Sudden manifestation of sinus arrest nine months after catheter ablation treatment for persistent atrial fibrillation
Authors: Takigawa Masateru , Kuwahara Taishi , Okubo Kenji , Takahashi Atsushi 
Published: March 2015

AbstractA 39‐year‐old man with a seemingly non‐remodeled, small heart suffered persistent atrial fibrillation (AF). Extensive isolation of the pulmonary vein, superior vena cava, and posterior left atrium, in conjunction with right atrium focal ablation, was performed to ablate multiple AF foci during two catheter ablation sessions. Sinus arrest occurred suddenly during follow‐up, despite the absence of recurrent AF, ultimately necessitating pacemaker implantation. This case underscores the necessity of careful follow‐up after catheter ablation, highlighting the risk of sudden, severe sinus node dysfunction, even in young AF patients with small hearts.

Published: March 2015

AbstractBackground: In the past two decades, there has been increasing evidence to suggest that trigeminal neuralgia (TN) may be linked to a dysfunction of the autonomic nervous system (ANS). The aim of the present study was to formally test this hypothesis by comparing the reactivity of the ANS to experimental pain in a population of TN patients and healthy controls. Methods: Twelve patients diagnosed with classical TN and 12 healthy controls participated in the study. Cardiac activity was assessed while participants were instructed to rest and again during a cold pressor test (CPT). Heart rate variability analyses were performed off-line to obtain parasympathetic (high-frequency) and sympathetic (low-frequency) indices. Results: At baseline, ANS measures did not differ between healthy controls and TN patients, and both groups showed a similar increase in heart rate during the CPT (all p values >0.05). However, TN patients showed a greater increase in cardiac sympathetic activity and a greater decrease in cardiac parasympathetic activity during CPT compared with healthy controls (all p values <0.05). Importantly, changes in sympathetic reactivity, from baseline to CPT, were negatively associated with the number of pain paroxysms experienced each day by TN patients in the preceding week (r=−.58, p<0.05). Conclusions: These results suggest that TN, like many other short-lasting, unilateral facial pain conditions, is linked to ANS alterations. Future studies are required to determine if the altered ANS response observed in TN patients is a cause or a consequence of TN pain
Stabilization of a hypersonic boundary layer using a felt-metal porous coating

Published: March 2015

An error in the complex representation of the porous-coating model used in the study by Fedorov et al. (J. Fluid Mech., vol. 479, 2003, pp. 99–124), investigating the stabilization effect of ultrasonically absorptive coatings on hypersonic boundary layers, is pointed out and corrected. This error has been acknowledged by Fedorov et al. (J. Fluid Mech., vol. 769, 2015, pp. 725–728). The corrected version of the erroneous linear stability results of the original work is presented and previously made conclusions are reassessed. The novel numerical results indicate that second-mode instabilities are shifted to lower frequencies on felt-metal porous coatings, similar to the behaviour observed on porous coatings with regular microstructure.

Twelves Voices from Greece and Romeby Christopher Pelling and Maria Wyke sounds like a title specially commissioned by this very journal, though, alas, we can claim none of the credit! The collaboration arose out of a BBC Radio 3 series on classical literature in collaboration with the Open University and should have a broad appeal. Of the twelve voices six are Greek, six Latin: for the poets, Homer, Sappho, Virgil, Horace; for the tragedians, Euripides; for the historians Herodotus, Thucydides, Caesar, Tacitus; with Cicero for the orators (and philosophers…) and Juvenal for the satirists, paired with the final ‘voice’ in the collection: Lucian (a striking sign of the growing interest and marketability of Second Sophistic and Imperial Greek authors). This is a stimulating and enjoyable read, which carries one swiftly along. It is not a didactic regurgitation of literary and cultural history (though the final section on ‘Translations and Further Reading’ gives all the references one needs for further research) but a celebration of the continuing relevance of the Classics:The texts of the ancient world can still speak, not just to us, but with us, and in a range of exhilarating and disturbing ways. They still matter, and what they talk about can still be fresh (whether empire, masculinity, nature, urbanity, madness, rationality, religious commitment and disbelief, family and friendship, desire, or death).

Larval trematode infections in Galba truncatula (Gastropoda, Lymnaeidae) from the Brenne Regional Natural Park, central France
Authors: Rondelaud D. , Vignoles P. , Dreyfuss G. 
Published: March 2015

AbstractAdult Galba truncatula ( ≥ 4 mm in shell height) were collected from 135 habitats for 3 years (2012–2014) to identify parasite species via the study of cercariae, and to determine the prevalence of each digenean infection in relation to the type of snail habitat (six types). A total of 323 infected snails and ten digenean species were noted in the bodies of 11,025 G. truncatula after their dissection. Snails with Calicophoron daubneyi and/or Fasciola hepatica were found in 20.7% and 12.5% of the habitats, respectively, and most of these infected snails were collected from rainwater-draining furrows and pools in meadows. The percentages were lower for snails with Echinostoma revolutum (9.6% of habitats) and Haplometra cylindracea (7.4%), and were less than 5% for those parasitized by any of the other five species of digenean. The highest prevalence of all digenean infections was noted in pools (9.4%), followed by furrows located in meadows (8.3%) and ponds (5.1%). The prevalence noted for each digenean infection varied with the type of habitat. In furrows located in meadows, the infection rate of C. daubneyi in snails (3.5%) was significantly higher than that of F. hepatica (2.2%). In pools, values greater than 1.5% were noted for C. daubneyi, H. cylindracea and Opistoglyphe ranae. In ponds, E. revolutum was the dominant species (prevalence, 2.5%). Parasite species richness in G. truncatula was greater in the Brenne Natural Regional Park than in the nearby region of Limousin (ten instead of eight). The distribution and prevalence of each parasite species were dependent on the type and location of each snail habitat.

Authors: Amir I , Vernham G A 
Published: March 2015

AbstractObjective:This study aimed to report our current practice of transoral laser microsurgery for early glottic cancer against the standards outlined by the ENT UK Head and Neck Group and assess the oncological outcome.Method:A retrospective review of case notes of patients diagnosed with early glottic cancer (tumour stages Tis, T1 and T2) who underwent transoral laser microsurgery as a primary curative treatment. The minimum follow-up period was two years.Results:Thirty-one patients had transoral laser microsurgery for early glottic cancer during the study period. Eighty-four per cent of cases were discussed by a multidisciplinary team prior to transoral laser microsurgery. Complete circumferential excision was achieved in 77 per cent of cases. Sixty-five per cent of specimens were subjected to histological analysis; they complied with standard pathology reporting for margins. Within 12 months of transoral laser microsurgery, there were 10 residual cases and 2 recurrences. Kaplan–Meier survival analysis gave disease-free survival rates of 96.8 per cent at 18 months and 93.5 per cent at 24 months. The laryngectomy-free survival rate was 96.8 per cent at two years.Conclusion:The findings of this audit are encouraging and have highlighted areas for further discussions, recommendations, training and education.

AbstractIn 2011 we carried out the first systematic survey to determine the density and abundance of endemic forest primates in Siberut National Park, in the Mentawai Islands of West Sumatra, Indonesia. Distance sampling was employed to survey 18 transects located systematically throughout the Park, yielding a total survey effort of 192 km and 285 observations of primates for data analysis. From density estimates for the four resident primate species, the Siberut langurPresbytis siberu, the pig-tailed snub-nosed langurSimias concolor, Kloss's gibbonHylobates klossiiand the Siberut macaqueMacaca siberu, we extrapolated a total population of c. 51,000 primates within the Park. We conclude that Siberut National Park is of major significance for the continued survival of Siberut's endemic primates, and provide recommendations to help ensure that it will continue to function as a refuge for primates.
Molecular characterization ofTrichomonas gallinaeisolates recovered from the Canadian Maritime provinces’ wild avifauna reveals the presence of the genotype responsible for the European finch trichomonosis epidemic and additional strains

SUMMARYFinch trichomonosis, caused byTrichomonas gallinae, emerged in the Canadian Maritime provinces in 2007 and has since caused ongoing mortality in regional purple finch (Carpodacus purpureus) and American goldfinch (Carduelis tristis) populations.Trichomonas gallinaewas isolated from (1) finches and rock pigeons (Columbia livia) submitted for post-mortem or live-captured at bird feeding sites experiencing trichomonosis mortality; (2) bird seed at these same sites; and (3) rock pigeons live-captured at known roosts or humanely killed. Isolates were characterized using internal transcribed spacer (ITS) region and iron hydrogenase (Fe-hyd) gene sequences. Two distinct ITS types were found. Type A was identical to the UK finch epidemic strain and was isolated from finches and a rock pigeon with trichomonosis; apparently healthy rock pigeons and finches; and bird seed at an outbreak site. Type B was obtained from apparently healthy rock pigeons. Fe-hyd sequencing revealed six distinct subtypes. The predominant subtype in both finches and the rock pigeon with trichomonosis was identical to the UK finch epidemic strain A1. Single nucleotide polymorphisms in Fe-hyd sequences suggest there is fine-scale variation amongst isolates and that finch trichomonosis emergence in this region may not have been caused by a single spill-over event.
Euesperides: the Rescue of an Excavation
Authors: Vickers Michael , Gill David , Economou Maria 
Published: March 2015

There was a time when the Department of Antiquities at the Ashmolean Museum at Oxford was prosperous enough to support a venture which called itself the Ashmolean Expedition to Cyrenaica. The form this exercise took was the excavation over three seasons between 1952 and 1954 of parts of the site of the Greek city of Euesperides situated on the outskirts of Benghazi (Fig. 1 ).Euesperides does not figure large in history. We first hear of it in 515 in connection with the revolt of Barca from the Persians: a punitive expedition was sent by the satrap in Egypt and it marched as far west as Euesperides. Euesperides played a part in the downfall of the Battiads, the ruling house of Cyrene. Arcesilas IV tried to create a safe haven against the day when his regime might be overthrown, and in 462 in effect refounded the city with a new body of settlers attracted from all over Greece.

Recalcitrant and orthodoxSpartinaseeds or isolated embryos exhibit similar leachate patterns immediately following desiccation
Authors: Chappell James H. , Wang Yi , Cohn Marc Alan 
Published: March 2015

AbstractSolute leakage is used as an indicator of membrane damage during desiccation of recalcitrant seeds. We re-examined this phenomenon and its utility by comparing recalcitrantSpartina alternifloraand orthodoxSpartina pectinataseeds, as well as drying isolated embryos or embryos isolated after whole-seed drying. During drying, intact seed leakage (electrical conductivity and absorbance at 280 nm) was independent of seed moisture content, dormant/non-dormant state or desiccation tolerance. Embryos from bothSpartinaspecies, isolated after drying within the intact seed, exhibited increased leakage, especially below 40% (dry weight basis, DWB) seed moisture, the critical water content for viability loss inSpartina alterniflora. When isolated embryos were dried, the pattern and extent of increased solute leakage were similar in bothSpartinaspecies, even thoughS. pectinataembryos were >95% viable andS. alternifloraembryos were < 20% viable. We conclude that increased solute leakage is an artefact of embryo excision and not an accurate indicator of desiccation damage to recalcitrantSpartina alternifloraseeds.
Which functional unit to identify sustainable foods?
Authors: Masset Gabriel , Vieux Florent , Darmon Nicole 
Published: March 2015

AbstractObjectiveIn life-cycle assessment, the functional unit defines the unit for calculation of environmental indicators. The objective of the present study was to assess the influence of two functional units, 100 g and 100 kcal (420 kJ), on the associations between three dimensions for identifying sustainable foods, namely environmental impact (via greenhouse gas emissions (GHGE)), nutritional quality (using two distinct nutrient profiling systems) and price.DesignGHGE and price data were collected for individual foods, and were each expressed per 100 g and per 100 kcal. Two nutrient profiling models, SAIN,LIM and UK Ofcom, were used to assess foods’ nutritional quality. Spearman correlations were used to assess associations between variables. Sustainable foods were identified as those having more favourable values for all three dimensions.SettingThe French Individual and National Dietary Survey (INCA2), 2006–2007.SubjectsThree hundred and seventy-three foods highly consumed in INCA2, covering 65 % of total energy intake of adult participants.ResultsWhen GHGE and price were expressed per 100 g, low-GHGE foods had a lower price and higher SAIN,LIM and Ofcom scores (r=0·59, −0·34 and −0·43, respectively), suggesting a compatibility between the three dimensions; 101 and 100 sustainable foods were identified with SAIN,LIM and Ofcom, respectively. When GHGE and price were expressed per 100 kcal, low-GHGE foods had a lower price but also lower SAIN,LIM and Ofcom scores (r=0·67, 0·51 and 0·47, respectively), suggesting that more environment-friendly foods were less expensive but also less healthy; thirty-four sustainable foods were identified with both SAIN,LIM and Ofcom.ConclusionsThe choice of functional unit strongly influenced the compatibility between the sustainability dimensions and the identification of sustainable foods.
Effects of Anti-Black Political Messages on Self-Esteem
Authors: Lyle Monique L. 
Published: March 2015

AbstractThis study examines how anti-Black political rhetoric affects race-specific collective self-esteem (R-CSE) and internal political efficacy among African–Americans and Whites. Results from an experiment in which subjects received an anti-Black stereotype-accentuating message attributed to either a political figure or an “ordinary American,” or no message at all, demonstrate that the political message undermined how African–Americans regard their own racial group, activated beliefs about how others regard African–Americans as a predictor of how African–Americans regard their own racial group, and undermined internal political efficacy. For Whites, the results demonstrate that the political message moderated the relationship between how they regard their own racial group and beliefs about how others regard their racial group, though the political message did not significantly increase or decrease racial group-regard or political efficacy overall. These results provide empirical confirmation of the role that government and politics can play in self-esteem.

AbstractSeasonal influenza A viruses cause annual epidemics of respiratory disease; highly pathogenic avian H5N1 and the recently emerged H7N9 viruses cause severe infections in humans, often with fatal outcomes. Although numerous studies have addressed the pathogenicity of influenza viruses, influenza pathogenesis remains incompletely understood. Here we generate influenza viruses expressing fluorescent proteins of different colours (‘Color-flu’ viruses) to facilitate the study of viral infection in in vivo models. On adaptation to mice, stable expression of the fluorescent proteins in infected animals allows their detection by different types of microscopy and by flow cytometry. We use this system to analyse the progression of viral spread in mouse lungs, for live imaging of virus-infected cells, and for differential gene expression studies in virus antigen-positive and virus antigen-negative live cells in the lungs of Color-flu-infected mice. Collectively, Color-flu viruses are powerful tools to analyse virus infections at the cellular level in vivo to better understand influenza pathogenesis.
Ferromagnetism induced by entangled charge and orbital orderings in ferroelectric titanate perovskites

Published: March 2015

AbstractIn magnetic materials, the Pauli exclusion principle typically drives anti-alignment between electron spins on neighbouring species resulting in antiferromagnetic behaviour. Ferromagnetism exhibiting spontaneous spin alignment is a fairly rare behaviour, but once materialized is often associated with itinerant electrons in metals. Here we predict and rationalize robust ferromagnetism in an insulating oxide perovskite structure based on the popular titanate series. In half-doped layered titanates, the combination of Jahn–Teller and oxygen breathing motions opens a band gap and creates an unusual charge and orbital ordering of the Tidelectrons. It is argued that this intriguingly intricate electronic network favours the elusive inter-site ferromagnetic (FM) ordering, on the basis of intra-site Hund's rules. Finally, we find that the layered oxides are also ferroelectric with a spontaneous polarization approaching that of BaTiO3. The concepts are general and design principles of the technologically desirable FM ferroelectric multiferroics are presented.
Risk factors associated with Rift Valley fever epidemics in South Africa in 2008–11

Published: March 2015

AbstractRift Valley fever (RVF) is a zoonotic and vector-borne disease, mainly present in Africa, which represents a threat to human health, animal health and production. South Africa has experienced three major RVF epidemics (1950–51, 1973–75 and 2008–11). Due to data scarcity, no previous study has quantified risk factors associated with RVF epidemics in animals in South Africa. Using the 2008–11 epidemic datasets, a retrospective longitudinal study was conducted to identify and quantify spatial and temporal environmental factors associated with RVF incidence. Cox regressions with a Besag model to account for the spatial effects were fitted to the data. Coefficients were estimated by Bayesian inference using integrated nested Laplace approximation. An increase in vegetation density was the most important risk factor until 2010. In 2010, increased temperature was the major risk factor. In 2011, after the large 2010 epidemic wave, these associations were reversed, potentially confounded by immunity in animals, probably resulting from earlier infection and vaccination. Both vegetation density and temperature should be considered together in the development of risk management strategies. However, the crucial need for improved access to data on population at risk, animal movements and vaccine use is highlighted to improve model predictions.
