Variation in the ginsenoside content of American ginseng, Panax quinquefolius L., roots
The weights and ginsenoside levels of twenty 4-year-old American ginseng (Panax quinquefolius) roots harvested from a homogeneous-looking 1-m2 plot were determined. It was found that the dry weightExpand

Oxidative-stress associated parameters (lactoferrin, superoxide dismutases) in serum of patients with Alzheimer's disease.
In this case/control study, serum levels of oxidative stress related parameters such as Fe-binding lactoferrin (LTF), Mn- and Zn,Cu-superoxide dismutase (SOD) were determined by enzyme linkedExpand

Neurotoxic effects on the dopaminergic system induced by TaClo (1-trichloromethyl-1,2,3,4-tetrahydro-β-carboline), a potential mammalian alkaloid : in vivo and in vitro studies
Due to their structural analogy to the dopaminergic neurotoxin MPTP (N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine), β-carbolines are discussed as potential natural inducers of Parkinson's diseaseExpand

Progressive Neurodegeneration of the Dopaminergic system and Inhibition of the Complex I Induced by the Chloral-Derived Tetrahydro-β-Carboline TaClo
TaClo (1-trichloromethyl-1,2,3,4-tetrahydro-β-carboline) appears to be a neurotoxic drug able to induce a slow developing degeneration of dopamine neurons. This is indicated from measurements of theExpand
