    Notizen: Abstract Therapists need a novel approach with externalizing, hard-to-reach patients, who blame others for their problems and feel empty. In this article a technique is presented for treatment of such clients. It specifically involves helping such individuals to experience their affect initially in therapy. This method assists clients in becoming aware of their visceral sensations, which are the manifestations of emotions. Learning to monitor their physical reactions is a lengthy process with externalizers, but once they master doing this and reach a level of awareness of them, they start to experience their feelings and they begin having insights. This eventually leads to self-observation and understanding. A case example using this method is presented in the article. It illustrates how a specific patient moved from feeling empty and blaming others for all his problems to first recognizing his sensations, then to become aware of his feelings and finally starting to reach an understanding of himself.

    Lipofuscin accumulation in tissues of Arctica islandica indicates faster ageing in populations from brackish environments (2017)

    Beschreibung: Environmental factors can affect the rate of ageing and shape the lifespan in marine ectotherms. The mechanisms and the degree of - environmental influence on aging can best be studied in species with wide ranging biogeographic distribution. One of the biomarkers of physiological ageing is the fluorescent age pigment lipofuscin, which accumulates over lifetime in tissues of bivalves. We compared lipofuscin accumulation rate in muscles and respiratory tissues of the extremely long lived bivalve Arctica islandica from five geographically distinct populations (Northern Norway, White Sea, Kiel Bay, German Bight and Iceland). Maximum investigated chronological age across different populations in the present study differed from 40 years in Kiel Bay to 192 years at Iceland. An inverse association between lipofuscin deposition rate and recorded maximum age was observed through inter-population comparisons. In most cases lipofuscin accumulated exponentially over age in a tissue specific manner. The age specific lipofuscin content was significantly higher in respiratory than muscles tissues in all populations. Cellular lipofuscin granule area can be used as indicator of aging across A. islandica populations with the variance in granule accumulation depending on the annual variations of salinity in different marine regions, but not on the habitat specific thermal envelope.

    A shell regeneration assay to identify biomineralization candidate genes in mytilid mussels (2016)

    Beschreibung: Biomineralization processes in bivalve molluscs are still poorly understood. Here we provide an analysis of specifically expressed sequences from a mantle transcriptome of the blue mussel, Mytilus edulis. We then developed a novel, integrative shell injury assay to test, whether biomineralization candidate genes highly expressed in marginal and pallial mantle could be induced in central mantle tissue underlying the damaged shell areas. This experimental approach makes it possible to identify gene products that control the chemical micro-environment during calcification as well as organic matrix components. This is unlike existing methodological approaches that work retroactively to characterize calcification relevant molecules and are just able to examine organic matrix components that are present in completed shells. In our assay an orthogonal array of nine 1 mm holes was drilled into the left valve, and mussels were suspended in net cages for 20, 29 and 36 days to regenerate. Structural observations using stereo-microscopy, SEM and Raman spectroscopy revealed organic sheet synthesis (day 20) as the first step of shell-repair followed by the deposition of calcite crystals (days 20 and 29) and aragonite tablets (day 36). The regeneration period was characterized by time-dependent shifts in gene expression in left central mantle tissue underlying the injured shell, (i) increased expression of two tyrosinase isoforms (TYR3: 29-fold and TYR6: 5-fold) at day 20 with a decline thereafter, (ii) an increase in expression of a gene encoding a nacrein-like protein (max. 100-fold) on day 29. The expression of an acidic Asp-Ser-rich protein was enhanced during the entire regeneration process. This proof-of-principle study demonstrates that genes that are specifically expressed in pallial and marginal mantle tissue can be induced (4 out of 10 genes) in central mantle following experimental injury of the overlying shell. Our findings suggest that regeneration assays can be used systematically to better characterize gene products that are essential for distinct phases of the shell formation process, particularly those that are not incorporated into the organic shell matrix.

    Trace element analysis of climate archives by laser ablation ICP-MS (2008)

    Beschreibung: The analysis of the inorganic composition of climatic archives provides proxies for climate reconstruction. For many applications commercially available inductively coupled plasma quadrupole mass spectrometry (ICP-Q-MS) systems are used for investigations. In this talk I will present different application possibilities of the laser ablation (LA)-ICP-Q-MS analysis of different sample matrices.Polar ice cores:Ice from polar regions is an archive of climate. The analysis of element signatures in ice cores yields information about the strength of sources and transport mechanisms for aerosols in the paleoatmosphere as well as about the paleovolcanism. An ice core section from the Holocene, drilled in the Atlantic sector of Antarctica, was analysed by LA-ICP-Q-MS with a spatial resolution of about 4 mm. The analysis of sea salt tracers, mineral dust tracers and tracers for other natural or anthropogenic sources revealed in general enhanced element concentrations during winter months. The ice core included a tephra horizon which source could be identified by the element composition.Bivalves:During the past 10 years, the enhanced input of sediments due to accelerated glaciermelting is observed in Potter Cove at the Antarctic Peninsula. The analysis of the Antarctic soft shell clam Laternula elliptica (Potter Cove, Antarctic Peninsula) by LA-ICP-Q-MS addressed whether the increased sediment input is reflected in the distribution of Fe, and other elements (Al, Mn, Cu, Pb and U) in the ultimate growth bands, which are formed in bivalve umbos. In contrast to our hypothesis, we proved that the accretion of our investigated elements into the umbo matrix is largely a function of animal ecophysiology and life history rather than of climate change.Frozen lake sediment cores:A frozen lake sediment core from Sacrower See (Potsdam Germany), investigated by LA-ICP-Q-MS, showed annual lamination until a depth of 42.7 cm. Our study targeted to settle the question whether the lamination results in varying elemental signature that corresponds to summer and winter layers, with respectively high and low biological activity. The enrichment or depletion of a certain element in a sample relative to the average composition of the Earths crust is expressed as the enrichment factor (EF). From the increased EF of Ca and Sr in the summer layers, we conclude an increased biological activity.
