Meeting Report: Alternatives for Developmental Neurotoxicity Testing

Developmental neurotoxicity testing (DNT) is perceived by many stakeholders to be an area in critical need of alternatives to current animal testing protocols and guidelines. To address this need, the Johns Hopkins Center for Alternatives to Animal Testing (CAAT), the U.S. Environmental Protection Agency, and the National Toxicology Program are collaborating in a program called TestSmart DNT, the goals of which are to: (a) develop alternative methodologies for identifying and prioritizing chemicals and exposures that may cause developmental neurotoxicity in humans; (b) develop the policies for incorporating DNT alternatives into regulatory decision making; and (c) identify opportunities for reducing, refining, or replacing the use of animals in DNT. The first TestSmart DNT workshop was an open registration meeting held 13–15 March 2006 in Reston, Virginia. The primary objective was to bring together stakeholders (test developers, test users, regulators, and advocates for children’s health, animal welfare, and environmental health) and individuals representing diverse disciplines (developmental neurobiology, toxicology, policy, and regulatory science) from around the world to share information and concerns relating to the science and policy of DNT. Individual presentations are available at the CAAT TestSmart website. This report provides a synthesis of workgroup discussions and recommendations for future directions and priorities, which include initiating a systematic evaluation of alternative models and technologies, developing a framework for the creation of an open database to catalog DNT data, and devising a strategy for harmonizing the validation process across international jurisdictional borders

Exploratory Research in Public Social Service Agencies: As Assessment of Dissemination and Utilization

The purpose of this study was to investigate how nine exploratory research studies were disseminated and utilized by social services agencies in four California counties. It is based on in-depth interviews with sixteen key social service agency staff members in four counties who were involved in the planning and implementation of the research projects. While reports were disseminated internally to agency management staff, the results revealed that fewer were shared with supervisory and line staff. All of the studies influenced agency thinking and, in some cases, specific agency decisionmaking processes. The key factors influencing the utilization of research included: (a) characteristics of the findings and recommendations, (b) specific project situations, (c) practitioner and researcher characteristics, and (d) communication. Implications for future research and practice are identified in relationship to improving the scope of work, strengthening the agency-researcher partnership, developing a research networking program, and increasing media strategies for bringing research to the marketplace

Social reintegration programs for former inmates in Brazil: is there a gender perspective?

Com o aumento do número de mulheres privadas de liberdade em todo o mundo, a importância da implantação de estratégias específicas que devem ser aplicadas ao suporte oferecido a essas mulheres são importantes medidas sociais. O objetivo deste estudo é analisar a oferta dos recursos para a reinserção social de egressos do sistema prisional brasileiro, com o recorte de gênero. A proposta é realizar uma análise documental sobre estratégias governamentais e não governamentais direcionadas para este público, com recorte de gênero, por meio de uma matriz analítica pelo período compreendido entre 2020 e 2021. Os resultados mostram que há no país diversos programas voltados à reinserção social de egressos do sistema prisional, entretanto poucos apresentam um recorte de gênero. O tema reinserção social e sistema prisional foi identificado em 84 notícias em sítios dos organismos governamentais visitados, sendo 20 federais e 64 estaduais. Em 11 organismos internacionais atuando no Brasil e em 12 ONGs, somente seis apresentaram recorte de gênero. O desafio do sistema penitenciário brasileiro é incluir a abordagem de cidadania e dignidade humana no sistema prisional, incluindo uma abordagem da questão de gênero.With the increasing number of women deprived of liberty worldwide, implementing specific strategies that should be applied to the support offered to these women are essential social measures. This study aims to analyze the supply of resources for the social reintegration of former inmates of the Brazilian prison system from a gender perspective. We propose to conduct a documentary analysis on governmental and non-governmental strategies aimed at this audience, with a gender perspective, through an analytical matrix for the 2020-2021 period. The results show several programs in the country aimed at the social reintegration of former prisoners; however, few have a gender perspective. The theme of social reintegration and the prison system was identified in 84 news items on government agencies’ websites, 20 of which were federal and 64 state, in 11 international organizations operating in Brazil, and 12 NGOs. Only six had a gender profile. The challenge for the Brazilian penitentiary system is to introduce the citizenship and human dignity approach in the prison system, including an approach to the gender issue.Fil: Barbosa Miranda, Raquel.

Assessing probe-specific dye and slide biases in two-color microarray data

A primary reason for using two-color microarrays is that the use of two samples labeled with different dyes on the same slide, that bind to probes on the same spot, is supposed to adjust for many factors that introduce noise and errors into the analysis. Most users assume that any differences between the dyes can be adjusted out by standard methods of normalization, so that measures such as log ratios on the same slide are reliable measures of comparative expression. However, even after the normalization, there are still probe specific dye and slide variation among the data. We define a method to quantify the amount of the dye-by-probe and slide-by-probe interaction. This serves as a diagnostic, both visual and numeric, of the existence of probe-specific dye bias. We show how this improved the performance of two-color array analysis for arrays for genomic analysis of biological samples ranging from rice to human tissue.We develop a procedure for quantifying the extent of probe-specific dye and slide bias in two-color microarrays. The primary output is a graphical diagnostic of the extent of the bias which called ECDF (Empirical Cumulative Distribution Function), though numerical results are also obtained.We show that the dye and slide biases were high for human and rice genomic arrays in two gene expression facilities, even after the standard intensity-based normalization, and describe how this diagnostic allowed the problems causing the probe-specific bias to be addressed, and resulted in important improvements in performance.
