- In July 2012, as the four ground based gamma-ray telescopes of the H.E.S.S. (High Energy Stereoscopic System) array reached their tenth year of operation in Khomas Highlands, Namibia, a fifth telescope Look its first data as part of the system. This new Cherenkov detector, comprising a 614.5 m(2) reflector with a highly pixelized camera in its focal plane, improves the sensitivity of the current array by a factor two and extends ifs energy domain down to a few Lens of GeV. The present part l of the paper gives a detailed description of the fifth H.E.S.S. telescope's camera, presenting the details of both the hardware and the software, emphasizing the main improvements as compared to previous H.E.S.S. camera technology.

- Matrix metalloproteinases (MMPs) are group of enzymes thought to play an important role in trophoblastic and tumor invasion. The aim of our study was to investigate the trophoblastic expression of MMPs and p53 in normal trophoblast and hydatidiform moles (HM). Paraffin sections of 45 specimens, including 14 complete hydatidiform moles (CM), 15 partial hydatidiform moles (PM), 8 atypical partial hydatidiform moles (aPM), and 8 controls were selected. Classification of HM was established on histologic criteria and supported by the DNA ploidy results. Tissue sections from each case were immunostained with monoclonal antibodies, cytokeratin-7, MMP-2, MMP-9, tissue inhibitors of metalloproteinases (TIMP)-1, and p53 wild type (p53wt) and mutant types (mutp53). Staining for cytokeratin-7 revealed a positive reaction in 93% of the samples. MMP-2 was mainly expressed in the syncytiotrophoblast of HM and found in 62% of aPM, 60% PM, and 93% CM. The mutp53 was mainly and focally expressed in syncytiotrophoblastic cells and was found in 63% of aPM, 80% PM, and 93% CM. Expression of MMP-2 and mutp53 was both significantly greater in HM vs control group (P < 0.05) and greater in CM vs PM and aPM (P < 0.05). No significant difference was observed for cytokeratin-7, MMP-9, TIMP-1, and p53wt between the HM subgroups and between HM and control group. MMP-2 and mutp53 are overexpressed in HM as compared with normal trophoblast and might participate in the invasive behavior of the HM.

- AGO-OVAR 12 investigated the effect of adding the oral triple angiokinase inhibitor nintedanib to standard front-line chemotherapy for advanced ovarian cancer. At the primary analysis, nintedanib demonstrated significantly improved progression-free survival (PFS; primary endpoint) compared with placebo. We report final results, including overall survival (OS). Patients with primary debulked International Federation of Gynaecology and Obstetrics (FIGO) stage IIB–IV newly diagnosed ovarian cancer were randomised 2:1 to receive carboplatin (area under the curve 5 or 6) plus paclitaxel (175 mg/m2) on day 1 every 3 weeks for six cycles combined with either nintedanib 200 mg or placebo twice daily on days 2–21 every 3 weeks for up to 120 weeks. Between December 2009 and July 2011, 1,366 patients were randomised (911 to nintedanib, 455 to placebo). Disease was considered as high risk (FIGO stage III with amp;gt;1 cm residuum, or any stage IV) in 39%. At the final analysis, 605 patients (44%) had died. There was no difference in OS (hazard ratio 0.99, 95% confidence interval [CI] 0.83–1.17, p = 0.86; median 62.0 months with nintedanib vs. 62.8 months with placebo). Subgroup analyses according to stratification factors, clinical characteristics and risk status showed no OS difference between treatments. The previously reported PFS improvement seen with nintedanib did not translate into an OS benefit in the nonhigh-risk subgroup. Updated PFS results were consistent with the primary analysis (hazard ratio 0.86, 95% CI 0.75–0.98; p = 0.029) favouring nintedanib. The safety profile was consistent with previous reports. © 2019 UICC
