BACKGROUND

Mobile applications (apps) that offer various techniques to improve stuttering have flourished the digital marketplace. In evidence-based clinical practice, speech therapists will recommend audio-enriched mobile apps to individuals with stuttering problems based on empirical research evidence. Unfortunately, many developers of stuttering mobile apps have overlooked a substantial research base before the apps become available in the market. Hence, speech therapists necessitate a guideline to assess the quality of a stuttering mobile app before recommending the app to stutterers.

OBJECTIVE

The study aims to develop a rubric intended to be an instrument to assess the quality of stuttering mobile apps in helping speech therapists to make appropriate recommendations on stuttering mobile apps as an assistive technology to support stuttering treatments and therapies.

METHODS

In the study, three rubric development phases are involved: a review of the literature, an online expert survey, and a focus group discussion. In Phase 1, a thorough review of the literature is carried out in search of the criteria of a quality m-health. Strong theoretical grounds and empirical works are the basis of the criteria identification, resulting in a total of 45 criteria are extracted. In Phase 2, an online survey questionnaire designed to establish content validity for each criterion is distributed with seven speech therapists and a researcher in speech disfluency participate in the rating process of each criterion critical for a stuttering mobile app. In Phase 3, a focus group discussion aims to jointly develop a rubric serving as a tool to assess stuttering m-health apps quality.

RESULTS

Each criterion of the 45 evaluative dimensions is rated based on the experts’ experience and knowledge in using assistive mobile apps in conducting a therapy with stutterers under their care. These ratings are collected and analyzed. The validity of each criterion based on the ratings collected is identified through the Content Validity Ratio (CVR). The outcome of this study is a rubric designed with four categories and 18-evaluative dimensions tailored to analyze the quality of stuttering mobile apps. The stuttering mobile app assessment rubric serves multiple purposes, chiefly as an evaluation instrument, providing guidelines for developing stuttering mobile apps and creating a standard form that the professionals working with speech disfluency individuals can utilize to facilitate a collective effort.

CONCLUSIONS

The study has included evidence-based research determined based on health practitioners’ feedbacks for the development of rubric in assessing the stuttering mobile apps quality. This final rubric offers guidance for future development of evidence-based and theoretically grounded stuttering mobile apps.

Excess weight is a major risk factor for chronic diseases. In Australia, over 60% of adults are overweight or obese. The overconsumption of energy-dense nutrient-poor (EDNP) foods and low physical activity (PA) levels are key factors contributing to population obesity. New cost-effective approaches to improve population diet and PA behaviors are needed. This 1-year randomized controlled trial (6-month intervention and 6-month follow-up) aims to investigate whether a tailored intervention using mobile technology can improve diet and PA behaviors leading to weight loss in adults (aged 18-65 years) who are overweight or obese and recruited through a social marketing campaign (LiveLighter). All eligible participants will provide data on demographics and lifestyle behaviors online at baseline, 6 months, and 12 months. Using two-stage randomization, participants will be allocated into one of three conditions (n=200 per group): tailored feedback delivered via email at seven time points, informed by objective dietary (mobile food record app) and activity (wearable activity monitor) assessment; active control receiving no tailored feedback, but undergoing the same objective assessments as tailored feedback; and online control receiving no tailored feedback or objective assessments. Primary outcome measures at 6 and 12 months are changes in body mass, EDNP food and beverage consumption, and daily moderate-to-vigorous PA (measured via accelerometry). Secondary outcomes include change in fruit and vegetable consumption, daily sedentary behaviors, and cost effectiveness. Enrolment commenced in August 2017. Primary outcomes at 12 months will be available for analysis from September 2019. Tailored email feedback provided to individuals may deliver a cost-effective strategy to overcome existing barriers to improving diet and PA. If found to be successful and cost effective, upscaling this intervention for inclusion in larger-scale interventions is highly feasible.

Authors: Ezer Peter , Gergics Marin , Szokodi Istvan , Konyi Attila
Published: November 2020

BACKGROUND

The impact of remote monitoring (RM) in advanced heart failure cardiac implantable electronic device (CIED) patients during COVID-19 lockdown has not been established.

OBJECTIVE

RM can play crucial role in the follow-up of CIED implanted heart failure patients during COVID-19 pandemia.

METHODS

This single centre observational study was aimed to assess follow-up data of 61 remote monitored (RMG) vs. 71 conventional followed (CFG), symptomatic heart failure patients with implantable cardiac defibrillators (ICD) or cardiac resynchronization-therapy (CRT) pacemakers/defibrillators during 6 months of lockdown. The investigation analyzed worsening heart failure, arrhythmia, device related adverse evet rates (primary end point) and hospitalization rates for worsening heart failure (secondary end point).

RESULTS

Although, patients in the RMG had significantly more cardiovascular comorbidities and significantly worse functional class at baseline than CFG patients (NYHA class mean ± SD: [2,74 ± 0,44] vs. [2,34 ± 0,48]; P < .001), there was no difference in the composite end point of worsening heart failure, arrhythmia or device related adverse events. However, RMG patients had relative modest deterioration in heart failure functional class at in-office patient evaluations for worsening heart failure events (∆NYHA mean: 0,8 ; ∆NYHA mean: 1,5 ; P = .026). In addition, patients in RMG were significantly less hospitalized for worsening heart failure (0,0164 event/patient vs. 0,169 event/patient; P = .012).

CONCLUSIONS

: In this observational study remote monitored CIED implanted heart failure patients had significant benefit of lower hospitalization rate for worsening heart failure even on short term follow-up during lockdown.
POST-9/11 TRAUMATIC PARANOIA AS REFLECTED IN DON DELILLO’S FALLING MAN
Authors: Rasad Siti Kurniati , Munjid Achmad
Published: November 2020

This article investigates how the trauma of 9/11 tragedy affects the lives of the characters in DeLillo’s Falling Man and shows how the trauma of 9/11 portrayed in the novel reflects American collective trauma. This investigation is qualitative research utilizing memory and trauma as the theoretical framework. The discussion in this article reveals that individual experience the trauma of 9/11 tragedy differs from one person to another. While other characters go through their mourning successfully, the main character in the novel becomes a perennial mourner and is ceaselessly haunted by his traumatic memory due to constant avoidance from his trauma. His continuous externalization of his trauma causes him to focus on the external threats and becomes a paranoiac. On a societal level, American society is also perpetually mourning and is haunted by post-traumatic paranoia continuously. American exceptionalism, biased orientalist perspective about the orient, and alleged prolonged quasi war between Islam and the west have framed the collective experience of the trauma in binary opposite narrative of a good versus evil war. The collective trauma perpetuates and many policies are born out of their paranoia.Keywords: 9/11 tragedy; memory; mourning; post-traumatic paranoia; trauma

La milpa como modelo para el estudio de la microbiodiversidad e interacciones planta-bacteria
Authors: Gastélum Gabriela , Rocha Jorge
Published: November 2020

La microbiología agrícola busca reemplazar a los agroquímicos por microorganismos o sus productos como agentes de control biológico, debido a que el uso de tecnologías de la revolución verde tiene efectos negativos sobre el ambiente, los productores y sus familias, los consumidores y la salud de los cultivos. Sin embargo, el conocimiento actual acerca de las interacciones benéficas planta-bacteria en ambientes complejos es limitado e insuficiente, para lograr el éxito esperado de los productos biológicos. Las milpas son agroecosistemas tradicionales donde se cultivan diversas variedades de maíz nativo con otras especies asociadas; no se utiliza riego, ni labranza y aunque su aplicación va en aumento, comúnmente no se utilizan agroquímicos; por esto, la milpa representa una fuente de conocimiento sobre prácticas sustentables. Recientemente, se han descrito cambios en las comunidades microbianas de los sistemas agrícolas a causa de la modernización y a la domesticación de las plantas. En la milpa, también se han identificado interacciones benéficas planta-bacteria que parecen haberse perdido en los cultivos modernos. En esta revisión, discutimos las estrategias clásicas y modernas de la microbiología agrícola que pueden ser aplicadas en el estudio de la milpa. El establecimiento de la milpa como modelo de estudio de las interacciones planta-bacteria puede resultar en la generación del conocimiento necesario para disminuir el uso de agroquímicos en los sistemas agrícolas modernos, así como evitar su creciente uso en las milpas.

Published: November 2020

Los desórdenes congénitos de la glicosilación (CDG) son enfermedades poco frecuentes (EPOF) de tipo metabólico y hereditarias que ocurren como consecuencia de mutaciones en los genes que codifican para proteínas que participan, directa o indirectamente, en este proceso. La enfermedad clínicamente denominada Cutis Laxa Autosómica Recesiva tipo II-A (ARCL2A) es un tipo de CDG (ATP6V0A2-CDG) causado por mutaciones en ATP6V0A2, que codifica para la subunidad a2 del dominio v0 de una ATPasa vacuolar que tiene como función el transporte de iones H+ a través de las membranas celulares, regulando así el pH de los compartimentos celulares, e incluye la acidificación del aparato de Golgi. En 2014, nuestro grupo de investigación reportó por primera vez en México, la existencia de dos pacientes con ATP6V0A2-CDG. En este trabajo, se estableció una metodología para identificar a los portadores de la mutación c.187 C>T en el ATP6V0A2 mediante PCR-ARMS.

Published: November 2020

Las levaduras son organismos microscópicos que están distribuidos en toda la Tierra, de modo que algunas han adaptado su metabolismo para proliferar en ambientes extremos. Las levaduras que habitan en la Antártica son un grupo de microorganismos adaptados al frío que han sido poco estudiadas. En esta revisión se describen algunas de las adaptaciones metabólicas que les permiten habitar en ambientes extremos, por ejemplo, el de la Antártica. También se abordan las consideraciones relevantes para saber si una levadura es extremófila, así como los criterios utilizados para clasificar a las levaduras por crecimiento y temperatura. Además, se explica el papel de las vías de biosíntesis de carotenoides y lípidos que están involucradas en contrarrestar a las especies reactivas de oxígeno generadas por estrés oxidante en levaduras pigmentadas y oleaginosas del género Rhodotorula. La revisión también considera aspectos de investigación básica y la importancia de las levaduras oleaginosas de la Antártica para el desarrollo de algunas aplicaciones biotecnológicas.
Disc wall structural abnormalities can act as initiation sites for herniation
Authors: Wade K , Berger-Roscher N , Rasche V , Wilke H
Published: November 2020

Both posture and loading rate are key factors in the herniation process and can determine the failure mechanism of the disc. The influence of disc structure on the herniation process has yet to be directly observed, thus the aim of this study was to test the hypothesis that discs containing greater levels of pre-existing disruption would be more vulnerable to herniation when subjected to severe levels of posture and loading. 30 ovine lumbar motion segments were subjected to combinations of 4 loading conditions (0 - 12° flexion,0 - 9° lateral bending, 0 - 4° axial rotation, 0-1500 N axial compression) for 1000 loading cycles at 2 Hz in a dynamic disc loading simulator. The discs were scanned in an ultra-high field MRI (magnetic resonance imaging, 11.7 T) prior to and following testing. 4 discs herniated and 7 discs suffered nucleus displacement. These discs contained pre-existing defects in the central dorsal annulus. Generally, following testing, discs contained more dorsal annulus disruption, including 7 discs which developed similar characteristic defects although these did not herniate. Overall, more severe complex postures produced more disruption. While more severe postures such as twisting and bending increased disc damage, these results are probably the first directly showing that naturally occurring defects in the disc can act as initiation sites for herniation. The clinical significance of these findings is that, in principle at least, MRI based techniques could be capable of identifying vulnerable discs, with the obvious caveat that further correlation with clinical techniques is required.

Published: November 2020

Indonesian EFL Learners experience erroneous speech in the process of learning the target language. Interlanguage, the errors that contain linguistic features which neither belong to the first language (L1) nor the target language becomes the focus of this study. The study aims to analyze the native and target language influence on the interlanguage produced by the students in their speech production. This study was designed in qualitative research approach. The data was collected through interviewed of 20 eighth grade students in English using a guided interview technique that contains 15 questions. The oral responses produced by the students were recorded, identified, described, and explained. The results show that in the syntactic and lexicon levels, both native and target language influenced the students’ interlanguage production. Native language influence includes 1) the use of Indonesian syntactic pattern; 2) the use of Indonesian acronym; 3) the use of Indonesian words; 4) omission of –s in plural forms; 5) omission of to be; 6) subject deletion; and 7) the use of verbs. Target language influence is observed in overgeneralization of articles, the use of to be, and the overgeneralization of ending –ed in the past tense.
The Communicativeness and Critical Thinking Devices of Language Supplementary Materials for Primary School
Authors: Rohmani Nur Indah  , Galuh Nur Rohmah
Published: November 2020

Studies show that teaching materials can be integrated with critical thinking skills for enhancing successful learning. However, the integration is not always clear as the communicativeness aspect of the materials also contributes to the goal of effective learning. This study focuses on critical thinking devices and the aspect of communicativeness fulfilled or violated in Indonesian primary school supplementary materials for language courses. It employs content or document analysis on the supplementary materials of the first graders on courses of English, Indonesian and Javanese languages. The analysis is based on the assumption that critical thinking tools and communicative aspects are the two main pillars that characterize the quality of language teaching materials in elementary schools. In addition, critical thinking tools are linked with communicative aspects of language teaching materials to target targeted competency standards. The results show that the communicativeness aspect is supported by the use of real context and authenticity of the materials. In terms of critical thinking device, the supplementary materials are supported by clear purpose in presenting key information. The evaluation on the supplementary materials concerns with the effort to improve the quality of primary school student’s cognitive attainment and critical thinking through communicative supplementary materials.

The obejctives of this research is two-fold: to describe how Indonesian language interferes the recount text written by students of SMA Negeri 1 Toma and to identify the types of Indonesian interferences in recount texts written by Students in question. The design of this research is qualitative. Data of the research were analysed using the qualitative data analysis technique of Miles et al. (2014). The data in this research were recount text written by students of SMA Negeri 1 Toma and semistructure interview taken from the students in SMA Negeri 1 Toma. Results show Indonesian language system interfered the recount texts written by students of SMA Negeri 1 Toma in that the students adopted the way of Indonesian words, phrases, and sentences are structured. The types of Indonesian interference occur in recount text written by students of SMA Negeri 1 Toma distinguished into morphological, syntactical and semantic. Therefore, it can be concluded that students adopted the way of Indonesian words, phrases, and sentences are structured because they do not master Indonesian or L2 and English or L3 most in structuring the phrases and sentences. The teaching of English to non-English speaking people should take into account the highlights of the differences between English and Indonesian linguistic system.

Authors: GÜMÜŞER Tülay
Published: November 2020

Printed textile design is an integral process to decorate both our clothing and design objects. Printed textiles have been displaced by modern production techniques such as transfer print in their historical process starting with traditional production techniques like tie dye, block printing and natural dying. This progress enabled forming detailed patterns and using limitless colors on the surface design of textiles. With the new communication media that arose with technology and artistic manner of expression, typography makes possible different expressions in terms of content and aesthetics on textile surface. How the craft-based design feeds typography and the new dimensions that it has brought to textile design have been researched in this article. How and in which way crafts, arts and design togetherness turn into practice has been examined over design objects composed using traditional production techniques such as quilt technique and modern production techniques such as sublimation printing and digital drawing.

Is Tourism a Key Factor for Economic Growth? Fresh Evidence from South Europe Using Panel Cointegration and PVAR Analyses
Authors: Kostakis Ioannis
Published: November 2020

This paper brings fresh empirical evidence on the relationship between tourism and economic growth for five South European countries over the period 2000Q1-2018Q4 within a multivariate framework. PVAR and panel cointegration analyses are employed to infer the causal relationship between tourism and economic growth. Heterogeneous panel cointegration test reveals a long-run relationship between real GDP, labour force, gross fixed capital formation and tourism. Granger causality validates the bidirectional and unidirectional causal relationship between tourism, labour and economic growth and physical capital and economic growth, respectively. Simultaneously, impulse-response functions of PVAR model highlight the fact that short-run innovations might have a smaller impact on economic growth against a permanent long-run augmentation of these variables. Our findings might leave ample room for government policies to stimulate strategies for higher economic growth.
A (I)MATERIALIDADE DO LIMITE E DA FRONTEIRA
Authors: Silva Leonardo Luiz Silveira da , Silva Juarez Augusto Silveira da
Published: November 2020

Assim como diversos conceitos geográficos, os limites e fronteiras possuem significados que perpassam pelos domínios da materialidade e da imaterialidade. Os tradicionais significados associados a um ordenamento jurídico contrastam com os significados intersubjetivos, que são, por sua vez, construídos pela experiência humana. A concepção de Augustin Berque acerca dos geogramas nos ajuda a ordenar este imbróglio teórico, permitindo-nos sugerir uma justa medida na abordagem dos limites e fronteiras. Deste modo, é o objetivo deste artigo abordar o significado dos limites e fronteiras de forma a mediar a materialidade e a imaterialidade que estão, por sua vez, dialeticamente envolvidas.

CIDADE E CAMPO: CONTINUUM OU DESCONTINUIDADE
Authors: Medeiros Rosa Maria Vieira
Published: November 2020

Esta palestra procura trazer diferentes posições frente às relações do campo com a cidade. De um lado há os que afirmam ocorrer uma fusão entre a cidade e o campo tanto técnica quanto demográfica, funcional e por vezes ideológicas; de outro lado, há aqueles que percebem o espaço rural transformado pela crescente influência da cidade, representada pela modernização, restando ao rural a condição de atraso, de deficiente. No entanto, um olhar mais aguçado mostra o campo com suas singularidades, sua resistência, seu sentimento de pertencimento, suas novas relações, seus novos usos, suas desigualdades, suas tensões, suas carências, sua importância enquanto espaço produtor de alimentos e por fim sua paisagem. É uma nova relação cidade-campo que se constrói gradativamente, são os novos moradores, os turistas e a agricultura desenvolvida de diferentes formas, mas, sobretudo a resistência da cultura do campo.

Published: November 2020

Neste trabalho, apresentamos um conjunto de atividades de leitura, desenvolvidas com estudantes da 3ª série do Ensino Médio de uma escola da rede pública de ensino, por meio da qual procuramos desenvolver as habilidades de leitura e interpretação. Desta forma, utilizamos textos de caráter informativo que trouxeram assuntos e curiosidades relacionados aos conteúdos de Química Orgânica. Para a realização dessas atividades de leitura, pensamos em uma abordagem que estivesse inserida no cotidiano dos estudantes e que estimulasse suas autonomias perante o processo de aprendizagem. Assim, as atividades foram disponibilizadas aos estudantes em um site administrado pelos autores. Os resultados apontam que os discentes apresentam baixa proficiência em leitura e interpretação. Contudo, tais dificuldades parecem poder ser superadas com a inserção de atividades sistemáticas e periódicas de leitura relacionadas a assuntos relevantes à formação dos alunos.
Bordaduras na experiência formativa de mulheres camponesas
Authors: Boleão Jossier Sales , Martins Alice Fátima
Published: November 2020

O texto aborda a experiência desenvolvida com camponesas em oficinas de arpilleras, que se configura em processos de transformação da forma como estas mulheres enxergam suas realidades e se conectam com a realidade de outras, em comunidades rurais distantes e até mesmo desconhecidas. O recorte feito por meio do bordado livre, abriga uma perspectiva estética e política de exercício da solidariedade provocando o deslocamento de vozes hegemônicas e lugares naturalizados como canônicos. A reflexão feita coloca em evidência as possibilidades de diálogos que se tecem em objetos artísticos e para além deles, que emergem do individual ao coletivo e se costuram do coletivo para ressignificar o individual, em total relação com o cotidiano.

Epidemiological characteristics and survival outcomes of children with medulloblastoma treated at the National Cancer Institute (INCA) in Rio de Janeiro, Brazil
Authors: Oigman Gabriela , Osorio Diana , Ferman Sima , Stanek Joseph , Aversa Antonio , Christiani Marcio , Magalhaes Denise , Finlay Jonathan L. , Vianna Denizar
Published: November 2020

BACKGROUND: Medulloblastoma (MB), the most malignant brain tumor of
childhood has survival outcomes exceeding 80% for standard risk and
60% for high risk patients in high-income countries (HIC). These
results have not been replicated in low-to-middle income countries
(LMIC), where 80% of children with cancer live. METHODS: Retrospective
review of 114 children (3-18 years) diagnosed with MB from 1997 to 2016
at INCA. Data on patients, disease characteristics and treatment
information were retrieved from the charts and summarized descriptively.
Overall survival (OS) and event-free survival (EFS) were calculated
using the Kaplan-Meier Method. RESULTS: The male/female ratio was 1.32
and the median age at diagnosis was 8.2 years. Headache (83%) and
nausea/vomiting (78%) were the most common presenting symptoms. Overall
survival (5y) was 59,1% and EFS (5y) was 58,4%. The OS for
standard-risk patients was 69% and 53% for high-risk patients.
Forty-five patients (35%) had metastatic disease at admission. Lower
maternal education correlated with lower OS (71.3% versus 49% p=0.25).
Patients who lived >40km from INCA fared better (OS= 68.2%
versus 51.1% p=0.032). Almost 20% of families lived below the
Brazilian minimum wage. CONCLUSIONS: The epidemiological characteristics
of this series possibly explain the differences in survival that
medulloblastoma patients have in Brazil. Issues related to limited
health care resources, poverty, delayed diagnosis, treatment
abandonment, and malnutrition are reflected in inferior survival
outcomes when compared to high-income countries. Despite the
difficulties encountered in an upper-middle income country, it was
possible to deliver treatment with good results.

In this work, the natural convection in the air gap of an inclined solar
collector contains partitions attached to its glazing has been studied
numerically. The temperatures of the two horizontal walls are constants
and different. The two vertical walls are supposed adiabatic. The
equations of the problem are solved with the finite volume method, using
of the Fluent software. The necessary objective is to study the
influence of the partitions (length and number) on the natural
convection in the air gap of the solar collector. The obtained results
indicate that the presence of the partitions has important influence on
the heat transfer with the decreasing of heat losses with natural
convection, so improving of the solar collector efficiency. In this
study, it reached that the number of partitions must be higher than 10,
and their optimal length is Lp=0.4. The presence of the partitions with
the optimal values reduces the heat losses by natural convection with 46
%.

Objectives: To determine clinical and laboratory features of pregnant
woman with COVID-19 who require respiratory support. To recommend a
management strategy that optimises maternal and fetal outcomes. Design:
An observational cohort study of 7000 maternities between 1st March and
1st July 2020. Setting: Five maternity centres across a maternal
medicine network in north-central London, UK Population: 69 pregnant
women with confirmed acute SARS-COV2 Methods: Review of electronic
healthcare records Main Outcome Measures: Clinical and laboratory
features, maternal and fetal outcomes. Results: Respiratory support was
needed by 15/69 . This cohort was more likely to present with dyspnoea
(10/15 vs 10/54, p<0.001), a lower lymphocyte count (0.90.1
vs 1.40.1 x 109 cells/L; p<0.01) and hypokalaemia (3.80.1 vs
4.00.1 mmol/l, p<0.05). Radiological evidence of lung
consolidation did not identify women in need of respiratory support.
Women on respiratory support underwent childbirth at an earlier
gestation than those who did not (36+4 vs 39+5 weeks,
p<0.001), and required emergency c-section (6/15 vs 8/54,
p<0.05). Childbirth did not improve respiratory function in
those with severe disease, with 3 women remaining on invasive
ventilation despite childbirth. Conclusions: Routine clinical data can
identify pregnant women at risk of severe COVID-19. Pregnant women
should be offered the same treatment as non-pregnant patients but
iatrogenic childbirth should not be the default for women with severe
disease. We propose a management pathway for pregnant women with severe
COVID-19.

Mechanical stretch modulates the proliferation of vascular smooth muscle cells (VSMCs) and plays an important role in the pathogenesis of hypertension, but the underlying mechanisms are unclear. We investigated the role of microRNA- 1-3p (miRNA-1-3p) on the proliferation of VSMCs induced by mechanical cyclic stretch. Our data show that miRNA-1-3p is downregulated in the aorta of the spontaneous hypertension rat (SHR). Pathological mechanical stretch at 15% suppressed the expression of miRNA-1-3p, calponin and SM22, but enhanced the proliferation of VSMCs as well as the expression of the V-ets erythroblastosis virus E26 oncogene homolog 1 (ETS-1), collagen type I alpha (Col-1a), collagen type III alpha (Col-3a) and elastin. Overexpression of miRNA-1-3p inhibited cell proliferation and induced the expression of calponin and SM22, but decreased the expression of ETS-1, Col-1a, Col-3a and elastin. Mechanical stretch at 15% combined with losartan treatment increased the expression of miRNA-1-3p, calponin and SM22, and decreased the expression of ETS-1, Col-1a and Col-3a. Dual luciferase reporter assays revealed ETS-1 as a direct target of miRNA-1-3p. These findings suggest that miRNA-1-3p regulates VSMC function through ETS-1 regulation during hypertension-induced vascular remodeling. MiRNA-1-3p may be a viable therapeutic target for hypertension.

Objectives

To assess factors that may be associated with buccal bone changes adjacent to maxillary first molars after rapid maxillary expansion (RME) and fixed appliance therapy.

Materials and Methods

Pretreatment (T1) and posttreatment (T2) cone-beam computed tomography scans were obtained from 45 patients treated with RME and preadjusted edgewise appliances. Buccal alveolar bone thickness was measured adjacent to the mesiobuccal root of the maxillary first molar 4 mm, 6 mm, and 8 mm apical to the cementoenamel junction, and anatomic defects were recorded. Paired and unpaired t-tests were used to compare alveolar bone thickness at T1 and T2 and to determine whether teeth with posttreatment anatomic defects had thinner initial bone. Correlation analyses were used to examine relationships between buccal alveolar bone thickness changes and amount of expansion, initial bone thickness, age at T1, postexpansion retention time, and treatment time.

Results

There was a statistically significant reduction in buccal alveolar bone thickness from T1 to T2. Approximately half (47.7%) of the teeth developed anatomic defects from T1 to T2. These teeth had significantly thinner buccal bone at T1. Reduction in alveolar bone thickness was correlated with only one tested variable: initial bone thickness.

Conclusions

RME and fixed-appliance therapy can be associated with significant reduction in buccal alveolar bone thickness and an increase in anatomic defects adjacent to the expander anchor teeth. Anchor teeth with greater initial buccal bone thickness have less reduction in buccal bone thickness and are less likely to develop posttreatment anatomic defects of buccal bone.

In this study, the flow characteristics of torpedo-like geometry placed near the free-surface at various angles of attack were investigated numerically. The study was carried out at the Reynolds number of Re=4x104 between immersion ratios of 0.75≤h/D≤3.5 and angles of attack α=0°,4°, 8°, and 12°. Large Eddy Simulation (LES) turbulence model was used along with the Volume of Fluid (VOF) multiphase model to investigate the effects of free-surface. Wake region had an asymmetrical structure near the free-surface as a result of the interaction. A jet-like flow region was observed between the geometry and the free-surface at lower immersion ratios due to the restriction of the flow area. This flow region had a downward movement towards the lower pressure wake region. The drag coefficient, CD, values were increased with the decrease of immersion ratio. At angles of attack α=8° and 12°, the flow separation occurring near the nose caused an additional restriction in the flow area and directed the jet-like flow toward free-surface. Variation of Froude numbers (Fr) depending on the immersion ratio is examined, and it is found that Fr number and corresponding drag coefficient have higher values for the lower immersion ratio. The free-surface effect was found negligible at h/D≥2.5 for all cases.

BTEX (Benzene, Toluene, Ethylbenzene, Xylene) is widely reside in fuel and painting process, such as industrial metal painting. Due to their volatile character, it is easily emitted and recalcitrant in disintegration through aromatic property. These vapor inhaled and slow corruption the lipid membrane of the lungs tissue. Benzene and derivatives are thus more mutagenic and carcinogenic evaluated. The leakage of oil and spoil the soil and groundwater which arouse publi c concern about health respect. Therefore, it is crucial to develop high - efficiency of pollutant transformation, with aims to instant treatment of their toxicity or start remediation process. This study had screened several active isolates from bio - fixed b iofilms consortia were carried. The investigation concerns the supplement of electronic molecules for the remediation effect of BTEX were tried and the cultivation status of facultative anaerobic state were addressed. In highlight of finding with high acti vity consortium was enriched from humic acid eluted from compost of kitchen waste, add additional 400 mg/L BTEX compound over almost one year. Active isolate were compared by using different carbon source as electron donors with 31.2 μM substrate concentra tion. After the basal carbon source as humic acid and molasses was extra added and compared, remedial activity of the strain with 3 - 3> 3 - 1> 2 - 6 were compared. As a second level analysis, the remedial effects shown: methanol>glucose>indole acetic acid>indol e, indicated that the electromotive force might influenced by the grafting carbon chain, the length of carbon grafting, the influence of reducer as ferrous ions in medium, also the free benzoic compound interacted, dynamic directing the direction of electr on flux from humic acid or molasses, overall, humic acid, generally less conversion, believed only support electron mediation in other reaction. While molasses, macromolecular and exhibits a reducing power with glucose and methanol. However, it causes inva lid electronic flux into aromatic conversion but competitively switch to oxidative respiration. Resulted an invalid co - metabolism. The significant of remedial effect by grafting aromatics and soluble humic acid were demonstrated in this report.
