Exudates from fresh (stored at +4°C) and thawed pork and beef (frozen and stored below -20°C) was assayed by the rapid test kit API-ZYM(TM) to determine enzyme profiles. The test kit consists of 20 wells for different enzyme substrates. Of altogether 1040 results, only few reactions of the enzymes differed in their intensity between frozen and thawed pork(More)
This paper discusses the basic concept of the calibration of the SCIAMACHY instrument and remaining open issues. SCIAMACHY is a scanning Limb/Nadir spectrometer covering the wavelength range from 212 nm to 2386 nm. It was launched on-board ENVISAT in February 2002. In general the instrument performance is excellent: It per-5 forms as tested on ground and(More)
Schirmer-test, history of conjunctivitis, salivary gland scintigraphy and SSA/SSB (Ro/La) antibodies were evaluated in 24 patients with mesangial IgA glomerulonephritis (IgA-GN), 58 patients with non-IgA-GN and 100 healthy controls. A sicca syndrome (positive Schirmer-test) was found in 46% of patients with IgA-GN and 17% of non-IgA-GN and 8% of controls (p(More)

To test the reliability of a new cell transformation assay, a cloned fetal Syrian hamster lung epithelial cell line (M3E3/C3) was used. The target cells originating from the respiratory tract were treated in vitro over a concentration range of 0-10(-5) M/l with diepoxybutane, cultured during the expression period of 28 or 35 days and then transferred into(More)
OBJECTIVES To analyse the short-term kinetics of viral plasma RNA and CD4+ T cells numbers in patients with different initial CD4+ T-cell counts treated with different antiretroviral regimens. METHODS In 10 HIV-1 positive patients, in vivo kinetics of plasma HIV RNA and CD4+ T cells were studied during antiretroviral treatment. Lymphocyte subpopulation(More)
