Abstract
Jupiter and Saturn each have complex systems of satellites and rings. These satellites can be classified into dynamical groups, implying similar formation scenarios. Recently, a larger number of additional irregular satellites have been discovered around both gas giants that have yet to be classified. The aim of this paper is to examine the relationships between the satellites and rings of the gas giants, using an analytical technique called cladistics. Cladistics is traditionally used to examine relationships between living organisms, the “tree of life.” In this work, we perform the first cladistical study of objects in a planetary science context. Our method uses the orbital, physical, and compositional characteristics of satellites to classify the objects in the Jovian and Saturnian systems. We find that the major relationships between the satellites in the two systems, such as families, as presented in previous studies, are broadly preserved. In addition, based on our analysis of the Jovian system, we identify a new retrograde irregular family, the Iocaste family, and suggest that the Phoebe family of the Saturnian system can be further divided into two subfamilies. We also propose that the Saturnian irregular families be renamed, to be consistent with the convention used in Jovian families. Using cladistics, we are also able to assign the new unclassified irregular satellites into families. Taken together, the results of this study demonstrate the potential use of the cladistical technique in the investigation of relationships between orbital bodies.
Dynamics of Intense Currents in the Solar Wind

Abstract
Transient currents in the solar wind are carried by various magnetic field discontinuities that contribute significantly to the magnetic field fluctuation spectrum. Internal instabilities and dynamics of these discontinuities are believed to be responsible for magnetic field energy dissipation and corresponding charged particle acceleration and heating. Accurate modeling of these phenomena requires detailed investigation of transient current formation and evolution. By examining such evolution using a unique data set compiled from observations of the same solar wind flow by two spacecraft at Earth’s and Mars’s orbits, we show that it consists of several processes: discontinuity thinning (decrease in thickness normalized by the ion inertial length), intensification of currents normalized to the proton thermal current (i.e., the product of proton charge, density, and thermal velocity), and increase in the compressional component of magnetic field variations across discontinuities. The significant proton temperature variation around most observed discontinuities indicates possible proton heating. Plasma velocity jumps across the discontinuities are well correlated with Alfvén velocity changes. We discuss possible explanations of the observed discontinuity evolution. We also compare the observed evolution with predictions of models describing discontinuity formation due to Alfvén wave steepening. Our results show that discontinuity modeling likely requires taking into account both the effects of nonlinear Alfvén wave dynamics and solar wind expansion.
Reliability assessment of a mechanism-based approach to post-injury knee magnetic resonance imaging interpretation by general radiologists
Authors: Stutterheim James , Goodier Matthew D. 
Published: May 2018

Background: A mechanism-based approach to post-injury knee magnetic resonance imaging (MRI) interpretation, following acute complex knee injury, is cited by several authors to provide increased reporting accuracy and efficiency, by allowing accurate prediction of injury to at-risk structures. This remains to our knowledge untested in a developing world setting and is of interest to us as South African general radiologists. Objective: To assess the reliability of a mechanism-based approach to complex post-trauma knee MRI interpretation when implemented by general radiologists in a South African setting, and compare our results with the findings of North American authors who compiled and assessed the same classification. To measure the agreement between the observers. Methods: A quantitative, observational, investigative, retrospective study was performed using a sample of 50 post-trauma knee MRI studies conducted at Grey’s Hospital, Pietermaritzburg. Two investigators independently applied the consolidated mechanism-based approach compiled by Hayes et al. as a research tool to interpret the knee MRI studies, blinded to each other’s findings. Results: Injury mechanism was assigned in 32% of cases by the principle investigator and in 20% of cases by the supervisor, with fair agreement between the observers (k = 0.39). The investigators agreed that 62% of cases were not classifiable by mechanism, 26% because of highly complex injury and 26% because of non-specific findings. Conclusion: Our findings indicate that the Hayes et al. classification is a non-ideal tool when used by general radiologists in our setting, as the pure injury mechanisms described in the classification were rare in our study group. Patient epidemiology and investigator experience are highlighted as potential limiting factors in this study. Despite this, we advocate that the concept of a mechanism-based approach for the interpretation of acute post-trauma knee MRI holds value for general radiologists, particularly in patients imaged before resolution of bone bruising (within 12–16 weeks of injury), and those injured in sporting and similar athletic activities.

AbstractThis secondary analysis quantified the psychometric properties of the Ohio Modified Arm–Motor Ability Test (OMAAT) in a sample of neurologically stable chronic stroke survivors (n = 67, 40 men; mean age 59.8 yr, standard deviation = 12.8; 42 White, 23 Black, 2 other; 92.5% right-sided lesion; 44 ischemic stroke). Findings indicate high OMAAT internal consistency (Cronbach’s α = .97, ordinal α = .98, Gugiu’s bootstrap reliability = .97), unidimensionality, and strong positive factor loadings for all 20 OMAAT items. Convergent validity between OMAAT and Action Research Arm Test total scores was strong (r = .90, p &lt; .0001). The OMAAT is the first short measure of upper extremity functional limitation available to clinicians and researchers that includes an administration manual and that has been examined using nonparametric psychometrics. A detailed administration manual is provided as a supplement to this article.
Lack of significant association between selected STAT3 polymorphisms and rheumatoid arthritis in the Polish population

Published: May 2018

ObjectivesRheumatoid arthritis (RA) is the most common systemic inflammatory disease and is of unknown etiology. The altered balance between immunosuppressive and inflammatory T cell subpopulations exerts a huge impact on RA pathogenesis. The STAT3 protein regulates genes involved in the immune responses. It regulates maturation of T and B cells. Its abnormal activity is significantly associated with autoimmune diseases and cancer development. We aimed to evaluate the contribution of three potentially functional single nucleotide polymorphisms (SNPs) within the STAT3 gene to susceptibility and severity of RA in the Polish population.Material and methodsA total of 595 patients with RA and 330 healthy individuals were included in the study. DNA from patients and healthy subjects was obtained from peripheral blood using standard DNA isolating methods. The STAT3 rs1053005, rs1026916 and rs2293152 polymorphisms were genotyped using the TaqMan SNP genotyping assay. The accuracy of SNP genotyping was confirmed using direct DNA sequence analysis.ResultsThe distribution of STAT3 polymorphisms did not differ significantly between cases and controls. Our results revealed a tendency only, where rs1026916 AA genotype occurred more frequently in RA patients compared to healthy controls, in codominant (p = 0.09), dominant (p = 0.06) and recessive (p = 0.09) models. STAT3 rs2293152 polymorphism was associated with higher DAS28 (p = 0.014 codominant model; p = 0.003 dominant model), increased number of swollen joints (p = 0.02), higher VAS (p = 0.01) and higher HAQ score (p = 0.05).ConclusionsWe did not observe a significant association between the three studied STAT3 genetic variants and increased susceptibility to or severity of RA. Only the STAT3 rs2293152 polymorphism was associated with parameters that indicate a more severe course of the disease. However, its distribution did not differ between RA and control groups. According to our observations these 3 studied STAT3 SNPs may not be used as risk factors for developing RA.

Published: May 2018

ObjectivesThe aim of our study was to determine a possible correlation between vertebral fractures (indicated by VFA – vertebral fracture assessment), TBS (trabecular bone score) and muscle strength (measured by means of handgrip strength test results) in a group of postmenopausal women.Material and methodsThe study was conducted between 2014 and 2015 in a group of patients of Krakow Medical Centre (KMC). Women who participated in the study were referred to KMC by an attending physician for suspected vertebral fracture. Apart from VFA, patients were additionally tested for bone density (including TBS), muscle strength (by means of a handgrip strength test) and height loss. Altogether 35 patients with an average age of 69.7 years (49–95, SD = 10.49) were included in the study.ResultsIn the group of 35 women, VFA analysis demonstrated vertebral fractures in 17 patients (40%). Vertebral height loss suggesting a fracture was revealed in 77 vertebrae. The mean result of the TBS was 1.195 (0.982–1.409, SD = 0.09), which suggests high risk of fracture. The majority of the subjects (65.7%) displayed major bone microarchitecture degradation (TBS < 1.23) and also the highest number of fractures (n = 62, 80.5% of all). There was no correlation between the spine bone mineral density (BMD) score and the TBS result, which confirms studies showing that subjects with the same bone density may have completely different TBS. Bone density (spine BMD) was similar (osteopenic) in groups with or without vertebral fracture (in VFA). We noted a significant correlation (r = 0.45, p < 0.05) between the number of fractured vertebrae and the handgrip score.ConclusionsVFA should be a part of a standard diagnostic procedure for patients with osteoporotic fractures. When it comes to identifying patients at risk of fracturing vertebrae, muscle strength (handgrip) may have potential use in clinical practice. The predictive value of the TBS in reference to vertebral fractures should be evaluated in bigger randomized studies.

Published: May 2018

The study aims at identifing the concept of strategic vision of the authorities in Zarqa University, identifing the most important elements, and proposing the appropriate mechanisms to meet the future challenges facing the university leader as a result of competition and how to maintain the teaching and non-teaching staff within the institution to enhance loyalty of the 'internal client ' in the future. Strategic vision variables were used; future status was determined, goals achieved by the vision were achieved, university culture was selected, and the appropriate strategy was chosen as independent variables affecting a dependent variable that is is the internal client relations management. The researchers collected the initial data of the study by means of a special questionnaire. The sample consists of (115) out of 300 faculty members at Zarqa University of various qualifications, ranks and experience.The results of the analysis show that there is a strong and significant effect on all elements of the strategic vision on internal client relationship management, and demographic variables (gender, age group, job title and years of experience) contributed intrinsically to the response of the sample regarding the adoption of the strategic vision factors in managing the internal client relations.Based on the findings of the study, the researchers proposed a number of recommendations to the administration of the university, focusing on spreading and supporting positive culture among faculty members, setting specific and clear objectives for the future to all university employees, along with constructing lucid future strategic directions, and updating the vision and mission of the institution. It is also recommended to comprehensively expand the study of the impact of strategic and other organizational factors; and programs and plans of management development on improving the management of relationships with the internal client of the University.
Une différence à inventer : l’américanité sauvage de Supervielle
Authors: Bernadet Arnaud 
Published: May 2018

L’expression de l’américanité chez Jules Supervielle est l’objet de plusieurs récidives littéraires. À mesure qu’il se dégage de l’influence romantique et parnassienne, encore prégnante dans Brumes du passé et Comme des voiliers, le poète apprend à « plier à son goût » la Muse uruguayenne. De Poèmes à Débarcadères, l’américanité se révèle plus encore inséparable d’une quête de l’identité. Elle traduit l’exigence d’une signature, capable enfin d’assigner à l’oeuvre ce que Supervielle appelle le « ton réel ». La question de la manière – cette mesure personnelle de l’écriture, conquise au terme des quatre premiers recueils – ne se distingue pas chez lui de la question de la culture, et réciproquement.
Practice Area Intentions of Graduates of Colleges of Osteopathic Medicine: What Role Does Debt Play?
Authors: Richards Jesse R. , Scheckel Caleb J. , Kunz Matt , Newman Jessica R. , Poole Kenneth G. , Mi Lanyu 
Published: May 2018

Abstract

Context
Enrollment in colleges of osteopathic medicine continues to increase, as does the need for physicians practicing in underserved areas. The cost of osteopathic medical education is substantial, with students often incurring debt of $200,000 or more. It is unclear whether practice patterns of new graduates will be affected by debt-to-income ratios.

Objective
To determine whether the intended practice location of graduates of colleges of osteopathic medicine is associated with medical education debt.

Methods
Using data from the American Association of Colleges of Osteopathic Medicine's annual survey to graduates of colleges of osteopathic medicine, the authors focused on graduates’ intention to practice in an underserved area, the amount of debt incurred, and plans to enter a loan-repayment program. Survey data from 2007, 2010, 2013, and 2016 were analyzed.

Results
From 2007 to 2016, the percentage of graduates who intended to practice in underserved areas increased (27.5% to 35.3%, respectively). Graduates with the most debt intended to practice in underserved areas at a higher percentage than those with the least amount of debt, and they also planned on using loan-repayment programs at a higher rate.

Conclusion
There is a strong association among the intention to practice in an underserved area, high debt load, and intention to use a loan-repayment program. Therefore, the osteopathic medical community should support increased access to loan-repayment programs to help its graduates surmount economic and social barriers to providing care in underserved areas.
Sorting nexin-1 is a candidate tumor suppressor and potential prognostic marker in gastric cancer

Published: May 2018

Sorting nexin-1 (SNX1) is an important functional protein in cell endocytosis, efflux, protein sorting, cell signal transduction, etc; however, the expression, the role and clinical relevance of SNX1 have not been investigated in gastric cancer (GC). In this study, we first performed a bioinformatics investigation using the data obtained from The Cancer Genome Atlas (TCGA) database. The result showed that SNX1 mRNA levels were significantly lower in GC tissues than in paracancerous tissues. In a study of 150 cases of GC, including 60 cases with paired paracancerous and cancer tissues and 90 cases with detailed follow-up information, SNX1 expression was analyzed by immunohistochemistry. Our study on paired paracancerous and cancer tissues showed that SNX1 protein expression remarkably decreased in GC tissues (50/60, 83.33%). A study on 90 patients with detailed follow-up information showed that tumors with higher SNX1 protein level were correlated with better clinicopathologic stages (p = 0.0285), nodal status (p = 0.0286), smaller tumor sizes (p = 0.0294) and a better survival rate in patients with GC (p = 0.0245). Univariate analysis of the 90 patients with GC showed that low-level SNX1 was significantly correlated with decreased overall survival of GC patients (p = 0.008), and associated with a relatively higher cumulative hazard of death. Exogenous expression of SNX1 inhibited the growth, migration, invasion and promoted the apoptosis and enhanced the sensitivity of GC cells to the chemotherapeutic drug 5-Fluorouracil (5-Fu) in vitro, while knockdown of SNX1 by short hairpin RNA (shRNA) significantly promoted the growth, migration, invasion and reduced the apoptosis and the sensitivity of GC cells to 5-Fu. SNX1 also showed to influence the levels of epithelial-mesenchymal transition markers including Vimentin, Snail, and E-cadherin in GC cells in vitro. Taken together, we propose here that SNX1 serves as a tumor suppressor and prognostic marker that reduces tumor cell malignancy for GC.
