Potassium iodide potentiated photodynamic inactivation of enterococcus faecalis using toluidine blue: comparative analysis, photothermal effect, and post - treatment biofilm formation study

Ghaffari, Sahand A. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2018., 2018.)

Antimicrobial Photodynamic Inactivation (aPDI) has recently gained interest as an alternative modality to ﬁght pathogenic entities. Its eﬀect can also be further enhanced by using certain inorganic salts. Here, the Potassium ...
Magnetic resonance imaging based differential diagnosis and prognoasis of mild cognitive impairment in parkinson's disease using machine learning

Genç, Ozan. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2018., 2018.)

Parkinson’s disease mild cognitive impairment (PD-MCI), which is one of the major risk factors for dementia, is present in 26.7% of PD patients. In this study, we classiﬁed PD-MCI, cognitively normal Parkinson’s disease ...
Layer specific distribution of muscarinic receptor M2 in the the sensorimotor areas of rat brain

Yusufoğlulları, Sedef. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2018., 2018.)
