Authors: Uarova Ol'ga Vasil'evna , Rachkovskaya Larisa Alekseevna
Published: December 2019

The article examines genre and stylistic peculiarities of the TV talk show “Larry King Now”. The results of analysing stable and variable genre features of the American talk show are presented. The basic variable feature of this talk show is absence of the audience in the studio. The authors argue that entertaining presentation of informational and analytical content, peculiarities of linguistic arrangement impart individuality to Larry King’s show. It is shown that Larry King’s long-term experience as a talk show host helps to win the trust of the guests, popularity among the TV-viewers and allows distributing the program at TV channels of different countries and online.

Экспериментальная оценка цитотоксического, цитопротекторного и антиоксидантного действия экстракта каштана конского с 50 % содержанием эсцина
Authors: Федотчева Татьяна Александровна , Матюшин А. И. , Усенко А. Н. , Шейченко О. П. , Радимич А. Ю. , Шейченко В. И. , Федотчева Н. И. , Шимановский Н. Л.
Published: December 2019

Проведена сравнительная оценка токсического действия на опухолевые клетки DU145 (рак предстательной железы человека) и фибробласты кожи крыс экстракта каштана конского, содержащего 50 % бета-эсцина с синтетическим химически чистым эсцином («Sigma», США). Показано, что экстракт каштана конского в концентрации 0,3 мг/мл подавляет жизнеспособность опухолевых клеток на 16 % больше, чем эсцин в такой же концентрации (p < 0,01). Сравнение токсического действия экстракта конского каштана (ЭКК) и эсцина на фибробласты кожи крыс показало, что ЭКК не влияет, а эсцин ингибирует жизнеспособность фибробластов (на 29 %, p < 0,01, инкубация 24 ч). ЭКК снижает цитотоксичность цисплатина на 50 % при их совместном действии на фибробласты, проявляя цитопротекторные свойства, связанные, возможно, с наличием антиоксидантной активности. Эсцин не обладает антиоксидантной активностью как показано в АБТС-тесте in vitro и не оказывает цитопротекторное действие. Эсцин и ЭКК не защищают опухолевые клетки от рентгеновского облучения в дозе 1 Гр, а, наоборот, потенцируют его действие. Выявленное in vitro увеличение цитотоксичности облучения в присутствии экстракта каштана конского позволяет высказать предположение о возможности его использования в качестве потенциального противоопухолевого средства.

Aqueous and ethanolic extracts of propolis for the control of tyramine production by food-borne pathogens
Authors: BURĞUT Aykut
Published: December 2019

The influences of aqueous and ethanolic extracts of propolis (1%) on growth
of common Gram-negative (Salmonella Parathyphi A, Campylobacter jejuni, Yersinia enterocolitica and Klebsiella pneumoniae) and -positive (Listeria
monocytogenes, Staphylococcus aureus and Enterococcus faecalis) food-borne pathogens and their biogenic amines (BAs) production were examined in tyrosine
decarboxylase broth (TDB). The highest growth inhibitory activity was observed
against Gram-negative S. Paratyphi A
in the existence of ethanolic and aqueous  extracts of propolis, with 2.49 and 1.9 log
reduction, respectively. Ethanolic extracts of propolis were more effective
than that of aqueous  extract on growth
inhibition of L. monocytogenes (p<0.05). Both extracts of
propolis had significant effect on reducing ammonia production by bacteria
(p<0.05). Tyramine, dopamine, agmatine and spermine were major amines formed
in TDB. Tyramine production was the lowest with S. Paratyphi A (1.94 mg/L) and highest with E. faecalis (254.93 mg/L).
The existence of ethanolic propolis extracts in TDB led to
significantly fewer tyramine production by Gram-positive S. aureus, L. monocytogenes and E. faecalis, and Gram-negative C. jejuni (p<0.05). Histamine produced
lower than 1.3 mg/L by all food-borne pathogens. Ethanolic extracts of propolis
generally led to lower histamine production by bacteria. The influence of
propolis on BAs production varied according to type of extracts, specific BAs
and bacterial strains. However, the aqueous of propolis generally showed a synergistic
effect on most of BAs mainly tyramine production by bacteria. Thus, the use of propolis ethanolic extracts appeared
to be more suitable than aqueous extract to control
tyramine production in foods.

Authors: TAPLAMACIOĞLU Derya , KARACA İsmail
Published: December 2019

Pesticides have not only lethal effect on bees but they can also change
their navigational behaviors. The bumblebees exposed to pesticides may not find
their food and hive, and even their motor nervous system can acutely be
affected. In this study, effects of some pesticides (abamectin, acetamiprid,
deltamethrin, imidacloprid) on bumblebees were investigated. The bumblebee
colonies were obtained from Koppert Biological Systems, Inc., Turkey. Six doses
of each pesticide were tested on motor behaviors of some extremities of the
bumblebees and bumblebees were fed on only 50% sucrose as a control group to
compare with pesticide applications. Pesticides were applied to bees by feeding
and spraying methods. Then, the situations of motor mobility of legs, antennae
and proboscis extension of the bumblebees exposed to pesticides were scored.
According to the results of the study, the pesticides used in the experiment
had an impact on motor nervous system of the bumblebees, and the most effective
pesticide was imidacloprid, followed by deltamethrin, acetamiprid, and
abamectin, respectively. These results show that imidacloprid, all doses,
demage basic motor coordination fundamental to locomotion and foraging and kill
at label dose.

Authors: ÖZÇELİK Şehriban Gül , KARACABEY Erkan
Published: December 2019

In this study, it was aimed to investigate the
quality characteristics of fried zucchini slices pre-dried using osmotic dehydration
(OD) method at varying conditions (salt concentration, vacuum or ultrasound
application, time). Textural properties (hardness, elasticity, cohesiveness,
chewiness, firmness), surface color values (L*, a*, b*), moisture and oil
content of the final product were determined. Textural properties did not
change with OD applications (p>0.05). Vacuum and solution concentration
applied during OD method had significant effects on surface color values
(p≤0.05). OD did not cause any significant change in final moisture and oil
content of the fried product. In case of ultrasound assisted osmotic
dehydration (US-OD), it was seen that the effect of time on moisture content
was important  the solution concentration
of 5% (p≤0.05). On the other hand, changes at salt concentration have created significant
differences in both the application process (p≤0.001). When solution
concentration was 0%, effect of time was negligible to oil content (p>0.05).
Notwithstanding, the solution concentration for both processing time was found
to be significant (p≤0.05).

Authors: ÇALIK Esin , BALTACI Volkan , CANDOĞAN Prof. Dr. Kezban
Published: December 2019

Evaluation of some
meat quality attributes using genetic analysis is steadily increasing. PCR
based targeted variation analysis is one of the most commonly preferred
techniques for this purpose. Recently, Next Generation Sequencing (NGS) method has drawn
considerable attention because of its’ high
analysis capacity. The purpose of the current study was to
determine variations in CAST gene from Brangus and Simmental cattle by performing
whole gene sequencing using NGS, and to investigate the potential of NGS method
in evaluating meat tenderness based on the high genomic data it provides. Whole gene sequence analysis was performed on
Calpastatin (CAST) gene of samples acquired from 52 Brangus and 52 Simmental beef
cattle breeds using NGS method, and the variations detected were evaluated in
terms of their potential in measuring meat tenderness and quality. NGS
outputs were analyzed in Ensemble “cow” database platform and 13 variations were
detected. One of these variations (EXON 8 c.439C>G/ p.L147V ) was evaluated
as undeclared before. In 20 Brangus cattle and in 9 Simmental cattle, no variations
were detected whereas 6 variations (V1, V2, V5, V8, V10 and V13) were found significantly
different (p<0.05) based on their distribution in breeds.
Determination of the friction force and energy for Karacadağ local rice cultivars for different surfaces
Authors: ESGİCİ Reşat
Published: December 2019

The friction properties of grain products are one of the important
parameters that are considered in the design of transport, transmission and
storage structures and equipment. In addition, the friction force and
coefficients on different surfaces are important in the selection of the power
supply required for such design of structures and in the calculation of their
actual dimensions. These are the common materials used for handling and
processing of grains and construction of storage and drying bins. In this
study, the static friction force and static friction energy were measured on 4
different material surfaces (rubber, chrome, galvanized sheet and PVC) and 3
different moisture contents (9.30%, 18.50% and 29.00%) for Karacadağ Beyaz and
Karacadağ Karakılçık local rice varieties. The pulling of the grain box on the
surface and the friction forces and energy were measured at a constant speed of
20 mms-1 with Llyod tester having a capacity of 2500 N. There was no significant
difference between the varieties in terms of frictional force and friction
energy (p> 0.05). However, the effect of surface material and grain moisture
content was found to be very important (p <0.01). As the moisture content of
the grain increased, the static friction force and friction energy values
increased. The highest values were obtained in PVC and rubber material with a
moisture content of 29.00%, the lowest value was obtained in chromium material
and 9.30% moisture content.
La Tablada en enero de 1989 y sus efectos e impacto en Córdoba. Sobre la (re) estigmatización de las militancias en la historia reciente.
Authors: Solis Ana Carol
Published: December 2019

Las múltiples incidencias producidas a partir del acontecimiento de La Tablada, en enero de 1989, sobre las militancias en general y concretamente en Córdoba se reconstruyen mediante el análisis de las diferentes acciones y repercusiones institucionales y políticas que provocó. En particular, el artículo se interroga por las acciones de (re)estigmatización de las militancias ubicadas dentro de un universo político ideológico afín y/o cercano al grupo militante identificado como iniciador del evento, pero también para una cartografía más amplia de actores políticos y militancias organizadas. La contracara de esa estigmatización se analiza en el retorno de discursos de legitimación de la acción estatal represiva, aún atisbado el uso reiterado de metodologías afines al terror de Estado en democracia.
Ruptura, liberación y necesidad. El semanario Compañero y una lectura sobre la revolución en los sesenta del peronismo
Authors: Funes Andrés N.
Published: December 2019

Numerosas son las investigaciones académicas que buscaron comprender los contornos que adoptó el término revolución en las organizaciones políticas argentinas de finales de los sesenta y principios de los setenta, pertenecientes tanto a la izquierda peronista como también a la marxista. Sin embargo, un breve buceo por la bibliografía permite sostener que han escaseado las pesquisas orientadas a examinar los sentidos que el concepto de revolución tomó para el peronismo de los primeros años de la década del sesenta. Consciente de esta vacancia, este trabajo busca desentrañar los sentidos y significaciones que tomó el término revolución para un sector del peronismo, los “duros” o “combativos”, que se expresaban a través del semanario político Compañero a comienzos de los años sesenta. El artículo se ofrece como una vía de entrada inicial para comprender y complejizar el discurrir del peronismo en aquellos años.
THE USE OF HORIZONTAL GEOMAGNETIC FIELD COMPONENTS FOR ESTIMATION OF GEOMAGNETICALLY INDUCED CURRENT OVER TURKEY DURING SPACE WEATHER EVENTS
Authors: TİMOÇİN Erdinç , ERAT Selma
Published: December 2019

In this study, the time derivatives of the horizontal geomagnetic field components were computed to estimate the geomagnetically induced current (GIC) over Turkey during space weather events and the results were compared with the geomagnetic activity indices. The interplanetary magnetic field (IMF) index, disturbance storm time (Dst) index, global geomagnetic activity indices (ap and Kp) were used as indicator of space weather events. The changes because of solar flares and coronal mass ejections in the space environment between the Sun and Earth are defined as space weather events. Such events’ effects on the Earth's magnetosphere are called geomagnetic storms. In this study, two different space weather events that occurred on 20-26 June 2015 and 06-10 September 2017 are analyzed. The data of the horizontal magnetic field components used in the analysis are obtained from İznik magnetic observatory (40.5⸰N, 29.7⸰E). During space weather event on 20-26 June 2015, the maximum (max.) value of time derivative of (dX/dt and dH/dt) X and H horizontal magnetic field components were calculated as 72,22 nT/min. and 74,40 nT/min., respectively, while during space weather event on 06-10 September 2017, the max. value of the time derivative of the X and H horizontal magnetic field components are calculated and the results are 36,90 nT/min. and 38,12 nT/min., respectively. Also, it was observed that the strength of the local geomagnetic disturbance and amplitude of dX/dt and dH/dt at the observatory station depend strongly on the characteristics of geomagnetic activity indices during the space weather events. The southward IMF Bz component induces larger amplitude of dX/dt and dH/dt. The results indicate that the possibility of GIC occurrence over Turkey is quite high. Therefore, we strongly believe that further research and experiment on GIC for Turkey is important.
A NEW METHOD FOR THE MEASUREMENT OF SOFT MATERIAL THICKNESS
Authors: GULER Mustafa Tahsin , BİLİCAN İsmail
Published: December 2019

Thickness measurement is very critical especially in fabrication of micro and nano devices to determine the thickness of the layers. Stylus measurement is the easiest and most common technique that is being employed among the other thickness measurement methods. Micro-nano fabrication processes requires the usage of both rigid and soft materials. While thickness of a rigid material can be easily detected, thickness measurement of the soft materials presents some difficulties for standard stylus thickness measurement devices. Since the soft materials are deformed by the stylus due to the applied pressure, correct thickness measurement cannot be realized. Here, PDMS (Polydimethylsiloxane) is used as soft material for thickness measurement. By taking the replica of the soft material with liquid plastic which becomes rigid after curing, the depth can be measured easily via conventional stylus thickness measurement devices.

Ketimpangan pemilikan dan penguasaan tanah, di satu pihak ada individu atau kelompok yang memiliki dan menguasai tanah secara berlebihan namun di lain pihak ada yang sama sekali tidak mempunyai tanah. Ketimpangan inilah yang mengakibatkan semakin meningkatnya kesenjangan sosial di masyarakat sehingga membuat konflik pertanahan seakan-akan tidak ada habisnya. Penyelesaian konflik yang terjadi di masyarakat melalui proses berbasis masyarakat, peneliti temukan di beberapa daerah seperti Bali, konflik yang terjadi di masyarakat diselesaikan melalui lembaga adat yang dikenal dengan Majelis Desa Pakraman merupakan organisasi yang bersifat religius. Di Minahasa dikenal hukum tua yang menangani permasalahan di desa termasuk konflik pertanahan. Hukum tua adalah pemimpin desa milik semua warga.

GLOBALIZATION: A MIXTURE OF CULTURES AND DISADVANTAGING DEVELOPING COUNTRIES
Authors: Maya Lia
Published: December 2019

It is fair to say that the impact of globalization in the cultural sphere has, most generally, been viewed in a pessimistic light. Typically, it has been associated with the destruction of cultural identities, victims of the accelerating encroachment of a homogenized, westernized, consumer culture. This view, the constituency for which extends from (some) academics to anti-globalization activists (Shepard and Hayduk 2002), tends to interpret globalization as a seamless extension of - indeed, as a euphemism for - western cultural imperialism. In the discussion which follows I want to approach this claim with a good deal of skepticism.
Rethinking executive function development
Authors: Doebel Sabine
Published: December 2019

Research on executive function in early childhood has flourished in recent years. Much of this work is premised on a view of executive function development as the emergence of a set of domain general component processes (e.g., working memory updating, inhibitory control, and shifting). This view has shaped how we think about relations between executive function and other aspects of development, the role of the environment in executive function development, and how best to improve executive function in children who struggle with it. However, there are conceptual and empirical reasons to doubt that executive function should be defined in this way. I argue executive function development is better understood as the emergence of skills in using control in the service of specific goals. Such goals activate and are influenced by mental content like knowledge, beliefs, norms, values, and preferences that are acquired with development and are important to consider in understanding children’s executive function performance. This account better explains empirical findings than the components view; leads to specific, testable hypotheses; and has implications for theory, measurement, and interventions.
Validación de escala pronóstica de conversión a cirugía abierta en colecistectomía laparoscópica
Authors: Andrade Salinas Roberto Paúl
Published: December 2019

Introducción: La conversión a cirugía abierta es una complicación de la colecistectomía laparoscópica, ya sea por dificultad en la disección o por la falta de experticia del cirujano. Actualmente es complicado predecir la dificultad de una cirugía laparoscópica de vesícula biliar.

Objetivo: Evaluar la sensibilidad de la ecografía para colecistitis y colelitiasis y su relación con los hallazgos transoperatorios en cirugías de vesícula biliar

Material y Métodos: Se realizó un estudio observacional retrospectivo con la revisión de las historias clínicas de aquellos pacientes intervenidos quirúrgicamente por patologías de vesícula biliar y que presenten ecografía como medio diagnóstico en el Hospital General Docente Ambato de Junio a Diciembre de 2018.

Se evalúo la posible dificultad quirúrgica con una escala pronóstica ecográfica y posteriormente se comparó con los hallazgos quirúrgicos y la existencia de conversión.

Resultados: La correlación de la dificultad quirúrgica (cirugía mayor a 90 min o convertida) en relación con la escala predictiva (posible cirugía complicada score ≥5) es de 73% (sensibilidad) y la probabilidad que la escala prediga una cirugía no complicada es del 71% (especificidad), con un OR: 7.785 (IC: 0.789 – 78.511), con un test de Fisher (X2 modificado) de 2.225 con una p = 0.074. La relación no es estadísticamente significativa.

Conclusiòn La escala pronóstica ecográfica utilizada en los pacientes del Hospital General Docente Ambato no predice la dificultad quirúrgica de los pacientes sometidos a cirugía laparoscópica de vesícula
Persistencia de vena cava superior izquierda: ¿marcador ecocardiográfico de malformaciones fetales cardiacas y extra-cardiacas?
Authors: Vaca Nuñez Carlos Stalin , Deiros Bronte L , Vaca Pazmiño Carlos , Vaca Núñez A.
Published: December 2019

Introducción: La vena cava superior izquierda persistente (VCSIP) es la malformación vascular congénita más frecuente, observada en el 0.3% de autopsias en la población general y en el 4 -8 % de pacientes con cardiopatías congénitas.  Durante el desarrollo embriológico temprano el retorno venoso de la cabeza y los brazos normalmente drena en la aurícula derecha por las venas cardinales anteriores izquierda y derecha.

Objetivo: Relacionar la Persistencia de Vena Cava Superior Izquierda (VCSIP) diagnosticada por estudio ecocardiográfico fetal, con la presencia de anomalías intra y extracardiacas.

Metodología: Se realiza un estudio descriptivo, retrospectivo en 75 casos obtenidos de la base de datos del departamento de Medicina Perinatal del Hospital Universitario La Paz (Madrid –España), durante el periodo comprendido entre 2006 - 2017 con diagnóstico prenatal de (VCSIP). A los 75 pacientes se realiza estudio ecocardiográfico, a 32 amniocentesis y a 2 biopsia de velocidades coriónicas y, se establece su relación o no, con anomalías congénitas cardiacas y extracardiacas.  El análisis estadístico se realiza mediante el programa STATA.

Resultados: Se analizaron ecográficamente 75 fetos con diagnóstico de VCSIP, con una media de edad gestacional al diagnóstico de 26,6 semanas (DE: 5,87; IC: 95%). En 14 pacientes (18.67%) no se detectaron malformaciones; en 27 pacientes (36%) se evidenciaron alteraciones cardiacas; 15 pacientes   (20%), presentaron malformaciones extra cardiacas y 19 pacientes (25.33%), presentaron malformaciones extra e intracardiacas.

Conclusiones: La ecografía prenatal tiene un gran impacto para el diagnóstico temprano de afectaciones y variaciones anatómicas como la vena cava superior izquierda. El diagnóstico de esta alteración obliga a realizar despistaje y seguimiento de otras anomalías fetales asociadas ya sean intra y extra-cardiacas. Con un buen screening ecográfico prenatal no sería imperativo indicar a los pacientes con VCSIP aislada una prueba invasiva prenatal.
Cognitive impairment as a function of sleep quality and gender
Authors: Akhil R. , Nair B.P.
Published: December 2019

Background: The study aims at finding whether there is any significant difference between sub-groups classified on the basis of sleep quality (good sleep quality and poor sleep quality) and gender in the performance of various cognitive functioning tests like Visual N Back Test (N Back 1and N Back 2 test) for working memory, Triad test for divided attention, Digit Vigilance Test for sustained attention and Reaction time test (simple reaction time and choice reaction time).

Materials and methods: The sample consisted of 30 participants, both males (N=13) and females (N=17) in the age range between 18 to 30 years, randomly drawn from Thiruvananthapuram and Kollam districts of Kerala. The participants of the study are screened and categorized into two groups of 15 members each on the basis of the scores obtained in the Pittsburgh Sleep Quality Index (PSQI). t-test and two-way ANOVA were performed to test the significance of the hypotheses.

Results: The results showed that the participants with poor sleep quality significantly differed from those with good sleep quality and committed more number of errors in the triad test of divided attention and took more time and committed more errors in the completion of the digit vigilance test of sustained attention.

Conclusion: A gender advantage favoring females was seen on the test of working memory, test for sustained attention and the test for choice reaction time. An interaction between sleep quality and gender was noticed only on the test of divided attention. It was seen that males with poor sleep quality are more impaired in divided attention tasks than females with poor sleep quality.
