Hydrogen isotope fractionation in ammonia-oxidizing archaea
… the relationship between δ2H of the growth water (δ2HH2O) and δ2HBPcren, and the variability of 2εL/W depending on temperature, pH and salinity were investigated. The results indicate that Nitrososphaeria exhibit a narrow range of 2εL/W (BPcren: -257‰ to -307‰) at optimal growth conditions. …

Muscle Strength and Body Cell Mass in Postmenopausal Women
… also been observed that total body potassium and intracellular water (ICW) decrease with age, reflecting a loss of body cell mass (BCM), 60% of which is the skeletal muscle. It is generally accepted that traditional high-intensity strength training (ST) regimens can not only attenuate, but in some …

Biological Water: Properties and Role in Muscle Function and Development
Water is the most abundant substance on planet Earth and present in large part of our daily lives. Despite such abundance, liquid water still remains mysterious for we do not understand its structure. Similarly, biological systems are largely composed of water and life is believed to have …

Measuring compositional and growth properties of single cells
… to quantify cellular dry mass, dry density and water content. It is based on weighing the same cell first in a water-based fluid and subsequently in a deuterium oxide-based fluid, which rapidly exchanges the intracellular water content. Correlations between dry density and cellular proliferation …

THE FREQUENCY-DEPENDENCE OF THE NMR LONGITUDINAL RELAXATION RATE, T(1)(-1), OF WATER IN CYSTS OF THE BRINE SHRIMP (ARTEMIA)
… NMR spin-lattice relaxation rate, T(,1)('-1), of water is independent of the Larmor frequency, (omega)/2(pi), in the normal rf range. However, T(,1)('-1) of intracellular water in biological systems, which accounts for as much as 80% of the cell mass, is frequency-dependent. This indicates that …

Selenite influence on calcium metabolism of the rat lens
… in a 2.5-fold increase only of extracellular water. In in vitro selenite-treated lenses, however, there is a 2.6-fold increase in extracellular water and a 1.8-fold increase of intracellular water. Selenite treatment of the lenses in vivo and in vitro causes a greater influx of calcium into …

Study on the processing technology of iced roasted sweet potato and its sensory characteristics and nutritional peculiarities
… NMR results showed that roasting changes the water distribution, the proportion of free water increased and relaxation times (T2) were decreased after roasting process. Thirdly, the effects of different freezing temperature on structure, moisture distribution, sensory, and nutritional …

Malnutrizione proteico-energetica, sarcopenia e disidratazione nella popolazione senile sana e affetta da patologie
… p=0.002). The evaluation of extracellular water/intracellular water ratio was accurate (ROC areas between 0.83 and 0.96) and similarly performed by the two procedures (p=0.829). Classic and specific BIVA detected significant differences between sarcopenic and nonsarcopenic individuals. …

Modeling the Production of Microalgal Biodiesel
… biological properties including lipid fraction, intracellular water content, and growth rate are among the most influential with respect to one or more of the KPI's. Trend analyses of several of the anaerobic digester operating parameters show that factors affecting biogas production have much …
