Isolated domains of recombinant human apo-metallothionein 1A are folded at neutral pH: a denaturant and heat-induced unfolding study using ESI-MS
Authors: Irvine Gordon W. , Korkola Natalie , Stillman Martin J.
Published: June 2018

Metallothioneins (MTs) are characterized by their high metal loading capacity, small molecular weight, and abundant cysteine residues. It has long been thought that metal-free, or apo-MT peptides were unstructured and only adopted as a distinct conformation upon forming the metal clusters, described as metal-induced folding. More recent studies have suggested that the presence of a globular, yet loosely defined structure actually exists that can be disrupted or unfolded. Residue modification and ion-mobility ESI (IM-ESI)-MS have been used to examine this unusual unfolding process. The structure of apo-MT plays a critical role as the starting point in the flexible metalation pathways that can accommodate numerous soft metals. ESI-MS measurements of the product species formed following the cysteine alkylation of the isolated domain fragments of recombinant human apo-MT 1A with n-ethylmaleimide (NEM) were used in the present study to monitor the denaturant- and heat-induced unfolding at physiological pH. The results indicate that these apo-MT fragments adopt distinct structures at neutral pH that react co-operatively with NEM when folded and non-cooperatively when heated or exposed to high concentrations of the denaturant guanidinium chloride (GdmCl). From these studies, we can conclude that at neutral pH, the domain fragments are folded into globular structures where some of the free cysteine residues are buried within the core and are stabilized by hydrogen bonds. Metalation therefore, must take place from the folded conformation.
Consistent Symbol Location Affects Motor Learning in Preschoolers Without Disabilities: Implications for Designing Augmentative and Alternative Communication Displays
Authors: Thistle Jennifer J. , Holmes Stephanie A. , Horn Madeline M. , Reum Alyson M.
Published: June 2018

Purpose

Designing augmentative and alternative communication (AAC) displays that minimize operational demands is an important aspect of AAC intervention. The current study compared the effect of 2 display designs on the speed of locating target words by preschoolers without disabilities.

Method

Across 5 sessions, participants in the consistent condition (
n
= 12) were asked to locate symbols on arrays that did not change, whereas participants in the variable condition (
n
= 12) utilized arrays where the symbols changed locations each session.

Results

No difference in response time across conditions was noted during the 1st session; however, by the 5th session, participants in the consistent condition demonstrated significantly faster response times than participants in the variable condition.

Conclusions

The current study illustrated an advantage of consistent symbol location for preschoolers without disabilities. Clinical applications for incorporating consistent symbol location into AAC display design are discussed; however, replication with children who use AAC is critical.

Authors: Cui Xuewu , Yang Feng , Gao Min
Published: June 2018

A novel wideband circularly polarised (CP) magnetoelectric dipole antenna, which is excited by microstrip line aperture‐coupled feeding structure, is proposed and investigated. The wide impedance bandwidth and broadband CP characteristic are achieved based on the simple feeding structure. An antenna prototype is fabricated and exemplified to validate the proposed concept. Measured results show that the proposed antenna achieves an impedance bandwidth of 65% for voltage standing wave ratio <2 from 2.97 to 5.85 GHz, the broadside maximum gain is up to 10.2 dBi. Moreover, the 3 dB axial ratio bandwidth is about 75%, ranging from 2.7 to 5.8 GHz. Stable and symmetric unidirectional radiation patterns with low backward radiations are obtained over the operating band.
High step‐up DC–DC converter with low power device voltage stress for a distributed generation system
Authors: Ai Jian , Lin Mingyao
Published: June 2018

This study presents a novel step‐up DC–DC converter with the coupled inductor and low switch voltage stress, which reduce diode voltage stress. The presented converter contains single switch, four diodes, four capacitors and one coupled inductor. When switch is turned ON, the primary side of coupled inductor is charged by the input source. Besides, the primary and secondary side of the coupled inductor is discharged in series with the input source and two capacitors to realise the high step‐up voltage gain when the switch is turned OFF. Furthermore, the clamped circuit which adopts two capacitors negative pole connection not only recycles leakage energy and obtains the high voltage conversion gain, but also is realised to reduce the voltage stress of the diode, which can be use low‐voltage rated devices with low on‐resistance. In addition, the three diodes are working on the zero‐current‐switching turn‐off, therefore, the loss is reduced and the reverse‐recovery problem is avoided. The current falling rate of the output diode is effectively restricted for the leakage inductor, therefore, its reverse‐recovery problem is effectively alleviated. Finally, a 40 V input voltage, 380 V output voltage and 400 W output power prototype circuit is established in the laboratory to verify the performance.

Published: June 2018

This study aims to evaluate the postures of workers during the activities of milking and handling dairy cattle in the Community of Campo Mourão Municipalities, in Brazil. To identify the presence of musculoskeletal symptoms, the study was divided into two stages: first, we identified the demographic profile of the sample through a questionnaire and then obtained information about problems with pain and discomfort by applying theStandardised Nordic Questionnaire. The second stage consisted of an analysis of the activity of six farms to identify the natural ergonomic risk factors. To evaluate and record the postures, we used the REBA method (Rapid Entire Body Assessment) to correlate the prevalence of pain/discomfort with the positions adopted by workers in a production system. The study demonstrated that 87% of workers had pains and showed that the main postures throughout the workday are trunk tilting and bending, characterizing a job that requires awkward postures, with a high level of effort, in most activities, which may contribute to the development of musculoskeletal injuries for these workers. The REBA method also pointed out a high level of risk. During their routine, dairy farm workers adopt harmful positions that cause a high prevalence of pain/discomfort. Ergonomic recommendations are thus proposed to reduce these awkward postures of workers and consequently improve their quality of life at work.
Green chemistry solutions for sol–gel micro-encapsulation of phase change materials for high-temperature thermal energy storage
Authors: Romero-Sanchez Maria Dolores , Piticescu Radu-Robert , Motoc Adrian Mihail , Aran-Ais Francisca , Tudor Albert Ioan
Published: June 2018

NaNO3 has been selected as phase change material (PCM) due to its convenient melting and crystallization temperatures for thermal energy storage (TES) in solar plants or recovering of waste heat in industrial processes. However, incorporation of PCMs and NaNO3 in particular requires its protection (i.e. encapsulation) into containers or support materials to avoid incompatibility or chemical reaction with the media where incorporated (i.e. corrosion in metal storage tanks). As a novelty, in this study, microencapsulation of an inorganic salt has been carried out also using an inorganic compound (SiO2) instead of the conventional polymeric shells used for organic microencapsulations and not suitable for high temperature applications (i.e. 300–500 °C). Thus, NaNO3 has been microencapsulated by sol–gel technology using SiO2 as shell material. Feasibility of the microparticles synthetized has been demonstrated by different experimental techniques in terms of TES capacity and thermal stability as well as durability through thermal cycles. The effectiveness of microencapsulated NaNO3 as TES material depends on the core:shell ratio used for the synthesis and on the maximum temperature supported by NaNO3 during use.
Nanofinishing of freeform/sculptured surfaces: state-of-the-art
Authors: Nagdeve Leeladhar , Jain V.K. , Ramkumar J.
Published: June 2018

Freeform surfaces are being used in a multiplicity of applications in different kinds of industries related to Bio-medical (Bio-implants), micro channels in micro fluidics, automotives, turbine blades, impellers of artificial heart pumps, automobiles etc. Different parts in these industries need nano-level surface finish as their functional inevitability. It is very difficult and challenging to achieve high level of surface finish, especially on the components having freeform (or sculptured) surfaces, complex shapes, and 3-D features. Surface finish is a significant factor, which affects life and functionality of a product. Many traditional and advanced finishing processes have been developed for finishing of freeform/sculptured surfaces but still it has not been possible to achieve uniform nano level surface finish specially in case of freeform surfaces. To overcome the limitations of the existing nanofinishing processes, researchers are developing new processes for uniform nanofinishing of freeform surfaces. In this article, an attempt has been made to review different nanofinishing processes employed for freeform surfaces useful in different types of applications. In addition, experimental work, theoretical analysis and existing challenges of the finishing processes have been identified to fill the research gap.
Experimental studies on preparation of the porous and small-diameter poly(ε-caprolactone) external vascular scaffold and its degradability and biocompatibility
Authors: Chen Qingyun , Jiang Xia , Feng Li
Published: June 2018

Aim: This study was aim to prepare a porous poly(ε-caprolactone) (PCL) biodegradable external vascular scaffold by dipping and leaching method, and to assess its mechanical property, degradability and biocompatibility.Methods: We used the PCL-1, PCL-2 as the raw materials and NaCl particles as the pore-forming agents to construct a porous PCL external vascular scaffold. We tested the mechanical property of the porous PCL external vascular scaffold. The degradability of the scaffold was studied in the presence of thermomyces lanuginosus lipase (TL lipase). After 1, 3, and 5, 7 days, the samples were taken out, and the pH of the media was measured. The form-stability of the scaffold was investigated by macroscopic observation and the microstructure of it was observed by SEM. The cytotoxicity of the scaffold was evaluated by CCK-8 assay.Results: PCL-1 could make a white integrated external vascular scaffold with uniform texture. When the concentration of NaCl was less than or equal to 50%, the tensile strength of the porous PCL-1 external vascular scaffolds were higher than 4.2 Mpa, which meet the demand of clinical vascular transplantation. With the degradation of the scaffold in the lipase media, the form-stability of the scaffold was seriously destroyed, the surface of the scaffold began to degrade with some honeycomb holes, and the pH of the media values were lower than the initial reading of 7.4. Rat adipose-derived stem cells (rADSCs) cultured in the extractions of the porous PCL external vascular scaffold had good proliferation and cell morphology compared to the control group.Conclusion: The porous PCL-1-50 external vascular scaffold, with the 50% concentration of NaCl, had the maximum porosity on the basis of enough mechanical strength which meets the demand of clinical vascular transplantation. Moreover, it had good biocompatibility with rADSCs and the degradation mechanism of the scaffold was surface degradation.
Dorsal Failures: From Saddle Deformity to Pollybeak
Authors: Hamilton Grant
Published: June 2018

The nasal dorsum is an important component of a rhinoplasty and may be the primary motivation for seeking surgery. The nasal dorsum is a complex three-dimensional shape that is shrouded by local anesthetic and edema during surgery. This makes an accurate assessment of the surgical changes challenging. Complications related to dorsal modification include imbalances from over- or underresection of the structures of the nasal dorsum, inadequate or overaugmentation, an open-roof deformity, pollybeak, saddle nose, inverted-V, warped cartilage, visible grafts, contour problems, graft malposition, and extrusion. This review will discuss the common problems that can occur with dorsal modification during rhinoplasty.
Functional Compromise in the Middle Vault in the Management of Revision Rhinoplasty
Authors: Friedman Oren , Wang Leo
Published: June 2018

As rhinoplasty procedures become more common, the need for revision surgeries increases as well. Unlike primary rhinoplasties, revision rhinoplasties can be more challenging because of anatomic differences from initial surgery, a lack of available cartilage, tissue remodeling responses, and other complications. As such, surgeons should be prepared to address revision rhinoplasty patients differently from primary rhinoplasty patients. Here, the authors describe a generalizable approach to revision functional rhinoplasty patients and detail some of the surgical techniques that can be employed to achieve optimal outcomes, with particular attention paid to procedures that can be used in the middle vault.

Published: June 2018

Introduction There are more than 1,500 hospital procedures included in the Brazilian Unified Healthcare System's (SUS, in the Portuguese acronym) table, which is the reference for service payment provided by establishments serving the public health network, and they are stagnant. The underfinancing of procedures is so dramatic that in some cases the amounts paid by the SUS are even lower than the taxes generated by the costs of the same procedures in Brazilian private hospitals. This article aims to compare the evolution of the compensation of neurosurgical procedures by calculating the percentile of the lag in the values transferred to both neurosurgeons and hospitals, according to the SUS table, establishing the ideal and real values according to the current inflation, in a retrospective 9-year comparison.

Methodology This is an observational, comparative, retrospective study, based on the values of medical and hospital money transfers of 25 neurosurgical procedures in 2008, which were corrected according to the 2017 National Consumer Price Index (IPCA, in the Portuguese acronym).

Results Through this study, from 2008 to 2017, the transfers of medical fees regarding neurosurgical techniques are almost completely outdated. As examples, we can mention: the external/subgaleal ventricular shunt, with a deficit of 43.6%; the electrode implant for brain stimulation, with - 41.67%; and decompressive craniotomy, with - 32.21% in relation to the corrected value. Only 4 of the 25 neurosurgeries present a value above that predicted by the IPCA, one of them being cerebral aneurysm embolization larger than 1.5 cm with a narrow neck (+ 8.0%). Regarding the money transfers to hospitals, all procedures are 43.6% lower than expected, since there was no readjustment in the amounts paid to the institutions in the analyzed period. For example, in 2008, for the transposition of the cubital nerve, R$ 267.30 were transferred, and the same amount was maintained in 2017; and, for the surgical treatment of compressive syndrome in osteofibrous tunnel at carpal level (R$ 145.18), the amount also remained fixed throughout these 9 years.

Conclusion Because they did not follow the evolution of the economy, in 80% of the surgeries, the neurosurgeons did not have their economic demands met regarding the procedures performed through SUS. And the data became even more alarming when the money transfers to hospitals were evaluated, since there was no evolution in the money transfers for any of the neurosurgeries evaluated.
Druckschmerzhafte Körperstellen – Enthesitis?
Authors: Haibel H.
Published: June 2018

Die Enthesitis ist eine häufige Manifestation bei Spondyloarthritiden (SpA) und Psoriasis- Arthritis (PsA) und tritt bei bis zu 40 % der Patienten mit SpA auf. Wegen ihrer pathognomonischen Bedeutung ist Enthesitis in verschiedenen Klassifikationskriterien für SpA und PsA als ein Eingangs- oder Nebenkriterium aufgenommen worden. Häufigste Lokalisation ist die Ferse, aber Enthesitiden können ubiquitär an Sehnenansätzen in den Knochen auftreten. Bei der Diagnose der Enthesitis sind zahlreiche Differenzialdiagnosen zu beachten, insbesondere sollten mechanisch-degenerative Ursachen unterschieden und eine Fibromyalgie ausgeschlossen werden. Als bildgebende Verfahren sind der Power Doppler Ultraschall (PDUS) und die Magnetresonanztomografie (MRT) besonders diagnostisch hilfreich. Die therapeutischen Optionen bei Enthesitis sind begrenzt. Es werden die Gabe von nichtsteroidalen Antirheumatika und lokale Steroidinjektionen empfohlen. Während in kleineren Studien für Disease Modifying Antirheumatic Drugs keine Wirksamkeit gezeigt werden konnte, haben sich TNF-alpha-Blocker, Anti-IL-17-, Anti-IL-12/23- sowie Anti-IL-23-Antikörper in randomisierten kontrollierten Studien sowohl bei SpA als auch/oder bei PsA als effektiv erwiesen. Sie sind jedoch derzeit nicht für die Therapie einer alleinig vorliegenden Enthesitis zugelassen.

First principles study of the optical emission of cadmium yellow: Role of cadmium vacancies
Authors: Giacopetti Laura , Nevin Austin , Comelli Daniela , Valentini Gianluca , Nardelli Marco Buongiorno , Satta Alessandra
Published: June 2018

We study the role of structural defects in the CdS-based cadmium yellow paint to explain the origin of its deep trap states optical emission. To this end, we combine a first principles study of Cd- and S- vacancies in the wurtzite (101¯0) CdS surface with experimental photoluminescence spectroscopy of the commercial hexagonal CdS pigment. Computational results clearly state that the presence of cadmium vacancies in the pigment surface alters the electronic structure of cadmium sulfide by forming acceptor levels in the gap of the semiconductor. Such levels are consistent with the optical emission from trap state levels detected in the CdS pigment. This finding provides a first step towards the understanding of the photo-physical mechanisms behind the degradation of this modern pigment, widely used in impressionist and modernist paintings.

An investigation of the soil seedbank and seed germination of perennial species in Belah (Casuarina pauper) woodlands in north-west Victoria
Authors: Callister Kate E. , Florentine Singarayer K. , Westbrooke Martin E.
Published: June 2018

Semiarid and arid woodlands across much of southern Australia have been subject to prolonged high total grazing pressure leading to loss of species diversity and a lack of recruitment of long-lived perennial species. Regeneration of perennial species requires grazing pressure to be maintained at low levels, but gaps remain in our ecological understanding of regeneration potential. The present study investigated the abundance of germinable seed in the soil seedbank in high quality remnants of Casuarina pauper F.Muell. ex L.A.S.Johnson (Belah) woodlands in north-west Victoria. Seed viability and response to six seed pretreatments including dry heat, wet heat, smoky water, soaking in distilled water, cold stratification and sand scarification were also tested to determine whether seed factors may be limiting regeneration. Results suggest that seed viability was not a limiting regeneration factor for nine out of the 10 perennial species tested with the exception of Alectryon oleifolius S.T. Reynolds. Only small amounts of seed from perennial species, largely Chenopodiaceae species and C. pauper, were found in the soil seedbanks of intact sites, suggesting component perennial species do not maintain long-term soil seedbanks. Results suggest that natural recovery of perennial species diversity in depauperate sites will depend on seed dispersal.

Published: June 2018

Background Technology-facilitated sexual harassment is an emerging phenomenon. This study investigates correlates of sexual harassment among young Australians. Methods: Participants aged 15-29 were recruited for an online survey. Participants reported how often in the past year they experienced sexual harassment in person, via phone, social media and dating apps. Correlates of in-person and technology-facilitated sexual harassment were identified using logistic regression. Results: Of all participants (n = 1272, 70% female), two-thirds reported sexual harassment in person, 34% through social media and 26% via phone. Of participants who used a dating app in the past year (n = 535), 57% experienced sexual harassment. Sexual harassment in person was correlated with being female (aOR = 9.2, CI = 6.9–12.2), trans and gender diverse (aOR = 2.6, CI = 1.2–5.7) and being aged 20–24 years (aOR = 1.5, CI = 1.1–2.1). Heterosexual identity reduced the odds of sexual harassment in person (aOR = 0.7, CI = 0.5–0.9). Technology-facilitated sexual harassment was correlated with female (aOR = 3.5, CI = 2.6–4.6) and trans and gender diverse identities (aOR = 3.0, CI = 1.4–6.5). Older age [25–29 years (aOR = 0.5, CI = 0.4–0.8)] and heterosexual identity (aOR = 0.7, CI = 0.5–0.9) significantly reduced the odds of technology-facilitated sexual harassment. Conclusion: Young people identifying as female, trans and gender diverse and non-heterosexual are at risk of in-person and technology-facilitated sexual harassment. Service and technology providers, academics, and policy makers must respond with innovative strategies.
Habitat of the Eastern Barred Bandicoot, Perameles gunnii, in Tasmania: an Analysis of Road-kills
Authors: Driessen M.M , Mallick S.A , Hocking G.J
Published: June 2018

The habitat requirements of the eastern barred bandicoot, Perameles gunnii, in Tasmania were investigated
with road-kill survey data and by mapping habitat features along survey routes. Road-kills of eastern barred
bandicoots were most numerous in the South-east and North-west, less common in the North-east and
Midlands, and very uncommon on the East Coast. Logistic regression of bandicoot presencelabsence
data suggested that traffic volume is the major determinant of the road-kill distribution of eastern barred
bandicoots around Tasmania. Along with traffic volume, rainfall was found to be strongly associated with
the presence of eastern barred bandicoot road-kills for the state combined and for the South-east and Northeast,
while along the Huon Highway in the South-east, soil depth was associated with the presence of roadkills.
Favoured habitat of the eastem barred bandicoot is high-quality agricultural land with deep soils and
high rainfall. It is hypothesised that clearing for agriculture in south-eastem, north-eastem and north-westem
Tasmania has opened up previously unsuitable, heavily forested habitat for colonisation by eastern barred
bandicoots. The resulting mosaic of pasture and remnant bush appears to provide ideal habitat for the
eastern barred bandicoot. However, the majority of bandicoot habitat is found on private land, making the
species vulnerable to changes in farming practices. Possible management options are briefly discussed.

Published: June 2018

Agriculture has long become a prime sector for regional development in Buton Island, although local government emphasis on perennial crops. Food crop have been developed in very limited land areas, mainly on transmigration areas, as parts of central government programs. Today, the central government has launched a national strategic program on food self-sufficiency and has imposed the local government to optimize available land for cultivating food crop. The primary aim of study is to develop rapid assessment on a spatial basis using GIS for agricultural land suitability evaluation of agriculture commodities, i.e., rice (irrigated paddy field, rainfed rice) and corn (Zea maize L.). The study was undertaken using the following procedures: (i) conducting reconnaissance soil survey based on land units; (ii) constructing soil database in a GIS; and (iii) classifying land suitability using the FAO method. Spatial data were generated from digital topographic map, soil survey, soil characteristics, as well as climate data. Preliminary results indicate that quite large area available for food crop cultivation both in the context of land suitability (mostly in S2 and S3 classes) and land availability. All data bases were managed in GIS, then it is amenable to various operations in GIS to accommodate possible additional assessment including socio-economic and policy assessment.

Authors: Iswoyo H , Dariati T , Vale B , Bryant M
Published: June 2018

Urban ecology has become a more popular concern as the awareness for mutual sharing between humans and other ecosystem members is increasing. This study aimed at assessing the value of urban farms in the city of Makassar, a fast-developing Indonesian city which according to its city council classification covered significant area of the city. The research employed Rapid Biodiversity Assessment (RBA) to assess quality of urban farms. The method assessed two important aspects of spaces in terms of ecology i.e. vegetation structures and vascular plants. Results showed the biodiversity of urban farms in Makassar compared to other typologies was high. Urban farms in Makassar in general have potential for ecological spots because despite they are more cultural than natural, their high plant biodiversity score, dominance of trees and less built areas make them always available for improvement to become more ecological spots.

The results indicate that the land conflict happened in North Polongbangkeng Sub-District had an impact on the socio-economic and cultural life of the community. The women had to play a role and the same position as the man in productive, social and domestic matters. For 25 years, the community had to avoid and wait. Since 2007, the community had thought that the contact with PTPN XIV land had ended and the community could take over the land they owned. The strategy done by women was to join the man in their fight to get back their land. They started with confronting actions to forming an organization called Polongbangkeng Farmers Unity. In 2014 the partnership program was established as an effort to settle the land conflict, though until now this program had not answered the primary needs of the community in the region.
Optimal projection methods for model order reduction of discrete-time systems
Authors: Ibrir Salim
Published: June 2018

Numerical algorithms are developed for model order reduction of discrete-time systems using both optimal projection and $H_2$-norm minimization. The state-space matrices of the reduced-order system are obtained via the solution of a convex optimization problem. Subsequently, the results are exploited for the design of non-linear reduced-order systems verifying the input-to-state stability property. Proofs of stability and error approximation bounds are provided along with numerical simulations to highlight the strengths and the validity of the theoretical results.
Black hole spin from wobbling and rotation of the M87 jet and a sign of a magnetically arrested disc
Authors: Sob’yanin (Денис Николаевич Собьянин) Denis Nikolaevich
Published: June 2018

New long-term Very Long Baseline Array observations of the well-known jet in the M87 radio galaxy at 43 GHz show that the jet experiences a sideways shift with an approximately 8–10 yr quasi-periodicity. Such jet wobbling can be indicative of a relativistic Lense–Thirring precession resulting from a tilted accretion disc. The wobbling period together with up-to-date kinematic data on jet rotation opens up the possibility for estimating angular momentum of the central supermassive black hole. In the case of a test-particle precession, the specific angular momentum is J/Mc = (2.7 ± 1.5) × 1014 cm, implying moderate dimensionless spin parameters a = 0.5 ± 0.3 and 0.31 ± 0.17 for controversial gas-dynamic and stellar-dynamic black hole masses. However, in the case of a solid-body-like precession, the spin parameter is much smaller for both masses, 0.15 ± 0.05. Rejecting this value on the basis of other independent spin estimations requires the existence of a magnetically arrested disc in M87.

We present nebular-phase spectra of the Type Ia supernova (SN Ia) 2016brx, a member of the 1991bg-like subclass that lies at the faint end of the SN Ia luminosity function. Nebular spectra are available for only three other 1991bg-like SNe, and their Co line centres are all within ≲500 km s−1 of each other. In contrast, the nebular Co line centre of SN 2016brx is blue-shifted by >1500 km s−1 compared to them and by ≈1200 km s−1 compared to the rest frame. This is a significant shift relative to the narrow nebular line velocity dispersion of ≲2000 km s−1 of these SNe. The large range of nebular line shifts implies that the 56Ni in the ejecta of SN 1991bg-like events is off-centre by ∼1000 km s−1 rather than universally centrally confined as previously suggested. With the addition of SN 2016brx, the Co nebular line shapes of 1991bg-like objects appear to connect with the brighter SNe Ia that show double-peaked profiles, hinting at a continuous distribution of line profiles among SNe Ia. One class of models to produce both off-centre and bimodal 56Ni distributions is collisions of white dwarfs with unequal and equal masses.
Fornax A, Centaurus A, and other radio galaxies as sources of ultrahigh energy cosmic rays
Authors: Matthews J H , Bell A R , Blundell K M , Araudo A T
Published: June 2018

The origin of ultrahigh energy cosmic rays (UHECRs) is still unknown. It has recently been proposed that UHECR anisotropies can be attributed to starburst galaxies or active galactic nuclei. We suggest that the latter is more likely and that giant-lobed radio galaxies such as Centaurus A and Fornax A can explain the data.
Long-Term Reliability of Neuroendoscopic Aqueductoplasty in Idiopathic Aqueductal Stenosis-Related Hydrocephalus
Authors: Marx Sascha , Baldauf Joerg , Matthes Marc , Gaab Michael R , Schroeder Henry W S
Published: June 2018

BACKGROUND

During the 1990s, endoscopic aqueductoplasty (AP) was considered to be a valuable alternative to endoscopic third ventriculostomy (ETV) in treating hydrocephalus related to idiopathic aqueductal stenosis (iAS), with promising short-term outcomes.

OBJECTIVE

To evaluate the long-term outcome of AP in the treatment of iAS.

METHODS

Long-term follow-up clinical examinations and magnetic resonance (MR) imaging were performed for patients treated by an AP for iAS in our department.

RESULTS

Twenty patients (14 female, 6 male, mean age 41.7 yr, range 0.5-67 yr) were treated between 1996 and 2002. Two patients were lost to long-term follow-up. One patient died 6 mo after AP, but death was not related to the procedure. The mean follow-up for the remaining 17 patients was 120 mo. Clinically relevant aqueductal reclosure was observed in 11/17 patients after a mean follow-up of 53.4 mo. These 11 patients underwent ETV, which has been successful during further follow-up. Four of the six remaining patients presented with no clinical symptoms, although aqueductal restenosis was observed on MR imaging. Thus, the overall failure rate of AP was 88.2%. The failures were homogeneously distributed over the entire follow-up period.

CONCLUSION

AP has a high risk of failure during long-term follow-up and is not recommended as the first choice of treatment in hydrocephalus caused by iAS. ETV should be done instead. AP may be reserved for a limited number of patients in whom ETV is not feasible but should be combined with stenting to avoid reclosure of the aqueduct.
The political economy of homeownership: a comparative analysis of homeownership ideology through party manifestos
Authors: Kohl Sebastian
Published: June 2018

America’s ‘infatuation with homeownership’ has been identified as one cause of the latest financial crisis. Based on codings of 1809 party manifestos in 19 countries since 1945, this article addresses the question of where the political ideal to democratize homeownership came from. While conservative parties have defended homeownership across countries and time, centre-left parties have oscillated between a pro-homeownership and a pro-rental position. The former occurs in Anglo-Saxon, Northern and Southern European countries, while the latter prevails among German-speaking countries. Beyond partisan effects, once a country has a majority of homeowners and parties defending homeownership, larger parties are more likely to support it. The extent of centre-left parties’ support for homeownership is further associated with higher homeownership rates, more encouraging mortgage regimes and a bigger housing bubble burst after 2007. The ideational origins of the financialization of housing and private Keynesianism are, after all, not only conservative and market-liberal.

Published: June 2018

Acetylation of histone H3 lysine 56 (H3K56) by the fungal-specific histone acetyltransferase Rtt109 plays important roles in maintaining genome integrity and surviving DNA damage. Here, we investigated the implications of Rtt109-mediated response to DNA damage on development and pathogenesis of the rice blast fungus Magnaporthe oryzae (anamorph: Pyricularia oryzae). The ortholog of Rtt109 in M. oryzae (MoRtt109) was found via sequence homology and its functionality was confirmed by phenotypic complementation of the Saccharomyces cerevisiae Rtt109 deletion strain. Targeted deletion of MoRtt109 resulted in a significant reduction in acetylation of H3K56 and rendered the fungus defective in hyphal growth and asexual reproduction. Furthermore, the deletion mutant displayed hypersensitivity to genotoxic agents, confirming the conserved importance of Rtt109 in genome integrity maintenance and genotoxic stress tolerance. Elevated expression of DNA repair genes and the results of the comet assay were consistent with constitutive endogenous DNA damage. Although the conidia produced from the mutant were not impaired in germination and appressorium morphogenesis, the mutant was significantly less pathogenic on rice leaves. Transcriptomic analysis provided insight into the factors underlying phenotypic defects that are associated with deficiency of H3K56 acetylation. Overall, our results indicate that MoRtt109 is a conserved histone acetyltransferase that affects proliferation and asexual fecundity of M. oryzae through maintenance of genome integrity and response to DNA damage.
Predictors of Reading Skills in Children With Listening Concerns
Authors: Sharma Mridula , Cupples Linda , Purdy Suzanne C.
Published: June 2018

Objectives:

Previous research shows that children with reading disorders perform poorly on auditory processing (AP) tasks. Correlational studies have also shown significant associations between some AP tasks and word and nonword reading. There is less clear evidence for AP contributions to spelling and passage reading. The aim of this research was to extend current knowledge by investigating the association between a range of AP measures used clinically and children’s reading of words, nonwords, and passages, as well as word spelling.

Design:

Regression analyses were conducted on data from 90 children 7 to 13 years of age (58 males) with reported listening and/or reading concerns. All children had normal hearing sensitivity and were tested on AP tasks including the frequency pattern test (FPT), dichotic digits test, random gap detection test, and the masking level difference. Reading tasks included word, nonword, and passage reading. Phonologic processing, core language skills, nonverbal intelligence, memory, and attention were also measured.

Results:

All multiregression analyses were fixed order with age and gender, nonverbal intelligence, core language, phoneme manipulation, and digits backward scores included in the model before AP measures. FPT was the only AP task that accounted for significant unique variance in word/nonword reading and nonword spelling, but not passage reading.

Conclusions:

The findings from this study failed to show an association between many clinically used AP measures and children’s reading and spelling outcomes. Nevertheless, they reiterate the importance of evaluating FPT in children with word reading disorders. The findings justify further investigation into the role of this test when diagnosing children with reading or spelling disorders.
