There is a need for a psychometrically sound measure of the stigma experienced by diverse persons living with HIV/AIDS (PLHA). The goal of this study was to develop and evaluate a multidimentional measure of internalized HIV stigma that captures stigma related to treatment and other aspects of the disease among sociodemographically diverse PLHA. We developed a 28-item measure of internalized HIV stigma composed of four scales based on previous qualitative work. Internal consistency reliability estimates in a sample of 202 PLHA was 0.93 for the overall measure, and exceeded 0.85 for three of the four stigma scales. Items discriminated well across scales, and correlations of the scales with shame, social support, and mental health supported construct validity. This measure should prove useful to investigators examining in the role of stigma in HIV treatment and health outcomes, and evaluating interventions designed to mitigate the impacts of stigma on PLHA.

Via observational data from the Project on Human Development in Chicago Neighborhoods collected between 1994 and 2001, this study examined the degree to which neighborhood disorder, collective efficacy, and youth-centered institutional resources are directly associated with adolescents' depressive symptoms across time, and the mediating role of adolescents'neighborhood self-efficacy. Latent variable structural equation models were estimated among an unweighted representative sample of 1448 adolescents (59% male, mean age 15.19), across 79 neighborhoods in Chicago, to examine the direct effects of neighborhood disorder, collective efficacy, and availability of youth-centered resources at baseline (measured at timepoint 1; reported by an independent sample of Chicago adults) on adolescents' depressive symptoms (measured a timepoint 3), and the mediating effect of adolescents' neighborhood-anchored self-efficacy (measured at timepoint 2).

Biochips are widely applied to manipulate the geometrical morphology of stem cells in recent years. Patterned antenna-like pseudopodia are also probed to explore the influence of pseudopodia formation on gene delivery and expression on biochips. However, how the antenna-like pseudopodia affect gene transfection is unsettled and the underlying trafficking mechanism of exogenous genes in engineered single cells is not announced.

Background: Frustration intolerance (FI) is the belief that reality should meet our desires for ease, pleasure and comfort. Although extensively studied in adults, tools for measuring FI in children and adolescents are scarce. The Frustration Intolerance Scale for Students (FISS) was developed to fill this gap.

Many children with ASD exhibit difficulties with emotion regulation that greatly impair functioning. Certain intrinsic correlates of dysregulation have been identified in this population, but the search for potential environmental influences has been less fruitful. The current study examined several aspects of parenting as correlates of observed regulation in Autistic children, as measured in both parent-child and independent regulatory contexts.

Background: A biocompatible polymeric nanoparticle, TQ-PLGA-PF68, was developed through the interaction of the phytochemical thymoquinone (TQ) encapsulated in poly(L-lactide-co-glycolide)-b-poly(ethylene glycol) (PLGA-PEG) with Pluronics F68. So far, this combination has not been assessed on breast cancer cells resistant to anti-cancer drugs. Therefore, this study aimed to assess the cell death caused by TQ-PLGA-PF68 nanoparticles, particularly in resistant breast cancer cell lines expressing estrogen receptor (ER) positivity, such as TamR MCF-7.
