Psychophysical observations after anesthesia of the thumb raise the question whether the functional border between the thumb and the index is functionally distinct. We present a source localization study using equivalent current dipole modeling of somatosensory evoked potentials (SEPs) following mechanical air-puff stimulation of the first, second and third… (More)
For starter culture production, fluidized bed drying is an efficient and cost-effective alternative to the most frequently used freeze drying method. However, fluidized bed drying also poses damaging or lethal stress to bacteria. Therefore, investigation of impact of process variables and conditions on viability of starter cultures produced by fluidized bed… (More)
In this study, the feasibility of fluorescence lifetime imaging (FLIM) for measurement of RNA:DNA ratios in microorganisms was assessed. The fluorescence lifetime of a nucleic acid-specific probe (SYTO 13) was used to directly measure the RNA:DNA ratio inside living bacterial cells. In vitro, SYTO 13 showed shorter fluorescence lifetimes in DNA solutions… (More)
OBJECTIVES Outbreaks of sexually transmitted acute HCV infection have been described recently in several cities in the western world. The epidemic affects mainly MSM who are coinfected with HIV and is supposably linked to certain sexual risk practices. Here, we compared our findings with current knowledge and recommendations. METHODS HIV-positive patients… (More)

Cell disruption is necessary for the extraction of DNA, RNA or proteins from bacterial, plant and animal origin. Therefore a fast disruption method that is able to serve routine requirements and can deal with a great number of samples is advantageous. In this study we describe a fast DNA extraction method from seeds and amplification with PCR.
Objectives Before initiating an antiretroviral combination therapy which includes Maraviroc as one of its components, a coreceptor tropism test has to be performed. As Mara-viroc is only effective against HIV strains that are using CCR5 as coreceptor a thoroughly validated and reliable assay should be performed. In case of treatment change due to toxicity,… (More)
