BART: A multilingual anaphora resolution system
BART (Versley et al., 2008) is a highly mod-
ular toolkit for coreference resolution that
supports state-of-the-art statistical approaches
and enables efficient feature engineering. For
the SemEval task 1 on Coreference Resolution, BART runs have been submitted for German, English, and Italian.
BART relies on a maximum entropy-based classifier for pairs of mentions. A novel entity-mention approach based on Semantic Trees is
at the moment only supported for English
 α-Cyclodextrin dimer complexes of dopamine and levodopa derivatives to assess drug delivery to the central nervous system: ADME and molecular docking studies
Sergey Shityakov, Jens Broscheit, Carola FörsterDepartment of Anesthesiology and Critical Care, University of Würzburg, Würzburg, GermanyAbstract: This paper attempts to predict and emphasize molecular interactions of dopamine, levodopa, and their derivatives (Dopimid compounds) containing 2-phenyl-imidazopyridine moiety with the α-cyclodextrin dimer in order to assess and improve drug delivery to the central nervous system. The molecular docking method is used to determine the energetic profiles, hydrogen bond formation, and hydrophobic effect of 14 host–guest complexes. The results show that the “chemical branching” represented by additional ethyl-acetate residue is energetically unfavorable and promotes a conformational shift due to the high root mean square deviation levels. This phenomenon is characterized by a low number of H-bonds and a significant decrease of the host–guest hydrophobic potential surface. Finally, the overall docking procedure presents a powerful rationale for screening and analyzing various sets of promising drug-like chemical compounds in the fields of supramolecular chemistry, molecular sensing, synthetic receptors, and nanobiotechnology.Keywords: dopamine, levodopa, Dopimid compounds, α-CD dimer, molecular docking, complexatio

Invasive monitoring of the clinical effects of high intra-abdominal pressure for insertion of the first trocar.
Background: To analyze the effects of transitory, high intra-abdominal pressure on clinical, hemodynamic, blood gas and metabolic parameters.

Methods: Sixty-seven laparoscopic patients were divided into groups P12 (n = 30, maximum intra-abdominal pressure of 12 mmHg) and P20 (n = 37, maximum intra-abdominal pressure of 20 mmHg). Through radial artery cannulation, mean arterial pressure (MAP) was assessed and blood gas analysis – pH, arterial oxygen tension (PaO2), arterial carbon dioxide tension (PaCO2), bicarbonate (HCO3) and base excess (BE) – was performed. These parameters were evaluated in both groups at time point zero, before CO2 insufflation; at time point one (TP1), when intra-abdominal pressure of 12 mmHg was reached in both groups; at time point two (TP2), 5 minutes after reaching intra-abdominal pressure of 12 mmHg in group P12 and of 20 mmHg in group P20; and at time point three (TP3), 10 minutes after reaching intra-abdominal pressure of 12 mmHg in group P12 and 10 minutes after TP1 in group P20, when intra-abdominal pressure decreased from 20 mmHg to 12 mmHg. Values out of the normal range or the occurrence of atypical phenomena suggestive of organic disease indicated clinical changes.

Results: Significant variations in MAP, pH, HCO3 and BE were observed in group P20; these changes, however, were within normal limits. Clinical changes were also within normal limits, and no pathological phenomena were observed.

Conclusions: Brief, intra-abdominal hypertension for the insertion first trocar insertion causes variations in MAP, pH, HCO3 and BE without adverse effects, and it may protect from iatrogenic injury
Impact of Preceded Tumor Therapeutic Irradiation on the Microtensile Bond Strength of Universal Adhesives Applied in Self-Etch Mode to Human Dentin In Vitro
The aim of this study was to investigate the effect of preceded tumor therapeutic irradiation on the tensile bond strength of three modern universal adhesives applied in self-etch mode on dentin. Specimens prepared from 135 extracted human third molars were divided into three superior groups. These received either no radiation, 5 Gy, or a total dose of 60 Gy in vitro irradiation, fractionally applied. The samples of each group were further randomly assigned to six subgroups to test three adhesives (Futurabond® U, Voco; AdheSE® Universal Ivoclar Vivadent; Xeno® Select, Dentsply Sirona) in the self-etch application mode (n = 15). Tensile bond strength was determined using a universal testing machine (1.0 mm/min). Data were analyzed with ANOVA (p < 0.01) and Tukey’s test (p < 0.05). The influence of irradiation on the microtensile bond strength of the used dentin adhesives proved to be significant. For each material, a decrease in adhesion value was registered after irradiation. However, only for the material Xeno® Select were significantly reduced adhesion values determined after irradiation with 60 Gy compared to 0 Gy. Within the limitations of an in vitro study, some effects of tumor therapeutic irradiation of human dentin on the tensile bond strength of universal adhesives used in self-etch mode could be observed. Those decreases were only partly significant, depending on the material and the radiation dose. Whether the tensile bond strength on irradiated dentin depends on the particular application mode (etch-and-rinse vs. self-etch) of the universal adhesives remains to be investigated

НЕЙРОКОГНИТИВНЫЕ НАРУШЕНИЯ У ПАЦИЕНТОВ С ВИСЦЕРАЛЬНЫМ ОЖИРЕНИЕМ В ПЕРИОПЕРАЦИОННОМ ПЕРИОДЕ КОРОНАРНОГО ШУНТИРОВАНИЯ
Visceral obesity (VO) is a predictor of complications after coronary artery bypass grafting (CABG), and a risk factor for cognitive and psychological disorders.Purpose. Of our study was to investigate features of neurocognitive disorders and their interactions in patients with VO in a perioperative period of CABG.Materials and methods. 90 patients with a body mass index from 25 to 35 kg/m2 were included in the study, they had indications for CABG. VO was assessed in terms of «waist circumference/hip circumference» (WC/HC). Group 1 included patients with VO (WC/HC >0.9 for men and WC/HC >0.85 for women), Group 2 – patients without VO (WC/HC ≤0,9 for men and WC/HC ≤0,85 for women). Cognitive functions were evaluated with the use of the automated complex software Status PF (Kemerovo,Russia). The Spielberger State-Trait Anxiety Inventory (STAI-T, STAI-S) was used for an estimation of anxiety.Results. Group 1 showed statistically lower rates of attention and neurodynamics and higher levels of depression and anxiety in the perioperative period of CABG. Group 1 demonstrated the decrease in memory and neurodynamics scores as STAI-T levels were higher in the perioperative period of CABG; the growth of STAI-T levels in Group 2 did not always lead to the derangements of attention and neurodynamics scores. Moreover, in Group 2 higher attention and neurodynamics scores were at higher STAI-T levels in 6 months after CABG. High STAI-S levels in both groups negatively affected the performance of attention and neurodynamics in the perioperative period of CABG.Conclusion. Patients with VO have a higher risk of developing neurocognitive disorders in the perioperative period of CABG.
