In recent studies, the exercise-induced increases in cardiac biomarkers in endurance athletes as well as acute alterations in cardiac function and cardiovascular abnormalities have been reported. As elevations of the cardiac biomarkers troponin and BM) have been observed frequently for the vast majority of athletes after Marathon runs or strenuous exercise bouts followed by a decrease within a short period, a physiological reaction rather than a pathologicial cause is presumed. Also a transient decrease of cardiac function demonstrated by newer echocardiographic techniques (tissue Doppler or speckle tracking imaging, 3D echocardiography) after strenuous exercise often termed "cardiac fatigue" should not be considered necessarily as pathologic, as cardiac function also depends on hemodynamic load and heart rate. Furthermore, exercise-induced changes in cardiac function did not correlate with exercise-induced increases in cardiac biomarkers in most studies. The functional cardiac alterations can also be detected by magnetic resonance imaging (MRI) after Marathon runs. However, no signs of acute or chronic myocardial damage have been demonstrated in MRI studies in cardiovascular healthy athletes after running a Marathon, although especially in older athletes undetected cardiovascular diseases such as coronary artery disease or myocardial necrosis or fibrosis can be present. hi conclusion, according to recent studies. there seems to be a lack of evidence to support endurance exercise-induced cardiac damage in the healthy heart which is adapted tostrenous exercise by regular endurance training. Nevertheless, as running a Marathon results in a high cardiac load, a sufficient endurance training period as well as a preparticipation or regular medical screening to exclude relevant congenital or aquired cardiovascular diseases is recommended from a sports cardiology perspective to exclude relevant congenital or acquired cardiovascular diseases}, language = {de} } @article{KahlertBrand2011, author = {Kahlert, Daniela and Brand, Ralf}, title = {Comparing self-report and accelerometry data a contribution to the validation of the MoMo-Physical activity questionnaire for children and adolescents}, series = {Deutsche Zeitschrift f{\"u}r Sportmedizin : offizielles Organ der Deutschen Gesellschaft f{\"u}r Sportmedizin und Pr{\"a}vention (Deutscher Sport{\"a}rztebund) e.V.

The present study compares two different methods of assessing physical activity with the purpose of testing the validity of the MoMo-AFB self-report. First, we measured the physical activity status of 73 15 to 18-year-old pupils (32 boys and 41 girls) over seven days via objective accelerometry (ActiGraph GT1M), then the pupils completed the MoMo-AFB for the same (previous) period. Results show that using the MoMo-AFB leads to higher levels of self-reported physical activity than measuring it with accelerometers. Furthermore, only the MoMo-AFB subscale MVPA (moderate-to-vigorous physical activity), that uses two single items to decide whether the health-enhancing physical activity recommendation is reached or failed, corresponds statistically significantly with the accelerometry data. For all other subscales (e.g. school- or leisure time activity), we found no agreement. Further research, first of all on the measurement quality of the MoMo-AFB but also on the physical (in)activity status of children and adolescents, is needed.}, language = {de} } @article{Krueger2011, author = {Kr{\"u}ger, Hans-Peter}, title = {The body-body-difference of persons eccentric positionality and homo absconditus}, series = {Deutsche Zeitschrift f{\"u}r Philosophie : Zweimonatsschrift der internationalen philosophischen Forschung}, volume = {59}, journal = {Deutsche Zeitschrift f{\"u}r Philosophie : Zweimonatsschrift der internationalen philosophischen Forschung}, number = {4}, publisher = {De Gruyter}, address = {Berlin}, issn = {0012-1045}, pages = {577 -- 589}, year = {2011}, language = {de} } @article{DelahayeXieSchaeferetal.2011, author = {Delahaye, Emilie and Xie, Zailai and Sch{\"a}fer, Andreas and Douce, Laurent and Rogez, Guillaume and Rabu, Pierre and G{\"u}nter, Christina and Gutmann, Jochen S. and Taubert, Andreas}, title = {Intercalation synthesis of functional hybrid materials based on layered simple hydroxide hosts and ionic liquid guests - a pathway towards multifunctional ionogels without a silica matrix?}, series = {Dalton transactions : a journal of inorganic chemistry, including bioinorganic, organometallic, and solid-state chemistry}, volume = {40}, journal = {Dalton transactions : a journal of inorganic chemistry, including bioinorganic, organometallic, and solid-state chemistry}, number = {39}, publisher = {Royal Society of Chemistry}, address = {Cambridge}, issn = {1477-9226}, doi = {10.1039/c1dt10841g}, pages = {9977 -- 9988}, year = {2011}, abstract = {Functional hybrid materials on the basis of inorganic hosts and ionic liquids (ILs) as guests hold promise for a virtually unlimited number of applications. In particular, the interaction and the combination of properties of a defined inorganic matrix and a specific IL could lead to synergistic effects in property selection and tuning. Such hybrid materials, generally termed ionogels, are thus an emerging topic in hybrid materials research. The current article addresses some of the recent developments and focuses on the question why silica is currently the dominating matrix used for (inorganic) ionogel fabrication. In comparison to silica, matrix materials such as layered simple hydroxides, layered double hydroxides, clay-type substances, magnetic or catalytically active solids, and many other compounds could be much more interesting because they themselves may carry useful functionalities, which could also be exploited for multifunctional hybrid materials synthesis. The current article combines experimental results with some arguments as to how new, advanced functional hybrid materials can be generated and which obstacles will need to be overcome to successfully achieve the synthesis of a desired target material.}, language = {en} } @article{MarquardtXieTaubertetal.2011, author = {Marquardt, Dorothea and Xie, Zailai and Taubert, Andreas and Thomann, Ralf and Janiak, Christoph}, title = {Microwave synthesis and inherent stabilization of metal nanoparticles in 1-methyl-3-(3-carboxyethyl)-imidazolium tetrafluoroborate}, series = {Dalton transactions : a journal of inorganic chemistry, including bioinorganic, organometallic, and solid-state chemistry}, volume = {40}, journal = {Dalton transactions : a journal of inorganic chemistry, including bioinorganic, organometallic, and solid-state chemistry}, number = {33}, publisher = {Royal Society of Chemistry}, address = {Cambridge}, issn = {1477-9226}, doi = {10.1039/c1dt10795j}, pages = {8290 -- 8293}, year = {2011}, abstract = {The synthesis of Co-NPs and Mn-NPs by microwave-induced decomposition of the metal carbonyls Co-2(CO)(8) and Mn-2(CO)(10), respectively, yields smaller and better separated particles in the functionalized IL 1-methyl-3-(3-carboxyethyl)-imidazolium tetrafluoroborate [EmimCO(2)H][BF4] (1.6 +/- 0.3 nm and 4.3 +/- 1.0 nm, respectively) than in the non-functionalized IL 1-n-butyl-3-methylimidazolium tetrafluoroborate [Bmim][BF4].

Soil samples and plant material were analyzed to determine the effect of different vermicompost application rates on the physical and chemical properties. Results revealed that the physical and chemical properties of the soil improved with increasing application rates of vermicompost. In addition, soil treated with vermicompost showed significant increases in fresh-and dry-matter yields of the grass, as well as enhanced uptake of nutrients by the grass.

Every day thousands of events are happening and millions of pictures are taken. By choosing photographs for newspapers and magazines, photographic editorial departments want to attract the recipients' attention, evoke emotions and get them to read their stories. But what exactly is a good picture that meets these expectations? Which criteria are decisive for selecting pictures and what effects of this selection can be measured on the recipients' side? This article presents the results of a research project carried out at the University of Erfurt in 2008 and conducted in collaboration with the German weekly magazine stern. It deals with the selection and impact of press photography by introducing the concept 'photo news factors'. Applying the traditional news value theory to pictures, photo news factors are defined as selection criteria that, on the part of the communicator, decide whether the press photos are worth publishing.

Genetically determined insulin resistance and subsequently impaired glucose uptake might explain both reduced fetal growth and elevated blood glucose. The glucose transporter 1 (GLUT!) plays an important role for fetal glucose uptake as well as for maternal-fetal glucose transfer, and it has been associated with insulin resistance in adults. The present study hypothesized that the common fetal GLUT1 XbaI polymorphism might reduce fetal insulin sensitivity and/or glucose supply in utero, thus affecting fetal blood glucose and fetal growth. Methods: A genetic association study was conducted at the obstetrics department of the Charite University Hospital, Berlin, Germany. 119.1 white women were included after delivery, and all newborns were genotyped for the GLUT1 XbaI polymorphism. Total glycosylated hemoglobin was quantified, serving as a surrogate of glycemia during the last weeks of pregnancy. Results: The analysis of this large population showed no significant differences in fetal glycosylated hemoglobin or birthweight for the different fetal GLUT1 XbaI genotypes. Only newborns carrying the mutated allele show the previously published inverse association between birthweight and glycosylated hemoglobin. Conclusions: The results suggest that there is no prenatal effect of the fetal GLUT1 XbaI polymorphism on fetal insulin sensitivity, intrauterine fetal glucose supply or fetal growth. However, the polymorphism seems to modulate the inverse interaction between birthweight and fetal glycemia.}, language = {en} }
