Validity and reliability of the Huet questionnaire to assess maximal oxygen uptake

Research substantiates children of parents with mental disorders including substance abuse face increased risk for emotional and behavioral problems. Although evidence suggests that support programs for children enhance resiliency, recruiting children to these groups remains problematic. This study identifies successful recruitment strategies for prevention programs for children of parental mental illness. The participants were recruited from an international network of researchers. E-mail invitations requested that researchers forward a web-based questionnaire to five colleagues with recruitment experience. Forty-five individuals from nine countries practicing in mental health responded. Descriptive statistics and qualitative content analysis techniques were used. Results: Schools, adult, and youth mental health services were recruitment sources. Nine themes were identified: Relationships, diversified information output, logistics, program consistency, family involvement, recruitment through adults, stigma, recruiting locations, social media. Recruitment barriers were: stigma, inadequate knowledge about parental mental illness and limited time. Transportation to programming was an essential component of successful recruitment

Synthesis and evaluation of amides surrogates of dopamine D3 receptor ligands.

International audienceIsosteric replacement of the amide function and modulation of the arylpiperazine moiety of known dopamine D3 receptor ligands led to potent and selective compounds. Enhanced bioavailability and preferential brain distribution make compound 6c a good candidate for pharmacological and clinical evaluation

Dual and Opposite Effects of hRAD51 Chemical Modulation on HIV-1 Integration

The cellular DNA repair hRAD51 protein has been shown to restrict HIV-1 integration both in vitro and in vivo. To investigate its regulatory functions, we performed a pharmacological analysis of the retroviral integration modulation by hRAD51. We found that, in vitro, chemical activation of hRAD51 stimulates its integration inhibitory properties, whereas inhibition of hRAD51 decreases the integration restriction, indicating that the modulation of HIV-1 integration depends on the hRAD51 recombinase activity. Cellular analyses demonstrated that cells exhibiting high hRAD51 levels prior to de novo infection are more resistant to integration. On the other hand, when hRAD51 was activated during integration, cells were more permissive. Altogether, these data establish the functional link between hRAD51 activity and HIV-1 integration. Our results highlight the multiple and opposite effects of the recombinase during integration and provide new insights into the cellular regulation of HIV-1 replication
