Published: February 2020

Background: The global prevalent ptxP3 strains varies from about 10% to about 50% of circulating B. pertussis population in different areas of China. Methods To investigate the difference of vaccination status between different genotypes in the circulating B. pertussis after 10 years of acellular pertussis vaccine (aPV) used in China. The nasopharyngeal swabs and isolates of B. pertussis from these patients were used to perform genotyping of antigen genes. We use antibiotic susceptibility test against erythromycin and sequencing methods for site 2047 of 23S rRNA to determine the resistance status. Results The ptxP1 allele with erythromycin resistant strains infection (total of 449 samples) consisted of 84.70% to 96.70% from 2012 to 2016. Only 2 of the 21 ptxP3 strains infected in children vaccinated with co-purified aPV, that showed a significant difference between the ptxP1 strains does (χ 2 =6.87, P=0.032). Conclusions The ptxP1 allele with erythromycin resistant B. pertussis was steadily increased in Xi’an, China from 2012 to 2016, where co-purified aPV was prevalence used . We assumed that the co-purified aPV might protect against ptxP3 strains more efficient, which generated a rare chance for ptxP3 strains to be under the antibiotic pressure and further developed to be erythromycin resistance. A further cohort study and the mechanisms of the additional antigen proteins of co-purified aPV protected against B. pertussis should be consideration.

Published: February 2020

Background: Pseudoangiosarcomatous squamous cell carcinoma, also called pseudovascular, pseudoangiomatoid or adenoid pseudovascular carcinoma, is an uncommon and highly aggressive variant of squamous cell carcinoma. Histologically, it is characterized by proliferation of atypical keratinocytes with acantholysis and formation of pseudovascular spaces, forming anastomosed channels lined with neoplastic cells that invade the dermis. These cells are positive for cytokeratin and vimentin and negative for vascular markers such as CD31 and CD34. There are few reports of this tumor variant in the literature. Skin, breast, lung and vulva involvement have been described. But to the best of our knowledge, no cases involving the penis have been described. This article aims to describe the first case of angiosarcomatous squamous cell carcinoma of the penis. Case Report: The patient presented with a painful lesion in the penis associated with urinary retention. Macroscopic findings exhibited an ulcerative vegetating lesion that involving the entire glans and part of the penile body, as well as infiltration of penile structures and scrotal skin. Microscopy shows atypical proliferation of sarcomatous keratinocyte pattern mimicking vascular spaces. These neoplastic squamous cells were positive for the cytokeratin marker and were negative for the CD31 and CD34 markers. Human papilloma virus biomarkers, p16, E6 protein and PCR, were all negative. Conclusion: This report presents the first reported case of penile pseudoangiosarcomatous squamous cell carcinoma, as an important differential diagnosis.
Risk of Bacterial Infection in Acquired Complement Deficiencies
Authors: Al-Shaikhly Taha , Hayward Kristen , Basiaga Matthew L , Allenspach Eric J
Published: February 2020

Background: Acquired complement deficiency can occur in the setting of autoimmune syndromes, such as systemic lupus erythematosus (SLE), with very low or, occasionally, undetectable C3 levels. Based on data from patients with inherited complement defects, a perceived risk for serious bacterial infection exists amongst patients with transiently low complement, but the degree of risk related to C3 level is unknown. Methods: We performed a retrospective study of all pediatric patients with an undetectable total complement activity or absent individual complement components measured at our institution from 2002 to 2018. We assessed annual rate of serious bacterial infection (SBI) defined as requiring hospitalization and/or parenteral antibiotics. Among included SLE patients, we assessed the 30-day probability of SBI for given C3 measurements using a logistic regression model to determine risk. Results: Acquired complement deficiency secondary to SLE-related disease [n=44] was the most common underlying diagnosis associated with depressed complement levels. While controlling for immunosuppression level and lupus nephritis diagnosis, our logistic regression analysis of pediatric patients with SLE showed low C3 level was temporally associated with having an SBI event. Even in patients with equivalent immunosuppression, patients with an SBI were found to have lower C3 levels preceding the infection relative to patients without SBI. Conclusion: Pediatric patients with the diagnosis of SLE can develop very low C3 levels that are independently associated with risk of serious bacterial infection. Patients prone to complement consumption may particularly be at risk.

Published: February 2020

Background People with a migration background are a vulnerable group regarding dementia. Providing care for this group is a public health challenge in Europe. Many countries are issuing care guidelines, but a systematic overview of their references to migration is lacking. This study aims to determine the extent to which care guidelines take people with a migration background into account, which migration-related content focuses are set and to what extent specific actions are considered or recommendations are made to ensure their care. Methods This study is a systematic analysis of national dementia care guidelines of the EU and EFTA (European Free Trade Association) countries. Using the discourse analysis model by Rainer Keller (2011), n=43 documents from n= 24 EU and n=3 EFTA countries were systematically screened for migration references via keyword and context analysis. The content of the migration-related section was paraphrased, memos and comments were added and the individual text passages were coded using the strategy of open coding. Results 27 of the 35 EU- and EFTA countries have guidelines or similar documents on care for people with dementia and twelve refer to migration. Norway, Sweden, and Northern Ireland refer to this topic in detail. The focus of the migration-related documents is on the early detection and diagnosis of dementia. The main message is that standardized diagnostic tools such as the Mini-Mental State Examination (MMSE) or the clock test are not suitable for linguistic minorities. Nine countries make recommendations for the care of people with a migration background and dementia but only Norway, Sweden, and Denmark point to available healthcare services. A key recommendation is that the linguistic and cultural background of people should be taken into account when selecting diagnostic tests. Several countries refer to the validity of the RUDAS (Rowland Universal Dementia Assessment Scale) for migrants. Conclusions The topic of migration plays a subordinate role in the care guidelines of European countries. Almost all countries lack appropriate diagnostic tools and healthcare services for people with a migration background. Consequently, people with a migration background are a risk group for underdiagnosis and a lower level of care.

Published: February 2020

Background Anterior cruciate ligament (ACL) reconstruction is a common orthopaedic procedure. We developed a novel, low dose computed tomography (LDCT) protocol to assess tunnel position post-operatively. The effective radiation dose of this protocol is <0.5mSv, which is significantly less than the 2mSv dose for a conventional CT protocol. The aim of this study was to assess the accuracy of the LDCT protocol for determining tunnel position. Methods Twenty-six patients who underwent primary ACL reconstruction were included in the study. A LDCT scan was performed six weeks post-operatively. Femoral and tibial tunnel positions were measured on three dimensional (3D) reconstructions using previously validated techniques. Measurements were performed independently by three observers at two time points, four weeks apart. Results There was excellent intra- and inter-rater reliability for all measurements using the images obtained from the LDCT protocol. Intra-class correlation coefficient (ICC) values were >0.9 for all measurements. Conclusions The LDCT protocol described in this study accurately demonstrates femoral and tibial tunnels post ACL reconstruction, while exposing the patient to a quarter of the radiation dose of a conventional CT. This protocol could be used by orthopaedic surgeons for routine post-operative imaging, in place of plain film radiographs.

Published: February 2020

BACKGROUND Rickettsia spp. are human pathogens that cause a number of diseases and are transmitted by arthropods, including ixodid ticks. Estonia contributes a region, where the distribution area of two exophilic tick species of known medical importance, Ixodes persulcatus and I. ricinus, overlap. The presence of the nidicolous rodent-associated I. trianguliceps has recently been shown for Estonia. Although there is no Estonian data available on human disease caused by tick-borne Rickettsia spp., the presence of three Rickettsia species in non-nidicolous ticks, albiet at very dissimilar rates, was also previously reported. The aim of this studywas to screen, identify and characterize Rickettsia species in nidicolous and non-nidicolous ticks attached to rodents. RESULTS Nymphs and larvae of I. ricinus ( n = 1004), I . persulcatus ( n = 75) and I. trianguliceps ( n = 117) attached to rodents and shrews caught in different parts of Estonia were studied for the presence of Rickettsia spp. by nested PCR. Ticks were removed from 314 small animals of 5 species (bank voles Myodes glareolus , yellow necked mice Apodemus flavicollis , striped field mice A. agrarius, pine voles M. subterranius and common shrews S. araneus) . Rickettsial DNA was detected in 8,7% (103/1186) studied ticks. In addition to R. helvetica, previously found in questing ticks, this study reports the first identification of the recently described I. trianguliceps- associated Candidatus R. uralica in west of the Ural.
Down-regulation of NOX4 expression in dorsal root ganglion of spinal cord could alleviate cancer induced bone pain in rats by reducing oxidative stress response
Authors: Long Hao , Zheng Hui , Ai Long , Osman Kamil , Liu Zhigang
Published: February 2020

Background Cancer-induced bone pain (CIBP) is a common complication in many patients with malignant tumors, and seriously affects their quality of life. Recent studies have implicated reactive oxygen species (ROS) in the perception and regulation of pain through the spinal cord, indicating their possible involvement in CIBP as well. NADPH oxidases (NOX) generate ROS such as H2O2, superoxide anion, nitric oxide etc. as byproducts of oxidative phosphorylation. In this study, we will analyze the expression levels of NOX4 and its mechanism of action in CIBP. Material and Methods A CIBP model was established in rats and NOX4 was knocked down in the dorsal root ganglia via intrathecal injection of specific lentivirus. The downstream effects of NOX4 knockdown were analyzed by RT-PCR, immunofluorescence and Western blotting. Results NOX4 was significantly upregulated in the rats with CIBP, and mainly localized in the microglia of the dorsal root ganglion of spinal cord. However, NOX4 knockdown alleviated CIBP by reducing oxidative stress and weakening spinal cord sensitization to pain. Conclusion Down-regulation of NOX4 in the dorsal root ganglion of spinal cord can alleviate CIBP by reducing oxidative stress.

Published: February 2020

Background: It has been identified that aortic annulus (AA) is not completely round in normal and stenotic aortic valves and some studies invesigated the eccentricity of AA by some modalities. Aims: To compare size of aortic valve annulus in different views via transesophageal (TEE) 3D echocardiography in patients without aortic stenosis (AS). Method: 31 patients underwent TEE3D without AS. Full-volume of aortic valve was saved by TEE in short and long-axis views in single beat. AA was measured in 3 planes: two orthogonal lines in short-axis plane(D1 & D2), sagittal(D3) and coronal(D4)planes ,diameter of left ventricular outflow tract 5-10 mm below AA was measured in sagittal and coronal views (D5 and D6) . Area and perimeter of AA were measured in short-axis plane in hing points of aortic cusps and the annulus according to area and perimeter was calculated. These different AA sizes were compared. Distance of left main (LM) and right coronary arteries (RCA) from adjacent aortic leaflets and length of left coronary cusp were measured. All measurements were done in mid-systole. Results: From, 31 patients(51.5% F), age 50.61 ±10.78, median Left Ventricular Ejection Fraction (LVEF) was 55%. AA in sagittal is smaller than coronal view, mean difference=1.97mm, P=0.002.D1 is smaller than D3, D2 is not different with D4. D perimeter is larger than D area and D sagittal, mean difference=0.7 and 0.9mm respectively, P<0.05 and smaller than D coronal, mean difference is 1 mm. The difference between D area and D3 is not significant. D3 and D4 are not significantly different with D5 and D6. D perimeter is not different with mean D1&D2 and D3&D4.Mean distance of LM ostium and RCA from adjacent aortic leaflets is 14.2±2.97 and15.25±3.60 mm respectively. Mean length of left coronary cusp is 12.75±2.1 mm. Conclusion: AA is not completely round in non stenotic aortic valves and is larger in coronal than sagittal view, D perimeter is not different with mean annulus in sagittal and coronal views.

Published: February 2020

Background: Cortisol concentration is measured in blood, urine, and saliva samples. It has been recently proven that cortisol could be also detected in hair samples. Cortisol measurements in different samples have their own individual characteristics and clinical utility. We aimed to investigate the correlation between hair cortisol concentration and standard cortisol measurements used in clinical practice. Methods: Fifty adult volunteers with a negative history of endocrine disorders were enrolled into the study. Morning serum cortisol (MSC), evening serum cortisol (ESC), evening free salivary cortisol (EFSC), urine free cortisol (UFC) and hair cortisol were analyzed in all participants. Eventually, 41 volunteers were included into the study, whose cortisol concentration in the 1 mg overnight dexamethason suppression test (1mgONDST) were <50 nmol/l, and cortisol levels in serum, saliva and urine were within reference ranges. Hair cortisol concentration (HCC) was performed for 20 mg of hair strands of the proximal 1 cm hair segments. Results: HCC ranged from 0.3036 to 2.65 nmol/l/mg, and the average value was 0.8125±0.4834 nmol/l/mg. No significant correlations were found between HCC and MSC (rho=0.04419, p=0.7838), HCC and ESC (rho=-0.2071, p=0.1938), HCC and EFSC (rho=0.1005, p=0.532), and HCC and UFC (rho = 0.1793, p = 0.262). Conclusions : This work is another step in the discussion on the application of HCC determinations in clinical practice. Our results have showed no correlations between HCC and single point cortisol assessment in blood, saliva and urine in patients with reference cortisol levels.

TV Live Reporting: a Pilot Study in Contrastive Genre Analysis
Authors: El-Zawawy Amr M
Published: February 2020

TV live reporting or otherwise on-the-spot reporting is a sub-genre of TV journalism, but it is characterized by liveness and immediacy. The present paper focuses on the sub-genre of live reporting from the point of view of genre analysis within a contrastive framework. It makes use of two corpora of live reporting videos in English and Arabic, and analyzes them, both electronically and manually, according to a modified version of Bhatia’s approach to genre analysis (1993; 2002; 2012). It was found that TV correspondents maximize the use of first person pronouns that reflect the fact that they are reporting from the scene. They likewise tend to use hyperboles (see Geis, 1987). They also create an atmosphere of excitement by starting their reports by rising intonation patterns, but later on either resort to level routine delivery or attempt to project a certain attitude through a falling tone. English or English-speaking correspondents follow a generic structure where a spatial, temporal or opinion-centered setting is provided first, then follows the detailed body of narrative then finally the recapitulation. Arab correspondents, in contrast, directly go to the specifics of their reports, leaving the listeners without any trace of an introduction, and likewise clinch their reports abruptly by addressing the presenters.

Published: February 2020

Os repositórios digitais surgiram como resposta à industrialização da comunicação científica, que dificulta o progresso científico devido ao caro acesso à literatura científica e à lentidão para publicar novos trabalhos. Impulsionados pelos movimentos de acesso livre, o número de repositórios digitais cresceu significativamente nos últimos anos. No entanto, sabe-se pouco sobre o uso dos repositórios, principalmente no Brasil. Este artigo apresenta um retrato do uso deles como fonte de informação pelos membros das universidades federais brasileiras. Uma pesquisa quantitativa e qualitativa foi realizada através da aplicação de questionário em 564 pessoas de 52 universidades federais brasileiras e 488 da Universidade Federal de Pernambuco (UFPE). Pelo conhecimento dos autores, este é o primeiro estudo com uma quantidade significativa de participantes (1.052), cujas respostas passaram por um rigoroso controle de qualidade, e o primeiro a considerar os graduandos. Descobriu-se dois perfis de usuários: graduação e pós-graduação, incluindo pesquisadores e professores. Os resultados experimentais revelam que 52,0% e 86,9% da graduação e da pós-graduação, respectivamente, usam os repositórios para algum propósito e 39,3% e 78,8%, respectivamente, os usam como forma de busca por conhecimento acadêmico. Os repositórios institucionais e de teses e dissertações são usados por 28,6% e 30,2% da graduação, respectivamente, e por 69,3% e 73,7% da pós-graduação. Descobriu-se que a área de Ciências Sociais Aplicadas (73,4%) e a região Sul do Brasil são as que possuem mais membros que usam repositórios. O estudo de caso da UFPE revela que o uso pelos graduandos (24,1%) e da pós-graduação (63,5%) é inferior à média nacional.

As impressões laborais vivenciadas no fazer docente, na experiência de conduzir um periódico científico eletrônico e na prática bibliotecária obtida no processo editorial no Sistema Eletrônico de Editoração de Revistas (SEER), aliadas à revisão de literatura, permitiram-nos produzir esta comunicação com o objetivo de apresentar as áreas de atuação do bibliotecário no mundo da editoração e as competências técnicas e comportamentais necessárias para tal. A presença do bibliotecário no mercado editorial tem sido percebida, principalmente, em periódicos científicos e em editoras comerciais e universitárias, mas de forma ainda muito modesta, são poucos os bibliotecários que atuam na editoração, o que pode ocorrer devido à falta de conhecimento por parte do mercado editorial das diversas competências que esse profissional desenvolve durante a graduação, as quais podem ser um diferencial para uma empresa/instituição editorial. Esse profissional pode atuar na análise de provas editoriais, na assessoria aos editores, autores e pareceristas, na consultoria e avaliação técnica de revista para inclusão em bases de dados, catalogação na fonte, conferência da terminologia e indexação, elaboração de diferentes relatórios relacionados aos periódicos, além de muitas outras áreas. Para isso, precisa desenvolver competências técnicas, tais como: conhecimento do fluxo editorial, de indexadores, diretórios e bases de dados; saber correlacionar a linguagem do autor com os vocabulários controlados existentes; ter capacidade de análise e síntese; conhecer softwares de design e artes gráficas; ter domínio de normalização, ferramentas para gerenciamento de referências e padronizações em publicações editoriais, entre outras tantas; além de competências comportamentais, a exemplo de: assertividade; autonomia; concentração; criatividade; diligência; dinamismo; imparcialidade; inteligência emocional; liderança; motivação; organização; proatividade; relacionamento interpessoal e senso estético.

Authors: Silva Julianne Teixeira e , Santos Jonathan Alves dos
Published: February 2020

A partir da década de 1990 uma nova corrente teórica arquivística, Records Continuum (RC), surge na Austrália. O despontar do RC se dá a partir da necessidade de compreender os padrões arquivísticos frente a nova realidade dos documentos digitais. Amplamente discutido no cenário internacional, o Records Continuum, vem influenciando uma série de instrumentos normativos internacionais. Entretanto, no Brasil esta corrente é pouco difundida e estudada. Neste trabalho são apresentados resultados parciais de pesquisas de caráter teórico epistemológico, decorrente de projeto de Iniciação Científica, intitulado: “Arquivística brasileira e o modelo australiano do Records Continuum: uma análise teórica”, desenvolvido pela Universidade Federal da Paraíba,  o qual tem como objetivo ampliar conhecimentos sobre o Records Continuum e fomentar subsídios para discussões dessa nova temática no seio do campo arquivístico no Brasil, especialmente com a premente necessidade em lidar com os documentos arquivísticos digitais.

ASSESSING CARBON SEQUESTRADED IN BRAZILIAN NORTHEASTERN BIOMES UNDER ENSO EVENTS
Authors: Nascimento Robson de Sousa , Brito José Ivaldo Barbosa de , Borges Valéria Peixoto
Published: February 2020

The goal of the present study it was to know the behavior of the Net Primary Production (NPP) in years that have occurred El Niño Southern Oscillation (ENSO) and during the temperature anomalies of the surface of the Sea (SST) in the Tropical Atlantic, that is Atlantic Dipole. The results showed that the Amazon Rainforest, Atlantic Forest, and the Cerrado were not enough affected by the occurrence of El Niño Southern Oscillation and Atlantic Dipole. However, the Caatinga biome has shown to be quite sensitive to these events and patterns, especially in years of occurrence of El Niño, which contributed to a reduction in NPP; while in years of El Niña and negative dipole, the NPP achieved the highest values. The amount of rainfall in the previous year to the El Niño Southern Oscillation episodes showed influence on the amount of carbon sequestered by biomes in the year of study.
A new lower bound for the smallest singular value
Authors: Doroslovacki Ksenija , Cvetkovic Ljiljana , Sanca Ernest
Published: February 2020

The aim of this paper is to obtain new lower bounds for the smallest singular
value for some special subclasses of nonsingularH-matrices. This is done in
two steps: first, unifying principle for deriving new upper bounds for the
norm 1 of the inverse of an arbitrary nonsingular H-matrix is presented, and
then, it is combined with some well-known upper bounds for the infinity norm
of the inverse. The importance and efficiency of the results are illustrated
by an example from ecological modelling, as well as on a type of large-scale
matrices posessing a block structure, arising in boundary value problems.

Authors: Mohamed Mohamed
Published: February 2020

Based on the extensions of Morgenstern family (Huang and Bairamov
extensions), the concomitants of different types of generalized order
statistics (gos) and dual generalized order statistics (dgos) are obtained.
Moreover, a unified approach to such models is derived. Information
properties such as Shannon entropy and Kullback-Leibler divergence for Huang
and Kotz extension are obtained.
Improved algorithms for computing the greatest right and left invariant Boolean matrices and their application
Authors: Stanimirovic Stefan , Stamenkovic Aleksandar , Ciric Miroslav
Published: February 2020

We define right and left invariant matrices as Boolean matrices that are
solutions to certain systems of matrix equations and inequalities over
additively idempotent semirings. We provide improved algorithms for
computing the greatest right and left invariant equivalence and quasi-order
matrices. The improvements are based on the usage of the well-known
partition refinement technique. Afterwards, we present the application of
right invariant matrices in the determinization of weighted automata over
additively idempotent, commutative and zero-divisor free semirings. In
particular, we provide improvements of the well-known determinization method
of weighted automata over tropical semirings given by Mohri [Computational
Linguistics 23 (2) (1997) 269-311].

Semicommutativity of rings by the way of idempotents
Authors: Kose Handan , Ungor Burcu , Harmanci Abdullah
Published: February 2020

In this paper, we focus on the semicommutative property of rings via
idempotent elements. In this direction, we introduce a class of rings,
so-called right e-semicommutative rings. The notion of right
e-semicommutative rings generalizes those of semicommutative rings,
e-symmetric rings and right e-reduced rings. We present examples of right
e-semicommutative rings that are neither semicommutative nor e-symmetric nor
right e-reduced. Some extensions of rings such as Dorroh extensions and some
subrings of matrix rings are investigated in terms of right
e-semicommutativity. We prove that if R is a right e-semicommutative clean
ring, then the corner ring eRe is clean.

The left, the right and the sequential topology on Boolean algebras
Authors: Kurilic Milos , Pavlovic Aleksandar
Published: February 2020

For the algebraic convergence ?s, which generates the well known sequential
topology ?s on a complete Boolean algebra B, we have ?s = ?ls ? ?li, where
the convergences ?ls and ?li are defined by ?ls(x) = {lim sup x}? and ?li(x)
= {lim inf x+}? (generalizing the convergence of sequences on the Alexandrov
cube and its dual). We consider the minimal topology Olsi extending the
(unique) sequential topologies O?s (left) and O?li (right) generated by the
convergences ?ls and ?li and establish a general hierarchy between all these
topologies and the corresponding a priori and a posteriori convergences. In
addition, we observe some special classes of algebras and, in particular,
show that in (?,2)-distributive algebras we have limOlsi = lim?s = ?s,
while the equality Olsi = ?s holds in all Maharam algebras. On the other
hand, in some collapsing algebras we have a maximal (possible) diversity.
Geodesic mappings of spaces with affine connnection onto generalized Ricci symmetric spaces
Authors: Berezovski V.E. , Mikes Josef , Rýparová Lenka
Published: February 2020

The presented work is devoted to study of the geodesic mappings of spaces
with affine connection onto generalized Ricci symmetric spaces. We obtained a
fundamental system for this problem in a form of a system of Cauchy type
equations in covariant derivatives depending on no more than 1/2 n2(n+1)+n real parameters. Analogous results are obtained for geodesic mappings of
manifolds with affine connection onto equiaffine generalized Ricci symmetric
spaces.
New generalizations for convex functions via conformable fractional integrals
Authors: Ekinci Alper , Eroğlu Nazlıcan
Published: February 2020

The main objective of this study is to obtain conformable analogs of some
inequalities and to examine some integral inequalities for functions whose
modulus of first derivatives are convex and concave. We obtain
generalizations including conformable fractional integrals by separating [a;
b] interval to s equal subintervals.
Ideal relatively uniform convergence with Korovkin and Voronovskaya types approximation theorems
Authors: Mohiuddine S.A. , Hazarika Bipan , Alghamdi Mohammed
Published: February 2020

We introduce the notion of ideally relative uniform convergence of sequences
of real valued functions. We then apply this notion to prove Korovkin-type
approximation theorem, and then construct an illustrative example by taking
(p,q)-Bernstein operators which proves that our Korovkin theorem is
stronger than its classical version as well as statistical relative uniform
convergence. The rate of ideal relatively uniform convergence of positive
linear operators by means of modulus of continuity is calculated. Finally,
the Voronovskaya-type approximation theorem is also investigated.
A case report of a hybrid procedure (visceral and partial aortic arch debranching) in the treatment of a challenging aneurysm of the thoracoabdominal aorta in the endovascular era
Authors: Sladojevic Milos , Koncar Igor , Zlatanovic Petar , Jovanovic Sanja , Davidovic Lazar
Published: February 2020

Introduction. This paper aimed to present a hybrid approach as a less invasive and acceptable treatment. Case outline. Because of respiratory failure, the patient was deemed at high risk for open repair. Standard thoracic endovascular aortic repair (TEVAR) was unfeasible, so the patient underwent the hybrid procedure ? partial aortic arch debranching at the first stage, followed by visceral debranching and endovascular exclusion of thoracic aortic aneurysm as a final procedure. The postoperative course was uneventful and the patient was discharged 10 days after TEVAR and visceral debranching. Conclusion. Staged hybrid procedure with combined debranching of the aortic arch and visceral arteries is feasible and should be considered as an alternative treatment option in patients with high-risk for open repair.
Influence of Plasma Parameters on Light Emission in GD-OES Analysis of Ni–Cu System
Authors: Nowak Wojciech J. , Wierzba Patrycja
Published: February 2020

In the present work, an effect of plasma-forming parameters on light emission during analysis by glow discharge optical emission spectrometry of Ni–Cu model alloys is studied. To evaluate the effects of plasma-forming parameters on light emission, argon pressure was varied in the range between 600 Pa and 1000 Pa under a constant power of 20 W. Moreover, a variation of power at 20 W and 30 W under a constant Ar pressure of 1000 Pa was investigated. An effect of the element content on light emission was found. Namely, for Cu, a monotonic, non-linear increase in measured light intensity with an increasing Cu content was found. Surprisingly, for pure Ni, a lower light intensity was measured as for Ni90–Cu10 (at.%). Possible reasons causing this was listed as: (i) possible effect of hydrogen, (ii) overlapping of lines for Cu and Ni and (iii) self-absorbing of Ni line at 341.574 nm.
