Previous studies have demonstrated mixed inhibitory and facilitatory effects of 5-hydroxytryptamine-4 (5-HT(4)) receptor agonists on electrical field stimulation (EFS)-induced responses in human isolated colon. Here we report three types of responses to EFS in human isolated colon circular muscle: monophasic cholinergic contraction during EFS, biphasic(More)
5-Hydroxytryptamine (5-HT4) receptor agonists increase gastrointestinal (GI) motility by enhancing enteric acetylcholine release which is then metabolized by acetylcholinesterase (AChE) to inactive metabolites. As both AChE inhibitors and, more usually, 5-HT4 receptor agonists are used to increase GI motility, an understanding of how these two different(More)
Although sodium valproate (VPA)-induced hepatic encephalopathy is a well-recognized entity, VPA can occasionally produce encephalopathy secondary to hyperammonemia in the presence of normal hepatic function, namely valproate-induced non-hepatic hyperammonemic encephalopathy (VNHE). Known risk factors include therapy with multiple antiepileptic drugs,(More)
BACKGROUND Monomelic amyotrophy (MMA) is a benign motor neuron disorder, which particularly affects young people and the etiology is still unknown. Gangliosides are located on the outer surface of motor neurons. Anti-GM1 antibodies have been found to be elevated in multi-focal motor neuropathy with conduction block and other neurological diseases, which may(More)
This paper deals with the modeling of a Hansen's disease (HD) affected nerve using FEM based simulation tool. There exists an exponential delay in the propagation of action potential for a diseased nerve as compared to a healthy one. To include this exponential delay, the FitzHugh Nagumo equation has been modified and modeled using COMSOL Multiphysics 4.0a.(More)
This paper presents two different methods for detection of seizure in brain. Here we investigate the use of the Naïve Bayes classifier and Backpropagation neural network for the given signals. Naïve bayes is simple probabilistic classifier based on applying Bayes' theorem with independent assumptions. On the other hand Backpropogation (BPN) algorithm is a(More)
Due to research on social network, mobile commerce has received lot of interests. Mining and prediction of users' mobile commerce behaviors such as their movements and purchase transactions. In this paper, we propose a novel framework, called Social Engine, for mining and prediction of mobile users' movements and purchase transactions under mobile commerce(More)
Simplified active NPC (ANPC) inverters enable a substantially increased output power and an improved performance at zero speed for high-power electrical drives. This paper analyzes the operation of Simplified ANPC inverters under device failure conditions, and proposes the fault-tolerant strategies to enable continuous operating of the inverters and drive(More)
