This study explored the effects of physical activity (PA) and ambient temperature on water turnover and hydration status. Five-hundred seventy three healthy men and women (aged 20-60 years) from Spain, Greece and Germany self-reported PA, registered all food and beverage intake, and collected 24-h urine during seven consecutive days. Fasting blood samples were collected at the onset and end of ...

Purpose The purpose of this study was to characterize the relation between corneal hydration and stiffening effects of the UVA/riboflavin collagen crosslinking treatment and to investigate how artificially swelling the cornea prior to this treatment procedure affects tensile property improvement. Methods Porcine corneas were collagen crosslinked in vitro at different hydration levels using a ...

A great health concern in many countries is the rising progression of overweight and obesity in societies undergoing nutritional and epidemiological transitions. Overweight and obesity has become a global pandemic that has major health and economic consequences. The global transition in food consumption and in physical activity habits probably plays an important role as discussed by various aut...

Alkali-free, aluminium-based accelerators are often used for shotcrete linings in tunnels and mines, where external sulfate attack can occur. Therefore, it is essential to know, if the influence of on cement hydrate assemblage negatively impacts resistance. This study focuses effect hydration consequences attack. Aluminum sulfate-based cause rapid setting due very early formation ettringite acc...

In order to develop a simple and effective activation method of low calcium fly ash concrete (FAC) and to understand their basic properties, the present paper experimentally investigates the influences of the volume of fly ash (FA), the dosage of the activator (AC) and the water to binder ratio (w/b) on the hydration, setting times and the crack-resistance properties of activated FACs. Results ...

We have investigated Ca(2+)-involving cell signaling, plasma membrane potentials and conductances and callose formation during early stages of pollination of papillae of Brassica napus. Using fluorescence imaging of calcium green-1, we found that application of a range of pollen types and controls all rapidly produced small localized peaks in papillar cytoplasmic [Ca2+]. This response was more ...

calcium aluminates (ca) are the most important hydraulically setting cements used for preparing refractory castables, because they develop high strength at very early ages after placements.  the anhydrous phases of this kind of cements are ca, ca2 and traces of c12a7 and alpha-alumina. the major hydraulic phase in all of the ca cements including ciment fondue is ca. once hydrated, it starts to ...

the current methods for treatment of cancers are inadequate and more specific methods such as gene therapy are in progress. among different vehicles, cationic liposomes are frequently used for delivery of genetic material. this investigation aims to prepare and optimize dotap cationic liposomes containing an antisense oligonuclotide (asodn) against protein kinase c alpha in non-small cells lung...
