OBJECTIVES The aim of this study was to assess the effect of 30% hydrogen peroxide on the microleakage of class V cavities restored with either a silorane-based composite or two methacrylate-based composites. MATERIALS AND METHODS A total of 96 standard class V cavities (1.5 × 2 × 3 mm) were prepared on the buccal surface of sound extracted human premolars with both enamel and dentin margins ...

Results: The median tumor basal diameter was 5.0 mm and thickness was 1.5 mm. Nevus growth into melanoma occurred in 2%, 9%, and 13% of eyes at 1, 5, and 10 years, respectively. Factors predictive of growth into melanoma by multivariable analysis included tumor thickness greater than 2 mm (P .001), subretinal fluid (P = .002), symptoms (P = .002), orange pigment (P .001), tumor margin within 3 ...

Objective To determine the correlation of different tumor-size cutoffs with prognostic factors and survival outcomes to provide a reference for the modification of the T-stage classification in the DeOliveira staging system for hilar cholangiocarcinoma (HCCA). Materials and Methods We retrospectively analyzed 216 patients who underwent curative surgery for HCCA (mean tumor diameter, 2.8 cm) b...

The paper deals with the design of the robust PID controller for real uncertain Coupled-Tank process in the frequency domain. Only the first independent tank is considered (single-input single-output system). Robust controller is designed in two ways. The first approach is performed with the Edge Theorem and the Neimark’s D -partition method for the affine model and the second one is performed ...

We have recently proposed an extension of ADABOOST to regression that uses the median of the base regressors as the final regressor. In this paper we extend theoretical results obtained for ADABOOST to median boosting and to its localized variant. First, we extend recent results on efficient margin maximizing to show that the algorithm can converge to the maximum achievable margin within a pres...

The local recurrence rate of phyllodes tumors of the breast varies widely among different subtypes, and distant metastasis is associated with poor survival. This study aimed to identify factors that are predictive of local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and overall survival (OS) in patients with phyllodes tumors of the breast. Clinical data of all pati...

OBJECTIVE To determine features that are predictive of growth of choroidal nevi into melanoma. METHODS This was a retrospective medical record review of 2514 consecutive eyes; Kaplan-Meier estimates and Cox regression analyses were used. RESULTS The median tumor basal diameter was 5.0 mm and thickness was 1.5 mm. Nevus growth into melanoma occurred in 2%, 9%, and 13% of eyes at 1, 5, and 10...

Background and aims. Furcally-involved teeth present unique challenges to the success of periodontal therapy and influence treatment outcomes. This study aimed to assess to compare use of ADM and connective tissue membrane in class II furcation defect regeneration. Materials and methods. 10 patient with 2 bilaterally class II furcation defects in first and/or second maxilla or man-dibular molar...

To investigate the impact of different surgical margin and recurrence-free survival in patients with hepatocellular carcinoma (HCC). The data of 601 patients who underwent curative hepatectomy for HCC between January 1997 and December 2009 were analyzed. Milan group and exceeding Milan group were divided according to the Milan Criteria. Each of them was divided into 3 groups: group A (surgical ...

Received January 13, 2007; accepted March 4, 2007. OBJECTIVE To investigate the factors that can accurately predict the prognosis for patients with FIGO stage-IB cervical squamous cell carcinoma treated with radical surgery. METHODS A retrospective analysis of clinical data from 174 cases of FIGO Stage-IB cervical squamous cell carcinoma treated in our institute was conducted. RESULTS The 5-yea...
