Water intake, hydration status and cognitive functions in older adults - a pilot study.
European journal of nutrition
May 9, 2025
PURPOSE: This study aimed to assess the relationship between the hydration status and cognitive functioning of older adults. The novelty of the study was the simultaneous use of several indicators of hydration status, including plasma and urine osmol...
Machine learning-based prediction of tear osmolarity for contact lens practice.
Ophthalmic & physiological optics : the journal of the British College of Ophthalmic Opticians (Optometrists)
Mar 25, 2024
PURPOSE: This study addressed the utilisation of machine learning techniques to estimate tear osmolarity, a clinically significant yet challenging parameter to measure accurately. Elevated tear osmolarity has been observed in contact lens wearers and...
Personalized prediction of optimal water intake in adult population by blended use of machine learning and clinical data.
Scientific reports
Nov 16, 2022
Growing evidence suggests that sustained concentrated urine contributes to chronic metabolic and kidney diseases. Recent results indicate that a daily urinary concentration of 500 mOsm/kg reflects optimal hydration. This study aims at providing perso...
Searching for the urine osmolality surrogate: an automated machine learning approach.
Clinical chemistry and laboratory medicine
Jul 4, 2022
OBJECTIVES: Automated machine learning (AutoML) tools can help clinical laboratory professionals to develop machine learning models. The objective of this study was to develop a novel formula for the estimation of urine osmolality using an AutoML too...
Light-driven carbon nitride microswimmers with propulsion in biological and ionic media and responsive on-demand drug delivery.
Science robotics
Jan 19, 2022
We propose two-dimensional poly(heptazine imide) (PHI) carbon nitride microparticles as light-driven microswimmers in various ionic and biological media. Their high-speed (15 to 23 micrometer per second; 9.5 ± 5.4 body lengths per second) swimming in...
Effects of a 14-Day Hydration Intervention on Individuals with Habitually Low Fluid Intake.
Annals of nutrition & metabolism
Mar 29, 2021
BACKGROUND: Debate continues over whether or not individuals with low total water intake (TWI) are in a chronic fluid deficit (i.e., low total body water) [1 ]. When women with habitually low TWI (1.6 ± 0.5 L/da...
The Influence of Fluid Intake Behavior on Cognition and Mood among College Students in Baoding, China.
Annals of nutrition & metabolism
Mar 29, 2021
INTRODUCTION: Water is a critical nutrient, and it is important for the maintenance of the physiological function of the human body [1 -3 ]. In addition to fluid amounts, f...
Dry eye is matched by increased intrasubject variability in tear osmolarity as confirmed by machine learning approach.
Archivos de la Sociedad Espanola de Oftalmologia
May 20, 2019
OBJECTIVE: Because of high variability, tear film osmolarity measures have been questioned in dry eye assessment. Understanding the origin of such variability would aid data interpretation. This study aims to evaluate osmolarity variability in a clin...
The Effects of Hydration Status on Cognitive Performances among Young Adults in Hebei, China: A Randomized Controlled Trial (RCT).
International journal of environmental research and public health
Jul 12, 2018
: Dehydration may affect cognitive performances as water accounts for 75% of brain mass. The purpose of this study is to investigate the effects of dehydration and water supplementation on cognitive performances, and to explore the changes of brain s...
Automated Planning Enables Complex Protocols on Liquid-Handling Robots.
ACS synthetic biology
Mar 5, 2018
Robotic automation in synthetic biology is especially relevant for liquid handling to facilitate complex experiments. However, research tasks that are not highly standardized are still rarely automated in practice. Two main reasons for this are the s...
