Informant sex/gender moderates associations between reported functioning and memory performance in Mexican American adults.

In neuropsychological evaluations, assessing cognitive functioning is often achieved using objective neuropsychological measures, whereas subjective informant reports are typically obtained to determine manifest daily functioning. Informant reports of participant functioning and their associations with objective participant performance on neuropsychological testing have been shown to vary based on informant characteristics. However, associations among informant characteristics, reported functioning, and neuropsychological performance have not been adequately examined with Mexican American or other Hispanic/Latino samples, despite these populations' disproportionately higher rates of dementia due to Alzheimer's disease and related disorders.

Preparation of Extracellular Matrices Produced by Cultured and Primary Fibroblasts.

Fibroblasts secrete and organize extracellular matrix (ECM), which provides structural support for their adhesion, migration, and tissue organization, besides regulating cellular functions such as growth and survival. Cell-to-matrix interactions are vital for vertebrate development. Disorders in these processes have been associated with fibrosis, developmental malformations, cancer, and other diseases.

TRPC6 channel translocation into phagosomal membrane augments phagosomal function.

Defects in the innate immune system in the lung with attendant bacterial infections contribute to lung tissue damage, respiratory insufficiency, and ultimately death in the pathogenesis of cystic fibrosis (CF). Professional phagocytes, including alveolar macrophages (AMs), have specialized pathways that ensure efficient killing of pathogens in phagosomes. Phagosomal acidification facilitates the optimal functioning of degradative enzymes, ultimately contributing to bacterial killing.

Cell-based potassium ion channel screening using the FluxOR assay.

FluxOR technology is a cell-based assay used for high-throughput screening measurements of potassium channel activity. Using thallium influx as a surrogate indicator of potassium ion channel activity, the FluxOR Potassium Ion Channel Assay is based on the activation of a novel fluorescent dye. This indicator reports channel activity with a large fluorogenic response and is proportional to the number of open potassium channels on the cell, making it extremely useful for studying K(+) channel targets.
