Published: November 2015

Neural dynamics preceding seizures are of interest because they may shed light on mechanisms of seizure generation and could be predictive. In healthy animals, hippocampal network activity is shaped by behavioral brain state and, in epilepsy, seizures selectively emerge during specific brain states. To determine the degree to which changes in network dynamics before seizure are pathological or reflect ongoing fluctuations in brain state, dorsal hippocampal neurons were recorded during spontaneous seizures in a rat model of temporal lobe epilepsy. Seizures emerged from all brain states, but with a greater likelihood after REM sleep, potentially due to an observed increase in baseline excitability during periods of REM compared with other brains states also characterized by sustained theta oscillations. When comparing the firing patterns of the same neurons across brain states associated with and without seizures, activity dynamics before seizures followed patterns typical of the ongoing brain state, or brain state transitions, and did not differ until the onset of the electrographic seizure. Next, we tested whether disparate activity patterns during distinct brain states would influence the effectiveness of optogenetic curtailment of hippocampal seizures in a mouse model of temporal lobe epilepsy. Optogenetic curtailment was significantly more effective for seizures preceded by non-theta states compared with seizures that emerged from theta states. Our results indicate that consideration of behavioral brain state preceding a seizure is important for the appropriate interpretation of network dynamics leading up to a seizure and for designing effective seizure intervention.SIGNIFICANCE STATEMENTHippocampal single-unit activity is strongly shaped by behavioral brain state, yet this relationship has been largely ignored when studying activity dynamics before spontaneous seizures in medial temporal lobe epilepsy. In light of the increased attention on using single-unit activity for the prediction of seizure onset and closed-loop seizure intervention, we show a need for monitoring brain state to interpret correctly whether changes in neural activity before seizure onset is pathological or normal. Moreover, we also find that the brain state preceding a seizure determines the success of therapeutic interventions to curtail seizure duration. Together, these findings suggest that seizure prediction and intervention will be more successful if tailored for the specific brain states from which seizures emerge.

Published: November 2015

A bacia sedimentar de Resende (idade Eoceno-Oligoceno) possui uma área de aproximadamente 240 km² abrangendo os municípios de Quatis, Porto Real, Resende, Itatiaia e parte de Barra Mansa. As condições de deposição na bacia ocorreram principalmente em ambientes fluviais e de leques aluviais. A região se destaca por apresentar aspectos geológicos e geomorfológicos relevantes que podem ser utilizados para atividades científicas e educacionais. Com a intenção de preservar a geodiversidade é essencial conduzir estratégias de geoconservação, no intuito de combater as ameaças ao patrimônio geológico e manter em bom estado os geossítios da região. Para alcançar este objetivo foi feito um inventário e quantificação de cinco geossítios na bacia. Os afloramentos foram registrados, fotografados, descritos e quantificados de acordo com o seu valor intrínseco, uso potencial e necessidade de proteção. Os valores mais elevados na quantificação final foram encontrados no geossítio 2 (Q = 30) e no geossítio 1 (Q = 28). Assim, ambos podem ser considerados geossítios relevantes, tornando-se necessária a aplicação de estratégias geoconservação. O estudo contou com o apoio do CNPq, CAPES e FAPERJ.Palavras chave: Patrimônio geológico, estratégias de geoconservação, bacia sedimentar de Resende. Abstract: INVENTORY AND ASSESSMENT OF RESENDE BASIN GEOSITES, RIO DE JANEIRO STATE. The Resende sedimentary basin (Eocene-Oligocene age) has an area of approximately 240 km² covering the municipalities of Quatis, Porto Real, Resende, Itatiaia and part of Barra Mansa. The deposition conditions in the basin occurred primarily in fluvial and alluvial fans environments. The region is notable for presenting geological and geomorphological relevant aspects that can be used for scientific and educational activities. With the intention to preserve the geodiversity is essential to conduct geoconservation strategies to combat threats to the geological heritage and maintain in good condition the geosites of the region. To achieve this aim was made an inventory and quantification of the five geosites in the basin. The outcrops were registered, photographed, described and quantified according to their intrinsic value, potential use and need for protection. The highest values were found in the final quantification in geosite 2 (Q = 30) and geosite 1 (Q = 28). Thus, both may be considered relevant geosites, making it necessary to implement geoconservation strategies. The study was supported by CNPq, CAPES and FAPERJ.Keywords: Geological heritage, geoconservation strategies, Resende sedimentary basin.
Analysing Bangladeshi consumers’ e-commerce security and privacy satisfactions in small to mid-sized enterprises (SMEs)

Published: November 2015

<p>The world has entered the new millennium with great hopes. E-commerce is playing the central role in transforming the old economy into the high speed economy. E-commerce has created a vast range of business opportunities for both firms and individuals in developing countries to market their products and services abroad and earn foreign exchange for the countries. While many E-commerce systems have been implemented successfully in the special business industries, a considerable number have been unsuccessful. This study aims to block this space by developing an effective assessment of E-commerce success, termed E-commerce Security &amp; Privacy Satisfaction (ESPS). This study brings about the analysis of Security &amp; Privacy Factors (SPFs) in E-commerce implementation. An attempt has been made to focus on E-commerce implementation in Bangladesh and identify the crucial barrier–cybercrime. This study also aims to design some ideas that will allow the users in Bangladesh to deal with e-commerce with safety and without cybercrime. To provide a firm stand for the study, various theoretical studies are analysed and examined allowing for in-depth knowledge on ecommerce in Bangladesh. In order to fill the gap between theoretical information and actual practices in the context of e-commerce, and security and privacy satisfaction in Bangladesh, it is very important to collect field data. The scope of this field research covers an interview of students, Academics, Government Officials and IT Professionals. As there is at present no benchmark for measuring ESPS, this study has implemented a qualitative research method. This research is the first relative lesson into small and medium enterprises, SMEs, using secured E-commerce systems in Bangladesh.</p><p>Keywords: E-Commerce, E-Business, Security &amp; Privacy, E-commerce Satisfaction, Security &amp; Privacy Factors, Evaluation, Service Commerce, Small and Medium Enterprises, SMEs.</p>

Authors: Mastrandrea Ciro Andrés , Flores Mario , García María de los Ángeles 
Published: November 2015

<p>Inicialmente las plantaciones de eucalipto (<em>Eucalyptus grandis</em> Hill ex Maiden) de Entre Ríos eran manejadas sin un destino industrial definido. Sin embargo, la dinámica de la demanda y la necesidad de diferenciar los productos promovieron la aplicación de raleos para obtener rollos de mayor diámetro. El objetivo de este trabajo fue comparar la rentabilidad de 6 tratamientos de raleo mediante indicadores financieros (VAN y TIR). Se evaluaron los siguientes tratamientos de raleo: testigo,sin intervención (1111 plantas/ha), una sola intervencióny tres intensidades (300, 500 y 700 plantas remanentes/ha), y dos intervenciones con dos intensidades (700/300y 500/300 plantas remanentes/ha), aplicados en un rodal de <em>Eucalyptus grandis</em> en Entre Ríos (Argentina). La evaluación se basó en dos esquemas de clasificacióny comercialización de trozas: 1) diferenciación de las fracciones aserrable y pulpable, 2) según diámetros de trozas en punta fina, tomando precios diferenciales pordestino y diámetro de trozas. Los tratamientos con dosraleos alcanzaron los niveles de rentabilidad más altos, así como la venta de trozas clasificadas por diámetroen punta fina resultó la alternativa comercial más conveniente. El mejor resultado financiero se logró con la aplicación del tratamiento 700/300 plantas remanentes/ha y la venta según el esquema 2.</p>

Cedrelinga catenaeformis, comúnmente llamada“tornillo”, es una de las especies forestales de mayor importancia comercial en el mercado nacional. En el presente trabajo se presenta una metodología para el proceso de enraizamiento para la producción de plantones clonales a escala comercial de esta especie. El objetivo del estudio fue evaluar el enraizamiento de estaquillas bajo el efecto de tres dosis de ácido indol-3-butírico (2000, 3000 y 4000 ppm) y dos cantidades de foliolos (tres y cuatro foliolos), utilizando microtúneles como estructura de protección. El estudio se realizó en el vivero de la empresa Reforesta Perú S.A.C. ubicado en la Región San Martín. Se empleó un diseño completamente al azar (DCA), con un arreglo factorial de 3A x 2B, el cual constó de tres repeticiones por tratamiento y seis brotes por repetición. Al término de 15 días, los brotes de tres foliolos y con dosis de AIB de 3000 ppm mostraron enraizamientos de 94,88% teniendo a los pellets Jiffy® como sustrato. Se concluye que es posible propagar <em>C.catenaeformis</em> (94,88% de enraizamiento) si se aplica la dosis adecuada de AIB en brotes con tres foliolos.

Published: November 2015

En Costa Rica, algunas especies del género Citrusson plantadas para la producción del fruto o comoárboles de servicio en cultivos de café (Coffea spp). Sinembargo, el aprovechamiento de estas plantaciones selimita solamente al fruto, por lo que al llegar al final de suvida útil, las partes leñosas del árbol son despreciadas,a pesar de ser una fuente importante de biomasa para laproducción de energía. En el presente trabajo se estudióla anatomía del xilema secundario de seis especies delgénero Citrus: C. aurantifolia (limero), C. limettioides(limón dulce), C. reticula (mandarina), C. paradisi (toronja),C. sinensis (naranja) y una variedad, C. sinensis var.Washington (naranja injertada), mediante la descripciónanatómica (macroscópica y microscópica) de la maderade estas especies, con el objetivo de aportar informaciónpara la utilización del fuste. Para ello, muestras del fustefueron descritas utilizando las normas internacionalesde descripción de madera. Los resultados mostraronque la madera de las especies de Citrus evaluadaspresentan una densidad seca menor de 500 kg/m3, textura fina a mediana, color amarrillo a amarrillo pálido,sin veteado, sabor u olor característico. Así mismo,mostraron porosidad difusa y poros solitarios, pequeñosy de alta abundancia. Se observaron radios de tipohomocelulares, de 1 a 3 células de ancho y de 10 a 25células en altura. Para el parénquima axial, se presentóuna gran variedad de tipos, que van desde paratraquealhasta el apotraqueal, y bandas de parénquima formandoanillos falsos o bien anillos anuales. La presencia decanales traumáticos y cristales en madera tambiénestuvieron presentes en todas las especies. En general,se evidencia que la anatomía de la madera de las seisespecies estudiadas presenta poca diferencia entreellas, por lo que su posible identificación a este nivel sedificulta.

The combined use of corticotomy and clear aligners: A case report
Authors: Cassetta Michele , Altieri Federica , Barbato Ersilia 
Published: November 2015

ABSTRACT

Objective:
To describe an orthodontic treatment that combines an esthetic approach (clear aligners) with surgery (alveolar corticotomy).

Materials and Methods:
A patient with moderate dental crowding and Class I skeletal and molar relationships was selected. Orthodontic records of the patient were taken. Periodontal indexes, oral health–related quality of life (OHRQoL), and treatment time were evaluated. After we reflected a full-thickness flap beyond the teeth apices, the cortical bone was exposed on the buccal aspect and a modified corticotomy procedure was performed. Interproximal corticotomy cuts were extended through the entire thickness of the cortical layer, just barely penetrating into medullary bone. Orthodontic force was applied on the teeth immediately after surgery.

Results:
Total treatment time was 2 months. Periodontal indexes were improved after correction of crowding. A deterioration of OHRQoL was limited to 3 days following surgery.

Conclusion:
This case report may encourage the use, limited to selected cases, of corticotomy associated with clear aligners to treat moderate crowding.

Published: November 2015

SUMMARY

Purpose
To evaluate stain penetration by different beverages in artificially demineralized human teeth treated with resin infiltration.

Methods and Materials
Sixty extracted human permanent molars were demineralized, treated with resin infiltration (Icon), and immersed in four different beverages (coffee, grape juice, iced tea, and distilled water; N=15) for four weeks. After aging, teeth in the distilled water group were stained with 2% methylene blue for 24 hours. All teeth were sectioned, and stain penetration was evaluated under light microscopy. Chi-square test, independent and paired sample t-test, analysis of variance with the Fisher least significant difference post hoc test, and the Kruskal-Wallis test were used to analyze the results (p&lt;0.05).

Results
Resin infiltration–treated surfaces (Icon surfaces) had statistically significant fewer samples with presence of stain penetration compared to untreated surfaces (control surfaces) (p&lt;0.001). There was also a significant decrease in depth of stain penetration in Icon surfaces compared to the control surfaces (p&lt;0.001). Among tested beverage groups, iced tea showed significantly greater depth of stain penetration (0.134±0.029 mm), followed by grape juice (0.118±0.047 mm), methylene blue (0.022±0.019 mm), and coffee (0.008±0.017 mm; p&lt;0.001).

Conclusion
Both Icon and control surfaces exhibit stain penetration by different beverages (iced tea, grape juice, and coffee). However, resin-infiltrated enamel surfaces allow significantly less depth of stain penetration compared to untreated surfaces. The iced tea group presents greatest depth of stain penetration, followed by grape juice, methylene blue, and coffee.

Published: November 2015

SummaryObjectives: To characterize the cellular composition (platelets, erythrocytes, and leukocytes) and confirm reproducibility of platelet enrichment, as well as determine the platelet activation status in the final product of a commercial platelet-rich plasma kit using canine blood.Methods: Venous blood from 20 sedated client-owned dogs was used to prepare platelet-rich plasma (PRP) from a commercial kit. Complete blood counts were performed to determine erythrocyte, leukocyte, and platelet numbers in both whole blood (WB) and resultant PRP. The WB and PRP samples from jugular (fast collection) and cephalic (slow collection) venipuncture were also compared. P-selectin externalization was measured in WB and PRP samples from 15 of 20 dogs.Results: This commercial kit produced an average percent recovery in platelets of 64.7 ± 17.4; erythrocytes of 3.7 ± 0.8, and leukocytes of 31.6 ± 10.0. Neutrophil, monocyte, and lymphocyte percent recovery was 19.6 ± 7.2, 44.89 ± 19.8, and 57.5 ± 10.6, respectively. The recovery of platelets from jugular venipuncture (59.7 ± 13.6%) was lower than from cephalic recovery (68.8 ± 19.1%). The mean percent P-Selectin externalization for WB, PRP, and PRP with thrombin was 25.5 ± 30.9, 4.5 ± 6.4, and 90.6 ± 4.4 respectively.Clinical significance: Cellular reproducibility of this kit was confirmed and platelets were concentrated within autologous serum. Additionally, measurements of P-selectin externalization showed that platelets are inactive in PRP unless stimulated to degranulate.

Authors: Oheida Aiman , Philip Christopher , Yen Hung-Hsun , Davies Helen 
Published: November 2015

SummaryObjectives: To describe the incidence and forms of nonpathological sacrocaudal fusion in racing Greyhounds and compare them with those in a variety of other domestic dog breeds.Methods: This retrospective observational study used archived anatomical specimens from 81 racing Greyhounds and 10 Beagles, and archived clinical radiographs from 81 non-Greyhound dogs representing 37 other breeds. Dogs less than two years of age and dogs with evidence of soft tissue or osseous pathology involving the sacrocaudal region were excluded. The incidence of osseous sacrocaudal fusion (any type and complete fusion) was compared between Greyhounds and all of the other dogs combined, using the Fisher's exact test.Results: Sacrocaudal fusion of some type was found in 33 (41%) of 81 Greyhounds but in only 14 (15%) of 91 non-Greyhound dogs (p <0.01). Complete fusion (osseous fusion of vertebral bodies and both transverse and articular processes) between the sacrum and the first caudal vertebra was the most common form in Greyhounds, found in 27 (33%) of 81 Greyhounds, but in only three (3.3%) of 91 non-Greyhound dogs (p <0.01).Clinical significance: Sacrocaudal fusion appears to be more prevalent in Greyhounds than in other domestic dog breeds and may be attributable to selection pressure for speed on a region of the spine that is naturally prone to variation. Its significance for performance and soundness requires further study.
Southern Ocean Asteroidea: a proposed update for the Register of Antarctic Marine Species
Authors: Moreau Camille , Aguera Antonio , Jossart Quentin , Danis Bruno 
Published: November 2015

The Register of Antarctic Marine Species (RAMS, De Broyer et al. 2015) is the regional component of the World Register of Marine Species (WoRMS Editorial Board 2015) in the Southern Ocean. It has been operating for the last ten years, with a special effort devoted towards its completion after the International Polar Year (IPY) in 2007-2008, in the framework of the Census of Antarctic Marine Life (CAML, 2005 - 2010). Its objective is to offer free and open access to a complete register of all known species living in the Southern Ocean, building a workbench of the present taxonomic knowledge for that region. The Antarctic zone defined by this dynamic and community-based tool has been investigated with a particular interest. The Sub-Antarctic zone was a secondary objective during the establishment of the RAMS and is still lacking the impulse of the scientific community for some taxa.
In the present study, more than 13,000 occurrences records of Asteroidea (Echinodermata) have been compiled within the RAMS area of interest and checked against the RAMS species list of sea stars, using WoRMS Taxon Match tool. Few mismatches (basionym mistakes : i.e. original name misspelled or incorrect) were found within the existing list and 97 unregistered species are actually occurring within the RAMS boundaries. After this update, the number of Asteroidea species was increased by around 50%, now reaching 295 accepted species.
