Abstract
In this work, the structure properties and mass attenuation coefficient of MgO nanoparticles were studied before and after gamma irradiation. The as-synthesized samples of MgO nanoparticles by sol–gel method were analyzed by XRD which suggested the double phase; cubic and hexagonal structures of the material. Crystal defects produced in the cubic and hexagonal lattice were studied before and after exposure to 20 kGy gamma irradiation in order to investigate the changes in the structure properties and mass attenuation coefficients of MgO nanoparticles. XRD data of gamma-irradiated and non-irradiated MgO nanoparticles show that the crystal size of MgO nanoparticles increases after radiation exposure. SEM images after irradiation indicated significant changes in the morphology. The UV-Visible absorption spectra of the nanoparticles were taken and the results of optical band gap of the MgO nanoparticles before and after irradiation show that the value of band gap has changed slightly due to gamma irradiation. The results of comparing experimental values of mass attenuation coefficient for non-irradiated MgO nanoparticles with theoretical values of mass attenuation coefficient for MgO microparticles calculated using the NIST XCOM show that the mass attenuation coefficient not only depends on the effective atomic number but also depends on the size of the particles. Also, it is observed that the mass attenuation coefficient of MgO nanoparticles decreases after the irradiation which shows that by increasing the size of the nanoparticles, the mass attenuation coefficient decreases. It could be because the cross-section of photon interaction with materials depends on the surface to volume ratio of nanoparticles. The experimental results also show that the linear and mass attenuation coefficient of MgO nanoparticles decrease with increasing the photon energy.
Unités linguistiques et formes textuelles
Authors: Rastier François 
Published: May 2018

Résumé La tradition scolaire a élaboré une conception de l’unité conforme avec l’hypothèse d’un parallélisme logico-grammatical. Elle s’avère discutable, tant au palier du mot qu’à celui de la phrase et plus encore au palier du texte. En revanche, des grandeurs comme les thèmes ou des fonctions narratives peuvent être décrites comme des formes sémantiques et expressives, susceptibles d’être représentées par des groupements structurés de traits. Au fil du texte, ces formes sont le support demétamorphismes, transformations récurrentes qui déterminent son orientation. Les formes textuelles se détachent sur des fonds expressifs et sémantiques (les isotopies). Au cours du texte, les fonds eux-mêmes peuvent évoluer par destranspositions. La dynamique du parcours textuel comprend en outre des dissolutions de formes par diffusion dans les fonds, et des sommations synthétiques qui construisent des formes à partir d’éléments des fonds. Il faut donc reconsidérer la question des unités et celle des règles linguistiques à la lumière du texte, en reconnaissant la détermination du global par le local et en tenant compte également de l’interprétation des sorties logicielles en sémantique de corpus.
Die älteste tschechische Übersetzung von Märchen aus Tausendundeine Nacht
Authors: Berger Tilman 
Published: May 2018

Summary
This paper deals with a manuscript from the library of the Regional Museum in Chrudim (East Bohemia) which contains a Czech translation of some of the tales of ‘One Thousand and One Nights’. The manuscript was written at the end of the 18th century in a rather peculiar orthography and belongs to a group of manuscripts which were evidently written by a single person, the painter Josef Ceregetti (1722–1779). The language used in these manuscripts is the literary Czech of that time, with some influence from spoken language. By comparison of the French text of Galland and two contemporary German translations with the Czech text I show that the author seems to have been working with the German translation from the year 1730. The Czech translation was probably intended for a local circle of intellectuals, mainly clerics, and never reached a broader public.

Summary
The so-called Gliedervergottung section of BD 42 displays close textual and iconographic features in two Eighteenth Dynasty sources: the burial chamber of the tomb of Djehuty (TT 11) and the papyrus of Baksu (Hanover KM 1970.37). Both sources will be presented, transcribed, and compared to highlight their derivation from the same master copy. Finally, some thoughts on what dublettes can tell us about Book of the Dead Vorlagen and scribal activities will be offered.
The Misnomer of Nomarchs
Authors: Tomkins Jessica 
Published: May 2018

Summary
The terms “nome” and “nomarch” are widely used in Egyptology as the basic framework for discussing and understanding provincial administration of the Old to Middle Kingdoms, even though these are much later Greek terms. This article traces the origins of these words and highlights the problems encountered by applying these later terms to an earlier period of Egyptian history, and how they have obscured our understanding of the mechanics of provincial administration of the Old to Middle Kingdoms.

Abstract
Two new alkylresorcinol derivatives, namely ochocinone A and ochocinone B (1, 2), as well as a known alkylresorcinol oleiferinone (3) were isolated from the methanol extract of the leaves of Scyphocephalium ochocoa. The structures of these compounds were established by detailed spectroscopic analysis and by comparison with the spectral data of related known compounds. Compounds 1–3 showed significant immunomodulatory activity and cytotoxic effect on the mammary carcinoma MCF-7 cell line.
Explaining the relation between pathological gambling and depression: Rumination as an underlying common cause
Authors: Krause Kristian , Bischof Anja , Lewin Silvia , Guertler Diana , Rumpf Hans-Jürgen , John Ulrich , Meyer Christian 
Published: May 2018

Background and aims
Symptoms of pathological gambling (SPG) and depression often co-occur. The nature of this relationship remains unclear. Rumination, which is well known to be associated with depression, might act as a common underlying factor explaining the frequent co-occurrence of both conditions. The aim of this study is to analyze associations between the rumination subfactors brooding and reflection and SPG.

Methods
Participants aged 14–64 years were recruited within an epidemiological study on pathological gambling in Germany. Cross-sectional data of 506 (80.4% male) individuals with a history of gambling problems were analyzed. The assessment included a standardized clinical interview. To examine the effects of rumination across different levels of problem gambling severity, sequential quantile regression was used to analyze the association between the rumination subfactors and SPG.

Results
Brooding (p = .005) was positively associated with the severity of problem gambling after adjusting for reflection, depressive symptoms, and sociodemographic variables. Along the distribution of problem gambling severity, findings hold for all but the lowest severity level. Reflection (p = .347) was not associated with the severity of problem gambling at the median. Along the distribution of problem gambling severity, there was an inverse association at only one quantile.

Discussion and conclusions
Brooding might be important in the development and maintenance of problem gambling. With its relations to depression and problem gambling, it might be crucial when it comes to explaining the high comorbidity rates between SPG and depression. The role of reflection in SPG remains inconclusive.

Abstract: Introduction and aim: The worldwide incidence of differentiated thyroid cancer (DTC) has markedly increased during the last few decades. According to the international guidelines, principles of DTC management are in transformation. The aim of our work was to evaluate patients’ current likelihood of recovery. Method: Data of 380 patients treated between 1/Jan/2005 and 1/May/2016 at the PTE KK Ist Department of Internal Medicine were retrospectively analyzed. Female/male ratio was 306/74. Median age at diagnosis was 46 years (13–86 years), while median follow-up time was 55 months (0–144 months). Response to therapy was evaluable in 337 patients. Statistical analysis was done using SPSS (version 22.0). Results: Based on the prevalence of papillary (PTC) and follicular (FTC) carcinomas (79/21%), moderate iodine deficiency has to be considered in this region. PTC patients were significantly younger and were diagnosed in earlier tumor stage. The ratio of lymph node and distant metastases was 35%/4% in PTC and 15%/14% in FTC. Radioiodine treatment was performed in a total of 542 times. 264 patients with PTC were followed up. 59% of patients were tumor-free, in 20% uncertain response, in 7% incomplete biochemical response, in 14% incomplete structural response were diagnosed and 6 patients died. Patients with FTC (n = 73) were tumor-free in 59%, uncertain response was found in 10%, incomplete structural response was diagnosed in 31%, while 10% of the patients died. Conclusions: In summary, although DTC has a favorable prognosis, in 31% of FTC patients and in 14% of PTC patients, tumor-free status was not achieved. During the median 55-month follow-up period, the disease-specific mortality was 10% in FTC and 2% in PTC. Orv Hetil. 2018; 159(22): 878–887.

Abstract: Introduction and aim: To present two cases of placoid chorioretinopathy (ocular syphilis and ocular tuberculosis) and underline the importance of differential diagnosis. Method: Two young female patients presented with unilateral loss of vision. Fundus examination showed yellowish placoid lesions in the posterior pole in both cases. Results: Performing fluorescein angiography and laboratory investigations, ocular syphilis was diagnosed in our first case and intraocular tuberculosis was diagnosed in our second case. Conclusion: It is important to determine the etiology of the placoid choriaretinopathies due to the different prognosis and therapy and the exclusion of systemic diseases. A comprehensive evaluation of these patients is inevitable for the correct diagnosis and appropriate management. Orv Hetil. 2018; 159(22): 863–869.

Abstract: Low output syndrome significantly increases morbidity and mortality of cardiac surgery and lengthens the durations of intensive care unit and hospital stays. Its treatment by catecholamines can lead to undesirable systemic and cardiac complications. Levosimendan is a calcium sensitiser and adenosine triphosphate (ATP)-sensitive potassium channel (IK,ATP) opener agent. Due to these effects, it improves myocardium performance, does not influence adversely the balance between O2 supply and demand, and possesses cardioprotective and organ protective properties as well. Based on the scientific literature and experts’ opinions, a European recommendation was published on the perioperative use of levosimendan in cardiac surgery in 2015. Along this line, and also taking into consideration cardiac surgeon, anaesthesiologist and cardiologist representatives of the seven Hungarian heart centres and the children heart centre, the Hungarian recommendation has been formulated that is based on two pillars: literature evidence and Hungarian expert opinions. The reviewed fields are: coronary and valvular surgery, assist device implantation, heart transplantation both in adult and pediatric cardiologic practice. Orv Hetil. 2018; 159(22): 870–877.

Mathematical methods for quantification and comparison of dissolution testing data
Authors: Vranić Edina , Mehmedagić Aida , Hadžović Sabira 
Published: May 2018

In recent years, drug release/dissolution from solid dosage forms has been the subject of intense and profitable scientific developments. Whenever a new solid dosage form is developed or produced, it is necessary to ensure that drug dissolutionoccurs in an appropriate manner. The pharmaceutical industry and the registration authorities do focus, nowadays, on drug dissolution studies. The quantitative analysis of the values obtained in dissolution/release tests is easier when mathematicalformulas that express the dissolution results as a function of some of the dosage forms characteristics are used. This work discusses the analysis of data obtained for dissolution profiles under different media pH conditions using mathematical methodsof analysis described by Moore and Flanner. These authors have described difference factor (f1) and similarity factor (f2), which can be used to characterise drug dissolution/release profiles. In this work we have used these formulas for evaluation of dissolution profiles of the conventional tablets in different pH of dissolution medium (range of physiological variations).
Frequency of rh phenotypes in relation to the outcome of pregnancy in the two groups of pregnant women
Authors: Redžić Amira , Begić Fatima 
Published: May 2018

Lethal and sublethal genetical factors, including Rh factor, represent endogenous risk factors of the pregnancy outcome. These factors are most frequently inherited in recessive way and they often lead to the negative outcome of pregnancies. They represent pregnancy (a prirori) risk of various degrees. Inheritance of Rh system blood groups is linked to chromosome 1 and it could be explained by two alternative theories; molecular Rh system genetics has not yet been completely explained. The first formal-genetic theory postulates three closely linked gene sites (loci C, D and E) while the second theory has a monogenic character (one locus with several allele genes). Data on 755 pregnancies, which were (for various reasons) estimated as increased risk pregnancies, were registered at Gynaecology Clinic, Clinical Centre of University of Sarajevo, during the period from 1989 to 1992. These data were collected from pregnant women who, according to the certain indications from their familiar and personal anamnesis, demanded genetic consultations. The result of investigation of the basic Rh system phenotype distribution shows no statistically significant difference between monitored pregnant women. This result is assumed as valid for both pregnant women and their partners. The same result is suggesting that the observed increased risk pregnancy samples do not significantly differ from the previously studied population samples. Therefore, it has been concluded that Rh factor is not closely related to the increased risk of individual pregnancy outcomes, that is, it does not have relevant influence on the observed reproduction parameters. This result is very interesting and deserves particular medical attention and further evaluation in the future, particularly considering known immunological phenomena resulting from relations between reproduction partners belonging to the basic Rh system phenotypes.

he main active component of preparation HEPALIP FORTE is EPL--essential phospholipids. Their chemical structure corresponds to that of endogen phospholipids, but they have functional superiority because of the content of unsaturated fatty acids. Essential phospholipids in combination with the vitamins have been used in the treatment of liver diseases, dyslipoproteinaemias and intoxications with consequent liver failure. Acute toxicity study on HEPALIP FORTE was performed on Wistar rats. The main aim of toxicology studies for the drug registration process is evaluation of the toxic potential and risks of human exposition to the substance (Gelbke et al., 1999). Acute toxicity is an orientation point of the test substance toxicity and represents a starting test for the toxicological evaluation. Study included one oral dose of the substance, applied with oesophageal intubations. There were three dose-levels: 300, 500 and 1000 mg/kg. No lethality was recorded and statistical analysis of body weight variations failed to show any significant difference between the groups. Reversible tremor was more frequently recorded in females and was not present in control animals. After the planed sacrifice, no changes related to the test substance were recorded. We noticed a statistically significant difference in the liver weights between males of 3M and 2M groups in comparison to the control. Similar (not significant) tendency was noticed in females. Significant differences in organ weights might be suggestive of a toxic effect that experimental animal managed to recover from in partial manner. The histopathological analysis detected no changes in the structure and morphology of liver parenchyma.

Published: May 2018

Brunkow exercises starting with dynamic contraction of hands and feet with fixed point on the wrist or/and heal. Dynamic contraction from the beginning, transferring through kinetic chain, leads to isometric contraction of the group of muscles, which has to be included in the exercise. Starting positions determine the group of muscles to be trained. The purpose of this study is to investigate influence of Brunkow exercises on spinal motion improvement and pain relief and to evaluate use of Brunkow exercises, as a routine method for lower back pain in Physical Medicine and Rehabilitation Centres. Thirty-four patients with symptoms of low back pain were included in study. Patients received a mean of 14.9 treatments with standard deviation of 8.96. All patients were assessed before and after the treatment for spinal mobility and flexibility as well as pain intensity. All parameters for spinal movements showed statistically significant improvement in patients with low back pain who practiced Brunkow exercise program at the end of treatment in relations to pre-treatment values, with significant difference of p<0.01 for all motions. Pain was reduced on VAS for X=1.,7 with S.D. 1.97. Difference Test was t=6.020 with significant difference p<0.01. Flexibility of spine increased, so average difference in values before and after treatment for Shober test was 0.5 cm with SD 0.65. Difference test was t=3.794 with significant difference p<0.01. Brunkow exercises for low back pain are beneficial treatment for increasing flexibility and mobility of spine and improving the pain.
Contribution to the knowledge of position, flow and arterial distribution of cerebral blood vessels in foetuses 4 to 9 months of age
Authors: Kulenović Amela , Dilberović Faruk 
Published: May 2018

We studied cerebral blood vessels in 25 fetuses of gestational age 16-36 weeks and in 10 cadavers of still-born babies by injection-corrosive method. In the early fetal life, arteries are thin with the straight flow, which is directly connected with the brain development. Progressive changes are observed in all the three cerebral arteries in 28-week old fetus, which straight flow becomes more and more tortuous. As in the 32nd week the brain develops faster and gyri and sulci are being formed, the arteries assume wavy flow and number of their rami increases. In a still-born baby, arteries are of rather bigger caliber; they branch abundantly; and due to their relatively broad cerebral sulci, it can be said that their flow is partly tortuous. Our results show evidently that position, flow and relation of cerebral arteries change concurrently with the brain development and appearance of cerebral gyri and sulci.

In Federation of Bosnia and Herzegovina during 2002 a total of 67 cases of endometrial cancer (ICD 10th Revision Code C54) were registered among female population older then 15 years (1 per 10,000 population). Nine women were diagnosed with non specific malignant uteri neoplasia (C55)--without clarifying if that was cervix or corpus uteri located cancer, but assumption is that these cancers are actually endometrial cancer. Majority of cases are older then 50 years, 48 of them (71.6%), while 29 (28.4%) are from 15 to 49 years old. During 2000 about 189,000 new endometrial cancer cases were reported with 44,700 endometrial cancer deaths in the World. In this paper we presented geographical distribution of cases registered in FB&H, as well as leading risk factors, protective factors and prevention and possibilities for screening methods.
