2002年9月30日 · The present study investigated whether thermal sweating may relieve elevated concentrations of serum uric acid or urea. Concentrations of uric acid and urea were measured in the sweat of sixteen male volunteers, who were treated with external heat after one hour of intense physical exercise.

2021年7月16日 · In humans, urea is excreted in sweat, largely through the eccrine sweat gland. The urea concentration in human sweat is elevated when compared to blood urea nitrogen. The sweat urea nitrogen (UN) of patients with end‐stage kidney disease (ESRD) is increased when compared with healthy humans.

For example, sweat contains urea, the major nitrogen-containing metabolic product of protein catabolism. According to Sato , urea readily crosses the eccrine glandular wall and

An analysis revealed higher excretion levels of urea, Na +, and K + during running than in inactive overheating and in the apocrine than in the eccrine sweat glands. Urea is generally regarded as one of the primary metabolic products evident in human perspiration (along with other chemical compositions, such as ammonia, lactic acid, or heavy ...

In humans, urea is excreted in sweat, largely through the eccrine sweat gland. The urea concentration in human sweat is elevated when compared to blood urea nitrogen. The sweat urea nitrogen (UN) of patients with end‐stage kidney disease (ESRD) is increased when compared with healthy humans.

Urea concentration in the sweat fluid was found to be present at a much higher concentration than the serum level (reaching in some cases 50 times the serum level). The possibility of using thermal induction as an alternative to haemodialysis is suggested.

2024年1月24日 · The results illustrate a proof of principle of urea measurements in sweat and saliva to monitor HD adequacy in a non-invasive and continuous manner. Biosensors enabling urea monitoring in sweat or saliva could fill in a clinical need to enable at-home HD for more patients and thereby decrease patien …

2023年3月1日 · Herein, we introduce wearable potentiometric biosensors on screen-printed carbon electrodes (SPCEs) for on-body and on-site monitoring of urea in sweat. The biosensor architecture was judiciously designed to detect urea at different pHs and incorporate a pH sensor, thus containing polyaniline ink, urease bioink and a polyvinylchloride membrane.

2024年11月21日 · Key components in sweat, such as urea and glucose, are closely linked to kidney function and blood glucose levels. Portable sweat sensors, equipped with diverse sensing systems, can monitor fluctuations in urea and glucose concentrations, thus providing methods for assessing kidney function and monitoring diabetes.

The presence of urea in the sweat fluid at such a high level suggests a selective transport mechanism across the eccrine sweat gland to clear the blood of a high urea level. Concentrations of creatinine, uric acid and urea were measured in the blood and urine of female patients at the final stage of renal disease and on a regul
