on various substrates, including sapphire, quartz and glass, has been studied systematically. The characteristic features of G-band and D-band have been analyzed and compared with arc discharged and laser ablation samples. D-band is much more sensitive than G-band. The position and the intensity of the G-band in SERS spectra depend on substrates. The peak shift and absolute intensity of G-band on sapphire is obviously larger than that on glass. The contribution of high frequency vibrations to the D-band is also deendent on substrates. Compared to the SWNTs samples with a high semiconducting tube concentration, the sample with high metallic tube concentration has a stronger interaction with silver films.

Specific tissue expression and cellular localization of human apolipoprotein M as determined by in situ hybridization
- 2003

Tidskriftsartikel (refereegranskat)abstract
- Apolipoprotein M (apoM) is a recently discovered human apolipoprotein predominantly present in high-density lipoprotein (HDL), and in minor proportion in triglyceride-rich lipoprotein (TGRLP) and low-density lipoprotein (LDL). The gene coding for apoM has been detected in all mammal genomes. The function of apoM is unknown yet. In the present study, we demonstrated that apoM is exclusively expressed in a strong manner in adult liver and kidney, and is expressed weakly in fetal liver and kidney as detected with human multiple tissue expression array. Both immumohistochemical staining and apoM mRNA in situ hybridization demonstrated that apoM was exclusively expressed in hepatocytes in human liver and in tubular epithelial cells in human kidney. The present study helps to elucidate the pathophysiological functions of apoM in vivo.
