Oxidative/Nitrative Stress and Inflammation Drive Progression of Doxorubicin-Induced Renal Fibrosis in Rats as Revealed by Comparing a Normal and a Fibrosis-Resistant Rat Strain

Chronic renal fibrosis is the final common pathway of end stage renal disease caused by glomerular or tubular pathologies. Genetic background has a strong influence on the progression of chronic renal fibrosis. We recently found that Rowett black hooded rats were resistant to renal fibrosis. We aimed to investigate the role of sustained inflammation and oxidative/nitrative stress in renal fibrosis progression using this new model. Our previous data suggested the involvement of podocytes, thus we investigated renal fibrosis initiated by doxorubicin-induced (5 mg/kg) podocyte damage. Doxorubicin induced progressive glomerular sclerosis followed by increasing proteinuria and reduced bodyweight gain in fibrosis-sensitive, Charles Dawley rats during an 8-week long observation period. In comparison, the fibrosis-resistant, Rowett black hooded rats had longer survival, milder proteinuria and reduced tubular damage as assessed by neutrophil gelatinase-associated lipocalin (NGAL) excretion, reduced loss of the slit diaphragm protein, nephrin, less glomerulosclerosis, tubulointerstitial fibrosis and matrix deposition assessed by periodic acid-Schiff, Picro-Sirius-red staining and fibronectin immunostaining. Less fibrosis was associated with reduced profibrotic transforming growth factor-beta, (TGF-beta1) connective tissue growth factor (CTGF), and collagen type I alpha 1 (COL-1a1) mRNA levels. Milder inflammation demonstrated by histology was confirmed by less monocyte chemotactic protein 1 (MCP-1) mRNA. As a consequence of less inflammation, less oxidative and nitrative stress was obvious by less neutrophil cytosolic factor 1 (p47phox) and NADPH oxidase-2 (p91phox) mRNA. Reduced oxidative enzyme expression was accompanied by less lipid peroxidation as demonstrated by 4-hydroxynonenal (HNE) and less protein nitrosylation demonstrated by nitrotyrosine (NT) immunohistochemistry and quantified by Western blot. Our results demonstrate that mediators of fibrosis, inflammation and oxidative/nitrative stress were suppressed in doxorubicin nephropathy in fibrosis-resistant Rowett black hooded rats underlying the importance of these pathomechanisms in the progression of renal fibrosis initiated by glomerular podocyte damage

Narcissism and the strategic pursuit of short-term mating : universal links across 11 world regions of the International Sexuality Description Project-2.

Previous studies have documented links between sub-clinical narcissism and the active pursuit of short-term mating strategies (e.g., unrestricted sociosexuality, marital infidelity, mate poaching). Nearly all of these investigations have relied solely on samples from Western cultures. In the current study, responses from a cross-cultural survey of 30,470 people across 53 nations spanning 11 world regions (North America, Central/South America, Northern Europe, Western Europe, Eastern Europe, Southern Europe, Middle East, Africa, Oceania, Southeast Asia, and East Asia) were used to evaluate whether narcissism (as measured by the Narcissistic Personality Inventory; NPI) was universally associated with short-term mating. Results revealed narcissism scores (including two broad factors and seven traditional facets as measured by the NPI) were functionally equivalent across cultures, reliably associating with key sexual outcomes (e.g., more active pursuit of short-term mating, intimate partner violence, and sexual aggression) and sex-related personality traits (e.g., higher extraversion and openness to experience). Whereas some features of personality (e.g., subjective well-being) were universally associated with socially adaptive facets of Narcissism (e.g., self-sufficiency), most indicators of short-term mating (e.g., unrestricted sociosexuality and marital infidelity) were universally associated with the socially maladaptive facets of narcissism (e.g., exploitativeness). Discussion addresses limitations of these cross-culturally universal findings and presents suggestions for future research into revealing the precise psychological features of narcissism that facilitate the strategic pursuit of short-term mating

En este estudio se han usado respuestas de la encuesta transcultural de 30.470 personas de 53 naciones de 11 regiones mundiales (América del Norte, América del Sur/América Central, Europa del Norte, Europa del Oeste, Europa del Este, Europa del Sur, Oriente Próximo, África, Asia del Sur/Sudoeste de Asia, Asia del Este y Oceanía) para evaluar si el narcisismo (medido por el Inventario de Personalidad Narcisista; NPI) se asocia panuniversalmente con los indicadores del emparejamiento a corto plazo, tanto en la dirección, como en la intensidad. Los resultados sugieren que el narcisismo (incluidos muchos aspectos suyos medidos por el NPI) tiene las mismas asociaciones básicas con los rasgos de personalidad relacionados con el sexo (p. ej. extraversión alta) y con los resultados sexuales claves (p. ej. búsqueda más activa de las estrategias del emparejamiento a corto plazo) a través de las 11 mayores regiones mundiales del PDSI 2. La discusión se enfoca en las implicaciones y limitaciones del estudio actual

Constraint Satisfaction Problems with Order-Sorted Domains

In order to improve constraint satisfaction techniques, a promising way is to use special features of constraints and variable domains. This paper examines a special class of CSPs (Constraint Satisfaction Problems) in which a partial order is defined on each domain and the constraints are compatible with these orders. A special arc-consistency algorithm for this case is presented and some questions about finding all solutions are discussed. The presented ideas can be used in constrait systems implemented in an object-oriented language, where inheritance hierarchy of objects is a natural support for the presented CSP type. 1 Introduction Many problems in Artificial Intelligence and Operational Research can be viewed as Constraint Satisfaction Problems (CSP). A classical CSP involves a set of variables each with an associated domain and a set of constraints. In the binary case, a constraint between two variables is a subset of the Cartesian product of their domains, specifying which val..

Yet Another Object-Oriented Constraint Resolution System: An Open Architecture Approach

In this paper we present YAFCRS, a new object-oriented constraint system which ensures backtracking-based global resolution. First, based on objects, we define a modular representation of constraint satisfaction problems and provide a general algorithmic framework to resolve them. Then, by the definition of compound constraint classes, we allow to state compound constraints on any objects. In order to demonstrate the possibilities of our system, we modelize, define, and resolve a small, typical scheduling problem

Creating Hybrid Solutions for Inventory Management Problems (Extended Abstract)

This paper presents an ongoing research in developing hybrid algorithms suitable for complex optimisation problems in CHIC-2 project (Esprit Project 22165). We present the modelling and solving of the Bouygues' application by two project partners: IC-Parc and Bouygues. The Bouygues' application is an inventory management problem which consists of two subproblems: a resource allocation subproblem and a maintenance scheduling subproblem. We demonstrate hybrid approaches which improve significantly the current results with respect to cost, quality, and integration. 1 The Bouygues' Application The CHIC-2 project tackles several applications, each supplied by a major end user in the project. The applications are of strategic business importance, illustrate the blending of combinatorial optimisation and domaindependent constraints. The aim of the project is to develop hybrid algo1 rithms suitable for industrial optimisation problems, to provide a methodology to support efficient exploitatio..

"I must be perfect": The role of irrational beliefs and perfectionism on the competitive anxiety of Hungarian athletes

In this study the influence of irrational beliefs and perfectionism on the emergence of competitive anxiety was investigated. While previous studies indicate that higher irrational beliefs predict greater competitive anxiety, in the present study it is hypothesised that this relationship is mediated by perfectionism. A serial atemporal multiple mediation analysis revealed that both adaptive and maladaptive perfectionism were significant partial mediators between irrational beliefs and competitive anxiety. The total score and all four subscale scores on irrational beliefs had both direct and indirect effects on cognitive competitive anxiety, the latter effects mediated by both forms of perfectionism. Depreciation beliefs had a direct effect, and demandingness and awfulizing had indirect effects, on somatic competitive anxiety when both forms of perfectionism were entered as mediators. These findings suggest that both irrational beliefs and perfectionism influence the emergence of competitive anxiety, therefore rational emotive behavioral therapy with a focus upon perfectionism may be an effective means of reducing competitive anxiety in athletes
