Full textAbstract:
Chromosomal locus 6q23 is strongly linked to type 2 diabetes (T2DM) and related features including insulin secretion in various ethnic populations. Connective tissue growth factor (CTGF) gene is an interesting T2DM candidate gene in this chromosome region. CTGF is a key mediator of progressive pancreatic fibrosis up-regulated in type 2 diabetes. In contrast,CTGFinactivation in mice compromises islet cell proliferation during embryogenesis. The aim of our study was to investigate an impact ofCTGFgenetic variation on pancreatic beta-cell function and T2DM pathogenesis. We studied the effect of a commonCTGFpolymorphism rs9493150 on the risk of the T2DM development in three independent German cohorts. Specifically, the association betweenCTGFpolymorphism and non-invasive markers of beta-cell area derived from oral glucose tolerance test was studied in subjects without diabetes. Neither in the Metabolic Syndrome Berlin Potsdam (MESYBEPO) study (n= 1026) (OR = 0.637, CI (0.387–1.050);p= 0.077) nor in the European Prospective Investigation into Cancer and Nutrition-Potsdam (EPIC-Potsdam) (n= 3049) cohort (RR = 0.77 CI (0.49–1.20),p= 0.249 for the recessive homozygote in general model), a significant association with increased diabetes risk was observed. The risk allele of rs9493150 had also no effect on markers of beta-cell area in the combined analysis of the MESYBEPO and Tübingen Family Study (n= 1826). In conclusion, the polymorphism rs9493150 in the 5’-untranslated region of theCTGFgene has no association with T2DM risk and surrogate markers of beta-cell area.

Full textAbstract:
Three new types of arthropod are described from Cambrian intertidal lithofacies of the Elk Mound Group and St. Lawrence Formation of Wisconsin and the Potsdam Group of Quebec. These arthropods are preserved ventrally in sandstone in life position and in three dimensions, allowing detailed characterization of limb morphologies, labrums, and other organs such as eyes. A taphonomic model is presented, illustrating this unusual, uncompressed, three-dimensional style of preservation. Arenosicaris inflata n. sp., from the Terreneuvian-Furongian Elk Mound Group and the Furongian St. Lawrence Formation, is the earliest unambiguous occurrence of a malacostracan phyllocarid. This 3 cm long arthropod had ovate valves, five pairs of biramous pleopods, and at least 3 pairs of thoracopods. Mosinieia macnaughtoni n. sp., a large (>10 cm long) euthycarcinoid of uncertain affinity with flattened or paddle-like appendages also occurs in Elk Mound strata. Mictomerus melochevillensis n. sp. represents a new euthycarcinoid family and is the first known non-trilobite arthropod from the middle Cambrian-Furongian Potsdam Group of Quebec. M. melochevillensis n. sp. is large (8–10+ cm long), with as many as eleven pairs of well-preserved homopodous, uniramous, non-paddle-like limbs. Both M. macnaughtoni and M. melochevillensis differ substantially from previously known euthycarcinoids in limb morphology and represent the oldest known representatives of the group. Additionally, both M. melochevillensis n. sp. and M. macnaughtoni n. sp. possess morphologies that are consistent with abundant subaerial and subaqueous Diplichnites and Protichnites trackways known from these units, suggesting that these may be the earliest land-going animals.

Full textAbstract:
ObjectiveThe German Diabetes Risk Score (GDRS) is a diabetes prediction model which only includes non-invasively measured risk factors. The aim of this study was to extend the original GDRS by hemoglobin A1c (HbA1c) and validate this clinical GDRS in the nationwide German National Health Interview and Examination Survey 1998 (GNHIES98) cohort.Research design and methodsExtension of the GDRS was based on the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam study with baseline assessment conducted between 1994 and 1998 (N=27 548, main age range 35–65 years). Cox regression was applied with the original GDRS and HbA1c as independent variables. The extended model was evaluated by discrimination (C-index (95% CI)), calibration (calibration plots and expected to observed (E:O) ratios (95% CI)), and reclassification (net reclassification improvement, NRI (95% CI)). For validation, data from the GNHIES98 cohort with baseline assessment conducted between 1997 and 1999 were used (N=3717, age range 18–79 years). Missing data were handled with multiple imputation.ResultsAfter 5 years of follow-up 593 incident cases of type 2 diabetes occurred in EPIC-Potsdam and 86 in the GNHIES98 cohort. In EPIC-Potsdam, the C-index for the clinical GDRS was 0.87 (0.81 to 0.92) and the overall NRI was 0.26 (0.21 to 0.30), with a stronger improvement among cases compared with non-cases (NRIcases: 0.24 (0.19 to 0.28); NRInon-cases: 0.02 (0.01 to 0.02)). Almost perfect calibration was observed with a slight tendency toward overestimation, which was also reflected by an E:O ratio of 1.07 (0.99 to 1.16). In the GNHIES98 cohort, discrimination was excellent with a C-index of 0.91 (0.88 to 0.94). After recalibration, the calibration plot showed underestimation of diabetes risk in the highest risk group, while the E:O ratio indicated overall perfect calibration (1.02 (0.83 to 1.26)).ConclusionsThe clinical GDRS provides the opportunity to apply the original GDRS as a first step in risk assessment, which can then be extended in clinical practice with HbA1c whenever it was measured.

Full textAbstract:
Cyclic activated sludge technology was selected for the Potsdam Wastewater Treatment Plant (90,000 p.e.). The cyclic activated sludge facility comprises four modules integrated into two circular basins. Construction was commenced in February 1998 with seeding of the plant for start up taking place in October 1998. Process performance has been met since Spring 1999 at 80-90% of design load. In order to optimize start-up procedures, respiration rates were used as a guidance for process stabilization and online process optimization during normal operation. Operation for co-current nitrification denitirification provided an ammonia removal of 1.1 mg NH4-N/gMLSS · h (15°C) and a corresponding nitrate respiration rate of 0.85 mg NO3-N/gMLSS · h under aerated conditions. Enhanced biological phosphorus removal generated an effluent mean total phosphorus concentration of 0.38 mg/L without precipitant addition.

AbstractObjectiveTo assess the feasibility of combining short-term and long-term dietary assessment instruments as new concept for improving usual dietary intake assessment on the individual level.DesignFeasibility study of completing three 24 h dietary recalls (24-HDR) and a self-administered food propensity questionnaire (FPQ). The 24-HDR was conducted by monthly telephone interviews, using EPIC-SOFT software. The FPQ was completely standardized across cohorts and offered either as a web-based tool or in paper format.SettingRandom sample derived from five ongoing European cohort studies (EPIC-San Sebastian, EPIC-Florence, EPIC-Potsdam, Estonia Genome Center (EGC) and Norwegian Women and Cancer study (NOWAC)).SubjectsA total of 400 participants.ResultsOverall, the total participation rate for the present study was 65·3 % (n 261). On average, completion of the 24-HDR was highest for the first 24-HDR (63·0 %) and decreased slightly for the second (60·3 %) and third 24-HDR (56·3 %). The proportions of selecting the web-based FPQ varied among the study centres, with the highest in EGC (92·9 %) and NOWAC (70·0 %) and the lowest in EPIC-San Sebastian (25·5 %) and EPIC-Potsdam (33·9 %). Web users rarely requested support and were younger and more highly educated than those who completed the paper format.ConclusionsThe present study supports the feasibility of a combined application of three 24-HDR and an FPQ in culturally different populations. The varying acceptance of the web-based instrument across populations requires a flexible application of assessment instruments.

Full textAbstract:
On January 8, 1998, a severe ice storm devastated electrical power grids and caused extensive environmental damage in the northeastern United States and southeastern Canada. This study examines the effect this natural disaster had on perceptions of social relations in the village of Potsdam, a rural community in northern New York State. Residents (N = 88) were surveyed on their perceptions of their community one month following the disaster. These data are compared with a survey (N = 127) of community perceptions conducted three. years prior to the disaster. These two surveys provide a rare opportunity to perform a longitudinal study of the effects of the disaster on social cohesion. Findings indicate that social cohesion increases in the immediate aftermath of the disaster. However, one month after the disaster, perceptions of the community return to predisaster levels. This study indicates that there are few lasting effects on social cohesion resulting from a natural disaster.

Full textAbstract:
Abstract. Biological nitrogen fixation (BNF) from grain legumes is of significant importance in global agricultural ecosystems. Crops with BNF capability are expected to support the need to increase food production while reducing nitrogen (N) fertilizer input for agricultural sustainability, but quantification of N fixing rates and BNF crop yields remains inadequate on a global scale. Here we incorporate two legume crops (soybean and faba bean) with BNF into a dynamic vegetation model LPJ-GUESS (Lund–Potsdam–Jena General Ecosystem Simulator). The performance of this new implementation is evaluated against observations from a range of water and N management trials. LPJ-GUESS generally captures the observed response to these management practices for legume biomass production, soil N uptake, and N fixation, despite some deviations from observations in some cases. Globally, simulated BNF is dominated by soil moisture and temperature, as well as N fertilizer addition. Annual inputs through BNF are modeled to be 11.6±2.2 Tg N for soybean and 5.6±1.0 Tg N for all pulses, with a total fixation of 17.2±2.9 Tg N yr−1 for all grain legumes during the period 1981–2016 on a global scale. Our estimates show good agreement with some previous statistical estimates but are relatively high compared to some estimates for pulses. This study highlights the importance of accounting for legume N fixation process when modeling C–N interactions in agricultural ecosystems, particularly when it comes to accounting for the combined effects of climate and land-use change on the global terrestrial N cycle.

Abstract Purpose We aimed to examine the prospective association between manganese, iron, copper, zinc, iodine, selenium, selenoprotein P, free zinc, and their interplay, with incident type 2 diabetes (T2D), cardiovascular disease (CVD) and colorectal cancer (CRC). Methods Serum trace element (TE) concentrations were measured in a case-cohort study embedded within the EPIC-Potsdam cohort, consisting of a random sub-cohort (n = 2500) and incident cases of T2D (n = 705), CVD (n = 414), and CRC (n = 219). TE patterns were investigated using principal component analysis. Cox proportional hazard models were fitted to examine the association between TEs with T2D, CVD and CRC incidence. Results Higher manganese, zinc, iodine and selenium were associated with an increased risk of developing T2D (HR Q5 vs Q1: 1.56, 1.09–2.22; HR per SD, 95% CI 1.18, 1.05–1.33; 1.09, 1.01–1.17; 1.19, 1.06–1.34, respectively). Regarding CVD, manganese, copper and copper-to-zinc ratio were associated with an increased risk (HR per SD, 95% CI 1.13, 1.00–1.29; 1.22, 1.02–1.44; 1.18, 1.02–1.37, respectively). The opposite was observed for higher selenium-to-copper ratio (HR Q5 vs Q1, 95% CI 0.60, 0.39–0.93). Higher copper and zinc were associated with increasing risk of developing CRC (HR per SD, 95% CI 1.29, 1.05–1.59 and 1.14, 1.00–1.30, respectively). Selenium, selenoprotein P and selenium-to-copper-ratio were associated to decreased risk (HR per SD, 95% CI 0.82, 0.69–0.98; 0.81, 0.72–0.93; 0.77, 0.65–0.92, respectively). Two TE patterns were identified: manganese–iron–zinc and copper–iodine–selenium. Conclusion Different TEs were associated with the risk of developing T2D, CVD and CRC. The contrasting associations found for selenium with T2D and CRC point towards differential disease-related pathways.

Ismail Ibrahem and Armando Córdova of Mid Sweden University and Stockholm University prepared (Adv. Synth. Catal. 2011, 353, 3114) 6 by combining three catalysts to effect the enantioselective addition of 5 to 4. Giovanni Casiraghi and Franca Zanardi of the Università degli Studi di Parma used (J. Org. Chem. 2011, 76, 10291) a silver catalyst to mediate the addition of 8 to 7 to give 9. Keiji Maruoka of Kyoto University condensed (Nature Chem. 2011, 3, 642) the diazo ester 10 with an aldehyde 4, leading, after reduction of the initial adduct and protection, to the diamine 11. Christoph Schneider of the Universität Leipzig effected (Synthesis 2011, 4050) the vinylogous addition of 13 to an imine 12, setting both stereogenic centers of 14. In the course of the coupling of 16 with the diol 15, Michael J. Krische of the University of Texas established (J. Am. Chem. Soc. 2011, 133, 12795) four new stereogenic centers. By adding (Chem. Commun. 2011, 47, 10557) an α-nitro ester 18 to the maleimide 19, Professor Maruoka established both the alkylated secondary center and the N-substituted quaternary center of 20. Srinivas Hotha of the Indian Institute of Science Education & Research and Torsten Linker of the University of Potsdam showed (Chem. Commun. 2011, 47, 10434) that the readily prepared lactone 21 could be opened to 23 without disturbing the stereogenic center adjacent to the carbonyls. Allan D. Headley and Bukuo Ni of Texas A&M University-Commerce devised (Synthesis 2011, 1993) a recyclable catalyst for the addition of an aldehyde 7 to a nitroalkene 24 in water to give 25. Alexandre Alexakis of the University of Geneva effected (Chem. Commun. 2011, 47, 7212) the triply convergent coupling of 26, 27, and 28 to give 29 as a single dominant diastereomer.

Full textAbstract:
The conditions for the appearance of cavitation, i.e. the local vaporization of fluid under static or dynamic stresses, are closely connected with the tensile strength of the fluid (Arndt, Keller (1992)). Although the dominant effect of water quality on the cavitation interception has been known for many years (Keller (1981, 1983, 1984)), it is uncommon to measure its stress resistance. A possible reason for that could be the unique stress-resistance probe of Keller (1987, 1994) (Eickmann (1992)), which by itself represents a great engineering break-through, is rather complex and expensive. It has become clear during the ASME/JASME conference in San Francisco, 1999 (Keller, Rott, Striedinger, Awad, Ludwig, Yang, Li), and the Fourth International Symposium on Cavitation in Pasadena 2001 (Keller), that internationally standardized testing conditions are required with respect to water quality (Heller (2000)). A relatively simple method of concurrently measuring tensile strength or cavitation susceptibility in cavitation channels has been developed at the Institute of Fluid Mechanics of the Technische Universita¨t Dresden during the last months. This newly developed tensile strength measuring technique is not only efficient and cheap but can also be installed in any existing cavitation channel with comparably small effort. The presented paper represents the actual developmentstate of the Dresden measuring device. Comparison measurements at the cavitatio n-channels of the Versuchsanstalt Obernach (Dr. Keller), Schiffsbau-Versuchsanstalt Potsdam (Mr. Heinke) and the Schiffsbau-Versuchsanstalt Hamburg (Mr. Friesch) are planed for the following months.

When the documentary bases are photographs it is possible to carefully model the recorded elements using photogrammetry techniques based on 3D primitives, so that by means of an immersive navigation limited to certain points of view, an appearance of acceptable tridimensionality is obtained, where only isolated images of dispersed frames are available. The virtual recreation can be completed increasing its realistic appearance through its edition with animations of objects (for example, carriages) and characters, texts, musical setting, etc. The results can be presented in formats such as video or navigation through virtual reality helmets. From a selection of the first historical photographs of the Plaza de la Virgen, that we have obtained searching in several documentary sources, our multidisciplinary team is interested in a reliable, realistic and pleasant presentation of the urban environment of one of the most representative places in the city of Valencia, whose spatial configuration has changed significantly over the years.
