Published: April 2019

AbstractElevated atmospheric CO2 concentration ([CO2]) can stimulate plant growth through enhanced photosynthetic rate. However, plant C, N and P ratios in response to elevated [CO2] combined with canopy warming in rice-winter wheat rotation system remain largely unknown. Here we investigated the impacts of elevated [CO2] and warming on plant nutrient ratios under open-air conditions. Four treatments including the ambient condition (CK), elevated [CO2] (500 ppm, CE), canopy warming (+2 °C, WA), and the combination of elevated [CO2] and warming (CW) were used to investigate the responses of plant C, N and P ratios in a rice-winter wheat rotation system in southeast China. Results showed that elevated [CO2] increased C:N ratio in whole plant by 8.4–14.3% for both crops, and increased C:P ratio by 11.3% for rice. The changes in ratio were due to an increase in C concentration by 0.8–1.2% and a reduction in N concentration by 7.4–10.7% for both crops, and a reduction in P concentration by 10.0% for rice. Warming increased N allocation in rice leaf and N concentration by 12.4% for rice, resulting in increases in the ratios of N to C and P by 11.9% and 9.7% in rice, but not in wheat. However, CW had no effect on plant C:N ratio in rice, indicating the positive effect of elevated [CO2] could offset the negative impact of warming on C:N ratio. By contrast, CW significantly decreased plant C:P and N:P ratios by 16% due to the increase in P allocation in stem for wheat. These results suggest that impacts of climate change on plant nutrient balance occur through interactions between the effects of climate change on nutrient uptake and allocation, which is important for food quality and productivity under global climate change.

Published: April 2019

AbstractAbundant literature has studied the behavioral and neural correlates of deception, but little research has focused on the internal cost of spontaneous deception. In the present study, the event-related potential and event-related spectral perturbations techniques were used to measure the internal cost of spontaneous deception by having participants perform a sender–receiver task in which they decided whether to send deceptive messages to increase their payoff from the task. Several important main findings emerged from this study. We observed a reward positivity (RewP) after senders sent the message, suggesting an integration of reward with associated cost after response in our task. Furthermore, spontaneous deception decreased the amplitude of the RewP and power in the delta and beta bands, whereas it increased the amplitude of power in the theta band, indicating that deception carried an internal cost that devalued individuals’ rewards.
Direct mapping of hydrangea blue-complex in sepal tissues of Hydrangea macrophylla
Authors: Ito Takaaki , Aoki Dan , Fukushima Kazuhiko , Yoshida Kumi 
Published: April 2019

AbstractThe original sepal color of Hydrangea macrophylla is blue, although it is well known that sepal color easily changes from blue through purple to red. All the colors are due to a unique anthocyanin, 3-O-glucosyldelphinidin, and both aluminum ion (Al3+) and copigments, 5-O-caffeoyl and/or 5-O-p-coumaroylquinic acid are essential for blue coloration. A mixture of 3-O-glucosyldelphinidin, 5-O-acylquinic acid, and Al3+ in a buffer solution at pH 4 produces a stable blue solution with visible absorption and circular dichroism spectra identical to those of the sepals, then, we named this blue pigment as ‘hydrangea blue-complex’. The hydrangea blue-complex consists of 3-O-glucosyldelphinidin, Al3+, and 5-O-acylquinic acid in a ratio 1:1:1 as determined by the electrospray ionization time-of-flight mass spectrometry and nuclear magnetic resonance spectra. To map the distribution of hydrangea blue-complex in sepal tissues, we carried out cryo-time-of-flight secondary ion mass spectrometry analysis. The spectrum of the reproduced hydrangea blue-complex with negative mode-detection gave a molecular ion at m/z = 841, which was consistent with the results of ESI-TOF MS. The same molecular ion peak at m/z = 841 was detected in freeze-fixed blue sepal-tissue. In sepal tissues, the blue cells were located in the second layer and the mass spectrometry imaging of the ion attributable to hydrangea blue-complex overlapped with the same area of the blue cells. In colorless epidermal cells, atomic ion of Al3+ was hardly detected and potassium adduct ion of 5-O-caffeoyl and/or 3-O-acylquinic acid were found. This is the first report about the distribution of aluminum, potassium, hydrangea blue-complex, and copigment in sepal tissues and the first evidence that aluminum and hydrangea blue-complex exist in blue sepal cells and are involved in blue coloration.
Defining Dysbiosis in Patients with Urolithiasis

Published: April 2019

AbstractThe prevalence of urinary stone disease (USD) is rapidly rising. However, the factors driving this increase are unknown. Recent microbiome studies suggest that dysbiosis may in part contribute to the increasing prevalence. The objective of the current study was to determine the nature and location of dysbiosis associated with USD. We conducted microbiome analysis from the gastrointestinal and urinary tracts, along with a metabolomic analysis of the urinary metabolome, from subjects with an active episode of USD or no history of the disease. Higher rates of antibiotic use among USD patients along with integrated microbiome and metabolomic results support the hypothesis that USD is associated with an antibiotic-driven shift in the microbiome from one that protects against USD to one that promotes the disease. Specifically, our study implicates urinary tract Lactobacillus and Enterobacteriaceae in protective and pathogenic roles for USD, respectively, which conventional, culture-based methods of bacterial analysis from urine and kidney stones would not necessarily detect. Results suggest that antibiotics produce a long-term shift in the microbiome that may increase the risk for USD, with the urinary tract microbiome holding more relevance for USD than the gut microbiome.
Strong and ductile AZ31 Mg alloy with a layered bimodal structure
Authors: Luo Xuan , Huang Tianlin , Wang Yuhui , Xin Yunchang , Wu Guilin 
Published: April 2019

AbstractAZ31 Mg alloy was processed by accumulative roll-bonding (ARB) and hot rolling (HR), respectively, followed by annealing. Layered bimodal structures characterized by an alternative distribution of fine-grained layers and coarse-grained layers were obtained in the ARB samples, while mixed bimodal structures were achieved in the HR samples. The ARB samples have superior combinations of high strength and good elongation compared to the HR samples, indicating a clear effect of layered bimodal structures on mechanical properties of the alloy. The strength of the ARB samples is related to the grain size; while the ductility is attributed to the activity of non-basal slip and the strong backstress.

CT pelvis showed loose intrapelvic migrated cup, extensive osteolytic acetabular defects, and pelvic discontinuity.
Pararectus approach was used to remove the cup and the head with concomitant plating of the anterior column

Conclusion: The pararectus approach is a valid option for intrapelvic cup extraction and pelvic discontinuity fixation.
Die lasche Beobachtung eines Staatsfeindes: Der DDR- und bundesdeutsche Psychiater und Psychotherapeut Dietfried Müller-Hegemann in den Akten der Stasi
Authors: Steinberg Holger 
Published: April 2019

ZusammenfassungDiese Untersuchung ist die erste, die bewusst und gezielt das vom Ministerium für Staatssicherheit der DDR (MfS) über Jahrzehnte gesammelte Material über einen Psychiater zusammenträgt und auswertet.Grundlage bilden die Akten der Behörde des Bundesbeauftragten für die Unterlagen des Staatssicherheitsdienstes der ehemaligen DDR (BStU), die einen Bezug zur Person Dietfried Müller-Hegemanns (1910-1989) aufweisen. Diese Sammlung von Akten verschiedenster Provenienz und aus unterschiedlichen Themenzusammenhängen enthält quantitativ und qualitativ sehr unterschiedlich relevantes Material.Müller-Hegemanns Karriere in der DDR unterlag in den 1950er-Jahren einem politisch gewollten Auf- und schließlich in den 1960er-Jahren Abstieg, bis er 1971 in die Bundesrepublik wechselte. Einerseits lehnt sich das Material zwar eng an die Spezifität des hier präsentierten Falles an, andererseits aber eignet dieser sich sicherlich insofern als Exempel als man das allgemein übliche Vorgehen des MfS gut erkennen kann. Die hier ausgewerteten Quellen zeigen, dass obwohl Müller-Hegemann ab Ende der 1950er-Jahre zumindest von leitenden ministeriellen Mitarbeitern als auch von einzelnen SED-Hierarchien sogar als ‘Staatsfeind’ eingestuft und bekämpft worden war, er jedoch niemals gezielt in den Fokus des MfS geriet. Erst nach seiner ‘Republikflucht’ 1971 wurde er erstmals Gegenstand einer ‘operativen Bearbeitung’.Die Zweifelhaftigkeit der Ermittlungsmethodik des MfS sowie das niemals vollständige Erreichen seiner Ziele, so hier z. B. den menschlichen Kontakt zu Zurückgelassenen vollständig zu unterbinden, stehen in diesem konkreten Fall als Beispiele dafür, dass das MfS an Grenzen stieß. Des Weiteren soll die in der Forschung aufzufindende Auffassung, dass Psychiater besonders im Fokus des MfS standen, aufgrund des hier untersuchten Einzelfalles zwar nicht angezweifelt werden, jedoch kann die Beobachtung Müller-Hegemanns nur als ausgesprochen lasch bezeichnet werden.

Published: April 2019

ZusammenfassungRegelmäßige körperliche Aktivität ist eine wichtige Voraussetzung für die Gesundheit und die Entwicklung von Kindern und Jugendlichen. Insbesondere während aber auch nach einer Krebserkrankung sind Kinder und Jugendliche jedoch in sehr geringem Umfang körperlich aktiv und weisen eine stark ausgeprägte körperliche Inaktivität auf. Diese chronische körperlich-motorische Unterforderung hat, zusätzlich zu den Nebenwirkungen der Behandlung, weitere negative Folgen für die Gesundheit, wie z. B. starke Einbußen der körperlichen Leistungsfähigkeit und der Lebensqualität. Um diese Folgen zu verringern, kann den PatientInnen im Rahmen von gezielten sporttherapeutischen Bewegungsangeboten Zugang zu regelmäßiger körperlicher Aktivität ermöglicht werden. Bewegungsförderung für Kinder und Jugendliche mit Krebserkrankungen stellt eine supportive Maßnahme zur Verbesserung und Erhaltung der funktionalen Mobilität, der körperlichen Leistungsfähigkeit und der gesundheitsbezogenen Lebensqualität dar. Für eine nachhaltige Bewegungsförderung müssen sowohl die Verhaltensebene (Person) als auch die Verhältnisebene (Lebenswelt) berücksichtigt werden. Anhand des Leipziger Bewegungskonzepts werden Einflussebenen auf die körperliche Aktivität von Kindern und Jugendlichen mit Krebserkrankungen erläutert sowie inhaltliche, systemische und strukturelle Voraussetzungen für die Implementierung einer behandlungsbegleitenden Bewegungsförderung in der Pädiatrischen Onkologie beschrieben. Zusätzlich werden Finanzierungsmöglichkeiten, basierend auf dem SGB V §43, aufgezeigt.

Published: April 2019

AbstractTo examine measures of total and regional body composition using dual X-ray absorptiometry (DXA) in NCAA Division I collegiate equestrian athletes, 31 female collegiate equestrian athletes were matched to a population of normal controls by age and body mass index. Total and regional fat tissue mass (FM), lean tissue mass (LM), bone mineral density (BMD), and abdominal visceral adipose tissue (VAT) were measured by DXA. Equestrian athletes had a significantly (p=0.03) lower total body fat percentage (%fat) than controls. There were no significant differences in total LM and VAT between equestrian athletes and controls. However, equestrian athletes, when compared to the controls, had significantly lower leg %fat, leg FM and higher leg LM. The greater leg LM in equestrian riders resulted in a smaller upper to lower body LM ratio compared to controls. There was no difference in leg BMD between equestrian athletes and controls. There were no significant differences between the 2 styles of riding (i. e., hunt seat and western style) in regards to body composition. The lower total %fat in equestrian athletes seems to be influenced by differences in leg composition, with equestrian athletes having significantly more LM and less FM.
A Cautious Note on Thalidomide Usage in Cancer Treatment: Genetic Profiling of the TBX2 Sub-Family Gene Expression is Required
Authors: Nemer Georges , Khalil Athar 
Published: April 2019

AbstractThalidomide is still by excellence the mysterious drug that fascinated, blurred, misled, and changed the scientific community perspectives and policies. It was introduced in the 1950’s as a sedative drug, then shortly withdrawn because of the devastating birth defects that affected tens of thousands throughout more than 40 countries. Back into the market in the mid 1990’s and 2000’s the drug is now being used to treat skin immune-related conditions and some cancers like multiple myeloma. Despite numerous beneficial effects which led to the development of new analogs, its direct mechanisms of action are still elusive. The identification of CRBN and TBX5 as potential direct ligands for this drug have opened the way to better understand its efficiency and its failure.We hereby review these mechanisms and provide evidence that could explain why thalidomide failed to make it as a drug of choice in lung cancer treatment. Linking the genetic signature of TBX2 subfamily in these tumors to their inability to respond properly to thalidomide raises concerns of worsening lung cancer patients’ health if this drug is utilized.

Published: April 2019

AbstractWe describe an effective suture technique to control the persistent subannular bleeding at the aortoventricular curtain in four patients with aortic stenosis and small annulus who underwent aortic root enlargement and patch reconstruction. This technique approximates the left atrial roof to the aortic root without the need for re-replacement of the aortic prosthesis or revision of the patch. Reintervention for aortic root, valve, or the residual aorta was not required.
Correlation between Lumbar Spine Facet Joint Orientation and Intervertebral Disk Degeneration: A Positional MRI Analysis
Authors: Jiang Xin , Chen Dong , Li Zhongshi , Lou Yahao 
Published: April 2019

Background and Study Aims The contribution of facet joint orientation (FO) to degeneration of the functional units of the lumbar spine remains unclear. The study used positional magnetic resonance imaging (MRI) to evaluate the association between intervertebral disk degeneration and FO at the L3–L4 to L5–S1 spinal segments.
Material and Methods This was a retrospective study of 450 outpatients admitted to the Spine Surgery Department of our hospital between January 2013 and January 2015 and with positional lumbar MRI data. Grade of intervertebral disk degeneration, FO relative to the midsagittal plane, vertebral translation (VT), and angular variation (AV) were assessed.
Results No effect of baseline characteristics (age, sex, and body mass index) on intervertebral disk degeneration was observed. A significant difference in VT and AV was only present between grades 1 + 2 versus 4 at L5–S1 (both p = 0.005), and in FO only at L5–S1 between grades 1 + 2 versus 4 (p = 0.03) and grades 3 versus 4 (p = 0.04). AV and VT were correlated at all three lumbar segments (r = 0.224–0.309; p ≥ 0.01), with a correlation between FO and AV only at L3–L4 (r = 0.141; p = 0.035).
Conclusion Disk degeneration was associated with FO only at L5–S1. AV and VT of spinal segments of the mid to lower lumbar spine did not correlate with FO.

Published: April 2019

AbstractWe treated an extremely rare case of osteoid osteoma of the pisiform. Pisiform hypertrophy caused persistent pain and ulnar nerve irritation at Guyon's canal after the initial trauma. The re-enlargement of the pisiform attracted our attention allowing us to ultimately diagnose the condition as osteoid osteoma and treat the patient with a successful clinical result.
Origins of a Menschendarstellerin: Characterization and Operatic Performance in Fin-de-siècle Vienna
Authors: Gudesblatt Melanie 
Published: April 2019

AbstractIn fin-de-siècle Vienna frustrations with ‘lifelessness’ began to boil over. Unlike previous generations of opera-goers, however, the Viennese did not so much fear singers becoming automata as desire dramatic performance that foregrounded humanness and subjectivity. Critics increasingly fetishized vitality – manifested in characters with dramatic integrity and singers capable of nestling themselves in their roles – and by 1910 wanted singers to communicate their own interiority and ‘wilfulness’ as well. This article uses the reception of the soprano Marie Gutheil-Schoder (1874–1935) to demonstrate the growing currency of these imperatives. A controversial hire for the Hofoper, she was initially disparaged by critics as vocally ‘weak’, but the Viennese gradually ‘learnt to love this voice’ for the way in which it could be pressed into the service of the drama and her will. I explain her changing fortunes, arguing that opera-goers valued certain voices in accordance with evolving conceptions of characterization, acting technique and human subjectivity.
Boris Asafiev in 1948
Authors: Zuk Patrick 
Published: April 2019

AbstractThe venerable founder of Soviet musicology Boris Asafiev aroused widespread dismay by his actions in 1948 after the promulgation of a Central Committee resolution condemning the USSR's leading composers: he not only acquiesced in his appointment as chairman of the Composers’ Union, but agreed to give a keynote address endorsing the resolution at its first national congress. His admirers have claimed that he must have been coerced into collaboration and that his address did not reflect his real views. The present essay re-examines the circumstances, arguing that the evidence of Asafiev's willing complicity is overwhelming. A close analysis of his keynote address reveals its contents to be wholly consistent with views that he had regularly expressed throughout his career, as one of the principal progenitors of an anti-modernist, ethnic nationalist and xenophobic strain in Soviet writing on music that was given forceful expression in the 1948 resolution.
RETRACTED: One-Leap Fuzzy Enabled Clustering Technique for Under Water Wireless Sensor Networks to Improve the Stability and Energy Exhaustion Rate of the Nodes

Published: April 2019

Abstract
UWSNs will find packages in information series, oceanographic, environmental monitoring and surveillance. UWSNs are difficult to deploy and collect data where the conditions are unpredictable and unreliable. These UWSN nodes collaborate together and perform collective operations which is highly challenging due to the prevailing factors. The fact underwater communications are significantly laid low with network dynamics, because of massive inter-diffusion delays are true. The communication dynamics within the UWSN could be influenced greatly by the integrity of the nodes in the network. The motto of this technique is to alleviate the exhaustion rate and aggravate the stability of the network with cluster head selection algorithm and proposed algorithm One-Leap Fuzzy based Clustering Technique (OL-FCT). Cluster head selection process will be performed with particle swarm optimization approach. The experimental consequences of the work compared with the present strategies shows that OL-FCT performs better than other techniques.
Pregnancy in women with cystinosis

Published: April 2019

Abstract
Cystinosis is a rare autosomal recessive disease causing cystine deposition in all tissues, primarily affecting the kidneys. There are few published reports of pregnancy in women with cystinosis, and little evidence is available regarding optimal management. Kidney transplantation and cystine-depleting therapy have transformed the prognosis of cystinosis, and pregnancy is increasingly considered. The evidence base for cystinosis management in pregnancy, therefore, requires expansion. We report three successful pregnancy outcomes and five early pregnancy losses in two women with cystinosis. The challenges of pregnancy in patients with cystinosis are discussed. Pre-pregnancy planning and antenatal management in a specialist renal obstetric clinic are paramount.
Enhanced SVM–KPCA Method for Brain MR Image Classification

Published: April 2019

Abstract
Automated classification of magnetic resonance brain images (MRIs) is a hot topic in the field of medical and biomedical imaging. Various methods have been suggested recently to improve this technology. In this paper, to reduce the complexity involved in the medical images and to ameliorate the classification of MRIs, a novel 3D magnetic resonance (MR) brain image classifier using kernel principal component analysis (KPCA) and support vector machines (SVMs) is proposed. Experiments are carried out using A deep multiple kernel SVM (DMK-SVM) and a regular SVM. An algorithm entitled SVM–KPCA is put forward. Its main task is to classify a brain MRI as a normal brain image or as a pathological brain image. This algorithm, firstly, adopts the discrete wavelet transform technique to extract features from images. Secondly, KPCA is applied to decrease the dimensionality of features. SVM is then applied to the reduced data. A K-fold cross-validation strategy is used to avoid overfitting and to ameliorate the generalization of the SVM–KPCA algorithm. Three databases are used to validate the suggested SVM–KPCA method. Three conclusions are obtained from this work. First, KPCA is highly efficient in increasing the classifier’s performance compared with similar algorithms working on the proposed database. Second, the SVM–KPCA algorithm performs well in differentiating between two classes of medical images. Third, the approach is robust and might be utilized for other MRIs. This proposes a significant role for computer aided diagnosis analysis systems used for clinical practice.
