Conventional indicator dilution techniques for measuring body fluid volume are laborious, expensive, and highly invasive. Bioimpedance spectroscopy (BIS) may be a useful alternative due to being rapid, minimally invasive, and allowing repeated measurements. BIS has not been reported in mice; hence we examined how well BIS estimates body fluid volume in mice. Using C57/Bl6 mice, the BIS system d...

OBJECTIVE The present study aimed to determine the validity of simple epidemiological and clinical methods for the assessment of body fatness in preschool children. METHODS In 89 children (42 boys, 47 girls; mean age 4.1 SD 1.3y) measures of body fatness were made using total body water (TBW), dual energy x-ray absorptiometry (DXA), air displacement plethysmography (BODPOD) and skinfold thick...

BACKGROUND The currently available pharmacokinetic models for fentanyl were derived from normal weight patients and were not scaled to body weight. Their application to obese patients may cause overprediction of the plasma concentration of fentanyl. This study examined the influence of body weight on the predictive accuracy of two models (Anesthesiology 1990; 73:1091-102 and J Pharmacol Exp The...

Team-based work (TBW) plays a crucial role in the success and quality of public services. In context Spanish sector, our study evaluates if low level hierarchical distance (HD) organizations condition employees’ commitment (EC) as well TBW, assessed terms participation consensus among team members. Simultaneously, we evaluated to what extent EC help enhance TBW. Employing sample 213 government ...

We calculate the effect of new CP violating interactions parameterized by an anomalous tbW coupling on CP -odd observables in B decays. We find that couplings consistent with current bounds induce observable effects in some CP asymmetries that will be measured in B-factories. The new effects are sufficiently large that they can actually test specific models that give rise to these tbW interacti...

BACKGROUND The degree of volume depletion in severe malaria is currently unknown, although knowledge of fluid compartment volumes can guide therapy. To assist management of severely ill children, and to test the hypothesis that volume changes in fluid compartments reflect disease severity, we measured body compartment volumes in Gabonese children with malaria. METHODS AND FINDINGS Total body ...

Total body water (TBW) is consistently 70% of the lean body weight across age and sex ranges but varies as a percentage of actual bodyweight between groups and individuals owing to varied deposition of adipose tissue, which contains less water than muscle. TBW is 75% of total body weight in neonates, 70% in infants and 45% in the elderly. The average adult male (70 kg) has 60% of total body wei...

Bioimpedance spectroscopy (BIS) is a technique of interest in the study of human pregnancy because it can assess extracellular (ECW), intracellular (ICW), and total body water (TBW) as ECW plus ICW. The technique requires appropriate resistivity coefficients and has not been sufficiently evaluated during the reproductive cycle. Therefore, in a methodological study, we estimated ECW, ICW, and TB...

The normalization of GFR to a standardized body-surface area of 1.73 m(2) impedes comparison of GFR across individuals of different genders, heights, or weights. Ideally, GFR should be normalized to a parameter that best explains variation in GFR. Here, we measured true GFR by iohexol clearance in a representative sample of 1627 individuals from the general population who did not have diabetes,...

Abstract Maintaining balance involves the combination of sensory signals from visual, vestibular, proprioceptive, and auditory systems. However, physical biological constraints ensure that these are perceived slightly asynchronously. The brain only recognizes them as simultaneous when they occur within a period time called temporal binding window (TBW). Aging can prolong TBW, leading to uncerta...
