The circadian system orchestrates the temporal organization of many aspects of physiology, including metabolism, in synchrony with the 24 hr rotation of the Earth. Like the metabolic system, the circadian system is a complex feedback network that involves interactions between the central nervous system and peripheral tissues. Emerging evidence suggests that circadian regulation is intimately li...

In ankylosing spondylitis a simple method of measuring and recording spinal deformity is of value in assessing progress. Methods in use include serial photography, serial strip plaster-of-paris casts, and lead-moulding tracing the outline on to paper. The apparatus described below is cheaper, less cumbersome, and more simple and convenient to use. Construction It consists of an upright, 6 ft. 3...

The purpose of this study was to examine whether the resistance of the peak flow meter influences its recordings. One hundred and twelve subjects, (healthy nonsmokers and smokers and subjects with lung diseases) performed three or more peak expiratory flow (PEF) manoeuvres through a Fleisch pneumotachograph with and without a mini-Wright peak flow meter added in random order as a resistance in ...

OBJECTIVE To compare β-hydroxybutyrate (BHB) and glucose concentrations measured with a dual-purpose point-of-care (POC) meter designed for use in humans and a laboratory biochemical analyzer (LBA) to determine whether the POC meter would be reliable for on-farm measurement of blood glucose and BHB concentrations in sheep in various environmental conditions and nutritional states. ANIMALS 36 ...

INTRODUCTION Studies in US Hispanic adults indicate no deleterious association between obesity and death. We tested the hypothesis that accounting for weight history would provide more insight into this nonassociation. METHODS We used the National Health and Nutrition Examination Survey (NHANES) to examine associations between maximum lifetime body mass index (BMI) and all-cause and cause-spe...

Flavonoids, present in high levels in cranberries, are potent bioactives known for their health-promoting benefits, but cranberry beverages (CB) are not typically recommended as part of a healthy diet. We examine the association between CB consumption with macronutrient intake and weight status. Data for US adults (≥19 years, n = 10,891) were taken from the National Health and Nutrition Examina...

OBJECTIVES Circulating 25-hydroxyvitamin D (25-OHD) is associated with improved cancer prognosis in some studies, yet it may be a surrogate marker for physical activity. We investigated the associations of leisure-time physical activity (LTPA) with circulating 25-OHD levels in cancer survivors, and determined whether associations differ by indoor and outdoor activity. DESIGN Cross-sectional s...

OBJECTIVES The mercury sphygmomanometer has been the gold standard used for obtaining blood pressure (BP) for the National Health and Nutrition Examination Survey (NHANES) from 1960 to the present. However, due to environmental concerns and an increased use of automated oscillometric BP devices, NHANES has been exploring an alternative to using the standard mercury sphygmomanometer (mercury) to...
