In this study, AuPdCu-rGO-MWCNTs nanocomposite was synthesised by a chemical reduction method which was applied to fabricate an electrochemical sensor for simultaneous determination Dopamine (DA), Acetaminophen (AC) and Tryptophan (Trp) by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. The formation of Au, Pd, and Cu nanoparticles on rGO-MWCNTs nanocomposite are ch...

Background: It has been shown that a possible pathogenetic mechanism of neurodegeneration in the mouse model glaucoma (DBA/2J) may be an alteration kynurenic acid (KYNA) retina. This study aimed to verify hypothesis alterations tryptophan (TRP) metabolism DBA/2J mice is not limited Methods: Samples retinal tissue and serum were collected from (6 10 months old) control C57Bl/6 same age. The conc...

this experiment was conducted to evaluate the effects of turmeric powder (trp), tomato pomace (tp), fat sources (canola oil, soybean oil and tallow) on immune system and jejunum morphometric parameters of heat stressed broiler chickens. five hundred four one-d-old ross broiler were randomly distributed to 36 experimental units and 12 dietary treatments (3 replicates with 12 birds in each). the ...

in the present work, an efficient modified carbon-ceramic electrode by multi-walled carbon nanotubes/ionic liquid nanocomposite (mwcnts/il/cce) was prepared through a simple and repeatable procedure. the introduced modified electrode was used for the study of the electrochemical behaviour and determination of tryptophan (trp) in the presence of uric acid (ua) using cyclic voltammetry (cv), diff...

Tryptophan (Trp) is an essential amino acid that can be metabolized via endogenous and exogenous pathways, including the Kynurenine Pathway, 5-Hydroxyindole Pathway (also Serotonin pathway), Microbial pathway. Of these, Trp metabolic pathways in gut have recently been extensively studied for their production of bioactive molecules. The microbiota plays important role host metabolism immunity, m...

Fermentation is a traditional technique used to increase nutrients, flavonoids, vitamins, minerals, and the flavor of raw materials. In this study, adlay bran was fermented by Lactobacillus brevis MJM60390 (FAB), anti-melanogenic effect investigated. The results demonstrated that FAB significantly suppressed melanin accumulation in mouse melanogenic B16F10 cells, activity higher than non-fermen...

L-Tryptophan (L-Trp) is of great importance in the biochemical, pharmaceutical and dietetic fields as it is precursor molecule of some hormones, neurotransmitters and other relevant biomolecules. So, determination of this amino acid has important role in detection of some neuron based disease. The main purpose of this report was to develop application of Fe3O4 magnetic nanoparticles/graphene qu...

Tryptophan (Trp) is an essential amino acid, commercially available as a feed-grade product, and precursor to serotonin melatonin, which are both important molecules in stress mitigation. Meagre have high potential for marine aquaculture diversification but highly susceptible stressful conditions. This study aimed assess the role of dietary tryptophan supplementation meagre juveniles order mini...
