From Salt‐Affected Marginal Land Resource to Remediation Agent: Halophyte‐Derived Biochar for Ameliorating Cd‐Contaminated Acidic Soil

Land Degradation &Development, EarlyView.
ABSTRACT Cadmium (Cd) contamination of acidic soils poses a significant threat to ecosystem stability and crop health. This study evaluated the potential of biochar derived from the halophyte Salicornia europaea (SBC), a salt‐tolerant plant that grows on saline‐alkali marginal land, to remediate Cd‐contaminated acidic soil.

Predator stress-induced depression is associated with inhibition of hippocampal neurogenesis in adult male mice

Neural Regeneration Research, 2019
Stress has been suggested to disturb the 5-hydroxytryptamine system and decrease neurogenesis, which contribute to the development of depression. Few studies have investigated the effect of predator stress, a type of psychological stress, on depression ...

Altered Cerebrospinal Fluid Tryptophan–Kynurenine Pathway Metabolism in Multiple System Atrophy

Movement Disorders, EarlyView.
Abstract Background Alterations in tryptophan–kynurenine (TRP‐KYN) metabolism, which is associated with neuroinflammation, remain unclear in multiple system atrophy (MSA). Objective The aim was to investigate cerebrospinal fluid (CSF) TRP metabolites in MSA and their associations with other biomarkers.

COVID‐19 Amplifies Sex‐Specific Dopamine and Glial Responses in a Parkinson's Disease Mouse Model

Movement Disorders, EarlyView.
Abstract Background Exposure to environmental agents, including viral infections, may increase Parkinson's disease (PD) susceptibility, especially in males, but the neurodegenerative risk extent of COVID‐19 remains uncertain. Objectives We investigated the plausible link between severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection and

Increase of Urinary 5-Hydroxyindoleacetic Acid Excretion but Not Serum Chromogranin a Following Over-The-Counter 5-Hydroxytryptophan Intake

Canadian Journal of Gastroenterology, 2008
BACKGROUND: 5-hydroxyindoleacetic acid (5-HIAA) excretion is commonly measured for biochemical detection of carcinoid tumours. A 77-year-old woman was referred for elevated 24 h urine 5-HIAA excretion (510 μmol/day; normal is less than 45 μmol/day) and ...
