“…Probiotics strain bifidobacteria and lactobacilli have been reported to reverse PD conditions. The regular intake of fermented milk beverages containing the probiotic Lactobacillus casei shirota has been shown to improve the bowel movement and inhibit staphylococci growth in PD patients (Cassani et al, 2011). Probiotic bacterium Bacillus spp.…”

Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by neuronal loss and dysfunction of dopaminergic neurons located in the substantia nigra, which contain a variety of misfolded a-synuclein (a-syn). Medications that increase or substitute for dopamine can be used for the treatment of PD. Recently, numerous studies have shown gut microbiota plays a crucial role in regulating and maintaining multiple aspects of host physiology including host metabolism and neurodevelopment. In this review article, the role of gut microbiota in the etiological mechanism of PD will be reviewed. Furthermore, we discussed current pharmaceutical medicine-based methods to prevent and treat PD, followed by describing specific strains that affect the host brain function through the gut-brain axis. We explained in detail how gut microbiota directly produces neurotransmitters or regulate the host biosynthesis of neurotransmitters. The neurotransmitters secreted by the intestinal lumen bacteria may induce epithelial cells to release molecules that, in turn, can regulate neural signaling in the enteric nervous system and subsequently control brain function and behavior through the brain-gut axis. Finally, we proved that the microbial regulation of the host neuronal system. Endogenous a-syn can be transmitted long distance and bidirectional between ENS and brain through the circulatory system which gives us a new option that the possibility of altering the community of gut microbiota in completely new medication option for treating PD.

“…Industrial applications required high mechanical accuracy such as computer-numerical-control machines, robotics, electric vehicles utilizing permanent magnet synchronous motors (PMSMs) because of their high power, low moment of inertia, high start-up torque [1]. Similarly to induction motor drive (IMD), field-oriented-control (FOC) and direct torque control (DTC) strategies [2], [3] are used in high-performance torque and flux controls of PMSM drive [4], [5]. The DTC has a simpler structure than FOC, therefore its simulation and real implementation are easier than FOC.…”

The paper describes pulse-width-modulation (PWM) technique and Kalman filter (KF) process to improve performance of direct torque controlled permanent magnet synchronous motor (DTC-PMSM) drive. Performance of DTC methods are strongly affected by high stator current ripple. For lowering the ripple, high switching frequency space vector PWM and KF are utilized in the paper. Mathematical model of PMSM and calculations of important quantities of DTC applied to PMSM drive are presented in the ﬁrst part. The second part shows computation process of space vector PWM and KF. Performance indices are utilized to evaluate the drive structures. Theorectical assumptions are validated via simulations with Gaussian noised stator current measurement.
