The aim of the study is to evaluate the influence of surface-treatment methods with and without the use of a retention hole on the shear bond strength of a resin composite adhered to amalgam using an adhesive system. Amalgam specimens were divided into six groups. Group 1 (Bur) specimens were roughened with a diamond bur, Group 2 (Al2O3) specimens were sandblasted with a 50 m aluminum oxide powder, Group 3 (CoJet (R)) specimens were sandblasted with 30 mu m CoJet (R) Sand, Group 4 (Bur + Rh) specimen surfaces were prepared with a retention hole 1 mm in diameter and 1 mm deep and roughened with a diamond bur, Group 5 (Al2O3 + Rh) specimens were also prepared with a retention hole and sandblasted with 50 mu m aluminum oxide powder, and Group 6 (CoJet (R) + Rh) surfaces were prepared with a retention hole and sandblasted with 30 mu m CoJet (R) Sand. Resin composite cylinders were bonded onto the amalgam surfaces using Xeno (R) IV, Optibond (TM) All-In-One, Clearfil (TM) SE Bond, Adper (TM) Single Bond Plus, and Scotchbond (TM) Multi-Purpose adhesive systems. In addition, silane (Monobond S) was used for Groups 5 and 6. The shear bond was determined and statistically analyzed using two-way analysis of variance and post hoc Tukey-s tests (p <= 0.05). The surface treatment significantly affected the shear bond strengths of the adhesive systems. The shear bond strengths of Optibond (TM) All-In-One (2.661 +/- 0.48 MPa) in Group 1 and Scotchbond Multi-Purpose (3.818 +/- 0.98) in Group 4 were significantly higher than those of the other adhesive systems. Silica coating of the amalgam surface significantly improved the shear bond strength of the resin composites. The addition of a retention hole on the amalgam affects the bonding strength of the composite adhesion.

Objective: Cardiovascular disease (CVD) is the leading cause of death in Europe. One of the candidate molecule affecting epigenetic mechanisms of CVD is the SIRT1, a subclass of sirtuins, is located on the long arm of chromosome 10 (10q21.3). Particularly, the relation between 2827 A>G polymorphism of the SIRT1 positioned on exon 2, leading to conversion of histidine to arginine, and the formation of CVD is not known yet. One of the activator of SIRT1, resveratrol, is also known as a cardioprotective molecule. On the other hand, the parameters including exercise, occupation and age affect CVD. The aim of the present study was to investigate the effect of the rs144124002 (2827 A>G) single nucleotide polymorphisms (SNP) of SIRT1 and exercise-occupation-age parameters on CVD. Methods: SNP of SIRT1 were analyzed using DNA isolation, the polymerase chain reaction (PCR) and restriction fragment length polymorphism. To do so, large cohorts of CVD patients (n=293) and healthy controls (n=117) who directed Cardiology Department of Bezmialem Vakıf University, Bezmialem Vakıf University Hospital were used. Results: In this study, when we assessed CVD and control groups about 2827 A>G polymorphism, all individuals were determined as homozygous genotype. We found a positive effect between the modifications of resveratrol, exercise, age and occupation and CVD (OR=0.17; CI 95%, 0.1-0.2; p≤0.001). Conclusion: This is the first study demonstrating the correlation between the SIRT1 rs144124002 polymorphism and CVD in Turkish population.

Obesity is a multifactorial disorder resulting from the interaction between genetic, psychological, physical, environmental, and socioeconomic factors. SIRT1 gene has important effects on the regulation of adiponectin, caloric restriction, insulin sensitivity, coronary atherosclerosis, and cardiovascular diseases. The aim of this study was to investigate the association between childhood obesity and SIRT1 gene polymorphisms regarding rs7895833 A > G in the promoter region, rs7069102 C > G in intron 4, and rs2273773 C > T in exon 5 using PCR-CTPP method in 120 obese and 120 normal weight children. In this study, BMI, systolic and diastolic blood pressure, LDL cholesterol, triglyceride, and insulin levels were significantly higher and HDL-cholesterol levels were significantly lower in obese children compared to normal weight children. For rs7895833 A > G, the rate of having AG genotype and G allele was significantly higher in obese children compared to non-obese group (p T. There was no significant difference for rs7069102 C > G gene polymorphism between groups.
