Dehydration (body water deficit) is a physiologic state that can have profound implications for human health and performance. Unfortunately, dehydration can be difficult to assess, and there is no single, universal gold standard for decision making. In this article, we review the physiologic basis for understanding quantitative dehydration assessment. We highlight how phenomenologic interpretat...

Pervaporation (PV) is a well-established membrane technique used in separation; especially dehydration of organic solvents. Along with other parameters such as permeate pressure and feed temperature; feed composition is an important parameter, which affects separation characteristics and membrane performance in pervaporation. In this paper, the separation characteristics of a hydrophilic polyvi...

due to poor solubility in lipids, many of bioactive components (nutraceutical materials) show less bioactivity than optimal state in water solution. phytosomes improve absorption and bioavailability of biomaterials. liposomes, spherical shaped nanocarriers, were discovered in the 1960s by bangham. due to their composition, variability and structural properties, liposomes and phytosomes are extr...

conclusions it is reasonable to evaluate blood urea nitrogen, potassium, and hemoglobin of children with gastroenteritis. moreover, conducting white blood cell, stool exam, and urine analysis is recommended for those with febrile gastroenteritis, especially in girls younger than two years of age. overall, conducting all the mentioned tests for these patients is not necessary as a routine, and d...

OBJECTIVE The fluid recommendation for adults aged 70+ years has been criticised on the basis of a low prevalence of dehydration in community-dwelling older adults. This study explores whether the low prevalence might reflect limitations of individual dehydration indices. DESIGN Cross-sectional data on plasma sodium, blood urea nitrogen (BUN), creatinine, glucose and potassium were used to cl...

Limited information is available regarding the effects of mild dehydration on cognitive function. Therefore, mild dehydration was produced by intermittent moderate exercise without hyperthermia and its effects on cognitive function of women were investigated. Twenty-five females (age 23.0 ± 0.6 y) participated in three 8-h, placebo-controlled experiments involving a different hydration state ea...

Aluminosilicate gel precursor having mullite composition was synthesized from inorganic salts of aluminum and silicon by employing the sol-gel method. Chemical analysis, surface area and bulk density measurements were performed to characterize the dried gel. The course of the mullitization was examined by FT-IR analysis which confirmed the diphasic nature of the gel. ...
