However, present studies had not addressed approaches for noninvasive measurement in order to evaluate therapeutic effect of acupuncture. The purpose of this study is to propose a noninvasive method to evaluate acupuncture by measuring facial temperature through thermal image. Three human subjects were recruited in this study. Each subject received acupuncture therapy for 30 mins. Acupuncture needles (Ø0.16 x 30 mm) were inserted into Baihui point (DU20), Neiguan points (PC6) and Taichong points (LR3), acupuncture needles (Ø0.18 x 39 mm) were inserted into Tanzhong point (RN17), Zusanli points (ST36) and Yinlingquan points (SP9). Facial temperature was recorded by an infrared thermometer. Acupuncture therapeutic effect was compared pre- and post-acupuncture. Experiment results demonstrated that facial temperature changed according to acupuncture therapeutic effect. It was concluded that proposed method showed high potential to evaluate acupuncture by noninvasive measurement of facial temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acupuncture" title="acupuncture">acupuncture</a>, <a href="https://publications.waset.org/abstracts/search?q=facial%20temperature" title=" facial temperature"> facial temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=noninvasive%20evaluation" title=" noninvasive evaluation"> noninvasive evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20image" title=" thermal image"> thermal image</a> </p> <a href="https://publications.waset.org/abstracts/95222/noninvasive-evaluation-of-acupuncture-by-measuring-facial-temperature-through-thermal-image" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95222.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">68</span> Noninvasive Disease Diagnosis through Breath Analysis Using DNA-functionalized SWNT Sensor Array</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20J.%20Zhang">W.

The volatile organic compounds (VOCs) in exhaled breath, which are mainly blood borne, particularly provide highly valuable information about individuals’ physiological and pathophysiological conditions. Additionally, breath analysis is noninvasive, real-time, painless and agreeable to patients. We have developed a wireless sensor array based on single-stranded DNA (ssDNA)-decorated single-walled carbon nanotubes (SWNT) for the detection of a number of physiological indicators in breath. Eight DNA sequences were used to functionalize SWNT sensors to detect trace amount of methanol, benzene, dimethyl sulfide, hydrogen sulfide, acetone and ethanol, which are indicators of heavy smoking, excessive drinking, and diseases such as lung cancer, breast cancer, cirrhosis and diabetes. Our tests indicated that DNA functionalized SWNT sensors exhibit great selectivity, sensitivity, reproducibility, and repeatability. Furthermore, different molecules can be distinguished through pattern recognition enabled by this sensor array. Thus, the DNA-SWNT sensor array has great potential to be applied in chemical or bimolecular detection for the noninvasive diagnostics of diseases and health monitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breath%20analysis" title="breath analysis">breath analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA-SWNT%20sensor%20array" title=" DNA-SWNT sensor array"> DNA-SWNT sensor array</a>, <a href="https://publications.waset.org/abstracts/search?q=noninvasive" title=" noninvasive"> noninvasive</a> </p> <a href="https://publications.waset.org/abstracts/36968/noninvasive-disease-diagnosis-through-breath-analysis-using-dna-functionalized-swnt-sensor-array" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">348</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">67</span> Noninvasive Neurally Adjusted Ventilation versus Nasal Continuous or Intermittent Positive Airway Pressure for Preterm Infants: A Systematic Review and Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20S.%20Bhader">Mohammed S.

The aim of this systematic review was to compare NAVA to nasal continuous or positive airway pressure (NCPAP) or intermittent positive airway pressure (NIPP) for preterm infants. Methods: We searched the online databases Medline, Embase, and CENTRAL. We included randomized controlled trials (RCTs) that compared NAVA to NCPAP or NIPP for preterm infants < 37 weeks gestational age. We sought to evaluate the following outcomes: noninvasive intubation failure rate, desaturation rate, the fraction of inspired oxygen (FiO2), and length of stay in the neonatal intensive care unit (NICU). We used the mean difference (MD) to represent continuous outcomes, while the odds ratio (OR) was used to represent dichotomous outcomes. Results: A total of 11 RCTs that enrolled 429 preterm infants were deemed eligible. NAVA showed similar clinical outcomes to NCPAP or NIPP with respect to noninvasive intubation failure (RR for NAVA versus NCPAP: 0.82, 95% confidence interval (CI): 0.49 to 1.37), desaturation rate (RR for NAVA versus NCPAP: 0.69, 95%CI: 0.36 to 1.29; RR for NAVA versus NIPP: 0.58, 95%CI: 0.08 to 4.25), FiO2 (MD for NAVA versus NCPAP: –0.01, 95%CI: –0.04 to 0.02; MD for NAVA versus NIPP: –7.16, 95%CI: –22.63 to 8.31), and length of stay in the NICU (MD for NAVA versus NCPAP: 1.34, 95%CI: –4.17 to 6.85). Conclusion: NAVA showed similar clinical and ventilator-related outcomes compared to the usual care noninvasive respiratory support measures NCPAP or NIPP for preterm infants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=preterm%20infants" title="preterm infants">preterm infants</a>, <a href="https://publications.waset.org/abstracts/search?q=noninvasive%20neurally%20adjusted%20ventilatory%20assist" title=" noninvasive neurally adjusted ventilatory assist"> noninvasive neurally adjusted ventilatory assist</a>, <a href="https://publications.waset.org/abstracts/search?q=NIV-NAVA" title=" NIV-NAVA"> NIV-NAVA</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive%20ventilation" title=" non-invasive ventilation"> non-invasive ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=nasal%20continuous%20or%20positive%20airway%20pressure" title=" nasal continuous or positive airway pressure"> nasal continuous or positive airway pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=NCPAP" title=" NCPAP"> NCPAP</a>, <a href="https://publications.waset.org/abstracts/search?q=intermittent%20positive%20airway%20pressure%20ventilation" title=" intermittent positive airway pressure ventilation"> intermittent positive airway pressure ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=NIPP" title=" NIPP"> NIPP</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20distress%20syndrome" title=" respiratory distress syndrome"> respiratory distress syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=RDS" title=" RDS"> RDS</a> </p> <a href="https://publications.waset.org/abstracts/157200/noninvasive-neurally-adjusted-ventilation-versus-nasal-continuous-or-intermittent-positive-airway-pressure-for-preterm-infants-a-systematic-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157200.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">109</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> The Biochemical and Radiographic Evaluation of the Non-Metastatic Bone Disease in Patients with Renal Cell Carcinoma Undergoing Hemodialysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aliakbar%20Hafezi">Aliakbar Hafezi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalal%20Taherian"> Jalal Taherian</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamshid%20Abedi"> Jamshid Abedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Elahi"> Mahsa Elahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Bones are commonly affected by renal cell carcinoma (RCC) (primarily or secondary), and this condition causes bone fragility. The aim of this study was to evaluate the diagnostic value of noninvasive methods for the diagnosis of ROD in RCC patients on hemodialysis (HD) in northern Iran. Methods: In this cross-sectional study, 50 RCC patients with ESRD referred to dialysis units in northern Iran during 2021-2024 were randomly selected and investigated. The biochemical and radiographic evaluation of ROD and its subtypes was performed, and then all patients underwent bone biopsy and histopathological study, and finally, the diagnostic value of the noninvasive methods was assessed. Results: The mean age of patients was 58.9 ± 11.7 years, and 27 cases (54.0%) were female. 38 (76.0%) of RCC patients with ESRD had ROD, and 12 patients (24.0%) had no evidence of bone disorders. The sensitivity, specificity, positive and predictive values and accuracy of the noninvasive methods for the diagnosis of ROD were 92%, 82%, 95%, 75% and 90%, respectively. Conclusion: This study showed that the frequency of ROD in RCC patients with ESRD in northern Iran was high and the biochemical and radiographic markers have a high diagnostic value for ROD as well as histopathological assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renal%20cell%20carcinoma" title="renal cell carcinoma">renal cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=renal%20osteodystrophy" title=" renal osteodystrophy"> renal osteodystrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=hemodialysis" title=" hemodialysis"> hemodialysis</a>, <a href="https://publications.waset.org/abstracts/search?q=non-metastatic" title=" non-metastatic"> non-metastatic</a> </p> <a href="https://publications.waset.org/abstracts/194684/the-biochemical-and-radiographic-evaluation-of-the-non-metastatic-bone-disease-in-patients-with-renal-cell-carcinoma-undergoing-hemodialysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194684.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">6</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Development of Noninvasive Method to Analyze Dynamic Changes of Matrix Stiffness and Elasticity Characteristics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elena%20Petersen">Elena Petersen</a>, <a href="https://publications.waset.org/abstracts/search?q=Inna%20Kornienko"> Inna Kornienko</a>, <a href="https://publications.waset.org/abstracts/search?q=Svetlana%20Guryeva"> Svetlana Guryeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Dobdin"> Sergey Dobdin</a>, <a href="https://publications.waset.org/abstracts/search?q=Anatoly%20Skripal"> Anatoly Skripal</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrey%20Usanov"> Andrey Usanov</a>, <a href="https://publications.waset.org/abstracts/search?q=Dmitry%20Usanov"> Dmitry Usanov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the most important unsolved problems in modern medicine is the increase of chronic diseases that lead to organ dysfunction or even complete loss of function. Current methods of treatment do not result in decreased mortality and disability statistics. Currently, the best treatment for many patients is still transplantation of organs and/or tissues. Therefore, finding a way of correct artificial matrix biofabrication in case of limited number of natural organs for transplantation is a critical task. One important problem that needs to be solved is development of a nondestructive and noninvasive method to analyze dynamic changes of mechanical characteristics of a matrix with minimal side effects on the growing cells. This research was focused on investigating the properties of matrix as a marker of graft condition. In this study, the collagen gel with human primary dermal fibroblasts in suspension (60, 120, 240*103 cells/mL) and collagen gel with cell spheroids were used as model objects. The stiffness and elasticity characteristics were evaluated by a semiconductor laser autodyne. The time and cell concentration dependency of the stiffness and elasticity were investigated. It was shown that these properties changed in a non-linear manner with respect to cell concentration. The maximum matrix stiffness was observed in the collagen gel with the cell concentration of 120*103 cells/mL. This study proved the opportunity to use the mechanical properties of matrix as a marker of graft condition, which can be measured by noninvasive semiconductor laser autodyne technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graft" title="graft">graft</a>, <a href="https://publications.waset.org/abstracts/search?q=matrix" title=" matrix"> matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=noninvasive%20method" title=" noninvasive method"> noninvasive method</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative%20medicine" title=" regenerative medicine"> regenerative medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductor%20laser%20autodyne" title=" semiconductor laser autodyne"> semiconductor laser autodyne</a> </p> <a href="https://publications.waset.org/abstracts/65673/development-of-noninvasive-method-to-analyze-dynamic-changes-of-matrix-stiffness-and-elasticity-characteristics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65673.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">64</span> Diagnostic Value of Different Noninvasive Criteria of Latent Myocarditis in Comparison with Myocardial Biopsy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olga%20Blagova">Olga Blagova</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuliya%20Osipova"> Yuliya Osipova</a>, <a href="https://publications.waset.org/abstracts/search?q=Evgeniya%20Kogan"> Evgeniya Kogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Nedostup"> Alexander Nedostup</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: to quantify the value of various clinical, laboratory and instrumental signs in the diagnosis of myocarditis in comparison with morphological studies of the myocardium. Methods: in 100 patients (65 men, 44.7±12.5 years) with «idiopathic» arrhythmias (n = 20) and dilated cardiomyopathy (DCM, n = 80) were performed 71 endomyocardial biopsy (EMB), 13 intraoperative biopsy, 5 study of explanted hearts, 11 autopsy with virus investigation (real-time PCR) of the blood and myocardium. Anti-heart antibodies (AHA) were also measured as well as cardiac CT (n = 45), MRI (n = 25), coronary angiography (n = 47). The comparison group included of 50 patients (25 men, 53.7±11.7 years) with non-inflammatory heart diseases who underwent open heart surgery. Results. Active/borderline myocarditis was diagnosed in 76.0% of the study group and in 21.6% of patients of the comparison group (p < 0.001). The myocardial viral genome was observed more frequently in patients of comparison group than in study group (group (65.0% and 40.2%; p < 0.01. Evaluated the diagnostic value of noninvasive markers of myocarditis. The panel of anti-heart antibodies had the greatest importance to identify myocarditis: sensitivity was 81.5%, positive and negative predictive value was 75.0 and 60.5%. It is defined diagnostic value of non-invasive markers of myocarditis and diagnostic algorithm providing an individual assessment of the likelihood of myocarditis is developed. Conclusion. The greatest significance in the diagnosis of latent myocarditis in patients with 'idiopathic' arrhythmias and DCM have AHA. The use of complex of noninvasive criteria allows estimate the probability of myocarditis and determine the indications for EMB. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=myocarditis" title="myocarditis">myocarditis</a>, <a href="https://publications.waset.org/abstracts/search?q=%22idiopathic%22%20arrhythmias" title=" "idiopathic" arrhythmias"> "idiopathic" arrhythmias</a>, <a href="https://publications.waset.org/abstracts/search?q=dilated%20cardiomyopathy" title=" dilated cardiomyopathy"> dilated cardiomyopathy</a>, <a href="https://publications.waset.org/abstracts/search?q=endomyocardial%20biopsy" title=" endomyocardial biopsy"> endomyocardial biopsy</a>, <a href="https://publications.waset.org/abstracts/search?q=viral%20genome" title=" viral genome"> viral genome</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-heart%20antibodies" title=" anti-heart antibodies"> anti-heart antibodies</a> </p> <a href="https://publications.waset.org/abstracts/83648/diagnostic-value-of-different-noninvasive-criteria-of-latent-myocarditis-in-comparison-with-myocardial-biopsy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83648.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Assessment of Hepatosteatosis Among Diabetic and Nondiabetic Patients Using Biochemical Parameters and Noninvasive Imaging Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tugba%20Sevinc%20Gamsiz">Tugba Sevinc Gamsiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Koroglu"> Emine Koroglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozcan%20Keskin"> Ozcan Keskin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Nonalcoholic fatty liver disease (NAFLD) is considered the most common chronic liver disease in the general population.

Materials and Methods: The study was conducted from (September 2017) to (December 2017) on adults admitted to Internal Medicine and Gastroenterology outpatient clinics with hepatic steatosis reported on ultrasound or transient elastography within the last six months that exclude patients with other liver diseases or alcohol abuse. The data were collected and analyzed retrospectively. Number cruncher statistical system (NCSS) 2007 program was used for statistical analysis. Results: 116 patients were included in this study. Diabetic patients compared to nondiabetics had significantly higher Controlled Attenuation Parameter (CAP), Liver Stiffness Measurement (LSM) and fibrosis values. Also, hypertension, hepatomegaly, high BMI, hypertriglyceridemia, hyperglycemia, high A1c, and hyperuricemia were found to be risk factors for NAFLD progression to fibrosis. Advanced fibrosis (F3, F4) was present in 18,6 % of all our patients; 35,8 % of diabetic and 5,7 % of nondiabetic patients diagnosed with hepatic steatosis. Conclusion: Transient elastography is now used in daily clinical practice as an accurate noninvasive tool during follow-up of patients with fatty liver. Early diagnosis of the stage of liver fibrosis improves the monitoring and management of patients, especially in those with metabolic syndrome criteria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes" title="diabetes">diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=elastography" title=" elastography"> elastography</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20liver" title=" fatty liver"> fatty liver</a>, <a href="https://publications.waset.org/abstracts/search?q=fibrosis" title=" fibrosis"> fibrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20syndrome" title=" metabolic syndrome"> metabolic syndrome</a> </p> <a href="https://publications.waset.org/abstracts/98077/assessment-of-hepatosteatosis-among-diabetic-and-nondiabetic-patients-using-biochemical-parameters-and-noninvasive-imaging-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98077.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Noninvasive Continuous Glucose Monitoring Device Using a Photon-Assisted Tunneling Photodetector Based on a Quantum Metal-Oxide-Semiconductor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wannakorn%20Sangthongngam">Wannakorn Sangthongngam</a>, <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Huerta"> Melissa Huerta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaewoo%20Kim"> Jaewoo Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Doyeon%20Kim"> Doyeon Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Continuous glucose monitoring systems are essential for diabetics to avoid health complications but come at a costly price, especially when insurance does not fully cover the diabetic testing kits needed. This paper proposes a noninvasive continuous glucose monitoring system to provide an accessible, low-cost, and painless alternative method of accurate glucose measurements to help improve quality of life. Using a light source with a wavelength of 850nm illuminates the fingertip for the photodetector to detect the transmitted light. Utilizing SeeDevice’s photon-assisted tunneling photodetector (PAT-PD)-based QMOS™ sensor, fluctuations of voltage based on photon absorption in blood cells are comparable to traditional glucose measurements. The performance of the proposed method was validated using 4 test participants’ transmitted voltage readings compared with measurements obtained from the Accu-Chek glucometer. The proposed method was able to successfully measure concentrations from linear regression calculations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20glucose%20monitoring" title="continuous glucose monitoring">continuous glucose monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive%20continuous%20glucose%20monitoring" title=" non-invasive continuous glucose monitoring"> non-invasive continuous glucose monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=NIR" title=" NIR"> NIR</a>, <a href="https://publications.waset.org/abstracts/search?q=photon-assisted%20tunneling%20photodetector" title=" photon-assisted tunneling photodetector"> photon-assisted tunneling photodetector</a>, <a href="https://publications.waset.org/abstracts/search?q=QMOS%E2%84%A2" title=" QMOS™"> QMOS™</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20device" title=" wearable device"> wearable device</a> </p> <a href="https://publications.waset.org/abstracts/174019/noninvasive-continuous-glucose-monitoring-device-using-a-photon-assisted-tunneling-photodetector-based-on-a-quantum-metal-oxide-semiconductor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174019.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">61</span> Noninvasive Brain-Machine Interface to Control Both Mecha TE Robotic Hands Using Emotiv EEG Neuroheadset</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adrienne%20Kline">Adrienne Kline</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaydip%20Desai"> Jaydip Desai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electroencephalogram (EEG) is a noninvasive technique that registers signals originating from the firing of neurons in the brain. The Emotiv EEG Neuroheadset is a consumer product comprised of 14 EEG channels and was used to record the reactions of the neurons within the brain to two forms of stimuli in 10 participants. These stimuli consisted of auditory and visual formats that provided directions of ‘right’ or ‘left.’ Participants were instructed to raise their right or left arm in accordance with the instruction given. A scenario in OpenViBE was generated to both stimulate the participants while recording their data. In OpenViBE, the Graz Motor BCI Stimulator algorithm was configured to govern the duration and number of visual stimuli. Utilizing EEGLAB under the cross platform MATLAB®, the electrodes most stimulated during the study were defined. Data outputs from EEGLAB were analyzed using IBM SPSS Statistics® Version 20. This aided in determining the electrodes to use in the development of a brain-machine interface (BMI) using real-time EEG signals from the Emotiv EEG Neuroheadset. Signal processing and feature extraction were accomplished via the Simulink® signal processing toolbox.

The proposed method uses antibody conjugated iron oxide nanoparticles and multicolor Magnetic Particle Imaging (mMPI). The method has the potential for radiation exposure free real-time estimation of local tumor marker concentrations in vivo. In this study, the method is applied to human Alpha-1-Fetoprotein. Materials and Methods: As tracer material AFP antibody-conjugated Dendrimer-Fe3O4 nanoparticles were used. The nanoparticle bioconjugates were then incubated with bovine serum albumin (BSA) to block any possible nonspecific binding sites. Parts of the resulting solution were then incubated with AFP antigen. MPI measurements were done using the preclinical MPI scanner (Bruker Biospin MRI GmbH) and the multicolor method was used for image reconstruction. Results: In multicolor MPI images the nanoparticles incubated only with BSA were clearly distinguished from nanoparticles incubated with BSA and AFP antigens. Conclusion: Tomographic imaging of human tumor marker Alpha-1-Fetoprotein is possible using AFP antibody conjugated iron oxide nanoparticles in presence of BSA. This opens interesting perspectives for cancer diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=noninvasive%20imaging" title="noninvasive imaging">noninvasive imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20antigens" title=" tumor antigens"> tumor antigens</a>, <a href="https://publications.waset.org/abstracts/search?q=antibody%20conjugated%20iron%20oxide%20nanoparticles" title=" antibody conjugated iron oxide nanoparticles"> antibody conjugated iron oxide nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=multicolor%20magnetic%20particle%20imaging" title=" multicolor magnetic particle imaging"> multicolor magnetic particle imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20diagnosis" title=" cancer diagnosis"> cancer diagnosis</a> </p> <a href="https://publications.waset.org/abstracts/73134/first-experimental-evidence-on-feasibility-of-molecular-magnetic-particle-imaging-of-tumor-marker-alpha-1-fetoprotein-using-antibody-conjugated-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73134.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">59</span> Developing Optical Sensors with Application of Cancer Detection by Elastic Light Scattering Spectroscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=May%20Fadheel%20Estephan">May Fadheel Estephan</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20Perks"> Richard Perks</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Context: Cancer is a serious health concern that affects millions of people worldwide. Early detection and treatment are essential for improving patient outcomes. However, current methods for cancer detection have limitations, such as low sensitivity and specificity. Research Aim: The aim of this study was to develop an optical sensor for cancer detection using elastic light scattering spectroscopy (ELSS). ELSS is a noninvasive optical technique that can be used to characterize the size and concentration of particles in a solution. Methodology: An optical probe was fabricated with a 100-μm-diameter core and a 132-μm centre-to-centre separation. The probe was used to measure the ELSS spectra of polystyrene spheres with diameters of 2, 0.8, and 0.413 μm. The spectra were then analysed to determine the size and concentration of the spheres. Findings: The results showed that the optical probe was able to differentiate between the three different sizes of polystyrene spheres. The probe was also able to detect the presence of polystyrene spheres in suspension concentrations as low as 0.01%. Theoretical Importance: The results of this study demonstrate the potential of ELSS for cancer detection. ELSS is a noninvasive technique that can be used to characterize the size and concentration of cells in a tissue sample. This information can be used to identify cancer cells and assess the stage of the disease. Data Collection: The data for this study were collected by measuring the ELSS spectra of polystyrene spheres with different diameters. The spectra were collected using a spectrometer and a computer. Analysis Procedures: The ELSS spectra were analysed using a software program to determine the size and concentration of the spheres. The software program used a mathematical algorithm to fit the spectra to a theoretical model. Question Addressed: The question addressed by this study was whether ELSS could be used to detect cancer cells. The results of the study showed that ELSS could be used to differentiate between different sizes of cells, suggesting that it could be used to detect cancer cells. Conclusion: The findings of this research show the utility of ELSS in the early identification of cancer. ELSS is a noninvasive method for characterizing the number and size of cells in a tissue sample. To determine cancer cells and determine the disease's stage, this information can be employed. Further research is needed to evaluate the clinical performance of ELSS for cancer detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=elastic%20light%20scattering%20spectroscopy" title="elastic light scattering spectroscopy">elastic light scattering spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=polystyrene%20spheres%20in%20suspension" title=" polystyrene spheres in suspension"> polystyrene spheres in suspension</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20probe" title=" optical probe"> optical probe</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre%20optics" title=" fibre optics"> fibre optics</a> </p> <a href="https://publications.waset.org/abstracts/167454/developing-optical-sensors-with-application-of-cancer-detection-by-elastic-light-scattering-spectroscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167454.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">58</span> Agarose Amplification Based Sequencing (AG-seq) Characterization Cell-free RNA in Preimplantation Spent Embryo Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huajuan%20Shi">Huajuan Shi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The biopsy of the preimplantation embryo may increase the potential risk and concern of embryo viability.

Receptor positivity like epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) genotyping are critical in lung adenocarcinoma for treatment. As conventional identification of receptor positivity is an invasive procedure, we analyzed the features on non-invasive computed tomography (CT), which predicts the receptor positivity in lung adenocarcinoma. Retrospectively, we did a comprehensive study from 77 proven lung adenocarcinoma patients with CT images, EGFR and ALK receptor genotyping, and clinical information. Total 22/77 patients were receptor-positive (15 had only EGFR mutation, 6 had ALK mutation, and 1 had both EGFR and ALK mutation). Various morphological characteristics and metastatic distribution on CT were analyzed along with the clinical information. Univariate and multivariable logistic regression analyses were used. On multivariable logistic regression analysis, we found spiculated margin, lymphangitic spread, air bronchogram, pleural effusion, and distant metastasis had a significant predictive value for receptor mutation status. On univariate analysis, air bronchogram and pleural effusion had significant individual predictive value. Conclusions: Receptor positive lung cancer has characteristic imaging features compared with nonreceptor positive lung adenocarcinoma. Since CT is routinely used in lung cancer diagnosis, we can predict the receptor positivity by a noninvasive technique and would follow a more aggressive algorithm for evaluation of distant metastases as well as for the treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title="lung cancer">lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=multidisciplinary%20cancer%20care" title=" multidisciplinary cancer care"> multidisciplinary cancer care</a>, <a href="https://publications.waset.org/abstracts/search?q=oncologic%20imaging" title=" oncologic imaging"> oncologic imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=radiobiology" title=" radiobiology"> radiobiology</a> </p> <a href="https://publications.waset.org/abstracts/129528/role-of-imaging-in-predicting-the-receptor-positivity-status-in-lung-adenocarcinoma-a-chapter-in-radiogenomics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129528.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Assessment of Cellular Metabolites and Impedance for Early Diagnosis of Oral Cancer among Habitual Smokers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ripon%20Sarkar">Ripon Sarkar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kabita%20Chaterjee"> Kabita Chaterjee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ananya%20Barui"> Ananya Barui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Smoking is one of the leading causes of oral cancer. Cigarette smoke affects various cellular parameters and alters molecular metabolism of cells. Epithelial cells losses their cytoskeleton structure, membrane integrity, cellular polarity that subsequently initiates the process of epithelial cells to mesenchymal transition due to long exposure of cigarette smoking. It changes the normal cellular metabolic activity which induces oxidative stress and enhances the reactive oxygen spices (ROS) formation. Excessive ROS and associated oxidative stress are considered to be a driving force in alteration in cellular phenotypes, polarity distribution and mitochondrial metabolism. Noninvasive assessment of such parameters plays essential role in development of routine screening system for early diagnosis of oral cancer. Electrical cell-substrate impedance sensing (ECIS) is one of such method applied for detection of cellular membrane impedance which can be correlated to cell membrane integrity. Present study intends to explore the alteration in cellular impedance along with the expression of cellular polarity molecules and cytoskeleton distributions in oral epithelial cells of habitual smokers and to correlate the outcome to that of clinically diagnosed oral leukoplakia and oral squamous cell carcinoma patients. Total 80 subjects were categorized into four study groups: nonsmoker (NS), cigarette smoker (CS), oral leukoplakia (OLPK) and oral squamous cell carcinoma (OSCC). Cytoskeleton distribution was analyzed by staining of actin filament and generation of ROS was measured using assay kit using standard protocol. Cell impedance was measured through ECIS method at different frequencies. Expression of E-cadherin and protease-activated receptor (PAR) proteins were observed through immune-fluorescence method. Distribution of actin filament is well organized in NS group however; distribution pattern was grossly varied in CS, OLPK and OSCC. Generation of ROS was low in NS which subsequently increased towards OSCC. Expressions of E-cadherin and change in cellular electrical impedance in different study groups indicated the hallmark of cancer progression from NS to OSCC. Expressions of E-cadherin, PAR protein, and cell impedance were decreased from NS to CS and farther OSCC. Generally, the oral epithelial cells exhibit apico-basal polarity however with cancer progression these cells lose their characteristic polarity distribution.

In the present work, we are offering tissue oximetry (OxyPrem) to measure hemodynamic parameters of skeletal muscles in rest and exercise. Purpose: - To elaborate the new wireless, portable, noninvasive, wearable NIRS device to measure skeletal muscle oxygenation during exercise. - To test this device on brachioradialis muscle of wrestler volunteers by using combined method of arterial occlusion (AO) and NIRS (AO+NIRS). Methods: Oxyprem NIRS device has been used together with AO test. AO test and Isometric brachioradialis muscle contraction experiments have been performed on one group of wrestler volunteers. ‘Accu- Measure’ caliper (USA) to measure skinfold thickness (SFT) has been used. Results: Elaborated device consists on power supply box, a sensor head and installed ‘Tubis’ software for data acquisition and to compute deoxyhemoglobin ([HHb), oxyhemoglobin ([O2Hb]), tissue oxygenation (StO2) and muscle tissue oxygen consumption (mVO2). Sensor head consists on four light sources with three light emitting diodes with nominal wavelengths of 760 nm, 805 nm, and 870 nm, and two detectors. AO and isometric voluntary forearm muscle contraction (IVFMC) on five healthy male subjects (23,2±0.84 in age, 0.43±0.05cm of SFT ) and four female subjects (22.0±1.0 in age and 0.24±0.04 cm SFT) has been measured. mVO2 for control group has been calculated (-0.65%/sec±0.07) for male and -0.69%/±0.19 for female subjects). Tissue oxygenation index for wrestlers in average about 75% whereas for control group StO2 =63%. Second experiment was connected with quality monitoring muscle activity during IVFMC at 10%,30% and 50% of MVC. It has been shown, that the concentration changes of HbO2 and HHb positively correlated to the contraction intensity. Conclusion: We have presented a portable multi-channel wireless NIRS device for real-time monitoring of muscle activity. The miniaturized NIRS sensor and the usage of wireless communication make the whole device have a compact-size, thus can be used in muscle monitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=skeletal%20muscle" title="skeletal muscle">skeletal muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygenation" title=" oxygenation"> oxygenation</a>, <a href="https://publications.waset.org/abstracts/search?q=instrumentation" title=" instrumentation"> instrumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=near%20infrared%20spectroscopy" title=" near infrared spectroscopy"> near infrared spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/62452/portable-noninvasive-and-wireless-near-infrared-spectroscopy-device-to-monitor-skeletal-muscle-metabolism-during-exercise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62452.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> Magnetic Single-Walled Carbon Nanotubes (SWCNTs) as Novel Theranostic Nanocarriers: Enhanced Targeting and Noninvasive MRI Tracking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Achraf%20Al%20Faraj">Achraf Al Faraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Sultana%20Shaik"> Asma Sultana Shaik</a>, <a href="https://publications.waset.org/abstracts/search?q=Baraa%20Al%20Sayed"> Baraa Al Sayed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Specific and effective targeting of drug delivery systems (DDS) to cancerous sites remains a major challenge for a better diagnostic and therapy. Recently, SWCNTs with their unique physicochemical properties and the ability to cross the cell membrane show promising in the biomedical field. The purpose of this study was first to develop a biocompatible iron oxide tagged SWCNTs as diagnostic nanoprobes to allow their noninvasive detection using MRI and their preferential targeting in a breast cancer murine model by placing an optimized flexible magnet over the tumor site. Magnetic targeting was associated to specific antibody-conjugated SWCNTs active targeting. The therapeutic efficacy of doxorubicin-conjugated SWCNTs was assessed, and the superiority of diffusion-weighted (DW-) MRI as sensitive imaging biomarker was investigated. Short Polyvinylpyrrolidone (PVP) stabilized water soluble SWCNTs were first developed, tagged with iron oxide nanoparticles and conjugated with Endoglin/CD105 monoclonal antibodies. They were then conjugated with doxorubicin drugs. SWCNTs conjugates were extensively characterized using TEM, UV-Vis spectrophotometer, dynamic light scattering (DLS) zeta potential analysis and electron spin resonance (ESR) spectroscopy. Their MR relaxivities (i.e. r1 and r2*) were measured at 4.7T and their iron content and metal impurities quantified using ICP-MS. SWCNTs biocompatibility and drug efficacy were then evaluated both in vitro and in vivo using a set of immunological assays. Luciferase enhanced bioluminescence 4T1 mouse mammary tumor cells (4T1-Luc2) were injected into the right inguinal mammary fat pad of Balb/c mice. Tumor bearing mice received either free doxorubicin (DOX) drug or SWCNTs with or without either DOX or iron oxide nanoparticles. A multi-pole 10x10mm high-energy flexible magnet was maintained over the tumor site during 2 hours post-injections and their properties and polarity were optimized to allow enhanced magnetic targeting of SWCNTs toward the primary tumor site. Tumor volume was quantified during the follow-up investigation study using a fast spin echo MRI sequence. In order to detect the homing of SWCNTs to the main tumor site, susceptibility-weighted multi-gradient echo (MGE) sequence was used to generate T2* maps. Apparent diffusion coefficient (ADC) measurements were also performed as a sensitive imaging biomarker providing early and better assessment of disease treatment. At several times post-SWCNT injection, histological analysis were performed on tumor extracts and iron-loaded SWCNT were quantified using ICP-MS in tumor sites, liver, spleen, kidneys, and lung. The optimized multi-poles magnet revealed an enhanced targeting of magnetic SWCNTs to the primary tumor site, which was found to be much higher than the active targeting achieved using antibody-conjugated SWCNTs. Iron-loading allowed their sensitive noninvasive tracking after intravenous administration using MRI. The active targeting of doxorubicin through magnetic antibody-conjugated SWCNTs nanoprobes was found to considerably decrease the primary tumor site and may have inhibited the development of metastasis in the tumor-bearing mice lung. ADC measurements in DW-MRI were found to significantly increase in a time-dependent manner after the injection of DOX-conjugated SWCNTs complexes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single-walled%20carbon%20nanotubes" title="single-walled carbon nanotubes">single-walled carbon nanotubes</a>, <a href="https://publications.waset.org/abstracts/search?q=nanomedicine" title=" nanomedicine"> nanomedicine</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20resonance%20imaging" title=" magnetic resonance imaging"> magnetic resonance imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20diagnosis%20and%20therapy" title=" cancer diagnosis and therapy"> cancer diagnosis and therapy</a> </p> <a href="https://publications.waset.org/abstracts/19881/magnetic-single-walled-carbon-nanotubes-swcnts-as-novel-theranostic-nanocarriers-enhanced-targeting-and-noninvasive-mri-tracking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19881.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">329</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">52</span> Treatment and Diagnostic Imaging Methods of Fetal Heart Function in Radiology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Farajzadeh%20Ajirlou">Mahdi Farajzadeh Ajirlou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prior evidence of normal cardiac anatomy is desirable to relieve the anxiety of cases with a family history of congenital heart disease or to offer the option of early gestation termination or close follow-up should a cardiac anomaly be proved. Fetal heart discovery plays an important part in the opinion of the fetus, and it can reflect the fetal heart function of the fetus, which is regulated by the central nervous system. Acquisition of ventricular volume and inflow data would be useful to quantify more valve regurgitation and ventricular function to determine the degree of cardiovascular concession in fetal conditions at threat for hydrops fetalis. This study discusses imaging the fetal heart with transvaginal ultrasound, Doppler ultrasound, three-dimensional ultrasound (3DUS) and four-dimensional (4D) ultrasound, spatiotemporal image correlation (STIC), glamorous resonance imaging and cardiac catheterization. Doppler ultrasound (DUS) image is a kind of real- time image with a better imaging effect on blood vessels and soft tissues. DUS imaging can observe the shape of the fetus, but it cannot show whether the fetus is hypoxic or distressed. Spatiotemporal image correlation (STIC) enables the acquisition of a volume of data concomitant with the beating heart. The automated volume accession is made possible by the array in the transducer performing a slow single reach, recording a single 3D data set conforming to numerous 2D frames one behind the other. The volume accession can be done in a stationary 3D, either online 4D (direct volume scan, live 3D ultrasound or a so-called 4D (3D/ 4D)), or either spatiotemporal image correlation-STIC (off-line 4D, which is a circular volume check-up). Fetal cardiovascular MRI would appear to be an ideal approach to the noninvasive disquisition of the impact of abnormal cardiovascular hemodynamics on antenatal brain growth and development. Still, there are practical limitations to the use of conventional MRI for fetal cardiovascular assessment, including the small size and high heart rate of the mortal fetus, the lack of conventional cardiac gating styles to attend data accession, and the implicit corruption of MRI data due to motherly respiration and unpredictable fetal movements. Fetal cardiac MRI has the implicit to complement ultrasound in detecting cardiovascular deformations and extracardiac lesions. Fetal cardiac intervention (FCI), minimally invasive catheter interventions, is a new and evolving fashion that allows for in-utero treatment of a subset of severe forms of congenital heart deficiency. In special cases, it may be possible to modify the natural history of congenital heart disorders. It's entirely possible that future generations will ‘repair’ congenital heart deficiency in utero using nanotechnologies or remote computer-guided micro-robots that work in the cellular layer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fetal" title="fetal">fetal</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20MRI" title=" cardiac MRI"> cardiac MRI</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=3D" title=" 3D"> 3D</a>, <a href="https://publications.waset.org/abstracts/search?q=4D" title=" 4D"> 4D</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20disease" title=" heart disease"> heart disease</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive" title=" invasive"> invasive</a>, <a href="https://publications.waset.org/abstracts/search?q=noninvasive" title=" noninvasive"> noninvasive</a>, <a href="https://publications.waset.org/abstracts/search?q=catheter" title=" catheter"> catheter</a> </p> <a href="https://publications.waset.org/abstracts/187696/treatment-and-diagnostic-imaging-methods-of-fetal-heart-function-in-radiology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187696.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">38</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> FISCEAPP: FIsh Skin Color Evaluation APPlication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Urban">J.

Currently, in order to compare color in animals fed on different diets, biochemical analysis, and colorimetry of fished, mildly anesthetized or dead body, are very accurate and meaningful measurements. The noninvasive method using digital images of the fish body was developed as a standalone application. This application deals with the computation burden and memory consumption of large input files, optimizing piece wise processing and analysis with the memory/computation time ratio. For the comparison of color distributions of various experiments and different color spaces (RGB, CIE L*a*b*) the comparable semi-equidistant binning of multi channels representation is introduced. It is derived from the knowledge of quantization levels and Freedman-Diaconis rule. The color calibrations and camera responsivity function were necessary part of the measurement process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=color%20distribution" title="color distribution">color distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=fish%20skin%20color" title=" fish skin color"> fish skin color</a>, <a href="https://publications.waset.org/abstracts/search?q=piecewise%20transformation" title=" piecewise transformation"> piecewise transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20to%20background%20segmentation" title=" object to background segmentation"> object to background segmentation</a> </p> <a href="https://publications.waset.org/abstracts/15406/fisceapp-fish-skin-color-evaluation-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15406.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">262</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Feature Extraction Based on Contourlet Transform and Log Gabor Filter for Detection of Ulcers in Wireless Capsule Endoscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nimisha%20Elsa%20Koshy">Nimisha Elsa Koshy</a>, <a href="https://publications.waset.org/abstracts/search?q=Varun%20P.%20Gopi"> Varun P.

Wireless Capsule Endoscopy (WCE) is a low risk, painless, noninvasive procedure for diagnosing diseases such as bleeding, polyps, ulcers, and Crohns disease within the human digestive tract, especially the small intestine that was unreachable using the traditional endoscopic methods. However, analysis of massive images of WCE detection is tedious and time consuming to physicians. Hence, researchers have developed software methods to detect these diseases automatically. Thus, the effectiveness of WCE can be improved. In this paper, a novel textural feature extraction method is proposed based on Contourlet transform and Log Gabor filter to distinguish ulcer regions from normal regions. The results show that the proposed method performs well with a high accuracy rate of 94.16% using Support Vector Machine (SVM) classifier in HSV colour space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contourlet%20transform" title="contourlet transform">contourlet transform</a>, <a href="https://publications.waset.org/abstracts/search?q=log%20gabor%20filter" title=" log gabor filter"> log gabor filter</a>, <a href="https://publications.waset.org/abstracts/search?q=ulcer" title=" ulcer"> ulcer</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20capsule%20endoscopy" title=" wireless capsule endoscopy"> wireless capsule endoscopy</a> </p> <a href="https://publications.waset.org/abstracts/17330/feature-extraction-based-on-contourlet-transform-and-log-gabor-filter-for-detection-of-ulcers-in-wireless-capsule-endoscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17330.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">540</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Co-Registered Identification and Treatment of Skin Tumor with Optical Coherence Tomography-Guided Laser Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bo-Huei%20Huang">Bo-Huei Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Hsun%20Yang"> Chih-Hsun Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Meng-Tsan%20Tsai"> Meng-Tsan Tsai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Optical coherence tomography (OCT) enables to provide advantages of noninvasive imaging, high resolution, and high imaging speed.

The sensitivity of this test is close to 90 % making it a very reliable test. However, rarely it gives a false negative result which can be explained by the phenomenon termed as “balanced ischaemia”. We present the case of a 78 year Caucasian female without any significant past cardiac history, who presents with chest pain and shortness of breath since one day. The initial ECG and cardiac enzymes were non-impressive. Few hours later, she had some substernal chest pain along with some ST segment depression in the lateral leads. Stress test comes back negative for any significant perfusion defects. However, given her typical symptoms, she underwent a cardiac catheterization which revealed significant triple vessel disease mandating her to get a bypass surgery. This unusual phenomenon of false nuclear stress test in the setting of positive ECG changes can be explained only by balanced ischemia wherein due to global myocardial ischemia, the stress test fails to reveal relative perfusion defects in the affected segments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balanced" title="balanced">balanced</a>, <a href="https://publications.waset.org/abstracts/search?q=false%20positive" title=" false positive"> false positive</a>, <a href="https://publications.waset.org/abstracts/search?q=ischemia" title=" ischemia"> ischemia</a>, <a href="https://publications.waset.org/abstracts/search?q=myocardial%20perfusion%20imaging" title=" myocardial perfusion imaging"> myocardial perfusion imaging</a> </p> <a href="https://publications.waset.org/abstracts/49756/balanced-ischemia-misleading-to-a-false-negative-myocardial-perfusion-imaging-stress-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49756.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> WO₃-SnO₂ Sensors for Selective Detection of Volatile Organic Compounds for Breath Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arpan%20Kumar%20Nayak">Arpan Kumar Nayak</a>, <a href="https://publications.waset.org/abstracts/search?q=Debabrata%20Pradhan"> Debabrata Pradhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A simple, single-step and one-pot hydrothermal method was employed to synthesize WO₃-SnO₂ mixed nanostructured metal oxides at 200°C in 12h. The SnO₂ nanoparticles were found to be uniformly decorated on the WO₃ nanoplates. Though it is widely known that noble metals such as Pt, Pd doping or decoration on metal oxides improve the sensing response and sensitivity, we varied the SnO₂ concentration in the WO₃-SnO₂ mixed oxide and demonstrated their performance in ammonia, ethanol and acetone sensing. The sensing performance of WO₃-(x)SnO₂ [x = 0.27, 0.54, 1.08] mixed nanostructured oxides was found to be not only superior to that of pristine oxides but also higher/better than that of reported noble metal-based sensors. The sensing properties (selectivity, limit of detection, response and recovery times) are measured as a function of operating temperature (150-350°C). In particular, the gas selectivity is found to be highly temperature-dependent with optimum performance obtained at 200°C, 300°C and 350°C for ammonia, ethanol, and acetone, respectively. The present results on cost effective WO₃-SnO₂ sensors can find potential application in human breath analysis by noninvasive detection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20sensing" title="gas sensing">gas sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20oxides" title=" mixed oxides"> mixed oxides</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoplates" title=" nanoplates"> nanoplates</a>, <a href="https://publications.waset.org/abstracts/search?q=ammonia" title=" ammonia"> ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=acetone" title=" acetone"> acetone</a> </p> <a href="https://publications.waset.org/abstracts/53334/wo3-sno2-sensors-for-selective-detection-of-volatile-organic-compounds-for-breath-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53334.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">240</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Quality Assurance in Cardiac Disorder Detection Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anam%20Naveed">Anam Naveed</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Andleeb"> Asma Andleeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehreen%20Sirshar"> Mehreen Sirshar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the article, Image processing techniques have been applied on cardiac images for enhancing the image quality. Two types of methodologies considers for survey, invasive techniques and non-invasive techniques. Different image processes for improvement of cardiac image quality and reduce the amount of radiation exposure for invasive techniques are explored. Different image processing algorithms for enhancing the noninvasive cardiac image qualities are described. Beside these two methodologies, third methodology has applied on live streaming of heart rate on ECG window for extracting necessary information, removing noise and enhancing quality. Sensitivity analyses have been carried out to investigate the impacts of cardiac images for diagnosis of cardiac arteries disease and how the enhancement on images will help the cardiologist to diagnoses disease. The paper evaluates strengths and weaknesses of different techniques applied for improved the image quality and draw a conclusion. Some specific limitations must be considered for whole survey, like the patient heart beat must be 70-75 beats/minute while doing the angiography, similarly patient weight and exposure radiation amount has some limitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiac%20images" title="cardiac images">cardiac images</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20angiography" title=" CT angiography"> CT angiography</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20analysis" title=" critical analysis"> critical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20radiation" title=" exposure radiation"> exposure radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20techniques" title=" invasive techniques"> invasive techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20techniques" title=" invasive techniques"> invasive techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive%20techniques" title=" non-invasive techniques"> non-invasive techniques</a> </p> <a href="https://publications.waset.org/abstracts/26171/quality-assurance-in-cardiac-disorder-detection-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26171.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Evaluation of the Role of Circulating Long Non-Coding RNA H19 as a Promising Biomarker in Plasma of Patients with Gastric Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Doaa%20Hashad">Doaa Hashad</a>, <a href="https://publications.waset.org/abstracts/search?q=Amany%20Elbanna"> Amany Elbanna</a>, <a href="https://publications.waset.org/abstracts/search?q=Abeer%20Ibrahim"> Abeer Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Gihan%20Khedr"> Gihan Khedr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: H19 is one of the long non coding RNAs (LncRNA) that is related to the progression of many diseases including cancers. This work was carried out to study the level of the long non-coding RNA; H119, in plasma of patients with gastric cancer (GC) and to assess its significance in their clinical management. Methods: A total of sixty-two participants were enrolled in the present study. The first group included thirty-two GC patients, while the second group was formed of thirty age and sex matched healthy volunteers serving as a control group. Plasma samples were used to assess H19 gene expression using real time quantitative PCR technique. Results: H19 expression was up-regulated in GC patients with positive correlation to TNM cancer stages. Conclusions: Up-regulation of H19 is closely associated with gastric cancer and correlates well with tumor staging. Convenient, efficient quantification of H19 in plasma using real time PCR technique implements its role as a potential noninvasive prognostic biomarker in gastric cancer, that predicts patient’s outcome and most importantly as a novel target in gastric cancer treatment with better performance achieved on using both CEA and H19 simultaneously. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomarker" title="biomarker">biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=gastric" title=" gastric"> gastric</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=LncRNA" title=" LncRNA"> LncRNA</a> </p> <a href="https://publications.waset.org/abstracts/45826/evaluation-of-the-role-of-circulating-long-non-coding-rna-h19-as-a-promising-biomarker-in-plasma-of-patients-with-gastric-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45826.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Detection of Intravenous Infiltration Using Impedance Parameters in Patients in a Long-Term Care Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ihn%20Sook%20Jeong">Ihn Sook Jeong</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun%20Joo%20Lee"> Eun Joo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Hyung%20Kim"> Jae Hyung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Gun%20Ho%20Kim"> Gun Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Jun%20Hwang"> Young Jun Hwang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated intravenous (IV) infiltration using bioelectrical impedance for 27 hospitalized patients in a long-term care hospital. Impedance parameters showed significant differences before and after infiltration as follows. First, the resistance (R) after infiltration significantly decreased compared to the initial resistance. This indicates that the IV solution flowing from the vein due to infiltration accumulates in the extracellular fluid (ECF). Second, the relative resistance at 50 kHz was 0.94 ± 0.07 in 9 subjects without infiltration and was 0.75 ± 0.12 in 18 subjects with infiltration. Third, the magnitude of the reactance (Xc) decreased after infiltration. This is because IV solution and blood components released from the vein tend to aggregate in the cell membrane (and acts analogously to the linear/parallel circuit), thereby increasing the capacitance (Cm) of the cell membrane and reducing the magnitude of reactance. Finally, the data points plotted in the R-Xc graph were distributed on the upper right before infiltration but on the lower left after infiltration. This indicates that the infiltration caused accumulation of fluid or blood components in the epidermal and subcutaneous tissues, resulting in reduced resistance and reactance, thereby lowering integrity of the cell membrane. Our findings suggest that bioelectrical impedance is an effective method for detection of infiltration in a noninvasive and quantitative manner. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=intravenous%20infiltration" title="intravenous infiltration">intravenous infiltration</a>, <a href="https://publications.waset.org/abstracts/search?q=impedance" title=" impedance"> impedance</a>, <a href="https://publications.waset.org/abstracts/search?q=parameters" title=" parameters"> parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=resistance" title=" resistance"> resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=reactance" title=" reactance"> reactance</a> </p> <a href="https://publications.waset.org/abstracts/96899/detection-of-intravenous-infiltration-using-impedance-parameters-in-patients-in-a-long-term-care-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96899.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">182</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Optic Nerve Sheath Measurement in Children with Head Trauma </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabiha%20Sahin">Sabiha Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kursad%20Bora%20Carman"> Kursad Bora Carman</a>, <a href="https://publications.waset.org/abstracts/search?q=Coskun%20Yarar"> Coskun Yarar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Measuring the diameter of the optic nerve sheath is a noninvasive and easy to use imaging technique to predict intracranial pressure in children and adults. The aim was to measure the diameter of the optic nerve sheath in pediatric head trauma. Methods: The study group consisted of 40 children with healthy and 40 patients with head trauma. Transorbital sonographic measurement of the optic nerve sheath diameter was performed. Conclusion: The mean diameters of the optic nerve sheath of right and left eyes were 0.408 ± 0.064 mm and 0.417 ± 0.065 mm, respectively, in the trauma group. These results were higher in patients than in control group. There was a negative correlation between optic nerve sheath diameters and Glasgow Coma Scales in patients with head trauma (p < 0.05). There was a positive correlation between optic nerve sheath diameters and positive CT findings, systolic blood pressure in patients with head trauma. The clinical status of the patients at admission, blood pH and lactate level were related to the optic nerve sheath diameter. Conclusion: Measuring the diameter of the optic nerve sheath is not an invasive technique and can be easily used to predict increased intracranial pressure and to prevent secondary brain injury. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=head%20trauma" title="head trauma">head trauma</a>, <a href="https://publications.waset.org/abstracts/search?q=intracranial%20pressure" title=" intracranial pressure"> intracranial pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=optic%20nerve" title=" optic nerve"> optic nerve</a>, <a href="https://publications.waset.org/abstracts/search?q=sonography" title=" sonography"> sonography</a> </p> <a href="https://publications.waset.org/abstracts/104676/optic-nerve-sheath-measurement-in-children-with-head-trauma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104676.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Mind Care Assistant - Companion App</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roshani%20Gusain">Roshani Gusain</a>, <a href="https://publications.waset.org/abstracts/search?q=Deep%20Sinha"> Deep Sinha</a>, <a href="https://publications.waset.org/abstracts/search?q=Karan%20Nayal"> Karan Nayal</a>, <a href="https://publications.waset.org/abstracts/search?q=Anmol%20Kumar%20Mishra"> Anmol Kumar Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=Manav%20Singh"> Manav Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research paper, we introduce "Mind Care Assistant - Companion App", which is a Flutter and Firebase-based mental health monitor. The app wants to improve and monitor the mental health of its users, it uses noninvasive ways to check for a change in their emotional state. By responding to questions, the app will provide individualized suggestions ᅳ tasks and mindfulness exercises ᅳ for users who are depressed or anxious. The app features a chat-bot that incorporates cognitive behavioural therapy (CBT) principles and combines natural language processing with machine learning to develop personalised responses. The feature of the app that makes it easy for us to choose between iOS and Android is cross-platform, which allows users from both mobile systems to experience almost no changes in their interfaces. With Firebase integration synchronized and real-time data storage, security is easily possible. The paper covers the architecture of the app, how it was developed and some important features.

The determination of individual blood pressure is a standard clinical procedure considered for cardiovascular system problems. The conventional techniques to measure blood pressure (e.g. cuff method) allows a limited number of readings for a certain period (e.g. every 5-10 minutes). Additionally, these systems cause turbulence to blood flow; impeding continuous blood pressure monitoring, especially in emergency cases or critically ill persons. In this paper, the most important statistical features in the photoplethysmogram (PPG) signals were extracted to estimate the blood pressure noninvasively. PPG signals from more than 40 subjects were measured and analyzed and 12 features were extracted. The features were fed to principal component analysis (PCA) to find the most important independent features that have the highest correlation with blood pressure. The results show that the stiffness index means and standard deviation for the beat-to-beat heart rate were the most important features. A model representing both features for Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) was obtained using a statistical regression technique. Surface fitting is used to best fit the series of data and the results show that the error value in estimating the SBP is 4.95% and in estimating the DBP is 3.99%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20pressure" title="blood pressure">blood pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=noninvasive%20optical%20system" title=" noninvasive optical system"> noninvasive optical system</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=PCA" title=" PCA"> PCA</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20monitoring" title=" continuous monitoring"> continuous monitoring</a> </p> <a href="https://publications.waset.org/abstracts/114949/monitoring-blood-pressure-using-regression-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114949.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Blood Oxygen Saturation Measurement System Using Broad-Band Light Source with LabVIEW Program</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Myoung%20Ah%20Kim">Myoung Ah Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Ho%20Sin"> Dong Ho Sin</a>, <a href="https://publications.waset.org/abstracts/search?q=Chul%20Gyu%20Song"> Chul Gyu Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blood oxygen saturation system is a well-established, noninvasive photoplethysmographic method to monitor vital signs. Conventional blood oxygen saturation measurements for the two LED light source is the ambiguity of the oxygen saturation measurement principle and the measurement results greatly influenced and heat and motion artifact. A high accuracy in order to solve these problems blood oxygen saturation measuring method has been proposed using a broadband light source that can be easily understood by the algorithm. The measurement of blood oxygen saturation based on broad-band light source has advantage of simple testing facility and easy understanding. Broadband light source based on blood oxygen saturation measuring program proposed in this paper is a combination of LabVIEW and MATLAB. Using the wavelength range of 450 nm-750 nm using a floating light absorption of oxyhemoglobin and deoxyhemoglobin to measure the blood oxygen saturation. Hand movement is to fix the probe to the motor stage in order to prevent oxygen saturation measurement that affect the sample and probe kept constant interval. Experimental results show that the proposed method noticeably increases the accuracy and saves time compared with the conventional methods. <p class="card-text"><strong>Keywords:</strong> <a
