background: cyclosporine a (csa) is an immunosuppressant with therapeutic indications in various immunological diseases; however, its use is associated with chronic nephropathy. oxidative stress has a crucial role in csa-induced nephrotoxicity. the present study evaluates the protective effect of edaravone on csa-induced chronic nephropathy and investigates its antioxidant and nitric oxide modu...
We propose an algorithm for use with multisensor systems that is capable of the following: a) identify an analyte independently of its concentration; b) estimate the concentration of the analyte, even if the system was not previously exposed to this concentration; c) tell when an analyte is of a chemical type not previously presented to the system. The algorithm, based upon recent work of Hopfi...
A quantitative procedure was developed to predict the composition of ternary ground spice mixtures using an electronic nose. Basil, cinnamon, and garlic were mixed in different compositions and presented to an enose. Nineteen training mixtures were used to build predictive models. Model performance was tested using 5 other mixtures. Three neural network structures—multilayer perceptron (MLP), M...
BACKGROUND Alzheimer's disease (AD) is diagnosed based upon medical history, neuropsychiatric examination, cerebrospinal fluid analysis, extensive laboratory analyses and cerebral imaging. Diagnosis is time consuming and labour intensive. Parkinson's disease (PD) is mainly diagnosed on clinical grounds. OBJECTIVE The primary aim of this study was to differentiate patients suffering from AD, P...
An electronic nose is a device that performs the electronic olfactory to substitute human experts. The development of these devices is growing faster due to higher demand. Electronic nose is the mimicking of human nose. Electronic-nose devices have received considerable attention in the field of sensor technology during the past twenty years, largely due to the discovery of numerous application...
An electronic nose (e-nose) was used to establish a freshness evaluation model for pork. A pre-experiment was performed to acquire optimum parameters (10 g sample mass with 5 min headspace-generation time in 500 mL vial) for later e-nose detection of pork. Responding signals of the enose were extracted and analyzed. Linear Discriminant Analysis (LDA) results showed that the e-nose could classif...
