An Evaluation of the Arginine Requirements of Broiler Chickens and the Potential Arginine and Energy-Saving Effects of Guanidinoacetic Acid

open access: yesAnimals
Two 35-day trials were conducted to determine the arginine (Arg) requirement of broiler chickens and the Arg and energy-sparing effects of guanidinoacetic acid (GAA). In experiment 1, a low-Arg diet (basal diet) was supplemented with increasing levels (0.

Amino acid metabolism conflicts with protein diversity [PDF]

open access: yes, 2014
The twenty protein coding amino acids are found in proteomes with different relative abundances. The most abundant amino acid, leucine, is nearly an order of magnitude more prevalent than the least abundant amino acid, cysteine.

Research Progress of Amino Acid Metabolism PET Imaging in Tumor

open access: yesJournal of Isotopes, 2015
Amino acid metabolism PET imaging plays a very important role in metabolism molecular imaging. Amino acid PET tracers include [1-11C]amino acid, labeling α-C amino acid, labeling side-chain amino acid, and N-substituted labeling amino acid.

Amino acid analysis [PDF]

open access: yes, 1974
The process and apparatus for qualitative and quantitative analysis of the amino acid content of a biological sample are presented. The sample is deposited on a cation exchange resin and then is washed with suitable solvents.

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]

open access: yes, 2015
Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

Molecular Methods for Rare Hemoglobinopathy Cases: First Brazilian Report of Pediatric Siblings with Hb O‐Arab and Alpha‐Thalassemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hemoglobinopathies are prevalent globally; diagnosis is complex in high genetic admixture populations like Brazil. We report, in two pediatric siblings, the first documented cases in Brazil of heterozygosity for hemoglobin (Hb) O‐Arab with coinheritance of α‐thalassemia (αα/−α4.2; −α3.7/−α4.2), resulting in microcytic and hypochromic anemia ...

Gut amino acid absorption in humans: Concepts and relevance for postprandial metabolism

open access: yesClinical Nutrition Open Science, 2021
Summary: Dietary amino acid absorption kinetics are an important determinant of protein quality. The term “amino acid digestibility” is commonly used to refer to the amount of ingested amino acids that become available following absorption.

The role of amino acid metabolism during abiotic stress release.

open access: yesPlant, Cell and Environment, 2019
Plant responses to abiotic stress include various modifications in amino acid metabolism. By using a hydroponic culture system, we systematically investigate modification in amino acid profiles and the proteome of Arabidopsis thaliana leaves during ...

Alterations in serum amino acid concentrations in dogs with protein-losing enteropathy [PDF]

open access: yes, 2018
BackgroundCertain amino acids are decreased in humans with inflammatory bowel disease (IBD) and supplementation with the same amino acids has shown beneficial effects in animal models of IBD.

Upacicalcet: A Novel Intravenous Calcimimetic Agent for Patients Undergoing Hemodialysis With Secondary Hyperparathyroidism

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.
