Acceptance of sexual attraction and its link to psychological distress and sexual offending among pedohebephilic clients: results from a preliminary analysis.

Introduction: Pedohebephilic disorder is characterized by intense sexual urges or fantasies involving children, which can lead to distress or sexual behavior with children. While theoretical and qualitative accounts suggest that accepting one's pedohebephilic sexual interests may help mitigate both distress and problematic behaviors, the only published quantitative study to date has linked acceptance with behavior but did not analyze its effect on distress.

Methods: We examined the relationship between acceptance of sexual interests and child sexual abuse (CSA), the use of child sexual exploitation material (CSEM), and psychological distress in 238 pedohebephilic and teleiophilic men outside the judicial system (i.

The Viewing Reaction Time as a Diagnostic Tool of Pedohebephilia in the Dunkelfeld.

Diagnosing pedohebephilia is fraught with obstacles given the tabooed nature of this sexual preference. The viewing reaction time effect (VRT) provides a non-intrusive indirect measure of sexual interest in minors. In forensic populations, the ability of the difference between the latencies while viewing child and adult sexual stimuli (VRT index) to discern child sexual offenders from a range of control groups has been ascertained meta-analytically.

Balancing selection in Pattern Recognition Receptor signalling pathways is associated with gene function and pleiotropy in a wild rodent.

Pathogen-mediated balancing selection is commonly considered to play an important role in the maintenance of genetic diversity, in particular in immune genes. However, the factors that may influence which immune genes are the targets of such selection are largely unknown. To address this, here we focus on Pattern Recognition Receptor (PRR) signalling pathways, which play a key role in innate immunity.

Misuse of Child Sexual Abuse Images: Treatment Course of a Self-Identified Pedophilic Pastor.

The recurrent use of child sexual abuse images (CSAI) for sexual arousal is considered a valid indicator for the existence of a pedophilic preference, which in turn represents a significant risk factor for committing contact offenses against children. Treatment programs for (potentially) sexually delinquent men endeavor to reduce the risk to offend by addressing relevant risk factors and emphasizing functional and socially acceptable alternative behaviors. Users of CSAI are a particular target group for prevention services and it has been suggested that the primary treatment focus should be on sexual self-regulation deficits.

Is Emotional Congruence With Children Associated With Sexual Offending in Pedophiles and Hebephiles From the Community?

Although emotional congruence with children (ECWC) is a risk factor for sexual offending against children, its conceptual validity has hardly been researched. This study aims to explore the construct of ECWC by evaluating the factor structure of the Child Identification Scale (CIS-R) and its relation to facets of sexual preference and child sexual abuse behaviors. It was hypothesized that the measure comprises consistent subscales that are differently associated with aspects of sexual preference and sexual offending against children.

Antibodies biotinylated using a synthetic Z-domain from protein A provide stringent in situ protein detection.

Antibody-based protein profiling on a global scale using immunohistochemistry constitutes an emerging strategy for mapping of the human proteome, which is crucial for an increased understanding of biological processes in the cell. Immunohistochemistry is often performed indirectly using secondary antibodies for detection, with the benefit of signal amplification. Direct immunohistochemistry instead brings the advantage of multiplexing; however, it requires labeling of the primary antibody.

Androgen deprivation therapy of self-identifying, help-seeking pedophiles in the Dunkelfeld.

Androgen deprivation therapy (ADT) is considered an effective strategy in sexual offender treatment. However, the evidence base concerning its effects on sexual arousal control is limited. Past research has focused almost exclusively on men in forensic contexts.

Covalent immunoglobulin labeling through a photoactivable synthetic Z domain.

Traditionally, labeling of antibodies has been performed by covalent conjugation to amine or carboxyl groups. These methods are efficient but suffer from nonspecificity, since all free and available amine/carboxyl groups have the possibility to react. This drawback may lead to uncontrolled levels and locations of the labeling.

High-throughput protein production--lessons from scaling up from 10 to 288 recombinant proteins per week.

The demand for high-throughput recombinant protein production has markedly increased with the increased activity in the field of proteomics. Within the Human Protein Atlas project recombinantly produced human protein fragments are used for antibody production. Here we describe how the protein expression and purification protocol has been optimized in the project to allow for handling of nearly 300 different proteins per week.

Affinity-based entrapment of the HER2 receptor in the endoplasmic reticulum using an affibody molecule.

Interference with the export of cell surface receptors can be performed through co-expression of specific affinity molecules designed for entrapment in the endoplasmic reticulum during the export process. We describe the investigation of a small (6 kDa) non-immunoglobulin-based HER2 receptor binding affibody molecule (Z(HER2:00477)), for use in affinity mediated entrapment of the HER2 receptor in the ER. Constructs encoding Z(HER2:00477) or a control affibody protein, with or without ER-retention peptide extensions (KDEL), were expressed in the HER2 over-expressing cell line SKOV-3.
