Hepatic fibrogenesis requires sympathetic neurotransmitters [PDF]

open access: yes, 2004
Background and aims: Hepatic stellate cells (HSC) are activated by liver injury to become proliferative fibrogenic myofibroblasts. This process may be regulated by the sympathetic nervous system (SNS) but the mechanisms involved are unclear.

Altered Dopamine Metabolism and Response to Treatment with Levodopa/Carbidopa in MCT8 Deficiency

open access: yesMovement Disorders, EarlyView.
Abstract Background Allan‐Herndon‐Dudley syndrome (AHDS)/monocarboxylate transporter 8 (MCT8) deficiency is a rare X‐linked encephalopathy caused by SLC16A2 variants, impairing thyroid hormone (TH) transport into the brain. This leads to early central nervous system (CNS) TH deficiency, affecting brain maturation.

Smoking-induced long-lasting modifications of human platelet serotonin catabolism through a MAO epigenetic regulation [PDF]

open access: yes, 2008
Postulating that serotonin, secreted from smoking-activated platelets, could be involved in smoking-induced vascular modifications, we studied 115 men distributed in smokers (S), former smokers (FS) and never smokers (NS).

Individual differences in impulsive and risky choice: effects of environmental rearing conditions [PDF]

open access: yes, 2014
The present experiment investigated early-rearing environment modulation of individual differences in impulsive and risky choice. Rats were reared in an isolated condition (IC; n = 12), in which they lived alone without novel stimuli, or an enriched ...

Effect of Social Rank on Gut Microbes and Their Metabolites of Greater Long‐Tailed Hamsters (Tscherskia triton)

open access: yesIntegrative Zoology, EarlyView.
Social rank in greater long‐tailed hamsters (Tscherskia triton) shapes gut microbiota composition and metabolite profiles. Dominant males exhibit a “high‐vigilance, metabolically activated” phenotype, with elevated aggression and specific gut microbiota enriched in energy‐harvesting taxa and fecal queuine.

A Comparative Study on Neurochemistry of Cerebrospinal Fluid in Advanced Parkinson's Disease

open access: yesNeurobiology of Disease, 1999
This study addresses two issues: (1) the comparative neurochemistry of classic tremor type of Parkinson's disease or PD-A and akinetic type of Parkinson's disease or PD-B; and (2) the neurochemistry of levodopa failure syndrome (LDFS).

Tryptophan metabolite atlas uncovers organ, age, and sex‐specific variations

open access: yesFEBS Open Bio, Volume 16, Issue 1, Page 52-67, January 2026.
Tryptophan metabolites were analyzed across twelve organs, the central nervous system, and serum in male and female mice at three life stages. We found tissue‐, sex‐, and age‐specific differences, including increased indole‐3‐pyruvate and kynurenine in aging males.

Neuropeptide Y and Calcitonin Gene-Related Peptide in Cerebrospinal Fluid in Parkinson’s Disease with Comorbid Depression versus Patients with Major Depressive Disorder

open access: yesFrontiers in Psychiatry, 2017
Parkinson’s disease (PD) is the second most common neurodegenerative disease in the world. The diagnosis of PD is based on movement dysfunctions. Many patients also suffer from comorbid depression in spite of adequate treatment with dopamine replacement,
