AbstractThe subiculum is the main target of the hippocampal region CA1 and is the principle output region of the hippocampus. The subiculum is critical to learning and memory, although it has been relatively understudied. There are two functional types of principle neurons within the subiculum: regular spiking (RS) and burst spiking (BS) neurons. To determine whether these cell types are differentially modified by learning-related experience, we performed whole-cell patch clamp recordings from male mouse brain slices following contextual fear conditioning (FC) and memory retrieval relative to a number of control behavioral paradigms. RS cells, but not BS cells, displayed a greater degree of experience-related plasticity in intrinsic excitability measures [afterhyperpolarization (AHP), input resistance (Rinput), current required to elicit a spike], with fear conditioned animals having generally more excitable RS cells compared to naïve controls. Furthermore, we found that the relative proportion of RS to BS neurons is modified by the type of exposure, with the lowest proportion of BS subicular cells occurring in animals that underwent contextual FC followed by a retrieval test. These studies indicate that pyramidal neurons in the subiculum undergo experience- and learning-related plasticity in intrinsic properties in a cell-type-specific manner. As BS and RS cells are thought to convey distinct types of information, this plasticity may be particularly important in encoding, consolidating, and recalling spatial information by modulating information flow from the hippocampus to cortical regions.

Background: Cyclosporine (CYC) is an immunosuppressant drug used widely in kidney transplant patient. The major side effect of CYC is nephrotoxicity. In this study, three different doses of CYC alone or accompanied with zinc (Zn) supplement were administrated in male and female rats to determine the kidney tissue damages and functions.
Methods: Male and female rats were treated with 10, 50 or 100 mg/kg/day of CYC alone or accompanied with 10 mg /kg/day of Zn sulfate for 10 days. The parameters related to renal function were determined and the kidney tissues were subjected to histological evaluation.
Results: All male and female animals were treated with high dose CYC (100 mg/kg/day) alone or accompanied with Zn supplement during the experiment. The data obtained for the serum levels of creatinine (Cr) and blood urea nitrogen/Cr ratio, clearance of Cr, kidney weight (KW), sodium (Na) filtration rate, Na excretion rate and Na excretion fraction (%) in surviving animals suggest a role of gender in the variation of these factors. The kidney tissue damage score (KTDS) was increased as the dosage of CYC was elevated, and the Zn supplement attenuated the KTDS in animals treated with low dose CYC (10 mg/kg/day).
Conclusion: The CYC-induced nephrotoxicity may be gender-related, and the 10 mg/kg dose of Zn sulphate as a supplement may possibly prevent the induced nephrotoxicity in males due to its antioxidant effects.

Published: December 2018

Background and aimsInternet Addiction (IA) has consistently been related to comorbid psychiatric disorders and lowered self-esteem. However, most studies relied on self-report questionnaires using non-representative samples. This study aims to analyze the relative impact of self-esteem and comorbid psychopathology with lifetime IA in a population-based sample of excessive Internet users using clinical diagnoses assessed in a personal interview.MethodsThe sample of this study is based on a general population survey. Using the Compulsive Internet Use Scale, all participants with elevated Internet use scores were selected and invited to a follow-up interview. Current DSM-5 criteria for Internet gaming disorder were rephrased to apply to all Internet activities. Out of 196 participants, 82 fulfilled the criteria for IA. Self-esteem was measured with the Rosenberg’s Self-Esteem Scale.ResultsSelf-esteem is significantly associated with IA. For every unit increase in self-esteem, the chance of having IA decreased by 11%. By comparison, comorbidities such as substance-use disorder (excluding tobacco), mood disorder, and eating disorder were significantly more likely among Internet-addicted than in the non-addicted group. This could not be reported for anxiety disorders. A logistic regression showed that by adding self-esteem and psychopathology into the same model, self-esteem maintains its strong influence on IA.Discussion and conclusionsSelf-esteem was associated with IA, even after adjustment for substance-use disorders, mood disorder, and eating disorder. Self-esteem and psychopathology should be considered in prevention, intervention measures, as well as in the conception of etiological models.

Milletlerin
hayatında ad verme/adlandırma önemli bir yer işgal etmektedir. Her toplum
çocuklarına vereceği isimden başlamak üzere, yapmış olduğu işlere, yaşadığı
mekânlara, ürettiği ürünlere, yazdığı veya yaptığı esere varıncaya kadar her
şeyi isimlendirme ihtiyacı duymuştur. Toplumlar, geçmişlerini, atalarını,
kahramanlarını ve tarihteki önemli olaylarını çocuklara, mekânlara, kurumlara
vs. ad olarak vererek geçmişle bağ kurmaya ve kurulan bu bağı da diri tutmaya
çalışırlar.

Bu
araştırmanın amacı, Türk Dili ve Edebiyatı öğretmenlerinin şair ve yazar
isimlerinin ortaöğretim kurumlarına ad olarak verilmesinin Türk Dili ve
Edebiyatı öğretimine katkı sağlayıp sağlamadığına dair düşüncelerini
belirlemektir.

Nitel
araştırma yöntemleri ve durum çalışması deseninden faydalanılan bu çalışma,
Ankara ili merkezinde bulunan Abdurrahim Karakoç Anadolu Lisesi (Keçiören),
Halide Edip Mesleki ve Teknik Anadolu Lisesi (Yenimahalle), Yunus Emre Mesleki
ve Teknik Anadolu Lisesi (Yenimahalle), Ömer Seyfeddin Anadolu Lisesi
(Çankaya), Yahya Kemal Beyatlı Anadolu Lisesi

ana tema altında toplanmıştır. Bunlar, “okullara yazar ve şair isimleri vermek;
ismi verilenlerin edebiyat öğretimindeki yeri; ismi verilenlerle ilgili
okullarda yapılanlar ve öğrenciler açısından ismi okullara verilen
sanatçılar”dır.

Araştırma
sonucunda katılımcılar, “bu uygulamanın devam etmesi; öğrencilerin ilgili şair
ve yazarla ilgili meraklarının arttığı, buna karşılık uygulamanın öğrencilerin
okul tercihlerine etki etmediği” düşüncelerini ifade etmişler; katılımcıların
bir kısmı okullarına isimleri verilen sanatçıların ders öğretim programındaki
yeri ve bu isimlerle ilgili okullarda yapılan faaliyetleri “yeterli” görürken,
bazı katılımcılar ise “yetersiz” bulmuşlar; bu yetersizliği gidermek için ilave
çaba harcanması gerektiğini ve öğrencilerin bu husustaki farkındalığının
istenilen seviyede olmadığını belirtmişlerdir.

Published: December 2018

<p>Эпоха технического репродуцирования ставит перед исследователем проблему представления информации об искусстве. Поиск методологических ключей к анализу неисчислимого множества аналоговых и цифровых копий художественных памятников актуализирует поставленную М. Фуко в рамках археологии знания проблему архива. Концептуализация искусства как архива была обозначена представителями визуальных исследований (Visual Studies), которые показали, что история искусства, осмысленная как архив, представляет собой визуальный конструкт, отражающий особенности культурного сознания и рождающий новые уровни интерпретации художественных памятников. В статье проблематизируются возникшие в ХХ в. архивы искусства, которые были связаны с осмыслением роли фотографии.</p><p>Наиболее важными примерами работы модернистского сознания с архивом искусства являются серия панелей с фотографиями художественных памятников Аби Варбурга, названная автором Атласом «Мнемозина», и богато иллюстрированные альбомы репродукций мирового искусства под общим названием «Воображаемый музей» Андре Мальро.</p><p>Эти архивы могут быть оценены как ментальное пространство, в котором знаки артефактов включаются в виртуальные связи и формируют новые ценностные смыслы. Утрата подлинности и деконтекстуализация произведений искусства компенсированы созданием смыслопорождающих контекстов, отразивших новые алгоритмы конструирования исторического знания. Являясь противоположностями как в содержательном, так и в структурно-семантическом плане, Атлас и Альбом представили две пространственно-временные модели формирования исторических знаний и восприятия искусства. Если Атлас сформировал модернистскую исследовательскую парадигму искусства, то Альбом знаменовал рождение нового образа истории искусства в широком культурном пространстве. Предпринятый анализ показал, что и Атлас, и Альбом могут быть определены как визуальные конструкты, позволяющие характеризовать историческую модель видения.</p>
Социокультурные эффекты медиатизации телевидения
Authors: Полуэхтова Ирина Анатольевна 
Published: December 2018

<p>В статье анализируются изменения в социальном функционировании телевидения в контексте медиатизации и социокультурные последствия этих изменений, связанные со снижением социализационного потенциала телевидения, его роли в формировании единого информационного и культурного пространства и интеграции общества. В качестве эмпирической базы использованы результаты социологического исследования «Телевидение глазами телезрителей» (2000–2018), которое проводится под руководством автора статьи, а также вторичный анализ данных мониторинговых измерений телевизионной аудитории (компания «Медиаскоп»).</p><p>Телевидение (наряду с другими массмедиа) является, несомненно, важнейшим источником и инструментом медиатизации общества. Но и сам институт телевидения претерпевает кардинальные изменения, которые проявляются на разных уровнях. Основным фактором, оказывающим влияние на медийное поведение современных аудиторий СМИ, является цифровое неравенство. Вследствие этого в аудитории телевидения сегодня можно выделить несколько поколений телезрителей с разным медийным поведением.</p><p>Одним из эффектов медиатизации телевидения является индивидуализация телепотребления. Цифровой разрыв разрушает прежний механизм «воспроизводства» телевизионной аудитории. Цифровые трансформации российского телевидения происходят медленнее, чем развитие инфраструктуры и медийных сервисов Интернета, а также изменения в аудитории и практиках медиапотребления. Фрагментация аудитории может оказаться процессом с нежелательными социальными последствиями, поскольку ведет к еще большей раздробленности информационного пространства и публичной сферы.</p><p>Отмечается сильная зависимость российского телевидения от государства, с одной стороны, и рекламной бизнес-модели — с другой. Данные опросов фиксируют снижение интереса современной молодежи к телевидению как источнику развлекательного контента и заметно возросшее число молодых людей, включающих телевизор «по привычке» и «для фона». Это свидетельствует о глубинных сдвигах в восприятии телевидения как медиа. </p><p>В этих условиях снижается предсказуемость воздействия телевидения на формирование мировоззренческих установок и ценностных ориентаций россиян.

Over the past 3 years, an analysis of surgical treatment of 48 patients with unstable fractures of pelvic bones has been performed. The study group included patients with type B3, C2, and C3 fractures according to AO classification. The average follow-up period after the operation was 1 year.
Evaluation of the results of treatment was carried out on the basis of clinical examination, the analysis of radiographs and Mattis evaluation scale. Good results (76%) were obtained in patients with pelvic fractures type B3, C2, according to the AO classification. The number of satisfactory and unsatisfactory results of 15% and 9%, respectively, was obtained in patients in the group with the heaviest damage type C3. Complications of festering, impaired stability of fixation with loss of reposition were observed in 5 people (9%), two patients from the 3rd group died.
The obtained data allows to draw a conclusion that submersible osteosynthesis using various designs performed at the earliest possible time (damage control) remains the gold standard for today in the treatment of unstable fractures of the pelvis. The greatest number of complications was observed in the group of vertically unstable fractures of the pelvis C3. The data obtained correlates to a certain extent with the data of domestic and foreign literature.

Objective: The purpose of our study was to compare the biomechanical properties of the «spondylosyndesis-270» and «spondylosyndesis-360» fusion methods and make a conclusion about the possibility of the clinical use of «spondylosyndesis-270».
Mаteriаls аnd Methods. Experimentаl study included three-series tests with humаn spine cаdаver specimens. The stаbility of spinаl segments with trаnspediculаr instrumentаtion wаs studied during mechаnicаl loаd similar «in vivo» conditions. We used a torsion and tensile load on cadaver discs and investigated the stability of screw fixation in both methods.
Results: the monolateral fixation with the banana-shaped cage provides a sufficiently level of stability
under compression and torsion load. However, the outcomes of the monolateral method of fusion was better. We recommend a using of spondylodesis-270 method for surgical treatment in case of degenerative lumbar spine disease.

Aortic valve replacement is the second most common cardiac surgery procedure. Prosthesis-patient size mismatch can increase the incidence of adverse events postoperatively, it also leads to increased left ventricular load. Some studies describe the higher mortality in this group of patients. It is also proved that patients with severe aortic stenosis usually have impaired platelet aggregation and low von Willebrand factor causing bleeding disorders.
We report a case of successful aortic valve replacement and aortic root enlargement (Nicks technique) combined with coronary artery bypass grafting (left internal mammary artery to the left anterior descending artery) and left atrial appendage resection in 73-y.o. obese female patient. Postoperative course was uneventful.
La Tonadilla de Noé: la tortuga y la ballena, protagonistas del diluvio universal en un cuento de María Teresa León
Authors: Núñez Molina María Lourdes 
Published: December 2018

Algunos cuentos de María Teresa León están protagonizados por animales que el lector relaciona con fábulas y cuentos populares (el oso, el lobo, el zorro, el águila…), pero sus historias suelen ser innovadoras. Así sucede en «La Tortuga 427» (publicado en Rosa-Fría, patinadora de la luna, 1934), donde la autora reescribe el mito del diluvio universal, destinando un papel crucial a dos animales literarios: uno vinculado con las fábulas ―la Tortuga―, otro con los bestiarios ―la Ballena―, para transmitir un mensaje moral. Además, destacaré cómo los recursos lúdicos contrastan con el desilusionado desenlace, conectando con textos posteriores de la autora. Some María Teresa León’s tales are starred by animals that the reader related to fables and folktales (bear, wolf, fox, eagle...), but their stories are often innovative. This happens in «La Tortuga 427» (published in Rosa-Fría, patinadora de la luna, 1934), where the author rewrites the Flood myth, allocating a crucial role to two literary animals: one linked with the fables ―the Turtle― the other with the bestiary ―the Whale―, to convey a moral message. In addition, I will highlight how the recreational resources contrast with the disappointed outcome, connecting with later texts of the author.
Tu rostro con la marea: una tragedia con máscaras pero sin héroe
Authors: Ramón García Emilio 
Published: December 2018

Tu rostro con la marea es una metaficción historiográfica a modo de novela de memoria cuyo personaje principal, Ángel Bigas, se construye una imagen de héroe decimonónico. Incapaz de lidiar con la realidad,forja su vida según los mundos de escritores como Galdós, Maupassant y Stendhal, y según el modelo de amor romántico platónico hacia una mujer rusa, Olga Rykova Anneski. Incapaz de entenderla también a ella, la encaja dentro de las tesis del marqués de Custine respecto al pueblo ruso y sus tradicionales ataduras. Ella, por su parte, es el alter ego de la poeta rusa Ajmátova, y oculta un espíritu bolchevique tras su máscara. El análisis de sus figuras revela la relación entre la historia y la ficción, el carácter de tragedia clásica de la novela, el papel de las expectativas en la percepción, y el correlato de ambos con la historia de Europa. Tu rostro con la marea is piece of historiographical metafiction following the model of a memory novelaround its main character. Incapable of facing reality, Ángel Bigas projects the image of a nineteenthcentury hero according to the lives and works of Galdós, Maupassant and Stendhal while fueling hisaura with rumors and legends. His belief in the idiosyncrasy of the Russian people as understood by themarquis of Custine also makes him fail understanding his idealized love, Olga Rykova Anneski. She is also the alter ego of a very different kind of writer: the Russian Bolshevik poet Akhmatova. The analysisof the two figures as literary constructs reveals the relation between history and fiction, the natureof the novel as a classical tragedy, the role of expectations in perception and the direct relation of bothcharacters with the history of Europe.

Background: Female students are exposed to unsafe sex, sources of unwanted pregnancy and abortions. It is recognized that emergency contraception can effectively prevent pregnancy. The purpose of this study was to evaluate the knowledge and practices of Ouagadougou public university students in relation to emergency contraception in order to propose solutions to reduce the proportion of unwanted pregnancies among female students.Methods: This was a cross-sectional study conducted between May 1st and October 31st, 2016 in the public universities of Ouagadougou. A questionnaire was administered to a sample of 732 students randomly selected.Results: The average age of female students was 22.7 years old. The age group 19 to 24 was the most represented (68.03%). Of the students surveyed, 87% knew or had heard of emergency contraception. The students only used the emergency contraceptive pill. The emergency contraceptive use rate was 44.42%. Approximately, 83% of users were aware of the delay in using emergency contraception. The reasons for using emergency contraception were condom breakage (25.10%) and unprotected sex (74.9%). Female students purchased the contraceptive directly in pharmacies (93.61%).Conclusions: Emergency contraception gives women a last chance to avoid an unwanted pregnancy after unprotected sex. Awareness and free availability of emergency contraception (EC) could improve the reproductive health of female students.
