Removal of bacterial biofilm from the root canal system is essential for management endodontic disease. Here we evaluated antibacterial effect N-acetylcysteine (NAC), a potent antioxidant and mucolytic agent, against mature multispecies biofilms consisting Actinomyces naeslundii, Lactobacillus salivarius, Streptococcus mutans Enterococcus faecalis on sterile human dentin blocks. The were exposed to NAC (25, 50 100mg/mL), saturated calcium hydroxide or 2% chlorhexidine solution 7 days, then...

Several studies have demonstrated that human umbilical cord blood-derived mesenchymal stem cells can promote neural regeneration following brain injury. However, the therapeutic effects of in guiding peripheral nerve remain poorly understood. This study was designed to investigate on using a rat sciatic crush injury model. Human (1 × 10(6)) or PBS control were injected into crush-injured segment nerve. Four weeks after cell injection, brain-derived neurotrophic factor and tyrosine kinase...

The drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is a severe adverse drug-induced which includes skin eruption, fever, hematologic abnormalities (eosinophilia or atypical lymphocytes) internal organ involvement. most frequently reported was anticonvulsants. diagnosis of DRESS challenging because the pattern cutaneous eruption types organs involved are various. treatments for culprit withdrawal corticosteroids. Here we report 71-year-old man hepatic renal involvement...

Abstract Titanium (Ti) screw has excellent mechanical property, and osseointegration capacity. However, they require surgery for removal. In contrast, polymer screws are resorbable, but have poor properties. this research, magnesium alloy (WE43: Mg‐Y‐Nd‐Zr) that advantages of titanium were manufactured. addition, to increase biocompatibility control degradation rate, the Mg was coated with hydroxyapatite (HA). Torsion test corrosion performed in vitro . For clinical, radiological...

Abstract Objectives This study evaluated implant stability and clinical outcomes obtained with magnesium‐incorporated oxidised implants ( M g titanate) compared them to those blasted (blasted titanate). Patients methods Mg titanate was manufactured using the microarc oxidation MAO ) process. To obtain titanate, process performed after blasting T i O 2 particles. The 15‐month, randomised, double ‐blind trial conducted on 54 in 40 patients 27 18 subjects; 22 subjects), whom 4.0 mm × 10 were...

Abstract Background To evaluate the facial asymmetry, three-dimensional computed tomography (3D-CT) has been used widely. This study proposed a method to quantify asymmetry based on 3D-CT. Methods The normal standard group consisted of twenty-five male subjects who had balanced face and occlusion. Five anatomical landmarks were selected as reference points ten measurement asymmetry. formula index was designed by using distances between landmarks. value specific landmark indicated zero when...

Objectives This study was conducted in order to assess the efficacy of 1st generation cephalosporin as use a single-dose preoperative prophylactic antibiotic for surgical wound infections resulting from intra-oral bone grafting procedures. Materials and Methods A total 23 patients who were undergo graft procedures participated this study. After randomization, 2 grams orally administered both experimental placebo groups one hour prior surgery double-blind fashion. Post-operatively, group (12...

Objectives Although nerve growth factor (NGF) could promote the functional regeneration of an injured peripheral nerve, it is very difficult for NGF to sustain therapeutic dose in defect due its short half-life. In this study, we loaded NGF-bound heparin-conjugated fibrin (HCF) gel NGF-delivering implants and analyzed time-dependent release bioactivity evaluate clinical effectiveness. Materials Methods solution was made 1.0 mg mL phosphate buffered saline (PBS). Experimental group A...

Objective. This study evaluated the potential of interleukin 12 receptor beta 2 and tumor necrosis factor superfamily member 8 as diagnostic biomarkers oral lichen planus (OLP). Materials methods. The mRNA expression IL12RB2 TNFRSF8 in FFPE OLP samples (OLP group, n = 38) were investigated with quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) analysis compared to those chronic non-specific mucositis (Non-OLP 25) normal mucosa (Normal 18). Predictive modeling was...

Cadmium (Cd) is a nephrotoxic heavy metal. Several signal transduction pathways have been reported to be associated with Cd toxicity. GPRC5B member of the family G-protein-coupled receptors, which recognize various ligands and can transmit signals from cell surface into interior. We examined involvement in toxicity HK-2 human proximal tubular cells. Herein, we found that significantly reduced gene expression Moreover, knockdown by siRNA transfection strengthened Our findings suggest...

Purpose: Oncoplastic breast conserving surgery is a new concept in cancer surgery. We performed immediate latissimus dorsi flap reconstruction after (BCS) to get an adequate resection margin and good cosmetic results. The aim of this study evaluate the effect BCS. Methods: From January December, 2007, we BCS dosi myocutaneous for 44 patients. evaluated status post operative margin, complications results were with paying particular attention symmetry breasts, shape, location nipple...

Compared to acupuncture, the pulsed magnetic field (PMF) stimulus is a useful tool for treatment of many physical conditions and health maintenance due its advantages as noninvasive nontoxic medical treatment. The purpose this study was investigate effect PMF direction at PC9 on alpha activity electroencephalogram (EEG) vascular aging calculated from photoplethysmograph (PPG). It can be concluded that affects increase EEG PPG, indicating stiffness sclerosis level blood vessels weakly...

The authors propose an enhanced location management scheme for the register (LR) in wireless ATM networks. main distribution is use of at most two active LRs and dynamic scope-limiting parameter S depending on communication-to-computation cost ratio (CCR) as well call-to-move (CMR). As a result, proposed can reduce compared with original LR different CCR value CMR value.
