Massive bubble formation after diving can lead to decompression sickness (DCS). During dives with hydrogen as a diluent for oxygen, decreasing the body's H2 burden by inoculating hydrogen-metabolizing microbes into the gut reduces the risk of DCS. So we set out to investigate if colonic fermentation leading to endogenous hydrogen production promotes DCS in fasting rats. Four hours before an exp...

KELLY, KEITH A., CHARLES F. CODE, AND LILA R. ELVEBACK. Patterns uf canine gastric electrical activity. Am. J. Physiol. 2 17C2) : 46 l-470. 1969.~Eight electrodes were implanted serially from the fundus to the pylorus on the gastric wall of 12 dogs. After recovery, electrical activity was recorded during fasting and after gastric-balloon distention and gastric instillation of water and cottonse...

We investigated the applicability of (2)H to measure the amount of body water (TBW) and water fluxes in relation to diet type and level of food intake in a mollusk-eating shorebird, the Red Knot (Calidris canutus). Six birds were exposed to eight experimental indoor conditions. Average fractional (2)H turnover rates ranged between 0. 182 day(-1) (SD = 0.0219) for fasting birds and 7.759 day(-1)...

The physiological effects of dietary fibres in humans are due to their physico-chemical properties. However, it is difficult to predict these effects simply by measuring certain characteristics in vitro. Studies in human subjects are still required to assess the effectiveness of new substrates. The aim of the present study in healthy human subjects was to evaluate the effects of two novel fibre...

BACKGROUND High oxalate intake resulting from consuming supplemental doses of cinnamon and turmeric may increase risk of hyperoxaluria, a significant risk factor for urolithiasis. OBJECTIVE This study assessed urinary oxalate excretion from supplemental doses of cinnamon and turmeric as well as changes in fasting plasma glucose, cholesterol, and triacylglycerol concentrations. DESIGN Eleven...

OBJECTIVES To assess the health risks associated with consumption of drinking water with elevated nickel concentration in a NSW country town named Sampleton. METHODS We used enHealth Guidelines (2002) as our risk assessment tool. Laboratory test results for nickel in water samples were compared with the Australian Drinking Water Guidelines 2004 and the World Health Organization's (WHO) Guidel...

The preparation of the patient is a crucial time as it can contribute to the success of the bronchoscopic examination. First and foremost, preparation provides the patient with correct information regarding the procedure by which bronchoscopy is performed and informs him/her of sensations that may be felt. The anxiety and worry manifested by the majority of patients undergoing bronchoscopic exa...

Over centuries, mankind had to deal with a steadily changing food supply. Depending on seasonal fluctuations or greater natural disasters, either plenty or little food was available. As a consequence, people in different areas of the world developed sophisticated strategies, e.g., seasonal fasting, to handle and overcome these problems. Possibly, in these early days, people discovered also the ...
