Dehydration is a frequent etiology of morbidity and mortality in elderly people. It causes the hospitalization of many patients and its outcome may be fatal. Indeed, dehydration is often linked to infection, and if it is overlooked, mortality may be over 50%. Older individuals have been shown to have a higher risk of developing dehydration than younger adults. Modifications in water metabolism ...

The vasopressin-aquaporin 2 system plays a key role in urine concentration in dehydration. In contrast to the upregulation of aquaporin 2, the downregulation of the vasopressin V2 receptor in dehydration is known. We investigated the mechanisms of this downregulation in dehydration using reverse transcription-competitive polymerase chain reaction (RT-competitive PCR) and Western blot analysis. ...

Abiotic stresses have negative effects on potato growth and production. To enhance the abiotic stress tolerance of the commercial potato cultivar, Desiree, rd29A::AtDREB1A transgenic lines have been developed. The salinity and freeze tolerance of these transgenic lines has previously been demonstrated; however, their dehydration tolerance remains to be elucidated. First of all, we have tackled ...

CHURCHILL, T.A., and STOREY, K.B. 1994. Metabolic responses to dehydration by liver of the wood frog, Rana sylvatica. Can. J. Zool. 72: 14201425. The metabolic responses by the liver to the evaporative loss of up to 60% of total body water were quantified in spring-collected wood frogs, Rana sylvatic*~, a freeze-tolerant species. Dehydration stimulated rapid hyperglycemia, liver glucose levels ...

Resurrection plants can tolerate extreme water loss. Substantial sugar accumulation is a phenomenon in resurrection plants during dehydration. Sugars have been identified as one important factor contributing to desiccation tolerance. Phylogenetic diversity of resurrection plants reflects the diversity of sugar metabolism in response to dehydration. Sugars, which accumulate during dehydration, h...

Background: Methanol is regarded as a biorenewable platform feedstock because nearly all bioresources can be converted into methanol through syngas. Biological conversion of methanol using synthetic methylotrophs has thus gained worldwide attention. Results: Herein, to endow Escherichia coli with the ability to utilize methanol, an artificial linear methanol assimilation pathway was assembled i...

OBJECTIVE To investigate the effect of dehydration time on tooth colour measurement in vitro using colourimetry. METHODS Ten extracted human maxillary central incisors were used. L*a*b* values at the centre of the labial surface of each tooth were measured using a colourimeter. The first measurement was performed after removal of excess water. The second and third measurements were performed ...

To identify the factors related to dehydration from diarrhoea, a hospital-based case-control study was carried out among under-2-year-old Bangladeshi children. The study compared 80 cases who had 'some' or severe dehydration with 160 age-matched controls who had 'no signs' of dehydration. All the cases and controls were examined and the mothers were interviewed in the hospital and followed at h...

BACKGROUND/OBJECTIVE Fluid, electrolytes and acid base disturbances are responsible for most deaths due to acute diarrhoea. The aim of this study is to describe the point-of-admission serum electrolyte profile of children with dehydration due to acute diarrhoea. METHODS In this cross-sectional study, the serum electrolyte levels of 185 children with dehydration due to acute diarrhoea were ass...
