Abstract
IKKβ plays a central role in the canonical NF-kB pathway, which has been extensively characterized. The role of IKKα in the noncanonical NF-kB pathway, and indeed in the canonical pathway as a complex with IKKβ, is less well understood. One major reason for this is the absence of chemical tools designed as selective inhibitors for IKKα over IKKβ. Herein, we report for the first time a series of novel, potent, and selective inhibitors of IKKα. We demonstrate effective target engagement and selectivity with IKKα in U2OS cells through inhibition of IKKα-driven p100 phosphorylation in the noncanonical NF-kB pathway without affecting IKKβ-dependent IKappa-Bα loss in the canonical pathway. These compounds represent the first chemical tools that can be used to further characterize the role of IKKα in cellular signaling, to dissect this from IKKβ and to validate it in its own right as a target in inflammatory diseases.

Abstract
Zenker's diverticulum occurs at the dorsal pharyngoesophageal junction through Killian's dehiscence and is caused by increased intrabolus pressure. Symptomatic disease most frequently affects male elderly patients. Primary symptom is oropharyngeal dysphagia, as well as regurgitation of undigested food, halitosis, and chronic aspiration. A barium swallow study is performed to confirm diagnosis. Treatment options for symptomatic patients include open surgery, as well as transoral rigid or flexible endoscopic procedures. Transoral procedures have become the main treatment approach over the past year thanks to reduced intraoperative complication rates compared to open surgery. The septum dividing the diverticulum from the esophagus is most commonly divided by a stapler device, papillotome, or laser. For high-risk patients who are poor candidates for general anesthesia, the procedure can be performed via flexible endoscopy in awake patients, albeit at an increased risk of recurrence.

Abstract
BACKGROUND AND PURPOSE 4D DSA allows acquisition of time-resolved 3D reconstructions of cerebral vessels by using C-arm conebeam CT systems. The aim of our study was to evaluate this new method by qualitative and quantitative means. MATERIALS AND METHODS 2D and 4D DSA datasets were acquired in patients presenting with AVMs, dural arteriovenous fistulas, and cerebral aneurysms. 4D DSA was compared with 2D DSA in a consensus reading of qualitative and quantitative parameters of AVMs (eg, location, feeder, associated aneurysms, nidus size, drainage, Martin-Spetzler Score), dural arteriovenous fistulas (eg, fistulous point, main feeder, diameter of the main feeder, drainage), and cerebral aneurysms (location, neck configuration, aneurysmal size). Identifiability of perforators and diameters of the injection vessel (ICA, vertebral artery) were analyzed in 2D and 4D DSA. Correlation coefficients and a paired t test were calculated for quantitative parameters. The effective patient dose of the 4D DSA protocol was evaluated with an anthropomorphic phantom. RESULTS In 26 patients, datasets were acquired successfully (AVM = 10, cerebral aneurysm = 10, dural arteriovenous fistula = 6). Qualitative and quantitative evaluations of 4D DSA in AVMs (nidus size: r = 0.99, P = .001), dural arteriovenous fistulas (diameter of the main feeder: r = 0.954, P = .03), and cerebral aneurysms (aneurysmal size: r = 1, P = .001) revealed nearly complete accordance with 2D DSA. Perforators were comparably visualized with 4D DSA. Measurement of the diameter of the injection vessel in 4D DSA was equivalent to that in 2D DSA (P = .039). The effective patient dose of 4D DSA was 1.2 mSv. CONCLUSIONS 4D DSA is feasible for imaging of AVMs, dural arteriovenous fistulas, and cerebral aneurysms. 4D DSA offers reliable visualization of the cerebral vasculature and may improve the understanding and treatment of AVMs and dural arteriovenous fistulas. The number of 2D DSA acquisitions required for an examination may be reduced through 4D DSA.

Abstract
Using optical in-situ measurements in an electrochemical environment, we study the electrochemical tuning of the transmission spectrum of films from the nanoporous gold (NPG) based optical metamaterial, including the effect of the ligament size. The long wavelength part of the transmission spectrum around 800 nm can be reversibly tuned via the applied electrode potential. The NPG behaves as diluted metal with its transition from dielectric to metallic response shifted to longer wavelengths. We find that the applied potential alters the charge carrier density to a comparable extent as in experiments on gold nanoparticles. However, compared to nanoparticles, a NPG optical metamaterial, due to its connected structure, shows a much stronger and more broadband change in optical transmission for the same change in charge carrier density. We were able to tune the transmission through an only 200 nm thin sample by 30%. In combination with an electrolyte the tunable NPG based optical metamaterial, which employs a very large surface-to-volume ratio is expected to play an important role in sensor applications, for photoelectrochemical water splitting into hydrogen and oxygen and for solar water purification.

Abstract
Aim of this retrospective analysis was to evaluate the survival times after percutaneous irreversible electroporation (IRE) in inoperable liver tumors not amenable to thermal ablation. 71 patients (14 females, 57 males, median age 63.5 ± 10.8 years) with 103 liver tumors were treated in 83 interventions using IRE (NanoKnife® system). The median tumor short-axis diameter was 1.9 cm (minimum 0.4 cm, maximum 4.5 cm). 35 patients had primary liver tumors and 36 patients had liver metastases. The Kaplan-Meier method was employed to calculate the survival rates, and the different groups were compared using multivariate log-rank and Wilcoxon tests. The overall median survival time was 26.3 months; the median survival of patients with primary land secondary liver cancer did not significantly differ (26.8 vs. 19.9 months; p = 0.41). Patients with a tumor diameter >3 cm (p < 0.001) or more than 2 lesions (p < 0.005) died significantly earlier than patients with smaller or fewer tumors. Patients with hepatocellular carcinoma and Child-Pugh class B or C cirrhosis died significantly earlier than patients with Child-Pugh class A (p < 0.05). Patients with very early stage HCC survived significantly longer than patients with early stage HCC with a median survival of 22.3 vs. 13.7 months (p < 0.05).

Abstract
OBJECTIVE To evaluate the efficacy of strain elastography (SE) using semi-quantitative measurement methods compared to constrast enhanced ultrasound during liver tumor surgery (Io-CEUS) for dignity assessment of focal liver lesions(FLL). MATERIAL AND METHODS Prospective data acquisition and retrospective analysis of US data of 100 patients (116 lesions) who underwent liver tumor surgery between 10/2010 and 03/2016. Retrospective reading of SE color patterns was performed establishing groups depending on dominant color (>50% blue = stiff, inhomogenous, >50% yellow/red/green = soft tissue). Semi-quantitative analysis was performed by Q-analysis based on a scale from 0 (soft) to 6 (stiff). 2 ROIs were placed centrally, 5 ROIs in the lesion's surrounding tissue. Io-CEUS was performed by bolus injection of 5-10 ml sulphurhexaflourid microbubbles evaluating wash-in- and -out- kinetics in arterial, portal venous and late phase. Histopathology after surgical resection served as goldstandard. RESULTS 100 patients (m: 65, f: 35, mean age 60.5 years) with 116 liver lesions were included. Lesion's size ranged from 0.5 to 8.4 cm (mean 2.42 cm SD±1.44 cm). Postoperative histology showed 105 malignant and 11 benign lesions. Semi-quantitative analysis showed central indurations of >2.5 in 76/105 cases suggesting malignancy. 7 benign lesions displayed no central indurations correctly characterized benign by SE. ROC-analysis and Youden index showed a sensitivity of 72.4% and specificity of 63.6% assuming a cut-off of 2.5. Io-CEUS correctly characterized 103/105 as malignant. Sensitivity was 98%, specificity 72.7%. CONCLUSION Strain elastography is a valuable tool for non-invasive characterization of FLLs. Semi-quantitative intratumoral stiffness values of >2.5 suggested malignancy. However, sensitivity of Io-CEUS in detecting malignant lesions was higher compared to SE. In conclusion SE should be considered for routine use during intraoperative US in addition to Io-CEUS for optimization of curative liver surgery.

Abstract
Zusammenfassung
Hintergrund Die Voraussetzungen für das langfristige Überleben einer perforierenden Keratoplastik sind im Säuglings- und Kindesalter aufgrund immunologischer Besonderheiten, der eingeschränkten Untersuchbarkeit sowie reduzierter Compliance und Therapieadhärenz à priori ungünstig. Jedoch stellt eine Hornhautübertragung oftmals die einzige Möglichkeit zur Prävention einer Amblyopie dar und ist somit alternativlos. Wir untersuchten das Indikationsspektrum, das Transplantatüberleben und das Komplikationsspektrum in einem bizentrischen Register aller Keratoplastiken im Kindesalter.
Material und Methoden Aus den elektronischen Transplantatregistern der beiden Zentren wurden alle Patienten recherchiert, die zum Zeitpunkt der jeweils 1. Keratoplastik das 18. Lebensjahr noch nicht vollendet hatten. Aus den Krankenakten wurden die Indikation, etwaiges Transplantatversagen, die Sehschärfe, Verlust des Augapfels und weitere Komplikationen systematisch recherchiert.
Ergebnisse Es wurden insgesamt 104 Augen von 95 Patienten (54 % weiblich) identifiziert. Das Durchschnittsalter bei der Operation betrug im Median 14 Jahre (Quartile 8 und 16 Jahre). Die Nachbeobachtungszeit lag im Median bei 2,7 Jahren. Es zeigten sich folgende Indikationen: Keratokonus (39 %), perforierende Verletzung (18 %), nicht herpetische Hornhautnarben (12 %), herpetische Hornhautnarben (6 %), Sklerokornea (3 %), Verätzung (3 %) und die heterogene Gruppe der sonstigen Indikationen (19 %). Das nach Kaplan-Meier geschätzte klare Transplantatüberleben reichte zum Zeitpunkt der Durchschnittsnachbeobachtungszeit von 100 % (Keratokonus) bis 35 % (Sklerokornea). Ein Verlust des Augapfels war ausschließlich nach perforierender Verletzung (n = 2) zu verzeichnen. Nach 1 Jahr sind in der Kaplan-Meier-Schätzung alle Transplantate in der Gruppe der Säuglinge eingetrübt. In der Gruppe der Kleinkinder bis Jugendlichen sind 90 % der Transplantate zu diesem Zeitpunkt noch klar.
Schlussfolgerungen Die Prognose der Keratoplastik im Kindesalter hängt sowohl von der initialen Indikation und damit indirekt von der Grunderkrankung als auch vom Alter ab. Eine besonders schlechte Prognose zeigte die Gruppe der Säuglinge mit einem nur sehr kurzen Transplantatüberleben. Bei den Indikationen zeigte die Gruppe der Kinder mit Keratokonus die besten Ergebnisse. Als prognostisch ungünstig erwiesen sich Sklerokornea sowie perforierende Augenverletzungen.

Abstract
BACKGROUND AND PURPOSE Endovascular flow diverters are increasingly used for the treatment of cerebral aneurysms. We assessed the safety and efficacy of the Flow-Redirection Endoluminal Device (FRED) in a consecutive series of 50 patients. MATERIALS AND METHODS Inclusion criteria were wide-neck, blister-like, or fusiform/dissecting aneurysms independent of size, treated with the FRED between February 2014 and May 2015. Assessment criteria were aneurysm occlusion, manifest ischemic stroke, bleeding, or death. The occlusion rate was assessed at 3 months with flat panel CT and at 6 months with DSA by using the Raymond classification and the O'Kelly-Marotta grading scale. RESULTS Fifty patients with 52 aneurysms were treated with 54 FREDs; 20 patients were treated with the FRED and coils. Aneurysm size ranged from 2.0 to 18.5 mm. Deployment of the FRED was successful in all cases. There were no device-associated complications. One patient developed mild stroke symptoms that fully receded within days. There have been no late-term complications so far and no treatment-related mortality. Initial follow-up at 3 months showed complete occlusion in 72.3% of the overall study group, Six-month follow-up showed total and remnant-neck occlusion in 87.2% of patients, distributed over 81.5% of the FRED-only cases and 95.0% of the cases with combined treatment. CONCLUSIONS The FRED flow diverter is a safe device for the treatment of cerebral aneurysms of various types. Our data reveal high occlusion rates at 3 and 6 months, comparable with those in other flow diverters. Long-term occlusion rates are expected.

Abstract
In this chapter, we discuss implications of tumor site and tumor microenvironment properties of human papilloma virus (HPV)-associated cancer formation with special emphasis on the therapeutic modality of transoral robotic surgery (TORS). Over the past years, the development of robotic systems has improved, and therefore, its use in the surgical treatment of HNSCC has become a relevant treatment modality for many patients. Yet, there are limitations. Especially for endolaryngeal TORS procedures, additional technical development is mandatory, particularly with respect to visualization and manipulation. The Flex System has provided new additions that need to be further evaluated. TORS systems are going to improve technical issues and therefore reduce patient morbidity, surgical handling and treatment costs. The developed systems have to be tested and evaluated in prospective trials in order to be able to identify benefits and disadvantages in patient care. With respect to HPV-related OPSCC, TORS has become a valuable surgical alternative for an increasing number of patients.

Abstract
INTRODUCTION Adamantinoma (AD) is an ultimately rare, low-grade malignant bone tumor. In most cases it occurs in the tibia of young adults. Osteofibrous dysplasia (OFD) is a rare, benign, lesion that is typically seen in children. Histopathology, ultrastructure, and cytogenetics indicate that these lesions are closely related. Yet, etiology remains a matter of debate. Local recurrence rates are high for both entities as published in literature and long-term outcomes are scarce, due to the rarity of the disease. HYPOTHESIS AD should be treated by En-Bloc resection while ODF can be treated by curettage or by observation. Consequently, the aim of the present study was to answer following questions: Were local recurrence rates of both entities different based on a retrospective review within a tertiary referral center for orthopedic oncology? MATERIAL AND METHODS In a retrospective cohort study, 10 patients with AD and 5 patients with OFD (including 1 patient with OFD-like-AD) were reviewed. Primary surgeries for patients with AD were: En-bloc resection in 7, curettage in 2 and amputation in 1. In the OFD group, only 2 patients underwent surgery by curettage. Mean follow-up was 16 years (range: 2-47 years). Nine patients had a minimum follow-up of 10 years (mean: 23 years; range: 10-47 years). RESULTS Four patients with AD (40%) and 2 patients with OFD (40%) - all of them following surgical removal - suffered from local recurrence. In the "En bloc" resection group of AD, there were 2 LR (29%). All patients of both groups treated with curettage showed LR. One patient with AD had metastasis at time of diagnosis and died of disease. Another patient with AD was diagnosed with metastasis 67 months after surgery and was still alive with disease at latest follow-up (77 month). DISCUSSION The overall prognosis of AD and OFD is good, yet local recurrence rates are high, irrespective of surgical strategy. While an internationally standardized treatment regime is still missing, a more radical surgical approach should be considered, especially when treating AD. LEVEL OF EVIDENCE Retrospective study; Level IV.

Abstract
Hulecoeteomyia japonica japonica (= Aedes japonicus japonicus) (Diptera: Culicidae) (Theobald 1901), a container-breeding invasive species in North America and Europe, is attracting particular attention for its high local abundances and possible roles in the transmission of human and animal pathogens. The preferential habitats of this species are forested and bushy areas, which renders control measures extremely inefficient. Use of the sterile insect technique (SIT) may contribute to the implementation of area-wide integrated pest management strategies, as has been successfully proven with other aedine mosquito species. The present study investigates the effects of irradiation at a dose of 40 Gy on fitness parameters in H. j. japonica. Irradiation was performed on 16-24-h-old pupae from a colonized strain (PA) using a TrueBeam linear accelerator. Males from the PA strain were crossed with females of the same colony or with field-collected females. Irradiation induced a slight increase in mortality in male pupae, but did not alter the survival and mating abilities of emerging adult males. Rates of blood feeding and fertility were lower when PA strain males were kept with field-collected females rather than PA females. Irradiated males induced reductions in fertility (residual fertility: 2.6%) and fecundity in mated females. The data indicate that the SIT is a suitable technique to enhance the control of this species.
