Abstract
e24107 Background: Despite many years of clinical research and development, nausea and vomiting remain challenging toxicities related to chemotherapy. The aim of our study was assessment of non-pharmacological, patient-related risk factors for chemotherapy-induced nausea and vomiting and development of unique predictive score in patients with gynaecological malignancies planned for chemotherapy. Methods: A research-based questionnaire of 27 risk factors was generated and provided to patients diagnosed with gynaecological malignancies prior to indicated chemotherapy. The data on nausea and vomiting from at least 3 cycles therapy was collected. Variable selection via stepwise and LASSO regression combined with patients history was used to identify a small set of questions with high predictive power. As risk prediction model, a Bayesian logistic regression was implemented with a cut-off chosen to yield a sensitivity of 80%. Area under the curve analysis (AUC) was conducted, and accuracy of prediction was calculated. Results: In total 191 patients were enrolled. The most frequent diagnosis and chemotherapy was ovarian cancer (69%) and carboplatinum/paclitaxel combination (57.7%), respectively. Six factors (emetogenic potential of the therapy, educational status, nausea and vomiting due to other medication, motion sickness, anxiety from therapy in general and anxiety from nausea due to therapy) were identified as most important predictive factors. All questions were answered by 132 (69.1%) patients. Among those 97 (68%) reported nausea or vomiting. The AUC of the predictive score consisting mentioned factors was 0.741, with a sensitivity of 80.4%, specificity of 51.4% and an overall accuracy of 72.7%. Conclusions: Patients related risk factors are missing in selection of the antiemetic prophylaxis in patients under chemotherapy. Presented predictive score showed very promising predictive power and is going to be validated in further phase of the trial. Clinical trial information: DRKS-ID: DRKS00015151.

Abstract
We describe mono-substituted helical poly(phenyl)acetylene, a structural variation of polyacetylene that may overcome its problem: the lack of chemical stability. Helical polyacetylene shows an intrinsic stiff rod structure, which can be enhanced by the choice of suitable side groups. The structure looks like a narrow spiral with a conjugated electron system, covered by attached side groups spiralling in the opposite sense. We consider this unique material as a prototype for molecular electronic device use. It provides the electronic function, mechanical packaging and electrical insulation through a variety of side groups and exhibits useful self-assembly properties. We provide evidence that such materials, in many variations, show the expected overall structure, can be synthesized through living polymerization (which is necessary for the fabrication of monomers by monomer controlled structures), do show enhanced chemical stability, are amenable to self-assembly, may be deposited in an oriented fashion and do show electrical conductivity.

Abstract
Tissue inhibitor of metalloproteinases (TIMP)-1 and TIMP-2 are proteins with proteinase-inhibiting and cytokine properties. TIMP-1 is active primarily in B cells and B-cell lymphomas, whereas TIMP-2 expression is restricted to T cells. The expression of TIMP-1 and TIMP-2 in lymph nodes from patients with Hodgkin disease (HD) and in Hodgkin-derived cell lines was investigated. In situ hybridization showed TIMP-1 RNA expression in 3% to 80% of Hodgkin/Reed-Sternberg (H/R-S) cells from 14 of 15 patients, with results in one patient being at the lowest detection limit; no expression of TIMP-2 in H/R-S cells; and only weak expression of TIMP-2 in reactive lymphoid tissue. Production of TIMP-1 protein by H/R-S cells was accordingly found on immunohistochemical analysis of lymph nodes from patients with HD. There was only low expression of matrix metalloproteinase (MMP)-2, which is mainly inhibited by TIMP-2; no expression of MMP-1 and MMP-3 in reactive lymphoid tissue; and no expression of these MMPs in H/R-S cells. Thus, TIMP-1 expression in lymph nodes was not correlated with metalloproteinase expression. Five of 7 Hodgkin-derived cell lines expressed TIMP-1 at the protein level. Only one of these cell lines expressed TIMP-2, at the lowest detection limit. TIMP-1 levels in plasma from patients with HD were within the same range as those in plasma from healthy controls. Recombinant human TIMP-1 inhibited induced cell death in Hodgkin-derived cell lines in vitro. TIMP-1 and TIMP-2 inhibited T-cell cytotoxicity against autologous cells presenting tumor-associated antigens and in allogeneic mixed lymphocyte cultures. Thus, TIMP-1, aside from its role in proteinase equilibrium, is an autocrine and paracrine survival factor for H/R-S cells and an immunosuppressive protein expressed in Hodgkin lymphomas.

Abstract
Recommendations for vitamin K supplementation were recently changed to 3 x 1 mg orally in healthy term neonates and 0.2 mg parenterally in prematures and high-risk neonates. Prothrombin times (PT) at reduced vitamin K doses (120 patients, 170 samples) during the first 6 weeks of life were below 40% in 6 patients only; all low PTs were unrelated to vitamin K. In the remaining patients, median PT was 100%; 79% of patients had values above 70%. PT was related to birthweight, gestational age and age. There was no decrease over the observation period. Following reduced oral and parenteral vitamin K regimens PTs were well within published reference values for neonates given larger amounts of vitamin K.

Abstract
Abstract
We describe three biomonitoring studies in which hemoglobin (Hb) adducts were used as biochemical markers to assess indirectly the target dose of genotoxic chemicals. We monitored the exposure to 1,3-butadiene in occupationally exposed workers and in two control groups by analyzing the adducts formed by the reaction of the first activation product, butadiene monoepoxide, with the terminal valine of Hb; we also measured hydrolyzable adducts formed by the reaction of metabolically formed nitroso derivatives with Hb from five selected nitropolycyclic aromatic hydrocarbons (1-nitropyrene; 2-nitrofluorene, 3-nitrofluoranthrene, 6-nitrochrysene, and 9-nitrophenanthrene) in coke oven workers of different job categories and control workers of the same geographical area. We detected hydrolyzable adducts from monocyclic nitroarenes in blood from individuals living in a contaminated area where explosives had been produced and from controls. The contaminants considered were 2,4,6-trinitrotoluene; 2,4- and 2,6-dinitrotoluene; and 1,3-dinitrobenzene. Differences between groups were significant, but interindividual variation was great and back-ground exposures must be considered.

Abstract
One of the best investigated binary lipid mixtures is the lecithin-cholesterol system. We show here that it is possible to modify the cholesterol in such a way that it can be polymerized without changing its behaviour in mixtures with lecithin. The polymerizable derivatives exhibit a very similar phase diagram in the mixture with dipalmitoylphosphatidylcholine as the cholesterol itself. This is demonstrated by filmbalance measurements.

Abstract
Phospholipids (phosphatidylcholines) with diacetylene in each acyl chain have been deposited in Langmuir-Blodgett multilayers on a variety of substrates. Upon irradiation the diacetylene groups polymerise and link the phospholipid molecules together with a conjugated chain made up of alternating single, double and triple bonds. Advantage has been taken of this polymerisation process to increase the stability of these lipids layers and to produce stable biomembrane hydrophilic surface. These surfaces may be useful for studies of blood coagulation and protein adsorption. In addition they could also have medical application.

Abstract
The perianal region of 294 healthy persons (151 male, 143 female) of different age was examined and the size, the localization and the number of the skin tags were registered. The frequency increases in women especially at the beginning of the second decade and in men especially at the fourth decade of life. 80% of all women and 60% of all men have skin tags. The size of the skin tag increases while the person becomes older. In the average women have bigger skin tags than men. Most of the skin tags are located in the region of 12 and 6 h lithotomy position.
