Abstract
The feasibility and surgical effort of a pre-lacrimal window approach (PLWA) depends on the width of the bony window anterior to the nasolacrimal duct. This study aimed to investigate gender-specific differences in feasibility of PLWA. A consecutive series of paranasal computed tomography scans from 50 females (n = 100) and 50 males (n = 100) were retrospectively analyzed. The primary outcome measure was the antero-posterior length of the bony pre-lacrimal window (BPLWA). The secondary outcome measure was the distribution of Simmen’s PLWA feasibility types (major, moderate and minor surgical effort). On average, males had a 1.5 mm (95% CI 0.8–2.2) significantly higher BPLW length in comparison to females [t(198) = 4.4, p < 0.0001]. The requirement of major surgical effort occurred 29% more frequently in females [χ2(1) = 17.7, p < 0.0001], whereas the necessity of moderate surgical effort was 21% more prevalent in males [χ2(1) = 8.8, p = 0.003]. The need of only minor surgical effort was twice as high in males compared to females [χ2(1) = 3, p = 0.081]. Our data indicates that females require more significant surgical effort during a PLWA to gain access to the maxillary sinus. These results are highly informative as a high amount of bone removal and nasolacrimal duct dislocation are associated with a higher likelihood of complications.

Abstract
Background: The objectives of this study were to evaluate the frequency of bony dehiscences in the optico-carotid recess (OCR) area and to measure the thickness of the bony lamellas bordering the OCR, according to our previously proposed OCR classification taking into account the extent of the recess. Methodology: A total of 100 human cadaver heads (n= 200 sphenoid sinuses) were investigated. Samples were divided into groups according to the presence and extent of OCR (no OCR, sub-optical OCR, latero-optical OCR). Bony dehiscences were visually identified and bone thickness was measured by using a high-resolution micrometer. Results: A bony dehiscence in the OCR area was observed in 20%. A significant difference in bony dehiscence occurrence rate between OCR types was found. The wall thickness of the bony carotid artery- and optic nerve canals bordering the OCR were 0.25 ± 0.16 mm and 0.27 ± 0.15 mm, respectively. Significant differences between OCR groups in bony wall thickness of the carotid artery canal and optic nerve canal were found. Samples with a latero-optical OCR had a significant thinner wall of the carotid artery and optic nerve canal than samples with a sub-optical OCR and no OCR. Conclusions: The current results indicate that the presence of an extended OCR, e.g. latero-optical, is highly associated with a greater risk of bony dehiscences and thinner bony lamellas in the OCR region.

Abstract
Pathologies located at the posterior surface of the anterior wall and the floor (alveolar recess) of the maxillary sinus are challen- ging to visualize and access. Open approaches including lateral rhinotomy, Caldwell-Luc procedure or midfacial degloving allow a broad visualization but with a significant likelihood of post-operative morbidity.

Abstract
Despite the high prevalence of chronic rhinosinusitis (CRS) and its impact on patients' quality of life, no European patient organization that advocates for patients with CRS currently exists. To fill this gap and give a voice to CRS patients, EUFOREA has created a patient advisory board, whose goal is to better understand the real-life needs of patients, to raise awareness at political level and to involve patients in the development of novel integrated solutions to accelerate access to accurate diagnosis and treatments. This report summarizes the key discussion points from the kick-off meeting of the board on the 8th June 2018 and provides an outline of the key objectives for the future.

Abstract
OBJECTIVES Reliable prognostic markers are lacking for tongue carcinoma. C-reactive protein (CRP) and a ratio from neutrophils/lymphocytes (NLR) are biomarkers, associated with prognosis in solid cancers. Aim of this work was to investigate the role of CRP and NLR in prognosis of patients with tongue carcinoma. DESIGN Retrospective cohort study. SETTING We retrospectively analysed data of patients treated for tongue carcinoma at our institution. Levels of CRP, Neutrophils and Lymphocytes were measured pretherapeutic. PARTICIPANTS 197 patients treated for squamous cell carcinoma of the tongue between 2002 and 2015. MAIN OUTCOME MEASURES Overall survival, disease-free survival. RESULTS Elevated CRP was significantly associated with shorter overall survival in our cohort in uni- and multivariate analysis. NLR was not associated with prognosis. CONCLUSION In the present study we could confirm the role of CRP as an independent prognostic marker in patients with tongue carcinoma. Incorporating this marker in prognostication could represent a valuable and moreover inexpensive tool for improved decisions making concerning therapy in the future.

Abstract
Nitric oxide (NO) has emerged as a signaling molecule in plants being involved in diverse physiological processes like germination, root growth, stomata closing and response to biotic and abiotic stress. S-nitrosoglutathione (GSNO) as a biological NO donor has a very important function in NO signaling since it can transfer its NO moiety to other proteins (trans-nitrosylation). Such trans-nitrosylation reactions are equilibrium reactions and depend on GSNO level. The breakdown of GSNO and thus the level of S-nitrosylated proteins are regulated by GSNO-reductase (GSNOR). In this way, this enzyme controls S-nitrosothiol levels and regulates NO signaling. Here we report that Arabidopsis thaliana GSNOR activity is reversibly inhibited by H2O2in vitro and by paraquat-induced oxidative stress in vivo. Light scattering analyses of reduced and oxidized recombinant GSNOR demonstrated that GSNOR proteins form dimers under both reducing and oxidizing conditions. Moreover, mass spectrometric analyses revealed that H2O2-treatment increased the amount of oxidative modifications on Zn2+-coordinating Cys47 and Cys177. Inhibition of GSNOR results in enhanced levels of S-nitrosothiols followed by accumulation of glutathione. Moreover, transcript levels of redox-regulated genes and activities of glutathione-dependent enzymes are increased in gsnor-ko plants, which may contribute to the enhanced resistance against oxidative stress. In sum, our results demonstrate that reactive oxygen species (ROS)-dependent inhibition of GSNOR is playing an important role in activation of anti-oxidative mechanisms to damping oxidative damage and imply a direct crosstalk between ROS- and NO-signaling.

Abstract
Despite the importance of superoxide dismutases (SODs) in the plant antioxidant defence system little is known about their regulation by post-translational modifications. Here, we investigated the in vitro effects of nitric oxide derivatives on the seven SOD isoforms of Arabidopsis thaliana. S-nitrosoglutathione, which causes S-nitrosylation of cysteine residues, did not influence SOD activities. By contrast, peroxynitrite inhibited the mitochondrial manganese SOD1 (MSD1), peroxisomal copper/zinc SOD3 (CSD3), and chloroplastic iron SOD3 (FSD3), but no other SODs. MSD1 was inhibited by up to 90% but CSD3 and FSD3 only by a maximum of 30%. Down-regulation of these SOD isoforms correlated with tyrosine (Tyr) nitration and both could be prevented by the peroxynitrite scavenger urate. Site-directed mutagenesis revealed that-amongst the 10 Tyr residues present in MSD1-Tyr63 was the main target responsible for nitration and inactivation of the enzyme. Tyr63 is located nearby the active centre at a distance of only 5.26 Å indicating that nitration could affect accessibility of the substrate binding pocket. The corresponding Tyr34 of human manganese SOD is also nitrated, suggesting that this might be an evolutionarily conserved mechanism for regulation of manganese SODs.

Abstract
The field of proteomics suffers from the immense complexity of even small proteomes and the enormous dynamic range of protein concentrations within a given sample. Most protein samples contain a few major proteins, which hamper in-depth proteomic analysis. In the human field, combinatorial hexapeptide ligand libraries (CPLL; such as ProteoMiner) have been used for reduction of the dynamic range of protein concentrations; however, this technique is not established in plant research. In this work, we present the application of CPLL to Arabidopsis (Arabidopsis thaliana) leaf proteins. One- and two-dimensional gel electrophoresis showed a decrease in high-abundance proteins and an enrichment of less abundant proteins in CPLL-treated samples. After optimization of the CPLL protocol, mass spectrometric analyses of leaf extracts led to the identification of 1,192 proteins in control samples and an additional 512 proteins after the application of CPLL. Upon leaf infection with virulent Pseudomonas syringae DC3000, CPLL beads were also used for investigating the bacterial infectome. In total, 312 bacterial proteins could be identified in infected Arabidopsis leaves. Furthermore, phloem exudates of pumpkin (Cucurbita maxima) were analyzed. CPLL prefractionation caused depletion of the major phloem proteins 1 and 2 and improved phloem proteomics, because 67 of 320 identified proteins were detectable only after CPLL treatment. In sum, our results demonstrate that CPLL beads are a time- and cost-effective tool for reducing major proteins, which often interfere with downstream analyses. The concomitant enrichment of less abundant proteins may facilitate a deeper insight into the plant proteome.
