Effect of Anxiety and Depression on the Recurrence of Paroxysmal Atrial Fibrillation. Introduction: Whether circumferential pulmonary vein ablation (CPVA) can alleviate anxiety and depression symptoms is unknown and the effect of anxiety and depression on the recurrence of atrial fibrillation (AF) after CPVA is not clear.
Methods:
Two hundred and ten patients with a diagnosis of paroxysmal AF were admitted in the study. Ninety‐eight patients (CPVA group) and 102 patients (medicine group) were treated with CPVA and antiarrhythmic drugs, respectively. All patients were followed up for 1 year. Zung Self‐Rating Anxiety Scale (SAS), Zung Self‐Rating Depression Scale (SDS), and Short‐Form life survey‐36 items (SF‐36) were assessed before and after follow‐up.
Results:
In CPVA group, the scores of SAS and SDS decreased (41.69 ± 8.32 vs 37.66 ± 4.82, P < 0.001 and 45.01 ± 9.71 vs 40.05 ± 8.56, P < 0.001, respectively) and SF‐36 score improved (565.29 ± 143.37 vs 606.84 ± 102.84, P = 0.021) after follow‐up. Compared with the data in recurrent patients, the SAS and SDS scores were significantly lower in nonrecurrent patients at baseline (44.68 ± 8.40 vs 38.10 ± 7.55, P < 0.001 and 51.75 ± 9.41 vs 43.96 ± 8.95, P < 0.001, respectively). The results of multivariate logistic regression analysis showed normalized scores of SAS (OR = 3.20, 95% CI [3.05, 3.48], P = 0.023) and SDS (OR = 3.26, 95% CI [3.12, 3.49], P = 0.023) were the independent risk factor of AF recurrence after CPVA.
Conclusions:
CPVA can ameliorate anxiety and depression, which may contribute to improvement of quality of life in patients with paroxysmal AF. Anxiety and depression increase the recurrence risk of AF after CPVA. (J Cardiovasc Electrophysiol, Vol. 23, pp. S17‐S23, November 2012)

Published: August 2012

AbstractVarious 9‐mm ammunitions (A1, A4, A5, ST, GS, GSb, P.E.P., SeCa, HP, PTP/s, VM, McVG, DM41, PTP, SX2, PT, and MEN frangible) were tested regarding their velocity, energy, angle of impact, and potential wound channel after penetrating a car window at 30° and 90°. Test materials were gelatine, soap, and pig cadavers. The velocities of the projectiles were between c. 288 and 430 m/ses, the energy spread between 394 and 564 J. Handgun bullets fired through vehicular side window glass lose substantial energy reducing the effectiveness of the ammunition. This effect is greater when fired at an angle of 30° compared to 90°. At a shooting angle of 90°, none of the different projectiles showed remarkable differences considering its wound ballistic features. Accuracy is maintained at a 90° angle but seriously impaired at 30°. None of the examined ammunition complied with the demanded wound channel effectiveness of 30–60 J/cm.

AbstractThe mating performance of Glossina palpalis gambiensis Vanderplank (Diptera: Glossinidae) mass‐reared in Burkina Faso (BKF strain) was compared with that of target populations originating from the Bamako peri‐urban area of the Niger River Basin, Mali (MLI strain) and the Niayes area, Senegal (SEN strain). The tests were carried out using a field cage either set up outdoors in Burkina Faso or inside the laboratory in Austria. The target population strains (MLI and SEN) were a few generations from the wild whereas the laboratory‐reared flies (BKF) were adapted to laboratory rearing over many generations. The laboratory‐reared BKF strain significantly out‐competed the MLI strain in the mating tests, but showed close to equal competitiveness with the SEN strain. At least one‐third of possible matings occurred during each observation period. The females from the two target populations readily mated with males from the BKF strain. The selected mating parameters and behaviour in the cage showed that there was mating compatibility between the strains and this absence of obvious mating barriers indicates the potential of using BKF strain males in programmes that have a sterile insect technique (SIT) component targeting the two G. p. gambiensis populations of Mali and Senegal.
When mating disruption does not disrupt mating: fitness consequences of delayed mating in moths
Authors: Mori Boyd A. , Evenden Maya L. 
Published: August 2012

AbstractThe goals of pheromone‐mediated mating disruption are to interfere with mate finding, suppress insect population growth, and prevent crop damage. In addition to prevention of mating, pheromone treatment can also result in a delay of mating so that the fitness and subsequent population dynamics of the target insect pest are impacted. Females have a limited time to mate, mature eggs, and find suitable oviposition hosts, and a delay in mating can have large consequences on female fitness. As a result, delayed mating could be considered an indirect method by which mating disruption works to control pest populations. We perform a meta‐analysis on 24 experimental studies to assess the consequences of delayed mating on female moth fecundity, egg fertility, adult longevity, and pre‐oviposition period. Our goal is to determine whether the effect of delayed mating on female moth fitness is influenced by the following explanatory variables: moth family, voltinism, larval diet breadth, adult dispersal capacity, female mating strategy, and egg development strategy. Across species, the effect of delayed mating on female moths significantly decreases fecundity, fertility, and pre‐oviposition period and increases female longevity. The effect of delayed mating on female fitness is only marginally affected by the explanatory variables tested. We discuss the observed patterns and argue that delayed mating can be an important method by which population regulation is achieved through pheromone‐mediated mating disruption. Finally, we highlight areas where future research could add to the growing body of knowledge on mating disruption‐imposed delayed mating of female moths.

AbstractTo verify current thresholds for Bollgard II® cotton in Australia, the impact of Helicoverpa spp. (Lepidoptera: Noctuidae) larvae on yield, development, and quality under various infestation intensities and durations, and stages of growth, was tested using small plot field experiments over two seasons. Infestation with up to 80 eggs m−1 of Helicoverpa armigera (Hübner) and Helicoverpa punctigera Wallengren showed that species, infestation level, and stage of growth had no significant effect on yields of seed‐cotton or lint and on maturity and fibre quality. The duration of infestation of white flowers with H. punctigera neonates (maximum of every day for up to 4 weeks) had no impact on the yield of seed‐cotton or lint, maturity, and fibre quality, but when 100% of flowers were infested (compared with 0 or 50%), seed‐cotton and lint yields were significantly reduced and maturity was delayed. Infestation with up to 18 medium H. armigera larvae m−1 at several plant stages did not significantly affect yields of seed‐cotton and lint, maturity, and fibre quality. A heliocide spray applied on a commercial farm at the current threshold resulted in a significantly higher lint yield, compared with a farm where no spray was applied. In conclusion, Bollgard II® cotton is highly resistant to Helicoverpa spp. infestation.

AbstractPurposeThe aim of this study was to prospectively evaluate the clinical and radiographic outcomes of immediate full‐arch fixed maxillary prosthesis supported by two axial and four tilted implants after 3 years of loading.Materials and MethodsThirty‐two patients with atrophic maxilla were consecutively enrolled and treated. Each patient received a fixed full‐arch maxillary rehabilitation supported by four tilted implants that engaged the posterior and the anterior sinus walls and two axial anterior implants. A total of 192 implants (30 Brånemark System MK IV and 162 NobelSpeedy Groovy, Nobel Biocare AB, Göteborg, Sweden) were inserted and immediately loaded. The definitive restorations were placed 6 months later, and follow‐up visits were scheduled every 6 months. During follow‐ups, marginal bone loss (MBL), plaque and bleeding scores, and patient's satisfaction were recorded.ResultsAll patients reached at least 3‐year follow‐up examination (range 36–78, average 55.53 months). Two tilted implants failed before delivering the definitive restoration, resulting in a cumulative survival rate of 98.96%. All final prostheses were stable and functional, resulting in a cumulative survival and success rate of 100%. At the 3‐year follow‐up there was no significant difference in MBL between axial (1.55 ± 0.31 mm) and tilted implants (1.46 ± 0.19 mm) (p = .05). Plaque and bleeding scores decreased over time, while patient's satisfaction in both aesthetics and function increased.ConclusionsImplants placement with this configuration could be considered a predictable and cost‐ and time‐effective alternative approach for the immediate restoration of the edentulous maxilla, avoiding bone grafting procedures, even with a medium‐term follow‐up.

Published: August 2012

AbstractPurposeThe purpose of this prospective study was to investigate the clinical success of a treatment protocol for the rehabilitation of edentulous posterior maxilla consisting of the positioning of short implants in combination with transcrestal sinus lifting, with the adjunct of pure (leukocyte‐free) platelet‐rich plasma, in order to reducing the risk of membrane perforation and other surgical complications.Materials and MethodsA total of 25 patients (65 implants) were treated. Pure platelet‐rich plasma was used in the sinus membrane lifting procedure. Implants of 8.5 mm length or shorter were splinted through the prosthetic rehabilitation with one or more implants longer than 10 mm.ResultsAfter a follow‐up period ranging from 12 to 19 months (mean 14.4 months) after prosthetic loading, 23 patients (60 implants) were evaluated. Overall implant success and survival rates were 100% at 1 year follow‐up visit. All prosthetic rehabilitations were successful and in function. After 1 year of loading, peri‐implant bone loss averaged 0.34 ± 0.21 mm for 8.5 mm or shorter implants (n = 25) and 0.36 ± 0.30 mm for longer implants (n = 35) (overall mean 0.35 ± 0.25 mm) without significant difference between the two groups (p = 0.23).ConclusionsThe proposed treatment protocol is a viable option for the rehabilitation of edentulous posterior atrophic maxilla.

Abstract
We report on the serendipitous discovery of a carbon star near the centre of the low-metallicity globular cluster NGC 6426. We determined its membership and chemical properties using medium-resolution spectra. The radial velocity of −159 km s−1 makes it a member of the cluster. We used photometric data from the literature and the COMARCS stellar atmospheric models to derive its luminosity, effective temperature, surface gravity, metallicity, and approximate C, N and O abundance ratios. According to these properties, we suggest that this star is a genuine carbon-rich low-metallicity asymptotic giant branch star.
Population viability analysis: using a modeling tool to assess the viability of tapir populations in fragmented landscapes
Authors: MEDICI Emília Patrícia , DESBIEZ Arnaud Leonard Jean 
Published: August 2012

AbstractA population viability analysis (PVA) was conducted of the lowland tapir populations in the Atlantic Forest of the Pontal do Paranapanema region, Brazil, including Morro do Diabo State Park (MDSP) and surrounding forest fragments. Results from the model projected that the population of 126 tapirs in MDSP is likely to persist over the next 100 years; however, 200 tapirs would be required to maintain a viable population. Sensitivity analysis showed that sub‐adult mortality and adult mortality have the strongest influence on the dynamics of lowland tapir populations. High road‐kill has a major impact on the MDSP tapir population and can lead to population extinction. Metapopulation modeling showed that dispersal of tapirs from MDSP to the surrounding fragments can be detrimental to the overall metapopulation, as fragments act as sinks. Nevertheless, the model showed that under certain conditions the maintenance of the metapopulation dynamics might be determinant for the persistence of tapirs in the region, particularly in the smaller fragments. The establishment of corridors connecting MDSP to the forest fragments models resulted in an increase in the stochastic growth rate, making tapirs more resilient to threats and catastrophes, but only if rates of mortality were not increased when using corridors. The PVA showed that the conservation of tapirs in the Pontal region depends on: the effective protection of MDSP; maintenance and, whenever possible, enhancement of the functional connectivity of the landscape, reducing mortality during dispersal and threats in the unprotected forest fragments; and neutralization of all threats affecting tapirs in the smaller forest fragments.
The coexistence of Baird's tapir (Tapirus bairdii) and indigenous hunters in northeastern Honduras
Authors: DUNN Marc , ESTRADA Nereyda , SMITH Derek A. 
Published: August 2012

AbstractThe Baird's tapir (Tapirus bairdii) is a popular game species throughout Central America, particularly among indigenous populations, and is currently endangered. Research on Miskitu hunting was conducted over 4 months in a remote region in northeastern Honduras that overlaps with the Río Plátano Biosphere Reserve. The hunting zone was mapped together with hunters and interviews were conducted with elders and other community members about tapir hunting. Results show that tapir harvesting is targeted toward specific habitats at specific times of year. Harvest rates for one year suggest that tapir hunting in the area exceeds estimates of maximum sustainable production. Nevertheless, field surveys reveal the presence of tapir within 1 km of the community, and its harvest tends to be nearby, in both forested and agricultural landscapes, suggesting that the animal has not been depleted in the area. It appears that the existence of forest areas adjacent to the hunting zone that do not experience hunting, together with the anthropogenic habitats created through shifting cultivation, are factors that help explain the presence of tapirs in the area. The article concludes with a discussion regarding the potential positive role of indigenous hunters in tapir conservation throughout its distribution range.

AbstractBaird's tapir (Tapirus bairdii) is currently endangered throughout its neotropical range with an expected population decline >50% in the next 30 years. We present the first density estimation of Baird's tapir for the Talamanca mountains of Costa Rica, and one of the first for the country. Ten stations with paired cameras were established in Valle del Silencio within Parque Internacional La Amistad (PILA). Seventy‐seven tapir pictures of 15 individuals comprising 25 capture–recapture events were analyzed using mark‐recapture techniques. The 100% minimum convex polygon of the sampled area was 5.7 km2 and the effective sampled area using half mean maximum distances moved by tapirs was 7.16 km2. We estimated a tapir density of 2.93 individuals/km2 which represents the highest density reported for this species. Intermountain valleys can represent unique and important habitats for large mammal species. However, the extent of isolation of this population, potentially constrained by steep slopes of the cordillera, remains unknown. Further genetic and movement studies are required to understand meta‐population dynamics and connectivity between lowland and highland areas for Baird's tapir conservation in Costa Rica.

Please cite this paper as: Peci et al. (2012) Community‐acquired respiratory viruses and co‐infection among patients of Ontario Sentinel practices, April 2009 to February 2010. Influenza and Other Respiratory Viruses 7(4), 559–566.Background  Respiratory viruses are known to cocirculate but this has not been described in detail during an influenza pandemic.Objectives  To describe respiratory viruses, including co‐infection and associated attributes such as age, sex or comorbidity, in patients presenting with influenza‐like illness to a community sentinel network, during the pandemic A(H1N1)pdm09 in Ontario, Canada.Methods  Respiratory samples and epidemiologic details were collected from 1018 patients with influenza‐like illness as part of respiratory virus surveillance and a multiprovincial case–control study of influenza vaccine effectiveness.Results  At least one virus was detected in 668 (65·6%) of 1018 samples; 512 (50·3%) had single infections and 156 (15·3%) co‐infections. Of single infections, the most common viruses were influenza A in 304 (59·4%) samples of which 275 (90·5%) were influenza A(H1N1)pdm09, and enterovirus/rhinovirus in 149 (29·1%) samples. The most common co‐infections were influenza A and respiratory syncytial virus B, and influenza A and enterovirus/rhinovirus. In multinomial logistic regression analyses adjusted for age, sex, comorbidity, and timeliness of sample collection, single infection was less often detected in the elderly and co‐infection more often in patients <30 years of age. Co‐infection, but not single infection, was more likely detected in patients who had a sample collected within 2 days of symptom onset as compared to 3–7 days.Conclusions  Respiratory viral co‐infections are commonly detected when using molecular techniques. Early sample collection increases likelihood of detection of co‐infection. Further studies are needed to better understand the clinical significance of viral co‐infection.
A Spectroscopic Survey of Substituted Indoles Reveals Consequences of a Stabilized 1Lb Transition

Published: August 2012

AbstractAlthough tryptophan is a natural probe of protein structure, interpretation of its fluorescence emission spectrum is complicated by the presence of two electronic transitions, 1La and 1Lb. Theoretical calculations show that a point charge adjacent to either ring of the indole can shift the emission maximum. This study explores the effect of pyrrole and benzyl ring substitutions on the transitions' energy via absorption and fluorescence spectroscopy, and anisotropy and lifetime measurements. The survey of indole derivatives shows that methyl substitutions on the pyrrole ring effect 1La and 1Lb energies in tandem, whereas benzyl ring substitutions with electrophilic groups lift the 1La/1Lb degeneracy. For 5‐ and 6‐hydroxyindole in cyclohexane, 1La and 1Lb transitions are resolved. This finding provides for 1La origin assignment in the absorption and excitation spectra for indole vapor. The 5‐ and 6‐hydroxyindole excitation spectra show that despite a blue‐shifted emission spectrum, both the 1La and 1Lb transitions contribute to emission. Fluorescence lifetimes of 10 ns for 5‐hydroxyindole are consistent with a charge acceptor‐induced increase in the nonradiative rate (1).

ObjectiveTo compare the proliferative activity in ameloblastoma and malignant odontogenic tumors, as assessed by Ki‐67 immunostaining and determine whether expression of substance P (SP) and NK‐1 receptor (NK‐1R) is related to cell proliferation in these tumors.Materials and methodsImmunohistochemistry was used to evaluate protein expression in 44 benign and malignant odontogenic tumors from 39 patients. Immunohistochemistry was performed with anti‐SP, anti‐NK‐1R, and anti‐Ki‐67 monoclonal antibodies, and the clinical and pathological data of the patients with odontogenic tumor were evaluated.ResultsExpression of Ki‐67 in malignant odontogenic tumors was significantly higher than in ameloblastomas (P < 0.001), and the expression level was associated with higher expression of NK‐1R. Among the ameloblastomas, there was significantly higher expression of Ki‐67 in peripheral ameloblastic‐like cells (3.3 ± 4.1) than in stellate reticulum‐like cells (2.6 ± 3.7) (P = 0.04). In the majority of tissue locations of the malignant tumors, expression of SP and NK‐1R was positively correlated with higher expression of Ki‐67.ConclusionThese findings show that the expression level of Ki‐67 in ameloblastomas was positively correlated with the rate of growth of odontogenic tumors. Overexpression of NK‐1R complex in malignant odontogenic tumors could be part of the trigger stimulus that results in higher proliferative activity of the tumor.
