ARAP BAHARI SÜRECİNDE ORTADOĞU’DA GÜVENLİK VE DIŞ POLİTİKA: SUUDİ ARABİSTAN ÖRNEĞİ
Authors: ACAR Necmettin
Published: December 2018

Dış politikasını büyük oranda yumuşak güç unsurlarına dayandıran, bölgesel güçlerle askeri karşıtlıklardan kaçınan, çatışan taraflar arasında arabuluculuğa öncelik veren, bölgesel bir güç tarafından tehdide maruz kaldığında tehdidin kaynağını yatıştırmayı tercih eden, rejim güvenliği ve toprak bütünlüğünü ABD’nin güvenlik garantilerine dayandıran S. Arabistan’ın Arap Baharı sürecinde bu geleneksel dış politikasından radikal bir şekilde ayrıldığı gözlemlenmiştir. Irak işgali ve Arap Baharı sürecinin Irak, Suriye ve Mısır gibi güçleri zayıflatması ile oluşan güç boşluğunu doldurmak için iddialı bir dış politika takip eden S. Arabistan bu süreçte Bahreyn ve Yemen’e doğrudan müdahale etmiş, devrimci dalgayı tersine çevirmek için MENA bölgesinde diplomatik ve ekonomik gücünü kullanmış, güvenlik yapılanmasında çeşitliliğe giderek ABD dışındaki ülkelerden silah alımları yapmış, Arap Ordusu ve Arap-İslam NATO’su kurma girişimleriyle bölgesel liderlik rolüne soyunmuştur. S. Arabistan açısından tehdit teşkil eden üç önemli gelişme; kaya gazı devrimi ile bölge kaynaklarına bağımlılıktan kurtulan, güvenlik ve dış politikasının odağını Ortadoğu’dan Pasifik bölgesine kaydıran ABD ile ilişkilerin bozulması, bölgede oluşan güç boşluğunu İran’ın doldurma girişimleri, Katar, Türkiye ve İhvan yönetimindeki Mısır’ın ittifakıyla şekillenecek Sünni eksenin S. Arabistan’ı bölge politikalarından marjinalleştirme ihtimalidir. Fırsatlar ise; Suudi ulusal gücünün nispi olarak artışı ve bu artışa dayanarak bölgedeki güç boşluklarını doldurma imkânlarının oluşmasıdır. S. Arabistan’ı yöneten İbn Suud ailesinin üç temel güvenlik ve dış politika önceliği bulunmaktadır; rejim güvenliği, toprak bütünlüğü ve bölgesel güvenlik. Suudi dış ve güvenlik politikası bu üç temel önceliğe göre biçimlenmektedir. Arap Baharının bölge genelinde yarattığı tehditleri bertaraf etmek, fırsatlardan istifade edebilmek için ülkenin dış ve güvenlik politikası yeniden formüle edilmiştir.

Authors: Simões Yagho de Souza , Santos Carol Ferreira Rezende
Published: December 2018

Esse artigo tem como objetivo comparar duas técnicas de reforço estrutural, fibra de carbono e chapa metálica, utilizadas para recuperação de elementos de concreto armado degradados pela ação do fogo. Simula-se a deterioração de uma viga em situação de incêndio a partir de uma modelagem numérica térmica e, em seguida, são calculados os reforços mencionados. A fibra de carbono exigiu uma menor área em comparação àquela para chapa metálica, em função de sua elevada resistência mecânica. Como limitações, cita-se o fato de o estudo ser preliminar e envolver apenas uma análise térmica da viga, não sendo considerado o carregamento atuante e suas implicações. Conclui-se que a fibra de carbono apresenta maiores vantagens no que diz respeito ao reforço de vigas.

The role of translanguaging in the multilingual turn: Driving philosophical and conceptual renewal in language education
Authors: Prada Josh , Turnbull Blake
Published: December 2018

The multilingual turn refers to a recent series of shifts in the core philosophical underpinnings in traditional foreign and second language classroom practice. These changes promote the normalization of processes and practices characteristic of bi- /multilingual speakers. This, in turn, has stimulated new ways of teaching and learning in the classroom. The goal of this article is twofold: first to chart the central developments that have led to the emergence of the multilingual turn thus far, and second to provide an account of how classroom translanguaging is fundamental to present and future developments. We present the conceptual framework undergirding the multilingual turn, before providing an overview of traditional tenets of foreign and second language education. We then examine translanguaging and its implications for language education, and end with a presentation of strategies that may facilitate the implementation of the multilingual turn in the additional language classroom.
Introduction to the special issue: On the transgressive nature of translanguaging pedagogies
Authors: Prada Josh , Nikula Tarja
Published: December 2018

As translanguaging gains traction in language education, its political and ideological implications are becoming central considerations to researchers and practitioners. In this introductory article to the special issue, “Translingual and Multilingual Pedagogies” for the EuroAmerican Journal of Applied Linguistics and Languages, we provide a conceptual point of departure on the notion of translanguaging by revisiting Li Wei’s (2011) threefold description of its prefix trans- (i.e., transcending, transformative, transdisciplinary), which we expand by adding a new definitional element, transgressive, to reflect our understanding of translanguaging as politically charged and disruptive by virtue. We then move on to provide an overview of the articles and book reviews included in this special issue.
AZINLIK HAKLARI ile YERLİ HALKLARIN HAKLARININ KOLEKTİF HAK KULLANIMI ÇERÇEVESİNDE KARŞILAŞTIRILMASI
Authors: MIZRAK Dilan
Published: December 2018

‘Azınlık’ ve ‘yerli halk’ değişken, henüz net bir hukuki tanıma kavuşmamış kavramlardır. Bununla beraber, her iki grup için kabul gören bakış açısı, bulundukları devlet nüfusunun geri kalanından farklı özelliklere sahip olmalarıdır. Bu farklılık sebebiyle yaşanılabilecek olası insan hakları ihlallerinin önüne geçmek için söz konusu gruplar bakımından insan hakları mekanizmalarınca teminat altına alınan hakların kolektif kullanımı meselesi tartışılmaktadır. Gerek ulusal gerek uluslararası düzeyde yerli halklara ilişkin düzenlemeler azınlıklarla karşılaştırıldığında daha net ve fazladır. Uluslararası ve bölgesel nitelikli insan hakları mekanizmalarına bakıldığında, kimi adımlar atılmış olmasına rağmen azınlık hakları hâlâ kolektiflik niteliğini tam olarak sağlayamamıştır. Uluslararası organlar ve devletlerce; metinlerin azınlık haklarının kolektif kullanımını öngörmediği savunulsa pek çok hukukçu uluslararası metinlerin dinamik yorumlanması gerektiğinden hareketle kolektif hakların kullanımının önünde engel olmadığını savunmaktadırlar. Yerli halkların kolektif hak kullanımıyla ilgili olarak ise, 1980'lerden ve özellikle 90'lardan itibaren izlenen politikada değişiklikler olduğu görülmektedir. Bölgesel olarak yürütülen çalışmalar neticesinde hazırlanan taslak bildiriler olmakla birlikte, konuya ilişkin önemli gelişme Birleşmiş Milletler Yerli Halkların Hakları Bildirisinin kabulüdür.

Published: December 2018

Objectives: Atrial fibrillation is the most frequent cardiac arrhythmia affecting over 3 percent and appears to be increasing in general population. In addition to widely discussed such risk factor as obesity, arterial hypertension, electrolytes disbalances and dysfunction of thyroid, there is more and more evidence of human heath interactions with environment parameters such as humidity, temperature, the lunar and the solar activity. Atrial fibrillation, a disorder of heart conductive system, in several studies have been indicated as affected by local Earth magnetic field changes. The study was aimed to analyse possible correlations between the power in the local Earth time-varying magnetic field and admission due to atrial fibrillation. Methods: Two-hundred-fifty-one patients diagnosed with acute atrial fibrillation and treated in Department of Cardiology of Hospital of Lithuanian University of Health Sciences Kaunas Clinics during year of 2016 were retrospectively included into the study. Weekly prevalence of acute atrial fibrillation was compared with weekly summarised changes in the local Earth magnetic field strength. One-year was divided into two time periods according to week number: the first period included weeks from 1 to 26 and the second period included weeks from 27 to 52. Results: Analyses have shown from weak to moderate significant correlations. Tendencies towards higher power magnetic field in low frequently ranges to be associated with higher admission rates were noticeable throughout all analysed periods. Atrial fibrillation concomitant with arterial hypertension was indicated as combination increasing severity of correlation coefficient. Conclusion: Significant correlations between acute atrial fibrillation and the local Earth time varying magnetic field changes were found. Increased magnetic field in low frequency ranges are associated with episodes of acute atrial fibrillation. Arterial hypertension is significantly associated with higher admission due to atrial fibrillation rate under low frequency local Earth magnetic field range.
Some possibilities of modeling of moving load on concrete pavements
Authors: Valsšková Veronika , Melcer Jozef
Published: December 2018

The submitted paper is devoted to the numerical modeling of the dynamic effects of moving vehicles on concrete pavements. The finite element method, namely the ADINA program, is used to model the problem. To solve the task, it is necessary to create a vehicle and a road computational models. The vehicle model is spacious and corresponds to a heavy truck of the Tatra type. The so-called single-layer road model on an elastic Winkler foundation is used. Concrete pavements are modeled using shell or solid elements. The output of the solution is the time course of the dynamic deflections at the individual points of the slab and internal forces and the stress states in the concrete slab at the individual time points of the solution. The calculation results for each computational model are compared to each other.

Published: December 2018

Traffic seismicity is the current phenomenon, and the impact of traffic seismicity on monumental buildings has significant importance. This paper discusses the results of three different case studies, where the impact of traffic seismicity is important. These buildings were selected as case studies, due to a short distance from the source of the vibrations, respectively the traffic lines. All these three buildings are historically significant in their region. The contribution is focused on experimental results and on numerical analysis of building structures. Works of this and similar character supports to the establish and determinate limit criteria in assessing the dynamic response to the effects of traffic seismicity. For this reason, it is important to realize a great amount of measurements, that such conclusions can be expressed. This requirement is based on insufficient legislation and standards in technical field in Slovakia.
Comparison of approximate assessments of the harmfulness of mining shocks using ground and building foundation vibrations
Authors: Kuzniar Krystyna , Stec Krystyna , Tatara Tadeusz
Published: December 2018

Mining tremors belong to so-called paraseismic sources of vibrations and can be classified as the most intensive of such type sources of surface structures vibrations, hazardous for buildings. According to the soil-structure interaction effect, the ground vibrations are modified during their transmission to foundations of building. In consequence, the differences between the records of vibrations registered on the ground next to a building and at the building foundation (simultaneously), can be significant. The paper is focused on the analysis of the differences in the approximate assessments of the harmfulness of mine-induced rockbursts on the basis of simultaneously occurring free-field vibrations next to the building, or building foundation vibrations. The analysed vibrations were induced by shocks in the Upper Silesian Coalfield (USC), one of the most seismically active area in Poland. Typical administrative, masonry, low-rise actual building was taken into account. The harmfulness of mining-induced vibrations to the building was estimated using appropriately prepared scales for this region. Results corresponding to two versions of the scales were analysed: the new proposition – Mining Seismic Intensity Scale GSIS-2017, as well as its former version – the Mining Intensity Scale GSI-GZWKW-2012. Both of the scales were considered in two versions: velocity version (basic), and acceleration version (auxiliary). It is worth mention that these scales base on the ground vibration parameters. However, for research and comparison purposes, they were applied also for building foundation vibrations.
Ambient vibration measurements of steel truss bridges
Authors: Venglár Michal , Sokol Milan , Ároch Rudolf
Published: December 2018

Dynamic measurements of two steel truss bridges for Structural Health Monitoring (SHM) were performed. The investigated bridges were: a single supported one span truss bridge and a multi-span truss bridge. Two possibilities of measuring setup were considered. A simple arrangement made up of one polygon has been used for data acquisition of the single span truss bridge. A more complex measuring setup made up of two polygons with up to 32 channels has been used for the large bridge with an entire length reaching up to 500 m. A connection of both measuring polygons was achieved by Wi-Fi antennas. The reason why the multi-span truss bridge was chosen for SHM is that the construction is nowadays overloaded. The dynamic measurements were done, ambient and semi-ambient data were analysed. After that, some mode-shapes were identified from the acquired data and then the data were compared with numerical calculations. Finally, experiences and conclusions from the ambient data measurement are summarized.

Authors: Zhou Xuhong , Yang Qingshan , Li Jiang , Ma Xiaoxue
Published: December 2018

Human-induced vibration has become a serious serviceability problem due to the larger opening of girder, lighter floor systems and longer spans designed and used in practice. Vibration tests were undertaken in laboratory to research the vibrational characteristics of the arch pre-stressed concrete truss (APT) system spanning 16.0 m. Results from ambient vibration, impulse excitations (heel-drop and jumping) and steady-state incentives (walking and running) were presented. Dynamic characteristics such as natural frequencies, damping ratios, mode shapes and acceleration responses were studied and checked against the existing codes. Experimental results show that the investigated APT girder possesses high fundamental frequency and low damping ratio. Moreover, the perception factors based on the root-mean-square acceleration, vibration dose value (VDV) and psychological comfort data were obtained. Lastly, the threshold accelerations and VDVs were suggested for evaluating the human-induced vibration.

Authors: Li Leixin , Chen Luyun , Yi Hong
Published: December 2018

The influence of complex pre-stress on the circular thin plate is investigated in this study to solve the non-uniform stress distribution problem. The differential equation of the circular plate with complex pre-stress distribution is derived based on the strain-displacement equation. The analytical method of free vibration for the circular plate with complex pre-stress distribution is proposed, in which the complex pre-stress and displacement function of the circular plate are expanded into the cosine trigonometric series. The influence of the different types of welding residual stress distribution on the natural frequency and the mode shape of the circular plate structure is compared. Finally, the effectiveness of the proposed model is verified through finite element method.
Fault diagnosis of rolling element bearing based on a new noise-resistant time-frequency analysis method
Authors: Wang Hongchao , Hao Fang
Published: December 2018

When fault arises in the rolling element bearing, the time-domain waveform of fault vibration signal will take on the characteristic of cyclostationarity, and the spectral correlation (SC) or spectral correlation density (SCD) basing on second order cyclic statistic is an effective cyclostationarity signal processing method. However, when the fault signal is surrounded by strong background noise, the traditional signal processing methods such envelope demodulation analysis and SC would not work effectively. The paper improves the SC method and a new time-frequency analysis method naming improved spectral correlation (ISC) is proposed. The proposed method is much more noise-resistant than SC through the verification of simulation analysis results. Besides, it takes on modulation phenomenon usually when fault arises in the rolling element bearing and the aim of fault feature extraction is to extract the fault characteristic frequency only or cyclic modulation frequency and the modulated frequency or carrier frequency buried in the object vibration signal is neglected. So, the paper improves the ISC further and the improved ISC (IISC) is proposed. The IISC will extract the modulation frequency only and it has the advantages of much clearer expression effect and better extraction effect. The effectiveness and feasibility of the proposed method are verified through the three kinds of fault (inner race fault, outer race fault and rolling element fault) of rolling element bearing. Besides, the advantages of the proposed method over the other relative time-frequency analysis methods such as ensemble empirical mode decomposition (EEMD) and spectral kurtosis (SK) are also presented in the paper.

Authors: Ma Fangwu , Wang Jiawei , Wang Yang , Yang Longfan
Published: December 2018

Owing to significant influences of in-wheel motors on the performance of suspension, a modified GPSO-LQG controller is proposed for one-quarter vehicle suspension with the purpose of optimizing suspension performance for entire speed ranges. After the introduction of one-quarter vehicle suspension model, road surface excitation model and magneto-rheological damper model, the GPSO-LQG controller is investigated with three weighted coefficients optimized by utilizing the Genetic Particle Swarm Optimization (GPSO). With the intension of meeting the requirements across the speed range, the weighted coefficients are presented as functions of speed in a modified GPSO-LQG controller while constraint values α,β are given in the optimization of the weighted coefficients. Subsequently, simulation models are constructed with two working conditions. In the end, simulation results indicate that the modified GPSO-LQG controller reduces body acceleration by 8.37 % at a low speed and decreases the tire dynamic load by 8.55 % at a high speed, as compared with a GPSO-LQG controller. In terms of its outstanding advantages in improving the performance of suspension, the modified GPSO-LQG controller is more suitable for in-wheel motors suspension.

Authors: Li Zheng , Chen Qiushuo , Guo Peng , Wang Qunjing
Published: December 2018

Multi-degree-of-freedom motors have attracted more and more attentions, and the liquid suspension multi-degree-of-freedom PM motor is regarded as one of the research hotspots of new kind of electrical machine. In order to further optimize the structure of liquid suspension permanent magnet synchronous multi-degree-of-freedom motor and improve the stability of the operation, the mode force analysis of the motor's component is carried out. The characteristics and basic structure of the motor are introduced, and the principle and rules of the motor resonance are expounded in detail. Based on the theory of mechanics, the mode of the motor spherical shell is studied and calculated. By finite element analysis, the modal changes of stator shell under static and energized conditions are calculated and the comparison is made. Then, the 2nd order modal deformation of the spherical shell is monitored by hammering and sensor with the measured data obtained and compared with the finite element simulation. The solid mechanical structure of the claw stator core is analyzed so that the stress distribution and deformation displacement distribution are obtained. The results of the simulation and analysis provide the reference for the optimal design of this kind of motors or actuators.
Fault feature extraction for rolling element bearings based on multi-scale morphological filter and frequency-weighted energy operator
Authors: Zhu Danchen , Zhang Yongxiang , Zhu Qunwei
Published: December 2018

In order to extract impulse components from bearing vibration signals with strong background noise, a fault feature extraction method based on multi-scale average combination difference morphological filter and Frequency-Weighted Energy Operator is proposed in this paper. The average combination difference morphological filter (ACDIF) is used to enhance the positive and negative impulse components in the signal. The double-dot structure element (SE) is used instead of zero amplitude flat SE to improve the effectiveness of fault feature extraction. The weight coefficients of the filtered results at different scales in multi-scale ACDIF are adaptively determined by an optimization algorithm called hybrid particle swarm optimizer with sine cosine acceleration coefficients (H-PSO-SCAC). At last, as the Frequency-Weighted Energy Operator (FWEO) outperforms the enveloping method in detecting impulse components of signals, the filtered signal is processed by FWEO to extract the fault features of bearings. Results on simulation and experimental bearing vibration signals show that the proposed method can effectively suppress noise and extract the fault features from bearing vibration signals.

The phosphorus atom in hexamethyl phosphorus triamide 5 attacks the carbonyl function in
2-chloroquinoline-3-carbaldehyde 4a to give the bis-quinolinyl ethanone product 6. On the other hand,
quinoline ring-attack proceeds by the same phosphorus reagent upon reaction with 2-chloroquinoline-
3-aldoxime 4b yielding phosphonate 7. Meanwhile, the reaction of the tris-aminophosphine reagent 5
with 2-chloroquinoline- 3-(p-chlorophenyl)imine 4c affords the respective α-aminophosphonate 8.
Moreover, the attack by phosphine 5 on 2-chloroquinoline-3-imines 4d and 4e produces the respective
cyclic azophosphole derivatives 9a and 9b. [(2-chloroquinolin-3-yl)methylidene]propane dinitrile 4f
reacts with phosphine 5 to yield [(2-chloroquinolinen-3-yl) 2,2-dicyanoethyl]tetramethylphosphonic
diamide 10. Structural elucidations for the new products were based on compatible analytical and spectroscopic
data. Moreover, the structures assigned for compounds 7 and 9a were unambiguously confirmed
by X-ray crystallographic measurements. Biological evaluations indicated that compounds 4a,c
exhibit antibacterial potency against Gram-positive bacteria and 4a,c and 9a show activity against

The problem of cyberattacks reduces to the unwanted infiltration of software through latent vulnerable access points. There are several approaches to protection here. First, unknown or improper system states can be detected through their characterization (using neural nets and/or symbolic codes), then interrupting the execution to run benchmarks and observe if they produce the states they should. If not, the execution can be rewound to the last successful benchmark, all states restored, and rerun.

Methods:

This will only work for cyber-physical systems that can be rewound. Benchmarks will often include sensory information. The second approach is termed, “semantic randomization”. This is similar to the well-known compiler technique known as “syntactic randomization”. The significant difference is that different variants of the algorithm itself are being automatically programmed. Cyberattacks will generally not be successful at more than one variant. This means that cybersecurity is moving us towards automatic programming as a desirable consequence. Knowledge-Based Software Engineering (KBSE) is the way to achieve automatic programming in practice.

Discussion:

There is non-determinism in the execution of such systems, which provides cybersecurity. Knowledge-based algorithmic compilers are the ultimate solution for scalable cost-effective cybersecurity. However, unlike the case for the less-secure syntactic randomization, the cost-effectiveness of semantic randomization is a function of scale. A simple randomization-based automatic programming method is illustrated and discussed.

Conclusion:

Semantic randomization is overviewed and compared against other technologies used to protect against cyberattack. Not only does semantic randomization itself, or in combination with other methodologies, offer improved protection; but, it serves as the basis for a methodology for automatic programming, which in turn makes the semantic randomization methodology for cybersecurity cost-effective.

Introduction:

“Aldosterone breakthrough,” which is observed in patients receiving long term treatment with angiotensin blockade, is strongly associated with the increased risk of a declining glomerular filtration rate through the profibrotic actions of aldosterone. Sacubitril/valsartan is a newly created combination medicine (the angiotensin receptor blocker valsartan and the neprilysin-inhibitor sacubitril). Therefore, sacubitril/valsartan should have additional organ-protective actions besides the angiotensin blockade.

Methods:

In this study, we examined the renal protective effect of sacubitril/valsartan in a salt-sensitive hypertension model using angiotensin II type 1a receptor (AT1aR) knockout mice. An oral administration of 1% NaCl solution with sacubitril/valsartan (30 or 60 mg/kg/day) or valsartan (15 or 30 mg/kg/day) alone beginning 7 days before administration of aldosterone was examined in an aldosterone infusion AT1R knockout mouse model as an aldosterone breakthrough model.

Results / Conclusion:

A significant decrease in Blood Pressure (BP) was observed in the sacubitril/valsartan group compared to the valsartan group under low and high doses. In addition, the pathological analysis of the kidney for glomerular fibrosis by Sirius red staining and for injury by PAS staining demonstrated significant reductions accompanied by a significant reduction in TGF-β in the sacubitril/valsartan group compared to the valsartan group. Overall, sacubitril/valsartan, which has the dual actions of the AT1R blockade and neprilysin inhibition, may have additional clinical values for the treatment of hypertensive patients with aldosterone breakthrough.
Construction and Validation of an Online Subcritical Adsorption-based Device for Assisting CO2 Recycling during a Supercritical Fluid Extraction Process

Published: December 2018

Background:

An efficient process for extracting food ingredients from plant materials should demand the use of a reduced volume of extraction solvent to obtain a final product that is free of solvent and reduces both the processing time and the costs. In some cases, achieving a new efficient process requires the modification, reconfiguration or renewal of elements that are part of a processing unit.

Objective:

The goal of this work is to describe the development of a modification of a commercial supercritical fluid extraction pilot unit designed to assist CO2recycling based on subcritical adsorption on an adsorbent material. In addition to the construction and validation of the system, a cost survey was performed to estimate the cost of the homemade device developed to allow effective CO2recycling.

Methods:

The developed device was tested using cotton and Celite®as model adsorption materials and annatto seeds (Bixa orellana L.) as a model plant material. A 0.65 L adsorption column was installed with a set of connections and valves that complemented the unit’s recycle system. The validation procedure consisted of defatting annatto seeds.

Results:

The proposed online subcritical adsorption-based device was technically validated using cotton as an adsorbent material. The cost survey showed that an estimated total cost of USD 5731.36 would be required to install the developed device in a Supercritical Fluid Extraction (SFE) unit similar to the one coupled here (5 L).

Conclusion:

The proposed device was demonstrated to be very promising for application in the pseudocontinuous SFE, recirculating the same amount of CO2mass exceeding the S/F values by 14 times, when compared to a process without a CO2recycling system.
Single-Session Low Duration Panretinal Photocoagulation Using Conventional Laser on Central Subfield Macular Thickness in Diabetic Retinopathy
Authors: Kartasasmita Arief S , Yollamanda Prettyla , Ihsan Grimaldi , Virgana Rova
Published: December 2018

Objective:

To compare the change in central subfield macular thickness following single-session and multiple-session laser panretinal photocoagulation in subjects with diabetic retinopathy.

Methods:

A single-center, randomized controlled trial study was performed on 28 eyes of 16 patients with severe non-proliferative diabetic retinopathy or proliferative diabetic retinopathy. Eyes were randomly assigned for treatment with panretinal photocoagulation performed either in single-session or multiple-session divided into three sessions during two-week period. Central subfield macular thickness was quantified using spectral domain optical coherence tomography and changes at four weeks follow-up were compared to the baseline measurement.

Result:

Mean baseline central subfield macular thickness of 12 eyes underwent single-session and 16 eyes underwent multiple-session panretinal photocoagulation were 342.91+109.51 micrometers and 354+171.79 micrometers (p> .05), respectively. Mean post laser central subfield macular thickness in the single-session group was 305.83+81.95 micrometers and 389.75+229.51 micrometers in the multiple-session group (p> .05). Mean central subfield macular thickness changes four weeks post laser was 37.08+94.21 micrometers for eyes treated with single-session and -35.75+123.62 micrometers for the multiple-session treated eyes (p= .101).

Conclusion:

There was no significant difference in change of central subfield macular thickness at four weeks post laser from treatment with single-session and multiple-session panretinal photocoagulation. Single-session panretinal photocoagulation can be used as effective multiple-session panretinal photocoagulation for the treatment of diabetic retinopathy.

Authors: Hebi Morad , Eddouks Mohamed
Published: December 2018

Background:

Corrigiola telephiifolia Pourr, is a perennial species, woody distributed
throughout the north of Africa. This plant is used in traditional Mediterranean preparations and has
many traditional uses especially treatment of diabetes.

Aim/Methods:

The current research was carried out to evaluate the antidiabetic effect of Aerial Parts of
Aqueous Extract (APAE) of Corrigiola telephiifolia (C. telephiifolia) on both normal and streptozotocin
(STZ)-induced diabetic rats treated at a dose of 5 mg/kg for fifteen days. Additionally, the histopathological
changes in the liver, morphometric analysis, Oral Glucose Tolerance Test (OGTT) in normal
rats and preliminary phytochemical screening for various components were realized.

Results:

Single oral administration of the APAE of C. telephiifolia (5mg/kg) showed no significant
change in glycaemia of normal and STZ-induced diabetic rats. In contrast, repeated oral administration
of C. telephiifolia reduced blood glucose levels from 4.11 ± 0.10 mmol/L to 3.16 ± 0.16
mmol/L (p<0.01) 15 days after administration in normal rats. Furthermore, blood glucose levels decreased
from 17.84 ± 1.75mmol/L to 1.93 ± 0.33 mmol/L (p<0.0001) in STZ diabetic rats after fifteen
days of treatment. According to the oral glucose tolerance test, C. telephiifolia (5 mg/kg) was
shown to prevent significantly the increase in blood glucose levels in normal treated rats 30 min after
glucose administration when compared to the control group. Also, the liver architecture of diabetic
rats treated by C. telephiifolia was improved when compared with the liver architecture of untreated
diabetic rats. Concerning the preliminary phytochemical screening of C. telephiifolia, several
compounds have been found such as polyphenols, flavonoids, saponins, mucilage and terpenoids.

Conclusion:

The results show that the aqueous extract of C. telephiifolia possesses significant antihyperglycemic
activity.
