Mitochondrial DNA Copy Number Variation as a Potential Predictor of Renal Cell Carcinoma
Authors: Elsayed Eman T. , Hashad Mohamed M. , Elgohary Iman E.
Published: May 2017

Background

Peripheral blood mitochondrial DNA (mtDNA) copy number alteration has been suggested as a risk factor for several types of cancer. The aim of the present study was to assess the role of peripheral blood mtDNA copy number variation as a noninvasive biomarker in the prediction and early detection of renal cell carcinoma (RCC) in a cohort of Egyptian patients.

Methods

Quantitative real-time polymerase chain reaction (qPCR) was used to measure peripheral blood mtDNA copy numbers in 57 patients with newly diagnosed, early-stage localized RCC and 60 age- and sex-matched healthy individuals as a control group.

Results

Median mtDNA copy number was significantly higher in RCC cases than in controls (166 vs. 91, p<0.001). Increased mtDNA copy number was associated with an 18-fold increased risk of RCC (95% confidence interval: 5.065-63.9). On receiver operating characteristic curve analysis, it was found that mtDNA could distinguish between RCC patients and healthy controls, with 86% sensitivity, 80% specificity, 80.3% positive predictive value and 85.7% negative predictive value at a cutoff value of 108.5.

Conclusions

Our results showed that increased peripheral blood mtDNA copy number was associated with increased risk of RCC. Therefore, RCC might be considered as part of a range of potential tumors in cases with elevated blood mtDNA copy number.

Authors: Tirtei Elisa , Asaftei Sebastian D. , Manicone Rosaria , Cesari Marilena , Paioli Anna , Rocca Michele , Ferrari Stefano , Fagioli Franca
Published: May 2017

Purpose

Osteosarcoma (OS) is the most common primary bone tumor. Despite complete surgical removal and intensive chemotherapeutic treatment, 30%-35% of patients with OS have local or systemic recurrence. Some patients survive multiple recurrences, but overall survival after OS recurrence is poor. This analysis aims to describe and identify factors influencing post-relapse survival (PRS) after a second OS relapse.

Methods

This is a retrospective analysis of 60 patients with a second relapse of OS of the extremities in 2 Italian centers between 2003 and 2013.

Results

Treatment for first and subsequent relapses was planned according to institutional guidelines. After complete surgical remission (CSR) following the first recurrence, patients experienced a second OS relapse with a median disease-free interval (DFI) of 6 months. Lung disease was prevalent: 44 patients (76%) had pulmonary metastases. Survival after the second relapse was 22% at 5 years. Lung disease only correlated with better survival at 5 years (33.6%) compared with other sites of recurrence (5%; p = 0.008). Patients with a single pulmonary lesion had a better 5-year second PRS (42%; p = 0.02). Patients who achieved a second CSR had a 5-year second PRS of 33.4%. Chemotherapy (p<0.001) benefited patients without a third CSR.

Conclusions

This analysis confirms the importance of an aggressive, repeated surgical approach. Lung metastases only, the number of lesions, DFI and CSR influenced survival. It also confirms the importance of chemotherapy in patients in whom surgical treatment is not feasible.

Authors: Rapoport Leonid M. , Cytron Shmuel , Enikeev Mikhail E. , Tsarichenko Dmitry G. , Enikeev Dmitry V. , Chinenov Denis V.
Published: May 2017

Introduction

The article describes the first experience of performing percutaneous ultrasound (US)-guided cryoablation of renal tumor and assesses the safety and short-term results of treatment.

Materials and Methods

Twelve patients were subjected to US-guided cryoablation of renal tumor in 2015. The tumor size in 11 patients was up to 3.0 cm (T1а); in one female patient, 4.5 cm (T1b). Tumors were assessed according to the PADUA score. In eight patients, it was 6-7 (low); in three patients, 8-9 (average); in one, 10 (high). All the patients underwent US examination using a FlexFocus 800 apparatus with convex abdominal transducers. Before surgery and 6 months later, all the patients underwent renal Doppler US and contrast-enhanced computed tomography.

Results

The average cryoablation time was 60 min. Seven operations were performed under spinal anesthesia and five operations under local anesthesia. The follow-up period lasted 8 months on average. According to the ultrasonography and Doppler findings, after 6 months, the tumor (T1a) in 11 patients reduced in size by an average of 7-8 mm and had no blood supply. T1b patient's mass size reduces from 4.5 to 3.7 cm; however, a 1.5 cm area with a high attenuation gradient of the contrast medium was visualized. Later, the patient was subjected to laparoscopic renal resection. Histological finding revealed clear-cell carcinoma.

Conclusions

We consider percutaneous US-guided cryoablation as a method of choice for patients with stage T1a renal tumor localized on the posterior or lateral surface in the inferior or middle segment without sinus involvement and PADUA <9.

Published: May 2017

Introduction

We present a case of a spongiosus-cutaneous fistula in a 39-year-old man with recurrent episodes of cutaneous abscess in dorsal middle third penis (5 × 3 cm) treated with Hyperbaric Oxygen Therapy (HBOT).

Case report

After emptying nodular abscess, the patient was noncompliant for further surgery. Therefore, it was suggested the association between HBOT and antibiotic therapy. HBOT is carried out in a hyperbaric room, where the internal pressure is increased (compression phase) by entering compressed air up to 283.71 kPa in about 10 minutes. Every HBOT cycle lasted 24 days in which the patient had been taking Amoxicillin/Clavulanic Acid 875 mg/125 mg 3 tabs/day and Sulfamethoxazole/Trimethoprim 160 mg/800 mg 2 tabs/day for 2 weeks. At the end of the treatment, a penile magnetic resonance imaging and an ultrasonography were executed and they evidenced a complete remission of the lesion. In the subsequent 22 months, there was no recurrence.

Conclusions

Our results suggest that HBOT is an effective treatment for chronic wounds, including a spongiosus-cutaneous fistula of unknown cause, when used in combination with conventional standard therapy or further interventions. At present time, the gold standard remains surgery; nevertheless, our experience with HBOT may stimulate its use in clinical trials.

Published: May 2017

O presenta artigo aborda uma maneira diferenciada de inovar por meio do Design, pautada na mudança de perspectiva: do Design centrado no usuário para o Design centrado no significado. Nessa perspectiva, a inovação pode ser obtida com menos investimentos, desde que a empresa adquira a capacidade de perceber o significado que as pessoas atribuem aos produtos. Além disso, esse texto estabelece uma relação entre a educação em Design e a capacidade do profissional de gerar inovação. Sugere que uma mudança no processo pedagógico atual, disciplinar e limitador, para o interdisciplinar, cuja proposta pode ser metaforicamente comparada a uma rede com múltiplas conexões, poderá favorecer a formação de designers que apliquem essa nova perspectiva de inovação.

Book Review: Exploring Discovery: The Front Door to Your Library’s Licensed and Digitized Content
Authors: Nelson Laura
Published: May 2017

We are well into the twenty-first century and many libraries, large and small, are dealing with the ever-evolving subject of discovery. This book does an excellent job of covering the many discovery interfaces and platforms available and their impact at various libraries. Discovery is, to quote a statement given in chapter 10 of this book, “enabling people to pick out what they need from an otherwise unmanageable mass of information” (120). Given the changing roles of libraries, as well as the multitude of different media types with which libraries must now deal and must make accessible to patrons, discovery is more important than ever before. Thus, this growing need for discovery that is user-friendly, all encompassing (or nearly so) and fairly intuitive on the back end has given birth to a plethora of options, all of which have their benefits and drawbacks. As not every library or collection is identical, so can be said for the various discovery platforms explored in this work.

Expectation vs Reality : A Study on the Significance of Practical Training for Future Graduates
Authors: Abidin Saidatul Akmar Zainal , Jamil Asiah Hj , Abdullah Normah
Published: May 2017

This paper reports the significance of an internship experience which is intended to assist students to obtain jobs as soon as they graduate. It also discusses some of the reasons graduates fail to obtain jobs after graduation. Feedback from employers (from place of internship) via questionnaires and interviews was analysed to gain insight into what employers expect from graduates, how the graduates performed during the internship and what is expected of them in the future. One of the common problems cited by stakeholders/employers is graduates do not have the necessary skills to perform certain jobs. It was discovered that employers expect the graduates to posses a high communicative ability, to be well motivated, to have positive attitude, willingness to learn and interpersonal skills. In addition, some of these future graduates were found to be lacking in commitment, perseverence and knowledge of office etiquette. This paper highlights the crucial role that internship plays in ensuring that graduates secure employment after graduation. Internships greatly increase the chances that a student will gain full time employment after graduation. Reports often reveal that while prospective employers have specific expectations of the interns and that some are willing to provide training, they are confronted with issues relating to candidates’ language proficiency and their competence in a number of soft skills.
Quantitative, Qualitative or Mixed Research: Which Research Paradigm to Use?
Authors: Khaldi Kamel
Published: May 2017

Research students usually encounter great difficulties in setting up a viable research project mainly because, on the one hand they lack familiarity with the philosophical underpinnings of major paradigms used in educational research: quantitative, qualitative or mixed, and on the other hand , they do not associate the corresponding research types with these paradigms : experimental, non experimental for the former, and interactive or non interactive for the second and the for the latter whether it is explanatory or exploratory, in addition to the importance of triangulation in any research study . These paradigms determine not only the formulation of the problem chosen for research and the associated research questions or hypothesis but also and more importantly, the sampling procedure as well as the selection of the appropriate research tools and the way the collected data is analysed and discussed. This survey of the major paradigms in educational research and their implications for the design of any research study will hopefully provide them with the necessary guidance to approach their research project with more confidence et more efficiency.
Racial Composition of School District on School Leaders′ Responses to State Takeover: A Field Experiment on the Application of Michigan’s Emergency Manager Law
Authors: Vang Maiyoua
Published: May 2017

Michigan’s Public Act 436, commonly referred to as the Emergency Manager Law, has provided for state installed emergency managers to oversee financially distressed municipalities as well as school districts. Given that a number of Michigan school districts, suburban, rural, and urban, have been operating at a deficit for several years and yet only the financial status of majority Black school districts (Detroit, Highland Park, Muskegon Heights) have triggered this takeover law, this field experiment investigated the effect of school district’s racial composition on both the level of support for state-installed emergency managers in districts and the level of support for politically material resistance to the application of that remedy. Implications regarding policy and critical policy research are forwarded in light of the results.

Accreditation is carried out to ensure that universities meet acceptable standards of quality in its programme offerings. This paper, which examined politics of National Universities Commission programme accreditation practices used descriptive survey design. The research covered universities in Akwa Ibom and Cross River States, Nigeria. Three research questions were raised to enhance the study. Purposive sampling technique was utilized to raise a sample of 85 current and former Heads of Departments for the study. A 21 - item instrument titled “Politics of Accreditation Practices Questionnaire (PAPQ)” was drawn, validated and tested for reliability using Cronbach Alpha. The index of reliability was 0.84 which indicated the fitness of the instrument for use. Data derived from the instrument were analyzed using means and standard deviation. Findings indicated that politics has been part of programme accreditation practices. Aspects of politics of accreditation identified were: politics of funding, borrowed books to boost library stock, borrowed facilities, window dressing of facilities, among others. The major challenges to programme accreditation as identified by the respondents were inadequate funding, inadequate and obsolete facilities and too much paper documentation. Suggestions to remedy the challenges to accreditation included that adequate funds should be made available to universities and internal mechanism for quality assurance should be strengthened within the universities.

Published: May 2017

Coevolution originated as a biological concept has traditionally been associated with the biological sciences to describe those cases of mutual evolutionary influence involving two (or more) species. This concept is fairly new in the study of organizations as it was introduced only two decades ago, specifically refers to a process involving successive changes between businesses and the environment. More recentrly, researchers began to employ the coevolution as an alternative to overcome the business turbulence with great success that would otherwise put its existence at risk. This article delimits the organizational coevolution concept making a direct association with business turbulence. It is being presented in the form of a multiple-case study of the mobile telephony industry in Colombia with a qualitative methodology. As part of the information-gathering process, approximately 300 public and private documents were consulted and 50 interviews with key stakeholders of the industry were conducted. Content analysis is the main data analysis technique, and the ATLAS/ti is used for processing. Thus, the final results show that when a sector faces turbulence, businesses can efficiently manage this phenomenon if they undertake a structural coupling process between the turbulent environment and strategic behaviour.

Published: May 2017

Patriarchal culture has become the dominant issue in online media. Recently, online news and advertising media have less gender perspective. Its content tends to position women as marginalized subjects receiving negative stereotypes. This study aims to review women’s reality in online media, in the form of: 1) news published on tribunnews.com; 2) how women issues are presented by using gender perspective journalism. This research uses descriptive qualitative content analysis approach combined with discourse analysis method of Sara Mills with a focus on the position of the subject and the object. Tribun daily Media in its online form (www.tribunnews.com) is the locus of this research. Tribunnews.com is selected because it ranks in big three news portal in Indonesia, having an extensive and strong network as they are supported by more than twenty regional press. The results show that media has not been fully able to raise women’s issue in the mainstream. The media still portrays women within the bond of patriarchal culture, discrimination, and consumeristic lifestyle. The power of patriarchy dominates the news which marginalizes women. News content and its features follow the pattern of male dominating power. Tribunnews.com has been legitimizing gender bias by accepting exploitation on female’s physical appearance as normal and acceptable. In other instances, Tribunnews.com does not highlight intellectual and leadership values of women as actors. News in online media should be reformed to be more gender sensitive.

Consumer Dispute Resolution: A Comparative Study between Indonesia and Common Law System Countries
Authors:   Kurniawan
Published: May 2017

Since 2001, based on the mandate of Article 49 paragraph (1) of Law no. 8 of 1999 on Consumer Protection, BPSK (Badan Penyelesaian Sengketa Konsumen/Consumer Dispute Resolution Institution) has been established based on Presidential Decree No. 90/2001 on the establishment of BPSK in several cities in Indonesia. In some countries that embrace the Anglo Saxon legal system, consumer dispute cases are resolved by an institution called The Small Claims Court (SCC) and The Small Claims Tribunal (SCT). The difference in settlement through three institutions is that BPSK is a formal institution which resolves small disputes with low-cost, but does not limit the size of the lawsuit filed by consumers. On the other hand, SCT provides clear restrictions on claims that can be filed by consumers. At the completion done by SCC, the assemblies that resolved the case come from active and retired judges, while in BPSK the assemblies come from government, businessman and consumer with different backgrounds.

For the first time, complex studies were carried out on adsorption deformation – sorbostriction of microporous carbon adsorbent FAS-3 at adsorption of hexane, benzene and carbon tetrachloride from the flow of carrier gas – nitrogen in non-equilibrium conditions. The results of this phenomenon were analyzed. In work a microporous carbon adsorbent FAS-3, obtained on the basis of furfural was used. Active coals on the basis of thermosetting plastics grades of FAS are significantly better than commercially-produced carbon adsorbents based on coal and peat on their mechanical properties and low ash content at a much greater development of the volume of the adsorbent micropores. We used the facility for studies of adsorption deformation of a solid adsorbent, manufactured in the Institute of Physical Chemistry and Electrochemistry of RAS. For the measurements we used a flow dilatometer, allowing measuring the adsorption deformation of the adsorbent while passing through it portions of the test substance or mixture in the carrier gas flow. It is shown that values of the maxima on the curves of deformation increase with increasing the concentrations of the components of the mixture. The area under the curve of barbastelle depends on the amount of injected material in a flow of carrier gas. Exit time curves of barbastelle to the maximum is individually for each of the studied substances, which enables you to use the effect of barbastelle to detect the presence of certain substances in the mixture. The results of the wave sorbostriction of microporous carbon adsorbent FAS-3 at adsorption of benzene, hexane, carbon tetrachloride from the flow of carrier gas -  nitrogen allow to conclude on the high selectivity of adsorption and the possibility of using the adsorbent as a sensor to control the content of these substances in a flow of nitrogen.For citation:Zaytsev D.S., Tvardovskiy A.V., Shkolin A.V., Fomkin A.A.

The possibility of the synthesis of (E)- and (Z)-isomers of 2-(3-chloroprop-2-en-1-yl)cyclopentanone based on allylation of an available ethyl 2-oxocyclopenthanecarboxylate by individual isomers of 1,3-dichloropropene followed by decarboxylation of the resulting isomers of ethyl 1-(3-chloroprop-2-en-1-yl)-2-oxocyclopenthanecarboxylate was investigated. The allylation of ethyl 2-oxocyclopenthanecarboxylate by (E)- or (Z)-isomers of 1,3-dichloropropene under the phase-transfer catalysis conditions in the presence of K2CO3 smoothly leads to the corresponding isomers of ethyl 1-(3-chloroprop-2-en-1-yl)-2-oxocyclopenthanecarboxylate with 84 and 80% yields, respectively. Decarboxylation of alkylated ketoesters under basic conditions leads to ring opening and formation of the corresponding α-substituted adipic acids, and under acid conditions in unacceptably low yields of ketones. Best results are obtained by decarboxylation of isomers of ethyl 1-(3-chloroprop-2-en-1-yl)-2-oxocyclopenthanecarboxylate under Krapcho conditions. However, in this case a side-formation of the corresponding α-substituted mono- and diethyl esters of adipic acid is observed too. The optimization of the reaction showed that the addition of acetic acid as the proton donor suppresses almost completely the ring opening. The decarboxylation in N-methylpyrrolidone at a temperature of 130-150 °C in the presence of 3 eq. LiCl, 2 eq. water and 2 eq. acetic acid affords to (E)- and (Z)-isomeric 2-(3-chloroprop-2-en-1-yl)cyclopentanones with 75-77% yields and stereochemical purity of ~ 99%.Forcitation:Alieva R.M., Sunagatullina A.Sh., Shakhmaev R.N., Zorin V.V.

The synthesis of the complexes of Cu, Ni, Co, Pd, Sn, Hg of 1',7',7'-trimethylbicyclo[2.2.1]heptano-[2',3'-b]-2,3-pyrazinoporphyrazine for new materials for variety of potential applications is described. Metallic complexes were synthesized by the template cyclotetramerization of dicarbonitrile with metal chlorides at temperature 140-150 ºС for 20 min. Ammonium molybdate tetrahydrate was used as a catalyst. The products were purificated by chromatography on silica gel (eluent -chloroform). Complexes of Pd, Sn and Hg were synthesized for the first time. The metallocomplexes of camphor-substituted tetrapyrazinoporphyrazine are crystalline substances of dark blue color, not fusible up to 300 ° C, which have good solubility in chloroform, toluene, ethanol, acetone, DMF, acetic and trifluoroacetic acids. The chemical structures of the complexes of Cu, Ni, Co, Pd, Sn, Hg of 1',7',7'-trimethylbicyclo[2.2.1]heptano-[2’,3’-b]-2,3-pyrazinoporphyrazine obtained in this study were characterized by proton nuclear magnetic resonance and mass spectrometry. The absence of impurity signals in the 1H NMR spectra indicates a high degree of purity of the compounds obtained. For copper, nickel and cobalt complexes, a good correlation was found between the experimental and literature data on the chemical shifts of protons in 1H NMR spectra. Optical properties of the synthesized complexes were studied. The electronic absorption spectra of the complexes in their chloroform, DMF, acetic acid and sulfuric acid solutions were obtained. In organic solvents the typical B band (Soret band, around 400 nm) and Q band (in 600-700 nm region) of phthalocyanines were identified in this study. Complexes of Pd, Sn and Hg in their sulfuric acid solutions are non-stable. The influence of the chemical structure of metalic complexes and solvents on the optical properties was studied. Emission properties of the synthesized complexes of Pd and Hg in their chloroform and DMF solutions were analyzed. Hg-porphyrazine has very intensive fluorescence. The solution has blue color and red fluorescence at common condition.Forcitation:Kuvshinov G.V., Ziyadova T.M., Kuvshinova S.A., Koifman O.I.

An urgent task is to develop new methods of obtaining porous carbon materials with required complex of properties of cheap raw materials, for example, wastes of mechanical and chemical wood processing. This article deals with the subject of production of activated carbon for supercapacitors with different electrolytes. Activated carbons produced from two wood species, birch and alder, were compared. For both carbons identical dependences of the porous structure and electrochemical parameters of the carbons on activation conditions were determined in a wide range of activation parameters (temperature, alkali/carbon mass ratio). The work was done on the basis of commercial coals of alder. The correlations between the activation parameters of coal (temperature of activation and the relationship of the activator/raw materials), porous structure and functional parameters of capacitors were established. It was established that the acceptable value of the temperature of activation for aqueous electrolyte was 600 °C, and the ratio of activator/raw = 1.25, for organic – 600 °C, the ratio of the activator/raw = 2. A comprehensive study of carbon properties was conducted including a detailed study of the porous structure by the method of limited evaporation and electrochemical parameters of activated carbon in the composition of the supercapacitors. Assumptions were made on the features of formation of porous structure of activated carbons obtained by thermo-chemical synthesis using alkali as an activator, and on the influence of synthesis parameters on the electrochemical characteristics of the supercapacitors.Forcitation:Zhurilova M.A., Yanilkin I.V., Kiseleva E.A., Atamanyuk I.N., Shkolnikov E.I.

SYNTHESIS OF N-HYDROXYINDOLES
Authors: Chirkova Zhanna V.
Published: May 2017

The basic synthetic methods for obtaining N-hydroxyindoles were studied. The first method is intramolecular reductive cyclization of ortho-substituted nitroaromatic compounds by various reducing agents. Nitrophenyl acetaldehydes (synthesis by Acheson), N,N-disubstituted amino-2-nitrostyrenes (synthesis by Somei), ortho-nitroketoetheres of different structure or 1-(o-nitroarene)-1-cyanoalkylnitroketones, ortho-nitrophenylacetonitriles were used as substrates for the synthesis of N-hydroxyindoles. Titanium chloride (III), zinc in THF solution of ammonium chloride or in acetic acid, stannous chloride in ethanolic HCl, and hydrogen with application of catalytic agent on basis of noble metals (platinum, palladium) were used as reduction agents. The second method is a [3+2]-cycloaddition with nitrozoaromatic compounds to alkynes or deoxygenation ortho-nitro substituted aromatic compounds with subsequent intramolecular cyclization. The third method is catalytic oxidation of 2,3-dihydroindoles or different indoles by concentrated hydrogen peroxide with application of of tungstate sodium as catalyst. We attended special attention to synthesis of functional derivatives of N-hydroxyindole-5,6-dicarboxylic acids because these compounds were synthesized from commercially available basic materials using well known synthetic methods and without using expensive catalysts. Indoles of various designs were synthesized. They may be building blocks for the synthesis of biologically active substances, phthalocyanines of different structures having mesomorphic and catalytic properties. Compounds of this class of heterocycles were found among many natural products and they can be used as therapeutic agents, for example, as inhibitors of human lactate dehydrogenase of isoforms 5, selective inhibitors of monoamine oxidase A and B, and N-methoxyindole can be used to treat breast cancer. For citation:Chirkova Zh.V.

La crise économique comme architecte de l’espace public européen. Le cas des élections européennes françaises de 2014
Authors: Berdah Capucine , Désert Kim
Published: May 2017

En donnant plus de visibilité et un rôle politique accru à l’Union européenne, la crise permet de structurer un espace public au niveau européen. Une des façons de vérifier cette hypothèse est d’étudier le discours médiatique. Cet article analyse l’impact de la crise sur le discours médiatique français. Dans une démarche exploratoire, nous comparons les campagnes électorales des élections européennes de 2009 (avant la crise) et de 2014 (pendant la crise) afin d’observer s’il y a une évolution dans le traitement de l’information. Nos données suggèrent que la crise a un impact sur la visibilité de l’Union européenne en créant un espace médiatique et politique qui lui est propre, et qu’elle n’avait pas en 2009.
