Abstract: Objective: The aim of this study was to evaluate the surface roughness of acrylic resin according to the manipulation method.Methods: Sixty specimens were randomly divided into four groups (n=15) according to the manipulation method: G1 - addition with pressure, G2 - addition without pressure, G3 - mass with pressure and G4 - mass without pressure. After resin polymerization, all specimens were submitted to finishing with abrasive paper and mechanical polishing. Topographical surface analysis surfaces was performed twice on each sample using the rugosimeter. Results: The results were statistically analyzed and means were: G1 - 0,130μm; G2 - 0,120μm, G3 - 0,218μm e G4 - 0,192μm. ANOVA for one criterion and the Tukey test showed significant difference between G1 and G3, G2 and G3, G2 and G4. Conclusion: The manipulation method seems to affect the physical characteristics of auto polymerized acrylic resin. The addition manipulation method decreased the surface roughness.

Journal of Applied Oral Science , 2012, DOI: 10.1590/S1678-77572012000100016
Abstract: objective: the aim of this study was to assess the impact of blood contamination on shear bond strength (sbs) and bond failure pattern of metallic brackets bonded using a new hydrophilic resin. material and methods: eighty human premolars were randomly allocated into 4 groups (n=20) according to the bonding material and contamination pattern. gi: brackets bonded with the transbond xt conventional system without contamination; gii: brackets bonded with the transbond xt conventional system with blood contamination; giii: brackets bonded with the transbond self etching primer and transbond plus color without contamination; giv: brackets bonded with the transbond self etching primer and transbond plus color with blood contamination. the specimens were stored in distilled water at 37°c for 24 h and then submitted to sbs test at a crosshead speed of 0.5 mm/min. after bond failure, the enamel surfaces were observed under an optical microscope at 40x magnification. results: blood contamination decreased (p<0.05) shear bond strength when both the hydrophobic (gii) and the hydrophilic resin (giv) were used. however, the bond strength of transbond color change group was significantly higher (p<0.05) than that of the transbond xt conventional system group under blood contamination condition. under dry conditions no difference was observed between the hydrophobic and hydrophilic resin groups. regarding the bond failure pattern, when blood contaminated the enamel, the adhesive remnant index (ari) showed predominance of scores 0 and 1, which indicates low adhesion to enamel. conclusions: although there was a significant decrease in the shear bond strength for both adhesive systems under blood contamination, the hydrophilic system showed significantly higher bond strength than the hydrophobic resin adhesive. therefore, it is advisable to use the hydrophilic resin under risk of blood contamination.

Abstract: introduction: a functional variable number of tandem repeats (vntr) polymorphism of the promoter region of the monoamine oxidase a (maoa) gene has been described and many studies have investigated the association of this polymorphism with human behaviors, as well as with several psychiatric disorders. objective: this study aimed to review the literature on the role of the vntr functional polymorphism of the promoter region of the maoa gene on the modulation of human behavior for the development of psychiatric disorders. method: searches on the medline, embase, web of science and psycinfo databases were performed including works from january 1998 to june 2009. the words used were: "maoa and human behavior" and "maoa and psychiatry". results: several studies were found (n = 3,873). after the selection process, 109 papers were included in the review. there was found an association of maoa low activity alleles with antisocial personality disorder, conduct disorder, adhd, pathological gambling, and substance abuse. high activity alleles were associated with neuroticism, anorexia nervosa and depression and anxiety disorders. there was no association between the maoa polymorphisms and bipolar disorder and schizophrenia. discussion: the main findings, summarized in this paper, support a role of maoa vntr polymorphism in some psychiatric disorders although some divergences were found due to methodological difficulties in genetic studies. in general, the studies associated the low activity alleles with impulsivity and aggressive behavior ("hyperactive behaviors"), and the high activity alleles of the gene with "hypoactive behaviors", such as depression and anxiety, which demonstrates a modulation of the maoa enzyme in "hyperactive" and "hypoactive" disorders.
Possible Magnetic Resonance Signal Due to the Movement of Counterions around a Polyelectrolyte with Rotational Symmetry  [PDF]
José A. Fornés
Advances in Nanoparticles (ANP) , 2015, DOI: 10.4236/anp.2015.41002
Abstract: Experimental, theoretical and computational studies revealed that the characteristic time scales involved in counterion dynamics in polyelectrolytes systems might span several orders of magnitude ranging from subnanosecond times to time scales corresponding to acoustic-like phonon mode frequencies, with an structural organization of counterions in charge density waves (CDWs). These facts raise the possibility of observing Magnetic Resonance (MR) signals due to the movement of counterions in polyelectrolytes. In case that this signal is detected in macroions or other biological systems, like micelles, vesicles, organeles, etc. with rotational symmetry, this method opens a new tool to measure with precission the counterions velocity.
Hydrodynamic Interactions Introduce Differences in the Behaviour of a Ratchet Dimer Brownian Motor  [PDF]
José A. Fornés
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2015, DOI: 10.4236/jbnb.2015.62008
Abstract: We use the Brownian dynamics with hydrodynamic interactions simulation in order to describe the movement of an elastically coupled dimer Brownian motor in a ratchet potential. The only external forces considered in our system were the load, the random thermal noise and an unbiased thermal fluctuation. We observe differences in the dynamic behaviour if hydrodynamic interactions are considered as compared with the case without them. In conclusion, hydrodynamic interactions influence substantially the dynamics of a ratchet dimer Brownian motor; consequently they have to be considered in any theory where the molecular motors are in a liquid medium.
Temperature Fluctuations in a Rectangular Nanochannel  [PDF]
José A. Fornés
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2015, DOI: 10.4236/jbnb.2015.63011
Abstract: We consider an incompressible fluid in a rectangular nanochannel. We solve numerically the three dimensional Fourier heat equation to get the steady solution for the temperature. Then we set and solve the Langevin equation for the temperature. We have developed equations in order to determine relaxation time of the temperature fluctuations, τT = 4.62 × 10-10s. We have performed a spectral analysis of the thermal fluctuations, with the result that temporal correlations are in the one-digit ps range, and the thermal noise excites the thermal modes in the two-digit GHz range. Also we observe long-range spatial correlation up to more than half the size of the cell, 600 nm; the wave number, q, is in the 106 m-1 range. We have also determined two thermal relaxation lengths in the z direction: l1 = 1.18 nm and l2 = 9.86 nm.
