Sensitization of adenylyl cyclase (AC) by increased expression of large isoforms of the stimulatory G-protein Galpha(s) has been suggested as a mechanism that governs uterine quiescence during pregnancy. We quantified several components of the AC pathway in pregnant (P, n=21) and nonpregnant human myometria (NP, n=10). AC activity was approximately… (More)
In the framework of the CARAT collaboration, which executes work package 15 of the EU FP7 " HadronPhys-ics2 " project, the diamond group at the University of Augsburg is responsible for the development and growth of heteroepitaxial diamond films, which shall be used in particular for tracking and ToF measurements of heavy ions and minimum ionising particles.
We report Stimulated Emission Depletion (STED) imaging of green fluorescent nanodiamonds containing Nitrogen-Vacancy-Nitrogen (NVN) centers with a resolution of 70 nm using a commercial microscope. Nanodiamonds have been demonstrated to have the potential to be excellent cellular biomarkers thanks to their low toxicity and nonbleaching fluorescence, and are… (More)
In the last year, we continued with the development of large-area diamond sensors grown at the University of Augsburg by chemical vapour deposition (CVD) on wafer scale Ir/YSZ/Si(001) substrates. Early results of diamond-on-iridium (DoI) sensors  were indicating significant defect densities within the detector bulk, which led to reduced charge collection… (More)
Scanning probe microscopy (SPM) techniques have had a great impact on research fields of surface science and nanotechnology during the last decades. They are used to investigate surfaces with scanning ranges between several 100 m down to atomic resolution. Depending on experimental conditions, and the interaction forces between probe and sample, different… (More)
