The kynurenine pathway as a therapeutic target in cognitive and neurodegenerative disorders [PDF]

open access: yes, 2013
Understanding the neurochemical basis for cognitive function is one of the major goals of neuroscience, with a potential impact on the diagnosis, prevention and treatment of a range of psychiatric and neurological disorders.

Phenylalanine and Tryptophan Intake of Hyperactive Children with Autism

open access: yesJournal of Biomedicine and Translational Research, 2017
Background: Hyperactive is behavior which demonstrates the attitude of more energy than normal behavior. Level of neurotransmitter dopamine and serotonin in the body may be the factor of this disorder behavior.

Tryptophan Metabolism in Alcoholism [PDF]

open access: yesNutrition Research Reviews, 1999
Studies of tryptophan (Trp) metabolism in relation to the serotonin status in alcoholism are of 2 types: (1) those related to the pharmacological effects of ethanol; (2) those concerning the serotonin status in the absence of alcohol intake. In experimental animals, acute and chronic ethanol administration and subsequent withdrawal exert a variety of ...

Ultraviolet Photostability Improvement for Autofluorescence Correlation Spectroscopy on Label-Free Proteins [PDF]

open access: yesarXiv, 2020
The poor photostability and low brightness of protein autofluorescence have been major limitations preventing the detection of label-free proteins at the single molecule level. Overcoming these issues, we report here a strategy to promote the photostability of proteins and use their natural tryptophan autofluorescence in the ultraviolet (UV) for ...

Nicotinic α7 acetylcholine receptor-mediated currents are not modulated by the tryptophan metabolite kynurenic acid in adult hippocampal interneurons [PDF]

open access: yes, 2012
The tryptophan metabolite, kynurenic acid (KYNA), is classically known to be an antagonist of ionotropic glutamate receptors. Within the last decade several reports have been published suggesting that KYNA also blocks nicotinic acetylcholine receptors (nAChRs) containing the \alpha7 subunit (\alpha7*).

The therapeutic potential of targeting tryptophan catabolism in cancer

open access: yesBritish Journal of Cancer, 2019
Based on its effects on both tumour cell intrinsic malignant properties as well as anti-tumour immune responses, tryptophan catabolism has emerged as an important metabolic regulator of cancer progression. Three enzymes, indoleamine-2,3-dioxygenase 1 and

The Use of Dietary Additives in Fish Stress Mitigation: Comparative Endocrine and Physiological Responses [PDF]

open access: yes, 2019
In the last years, studies on stress attenuation in fish have progressively grown. This is mainly due to the interest of institutions, producers, aquarists and consumers in improving the welfare of farmed fish.

L-Tryptophan Enhances Intestinal Integrity in Diquat-Challenged Piglets Associated with Improvement of Redox Status and Mitochondrial Function

open access: yesAnimals, 2019
Tryptophan (Trp) supplementation has been shown to improve growth performance and enhance intestinal integrity in piglets. However, the effects of dietary Trp supplementation on the intestinal barrier function in piglets exposed to oxidative stress ...

Is Amino-Acid Homochirality Due To Asymmetric Photolysis In Space? [PDF]

open access: yesarXiv, 1999
Amino acids occurring in proteins are, with rare exceptions, exclusively of the L-configuration. Among the many scenarios put forward to explain the origin of this chiral homogeneity (i.e., homochirality), one involves the asymmetric photolysis of amino acids present in space, triggered by circularly polarized UV radiation.
