In vitro evaluation of the effectiveness of different organic solvents in Gutta-percha removal

Objective: The objective of this study was to evaluate the effectiveness of eucalyptus oil, orange oil and orange liquid in removing gutta-percha in the endodontic retreatment. Methods: Forty human mandibular incisors with single straight root canals were prepared with ProTaper Next (up to size x3) and filled by cold lateral condensation with gutta-percha and Ad Seal Filler (Prevest Dent Pro Limited, Digiana, India). After filling the roots were incubated for 1 month at 37oC and 100% humidity. The 40 teeth were divided into one control group and 3 retreatment groups (n = 10 each). Gutta-percha was removed using K-files and different solvents: orange oil, eucalyptus oil, orange liquid. After retreatment roots were longitudinally separated and examined by Carl Zeiss Stemi 2000cs stereomicroscope with Image Recording Camera AxioCam Mrc5. The resulting data was processed by Axio Vision 4.7 Image Analysis. Measure the area of the canals and the remaining gutta-percha areas along the entire canal. Analyzed using statistical package SPSS 20 at a statistically reliable level keeping p <0.05. Results: No statistically significant differences were found between orange oil, orange liquid and eucalyptus oil in softening gutta-percha (p> 0.05). However, the control group had the maximum amount remaining filling material (p<0.05). Conclusion: The use of solvent statistically significant reduces the amount of remaining filling material in the root canal. Orange oil is best solvent in the coronal and middle third. In the apical third the most effective solvent is eucalyptus oil.
Poverty Groups Identification and Assessment of Poverty Alleviation Programs in Rural China

This study analyzed the outcomes of 194 individuals living in rural poverty in Guizhou Province using data obtained from a poverty alleviation information system together with several machine-learning tools. First, four dimensions were abstracted from a multiple factor analysis: family background and work condition, self-development, regional context, and health status and labor capacity. Second, five heterogeneous groups were identified through k-medoids clustering based on the above dimensions. The results showed that the most significant differences among poverty groups were related to health status and household size. The effectiveness of poverty alleviation programs for the different poverty groups was then evaluated. By employing association rule mining, we showed that education assistance is effective in poverty groups in relatively ‘good’ condition but not in others, whereas the ‘Minimum Living Standard’ program failed in all groups, particularly when it was the sole program. Thus, our study indicated that additional targeted alleviation programs should be implemented to address the needs of different poverty groups, especially in terms of education assistance, medical care, and medical prevention programs.
Distribution of DTPA-extractable micronutrient cations (Zn, Fe, Mn, and Cu) and its relationship with physico-chemical properties in soils of Birbhum district, West Bengal

The present investigation was carried out for evaluation of the status of DTPAZn, Fe, Mn, and Cu in relation with physico-chemical properties in soils of Birbhum district, West Bengal. Total 90 surface soil samples were collected from three different blocks namely Md. Bazar, Nalhati and Bolpur. Collected soil samples were analyzed for pH, electrical conductivity, organic carbon, textural class, Available P and DTPAextractable micronutrients using standard analytical methods. In general, textural class ranged from sandy loam to sandy clay loam. Soils were strong to moderately acidic in reaction. Electrical conductivity was found in normal range. Soil organic carbon status ranged from 0.24 to 0.81% and was low in available P status. The status of available Zn was sufficient to high level while status of available Fe, Mn and Cu was high. The DTPA-extractable zinc content in the surface soils under study varied from 0.37 to 1.28 mg kg with an average value 0.856 mg kg. The available iron, manganese and copper contents in soils ranged from 36.8-45.1, 15.1-17.9 and 2.5-3.2 mg kg respectively. From the correlation study it was found that soil pH significantly and negatively correlated with available zinc (r= -0.233*), iron(r= -0.42**) and manganese(r= -0.324*) whereas nonsignificantly with available copper (r= -0.132) content. Soil organic carbon showed significant and positive correlation with all the micronutrients except copper content. Non-significant and negative correlation was found between electrical conductivity and available micronutrients. Clay content correlated significantly and negatively with available Mn (r= -0.172*) and positively with available Zn (r=0.535**). Significant and negative correlation showed between available P with available Zn and Fe.
Economic Development and Sustainable Human Resources by Supply Chain Managament in Government Towards in West Kalimantan Indonesia

Abstract- The growth of global supply chains has changed the distribution of incomes across countries. Participation in these supply chains, initiated by the successful completion of low value-added manufacturing tasks, contributed to industrialisation and high rates of economic growth in several Asian developing economies. The quality of economic development and sustainable human resources in government can be seen from excellent service for the realization of a mental revolution. These qualities are demonstrated through the attitude of government officials who are friendly, polite, and a work ethic that is disciplined, productive, and innovative. But the service in Sungai Ambawang Kuala Village, West Kalimantan Indonesia, was allegedly not yet excellent. For this reason, the purpose of this study is to analyze excellent service leading to a mental revolution in the apparatus of Sungai Ambawang Kuala Village through a descriptive qualitative method. Data was collected through observations on the quality of services carried out by the apparatus in Sungai Ambawang Kuala Village, interviews with village heads, village secretaries, heads of government affairs, hamlet heads, and community leaders, and by collecting documents related to services in Sungai Ambawang Kuala Village. Based on research, it is known that until the end of 2016 the village profile as a village development planning document has not been realized and does not yet have clear service standards. It was found that the quality of service of the apparatus of Sungai Ambawang Kuala Village was fulfilled in the aspect of guarantee, real, empathy, and responsiveness but it was still lacking in the aspect of reliability. The conclusion of this study, to overcome the lack of service of government apparatus in serving the community, the concept of service apparatus is harmonized with the vision of a mental revolution that emphasizes the work ethic and the spirit of mutual cooperation. The recommendation given is the existence of a synergistic social movement between the government and the community in routine activities starting from the scope of the family, school to the community.
Angiogenic gene therapy for improving islet graft vascularization

Clinical islet transplantation is considered a curative treatment for type 1 diabetes, but long-term survival and function of implanted islets is greatly compromised by a number of adverse events. In addition to immune rejection and recurrent autoimmunity, the survival and function of islets is determined by the rate and degree of islet revascularization, an essential process termed angiogenesis that is required for the development of new vessels within islet grafts to derive blood from the host vasculature. Rapid and adequate revascularization is crucial for islet survival and function. Delay in islet revascularization can deprive islets of oxygen and nutrients, resulting in islet cell death and early graft failure. There is evidence that despite the infusion of sufficiently large amounts of islets (~11,000 islets/kg body weight) per diabetic recipient, less than 30% of islet mass becomes stably engrafted post transplantation. In this article, we will review the molecular basis of islet revascularization and highlight the importance of developing novel therapeutic strategies to stimulate angiogenesis within islet grafts and enhance islet graft vascularization post transplantation. Such strategies, when applied in conjunction with islet transplantation, are expected to improve the viability of transplanted islets and provide long-term survival of functional islet mass post transplantation, thereby increasing the overall success rate of islet transplantation.

The relationship between the quality of school life and the school burnout

School burnout has been a research subject during recent years and is a wide case among students is associated with many factors. Among these factors, school-related concepts are remarkable. Within this study, it is aimed to investigate the relationship between school quality, school burnout and school burnout. The participant group of the study consists of a total of 364 secondary school students, 181 girls and 183 boys, whose ages are in the range of 10-15, attending various secondary schools. This sampling was determined by the maximum diversity sampling method. The data were collected with the school quality of life and school burnout scale. In the analysis of the data, correlation and structural equation model analysis were administrated. It was concluded that there is a negative relationship between school quality of life and school burnout, and that school quality of life is a negative predictor of school burnout. The results were discussed through the literature review and suggestions were made for researchers and practitioners.
Institutional Repository Simplified modelling of vehicle interior noise : comparison of analytical , numerical and experimental approaches

The present paper describes the results of the investigation of low and medium frequency vehicle interior noise carried out using simplified structural-acoustic models. Analytical, finite element (FE) and experimental studies are presented and compared. In particular, the analytical approach is based on the formula representing the interior acoustic pressure in terms of structural and acoustic normal modes. This procedure does not take into account the effect of the enclosed air on structural vibrations. The FE analysis considers structural vibration modes, interior acoustic modes, full structural-acoustic interaction and the resulting structure-borne noise. The above-mentioned analytical and numerical results are compared with each other, and both of them are compared with the experimental results obtained for the simplified reduced-scale vehicle model “QUASICAR” developed in Loughborough University. The comparisons demonstrate some specific features of the analytical and numerical approaches and outline the acceptable limits of simplification in modelling vehicle interior noise. Although this study is concerned with structure-borne vehicle interior noise, its results and conclusions could be of interest for a wider range of engineering problems, such as building acoustics and dynamics of thin shell structures.
Agrowaste-based Polyhydroxyalkanoate (PHA) production using hydrolytic potential of Bacillus thuringiensis IAM 12077

The study identified the innate enzymatic potential (amylase) of the PHB producing strain B.thuringiensis IAM 12077 and explored the same for cost-effective production of PHB using agrowastes, eliminating the need for pretreatment (acid hydrolysis and/or commercial enzyme). Comparative polyhydroxyalkanoate (PHA) production by B. thuringiensis IAM 12077 in biphasic growth conditions using glucose and starch showed appreciable levels of growth (5.7 and 6.8 g/L) and PHA production (58.5 and 41.5%) with a PHA yield of 3.3 and 2.8 g/L, respectively. Nitrogen deficiency supported maximum PHA yield (2.46 g/L) and accumulation (53.3%). Maximum growth (3.6 g/L), PHB yield (2.6 g/L) and PHA accumulation (72.8%) was obtained with C:N ratio of 8:1 using starch as the carbon source (10 g/L). Nine substrates (agro and food wastes) viz. rice husk, wheat bran, ragi husk, jowar husk, jackfruit seed powder, mango peel, potato peel, bagasse and straw were subjected to two treatments- acid hydrolysis and hydrolysis by innate enzymes, and the reducing sugars released thereby were utilized for polymer production. All the substrates tested supported comparable PHB production with acid hydrolysis (0.96 g/L-8.03 g/L) and enzyme hydrolysis (0.96 g/L -5.16 g/L). Mango peel yielded the highest PHB (4.03 g/L; 51.3%), followed by jackfruit seed powder (3.93 g/L; 29.32%). Varied levels of amylase activity (0.25U-10U) in all the substrates suggested the enzymatic hydrolysis of agrowastes.
The influence of an interlayer on coating delamination under contact loading

The objective of this work is to study indentation induced delamination of a strong film from a two layer system. To this end our model is composed of an elastic diamond coating, and a chrome interlayer and a tungsten carbide substrate, both elastic plastic. The interface between the coating and the interlayer is supposed weaker than between the interlayer and the substrate, thus the first one is modelled with a cohesive zone and a Xu-Needleman constitutive law while the second one is rigid. In addition only normal delamination is studied here, for in these conditions it always appears for a smaller indentation force than for shear delamination. Delamination initiation is studied for several properties of the system through the evolution of the critical force with the interlayer thickness. Depending of the cohesive zone and the interlayer material properties, it is found that the critical force achieve a maximum with an interlayer thickness of a half to two times the coating thickness. The value of this maximum goes from two to five times the critical force for delamination of a two layer system. It is also demonstrated that this maximum tends to appear for smaller thickness if the cohesive zone is weaker, which could be very interesting for industrial applications.
When Scenes Look Like Materials: René Magritte’s Reversible Figure–Ground Motif

We draw attention to a frequent motif in the work of the Belgian surrealist René Magritte (1898–1967). In the motif, a scene is depicted that contains a silhouette, which itself contains another depicted scene. The silhouette is bistable, appearing either as a figural region whose positive space is covered, or filled, with the interior scene texture, or as a ground region providing a window onto a more distant scene. We call this the ‘reversible figure–ground motif’. Because the stimulus does not change when our percept changes, the motif’s appearance at any particular moment cannot be explained by its local or global image statistics. Instead principles of perceptual organization, and in particular image segmentation and figure–ground assignment, appear crucial for determining whether the interior of the silhouette is processed as a material vs. a scene — which in turn reflects the fundamental role of visual segmentation in material and scene perception more generally.
Title LKB 1 tumor suppressor and salt-inducible kinases negativelyregulate human T-cell leukemia virus type 1 transcription

Background: Human T-cell leukemia virus type 1 (HTLV-1) causes adult T-cell leukemia (ATL). Treatment options are limited and prophylactic agents are not available. We have previously demonstrated an essential role for CREB-regulating transcriptional coactivators (CRTCs) in HTLV-1 transcription. Results: In this study we report on the negative regulatory role of LKB1 tumor suppressor and salt-inducible kinases (SIKs) in the activation of HTLV-1 long terminal repeats (LTR) by the oncoprotein Tax. Activation of LKB1 and SIKs effectively blunted Tax activity in a phosphorylation-dependent manner, whereas compromising these kinases, but not AMP-dependent protein kinases, augmented Tax function. Activated LKB1 and SIKs associated with Tax and suppressed Tax-induced LTR activation by counteracting CRTCs and CREB. Enforced expression of LKB1 or SIK1 in cells transfected with HTLV-1 molecular clone pX1MT repressed proviral transcription. On the contrary, depletion of LKB1 in pX1MT-transfected cells and in HTLV-1-transformed T cells boosted the expression of Tax. Treatment of HTLV-1 transformed cells with metformin led to LKB1/SIK1 activation, reduction in Tax expression, and inhibition of cell proliferation. Conclusions: Our findings revealed a new function of LKB1 and SIKs as negative regulators of HTLV-1 transcription. Pharmaceutical activation of LKB1 and SIKs might be considered as a new strategy in anti-HTLV-1 and anti-ATL therapy.
One More Resource Curse: Dutch Disease and Export Concentration

Economists have long discussed the negative effect of Dutch disease episodes on the non-resource tradable sector as a whole, but little has been said on its impact on the composition of the non-resource export sector. This paper fills this gap by exploring to what extent concentration of a country's non-resource export basket is determined by their exports of natural resources. We present a theoretical framework that shows how upward pressure in wages caused by a resource windfall results in higher export concentration. We then document two robust empirical findings consistent with the theory. First, using data on discovery of oil and gas fields and of commodity prices as sources of exogenous variation, we find that countries with larger shares of natural resources in exports have more concentrated non-resource export baskets. Second, we find capital-intensive exports tend to dominate the export basket of countries prone to Dutch disease episodes.
Biochemical and Molecular Roles of Nutrients Dietary Isoflavones Reduce Plasma Cholesterol and Atherosclerosis in C 57 BL / 6 Mice but not LDL Receptor – Deficient Mice 1 , 2

Susceptibility to atherosclerosis is determined by a combination of genetic and environmental factors, including diet. Consumption of diets rich in soy protein has been claimed to protect against the development of atherosclerosis. Potential mechanisms include cholesterol lowering, inhibition of lipoprotein oxidation and inhibition of cell proliferation by soy proteins or isoflavones, such as genistein, that are present in soy. This study was designed to determine whether soy isoflavones confer protection against atherosclerosis in mice and whether they reduce serum cholesterol levels and lipoprotein oxidation. C57BL/6 and LDL receptor–deficient (LDLr-null) mice were fed soy protein–based, high fat diets with isoflavones present (IF/, 20.85 g/100 g protein, 0.027 g/ 100 g genistein, 0.009 g/100 g daidzein) or diets from which isoflavones, and possibly other components, had been extracted (IF0, 20.0 g/100 g protein, 0.002 g/100 g genistein, 0.001 g/100 g daidzein). Because LDLr-null mice develop extensive atherosclerosis and hypercholesterolemia after minimal time on a high fat diet, they were fed the diets for 6 wk, whereas C57BL/6 mice were fed the diets for 10 wk. Plasma cholesterol levels did not differ between LDLr-null mice fed IF0 and those fed IF/, but were 30% lower in C57BL/6 mice fed the IF/ diet than in those fed the IF0 diet. Susceptibility of LDL to oxidative modification, measured as the lag phase of conjugated diene formation in LDLr-null mice, was not altered by isoflavone consumption. All LDLr-null mice developed atherosclerosis, and the presence or deficiency of dietary isoflavones did not influence atherosclerotic lesion area. In contrast, atherosclerotic lesion area was significantly reduced in C57BL/6 mice fed IF/ compared with those fed IF0. Thus, this study demonstrates that although the isoflavone-containing diet resulted in a reduction in cholesterol levels in C57BL/6 mice, it had no effect on cholesterol levels or on susceptibility of LDL to oxidative modification in LDLr-null mice. Further, dietary isoflavones did not protect against the development of atherosclerosis in LDLr-null mice but did decrease atherosclerosis in C57BL/6 mice. These findings suggest that soy isoflavones might lower cholesterol levels by increasing LDL receptor activity, and the reduction in cholesterol may offer some protection against atherosclerosis. J.
