Criminal victimisation in people with severe mental illness: a multi-site prevalence and incidence survey in the Netherlands.
PLoS ONE
PUBLISHED: 01-01-2014
Show Abstract
Hide Abstract
Although crime victimisation is as prevalent in psychiatric patients as crime perpetration (and possibly more so), few European figures for it are available. We therefore assessed its one-year prevalence and incident rates in Dutch severely mentally ill outpatients, and compared the results with victimisation rates in the general population.

Psychometric Properties of the Dutch Version of the Self-Sufficiency Matrix (SSM-D).
Community Ment Health J

Hide Abstract
Measuring treatment outcomes can be challenging in patients who experience multiple interlinked problems, as is the case in public mental health care (PMHC). This study describes the development and psychometric properties of a Dutch version of the self-sufficiency matrix (SSM-D), an instrument that measures outcomes and originates from the US. In two different settings, clients were rated using the SSM-D in combination with the Health of the Nation Outcome Scales (HoNOS) and the Camberwell assessment of need short appraisal schedule (CANSAS). The results provided support for adequate psychometric properties of the SSM-D. The SSM-D had a solid single factor structure and internal consistency of the scale was excellent. In addition, convergent validity of the SSM-D was indicated by strong correlations between HoNOS and CANSAS, as well as between several subdomains. Further research is needed to establish whether the results presented here can be obtained in other PMHC settings.

Monoclonal antibody binding-site diversity assessment with a cell-based clustering assay.
J. Immunol. Methods

Hide Abstract
The diversity of a panel of antibodies that target a specific antigen can be established in various assay formats. In conventional epitope binning assays purified antibodies are tested in a pairwise manner: two antibodies that compete with each other for binding to an antigen are grouped into the same cluster or bin, while they are assigned to two different clusters when they do not compete. Here we present a high throughout assay that enables grouping of crude hybridoma supernatants without a need for antibody purification. In addition, the assay does not require recombinant protein, because it is conducted on cells that express the antigen of interest. Hence, one can use the antibody-clustering assay for cell surface proteins that are not amenable to purification. Heavy chain variable region (VH) sequencing shows that VH composition within clusters is conserved. Finally, the assay is in good agreement with a conventional epitope binning assay with purified antigen.

Victimization of patients with severe psychiatric disorders: prevalence, risk factors, protective factors and consequences for mental health. A longitudinal study.
BMC Public Health
PUBLISHED: 10-04-2010
Show Abstract
Hide Abstract
Victimization among people with a Severe Mental Illness is a common phenomenon. The objectives of this study proposal are: to delineate the extent and kind of victimization in a representative sample of chronic psychiatric patients; to contribute to the development and validation of a set of instruments registering victimization of psychiatric patients; to determine risk factors and protective factors; and to gain insight into the possible consequences of victimization.

Paracrine Hedgehog signaling in cancer.
Cancer Res.
PUBLISHED: 07-28-2009
Show Abstract
Hide Abstract
Ligand-dependent and ligand-independent activation of the Hedgehog (Hh) signaling pathway is involved in tumorigenesis. The importance of mutations in Hh pathway components leading to constitutive signaling has been well established in basal cell carcinoma and medulloblastoma. However, the role of ligand-driven Hh pathway activation in cancer remains to be established. Three recent articles support a model in which, in the absence of mutations in the Hh pathway, Hh ligands expressed by a subset of epithelial cancers, including colon, pancreatic, and ovarian cancer, promote tumor growth indirectly by activating Hh signaling in the surrounding stroma, which, in turn, provides a more favorable environment for tumor growth. These data have important implications for the use of Hh pathway inhibitors currently in development and for selection of tumors likely to respond to such inhibitors.

The mammalian Cos2 homolog Kif7 plays an essential role in modulating Hh signal transduction during development.
Curr. Biol.
PUBLISHED: 03-31-2009
Show Abstract
Hide Abstract
The Hedgehog (Hh) signaling pathway regulates development in animals ranging from flies to humans. Although its framework is conserved, differences in pathway components have been reported. A kinesin-like protein, Costal2 (Cos2), plays a central role in the Hh pathway in flies. Knockdown of a zebrafish homolog of Cos2, Kif7, results in ectopic Hh signaling, suggesting that Kif7 acts primarily as a negative regulator of Hh signal transduction. However, in vitro analysis of the function of mammalian Kif7 and the closely related Kif27 has led to the conclusion that neither protein has a role in Hh signaling. Using Kif7 knockout mice, we demonstrate that mouse Kif7, like its zebrafish and Drosophila homologs, plays a role in transducing the Hh signal. We show that Kif7 accumulates at the distal tip of the primary cilia in a Hh-dependent manner. We also demonstrate a requirement for Kif7 in the efficient localization of Gli3 to cilia in response to Hh and for the processing of Gli3 to its repressor form. These results suggest a role for Kif7 in coordinating Hh signal transduction at the tip of cilia and preventing Gli3 cleavage into a repressor form in the presence of Hh.

Artemis and nonhomologous end joining-independent influence of DNA-dependent protein kinase catalytic subunit on chromosome stability.
Mol. Cell. Biol.

Hide Abstract
Deficiency in both ATM and the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) is synthetically lethal in developing mouse embryos. Using mice that phenocopy diverse aspects of Atm deficiency, we have analyzed the genetic requirements for embryonic lethality in the absence of functional DNA-PKcs. Similar to the loss of ATM, hypomorphic mutations of Mre11 (Mre11(ATLD1)) led to synthetic lethality when juxtaposed with DNA-PKcs deficiency (Prkdc(scid)). In contrast, the more moderate DNA double-strand break response defects associated with the Nbs1(DeltaB) allele permitted viability of some Nbs1(DeltaB/DeltaB) Prkdc(scid/scid) embryos. Cell cultures from Nbs1(DeltaB/DeltaB) Prkdc(scid/scid) embryos displayed severe defects, including premature senescence, mitotic aberrations, sensitivity to ionizing radiation, altered checkpoint responses, and increased chromosome instability. The known functions of DNA-PKcs in the regulation of Artemis nuclease activity or nonhomologous end joining-mediated repair do not appear to underlie the severe genetic interaction. Our results reveal a role for DNA-PKcs in the maintenance of S/G(2)-phase chromosome stability and in the induction of cell cycle checkpoint responses.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
