Неконвенційний міозин 1с як маркер апоптозу автореактивних клітин при розсіяному склерозі
Authors: Negrych N.O.
Published: April 2017

З метою пошуку нових маркерів розсіяного склерозу (РС) було проведено порівняльний аналіз вмісту у сироватці крові хворих на РС та практично здорових донорів 48 кДа ізоформи неконвенційного міозину 1с (48 кДа Myo1c). Матеріали та методи. У дослідженні взяли участь 61 хворий на РС та 20 практично здорових осіб віком від 19 до 57 років. Методи дослідження. Клінічні — аналіз скарг, анамнезу захворювання та життя, загальний і неврологічний огляди; лабораторні — шляхом послідовного зсідання сироваткових білків, електрофорезу та цифрового аналізу отриманих електрофореграм у сироватці крові хворих на розсіяний склероз визначають вміст 48 кДа Myo 1c, при цьому наявність Myo1c підтверджують за допомогою вестерн-блоту з антиMyo1c антитілами. Результати та обговорення. У сироватках крові хворих на РС та здорових донорів виявили 48 кДа Myo1c. Встановили, що у сироватці крові хворих на РС рівень 48 кДа Myo1c був вірогідно вищим порівняно з групою практично здорових осіб. Зважаючи на те, що ключову роль в процесах набуття автореактивності при РС відіграють Т-лімфоцити, вірогідно підвищений рівень 48 кДа Myo1c, що міститься у значній кількості в активованих лімфоцитах, свідчить про посилену загибель цих клітин шляхом апоптозу. Визначили, що вік хворих у групі з високим рівнем 48 кДа Myo1c виявився вірогідно нижчим порівняно з групою із низьким рівнем цього білка. Натомість, достовірних статистичних закономірностей між рівнем 48 кДа Myo1c та розподілом хворих на РС за статтю не було виявлено. Висновки. Myo1c відіграє важливу роль у патогенезі РС, а його 48 кДа ізоформа може бути раннім діагностичним маркером цього захворювання, а також кількісним індикатором процесу апоптозу активованих автореактивних клітин, що, зокрема, є важливим для оцінки ефективності хворобомодифікуючої терапії.
Ефективність, безпечність і переносимість комбінації електролітів та цитиколіну (Нейроцитин®) у пацієнтів із гострим ішемічним інсультом: перші результати дослідження
Authors: Titov I.I.
Published: April 2017

Актуальність. Гострий ішемічний інсульт є глобальною медичною проблемою, оскільки велика частина хворих помирає або стає інвалідами. У зв’язку з цим залишається актуальним пошук нових ефективних методів лікування даної патології. Ми ініціювали власне дослідження для оцінки одного з найбільш відомих церебропротекторів (цитиколін) у комбінації з електролітами (Нейроцитин®) при цьому виді гострих мозкових катастроф. Матеріали та методи. У відкрите рандомізоване контрольоване дослідження планується включити 55 пацієнтів обох статей віком від 25 до 75 років із діагнозом «гострий ішемічний інсульт». Контрольну групу складуть 25 пацієнтів зі стандартною терапією гострого ішемічного інсульту за наказом № 602 Міністерства охорони здоров’я України (без церебропротекторів). До основної групи буде включено 30 хворих із тією ж стандартною терапією + Нейроцитин® 100 мл 2 рази на добу протягом 14 днів. До головних критеріїв ефективності були віднесені: кількість балів за шкалою NIHSS, індексом Бартел і шкалою Ранкіна станом на 14-й день лікування; уміст нейронспецифічної єнолази (маркер ушкодження нейронів), величина біспектрального індексу (маркер електричної активності кори) станом на 14-й день лікування, показник церебральної оксиметрії (маркер оксигенації головного мозку) станом на 5-й день лікування; стан мозкової гемодинаміки за даними ультразвукової доплерографії судин головного мозку станом на момент виписки. Результати. На момент підготовки цієї статті в основну і контрольну групи дослідження було включено по 20 пацієнтів. Станом на 14-й день лікування зниження вмісту нейронспецифічної єнолази було в 2,73 рази більше в основній групі (зі включенням препарату Нейроцитин® (комбінація електролітів натрію, калію, кальцію, хлору, а також лактату та цитиколіну)) у порівнянні з контрольною і був близький до норми. Станом на 14-й день лікування зростання біспектрального індексу було на 64,9 % більше в основній групі порівняно з контрольною і його величина була близькою до норми. Станом на 5-й день лікування зростання показника церебральної оксиметрії було на 49,6 % більше в основній групі порівняно з контрольною і його величина досягала нормальних значень. У багатьох випадках покращання в групі з застосуванням препарату Нейроцитин® розвивалося в більш ранні терміни порівняно з терапією без церебропротектора. Висновки. Попередні результати проведеного нами дослідження свідчать про те, що включення препарату Нейроцитин® (комбінація електролітів натрію, калію, кальцію, хлору, а також лактату та цитиколіну) у схему лікування гострого ішемічного інсульту призводить до вірогідно більш швидкого зменшення пошкодження нейронів, відновлення електричної активності кори і оксигенації головного мозку порівняно з терапією без нейропротекції. У багатьох випадках ці ефекти спостерігаються в більш ранні терміни. Попередні результати дослідження вказують на доцільність включення Нейроцитину® в сучасні протоколи лікування гострого ішемічного інсульту.

Qualitative Interviews Exploring Palliative Care Perspectives of Latinos on Dialysis
Authors: Cervantes Lilia , Jones Jacqueline , Linas Stuart , Fischer Stacy
Published: April 2017

Background and objectives

Compared with non-Latino whites with advanced illness, Latinos are less likely to have an advance directive or to die with hospice services. To improve palliative care disparities, international ESRD guidelines call for increased research on culturally responsive communication of advance care planning (ACP). The objective of our study was to explore the preferences of Latino patients receiving dialysis regarding symptom management and ACP.

Design, setting, participants, & measurements

Qualitative study design using semistructured face-to-face interviews of 20 Latinos on hemodialysis between February and July of 2015. Data were analyzed using thematic analysis.

Results

Four themes were identified: Avoiding harms of medication (fear of addiction and damage to bodies, effective distractions, reliance on traditional remedies, fatalism: the sense that one’s illness is deserved punishment); barriers and facilitators to ACP: faith, family, and home (family group decision-making, family reluctance to have ACP conversations, flexible decision-making conversations at home with family, ACP conversations incorporating trust and linguistic congruency, family-first and faith-driven decisions); enhancing wellbeing day-to-day (supportive relationships, improved understanding of illness leads to adherence, recognizing new self-value, maintaining a positive outlook); and distressing aspects of living with their illness (dietary restriction is culturally isolating and challenging for families, logistic challenges and socioeconomic disadvantage compounded by health literacy and language barriers, required rapid adjustments to chronic illness, demanding dialysis schedule).

Conclusions

Latinos described unique cultural preferences such as avoidance of medications for symptom alleviation and a preference to have family group decision-making and ACP conversations at home. Understanding and integrating cultural values and preferences into palliative care offers the potential to improve disparities and achieve quality patient-centered care for Latinos with advanced illness.

Cross-level relationships between justice climate and organizational citizenship behavior: Perceived organizational support as mediator
Authors: Zhang Li , Qiu Yang , Teng Eryue
Published: April 2017

We investigated the mediating role of perceived organizational support in the cross-level relationships between procedural, interpersonal, and informational justice climate and organizational citizenship behavior. Hospital staff in China (N = 468) participated in this study.
Using hierarchical linear modeling, we found that procedural and interpersonal justice climate had a significantly positive effect on organizational citizenship behavior. Informational justice climate, however, did not have a significant effect on organizational citizenship behavior. In addition,
perceived organizational support mediated the effect of procedural and interpersonal justice climate on organizational citizenship behavior. Theoretical and practical implications of our findings are discussed in relation to justice climate and organizational citizenship behavior.
Effects of skepticism about corporate social responsibility advertising on consumer attitude
Authors: Yang Chao-Ming , Hsu Tzu-Fan
Published: April 2017

We adopted a 2 × 2 mixed experimental design to control for form of corporate social responsibility (CSR), advertising message claims (single message vs. multiple message), and levels of advertising skepticism (high vs. low), to elucidate how these influence advertising preferences
and advertising credibility. On the basis of data collected from 320 participants (152 men and 168 women), 4 significant findings were obtained: (a) The form of message claims in CSR advertisements affects advertising preference and advertising credibility, (b) levels of advertising skepticism
affect advertising preference and advertising credibility, (c) consumers with high advertising skepticism exhibit advertising skepticism toward CSR advertisements with single-message claims, (d) consumers with low advertising skepticism exhibit preference for CSR advertisements with multiple-message
claims. Our findings suggest that enterprises should plan advertisement content carefully when promoting their CSR activities because exaggerated or understated content triggers doubt in consumers' minds.

Published: April 2017

Our purpose in this study was to examine the relationship between presenteeism and the conscientiousness trait as an individual-level predictor of employee health and productivity. We used convenience sampling to recruit 168 Turkish health employees, who completed measures of conscientiousness
and presenteeism. The findings revealed that in a work outcomes context, the conscientiousness trait was positively related to the noncompletion of work dimension of presenteeism, the focus of which is on work outcomes. However, the relationship between the conscientiousness trait and the
distraction dimension of presenteeism was nonsignificant. Our findings have implications for managers and organizations, who should be proactive in taking preventative precautions to mitigate the possible negative effects of presenteeism behaviors.

A fejlesztéspolitikában ma a „smart” címkével minden vonzóbb, eladhatóbb, a kifejezés sokszor a ’környezetbarát’ vagy ’fenntartható’ szinonimájaként is használatos. A városfejlesztésben az utóbbi idők egyik legfelkapottabb paradigmája, globális szintű versengést indítva mind a városok, mind az érdekelt vállalatok között a kölcsönösen hasznosnak vélt előnyök reményében. A szerzők egyrészt annak jártak utána, miért éppen most virágzott fel a smart city mint fejlesztési paradigma, és milyen tényezők indukálták gyors előretörését. Másrészt a nemzetközi példák bemutatásán keresztül arra a kérdésre keresik a választ, milyen társadalmi hatásokkal járnak ezek a fejlesztések, milyen kihívásokkal kell szembenézni a smart city fejlesztések kapcsán, és vajon a jövőben a fejlesztési szereplők képesek lesznek-e tanulni hibáikból, és tudatosan tervezni a hatások összességével.

Do smart cities intensify social exclusion?

In development policy everything seems to be more attractive and marketable when labelled ‘smart’; the expression is often used even as a synonym for ‘environmentally-friendly’ or ‘sustainable’. Considering urban development projects, smart city development is one of the most popular paradigms, triggering global competition between cities as well as the interested companies, both expecting mutual benefits from the co-operation. The article, on the one hand, tries to reveal, why the smart city paradigm has now started to thrive, and what factors played a part in its rapid development. On the other hand, through the presentation of international practices, the authors intend to answer what social impacts these developments have had, what challenges have the smart city developments met, and whether in the future the actors could learn from their mistakes and consciously take into account the complexity of impacts.

The icon of the Theotokos from the Church of St. Nicholas (Rajko’s Church) and the question of painting workshops in medieval Prizren
Authors: Vojvodic Dragan
Published: April 2017

Based on stylistic and paleographical analysis, it can be safely concluded
that the icon of the Theotokos from the Church of St. Nicholas (Rajko?s
Church) in Prizren was not created in the 14th century as previously
believed. It was painted in the last third of the 16th century by an icon
painter close to the circle of Serbian painters formed in Pec. The suggestion
of stylistic ties between this icon and the first fresco layer at the Church
of the Holy Savior in Prizren and the wall paintings in the Church of St.
Nicholas (the Tutic Church) is not acceptable. Furthermore, comparison of
wall paintings in these and other contemporaneous churches in the area of
Prizren, as well as the local icon paintings, does not substantiate the
suggestion that an urban painting workshop operated in 14th-century Prizren.
Early Glycemic Control and Magnitude of HbA1c Reduction Predict Cardiovascular Events and Mortality: Population-Based Cohort Study of 24,752 Metformin Initiators
Authors: Svensson Elisabeth , Baggesen Lisbeth M. , Johnsen Søren P. , Pedersen Lars , Nørrelund Helene , Buhl Esben S. , Haase Christiane L. , Thomsen Reimar W.
Published: April 2017

OBJECTIVE

We investigated the association of early achieved HbA1c level and magnitude of HbA1c reduction with subsequent risk of cardiovascular events or death in patients with type 2 diabetes who initiate metformin.

RESEARCH DESIGN AND METHODS

This was a population-based cohort study including all metformin initiators with HbA1c tests in Northern Denmark, 2000–2012. Six months after metformin initiation, we classified patients by HbA1c achieved (<6.5% or higher) and by magnitude of HbA1c change from the pretreatment baseline. We used Cox regression to examine subsequent rates of acute myocardial infarction, stroke, or death, controlling for baseline HbA1c and other confounding factors.

RESULTS

We included 24,752 metformin initiators (median age 62.5 years, 55% males) with a median follow-up of 2.6 years. The risk of a combined outcome event gradually increased with rising levels of HbA1c achieved compared with a target HbA1c of <6.5%: adjusted hazard ratio (HR) 1.18 (95% CI 1.07–1.30) for 6.5–6.99%, HR 1.23 (1.09–1.40) for 7.0–7.49%, HR 1.34 (1.14–1.57) for 7.5–7.99%, and HR 1.59 (1.37–1.84) for ≥8%. Results were consistent for individual outcome events and robust by age-group and other patient characteristics. A large absolute HbA1c reduction from baseline also predicted outcome: adjusted HR 0.80 (0.65–0.97) for Δ = −4, HR 0.98 (0.80–1.20) for Δ = −3, HR 0.92 (0.78–1.08) for Δ = −2, and HR 0.99 (0.89–1.10) for Δ = −1 compared with no HbA1c change (Δ = 0).

CONCLUSIONS

A large initial HbA1c reduction and achievement of low HbA1c levels within 6 months after metformin initiation are associated with a lower risk of cardiovascular events and death in patients with type 2 diabetes.
Association of Glycemic Variability in Type 1 Diabetes With Progression of Microvascular Outcomes in the Diabetes Control and Complications Trial
Authors: Lachin John M. , Bebu Ionut , Bergenstal Richard M. , Pop-Busui Rodica , Service F. John , Zinman Bernard , Nathan David M. ,   for the DCCT/EDIC Research Group
Published: April 2017

OBJECTIVE

The Diabetes Control and Complications Trial (DCCT) demonstrated the beneficial effects of intensive versus conventional therapy on the development and progression of microvascular complications of type 1 diabetes. These beneficial effects were almost completely explained by the difference between groups in the levels of HbA1c, which in turn were associated with the risk of these complications. We assessed the association of glucose variability within and between quarterly 7-point glucose profiles with the development and progression of retinopathy, nephropathy, and cardiovascular autonomic neuropathy during the DCCT.

RESEARCH DESIGN AND METHODS

Measures of variability included the within-day and updated mean (over time) of the SD, mean amplitude of glycemic excursions (MAGE), and M-value, and the longitudinal within-day, between-day, and total variances. Imputation methods filled in the 16.3% of expected glucose values that were missing.

RESULTS

Cox proportional hazards models assessed the association of each measure of glycemic variation, as a time-dependent covariate, with the risk of retinopathy and nephropathy, and a longitudinal logistic regression model did likewise for cardiovascular autonomic neuropathy. Adjusted for mean blood glucose, no measure of within-day variability was associated with any outcome. Only the longitudinal mean M-value (over time) was significantly associated with microalbuminuria when adjusted for the longitudinal mean blood glucose and corrected for multiple tests using the Holm procedure.

CONCLUSIONS

Overall, within-day glycemic variability, as determined from quarterly glucose profiles, does not play an apparent role in the development of microvascular complications beyond the influence of the mean glucose.
A Perspective: Gun-Related Fatalities and Manner of Death
Authors: Hanzlick Randy L.
Published: April 2017

Because this issue of Academic Forensic Pathology is dedicated to firearms related topics, the author was invited to provide a perspective on manner of death classification in firearms-involved deaths. This article discusses cases which are routinely encountered, as well as a selected group of more rare and more controversial cases regarding manner of death classification. The experience, knowledge, personal philosophies, and even conscious or unconscious biases of individual certifiers of death vary and can have impact on manner of death certification. Further, in many cases, there is no right or wrong answer and there is plenty of room for disagreement and debate. For these reasons, and with a goal of national consistency in manner of death classification, the author recommends that the National Association of Medical Examiners implement a task force to make recommendations as to how manner of death should be classified in specific types of firearms-related deaths. To date, some guidelines have been published but they do not carry the weight of specific and official recommendations. There must always be room for certifier discretion, but such discretion could be used in the context of a set of formal recommendations as a baseline, so that variances can be explained and manner of death certifications cannot be viewed as arbitrary and/or capricious. This article includes the author's viewpoints concerning manner of death in selected cases.
Genetic Counselors: An Important Resource for Families following a Young Sudden Cardiac Death
Authors: MacLeod Heather , Demo Erin , Honeywell Christina , Rutberg Julie
Published: April 2017

Sudden cardiac death is a tragic result of a number of cardiovascular diseases. While the majority of sudden cardiac death cases are in older individuals with coronary artery disease, victims also include younger people (those less than 40 years old). At least 40% of cases of young sudden death are attributable to genetic causes, including diagnoses such as long QT syndrome and hypertrophic cardiomyopathy. In 50% of young sudden death cases, there are no warning signs or family history of sudden death. These young sudden deaths are a tragedy for families and in many cases are devastating for communities as well. Awareness is spreading among medical examiners and cardiologists on how to assess and treat these families but few healthcare providers see cases routinely. The combination of an unexpected death and the burden of potentially having a genetic disease themselves leaves family members in a vulnerable and often overwhelming position. Genetic counselors, particularly those who specialize in cardiovascular disease, are uniquely qualified to help surviving family members navigate the medical and psychosocial issues present in these cases.
A Unique Case of Attempted Two Gun Suicide with One Firearm Discharge and Two Muzzle Imprints
Authors: Poulos Christopher K. , Thorne Todd A.
Published: April 2017

Two gun suicides are rare and many authors regard them a special form of “planned complex suicide.” As with all multi-gunshot suicides, two gun suicides may initially lead to an increased suspicion of a homicide. In this article, the authors describe the case of an attempted two gun suicide where a 38-year-old male used two .45 caliber weapons to shoot himself, but only one discharged. Both firearms left muzzle imprints, despite only one having been fired. This case not only represents a rare form of suicide, but the muzzle imprint from the non-fired weapon provides an illustration of the mechanism of muzzle imprint formation.
Addressing the Burden of Gun Violence
Authors: Hargarten Stephen W. , Christiansen Ann , Jentzen Jeffrey M.
Published: April 2017

Gun violence in the U.S. is a significant public health burden, accounting for over 30,000 deaths and an estimated 73,000 injures each year. Like other disease burdens with complex interactions between the host (individuals), agents (firearms) and the environment, epidemiological principles can identify patterns in the determinants and distribution of firearm injuries to develop, implement and evaluate evidence-based interventions (programs, policies, technologies). The National Violent Death Reporting System (NVDRS) was formed in 2002 with funding from the Centers for Disease Control and Prevention to link information on violent deaths from medical examiners and coroners to data on circumstances and weapons from law enforcement and crime laboratories. Involvement of forensic pathologists, medical examiners and coroners is critically important for a complete National Violent Death Reporting System and vital for the systematic collection, analysis, and dissemination of data on all violent deaths in the United States.
Ethics and Research on Bodies in the Jurisdiction of Coroners or Medical Examiners
Authors: Cordner Stephen , Leahy Fiona
Published: April 2017

An autopsy is a significant event and should not be undertaken for simply narrow purposes. Forensic pathology institutions, whether in coronial or medical examiner jurisdictions, should be actively engaged in research, either directly or by facilitating access to bodies, tissues and data. The challenge, assuming that resources are available, is to do this lawfully, ethically, and in accordance with community expectations. Failure in the challenge will be wrong and cause damage to the reputation of the institution. The risks associated with such research therefore need to be managed. An approach which is transparent and based on respect for the deceased and consent for the activity, while no guarantee of success, is likely to engender community confidence in the activity and in those undertaking it.
ENERGY SAVING TECHNOLOGIES OF PORT FACILITIES ON THE BASIS OF GEO-THERMAL HEAT PUMPS
Authors: Saprykina Nadejda Yuryevna , Yakovlev Pavel Victorovich
Published: April 2017

Energy-saving technologies of port facilities and shipyards on the basis of geothermal heat pumps are a very promising direction. The features of offshore facilities are their presence in the zone of influence of seepage flow of ground water, significantly complicating the introduction of energysaving geothermal systems. The results of mathematical modeling of temperature field of soil mass, generated during the operation of the vertical ground heat exchanger of geothermal heat pump over 5 years are presented. The developed method is based on the equation of unsteady heat conduction and setting of boundary conditions for the different operating modes of the heat pump. The results of the temperature field changes were suggested in three modes of operation of geothermal plants: without changing the direction of heat flow, with a change in the direction of heat flow (regeneration) and in the condition of complicated influence of filtration flow of groundwater. The studies were conducted in order to build computational models that are adequate to real physical processes. The method of similarity theory is used to generalize the results.
DETERMINATION OF DIESEL COMPRESSION RATIO BY RESULTS BY THE PROCESS INDEXING
Authors: Yeryganov Alexey Valerievich , Varbanets Roman Anatolievich
Published: April 2017

The calculation method for determining the volume of the compression chamber and the compression ratio in the cylinder is proposed according to the diesel’s indicator diagram. The point of the compression curve is used where rate of pressure rise is maximum. At this point, the second derivative of the pressure curve along the crank angle is zero. The equation for the second derivative of the compression curve in the polytropic form was fixed. In solving this equation the polytropic index has been reduced, which enabled to derive an expression for the volume of a cylinder at the specified point in the analytical form. As a result, from the known geometrical parameters of the cylinder and the data taken from the diesel’s indicator diagram, it is possible to determine the diesel compression ratio with engineering precision, which is especially important for modern low-speed diesel engines, such as MAN, Wartsila, the documentation of which doesn’t specify this setting.

Authors: Sergeev Konstantin Olegovich , Pankratov Andrew Adol'fovich
Published: April 2017

The method of determining the technical condition of the injector of high-speed diesel using the method of vibration control on the injector body is considered. Vibration signal is measured by the accelerometer and is filtered by 1/3 - octave filter with a center frequency of 63 kHz. The measurements were performed at idle, 20%, 33%, 66% and 100% of rated power, as well as on the nominal power with an artificially introduced defect of the injector - spring breakage. The temporal realization of the signal is used for diagnosis. The conclusions about the nature of the change in the temporal realization of vibration signal depending on the power state and the presence of faults have been made. The possibility of determining of the cyclic supply and cylinder output using the vibration signal was estimated. The direction of further research to improve the accuracy of diagnosis has been proposed.

Published: April 2017

For independent supply of electric energy of objects of the various purposes consid-erably removed from the industrial energy networks the perspective direction is the application and the use of a solar energy by means of its transformation to photo-electric batteries. The purpose of the present research is to improve the efficiency of photo-electric elements due to the application of flat concentrators, a rational choice of design and a relative positioning of an adapting and reflecting surface at the optimum area of penetration of solar beams. The suggested constructive solutions will allow reducing weight and sizing characteristics of solar batteries considerably, applying on sea platforms, beacons, ship and coastal objects and the complexes having the limited working areas. The given goal is achieved by solving the following problems: choose qualitative, not expensive and technological photoelements in manufacturing; create the maximal illumination of photoelement by solar energy, defining the maximum coefficient of solar radiation concentration on adapting surface; define rational interposition of photomodules in flat mirrors, and also find optimum angles of mirrors’ disclosure. The survey analysis of existing ways of manufacturing and usage of photo-electric elements in solar batteries has been conducted: polycrystalline silicon, monocrystal silicon, amorphous silicon, photo elements on the basis of telluride of cadmium, etc. The research of the photo elements, having adapting surface in the form of a correct triangle with the side " a " established in center of two flat mirrors with a corner of disclosing Q , has been carried out. Mathematical expressions and the graphic dependences defining an overall performance of the concentrator through optical factor of concentration have been received. The analytical researches show, that parameters of concentrators are effective at W = 4 a (a surface of an input of solar beams), Q = 45-50°, while power efficiency is increased by 40%, and the nominal value is reduced by 25%.

Dari penelitian ini dapat disimpulkan bahwa perbedaan yang ada antara novel dan film AAC bukan sebatas karena perbedaan sistem sastra dan sistem film, tetapi perbedaan yang disengaja oleh tim produksi film dengan maksud tertentu. Dari pengayaan dan berdasar pada fakta yang diungkap, peneliti menyimpulkan bahwa film AAC lebih menekankan pada persoalan poligami, ini terlihat dengan banyaknya penambahan adegan di dalam film yang menampilkan kehidupan poligami yang tidak ada di novel, sementara novel AAC lebih berisi. penggambaran perjuangan seorang mahasiswa Indonesia yang kuliah di Mesir beserta perjalanan kisah asmaranya.

Abstract

Adaptation process from novel to film is called ecranization. The differences often show up in the process of ecranization all this time is more regularly because of the difference of art

system (in this case novel) and the film system. Technical things as media or novel which consist of words and language, meanwhile film main media is audio visual (sow1d and picture) becomes a common thing if between novel and film become different. In the case of AAC's novel and film, the difference is not only because of that technical problem, but this is an intentional difference. From this research can be concluded that difference among AAC's novel and film is not one bounds because an system difference and film system, but intentional difference by film production team for the specific purposes. From enrichment and based on fact that revealing, researcher concludes that AAC's film more emphasizes on polygamy problem, this appears on many added scenes in film that feature polygamy life that is not tell in the novel, while AAC'S novel more consist of the struggle of an Indonesian college student that study at Egypt there with his love story.

Abstract

Madurese traditional songs and the traditional songs' lyrics are two of Madurese cultures. But, because Madurese people lack understanding of the Madurese Lyrics values, this makes the lyrics meaningless. Because of that, Madurese pay little attentions to the lyrics and consider them as ordinary cultural works which play no role towards their society. In fact, when they study further the values behind the lyrics, they will realize that, actually, the lyrics contain a lot of wisdoms and are able to give them a picture that shows them who they really are. This picture can become a form of guidance in their society. This article informs the reader the truth portrait about the real Madurese characters that are reflected from Madurese traditional songs' lyrics.

ГЕОХИМИЯ МАРГАНЦА В ПРОЦЕССАХ ГИПЕРГЕНЕЗА: ОБЗОР
Authors: Юдович Я.Э. , Кетрис М.П.
Published: April 2017

Главной чертой гипергенной геохимии марганца является процесс окисления его кислородом: Mn(II) ⇒ Mn(III, IV) с формированием минералов манганатов общей формулы MnOx (x более 1, менее или равно 2), способных поглощать значительные количества катионов (K+, Ba2+, Со2+, Ni2+, Cu2+ и др.). Вследствие кинетических ограничений абиогенное формирование манганатов протекает крайне медленно, поэтому важнейшее, включая и рудообразующее, значение имеет биогенное окисление Mn(II) аэробной гетеро- и миксотрофной микрофлорой. Продуктом субаэрального окисления Mn(II) являются коры выветривания двух климатических типов – кислые гумидные (с мобилизацией и частичным выносом Mn) и щелочные аридные (с накоплением Mn), но итоговый минеральный парагенезис сильно зависит от состава первичного субстрата и Eh–pH параметров среды. Рассмотрен ряд эмпирических закономерностей окисления Mn(II) и формирования кор выветривания, выявленных как на природных объектах (в том числе и на Mn месторождениях Тимано-Уральского региона), так и в лабораторных экспериментах.
БИОРАЗНООБРАЗИЕ И АРЕАЛЫ ОСНОВНЫХ ТОКСИНОПРОДУЦИРУЮЩИХ ГРИБОВ РОДА FUSARIUM

Published: April 2017

Род Fusarium включает виды грибов, разнообразные по типу питания (сапротрофы, некротрофы, биотрофные патогены, эндофиты) и способности образовывать вторичные метаболиты, в том числе высокотоксичные. Среди грибов рода Fusarium выявлены виды с широкой экологической валентностью, встречающиеся повсеместно (например, Fusarium poae и F. sporotrichioides), и виды, требовательные по отношению к отдельным факторам окружающей среды, существующие в виде более или менее локальных популяций (например, F. graminearum, F. culmorum, F. cerealis). Способность грибов приспосабливаться к различным условиям среды связана с их генетической пластичностью и метаболическим разнообразием. Системный подход к изучению видовых комплексов характеризует эколого-биохимические аспекты существования грибов Fusarium (широта ареалов, приуроченность к определенным климатическим условиям, трофическая специализация), а также позволяет выявлять процессы видообразования и генетической адаптации. Недавно описаны новые для науки виды грибов (F. ussurianum и F. sibiricum) на дальневосточной территории России и в Сибири, что не исключает их выявления в других регионах. Приведен обзор распространения наиболее опасных видов грибов рода Fusarium, способных продуцировать высокотоксичные трихотеценовые метаболиты. Знание ареалов токсинопродуцирующих видов грибов позволяет прогнозировать и предотвращать загрязнение микотоксинами урожая зерна и продуктов его переработки и, тем самым, снизить риск заболеваний человека и животных.

Разработка концепции развития охотничьего хозяйства на территории Ленинградской области на десятилетний период невозможна без учета исторического опыта и результатов громадного социально-экономического эксперимента, поставленного самой историей нашей страны. Экономические потрясения, различные социальные проявления, политические приоритеты, законодательная нестабильность определяли состояние охотничьего хозяйства России в последние 20 лет. Поэтому в настоящий период важно дать объективную оценку состояния в этой сфере природопользования, показать необходимость принимать за основу биологические принципы при определении приоритетов и основных направлений государственной политики во всех сферах деятельности, а также учитывать их при долгосрочном социально-экономическом планировании развития как субъектов Российской Федерации, так и страны в целом. В этой работе предпринята попытка осветить вопросы общей теории охоты, виды и методы практической деятельности, дать исторический обзор охотничьего хозяйства Ленинградской области за последние 30 лет и выработать рекомендации по улучшению состояния в этой сфере в Ленинградской области на десятилетнюю перспективу.
Comparison of Endoscopic Findings with Gastroesophageal Reflux Disease Questionnaires (GerdQ) and Reflux Disease Questionnaire (RDQ) for Gastroesophageal Reflux Disease in Medan
Authors: Siregar Gontar Alamsyah , Halim Sahat , Sitepu Ricky Rivalino
Published: April 2017

Background: There are many questionnaires that have been developed to diagnose gastroesophageal reflux disease (GERD), i.e. reflux disease questionnaire (RDQ), and the recently developed, gastroesophageal reflux disease questionnaires (GerdQ). In this study, we tried to compare GerdQ and RDQ in terms of sensitivity and specificity to diagnose GERD and its relationship with endoscopic findings.Method: This study was a cross sectional analytical study. Subsequently, all the subjects were evaluated using the GerdQ and RDQ, then underwent esophagogastroduodenoscopy examination. The severity of endoscopically observed reflux esophagitis was graded with the Los Angeles classiﬁcation. All endoscopy was performed by well-trained doctor.Results: A total of 85 patients were examined, 34 (40%) patients had reflux esophagitis at endoscopy examination, including 15 (44.1%) cases of grade A, 11 (32.3%) cases of grade B, 4 (11.8%) cases of grade C, and 4 (11.8%) cases of grade D. Analysis study using sensitivity, specificity, and receiver operating characteristic (ROC) test showed that GerdQ had sensitivity (49%), specificity (91%), and an area under the ROC of 0.701 (p value = 0.002). RDQ had sensitivity (24%), specificity (91%), and an area under the ROC of 0.574 (p value = 0.253). Taking 11 as the cut off point for GerdQ, a maximal sensitivity of 73.5%, specificity of 82.4%, and an area under the ROC of 0.779 was achieved.Conclusion: GerdQ and RDQ can be used to help diagnose GERD, but GerdQ is more superior than RDQ in diagnosing GERD. A multi-center study with larger samples is needed to determine the best GerdQ’s cut off point in Indonesia.

Gastroesophageal reflux disease (GERD) was a damage in mucosal layer caused by gastric acid reflux. GERD was found about 10-20% in Western Countries and less in Asia, about 2,6-6,7%. Among different type of GERD, refractory GERD was a problem found in daily clinical practice. This terminology was used in patients with regurgitation and heartburn symptoms which is not responsive to 8 weeks proton pump inhibitor (PPI) therapy. There were several mechanisms underlying the etiology and pathophysiology of refractory GERD. In general, refractory GERD diagnosis was based on clinical findings, objective endoscopic examination, ambulatory reflux monitoring, and response to antiacid-secretion therapy. Reevaluation of patients compliance should be the first step in refractory GERD management. A further treatment strategies could be started, consist of medical and surgical therapies. A basic clinical knowledge of refractory GERD would help clinician in deciding the best approach for diagnosis and therapy.

Published: April 2017

Iatrogenic bile duct stricture is the most common causes of benign bile duct stricture. Several studies reported that approximately 80% of benign strictures occur following injury during a cholecystectomy. Strictures of the biliary tract have a broad spectrum of manifestations, ranging from mild elevation of liver enzymes to life-threatening infections such as cholangitis, liver abscess, and biliary cirrhosis. Moreover, due to its indolent course with subtle clinical manifestations, diagnosis is often delayed and most patients present with a protracted, complicated course. We reported a case of 26 years old female with recurrent cholangitis due to iatrogenic bile duct stricture. Biliary drainage through endoscopic approach followed by surgical procedure was selected as strategic management for the patient.
