The aim of this study is to evaluate the effects of low-level laser therapy (LLLT) on (1) the velocity of orthodontic tooth movement and (2) the nitric oxide levels in gingival crevicular fluid (GCF) during orthodontic treatment. The sample consisted of 20 patients (14 girls, six boys) whose maxillary first premolars were extracted and canines distalized. A(More)
Butyrylcholinesterase (BChE, EC 3.1.1.8) has been purified about 6600-fold from human serum with a procedure including ammonium sulfate fractionation (55-70%) with acid step at pH 4.5 and procainamide-Sepharose 4B affinity chromatography. The purified enzyme exhibited negative cooperativity with respect to butyrylthiocholine (BTCh) binding at pH 7.5. Ks was(More)
BACKGROUND This study was designed to evaluate the possible protective effects of low-dose methotrexate in the spinal cord injury (SCI) in rats. METHODS Thirty-seven Wistar albino rats were used in the present study. Except for the animals of the Sham group, all animals were divided into two main groups, which were used in acute and subacute stage(More)
BACKGROUND/AIM The survival of autologous fat graft tissue is dependent on various factors such as vascularization and inflammation. The aim of the present study was to evaluate the possible beneficial effects of low-dose methotrexate (LD-MTX) on fat graft volume and survival. MATERIALS AND METHODS A total of 13 male Wistar albino rats were divided into(More)
Statins possess a wide variety of pleiotropic properties that are independent of their lipid-lowering abilities such as attenuating inflammation, oxidative stress, coagulation, platelet aggregation and stimulating bone formation. The aim of the study is to evaluate the effect of statins on clinical periodontal parameters and gingival crevicular fluid (GCF)(More)
AIM Although polyethylene glycol (PEG) is a neutral, biocompatible hydrophilic polymer recognized for its lack of interaction with biological barrier, its neurotoxicity has not been clearly identified in neurosurgery. This study is constructed to evaluate the possible neurotoxicity of a PEG hydrogel dural sealant. MATERIAL AND METHODS(More)
BACKGROUND The survival of autologous fat graft tissue is dependent on various factors, such as vascularization and inflammation. OBJECTIVE This study aims to evaluate the possible beneficial effects of dimethylsulfoxide (DMSO) on fat graft volume and survival. METHODS Eighteen male Wistar albino rats were divided randomly into three groups. An(More)
OBJECTIVE Oxidative metabolism is impaired in several medical conditions including psychiatric disorders, and this imbalance may be involved in the etiology of these diseases. The present study evaluated oxidative balance in pediatric and adolescent patients with attention deficit hyperactivity disorder (ADHD). METHODS The study included 48 children and(More)
