Since its discovery in the 1920’s the relaxin peptide hormone family has not only grown in number to now seven members （relaxin-1, relaxin-2, relaxin-3, insulin-like peptide （INSL） 3, INSL4, INSL5 and INSL6）, but...Since its discovery in the 1920’s the relaxin peptide hormone family has not only grown in number to now seven members （relaxin-1, relaxin-2, relaxin-3, insulin-like peptide （INSL） 3, INSL4, INSL5 and INSL6）, but ever more effects, suchs as vasodilatory, angiogenic, anti-apoptopic, anti-fibriotic and anti-inflammatory, have been linked to them. While relaxin-2 has mainly been investigated in the context of cardiac protection, most comprehensively in the RELAX-AHF and RELAX AHF2 studies, a small number of studies have furthermore assessed the potential neuroprotective effects of especially relaxin-2 and other members of the relaxin family. In this short review we summarise and discuss recent efforts to utilize relaxin hormones for neuroprotection and point out potential future fields of research and translational applications. While many questions still need to be answered, the promising results of the available studies definitely warrant future well-designed studies on neuroprotection by relaxin peptides.展开更多

The combination of a new CNC module with a white light aerosol spectrometer and a passive collector makes possible accurate time-resolved determination of particle number within the overall size range of 10 nm to 40 μm and at concentrations up to 10^5 particles/cm^3. With the aerosol spectrometer a high time-resolved particle size determination is also possible in the size range of 0.3-40 μm up to the same high number concentrations of 10^5 particles/cm^3.展开更多
