Authors: Ornelas Hicks Margarita , Sanín Aguirre Luz Helena , Díaz-Barriga Fernando , Reza López Sandra Alicia , Romieu Isabelle
Published: October 2021

El objetivo fue evaluar el riesgo de intoxicación con plomo en tres estratos (E1, E2 y E3) urbanos cercanos a una industria que operó por alrededor de 90 años. En cada estrato se se- leccionó una muestra aleatoria de madres en edad reproductiva así como de sus hijos con edades entre 1-5 años. Se obtuvieron muestras de sangre capilar de madres e hijos y se analizaron por voltametría. En cada vivienda muestreada se tomaron muestras de suelo, pintura, polvo y agua para su análisis por voltametría anódica. En forma adicional, se se- leccionaron escuelas preescolares, y se obtuvieron mues- tras de sangre de niños menores de 6 años. Los modelos predictivos se realizaron mediante regresión lineal simple y regresión múltiple. La evaluación se ejecutó con la metodolo- gía de evaluación de riesgo de la EPA (Environmental Protection Agency). De un total de 324 niños examinados, el rango de valores de plomo en sangre osciló entre 2.8-50.2 μg/dL con una media geométrica de 11.4 μg/dL (s±8.2), el 32% >10 μg/dL, 4% > 25 μg/dL, 1% > 45 μg/dL. Se encontró una zona de alto riesgo en E1 y de mediano riesgo en E2 (75% y 40% de niños con > 10 μg/dL; norma SSA). Las concentraciones de plomo presentaron una relación inversa con la distancia. Las muestras de suelo superficial mostraron un rango de 100 a > 9,000 ppm. Los valores de plomo en madres se encon- traron dentro de la norma. Los predictores de plomo en niños se relacionaron con la exposición a suelo, el cual aporta más del 90% como fuente de exposición. Se concluye que existe una contaminación residual en la zona aledaña a la fundidora, la cual debe remediarse antes de seguir realizando activida- des recreativas y culturales.

The research was intended to describe the use of Simalungun taboo words across times in Simalungun (1930-2021). The language of Simalungun is spoken by people living outside the district of Simalungun, North of Sumatera and other people. This research was carried out in a multi-case descriptive qualitative design. Descriptual qualitative research design was defined as a social science research approach that emphasised the collection, use of inductive thinking and understanding of descriptive data in natural environments. While multi case is defined as a study which is using two or more subjects, settings, or depositories of data (Bogdan & Biklen, 1982). Documentation, interviews and observations of participants were used to collect data on linguistic taboos. The data sources were collected from 45 informants of different ages (1930-2021) and sexes who reside in Pematangsiantar, Pematangraya and Saribudolok. After having analyzed the collected data, the research finding showed that there were 62 words out of 106 the taboo words of ten categories: sexual organ, sexual activity, cursing, swearing, calling people, action, disease, dwelling ghost and name of God which were  used stably across time (from 1930 to 2021) in Simalungun are 62 words, out of 106 words.

This study examined and compared the new innovative trend analysis (ITA) of monthly, seasonal and annual rainfall with traditional trend analysis methods in relation to soybean productivity in western Maharashtra. Spearman’s rank correlation, Mann-Kendall and its 6 different modifications were used to analyze the trends of rainfall, whereas Spearman’s rho, simple linear regression and Sen’s slope with two different modifications were employed to quantify the magnitude of trends at 1%, 5% and 10% level of significance. Autocorrelation coefficient was calculated at lag-1 and tested at 5% level of significance. Rainfall variability of the region is very high (CV>30) in all the months and seasons with positively skewed rainfall distribution. Our results revealed that out of 34-time series data analyzed, ITA was able to ide ntify all the significant trends (11 -time series) that can be detected by traditional methods. Meanwhile, ITA also identified trends in 17-time series which cannot be detected by any of the traditional methods. The study revealed significant increase in monsoon and annual rainfall values, which is helpful in sustaining soybean productivity in the western parts of the Maharashtra.

The values ??of Islamic teachings brought by the great prophet Muhammad SAW, according to him, if we further explore and learn about them in Islam they will be implemented in life and nationality, and can also help face all the problems faced by the Indonesian people . In essence, the main idea of ??Islamic socialism according to the understanding of HOS Tjokrominoto is how to position and function religion (in this case Islam) as a revolutionary force to liberate oppressed people both culturally and politically and politically. HOS Tjokroaminoto is the son of a priyai who started the struggle against colonialism through the Sarekat organization Islam which is based on Islamic ideology and Socialism. HOS Tjokroaminoto's Islamic education perspective is very significant in a country. Education in question is education based on Islamic teachings, because in that teaching humans can find national values.
Designing Standards-Setting for Levels of Mathematical Proficiency in Measurement and Geometry: Multidimensional Item Response Model
Authors: Phaniew Sudarat , Junpeng Putcharee , Tang Keow Ngang
Published: October 2021

This study intends to design and verify the quality of a model that measures mathematical proficiency and aims to set the standards in measuring levels of proficiency in the subjects of measurement and geometry. Construct modeling was employed to design a mathematical proficiency measurement model which consists of the mathematical process and the dimensions of a conceptual structure. A total of 517 Secondary Year 1 students were selected from the big data to participate as test-takers. Design-based research encompassing four phases was used to verify the quality of the mathematical proficiency measurement model. A Multidimensional Random Coefficient Multinomial Logit model was used to examine the standards-setting of the mathematical proficiency measurement model. The results indicated that the two dimensions of mathematical proficiency can be further divided into five levels, from non-response/irrelevance to strategic/extended thinking and extended abstract structure for mathematical process and conceptual structural dimensions, respectively. The assessment tool covers 18 items with 15 multiple-choice items and three subjective items in measurement and geometry. Moreover, the results also demonstrated that the validity evidence associated with the internal structure of the multidimensional model is fit. Besides, reliability evidence, as well as item fit, is compliance with the quality of the mathematical proficiency measurement model as illustrated in analysis of the standard error of measurement and infit and outfit of the items. Finally, the researchers managed to set standards for the mathematical proficiency measurement model based on the assessment criterion results from the Wright Map. In conclusion, the standards-setting of the mathematical proficiency measurement model provides substantial information, particularly for measuring those students who are above the lowest level of mathematical proficiency because the error for estimating proficiency was low.
De toepassing van artikel 13b Opiumwet en de positie van de burgemeester
Authors: Tops Pieter , de Vries Jan-Piet
Published: October 2021

The application of Art. 13b Opium Act and the position of the mayor

In the reduction of undermining crime in the Netherlands, the role of local government has become more important over the past decade. One of the means used for this is Article 13b of the Opium Act (the Damocles Act). That has evolved from a way of closing down local dealer properties to a means of disrupting the criminal drug world. In this article we analyse the developments that the application of the article has gone through. We make an inventory of the actual use of the article in a region known as one of the hotbeds of subversive crime in the Netherlands, the region of West and Central Brabant. Finally, we will discuss the consequences that application of the article has for the position of the mayor. Does this lead to a mayorship in which this officer becomes more of a ‘sheriff’ and less of a mayor? We show that this is not the case.

Authors: Sameni Hamid Reza , Vafaei Abbas Ali , Zarbakhsh Sam , Talebian Afsaneh , Aldaghi Mohammad Reza
Published: October 2021

Background: Memory loss is the main disorder accompanied by Alzheimer's disease (AD). Objectives: We aimed to investigate the protective effects of aminoguanidine (Amg) on cell apoptosis in the hippocampal CA1 region and memory impairment in male rats received scopolamine (Scop). Methods: Thirty male Wistar rats (200 - 250 g) were randomly divided into the three groups of saline-saline group, Scop + saline, and Scop + Amg groups. The rats received intraperitoneal injection of Scop (3 mg/kg) for seven days, and subsequently, 100 mg/kg of Amg or normal saline were intraperitoneally administrated for 14 consecutive days. The Morris water maze test was used to study memory deficits. Finally, the animals were anesthetized, hippocampi were quickly removed, histological study was performed, and hippocampal cell apoptosis was evaluated by the cresyl violet staining and the terminal deoxynucleotidyl transferase dUTP nick end labeling test, respectively. Results: Scop injection resulted in reduced pyramidal cells and increased cell apoptosis in the hippocampal CA1 area, and impaired spatial learning and memory. The administration of Amg significantly improved memory and improved the density of pyramidal cells in the hippocampal CA1 area of the rats (P < 0.01). Also, the number of apoptotic cells in the CA1 region of the hippocampus in the Scop + Amg group decreased compared to the Scop + saline group (P < 0.05). Conclusions: These data demonstrate that the intraperitoneal injection of Amg declined the number of apoptotic cells in the CA1 area of the hippocampus and improved memory impairment in the Scop-induced rat model of AD. It is suggested that Amg may have protective effects against AD.
La gentrification au Québec : les gens, les lieux, les pratiques
Authors: Maltais Alexandre , Bélanger Hélène
Published: October 2021

Le phénomène tour à tour qualifié de gentrification ou d’embourgeoisement, par lequel l’habitat populaire est investi par de nouvelles populations mieux nanties en capital culturel ou économique, s’est imposé au coeur des luttes urbaines et de l’action communautaire comme l’un des principaux enjeux contemporains de justice sociale. Dans ce texte, nous proposons d’abord quelques fragments d’une généalogie québécoise du concept de gentrification (ou d’embourgeoisement) et du phénomène qu’il recouvre, à partir d’éléments qui ne visent pas à clore mais bien à alimenter le débat scientifique sur des bases théoriques explicites et transparentes. Peut-on parler d’une ou de gentrifications québécoises et, si oui, quels sont les éléments constitutifs de cette singularité? Cette question est l’occasion d’esquisser un bilan de plusieurs décennies de débats et de recherches, en faisant ressortir certaines particularités du contexte québécois, et en identifiant un certain nombre d’angles morts, autour de trois axes : les gens; les lieux; les pratiques.
Vieillir et se loger. Précarité résidentielle et gentrification dans les quartiers centraux montréalais
Authors: Simard Julien
Published: October 2021

Les politiques publiques concernant le vieillissement ont toutes pour objectif le maintien à domicile du plus grand nombre de personnes vieillissantes. Comment vieillir chez-soi, dans un quartier central montréalais, si l’on est victime d’éviction ou de reprise de logement? Cet article explore les dynamiques et réalités entourant la précarité résidentielle chez des locataires âgés à faible revenu, participant de près ou de loin aux activités d’un comité de logement et résidant dans l’un de quatre quartiers centraux montréalais en gentrification (Villeray, La Petite-Patrie, Rosemont et le Plateau-Mont-Royal). À partir d’une étude de terrain réalisée dans le cadre d’une thèse en études urbaines menée à l’INRS-UCS, cette contribution démontre l’importance de prendre en compte la relation locative en tant que facteur influençant la précarité résidentielle et, conséquemment, la capacité au maintien dans les lieux des personnes vieillissantes.

Frédéric Lacroix, Pourquoi la loi 101 est un échec, Montréal, Boréal, 2020, 264 p.
Authors: Corbeil Jean-Pierre
Published: October 2021

Cette revue critique de l’ouvrage Pourquoi la loi 101 est un échec de Frédéric Lacroix remet en question l’approche ethnicisante et idéologiquement réductrice qu’utilise l’auteur pour analyser les dynamiques linguistiques au Québec. Elle exhorte à mieux réfléchir aux enjeux de la situation actuelle et future de la langue française au Québec en les décrivant dans toute leur complexité et en tenant compte de leurs multiples facettes. Cette revue expose non seulement la fragilité des postulats épistémologiques, méthodologiques et conceptuels sur lesquels s’appuie l’auteur de l’ouvrage pour étayer sa démonstration du caractère catastrophique de la situation actuelle du français au Québec, mais remet également en question le cadre théorique de l’ouvrage, reposant sur le concept de surcomplétude institutionnelle. La note critique propose un regard alternatif qui met en lumière quelques-unes des dimensions et perspectives théoriques et méthodologiques dont ne tient pas compte l’auteur et qui sont pourtant fondamentales si l’on veut faire un examen plus complet des dynamiques et des pratiques qui contribuent à l’évolution de la situation linguistique au Québec.
Medio siglo de visual merchandising en el retail textil: la inversión para crecer en el mercado que viene
Authors: Llovet Rodríguez Carmen
Published: October 2021

Alcance de la revisión: Esta investigación realiza una revisión del rol del visual merchandising en el retail textil para su aplicación en el entorno actual, definido por el sector como la primera gran transformación del retail por los cambios acelerados por la pandemia en toda la cadena de valor (de la fórmula dependiente-mostrador- cliente) en 200 años.

Período de las publicaciones revisadas: Se analizan las investigaciones que entre 1980 y 2020 subrayan el uso de la tienda como elemento de comunicación y marketing. El punto de partida es la década de los 80, cuando se dio la primera revolución destacada en la tienda: Benetton eliminó mostradores y cajas y dispuso las camisetas por colores sin necesidad de vendedor.

Origen y tipos de documentos revisados: Se revisan artículos de revistas indexadas y manuales especializados en las áreas de marketing, consumo, comunicación, distribución y diseño, presentes en bases de datos nacionales e internacionales y en la Biblioteca Nacional de España.

Aportación del autor a las publicaciones analizadas: El estudio identifica las funciones del visual merchandising para responder a la necesidad de los retailers de adaptarse a las altas expectativas de los consumidores, vinculadas a las innovaciones tecnológicas en el diseño y en el ambiente o a decisiones de compra basadas en estímulos externos, más rápidas y menos motivadas por un esfuerzo cognitivo.

Conclusiones sobre las líneas de investigación estudiadas: Las principales funciones del visual merchandising son: 1) representación del producto en la imaginación del consumidor, de tal forma que convierte la experiencia de compra en una aventura y un descubrimiento continuo; 2) representación del estilo o forma de ser de la marca; 3) mejora de la experiencia de compra 4) presentación de la identidad corporativa, único rasgo que se muestra visible a los públicos; y 5) control de lo que el cliente ve y experimenta en la tienda.
Transvenous injection of n-butyl 2-cyanoacrylate to obliterate the pathologic cavernous sinus as a salvage technique for incompletely obliterated complex cavernous sinus dural arteriovenous fistula after transvenous coil embolization
Authors: Jung Joo Young , Lee Jong Young
Published: October 2021

A Barrow type D of complex cavernous sinus dural arteriovenous fistula (CS-dAVF) was completely obliterated by using coils, n-butyl 2-cyanoacrylate (NBCA) and Onyx via transvenous approach. Especially in this case, after transvenous coil embolization of the pathologic cavernous sinus (CS), transvenous injection of NBCA was done to obliterate residual shunts recruited into CS. The complex CS-dAVF was completely obliterated without periprocedural complications. Transvenous injection of NBCA could be considered as a feasible option for obliteration of pathologic CS in a case of incompletely obliterated complex CS-dAVF after transvenous coil embolization.

Immediate Effect of Kinesiology Tape on Functionality, Static and Dynamic Balance, Exercise Capacity, and Posture in Users of High-Heeled Shoes
Authors: Huzmeli Irem , Sari Zubeyir , Hallaceli Hasan , Gokcek Ozden , Davut Serkan
Published: October 2021

Background: Using high-heeled shoes in daily life affects the stability of walking, body posture, and functionality. We aimed to determine the immediate effect of kinesiology taping (KT) on functionality, static and dynamic balance, exercise capacity, and posture in young women using high-heeled shoes.

Methods: Thirty-seven women who wore high-heeled shoes (mean ± SD age, 20.32 ± 1.37 years) were divided into control (n = 20) and study (n = 17) groups. Both limbs of study group participants were taped medially, laterally, and dorsally with KT; no application was made to the control group. Balance (TecnoBody postural line), functionality (vertical jump and functional reach tests), exercise capacity (6-Minute Walk Test), and human body posture (New York Posture Rating Chart) were assessed.

Results: Median use of high-heeled shoes was 8 hours daily, 5 days weekly, and 3 years in the study group versus 6 hours daily, 4 days weekly, and 4 years in the control group. Significance in functional reach distance was found within the control (P = .010) and study (P = .005) groups but not between the groups. Stabilometric monopedal right foot ellipse area (P = .016) and perimeter (P = .009); left foot ellipse area (P = .016), perimeter (P = .023), and front/back standard deviation (P = .018); and dynamic balance area gap percentage (P = .030) were significant within the study group. Posture, vertical jump distance, exercise capacity, stabilometric test results, and bipedal closed-eye and opened-eye results were similar within and between groups (P > .05).

Conclusions: Kinesiology taping has no immediate effect on exercise capacity, vertical jump function, posture, and bipedal static balance but can modulate functional reach function, static monopedal leg balance, and dynamic equilibrium. Further studies are recommended to investigate the additive effect of KT with high-heeled shoes and after 45 min, 24 hours, and 72 hours.
Plasticity of olfactory bulb inputs mediated by dendritic NMDA-spikes in rodent piriform cortex
Authors: Kumar Amit , Barkai Edi , Schiller Jackie
Published: October 2021

The piriform cortex (PCx) is essential for learning of odor information. The current view postulates that odor learning in the PCx is mainly due to plasticity in intracortical (IC) synapses, while odor information from the olfactory bulb carried via the lateral olfactory tract (LOT) is ‘hardwired.’ Here, we revisit this notion by studying location- and pathway-dependent plasticity rules. We find that in contrast to the prevailing view, synaptic and optogenetically activated LOT synapses undergo strong and robust long-term potentiation (LTP) mediated by only a few local NMDA-spikes delivered at theta frequency, while global spike timing-dependent plasticity (STDP) protocols failed to induce LTP in these distal synapses. In contrast, IC synapses in apical and basal dendrites undergo plasticity with both NMDA-spikes and STDP protocols but to a smaller extent compared with LOT synapses. These results are consistent with a self-potentiating mechanism of odor information via NMDA-spikes that can form branch-specific memory traces of odors that can further associate with contextual IC information via STDP mechanisms to provide cognitive and emotional value to odors.
The I’m Learning! intervention methodology for quality learning environments in developing country contexts
Authors: Ryall Cameron , Zook Lisa
Published: October 2021

Within the context of the global learning crisis and calls to focus on the quality of education, one international organisation took a systematic and holistic approach to improve learning, wellbeing, and development in schools. Known as the Quality Learning Environment (QLE) Framework, it conceptualised the quality of the learning environment in schools with four guiding principles: emotional and psychological protection of learners, physical wellbeing of children, active learning processes, and close collaboration between school and parents/community. From 2013 – 2017, the framework was piloted in three countries of Cambodia, Uganda, and Zimbabwe to improve learning environments and outcomes while documenting the process, methods, and results of the QLE pilot in their country. The interventions in the three countries were closely tracked by a longitudinal research study. This paper explores the ambition of global and national research firms to carry out rigorous cross-country research alongside contextualized and evolving school interventions.
Mind the gaps: On the North/South Nexus in the ‘Sport for Development and Peace’ discourse
Authors: Mwansa Kabanda , Kiuppis Florian
Published: October 2021

In this conceptual article, we present the “Sport for Development and Peace” (SDP) discourse as a case of scientific rationalization. First, we shed light on the ongoing theory debate around the “global/local problematique” in globalization and global policy research in comparative and international education. We then link up with the SDP discourse and show that academic work mostly features research related to the fact that the majority of the SDP programmes and ways of implementing them have been conceptualized in the Global North, yet are to be implemented in the Global South. In that context, we illustrate International Organizations as sites of scientized knowledge production and translation. Scientific rationalization occurs when specialized technical knowledge and management techniques enter the discourse.
Square Waveguide Polarizer with Diagonally Located Irises for Ka-Band Antenna Systems
Authors: Piltyay S.
Published: October 2021

This article presents the results of development and optimization of a new square waveguide polarizer with diagonally located square irises. The application of suggested geometrical modification of irises form and location instead of a standard wall-to-wall irises configuration allows to exclude 45-degree twists between wideband waveguide polarizer and orthomode transducer of a dual-polarized antenna feed system. In addition, a waveguide polarizer and polarization duplexer can be manufactured by milling technology as two single details, which makes the proposed engineering solution reliable, simple for simulation, development and application. Suggested new polarizer design was developed for the satellite operating Ka-band. It contains 12 irises, which are symmetrically located in the diagonal corners of a square waveguide. Obtained optimal polarization converter provides excellent matching and polarization performance. The maximum level of VSWR is less than 1.04 for both orthogonal polarizations. Values of cross-polarization discrimination are higher than 32 dB in the operating Ka-band. Developed square waveguide polarizer with diagonally located irises can be applied in modern wideband satellite antennas.

Authors: Alharbi Abdullah , Alyami Hashem , M Poongodi , Rauf Hafiz Tayyab , Kadry Seifedine
Published: October 2021

The proposed research motivates the 6G cellular networking for the Internet of Everything’s (IoE) usage empowerment that is currently not compatible with 5G. For 6G, more innovative technological resources are required to be handled by Mobile Edge Computing (MEC). Although the demand for change in service from different sectors, the increase in IoE, the limitation of available computing resources of MEC, and intelligent resource solutions are getting much more significant. This research used IScaler, an effective model for intelligent service placement solutions and resource scaling. IScaler is considered to be made for MEC in Deep Reinforcement Learning (DRL). The paper has considered several requirements for making service placement decisions. The research also highlights several challenges geared by architectonics that submerge an Intelligent Scaling and Placement module.

It has been shown that selective etching improves the bond strength of some self-adhesive resin cements to enamel. The same has yet to be determined with dentin pre-treatment.

Purpose

To evaluate the tensile bond strength of two self-adhesive resin cements after two dentin surface pre-treatments, and also to analyze the cement/dentin interface.

Material and Methods

One hundred and twelve human third molars were extracted. The teeth were distributed into seven groups (n = 16). Maxcem Elite Chroma (MAX) (Kerr, Scafati, Italy) and Relyx U200 (RLX) (3M ESPE, Neuss, Germany) were used without pre-treatment or with two dentin pre-treatments (polyacrylic acid or phosphoric acid). A conventional etch-and-rinse (EAR) luting cement, NX3 Nexus (NX3) (Kerr, Scafati, Italy), was used as an external control group. Before testing, all specimens were stored in distilled water for 24 hours. Three specimens from each group were prepared for scanning electron microscopy observation (SEM). A tensile bond strength test (TBS) was performed for the remaining samples. The data were statistically analyzed using the Kruskal–Wallis test and Pairwise comparisons using the Wilcoxon rank sum test.

Results

MAX without pre-treatment and with phosphoric acid etching attained statistically similar bond strengths to NX3 (P > 0.05). There was a statistical difference (P = 0.00488) between RLX without pre-treatment (5.62 MPa) and NX3 (10.88 MPa). Phosphoric acid pre-treatment increases the bond strength values of RLX to a strength that is comparable to NX3 (P > 0.05). The lowest tensile bond strength (TBS) was attained after the application of polyacrylic acid with MAX (1.98 MPa). No statistical differences were found between the RLX bond strength values after polyacrylic acid treatment and RLX without pre-treatment or NX3 (P > 0.05). SEM observations disclosed an enhanced potential of the self-adhesive cements to infiltrate into dentin tubules and form resin tags when applied after phosphoric acid pre-treatment. The failure mode was dominantly adhesive.

Conclusions

On dentin, the self-adhesive resin cement MAX might be an effective alternative to conventional resin cement. Etching the dentin with phosphoric acid does not have a negative effect on the bond strength of MAX to dentin. On the other hand, phosphoric acid improved the bond strength of RLX when compared to EAR cement.
Functional drug–target–disease network analysis of gene–phenotype connectivity for curcumin in hepatocellular carcinoma
Authors: Zhao Yuanyuan , Tao Jiahao , Chen Zhuangzhong , Li Suihui , Liu Zeyu , Lin Lizhu , Zhai Linzhu
Published: October 2021

Background

The anti-tumor properties of curcumin have been demonstrated for many types of cancer. However, a systematic functional and biological analysis of its target proteins has yet to be fully documented. The aim of this study was to explore the underlying mechanisms of curcumin and broaden the perspective of targeted therapies.

Methods

Direct protein targets (DPTs) of curcumin were searched in the DrugBank database. Using the STRING database, the interactions between curcumin and DPTs and indirect protein targets (IPTs) weres documented. The protein–protein interaction (PPI) network of curcumin-mediated proteins was visualized using Cytoscape. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis was performed for all curcumin-mediated proteins. Furthermore, the cancer targets were searched in the Comparative Toxicogenomics Database (CTD). The overlapping targets were studied using Kaplan–Meier analysis to evaluate cancer survival. Further genomic analysis of overlapping genes was conducted using the cBioPortal database. Lastly, MTT, quantitative polymerase chain reaction (qPCR), and western blot (WB) analysis were used to validate the predicted results on hepatocellular carcinoma (HCC) cells.

Results

A total of five DPTs and 199 IPTs were found. These protein targets were found in 121 molecular pathways analyzed via KEGG enrichment. Based on the anti-tumor properties of curcumin, two pathways were selected, including pathways in cancer (36 genes) and HCC (22 genes). Overlapping with 505 HCC-related gene sets identified in CTD, five genes (TP53, RB1, TGFB1, GSTP1, and GSTM1) were finally identified. High mRNA levels of TP53, RB1, and GSTM1 indicated a prolonged overall survival (OS) in HCC, whereas elevated mRNA levels of TGFB1 were correlated with poor prognosis. The viability of both HepG2 cells and Hep3B cells was significantly reduced by curcumin at concentrations of 20 or 30 μM after 48 or 72 h of culture. At a concentration of 20 μM curcumin cultured for 48 h, the expression of TGFB1 and GSTP1 in Hep3B cells was reduced significantly in qPCR analysis, and reduced TGFB1 protein expression was also found in Hep3B cells.

Background

Renal ischemia-reperfusion injury (IRI) is a disease with high incidence rate in kidney related surgery. Micro RNA (miRNA) and transcription factors (TFs) are widely involved in the process of renal IRI through regulation of their target genes. However, the regulatory relationships and functional roles of TFs, miRNAs and mRNAs in the progression of renal IRI are insufficiently understood. The present study aimed to clarify the underlying mechanism of regulatory relationships in renal IRI.

Methods

Six gene expression profiles were downloaded from Gene Expression Omnibus (GEO). Differently expressed genes (DEGs) and differently expressed miRNAs (DEMs) were identified through RRA integrated analysis of mRNA datasets (GSE39548, GSE87025, GSE52004, GSE71647, and GSE131288) and miRNA datasets (GSE29495). miRDB and TransmiR v2.0 database were applied to predict target genes of miRNA and TFs, respectively. DEGs were applied for Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, followed with construction of protein-protein interaction (PPI) network. Then, the TF-miRNA-mRNA network was constructed. Correlation coefficient and ROC analysis were used to verify regulatory relationship between genes and their diagnostic value in GSE52004. Furthermore, in independent mouse RNA-seq datasets GSE98622, human RNA-seq GSE134386 and in vitro, the expression of hub genes and genes from the network were observed and correlation coefficient and ROC analysis were validated.

Results

A total of 21 DEMs and 187 DEGs were identified in renal IRI group compared to control group. The results of PPI analysis showed 15 hub genes. The TF-miRNA-mRNA regulatory network was constructed and several important pathways were identified and further verified, including Junb-miR-223-Ranbp3l, Cebpb-miR-223-Ranbp3l, Cebpb-miR-21-Ranbp3l and Cebpb-miR-181b-Bsnd. Four regulatory loops were identified, including Fosl2-miR-155, Fosl2-miR-146a, Cebpb-miR-155 and Mafk-miR-25. The hub genes and genes in the network showed good diagnostic value in mice and human.

Conclusions

In this study, we found 15 hub genes and several TF-miRNA-mRNA pathways, which are helpful for understanding the molecular and regulatory mechanisms in renal IRI. Junb-miR-223-Ranbp3l, Cebpb-miR-223-Ranbp3l, Cebpb-miR-21-Ranbp3l and Cebpb-miR-181b-Bsnd were the most important pathways, while Spp1, Fos, Timp1, Tnc, Fosl2 and Junb were the most important hub genes. Fosl2-miR-155, Fosl2-miR-146a, Cebpb-miR-155 and Mafk-miR-25 might be the negative feedback loops in renal IRI.
