On the basis of the experimental results and theoretical calculations, the remarkable properties of the catalysts can be attributed to the doping of carbon atoms into oxygen vacancies (OVs) and the formation of Ti-C bonds in C-TixOy. This binding motive is found to be energetically more favorable for N-2 activation compared to the non-substituted OVs in TiO2.

This association was especially pronounced when prenatal maternal depressed mood was present during the first trimester of pregnancy and when maternal mood was depressed pre- as well as postnatally.

In an epidemiological cohort study from birth to young adulthood, childhood ADHD diagnoses were assessed at the ages of 4.5, 8, and 11 years based on parent ratings. Sex-specific development of ADHD symptoms was analyzed from the age of 15 to 25 years via self-reported ADHD symptoms in participants with (n = 47) and without childhood ADHD (n = 289) using a random coefficient regression model. The congruence between parent reports and adolescents' self-ratings was examined, and the role of childhood ADHD diagnosis, childhood OCC/CD, and childhood internalizing disorder as possible sex-specific predictors of self-reported ADHD symptoms at age 25 years was investigated. With regard to self-reported ADHD symptoms, females with a childhood ADHD diagnosis reported significantly more ADHD symptoms compared to females without childhood ADHD and males with and without ADHD throughout adolescence and young adulthood. In contrast, males with childhood ADHD did not differ from control males either at age 15 or at age 25 years. Only in females did a childhood diagnosis of an externalizing disorder (ADHD and CD/ODD) predict self-reported ADHD symptoms by age 25 years.

Under favourable environmental conditions, competitive understorey species may develop high abundances and influence important ecosystem processes such as tree regeneration. Thus, understanding and predicting the response of competitive understorey species as a function of changing environmental conditions is important for forest managers. In the absence of sufficient temporal data to quantify actual vegetation changes, space-for-time (SFT) substitution is often used, i.e. studies that use environmental gradients across space to infer vegetation responses to environmental change over time. Here we assess the validity of such SFT approaches and analysed 36 resurvey studies from ancient forests with low levels of recent disturbances across temperate Europe to assess how six competitive understorey plant species respond to gradients of overstorey cover, soil conditions, atmospheric N deposition and climatic conditions over space and time. The combination of historical and contemporary surveys allows (i) to test if observed contemporary patterns across space are consistent at the time of the historical survey, and, crucially, (ii) to assess whether changes in abundance over time given recorded environmental change match expectations from patterns recorded along environmental gradients in space. We found consistent spatial relationships at the two periods: local variation in soil variables and overstorey cover were the best predictors of individual species' cover while interregional variation in coarse-scale variables, i.e. N deposition and climate, was less important. However, we found that our SFT approach could not accurately explain the large variation in abundance changes over time.

Whether temporal responses of community properties to current environmental changes are altered by such legacies is, however, unknown. We expect global environmental changes to interact with land-use legacies given different community trajectories initiated by prior management, and subsequent responses to altered resources and conditions. We tested this expectation for species richness and functional traits using 1814 survey-resurvey plot pairs of understorey communities from 40 European temperate forest datasets, syntheses of management transitions since the year 1800, and a trait database. We also examined how plant community indicators of resources and conditions changed in response to management legacies and environmental change. Community trajectories were clearly influenced by interactions between management legacies from over 200 years ago and environmental change. Importantly, higher rates of nitrogen deposition led to increased species richness and plant height in forests managed less intensively in 1800 (i.e., high forests), and to decreases in forests with a more intensive historical management in 1800 (i.e., coppiced forests). There was evidence that these declines in community variables in formerly coppiced forests were ameliorated by increased rates of temperature change between surveys. Responses were generally apparent regardless of sites' contemporary management classifications, although sometimes the management transition itself, rather than historic or contemporary management types, better explained understorey responses. Main effects of environmental change were rare, although higher rates of precipitation change increased plant height, accompanied by increases in fertility indicator values. Analysis of indicator values suggested the importance of directly characterising resources and conditions to better understand legacy and environmental change effects. Accounting for legacies of past disturbance can reconcile contradictory literature results and appears crucial to anticipating future responses to global environmental change.}, language = {en} } @article{PitzerEsserSchmidtetal.2017, author = {Pitzer, Martina and Esser, G{\"u}nter and Schmidt, Martin H. and Hohm, Erika and Banaschewski, Tobias and Laucht, Manfred}, title = {Child regulative temperament as a mediator of parenting in the development of depressive symptoms}, series = {Journal of neural transmission}, volume = {124}, journal = {Journal of neural transmission}, publisher = {Springer}, address = {Wien}, issn = {0300-9564}, doi = {10.1007/s00702-017-1682-2}, pages = {631 -- 641}, year = {2017}, abstract = {Child temperament as well as parenting behaviors have been linked to adolescent depression.

On the other hand, parenting may shape the child's temperament and vice versa in a transactional process.

Hierarchical linear regression analysis was used to investigate the prediction of depressive symptoms at age 11, measured by the Child Depression Inventory, including interaction terms between the temperament variable and parenting. We additionally tested whether parenting was mediated by child temperament. As previously reported, both self-control and parenting were longitudinally associated with preadolescent depressive symptoms. There were no interactive effects between temperament and parenting. However, the effects of parenting were partly mediated by self-control. Our data do not support a differential susceptibility of temperamental variants in the development of preadolescent depression.

This result suggests an effect of 5-HTTLPR on externalizing behavior in the presence of DRD4 7r but no effect in its absence.}, language = {en} } @article{SchmidBlomeyerBeckeretal.2009, author = {Schmid, Brigitte and Blomeyer, Dorothea and Becker, Katja and Treutlein, Jens and Zimmermann, Ulrich S. and Buchmann, Arlette F. and Schmidt, Martin H. and Esser, G{\"u}nter and Banaschewski, Tobias and Rietschel, Marcella and Laucht, Manfred}, title = {The interaction between the dopamine transporter gene and age at onset in relation to tobacco and alcohol use among 19-year-olds}, issn = {1355-6215}, doi = {10.1111/j.1369-1600.2009.00171.x}, year = {2009}, abstract = {Recent evidence suggests that heterogeneity in the age at onset could explain the inconsistent findings of association studies relating the dopamine transporter (DAT1) gene with alcohol and nicotine consumption. The aim of this study was to examine interactions between two DAT1 polymorphisms and different initiation ages with regard to alcohol and tobacco consumption levels and dependence. Two hundred and ninety-one young adults (135 males, 156 females) participating in the Mannheim Study of Children at Risk were genotyped for the 40-bp variable number of tandem repeats (VNTR) and rs27072 polymorphisms of DAT1. Age at initiation was assessed at age 15 and 19 years. Information about current alcohol and tobacco consumption was obtained at age 19 years using self-report measures and structured interviews. Results suggest that age at onset of intensive consumption moderated the association of the DAT1 gene with early adult substance use and dependence, revealing a DAT1 effect only among individuals homozygous for the 10r allele of the 40-bp VNTR who had started daily smoking or being intoxicated early in life. Equally, carriers of the T allele of the rs27072 polymorphism reporting an early age at first intoxication showed higher current alcohol consumption at age 19 years. In contrast, no interaction between rs27072 and the age at first cigarette with regard to later smoking was observed. These findings provide evidence that the DAT1 gene interacts with an early heavy or regular drug exposure of the maturing adolescent brain to predict substance (ab)use in young adulthood.

The aim of the current study was to prospectively ascertain the relationship between age at first cigarette and initial smoking experiences, and to examine the combined effects of these characteristics of adolescent smoking behavior on adult smoking. It was hypothesized that the association between earlier age at first cigarette and later development of nicotine dependence may, at least in part, be attributable to differences in experiencing pleasurable early smoking sensations. Data were drawn from the participants of the Mannheim Study of Children at Risk, an ongoing epidemiological cohort study from birth to adulthood. Structured interviews at age 15, 19 and 22 years were conducted to assess the age at first cigarette, early smoking experiences and current smoking behavior in 213 young adults. In addition, the participants completed the Fagerstrom Test for Nicotine Dependence. Adolescents who smoked their first cigarette at an earlier age reported more pleasurable sensations from the cigarette, and they were more likely to be regular smokers at age 22. The age at first cigarette also predicted the number of cigarettes smoked and dependence at age 22. Thus, both the age of first cigarette and the pleasure experienced from the cigarette independently predicted aspects of smoking at age 22.}, language = {en} } @article{JedrusikBodeStudenckaSmolkaetal.2013, author = {Jedrusik-Bode, Monika and Studencka, Maja and Smolka, Christian and Baumann, Tobias and Schmidt, Henning and Kampf, Jan and Paap, Franziska and Martin, Sophie and Tazi, Jamal and M{\"u}ller, Kristian M. and Kr{\"u}ger, Marcus and Braun, Thomas and Bober, Eva}, title = {The sirtuin SIRT6 regulates stress granule formation in C. elegans and mammals}, series = {Journal of cell science}, volume = {126}, journal = {Journal of cell science}, number = {22}, publisher = {Company of Biologists Limited}, address = {Cambridge}, issn = {0021-9533}, doi = {10.1242/jcs.130708}, pages = {5166 -- +}, year = {2013}, abstract = {SIRT6 is a NAD(+)-dependent deacetylase that modulates chromatin structure and safeguards genomic stability. Until now, SIRT6 has been assigned to the nucleus and only nuclear targets of SIRT6 are known. Here, we demonstrate that in response to stress, C. elegans SIR-2.4 and its mammalian orthologue SIRT6 localize to cytoplasmic stress granules, interact with various stress granule components and induce their assembly. Loss of SIRT6 or inhibition of its catalytic activity in mouse embryonic fibroblasts impairs stress granule formation and delays disassembly during recovery, whereas deficiency of SIR-2.4 diminishes maintenance of P granules and decreases survival of C. elegans under stress conditions. Our findings uncover a novel, evolutionary conserved function of SIRT6 in the maintenance of stress granules in response to stress.}, language = {en} } @article{BuchmannKopfWestphaletal.2010, author = {Buchmann, Arlette F. and Kopf, Daniel and Westphal, Sabine and Lederbogen, Florian and Banaschewski, Tobias and Esser, G{\"u}nter and Schmidt, Martin H. and Zimmermann, Ulrich S. and Laucht, Manfred and Deuschle, Michael}, title = {Impact of early parental child-rearing behavior on young adults' cardiometabolic risk profile : a prospective study}, issn = {0033-3174}, doi = {10.1097/Psy.0b013e3181c88343}, year = {2010}, abstract = {Objective: To examine prospectively whether early parental child-rearing behavior is a predictor of cardiometabolic outcome in young adulthood when other potential risk factors are controlled. Metabolic factors associated with increased risk for cardiovascular disease have been found to vary, depending on lifestyle as well as genetic predisposition. Moreover, there is evidence suggesting that environmental conditions, such as stress in pre- and postnatal life, may have a sustained impact on an individual's metabolic risk profile. Methods: Participants were drawn from a prospective, epidemiological, cohort study followed up from birth into young adulthood. Parent interviews and behavioral observations at the age of 3 months were conducted to assess child-rearing practices and mother-infant interaction in the home setting and in the laboratory. In 279 participants, anthropometric characteristics, low-density lipoprotein and high-density lipoprotein cholesterol, apolipoproteins, and triglycerides were recorded at age 19 years. In addition, structured interviews were administered to the young adults to assess indicators of current lifestyle and education. Results: Adverse early-life interaction experiences were significantly associated with lower levels of high- density lipoprotein cholesterol and apolipoprotein A1 in young adulthood. Current lifestyle variables and level of education did not account for this effect, although habitual smoking and alcohol consumption also contributed significantly to cardiometabolic outcomes. Conclusions: These findings suggest that early parental child-rearing behavior may predict health outcome in later life through its impact on metabolic parameters in adulthood.}, language = {en} } @article{BuchmannSchmidBlomeyeretal.2010, author = {Buchmann, Arlette F. and Schmid, Brigitte and Blomeyer, Dorothea and Zimmermann, Ulrich S. and Jennen-Steinmetz, Christine and Schmidt, Martin H. and Esser, G{\"u}nter and Banaschewski, Tobias and Mann, Karl F. and Laucht, Manfred}, title = {Drinking against unpleasant emotions : possible outcome of early onset of alcohol use?}, issn = {0145-6008}, doi = {10.1111/j.1530-0277.2010.01180.x}, year = {2010}, abstract = {Background: Recent animal and human studies indicate that the exposure to alcohol during early adolescence increases the risk for heavy alcohol use in response to stress. The purpose of this study was to examine whether this effect may be the consequence of a higher susceptibility to develop "drinking to cope" motives among early initiators. Methods: Data from 320 participants were collected as part of the Mannheim Study of Children at Risk, an ongoing epidemiological cohort study. Structured interviews at age 15 and 19 were used to assess age at first alcohol experience and drunkenness. The young adults completed questionnaires to obtain information about the occurrence of stressful life events during the past 4 years and current drinking habits. In addition, alcohol use under conditions of negative states was assessed with the Inventory of Drinking Situations. Results: The probability of young adults' alcohol use in situations characterized by unpleasant emotions was significantly increased the earlier they had initiated the use of alcohol, even when controlling for current drinking habits and stressful life events. Similar results were obtained for the age at first drunkenness. Conclusions: The findings strengthen the hypothesis that alcohol experiences during early adolescence facilitate drinking to regulate negative affect as an adverse coping strategy which may represent the starting point of a vicious circle comprising drinking to relieve stress and increased stress as a consequence of drinking.}, language = {en} }
