Quasielastic and inelastic neutron scattering have been highlighted as excellent tools for studying the hydration of cement components. Here, the complimentary application of inelastic and time-resolved quasielastic neutron scattering to investigate the reaction kinetics during the crucial first 24 h of hydration will be highlighted. Some recent results include the interaction of tricalcium and...
BACKGROUND Contrast-induced nephropathy (CIN) is the third most common cause of hospital-acquired kidney injury and is related to increased long-term morbidity and mortality. Adequate intravenous (IV) hydration has been demonstrated to lessen its occurrence. Oral (PO) hydration with water is inexpensive and readily available but its role for CIN prevention is yet to be determined. METHODS Pub...
The characteristic relaxation time τ of protein hydration water exhibits a strong hydration level h dependence. The dynamic crossover is observed when h is higher than the monolayer hydration level hc=0.2-0.25 and becomes more visible as h increases. When h is lower than hc, τ only exhibits Arrhenius behavior in the measured temperature range. The activation energy of the Arrhenius behavior is ...
There are several questions about hydration in terminal care: the discussion about whether or not, and if yes how much and by which route? Shows hydration any benefits regarding survival and symptom-control? Are there side-effects of hydration? The article tries to give an overview rather than a review over the literature of the last 10 years since there is no evidence about this topic. Three s...
The apparent molar compressibilities φK of aqueous 3-1 electrolyte solutions have been determined from ultrasound velocity and density measurements at 20 C. The values of φK have been extrapolated to infinite dilution, and the total hydration numbers Zo for investigated solutions were estimated from the data φK. A correlation between the hydration and the atomic number of elements of the Period...
BACKGROUND Articular cartilage is a solid-fluid biphasic material covering the bony ends of articulating joints. Hydration of articular cartilage is important to joint lubrication and weight-wearing. The aims of this study are to measure the altered hydration behaviour of the proteoglycan-degraded articular cartilage using high-frequency ultrasound and then to investigate the effect of proteogl...
