Metallothionein overexpression and its prognostic relevance in intrahepatic cholangiocarcinoma and extrahepatic hilar cholangiocarcinoma (Klatskin tu…
2009
Metallothionein is a group of small molecular weight cysteine-rich proteins with a broad variety of functions. Metallothionein has been shown to regulate apoptosis and proliferation. Overexpression of metallothionein frequently occurs in human tumors and is related to prognosis as well as therapy response. However, metallothionein expression and its clinical relevance in cholangiocarcinoma have not been investigated. The present study aimed to analyze metallothionein over-expression and its possible prognostic impact in intrahepatic cholangiocarcinoma and hilar extrahepatic cholangiocarcinoma (Klatskin tumors). We investigated the relationship of immunohistochemically demonstrated metalloth…
Synovial giant cells in rheumatoid arthritis: Expression of cystatin C, but not of cathepsin B
2000
This study was designed to investigate the expression of the matrix degrading proteinase cathepsin B and its endogenous inhibitor cystatin C in rheumatoid arthritis (RA) with special regard to multinucleated synovial giant cells (SGC). We applied an immunohistochemical double-labeling technique. SGC strongly expressed cystatin C and CD68, but were negative for cathepsin B. This staining pattern occurred in osteoclasts as well. Our findings support the idea that in RA matrix destruction by cathepsin B is not mediated by SGC or osteoclasts, but by mononuclear synoviocytes.

A discourse on human hair fibers and reflections on the conservation of drug molecules
1996
A gross discourse on human hair fibers and their formation is presented stressing the various interdisciplinary aspects, such as the morphological, biological, structural and biochemical data considered to be important in the field of hair analysis. An attempt is made to explain the incorporation of drug molecules during hair fiber formation by using the classical concepts of drug absorption based on lipoid theory and the pH-partition hypothesis as well as a modern biological approach on the permeability of cell membranes. In addition to the physiochemical considerations of the transport properties of a particular drug molecule such as a) the lipophilicity, which determines permeability thr…
Validation of a set of reference genes to study response to herbicide stress in grasses
2012
Abstract Background Non-target-site based resistance to herbicides is a major threat to the chemical control of agronomically noxious weeds. This adaptive trait is endowed by differences in the expression of a number of genes in plants that are resistant or sensitive to herbicides. Quantification of the expression of such genes requires normalising qPCR data using reference genes with stable expression in the system studied as internal standards. The aim of this study was to validate reference genes in Alopecurus myosuroides, a grass (Poaceae) weed of economic and agronomic importance with no genomic resources. Results The stability of 11 candidate reference genes was assessed in plants res…
Variation in the TonB-dependent outer-membrane proteins in plant-associated strains of Pseudomonas fluorescens
2011
International audience; Genomic sequences of ten strains of plant-associated Pseudomonas spp. were surveyed for the presence of TonB-dependent outer-membrane proteins (TBDPs), which function in the uptake of substrates from the environment by many Gram-negative bacteria. The ten strains represent P. fluorescens, P. chlororaphis, and P. synxantha isolated from the phyllosphere, rhizosphere or soil. 14 to 45 TBDPs were identified in each strain, and phylogenetic analysis of the TBDPs identified five that are conserved across all ten genomes. Comparisons to proteins with known functions allowed the assignment of putative roles in uptake of heme, vitamin B12, copper, and the siderophore ferrich…

Life satisfaction and status among adolescent law offenders
2015
Background Life satisfaction among young offenders may be affected by the subjective experience of their social status and by the feeling of being a ‘loser’ compared with others, but it is not clear what variables affect such experiences in this group. Aims To examine relationships of type of sentence (prison or probation) and of gender with subjective social status, sense of defeat and life satisfaction among young offenders. Methods One hundred and five participants were randomly selected from a cohort of young offenders, stratifying for sentence type and for gender. They were interviewed by trained and experienced interviewers. Results Young people in a correctional facility experienced …
Decision-making Styles in Adolescent Offenders and Non-offenders: Effects of Emotional Intelligence and Empathy
2021
The literature indicates that adolescents with delinquent behavior have greater difficulty making rational decisions and show lower emotional intelligence and empathy. Decision-making is a set of complex processes associated with neurobiological, cognitive, emotional, and social factors which help regulate and guide behavior, which could be influenced by emotional intelligence and empathy. A comparative, correlational, and predictive study was conducted to analyze relationships and influence of emotional intelligence and empathy in decision-making styles in adolescent offenders and non-offenders. 808 Colombian adolescents between 14 and 18 years of age participated (50p offenders). The resu…
Male Police Officers’ Law Enforcement Preferences In Cases of Intimate Partner Violence Versus Non-Intimate Interpersonal Violence
2014
This article explores male police officers’ law enforcement preferences across different scenarios of interpersonal violence, involving intimate (partner violence against women) and non-intimate relationships (between- and within-gender). The influence of police officers’ sexist attitudes and empathy on their law enforcement preferences was also analyzed within and across these scenarios. The sample consisted of 308 male police officers. Results showed that police officers prefer a stronger and unconditional law enforcement approach in cases of violence against women, both in intimate and non-intimate relationships. Benevolent sexism was linked to a preference for a more conditional law en…
