Abstract
INTRODUCTION Hypoxia-induced autophagy leads to an increase in vasculogenic-mimicry (VM) and the development of resistance of glioblastoma-cells to bevacizumab (BEV). Chloroquine (HCQ) inhibits autophagy, reduces VM and can thus produce a synergistic effect in anti-angiogenic-therapy by delaying the development of resistance to BEV. PURPOSE We retrospectively compared the combined addition of HCQ+BEV and adjuvant-radiochemotherapy (aRCT) to aRCT alone for recurrent-glioblastoma (rGBM) in regards of overall survival (OS). METHODS Between 2006 and 2016, 134 patients underwent neurosurgery for rGBM at our institution. Forty-two patients (Karnofsky-Performance-Score>60%) with primary-glioblastoma underwent repeat-surgery and aRCT for recurrence. Four patients (9.5%) received aRCT+HCQ+BEV. Five patients received aRCT+BEV. RESULTS In rGBM-patients who were treated with aRCT+HCQ+BEV, median OS was 36.57 months and median post-recurrence-survival (PRS) was 23.92 months while median PRS in the control-group was 9.63 months (p=0.022). In patients who received aRCT+BEV, OS and PRS were 26.83 and 12.97 months, respectively. CONCLUSIONS Although this study was performed on a small number of highly selected patients, it demonstrates a synergistic effect of HCQ+BEV in the treatment of rGBM which previously could be demonstrated based on experimental data. A significant increase of OS in patients who receive aRCT+HCQ+BEV cannot be ruled out and should be further investigated in randomised-controlled-trials.

Abstract
We demonstrate high-repetition-rate imaging of the liquid-film thickness in the 50-1000 µm range resulting from impinging water droplets on a glass surface. The pixel-by-pixel ratio of line-of-sight absorption at two time-multiplexed near-infrared wavelengths at 1440 and 1353 nm was detected with a high-frame-rate InGaAs focal-plane array camera. Frame rates of 1 kHz and thus measurement rates of 500 Hz could be achieved, well suited to capture the fast dynamics of droplet impingement and film formation. The droplets were sprayed onto the glass surface using an atomizer. Suitable absorption wavelength bands for water droplet/film imaging were determined from Fourier-transform infrared (FTIR) spectra of pure water between 298 and 338 K. At 1440 nm, the water absorption is nearly temperature-independent, making the measurements robust against temperature fluctuations. Time-resolved imaging measurements capturing the dynamics of the water droplet impingement and evolution were successfully demonstrated.

Introduction
Human induced pluripotent stem cell-derived cardiomyocytes (HiPSC-CM) are an emerging, powerful tool to study human cardiac physiology, pharmacology and toxicology, to model cardiovascular diseases or even to use for cardiac repair. Understanding the similarities and differences between hiPSC-CM and adult human cardiomyocytes is critical for their use. Here we focus on sodium calcium exchanger (NCX) who plays a crucial role in the Ca2+-homeostasis in the mammalian heart. Importantly, alterations in NCX expression in human heart are associated with various cardiac pathologies such as heart failure or arrhythmias. In order to investigate whether hiPSC-CM could serve as model for adult human heart NCX we measured the properties of NCX in hiPSC-CM and human ventricular tissue. Rat ventricular tissue was used for comparison.
Methods
HiPSC-CM were differentiated from a healthy iPSC line and dissociated from engineered heart tissue (EHT). Adult human and rat cardiomyocytes were digested from ventricular samples. We measured NCX current by the whole-cell patch clamp technique at 37 °C. Standard sharp microelectrodes were used to record action potentials (AP). Contractile force in human and rat ventricular samples was measured isometrically. A video-optical contractility test system was used to measure force in EHT. SEA0400 (10 µM) was used to block NCX.
Results
NCX currents could be measured in every hiPSC-CM. The NCX current densities in hiPSC-CM were larger than in human ventricular cardiomyocytes (3.2±0.2 pA/pF n=28 vs. 1.3±0.2 pA/pF n=15, p<0.05), but lower than reported for rat left ventricular cardiomyocytes using the same protocol. SEA0400 shortened APD90 markedly in EHT (264.1±24.9 ms to 191±31.6 ms, n=4) and to a lesser extent in rat ventricular tissue (54.4±3.9 ms to 48.9±4.2 ms, n=7). Shortening in human left ventricular preparations was tiny (320±22.1 ms to 305.5±20.3 ms, n=6) and not different from time-matched controls (TMC). Resting membrane potential, action potential amplitude and upstroke velocity were not affected neither in EHT nor in left ventricular preparations (rat and human). Force was significantly increased by NCX block in rat ventricle (by 31±5.4%, n=18) and EHT (by 20.8±3.9%, n=4), but in human left ventricular preparations there was only a tendency to attenuate spontaneous run-down (-3.7±4.3% n=8 with SEA vs. -6.2±3.7% n=12 in TMC).
Conclusion
HiPSC-CM possess NCX in the physiological range. HiPSC-CM show NCX-effects on APD and force as predicted from rat ventricle and in full accordance with cardiac physiology. Lack of NCX effect in human adult ventricles that had been already reported previously needs further investigations.

Abstract
We present a method to simultaneously measure the film thickness and individual concentrations of two urea derivates (urea CH4N2O and dimethylurea C3H8N2O) mixed in an aqueous solution at constant temperature using near-infrared (NIR) absorption at multiple specific wavelengths. Fourier transform infrared (FTIR) spectra of aqueous mixtures of urea and dimethylurea solutions were recorded in the 1250-2500 nm wavelength range in thin-layer quartz cuvettes at room temperature. The spectra reveal suitable detection wavelengths, i.e., 1450, 1933, 2200, and 2270 nm, for which both the absorption coefficient and its variation with the species concentration are large enough to achieve satisfactory detection sensitivity and selectivity. For validation measurements, samples were prepared in thin-layer quartz transmission cells with known path lengths and mixture compositions in the range 100-1000 µm and 0-40 wt.%, respectively. Film thickness and mass fractions of both species were determined from measured absorbance ratios in the determined characteristic wavelength bands.

Abstract
We investigate the electronic structure of Cs2CuCl4, a material discussed in the framework of a frustrated quantum antiferromagnet, by means of resonant inelastic x-ray scattering (RIXS) and density functional theory (DFT). From the non-dispersive highly localizedddexcitations, we resolve the crystal field splitting of the Cu2+ions in a strongly distorted tetrahedral coordination. This allows us to model the RIXS spectrum within the crystal field theory (CFT), assign theddorbital excitations and retrieve experimentally the values of the crystal field splitting parametersDq,DsandDτ. The electronic structure obtainedab-initioagrees with the RIXS spectrum and modelled by CFT, highlighting the potential of combined spectroscopic, cluster and DFT calculations to determine the electronic ground state of complex materials.

Abstract
UNLABELLED Knowledge about risk factors of mortality after hip fracture might encourage prevention and further improvements in care. This study identified patient risk factors as well as hospital and regional characteristics associated with a decreased risk. Variation of mortality was largest on patient level and modest on hospital and regional level. INTRODUCTION Among numerous studies analyzing mortality as worst consequence after hip fracture, the majority focused on patient level and fewer on hospital and regional level. Comprehensive knowledge about contributing factors on all levels might help to reveal relevant inequalities, which would encourage prevention and further improvements in care. This study aimed at investigating variation of mortality after hip fracture on patient, hospital, and regional level in Germany. METHODS We performed a retrospective cohort study on hip fracture patients aged 65 and older using statutory health insurance claims data from Jan 2009 through Dec. 2012 and additional information from the Federal Statistical Office Germany. Regions were classified based on two-digit postal code. We applied a multilevel Cox proportional hazard model with random intercepts on hospital and regional level to investigate the risk factors for mortality within 6 and 12 months after hip fracture. RESULTS The dataset contained information on 123,119 hip fracture patients in 1014 hospitals in 95 German regions. Within 6/12 months, 20.9%/27.6% of the patients died. On patient level, male sex, increasing age, increased pre-fracture care level, and increasing comorbidity were associated with an increased hazard of mortality. Hospitals with increasing hip fracture volume or with orthogeriatric co-management and regions with increased population density were associated with a decreased hazard. Variation was largest on patient level and rather modest on hospital and regional level. CONCLUSIONS The identification of patient-related risk factors enables prognosticating mortality after hip fracture. After adjusting for those, variation seemed to be attributable rather to hospitals than to regions.

Abstract
Pilot testing of direct potable reuse (DPR) using multi-stage ozone and biological filtration as an alternative treatment train without reverse osmosis (RO) was investigated. This study examined four blending ratios of advanced treated reclaimed water from the F. Wayne Hill Water Resources Center (FWH WRC) in Gwinnett County, Georgia, combined with the existing drinking water treatment plant raw water supply, Lake Lanier, for potable water production. Baseline testing with 100 percent (%) Lake Lanier water was initially conducted; followed by testing blends of 15, 25, 50, and 100% reclaimed water from FWH WRC. Finished water quality from the DPR pilot was compared to drinking water standards, and emerging microbial and chemical contaminants were also evaluated. Results were benchmarked against a parallel indirect potable reuse (IPR) pilot receiving 100% of the raw water from Lake Lanier. Finished water quality from the DPR pilot at the 15% blend complied with the United States primary and secondary maximum contaminant levels (MCLs and SMCLs, respectively). However, exceedances of one or more MCLs or SMCLs were observed at higher blends. Importantly, reclaimed water from FWH WRC was of equal or better quality for all microbiological targets tested compared to Lake Lanier, indicating that a DPR scenario could lower acute risks from microbial pathogens compared to current practices. Finished water from the DPR pilot had no detections of microorganisms, even at the 100% FWH WRC effluent blend. Microbiological targets tested included heterotrophic plate counts, total and fecal coliforms, Escherichia coli, somatic and male-specific coliphage, Clostridium perfringens, Enterococci, Legionella, Cryptosporidium, and Giardia. There were water quality challenges, primarily associated with nitrate originating from incomplete denitrification and bromate formation from ozonation at the FWH WRC. These challenges highlight the importance of upstream process monitoring and control at the advanced wastewater treatment facility if DPR is considered. This research demonstrated that ozone with biological filtration could achieve potable water quality criteria, without the use of RO, in cases where nitrate is below the MCL of 10 mg nitrogen per liter and total dissolved solids are below the SMCL of 500 mg per liter.

Abstract
We report the case of a 28-year-old female patient who complained of extreme neck pain when giving birth to a child. Magnetic resonance imaging (MRI) of the cervical spine demonstrated an osteolytic lesion at the second cervical vertebral body (C2). In this presentation, we highlight a transoral surgical approach in order to prevent instability of this osteolytic lesion. To the best of our knowledge, this is the first time that such a route of access has been described for this tumor entity. A histopathologic examination led to the diagnosis of epithelioid hemangioendothelioma. During a follow-up period of 33 months, the patient had no complaints.

Abstract
Abstract
Background
Macrophages are the most abundant immune cells in the myocardial tissue in steady state. The sterile inflammation caused by myocardial infarction triggers a massive immune reaction, which leads to a profound influx of neutrophils and monocytes. In the postacute phase of infarction macrophages play an essential role in reparative processes. Recently, it has become clear that macrophages in the heart have a dual developmental origin from embryonic and bone marrow (BM) hematopoiesis. In this study, we sought to investigate the contribution of embryonic derived macrophages to the cardiac macrophage pool in steady state as well as the acute and chronic phase after ischemia/reperfusion injury.
Methods/Results
To address the origin of macrophages in steady state we used different models of lineage tracing to determine the developmental origin of cardiac macrophages. Using FLT3-Cre mice and radiation-independent CD45.1/.2 bone marrow chimera, we found that the resident macrophage population in the heart is mainly independent of definitive hematopoiesis (approximately 70–80% of cardiac macrophages). The BM-dependent population on the other hand is replenished by blood-derived monocytes.
Further we used the radiation-independent CD45.1/.2 bone marrow chimera to characterize the origin of macrophages at different time points after I/R-injury. In the acute phase after myocardial infarction we observed a profound influx of BM-derived macrophages in the infarct region and also in the remote area. 30 days after I/R-injury the composition of the resident macrophage pool was mainly comprised of BM-independent macrophages, similar to steady state conditions. To address the role of BM-derived macrophages we used CCR2-ko mice, which have low numbers of inflammatory monocytes in peripheral blood. CCR2-ko mice showed reduced macrophage numbers in the acute phase after myocardial infarction. Using positron emission tomography we investigated the influence of CCR2-deficiency on cardiac function after I/R-injury. In comparison to WT mice, CCR2-ko mice showed a significantly increased infarct size. Cardiac remodeling, determined by end-diastolic volume, on the other hand was improved in CCR2-ko mice. The ejection fraction was similar in both groups.
Conclusion
The cardiac macrophage pool is mainly comprised of BM-independent macrophages. In response to I/R-injury monocyte-derived macrophages transiently enter the myocardium but do not persist in significant numbers over time. The influx of BM-derived macrophages after I/R-injury was reduced using CCR2-ko mice, which led to improved cardiac remodeling.
Our findings are of potential importance for understanding the cardiac immune response and for the therapeutic targeting of macrophages in inflammatory conditions.

Abstract
CLINICAL/METHODICAL ISSUE Diagnostic imaging plays a crucial role in the assessment and stratification of pathologic conditions causing acute abdomen. This report provides information on etiology, clinical manifestations and therapeutic options for six common diseases resulting in acute abdomen-appendicitis, cholecystitis, bowel obstruction, diverticulitis, acute pancreatitis, and viscus perforation. PERFORMANCE Besides initial ultrasound, CT scans often represent the imaging gold standard for the diagnostic evaluation of acute abdomen. PRACTICAL RECOMMENDATIONS Depending on the underlying pathologic condition, sonography or CT is suitable for the stratification of the gastrointestinal disease causing acute abdomen.

Abstract
In many scientific communities, the definition of standardized experiments has enabled major progress in process understanding. The investigation of the spray-flame synthesis of nanoparticles at a well-defined standard burner by experiment and simulation makes it possible to produce a comprehensive data set with various established and novel measuring methods. In this work, we introduce the design of the SpraySyn burner as a new standard for a free-jet type burner that offers well-defined and simulation-friendly boundary conditions and geometries as well as accessibility for optical diagnostics. A combustible precursor solution is fed through a centrally located capillary and aerosolized with an oxygen dispersion gas flow. The spray flame is stabilized by a premixed flat methane/oxygen pilot flame fed via a porous bronze matrix surrounded by a stabilizing nitrogen coflow emanating through the same porous matrix, providing easy-to-calculate boundary conditions for simulations. This burner design enables the use of a wide choice of solvents, precursors, and precursor combinations. Best-practice operating instructions and parameters are given, and large-eddy simulations are performed demonstrating the suitability of the SpraySyn burner for computational fluid dynamics simulations. For ensuring reproducible operation across labs, we define a consumer-camera-based flame characterization scheme for the quantitative assessment of the flame geometry such as flame length, diameter, tilt angle, and photometric distribution of visible chemiluminescence along the center axis. These parameters can be used for benchmarking the pilot and spray flame by each user of the SpraySyn burner with the reference flames.

Abstract
We demonstrate a multi-wavelength near-infrared (NIR) broadband absorption sensor for the simultaneous monitoring of layer thickness and urea concentration of aqueous urea solutions. Samples were prepared in thin-layer quartz transmission cells. Film thickness and urea mass fraction (at constant temperature) were determined from measured transmittance ratios in characteristic wavelength bands selected by narrowband filters in front of the detector and converted to absorbance ratios. Suitable emission bands were selected depending on the sensitivity of the NIR absorption spectrum of the solution with respect to temperature and solute concentration. For this purpose, Fourier transform IR spectra of aqueous urea solutions were recorded in the 1250-2500 nm wavelength range for urea concentrations between 0 and 40 wt.% and temperatures between 298 K and 338 K. A prototype sensor was designed using a continuous-wave fiber-coupled incoherent tungsten lamp, subsequent intensity modulation, and lock-in detection of the transmitted radiation. The sensor concept was validated with measurements using a calibration cell providing liquid layers of variable thicknesses (7-1000 μm).

Abstract
OBJECTIVESince 2007, a continuous neurosurgery emergency service has been available in the International Security Assistance Force (ISAF) field hospital in Mazar-e-Sharif (MeS), Afghanistan. The object of this study was to assess the number and range of surgical procedures performed on the spine in the period from 2007 to 2014.METHODSThis is a retrospective analysis of the annual neurosurgical caseload statistics from July 2007 to October 2014 (92 months). The distribution of surgical urgency (emergency, delayed urgency, or elective), patient origin (ISAF, Afghan National Army, or civilian population), and underlying causes of diseases and injuries (penetrating injury, blunt injury/fracture, or degenerative disease) was analyzed. The range and pattern of diagnoses in the neurosurgical outpatient department from 2012 and 2013 were also evaluated.RESULTSA total of 341 patients underwent neurosurgical operations in the period from July 2007 to October 2014. One hundred eighty-eight (55.1%) of the 341 procedures were performed on the spine, and the majority of these surgeries were performed for degenerative diseases (127/188; 67.6%). The proportion of spinal fractures and penetrating injuries (61/188; 32.4%) increased over the study period. These spinal trauma diagnoses accounted for 80% of the cases in which patients had to undergo operations within 12 hours of presentation (n = 70 cases). Spinal surgeries were performed as an emergency in 19.8% of cases, whereas 17.3% of surgeries had delayed urgency and 62.9% were elective procedures. Of the 1026 outpatient consultations documented, 82% were related to spinal issues.CONCLUSIONSCompared to the published numbers of cases from neurosurgery units in the rest of the ISAF area, the field hospital in MeS had a considerably lower number of operations. In addition, MeS had the highest rates of both elective neurosurgical operations and Afghan civilian patients. In comparison with the field hospital in MeS, none of the other ISAF field hospitals showed such a strong concentration of degenerative spinal conditions in their surgical spectrum. Nevertheless, the changing pattern of spine-related diagnoses and surgical therapies in the current conflict represents a challenge for future training and material planning in comparable missions.

Abstract
Tyrosine kinase inhibitors (TKIs) of the epidermal growth factor receptor (EGFR) are widely used in non-small cell lung cancer patients harboring activating EGFR mutations. However, resistance mechanisms, particularly the T790 M mutation, hamper longer-term therapeutic success of first and second generation EGFR-TKIs. To address this unmet medical need, EGFR-TKIs of the third generation are under clinical development. Relevant clinical efficacy with mainly mild to moderate class-specific side effects has been shown for third-generation EGFR-TKIs. Molecular testing is of major importance in deciding for treatment with third generation EGFR-TKIs. This article elucidates the developmental state of third generation EGFR-TKIs with its focus on Osimertinib, the first and currently the only compound in this class which is approved in Germany. Additionally, the medical importance of molecular diagnosis using tumor tissue and circulating tumor DNA is discussed.

Abstract
Autoignition of fuel/air mixtures is a determining process in internal combustion engines. Ignition can start either homogeneously in the gas phase after compression or in the vicinity of hot surfaces. While ignition properties of commercial fuels are conventionally described by a single quantity (octane number), it is known that some fuels have a varying propensity to the two processes. We present a new experimental concept that generates well-controlled temperature inhomogeneities in the shock-heated gases of a high-pressure shock tube. A shock-heated reactive mixture is brought into contact with a heated silicon nitride ceramic glow plug. The glow-plug temperature can be set up to 1200 K, higher than the post-reflected-shock gas temperatures (650-1050 K). High-repetition-rate chemiluminescence imaging is used to localize the onset of ignition in the vicinity of the hot surface. In experiments with ethanol, the results show that in most cases under shock-heated conditions, the ignition begins inhomogeneously in the vicinity of the glow plug and is favored because of the high wall temperature. Additionally, the interaction of geometry, external heating, and gas-dynamic effects was investigated by numerical simulations of the shock wave in a non-reactive flow.

Abstract
Abstract
Background: As an alternative option to ADMs (acellular dermal matrices) synthetic meshes are a cheaper and equally effective option in implanted breast reconstruction. However, clinical data concerning these synthetic meshes is limited. Also, direct comparisons between titanium-coated polypropylene mesh (TiLoop Bra/TiMesh) and partially absorbable polypropylene mesh (Seragyn) have not yet been reported. Therefore, this work will report clinical complication rate data on 320 cases of synthetic meshes TiLoop Bra/TiMesh and Seragyn.
Methods: This analysis represents a retrospective single surgeon multi-center study of 320 cases over 14 years (2003 until 2016) using either TiLoop Bra/TiMesh (n=192) or Seragyn (n=128) in breast reconstruction. Patient recruitment was consecutive. 124 cases of the TiLoop Bra /TiMesh cohort and 74 cases in the Seragyn cohort were oncological interventions. Results were correlated with ADM based reconstructions (Epiflex and SurgiMend) performed by the same surgeon.
Results: Major complication rates (i.e. revision surgery) occurred in 3.9 % (Seragyn) and 8.3 % (TiLoop Bra/TiMesh) of all cases. (not statistically significant). Minor complications (i.e. seroma requiring aspiration, infection requiring antibiotics, red breast syndrome/rash (RBS) and wound dehiscence occurred in 18 % (Seragyn) and 8.9 % (TiLoop Bra/TiMesh). Overall minor complication rates did also not differ statistically significant. However, subgroup analysis showed RBS to occur more often in the Seragyn group (3.9 % Seragyn vs. 0.5 % TiLoop Bra/TiMesh, p<0.05). A significant difference between SurgiMend and Epiflex compared to the synthetic meshes could also not been shown.
Conclusion: This retrospective analysis shows that titanium-coated polypropylene meshes like TiLoop Bra/TiMesh and partially absorbable meshes like Seragyn do not differ significantly in complication rates. Compared to the exponentially more expensive ADM alternatives complication rates did also not differ significantly. Synthetic meshes seem to be a cheaper and equally effective option.

Abstract
Bluetongue virus (BTV) hitherto consisted of 26 recognized serotypes, of which all except BTV-26 are primarily transmitted by certain species of Culicoides biting midges. Three variants of an additional 27th bluetongue virus serotype (BTV-27v01-v03) were recently detected in asymptomatic goats in Corsica, France, 2014-2015. Molecular characterization revealed genetic differences between the three variants. Therefore, in vivo characteristics were investigated by experimental infection of a total of 15 goats, 11 sheep and 4 cattle with any one of the three variants in separated animal trials. In goat trials, BTV-naïve animals of the same species were kept in a facility where direct contact was unhindered. Of the 15 inoculated goats, 13 and 14 animals were found positive for BTV-RNA and antibodies (Ab), respectively, until the end of the experiments. Surprisingly, BTV-Ab levels as measured with ELISA and neutralization test (SNT) were remarkably low in all seropositive goats. Virus isolation from whole-blood was possible at the peak of viremia until 49 dpi. Moreover, detection of BTV-27v02-RNA and Ab in one contact goat indicated that-similar to BTV-26-at least one of three BTV-27 variants may be transmitted by contact between goats. In the field, BTV-27 RNA can be detected up to 6 months in the whole-blood of BTV-27-infected Corsican goats. In contrast, BTV RNA was not detected in the blood of cattle or sheep. In addition, BTV-27 Abs were not detected in cattle and only a transient increase in Ab levels was observed in some sheep. None of the 30 animals showed obvious BT-like clinical signs. In summary, the phenotypes observed for BTV-27v01-v03 phenotypes correspond to a mixture of characteristics known for BTV-25 and 26.

Abstract
BACKGROUND The European Organization for Research and Treatment of Cancer (EORTC) QLQ-LC13 was the first module to be used in conjunction with the core questionnaire, the QLQ-C30. Since the publication of the LC13 in 1994, major advances have occurred in the treatment of lung cancer. Given this, an update of the EORTC QLQ-LC13 was undertaken. METHODS The study followed phases I to III of the EORTC Module Development Guidelines. Phase I generated relevant quality-of-life issues using a mix of sources including the involvement of 108 lung cancer patients. Phase II transformed issues into questionnaire items. In an international multicenter study (phase III), patients completed both the EORTC QLQ-C30 and the 48-item provisional lung cancer module generated in phases I and II. Patients rated each of the items regarding relevance, comprehensibility, and acceptance. Patient ratings were assessed against a set of prespecified statistical criteria. Descriptive statistics and basic psychometric analyses were carried out. RESULTS The phase III study enrolled 200 patients with histologically confirmed lung cancer from 12 centers in nine countries (Cyprus, Germany, Italy, Israel, Spain, Norway, Poland, Taiwan, and the UK). Mean age was 64 years (39 - 91), 59% of the patients were male, 82% had non-small-cell lung cancer, and 56% were treated with palliative intent. Twenty-nine of the 48 questions met the criteria for inclusion. CONCLUSIONS The resulting module with 29 questions, thus currently named EORTC QLQ-LC29, retained 12 of the 13 original items, supplemented with 17 items that primarily assess treatment side-effects of traditional and newer therapies.

Abstract
Shock tubes allow for the study of ultra-fast gas-phase reactions on the microsecond time scale. Because the repetition rate of the experiments is low, it is crucial to gain as much information as possible from each individual measurement. While reaction-time-resolved species concentration and temperature measurements with fast absorption methods are established, conventional laser-induced fluorescence (LIF) measurements with pulsed lasers provide data only at a single reaction time. Therefore, fluorescence methods have rarely been used in shock-tube diagnostics. In this paper, a novel experimental concept is presented that allows reaction-time-resolved LIF measurements with one single laser pulse using a test section that is equipped with several optical ports. After the passage of the shock wave, the reactive mixture is excited along the center of the tube with a 266-nm laser beam directed through a window in the end wall of the shock tube. The emitted LIF signal is collected through elongated sidewall windows and focused onto the entrance slit of an imaging spectrometer coupled to an intensified CCD camera. The one-dimensional spatial resolution of the measurement translates into a reaction-time-resolved measurement while the species information can be gained from the spectral axis of the detected two-dimensional image. Anisole pyrolysis was selected as the benchmark reaction to demonstrate the new apparatus.

Abstract
AbstractPrimary malignant melanomas of the central nervous system (CNS) are rarely seen entities in the clinical routine. Primary amelanotic melanomas are even rarer. In our literature review, we found only six case reports of primary amelanotic CNS melanomas. Our case report describes the course of a 71-year-old man with a primary amelanotic CNS melanoma with secondary spread to the spine.

Abstract
BACKGROUND Ipilimumab is a cytotoxic T-lymphocyte antigen-4 antibody that enhances T-cell activity and proliferation. METHODS In a retrospective analysis of 86 patients the clinical benefits of ipilimumab treatment were correlated with laboratory and clinical data. RESULTS A lactate dehydrogenase (LDH) value within the normal range before the start of therapy was significantly correlated with better OS (p ≤ 0.009). An increase in LDH level after two cycles was indicative of a poor outcome, and was significantly negatively correlated with treatment response and overall survival and progression-free survival. 42% of all patients suffered from autoimmune toxicity (CTCAE grades 2-4). The occurrence of autoimmune toxicity clearly correlated with clinical benefit. CONCLUSION Changes in LDH level and side effects correlate with response to therapy and survival.

Abstract
Diode laser-based multi-wavelength near-infrared (NIR) absorption in aqueous films is a promising diagnostic for making temporally resolved, simultaneous measurements of film thickness, temperature, and concentration of a solute. Our previous work in aqueous urea solutions aimed at determining simultaneously two of these system parameters, while the third one must be fixed or specified by additional measurements. The current work presents a simultaneous NIR absorption-based multi-parameter measurement of thickness, temperature, and solute concentration coupled with the Bayesian methodology that is used to infer probability densities for the obtained data. The Bayesian analysis is based on a temperature- and concentration-dependent spectral database generated with a Fourier transform infrared spectrometer in the range 5500-8000 cm-1 for water with variable temperature and urea concentration. The concept was first validated with measurements using a calibration cell. Probability densities in the measured parameters were quantified using a Markov chain Monte Carlo algorithm, which were used to derive credibility intervals. As a practical demonstration, the temporal variation of film thickness, urea concentration, and liquid temperature were recorded during evaporation of a liquid film deposited on a transparent heated quartz plate.
