Guar gum does not impair the absorption and utilization of dietary nitrogen but affects early endogenous urea kinetics in humans
Guar gum dietary nitrogen urea kinetics
2016/6/14
Viscous gums enhance viscosity in the upper gastrointestinal
lumen, quickly disturbing motility and promoting
fluid secretion.
Effect of acute zinc depletion on zinc homeostasis and plasma zinc kinetics in men
rate constants plasma zinc zinc homeostasis

Amino acid kinetics in patients with sepsis
Sepsis hypermetabolism plasma amino acids amino acid elimination
2016/6/13
In patients with sepsis and systemic inflammatory
response syndrome, amino acid extraction by the liver is
enhanced, resulting in decreased plasma amino acid concentrations.

De novo lipogenesis, lipid kinetics, and whole-body lipid balances in humans after acute alcohol consumption
lipolysis hypertriglyceridemia acetate
2016/6/2
Acute alcohol intake is associated with changes in
plasma lipid concentrations and whole-body lipid balances in
humans. The quantitative roles of hepatic de novo lipogenesis
(DNL) and plasma acetat...

Leptin is known to be cleared by the kidney, a tissue
with substantial leptin receptor mRNA expression; however,
lung, liver, and muscle tissues also express leptin receptor messenger
RNA and it is...
The gut takes nearly all：threonine kinetics in infants1,2,3
Threonine preterm infants intestine stable isotopes nutrition

Background:Threonine is an essential amino acid that is abundantly present in intestinally produced glycoproteins. Animal studies show that intestinal first-pass threonine metabolism is high, partic...
Calculation of red blood cell folate steady state conditions and elimination kinetics after daily supplementation with various folate forms and doses in women of childbearing age
Red blood cell folate steady state elimination kinetics neural tube defects
2008/12/22
Background: A maternal red blood cell (RBC) folate concentration > 906 nmol/L is thought to be optimal for lowering the risk of neural tube defects (NTDs) in pregnancy. Whereas the appearance of f...
Long-term effects of perinatal nutrition on T lymphocyte kinetics in young Gambian men1,2,3
Nutritional programming T cell kinetics lymphocytes Gambia stable isotopes

The deuterated-retinol-dilution technique provides a quantitative estimate of total-body vitamin A (TBVA) stores in adults. To apply the technique to children, information on plasma retinol kinetics i...
Effect of sex and obesity on basal VLDL-triacylglycerol kinetics
lipolysis VLDL-triacylglycerol kinetics
2016/12/29
Plasma fatty acid availability is a major regulator of VLDL-triacylglycerol production. Basal whole-body lipolysis is higher in women than in men and is higher in persons with abdominal obesity than i...

docosahexaenoic acid compartmental model isotope tracer
2016/12/29
The quantity and type of dietary polyunsaturated fatty acids (PUFAs) can alter essential fatty acid metabolism in humans. Diets rich in 20- and 22-carbon PUFAs may inhibit desaturase expression or act...
