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{FoersterSchenkZollneretal., author = {F{\"o}rster, Stefan and Schenk, Sebastian and Zollner, Eva Maria and Krahn, Oliver and Chiang, Cheng-Tien and Schumann, Florian O. and Bayat, Alireza and Schindler, Karl-Michael and Trautmann, Martin and Hammer, Ren{\´e} and Meinel, Klaus and Adeagbo, Waheed A. and Hergert, Wolfram and Flege, Jan Ingo and Falta, Jens and Ellguth, Martin and Tusche, Christian and DeBoissieu, Marc and Muntwiler, Matthias and Gerber, Thomas and Widdra, Wolf}, title = {Quasicrystals and their Approximants in 2D Ternary Oxides}, series = {Physia Status Solidi B}, volume = {257}, journal = {Physia Status Solidi B}, number = {7}, issn = {0370-1972}, doi = {10.1002/pssb.201900624}, pages = {11}, abstract = {2D oxide quasicrystals (OQCs) are recently discovered aperiodic, but well-ordered oxide interfaces.

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. Studies with a 14C-labeled lignin model dimer showed that more than 70\% of the intermediates formed were further coupled to form polymers with molecular masses above 10 kDa.

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 formal potential E ° ′ of AaeAPO in the gold nanoparticles-chitosan film was estimated to be -(286 ± 9) mV at pH 7.0. The heterogeneous electron transfer rate constant (ks) increases from 3.7 in the scan rate range from 0.2 to 3.0 V s-1 and level off at 63.7 s-1. Furthermore, the peroxide-dependent hydroxylation of aromatic compounds was applied to develop a sensor for naphthalene and nitrophenol. The amperometric measurements of naphthalene are based on the indication of H2O2 consumption.

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.
