In this study, the coronal and sagittal heights of the pituitary glands were measured by magnetic resonance imaging (MRI) technique in 201 individuals. There was no sellar or parasellar region pathology in the study group. The data were evaluated according to age and sex groups. In all cases the coronal and sagittal heights of the pituitary glands were… (More)
Five cases are described where the first web space of the hand received arteries only from the superficial palmar arch. None of these branches was large enough to deserve the name "princeps pollicis artery". These variations must be taken into account during surgical dissections of the hand.
Distraction was previously studied within each dimension separately, i.e., physical, cognitive and visual. However real-world activities usually involve multiple distraction dimensions in terms of brain resources that might conflict with the driving task. This brings difficulties for classifying dimension/type of distraction even for human experts. On the… (More)
Vigilance decrement happens in prolonged and monotonous tasks such as driving, therefore efficient estimation of vigilance using machine learning becomes a growing research field in road safety. However, the ground truth of vigilance level is often unknown. To address the estimation of brain states with unknown ground truth, we proposed an unsupervised… (More)
AIM Piriformis syndrome is a rare neuromuscular disorder that occurs when the piriformis muscle compresses or irritates the sciatic nerve. The treatment of piriformis syndrome includes injections into the piriformis muscle around the sciatic nerve. These invasive approaches have been used with various techniques to increase the safety of the procedure.… (More)
In this study, the myelinated axons of parts of the corpus callosums of young and old rats were examined under the electron microscope and a grading system was performed for quantitating the ultrastructural pathological changes of these axons. Except the old splenium group, the only ultrastructural pathological change, observed in the myelinated axons was… (More)
