Published: June 2014

Abstract
Background and Aims. Scientists are constantly showing a high interest for the relationship between Periodontal Disease (PD) and Diabetes Mellitus (DM). PD, “the sixth complication” of DM is recognized to be a chronic gram-negative anaerobic infectious disease. This paper is aimed at reviewing and evaluating the correlations between PD and DM from a microbiological point of view. Treatment implications of PD’s management as an important component of DM care is reviewed in the light of microbiological current knowledge. Materials and Methods. Microbiological studies and clinical trials were selected from medical and dental journals, and studied thoroughly. Results. Plaque biofilm and prolonged hyperglycemia increase the risk of PD development in DM. These two features determine inflammatory reactions that end-up in tissue destruction and impaired healing responses. Few pathogens are considered highly prevalent periodontal pathogens, with destructive actions. Studies have shown that metabolic balance or lack of balance determines bacterial variations in diabetic patients with PD. Other results demonstrate the importance of microbial tests (especially PCR techniques) as indicators for healing or disease progression. Conclusions. There aren’t many studies assessing the relationship between PD and DM from microbiological points of view. In light of increasing evidence, larger interventional studies are needed
Near viability for fully nonlinear differential inclusions
Authors: Căpraru Irina , Lazu Alina 
Published: June 2014

AbstractWe consider the nonlinear differential inclusion x′(t) ∈ Ax(t) + F(x(t)), where A is an m-dissipative operator on a separable Banach space X and F is a multi-function. We establish a viability result under Lipschitz hypothesis on F, that consists in proving the existence of solutions of the differential inclusion above, starting from a given set, which remain arbitrarily close to that set, if a tangency condition holds. To this end, we establish a kind of set-valued Gronwall’s lemma and a compactness theorem, which are extensions to the nonlinear case of similar results for semilinear differential inclusions. As an application, we give an approximate null controllability result.

Published: June 2014

AbstractPyatov’s method has been applied to investigate Fermi beta transitions in deformed 74–80Kr isotopes. This self-consistent method, which was used to study the isobar analogue states in the spherical odd-odd nuclei, has to date not been applied for the isobar analogue states in deformed nuclei. The nucleon-nucleon residual interaction has been included so that the broken isospin symmetry in the mean field approximation has been restored and the strength parameter of the effective interaction has been taken out to be a free parameter. The energies and wave functions of the isobaric analogue excitations in 74–80Rb isotopes have been obtained within the framework of the pnQRPA method. The probability of the isospin mixing in the ground states and the centroid energies of the isobar analogue resonance have been presented and the deformation effects on these quantities have been quantified.

Published: June 2014

Object
Cell therapy is a promising candidate among biological or technological innovations sought to augment microsurgical techniques in peripheral nerve repair. This report describes long-term functional regenerative effects of cell therapy in the rat injury model with a focus on sensory recovery.

Methods
Schwann cells were derived from isogenic nerve or skin precursor cells and injected into the transected and immediately repaired sciatic nerve distal to the injury site. Sensory recovery was assessed at weeks 4, 7, and 10. Axonal regeneration was assessed at Week 11.

Results
By Week 10, thermal sensitivity in cell therapy groups returned to a level indistinguishable from the baseline (p > 0.05). Immunohistochemistry at 11 weeks after injury showed improved regeneration of NF+ and IB4+ axons.

Conclusions:
The results of this study show that cell therapy significantly improves thermal sensation and the number of regenerated sensory neurons at 11 weeks after injury. These findings contribute to the view of skin-derived stem cells as a reliable source of Schwann cells with therapeutic potential for functional recovery in damaged peripheral nerve.
Case-control studies in neurosurgery
Authors: Nesvick Cody L. , Thompson Clinton J. , Boop Frederick A. , Klimo Paul 
Published: June 2014

Object
Observational studies, such as cohort and case-control studies, are valuable instruments in evidence-based medicine. Case-control studies, in particular, are becoming increasingly popular in the neurosurgical literature due to their low cost and relative ease of execution; however, no one has yet systematically assessed these types of studies for quality in methodology and reporting.

Methods
The authors performed a literature search using PubMed/MEDLINE to identify all studies that explicitly identified themselves as “case-control” and were published in the JNS Publishing Group journals (Journal of Neurosurgery, Journal of Neurosurgery: Pediatrics, Journal of Neurosurgery: Spine, and Neurosurgical Focus) or Neurosurgery. Each paper was evaluated for 22 descriptive variables and then categorized as having either met or missed the basic definition of a case-control study. All studies that evaluated risk factors for a well-defined outcome were considered true case-control studies. The authors sought to identify key features or phrases that were or were not predictive of a true case-control study. Those papers that satisfied the definition were further evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist.

Results
The search detected 67 papers that met the inclusion criteria, of which 32 (48%) represented true case-control studies. The frequency of true case-control studies has not changed with time. Use of odds ratios (ORs) and logistic regression (LR) analysis were strong positive predictors of true case-control studies (for odds ratios, OR 15.33 and 95% CI 4.52–51.97; for logistic regression analysis, OR 8.77 and 95% CI 2.69–28.56). Conversely, negative predictors included focus on a procedure/intervention (OR 0.35, 95% CI 0.13–0.998) and use of the word “outcome” in the Results section (OR 0.23, 95% CI 0.082–0.65). After exclusion of nested case-control studies, the negative correlation between focus on a procedure/intervention and true case-control studies was strengthened (OR 0.053, 95% CI 0.0064–0.44). There was a trend toward a negative association between the use of survival analysis or Kaplan-Meier curves and true case-control studies (OR 0.13, 95% CI 0.015–1.12). True case-control studies were no more likely than their counterparts to use a potential study design “expert” (OR 1.50, 95% CI 0.57–3.95). The overall average STROBE score was 72% (range 50–86%). Examples of reporting deficiencies were reporting of bias (28%), missing data (55%), and funding (44%).

Conclusions
The results of this analysis show that the majority of studies in the neurosurgical literature that identify themselves as “case-control” studies are, in fact, labeled incorrectly. Positive and negative predictors were identified. The authors provide several recommendations that may reverse the incorrect and inappropriate use of the term “case-control” and improve the quality of design and reporting of true case-control studies in neurosurgery.
Geochemical Characteristics and Genesis for Volcanic Rocks of Yixian Formation in Western Liaoning Province
Authors: Peng Yan Dong , Yu Chun Yun , Bian Xiong Fei 
Published: June 2014

Volcanic rocks of Yixian Formation were widely distributed in western Liaoning. The Yixian volcanic cycle of early Cretaceous in the Chaoyang basin can be divided into two subcycles. The first subcycle is composed of basalt, basalt andesite and andesite. The second subcycle is composed of trachyandensite and trachyte. The volcanic rocks are characterized by high SiO2, Al2O3, K2O and Na2O, and comparatively low TiO2 components. The volcanic rocks are obviously enriched in incompatible elements, and depleted in compatible elements. The ∑REE of volcanic rocks is high and rich in LREE. The spider patterns are the right-incline, there is a slight low Eu negative abnormality and low Ce negative abnormality. The characteristics show that volcanic rocks of Yixian Formation belong to the high-K calc-alkaline magmatic serious. Comprehensive study shows that the volcanic rocks of Yixian Formation were generated in response to lithosphere extension in the continent intraplate orogenic belt.
School personnel’s perceptions of their schools’ involvement in culturally and linguistically diverse school-family-community partnerships
Authors: Jonak Jolanta 
Published: June 2014

<b>BACKGROUND</b><br />
The achievement gap between White and culturally and linguistically diverse (CLD) students is a chronic issue in many U.S. schools that stakeholders endeavor to eliminate through best practices involving curriculum, instruction, and early interventions; however, disparities often persist. In addition to all educational efforts provided by schools and implementation of best practices when students begin to struggle academically or behaviorally in schools, family involvement cannot be disregarded.<br />
<b>PARTICIPANTS AND PROCEDURE</b><br />
School personnel from one Midwestern school district in the United States educating over 8,000 students was surveyed to obtain their perceptions about school-family-community partnerships. A total of 117 informants, including teachers, student support personnel, and administrators, provided their opinions through an online survey measuring responses to questions related to current best practices in their schools with regard to culturally and linguistically diverse students, their families and their communities.<br />
<b>RESULTS</b><br />
In a research study focused on school practices relating to parent involvement, it was found that strategies intended to encourage and incorporate parent involvement were implemented in just one-third to one-half of the schools surveyed, indicating the need for increased and concerted effort on the part of school professionals to recognize and address obstacles to a pivotal school-parent-community relationship.<br />
<b>CONCLUSIONS</b><br />
Although schools can be credited with endeavoring to provide best practices for their CLD students, in keeping with state and federal mandates and assumedly in keeping with best intentions, there is in fact much work to be done to better facilitate the success of these students. School psychologists can provide the impetus for this effort by formally recommending parent involvement and participation in their assessments of CLD students in particular. This recommendation should inherently include awareness and consideration of cultural preconceptions that may hinder parent involvement.
New aspects of spondyloarthritis pathogenesis. Part I. Genetic factors and role of HLA-B27 molecules
Authors: Kontny Ewa 
Published: June 2014

Badania z ostatnich lat weryfikują zrozumienie patogenezy spondyloartropatii zapalnych (SpA). Wskazują one, że tradycyjne podtypy tej choroby mają wspólny komponent patogenezy. Składają się na niego pewne wspólne uwarunkowania genetyczne (allele HLA-B27, warianty genów IL-23R, ERAP1, ERAP2), które omówiono w niniejszym artykule. Oprócz tego istnieją podobieństwa dotyczące czynników środowiskowych i mechanizmów immunologicznych, co będzie przedmiotem następnych opracowań. Zmienił się również pogląd na rolę cząsteczek HLA-B27 w patogenezie SpA. Cząsteczki HLA-B27 występują w formie klasycznej i nieklasycznej, jako pojedyncze łańcuchy ciężkie lub ich homodimery. Cząsteczki klasyczne prezentują antygeny własne i obce, inicjując nabytą odpowiedź immunologiczną, natomiast cząsteczki nieklasyczne indukują odpowiedź autozapalną. W artykule omówiono również to zagadnienie.

Published: June 2014

Dialogar sobre a relação existente entre Geografia, cidade e lugar enriquece o processo de ensino-aprendizagem, considerando a cidade na qual residem os alunos como um palco para a produção do conhecimento. Assim, este trabalho tem como finalidade refletir sobre a importância da valorização da cidade e do espaço vivido pelo aluno no processo ensino-aprendizagem e averigua as concepções que educadores têm a respeito da cidade de Formosa-GO como palco da aprendizagem. A cidade de Formosa-GO, com mais de 100.000 habitantes e 170 anos de história, com seus festejos, manifestações culturais e religiosas, com seus recursos naturais exuberantes, mas também, com problemas e situações peculiares de uma cidade que se desenvolve, detém locais que podem ser assumidos como uma sala de aula. Fazer da cidade uma proposta pedagógica é um desafio, porém necessário quando se quer partir do mundo vivido do discente para que a aprendizagem torne-se significativa. Explorar espaços que rodeiam a escola que são vistos pelos alunos do caminho de casa para escola leva as alunos a conhecerem, intervir e (re) criar a sua cidade.DOI: 10.5216/rir.v1i16.28700
Le Canada et l’austérité expansionniste dans les années quatre-vingt-dix : un « succès » macroéconomique à revisiter ?
Authors: Charles Sébastien , Dallery Thomas 
Published: June 2014

Dans cet article nous étudions l’évolution et la soutenabilité de l’endettement public au Canada à l’aide de la méthodologie comptable proposée par Pasinetti (1998). Nous montrons dans quelle mesure la politique d’austérité décidée par le gouvernement canadien lors de la première moitié des années quatre-vingt-dix a pu faire croire à ce que certains économistes nomment l’austérité expansionniste. Ainsi, nous dévoilons un large faisceau de circonstances « bienheureuses » ayant empêché une récession économique. Au regard de ces différents éléments, nous précisons pourquoi le Canada ne devrait pas constituer un exemple à suivre aveuglément en matière de consolidation budgétaire.
Calibration of sea ice dynamic parameters in an ocean‐sea ice model using an ensemble Kalman filter
Authors: Massonnet F. , Goosse H. , Fichefet T. , Counillon F. 
Published: June 2014

AbstractThe choice of parameter values is crucial in the course of sea ice model development, since parameters largely affect the modeled mean sea ice state. Manual tuning of parameters will soon become impractical, as sea ice models will likely include more parameters to calibrate, leading to an exponential increase of the number of possible combinations to test. Objective and automatic methods for parameter calibration are thus progressively called on to replace the traditional heuristic, “trial‐and‐error” recipes. Here a method for calibration of parameters based on the ensemble Kalman filter is implemented, tested and validated in the ocean‐sea ice model NEMO‐LIM3. Three dynamic parameters are calibrated: the ice strength parameter P*, the ocean‐sea ice drag parameter Cw, and the atmosphere‐sea ice drag parameter Ca. In twin, perfect‐model experiments, the default parameter values are retrieved within 1 year of simulation. Using 2007–2012 real sea ice drift data, the calibration of the ice strength parameter P* and the oceanic drag parameter Cw improves clearly the Arctic sea ice drift properties. It is found that the estimation of the atmospheric drag Ca is not necessary if P* and Cw are already estimated. The large reduction in the sea ice speed bias with calibrated parameters comes with a slight overestimation of the winter sea ice areal export through Fram Strait and a slight improvement in the sea ice thickness distribution. Overall, the estimation of parameters with the ensemble Kalman filter represents an encouraging alternative to manual tuning for ocean‐sea ice models.
Composition and flux of explosive gas release at LUSI mud volcano (East Java, Indonesia)
Authors: Vanderkluysen Loÿc , Burton Michael R. , Clarke Amanda B. , Hartnett Hilairy E. , Smekens Jean‐François 
Published: June 2014

AbstractThe LUSI mud volcano has been erupting since May 2006 in the densely populated Sidoarjo regency (East Java, Indonesia), forcing the evacuation of 40,000 people and destroying industry, farmland, and over 10,000 homes. Mud extrusion rates of 180,000 m3 d−1 were measured in the first few months of the eruption, decreasing to a loosely documented <20,000 m3 d−1 in 2012. The last few years of activity have been characterized by periodic short‐lived eruptive bursts. In May and October 2011, we documented this activity using high‐resolution time‐lapse photography, open‐path FTIR, and thermal infrared imagery. Gases (98% water vapor, 1.5% carbon dioxide, 0.5% methane) were periodically released by the bursting of bubbles approximately 3 m in diameter which triggered mud fountains to ∼10 m and gas plumes to hundreds of meters above the vent. During periods of quiescence (1–3 min), no appreciable gas seepage occurred. We estimate that LUSI releases approximately 2300 t yr−1 of methane, 30,000 t yr−1 of CO2, and 800,000 t yr−1 of water vapor. Gas bubble nucleation depths are >4000 m for methane and approximately 600 m for carbon dioxide; however, the mass fractions of these gases are insufficient to explain the observed dynamics. Rather, the primary driver of the cyclic bubble‐bursting activity is decompressional boiling of water, which initiates a few tens of meters below the surface, setting up slug flow in the upper conduit. Our measured gas flux and conceptual model lead to a corresponding upper‐bound estimate for the mud‐water mass flux of 105 m3 d−1.
Momentum balance of katabatic flow on steep slopes covered with short vegetation
Authors: Oldroyd Holly J. , Katul Gabriel , Pardyjak Eric R. , Parlange Marc B. 
Published: June 2014

AbstractKatabatic flows over alpine mountainous terrain differ from their forested or bare slope counterparts due to the presence of well‐ventilated, short vegetation. The impact of a grass canopy and larger‐scale pressure perturbations on the one‐dimensional mean momentum balance is explored via theory and field measurements. The model presented here reproduces the measured velocity jet shape and turbulent flux gradients. These two features imply that even when Monin‐Obuhkov similarity theory breaks down, its use for a stability adjusted mixing length remains effective to first order. Results reveal that outer layer pressure effects can be significant under low‐speed wind conditions at the top of the thin katabatic layer when larger variations in the wind direction are observed. An analytical expression to estimate the jet height, which can be utilized in large‐scale weather prediction models, shows the importance of including canopy effects for the thin katabatic flow region above the vegetation.
A surfzone morphological diffusivity estimated from the evolution of excavated holes
Authors: Moulton Melissa , Elgar Steve , Raubenheimer Britt 
Published: June 2014

AbstractDownslope gravity‐driven sediment transport smooths steep nearshore bathymetric features, such as channels, bars, troughs, cusps, mounds, pits, scarps, and bedforms. Downslope transport appears approximately as a diffusive term in the sediment continuity equation predicting changes in bed level, with a morphological diffusivity controlling the rate of seafloor smoothing. Despite the importance of surfzone sediment transport and morphological evolution, the size of the downslope transport term in nearshore models varies widely, and theories have not been tested with field measurements. Here observations of the infill of large excavated holes in an energetic inner surf zone provide the first opportunity to infer the morphological diffusivity in the field. The estimated diffusion coefficient is consistent with a theoretical bedload morphological diffusivity that scales with the three‐halves power of the representative bed shear stress.
Volatility dependence of Henry's law constants of condensable organics: Application to estimate depositional loss of secondary organic aerosols
Authors: Hodzic A. , Aumont B. , Knote C. , Lee‐Taylor J. , Madronich S. , Tyndall G. 
Published: June 2014

AbstractThe water solubility of oxidation intermediates of volatile organic compounds that can condense to form secondary organic aerosol (SOA) is largely unconstrained in current chemistry‐climate models. We apply the Generator of Explicit Chemistry and Kinetics of Organics in the Atmosphere to calculate Henry's law constants for these intermediate species. Results show a strong negative correlation between Henry's law constants and saturation vapor pressures. Details depend on precursor species, extent of photochemical processing, and NOx levels. Henry's law constants as a function of volatility are made available over a wide range of vapor pressures for use in 3‐D models. In an application using the Weather Research and Forecasting model coupled with Chemistry (WRF‐Chem) over the U.S. in summer, we find that dry (and wet) deposition of condensable organic vapors leads to major reductions in SOA, decreasing surface concentrations by ~50% (10%) for biogenic and ~40% (6%) for short chain anthropogenic precursors under the considered volatility conditions.
Underpinning tectonic reconstructions of the western Mediterranean region with dynamic slab evolution from 3‐D numerical modeling
Authors: Chertova M. V. , Spakman W. , Geenen T. , van den Berg A. P. , van Hinsbergen D. J. J. 
Published: June 2014

AbstractNo consensus exists on the tectonic evolution of the western Mediterranean since ~35 Ma. Three disparate tectonic evolution scenarios are identified, each portraying slab rollback as the driving mechanism but with rollback starting from strongly different subduction geometries. As a critical test for the validity of each tectonic scenario we employ thermomechanical modeling of the 3‐D subduction evolution. From each tectonic scenario we configure an initial condition for numerical modeling that mimics the perceived subduction geometry at ~35 Ma. We seek to optimize the fit between observed and predicted slab morphology by varying the nonlinear viscoplastic rheology for mantle, slab, and continental margins. From a wide range of experiments we conclude that a tectonic scenario that starts from NW dipping subduction confined to the Balearic margin at ~35 Ma is successful in predicting present‐day slab morphology. The other two scenarios (initial subduction from Gibraltar to the Baleares and initial subduction under the African margin) lead to mantle structure much different from what is tomographically imaged. The preferred model predicts slab rotation by more than 180°, east‐west lithosphere tearing along the north African margin and a resulting steep east dipping slab under the Gibraltar Strait. The preferred subduction model also meets the first‐order temporal constraints corresponding to Mid‐Miocene (~16 Ma) thrusting of the Kabylides onto the African margin and nearly stalled subduction under the Rif‐Gibraltar‐Betic arc since the Tortonian (~8 Ma). Our modeling also provides constraints on the rheological properties of the mantle and slab, and of continental margins in the region.
