Pensamiento trinitario y metafísica platonista en el De Generatione Divini Verbi de Mario Victorino
Authors: González Nares Gabriel
Published: June 2018

Mario Victorino Africano (n. ca. 300- m. 382 A.D.) representa elocuentemente el encuentro entre el cristianismo y el pensamiento platonista en el ambiente latino del siglo IV. En una de la obras de Victorino, el De Generatione Divini Verbi Victorino utiliza un aparato filosófico plotiniano para acercarse mejor a la teología cristiana en función de la solución de este problema trinitario: ¿Cómo genera algo el Uno sin dejar de ser Uno? El objetivo de este texto es analizar la convivencia del pensamiento teológico trinitario con la metafísica platonista plotiniana en el De Generatione Divini  Verbi en función de dos temas principales: 1) los modos de ser, y 2) la explicación de la vida del Uno más allá de la substancia. Primero  1) daremos una breve semblanza de la vida de Mario Victorino,  2) después, analizaremos  por qué el problema cristológico arriano necesita de una metafísica madura y sistemática para resolverse,  3) luego, repasaremos las soluciones que da Victorino en función del problema cristológico enfocándonos en los dos ejes mencionados, y 4) finalmente veremos las conclusiones de esta interacción entre teología y filosofía platonista mencionando la novedades que Victorino aporta a la comprensión de la metafísica platonista plotiniana.
La recepción kantiana de república, tolerancia e ilustración
Authors: Solari Enzo
Published: June 2018

Contra las tesis que sostienen que Kant presenta versiones empobrecidas, poco originales o timoratas de republicanismo, tolerancia e ilustración, aquí se argumenta que tales versiones kantianas son, con todos los matices que se quiera, tendencialmente radicales, y terminan por descansar en la coimplicación entre moralidad y estado constitucional y republicano de derecho.
Clostridium perfringens identifies source of pollution and reference streams in a tropical highland environment
Authors: Mushi Douglas
Published: June 2018

Clostridium perfringens was analysed in soils from a tropical highland catchment and corresponding headwater streams at baseflow condition in order to understand the contribution of soils to the microbiological quality of stream water and the feasibility of using these streams as surrogate for negative control (reference streams). The concentrations of C. perfringens depended on the sample matrix. C. perfringens concentrations were significantly higher in the catchment soil than in the stream water (P < 0.05, n = 20). In addition, C. perfringens concentrations in the catchment soil remarkably predicted C. perfringens concentrations in the stream water (i.e., 82% of variations in C. perfringens concentrations in water were predicted by C. perfringens concentrations in soil; P < 0.05, n = 20). This suggests that the catchment soils contributed C. perfringens to the stream water. Despite the observed contamination, the concentrations of C. perfringens (geometric mean of 32 cfu/100 cm3) in the stream water was below the recommended safe level for tropical freshwater systems and extremely lower than that detected in anthropogenically influenced rivers. This concentration was defined as an acceptable level of disturbance, and a reference concentration that can serve as surrogate for negative control in the studied tropical environment.

Authors: de Paula Soares Bruna , Climaco Leticia Rosa , de Almeida Lariana Negrão Beraldo , Lenzi Giane Gonçalves
Published: June 2018

The present work aimed at evaluating the photocatalytic process as an alternative for color removal from a synthetic solution (methylene blue dye) and of a sample of textile effluent, obtained from the various stages of the process, mainly dyeing. The parameters were evaluated using titanium dioxide (anatase, rutile, commercial and synthetized by the sol-gel method) in order to determine their structural influence in the discoloration of the samples. A synthetic methylene blue dye solution and a real effluent (Brazilian textile industry) were treated. The photocatalytic degradation was carried out over three hours in a batch reactor, under constant agitation, aeration, radiation and temperature. It was observed that the characteristics of each catalyst directly influence the photocatalytic activity. As a result, for the variables used in this work, the photocatalyst TiO2 anatase phase with a concentration of 1 kg/m³ was the most efficient condition, presenting full color removal for the methylene blue and 71% for the sifted textile effluent.
Diallyl Disulfide Inhibits Breast Cancer Stem Cell Progression and Glucose Metabolism by Targeting CD44/PKM2/AMPK Signaling
Authors: Xie Xinhua , Huang Xiaojia , Tang Hailin , Ye Feng , Yang Lu , Guo Xiaofang , Tian Zhi , Xie Xiaofang , Peng Cheng , Xie Xiaoming
Published: June 2018

Background:

It has been reported that diallyl disulfide (DADS) has anti-proliferative activity
in many cancers.

Objective:

The purpose of this study was to investigate the functions of DADS and the underlying
mechanisms of its effect in breast cancer stem cells (BCSCs).

Method:

Mammosphere formation assay, glucose consumption assay, lactate production assay and
mouse xenograft experiments were performed to explore the functions of DADS in BCSCs. ATPase
activity assay, western blotting and immunohistochemistry (IHC) assay were conduct to explore the
mechanisms underlying the effects of DADS in BCSCs.

Results:

The results showed that DADS suppressed cell stemness and glucose metabolism in
BCSCs. In vivo mouse xenograft experiments showed that DADS inhibited the proliferation and
metastasis of BCSCs. Then, we continued to explore the mechanisms underlying the effects of
DADS in BCSCs and found that DADS acts by targeting CD44, Pyruvate kinase M2 (PKM2) and
AMP-activated protein kinase (AMPK) signaling pathways. IHC analysis of 125 breast cancer patients’
tissues demonstrated that CD44, PKM2 and AMPK expression levels were positively correlated.
In addition, positive CD44, PKM2 and AMPK expression was associated with poor patient
overall survival (OS) and disease-free survival (DFS).

Conclusion:

In summary, DADS suppresses cell stemness, proliferation, metastasis and glucose
metabolism in BCSCs partly through the inhibition of CD44/PKM2/AMPK. DADS may be used as
a potential therapy for breast cancer treatment.
Tunneling Nanotubes: A Versatile Target for Cancer Therapy
Authors: Sahu Pragyaparamita , Jena Soumya Ranjan , Samanta Luna
Published: June 2018

Currently Cancer is the leading cause of death worldwide. Malignancy or cancer is a class
of diseases characterized by uncontrolled cell growth that eventually invade other tissues and develop
secondary malignant growth at other sites by metastasis. Intercellular communication plays a
major role in cancer, particularly in the process of cell proliferation and coordination which in turn
leads to tumor invasion, metastasis and development of resistance to therapy. Cells communicate
among themselves in a variety of ways, namely: i) via gap junctions with adjacent cells; ii) via
exosomes with nearby cells; and iii) via chemical messengers with distant cells. Besides, cell - cell
connection by tunneling nanotubes (TnTs) is recently gaining importance where intercellular components
are transferred between cells. In general cell organelles like Golgi vesicle and mitochondria;
and biomolecules like nucleic acids and proteins are transferred through these TnTs. These TnTs are
long cytoplasmic extensions made up of actin that function as intercellular bridge and connect a
wide variety of cell types. Malignant cells form TnTs with either other malignant cells or cells of the
surrounding tumor matrix. These TnTs help in the process of initiation of tumor formation, its organization
and propagation. The current review focuses on the role of TnTs mediated cell – cell signaling
in cancer micro-environment. Drugs that inhibit TnT-formation such as metformin and everolimus
can be targeted towards TnTs in the management of cancer growth, proliferation, tumor invasion
and metastasis.
Role of Glioma-associated GLI1 Oncogene in Carcinogenesis and Cancertargeted Therapy
Authors: Wu Jie , Di Dingxin , Zhao Chen , Liu Yingyi , Chen Hongxia , Gong Yan , Zhao Xianda , Chen Honglei
Published: June 2018

Glioma-associated oncogenes (GLIs) are zinc finger protein family members and downstream
regulatory factors of the classic Hedgehog (Hh) signaling pathway. GLI proteins influence
the growth and development of organisms and aid in tissue repair. However, aberrant expression of
the GLI family member GLI1 promotes carcinogenesis by inducing epithelial–mesenchymal transition
(EMT), angiogenesis, and other signaling pathways. Overexpression of GLI1 is thought to be
an indicator of poor prognosis as well as a potential therapeutic target for cancers. GLI inhibitors
such as zerumbone, GANT61, resveratrol, and cyclopamine depress the Hh pathway in vitro and in
vivo cancer research, and other non-canonical pathways may also activate expression of GLI1. Here,
we summarize GLI function in carcinogenesis and cancer-targeted therapy.

Authors: Abed Ziaeddin , Khoei Samideh , Ghalandari Behafarid , Beik Jaber , Shakeri-Zadeh Ali , Ghaznavi Habib , Shiran Mohammad-Bagher
Published: June 2018

Objective: To study the effects of ultrasound irradiation on the release profile of 5-fluorouracil (5-Fu)
loaded magnetic poly lactic co-glycolic acid (PLGA) nanocapsules. Also, the controlled drug-release behaviour
of the nanocapsules was mathematically investigated.

Methods:

The nanocapsules were synthesized, dispersed in phosphate buffered saline (PBS), transferred to a
dialysis bag, and finally, irradiated by various ultrasound parameters (1 or 3MHz; 0.3-1W/cm2; 5-10 minutes).
The release profile of the irradiated nanocapsules was recorded for 14 days. To find the in vitro drug release
mechanism in the absence and presence of various intensities of ultrasound, the obtained data were fitted in
various kinetic models for drug release.

Results:

The results demonstrated that the ultrasound speeded up the rate of drug release from the nanocapsules.
The mathematical analysis illustrated that when the ultrasound intensity is increased, the probability of controlled
release behaviour of the nanocapsules is raised. We found that drug release from the irradiated nanocapsules
follows an erosion-controlled mechanism with the decrease in the velocity of diffusion.

Conclusion:

In conclusion, to attain a controlled drug-delivery strategy in the area of cancer therapy, the drug
release profile of the nano-carriers may be well-controlled by ultrasound.
Social State Influences Memory in Novel Object Recognition Test Through Oxidative Stress Balance in Male Rats
Authors: Famitafreshi Hamidreza , Karimian Morteza
Published: June 2018

Objective:

Social isolation is associated with adverse effects on brain functions. According to previous studies, the reduction of oxidative stress improves cognitive functions. Memory performance is dependent on hippocampus and prefrontal function. The aim of this study is to show that impairment of memory in object recognition test in isolation state is accompanied by deregulation of oxidative stress balance in related areas.

Methods and Materials:

In this study, 14 male Sprague-Dawley rats were randomly divided into two groups as follows: social and isolation. Socialization and isolation plus one week of acclimatization occurred for fourteen days. At the end of the study, after performing behavioral test, (novel object recognition test) rats were anesthetized and sacrificed. After preparation of tissues in controlled condition, oxidative stress status in hippocampus and prefrontal cortex for Malondialdehyde (MDA), glutathione and nitrite/nitrate was assessed.

Results:

MDA in the hippocampus and prefrontal cortex was higher in isolated rats compared to social rats. Glutathione and nitrite/nitrate in the hippocampus and prefrontal cortex were lower in isolated rats compared to social rats. Memory performance in novel object recognition test both in short term and long term was better in social rats.

Conclusion:

Memory performance in novel object recognition test is influenced by social and oxidative stress status. So improving memory is possible through socialization and improvement of antioxidant status.

Published: June 2018

About half of patients with multiple sclerosis exhibit cognitive impairment which negatively affects their quality of life. The assessment of cognitive function in routine clinical practice is still undervalued, although various tools have been proposed for this reason. In this article, we describe the potential benefits of implementing cognitive assessment tools in routine follow -ups of MS patients. Early detection of changes in cognitive performance may provide evidence of disease activity, could unmask depression or medication side-effects and provide suitable candidates for cognitive rehabilitation. Since apathy and cognitive deficiencies are common presenting symptoms in Progressive Multifocal Leukoencephalopathy, we discuss the utility of frequent monitoring of mental status in multiple sclerosis patients at increased risk. In addition, we propose a relevant algorithm aiming to incorporate a systematic evaluation of cognitive function in every day clinical practice in multiple sclerosis.

Published: June 2018

Introduction:

Azomonas agilis, a nitrogen-fixing bacterium, was isolated from rhizospheric soil in central Myanmar.

Methods & Materials:

The nitrogen-fixing activity of this bacterium was detected by plate screening method using glucose nitrogen free mineral medium and ammonium test-kit Cellulolytic activity was screened by plat assay and detected by Dinitrosalicyclic acid method (DNS).

Results & Discussion:

The isolatedA. agilisgrew in media containing 3-12% of NaCl, although the growth became poor when NaCl concentrations increased. Among various carbon sources, sucrose was the best source for ammonium accumulation of this bacterium, whereas arabinose was not the suitable carbon source. Although the nitrogen-fixing activity ofA. agiliswas highest after one week incubation, cellulase enzyme production was highest after 2-3 days of incubation. It was observed that cellulase enzyme activity ofA. agilisfor cellulose and sodium carboxymethyl cellulose (CMC) was almost the same. Three agricultural wastes were used to detect the cellulase enzyme activity ofA. agilis, cellulase activity was better on filter paper as a substrate when compared to rice-straw and sawdust.

Conclusion:

So, the isolatedA. agilishas high potential as an effective bacterial strain to use in sustainable agriculture and degradation of some agricultural residues.

Authors: Bvumbwe Thokozani , Mtshali Ntombifikile Gloria
Published: June 2018

Background:

Malawi made great strides to increase the number of nurses through the Emergency Human Resource for Health Program. However, quantity of health workforce alone is not adequate to strengthen the health system. Malawi still reports skill mix imbalance and geographical mal-distribution of the nursing workforce. Health systems must continuously adapt and evolve according to the health care needs and inform health professionals’ education to accelerate gains in health outcomes. The Lancet Commission reported that health professionals’ education has generally not lived up pace with health care demands.

Objectives:

The aim of this study was to describe the strategies being implemented in Malawi to improve nursing education. Specifically, the objectives of the study were to explore strategies being implemented, identify stakeholders and their targets in order to share practices with countries experiencing similar nursing education challenges.

Methods:

This was a cross sectional descriptive study with a concurrent mixed method design. One hundred and sixty participants including nurse practitioners and educators responded to a questionnaire. Fifteen nurse practitioners and eight nurse educators were also engaged in one to one interview.

Results:

Respondents showed varied opinion on how nursing education is being implemented. Six themes as regards strategies being implemented to improve nursing education emerged namely- capacity building, competency based curriculum, regulation, clinical learning environment, transformative teaching and infrastructure/ resources.

Conclusion:

Findings of this study show that the strategies being implemented to improve nursing education are relevant to closing the gap between health care needs and nursing education.

Authors: Yirga Ashenafi Argaw , Ayele Dawit Getnet , Melesse Sileshi Fanta
Published: June 2018

Background:

Child malnutrition is the leading public health problem in developing countries. It is a major cause of child morbidity and mortality. Under-five children are the most vulnerable group for malnutrition. Body Mass Index (BMI) is a measure of nutritional status and is defined as the ratio of weight (kg) to squared height (m2). Studying the determinants of under-five children’s BMI is an important issue that needs to be addressed. This study applies quantile regression to study the determinants of under-five children BMI in Ethiopia.

Methods:

The weight-for-height index measures BMI. Quantiles are a generalization of percentiles for continuous random variables. Because it makes no distributional assumption about the error term in the model, quantile regression offers considerable model robustness.

Results:

The findings using quantile regression at different quantile levels were presented. The estimates across quantile levels were also performed. The findings of this study identified that for children under the age of five, the current age of mother, mother’s BMI, region (SNNPR and Somali) and weight of the child at birth (average and large) were found to be significantly affecting under-five children’s BMI across quantile levels.

Conclusion:

Quantile regression allows us to study the impact of predictors on different quantiles of the response distribution, and thus provides a complete picture of the relationship between the dependent and explanatory variables.
Review of Trademark and Its Enforcement Procedures of Pakistan under TRIPS and Paris Convention
Authors: Mukhtar Sohaib , Zainol Zinatul Ashiqin , Jusoh Sufian
Published: June 2018

Enforcement of trademark law has been in evolution for decades in Pakistan. Pakistani laws dealing with trademark and its enforcement procedures are Trade Marks Ordinance 2001, Trade Marks Rules 2004, Intellectual Property Organization of Pakistan Act 2012 and relevant provisions of Pakistan Penal Code 1860 and Specific Relief Act 1877. Civil procedure is dealt in Pakistan as per Code of Civil Procedure 1908 and criminal procedure as per Code of Criminal Procedure 1898. This article is qualitative method of research analyses trademark and its enforcement procedures of Pakistan as per relevant trademark laws of Pakistan under the light of relevant provisions of Agreement on Trade Related Aspects of Intellectual Property Rights (TRIPS) and Paris Convention. Paris Convention is the first International Convention containing trademark and its enforcement provisions (6-9) as TRIPS is the first International Agreement containing exhaustive provisions on trademark and its enforcement procedures (15-21, 41-61). Part III of TRIPS deals with enforcement of trademark including civil procedure, administrative procedure, provisional measures, border measures and criminal procedure of trademark enforcement. Trademark Registry established under section 9 of Trade Marks Ordinance 2001 and works under Intellectual Property Organization of Pakistan (IPO-Pakistan) which is a statutory body established under section 3 of Intellectual Property Organization of Pakistan Act 2012. The registered trademark owner in Pakistan can avail civil procedure, criminal procedure, administrative procedure as well as provisional and border measures for enforcement of his registered trademark right in Pakistan. TRIPS and Paris Convention have been ratified by Pakistan, but ratification of International Convention and its implementation are two different things. Better enforcement of trademark law may take years to achieve as per relevant provisions of International Conventions therefore designated authorities of Pakistan are required to establish more Trademark Registry branches, more IP Tribunals, appoint and induct more IP experts, examiners in-charge of registration and spread IP awareness throughout Pakistan for betterment of trademark law enforcement in Pakistan.

Published: June 2018

Corporate sustainability is a field in rapid development. As our global challenges gain more attention through the overarching strategies forged through for example, Agenda 2030—the role of companies become more important in working towards a sustainable world. Via interviews with students and sustainability professionals, this piece of research examines how the two different groups perceive the future of corporate sustainability and what companies should prioritize to be a part of the solution for a sustainable world. Three different themes per group arose as important, and the result shone a light on how differently the groups perceived responsibility for solving our shared challenges, as well as the need for collective frames as to what a company is and what purpose they serve in the world moving forward.

The impact of auditor rotation, audit firm rotation and non-audit services on earnings quality, audit quality and investor perceptions: A literature review
Authors: Velte Patrick , Loy Thomas
Published: June 2018

This literature review evaluates 103 empirical research studies on the link between rotation and non-audit services on the one hand and their influence on earnings quality, audit quality and investor perceptions on the other hand. After the financial crisis 2008/09, regulators all over the world are aware of decreased stakeholder trust in earnings and audit quality. As a reaction, stricter rules on rotation and non-audit services by public interest entities (PIEs) have been implemented (e.g. in the European Union). However, the impact of these regulations on earnings and audit quality is still controversial. We briefly introduce the theoretical, normative and empirical audit framework that comprises an adequate structure of the state-of-the-art of empirical research in this field. We summarize the findings in each research area, while we split our rotation analysis in an audit firm and audit partner rotation and tenure and our dependent variables in earnings quality, audit quality and investor perception measures. Most of the cited studies are linked to earnings-related measures, especially abnormal accruals models. The mixed results can be explained by the different theoretical impacts of agency- and resource-based view. Finally, we will discuss the current limitations of the studies and give useful recommendations for future empirical research activities on this topic
Some problems connected with boron determination by atomic absorption spectroscopy and the sensitivity improvement
Authors: Pavlovic Mirjana , Savovic Jelena , Marinkovic Momir
Published: June 2018

Two atomizers were compared: an N2O-C2H2 flame and a stabilized U-shaped DC
arc with aerosol supply. Both the high plasma temperature and the reducing
atmosphere obtained by acetylene addition to the argon stream substantially
increase the sensitivity of boron determination by atomic absorption
spectroscopy (AAS) when the arc atomizer is used. The results were compared
with those for silicon as a control element. The experimental characteristic
concentrations for both elements were compared with the computed values. The
experimentally obtained characteristic concentration for boron when using
the arc atomizer was in better agreement with the calculated value. It was
estimated that the influence of stable monoxide formation on the sensitivity
for both elements was about the same, but reduction of analyte and formation
of non-volatile carbide particles was more important for boron, which is the
main reason for the low sensitivity of boron determination using a flame
atomizer. The use of an arc atomizer suppresses this interference and
significantly improves the sensitivity of the determination.

Published: June 2018

The complexes of light lanthanides with 2,3-dimethoxybenzoic acid of the
formula: Ln(C9H9O4)3, where Ln = La(III), Ce(III), Pr(III), Nd(III),
Sm(III), Eu(III) and Gd(III) have been synthesized and characterized by
elemental analysis, IR spectroscopy, thermogravimetric studies, as well as
X-ray and magnetic measurements. The complexes have colours typical for Ln3+
ions (La, Ce, Eu, Gd-white, Sm-cream, Pr-green, Nd-violet). The carboxylate
group in these complexes is a bidentate, chelating ligand or a tridentate
chelating and bridging one. They are crystalline compounds characterized by
low symmetry. On heating in air to 1173 K, the 2,3-dimethoxybenzoates of the
light lanthanides decompose in various ways. The complexes of Ce(III),
Pr(III), Sm(III), Eu(III) and Gd(III) decompose directly to oxides of the
respective metals while those of La(III) and Nd(III) via the intermediate
formation of La2O2CO3 and Nd2O2CO3. The solubilities of the
2,3-dimethoxybenzoates of the light lanthanides in water at 293Kare in the
orders of 10-3-10-2 mol dm-3. The magnetic moments were determined in the
range 4.2-298 K and the complexes are found to obey the Curie-Weiss law.

Authors: Popovic Milica , Papic Milos , Acovic Aleksandar , Zivanovic Suzana , Kanjevac Tatjana
Published: June 2018

Introduction. The aim of this study was to establish the number of roots and
present the root canal configuration in the maxillary and mandibular
premolar teeth, and evaluate the relations among these characteristics with
gender and teeth position in the Serbian population using cone-beam computed
tomography. Material and Methods. Cone-beam computed tomography images of
570 teeth of 150 patients were evaluated. Teeth were classified into the
following groups: maxillary first premolars, maxillary second premolars,
mandibular first premolars and mandibular second premolars, and the number
of roots and root canals per tooth, whereas root canal configurations were
examined along with the tooth position and patients? gender. The root canal
configuration was classified using Vertucci?s classification. Statistical
significance was obtained using Chi square test. Results. In maxillary first
premolars, two roots (53.5%) and two root canals (84.5%) were the most
prevalent, as well as type IV configuration (58.9%). In maxillary second
premolars, most teeth had one root (88.1%) and one root canal (59.6%). In
regard to gender, complex configurations with multiple canals were more
prevalent in males. Higher incidence of type IV configuration in maxillary
first premolars was present on the right side of the jaw (70.2%). Most
mandibular first premolars had one root (98.5%). In mandibular second
premolar, all teeth had one root and most had type I configuration (96.2%).
Males showed higher incidence of two canals in mandibular first premolars.
Conclusion. Cone-beam computed tomography is a useful tool for obtaining
valuable information on root canal morphology of premolar teeth. Patient?s
gender should be considered when performing the preoperative assessment of
endodontic treatment.
Treatment history: Factors that affect the outcome of hepatitis c virus treatment with interferon-alpha 2a/b and ribavirin
Authors: Spasojevic Tijana , Bujandric Nevenka , Vujanovic Milos
Published: June 2018

Introduction. Until the 1990s, there was no available treatment for chronic
hepatitis C, but during this decade the benefits of interferon-alfa therapy
were reported. At the end of the 1990s, the pegylated interferon-alfa 2a/b
has significantly altered the treatment, whereas direct acting antivirals
have significantly affected the treatment. The aim of this study was to show
the most significant predictive factors of therapy response among patients
with chronic hepatitis C treated with pegylated interferon- alfa 2a/b and
ribavirin. Material and Methods. A non-randomized retrospective study
included 292 patients with chronic hepatitis C treated at the Clinic for
Infectious Diseases, Clinical Center of Vojvodina, from 2008 to 2015.
Results. The study showed that therapeutic response was not affected by sex,
serum viral load, or if the therapy was applied for the first time or
repeated. A sustained virological response was statistically significantly
more frequent in younger patients, as well as in patients without
extrahepatic manifestations. Cases with higher progression of fibrosis were
associated with lower chance for sustained virological response. Genotype 1
showed to be a predictor of adverse response to therapy, and genotype 3 as a
predictor of sustained virological response. Steatosis was significantly less
frequent in patients with genotype 1 with sustained virological response.
Patients with a shorter duration of infection were more prone to sustained
virological response. Conclusion. A positive response to pegylated
interferon-alfa 2a/b and ribavirin was found in 70.20% of patients with
chronic hepatitis C. Elderly age, late detection of the infection, hepatitis
C virus 1 genotype, fibrosis progression, presence of hepatic steatosis, and
extrahepatic manifestations were risk factors for poor treatment outcome.
Primary diffuse large B-cell lymphoma of the oral cavity: A case report
Authors: Ilic Aleksandra , Savic Ivanka , Fejsa-Levakov Aleksandra , Bajkin Branislav
Published: June 2018

Introduction. Lymphomas are a group of neoplasms of the lymphatic and
reticuloendothelial system. The two main types are Hodgkin lymphoma and
non-Hodgkin lymphoma, depending on the immunohistological characteristics of
malignant lymphocytes. B-cell lymphomas are more frequent than T-cell
lymphomas. In this case report we present a male patient with diffuse large
B-cell lymphoma localized in the maxilla. Case Report. A 59-year-old man
presented with a painless swelling in the right posterior region of the
maxilla. A solid tumor was found in the right posterior maxillary region by
intraoral examination, firstly suspected as a dental infection. Since the
symptoms did not improve a month after the first dental treatment, he was
referred for further diagnostic evaluation. The established diagnosis was
diffuse large B-cell lymphoma. The patient received standard therapy for
diffuse large B-cell lymphoma - rituximab-cyclophosphamide,
hydroxydaunomycin, oncovin, prednisolone, six cycles and regression of the
oral lesion was noticed. Conclusion. Lymphoma of the oral cavity usually
presents as a swelling and may mimic odontogenic infection. Dentists should
be aware of this possibility especially if the swelling is painless and if
the initial treatment has failed.

of blood which passes through individual layers of the blood vessel or
through all layers, but it is retained in the surrounding soft tissues. Case
Report. We report presents a 41-yearold patient with a large idiopathic
pseudaneurysm of the second segment of the popliteal artery, referred by an
orthopedist with a magnetic resonance image of the left leg. The patient?s
medical history showed that the pain started three weeks ago, the swelling in
the left popliteal fossa about 6 months ago, and a large, painful,
non-pulsatile tumefaction was found during the examination, resulting in a 90
degrees flexion contracture of the left knee. The magnetic resonance showed a
pseudoaneurysm of the left popliteal artery, and an emergency computed
tomography angiography was performed; it confirmed a pseudoaneurysm of the
left leg second segment of the left popliteal artery without signs of
obliterative diseases. The posterior approach and exposition of the popliteal
artery was applied; autovenous graft interposition with a great saphenous
vein of the right leg was done. Conclusion. Early diagnosis plays an
important role in avoiding temporary and permanent complications. Arterial
reconstruction with autovein grafting is a gold standard and a method of
choice in the surgery of the pseudaneurysm of the popliteal artery. The
temporary setting of occlusive Fogarty catheters reduces damage to the
surrounding tissue, accelerates bleeding control, which together shortens the
time of surgery.

There are diverse relationships between mites and birds or mammals. These mites may play an important role in epizootics and in the perpetuation of some significant diseases. The purpose of this study is to revise the current knowledge of mesostigmatic mites occurring on birds, including their nests and mammals and their substrates, in Iran and to compare the results with other regions of the Palearctic ecozone. This study presents a revised list of 38 species of mesostigmatic mite occuring on birds (17 species) and mammals (24 species) or in their nests/substrates in Iran. Dermanyssus gallinae, Ornithonyssus sylviarum and Parasitus hyalinus were found on both birds and mammals. The species composition of mites reported in Iran was compared with other regions of the Palearctic ecozone. Parasites, specifically those from genera Dermanyssus, Ornithonyssus and Liponyssoides, may be hazardous to human health. Species from these genera were predominant among the reported mites.
www.lasst-uns-streiten.de -- Die Dialogplattform der Sächsischen Landeszentrale für politische Bildung

Published: June 2018

Die Sächsische Landeszentrale für politische Bildung hat unter www.lasst-uns-streiten.de eine moderierte Online-Dialogplattform ins Leben gerufen, die eine sachliche Auseinandersetzung zu politisch kontroversen Themen ermöglichen soll. Für einen Zeitraum von jeweils vier Wochen wird ein politisch brisantes Thema zur Diskussion gestellt. Das Thema wird in vier kontroverse Thesen aufgespalten, die unterschiedliche Perspektiven auf das Thema wiedergeben. Die NutzerInnen haben die Möglichkeit, über die Thesen abzustimmen und müssen ihre Meinung begründen. Anschließend werden die DiskutantInnen mit einer entgegengesetzten Meinung konfrontiert. An diesem Punkt unterscheidet sich die Plattform von allen übrigen Diskussionsangeboten im Netz: An die Stelle der komfortablen „Filterblase“ (Pariser, 2011), die überwiegend die eigene Meinung bestärkt, tritt ein moderierter Diskussionsraum, in dem Meinungsbildung auf der Basis von Hintergrundinformationen und in der Auseinandersetzung mit Andersdenkenden erfolgen kann. Auf diese Weise kann Streit- und Diskussionskulturerprobt werden.
Die Instrumentalisierung partizipativer Öffentlichkeit durch die AfD bei der rheinland-pfälzischen Landtagswahl 2016

Onlineangebote wie Facebook bieten günstige Voraussetzungen für Diskurse. Allerdings werden Diskurse im Rahmen partizipativer Öffentlichkeitsmodelle meist vor dem Hintergrund einer angestrebten Demokratisierung beleuchtet. Gleichzeitig ermöglichen partizipative Ansätze die Ableitung von Annahmen, wie Diskurse verlaufen, wenn die TeilnehmerInnen nicht das Ziel einer Demokratisierung verfolgen. Vor diesem Hintergrund setzt sich der Beitrag mit der Frage auseinander, wie die AfD als rechtspopulistische Partei Facebook im Vergleich zu anderen Parteien als Wahlkampfinstrument nutzt. Im Mittelpunkt steht dabei, wie sich eine Kommunikationsplattform mit hoher Zugangsfreiheit und eine dem Populismus eigene Kommunikationsstrategie des ‚einfachen Bürgers‘ gegen eine ‚korrupte Elite‘ gegenseitig ergänzen können. Zur Beantwortung der zentralen Frage verbindet die Studie eine qualitative Befragung von WahlkampfstrategInnen von sechs Parteien mit einer quantitativen Befragung aktiver WahkampfhelferInnen. Die Ergebnisse zeigen, dass die AfD Facebook sehr zielgerichtet und bewusst nutzt, um eine Gegenöffentlichkeit zu schaffen. Durch den strategischen Einsatz von Facebook-Posts, setzt sie auf die Entstehung von Echokammern und testet das Meinungsklima ihrer AnhängerInnen.
