The paradoxes hidden behind the Droop model highlighted by a metabolic approach

Frontiers in Plant Science, 2022
We propose metabolic models for the haptophyte microalgae Tisochrysis lutea with different possible organic carbon excretion mechanisms. These models—based on the DRUM (Dynamic Reduction of Unbalanced Metabolism) methodology—are calibrated with an ...

Nitrogen Intake and Its Partition on Urine, Dung and Products of Dairy and Beef Cattle in Chile

Agronomy, 2021
Nitrogen that is excreted through the urine and dung of cattle is an important source of nitrous oxide and ammonia emissions. In Chile, several studies have evaluated nitrogen (N) intake and its partitioning into urine and dung from beef and dairy cattle,

Feasibility of achieving different protein targets using a hypocaloric high-protein enteral formula in critically ill patients

Critical Care, 2021
Background and aims Combining energy and protein targets during the acute phase of critical illness is challenging. Energy should be provided progressively to reach targets while avoiding overfeeding and ensuring sufficient protein provision.

Comparative Effect of Cecal Ligation and Colostomy on Nitrogen Utilization in Chickens Fed Low Protein or Urea-Supplemented Low Protein Diets.

The Journal of Poultry Science, 2003
A study was carried out to investigate nitrogen metabolism in response to cecal ligation and colostomy in chickens. We used colostomized plus ceca-ligated chickens fed a low protein diet or a low protein diet supplemented with urea.

Urinary felinine excretion in intact male cats is increased by dietary cystine [PDF]

, 2008
Felinine is a branched-chain sulfur amino acid present in the urine of certain Felidae, including domestic cats. The objective of the present study was to determine if additional cystine and/or dietary N would increase felinine and N-acetylfelinine ...

The role of energy, serine, glycine, and 1-carbon units in the cost of nitrogen excretion in mammals and birds

Animal, 2021
The efficiency with which dietary protein is used affects the nitrogen excretion by the animal and the environmental impact of animal production. Urea and uric acid are the main nitrogen excretion products resulting from amino acid catabolism in mammals ...
