Características de indicadores de desempenho em sistemas de incentivo do setor automotivo
Authors: Gonçalves Rosana Carmen de Meiroz Grillo , Tortoli Júlia Peres
Published: September 2015

Esta pesquisa visa obter respostas sobre quais indicadores de desempenho são utilizados pelas indústrias automotivas em seus sistemas de incentivo, ou seja, em seus acordos de participação nos lucros e resultados (PLR). Foram analisados 39 acordos de PLR, que tiveram seus indicadores de desempenho agrupados em seis classes: financeiros, qualidade, flexibilidade, produtividade, clientes e recursos humanos. Entre os resultados obtidos detectou-se a presença maciça de indicadores não-financeiros tradicionais, não tendo sido encontrados indicadores de desempenho mais voltados à inserção socioambiental da empresa, por exemplo, indicadores relacionados ao seu impacto ambiental. O predomínio de indicadores de produtividade e de qualidade remete à possibilidade do uso de indicadores não-financeiros como proxies de indicadores financeiros em ciclos econômicos em que há a expansão das atividades industriais. Após a exploração dos resultados, sugere-se que trabalhos futuros considerem o estudo da composição do grupo de indicadores juntamente com fatores que impactam a escolha dos indicadores, tais como posicionamento estratégico e sofisticação tecnológica.

Problema de roteamento em arcos capacitado e periódico aplicado a um contexto real
Authors: Batista Guilherme Vinicyus , Scarpin Cassius Tadeu
Published: September 2015

Um bom planejamento de inspeção e manutenção em ferrovias é essencial para garantir o fluxo dos trens e evitar possíveis acidentes. Essa inspeção deve ser feita periodicamente por veículos que transitam sobre os trilhos coletando dados e identificando falhas que precisam ser corrigidas. O objetivo desse artigo é apresentar uma modelagem matemática, baseada em programação linear binária, capaz de solucionar esse problema. Este problema é uma aplicação real do Problema de Roteamento em Arcos Capacitado e Periódico (PCARP). No PCARP cada um dos arcos de uma rede tem demandas periódicas ao longo de um horizonte de tempo bem definido, devendo ser criadas rotas para cada carro de modo que todas as necessidades sejam atendidas da melhor maneira possível sem exceder a capacidade dos carros. A aplicação proposta apresenta características diferenciadas das já apresentadas na literatura devido ao fato de não necessitar voltar a um depósito ao final de um dia e poder atrasar algum atendimento se necessário. O resultado obtido é satisfatório, atendendo as demandas com um movimento sincronizado dos veículos.
Reciprocity in Relationship Marketing: A Cross-Cultural Examination of the Effects of Equivalence and Immediacy on Relationship Quality and Satisfaction with Performance
Authors: Hoppner Jessica J. , Griffith David A. , White Ryan C.
Published: September 2015

Effective relationship marketing (RM) in a firm's global operations necessitates that the underlying aspect of reciprocity operate consistently across markets. Unfortunately, few studies have empirically examined the role of reciprocity in RM, let alone whether the effects of reciprocity in RM are universal across national cultures. To address these limitations, the authors examine reciprocity as a multidimensional norm whose dimensions of equivalence (what is exchanged) and immediacy (when the exchange occurs) influence relationship quality and satisfaction with performance in cross-border U.S.–Japanese interfirm relationships. The results indicate that the effects of reciprocity on relationship quality are conditional on national culture. Specifically, uncertainty avoidance positively moderates the positive effect of equivalence on relationship quality, while individualism and short-term orientation positively moderate the negative effect of immediacy on relationship quality. Moreover, a supplemental analysis indicates that the key mediating variable RM model may not hold across all cultures when predicting satisfaction with performance. These findings underscore the importance of adapting RM strategies across national cultures and provide managers with recommendations for developing high-quality cross-border buyer–seller relationships.

Combined heterogeneous metal/organic catalysts for eco-friendly synthesis
Authors: Córdova Armando
Published: September 2015

The interplay and synergistic cooperation between homogeneous and heterogeneous catalyst systems is of utmost importance in nature. It is also applied in chemical synthesis. Here, it can allow for new reactivity, which is not possible by the employment of a single catalyst, and promote the catalysis of multiple transformations in a one-pot sequence. This could overall lead to novel reactions and the development of sustainable chemistry. In this context, a versatile and broad synergistic strategy for the selective synthesis of valuable molecules with variable complexity and under eco-friendly conditions is disclosed. It is based on integrated heterogeneous metal/organo multiple relay catalysis, which is performed in a single reaction vessel, and allows for the assembly of complex molecules (e.g., heterocycles and carbocycles) with up to three quaternary stereocenters in a highly enantioselective fashion from simple alcohols and air/O2.
Ultrasensitive estrogen levels at 7 years of age predict earlier thelarche: evidence from girls of the growth and obesity Chilean cohort
Authors: Pereira Ana , Corvalán Camila , Uauy Ricardo , Klein Karen O , Mericq Verónica
Published: September 2015

Objective

Prepubertal estradiol equivalents have been inconsistently linked to age at thelarche; elucidating this relationship becomes relevant given the worldwide decline in the age of puberty onset. Thus, our aim is to assess whether prepubertal girls with higher serum levels of estradiol equivalents at age 7 have a greater risk of presenting early thelarche (ET).

Design

Nested case–control study within the Growth and Obesity Cohort Study of 1196 low-middle income children (∼50% girls) from Santiago, Chile. Girls were defined as cases (ET; n=61) if breast bud appeared prior to 8 years of age; controls (n=91) had thelarche >8 years.

Methods

At 6.7 years, weight, height and waist circumference were measured and a fasting blood sample was obtained for measuring estrogen equivalent (ultrasensitive recombinant cell bioassay), DHEAS, leptin, insulin and IGF1. Beginning at 7 years old, Tanner staging was assessed prospectively twice a year and the appearance of breast bud was assessed by palpation.

Results

Mean serum estradiol-equivalent at 6.7 years was 3.9±3.6 pg/ml for cases and 3.6±2.3 pg/ml for controls. Girls with ET had a higher risk of presenting elevated estradiol-equivalent (≥5 pg/ml) at 7 years (OR=2.05, 95% CI: 0.96–4.36) than controls that was borderline significant. However, after adjusting by BMI, insulin and IGF1 at age 7, the association between estradiol-equivalent and ET was significant (OR=2.29 (95% CI: 1.05–5.01)).

Conclusions

Chilean girls from low to middle socioeconomic status with ET exhibited double the risk of having high levels of estradiol-equivalent at 7 years than girls with a later age of thelarche. Whole-body adiposity and increased adrenal activity did not explain the observed prepubertal estrogen increase.
Professionally Responsible Disclosure of Genomic Sequencing Results in Pediatric Practice
Authors: McCullough Laurence B. , Brothers Kyle B. , Chung Wendy K. , Joffe Steven , Koenig Barbara A. , Wilfond Benjamin , Yu Joon-Ho
Published: September 2015

Genomic sequencing is being rapidly introduced into pediatric clinical practice. The results of sequencing are distinctive for their complexity and subsequent challenges of interpretation for generalist and specialist pediatricians, parents, and patients. Pediatricians therefore need to prepare for the professionally responsible disclosure of sequencing results to parents and patients and guidance of parents and patients in the interpretation and use of these results, including managing uncertain data. This article provides an ethical framework to guide and evaluate the professionally responsible disclosure of the results of genomic sequencing in pediatric practice. The ethical framework comprises 3 core concepts of pediatric ethics: the best interests of the child standard, parental surrogate decision-making, and pediatric assent. When recommending sequencing, pediatricians should explain the nature of the proposed test, its scope and complexity, the categories of results, and the concept of a secondary or incidental finding. Pediatricians should obtain the informed permission of parents and the assent of mature adolescents about the scope of sequencing to be performed and the return of results.

Systemfremde Steuerungen in modulare Anlagen integrieren
Authors: Pfeffer Annett , Hahn Anna , Obst Michael , Urbas Leon
Published: September 2015

Um die Wettbewerbsfähigkeit in der Prozessindustrie zu erhalten, wird verstärkt an modularisierten, verfahrenstechnischen Anlagen geforscht. Während der verfahrenstechnische Teil der Module nur abhängig von der bereitzustellenden verfahrenstechnischen Funktion ist, muss die Automatisierungstechnik der Module in ein übergeordnetes Leitsystem integriert werden. Derzeit funktioniert diese Integration vor allem manuell und mit systemeigenen Steuerungen. Ziel ist es, dass bereits automatisierte Module nicht mehrfach manuell für die Prozessleitsysteme (PLS) konfiguriert werden müssen, sondern dass sich auch Module mit systemfremden Steuerungen weitgehend automatisch integrieren lassen. Im Kontext der Modularisierung nach NE 148 entspricht dies dem Anwendungsfall des integrierbaren Moduls mit eigener Steuerung. Im Beitrag wird der Ansatz zur Nutzung existierender Beschreibungsmittel aufgegriffen. Am Beispiel des Prozessleitsystems PCS 7 werden Wege aufgezeigt, wie bereits heute systemfremde Steuerungen automatisch in ein übergeordnetes PLS integriert werden können und wo zusätzliche Schnittstellen benötigt werden.

Resumo: Este trabalho propõe-se a apresentar a problemática que envolve a disciplina de Filosofia da Educação no Brasil, abordando primeiramente, de um lado, como a Filosofia em si mesma chega em terras brasileiras como parte do programa colonizador português e, de outro lado, como a Educação foi tratada em nosso país desde os seus primórdios, cujos elementos problemáticos são cruzados com aqueles observados no primeiro caso. Nesse sentido, entende-se a Filosofia da Educação como um campo conflituoso em razão dessas forças que atravessam o seu campo de atuação. Por conseguinte, são estabelecidas algumas medidas de enfrentamento dessa situação, como sugestão do estudo, apontando para a necessidade de a disciplina acompanhar o seu próprio trabalho com a atenção merecida, no sentido de desnudar e minimizar as dificuldades de sua prática pedagógica e enquanto proposta disciplinar oferecida no contexto de formação de professores.

Abstract: This study aims to present a problem involving the discipline of Philosophy of Education in Brazil, first addressing, in the one hand, how the philosophy itself arrives in Brazilian lands as part of the Portuguese colonizer program, and on the other hand, how Education was treated in our country since its origin, whose problematic elements are crossed with those observed in the first case. In this sense, Philosophy of Education has been understood as a conflicting field due to these forces that is crossing its field. Therefore, there are some measures that are established for dealing with this situation, as suggestions from this study, pointing to the need for the discipline to monitories their own work with the attention it deserves, in the sense of stripping and minimize the difficulties of their teaching and the discipline proposal to be offer in the context of the teacher’s training.

The Key Role of Nurse Researchers in the Evaluation of Nurse Practitioner Models of Practice
Authors: Hungerford Catherine , Prosser Brenton , Davey Rachel
Published: September 2015

The Nurse Practitioner–Aged Care Models of Practice Program involved diverse models of practice comprising multiple stakeholders located in more than 30 locations across Australia, in remote, rural, urban, and metropolitan settings. Funded by the Australian government, the aims of the program included supporting development of effective, economically viable, and sustainable aged care nurse practitioner models of practice; and enabling improvements in access to primary health care for people aged older than 65 years.

This article describes the process by which a framework was developed to support the evaluation of this program. A particular challenge for the nurse researchers involved in the evaluation was to ensure the unique values of the nursing profession were upheld alongside economic, biomedical, and empirical imperatives in the diverse processes involved in collecting and interpreting data. The evaluation framework developed provides an important means of enabling research teams who undertake complex evaluations of diverse nursing models of practice to maintain a common goal—to unify the various stakeholders involved, while at the same time upholding what is most important to the profession of nursing. This article highlights how nurses can play an influential role when involved in the multidisciplinary evaluation of new and innovative approaches to practice.
Development of E‐chromosome Specific Molecular Markers for Thinopyrum elongatum in a Wheat Background
Authors: Chen Shiqiang , Gao Yong , Zhu Xue , Zhang Chao , Cao Wenguang , Fedak George , He Zhentian , Chen Xiulan , Chen Jianmin
Published: September 2015

Eleven primers were synthesized according to the reverse transcriptase and long terminal repeat (LTR) conserved regions of retrotransposons BARE‐1 from barley (Hordeum vulgare L.) and RIRE‐1 from rice (Oryza sativa L.). Fifty‐two pairs of primer combinations based on these 11 primers were used for DNA amplification of Chinese Spring‐Thinopyrum elongatum addition lines, substitution lines plus the two parents. It showed that 145 specific fragments of inter‐simple sequence repeat (ISSR), inter‐retrotransposon amplified polymorphism (IRAP), and retrotransposon microsatellite amplified polymorphism (REMAP) were obtained which distributed over all the seven E‐genome chromosomes of Th. elongatum. Sixty specific fragments of ISSR, IRAP, and REMAP were randomly selected for cloning and sequencing. Thirty‐four sequences were found not to be homologous with wheat (Triticum aestivum L.) sequences in GenBank, which were considered to be the specific sequences of Th. elongatum. Thirty‐four pairs of primers based on these 34 specific sequences were synthesized, and 13 chromosome‐specific markers of Th. elongatum were identified and converted into SCAR markers. The results indicated that ISSR, IRAP, and REMAP techniques can be used to develop chromosome‐specific sequence‐characterized amplified regions (SCAR) markers with good stability and repeatability. These specific SCAR markers can now be used to detect Th. elongatum chromosomes and possibly even some introgressed segments in a wheat background.

Study of the floristic composition of fir-spruce-beech forests in Serbia and Bosnia-Herzegovina
Authors: Eremija Sasa , Cvjeticanin Rade , Novakovic-Vukovic Marijana , Rakonjac Ljubinko , Lucic Aleksandar , Stajic Snezana , Miletic Zoran
Published: September 2015

The mixed forest of fir, spruce, and beech (Piceo-Abietetum Colic 1965) is an
important and widespread plant community on the Balkan Peninsula. Within the
Dinarides, it occupies the upper zone of the beech-fir forest belt,
establishing a regional belt of vegetation in the Illyrian province. This
community occupies significant areas in western and southwestern Serbia where
it also creates a regional belt, thus confirming that this part of Serbia
belongs to the Illyrian floral-geographical province. This paper compares the
floristic composition of the fir-spruce-beech forests in Serbia and
Bosnia-Herzegovina in order to determine the differences between the study
stands. A total of 29 relev?s were analyzed, 17 from the mountain of Lisina
(Bosnia-Herzegovina) and 12 from the Pester plateau (Serbia). Cluster
analysis revealed a clear differentiation between the study stands and
species in Bosnia-Herzegovina and those in Serbia. The main difference is in
the dominant species: Fagus moesiaca (K. Maly) Czecz. in Serbia and Fagus
sylvatica L. in Bosnia-Herzegovina. In Bosnia-Herzegovina, the forest grows
under conditions of a uniform, maritime and humid climate, while in Serbia it
grows under conditions of a continental climate with less rainfall and a
strong zoo-anthropogenic impact. Regarding the spectrum of life forms, there
are more phanerophytes and geophytes in Bosnia-Herzegovina than in Serbia. On
the other hand, the spectrum of floral elements in Serbia is richer in
xerophilous, Balkan and sub-Mediterranean floral elements.
Real Earnings Management and Long-Term Operating Performance: The Role of Reversals in Discretionary Investment Cuts
Authors: Vorst Patrick
Published: September 2015

I examine whether a reversal of an abnormal cut in discretionary investments is associated with the degree to which the cut is reflective of real earnings management (REM) and whether and how it predicts future operating performance. I define a reversal as occurring when a firm cuts discretionary investments to a below-expected level in one period and reverts back to at least the expected level of investment during the next period. Unlike accrual earnings management, REM involves deliberately altering the operations of the firm to influence reported accounting numbers. To the extent that such interventions diverge from optimality, they can expose the firm to real economic costs. I find that a reversal of an abnormal cut in discretionary investments in the year after the cut has taken place is indicative of REM. I further find that, on average, reversing cuts are associated with lower future operating performance, but that such results vary significantly depending on the various incentives to engage in REM, as well as other factors that affect its associated costs and benefits. These findings are of interest to investors, regulators, and academics with respect to the identification and consequences of REM.

Cathelicidin antimicrobial peptide (CAMP) is a naturally occurring secreted peptide that is expressed in several organs with pleiotropic roles in immunomodulation, wound healing, and cell growth. We previously demonstrated that gut Camp expression is upregulated when type 1 diabetes–prone rats are protected from diabetes development. Unexpectedly, we have also identified novel CAMP expression in the pancreatic β-cells of rats, mice, and humans. CAMP was present even in sterile rat embryo islets, germ-free adult rat islets, and neogenic tubular complexes. Camp gene expression was downregulated in young BBdp rat islets before the onset of insulitis compared with control BBc rats. CAMP treatment of dispersed islets resulted in a significant increase in intracellular calcium mobilization, an effect that was both delayed and blunted in the absence of extracellular calcium. Additionally, CAMP treatment promoted insulin and glucagon secretion from isolated rat islets. Thus, CAMP is a promoter of islet paracrine signaling that enhances islet function and glucoregulation. Finally, daily treatment with the CAMP/LL-37 peptide in vivo in BBdp rats resulted in enhanced β-cell neogenesis and upregulation of potentially beneficial gut microbes. In particular, CAMP/LL-37 treatment shifted the abundance of specific bacterial populations, mitigating the gut dysbiosis observed in the BBdp rat. Taken together, these findings indicate a novel functional role for CAMP/LL-37 in islet biology and modification of gut microbiota.

OBJECTIVE

Relative to European Americans, African Americans manifest lower levels of computed tomography–based calcified atherosclerotic plaque (CP), a measure of subclinical cardiovascular disease (CVD). Potential relationships between CP and cerebral structure are poorly defined in the African American population. We assessed associations among glycemic control, inflammation, and CP with cerebral structure on MRI and with cognitive performance in 268 high-risk African Americans with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Associations among hemoglobin A1c (HbA1c), C-reactive protein (CRP), and CP in coronary arteries, carotid arteries, and the aorta with MRI volumetric analysis (white matter volume, gray matter volume [GMV], cerebrospinal fluid volume, and white matter lesion volume) were assessed using generalized linear models adjusted for age, sex, African ancestry proportion, smoking, BMI, use of statins, HbA1c, hypertension, and prior CVD.

RESULTS

Participants were 63.4% female with mean (SD) age of 59.8 years (9.2), diabetes duration of 14.5 years (7.6), HbA1c of 7.95% (1.9), estimated glomerular filtration rate of 86.6 mL/min/1.73 m2 (24.6), and coronary artery CP mass score of 215 mg (502). In fully adjusted models, GMV was inversely associated with coronary artery CP (parameter estimate [β] −0.47 [SE 0.15], P = 0.002; carotid artery CP (β −1.92 [SE 0.62], P = 0.002; and aorta CP [β −0.10 [SE 0.03] P = 0.002), whereas HbA1c and CRP did not associate with cerebral volumes. Coronary artery CP also associated with poorer global cognitive function on the Montreal Cognitive Assessment.

CONCLUSIONS

Subclinical atherosclerosis was associated with smaller GMV and poorer cognitive performance in African Americans with diabetes. Cardioprotective strategies could preserve GMV and cognitive function in high-risk African Americans with diabetes.
Distal Rectal Skip-Segment Hirschsprung Disease and the Potential for False-Negative Diagnosis
Authors: Coe Alexander , Avansino Jeffrey R. , Kapur Raj P.
Published: September 2015

In skip-segment Hirschsprung disease (SS-HSCR), an aganglionic segment of bowel, which extends proximally from the distal rectum, is interrupted by a ganglionated “skip segment.” Skip segments are usually located far proximal to the rectum where they do not interfere with initial diagnosis, although the possibility of distal SS-HSCR should be considered during interpretation of intraoperative biopsies or patients with atypical postoperative courses. We report 2 cases of SS-HSCR with skip areas in the distal rectum, 1 of which led to a false-negative diagnosis by suction rectal biopsy. These 2 cases of SS-HSCR, along with others in the literature, highlight the point that ganglionic skip segments can confuse clinicians and lead to inadequate bowel resection, diagnostic delay, or a false-negative diagnosis. The pathogenesis of SS-HSCR is discussed in light of recent discoveries regarding transmesenteric migration of vagal neural crest cells and the role of sacral neural crest cells in hindgut neurodevelopment.

Background and Aims: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease in children. The aim of this study was to identify various cardiac defects associated with TOF by transthoracic echocardiography.Methods: All children presenting to Shahid Gangalal National Heart Centre, with the diagnosis of TOF from 2014 to 2015 were included in the study. Echocardiograpic reports of all eighty eight children were reviewed.Results: The mean age of presentation was 3.5 } 3.9 years. Fifty six (64%) children were male and thirty two (36%) were female. Pulmonary artery anomaly was found in nine (10.2%) children which included hypoplastic pulmonary arteries, absent left pulmonary artery, post stenotic and aneurysmal dilatation of pulmonary artery. Pulmonary valve anomalies were seen in 13(14.8%) children which include pulmonary atresia, pin-hole opening of valve and bicuspid and absent pulmonary valve. Double outlet right ventricle, patent ductus arteriosus/major aortico-pulmonary collaterals, atrial septal defect and persistent left superior venacava were present in 12 (13.6%), 21 (23.9%), 22 (22.7%) and nine (10.2%) respectively. Right sided aortic arch was seen in 20 (22.7%).Conclusion: TOF is associated with various anatomical variations which need to be identified to avoid surgical complications. These can be diagnosed by echocardiography which has greatly reduced the need for invasive cardiac catheterization for these patients.Nepalese Heart Journal 2015;12(2):65-68

Authors: Jayaprasad N , Madhavan Suresh
Published: September 2015

Pheochromocytomas are rare neuro-endocrine tumors arising from chromaffin cells of the sympathetic nervous system.Pheochromocytomacan have diverse clinical presentations, which makes the diagnosis often difficult. We present a case of adrenalpheochromocytoma presenting as acute ST elevation myocardial infarction (STEMI). Catecholamine surge in patients with pheochromocytoma can cause myocardial infarction in the absence of atherosclerotic coronary artery disease. Pheochromocytoma presenting as acute myocardial infarction is very rare and it occurs in young individuals. This is a rare case report of pheochromocytoma in an elderly male presenting with acute STEMI successfully treated by resection of tumor.Nepalese Heart Journal 2015;12(2):89-92
A comparative study of nanostructured calcium copper titanate thin film and powder and their properties

Published: September 2015

This paper reports on the effect of phase formation on the dielectric behaviour of nanostructured calcium copper titanate (CaCu3Ti4O12) thin film and powder prepared by using the sol–gel method. X-ray diffraction peaks were indexed as a cubic phase belonging to the Im3 space group for both film and powder. The monophase with a highly crystalline nature was obtained at lower temperature for thin film compared with powder. Micrographs of CaCu3Ti4O12 thin film and nanopowder confirmed the presence of nano-dimensional particles. The functional groups and optical properties of both film and powder were characterized by using the Fourier transform infrared spectrum and the photoluminescence spectrum. The CaCu3Ti4O12 thin film showed higher dielectric permittivity than powder, which strongly suggests that nanostructured thin film is a more efficient material than powder for microelectronic devices.

Published: September 2015

Potato starch-based carbon particles were prepared by low-temperature carbonization in methyl silicone oil at 220 °C for 15 h and subsequent carbonization at 600 °C for 1 hour under nitrogen. The as-prepared carbon particles were molded, and then heat-treated. The results confirmed that carbon particles could keep the original shape of the potato starch and exhibit high monodispersity with smooth surfaces. The size distribution of carbon particles ranged from 10 to 100 μm and the blocks molded from the carbon particles exhibited relatively superior mechanical strength with a flexural strength of 85.7 MPa. Additionally, it was found that the low-temperature carbonization in oil is crucial in the preparation of this kind of carbon particle.

Published: September 2015

DNA fragment assembly represents an important challenge to the development of efficient and practical algorithms due to the large number of elements to be assembled. In this study, we present some graph theoretical linear time algorithms to solve the problem. To achieve linear time complexity, a heap with constant time operations was developed, for the special case where the edge weights are integers and do not depend on the problem size. The experiments presented show that modified classical graph theoretical algorithms can solve the DNA fragment assembly problem efficiently.

Published: September 2015

Long non-coding RNAs (lncRNAs) are larger than 200 nucleotides in length and pervasively expressed across the genome. An increasing number of studies indicate that lncRNA transcripts play integral regulatory roles in cellular growth, division, differentiation and apoptosis. Deregulated lncRNAs have been observed in a variety of human cancers, including hepatocellular carcinoma (HCC). We determined the expression profiles of 90 lncRNAs for 65 paired HCC tumor and adjacent non-tumor tissues, and 55 lncRNAs were expressed in over 90% of samples. Eight lncRNAs were significantly down-regulated in HCC tumor compared to non-tumor tissues (p < 0.05), but no lncRNA achieved statistical significance after Bonferroni correction for multiple comparisons. Within tumor tissues, carrying more aberrant lncRNAs (6–7) was associated with a borderline significant reduction Cancers 2015, 7 1848 in survival (HR = 8.5, 95% CI: 1.0–72.5). The predictive accuracy depicted by the AUC was 0.93 for HCC survival when using seven deregulated lncRNAs (likelihood ratio test p = 0.001), which was similar to that combining the seven lncRNAs with tumor size and treatment (AUC = 0.96, sensitivity = 87%, specificity = 87%). These data suggest the potential association of deregulated lncRNAs with hepatocarcinogenesis and HCC survival.
Nephron Patterning: Lessons from Xenopus, Zebrafish, and Mouse Studies
Authors: Desgrange Audrey , Cereghini Silvia
Published: September 2015

The nephron is the basic structural and functional unit of the vertebrate kidney. To ensure kidney functions, the nephrons possess a highly segmental organization where each segment is specialized for the secretion and reabsorption of particular solutes. During embryogenesis, nephron progenitors undergo a mesenchymal-to-epithelial transition (MET) and acquire different segment-specific cell fates along the proximo-distal axis of the nephron. Even if the morphological changes occurring during nephrogenesis are characterized, the regulatory networks driving nephron segmentation are still poorly understood. Interestingly, several studies have shown that the pronephric nephrons in Xenopus and zebrafish are segmented in a similar fashion as the mouse metanephric nephrons. Here we review functional and molecular aspects of nephron segmentation with a particular interest on the signaling molecules and transcription factors recently implicated in kidney development in these three different vertebrate model organisms. A complete understanding of the mechanisms underlying nephrogenesis in different model organisms will provide novel insights on the etiology of several human renal diseases.

Published: September 2015

The photocatalyst composite coatings on alumina (Al2O3) balls had been prepared by mechanical coating technique (MCT) with titanium (Ti) powder, adding a certain content of chromium (Cr) powder and a subsequent oxidation process. The effect of oxidation conditions and adding Cr on the composite coatings of chromium-titanium dioxide (Cr-TiO2) was investigated. The results show Cr-TiO2 coatings are with mixed-phase of anatase and rutile under different oxidation conditions, and the mass fraction of the rutile phase (XR) has been obviously increased when under 973 K. The SEM images indicate that adding Cr could significantly accelerate the growth of surface structures, especially at 1073 K. The photocatalytic activity of Cr-TiO2 coatings firstly increases, then decreases, with the addition of Cr. Compared with that of two other oxidation conditions, the enhancement on photocatalytic activity by adding Cr under visible light is relatively higher, especially at 973 K for 10 h.
