STUDY ON ANTIOXIDANT, ANTI-INFLAMMATORY AND HEPATOPROTECTIVE ACTIVITIES ON CARBON TETRACHLORIDE – INDUCED HEPATIC DAMAGE IN MICE OF TRANG TO (Ixora duffii) LEAF EXTRACT
Authors: Trang Dai Thi Xuan
Published: March 2019

Trang To (Ixora duffii) belongs to Ixora genus in the family Rubiaceae. The in vitro total antioxidant and anti-inflammatory capacity of Trang To methanol leaf extract was investigated by using phosphomolypdenum method and Bovine serum albumin denaturation test. The results have shown that Trang To methanol leaf extract possessed relatively high antioxidant activity, the value OD0,5 of Trang To (OD0,5 = 15,551 ± 0,344 μg / mL) was compared to that of the standard, trolox (OD0,5=2,315±0,083 μg/mL). The anti-inflammatory effect of Trang To leaf extract obtained in Bovine serum albumin denaturation test (EC50= 6,03±0,12μg/mL) was comparable to reference drugs, diclofenac sodium (EC50= 0,57±0,21µg/mL). The hepatoprotective activity of the methanol leaf extract of Trang To was investigated in mice which their livers were damaged by carbon tetrachloride (CCl4) mixed in olive oil (1: 4) at dose 2.5 mL/kg body weight/ day. The standard hepatoprotective agent is silymarin, was used at dose 16 mg/kg body weight during 4 consecutive weeks. The results of Trang To leaf extract was examined at three different doses 100, 200 and 400 mg/kg body weight all showed the effective reduction of transaminase enzyme levels in serum, with ALT levels (104,80±14,84 U/L, 84,20±20,02 U/L, 45,00±21,06 U/L) and AST levels (137,40±26,30 U/L, 119,20±6,40 U/L và 88,80±14,62 U/L) when increasing of the extract dose, respectively. In addition, Trang To leaf extract also improved the oxidative stress status in the liver through effective reduction of MDA level and increasing of GSH level in the liver. Observation of the microscopic cross section of liver tissue revealed that the mice treated with Trang To leaf extract had significantly improvement in liver tissues compared to the non-treated control group, these also showed similar results as silymarin at dose 16 mg/kg body weight. The results of this study demonstrated the efficacy of Trang To leaf extract in antioxidant and hepatoprotective activity.

Using chloroprene rubber waste in rubber blends: optimizing performance by adding fillers
Authors: Hayeemasae Nabil , Salleh Siti Zuliana , Ismail Hanafi
Published: March 2019

In the present study, chloroprene rubber waste (CRW) was used in an attempt to extend its use and create a value-added material based on natural rubber (NR) and CRW blends. Conventional fillers including carbon black (CB), silica (SS) and calcium carbonate (CC) were used individually to optimize the performance of the rubber blends. The properties evaluated were the curing characteristics, physical and dynamic properties and thermal stability. From the results obtained, it is clear that the type and amount of filler play a crucial role in promoting the performance of the blend. A faster curing rate was observed for the blends containing CB and CC, while SS-filled NR/CRW blends showed the opposite trend. SS-filled NR/CRW blends exhibited tremendously improved tensile properties compared with CB- and CC-filled blends. This is because two types of competing interactions/reactions take place: the dipole–dipole interaction between SS and CRW and the silane coupling reactions. The tensile properties are also in good agreement with the observed dynamic properties. A higher storage modulus and a lower damping factor were found in the blends containing CB and SS, indicating more restricted molecular mobility caused by rubber–filler interactions.
Cyclic behaviour of eccentrically braced frames fabricated with high-strength steel
Authors: Lian Ming , Su Mingzhou , Zhang Hao , Cheng Qianqian
Published: March 2019

This paper reports on a study performed on cyclic testing of two half-scale, one-bay, one-storey, Y-shaped, eccentrically braced frames fabricated with high-strength steel to investigate their hysteretic behaviour and performance, including the failure mode and load-bearing, ductility and energy-dissipation capacities. A comparison between experimental and finite-element model results was performed. In addition, non-linear analyses of the numerical models were carried out to investigate the effects of shear-link length on hysteretic behaviour. The test results indicated that the specimens had a good deformation capacity. The hysteretic curves were very full, implying the frames had significant energy-dissipation capacity. The frames are a safe dual system with useful hysteretic behaviour and seismic performance. The designed shear links dissipated the energy by way of shear deformation during cyclic loading. The numerical analysis indicated that shear-link length could influence the cyclic behaviour.
Effects of horizontal dilation of urban space on shading efficiency in the Muscat region
Authors: Khudhayer Wael A. , Shaaban Awni K. , Abdul Sukor Nur Sabahiah
Published: March 2019

The contemporary urban space of Muscat displays horizontal sprawl with overextended horizontal proportions causing pedestrian discomfort due to lack of solar shading in the hot environment. Urban space boundaries usually described by its floor and surrounding buildings, but in this work, was abstracted into basic hypothetical box formed of a floor and four fictitious walls. A mathematical model was developed to investigate the effect of dilation on the floor of urban space to identify the horizontal dilation limits that keep the walls’ shading feasible for the pedestrian in the hot climate. The study concludes that the dilation along E/W direction is relatively more efficient than N/S direction. A further conclusion is that the performance of urban spaces modules was not due to the accumulative performances of all walls, but instead, due to the combination-specific effective walls, the U-shape towards north was for the floor directed to the north. While, when the floor rotated 45° the efficient form was L-shape facing the north. In the case of existing urban spaces with immense horizontal proportions, it was suggested to partition the urban space into smaller areas by a vertical divider such as trees.
A New Approximation to Classify the Liquids Measured in Microwave Frequency Range
Authors: ÖZTÜRK Turgut
Published: March 2019

Different classification techniques have
been proposed to analyze the measurement results in order to show that the
liquids measured in the microwave frequency range can be separated. Furthermore,
it has been shown that the proposed process can be applied successfully with
different liquid quantities. Furthermore, the effect of different type
containers has been demonstrated. In this context, five different liquids have
been measured between 0.8-5 GHz in this study, by using ring resonator method. Thus,
the ability of the proposed model has been demonstrated by the success of the
measurement method and classification techniques.

The study assessed the antimicrobial and antioxidant activities of commonly used and commercially available essential oils as an alternative to synthetic preservatives. The plant sources were as follows: lavender (Lavandula angustifolia), tea tree (Melaleuca alternifolia), bergamot (Citrus bergamia) and peppermint (Mentha piperita). The antioxidant activity of essential oils was tested by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2´-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) methods. The microdilution broth susceptibility assay revealed that lavender and bergamot essential oils were more efficient in inhibiting the bacterial growth than other tested oils, with the minimum inhibitory concentration of 5 μg/mL. This study also reports the successful implementation of an electrostatic extrusion technique for encapsulating essential oils into alginate beads, which enables the essential oils to maintain their free radical scavenging ability over time.

El índice de miseria corregido por informalidad: una aplicación al caso de Venezuela
Authors: Perazzi Josefa Ramoni , Orlandoni Merli Giampaolo
Published: March 2019

Esta investigación propone una modificación al índice de miseria de Okun (IMO) adaptándolo a mercados con estas características, agregándole al nivel de desempleo el nivel de empleo en el sector informal (ESI). El estudio compara la evolución de diversos índices de miseria tradicionales en varias regiones durante las últimas décadas, haciendo hincapié en el caso venezolano, para el cual se estima también el nuevo índice propuesto. Los resultados muestran mejoras en el bienestar de los grupos de países considerados, que contrastan con el deterioro que el indicador experimenta en Venezuela. En términos generales, el IMO está dominado por el desempleo, excepto en Venezuela. Sin embargo, la preponderancia de la inflación sobre el desempleo en este país parece ocurrir por la subestimación que la tasa de desempleo hace de la situación del mercado laboral venezolano

Authors: Umar Ibrahim Khalil , Bashır Samir
Published: March 2019

Human perception of the information on the road signs
is a critical factor in determining the safe use of both the vehicle and the
interacting environment. A total of 30 road traffic signs which
includes10-warning, 10-regulatory and 10-informatory signs were evaluated using
190 questionnaires to determine comprehension level of road users in Kano. The
questionnaire was administered to both private and commercial drivers of
trucks, cars, tricycle, motorcycle, and
bicycle. Majority of the respondents are male (91.6%) which is due to the
disproportionate ratio between male and female drivers in Kano city and 90% of
them are youth below the age of 40 years showing that majority of the state
drivers are young people. The comprehension level was found to be good 79%. The
least comprehended signs in Kano are “park and ride” with comprehension level
of 54.7%, followed by “Narrow bridge” (60%), “line merge ahead” (62.1%),
“slippery road” (63.2%), “No entry for all vehicles” (70.5%). The signs with up
to 90% recognition were “fuel station”, “stop sign” and “school crossing”. Sex,
education, driving experience and type of vehicle used seems to affect the
comprehension level of drivers in Kano. Truck drivers have a poor understanding of the traffic signs lower
than all other classes of road users (65%).

Authors: TOPÇUL Mehmet Rıfkı
Published: March 2019

The aim of this study was to compare the antiproliferative effects of
baicalein which is a flavonoide on MCF-7 and MDA-MB-231 cell line. The
experiments were carried out with the evaluation of the parameters. Including
cell viability, cell index, mitotic index, labelling index and apoptotic index.
With the cell viability test, IC50 concentrations of baicalein for
MCF-7 and MDA-MB-231 cells were determined as 10 µM and 30 µM, respectively and
these concentrations were used in all experiments. The results showed that the
IC50 concentrations decreased the values of cell viability, cell
index, mitotic index and labelling index and increased the apoptotic index
value for both cell types. These decreases and increases are statistically
significant (p<0.01). In addition, curves of the graphs obtained from the
xCelligence Real-Time Cell Analysis System showed that baicalein has
cytoskeletal effects on MCF-7 cells and cytostatic effects on MDA-MB-231 cells.
The results obtained from this study suggest that baicalein can be used in
patients with luminal A and triple negative breast cancer in the clinic by
supporting the future studies due to its antiproliferative effects on MCF-7 and
MDA-MB-231 cells.

En esta investigación se analizan los elementos de la neuroplanificación presentes en el proceso estratégico de las universidades privadas del estado Zulia. Este trabajo se fundamentó en los postulados teóricos de Pittaluga (2015), Marafuschi (2014), Hill y Col (2011), Braidot (2010), Mintzberg (1999) y Bertalanffy (1980). En este estudio, tipificado como descriptivo, no experimental, transeccional y de campo, los datos se recolectaron a través de un cuestionario con escalamiento de frecuencias, sometido al juicio de expertos y cuya confiabilidad Alfa de Cronbach fue de 0.92. Los resultados demuestran que el pensamiento estratégico es el único elemento de la neuroplanificación que casi siempre está presente en el proceso estratégico de las universidades estudiadas, sin embargo, algunos de los otros elementos presentaron un moderado nivel de ocurrencia, lo cual conlleva a que la gerencia de estas instituciones deban atender realidades internas que le permitan fortalecer las habilidades estratégicas en su personal directivo, por cuanto, la efectividad de todo proceso estratégico no descansa solo en que los líderes tengan un pensamiento visionario, sino, además, en la puesta en práctica constante del análisis integral del todo y sus partes, la aplicación continua de la creatividad, el estudio de diversos modelos de éxitos que ofrece el entono
Using metaphor to explore the organizational patterns of expository writing
Authors: Castaño Emilia , Verdaguer Isabel , Hilferty Joseph
Published: March 2019

Writing is a complex and multifaceted task that presents many challenges, especially when writing in a foreign language. Recent studies have shown that writers and readers benefit from explicit knowledge of text genres and their organization, since the sense of unity that is sought in a text is largely connected to its overall structure. Awareness of text structure informs about conventions of structure that control the flow of information and determine the kinds of cues available to readers. In the present article, we use conceptual metaphor theory to provide a new way of exploring the activity of writing in the academic context and tap into the conceptual frame that writers and readers of expository texts may employ to organize information. In this sense, we illustrate how the texts are journeys metaphor can be used to elucidate the rationale behind the macro-structural organization of expository texts written by non-expert EFL writers.

En el presente estudio se compara la eficacia para remover el barrillo dentinario de dos sistemas de irrigación final usados en Endodoncia. La capacidad de remoción de barrillo dentinario otorgado por la irrigación final con EDTA al 17% seguida de hipoclorito de sodio (NaOCl) al 5.25% se compara con el grado de remoción de barrillo dentinario otorgado por la irrigación final con Qmix. Los irrigantes tendrán un tiempo de acción de 1 minuto y medio en el interior de los conductos. Este estudio se hará con ayuda de imágenes obtenidas del microscopio electrónico de barrido de cada una de las piezas dentales sometidas al debido protocolo de irrigación final. Para realizar este estudio se escogieron 18 dientes unirradiculares entre premolares y molares extraídos por fines ortodónticos. Posteriormente a la remoción de la corona clínica de cada diente, se instrumentaron los conductos radiculares siguiendo la técnica de instrumentación rotatoria Protaper. Los conductos fueron constantemente irrigados con hipoclorito de sodio al 5.25% luego de cada lima. Posteriormente, los dientes se dividieron aleatoriamente en tres grupos distintos (control positivo, irrigación final con EDTA y NaOCl e irrigación final con Qmix). Finalmente, los conductos se sometieron a la irrigación final con los dos sistemas de irrigación escogidos para el estudio. Una vez la irrigación final realizada, se procedió a seccionar los dientes en sentido longitudinal para obtener dos hemisecciones de cada una de las piezas. Se escogió la mejor hemisección, la más íntegra, y se la llevó a estudio bajo microscopio electrónico de barrido. Las fotografías obtenidas del microscopio electrónico de barrido fueron sometidas a análisis cuantitativo de comparación de áreas de túbulos dentinarios sin barrillo dentario taponando su entrada. Los porcentajes de remoción de barrillo dentario fueron sometidos a análisis estadístico (sistemas estadísticos Anova y Tukey) y se llegó a la conclusión que el Qmix otorga mejores resultados para la remoción del barrillo dentinario que la irrigación final con EDTA al 17% seguida de NaOCl al 5.25%.

La periodontitis apical refractaria es una lesión periapical persistente en los tejidos perirradiculares de una pieza dental tratada con endodoncia. El origen infeccioso de la persistencia de las lesiones periapicales es un tema controversial y desafiante en odontología. El punto de vista tradicional sobre este tema defiende la escasa presencia o ausencia de microorganismos en los tejidos. Sin embargo, existe evidencia de la presencia de bacterias, levaduras y virus en dichas lesiones. El objetivo de esta investigación es realizar un estudio de casos y controles para comprobar la presencia de microorganismos viables en las lesiones y asociar esta presencia a la causalidad de las mismas. Utilizando microscopia y métodos moleculares se pudo comprobar la presencia de microorganismos en 16 (80%) de 20 muestras de casos de lesión persistente (0R: 136, IC 95%: 14-317) y en 1 (3%) de 35 muestras de tejido sano (OR: 0,074, IC 95%: 0,0008-0,071), de esta manera asociando a los microorganismos identificados como un factor causal de la fisiopatología de la periodontitis apical refractaria.

Introduction:
This
study aimed to describe the relationship between activities of daily living and
cognitive function community-dwelling elderly in an urban area.

Materials
and Methods: Participants were 872 randomly selected people aged ≥65 years living in Kayseri, Turkey, who were registered with
Family Health Centers. We used the
Standardized Mini-Mental State Examination (SMMSE) to assess participants’
cognitive function, the Katz Index of Independence in Activities of Daily
Living (ADL) to assess activities of daily living, the Instrumental Activities
of Daily Living (IADL) scale to assess instrumental activities of daily living,
and a questionnaire to assess sociodemographic characteristics.

Results: Participants’ mean age was 71.9±5.5 years.
The overall prevalence of IADL dependency was 17.6%; dependency was
significantly higher in women than in men (by 5.5%). The prevalence of ADL
dependency was 0.6%, and there was no sex difference. SMMSE and IADL scores
decreased as age increased, whereas the ADL score did not change.

Conclusions:
Increased
age is a fundamental component of cognitive impairment and limitation in
activities of daily living. Community-dwelling adults aged ≥65 years with cognitive impairment should receive early
evaluation for IADL dependency. In addition, a daily living activity
scale that takes into account social, cultural and gender characteristics may
be useful in early detection of dependence.

Published: March 2019

Amaç: Bu çalışmada sistemik inflamasyon ile ilişkili bir marker olduğu gösterilen; Nötrofillenfosit oranı (NLR), platelet-lenfosit oranı (PLR), ortalama trombosit hacmi (MPV) ve Eritrosit dağılım hacmi (RDW) ile akut pankreatitin (AP) başvuru anındaki ciddiyetini gösteren Ranson kriteri ile aralarındaki ilişkinin gösterilmesi amaçlanmıştır.Gereç ve Yöntem: Ocak 2017 ile Kasım 2018 tarihleri arasında AP tanısı ile takip eden hastaların verilerine retrospektif olarak ulaşıldı. 82 biliyer ve 15 nonbiliyer olmak üzere toplam 139 hasta çalışmaya alındı. Hastaların ilk başvuru anında bakılan hemogram ve biyokimyasal parametreleri, yaşları, cinsiyetleri, ko-morbiditeleri ve yatış süreleri kaydedildi. İlk başvuru anında bakılan Ranson Kriterlerine göre skoru < 3 ve skoru ≥ 3 pozitif olanlar olmak üzere 2 gruba ayrıldı ve bu gruplar karşılaştırıldı.Bulgular: AP tanısı ile takip edilen 139 hastanın 75 (%54)’i erkek, 64 (%46)’ü kadındı. Hastaların 113’ü Ranson kriterlerine göre 3’ün altında 26’sı ise 3 ve üzerindeydi. Ortalama yaş hafif AP grubunda 61±20 yıl, şiddetli AP grubunda ise 70±13 yıldı. MPV (P< 0.001) ve NLR (P< 0.001) değerleri gruplar arasında anlamlı olarak farklı saptandı. Korelasyon analizinde; NLR ile ranson skoru arasında pozitif korelasyon saptandı (r= 0,253 p<0,01). Yapılan Lineer Regresyon analizi sonucunda, NLR ve PLR’nin AP şiddetini göstermede bağımsız prediktör oldukları bulundu.Sonuç: Sistemik inflamasyonu gösteren çalıştığımız parametrelerden NLR, AP’nin şiddetini belirlemede basit ve güvenilir bir gösterge olarak kullanılabilir

Authors: KARAGÜN Ebru
Published: March 2019

Amaç: Nötrofil lenfosit oranı (NLO)- Trombosit lenfosit oranı (TLO), eritrosit dağılımdeğişikliği (RDW) , ortalama trombosit hacmi (OTH) düzeyleri sistemik inflamasyonun birgöstergesi olabileceği ve birçok kardiyovasküler hastalık, maliniteler, romatolojik hastalıklar,enfeksiyon hastalıklarında prognoz ve mortalite ile ilişkili olabileceği son yıllarda yapılançalışmalarda gösterilmiştir. Bu çalışmanın amacı sistemik kronik inflamatuar bir hastalıkolan psoriazis hastalarının sistemik tedavi öncesi ve tedavinin 12. haftasında PAŞİ(PsoriatikAlan Şiddet İndeksi)75 değerine ulaşan hastalarda Lökosit, Nötrofil, Trombosit, NLO, TLO,OTH ve RDW düzeylerindeki değişimi incelemektir.Gereç ve Yöntem: Metotreksat(Mtx)- Siklosporin- Asitretin- dbUVB- İnfiksimab veAdalimumab tedavisi başlanan kronik plak psoriazisli 60 hastanın hematolojik parametreleriincelenmiştir. Tedavi öncesinde ve tedavinin 12. haftasında PAŞİ75 değerine ulaşanhastaların Lökosit, Nötrofil, Trombosit, NLO, TLO, OTH ve RDW düzeylerideğerlendirilmiştir.Bulgular: Hastaların başlangıç PAŞİ değerleri 16,68±6,5 (Min:6,6,Max:29,6). Tedavisonrası lökosit, nötrofil ve trombosit ortalamaları tedavi öncesi ortalamalara göre anlamlıderecede düşüş gösterirken (p=0,01; p<0,001; p<0,001), tedavi öncesi ve sonrası lenfosit,OTH ve RDW ortalamaları arasında istatistiksel olarak anlamlı bir farklılıkgözlenmemiştir(her biri için p>0,05). Tedavi sonrası NLO ve TLO ortalamaları tedavi öncesiortalamalara göre istatistiksel olarak düşük bulunmuştur (p=0,043; p=0,009). Tedaviseçeneklerine göre tedavi öncesi ve sonrası ortalamalar karşılaştırıldığında MTX nötrofil,trombosit ve RDW üzerine etkili olmuşken, Asitretin ve Siklosporin nötrofil ve OTH üzerineetkili olmuştur. dbUVB tedavisi verilen hastalarda tedavi öncesi ve tedavi sonrasıortalamalar arasında anlamlı farklılık gözlenmemiştir.Sonuç: NLO ve TLO düzeylerinin tedavi sonrasında anlamlı farklılık göstermesi literatürdeyapılan çalışmalarla benzerlik göstermektedir. Çalışmada verilen sistemik tedaviajanlarından kardiyovasküler risk belirteçleri olarak bilinen hematolojik parametreler üzerineen etkili ilacın Mtx olabileceği düşünülmektedir
