Phenylalanine modulates casein synthesis in bovine mammary epithelial cells by influencing amino acid transport and protein synthesis pathways

Frontiers in Nutrition
The efficiency of phenylalanine (Phe) utilization for milk protein synthesis in dairy cows is limited, and its uptake and metabolic mechanisms in the mammary tissue remaining unclear. This study investigated the effects of Phe availability (0.07, 0.14, 0.

Serum tryptophan, kynurenine, phenylalanine, tyrosine and neopterin concentrations in 100 healthy blood donors

Pteridines, 2015
Formation of neopterin, a biomarker of the activated human immune system, is linked with tryptophan (TRP) and phenylalanine (PHE) metabolism. To obtain normal values, in this study, serum concentrations of neopterin as well as of TRP, PHE and their ...

Organic Crystal Template‐Directed Fabrication of 3D Nanostructured Alumina Thin Films via Atomic Layer Deposition

Advanced Materials Interfaces, EarlyView.
This work presents a novel template‐directed approach for fabricating 3D nanostructured alumina thin films using organic crystal templates and atomic layer deposition (ALD). Free‐standing metal oxide films replicate the intricate geometries of L‐histidine and glutathione templates.

Perovskite Quantum Dots for Improvement in Efficiency of Perovskite Solar Cells: Recent Advances and Prospects

Advanced Materials Interfaces, EarlyView.
Quantum dots (QDs) boost perovskite solar cells (PSCs) performance/stability via tunable bandgap, energy alignment, and interfacial engineering. This review covers three frontiers: 1. interfacial defect passivation by Ligand‐engineered QDs in PSCs. 2. QDs multifunctional interlayers via bandgap/energy alignment. 3. QDs in tandem cells.

Polypeptide Nanotoroids Formed on Substrate via Solvent Evaporation‐Induced Self‐Assembly

Advanced Materials Interfaces, EarlyView.
Polypeptide nanotoroids are formed on substrates via a solvent evaporation‐induced self‐assembly process, which is driven by the increased interfacial energy of the initially formed polypeptide nanorods upon their exposure to air during the solvent evaporation.
