LARP6C orchestrates posttranscriptional reprogramming of gene expression during hydration to promote pollen tube guidance
LARP6C gene expression posttranscriptional regulation pollination fertilization
2023/12/1
Increasing evidence suggests that posttranscriptional regulation is a key player in the transition between mature pollen and the progamic phase (from pollination to fertilization). Nonetheless, the ac...
The void in using urine concentration to assess population fluid intake adequacy or hydration status
dehydration fluid needs hydration assessment hypohydration hypovolemia
2018/12/13
Urine concentration can be used to assess fluid intake adequacy or to diagnose dehydration. However, too often urine concentration is used inappropriately to draw dubious conclusions that could have h...
Urinalysis for hydration assessment: an age-old problem
hydration assessment age-old problem
2018/11/30
Urinalysis has provided a noninvasive means of assessing human health for thousands of years. The daily volume of urine has been a proxy for water needs since the time of Galen of Pergamon (AD 129–200...
Four-component model of body composition in children: density and hydration of fat-free mass and comparison with simpler models
Body fat dual-energy X-ray absorptiometry total body water
2016/5/31
Body composition in children is generally measured
by 2-component (2C) models, which are subject to error
arising from variation in fat-free mass (FFM) composition. The
4-component (4C) model, whic...
Hydration of fat-free body mass: review and critique of a classic body-composition constant
body composition mammals dual-energy X-ray absorptiometry
2016/5/31
The assumed “constancy” of fat-free body
mass hydration is a cornerstone in the body-composition
research field. Hydration, the observed ratio of total body water
to fat-free body mass, is stable a...

2016/5/25
The role of electric fields in important biological processes such as binding and catalysis has been studied almost exclusively by computational methods. Experimental measurements of the local electri...
The impact of post-exercise hydration with deep-ocean mineral water on rehydration and exercise performance
Hydration Deep-ocean mineral water Peak torque extension
2016/5/16
Background:Dehydration caused by prolonged exercise impairs thermoregulation, endurance and exercise performance. Evidence from animal and human studies validates the potential of desalinated deep-oce...
