Advanced food processing methods that accomplish inactivation of microorganisms but minimize adverse thermal exposure are of great interest to the food industry. High pressure (HP) and pulsed electric field (PEF) processing are commercially applied to produce high quality fruit and vegetable products in the United States, Europe, and Japan. Both microbial(More)

The present work focuses on the physiopathology of Parkinson's disease (PD), analyzing the alterations in neuro-transmitter profile of the basal ganglia triggered by the degeneration of cells from the substantia nigra compacta (SNpc). For this purpose, the neurochemical, morphological and molecular changes of the pedunculopontine nucleus (PPN) of rats upon(More)
Previous research has documented that negative experiences in chemistry courses are a major factor that discourages many students from continuing in premedical studies. This adverse impact affects women and students from under-represented minority (URM) groups disproportionately. To determine if chemistry courses have a similar effect at a large public(More)

The effect of the systemic administration of MK-801, an antagonist of N-methyl-D-aspartate (NMDA) receptors, was(More)
Efecto neuroprotector de la administración sistémica de MK-801 en el núcleo pedunculopontino de ratas hemiparkinsonizadas ABSTRACT Neuroprotective effects of MK-801 systemic administration on the pedunculopontine nucleus of hemiparkinsonian rats. Some glutamatergic antagonists have been administered as part of the pharmacologic strategies direct towards at(More)
Increase in the extracellular concentration of amino acid neurotransmitters and cell death on the pedunculopontine nucleus of hemiparkinsonian rats upon intracerebral injection of 6-hydroxy dopamine ABSTRACT Although the dysfunctions of the pedunculopontine nucleus (PPN) have been linked in the last decade to the physiopathology of Parkinson's disease (PD),(More)
