The effect of the alkaloid 1-(phenyl)-N'-(4-methoxybenzylidene)- 9H-pyrido[3,4-b]indole-3-carbohydrazide (PMC) on the poliovirus (PV) replication cycle in Vero cells was assayed by inhibition of the cytopathic effect (CPE) and inhibition of plaque forming units (PFU). Both methodologies suggested that the mode of action was avoidance of infection progression in the host cell. The compound was a...
introduction : although many protocols are available in the field of the prehospital medical care (pmc), there is still a notable gap between protocol based directions and applied clinical practice. this study measures the rate of protocol adherence in pmc provided for patients with chest pain and loss of consciousness (loc). method : in this cross-sectional study, 10 educated research assistan...
OBJECTIVES This study was designed to determine predictors of restenosis after successful percutaneous mitral commissurotomy (PMC) and its relationship to late clinical outcome. BACKGROUND The restenosis rate after PMC and its relationship to late clinical outcome is poorly defined. METHODS Serial echocardiography was performed in 310 patients who underwent PMC. Restenosis, defined as mitra...
STUDY DESIGN This study was a retrospective, multicenter cohort study. OBJECTIVES Rare complications of cervical spine surgery are inherently difficult to investigate. Pseudomeningocoele (PMC), an abnormal collection of cerebrospinal fluid that communicates with the subarachnoid space, is one such complication. In order to evaluate and better understand the incidence, presentation, treatment,...
BACKGROUND Indications of percutaneous mitral commissurotomy (PMC) remain debated in calcific mitral stenosis. We analyzed long-term results of PMC for calcific mitral stenosis and the factors associated with late functional results. METHODS AND RESULTS We compared the characteristics and outcome of 314 patients undergoing PMC for calcific mitral stenosis with 710 patients with noncalcified v...
The authors describe an Italian kindred with nine individuals affected by hyperkalaemic periodic paralysis associated with paramyotonia congenita (hyperPP/PMC). Periodic paralysis was particularly severe, with several episodes a day lasting for hours. The onset of episodes was unusually early, beginning in the first year of life and persisting into adult life. The paralytic episodes were refrac...
For robust speech recognition in noisy environments, various methods have been studied. In this paper, we apply parallel model combination (PMC) for segmental unit input HMM to recognize corrupted speech in additive noise. Since several successive frames are combined and treated as an input vector in segmental unit input modeling, the increased dimension of vector degrades the precision in esti...
Experimental results for imaging the low-scattering tissue phantoms based on the derivative estimation through perturbation Monte-Carlo (pMC) method are presented. It is proven that pMC-based methods give superior reconstructions compared to diffusion-based reconstruction methods. An easy way to estimate the Jacobian using analytical expression obtained from perturbation Monte-Carlo method is e...
We propose a new model called a Pairwise Markov Chain (PMC), which generalizes the classical Hidden Markov Chain (HMC) model. The generalization, which allows one to model more complex situations, in particular implies that in PMC the hidden process is not necessarily a Markov process. However, PMC allows one to use the classical Bayesian restoration methods like Maximum A Posteriori (MAP), or ...
Although right- and left-hand motor imagery (MI) typically results in lateralized cortical activation patterns in various areas, such an effect has never been observed in the left premotor cortex (PMC). Using functional magnetic resonance imaging we tested whether the left PMC, which is supposed to be effector independent, i.e. it is activated irrespective of the hand used for MI, shows differe...
