OBJECTIVES Falls are a major problem in the elderly. Age-related degeneration of the human balance system increases the risk of falls. Kyphosis is a common condition of curvature of the upper spine in the elderly and its development occurs through degenerative change. However, relatively little is known about the effect of kyphotic changes on balance in the(More)
Acute toxicity and oxidative stress caused by exposure of titanium dioxide nanoparticles (TiO2-NPs) in juvenile common carp (Cyprinus carpio) were investigated. TiO2-NPs solution was prepared using deionized water and dispersed by sonication. Juvenile carp were exposed to different concentrations (5, 10, 20, 40, and 80 mg/L) of TiO2-NPs. TiO2-NP(More)
OBJECTIVE To evaluate the effectiveness of sucralfate in influencing throat pain, otalgia, analgesic requirement, bleeding, mucosal recovery, and incidence of postoperative bleeding in patients undergoing uvulopalatopharyngoplasty. DESIGN A prospective double-blind randomized study. SETTING University-affiliated tertiary referral hospital. (More)
BACKGROUND Epithelial cells can be called the first line of a defense barrier to microorganisms by the innate immune system. The antimicrobial peptides are the major participants of this system. Cathelicidins are a family of peptides thought to provide an innate defensive barrier against a variety of potential microbial pathogens. OBJECTIVES To evaluate(More)
OBJECTIVE The head shake sensory organization test (HS-SOT) is an expansion of the sensory organization test (SOT), which evaluates impairment of the patient's ability to apply vestibular input while actively moving the head. HS-SOTs has been proposed to increase the sensitivity of SOTs. The purpose of this study was to investigate the value of HS-SOTs in a(More)
Dentigerous cyst is one of the most prevalent types of odontogenic cysts and is associated with crown of an unerupted or developing tooth. Dentigerous cysts are usually asymptomatic, so facial swelling may be the first clinical sign of a dentigerous cyst. A dentigerous cyst forming a septal abscess is uncommon. We report a case of dentigerous cyst(More)
OBJECTIVE The aim of this study was to evaluate the histologic change of middle ear mucosa and the expression levels of epithelial sodium channel (ENaC) subunits and mucin production genes, after the injection of urban particulate matter (UPM) into the middle ear cavity of rats. METHODS Fifty pathogen-free, male Sprague Dawley rats were assigned to the(More)
OBJECTIVE Metformin is a well-known anti-diabetic agent, but its mechanism is unclear. Recently, many reports have described the anti-inflammatory effects of metformin on various cell types, including human vascular smooth muscle cells and endothelial cells. This study was designed to investigate the anti-inflammatory effect of metformin on(More)
OBJECTIVE The epithelial cells of the middle ear and Eustachian tube must maintain an adequate mucosal defense system against various antigenic stimuli. Since toll-like receptors (TLRs) are known to play a critical role in mucosal defense, we investigated their expression in the mucosa of the tubotympanum, nasopharynx, and oral cavity of the rat. METHOD(More)
CONCLUSIONS The results suggest that the anti-inflammatory effect of caffeic acid phenethyl ester (CAPE) is due to its inhibition of tumor necrosis factor (TNF)-alpha expression and interleukin (IL)-8 production. The anti-inflammatory effect of CAPE is possibly through the inhibition of nuclear factor (NF)-kappaB via the suppression of(More)
