Assessment of oxidative stress effects in serum determined by FT-IR spectroscopy in cholangiocarcinoma patients
Bulut, Huri; Tarhan, Nevzat; Buyuk, Melek; Serin, Kurşat Rahmi; Ulukaya, Engin; Depciuch, Joanna; Parlinska-Wojtan, Magdalena; Guleken, Zozan (AMG Transcend Association, 2023)Cholangiocarcinoma (CCA) is a heterogeneous malignant tumor containing intrahepatic and extrahepatic bile ducts and gallbladder carcinoma. Mostly diagnosed at an advanced stage with a <5% cure chance. Early-stage diagnosis ... -
Assessment of structural protein expression by FTIR and biochemical assays as biomarkers of metabolites response in gastric and colon cancer
Guleken, Zozan; Bulut, Huri; Gültekin, Güldal İnal; Arikan, Soykan; Yaylim, Ilhan; Hakan, Mehmet Tolgahan; Sönmez, Dilara; Tarhan, Nevzat K.; Depciuch, Joanna (Elsevier B.V., 2021)Colon and gastric cancers are the widespread benign types of cancers which are synchronous and metachronous neoplasms. In terms of the progression and progress of the disease, metabolic processes and differentiation in ... -
Assessment of the effect of endocrine abnormalities on biomacromolecules and lipids by FT-IR and biochemical assays as biomarker of metabolites in early Polycystic ovary syndrome women
Guleken, Zozan; Bulut, Huri; Bulut, Berk; Depciuch, Joanna (Elsevier, 2021)Polycystic ovary syndrome (PCOS) is a common endocrinopathy associated with metabolic disturbances.Both in the development and improvement of the disease, the structure of phospholipids and proteinsin the blood serum plays ... -
Blood serum lipid profiling may improve the management of recurrent miscarriage: a combination of machine learning of mid-infrared spectra and biochemical assays
Guleken, Zozan; Bahat, Pinar Yalcin; Toto, Omer Faruk; Bulut, Huri; Jakubczyk, Pawel; Cebulski, Jozef; Paja, Wieslaw; Pancerz, Krzysztof; Wosiak, Agnieszka; Depciuch, Joanna (SPRINGER HEIDELBERG, 2022)The present article is focused on developing and validating an efficient, credible, minimally invasive technique based on spectral signatures of blood samples of women with recurrent miscarriage vs. those of healthy ... -
Characterization of Covid-19 infected pregnant women sera using laboratory indexes, vibrational spectroscopy, and machine learning classifications
Guleken, Zozan; Jakubczyk, Paweł; Paja, W.; Krzysztof, Pancerz; Bulut, Huri; Öten, Esra; Depciuch, Joanna; Tarhan, Nevzat K. (Elsevier B.V., 2022)Herein, we show differences in blood serum of asymptomatic and symptomatic pregnant women infected with COVID-19 and correlate them with laboratory indexes, ATR FTIR and multivariate machine learning methods. We collected ... -
The cognitive dynamics of small-sooner over large-later preferences during temporal discounting task through event-related oscillations (EROs)
Guleken, Zozan; Sutcubasi, Bernis; Metin, Baris (Elsevier Science, 2021)Event-related oscillations (ERO) may provide a useful tool for the identification of cognitive processes during economic decisions. In the present study, we investigate peak-to-peak amplitude of task event-related oscillations ... -
Diagnosis of endometriosis using endometrioma volume and vibrational spectroscopy with multivariate methods as a noninvasive method
Guleken, Zozan; Bulut, Huri; Depciuch, Joanna; Tarhan, Nevzat (Elsevier Science, 2022)Endometriomas are typically an advanced form of endometriosis that leads to the formation of scar tissue, adhesions, and an inflammatory reaction. There is no certain serum marker for the diagnosis of endometriosis. This ... -
Differential of cholangiocarcinoma disease using Raman spectroscopy combined with multivariate analysis
Depciuch, Joanna; Parlinska-Wojtan, Magdalena; Serin, Kursat Rahmi; Bulut, Huri; Ulukaya, Engin; Tarhan, Nevzat; Guleken, Zozan (2022)Cholangiocarcinoma (CCA) is a type of cancer, which 5-year survival is lower than 20 %, and which is detected mostly in advanced stage of the disease. Unfortunately, there are no diagnostic tools, which could show changes ... -
Investigation of the effects of transcranial direct current stimulation and neurofeedback by continuous performance test
Guleken, Zozan; Eskikurt, Gokcer; Karamursel, Sacit (Elsevier Ireland Ltd, 2020)Transcranial direct current stimulation (tDCS) is a noninvasive neuromodulation technique based on weak direct current stimulation through the scalp. Neurofeedback (NFB) is a learning strategy that may help alter to brain ... -
Spectrochemical and biochemical assay comparison study of the healing effect of the aloe vera and hypericum perforatum loaded nanofiber dressings on diabetic wound
Guleken, Zozan; Depciuch, Joanna; Ege, Hasan; Ilbay, Gul; Kalkandelen, Cevriye; Ozbeyli, Dilek; Bulut, Huri; Tarhan, Nevzat; Erdem Kuruca, Serap (Elsevier, 2021)Diabetic wounds have a slow healing process and easy to be infected. In addition to current drug treatments, supportive approaches are needed for diabetic wound treatment. In this study, we aimed to load Aloe Vera (AV) and ...
