The proposed work mainly involves three stages namely denoising, feature extraction and classification. The removal of noise from ECG signal is achieved by applying wavelet threshold technique. The extraction of clinically useful features is carried out through morphological technique, statistical analysis, principal component analysis (PCA)-based technique and independent component analysis-wavelet packet decomposition (ICA-WPD) technique. The extracted features are used as inputs for artificial neural network (ANN), support vector machines (SVM) and K-nearest neighbour (KNN) classifier models for detecting ischemic beats. The performance of all models are compared and validated with ECG signal acquired from physiobank database in terms of performance indices such as classification accuracy, sensitivity and positive prediction accuracy. The results have confirmed that the ANN model trained and tested with features extracted by ICA-WPD provides highest classification accuracy of 96.85%, PPA of 99.59% and sensitivity of 97.22%. Results clearly demonstrated that the ANN classifier model combined with ICA-WPD-based feature is more effective in diagnosing myocardial ischemia at early stages.","PeriodicalId":193362,"journal":{"name":"Int.

Hepatocytes, particularly, are highly specialised cells, their geometrical conformation, and their coculture with no parenquimal cells and vascularised tissue, are essential to their physiology and proper function. Polymeric scaffolds for cell growth have been modified through plasma polymerisation to improve their biological properties. This work presents a Poly (L-lactic acid) (PLLA) coated scaffold with polypyrrole plasma doped with iodine (Ppy-I). The scaffold where seeded with two different cell lines, hepatocytes (HepG2) with stellate cells (Ito), and hepatocytes (HepG2) with endothelial cells (HUVEC), the data were evaluated against control hepatocytes (HepG2) culture. The morphology of the cells was evaluated by microscopy; to corroborate the cell proliferation on the material, images of the samples with the cells were taking three times per week. Total protein in the supernatant was measured, and showed that in the endothelial coculture increased 25% the protein production and the stellate coculture increased 20% the protein production against the hepatocyte culture. In conclusion, we obtain a Ppy-I surface coculture that optimises the conditions for better liver models.","PeriodicalId":193362,"journal":{"name":"Int. J. Medical Eng.

Twelve healthy preterm infants were studied using a within-subject cross over design to compare semi-upright and the elevated sidelying position during bottle feeding. Outcome measures were physiologic indicators of cardiopulmonary status: heart rate, respiratory rate, oxygen saturation and respiratory pattern variability. Preliminary results suggest that analysis of respiratory waveform variability is feasible and may be a more sensitive measure of cardiopulmonary physiology than means for heart rate, respiratory rate and percent haemoglobin oxygen saturation. Nonlinear methods of analysis of the respiratory data provide a distinct perspective on the adaptability of infants' breathing patterns while feeding. The clinical application of monitoring respiratory waveforms using nonlinear methods may be helpful in identifying readiness to initiate and advance feeds orally in preterm infants.","PeriodicalId":193362,"journal":{"name":"Int.
