Effects of MPTP, MPP(+) and Adreno-Medullin on Dopamine Metabolism in the Rat Corpus Striatum
… caused by MPTP and 1-methyl-4-phenylpyridine (MPP$\sp+$), an active metabolite of MPTP, have been demonstrated. First, oxidation of MPTP catalyzed by monoamine oxidase can generate hydrogen peroxide and other active oxygen species, which might then initiate oxidative damage to the cells. Also, …

Implantação de práticas seguras para o uso de medicamentos no Hospital Napoleão Laureano : elaboração de um guia farmacoterapêutico para a utilização dos MPP
… that become the most feared when committed with MPP (MPP). The MPPs are defined as a group of drugs that have an increased risk of d amage to bring the wearer. The cancer patients makes use of various drugs, adjuvant therapy, in addition to used in cancer treatment and therefore the focus of your …

The effects of Parkinson's disease mimetics on the proteasomal and neurofilament systems in SH-SY5Y cells
… neuroblastoma cells treated with the PD mimetics MPP+ (a complex I inhibitor) or dopamine. Treatment with these toxins led to dose and time dependent reductions in ATP and glutathione levels and also chymotrypsin-like and postacidic-like activities; however, trypsin-like activity was unaffected. …

Serotonergic and dopaminergic systems as targets for exogenous neurotoxins causing a parkinsonian syndrome
… of action of MPTP and its toxic metabolite, MPP⁺, and compared it to the mechanism of action of haloperidol metabolites, some of which are found in schizophrenic patients. Experiments assessed the effects of these compounds on several aspects of amine uptake in mouse brain synaptosomes. Both …

Multi-path Penalty metric in underwater acoustic communication for autonomy and human decision-making
… communication, called Multipath Penalty (MPP), is proposed as an alternative to traditional signal-to-noise ratio (SNR) methods in the context of the Arctic Beaufort Sea. MPP and SNR are compared alongside a third performance metric, Minimum Achievable Error (MAE), which replicates the …

Application of microperforated elements in axial fan noise control and silencer design
The microperforated panel (MPP) is considered to be an alternative sound absorbing material, which could replace the traditional glass fibers and other porous materials because of its sound absorbing characteristics in a wide frequency range. The MPP is also very useful in various human involved …

A study of the neurotoxicity of MPTP and analogs in human neuroblastoma SH-SY5Y cells
… (MPDP⁺) and 1-methyl-4-phenylpyridium (MPP⁺) by monoamine oxidase (MAO). MPP⁺, the neurotoxic analog of MPTP, was taken up into cells through a dopamine (DA) uptake mechanism. MPTP, via its metabolite MPP⁺, inhibited NADH dehydrogenase activity. The MPTP-induced alterations of morphology …

Algorithms and inference for simultaneous-event multivariate point-process, with applications to neural data
The formulation of multivariate point-process (MPP) models based on the Jacod likelihood does not allow for simultaneous occurrence of events at an arbitrarily small time resolution. In this thesis, we introduce two versatile representations of a simultaneous event multivariate point-process …
