Journal ArticleDOI
New approaches in clinical chemistry: on-line analyte concentration and microreaction capillary electrophoresis for the determination of drugs, metabolic intermediates, and biopolymers in biological fluids.
Norberto A. Guzman,SungAe S. Park,Daniel E. Schaufelberger,Luis Hernandez,Ximena Páez,Pedro Rada,Andy J. Tomlinson,Stephen Naylor +7 more
TL;DR: The likely impact of the technology of capillary electrophoresis and the role of the CE analyte concentrator-microreactor on the analysis of biomolecules, present on complex matrices, in a clinical laboratory is reviewed.
Journal ArticleDOI
Toxoplasma gondii infection lower anxiety as measured in the plus-maze and social interaction tests in rats A behavioral analysis.
Luis E. Gonzalez,Belen Rojnik,Franklin Urrea,Haydee Urdaneta,Pierina Petrosino,Cesare Colasante,Silvano Pino,Luis Hernandez +7 more
TL;DR: The hypothesis that T. gondii impairs mechanism of warning as a function of reduced anxiety is supported and the pattern of brain colonization by the parasite and the host immune response suggests that the predominant invasion to limbic areas works as a natural anxiolytic mechanism.
Journal ArticleDOI
Medial prefrontal transection enhances social interaction. I: behavioral studies.
Luis E. Gonzalez,Maria Rujano,Sonia Tucci,Daniel Paredes,Elizabeth Silva,German Alba,Luis Hernandez +6 more
TL;DR: Results suggest that the MPFC would be implicated in a generalized mechanism of warning enabling emission of appropriate responses to anxiogenic stimuli, and the pattern of the motor activation induced by amphetamine was altered.
Journal ArticleDOI
Effect of precipitated withdrawal on extracellular glutamate and aspartate in the nucleus accumbens of chronically morphine-treated rats: an in vivo microdialysis study.
TL;DR: It is suggested that excitatory amino acid release in the nucleus accumbens might play a role in morphine withdrawal.
Journal ArticleDOI
In vivo monitoring of glutamate in the brain by microdialysis and capillary electrophoresis with laser-induced fluorescence detection
TL;DR: These experiments support the hypothesis that dopamine receptor blockade decreases glutamate release, and the potential of capillary electrophoresis and laser-induced fluorescence detection for the study of chemicals in biomedical experiments is discussed.
