Effect of extracting process on saponin content and antioxidant activity of Gleditschia fera (Lour.) Merr dried fruit extract
Authors: Anh Trieu Tuan , Thanh Huyen Nguyen Thi , Lam Tri Duc 
Published: July 2019

Abstract
Gleditschia fera (Lour.) Merr (GfL) was a traditional herbal used for treatment of diabetes mellitus and for arresting and/or slowing down hair loss. In this study, powder of GfL dried fruit was immersed in the pure water to extract saponin and other components atdifferent material/solvent ratios, extraction time (hours) and extraction temperature (°C). Saponin content of the final product (extract) was evaluated by Oleanolic acid-H2SO4 assay. The antioxidants activity of the extract was determined by DPPH method. High extraction yield (74g/100 g) was obtained at the material/solvent ratio 1:15 (w/v), 50°C and 4 hours extraction time. Under these optimized conditions, the highest saponin content of was 37.06 mg/g. The extract can harvest 45.30 % of DPPH at 10000 μg/ml concentration

Authors: Jin C Y , Li Y Q , Zhu J C , Li Y 
Published: July 2019

Abstract
In order to analyze the compressive performance of ECC with PVA by finite element method, in this paper the three-dimensional distribution model of PVA fiber was established by compiling the random sequence program of Matlab considering the random distribution of PVA in matrix ECC. On this basis, the finite element model of ECC was established by ABAQUS software to study the stress and deformation properties of ECC with different PVA fiber content under axial compression.
A Design Method of Chaotic Synchronous Multi-stable Manifold
Authors: Zuo Z L , Yu X 
Published: July 2019

Abstract
Line spectra in the low frequency band of the underwater radiated noise are the main factors affecting the acoustic stealth performance of submarines. The chaotification technique for line spectra reduction can realize spectra reconstruction and reduce line spectra intensity by converting line spectra in the low frequency band into chaotic spectra in the broadband frequency. Previous studies have shown that the method of the generalized synchronization of chaos can generate continuous chaos of the system under variable operating conditions, and can reduce the amplitude significantly in some cases, which provides a new idea for the theory of the chaotification technique for line spectra reduction. However, this method can only select the appropriate synchronization control strategy of chaos through “trial and error” method to achieve chaos with small amplitude. Therefore, a design method of multiple stable synchronous manifolds including stable chaotic attractors with small amplitude is proposed. This method is verified and illustrated by the coupled Duffing system, and applied to the two degree-of-freedom (DOF) nonlinear vibration isolation system(VIS).

Abstract
The Oxford WebQ is an online 24-hour dietary questionnaire that is appropriate for repeated administration in large-scale prospective studies, including the UK Biobank study and the Million Women Study. We compared the performance of the Oxford WebQ and a traditional interviewer-administered multiple-pass 24-hour dietary recall against biomarkers for protein, potassium, and total sugar intake and total energy expenditure estimated by accelerometry. We recruited 160 participants in London, United Kingdom, between 2014 and 2016 and measured their biomarker levels at 3 nonconsecutive time points. The measurement error model simultaneously compared all 3 methods. Attenuation factors for protein, potassium, total sugar, and total energy intakes estimated as the mean of 2 applications of the Oxford WebQ were 0.37, 0.42, 0.45, and 0.31, respectively, with performance improving incrementally for the mean of more measures. Correlation between the mean value from 2 Oxford WebQs and estimated true intakes, reflecting attenuation when intake is categorized or ranked, was 0.47, 0.39, 0.40, and 0.38, respectively, also improving with repeated administration. These correlations were similar to those of the more administratively burdensome interviewer-based recall. Using objective biomarkers as the standard, the Oxford WebQ performs well across key nutrients in comparison with more administratively burdensome interviewer-based 24-hour recalls. Attenuation improves when the average value is taken over repeated administrations, reducing measurement error bias in assessment of diet-disease associations.
QuanTest2: benchmarking multiple sequence alignments using secondary structure prediction
Authors: Sievers Fabian , Higgins Desmond G 
Published: July 2019

AbstractMotivationSecondary structure prediction accuracy (SSPA) in the QuanTest benchmark can be used to measure accuracy of a multiple sequence alignment. SSPA correlates well with the sum-of-pairs score, if the results are averaged over many alignments but not on an alignment-by-alignment basis. This is due to a sub-optimal selection of reference and non-reference sequences in QuanTest.ResultsWe develop an improved strategy for selecting reference and non-reference sequences for a new benchmark, QuanTest2. In QuanTest2, SSPA and SP correlate better on an alignment-by-alignment basis than in QuanTest. Guide-trees for QuanTest2 are more balanced with respect to reference sequences than in QuanTest. QuanTest2 scores correlate well with other well-established benchmarks.Availability and implementationQuanTest2 is available at http://bioinf.ucd.ie/quantest2.tar, comprises of reference and non-reference sequence sets and a scoring script.Supplementary informationSupplementary data are available at Bioinformatics online
Transcervical mediastinoscopy in patients with a permanent tracheostomy: is it feasible?
Authors: Cansever Levent , Seyrek Yunus , Kutluk Ali Cevat , Akin Hasan , Kocaturk Celalettin Ibrahim , Bedirhan Mehmet Ali 
Published: July 2019

Abstract

OBJECTIVES
Cervical mediastinoscopy may become essential in patients with pathological lymph nodes at mediastinum after laryngectomy. However, having had a previous tracheostomy has been reported to be a contraindication for cervical mediastinoscopy.

METHODS
Between January 2010 and December 2017, cervical mediastinoscopy was performed for lung cancer staging in 1985 patients at the Department of Thoracic Surgery, Yedikule Chest Diseases and Thoracic Surgery Education and Research Hospital, Istanbul, Turkey. Eighteen of these patients (1%) had a permanent tracheostomy after total laryngectomy and cervical radiotherapy due to laryngeal carcinoma.

RESULTS
Cervical mediastinoscopy was performed in 18 patients with a permanent tracheostomy after total laryngectomy. The negative predictive value of cervical mediastinoscopy was 13/14 (93%). The average operative time was 63 min (SD 12.0, range 50–90 min). The negative predictive value of endobronchial ultrasonography was 4/7 (57%). Positron emission tomography–computed tomography had a positive predictive value of 3/15 (20%) and a negative predictive value of 2/3 (67%).

CONCLUSIONS
Contrary to the claims of 2 textbooks, cervical mediastinoscopy is a viable method for patients with a tracheostomy after laryngectomy. The negative predictive values of standard cervical mediastinoscopy and mediastinoscopy for patients with a tracheostomy after total laryngectomy are approximately equivalent. Our results indicate that cervical mediastinoscopy is a feasible method in patients with a permanent tracheostomy when applied by experienced thoracic surgeons in specialized hospitals.
Spectrality of Polytopes and Equidecomposability by Translations
Authors: Lev Nir , Liu Bochen 
Published: July 2019

Abstract
Let $A$ be a polytope in ${\mathbb{R}}^d$ (not necessarily convex or connected). We say that $A$ is spectral if the space $L^2(A)$ has an orthogonal basis consisting of exponential functions. A result due to Kolountzakis and Papadimitrakis (2002) asserts that if $A$ is a spectral polytope, then the total area of the $(d-1)$-dimensional faces of $A$ on which the outward normal is pointing at a given direction, must coincide with the total area of those $(d-1)$-dimensional faces on which the outward normal is pointing at the opposite direction. In this paper, we prove an extension of this result to faces of all dimensions between $1$ and $d-1$. As a consequence we obtain that any spectral polytope $A$ can be dissected into a finite number of smaller polytopes, which can be rearranged using translations to form a cube.
Rebuilding Life after Burn Injuries in Korea: Using Photovoice
Authors: Kim Kyung Mee , Ban Mi So 
Published: July 2019

Abstract
This study analyzed life after injury for burn survivors using the photovoice research method. Study participants were six burn survivors who lived in the community after being discharged from the hospital. These six participants engaged in a series of photovoice workshops and activities that took place over a period of 4 months. The study results were as follows: burn survivors were able to achieve a positive body image during their physical recovery. They overcame many psychological difficulties that accompanied their burn injuries. Their attitudes toward their lives changed positively. The greatest influence in bringing out these changes was support from family, friends, and other burn survivors. They were better able to fight against social oppression with their recovered self-esteem. The participants had experienced a disconnect from the activities and interpersonal relationships they had prior to their injury owing to long-term hospital stays and time away from work. However, as they began new social activities, they were able to establish new interpersonal relationships. Based on the research results, this study suggests that medical, psychological, and social approaches as well as positive changes in social attitude are necessary to support burn survivors’ recovery.

Abstract
We report the discovery of WASP-166b, a super-Neptune planet with a mass of 0.1 MJup (1.9 MNep) and a bloated radius of 0.63 RJup. It transits a V = 9.36, F9V star in a 5.44-d orbit that is aligned with the stellar rotation axis (sky-projected obliquity angle λ = 3 ± 5 deg). Variations in the radial-velocity measurements are likely the result of magnetic activity over a 12-d stellar rotation period. WASP-166b appears to be a rare object within the ‘Neptune desert’.
Remembering John Steele and his models for understanding the structure and function of marine ecosystems
Authors: Anderson Thomas R , Gentleman Wendy C 
Published: July 2019

AbstractJohn Steele (1926–2013) is remembered for his ecosystem modelling studies on the role of biological interactions and environment on the structure and function of marine ecosystems, including consequences for fish production and fisheries management. Here, we provide a scientific tribute to Steele focusing on, by means of example, his modelling of plankton predation [Steele and Henderson (1992) The role of predation in plankton models. J. Plankton Res., 14, 157–172] that showed that differences in ecosystem dynamics between the subarctic Pacific and North Atlantic oceans can be explained solely on the basis of zooplankton mortality. The study highlights Steele’s artistry in simplifying the system to a tractable minimal model while paying great attention to the precise functional forms used to parameterize mortality, grazing and other biological processes. The success of this and other works by Steele was in large part due to his effective communication with the rest of the scientific community (especially non-modellers) resulting from his enthusiasm, use of an experiment-like (hypothesis driven) approach to applying his models and by describing simplifications and assumptions in scrupulous detail. We also intend our contribution to remember Steele as the consummate gentleman, notably his humble, behind-the-scenes attitude, his humour and his dedication to enhancing the careers of others.
12Modern European Philosophy
Authors: Tomlinson George 
Published: July 2019

AbstractThis chapter reviews four books published in 2018 which are not readily categorized as works in ‘modern European philosophy’: Gurminder K. Bhambra, Kerem Nişancloğlu, and Dalia Gebrial’s edited volume Decolonising the University, Chantal Mouffe’s For a Left Populism, Cinzia Arruzza, Tithi Bhattacharya, and Nancy Fraser’s Feminism for the 99%, and Andreas Malm’s The Progress of this Storm. Yet their uneasy relationship to this philosophy is precisely the reason they constitute a significant contribution to it. The philosophical originality and critical purchase of these books proceed from the fact that each is a singular case of philosophy’s dependence on ‘non-philosophy’; each exposes the impossibility of viewing philosophy as a self-sufficient discipline. In particular, they are a timely reminder that the best political philosophy is produced through actually existing social movements to change (which ecologically now means simply saving) the world. The chapter is divided into six sections: 1. Introduction; 2. Decolonizing Philosophy: Decolonising the University; 3. Anti-Post-Politics: For a Left Populism; 4. Anti-Post-Marxism: Feminism for the 99%; 5. Anti-Postmodernism: The Progress of This Storm; 6. Conclusion.
Better Patient-Reported Experiences with Health Care Are Associated with Improved Clinical Outcome after Carpal Tunnel Release Surgery
Authors: Schrier Verena J. M. M. , Poelstra Ralph , Selles Ruud W. , Slijper Harm P. , Amadio Peter C. , Hovius Steven E. R. , Porsius Jarry T. 
Published: July 2019

Background:
In hand surgery, and specifically carpal tunnel syndrome, it is currently unknown whether experiences with health care influence surgical outcome. To investigate whether there is an association between patient-reported experience measures and symptom relief, data were gathered using a cohort of patients undergoing surgical treatment for carpal tunnel syndrome.

Methods:
Patient-reported experience measures and patient-reported outcome measures were registered in a national database of 16 hand surgery practices. The experience measure data were gathered at 3 months after surgery and included six subscales on different health care delivery aspects (e.g., provided information, communication, facility, operative care). The outcome measure data were acquired before and 3 months after surgery with the Boston Carpal Tunnel Assessment Questionnaire. The association was tested using linear regression analyses.

Results:
A total of 1607 patients were included in the analysis. The experience measure scores were good to excellent, with a median value between 8.0 and 8.5 on a 10-point scale. Regression analyses showed a significant (p < 0.001) association with the Boston Carpal Tunnel Assessment Questionnaire for all individual patient-reported experience measure subscales. The greatest effects were found in physician communication and treatment information. Patient-reported experience measures accounted for more than 5 percent of the explained variance, with patient characteristics explaining an approximately additional 3 percent.

Conclusions:
In this large data set of carpal tunnel syndrome patients who underwent surgical release, a significant impact of health care experiences on self-reported clinical outcome was found. This is relevant information, not only for directing care providers in improving health care experiences as a quality-of–health care measure but now also potentially to achieve better clinical outcome.

Published: July 2019

Learning Objectives:
After studying this article, the participant should be able to: 1. Process several patient-specific factors before reaching an optimal treatment strategy with appreciation for facial balance. 2. Define the advantages and disadvantages of various hyaluronic acid preparations and delivery techniques, to achieve a specific goal. 3. Perform advanced facial rejuvenation techniques adapted to each facial zone, combining safety considerations. 4. Prevent and treat complications caused by inadvertent intraarterial injections of hyaluronic acid.

Summary:
The growing sophistication and diversity of modern hyaluronic acid fillers combined with an increased understanding of various delivery techniques has allowed injectable filler rejuvenation to become a customizable instrument offering a variety of different ways to improve the face: volume restoration, contouring, balancing, and feature positioning/shaping—beyond simply fading skin creases. As more advanced applications for hyaluronic acid facial rejuvenation are incorporated into practice, an increased understanding of injection anatomy is important to optimize patient safety.
Protective Effect of Extract of Ginkgo biloba 761 against Frostbite Injury in Rats
Authors: Aizawa Tetsushi , Kuwabara Masahiro , Kubo Satoshi , Aoki Shimpo , Azuma Ryuichi , Kiyosawa Tomoharu 
Published: July 2019

Background:
When frostbite thaws, reperfusion injury has a crucial impact on tissue injury, and production of free radicals induces further tissue damage. This study examined whether extract of Ginkgo biloba 761 could ameliorate frostbite injury as a free radical scavenger.

Methods:
Seventy-five Fisher 344 rats were divided into five groups of 15, and frostbite injury was created in each animal by sandwiching the left hind foot between a frozen magnet (−78.5°C) and a room-temperature magnet. Group I received saline; groups II, III, and IV received extract of Ginkgo biloba 761 (200, 100, and 50 mg/kg, respectively); and group V received superoxide dismutase (12 mg/kg). All drugs were injected intraperitoneally three times at 24-hour intervals. The wound surface area was measured throughout the wound healing period. Wounds were also harvested at various times to count cells stained by monoclonal antibodies for 4-hydroxy-2-nonenal and 8-hydroxy-2′-deoxyguanosine.

Results:
Compared to group I, the wound surface area was significantly smaller in groups II and III on days 1 and 3 after wound creation. Histologic examination revealed significantly more 4-hydroxy-2-nonenal–stained cells and 8-hydroxy-2′-deoxyguanosine–stained cells in group I compared to other groups on day 1. However, there was no difference in the total healing period among the groups. A higher dose test of extract of Ginkgo biloba 761 (300 mg/kg daily) induced animal death, probably because of toxicity.

Conclusion:
Extract of Ginkgo biloba 761 demonstrated a protective effect against frostbite in the present model and probably alleviated reperfusion injury by reducing tissue peroxidation.
Risk Factors for Perioperative Respiratory Failure following Mandibular Distraction Osteogenesis for Micrognathia: A Retrospective Cohort Study
Authors: Zhang Rosaline S. , Lin Lawrence O. , Hoppe Ian C. , Bartlett Scott P. , Taylor Jesse A. , Swanson Jordan W. 
Published: July 2019

Background:
The frequency of respiratory events in the perioperative period, and optimal duration of intubation during early mandibular distraction osteogenesis activation, are poorly understood. This study assesses potential risk factors associated with perioperative respiratory events, particularly the need for reintubation, following mandibular distraction osteogenesis surgery.

Methods:
A retrospective review was conducted for infants (younger than 1 year) undergoing mandibular distraction osteogenesis for tongue-based airway obstruction between November of 2010 and December of 2017. Univariate and multivariate analyses of sentinel events and outcomes were performed.

Results:
Ninety infants (median age, 35 days) were included (50 percent were syndromic). Twenty-seven subjects (30 percent) experienced a respiratory event requiring intervention before discharge, including 14 subjects who failed initial extubation. Subjects extubated earlier than postoperative day 5 failed extubation more frequently (33%) compared to those extubated later (9%; p = 0.005). Respiratory events occurred more frequently when extubation was attempted at distraction lengths of 5 mm or less (42 percent) compared to greater than 5 mm (21 percent; p = 0.032). Logistic regression modeling showed that syndromic status (OR, 14.8) and secondary airway anomaly (OR, 6.1) were significant predictors for respiratory events, whereas greater length of distraction at the time of extubation was protective (OR, 0.8; p < 0.05).

Conclusions:
Postoperative intubation of at least 5 days with associated mean distraction of 5 mm appears to be associated with successful extubation trial following mandibular distraction osteogenesis surgery. Patients with congenital syndromes and secondary airway anomalies are more likely to experience perioperative respiratory events.

Tissue-Based Planning and Technique for Breast Augmentation with Anatomical Implants
Authors: Adams William P. , Afrooz Paul N. , Stuzin James M. 
Published: July 2019

Summary:
Breast augmentation with anatomical implants offers several potential advantages. Tissue-based planning is patient specific and essential in choosing the correct dimensions of an implant, thereby providing greater control in breast shape following augmentation. This video vignette demonstrates tissue-based planning in a patient with a constricted breast, allowing the surgeon to accurately choose the proper implant dimensions, which correct the constriction while providing aesthetic control of breast shape. Operative techniques of precise pocket formation, prospective hemostasis, and judging the aesthetic contour following implant insertion are demonstrated.

Authors: Thielecke Lars , Cornils Kerstin , Glauche Ingmar 
Published: July 2019

AbstractMotivationGenetic barcodes have been established as an efficient method to trace clonal progeny of uniquely labeled cells by introducing artificial genetic sequences into the corresponding genomes. The assessment of those sequences, relies on next generation sequencing and the subsequent analysis aiming to identify sequences of interest and correctly quantifying their abundance.ResultsWe developed thegenBaRcodepackage as a toolbox combining the flexibility of digesting next generation sequencing reads with or without a sophisticated barcode structure, with a variety of error correction approaches and the availability of several types of visualization routines. Furthermore, a graphical user interface was incorporated to allow also less experienced R users package-based analyses. Finally, the provided tool is intended to bridge the gap between generating and analyzing barcode data and thereby supporting the establishment of standardized and reproducible analysis strategies.AvailabilityThegenBaRcodepackage is available at CRAN (https://cran.r-project.org/pack-age=genBaRcode).Contactlars.thielecke@tu-dresden.de
