The kynurenine and serotonin pathway, neopterin and biopterin in depressed children and adolescents: an impact of omega-3 fatty acids, and association with markers related to depressive disorder. A randomized, blinded, prospective study

Frontiers in Psychiatry
Depressive disorder is a severe mental condition. In addition to genetic factors, immunological-inflammatory factors, oxidative stress, and disturbances in neurotransmitter metabolism, kynurenine and serotonin pathways may play a role.

Specific Urinary Metabolites in Malignant Melanoma

Medicina, 2019
Background and objectives: Melanin, which has a confirmed role in melanoma cell behaviour, is formed in the process of melanogenesis and is synthesized from tryptophan, L-tyrosine and their metabolites.

Metarhizium anisopliaeMitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

Advanced Science, EarlyView.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design

Advanced Science, EarlyView.
Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...

Establishment of a mouse model of TMAO‐induced cardiac injury and application of MICT intervention

Animal Models and Experimental Medicine, EarlyView.
This study aims to explore the establishment of an animal model of cardiac injury induced by trimethylamine‐N‐oxide (TMAO), a metabolite secreted by gut microorganisms, and to investigate its application in moderate‐intensity continuous training (MICT) intervention.

Associations of gut microbiota features and circulating metabolites with systemic inflammation in children

BMJ Open Gastroenterology
Objective Gut microbes and microbe-dependent metabolites (eg, tryptophan-kynurenine-serotonin pathway metabolites) have been linked to systemic inflammation, but the microbiota-metabolite-inflammation axis remains uncharacterised in children.

The Kynurenine Pathway: a Proposed Mechanism Linking Diabetes and Periodontal Disease in Diabetic Patients

Dental Hypotheses, 2011
Introduction: Diabetes mellitus is a metabolic disease characte-rized by dysregulation of carbohydrate, protein and lipid metabolism. Diabetes could result, in part, in activation of tryptophan metabolism.

Relationships between brain activity, tryptophan-related gut metabolites, and autism symptomatology

Nature Communications
While it has been suggested that alterations in the composition of gut microbial metabolites may play a causative role in the pathophysiology of autism spectrum disorder (ASD), it is not known how gut microbial metabolites are associated with ASD ...

Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

Applications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.
