Authors: Sun Ying , Wang Luxiao , Jiang Jiang , Wang Rong 
Published: November 2018

Enhanced interpersonal security has been shown to diminish the desire for money and possessions. In the present study, we focus on attachment security to examine the relationship between attachment security and materialism. By employing the experience in close relationships – short scale and material values scale, we observed a positive relationship between attachment insecurity and materialism in Study 1. In Study 2, we primed participants' feeling of attachment security to further explore the impact of attachment security on materialistic values. The results showed that participants in the security‐priming group exhibited lower levels of state materialism (Study 2a) and a longer time to respond to materialism‐related words (Studies 2b and 2c) than participants in the neutral condition. However, attachment styles did not moderate the attachment security‐materialism relationship. Our findings reveal that regardless of attachment style, boosting attachment security can effectively decrease materialism.

ABSTRACT

Primary hyperparathyroidism (PHPT) is a condition where elevated PTH levels lead to bone loss, in part through increased production of the osteoclastogenic factor IL-17A, by bone marrow (BM) T-helper 17 (Th17) cells, a subset of helper CD4+ T cells. In animals, PHPT is modeled by continuous PTH treatment (cPTH). In mice, an additional critical action of cPTH is the capacity to increase the production of RANKL by osteocytes. However, a definitive link between IL-17A and osteocytic expression of RANKL has not been made. Here we show that cPTH fails to induce cortical and trabecular bone loss and causes less intense bone resorption in conditional knock-out (IL-17RAΔOCY) male and female mice lacking the expression of IL-17A receptor (IL-17RA) in dentin matrix protein 1 (DMP1)-8kb-Cre–expressing cells, which include osteocytes and some osteoblasts. Therefore, direct IL-17RA signaling in osteoblasts/osteocytes is required for cPTH to exert its bone catabolic effects. In addition, in vivo, silencing of IL-17RA signaling in in DMP1-8kb–expressing cells blunts the capacity of cPTH to stimulate osteocytic RANKL production, indicating that cPTH augments osteocytic RANKL expression indirectly, via an IL-17A/IL-17RA–mediated mechanism. Thus, osteocytic production of RANKL and T cell production of IL-17A are both critical for the bone catabolic activity of cPTH. © 2018 American Society for Bone and Mineral Research.

AbstractFlight is an energetically costly form of transport imparting biomechanical stress that acts upon the wing bones. Previous studies have suggested that the cross‐sectional and microstructural features of wing bones may be adapted to resist biomechanical loads. During flight, however, each wing bone potentially experiences a unique loading regime. To assess possible differences among wing bones, we analyzed the microstructural features of the humerus, radius, ulna, and carpometacarpus (CMC) in eight griffon vultures (Gyps fulvus). Vascular canal orientation was evaluated in the diaphysis of the wing bones. Laminarity index (LI) was significantly different in the humerus versus CMC and ulna versus CMC. Results showed a lower proportion of circular vascular canals, due to resistance to torsional loads, in CMC than in humerus and ulna. The midshaft cross‐section revealed an elliptical shape in the CMC compared to the circular shape observed in the other wing bones, with a maximum second moment of inertia (Imax) orientation which suggests a capacity to withstand bending loads in a dorsoventral direction. The volumetric bone mineral density in the diaphysis was statistically different in CMC compared to the other bones analyzed. Its lower mineral density may reflect an adaptation to a different type and load of stresses in CMC compared to the proximal wing bones. No significant difference was found in the relative cortical area (CA/TA) among the four elements, while the polar moment of area J (Length‐standardized) revealed a higher resistance to torsional load in the humerus than in the other bones. Our results would seem to indicate that griffon wing bones are structured as an adaptation, represented by two segments that respond to force in two ways: the proximal segment is specially adapted to resist torsional loads, whereas the distal one is adapted to resist bending loads.
Capsular‐defective Porphyromonas gingivalis mutant strains induce less alveolar bone resorption than W50 wild‐type strain due to a decreased Th1/Th17 immune response and less osteoclast activity

AbstractBackgroundEncapsulation of Porphyromonas gingivalis has been demonstrated as responsible of several host immunological changes, which have been associated with the pathogenesis of periodontitis. Using a murine model of periodontitis and two isogenic non‐capsulated mutants of P. gingivalis, this study aimed to analyze whether P. gingivalis encapsulation induces more severe alveolar bone resorption, and whether this bone loss is associated with a T‐helper (Th)1 and Th17‐pattern of immune response.MethodsExperimental periodontal infections were generated by oral inoculation with the encapsulated W50 wild‐type strain or isogenic non‐encapsulated ΔPG0116‐PG0120 (GPA) and ΔPG0109‐PG0118 (GPC) mutants of P. gingivalis. Periodontal infections induced with the encapsulated HG184 or non‐encapsulated ATCC 33277 strains of P. gingivalis were used as controls. Alveolar bone resorption was analyzed using microcomputed tomography and scanning electron microscopy. The expression levels of Th1, Th2, Th17, or T regulatory‐associated cytokines and RANKL, as well as the periodontal bacterial load, were quantified by quantitative polymerase chain reaction. The detection of Th1 and Th17 lymphocytes was analyzed by flow cytometry.ResultsIn the periodontal lesions, both capsular‐defective knockout mutant strains of P. gingivalis induced less alveolar bone resorption than the encapsulated W50 wild‐type strain. This decreased bone loss was associated with a dismissed RANKL expression, decreased Th1‐ and Th17‐type of cytokine expression, reduced Th1 and Th17 lymphocyte detection, and low osteoclast finding.ConclusionThese data demonstrate that encapsulation of P. gingivalis plays a key role in the alveolar bone resorption induced during periodontitis, and this bone loss is associated with a Th1‐ and Th17‐pattern of immune response triggered in the periodontal lesions.

AbstractBackgroundThe aim of this study was to investigate how different patient‐related risk indicators might be associated with the odds of developing subclinical periodontitis in adolescents.MethodsThis cross‐sectional study included 252 Finnish individuals aged 15 to 16 years, of whom 141 were boys and 111 girls. A specially trained dentist performed clinical examinations: measurements included periodontal indexes (bleeding on probing, visible plaque index, root calculus, and probing depth, smoking by pack‐years, periodontal bacteria (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Prevotella intermedia, Prevotella nigrescens, and Treponema denticola) and the potential salivary periodontal biomarkers (active matrix metalloproteinase‐8 [aMMP‐8], polymorphonuclear leukocyte elastase [PMN elastase], and total protein, albumin, immunoglobulin A, immunoglobulin G, and immunoglobulin M). Results were analyzed by ordinal logistic regression, one‐way analysis of variance, Fisher exact test, and Kruskal‒Wallis H test.ResultsThe main finding of this study was that subclinical periodontitis in adolescents was statistically significantly associated with elevated salivary aMMP‐8 but not with PMN elastase. Also, adolescents with subclinical periodontitis had statistically significantly higher levels of bleeding on probing, root calculus, and dental plaque than adolescents without subclinical periodontitis.ConclusionsWe suggest that the main risk factor for subclinical periodontitis in adolescents is the partly calcified, dysbiotic bacterial biofilm, which interacts with the immune defenses of the host; this leads to gingival inflammation and eventually to deepening periodontal pockets. This proinflammatory subclinical periodontitis stage, which represents stage I periodontitis in the new classification, is reflected as elevated salivary aMMP‐8 levels in oral fluids.

AbstractWe present accurate measurements for the wavenumbers of the S0(0), S0(1), and S0(2) pure rotational Raman lines in D2. Our measurements improve the accuracy of the previously available experimental data by an order of magnitude. They also show complete agreement with the state‐of‐the‐art ab initio calculations of the D2 rotational splitting, which include both relativistic and Quantum electrodynamics (QED) corrections.
Tumor cell seeding in the biopsy tract and its clinical significance in osteosarcomas
Authors: Turkoz Kemal H. , Erol Bulent , Seven Ipek E. 
Published: November 2018

Background and objectivesThe reasons behind the removal of the biopsy tract in osteosarcomas are not well known, and studies about tumor seeding in the biopsy tract have generated conflicting results. This study is designed to evaluate the presence and possible clinical significance of tumor cell seeding in the biopsy tract of osteosarcomas.MethodsWe prospectively evaluated 55 cases of osteosarcomas for tumor cell seeding and other clinical and pathologic prognostic parameters.ResultsEleven cases (20%) involved microscopic tumor foci in the biopsy tract. The higher local recurrence rates (P = 0.005) and worse recurrence‐free survivals (
P = 0.009) were observed in patients with tumor cell foci in the biopsy tract. Mitotic rate, tumor cell pleomorphism, and matrix production in main tumor foci were higher in cases with tumor seeding (
P = 0.047,
P = 0.012, and
P = 0.005, respectively)ConclusionsTumor seeding in the biopsy tract is a fact in osteosarcomas. The higher local recurrence rates are more likely to occur in cases with tumor seeding.

BackgroundDespite surgery, many patients experience locoregional recurrence (LR), the optimum treatment of which is still debated.MethodsAll 297 consecutive patients operated for a nonmetastatic primary retroperitoneal soft tissue sarcoma (RPS) between 1994 and 2017 were retrospectively analyzed to report our experience in treating LR.ResultsAfter a median follow‐up of 97 months, 55 patients (19%) developed LR. The first site of recurrence was locoregional in 100% with associated peritoneal metastases in 45% and distant metastases in 5%. After LR treatment, the 1‐, 3‐, and 5‐year overall survival (OS) rates were 71%, 46%, and 33%. Low tumor grade, disease‐free interval above 24 months, exclusive LR, and well‐differentiated liposarcoma were predictive of better OS. The treatment strategy (best supportive care, chemotherapy radiotherapy, and/or surgery) was not statistically significant. Fourteen patients underwent initial surveillance (strategic delay) for low‐grade LR and eventually required treatment in 86% after a median delay of 20 months during which no patient developed distant metastases.ConclusionsThe management of LR in RPS is complex. An initial surveillance may not alter survival in asymptomatic low‐grade and slow‐growing LR. An LR decision scheme is proposed.
Guidelines for tuning the macropore structure of monolithic columns for high‐performance liquid chromatography
Authors: Dores‐Sousa José Luís , Fernández‐Pumarega Alejandro , De Vos Jelle , Lämmerhofer Michael , Desmet Gert , Eeltink Sebastiaan 
Published: November 2018

AbstractThe ability to control the external porosity and to tune the dimensions of the macropore size on multiple length scales provides the possibility of tailoring the monolithic support structure towards separation performance. This paper discusses the properties of conventional polymer–monolithic stationary phases and its limitations regarding the effects of morphology on kinetic performance. Furthermore, guidelines to improve the macropore structure are discussed. The optimal monolithic macropore structure is characterized by high external porosity (while maintaining ultra‐high‐pressure stability), high structure homogeneity, polymer globule clusters in the submicron range, and macropores with a diameter tuned toward speed (small diameter in the 100–500 nm range using short beds) or efficiency (larger macropores in the range of 500 nm–1 μm allowing the use of longer column formats). Finally, promising approaches to control the morphology are discussed.
Posttraumatic Stress Disorder in Patients With Borderline Personality Disorder: Treatment Outcomes and Mediators
Authors: Barnicot Kirsten , Crawford Mike 
Published: November 2018

AbstractPosttraumatic stress disorder (PTSD) is highly comorbid with personality disorder (PD). We evaluated whether comorbid PTSD has a negative effect on patients’ ability to benefit from evidence‐based psychological treatments for PD and tested potential mediators of any effect. The effect of PTSD on self‐harm and borderline PD symptoms was evaluated in 90 patients with borderline PD who were receiving dialectical behavior therapy or mentalization‐based therapy. Self‐report and interview measures were administered every 3 months over a 12‐month period. Three‐quarters of participants met criteria for PTSD. In the 12 months after beginning treatment, participants with PTSD did not engage in self‐harm more often or present with more severe borderline PD symptoms. However, a higher level of PTSD symptom severity at baseline was associated with more frequent self‐harm during follow‐up, incidence rate ratio = 1.03, 95% CI [1.01, 1.06], p = .005. Participants whose PTSD did not improve or worsened were more likely to still self‐harm, odds ratio (OR) = 0.91, 95 % CI [0.85, 0.97], p = .004, and report more severe borderline PD symptoms, b = 0.53, 95% CI [0.34, 0.73], p < .001, at the end of 12 months. The negative effects of PTSD symptoms remained significant after adjusting for potential confounders and were partially mediated by high ongoing levels of emotional dysregulation, indirect effect b = 0.32, 95% CI [0.19, 0.50]. These findings identify subgroups at risk of poorer outcomes from evidence‐based psychological treatments for PD and support the idea that treating PTSD may improve outcomes.
Ignoring heat inertia impairs accuracy of determination of activation energy in thermal analysis
Authors: Šesták Jaroslav 
Published: November 2018

AbstractThis paper critically analyzes the traditional method of kinetic determination of activation energy by sectioning the recorded differential thermal analysis peak area. This procedure is incorrect because it misses the impact of thermal inertia, which changes the shape of the peak's base line from straight to s‐shape. This effect has been known since the Newton cooling law, but the resulting errors persist to be interwoven into all the kinetic methods based on nonisothermal thermoanalytical measurements. Relating to calorimetry, it is necessary here because heat inertia has become a standard part of heat determination via using the Tian historical equation. The role and impact of heat inertia is discussed and analyzed in detail.
Identifying (our) donors: Toward a social psychological understanding of charity selection in Australia
Authors: Chapman Cassandra M. , Louis Winnifred R. , Masser Barbara M. 
Published: November 2018

AbstractGender, age, religiosity, and political orientation are often associated with a propensity to give to charity. However, these broad associations mask inconsistencies that are not yet understood. Just as identity plays an important role in shaping consumer choices generally, donors’ identities could explain diverging associations between demographic social categories and the types of charities supported. Two studies, with confirmed workplace giving donors (N = 675) and a community sample of self‐reported donors (N = 376) in Australia, provide evidence that associations significantly vary across categories of charity. Specifically, older donors are more likely to support religious and health charities; religious donors are more likely to support religious, welfare, and international organizations, but less likely to support animal charities; and politically conservative donors are less likely than liberal donors to donate to international organizations. The findings are interpreted through the lens of identity, with a focus on how group priorities and relevant norms may affect charity selection. The results have implications for nonprofit marketing practice, including targeting, channel selection, and framing of fundraising appeals.
Quantitative insights from online qualitative data: An example from the health care sector
Authors: Pitt Christine , Mulvey Michael , Kietzmann Jan 
Published: November 2018

AbstractAmong the deluge of online data generated by users in the form of text on social media sites, health care reviews are among the most common, and potentially, the most insightful. Patients review and comment on the experiences with procedures as varied as hysterectomies, colonoscopies, and chemotherapy. In their attempts to reduce the uncertainty associated with medical treatments, many patients nowadays also turn to social media, where they rely on the experiences articulated by other patients. In this study, IBM Watson is used to examine how knee replacement patients talk about their emotions and express sentiment through their comments online. Then, a latent class cluster modeling procedure is used to segment these patients into distinct groups, according to their emotions (anger, disgust, fear, happiness, sadness, and surprise), sentiment, and their overall satisfaction with knee replacement surgery. The findings show how qualitative online data can be transformed into quantitative insights regarding underlying market segments, which could then be targeted through different strategies by both marketers and health care practitioners.
Numerical determination of the effective permeability coefficient of soil–rock mixtures using the numerical manifold method
Authors: Chen Tao , Yang Yongtao , Zheng Hong , Wu Zhijun 
Published: November 2018

SummaryThe present study extends the numerical manifold method to investigate the effective permeability coefficient (keff) of soil–rock mixtures. The influence of rock content, rock size, rock shape, and rock blocks' major axis direction on keff is studied. The results show the following: (1) keff decreases as the rock content increases; (2) the influence of rock size on keff can be neglected if other parameters are fixed; (3) the values of keff are nearly the same if rock blocks are in circular or regular hexagon shapes; and (4) the major axis direction of rock blocks has some influence on keff.
A novel efficient mixed formulation for strain‐gradient models
Authors: Papanicolopulos Stefanos‐Aldo , Gulib Fahad , Marinelli Aikaterini 
Published: November 2018

SummaryVarious finite elements based on mixed formulations have been proposed for the solution of boundary value problems involving strain‐gradient models. The relevant literature, however, does not provide details on some important theoretical aspects of these elements. In this work, we first present the existing elements within a novel, single mathematical framework, identifying some theoretical issues common to all of them that affect their robustness and numerical efficiency. We then proceed to develop a new family of mixed elements that addresses these issues while being simpler and computationally cheaper. The behavior of the new elements is further demonstrated through two numerical examples.
Permittivity mapping in the VLF–LF range using a multi‐frequency EMI device: first tests in archaeological prospection
Authors: Simon Fançois‐Xavier , Tabbagh Alain , Donati Jamieson C. , Sarris Apostolos 
Published: November 2018

ABSTRACTIn the early years of near‐surface geophysical applications, measurements obtained using electromagnetic induction (Slingram or dipole–dipole) instruments were first interpreted in terms of electrical conductivity. Afterwards, studies began considering the importance of magnetic susceptibility. Until now, however, no attention has been paid to possible responses in dielectric permittivity. After reviewing the current state of knowledge regarding the expected theoretical responses in the very low frequency to low frequency (VLF‐LF) range (3–300 kHz) and the value range of this property for soils, we propose the use of multi‐frequency instruments to define a process allowing for the determination of the apparent conductivity and permittivity in the higher part of the frequency range above 20 kHz. We test this process through a series of experiments at archaeological sites in Greece using the GEM‐2 (Geophex Ltd) instrument. In our experiments, the soil permittivity values fall between several hundredths and several thousandths. The results indicate lateral variations different from the other properties with a significant influence of the stone content and of the ionic strength, while a decrease with frequency may also provide further information on soil dielectric behaviours.
Robust H∞fuzzy control design for dithered nonlinear large‐scale systems with multiple time delays
Authors: Hsiao Feng‐Hsiag 
Published: November 2018

SummaryA novel approach is proposed in this study to stabilize nonlinear multiple time‐delay (NMTD) large‐scale systems via a composite of fuzzy controllers and dithers. Moreover, a delay‐dependent stability criterion is derived from Lyapunov's direct method. According to this criterion and the decentralized control scheme, a set of model‐based fuzzy controllers is synthesized to stabilize the NMTD large‐scale system and the H∞ control performance is achieved at the same time. If the designed fuzzy controllers cannot stabilize the NMTD large‐scale system, a set of dithers (as the auxiliaries of fuzzy controllers) is simultaneously introduced to stabilize the NMTD large‐scale system. Finally, a numerical example with simulations is provided to illustrate the concepts discussed throughout this paper.
