Although various derivatives of caffeic acid have been reported to possess a wide variety of biological activities such as protection of neuronal cells against excitotoxicity, the biological activity of 1-docosanoyl cafferate (DC) has not been examined. The objective of the present study was to evaluate the anti-inflammatory effects of DC, isolated from the(More)
Nitric oxide (NO) has both neuroprotective and neurotoxic effects depending on its concentration and the experimental model. We tested the effects of NG-nitro-L-arginine methyl ester (L-NAME), a nonselective nitric oxide synthase (NOS) inhibitor, and aminoguanidine, a selective inducible NOS (iNOS) inhibitor, on kainic acid (KA)-induced seizures and(More)
OBJECTIVE Fatigue can be caused by a deficiency of nutrition or immune function. The goal of this study was to identify the effects of porcine placenta extract (PPE) and its constituents, amino acids (glutamic acid, glycine, arginine, and proline), on protein-energy malnutrition (PEM)-induced fatigue.
