title: Effect of cavity preparation design and ceramic type on the stress distribution, strain and fracture resistance of CAD/CAM onlays in molars

description: Abstract Objective This study aimed to evaluate the effect of the cavity preparation and ceramic type on the stress distribution, tooth strain, fracture resistance and fracture mode of human molar teeth restored with onlays. Material and Methods Forty-eight molars were divided into four groups (n=12) with assorted combinations of two study factors: BL- conventional onlay preparation with boxes made from leucite ceramic (IPS-Empress CAD, Ivoclar Vivadent); NBL- conservative onlay preparation without boxes made from leucite ceramic; BD- conventional onlay preparation with boxes made from lithium disilicate glass ceramic (IPS e.max CAD, Ivoclar Vivadent); NBL- conservative onlay preparation with boxes made from lithium disilicate glass ceramic cuspal deformation (µS) was measured at 100 N and at maximum fracture load using strain gauge. Fracture resistance (N) was measured using a compression test, and the fracture mode was recorded. Finite element analysis was used to evaluate the stress distribution by modified von Mises stress criteria. The tooth strain and fracture resistance data were analyzed using the Tukey test and two-way ANOVA, and the fracture mode was analyzed by the chi-square test (α=0.05). Results The leucite ceramic resulted in higher tooth deformation at 100 N and lower tooth deformation at the maximum fracture load than the lithium disilicate ceramic (P&lt;0.001). The lithium disilicate ceramic exhibited higher fracture resistance than the leucite ceramic (P&lt;0.001). The conservative onlay resulted in higher fracture strength for lithium disilicate ceramic. Finite element analysis results showed the conventional cavity preparation resulted in higher stress concentration in the ceramic restoration and remaining tooth than the conservative onlay preparation. The conservative onlays exhibited increased fracture resistance, reduced stress concentration and more favorable fracture modes. Conclusion Molars restored with lithium disilicate CAD-CAM ceramic onlays exhibited higher fracture resistance than molars restored with leucite CAD-CAM ceramic onlays.

title: In vitro Analysis of the Interaction between Human Serum Albumin and Semi-Synthetic Clerodanes

description: The interaction between HSA and two semi-synthetic potential anti-cancer agents derived from trans -dehydrocrotonin-methyl-hydrazone (MHDCTN) and phenyl-hydrazone (PHDCTN) was evaluated under physiological conditions at 296, 303 and 310 K by multi-spectroscopic techniques and molecular docking calculations. Steady state fluorescence quenching indicated a ground state association (static quenching) for both samples; however, the quenching induced by PHDCTN was not essentially static and can be accompanied by a dynamic quenching mechanism. The binding is strong (modified Stern-Volmer binding constant (Ka) ca. 105 M-1), causing a very weak perturbation on the secondary structure of the protein and there is just one main binding site for both samples (Sudlow’s site I). Molecular docking results suggested hydrogen bonding and hydrophobic interactions as the main binding forces for both samples.

title: Support to the assessment process of the water supply service in Rio Grande do Norte State: a multicriteria approach

description: ABSTRACT Water supply and sewage are two essential services to society, especially in Brazil, where historically there has been a deficit of these crucial services. Moreover, it is also known that such services involve many actors who often have conflicting perspectives, characteristics of multicriteria problems. Thus, this paper aimed to evaluate the water supply service in eight cities of Rio Grande do Norte State, Brazil. Eleven criteria were selected, considering operational, financial and water quality aspects. We adopted the TOPSIS method to support the multicriteria decision. In addition, the entropy method was used to obtain the weights for each criterion. The results showed the city of Lagoa Nova as the alternative with the best water supply service of the alternatives studied. In contrast, Santana do Matos was the city with the worst water supply assessment of all the studied alternatives.

title: Cyclic flexural fatigue resistance of NiTi Controlled Memory and Blue Technology instruments after torsional preloading

description: Abstract Objective The aim of this study was to evaluate the influence of torsional preloading on the cyclic flexural fatigue resistance of thermally treated NiTi instruments. Material and Methods Ten new instruments New Hyflex CM (HF 30.06; Coltene/Whaladent Inc.), Typhoon CM (TYP 30.06; Clinician's Choice Dental Products) and Vortex Blue (VB 30.06; Dentsply Tulsa Dental) were chosen, based on geometry and specific characteristics of the manufacturing process. The new instruments of each system were tested in a bench device to determine their fatigue resistance through mean value of number of cycles to failure (Nf) (Control Group – CG). Another group of 10 new HF, TYP and VB instruments were submitted to 20 cycles of torsional straining between 0° and 180° (Experimental Group – EG) and then submitted to fatigue until rupture under the same conditions of the CG. Tested instruments were examined by scanning electron microscopy (SEM). Data were analyzed using one-way analysis of variance and post hoc Tukey’s test (α=.05). Results Higher fatigue resistance was accomplished by HF instruments, followed by VB and TYP (p&lt;0.05). During the torsional preloading, the lowest mean torque value was observed for TYP instruments (p&lt;0.05). The torsional preload caused a significant reduction in the Nf values (p&lt;0.05) of about 20%, 39% and 45% for instruments HF, VB and TYP, respectively. Longitudinal cracks, generated during the torsional preloading, were present in VB files, but were not observed in the CM instruments (HF and TYP). Conclusions In conclusion, the flexural fatigue resistance of thermally treated instruments is diminished after cyclic torsional loading.

title: Medicine poisoning mortality trend by gender and age group, São Paulo State, Brazil, 1996-2012

description: Abstract This study looked into mortality due to medicinal drug poisoning by age, gender and intent among the population of the state of São Paulo. The adjusted time sequence of mortality due to drug poisoning was developed based on data available in the DATASUS Mortality Data System for 1996 to 2012. We checked the variables for magnitude and trends. We found an increase in adjusted mortality starting in 2005, and more so as of 2009, confirmed by a 95% CI for the average annual rate of change. (AARC) We did not find the same trend in overall mortality in the state (AARC = -0.22%, 95% CI = -1.12 - 0.69) for specific, external cause mortality (AARC = -3.14%, 95% CI = -4.75 - -1.49) and for mortality due to accidental drug poisoning (AARC=+9,76%, 95% IC = -12.16 – 37.14). The largest increase was found in intentional self-poisoning with medicinal drugs (AARC = +10.64%, 95% CI = 6.92 - 14.40), and among the younger subjects (largest magnitude). The trend in mortality due to drug poisoning in the State of São Paulo, the importance of intent and mortality among the younger population reiterate the need to implement control measures.

title: Degradation of Aqueous Paraquat by Surface Air Plasma: A Kinetic Study

description: In this work, the kinetics of aqueous paraquat (PQ) degradation in a surface air plasma reactor was studied under a variety of experimental conditions. Additionally, stable reactive oxygen species (ROS) and reactive nitrogen species (RNS) were determined. PQ degradation followed pseudo-second order kinetics, increasing both observed rate constant (kobs) and removal efficiency by increasing the temperature. Increasing PQ concentration decreased kobs, as a constant amount of reactive species is generated at the same conditions. Both the decrease of the entropy of activation (–157.1 J K-1 mol-1) and the low value of the enthalpy of activation (+9.9 kJ mol-1) supported a bimolecular associative mechanism for producing the transition state. From the ionic strength effect, the transition state is formed by two ions of opposite charges (zAzB= –3.6). Produced RNS (nitrous and nitric acid) followed zero-order kinetics. Gaseous ozone was the only ROS identified, as hydrogen peroxide concentration was below the limit of detection.

title: Genetic gains in agronomic and technological traits of elite cotton genotypes

description: ABSTRACT The objective of this work was to estimate the predicted genetic gains with the simultaneous selection of agronomic and technological traits from elite cotton lines using selection indexes. Data from the evaluation of 36 elite lines were evaluated in three trials located in Apodi-RN in 2013 and 2014 and Santa Helena, GO, Brazil in 2013, in a randomized block design with two replicates. The agronomic traits evaluated were: plant height (PH), average boll weight (ABW), percentage of fibers (PF) and seed cotton yield (YIE). In 20 bolls from each experimental unit, the following technological fiber traits were evaluated: fiber length (UHM), fiber uniformity (UNIF), short fiber index (SFI), fiber strength (FS), elongation (ELON), micronaire (MIC), reflectance (RD) and degree of yellowing (+b). Smith and Hazel, Pesek and Baker and Mulamba and Mock selection indexes were tested for selection of the seven superior genotypes, assigning the coefficients of genetic variation (CVg) as economic weight. There were no interaction between genotypes and environments for any of the evaluated traits. Smith and Hazel index resulted in negative gains for fiber length and positive for the traits whose reduction is of interest, such as plant height, micronaire and degree of yellowing. Pesek and Baker index provided positive predictive gains for all traits of interest. However, it promoted reduction only to the degree of yellowing. Mulamba and Mock presented satisfactory gains, being the most suitable for selecting genotypes aiming at simultaneous gains in yield and fiber technological components.
