Hydration water determines the stability and function of phospholipid membranes as well as the interaction of membranes with other molecules. Experiments and simulations have shown that water dynamics slows down dramatically as the hydration decreases, suggesting that the interfacial water that dominates the average dynamics at low hydration is slower than water away from the membrane. Here, ba...

NMR on frozen solutions is an ideal method to study fundamental questions of macromolecular hydration, because the hydration shell of many biomolecules does not freeze together with bulk solvent. In the present study, we present previously undescribed NMR methods to study the interactions of proteins with their hydration shell and the ice lattice in frozen solution. We applied these methods to ...

ABSTRACT Non-invasive bioengineering technologies continuously discovered and developed in recent decades provide a significant input to research development and remarkably contribute to the improvement of medical education and care to our patients. AIM Assessing skin hydration by using the capacitance method for a group of patients with allergic contact dermatitis versus healthy subjects, be...

Hydration of a commercial hydrophilic polyacrylamide gel in 20 meq Ca(NO 3)2/ liter was reduced to <10% of the maximum hydration in deionized water. Repeated soaking with deionized water to remove soluble salts restored hydration to ≈ 30% of maximum. Incorporating KNO3 at concentrations ranging from 5 to 40 meq·liter -1 with the Ca(NO3)2 in the hydration solution partially reversed the Ca 2+ in...

objective: aggression is a disruptive behavior that limits children’s ability for a better adjustment. as commonly reported, sleep problems is associated with the presentation of aggression in adhd children. in this study, we aimed to investigate the association between sleep problems and aggressive behavior in children with adhd.  methods: the study method is correlational and cross-sectional....

Cracks in concrete structures can serve as pathways for aggressive chemical substances that lead to a progressive deterioration of the cement stone well reinforcement, affecting load capacity, service life and useability structures. However, reinforced exhibit an intrinsic ability heal cracks, defined autogenous self-healing. This effect includes precipitation calcium carbonate presence water C...
