The digital epidemiology of phenylketonuria, aka folling’s disease: retrospective analysis and geographic mapping via google trends

open access: yesAsian Journal of Medical Sciences, 2018
Background: Phenylketonuria, commonly known as PKU, is an inherited disorder in which there is an abnormally elevated blood level of the amino acid phenylalanine leading to several pathologies affecting multiple organs including the central nervous ...

Molecular Dynamics Simulation Study of the Self-Assembly of Phenylalanine Peptide Nanotubes

open access: yesNanomaterials, 2022
In this paper, we propose and use a new approach for a relatively simple technique for conducting MD simulation (MDS) of various molecular nanostructures, determining the trajectory of the MD run and forming the final structure using external force ...

Potential uptake of dissolved organic matter by seagrasses and macroalgae [PDF]

open access: yes, 2011
Dissolved organic nitrogen (DON) acts as a large reservoir of fixed nitrogen. Whereas DON utilization is common in the microbial community, little is known about utilization by macrophytes.

Calibration-free measurement of phenylalanine levels in blood using an electrochemical aptamer-based sensor suitable for point-of-care applications.

open access: yesACS Sensors, 2019
By analogy to the revolution the "home glucose monitor" created in the treatment of diabetes, the availability of a modular, "platform" technology able to measure nearly any metabolite, biomarker or drug "at-home" in unprocessed, finger-prick volumes of ...

Phenylalanine hydroxylase activity and expression in chicks subjected to phenylalanine imbalance or phenylalanine toxicity

open access: yesPoultry Science, 2009
Experiments were performed to investigate the activity of hepatic Phe hydroxylase (PAH) and plasma amino acid concentrations under conditions of Phe imbalance or toxicity in chicks fed on experimental diets from 7 to 14 or 16 d of age. In experiment 1, Phe imbalance was created by adding 10% of a mixture of indispensable amino acids lacking Phe (IAA ...

Outstanding chain-extension effect and high UV resistance of polybutylene succinate containing amino-acid-modified layered double hydroxides

open access: yesBeilstein Journal of Nanotechnology, 2019
Polybutylene succinate (PBS) nanocomposite materials were prepared using a melt compounding process. The Mg2Al-based PBS nanocomposites, dispersed with inorganic–organic hybrid materials (layered double hydroxides, LDHs), were functionalized with the ...

Phenylalanine Monitoring via Aptamer-Field-Effect Transistor Sensors.

open access: yesACS Sensors, 2019
Determination of the amino acid phenylalanine is important for lifelong disease management in patients with phenylketonuria, a genetic disorder in which phenylalanine accumulates and persists at levels that alter brain development and cause permanent ...

Role of Phenylalanine and Its Metabolites in Health and Neurological Disorders

open access: yes, 2020
Phenylalanine, an amino acid, is a “building block” of protein. Phenylalanine is a component of food sources and also derived through supplementation. In current treatment, phenylalanine is prescribed as anti-depressant agent.
