Abstract
Under atmospheric conditions, nitrate-RO2 radicals are equilibrated and react predominantly with HO2, RO2 and NO. The nitrate-RO chemistry is affected strongly by ring closure to epoxy radicals, impeding formation of MVK/MACR.

Abstract
Backround The primary aim of this study was to investigate information needs and treatment preferences of patients with ovarian cancer, focusing especially on physician-patient relationship and treatment. Patients and methods A questionnaire was developed based on the experiences of the national German survey 'Expression II', and was provided to patients with ovarian cancer either at initial diagnosis or with recurrent disease via Internet (online-version) or as print-out-version. Results From December 2009 to October 2012, a total of 1830 patients with ovarian cancer from eight European countries (Austria, Belgium, France, Germany, Italy, Poland, Romania, Spain) participated, 902 (49.3%) after initial diagnosis and 731 (39.9%) with recurrent ovarian cancer. The median age was 58 years (range 17-89). Nearly all patients (96.2%) had experienced upfront surgery followed by first-line chemotherapy (91.8%). The majority of patients were satisfied with the completeness and comprehensibility of the explanation about the diagnosis and treatment options. The three most important aspects, identified by patients to improve the treatment for ovarian cancer included: 'the therapy should not induce alopecia' (42%), 'there must be more done to counter fatigue' (34.5%) and 'the therapy should be more effective' (29.7%). Out of 659 (36%) patients, who were offered participation in a clinical trial, 476 (26%) were included. Conclusion This study underlines the high need of patients with ovarian cancer for all details concerning treatment options irrespective of their cultural background, the stage of disease and the patient's age. Increased information requirements regarding potential side effects and treatment alternatives were recorded. Besides the need for more effective therapy, alopecia and fatigue are the most important side effects of concern to patients.

Abstract
Ambient measurements of PM1aerosol chemical composition at Cabauw, the Netherlands, implicate higher ammonium concentrations than explained by the formation of inorganic ammonium salts. This additional particulate ammonium is called excess ammonium (eNH4). Height profiles over the Cabauw Experimental Site for Atmospheric Research (CESAR) tower, of combined ground based and airborne aerosol mass spectrometric (AMS) measurements on a Zeppelin airship show higher concentrations ofeNH4at higher altitudes compared to the ground. Through flights across the Netherlands, the Zeppelin based measurements furthermore substantiateeNH4as a regional phenomenon in the planetary boundary layer. The excess ammonium correlates with mass spectral signatures of (di-)carboxylic acids, making a heterogeneous acid–base reaction the likely process of NH3uptake. We show that this excess ammonium was neutralized by the organic fraction forming particulate organic ammonium salts. We discuss the significance of such organic ammonium salts for atmospheric aerosols and suggest that NH3emission control will have benefits for particulate matter control beyond the reduction of inorganic ammonium salts.

Abstract
BACKGROUND This is the first study investigating the safety and efficacy of the trifunctional antibody catumaxomab administered i.p. at the end of cytoreductive surgery and postoperatively prior to standard chemotherapy in patients with primary epithelial ovarian cancer (EOC). METHODS Patients received i.p. catumaxomab 10 μg intraoperatively and 10, 20, 50 and 150 μg on days 7, 10, 13 and 16, respectively, postoperatively. After the study, patients received standard chemotherapy and were followed for 23 months. The primary endpoint was the rate of postoperative complications. RESULTS Forty-one patients entered the study and were evaluable for safety and 34 were alive at 24 months. Complete tumour resection rate was 68%. Postoperative complications were observed in 51%, the most common anastomotic leakage (7%) and wound infections (5%). The most common catumaxomab-related adverse events were abdominal pain, nausea, vomiting and pyrexia. Thirty-nine percent discontinued catumaxomab therapy, and 98% received chemotherapy post study. Kaplan-Meier estimates of disease-free and overall survival after 24 months were 56% and 85%, respectively. CONCLUSIONS Intra- and close postoperative catumaxomab seems feasible, but efficacy and safety were limited by postsurgical complications. In the future prospective trials are needed to investigate the best schedule of integration of catumaxomab into current treatment strategies for EOC.

Abstract
Because of its semi-solid character in dissemination and growth, advanced ovarian cancer with its hundreds of peritoneal tumor nodules and plaques appears to be an excellent in vivo model for studying the cancer stem cell hypothesis. The most important obstacle, however, is to adequately define and isolate these tumor-initiating cells endowed with the properties of anoikis-resistance and unlimited self-renewal. Until now, no universal single marker or marker constellation has been found to faithfully isolate (ovarian) cancer stem cells. As these multipotent cells are known to possess highly elaborated efflux systems for cytotoxic agents, these pump systems have been exploited to outline putative stem cells as a side-population (SP) via dye exclusion analysis. Furthermore, the cells in question have been isolated via flow cytometry on the basis of cell surface markers thought to be characteristic for stem cells.In the Vienna variant of the ovarian cancer cell line A2780 a proof-of-principle model with both a stable SP and a stable ALDH1A1+ cell population was established. Double staining clearly revealed that both cell fractions were not identical. Of note, A2780V cells were negative for expression of surface markers CD44 and CD117 (c-kit). When cultured on monolayers of healthy human mesothelial cells, green-fluorescence-protein (GFP)-transfected SP of A2780V exhibited spheroid-formation, whereas non-side-population (NSP) developed a spare monolayer growing over the healthy mesothelium. Furthermore, A2780V SP was found to be partially resistant to platinum. However, this resistance could not be explained by over-expression of the "excision repair cross-complementation group 1" (ERCC1) gene, which is essentially involved in the repair of platinated DNA damage. ERCC1 was, nonetheless, over-expressed in A2780V cells grown as spheres under stem cell-selective conditions as compared to adherent monolayers cultured under differentiating conditions. The same was true for the primary ovarian cancer cells B-57.In summary our investigations indicate that even in multi-passaged cancer cell lines hierarchic government of growth and differentiation is conserved and that the key cancer stem cell population may be composed of small overlapping cell fractions defined by various arbitrary markers.

Abstract
PURPOSE We assessed the value of contrast-enhanced US for differentiating between benign and malignant axillary lymph nodes in breast cancer. MATERIALS AND METHODS A total of 120 axillary lymph nodes in 92 patients with breast cancer were studied. All patients underwent grayscale US examination, unenhanced and enhanced color and power Doppler US, and enhanced grayscale harmonic US examination. RESULTS The mean size of the 120 axillary lymph nodes was 1.5 cm (range 0.5 - 3.4 cm). Of all 120 axillary lymph nodes studied, 80 (67 %) were malignant and 40 (33 %) were benign according to pathological examination. The total number of vessels in baseline US did not increase between benign and malignant lymph nodes (3.3 +/- 2.2 vs. 5.4 +/- 4.0; p > 0.05). The total number of peripheral vessels was 0.5 +/- 0.8 for benign lymph nodes vs. 2.0 +/- 1.7 for malignant lymph nodes (p > 0.05). Enhanced US studies showed enhancement in both benign and malignant lymph nodes after contrast administration with a significantly higher degree of enhancement in malignant lymph nodes (p < 0.01). The total number of vessels was significantly higher in malignant lymph nodes after contrast administration (17.3 +/- 8.0 vs. 8.2 +/- 5.1, p < 0.01). Malignant lymph nodes demonstrated longer contrast enhancement duration compared to benign lymph nodes. CONCLUSION This preliminary data shows that contrast-enhanced US can differentiate between benign and malignant lymph nodes in breast cancer.

Abstract
Similar to p73, the tumor suppressor gene p53 is subject to alternative splicing. Besides p53DeltaE6 and p53beta, we identified p53zeta, p53delta and p53varepsilon, arising from alternative splicing of exon 6 and intron 9, respectively. p53 splice variants were present in 18 of 34 ovarian cancer cell lines (52.9%) and 134 of 245 primary ovarian cancers (54.7%). p53delta expression was associated with impaired response to primary platinum-based chemotherapy (P=0.032). Also, p53delta expression constituted an independent prognostic marker for recurrence-free and overall survival (hazard ratio 1.854, 95% confidence interval 1.121-3.065, P=0.016; and hazard ratio 1.937, 95% confidence interval 1.177-3.186, P=0.009, respectively). p53beta expression was associated with adverse clinicopathologic markers, that is, serous and poorly differentiated cancers (P=0.002 and P=0.008, respectively), and correlated with worse recurrence-free survival in patients exhibiting functionally active p53 (P=0.049). DeltaN'p73 constituted the main N-terminally truncated p73 isoform and was preferentially found in ovarian cancer cell lines showing functionally active p53, supporting our hypothesis that N-terminally truncated p73 isoforms can alleviate the selection pressure for p53 mutations by the inhibition of p53 protein function.

Abstract
e16522 Background: Although, EGFR targeting has reached “bedside” in various tumor entities, including ovarian cancer, the essential role of E2F3a in EGFR mediated proliferation remained uncovered. Recently, we outlined the clinical relevance of E2F3a in ovarian cancer. Now we were able to elucidate the pathway between EGFR activation and E2F3a induction. Methods: Promoter mapping of E2F family members was assessed using the JASPER software. E2F3a protein was assessed by immunoblot analyses in siRNA based IRF-1, IRF-2 knockdown HOC-7 cells. Cell growth was determined by MTT assays after siRNA based knockdown of E2F3a. Expression of E2F3a regulating miR-34a, miR-210 and miR-20a were assessed by RT-PCR in 130 ovarian cancer patients and methylation status of the E2F3a promoter and of miRNA promoters were estimated using Methyllight. 6p22 amplification status of patients was determined by FISH analyses. Results: Promoter mapping of E2F family members revealed that IRF-1 and IRF-2 are potential intermediate components of the herein described EGFR-E2F3a axis. As evidenced by knock-down of IRF-1, IRF-2 or both, the ratio between the two mutually antagonistic IRF-1 and IRF-2 was found to be substantial for EGF induced E2F3a up-regulation. E2F3a knock-down yielded a complete abolishment of EGF induced cancer cell proliferation. Although, activated EGFR status showed a highly significant correlation with E2F3a expression, a subgroup of patients presented high E2F3a mRNA levels without EGFR activation. Within this subgroup promoter methylation of miRNA-34a, that regulates E2F3a, was revealed to represent an alternative mechanism of E2F3a regulation in ovarian cancer, whereas promoter methylation of E2F3a itself was not relevant in E2F3a control. Unlike in prostate or bladder cancer 6p22 amplification was not found to be relevant for E2F3a up-regulation in ovarian cancer. Conclusions: Our present data point to the substantial role of the ratio between IRF-1 and IRF-2 in EGFR mediated E2F3a induction. Furthermore, in vivo regulation of E2F3a involves methylation and thereby silencing of miR-34a. Targeting of the herein described molecular pathway, downstream EGFR, could represent an appealing therapeutic approach in ovarian cancer. No significant financial relationships to disclose.

Abstract
OBJECTIVE To report an uncommon case of a recurrent episode of primarily paraneoplastic dermatomyositis which was completely disconnected from the initially triggering malignancy and manifested as a silent pure multivisceral exacerbation. CASE A 70-year-old woman presented with a pure multivisceral episode of dermatomyositis without characteristic musculo-cutaneous symptoms one year after successful treatment of fallopian tube carcinoma with complete resolvement of a concomittant paraneoplastic dermatomyositis. The uncommon manifestation of recurrent dermatomyositis involving the lungs, spleen and liver, both adrenal glands and abdominal lymph nodes, mimicked a highly disseminated recurrence of the fallopian tube cancer. Physicians participating in the interdisciplinary tumor board were misled to opt for reinductive chemotherapy. Only histologic diagnosis obtained from multiple biopsies uncovered the inflammatory nature of the disease and spared the patient unneeded chemotherapy. CONCLUSION Asymptomatic multivisceral dermatomyositis may mimic metastatic spread of the initially underlying malignancy and may misdirect therapeutic strategies towards inadequate antineoplastic treatment.

Abstract
BACKGROUND A case of cervical cancer associated with irreducible procidentia successfully treated with external beam radiation and extracorporeal HDR-AL with concomitant chemotherapy followed by obliterative vaginal surgery is reported for the first time. CASE A 73-year-old woman presented in frail condition suffering from a huge, irreducible uterovaginal procidentia combined with a squamous cell carcinoma of the cervix in FIGO Stage IIa. Successful treatment consisted of sequential application of combined radiotherapy with concurrent cisplatin chemotherapy followed by total vaginal hysterectomy and partial colpectomy with colpocleisis according to the Labhardt method. The five-year follow-up documents the excellent long-term results with regard to cervical cancer and pelvic floor stability. CONCLUSION Especially in patients ineligible for extended surgery, radiochemotherapy followed by an obliterative surgical approach is feasible without aberrant wound healing and constitutes a suitable and efficient option for treating carcinomas of the cervix associated with irreducible genital prolapse.

Abstract
In cochlea inner hair cells (IHCs), L-type Ca(2+) channels (LTCCs) formed by alpha1D subunits (D-LTCCs) possess biophysical and pharmacological properties distinct from those of alpha1C containing C-LTCCs. We investigated to which extent these differences are determined by alpha1D itself by analyzing the biophysical and pharmacological properties of cloned human alpha1D splice variants in tsA-201 cells. Variant alpha1D(8A,) containing exon 8A sequence in repeat I, yielded alpha1D protein and L-type currents, whereas no intact protein and currents were observed after expression with exon 8B. In whole cell patch-clamp recordings (charge carrier 15-20 mm Ba(2+)), alpha1D(8A) - mediated currents activated at more negative voltages (activation threshold, -45.7 versus -31.5 mV, p < 0.05) and more rapidly (tau(act) for maximal inward currents 0.8 versus 2.3 ms; p < 0.05) than currents mediated by rabbit alpha1C. Inactivation during depolarizing pulses was slower than for alpha1C (current inactivation after 5-s depolarizations by 90 versus 99%, p < 0.05) but faster than for LTCCs in IHCs. The sensitivity for the dihydropyridine (DHP) L-type channel blocker isradipine was 8.5-fold lower than for alpha1C. Radioligand binding experiments revealed that this was not due to a lower affinity for the DHP binding pocket, suggesting that differences in the voltage-dependence of DHP block account for decreased sensitivity of D-LTCCs. Our experiments show that alpha1D(8A) subunits can form slowly inactivating LTCCs activating at more negative voltages than alpha1C. These properties should allow D-LTCCs to control physiological processes, such as diastolic depolarization in sinoatrial node cells, neurotransmitter release in IHCs and neuronal excitability.
