This work aims to synthesize novel thermoresponsive hydrogels from renewable resources, bacterial cellulose (BC), and castor oil (CO), and to investigate the effect of CO on physical and thermal behaviors of BC/Poly(N‐isopropylacrylamide) (PNIPAM) hydrogels. The structural properties of the hydrogels are analyzed by Fourier‐transform infrared (FTIR) spectroscopy. Differential scanning calorimeter...
In this study the photoplethysmography (PPG) signals while mental workload during resting state and physical fatigue and tiredness are investigated. The aim is to examine the relationship between restricted physical fatigue and mental workload, and effects of mental workload on PPG during pre- and post-exercise accompanied with mathematical exercise besides physiological and electrophysiological measurements...
Thermoresponsive hydrogels have great potential in biomedical applications such as drug delivery systems and tissue engineering. Synthesis of hydrogels from renewable resources attracts attention day by day. In this study special type of thermoresponsive hydrogels were synthesized. These hydrogels are cross-linked hydrophilic polymers containing some biocompatible moieties which are derived from plant...
In this study, the unsupervised clustering method namely K-means algorithm is applied for identifying the multiple sclerosis (MS) lesions in magnetic resonance (MR) images automatically. MS lesion detection is essential for diagnosing the disease and monitoring its progression. The automated method aims to eliminate user-dependent classification errors and to improve computational capacity in detecting...
In this study, differences on the replies of autonomic and central nervous system based on physical performance are aimed to be examined during transition from resting state brain network to mental performance demanding states. The effect of mental workload generated by mental arithmetic task after controlled physical performance between amateur sportsmen and sedanters is investigated in terms of...
Thermoresponsive hydrogels are crosslinked hydrophilic polymers that absorb water and change their conformations depending on physiological conditions. As they swell/shrink according to environmental conditions, they are designed as stimuli responsive drug delivery/controlled release systems. Quercetin, with proven beneficial impact on health, is one of the phenolic flavonoids and the most potent...
