AbstractWe carried out this study to determine for how long small ruminant lentivirus (SRLV)‐specific antibodies can be detected by three commercialELISAkits in goat kids after suckling infected does in field conditions. Forty‐one kids born toSRLV‐seropositive asymptomatic does were blood sampled prior to colostrum consumption, and then weekly for 6 months in total. The sera were screened with three commercialELISA kits: whole‐virusELISA(wELISA), recombinant transmembrane and capsid antigenELISA(TM/CA‐ELISA), and surface antigenELISA(SU‐ELISA). All but one kid were seronegative in all threeELISAsright after birth. At the age of 1 week all kids turned seropositive inwELISA, 39 kids (95%) inTM/CA‐ELISA, and 35 kids (85%) inSU‐ELISA. All seropositive kids turned seronegative inwELISAby the 15th week, and inSU‐ELISAby the 19th week (median of 8 weeks in bothELISA), whereas inTM/CA‐ELISAfive kids (13% of 39 initially seropositive) were still seropositive at the age of 6 months (median of 11 weeks). Antibody levels at the age of 1 week proved significantly linked to the duration of maternal antibodies in all threeELISAsand could be employed to predict for how long maternal antibodies would remain detectable.

AbstractObjectivesTo present the clinical, radiographic, and patient‐related outcomes of patients presenting with severely resorbed ridges reconstructed with autogenous calvarial bone blocks and rehabilitated with implant‐supported prostheses.Material and methodsFrom 1998 to 2014, 72 patients presenting with severe bone defects were reconstructed with autogenous calvarial bone blocks covered with bovine bone mineral granules and collagen membranes. Four to 9 months later, 330 implants were placed and loaded 3–9 months later. The follow‐up ranged from 3 to 19 years (mean: 8.1 years). The following parameters were recorded: (a) complication rate of the reconstructive procedure; (b) bone resorption before implant placement; (c) implant survival rate and implant‐related complications; (d) peri‐implant bone resorption; and (e) patient's satisfaction inquired with a dedicated questionnaire.ResultsNo patients developed severe complications, such as complete loss or resorption of the grafts. A dehiscence occurred in six patients, which developed a mild graft resorption. The mean peri‐implant bone resorption before implant placement was 0.13 mm (SD ± 0.71). All patients received the planned number of implants. Three patients were lost during the follow‐up. The survival rate of implants at the end of the observation period was 98.5%. The mean peri‐implant bone resorption ranged from 0.00 to 4.87 mm (mean: 1.11 mm). At last, 90% of the patients were very satisfied as regards the treatment received.ConclusionsResults from this study suggested that: (a) bone volume in the areas reconstructed with calvarial grafts was stable over time; (b) survival rates of implants were consistent with those reported for implants placed in native bone; (c) patient's satisfaction was high.

AbstractObjectivesThis study aimed to analyze and compare the topographical, chemical, and osseointegration characteristics of a sandblasted acid‐etched surface (SLA group), a sandblasted thermally oxidized surface (SO group), and a surface chemically modified by hydrofluoric (HF) acid (SOF group).Materials and methodsFollowing the preparation and characterization of the relevant surfaces, 90 implants (30 for each group) were placed on the pelvic bone of six sheep. Resonance frequency analysis (RFA), insertion (ITV), removal torque value (RTV), and histomorphometric analyses (BIC%) were performed after three and 8 weeks of healing. The results were analyzed by nonparametric tests (p < 0.05).ResultsThe roughness value (Ra) in the SOF group was significantly lower than the SLA and the SO group (p = 0.136, p < 0.001, respectively). This resulted in a substantially inferior ITV 14.83 N/cm (SD: 4.04) than those achieved in the SLA and SO groups (19.50 (SD: 6.07) and 20.17 N/cm (SD: 8.95), respectively; p = 0.001). A statistically significant change in the RFA from the baseline (47.36 ISQ, SD: 6.93) to the 3rd week (62.56 ISQ, SD: 5.29) was observed in the SOF group only (p = 0.008). The highest postplacement RFA and RTV values were measured from the SLA group (61.11 ISQ, SD: 7.51 and 78.22 N/cm, SD: 28.73). The early‐term (3rd week) BIC% was highest in the SO group (39.93%, SD: 16.14). After 8 weeks, the differences in BIC% values were statistically not significant.ConclusionsAdjunct HF acid application on the thermally oxidized surface did not provide an additional benefit compared to the sandblasted and acid‐etched surface (SLA group).

AbstractObjectiveTo test if repositioning the bony plate secured with a cyanoacrylate over the antrostomy in maxillary sinus augmentation was superior to covering the antrostomy with a collagen membrane in terms of the bone augmentation area and the bone density.Material and MethodsAfter the exposure of the nasal bone in eighteen rabbits, a rectangular access window was prepared with a sonic instrument, and the bony plate was removed. A bilateral sinus mucosa elevation was performed, and the space was filled with a resorbable xenograft. On the test side, the bone plate was repositioned over the antrostomy and fixed with a cyanoacrylate. On the control side, a collagen membrane was placed over the opening. Per group, six animals were sacrificed after 2, 4, and 8 weeks of healing, respectively. Histological ground sections were prepared.ResultsThe augmented area after elevation decreased between 2 and 8 weeks from 9.4 ± 1.8 to 4.8 ± 2.8 mm2 at the test and from 9.5 ± 2.6 and 5.1 ± 1.6 mm2 at the control sites. Small amounts of new bone were seen after 2 weeks in both groups (~1.6%–2.5%) forming from the bony sinus walls. New bone density increased over time in both groups reaching ~ 10%–11% and ~ 23%–25% after 4 and 8 weeks, respectively. No statistically significant differences were found. Small residual defects were present both at the test sites in the margin of the bone plate, and at the control sites in the center of the antrostomy.ConclusionsThe bone healing in the elevated sinus space was similar irrespective of the coverage of the antrostomy. After 8 weeks, the bone plate repositioned on the antrostomy was incorporated while at the control sites the healing was still incomplete. Residual defects were still present in both groups.

AbstractGrowing enthusiasm around machine perfusion (MP) in clinical liver transplantation (LT) may be the preamble for standardized practice to expand the donors’ pool. The present systematic review investigated all the liver transplantations performed using grafts treated with MP. A systematic review of 309 papers was performed. Eventually, 27 articles were enrolled for the study. A total number of 173 cases were reported. Only 12 cohort studies were identified: the remaining ones were case reports or case series. Hypothermic machine perfusion was performed in 102 (59.0%), normothermic machine perfusion in 65 (37.6%), and controlled oxygenated rewarming in the remaining 6 (3.4%) cases. Donor characteristics, evaluation of graft quality, and endpoints were not homogeneous among the studies. Overall, post‐LT results were excellent, with 1.2 and 4.0% of patients experienced primary non‐function and ischemic‐type biliary lesions, respectively.Conclusion: Until now, no study exists that addresses the role of MP in selecting liver grafts available for LT. All the published studies mainly focused on the feasibility and safety of this new technology. Further research investigating the selection process of marginal donors is required.
Circadian regulation of neutrophils: Control by a cell‐autonomous clock or systemic factors?
Authors: Ella Krisztina , Mócsai Attila , Káldi Krisztina 
Published: June 2018

AbstractBackgroundThe circadian time‐measuring system enables the organism to anticipate and effectively respond to regular daily changes in the environment and is therefore a crucial factor of adaptation. A large body of epidemiological data underlines the circadian characteristics of human immune functions. Circadian control of neutrophil responsiveness contributes to daily changes in the pathology of both acute and chronic inflammation and may therefore time‐dependently influence the outcome of therapeutic approaches.AimThis review summarizes recent data on the role of the circadian clock in the control of immune responses, particularly of those linked to neutrophil activity, and possible mechanisms of the regulation.DiscussionIn the first section of this review we present the recent model of the mammalian molecular clock by introducing the main transcription‐translation feedback loops and discussing the pace‐setting role of post‐translational modifications. The next sections summarize clinical, epidemiological and experimental data regarding the daily control of immune responses and studies analysing expression of clock components in various leukocytes and particularly, in human peripheral neutrophils. As the latter data indicate that expression of components of the cell‐autonomous clock is relatively low in neutrophils, in the last section we review recent findings suggesting a role for systemic and local factors in the regulation of rhythmic neutrophil responses.

1. Most woody plant species in tropical habitats are primarily vertebrate‐dispersed, but interactions between ants and fallen seeds and fruits are frequent. This study assesses the species‐specific services provided by ants to fallen arillate seeds of Siparuna guianensis, a primarily bird‐dispersed tree in cerrado savanna. The questions of which species interact with fallen seeds, their relative contribution (versus vertebrates) to seed removal, and the potential effects on seedling establishment are investigated.2. Seeds are removed in similar quantities in caged and control treatments, suggesting that ants are the main dispersers on the ground. Five ant species attended seeds. Pheidole megacephala (≈0.4 cm) cooperatively transported seeds, whereas the smaller Pheidole sp. removed the seed aril on spot. Large (> 1.0 cm) Odontomachus chelifer, Pachycondyla striata, and Ectatomma edentatum individually carried seeds up to 4 m. Bits of aril are fed to larvae and intact seeds are discarded near the nest entrance.3. Overall, greater numbers of seedlings were recorded near ant nests than in control plots without nests. This effect, however, was only detected near P. megacephala and P. striata nests, where soil penetrability was greater compared with controls. Soil nutrients did not differ between paired plots.4. This study confirms the prevalence of ant–seed interactions in cerrado and shows that ant‐derived benefits are species‐specific. Ant services range from seed cleaning on the spot to seed displacement promoting non‐random spatial seedling recruitment. Although seed dispersal distances by ants are likely to be shorter than those by birds, our study of S. guianensis shows that fine‐scale ant‐induced seed movements may ultimately enhance plant regeneration in cerrado.

Published: June 2018

AbstractTo extend our knowledge of population structure of Cryphonectria parasitica in the Aegean region, 264 isolates obtained from eight subpopulations in Izmir, Manisa and Denizli provinces were studied. Only three vegetative compatibility (vc) types, EU‐1, EU‐12 and EU‐2, were identified. EU‐1 (59%) was dominant and was found in all eight subpopulations. EU‐12 (32%) was detected in six subpopulations and was highly dominant (71%) in the Ödemiş subpopulation (İzmir province). EU‐2 was restricted to only one subpopulation, Tire, but, there, had the highest frequency (50%). This is the first reported occurrence of EU‐2 in western Turkey. Regarding sexual compatibility, both MAT1‐1 and MAT1‐2 were detected in all subpopulations; however, 85% of the isolates were MAT1‐1 and no perithecia were found in any of the subpopulations. Multilocus linkage disequilibrium analysis determined that all subpopulations were clonal. Indicator co‐kriging representations showed that vc types and mating types were spatially aggregated. In combination, these results indicate that the dispersal of the pathogen most likely occurs via localized short‐distance transport of rain‐splashed asexual conidia, rather than the long‐distance dispersal of wind‐borne ascospores. Because of the presence four polymorphic vegetative incompatibility (vic) loci in certain subpopulations, C. parasitica has the potential to generate new vc types in the future.
Matching consumer feeding behaviours and resource traits: a fourth‐corner problem in food‐web theory
Authors: Monteiro Angelo Barbosa , Faria Lucas Del Bianco 
Published: June 2018

AbstractFor decades, food web theory has proposed phenomenological models for the underlying structure of ecological networks. Generally, these models rely on latent niche variables that match the feeding behaviour of consumers with their resource traits. In this paper, we used a comprehensive database to evaluate different hypotheses on the best dependency structure of trait‐matching patterns between consumers and resource traits. We found that consumer feeding behaviours had complex interactions with resource traits; however, few dimensions (i.e. latent variables) could reproduce the trait‐matching patterns. We discuss our findings in the light of three food web models designed to reproduce the multidimensionality of food web data; additionally, we discuss how using species traits clarify food webs beyond species pairwise interactions and enable studies to infer ecological generality at larger scales, despite potential taxonomic differences, variations in ecological conditions and differences in species abundance between communities.
The energy‐based multistage fatigue crack growth life prediction model for DRMMCs
Authors: Tevatia A. , Srivastava S.K. 
Published: June 2018

AbstractA complex closed form expression for the multistage fatigue crack growth life has been developed to predict the fatigue life of discontinuous reinforced metal matrix composites. The multistage fatigue crack growth model includes the microstructural features of composite such as aspect ratio, volume fraction of reinforcement, constraint of fibre in the matrix, and interfacial bonding strength. It characterizes the fatigue damage evolution in various stages of crack nucleation/initiation and the growth of crack culminating in failure. A fatigue crack initiation model is presented, using energy balance equation, considering the nucleation process of phase transformation. The short crack growth life is estimated using the dependency of cyclic crack‐tip opening displacement that is directly correlated with the fatigue crack growth rate whereas the long crack growth life is evaluated using Li and Ellyin model. The sensitivity analysis of crack initiation model is performed to provide in‐depth knowledge on the mechanistic aspect. The sensitivity analysis shows that the little variation in the parameters “cyclic strain hardening exponent” (n′), “cyclic strength coefficient” (K′), and short crack length (asc) significantly affects the total fatigue crack growth life. It is observed that reinforcement increases the cyclic plastic deformation level and cyclic plastic zone size near the crack tip, under the total strain‐controlled conditions. The effect of total fatigue crack growth life is found to be significant in low cycle fatigue applications.
DAS ‘RICHTIGE LEBEN IM FALSCHEN’: AUTORITÄRE SYSTEME UND DIE EINHEIT VON WIDERSTAND UND ANPASSUNG IN GÜNTER DE BRUYNS AUTOBIOGRAPHIEN ZWISCHENBILANZ UND VIERZIG JAHRE*
Authors: Schuh Melissa 
Published: June 2018

ABSTRACTLife writing produced after the collapse of the GDR holds public interest because its writers broach issues of compromise, guilt, and responsibility. Autobiographical narratives in particular can provide unique insights into the struggles experienced by those living under an authoritarian regime. Günter de Bruyn, born in 1926, grew up at the end of the Weimar Republic, experiencing the GDR's collapse and German unification as a writer. Critics have discussed his role as ‘the figurehead’ of post‐Unification literature, with his autobiographies seen as an honest attempt to convey the reality of life in an authoritarian society. The two volumes of his autobiography, Zwischenbilanz and Vierzig Jahre, chart his development from playing the system for personal benefit, to compromise and literary success, and finally resistance to the GDR regime. This analysis demonstrates how the key questions of the truth and value of autobiography can be addressed by showing how the writer's inner turmoil is representative of life in a complex, ambiguous, and multilayered society. Inner conflict emerges as part of the ‘habitus’ of conflicting dispositions between but also within individuals and groups. De Bruyn's account is representative of many East German intellectuals, rendering the existence of conflicting beliefs within the self an integral part of living when put to the test under authoritarian regimes.

ObjectivesPetrolatum and soybean oil are common ingredients incorporated in topical skin formulations for skin protection and moisturization. However, the stratum corneum (SC) penetration kinetics of these two cosmetic ingredients has not been systematically studied. Glyceryl monooleate (GlyMOle) has been shown to enhance skin penetration of various compounds. It was hypothesized that GlyMOle could enhance skin penetration of petrolatum and soybean oil. This study aimed to examine the in vitro skin penetration of petrolatum and soybean oil in the presence or absence of GlyMOle.MethodsSkin permeation experiments were conducted using the in vitro Franz diffusion cell model with split‐thickness human skin and human epidermal membrane (HEM). The effect of permeant dose and the kinetics of permeant penetration were examined with and without GlyMOle in vitro.ResultsPetrolatum and soybean oil were found to permeate across HEM, and no effect of GlyMOle on skin permeation into the receptor chamber was observed. GlyMOle enhanced the penetration of petrolatum into the split‐thickness skin at 50 μg dose (petrolatum:GlyMOle, 49 : 1, w/w). However, no effect of GlyMOle on petrolatum penetration was observed at 200 μg dose (of the same petrolatum:GlyMOle ratio), indicating a dose‐dependent effect. GlyMOle at the level used in the study did not enhance the penetration of soybean oil with 50 and 200 μg doses at any timepoints.ConclusionGlyMOle was a skin penetration enhancer for petrolatum under the in vitro conditions identified in this study.

AbstractObjectiveTo study the effects of the very high minerality Vichy Thermal Spring Water (VTSW) on human keratinocytes grown in vitro.MethodsThe effect of VTSW was monitored by full genome transcriptomic technology and immunofluorescence microscopy.ResultsIn the presence of 50% VTSW, the expression of a number of skin homoeostasis‐related genes is increased, specifically with respect to dermal‐epidermal junction, epidermal cohesion and communication, keratinocyte proliferation–differentiation balance, antioxidant mechanisms and DNA repair.ConclusionThis work suggests that VTSW could be considered as an ingredient of potential interest to address some of the deleterious effects of skin ageing exposome.
GREAT MODERATION AND GREAT RECESSION: FROM PLAIN SAILING TO STORMY SEAS?
Authors: Gadea María Dolores , Gómez‐Loscos Ana , Pérez‐Quirós Gabriel 
Published: June 2018

AbstractMany have argued that the Great Recession of 2008 marks the end of the reduction in output volatility known as the Great Moderation. This article shows that this is not the case through an empirical analysis. Output volatility remains subdued despite the output loss of the Great Recession. This finding has important implications for policymaking because we also find that a lower volatility of output is associated with slower recoveries.

AbstractY2O3 films were synthesized on an aluminum alloy (A5052) substrate directly using a flame‐spray apparatus with a H2‐O2 flame. The Y2O3/A5052 joining was also annealed under atmospheric conditions. Although the joining was annealed close to the melting point of the A5052 substrate, the joining showed strong adhesion without delaminations. The resultant Y2O3 coating exhibits a strong adhesion with the aluminum alloy substrate. Elemental diffusion in the joining was not observed from cross‐sectional EDX analysis. Directly ceramic film deposition method by a reactive spraying process was proposed.

Published: June 2018

AbstractTin fluorophosphate (TFP) glass, which can be used to manufacture a phosphor‐in‐glass (PiG) for achieving high‐power white light‐emitting diodes (w‐LEDs), has attracted a great deal of attention because of its low‐melting point. Mn2+‐doped ultralow glass transition temperature (~122°C) Sn–F–P–O glasses were prepared to achieve broadband visible light emission from 390 to 720 nm. By controlling the concentration of MnO, the emission color of the TFP glass can be adjusted from blue/cool white to warm white/red. In particular, 0.2 mol% MnO‐doped TFP glass, which yields bright and warm white light and has ultralow glass transition temperature and thermal stability, has a promising application prospect in the field of high‐power w‐LEDs.
