This study was conducted to differentiate malignant pleural mesothelioma (MPM) from lung cancer (LC) and benign pleural effusion (BPE) from pleural fluids using the diagnostic power of Fourier transform-infrared spectroscopy with attenuated total reflectance mode coupled with chemometrics. Infrared spectra of MPM (n = 24), LC (n = 20), and BPE (n = 25) were collected, and hierarchical cluster analysis (HCA) and principal component analysis (PCA) were applied to their spectra. HCA results indicated that MPM was differentiated from LC with 100% sensitivity and 100% specificity and from BPE, with 100% sensitivity and 88% specificity, which were also confirmed by PCA score plots. PCA loading plots indicated that these separations originated mainly from lipids, proteins, and nucleic acids-related spectral bands. There was significantly higher lipid, protein, nucleic acid, and glucose contents in the MPM and LC. However, the significant changes in triglyceride and cholesterol ester content, protein and nucleic acid structure, a lower membrane fluidity, and higher membrane order were only observed in the MPM. To check the classification success of some test samples/each group, soft independent modeling of class analogies was performed and 96.2% overall classification success was obtained. This approach can provide a rapid and inexpensive methodology for the efficient differentiation of MPM from other pleural effusions.

Rapid diagnosis of malignant pleural mesothelioma and its discrimination from lung cancer and benign exudative effusions using blood serum Yonar, Dilek; Severcan, Mete; Gurbanov, Rafig; Sandal, Abdulsamet; Yilmaz, Ulku; Emri, Salih; Severcan, Feride (2022-10-01) © 2022Malignant pleural mesothelioma (MPM), an aggressive cancer associated with exposure to fibrous minerals, can only be diagnosed in the advanced stage because its early symptoms are also connected with other respiratory diseases. Hence, understanding the molecular mechanism and the discrimination of MPM from other lung diseases at an early stage is important to apply effective treatment strategies and for the increase in survival rate. This study aims to develop a new approach for characterization and d...
Differentiation of Chronic and Aggressive Periodontitis by FTIR Spectroscopy Ozek, N. Simsek; Zeller, I.; Renaud, D. E.; Gumus, P.; NİZAM, NEJAT; Severcan, Feride; BUDUNELİ, NURCAN GÜLSÜM; Scott, D. A. (2016-12-01) Without longitudinal clinical data, it is difficult to differentiate some cases of chronic periodontitis (CP) and aggressive periodontitis (AgP). Furthermore, both forms of disease are exacerbated by tobacco use. Therefore, this cross-sectional study was planned, primarily, to determine the ability of Fourier-transform infrared (FTIR) spectroscopy to distinguish CP and AgP patients by analysis of human saliva samples and, secondarily, to assess the potential confounding influence of smoking on discriminatin...
Determination of binary pesticide mixtures by an acetylcholinesterase-choline oxidase biosensor Kok, FN; Hasırcı, Vasıf Nejat (2004-02-15) In this study, acetylcholinesterase (AChE) and choline oxidase (ChO) were co-immobilized on poly (2-hydroxyethyl methacrylate) (pHEMA) membranes to construct a biosensor for the detection of anti-cholinesterase compounds. pHEMA membranes were prepared with the addition of SnCl4 to achieve the desired porosity. Immobilization of the enzymes was done by surface attachment via epichlorohydrin (Epi) and Cibacron Blue F3G-A (CB) activation. Enzyme immobilized membrane was used in the detection of anti-cholineste...
Classification of lung nodules in CT images using convolutional neural networks Polat, Görkem; Serinağaoğlu Doğrusöz, Yeşim; Halıcı, Uğur; Department of Electrical and Electronics Engineering (2018) Recent studies have shown that lung cancer screening using annual low-dose computed tomography (CT) reduces lung cancer mortality by 20% compared to traditional chest radiography. Therefore, CT lung screening has started to be used widely all across the world. However, analyzing these images is a serious burden for radiologists. The number of slices in a CT scan can be up to 600. Therefore, computeraided-detection (CAD) systems are very important for faster and more accurate assessment of the data. In this ...
Characterization and promoter identification of metastasis associated protein 1 in human colorectal carcinoma cell lines Tunçay Çağatay, Seda; Erson Bensan, Ayşe Elif; Department of Biology (2014) Metastasis associated protein 1 (MTA1) is a member of the nuclear remodeling and histone deacetylase (NuRD) complex, which is known to repress the expression of several tumor suppressor genes and has been widely linked to tumor metastasis. 15-lipoxygenase-1 (15-LOX-1) is a lipid metabolizing enzyme that has tumor suppressive properties and is silenced by the NuRD complex in colorectal cancer (CRC). We have previously shown that reexpression of 15-LOX-1 inhibited metastasis in CRC, inhibited the inflammatory...
