Study Design: Retrospective cohort. Objectives: Parkinson’s disease (PD) is a neurodegenerative condition associated with significant morbidity and mortality. PD patients often develop spinal conditions and are known to have high complication rates following surgery. This study evaluated the outcomes of lumbar fusion surgery in patients with PD using a large, public, national database. Methods: The Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) was used to identify elective lumbar spinal fusion patients with and without PD for the years 2000 to 2012. PD patients were matched with non-PD controls for comorbidity and age using propensity score matching. Univariable and multivariable logistic regression were used to determine the relationship between PD and surgical outcomes in the matched cohort. Results: A total of 231 351 elective lumbar fusion patients were examined, of which 1332 had PD. Before matching, elective lumbar fusion patients with PD were significantly older ( P < .001) and more likely male ( P < .001) compared with non-PD patients. In the matched cohort, PD was associated with increased length of stay (6.91 vs 5.78 days) ( P < .001) and total hospital charges ($129 212.40 vs $110 324.40) ( P < .001). There was no significant difference in overall in-hospital complication rate between PD patients and matched non-PD patients (22.3% vs 21.4%) ( P = .524). Conclusions: Analysis demonstrated significant increases in length and cost of hospitalization for elective lumbar spinal fusion in patients with PD. However, inpatient complication rates in PD patients were not significantly increased. As a growing number of PD patients undergo elective spine surgery, further studies are needed to optimize operative planning. Further study is needed to assess the long-term outcomes of lumbar spinal fusion in PD.
Classification of the minerals of the graftonite group
Authors: Hawthorne Frank C. , Pieczka Adam 
Published: May 2018

ABSTRACTA classification and nomenclature scheme has been approved by the International Mineralogical Association Commission on New Minerals, Nomenclature and Classification for the minerals of the graftonite group. The crystal structures of these minerals have three distinct sites that are occupied by Fe2+, Mn2+and Ca2+. These sites have coordination numbers [8], [5] and [6], and these differences lead to very strong order of Fe2+, Mn2+and Ca2+over these sites. As a result of this strong order, the following compositions have been identified as distinct species: graftonite: FeFe2(PO4)2; graftonite-(Ca): CaFe2(PO4)2; graftonite-(Mn): MnFe2(PO4)2; beusite: MnMn2(PO4)2; and beusite-(Ca): CaMn2(PO4)2.

Key Points
Blood and its components activated the iRhom2/ADAM17-dependent release of the proinflammatory cytokine TNF-α from macrophages. The iRhom2/ADAM17/TNF-α pathway emerged as a potential new target to prevent bone resorption following a joint bleed in mice.
Inhibition of TBC1D5 activates Rab7a and can enhance the function of the retromer cargo-selective complex
Authors: Seaman Matthew N. J. , Mukadam Aamir S. , Breusegem Sophia Y. 
Published: May 2018

ABSTRACT
The retromer complex is a vital component of the endosomal protein sorting machinery necessary for sorting into both the endosome-to-Golgi retrieval pathway and also the endosome-to-cell-surface recycling pathway. Retromer mediates cargo selection through a trimeric complex comprising VPS35, VPS29 and VPS26, which is recruited to endosomes by binding to Rab7a and Snx3. Retromer function is linked to two distinct neurodegenerative diseases, Parkinson's disease and Alzheimer's disease and modulating retromer function has been proposed as an avenue to explore for a putative therapy in these conditions. We hypothesised that activating Rab7a to promote the recruitment of retromer to endosomes could positively modulate its activity. Here, we show that inhibition of the GTPase activating protein TBC1D5 can enhance Rab7a activation and lead to a gain of function for retromer.

Published: May 2018

Abstract
The main goal of the study was to develop a model of the degree of surface porosity of a biomaterial intended for implants. The model was implemented using MATLAB. A computer simulation was carried out based on the developed model, which resulted in a two-dimensional image of the modelled surface. Then, an algorithm for computerised image analysis of the surface of the actual oxide bioceramic layer was developed, which enabled determining its degree of porosity. In order to obtain the confocal micrographs of a few areas of the biomaterial, measurements were performed using the LEXT OLS4000 confocal laser microscope. The image analysis was carried out using MountainsMap Premium and SPIP. The obtained results allowed determining the input parameters of the program, on the basis of which porous biomaterial surface images were generated. The last part of the study involved verification of the developed model. The modelling method was tested by comparing the obtained results with the experimental data obtained from the analysis of surface images of the test material.
Benenti Tensors: A useful tool in Projective Differential Geometry
Authors: Manno Gianni , Vollmer Andreas 
Published: May 2018

Abstract
Two metrics are said to be projectively equivalent if they share the same geodesics (viewed as unparametrized curves). The degree of mobility of a metric g is the dimension of the space of the metrics projectively equivalent to g. For any pair of metrics (g, ḡ) on the same manifold one can construct a (1, 1)- tensor L(g, ḡ) called the Benenti tensor. In this paper we discuss some geometrical properties of Benenti tensors when (g, ḡ) are projectively equivalent, particularly in the case of degree of mobility equal to 2.
The Strategies of Ultranationalist Discourse: This Is England and Brexit
Authors: Valdés-Miyares J. Rubén 
Published: May 2018

Abstract
A speech given by the skinhead Combo in the film This is England (2006) provides the ground for an analysis of far-right nationalism. This article uses Critical Discourse Analysis and the idea of the nation as a discursive construct to explain Combo’s strategies to gain dominance over his gang by means of rhetoric, body language, building up an ethos based on Christian and epic mythologies with ethnic connotations, drawing boundaries, and discrediting and excluding his opponents. These strategies are then compared to those of the UKIP leader Nigel Farage in his “Brexit victory” speech delivered in June 2016, which was based on a mystification of territorial boundaries, symbolic allusions to a defensive war, and a verbal construction of an ideally independent nation and a promising future. Thus, the article argues that analysis of a scene from the film set in the Thatcherite Britain of 1983 can still illuminate the articulation of later nationalist discourses.
Deindustrialization and Unsustainable Debt in Middle-Income Countries: The Case of Puerto Rico
Authors: Caraballo-Cueto Jose , Lara Juan 
Published: May 2018

AbstractPuerto Rico recently became the largest bankruptcy case in the history of the U.S. municipal bond market. This debt crisis has not been the subject of significant scrutiny in the economic literature, though many researchers focus on case studies, such as Greece and Argentina, to analyze a country’s indebtedness. The underlying economic factors that influence unsustainable debt in upper middle-income countries are generally understudied. We attempted to contribute to filling these gaps in the related literature. Using econometric analysis, we found that Puerto Rico’s government indebtedness is, to a large extent, connected to a sharp decrease in manufacturing employment (i.e. deindustrialization) suffered by this economy, and weak evidence that it was caused by an excessive government payroll or overgenerous federal programs. In light of our empirical results, we discussed how the consequences of deindustrialization ultimately led to increase government borrowing.

Published: May 2018

Abstract
Co-crystals of L-phenylalanine hydrochloride (LPAHCl) were grown by slow evaporation technique in the presence of manganese sulphate and cadmium chloride. Crystallinity of the grown crystals was confirmed by single crystal X-ray diffraction. Optical transmission spectra showed very high transmittance in the entire visible region. The cut-off wavelength was observed at 250 nm for both the crystals. The optical band gap energy was found to be 4.37 eV and 4.31 eV for the grown co-crystals of LPAHCl with MnSO4 and CdCl2, respectively. The second harmonic generation of the grown crystals was confirmed by Kurtz and Perry powder SHG method and compared with KDP. The frequency dependent dielectric properties of the co-crystals were studied at different temperatures.

Published: May 2018

Abstract

Background and aims
Research investigating differences in pain location and distribution across conditions is lacking. Mapping a patient’s pain may be a useful way of understanding differences in presentations, however the use of pain mapping during a pain provocation task has not been investigated. The aim of this study was to assess the reliability of patient and clinician rated pain maps during a pain provocation task for the anterior knee.

Methods
Participants were recruited from a larger study of professional Australian rules football players (n=17). Players were invited to participate if they reported a current or past history of patellar tendon pain. No clinical diagnosis was performed for this reliability study. Participants were asked to point on their own knee where they usually experienced pain, which was recorded by a clinician on a piloted photograph of the knee using an iPad. Participants then completed a single leg decline squat (SLDS), after which participants indicated where they experienced pain during the task with their finger, which was recorded by a clinician. Participants then recorded their own self-rated pain map. This process was repeated 10 min later. Pain maps were subjectively classified into categories of pain location and spread by two raters. Pain area was quantified by the number of pixels shaded. Intra- and inter-rater reliability (between participants and clinicians) were analysed for pain area, similarity of location as well as subjective classification.

Results
Test-retest reliability was good for participants (intraclass correlation coefficients [ICC]=0.81) but only fair for clinicians (ICC=0.47) for pain area. There was poor agreement between participants and clinicians for pain area (ICC=0.16) and similarity of location (Jaccard index=0.19). Clinicians had good inter- and intra-rater reliability of classification of pain spread (k=0.75 and 0.67).

Conclusions
Participant completed pain maps were more reliable than clinician pain maps. Clinicians were reliable at classifying pain based on location and type of spread.

Implications
Clinicians should ask patients to complete their own pain maps following a pain provocation test, to elicit the most reliable and consistent understanding of their pain perception.
The Effect of Accelerated Aging on the Properties of Nitrile Butadiene Rubber (NBR) O-Rings
Authors: Zhang Weifang , Lou Weitao , Liu Xuerong , Xu Dan , Zhang Jingyu 
Published: May 2018

Abstract
The degradation behaviors and mechanisms of nitrile butadiene rubber O-rings aged in air are investigated by accelerated aging tests at different temperatures. The compressive stress changes of nitrile butadiene rubber O-rings are monitored by using a self-designed test device during the degradation process. The aging samples under different conditions are evaluated by measuring attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy, crosslinking density, compressive stress relaxation, weight loss, mechanical properties, and fracture morphology. The results demonstrate that the compressive stress declines with aging time, and the higher the temperature is, the faster the stress decreases. The ATR-FTIR results indicate that amide groups and hydroxyl groups are formed during the degradation process. The elevated temperature plays a significant role in the surface chemical changes. The changes in the crosslinking density of the samples could be attributed to the competition between crosslinking and chain scission, and the crosslinking mainly predominates in the aging process. The results of mechanical properties show that the tensile strength, elongation at break, and hardness of samples changes significantly with aging time and temperature. In addition, the fracture morphology observation reveals that the formation of a hardened brittle outer layer, voids, and agglomerates lead to a further decrease in mechanical properties. These results are very important for evaluating the lifetime of rubber O-rings and can be utilized to improve the stability and durability of sealing systems.
Szinuszhullámú és amplitúdómodulált beszéd észlelésének vizsgálata Magyar mondatok segítségével
Authors: Jakab Zoltán , Nagyné Ringer Gabriella , Víg Julianna , Szabó Pál Tamás 
Published: May 2018

Háttér és célok: Kutatásunkban elszegényített beszédingerek két típusát használtuk gyerekek és felnőttek beszédészlelési képességének vizsgálatára.Módszer: Vizsgálatunkat 5-6 éves gyermek és felnőtt mintán végeztük, szinuszhullámú és amplitúdómodulált beszédingerek – magyar nyelvű mondatok – segítségével. Beszédingereinket természetes kiejtésű változatokból szintetizáltuk.Eredmények: Korábbi angol nyelvű vizsgálatok eredményeihez hasonlóan azt tapasztaltuk, hogy mindkét korcsoport igen jól érti ezeket a szintetizált beszédfajtákat, bár a felnőttek jobban teljesítenek a gyerekeknél. Ugyanakkor adataink eltérő képet mutatnak a kétféle szintézistípus viszonyáról az angol nyelvű vizsgálatokhoz képest. Míg angol anyanyelvű mintáknál a gyerekek a szinuszhullámú beszédet relatíve jobban értették, mint az amplitúdómoduláltat, felnőtteknél pedig ez a viszony megfordult, a magyar nyelvű vizsgálatok esetén gyerekeknél egyforma teljesítményt találtunk a kétféle ingertípusra, míg felnőtteknél az amplitúdómodulált ingerek előnyét találtuk (lehetséges ugyanakkor, hogy ez csak az ingernehézségi paraméterek eltérő beállításának következménye). A lexikai restaurációs hatásokat jelezte, hogy a mondatok első főnévi csoportjának felismerése igen erősen korrelált a mondatok további részének felismerésével.Konklúzió: Adataink részben reprodukálják az angol nyelven végzett vizsgálatok eredményeit. Új eredményként kétféle perceptuális tanulási hatást sikerült elkülönítenünk: az azonnali perceptuális tanulás gyerekeknél és felnőtteknél is megfigyelhető, míg a próbák során jelentkező gyakorlási, tehát az egyes mondatok közötti transzferhatás csak felnőtteknél.

That in general in Fiqh al-Nisa ', women positioned as second actors or objects is due to several factors. First, some verses of the Qur'an and the Prophet's hadith present a patriarchal nuance, a view which places men as superior and inferior women. Secondly, the fiqh historic setting is generally a very patriarchal middle east region and the third, the fiqh writer is a man who is surely better presenting the superiority of men. Basically fiqh is the result of ijtihad miijtahid which is very good, relevant, dynamic in its era. The rigid is the thought of using the old work for the present religious rule.
