Authors: Grigoryan Olga R. , Krasnovskaya Natalia S. , Mikheev Robert K. , Andreeva Elena N. , Dedov Ivan I.
Published: September 2018

Background: Premature aging are frequently observed among individuals with type 1 diabetes. Decrease of ovarian reserve may be one of the characteristics of such process.
Aims: To evaluate the ovarian reserve function in female patients of reproductive age with type 1 diabetes in comparison with healthy women.
Materials and methods: This study evaluated 224 Caucasian women, age 1837 years with type 1 diabetes and 230 healthy women of comparable age. Serum concentrations of anti-Mullerian hormone (AMH), inhibin B, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone and testosterone were compared on the 23 day of menstrual cycle as ovarian volume and antral follicle count (AFC). In addition, glycated hemoglobin level (HbA1c%) was evaluated.
Results: We reveal statistically significant difference in following parameters in diabetic women in comparison with healthy women: AMH, AFC. But even in diabetic patients parameters remained within reference ranges. There was a pronounced negative relationship between the levels of HbA1c% and AMG.
Conclusions: Ovarian reserve function parameters decrease in young women with type 1 diabetes in comparison with healthy women, but ovarian reserve parameters are in normal reference range. These findings are important in pregnancy planning consulting by gynecologists and endocrinologists. We must recommend to women with type 1 diabetes more early planning of natural pregnancy for treatment with reproductive technology in cases of prolog absence of nature pregnancy.

Published: September 2018

Various researchers in Digital Image processing have developed keen interest in the automation of object detection, description and extraction process used for various applications and this has led to the development of series of Feature detection and extraction models one of which is the Maximally Stable Extremal Regions Feature Algorithm (MSER).  This paper investigates the robustness of MSER algorithm (a blob-like and affine-invariant feature detector) for the detection and extraction of corresponding features used for the automatic registration of series of overlapping images. The robustness investigation was carried out in three different registration campaigns using overlapping images extracted from google earth and image pair acquired from an Unmanned Aerial Vehicle (UAV). Sum of Square Difference (SSD) and Bilinear interpolation models were used to establish the similarity measure between the images to be registered, resampling of the pixel-values and computation of non-integer coordinates respectively while Random Sampling Consensus (RANSAC) algorithm was used to exclude the outliers and to compute the transformation matrix using affine transformation function. The results obtained from this preliminary investigation shows that the processing speed of MSER is quite high for Automatic Image Registration with a relatively high accuracy. While an accuracy of 61.54% was obtained from the first campaign with a processing time of 11.92 seconds, the second campaign gave an accuracy of 52.02% with a processing time of 11.20 seconds and the third campaign produced an accuracy of 55.62% with a processing time of 3.27 seconds. The obtained speed and accuracy shows that MSER is a very robust model and as such, can be deployed as the feature detection and extraction model in the development of an automatic image registration scheme.
A minoritized language on both sides of the border: legal framework and language policy of Catalan in Andorra and Catalonia
Authors: Jiménez-Salcedo Juan
Published: September 2018

This article analyzes the legislation of the two territories that have the most advanced legal framework regarding language policies towards Catalan: Andorra and Catalonia. The study of the legislation in relation to contexts of social and institutional use shows how this legal framework is not sufficient to change Catalan from being a minoritized language, since the phenomenon of minoritization is innate to the ecosystem in which languages develop. This ecosystem is conditioned by the presence of Castilian as a lingua franca on both sides of the border between Andorra and Catalonia. In the case of Andorra, its status as a cross-border microstate makes it a plurilingual space with Castilian as a socially cross-cutting language; moreover, the fact that until recently there was no network of state schools hindered Catalan language normalisation efforts. Catalonia, on the other hand, is an even more complex example on account of how the implementation of llengua pròpia policy contradicts the constitutional control the Spanish state exercises on this.

Authors: Wang Jianyong , Zeng Ying , Liang Zufeng , Xu Yani , Zhang Yuanxiang
Published: September 2018

In this work, we are concerned with the ion acoustic quasi-soliton in an electron-positron-ion plasma with superthermal electrons and positrons. By using the reductive perturbation method, the Korteweg-de Vries equation is derived from the governing equations of ion acoustic waves. An interesting soliton-cnoidal wave solution of the Korteweg-de Vries equation and its quasi-soliton behaviour are presented. The influence of electron superthermality, positron superthermality and positron concentration ratio on characteristics of the quasi-soliton is confirmed to be significant.
GABAergic modulation of serotonergic neurons in the dorsal raphe nucleus
Authors: Hernández-Vázquez Fabiola , Garduño Julieta , Hernández-López Salvador
Published: September 2018

The dorsal raphe nucleus (DRN), located in the brainstem, is involved in several functions such as sleep, temperature regulation, stress responses, and anxiety behaviors. This nucleus contains the largest population of serotonin expressing neurons in the brain. Serotonergic DRN neurons receive tonic γ-aminobutyric acid (GABA)inhibitory inputs from several brain areas, as well as from interneurons within the same nucleus. Serotonergic and GABAergic neurons in the DRN can be distinguished by their size, location, pharmacological responses, and electrophysiological properties. GABAergic neurons regulate the excitability of DRN serotonergic neurons and the serotonin release in different brain areas. Also, it has been shown that GABAergic neurons can synchronize the activity of serotonergic neurons across functions such as sleep or alertness. Moreover, dysregulation of GABA signaling in the DRN has been linked to psychiatric disorders such as anxiety and depression. This review focuses on GABAergic transmission in the DRN. The interaction between GABAergic and serotonergic neurons is discussed considering some physiological implications. Also, the main electrophysiological and morphological characteristics of serotonergic and GABAergic neurons are described.
Development of hydroxyapatite-polylactic acid composite bone fixation plate
Authors: Leksakul Komgrit , Phuendee Mintra
Published: September 2018

Bone damage patients may suffer from metal toxicity resulting from an adverse reaction. To avoid the need for a second operation, we set out to identify a material that can be used as a substitute for metal in small fragment plates, which is compatible with the human body. Thus, in this study, we set out to study the development of a material that can be applied to the small fragment plate, based on a hydroxyapatite (HA)-polylactic acid (PLA) composite. This study examined three main factors, namely, the ratio of the PLA to the HA, injection temperature (T) and injection pressure (P). Based on the ASTM standard, the best results (Code 4 and Code 1) obtained from the mechanical property tests (tension and flexural) were 44.02 MPa and 63.97 MPa, respectively. When compared to HA-HDPE, our material offers both strength and biodegradable/biocompatible advantages. By inspection with scanning electron microscope (SEM) and energy-dispersive spectrometry (EDS), we could identify the components of the HA and distribution pattern. In terms of biocompatibility, Code 1 is promising. To maximize the composite desirability, optimal condition was mathematically calculated. In addition, finite element analysis confirmed that the proposed bone fixation plate would not be damaged when the wrist is impacted.

Authors: Kunze Ekkehard , Lilla Nadine , Stetter Christian , Ernestus Ralf-Ingo , Westermaier Thomas
Published: September 2018

Background

To analyze whether magnesium has a neuroprotective effect during episodes that indicate a critical brain perfusion after aneurysmal subarachnoid hemorrhage (SAH).

Methods

107 patients with aSAH were randomized to continuously receive intravenous magnesium sulfate with target serum levels of 2.0 – 2.5 mmol/l (n = 54) or isotonic saline (n = 53). Neurological examination and transcranial Doppler sonography (TCD) were performed daily, Perfusion-CT (PCT) was acquired in 3-day intervals, angiography in case of suspected vasospasm. The primary endpoint was the development of secondary infarction following episodes of delayed ischemic neurological deficit (DIND), elevated mean flow velocity (MFV) in TCD or pathological findings in PCT.

Results

In the magnesium group, 9 episodes of DIND were registered, none was followed by secondary infarction. In the control group, 23 episodes of DIND were registered, 9 were followed by secondary infarction (p < 0.05). In the magnesium group, 114 TCD-measurements showed an elevated MFV(> 140 cm/s). 7 were followed by new infarction. In control patients, 135 measurements showed elevated MFV, 32 were followed by new infarction (p < 0.05). 10 of 117 abnormal PCT-findings were followed by new infarction, compared to 30 of 122 in the control-group (p < 0.05).

Conclusion

DIND, elevated MFV in TCD and abnormal PCT are findings which are associated with an increased risk to develop delayed secondary infarction. The results of this analysis suggest that magnesium-treatment may reduce the risk to develop infarction in a state of critical brain perfusion.

Published: September 2018

Objectives

Shift workers are at an increased risk of diet-related chronic conditions. We aimed to investigate dietary intake and dinner timing among shift workers.

Methods

A questionnaire survey was administered to the employees of 43 companies in Japan between December 2013 and February 2014. The dietary intake of workers was assessed through a validated food frequency questionnaire (FFQ) . Nutrient intake was evaluated by adjusting the total energy intake using a nutrient residual model. Analysis of covariance was used to obtain the means of total energy and nutrient intake by the work schedule (shift or daytime), and the means of total energy and nutrient intake by dinner timing (regular or irregular) .

Results

Valid responses were obtained from 2,062 daytime and 302 shift workers. A valid response rate to the FFQ was slightly but significantly lower among shift workers than among daytime workers (87.1% and 91.8 %). When compared to daytime workers, shift workers were more likely to eat dinner at irregular times (46.7% vs. 3.6%). Shift work was associated with a higher mean body mass index (23.4 kg/m2 vs. 22.3 kg/m2), a higher proportion of being overweight (27.7% and 18.8%), higher total energy intake, and lower intakes of dietary fiber, vitamin B2, folic acid, vitamin C, potassium, calcium, magnesium and iron. Moreover, irregular dinner timing was associated with lower intakes of protein, folic acid, and zinc in daytime workers, and lower intakes of carbohydrate and copper in shift workers.

Conclusions

These findings indicate a need to improve the diet of shift workers.
Alfa-radiolysis of methane with radon-222 and radon-220 (thoron) v1
Authors: Schimmelmann Arndt , Fernandez-Cortes Angel , Cuezva Soledad , Streil Thomas , T. Lennon Jay
Published: September 2018

Atmospheric methane is rapidly lost when it enters humid subterranean critical and vadose zones (e.g., air in soils and caves). Because methane is a source of carbon and energy, it can be consumed by methanotrophic methane-oxidizing bacteria. As an additional subterranean sink, it has been hypothesized that methane is oxidized by natural radioactivity-induced radiolysis that produces energetic ions and radicals, which then trigger abiotic oxidation and consumption of methane within a few hours. Using controlled laboratory experiments, we tested whether radiolysis could rapidly oxidize methane in sealed air with different relative humidities while being exposed to elevated levels of radiation (more than 535 kBq m-3) from radon isotopes 222Rn and 220Rn (i.e., thoron). We found no evidence that radiolysis contributed to methane oxidation. In contrast, experiments with moist soils in the same apparatus without added radon isotopes confirmed biodegradation of methane by methane-oxidizing bacteria.

Authors: Ferreira Ana Filipa , Silva Catarina Miranda , Antunes Dora , Sousa Filipa , Lobo António Carlos , Moura Paulo
Published: September 2018

Introdução: Não existe consenso internacional quanto aos critérios de diagnóstico da diabetes gestacional. Em Portugal, os critérios de Carpenter e Coustan foram substituídos por uma adaptação dos critérios da International Association of Diabetes and Pregnancy Study Groups. O objetivo deste estudo foi comparar a incidência e outcomes obstétricos/perinatais das grávidas com diabetes gestacional segundo os critérios atuais e prévios.Material e Métodos: Estudo retrospetivo de 1218 gestações únicas complicadas com diabetes gestacional cuja vigilância/parto ocorreu entre 2008-2015. Consideraram-se dois grupos: diagnóstico pelos critérios da Direção Geral da Saúde – International Association of Diabetes and Pregnancy Study Groups (grupo 1); diagnóstico segundo Carpenter e Coustan (grupo 2), tendo sido feita análise estatística comparativa.Resultados: A incidência da diabetes gestacional duplicou (9,4% vs 4,6%) e o número de consultas/ano aumentou consideravelmente (~ 3 000 vs ~ 2 000). No grupo 1 verificou-se um risco inferior de recém-nascidos macrossómicos em relação ao grupo 2 [RR 0,44 (IC (95%): 0,26 – 0,76)], e um risco mais elevado de recém-nascidos leves para a idade gestacional (LIG) [RR 1,99 (IC (95%):1,19 – 3,31)]; um risco cerca de seis e quatro vezes superior de hipoglicémia [RR 6,30 (IC (95%): 3,39 – 11,71)] e hiperbilirrubinémia [RR 3,89 (IC (95%): 2,25 – 6,72)] neonatais, respetivamente. Não houve diferenças em relação a outros outcomes.Discussão: A redução dos recém-nascidos macrossómicos não resultou em melhoria dos outcomes, havendo um aumento dos recém-nascidos leves para a idade gestacional bem como de complicações neonatais. Os critérios atuais poderão associar-se a maiores gastos em saúde, devido ao aumento considerável da incidência de diabetes gestacional e maior vigilância em consultas, sem benefícios obstétricos/perinatais.Conclusão: A aplicação dos critérios da Direção Geral da Saúde – International Association of Diabetes and Pregnancy Study Groups associou-se a redução da macrossomia, não acompanhada de uma melhoria dos outcomes. É discutível o benefício destes critérios em relação aos anteriormente preconizados.

Background: Breast cancer (BC) is the leading cause of death cancer in women. Cancer therapies using TNFα and IFNγ have been recently developed by direct effects and activation of immune responses. This study was performed to evaluate the effects of TNFα and IFNγ directly, and TNFα and IFNγ secreted by Conditioned Medium-human Wharton’s Jelly Mesenchymal Stem Cells (CM-hWJMSCs) toward apoptosis of BC cells (MCF7).Materials and Methods: BC cells were induced by TNFα and IFNγ in 175 and 350ng/mL, respectively. CM-hWJMSCs were produced by co-culture hWJMSCs and NK cells that secreted TNFα, IFNγ, perforin (Prf1), granzyme B (GzmB) for treating BC cells. The BC cells were treated with CM-hWJMSCs in 50%. The expression of apoptotic genes Bax, p53, and the antiapoptotic gene Bcl-2 were determined using RT-PCR.Results: TNFα and IFNγ at concentration of 350 ng/mL induced higher Bax expression compared to 175 ng/mL. TNFα and IFNγ 350 ng/mL, 175 ng/mL induced p53 expression, whilst TNFα and IFNγ at 350 ng/mL decreased Bcl-2 expression. Perf1, GzmB, TNFα and IFNγ-containing CM-hWJMSCs induced significantly apoptosis percentage, induced Bax expression, but did not effect p53, Bcl-2 expression.Conclusion: TNFα and IFNγ directly induce Bax, p53, decrease Bcl-2 gene expression. The Prf1, GzmB, TNFα, IFNγ-containing CM-hWJMSCs induce apoptosis and Bax expression.Keywords: breast cancer, Wharton’s Jelly mesenchymal stem cells, TNFα, IFNγ

Family Solanaceae: Taxonomy and modern trends
Authors: Ganaie Masood Majaz , Reshi Zaffar Ahmad , Verma Vijeshwer , Raja Vaseem
Published: September 2018

Solanaceae belongs to that group of families, which are included in almost all angiosperm classifications indicating naturalness of the family. The family being one of the most evolutionarily successful and advanced taxa shows astonishing level of diversity reflected in the form of various types of adaptations. The high level of diversity within the family in addition to other unusual features have reflected in poor understanding of its phylogenetics. Fossil record of angiosperms particularly of Solanaceae) is very meager and relatively recent, so use of morphology and other conventional characters is not convincing in revealing true phylogeny of the family. This all has necessitated using alternative marker types in phylogenetic analysis of the family. Since advent of molecular biology molecular markers have been constantly refined to serve the purpose. Solanaceous species, such as tomato, potato, chilli pepper, tobacco, and petunia serve as model systems for the investigation of molecular and agronomic questions, and the family is the subject of intensive phylogenetic studies that are providing new insights into species boundaries and generic relationships. Results from recent morphological, molecular, and biosystematic research have shed new light on the systematic relationships in the family at virtually all taxonomic levels from subfamily to variety.
A comparative study on elemental composition in some wild and cultivated medicinal plants
Authors: B. Kamatchi Kala , R. Vigneswari
Published: September 2018

An evaluation of elemental composition in medicinal plant is important because mineral contents may be the source of a pharmacological effect. Four elements (Na, K, Mg and Zn) were analysed in wild and cultivated medicinal plants such as Andrographis paniculata, Vitex negundo and Solanum surattense. The present study revealed the presence of minerals such as Na, K, Mg and Zn in all the studied medicinal plants grown in both wild and domestic condition. The presence of those elements indicates the medicinal value of the studied plants. The results show that the cultivated medicinal plants contain more concentration of all the four investigated elements when compared to medicinal plants collected from wild area.

#DigPed Narratives in Education: Critical Perspectives on Power and Pedagogy
Authors: Koseoglu Suzan , BOZKURT Aras
Published: September 2018

This mixed methods study addresses a knowledge gap in the nature and effects of networked scholarship. We analyze #DigPed, a Twitter hashtag on critical pedagogy, through the lens of Tufekci’s Capacities and Signals framework in order to understand (1) how educational narratives develop and spread on #DigPed, and (2) the nature of their capacities. Using Social Network Analysis and thematic analysis of content, we identify three prominent narratives in the network and discuss the network structures from a critical perspective. Based on the findings, we propose pedagogic capacity—the power to initiate a productive and potentially transformative educational discourse, within one’s self and within communities—as an additional lens to explore the spread and impact of critical narratives in education. Findings confirm the view that networked spaces are organized by hidden hierarchies marked by influence.

Seren taun is a traditional ceremony performed by Kasepuhan Cisungsang, Banten Kidul, as a vehicle to give thanks to God Almighty for their harvest. In the perspective of intracultural communication. Seren taun is an indigenous communication medium that serves to transform the values of adat from one generation to the next for the preservation of their cultural identity. Therefore, every ceremony of ceremonial seren taun must be attended and followed by all members of indigenous communities without exception, either living in custom territory or outside customary territory. Meanwhile, in the perspective of intercultural communication, seren epidemic ceremony becomes a medium for the existence of adat, so that its existence is accepted, acknowledged, and protected by the state.This study focuses on understanding: First, how the kasepuhan community makes seren taun as a medium of communal communication in order to reinforce their cultural identity. Second, how the society kasepuhan make seren epidemic as a medium of communication for the sake of existence. Based on these two questions, it is understood that seren taun has expanded its function. As a form of respect for the earth (land) and thankfulness of the harvest, as well as the symbolic form of existence of society. The existence of expansion of function in seren taun, based on awareness affirming identity as indigenous peoples with all its distinctive style and culture, which is not owned by other society entity, as well as contestation of their cultural identity to other party for the sake of existence of adat.Â Keywords: Seren Taun, Kasepuhan Cisungsang, Cultural Identity, Customary ExistenceÂ

First love simplicity: A systemic-functional perspective study of Karina Del Campo�s Do You Remember Our Love?
Authors: Purwanto Sugeng , Nurhamidah Idha
Published: September 2018

The current study aims at exploring the intended meaning and structure of a poem entitled �Do You Remember Our Love?� written by a poet, ��Karina Del Campo (2009) in both interpretational and systemic functional perspectives. In the former, the poem was examined interpretatively in order to find out the possible stance of the poet; meanwhile the later was an analytical representation of systemic functional grammar in the framework of construing the three domains of meanings: ideational, interpersonal and textual in order to arrive at the field, the tenor and the mode of the discourse.� It turns out that the poem is �a reflection of a woman�s feeling (the poet�s) toward her ex-boyfriend�finely described in a repeated style of the major clause, supported and elaborated in several minor clauses. The poet tries very hard to ignite her ex-boyfriend�s love memories with her and to possibly invite him to reunite even though it seems to be a mission impossible. The poem has both social and psychological impacts on the poet herself and the readers in a wider scope.

Lithic morphological organisation: Gahagan bifaces from the Southern Caddo Area
Authors: Selden Robert Z. , Dockall John E. , Shafer Harry J.
Published: September 2018

This analysis of Gahagan biface morphology enlists the three largest samples of Gahagan bifaces, to include that of the type site (Gahagan Mound) as well as the Mounds Plantation and George C. Davis sites. Results indicate a significant difference in Gahagan biface morphology at the Mounds Plantation site when compared with Gahagan bifaces from the Gahagan Mound and George C. Davis sites. Tests for allometry and asymmetry were not significant. The test of morphological disparity indicates that Gahagan bifaces produced at the Mounds Plantation site occupy a more restricted range of morphospace than those produced at Gahagan Mound, providing evidence for standardisation and diversity in Caddo biface production. While the sample includes a wide range of variability, the test of morphological integration indicates that Gahagan bifaces are significantly integrated, meaning that those traits used to characterise their shape (blade and base) vary in a coordinated manner. These results articulate with a shift in Caddo bottle morphology over the same geography, potentially indicating two previously unrecognised and morphologically-distinct lithic and ceramic production areas.
Application of Some Remote Sensing Techniques to Detect the Mineral Deposits for Region of Bahar An-Najaf by Using Landsat-8 (OLI) Data
Authors: Taki  Hassan Ebtihal
Published: September 2018

Landsat-8 was used for the Operational Land Imager (OLI) for the southwestern part of Najaf province to detect and distinguish the most important mineral compounds of the region using several techniques for processing space images. The image processing methods used in this study includes, color composite   band ratio   in addition to  Principal Component Analysis  (PCA).  Visible, near and short infrared bands have been used to detect iron oxides, iron minerals, and clay minerals, while thermal bands have been used to distinguish silicate minerals. The color composite (RGB) of the bands  (B2B5B7), (B5B7B3) and (B10, B11, B7) have been used to determine region of   iron oxide, clay and iron minerals as well as silicate minerals , respectively. The band ratio of  4/2, 6/5 and 6/7 have been used to detect the presence of iron oxides and iron and clay minerals, respectively. The color composition has been applied on the band ratios (6/7,6/5,4/2)  to obtain a better distinction for mineral deposits in the region. From results of (PCA) and based on signal and values of eigenvectors for PCS bands, PC3 has been selected to represent clay minerals, PC4 for iron minerals and PC5 for iron oxides. The color composite application on (PC3, PC4, PC5) shows more details about the mineral deposits of the region
Cognitive Mechanism of Analogy and its Role in Processes of Primary Metaphor Creation
Authors: Borodiichuk N. V.
Published: September 2018

The article deals with the problem of the cognitive nature of metaphor formed in the medium of mythological consciousness of the primitive human. It is supposed that such the main features of the mythological thinking as sensory concreteness and inability to form abstract notions caused the nature of the primary metaphor which was formed through the cognitive mechanism of analogy the surrounding objects and phenomena, and the inner mental states of the human – this metaphor was not linguistic, but concrete and sensory. It is ascertained that the direction of metaphorization in the primitive consciousness was inverted to modern one, because the modern people mind uses more intelligible concrete concepts to express abstract concepts, but the primitive humans conceiving themselves as a part of the nature and understanding their inner world as the outer one projected their inner states, which are comprehended as abstract now, onto the natural phenomena, which can be perceived through the organs of sense. It is argued that formation of critical abstract thinking is related with the development of the human cognitive abilities, what caused the metaphorization veer and also the transition from the mythological mind to linguistic one. It is analyzed three approaches to solving the problem of the relation between language and myth where an important argument was the metaphoricity both of thinking and language: 1) the linguistic theory of myth by M. Müller according to which the loss initial sense of the linguistic metaphor generated myth; 2) the theory of myth based not on the linguistic metaphor, but on the concrete sensory analogy of the real objects and human perceptions (E. Tylor, A. Potebnya); 3) Neo-Kantian theory by E. Cassirer which postulates the simultaneous development of language and myth which have the common sources. It is proved that metaphoricity is inherent in the human mind of every historical period, because the linguistic metaphor is based on the cognitive one, that is the latter makes it possible to comprehend the world and ourselves in this world and express the obtained knowledge by means of language. At the same time, metaphoricity and abstractness of thinking are harmonious processes which provides the productive cognizing of the world and the creative working its results out through the fixation of them in the linguistic forms.
