Objective(s) Methicillin-resistant Staphylococcus aureus (MRSA) is an important cause of nosocomial and community infections. Biofilm formation, mediated by a polysaccharide intercellular adhesin (PIA) and encoded by the ica operon, is considered to be an important virulence factor in both S. epidermidis and S. aureus. However, the clinical impact of the ica locus and PIA production is less w...

conclusions ica with trigeminal neuralgia and local neuropathic itch is very rarely encountered in clinical practice. as it is not always diagnosed at first, some patients miss the best treatment period. therefore, we call for emphasis to be placed on early diagnosis and timely surgical treatment. introduction intramedullary cavernous angioma (ica) is a rare lesion of the spinal cord, represent...

Mental workload is considered to be strongly linked human performance, and the ability measure it accurately key for balancing health work. In this study, brain signals were elicited by mental arithmetic tasks of varying difficulty stimulate different levels workload. addition, a finite impulse response (FIR) filter, independent component analysis (ICA), multiple artifact rejection algorithms (...

Se presenta un modelo de ecuaciones estructurales que relaciona las actitudes ambientales (ACA), intenciones comportamiento proambiental (ICA) y el (CPP) en estudiantes ingeniería e ingenieros activos. Las variables se relacionan mediante tres hipótesis son validadas estadísticamente con información obtenida 873 573 cuestionario, usa la técnica mínimos cuadrados parciales. Los resultados indica...

We demonstrate a novel technique for face recognition combined the independent component analysis (ICA) model with the optical correlation technique. Our approach relies on the performances of a strongly discriminating optical correlation method along with the robustness of the ICA model. Simulations were performed to illustrate how this algorithm can identify a face with images from the Pointi...

common anomalies of the carotid-basilar anastomoses. Persistent trigeminal artery variants originate directly from the precavernous portion of the internal carotid artery (ICA) and may be observed, usually as an incidental finding, in 0.1-1% of angiography or non-invasive vascular imaging studies.1 Little is known about the significance of the PPTA in occlusive cerebrovascular disease. We descr...

Meta-heuristic algorithms inspired by the natural processes are part of the optimization algorithms that they have been considered in recent years, such as genetic algorithm, particle swarm optimization, ant colony optimization, Firefly algorithm. Recently, a new kind of evolutionary algorithm has been proposed that it is inspired by the human sociopolitical evolution process. This new algorith...

To explore the pharmacokinetic properties of icariin (ICA) and icariside II (ICA II) following intragastric and intravenous administration in rats, a rapid and sensitive method by using ultra-performance liquid chromatography-tandem mass spectroscopy (UPLC-MS/MS) was developed and validated for the simultaneous quantification of ICA and ICA II in rat plasma. The quantification was performed by ...
