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 concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scientists have demonstrated a way to wa...

Water forms spine of hydration around DNA group finds
2017/7/20
Water is the Earth’s most abundant natural resource, but it’s also something of a mystery due to its unique solvation characteristics – that is, how things dissolve in it.“It’s uniquely adapted to bio...
Researchers Develop Wearable,Low-Cost Sensor to Measure Skin Hydration
Researchers Wearable Low-Cost Sensor Measure Skin Hydration
2017/2/16
A wearable skin hydration sensor in the form of a capacitor is demonstrated based on skin impedance measurement. The capacitor consists of two interdigitated or parallel electrodes that are made of si...
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...
