Older adults interact with a variety of technologies in the course of their daily activities and thus products should be designed to be used by people of varying ages.\n\nIn this article, we provide an overview of what psychology has to offer to the design of technology-from understanding what people need, to identifying their preferences for design characteristics, and to defining their capabilities and limitations that will influence technology interactions.\n\nWe identify how research in the field of psychology and aging has advanced understanding of technology interactions and how research on technology interactions can inform theories of aging.\n\nDesign for aging involves
understanding the unique capabilities and limitations of older adults; identifying their needs, preferences, and desires for technology in their lives; and involving them in the design process.”
“The current review describes
the phenomenology of A-1331852 cell line several common anxiety disorders in children and adolescents as they present in medical settings. Anxiety disorders and associated features in children are described, along with epidemiology, functional impairment, common somatic complaints, medical comorbidity, health care utilization, and presentation in general and in specialty pediatric Selleck LBH589 medical settings. Recommendations for clinical management in pediatric settings are presented, and evidence-based interventions and emerging treatments this website for pediatric anxiety disorders are described. The review concludes with a discussion of future research directions that may lead to increased recognition and improved management of anxiety disorders in pediatric medical settings.

“L-ascorbic acid (vitamin C) is an antioxidant and electron donor whose metabolism
in plants is under strict feedback control. The factors that influence L-ascorbic acid accumulation in staple crops are only partially understood. One way to gain insight into the regulation of L-ascorbic acid metabolism is to investigate the endogenous pathways in various genetic backgrounds and characterize their interactions with transgenes encoding relevant enzymes. In an initial step, we investigated the developmental profile of L-ascorbic acid accumulation in the endosperm of three diverse maize genotypes and a transgenic line expressing rice dehydroascorbate reductase, which enhances L-ascorbic acid recycling. We determined the transcript levels of all the key genes in the L-ascorbic acid metabolic pathways as well as the specific levels of ascorbic acid and dehydroascorbate. L-ascorbic acid levels were high 20 days after pollination and declined thereafter. We found significant genotype-dependent variations in the transcript levels of some genes, with particular complexity in the ascorbic acid recycling pathway.
