Authors: Mishra Vineet , Aggarwal Rohina , Nanda Sakshi , Gandhi Khushali , Bandwal Pradeep , Nawal Rajani 
Published: August 2017

ABSTRACT
Congenital absence of cervix is a rare condition that occurs in 1 in 80,000 to 100,000 births. Here, we report a case of a 20-year-old, married woman who presented to the gynecology outpatient department with primary amenorrhea and complaints of cyclical left-sided lower abdominal pain and difficult coitus for 2 years. Magnetic resonance imaging report suggested unicornuate uterus with hematometra and cervical agenesis. On laparotomy, unicornuate globular uterine horn with absent cervix was present on the left side and separate solid rudimentary horn was found on right lateral pelvic wall. Left adnexa was normal, whereas right ovary was enlarged with minimal hydrosalpinx. Vaginoplasty with uterovaginal anastomosis was performed after draining the hematometra and successful restoration of cyclical menses was achieved on follow-up.

Selective Uterine Artery Embolization: An Effective Treatment Option for Postpartum Hemorrhage due to Pseudoaneurysm of Uterine Artery
Authors: Gollapudi Radhika , Rammurty S 
Published: August 2017

ABSTRACT

Aim
To demonstrate the efficacy of uterine artery embolization in the management of postpartum hemorrhage (PPH) due to pseudoaneurysm of the uterine artery.

Background
Postpartum hemorrhage is a leading cause of maternal mortality in India. Secondary PPH is a rare cause but potentially life threatening. Common causes of secondary PPH are retained products of conception, subinvolution of uterus, and endometritis. Pseudoaneurysm is an uncommon cause of secondary PPH following operative delivery. Color Doppler ultrasound is a useful diagnostic tool and angiography is necessary to localize and treat by embolization.

Case report
We report two cases of secondary PPH due to pseudoaneurysm of uterine artery, which were managed by selective embolization of uterine artery.

Conclusion
Angiographic embolization of uterine artery is a safe and reliable technique for management of secondary PPH due to pseudoaneurysm. If diagnosed early, the need for hysterectomy is prevented.

Clinical significance
Uterine artery embolization has emerged as a simple, effective, and fertility-sparing treatment for PPH.

Impact of Polishing Systems on the Surface Roughness and Microhardness of Nanocomposites
Authors: Alfawaz Yasser 
Published: August 2017

ABSTRACT

Aim
The aim of this article is to evaluate the influence of finishing and polishing techniques on the surface roughness and microhardness of two composite resins with two different types of polishing systems.

Materials and methods
A total of 30 disk-shaped specimens of nanocomposite Filtek™ Z350 and Ceram-X® were prepared. They were divided into three groups. The control group (n = 10) received no finishing and polishing. The remaining specimens were divided into two groups, and they received polishing and finishing either with PoGo or Sof-Lex system. After the polishing procedures, average surface roughness (Ra) was assessed with a surface profilometer. The microhardness was determined using a Vickers hardness test. The data were tabulated and analyzed.

Results
The smoothest surfaces were noticed with the control group (Mylar strips) in both composite materials tested. The PoGo one-step polishing system showed significantly better surface roughness compared with the Sof-Lex polishing system. The microhardness did not show any significant variations after finishing and polishing.

Conclusion
It can be concluded that the use of PoGo® onestep polishing system resulted in smoother surface with both composite materials studied compared with the Sof-Lex system. The finishing and polishing system had little influence on the surface microhardness.

Clinical significance
The finishing procedure and polishing system can affect the physical properties and performance of resin composites.

Published: August 2017

ABSTRACT

Aims
The aim of this study was to assess the denture hygiene knowledge and practices among patients using complete dentures attending a postgraduate dental hospital in Jabalpur city. The objective of this study was to assess the relationship between hygiene knowledge and practices to the denture wearer's gender, education, and income.

Materials and methods
A descriptive, cross-sectional survey was conducted using a self-administered questionnaire involving the complete denture patients attending the Department of Prosthodontics. The study subjects were randomly selected by recruiting old dentures wearers visiting the Department of Prosthodontics for a recall visit or for new dentures on the odd dates of the month. All subjects signed an informed consent before filling the questionnaire. The institutional review committee approved the study. Descriptive statistics included computation of frequencies and percentages. Nonparametric test, namely, chi-square test, was used for further data analysis; p-value <0.05 was considered statistically significant.

Results
A total of 530 individuals were approached for participation in our survey, 30 (5.66%) subjects declined to participate. The results showed that 195 (39%) subjects were wearing the same dentures for more than 5 years. In this study, 51 (10.2%) subjects reported never having been advised by their dentists as to how to clean their dentures. Among all the subjects interviewed, 264 (52.8%) reported to clean the oral tissues daily. This study disclosed that 66 (13.2%) of the subjects usually slept with their dentures. Maximum subjects in illiterate group had experienced bad breath sometimes when compared with subjects in postgraduate group (χ2 = 47.452, p < 0.001). There was a significant difference for method of denture cleaning according to gender (χ2 = 101.076, p < 0.001).

Conclusion
The majority of the denture wearers have limited knowledge of denture cleansing and oral hygiene practices. Hygiene habits and practices may not always present a positive correlation with the gender, educational level, and income of the subjects.

Clinical significance
Periodic recall for evaluation of denture and mucosal surfaces along with reinforcement of denture hygiene instructions will go a long way in helping the patients reap maximum benefits out of their prostheses.

As perguntas eram todas com alternativas, direcionadas ao consumo de camarão. O trabalho realizado teve como finalidade mostrar aos aquicultores da região Oeste do Paraná, que tem interesse em começar a produzir camarão de água doce na região, uma estimativa do consumo de camarão. Desta forma verificou-se que mais de 70% das pessoas consomem camarão regularmente e que preferem comprar direto do produtor o camarão fresco. Além disso, devido à falta de acessibilidade e baixa qualidade evitam a sua compra em natura em estabelecimentos comerciais. Este estudo de mercado se mostra como uma ferramenta importante para entender o ambiente mercadológico, onde se pretende inserir o camarão, para impulsionar a produção e a comercialização do produto.
Epilepsy Treatment: A Futurist View
Authors: Privitera Michael 
Published: August 2017

Advances in epilepsy treatment are occurring at a rapid pace, and it is challenging for us to keep up with the latest in our field. As we struggle to keep up with the literature and concentrate on our own research and clinical work, we often fail to exercise our imagination and envision what our field will be like in future decades. This was the assignment to the speakers for the Presidential Symposium at the 2016 American Epilepsy Society Annual Meeting. I challenged the experts to step outside the frame of their usual daily work to imagine what epilepsy treatment would and should look like for the next generation of epilepsy specialists and their patients. As you will read in the following sections, the speakers truly stepped up to the challenge to look into the crystal ball. The following are summaries of each lecture that describe the current state, existing cutting edge ideas, and some surprising predictions for the future. I am grateful for the tremendous effort these experts put into this challenge and hope they stimulate your imagination so you will work to bring these advances to our patients.
O EMPREENDEDORISMO SOCIAL COMO POSSIBILIDADE DE CIDADANIA
Authors: Oliveira Émerson Dias de 
Published: August 2017

A chamada sociedade “pós-moderna” está instituída em um contexto social de uma complexidade existencial extremamente complexa, em que as relações sociais são envolvidas por lógicas, interesses e raciocínios deslocados totalmente do bem comum, uma ação arbitrária e particularizada que desconsidera toda e qualquer panorâmica presente no seu entorno, mesmo que ela represente uma pandemia de miserabilidade mundial dos indivíduos. Através da pesquisa bibliográfica, do debate crítico-analítico e uma abordagem exploratório acerca das questões que permeiam a constituição do Empreendedorismo Social, como forma de oportunizar a ver e a voz dos “invisíveis” socialmente, este estudo procura questionar o modelo de sociedade que se tem em curso atualmente. A totalidade vigente não pode se manter, é insustentável a concentração de riqueza nesse “mundo moderno”, cabendo às camadas menos abastadas socialmente se unirem para superar essa problemática e a academia de mostrar-lhes o caminho a ser triado nesse ambiente infestado por “predadores vorazes” do capital.
Connaître et comprendre le passé pour réfléchir au devenir de la société québécoise. La contribution de Serge Gagnon à l’historiographie religieuse
Authors: Hudon Christine 
Published: August 2017

Cet article vise à retracer le parcours de Serge Gagnon et à mettre en lumière l’apport de ses recherches en histoire religieuse, ainsi que les oeuvres et les auteurs qui l’ont influencé. Ses livres, écrits dans un style vivant et accessible, cherchent à reconstituer l’histoire de la pastorale, des moeurs catholiques et des conditions de vie matérielle des prêtres au Bas-Canada à partir d’une analyse qualitative d’un large corpus documentaire. En se fondant sur de nombreux exemples analysés finement, Gagnon montre comment s’exerce le pouvoir du clergé et tente de cerner les raisons qui conduisent les populations à adhérer au message de l’Église. Les ouvrages sont traversés par trois grandes influences : celle de la sociologie de la connaissance, celle de l’historiographie religieuse française et celle de sociologues américains critiques de l’individualisme et de la société de consommation. Ces derniers font écho au regard inquiet que Gagnon pose sur le mode de vie du Québec actuel en l’opposant au régime de moeurs catholique des communautés bas-canadiennes.
Spatial distribution of the most abundant sea urchin populations on the southeast coast of Sao Paulo (Brazil)
Authors: Sánchez-Jérez P , Cesar A , Cortez FS , Pereira CDS , Silva SLR 
Published: August 2017

The spatial variability of Echinometra lucunter, Lytechinus variegatus and Arbacia lixula was studied in relation to four spatial scales (105, 104, 103 and 102 m) and two depths (0–3 and 3–8 m), along 100 km of the São Paulo coastline (August to October 1996). Echinometra lucunter was the most abundant species, with preference for shallow substrates subject to wave action. An abundance gradient was identified, increasing from southwest to northeast. Arbacia lixula showed the same pattern of spatial variation, but was more abundant in the deeper areas. Both species showed significant differences on a spatial scale of hundreds of meters, and E. lucunter also on a scale of kilometers. Lytechinus variegates presented a patchy distribution, being more abundant at certain sites. Variations in the water quality and natural heterogeneity of the habitat may explain the spatial distribution of these populations.
The mechanisms underpinning Cenozoic intraplate volcanism in eastern Australia: Insights from seismic tomography and geodynamic modeling
Authors: Rawlinson N. , Davies D. R. , Pilia S. 
Published: August 2017

AbstractCenozoic intraplate volcanism is widespread throughout much of eastern Australia and manifests as both age‐progressive volcanic tracks and non‐age‐progressive lava fields. Various mechanisms have been invoked to explain the origin and distribution of the volcanism, but a broad consensus remains elusive. We use results from seismic tomography to demonstrate a clear link between lithospheric thickness and the occurrence, composition, and volume of volcanic outcrop. Furthermore, we find that non‐age‐progressive lava fields overlie significant cavities in the base of the lithosphere. Based on numerical simulations of mantle flow, we show that these cavities generate vigorous mantle upwellings, which likely promote decompression melting. However, due to the intermittent nature of the lava field volcanics over the last 50 Ma, it is probable that transient mechanisms also operate to induce or enhance melting. In the case of the Newer Volcanics Province, the passage of a nearby plume appears to be a likely candidate. Our results demonstrate why detailed 3‐D variations in lithospheric thickness, plate motion, and transient sources of mantle heterogeneity need to be considered when studying the origin of non age‐progressive volcanism in continental interiors.
Hyaluronic Acid Microgels Modulate Inflammation and Key Matrix Molecules toward a Regenerative Signature in the Injured Annulus Fibrosus
Authors: Kazezian Zepur , Sakai Daisuke , Pandit Abhay 
Published: August 2017

AbstractLow back pain results from disc degeneration, which is a chronic inflammatory disease characterized by an imbalance between anabolic and catabolic factors. Today, regenerative medicine is focused on identifying inflammatory markers to target disc disease. Hyaluronan is used as a scaffold for cell delivery in disc degeneration; however, to date high molecular weight hyaluronan (HMW HA) is evaluated for its anti‐inflammatory and matrix modulatory properties in an in vivo disc injury model. Ex vivo bovine organ culture studies demonstrate the anti‐inflammatory and matrix modulatory effects of HMW HA on the IFNα2β signaling pathway that provides the motivation for evaluating its efficacy in regenerating the annulus fibrosus in an in vivo disc injury model. It is demonstrated that the HMW HA microgel acts as an anti‐inflammatory molecule in the annulus fibrosus, by downregulating the expression of the pro‐inflammatory interferon gamma (IFNα) and pro‐apoptotic insulin‐like growth factor‐binding protein 3 (IGFBP3) and the apoptosis marker caspase 3. Mass spectrometry studies demonstrate that the HMW HA microgel modulates the matrix modulatory effect by upregulating hyaluronic acid link protein (HAPLN1) and aggrecan, which are further confirmed by immunostaining. The microgel's regenerative capacity is illustrated by the increase in the disc height index.

Authors: Chen Li‐Feng , Feng Yue , Liang Hai‐Wei , Wu Zhen‐Yu , Yu Shu‐Hong 
Published: August 2017

AbstractThe development of high‐performance electrochemical energy storage devices is critical for addressing energy crises and environmental pollution. Hence, the design and preparation of next‐generation electrode materials have been gaining increasing attention. Recent progress has demonstrated that three‐dimensional (3D) carbon nanomaterials are extremely promising candidates for the electrodes of electrochemical energy storage devices due to their unique structural advantages of interlinked architecture. Herein, recent advances in the scalable fabrication of 3D carbon nanofiber (CNF)‐based materials and their applications for electrochemical energy storage devices are summarized. Some representational 3D CNF architectures, such as CNF gels, 3D CNF films, 3D CNF arrays, and their nanocomposites, are highlighted with regard to various applications, including supercapacitors, lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), lithium–sulfur (Li–S), lithium–selenium (Li–Se), and metal–O2 batteries, as well as other new battery systems. Finally, contemporary challenges in the scalable fabrication of 3D CNF architectures are outlined and a brief outlook to future studies is given. This review illustrates significant opportunities for the macroscopic fabrication of 3D CNF architectures, and therefore inspires new discoveries to promote the practical applications of 3D CNF architectures in electrochemical energy storage fields.
A Silicon Ratchet to Produce Power from Below‐Bandgap Photons
Authors: Lau Bryan , Kedem Ofer , Kodaimati Mohamad , Ratner Mark A. , Weiss Emily A. 
Published: August 2017

AbstractThis paper computationally demonstrates a new photovoltaic mechanism that generates power from incoherent, below‐bandgap (THz) excitations of conduction band electrons in silicon. A periodic sawtooth potential, realized through elastic strain gradients along a 100 nm thick Si slab, biases the oscillatory motion of excited electrons, which preferentially jump and relax into the adjacent period on the right to generate a net current. The magnitude of the ratchet current increases with photon energy (20, 50, and 100 meV) and irradiance (≈MW cm−2), which control the probability of photon scattering, and peaks as a function of the well depth of the ratchet potential, and the dominant mode of energy loss (the 62 meV intervalley phonon). The internal power conversion efficiency of the ratchet has a maximum of 0.0083% at a photon energy of 100 meV, due to inefficiencies caused by isotropic scattering. This new photovoltaic mechanism uses wasted below‐bandgap absorptions to enhance the directional diffusion of charge carriers and could be used to augment the efficiency of traditional photovoltaics.
Organozinc‐Mediated Direct C−C Bond Formation via C−N Bond Cleavage of Ammonium Salts
Authors: Wang Dong‐Yu , Morimoto Koki , Yang Ze‐Kun , Wang Chao , Uchiyama Masanobu 
Published: August 2017

AbstractWe report a direct cross‐coupling reaction between diarylzinc (Ar2Zn) and aryltrimethylammonium salts (ArNMe3+⋅−OTf) in the presence of LiCl, via C−N bond cleavage. The reaction takes place smoothly upon heating in THF without any external catalyst, enabling an efficient and chemoselective formation of biaryl products. Mechanistic studies indicate that the reaction proceeds through a single electron transfer route.
Depletion of HOXA5 inhibits the osteogenic differentiation and proliferation potential of stem cells from the apical papilla

Published: August 2017

AbstractMesenchymal stem cells (MSCs) are a prospective cell source for tissue regeneration due to their self‐renewal abilities and potential to differentiate into different cell lineages, but the molecular mechanisms of the directed differentiation and proliferation are still unknown. Recently, multiple studies have indicated the crucial role of HOX genes in MSC differentiation and proliferation. However, the role of HOXA5 in MSCs remains unknown. Here, we investigated HOXA5 function in stem cells from the apical papilla (SCAPs). After HOXA5 depletion, the results showed a significant decrease in ALP activity and a weakened mineralization ability of SCAPs. The real‐time RT‐PCR results showed prominently lessened expression of OPN and BSP. The CCK8 and CFSE results displayed inhibited proliferation of SCAPs, and flow cytometry assays revealed arrested cell cycle progression at the S phase. Furthermore, we found that depletion of HOXA5 upregulated p16INK4A and p18INK4C and downregulated the Cyclin A. Our research demonstrated that depletion of HOXA5 inhibited osteogenic differentiation and repressed cell proliferation by arresting cell cycle progression at the S phase via p16INK4A, p18INK4C, and Cyclin A in SCAPs, indicating that HOXA5 has a significant role in maintaining the proliferation and differentiation potential of dental‐tissue‐derived MSCs.
Subcritical water hydrolysis of nylon 6 extract concentrate
Authors: Qin Chun Xi , Lin Cheng , Tang Jie , Xi Zhen Hao , Zhao Ling 
Published: August 2017

AbstractNylon 6 extract concentrate, namely, wastewater produced from industrial nylon 6 extraction unit, was hydrolyzed in subcritical water to efficiently decrease the cyclic dimer (CD) content. The CD equilibrium conversion reached a maximum when the initial water content ranged from 0.40 to 0.45 g/g; specifically, a CD conversion of 94.3 % was achieved at the hydrolysis temperature of 543 K and an initial water content of 0.40 g/g. A kinetic model including both acid‐ and base‐catalyzed mechanisms was developed. The model predictions were in good agreement with the experimental results. The hydrolysis reaction constants increased significantly with increasing subcritical water content. By considering the effects of subcritical water on the individual reaction constants, the kinetic model could reproduce the experimental results over a wide range of initial water contents. Hopefully, the developed kinetic model will be applied in the design of a novel nylon 6 extract liquor recycling process.
Synthesis of spherical structured catalysts by dip‐coating: Application to n‐butane dehydrogenation
Authors: Ballarini Adriana , Bocanegra Sonia , de Miguel Sergio , Zgolicz Patricia 
Published: August 2017

AbstractThis work analyzes the deposition conditions of thin layers of γ‐Al2O3 by dip‐coating on a spherical substrate of α‐Al2O3 spheres. Results showed that under controlled deposition conditions, a structured support of α‐Al2O3 spheres coated by a uniform γ‐Al2O3 layer (thickness ≈ 15 µm) of good adherence can be attained. Optimal preparation conditions for the coating, that involved pretreatment of the substrate, gel formation, deposition conditions, and thermal treatments, were obtained. Pt catalysts supported on this structured material can be used as promising dehydrogenation systems. In this sense, a monometallic structured catalyst showed both good metallic dispersion and catalytic performance in n‐butane dehydrogenation reaction compared to another conventional catalytic system.
