MATERIALS AND METHODS: Data of 50 consecutive patients, who underwent HPB surgery from 04/2018 to 07/2018 were prospectively collected for this study. During surgery, IOUS with a high-resolution ultrasound device using CEUS after bolus injection of 2.4-5 ml Sulphur hexafluoride microbubbles using a 6-9 MHz probe and a share wave and strain elastography was performed by an experienced examiner. Process and time analysis were carried out using mobile phone timer. RESULTS: The IOUS with CEUS and elastography correctly identified 42 malignant tumors and 4 benign lesions. In 3 cases, the examination provided false positive result (identifying 3 benign lesions as malignant) and in 1 case a malignant lesion was incorrectly assessed as benign (sensitivity 97,7\%, specificity 57,1\%, PPV 93,3\% and NPV 80\%). The specific question by the surgeon could be answered successfully in 98\% of the cases. In 76\% of the cases, there was a modification (42\%) or a fundamental change (34\%) of the planned surgical approach due to the information provided by the IOUS. Within the last group, the IOUS had a major impact on therapy outcome. In 7 patients an additional tumor resection was required, in 5 patients the tumor was assessed as inoperable, and in total in 5 patients an intraoperative RFA (4/5) or postoperative RITA (1/5) was required. Regarding procedural input, there was only a slight, but significant difference between the transport and set-up times before the intraoperative use (mean: 14 min 22 s) and the return transport (mean 13 min 6 s), (p = 0,038). The average examination time was 14 minutes, which makes only one third of the overall time demand. CONCLUSION: Combination of IOUS with CEUS and elastography in oncological HPB surgery provides valuable information that affects surgical decision-making. The procedural input of about 45 minutes seems to be a good investment considering the improvement of the surgical procedure and a significant modification of the therapy approach in the majority of the cases.}, language = {en} } @misc{PileckyKaemmerMathieuResugeetal., author = {Pilecky, Matthias and K{\"a}mmer, Samuel K. and Mathieu-Resuge, Margaux and Wassenaar, Leonard I. and Taipale, Sami J. and Martin-Creuzburg, Dominik and Kainz, Martin J.}, title = {Hydrogen isotopes (δ2H) of polyunsaturated fatty acids track bioconversion by zooplankton}, series = {Functional Ecology}, volume = {36}, journal = {Functional Ecology}, number = {3}, issn = {1365-2435}, doi = {10.1111/1365-2435.13981}, pages = {538 -- 549}, language = {en} } @misc{FehlingerMathieuResugePileckyetal., author = {Fehlinger, Lena and Mathieu-Resuge, Margaux and Pilecky, Matthias and Parmar, Tarn Preet and Twining, Cornelia W. and Martin-Creuzburg, Dominik and Kainz, Martin J.}, title = {Export of dietary lipids via emergent insects from eutrophic fishponds}, series = {Hydrobiologia}, volume = {Vol. 850}, journal = {Hydrobiologia}, number = {15}, issn = {1573-5117}, doi = {10.1007/s10750-022-05040-2}, pages = {3241 -- 3256}, language = {en} } @misc{PileckyMathieuResugeZavorkaetal., author = {Pilecky, Matthias and Mathieu-Resuge, Margaux and Z{\´a}vorka, Libor and Fehlinger, Lena and Winter, Katharina and Martin-Creuzburg, Dominik and Kainz, Martin J.}, title = {Common carp (Cyprinus carpio) obtain omega-3 long-chain polyunsaturated fatty acids via dietary supply and endogenous bioconversion in semi-intensive aquaculture ponds}, series = {Aquaculture}, volume = {561}, journal = {Aquaculture}, issn = {0044-8486}, doi = {10.1016/j.aquaculture.2022.738731}, pages = {1 -- 9}, language = {en} } @misc{BoetzlSponslerAlbrechtetal., author = {Boetzl, Fabian and Sponsler, Douglas and Albrecht, Matthias and Bat{\´a}ry, P{\´e}ter and Birkhofer, Klaus and Knapp, Michal and Krauss, Jochen and Maas, Bea and Martin, Emily A. and Sirami, Cl{\´e}lia and Sutter, Louis and Bertrand, Colette and Baillod, Aliette and Bota, Gerard and Bretagnolle, Vincent and Brotons, Llu{\´i}s and Frank, Thomas and Fusser, Moritz and Giralt, David and Gonz{\´a}lez, Ezequiel and Hof, Anouschka and Luka, Henryk and Marrec, Ronan and Nash, Michael and Ng, Katherina and Plantegenest, Manuel and Poulin, Brigitte and Siriwardena, Gavin and Zubair-Anjum, Muhammad and Entling, Martin and Steffan-Dewenter, Ingolf and Schirmel, Jens}, title = {Distance functions of carabids in crop fields depend on functional traits, crop type and adjacent habitat: a synthesis}, series = {Proceedings Royal Society.

The phenol moiety of the latter compound was then enzymatically oxidized into phenoxy radicals and a quinoid cation, which initiated the autocatalytic cleavage of the dimer and the formation of monomers such as 2-methoxy-1,4-benzoquinone and phenoxyl-substituted propionic acid. The introduction of 18O from H218O2 and H218O at different positions into the products provided information about the routes of ether cleavage.

Reactions included the hydroxylation of aromatic rings and aliphatic side chains, as well as O- and N-dealkylations and exhibited different regioselectivities depending on the particular APO used. At best, desired HDMs were obtained in yields greater than 80\% and with isomeric purities up to 99\%. Oxidations of tolbutamide, acetanilide and carbamazepine in the presence of H₂¹⁸O₂ resulted in almost complete incorporation of ¹⁸O into the corresponding products, thus establishing that these reactions are peroxygenations. The deethylation of phenacetin-d₁ showed an observed intramolecular deuterium isotope effect [(k(H)/k(D))(obs)] of 3.1±0.2, which is consistent with the existence of a cytochrome P450-like intermediate in the reaction cycle of APOs.

The aims of this gender-sensitive qualitative study will be to build on the existing body of literature and to provide qualitative evidence on the contexts and mechanisms of PSC for male and female UMRs in Germany by comparing two German regions. Methods and analysis: Following the study preparing realist review, a qualitative study will be undertaken in Berlin and Central German cities. Approximately 24 experts from the field of PSC and 12 lay UMRs will participate in face-to-face, semistructured interviews. Data will be transcribed and analysed based on the grounded theory research paradigm. Ethics and dissemination: Only participants who have been informed in both German and their native tongue and who have signed a declaration of consent will be included in the study. The study will comply rigorously with German data protection standards. Approval from the Ethical Review Committee at Martin Luther University Halle-Wittenberg, Germany has been obtained and granted. The results of the study will be presented at several conferences and will be published in high-quality, peer-reviewed international journals.

We investigated how the presence ofsemi-natural grasslands, the number of woody elements and the composition of the wider agricultural landscape affect bird spe-cies richness, true diversity (exponential Shannon diversity) and species composition. Bird communities were surveyed fourtimes on 16 paired transects of 250 m each with 8 transects placed between a cropfield and a semi-natural grassland and 8transects between two cropfields with no semi-natural grasslands in the vicinity. The number of woody elements around trans-ects was selected as an important predictor in all models, having a positive effect on species richness and true diversity, whilethe local presence of semi-natural grasslands was not selected in the best models. However, species richness and true diversityincreased with increasing cover of ley and semi-natural grasslands, whereas species composition was modified by the coverageof winter wheat at the landscape scale. Furthermore, bird species richness, true diversity and species composition differedbetween sampling dates. As bird diversity benefited from woody elements, rather than from the local presence of semi-naturalgrasslands as such, it is important to maintain woody structures in farmland. However, the positive effect of grassland at thelandscape scale highlights the importance of habitat variability at multiple scales. Because species richness and true diversitywere affected by different landscape components compared to species composition, a mosaic of land-use types is needed toachieve multiple conservation goals across agricultural landscapes.}, language = {en} } @misc{UlrichKohlerSpalleketal., author = {Ulrich, Hanna-Sophie and Kohler, Emma and Spallek, Jacob and Richter, Matthias and Clauß, Daniel and Mlinarić, Martin}, title = {Explaining psychosocial care among unaccompanied minor refugees: a realist review}, series = {European child \& adolescent psychiatry}, volume = {31(2022)}, journal = {European child \& adolescent psychiatry}, number = {12}, issn = {1435-165X}, doi = {10.1007/s00787-021-01762-1}, pages = {1857 -- 1870}, abstract = {Research on the psychosocial care (PSC) of unaccompanied minor refugees (UMRs) has mainly taken a socioepidemiological approach and has focused on the perspectives of experts in the field.

Hence, each element of the design space must be evaluated with respect to its stress state. Therefore, the method prefers elements experiencing a bending or shear load over elements which are mainly subjected to membrane stresses. In order to determine the stress state of the elements, we use the principal stresses at the Gauss points. For demonstrating the feasibility of the new topology optimization approach, three academic examples are presented and discussed.

The temperature was measured for six times with an infrared thermometer at five standardized points of the knee joint. During application and till the last measurement subjects were immobilized. The applied cold application resulted in a significant decrease of temperature in all measuring points concerning the pre-post-comparison. 20 minutes after removing the cuff significant temperature increases in 3 measurement points, still keeping below starting level, were remarked. Furthermore it is evident that the temperature differences of the muscular measuring points are significantly higher than those of the not muscular measuring points. Besides a higher fat portion leads due to the isolation effect in relation to musculature to significantly fewer variations in temperature.

This kind of injury is mainly based on intrinsic factors such as structural overload which accounts for 17\% of all moderate and severe competition injuries. Following knee and ankle joint, hamstrings are the third most common structure to suffer from injuries. As previous reviews show, eccentric training, such as the Nordic Hamstring Exercise (NHE), can reduce hamstring injuries. However, in those reviews other sports in addition to soccer were also examined in one sample. Purpose: The aim of this review is to synthesize the best available evidence on the effectiveness of the NHE as an intervention in the prevention of hamstring injuries in soccer players. Methods: The search for the studies was done in the PubMed, PEDro, Cochrane Library and EB-SCO databases. There was no language or time restrictions. Titles, abstracts and full texts of the respective studies were verified by two independent reviewers and selected using the inclusion criteria. In addition, critical evaluation tools were used to assess the methodological qualities of the respective studies followed by data extraction in JBI SUMARI. Meta-analysis was performed. Results: Four studies were included in this systematic review. Three studies compared NHE as an intervention with conventional football training and one study conducted hamstring curls as a control intervention. The duration of the studies ranged from 2.5 to 6.75 months, with a total of 28312 NHE sessions and 25918 training sessions in the control groups. The intervention groups showed a total of 30 hamstring injuries and the control groups developed a total of 80 injuries. A sample of 1780 soccer players were examined, 909 in the intervention groups and 871 in the control groups. The overall mean odds' ratio was significantly below one (95\% CI, P= 0.335). The probability of suffering a hamstring injury was between 0.22 and 0.53 times lower in the intervention group than in the control group. The test for heterogeneity showed no significance (I² = 9). Conclusion(s): The NHE can help to reduce hamstring injuries in football players. However, due to the small number of studies included, the result should be interpreted with caution and more clinical studies should be conducted in the future. Implications: Looking at the total number of days lost per player in a season, professional football has a total of approximately 25,900 days lost, which is three times more than in other sports. Every injury is associated with lost time and additional costs. This review aimed to examine a cost-efficient exercise for its preventive effect.

These findings shed light on the immunometabolic dysregulation underlying obesity-associated immune dysfunction, highlighting potential targets for therapeutic intervention.}, language = {en} } @misc{KieneSchottMartinCreuzburgetal., author = {Kiene, Marvin and Schott, Matthias and Martin-Creuzburg, Dominik and Laforsch, Christian}, title = {Food quantity and quality modulates inducible defenses in a common predator-prey system}, series = {Limnology and Oceanography}, volume = {69}, journal = {Limnology and Oceanography}, number = {7}, issn = {1939-5590}, doi = {10.1002/lno.12595}, pages = {1546}, language = {en} } @misc{StrobelAlvaradoChavarinKnautetal., author = {Strobel, Carsten and Alvarado Chavarin, Carlos and Knaut, Martin and Albert, Matthias and Heinzig, Andr{\´e} and Gummadi, Likhith and Wenger, Christian and Mikolajick, Thomas}, title = {p-Type Schottky contacts for graphene adjustable-Barrier phototransistors}, series = {Nanomaterials}, volume = {14}, journal = {Nanomaterials}, number = {13}, editor = {Giannazzo, Filippo and Agnello, Simonpietro and Seravalli, Luca and Bondino, Federica}, publisher = {MDPI}, issn = {2079-4991}, doi = {10.3390/nano14131140}, abstract = {The graphene adjustable-barriers phototransistor is an attractive novel device for potential high speed and high responsivity dual-band photodetection. In this device, graphene is embedded between the semiconductors silicon and germanium. Both n-type and p-type Schottky contacts between graphene and the semiconductors are required for this device. While n-type Schottky contacts are widely investigated, reports about p-type Schottky contacts between graphene and the two involved semiconductors are scarce. In this study, we demonstrate a p-type Schottky contact between graphene and p-germanium. A clear rectification with on-off ratios of close to 10 3 (±5 V) and a distinct photoresponse at telecommunication wavelengths in the infrared are achieved. Further, p-type silicon is transferred to or deposited on graphene, and we also observe rectification and photoresponse in the visible range for some of these p-type Schottky junctions. These results are an important step toward the realization of functional graphene adjustable-barrier phototransistors.}, language = {en} } @article{RaulienFriedrichStrobeletal., author = {Raulien, Nora and Friedrich, Kathleen and Strobel, Sarah and Raps, Stefanie and Hecker, Friederike and Pierer, Matthias and Schilling, Erik and Lainka, Elke and Kallinich, Tilmann and Baumann, Sven and Fritz-Wallace, Katarina and Rolle-Kampczyk, Ulrike and Bergen, Martin von and Aigner, Achim and Ewe, Alexander and Schett, Georg and Cross, Michael and Rossol, Manuela and Wagner, Ulf}, title = {Glucose-oxygen deprivation constrains HMGCR function and Rac1 prenylation and activates the NLRP3 inflammasome in human monocytes}, series = {Science Signaling}, volume = {17}, journal = {Science Signaling}, number = {845}, publisher = {American Association for the Advancement of Science (AAAS)}, issn = {1945-0877}, doi = {10.1126/scisignal.add8913}, pages = {19}, abstract = {Hypoxia and low glucose abundance often occur simultaneously at sites of inflammation. In monocytes and macrophages, glucose-oxygen deprivation stimulates the assembly of the NLRP3 inflammasome to generate the proinflammatory cytokine IL-1β. We found that concomitant glucose deprivation and hypoxia activated the NLRP3 inflammasome by constraining the function of HMG-CoA reductase (HMGCR), the rate-limiting enzyme of the mevalonate kinase pathway. HMGCR is involved in the synthesis of geranylgeranyl pyrophosphate (GGPP), which is required for the prenylation and lipid membrane integration of proteins. Under glucose-oxygen deprivation, GGPP synthesis was decreased, leading to reduced prenylation of the small GTPase Rac1, increased binding of nonprenylated Rac1 to the scaffolding protein IQGAP1, and enhanced activation of the NLRP3 inflammasome. In response to restricted oxygen and glucose supply, patient monocytes with a compromised mevalonate pathway due to mevalonate kinase deficiency or Muckle-Wells syndrome released more IL-1β than did control monocytes. Thus, reduced GGPP synthesis due to inhibition of HMGCR under glucose-oxygen deprivation results in proinflammatory innate responses, which are normally kept in check by the prenylation of Rac1. We suggest that this mechanism is also active in inflammatory autoimmune conditions.}, language = {en} } @misc{StrobelAlvaradoChavarinVoelkeletal., author = {Strobel, Carsten and Alvarado Chavarin, Carlos and V{\"o}lkel, Sandra and Jahn, Andreas and Hiess, Andre and Knaut, Martin and Albert, Matthias and Wenger, Christian and Steinke, Olaff and Stephan, Ulf and R{\"o}hlecke, S{\"o}ren and Mikolajick, Thomas}, title = {Enhanced Electrical Properties of Optimized Vertical Graphene-Base Hot Electron Transistors}, series = {ACS Applied Electronic Materials}, volume = {5}, journal = {ACS Applied Electronic Materials}, number = {3}, issn = {2637-6113}, doi = {10.1021/acsaelm.2c01725}, pages = {1670 -- 1675}, abstract = {The arrival of high-mobility two-dimensional materials like graphene leads to the renaissance of former vertical semiconductor-metal-semiconductor (SMS) hot electron transistors.

In this study we report about a device that consists of amorphous silicon, graphene, and crystalline silicon. For the first time, this device is fabricated by a four-mask lithography process which leads to significant improvements in the device performance. A strongly increased common-emitter current gain of 2\% could be achieved while the on-off ratio improved to 1.6 × 105, which is already higher than predicted theoretically. This could be mainly attributed to better interface characteristics and decreased lateral dimensions of the devices. A cutoff frequency of approximately 26 MHz could be forecasted based on the DC measurements of the device.}, language = {en} } @misc{HenkSchymuraXue, author = {Henk, Martin and Schymura, Matthias and Xue, Fei}, title = {Packing minima and lattice points in convex bodies}, series = {Moscow Journal of Combinatorics and Number Theory}, volume = {10}, journal = {Moscow Journal of Combinatorics and Number Theory}, number = {1}, publisher = {Mathematical Sciences Publishers}, issn = {2640-7361}, doi = {10.2140/moscow.2021.10.25}, pages = {25 -- 48}, abstract = {Motivated by long-standing conjectures on the discretization of classical inequalities in the geometry of numbers, we investigate a new set of parameters, which we call packing minima, associated to a convex body K and a lattice Λ.

By means of this model, the programmers describe desired observations and influences with respect to the physical world without directly referencing physical devices.
