Investigation of the fluidity of biological fluids with a PDDTBN spin probe Severcan, Feride; Acar, B; Gokalp, S (1997-06-01) The aim of this study is to ascertain whether the electron spin resonance technique using perdeutero-di-t-butyl nitroxide (PDDTBN) as a spin probe is able to monitor relative fluidity changes occurring in body fluids, such as blood and parotid saliva, according to different physiological conditions. The present study reveals that the spin probe PDDTBN is able to monitor the fluidity changes in parotid saliva related to habitual smoking, and in whole blood related to the estradiol level. The rotational corre...
Characterization of molecular-level changes due to MicroRNA-125B expression in breast cancer cells by spectroscopic and chemometric analysis techniques Şimşek Özek, Nihal; Severcan, Feride; Erson Bensan, Ayşe Elif; Department of Biology (2015) MicroRNAs (miRNAs), are 22 nucleotides long, non-coding RNAs that control gene expression post-transcriptionally by binding to their target mRNA’s 3’ UTRs (untranslated regions). Due to their crucial roles in various important regulatory processes and pathways, miRNAs have been implicated in disease mechanisms such as tumorigenesis, metastasis and drug resistance when their expression is deregulated. Moreover, the regulatory roles of these micromanagers have been demonstrated in the metabolism of cancer cel...
Investigation of age dependent contrast and T1 differences in MR images at 3.0 T: a study on MPRAGE, SPIN ECHO and FLASH protocols Aktaş, Hayriye; Gökçay, Didem; Doğru, Ewa; Department of Biomedical Engineering (2013) During healthy aging, the brain undergoes several structural changes such as brain atrophy, decreased volume of GM and WM and increase in CSF volume. These changes introduce prominent low contrast effects to the MRI images of the aging population, causing segmentation problems in the data processing pipeline. Measures of tissue characteristics such as T1, T2 provide unique and complementary information to widely used measures of brain atrophy. In this study, image quality metrics such as contrast, SNR, CNR ...
