A Multi-Week Assessment of a Mobile Exergame Intervention in an Elementary School.

Background: Exergaming is potentially useful to promote physical activity in children; however, long-term effectiveness is unclear. MobileKids Monster Manor (MKMM) is a mobile exergame developed with the help of young advisors. The game wirelessly transmits physical activity data from an accelerometer to a mobile device.

Evaluation of a Novel Mobile Exergame in a School-Based Environment.

Physical inactivity is increasing among children globally and has been directly linked to the growing problems of overweight and obesity. We aim to assess the impact of a new mobile exergame, MobileKids Monster Manor (MKMM), in a school-based setting. MKMM, developed with input from youth to enhance physical activity, is wirelessly connected to an accelerometer-based activity monitor.

Metabolic requirements of interactive video game cycling.

Background: Interactive video game exercise leads to improved exercise adherence and health-related physical fitness in comparison to traditional stationary cycling. It has been postulated that interactive video game exercise has greater metabolic requirements than traditional cycling; however, this has not been tested to date.

Purpose: To examine the metabolic requirements of interactive video game exercise in comparison to traditional stationary cycling at matched incremental workloads.

Enzyme-linked immunosorbent assay for measurement of antibody responses to Dirofilaria immitis in experimentally infected dogs.

The chronology of the antibody response to Dirofilaria immitis was measured in 2 groups of experimentally infected Beagle dogs. An enzyme-linked immunosorbent assay (ELISA), using a semipurified, adult D immitis-derived antigen was used to quantitate antibody levels. Group A consisted of 4 dogs inoculated once with D immitis infective larvae, 4 dogs inoculated twice with D immitis infective larvae, and 4 noninoculated dogs.

Infection of cultured human type II pneumonocytes with certain respiratory viruses.

Human type II alveolar pneumonocytes were grown either as monolayers derived from a clone or as organotypic cultures of fetal lung. The type II cells in these cultures retained in their cytoplasm multilamellar bodies which were morphologically identical to similar organelles present in type II cells of intact human fetal and adult lung. A number of respiratory viruses infected the cells and produced a cytopathic effect in the cultures.

Clones of cells from a human embryo lung: their growth and susceptibility to respiratory viruses.

Colonies of cells were obtained from human fetal lung tissue and exposed to recently isolated respiratory viruses. There was a considerable variation in the number of rounded cells found in different colonies exposed to rhinovirus types 2 and 9 (RV2 and 9), human coronavirus 229E (HCV), adenovirus type 3 (Ad3) and respiratory syncytial virus (RSV). Smaller colonies had more rounded cells than larger colonies.

Selection of new human foreskin fibroblast cell strains for interferon production.

The aim of this work has been to isolate and characterize new diploid cell strains, suitable for large-scale production of human fibroblast interferon. Twenty cell strains were isolated from individual neonatal foreskins obtained with the informed consent of the donors' parents. The techniques employed for the isolation of the cell strains were aimed at obtaining the highest possible yield of normal diploid cells, free of contaminating microorganism and viruses.
