Evaluation of immobility time for sleep latency in actigraphy

Abstract BACKGROUND: Actigraphy has become an important tool in sleep research, however, most actigraphic models have had little evaluation of their sleep scoring software. Some reports have described poor agreement of actigraph and polysomnogram (PSG) results. In this study, we examined the accuracy of the Actiwatch-L instrument with Actiware((R)) software version 5.0 (Minimitter-Respironics, Bend, Oregon). […]

Supplemental feedings increase self-selected work output during wildfire suppression

Abstract PURPOSE: The purpose of this study was to determine the impact of supplemental feeding strategies on self-selected activity during wildland fire suppression. METHODS: Seventy-six wildland firefighters were studied in three experiments for three fire seasons. During the first two seasons, subjects consumed, in addition to their sack lunch, 1) liquid carbohydrate (CHO) (200 mL.h, […]

Telemetry for Biosensor Systems

Excerpt This chapter will provide an overview of radio frequency (RF) telemetry systems by examining the design requirements of two contrasting systems: a wireless system designed to support Fast Scan Cyclic Voltammetry (FSCV) and a wireless system designed to support selective biosensors. Traditionally, RF design and analog circuit design were very complicated endeavors. Component interactions […]

CCK-8 and PGE1: central effects on circadian body temperature and activity rhythms in rats

Abstract Cholecystokinin-octapeptide (CCK-8) has been shown to possess an acute thermogenic and hyperthermic action when given intracerebroventricularly in slightly restrained rats. To substantiate the febrile nature of that hyperthermia freely moving animals should be used and together with body core temperature, at least one behavioral parameter, such as general activity, should also be recorded. In […]

Genetic Models in Applied Physiology. Differential role of nitric oxide synthase isoforms in fever of different etiologies: studies using Nos gene-deficient mice.

Abstract Male C57BL/6J mice deficient in nitric oxide synthase (NOS) genes (knockout) and control (wild-type) mice were implanted intra-abdominally with battery-operated miniature biotelemeters (model VMFH MiniMitter, Sunriver, OR) to monitor changes in body temperature. Intravenous injection of lipopolysaccharide (LPS; 50 microg/kg) was used to trigger fever in response to systemic inflammation in mice. To induce […]
