• The determination of total body water by measurements of the distribution A'olume of antipyrine was originally proposed by Soberman, Brodie, et al. The applicability of the method has been extended by the use of the more easily determined aeetylaminoantipyrine. It has also been suggested' that the iodinated derivative of antipyrine labeled with I might be a satisfactory substitute for the par...

Total body water was measured using tritium in 30 males and 30 females. It was found that total body water could be predicted from height and weight, and formulae for both males and females have been produced with multiple correlation coefficients (r) of 0.95 and 0.96 respectively. The predicted total body water was found to be very closely related to the predicted surface area giving correlati...

l. Ten captive Myotis thysanodes ingested an average of 5.05 kcal/ day and egested 0.47 kcal/day with a mean energy utilization of 90.8 per cent. 2. One captive M. lucifugus ingested 4.15 kcaljday and egested 0.37 kcal/day with an energy utilization of 91.2 per cent. 3. M. thysanodes gained an average of 2.77 cm3/day of water and lost an average of 2.86 cma/day. This represents a water turnover...

In evaluating the renal mechanisms responsible for the generation of the dysnatremias, an analysis of free water clearance (FWC) and electrolyte-free water clearance (EFWC) is often utilized to characterize the rate of urinary free water excretion in these disorders. Previous analyses of FWC and EFWC have failed to consider the relationship among plasma water Na(+) concentration ([Na(+)](pw)), ...

Measurement of body composition is an important part of any assessment of health or fitness. Hydrostatic weighing is generally accepted as the most reliable method for the measurement of body fat content, but is inconvenient. Electrical impedance analysers have recently been proposed as an alternative to the measurement of skinfold thickness. Both these latter methods are convenient, but give v...

Scorpions of the Family Buthidae have lower water loss rates (WLR) and enhanced osmoregulatory capacities in comparison with sympatric species of F. Scorpionidae. In this study we followed changes in water content of different body compartments in four scorpion species under prolonged desiccation conditions. The high initial WLR previously reported for Scorpionidae result in rapid depletion of ...

There is a paucity of data on differences between methods for the assessment of body composition in elderly subjects. Studies on younger adults suggest that such differences are of some practical significance at the individual level. In the present study the following methods of estimating percentage body fatness (BF%) were compared in healthy elderly men and women (mean age 70 (SD 6) years: de...

Watermarking consists of hiding of information within a multimedia element such as an image, a text, music or a video clip. Hiding information within other information is called steganography. A TV station’s logo may serve as an example for perceptible information. Steganographical methods are needed to integrate non-perceptible information: that means this information is hidden within a multim...

The main purpose of the present study was to investigate the effect of 16 weeks of resistance training (RT) on body water in men and women. Thirty men (22.7 ± 4.4 years, 68.4 ± 9.0 kg and 174.5 ± 6.6 cm) and 34 women (22.7 ± 4.1 years, 58.8 ± 11.9 kg and 162.6 ± 6.2 cm) underwent progressive RT for 16 weeks (2 phases, 8 weeks each), 3 times per week, that consisted of 10-12 whole body exercises...
