Vitamin B1 deficiency increased urinary levels of all 2-oxo acids, while vitamin B6 deficiency only increased levels of sum of 2-oxaloacetic acid and pyruvic acid, and pantothenic acid deficiency only increased levels of 2-oxoisovaleric acid. Profiles of 2-oxo acids in urine samples might be ...
However, if they are produced in excess, or if their metabolism is prevented by an inherited enzyme defect, concentrations increase in the tissues, blood and urine. Examples of excessive production are during fasting ketosis, in which acetoacetic and 3-hydroxybutyric acids and a range of ...
Results showed that CMK effectively reduced the number of unique peptide segments, generated short-chain fatty acids (SCFA) in feces, improved the content of glutamic pyruvic transaminase (GPT), glutamic oxaloacetic transaminase (GOT), amino acid, and urea nitrogen in serum, activated the contents ...

Patients were administered orally 60 ml solution (consisting of 10 g lactulose and 5 g mannitol) after evacuating the urinary bladder in the morning, and their urine was collected for the subsequent 6 h. During this period the patients were not permitted any oral intake of food or water. ...
Since gabapentin is excreted exclusively in urine without significant metabolism, the urinary recovery of gabapentin after oral dosing is equivalent to the oral bioavailability (F). This assumption requires accurate measurement of urine volumes for each collection period.Pharmacokinetic profiles of gabapentin...
This sensitivity permits precise determination of several alpha-keto acids in 5 microliter of serum or urine from healthy persons, and also the determination of phenylpyruvic acid in normal urine which cannot be simultaneously determined by other methods....
PURPOSE:To perform accurate quantitative determination of trace D-lactic acid in blood, urine, etc., in high sensitivity, by reacting a body fluid of human, etc., with a specific enzyme in the presence of NAD and reacting the obtained pyruvic acid, etc., with a fluorescent compound to ...
