Intrinsic catalytic activity of rhodium nanoparticles with respect to reactive oxygen species scavenging: implication for diminishing cytotoxicity.

Noble metal nanoparticles (NPs) and their hybrids have demonstrated a strong potential to mimic the catalytic activity of natural enzymes and diminish oxidative stress. There is a large space to explore the intrinsic catalytic activity of Rh NPs with respect to reactive oxygen species (ROS) scavenging. We found that Rh NPs can quench HO, OH, O, O and inhibit lipid peroxidation under physiological conditions.

Comparing the effectiveness of two app-based number lines to teach price comparison to students with autism spectrum disorders.

Purpose: A number line consisting of Arabic numerals is a commonly used instructional tool for teaching price comparison. However, typical number lines lack concrete visual cues, which may benefit students with autism spectrum disorders (ASD) who have not yet mastered the representation of Arabic numerals.

Method: This study investigated the effects of additional visual cues (i.

Hearing Math: Algebra Supported eText for Students With Visual Impairments.

Supported eText for students with visual impairments in mathematics has a promising, emerging literature base, although little of the existing research focuses on implementation within a classroom setting. This qualitative study sought to understand the use of supported eText to deliver algebra to students with visual impairments enrolled in algebra mathematics courses. The study also sought to explore supported eText in contrast to students' traditional means of accessing an algebra text.

The reduced trabecular bone mass of adult ARKO male mice results from the decreased osteogenic differentiation of bone marrow stroma cells.

Male mice with androgen receptor knock-out (ARKO) show significant bone loss at a young age. However, the lasting effect of AR inactivation on bone in aging male mice remains unclear. We designed this study to evaluate the effect of AR on bone quality in aging male mice and to find the possible causes of AR inactivation contributing to the bone loss.
