Background Switchgrass (Panicum virgatum L.) is a model biofuel plant because of its high biomass, cellulose-richness, easy degradation to ethanol, and the availability of extensive genomic information. However, a little is currently known about the molecular responses of switchgrass plants to dehydration stress, especially multiple dehydration stresses. Results Studies on the transcriptional...

Abstract Background and Aims Renal frailty (RF) is a premorbid and, at least partly, modifiable condition arising from diminished renal functional reserve defective adaptive response capacity predisposing to acute kidney injury (AKI). RF ensues subclinical wear or distortion of the haemodynamic tubular homeostatic responses that defend excretory function supervening circumstances (i.e., stresso...

Physcomitrella patens is an extremely dehydration-tolerant moss. However, the molecular basis of its responses to loss of cellular water remains unclear. A comprehensive proteomic analysis of dehydration- and rehydration-responsive proteins has been conducted using quantitative two-dimensional difference in-gel electrophoresis (2D-DIGE), and traditional 2-D gel electrophoresis (2-DE) combined w...

Ticks are obligate blood feeders but spend the majority of their lifetime off-host where they must contend with a multitude of environmental stresses. Survival under desiccating conditions is a determinant for habitats where ticks can become established, and water-balance characteristics of ticks have been extensively studied. However, little is known about the underlying aspects associated wit...

Aloe vera gel is widely used as a functional ingredient in food processing. This gel is very unstable due to its high water activity. Drying process can be used to obtain shelf stable products. Response surface methodology was used to assess the effects of solution concentration (30-60% w/w), solution temperature (30-50°C) and immersion time (4-6h) at atmospheric pressure and constant solution ...

BACKGROUND Acute gastroenteritis is characterized by diarrhea, which may be accompanied by nausea, vomiting, fever, and abdominal pain. OBJECTIVE To review the evidence on the assessment of dehydration, methods of rehydration, and the utility of antiemetics in the child presenting with acute gastroenteritis. DISCUSSION The evidence suggests that the three most useful predictors of 5% or mor...

Salter-Venzon D, Watts AG. The role of hypothalamic ingestive behavior controllers in generating dehydration anorexia: a Fos mapping study. Am J Physiol Regul Integr Comp Physiol 295: R1009–R1019, 2008. First published July 30, 2008; doi:10.1152/ajpregu.90425.2008.— Giving rats 2.5% saline to drink for 3–5 days simply and reliably generates anorexia. Despite having the neurochemical and hormona...
