However, the analysis of fatty aldehydes, which are important components of cell metabolism, remains challenging. Usually, chemical derivatization prior to MS detection is required to enhance ionization efficiency. In this regard, the coupling of fatty aldehydes to hydrazines like 2,4-dinitrophenylhydrazine (DNPH) is a common approach. Additionally, hydrazones readily react with fatty aldehydes to form stable derivatives, which can be easily separated using high-performance liquid chromatography (HPLC) and subsequently detected by MS. Here, we exemplarily present the quantification of the long-chain fatty aldehyde (2E)-hexadecenal, a break-down product of the bioactive lipid sphingosine 1-phosphate (S1P), after derivatization with 2-diphenylacetyl-1,3-indandione-1-hydrazone (DAIH) via isotope-dilution HPLC-electrospray ionization-quadrupole/time-of-flight (ESI-QTOF) MS. Moreover, we show that the addition of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDC hydrochloride) as a coupling agent allows for simultaneous determination of fatty aldehydes and fatty acids as DAIH derivatives.

Sphingolipid levels are dynamically maintained by the action of sphingolipid enzymes of which sphingosine kinases, S1P phosphatases (SGPP-1/2) and S1P lyase (SGPL-1), are pivotal in the balance of S1P and sphingosine levels. In this study, we present that SGPP-1 and SGPL-1 are regulated in inflammatory dendritic cells and contribute to S1P fate. TLR-dependent activation caused SGPL-1 protein downregulation with subsequent decrease of enzymatic activity by two-thirds. In parallel, confocal fluorescence microscopy revealed that endogenous SGPP-1 was expressed in nuclei of naive dendritic cells and was translocated into the cytoplasmatic compartment upon inflammatory stimulation resulting in dephosphorylation of S1P. Mass spectrometric determination showed that a part of the resulting sphingosine was released from the cell, increasing extracellular levels. Another route of diminishing intracellular S1P was possibly taken by its export via ATP-binding cassette transporter C1 which was upregulated in array analysis, while the S1P transporter, spinster homolog 2, was not relevant in dendritic cells. These investigations newly describe the sequential expression and localization of the endogenous S1P regulators SGPP-1 and SGPL-1 and highlight their contribution to the sphingolipid rheostat in inflammation.}, language = {en} } @article{YueAlterHowardetal.2017, author = {Yue, Jinxing and Alter, Kai-Uwe and Howard, David and Bastiaanse, Roelien}, title = {Early access to lexical-level phonological representations of Mandarin word-forms}, series = {Language, cognition and neuroscience}, volume = {32}, journal = {Language, cognition and neuroscience}, number = {9}, publisher = {Routledge, Taylor \& Francis Group}, address = {Abingdon}, issn = {2327-3798}, doi = {10.1080/23273798.2017.1290261}, pages = {1148 -- 1163}, year = {2017}, abstract = {An auditory habituation design was used to investigate whether lexical-level phonological representations in the brain can be rapidly accessed after the onset of a spoken word.

In this paper; the influence of pH on the transition between random coil and beta-sheet conformation of VK20; including the transition kinetics, were investigated. At pH values of 9 and higher, the kinetics beta-sheet formation increased tor VK(2 0, compared to MAXI. The self-assembly into beta-sheets recognized by the formation of a physically crosslinked gel was furthermore indicated by a significant increase of G. An increase in pH (from 9 to 9.5) led to a faster gelation of the peptide VK20. Simultaneously, G was increased from 460 +/- 70 Pa (at pH 9) to 1520 +/- 180 Pa (at pH 9.5). At the nanoscale, the gel showed a highly interconnected fibrillar/network structure with uniform fibril widths of approximately 3.4 +/- 0.5 nm (N=30). The recovery of the peptide conformation back to random coil resulted in the dissolution of the gel; whereby the kinetics of the recovery depended on the pH.

Objective: To isolate antiplasmodial compounds from these plant species which could be used as marker compounds in the standardization of their extracts as a phytomedicine for malaria. Methods: Constituents were isolated through activity-guided fractionation of the MeOH/CHCl3 (1:1) extracts and in vitro inhibition of Plasmodium falciparum. Cytotoxicity was evaluated using Vero cells and the compounds were elucidated on the basis of NMR spectroscopy. Results: Fractionation of the extracts resulted in the isolation of ten known compounds. Compound 1 showed promising antiplasmodial activity with IC50, 3.63 and 3.95 ng/ml against chloroquine sensitive (D6) and resistant (W2) P. falciparum, respectively and moderate cytotoxicity (CC50, 37.5 ng/ml) against Vero E6 cells.

Prediction errors (PEs) are thought to mediate flexible decision-making by updating the reward values associated with available actions. In this study, we explored whether the neurobiological correlates of PEs are altered in alcohol dependence. Behavioral, and functional magnetic resonance imaging (fMRI) data were simultaneously acquired from 34 abstinent alcohol-dependent patients (ADP) and 26 healthy controls (HC) during a probabilistic reward-guided decision-making task with dynamically changing reinforcement contingencies. A hierarchical Bayesian inference method was used to fit and compare learning models with different assumptions about the amount of task-related information subjects may have inferred during the experiment. Here, we observed that the best-fitting model was a modified Rescorla-Wagner type model, the "double-update" model, which assumes that subjects infer the knowledge that reward contingencies are anti-correlated, and integrate both actual and hypothetical outcomes into their decisions. Moreover, comparison of the best-fitting model's parameters showed that ADP were less sensitive to punishments compared to HC. Hence, decisions of ADP after punishments were loosely coupled with the expected reward values assigned to them. A correlation analysis between the model-generated PEs and the fMRI data revealed a reduced association between these PEs and the BOLD activity in the dorsolateral prefrontal cortex (DLPFC) of ADP. A hemispheric asymmetry was observed in the DLPFC when positive and negative PE signals were analyzed separately. The right DLPFC activity in ADP showed a reduced correlation with positive PEs. On the other hand, ADP, particularly the patients with high dependence severity, recruited the left DLPFC to a lesser extent than HC for processing negative PE signals. These results suggest that the DLPFC, which has been linked to adaptive control of action selection, may play an important role in cognitive inflexibility observed in alcohol dependence when reinforcement contingencies change. Particularly, the left DLPFC may contribute to this impaired behavioral adaptation, possibly by impeding the extinction of the actions that no longer lead to a reward.}, language = {en} } @article{KaufmannMaiwaldSchindleretal.2017, author = {Kaufmann, Yvonne Marie and Maiwald, Lisa Marie and Schindler, Svenja and Weck, Florian}, title = {Wie wirkt sich mehrmaliges Kompetenz-Feedback auf psychotherapeutische Behandlungen aus?}, series = {Zeitschrift f{\"u}r klinische Psychologie und Psychotherapie : Forschung und Praxis}, volume = {46}, journal = {Zeitschrift f{\"u}r klinische Psychologie und Psychotherapie : Forschung und Praxis}, number = {2}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {1616-3443}, doi = {10.1026/1616-3443/a000412}, pages = {96 -- 106}, year = {2017}, abstract = {Theoretischer Hintergrund: Einfl{\"u}sse von therapeutenorientiertem Kompetenz-Feedback in der Psychotherapieausbildung wurden bislang wenig untersucht.

The perception of being able to cope with work is a basic requirement for work ability. This randomized controlled trial investigates whether a cognitive behavioural, work-anxiety-coping group (WAG) intervention leads to better work-coping perception than an unspecific recreational group (RG). Heterogeneous people in medical rehabilitation, who were due to return to work, were interviewed concerning their work-anxieties, and either randomly assigned to a WAG (n=85) or a RG (n=95). The participants (with an average of 50years old [range 23-64]; 51\% women; 70\% workers or employees, 25\% academics, 5\% unskilled) followed the group intervention for four or six sessions. The perceived work-coping was assessed by self-rating (Inventory for Job-Coping and Return Intention JoCoRi) after each group session. Although participants had a slight temporary decrease in work-coping after group session two (from M-1=2.47 to M-2=2.28, d(Cohen)=-.22), the WAG led to the improvement of perceived work-coping over the intervention course (from M-1=2.47 to M-6=2.65, d(Cohen)=.18). In contrast, participants from the RG reported lower work-coping after six group sessions (from M-1=2.26 to M-6=2.02, d(Cohen)=-.18). It is considered that people with work-anxieties need training in work-coping. By focusing on recreation only, this may lead to deterioration of work-coping. Indeed, intervention designers should be aware of temporary deterioration (side effects) when confronting participants with work-coping.}, language = {en} } @article{Daviter2017, author = {Daviter, Falk}, title = {Coping, taming or solving}, series = {Policy studies}, volume = {38}, journal = {Policy studies}, number = {6}, publisher = {Routledge, Taylor \& Francis Group}, address = {Abingdon}, issn = {0144-2872}, doi = {10.1080/01442872.2017.1384543}, pages = {571 -- 588}, year = {2017}, abstract = {One of the truisms of policy analysis is that policy problems are rarely solved. As an ever-increasing number of policy issues are identified as an inherently ill-structured and intractable type of wicked problem, the question of what policy analysis sets out to accomplish has emerged as more central than ever. If solving wicked problems is beyond reach, research on wicked problems needs to provide a clearer understanding of the alternatives. The article identifies and explicates three distinguishable strategies of problem governance: coping, taming and solving. It shows that their intellectual premises and practical implications clearly contrast in core respects. The article argues that none of the identified strategies of problem governance is invariably more suitable for dealing with wicked problems. Rather than advocate for some universally applicable approach to the governance of wicked problems, the article asks under what conditions different ways of governing wicked problems are analytically reasonable and normatively justified. It concludes that a more systematic assessment of alternative approaches of problem governance requires a reorientation of the debate away from the conception of wicked problems as a singular type toward the more focused analysis of different dimensions of problem wickedness.}, language = {en} } @misc{KuehnSchoene2017, author = {K{\"u}hn, Michael and Sch{\"o}ne, Tim}, title = {Multivariate regression model from water level and production rate time series for the geothermal reservoir Waiwera (New Zealand)}, series = {Energy procedia}, volume = {125}, journal = {Energy procedia}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1876-6102}, doi = {10.1016/j.egypro.2017.08.196}, pages = {571 -- 579}, year = {2017}, abstract = {Water management tools are necessary to guarantee the preservation of natural resources while ensuring optimum utilization. Linear regression models are a simple and quick solution for creating prognostic capabilities. Multivariate models show higher precision than univariate models. In the case of Waiwera, implementation of individual production rates is more accurate than applying just the total production rate. A maximum of approximately 1,075 m3/day can be pumped to ensure a water level of at least 0.5 m a.s.l. in the monitoring well.

Further, we demonstrate that considering specific rock microstructures is of paramount importance, since calculated elastic properties may deviate by up to 230 \% for the same mineral composition. Moreover, agreement between simulated and experimentally determined Young's moduli is significantly improved, when detailed spatial information are employed.}, language = {en} }
