Review ArticleOpen accessEvery word in the titleA Review of Technological Progression from Radiomics to Breathomics for Early Detection of Lung CancerFunmilayo S. Moninuola, Oluwadamilola Oshin, Emmanuel Adetiba et al.Lung Cancer (LC) is formed by an uncontrolled growth of abnormal cells in the lungs, which alters the body's metabolism. Early detection of LC is very important for a better survival rate and prognosis in patients and persons at risk of the disease. Traditional approaches to LC detection are less sensitive to cancerous cells at the early stage, are invasive … …Journal of Computer Science, Vol. 17, Issue 11 · 26 Nov 2021 · 6,257 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleClassification of Normal and Abnormal Lung CT-scan Images Using Cellular Learning AutomataNooshin Hadavi, Md Jan Nordin, Ali Shojaeipour, Mohammad Faidzul NasrudinThis paper proposes a medical pattern recognition system based on the Cellular automata (CA). CA or cellular machine is a dynamic mathematical model that consists of several similar and simple units organized by considerably simple local rules. Each cell acts as a simple computer automaton. This can lead to the implementation of the complex computations through uncomplicated methods. However, the … …Journal of Computer Science, Vol. 16, Issue 1 · 15 Jan 2020 · 7,834 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFractal Dimension for Lung Sound Classification in Multiscale SchemeAchmad Rizal, Risanuri Hidayat, Hanung Adi NugrohoLung sound is a biological signal with the information of respiratory system health. Health lung sound can be differentiated from other pathological sounds by auscultation. This difference can be objectively analyzed by a number of digital signal processing techniques. One method in analyzing the lung sound is signal complexity analysis using fractal dimension. To improve the accuracy of lung sound … …Journal of Computer Science, Vol. 14, Issue 8 · 24 Aug 2018 · 9,279 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLung Sound Classification Using Empirical Mode Decomposition and the Hjorth DescriptorAchmad Rizal, Risanuri Hidayat, Hanung Adi NugrohoLung sound is produced by the respiration process in the human respiratory tract. It contains information about the health of the respiratory organs. Lung sound is non-stationary signals and complex signals. One method for the analysis of non-stationary signals often used for the analysis of lung sounds is Empirical Mode Decomposition (EMD). EMD is used to view the Instantaneous Frequency … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 27 Jan 2017 · 8,194 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMicroscopic Study of the Lungs of Sprague-Dawley Rats from Various Ages of Postnatal and Aging PeriodsRia Margiana, Isabella Kurnia Liem, Jeanne Adiwinata PawitanPhysiological changes in postnatal and aging lung are associated with a variety of microscopic changes in the lung, especially the alveolar lung tissue, both in the interstitial and epithelial component. Interstitial tissue of the lung will increase in thickness that is supposed to be due to changes in fiber composition, particularly collagen. However, the exact changes are still under debate … …OnLine Journal of Biological Sciences, Vol. 15, Issue 2 · 13 Jun 2015 · 7,312 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Four-Directional Thresholding Approach for Lung Computed-Tomography Images by Using Similarity-Based Segmentation TechniqueSaleheh Heidari, Muhamad Taufik Abdullah, Lili Nurliana AbdullahIn automated pulmonary nodules extraction and lung disease diagnosis by image processing techniques, image segmentation is utilized as a primary and the most essential step of lung tumor analysis. But due to extensive similarity between pulmonary vessels, bronchus and arteries in lung region and the low contrast of the Computed-Tomography (CT) image the accuracy of lung tumor diagnosis is highly … …Journal of Computer Science, Vol. 11, Issue 1 · 17 Sep 2014 · 7,477 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMORINGA TEA BLOCKS ACUTE LUNG INFLAMMATION INDUCED BY SWINE CONFINEMENT DUST THROUGH A MECHANISM INVOLVING TNF-α EXPRESSION, C-JUN N-TERMINAL KINASE ACTIVATION AND NEUTROPHIL REGULATIONMykea Mcknight, Jabria Allen, Jenora T. Waterman et al.Plant based products represent a promising alternative to conventional treatments for inflammation. Moringa oleifera Lam is a tree rich in proteins, vitamins, minerals and a variety of phytochemcals with health benefits. Among the reported health benefits are antioxidant and anti-inflammatory properties. The purpose of this study was to investigate whether tea brewed from dried Moringa leaves would abrogate inflammation in … …American Journal of Immunology, Vol. 10, Issue 2 · 8 May 2014 · 11,600 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NOVEL APPROACH TO DETECT FISSURES IN LUNG CT IMAGES USING MARKER-BASED WATERSHED TRANSFORMATIONK. Devaki, V. Murali BhaskaranDetection and segmentation of fissures is useful in the clinical interpretation of CT lung images to diagnose the presence of pathologies in the human lungs. A new automated method based on marker-based watershed transformation has been proposed to segment the fissures considering its unique structure as a long connected component. Marker based watershed transformation is applied and morphological operations are … …Journal of Computer Science, Vol. 10, Issue 6 · 25 Jan 2014 · 6,425 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleToxicity of Zinc Oxide Nanoparticles in Lung Tissue After Repeated Oral AdministrationAtaollah Shokouhian, Saman Soheili, Saeed Moradhaseli et al.Pathological experiments should be considered following oral administration of ZnO. Effect of different doses of ZnO nanoparticle on LDH in oral method showed significant differences in control group (p<0.05) at high dose. Levels of IgG, TNF-α and IL-6 also elevated after administration of ZnO. The level of GSH decreased significantly. Lung damages included hyperemia and bleeding, atelectasis, light emphysema, pribronchiolitis, … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 4 · 21 Oct 2013 · 7,703 accessesView PDFCite
