Functional Analyses of Oligonol by Novel Neutrophil Activity Measurement System

Calibrating a novel multi-sensor physical activity measurement system.

Advancing the field of physical activity (PA) monitoring requires the development of innovative multi-sensor measurement systems that are feasible in the free-living environment. The use of novel analytical techniques to combine and process these multiple sensor signals is equally important. This paper describes a novel multi-sensor 'integrated PA measurement system' (IMS), the lab-based method...

The measurement of neutrophil myeloperoxidase by flow cytochemistry is influenced by the pseudoperoxidase activity of hemoglobin.

Gulley et all have recently reported increased neutrophil myeloperoxidase (MPO) activity in 10 anemic patients demonstrated by the Technicon H* l instrument (Technicon Instruments Corp, Tarrytown, NY). Dash et ai2 have commented on this report for not considering the balance of smokers to nonsmokers. We would like to comment further on this report. It has been shown by us that the neutrophil MP...

Longitudinal measurement of physical activity using a novel automated system to explore early stage functional recovery after stroke

Heterogeneity of human neutrophil phagolysosomes: functional consequences for candidacidal activity.

Opsonized yeast phase Candida albicans, incubated with human neutrophils, are internalized into two classes of phagosomes. One class, termed "unsealed vacuoles," comprises approximately 40% of the total and maintains functional communication to the cell's exterior that is sufficient to permit ingress of dyes, such as trypan or methylene blue. The remaining cell-associated yeasts are contained i...

Neutralization of heparin activity by neutrophil lactoferrin.

Lactoferrin is a prominent component of neutrophil secondary granules, and its blood concentration is increased in certain inflammatory diseases. In contrast to the well-described biochemical characterization of lactoferrin as an iron-binding protein, its physiologic role in the regulation of inflammation and other host defense mechanisms is unclear. In this report, we provide evidence that lac...
