Skillful statistical models to predict seasonal wind speed and solar radiation in a Yangtze River estuary case study
Authors: Zeng Peng , Sun Xun , Farnham David J. 
Published: May 2020

AbstractThis paper illustrates the potential for seasonal prediction of wind and solar energy resources through a case study in the Yangtze River estuary. Sea surface temperature and geopotential height-based climate predictors, each with high correlation to ensuing seasonal wind speed and solar radiation at the Baoshan weather observing station, are identified and used to build statistical models to predict seasonal wind speed and solar radiation. Leave-one-out-cross-validation is applied to verify the predictive skill of the best performing candidate model for each season. We find that predictive skill is highest for both wind speed and solar radiation during winter, and lowest during summer. Specifically, we find the most skill when using climate information from the July-September season to predict wind speed or solar radiation during the subsequent November-January season. The ability to predict wind and solar energy availability in the upcoming season can help energy system planners and operators anticipate seasonal surpluses or shortfalls and take precautionary actions.

AbstractTo evaluate the relationship of the extent and quantitative intensity of background parenchymal enhancement (BPE) on contrast-enhanced spectral mammography (CESM) with age, breast density, menstruation status, and menstrual cycle timing. This retrospective study included women who underwent CESM from July 2017 to March 2019 and who had menstruation status records. BPE category assessment was performed subjectively. BPE intensity was quantitatively measured using regions-of-interest. 208 subjects were included (150 were regular menstrual cycle and 58 were postmenopausal). The breast density was classified as category B in 11 subjects, category C in 231 subjects, and category D in 23 subjects. Subjects based on menstrual cycle timing, 24 at days 1–7, 55 at days 8–14, 48 at days 15–21, and 23 at days 22–28. Both quantitative and categorical analyses show a weak negative correlation between BPE and age in all subjects, but there was no significant correlation in premenopausal patients. Both the BPE pixel intensity value and BPE category was significantly lower in postmenopausal patients than in premenopausal patients, and there was no significant difference in breast density according to BPE. The minimum and maximum pixel values of BPE on days 8–14 of the menstrual cycle was significantly lower than those on days 15–21. There was no correlation between BPE level and menstrual cycle timing. Breast density with category D was more likely to have a lower BPE level than category C. We show here that BPE level is affected by menstruation status and menstrual cycle timing. We suggest that CESM should not be performed on days 15–21 of the menstrual cycle, but on days 8–14.

AbstractPlastic represents 60-80% of litter in the ocean. Degradation of plastic to small fragments leads to the formation of microplastics (MPs <5 mm) and nanoplastics (NPs <1 µm). One of the most widely used and representative plastics found in the ocean is polystyrene (PS). Among marine organisms, the immune system of bivalves is recognized as suitable to assess nanomaterial toxicity. Hemocyte subpopulations [R1 (large granular cells), R2 (small semi-granular cells) and R3 (small agranular or hyaline cells)] of Mytilus galloprovincialis are specialized in particular tasks and functions. The authors propose to examine the effects of different sizes (50 nm, 100 nm and 1 μm) PS NPs on the different immune cells of mussels when they were exposed to (1 and 10 mg·L−1) of PS NPs. The most noteworthy results found in this work are: (i) 1 µm PS NPs provoked higher immunological responses with respect to 50 and 100 nm PS NPs, possibly related to the higher stability in size and shape in hemolymph serum, (ii) the R1 subpopulation was the most affected with respect to R2 and R3 concerning immunological responses and (iii) an increase in the release of toxic radicals, apoptotic signals, tracking of lysosomes and a decrease in phagocytic activity was found in R1.

Context.The large astrometric and photometric survey performed by theGaiamission allows for a panoptic view of the Galactic disc and its stellar cluster population. Hundreds of stellar clusters were only discovered after the latestGaiadata release (DR2) and have yet to be characterised.Aims.Here we make use of the deep and homogeneousGaiaphotometry down toG= 18 to estimate the distance, age, and interstellar reddening for about 2000 stellar clusters identified withGaiaDR2 astrometry. We use these objects to study the structure and evolution of the Galactic disc.Methods.We relied on a set of objects with well-determined parameters in the literature to train an artificial neural network to estimate parameters from theGaiaphotometry of cluster members and their mean parallax.Results.We obtain reliable parameters for 1867 clusters. Our catalogue confirms the relative lack of old stellar clusters in the inner disc (with a few notable exceptions). We also quantify and discuss the variation of scale height with cluster age, and we detect the Galactic warp in the distribution of old clusters.Conclusions.This work results in a large and homogeneous cluster catalogue, allowing one to trace the structure of the disc out to distances of ∼4 kpc. However, the present sample is still unable to trace the outer spiral arm of the Milky Way, which indicates that the outer disc cluster census might still be incomplete.
Functional Knee Performance Differences in Handball are Depending on Playing Class

Published: May 2020

AbstractHandball is one of the most traumatic sports. The knee is the most commonly injured joint. To prevent knee injuries, optimal functional knee stability is of great importance. Nevertheless, there is still no consensus about objective criteria for knee function. Depending on playing class, injury rates seem to differ. The purpose of this study was to evaluate knee function in handball depending on playing class and to establish reference data for functional knee stability. 261 handball players (25.1±5.8 years) performed a functional test including two- and one-legged stability assessments, jump tests, speed and agility analysis. Except for balance, differences between playing classes were detected in all tests with superior performance of high-class players (Germany’s 1st (“Oberliga”) and 2nd (“Verbandsliga”) non-elite playing class). High-class players achieved significant better results in jumping height (p≤0.011–0.029), relative power per body weight in the two-legged counter movement jump (p≤0.023) and speed and agility tests (p≤0.001). This study illustrates the relevance of playing class specific screening. Sports and playing class-specific databases will help to identify individual deficits and strengths in order to prevent injury and increase performance. Moreover, objective criteria for return to sports can be established.
Eine außergewöhnliche Therapie der Vena-iliaca-externa-Hypoplasie bei einer Patientin mit Klippel-Trénaunay-Syndrom – ein Fallbericht
Authors: Cyrek Anna Ewa 
Published: May 2020

ZusammenfassungDas Klippel-Trénaunay-Syndrom (KTS) ist eine seltene und komplexe Fehlbildung. Sie zeigt die typische Trias aus vaskulärer Malformation, Knochen- und Weichteilhypertrophie sowie venöser Varikosis. Die Systemmanifestationen werden in einem individuell variablen Muster beobachtet. Eine isolierte angeborene Hypoplasie des venösen Systems tritt jedoch in den seltensten Fällen auf. Aus diesem Grund spielt die Früherkennung eine wichtige Rolle für die weitere Behandlungsplanung. So können durch rechtzeitige Behandlung schwere Krankheitsverläufe oder Spätfolgen vermieden werden. Eine isolierte angeborene Hypoplasie ist extrem selten und prädisponiert insbesondere im jungen Erwachsenenalter für Becken- oder Beinvenenthrombosen. Bei dieser Krankheit wird selten eine chirurgische Rekonstruktion durchgeführt.Wir beschreiben einen sehr seltenen Fall einer 60-jährigen Frau mit KTS, die vor 28 Jahren einen venösen Crossover-Bypass (Palma) mittels Vena saphena magna bei Hypoplasie der Vena iliaca externa rechts erhalten hat. Das Ziel des vorliegenden Berichts ist das klinische Erscheinungsbild, den diagnostischen Prozess und das Krankheitsmanagement vorzustellen sowie eine Literaturübersicht zum operativen Behandlungsverfahren darzustellen.

Abstract
Background and study aims The best method for endoscopic placement of self-expandable metallic stents (SEMS) for distal malignant biliary obstruction (MBO) has not yet been determined. The aim of this study was to evaluate how SEMS placement above the papilla and without endoscopic sphincterotomy (EST) impacts the time to recurrent biliary obstruction (RBO) in patients with distal MBO.
Patients and methods We retrospectively reviewed data for 73 consecutive patients with unresectable distal MBO who underwent endoscopic SEMS placement for the first time at our institution between April 2014 and March 2016. We compared time to RBO of SEMS placement above the papilla (intraductal placement) with SEMS placement across the papilla (transpapillary placement). In the intraductal placement group, we also compared time to RBO of placement without EST with placement with EST.
Results Endoscopic SEMS placement was performed in 30 patients with intraductal placement and in 43 patients with transpapillary placement. The median time to RBO was significantly longer with intraductal placement (307 days) than with transpapillary placement (161 days) (P = 0.022). Complication rates did not differ between the two groups. In both univariate and multivariate analysis, intraductal placement was an independent factor contributing to prolonged time to RBO. In intraductal placement, time to RBO was significantly longer in SEMS placement without EST than with EST (363 days vs. 227 days, respectively; P = 0.026).
Conclusions Intraductal SEMS placement, especially without EST for distal MBO contributed to longer time to RBO.

Authors: Stenger Dietmar , Hartmann Michael 
Published: May 2020

AbstractA correct crossectomy of the small saphenous vein, as stipulated by Hach and Mumme, is seldom carried out in literature. The two authors thoroughly describe the technical procedure of a high, flush ligation of the saphenopopliteal junction (SPJ). The risks and problems of the surgery are described and illustrated.A retrospective cohort study with the aim of conducting a flat small saphenous crossectomy yielded the following findings in 187 operated legs: small saphenous remainder stumps with clinically relevant recurrence in 2.1 %, small saphenous neovasculature with clinically relevant recurrence in 1.1 %, junction stump or neovasculature without clinically relevant recurrence in 1.6 % of cases. In summation, the total amount of actual recurrences was 4.8 %.
Saphenofemoral recurrence from an an anatomist’s point of view
Authors: Brenner Erich 
Published: May 2020

AbstractFrom an anatomical point of view, recurrences at the saphenofemoral junction (SFJ) could result from various sources. For one, it could be caused by a recanalisation of an originally occluded great saphenous vein (GSV). Secondly, another vein in the junction region could take over the function of the GSV and dilate. A third variation is a – more or less successful – generation of a new vein. In the last case, a sufficient vein could be generated, an insufficient vein could arise, or an inadequate venous regeneration, so that a cluster of frail but incomplete vasculature remains (neovasculature).
Small Cell Lung Cancer: Advances in Diagnosis and Management
Authors: Chauhan Ayushi F. , Liu Stephen V. 
Published: May 2020

AbstractSmall cell lung cancer (SCLC) is an aggressive subtype of lung cancer characterized by rapid growth and early spread. It is a highly lethal disease that typically is diagnosed at a late stage. Surgery plays a very small role in this cancer, and management typically involves chemotherapy, delivered with thoracic radiation in early-stage disease. Platinum-based chemotherapy is initially very effective, inducing rapid and often deep responses. These responses, though, are transient, and upon relapse, SCLC is highly refractory to therapy. Immunotherapy has shown promise in delivering meaningful, durable responses and the addition of immunotherapy to first-line chemotherapy has led to the first improvements in survival in decades. Still, the disease remains difficult to manage. Incorporating radiation therapy at specific points in patient management may improve disease control. The development of predictive biomarkers and novel targeted therapies will hopefully improve options for patients in the near future. This review focuses on the current standards of care and future directions.
Recent Developments in C–C Bond Formation Using Catalytic Reductive Coupling Strategies
Authors: Sieber Joshua D. , Agrawal Toolika 
Published: May 2020

Metal-catalyzed reductive coupling processes have emerged as a powerful methodology for the introduction of molecular complexity from simple starting materials. These methods allow for an orthogonal approach to that of redox-neutral strategies for the formation of C–C bonds by enabling cross-coupling of starting materials not applicable to redox-neutral chemistry. This short review summarizes the most recent developments in the area of metal-catalyzed reductive coupling utilizing catalyst turnover by a stoichiometric reductant that becomes incorporated in the final product.1	Introduction2	Ni Catalysis3	Cu Catalysis4	Ru, Rh, and Ir Catalysis4.1	Alkenes4.2	1,3-Dienes4.3	Allenes4.4	Alkynes4.5	Enynes5	Fe, Co, and Mn Catalysis6	Conclusion and Outlook

Published: May 2020

Abstract
Objectives Refugees encounter several health disparities including oral health problems. This study evaluated the self-reported oral health status, practices, and access to care of adult refugees living in San Antonio, Texas, United States.
Materials and Methods Adult refugees (n = 207) who accessed services from two centers in San Antonio, completed this survey. Multivariate logistic regression was used to examine the relationship of the refugees’ demographics with oral health status, practices, and access to care.
Results Oral pain in the previous 12 months was common among refugees having been reported by almost 58.9% of the survey participants; 43% reported pain as the reason for their last dental visit. Approximately half of the participants reported both the condition to their teeth and gums as being good: 42.5 and 54.6%, respectively. Most participants (84%) reported brushing their teeth one or two times a day, and around 78% reported they never smoked. Fifty-two percent reported needing dental care in the past 12 months, but not being able to receive it; while 45.9% reported not having dental insurance, 41.5% reported not having money to pay a dentist. Fifteen percent reported never visiting a dentist. Arabic speakers, moving to the United States more recently, and lower level of education were associated with a poor oral health status and practices (p < 0.05).
Conclusion Refugees in this study encountered limited access to dental care. Their inability to seek dental care could affect their oral and general health, weaken efforts of preventing oral health diseases, and restrict their full inclusion into the community.

Published: May 2020

Abstract
HINT1 gene mutations cause an axonal neuropathy with some specific findings including presence of neuromyotonia, autosomal recessive inheritance, onset in the first decade, and primary motor involvement. In this case report, we described an 18-year-old female patient who presented to the clinic with gait instability and muscle stiffness. A homozygous novel c.180_181delAT (p.Ser61Profs*8) variant in the HINT1 gene was found by clinical exome analysis. Parents were heterozygous for the same variant. The patient was diagnosed with autosomal recessive axonal neuropathy with neuromyotonia. The presence of neuromyotonia must be evaluated in patients with hereditary axonal neuropathies as this can help the diagnosis prior to genetic testing.

Published: May 2020

AbstractPrimary liver cancer is the seventh most common cancer worldwide and is the second leading cause of cancer-related death. Hepatocellular carcinoma (HCC) accounts for three-quarters of primary liver cancers and less than a third of patients present with curable disease. Liver-directed therapy is essential for the treatment of patients with unresectable HCC and the advancement of stereotactic body radiation therapy (SBRT) has made radiation a safe and effective treatment option in a range of clinical presentations. In this review, we discuss the technical aspects of SBRT and the general approach to treatment of HCC. We explore the use of SBRT for bridging to transplant, downstaging, and the treatment of large tumors and portal vein tumor thrombus. Although there is limited high-quality randomized data, we review the evidence comparing SBRT with other liver-directed therapies and explore areas for future investigation.

Published: May 2020

AbstractObjectives Liquid coconut shell smoke (LC-SS) is used in natural food preservation for a long history. The purpose of this study was to analyze the role of LC-SS in macrophage responses during diabetic oral ulcer healing as medication.Materials and Methods Oral ulcers were induced in the labial lower mucosa of the research subjects using a round steel blade following diabetic induction by means of alloxan. Twenty-four diabetic Wistar rats presenting oral ulcers were divided into two groups, a test group, which was given topical treatment of LC-SS and a control group, which was given benzydamine hydrochloride (BHCl). The role of LC-SS in macrophages was assessed by means of immunohistochemistry for nuclear factor kappa B (NF-κB) and tumor necrosis factor-α (TNF-α) expression.Result LC-SS increased macrophages compared with BHCl (p = 0.000). The LC-SS affected only TNF-α expression by stimulating NF-κB expression (p = 0.046) but did not macrophage numbers (p = 0.861).Conclusion LC-SS has a stronger effect compared with BHCl on diabetic oral ulcer healing by increasing macrophage response to produce TNF-α while decreasing NF-κB expression.
Understanding stancetaking through gestures and linguistic practices in a
public political debate in Hong Kong
Authors: Wan Helen 
Published: May 2020

Abstract
Hong Kong has enjoyed partial universal suffrage in both
District Council election as well as the Legislative Council election since the
handover in 1997. This paper looks into the 2016 Hong Kong Legislative Council
electoral debate with the combination of discourse analysis using the Stance
Triangle (Du Bois 2007) and
gesture-unit analysis (Kendon 2004) to
study how verbal and non-verbal activities are being strategically organized to
project both affective and epistemic stances by the elected incumbent, Alvin
Yeung, and his opponents. The findings suggest Cantonese utterance final particles
and gestures are strategically and aptly employed to achieve both expressive and
communicative purposes in the political debates where they can not only elucidate
their policy agenda but also defeat the opponents and win the votes.
Impact of power relations on news translation in China
Authors: Xia Liang 
Published: May 2020

Abstract
Global news transmission relies on language and particularly
on the services of translation. Decision making exists in every step of the
translation process, for instance, from the text selection to the discursive
expression, and from information transference to culture communication. This study
examines the translation practice of news in Cankao Xiaoxi
(Chinese: 参考消息), the most read Chinese daily run by the Chinese
government that collects various news or information from international media,
translates and reprints them in Chinese. This study outlines various powers that
underline text manipulation in this state news agency and explores the impact of
power relations on both the process and the product of news translation. Combining
an ethnographic approach with a critical discourse analysis of news translation,
this study investigates the institutional contexts and human agencies involved in
the news making process, which lead to the manipulation of the news production.
This study reveals that various powers determine how to shape the already shaped
news via translating and that network of power relations underlying news
translation in China is hierarchical. This hierarchy of power relations affords
both macro and micro-analytical perspectives on the realisation of manipulation in
news translation in China.
Identification of the putative N-acetylglucosaminidase CseA associated with daughter cell separation in Tetragenococcus halophilus
Authors: Shirakawa Daichi , Wakinaka Takura , Watanabe Jun 
Published: May 2020

Abstract
The lactic acid bacterium Tetragenococcus halophilus, which is used as a starter to brew soy sauce, comprises both cluster-forming strains and dispersed strains. The cluster-forming strains are industrially useful for obtaining clear soy sauce, because the cell clusters are trapped by filter cloth when the soy sauce mash is pressed. However, the molecular mechanism underlying cell cluster formation is unknown. Whole genome sequence analysis and subsequent target sequence analysis revealed that the cluster-forming strains commonly have functional defects in N-acetylglucosaminidase CseA, a peptidoglycan hydrolase. CseA is a multimodular protein that harbors a GH73 domain and six peptidoglycan-binding LysM domains. Recombinant CseA hydrolyzed peptidoglycan and promoted cell separation. Functional analysis of truncated CseA derivatives revealed that the LysM domains play an important role in efficient peptidoglycan degradation and cell separation. Taken together, the results of this study identify CseA as a factor that greatly affects the cluster formation in T. halophilus.
