OBJECTIVES The mucociliary transport system is a major defense mechanism of the respiratory tract. The performance of mucous transportation in the nasal cavity can be represented by a ciliary beating frequency (CBF). This study proposes a novel method to measure CBF by using optical flow. METHODS To obtain objective estimates of CBF from video images, an(More)
BACKGROUND The lack of sufficient specificity and sensitivity among conventional cancer biomarkers, such as prostate specific antigen (PSA) for prostate cancer has been widely recognized after several decades of clinical implications. Autoantibodies (autoAb) among others are being extensively investigated as potential substitute markers, but remain elusive.(More)
OBJECTIVE α-Melanocyte-stimulating hormone (α-MSH) and agouti-related peptide (AgRP) control energy homeostasis by their opposing actions on melanocortin receptors (MC3/4R) in the hypothalamus. We previously reported that thyroid transcription factor-1 (TTF-1) controls feeding behavior in the hypothalamus. This study aims to identify the function of TTF-1(More)
Major orbital complications after the endoscopic sinus surgeries are rare and of these, optic nerve injury is one of the most serious. This study was to undertaken to analyze 3 cases of optic nerve injury after endoscopic sinus surgery. The three cases included one patient with a loss of visual acuity and visual field defect, and two patients with total(More)
BACKGROUND Even though the olfactory function usually is improved or unchanged after ethmoidectomy, some patients complain of olfactory disturbance, which may be caused by direct injury to the olfactory nerves. However, the detailed anatomic pathway of the olfactory nerves that leave the olfactory mucosa and after going through the cribriform plate insert(More)
PURPOSE To evaluate the efficacy and safety of once-daily ciclesonide in comparison to both levocetirizine alone, and a ciclesonide/levocetirizine combination in patients with seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR). METHODS Subjects exhibiting moderate to severe allergic rhinitis for longer than 1 year were randomized in an(More)
OBJECTIVE To investigate the long-term outcomes of cardiac rehabilitation (CR) on exercise capacity in diabetic (DM) and non-diabetic (non-DM) patients with myocardial infarction (MI). METHODS Of the MI patients who received hospital-based CR from February 2012 to January 2014, we retrospectively reviewed the medical records of the patients who continued(More)
AIMS/INTRODUCTION The interactive effects of resistance training and dietary protein on hormonal responses in adults are not clear and remain controversial. We tested the effect of an isocaloric high-protein diet on body composition, ghrelin, and metabolic and hormonal parameters during a 12-week resistance training program in untrained healthy young men.(More)
Large area thin films of few-layered unfunctionalized graphene platelets are developed with fine control over the thickness. The thin films are obtained by a Langmuir-Blodgett assembly at the interface of graphene solution in N-methyl-2-pyrrolidone (NMP) and water, and their optoelectronic properties and conduction mechanism are investigated in relation to(More)
