INTRODUCTION Diarrhea remains one of the most common and most deadly conditions affecting children worldwide. Accurately assessing dehydration status is critical to determining treatment course, yet no clinical diagnostic models for dehydration have been empirically derived and validated for use in resource-limited settings. METHODS In the Dehydration: Assessing Kids Accurately (DHAKA) prospe...

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...

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...

Solid phase microextraction and gas chromatography-mass spectrometry (SPME-GC-MS) are commonly used for qualitative and quantitative analysis of volatile compounds in various dairy products, but conditions have to be adjusted to maximize release while not generating new compounds that are absent in the original sample. Queso Fresco, a fresh non-melting cheese, may be heated at 60 °C for 30 min;...

The experimentally investigation for dehydration of gas streams in a fixed-bed adsorption column using 4A molecular sieve was reported the first time. Different operating conditions system were performed, such as flow rate (2.0, 5.0 and 8.0 L min.-1) bed depths (10, 20 30 cm). A significantly decreased (p ≤ 0.05) exhaustion time verified result increase rate. On other hand, rupture mass transfe...

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...
