OBJECTIVES Bulk-fill composite materials are being developed for preparation depths of up to 4 mm in an effort to simplify and improve the placement of direct composite posterior restorations. The aim of our study was to compare shear-bond strength of bulk-fill and conventional posterior composite resins. MATERIALS AND METHODS In this study, 60 caries free extracted human molars were used and...

The flotation spectrophotometric method for determination of platinum (Pt) with isochromatic dye ion-pair was described. [(2R6G) (PtBr6)⋅3(R6G⋅Br)] was resolved and Rhodamine 6G (R6G) was entered into aqueous phase when pH = 5.5 HAc-NaAc buffer solution was added to the [(2R6G) (PtBr6)⋅3(R6G⋅Br)] in medium of toluene. And then R6G·TBF was flotated by tetrabromofluorescein (TBF) with toluene. Th...

Intentional forgetting benefits memory by removing no longer needed information and promoting processing of more relevant materials. This study sought to understand how the behavioural and neurophysiological representation of intentional forgetting would be impacted by emotion. We took a novel approach by examining the unique contribution of both valence and arousal on emotional directed forget...

In the present study a music therapeutic intervention according to the 'Heidelberg Model' was evaluated as a complementary treatment option for patients with acute tinnitus whom medical treatment only brought minimal or no improvement. The central question was if music therapy in an early phase of tinnitus was able to reduce tinnitus symptoms and to prevent them from becoming chronical. 23 pati...

The period of event-free survival (EFS) within the same histopathological glioma grades may have high variability, mainly without a known cause. The purpose of this study was to reveal the prognostic value of quantified tumor blood flow (TBF) values obtained by arterial spin labeling (ASL) for EFS in patients with histopathologically proven astrocytomas independent of WHO (World Health Organiza...

Background: Body mass index (BMI) is commonly used as a proxy to determine excess adiposity, though this may underestimate fat (FM) in individuals of South Asian (SA) heritage. SA tend have greater central adiposity than white people, which associated with higher risk cardiometabolic disease. In cross-sectional study, we aimed the differences total and regional FM us...

BACKGROUND In non-small cell lung cancer (NSCLC) patients off erlotinib therapy, positron emission tomography (PET) using [(11)C]erlotinib distinguished epidermal growth factor receptor (EGFR) mutations from wild-type EGFR. However, tumor uptake of [(11)C]erlotinib during erlotinib therapy is unknown. Therefore, the aims of this study were to evaluate tumor [(11)C]erlotinib uptake in NSCLC pati...

Effect of retained austenite characteristics on V-bending in ultrahigh-strength TRIP-aided steel sheets with bainitic ferrite matrix (TBF steel) was investigated for automotive applications. tests were performed a servohydraulic testing machine at processing speed 1 mm/min using 88-degree V-punch (2.0 mm punch radius), V-die (12 die gap, 0.8 shoulder and rectangular specimen (50 length, 5 width...
