Dental Treatment under General Anesthesia in Healthy and Medically Compromised/Developmentally Disabled Children: A Comparative Study

Aim: To compare the type, number of procedures and working time of dental treatment provided under dental general anesthesia (DGA) in healthy and medically compromised/developmentally disabled children (MCDD children). Design: This cross-sectional prospective study involved 80 children divided into two groups of 40 children each. Group 1 consisted of healthy and Group 2 consisted of MCDD children. Results: Healthy children needed more working time than MCDD children, the means being 161±7.9 and 84±5.7 minutes, respectively (P= 0.0001). Operative dentistry and endodontic treatments showed a significant statistical difference (P= 0.0001). The means of procedures were 17±5.0 for healthy children and 11±4.8 for MCDD children (P= 0.0001). Conclusions: Healthy children needed more extensive dental treatment than MCDD children under DGA. The information from this sample of Mexican children could be used as reference for determining trends both within a facility as well as in comparing facilities in cross-population studies

HI Observations of the Supermassive Binary Black Hole System in 0402+379

We have recently discovered a supermassive binary black hole system with a projected separation between the two black holes of 7.3 parsecs in the radio galaxy 0402+379. This is the most compact supermassive binary black hole pair yet imaged by more than two orders of magnitude. We present Global VLBI observations at 1.3464 GHz of this radio galaxy, taken to improve the quality of the HI data. Two absorption lines are found toward the southern jet of the source, one redshifted by 370 +/- 10 km/s and the other blueshifted by 700 +/- 10 km/s with respect to the systemic velocity of the source, which, along with the results obtained for the opacity distribution over the source, suggests the presence of two mass clumps rotating around the central region of the source. We propose a model consisting of a geometrically thick disk, of which we only see a couple of clumps, that reproduces the velocities measured from the HI absorption profiles. These clumps rotate in circular Keplerian orbits around an axis that crosses one of the supermassive black holes of the binary system in 0402+379. We find an upper limit for the inclination angle of the twin jets of the source to the line of sight of 66 degrees, which, according to the proposed model, implies a lower limit on the central mass of ~7 x 10^8 Msun and a lower limit for the scale height of the thick disk of ~12 pc .Comment: 20 pages, 7 figures.

Synthesis and characterization of silver vanadates thin films for photocatalytic applications

Silver vanadates thin films were deposited by a hybrid deposition system combining laser ablation and thermal evaporation. A high purity vanadium target was ablated using the third harmonic of a Nd:YAG laser whereas high purity silver pellets were evaporated. The as-deposited thin films were subjected to thermal treatments at 400 °C to obtain crystalline films. For films without Ag amorphous V2O5 thin films were deposited and as the Ag is incorporated in the material different silver vanadates were obtained. The effect of the silver load on the composition, structure, optical properties, surface morphology and photocatalytic response of the deposited films was studied. The film composition, determined by X-ray photoelectron spectroscopy, reveals Ag contents from 5.5 to 18.9 at.%. The crystalline phases formed were identified by micro-Raman Spectroscopy; the results indicate the formation of three silver vanadates depending on the silver content. The morphology was observed using scanning electron microscopy, the filmś surface changes from a smooth surface to belts covering the surface and finally Ag nanoparticles are observed at the higher Ag contens. Optical properties determined from UV–vis reveal the presence of the surface plasmon signal in films containing silver. The films were tested in the photocatalytic degradation of Malachite Green dye reaching maximum degradations degrees close to 53% under solar irradiation. Reactive species trapping experiments suggest that O2 − produced by the O2 reduction via the photogenerated electrons drives the photodegradation mechanismCB-168827 CB-240998 F.

Oregano essential oil-pectin edible films as anti-quorum sensing and food antimicrobial agents

Edible films can be used as carriers for antimicrobial compounds to assure food safety andquality; in addition, pathogenesis of food bacteria is related to a cell to cell communicationmechanism calledquorum sensing(QS). Oregano essential oil (OEO) has proved to beuseful as food antimicrobial; however, its foodapplications can be compromised by thevolatile character of its active constituents.Therefore, formulation of edible films containingOEO can be an alternative to improve its food usages. QS inhibitory activity of OEO andpectin-OEO films was evaluated usingChromobacterium violaceumas bacterial model.Additionally, antibacterial activity was tested againstEscherichia coliO157:H7,SalmonellaCholeraesuis,Staphylococcus aureus,andListeria monocytogenes. OEO was effective toinhibit bacterial growth at MIC of 0.24 mg/mL for all tested bacteria and MBC of 0.24,0.24, 0.48, and 0.24 mg/mL againstE. coliO157:H7,S.Choleraesuis,S. aureus, andL.monocytogenes, respectively. Pectin-films incorporated with 36.1 and 25.9 mg/mL of OEOshowed inhibition diameters of 16.3 and 15.2 mm forE. coliO157:H7; 18.1 and 24.2 mm forS.Choleraesuis; 20.8 and 20.3 mm forS. aureus; 21.3 and 19.3 mm forL. monocytogenes,respectively. Pectin-OEO film (15.7 mg/mL) was effective againstE. coliO157:H7 (9.3 mm),S. aureus(9.7 mm), andL. monocytogenes(9.2 mm), but not forS.Choleraesuis. Allconcentrations of OEO (0.0156, 0.0312, 0.0625 and 0.125 mg/mL) and pectin-OEO films(15.7, 25.9 and 36.1 mg/mL) showed a significant anti-QS activity expressed as inhibition ofviolacein production byC. violaceum. Additionally, the application of pectin-OEO films waseffective reducing total coliforms, yeast, and molds of shrimp and cucumber slices storedat 4◦C during 15 d.These results demonstrated the potential of pectin films enriched withOEO as food related microorganisms and QS inhibitorsFil: Alvarez, María Victoria.

A Compact Supermassive Binary Black Hole System

We report on the discovery of a supermassive binary black hole system in the radio galaxy 0402+379, with a projected separation between the two black holes of just 7.3 pc. This is the closest black hole pair yet found by more than two orders of magnitude. These results are based upon recent multi-frequency observations using the Very Long Baseline Array (VLBA) which reveal two compact, variable, flat-spectrum, active nuclei within the elliptical host galaxy of 0402+379. Multi-epoch observations from the VLBA also provide constraints on the total mass and dynamics of the system. Low spectral resolution spectroscopy using the Hobby-Eberly Telescope indicates two velocity systems with a combined mass of the two black holes of ~1.5 x 10^8 solar masses. The two nuclei appear stationary while the jets emanating from the weaker of the two nuclei appear to move out and terminate in bright hot spots. The discovery of this system has implications for the number of close binary black holes that might be sources of gravitational radiation. Green Bank Telescope observations at 22 GHz to search for water masers in this interesting system are also presented.Comment: 34 pages, 7 figures, Accepted to The Astrophysical Journa

La efectividad de la terapia de aceptación y compromiso como tratamiento para el trastorno de ansiedad social: revisión aplicada

Currently, the efficacy of cognitive behavioral therapy is known, which is why it is positioned as the first option for the treatment of different disorders. One of them is social anxiety disorder, a frequent disorder that is increasing considering the current digitalized context. However, there is a significant group of clients who do not respond or are remittent to treatment. Therefore, the objective of this study is to identify the efficacy of acceptance and commitment therapy in the treatment of social anxiety disorder. An exhaustive review of scientific articles that evaluated both variables was carried out, for which 10 investigations were selected from the Web of Science, Scopus, Scielo and Ebsco databases. The results show that acceptance and commitment therapy is effective for social anxiety disorder, reaching almost the same level of effectiveness as cognitive behavioral therapy. It not only helps to reduce symptoms but also influences the development of other skills.Currently, the efficacy of cognitive behavioral therapy is known, which is why it is positioned as the first option for the treatment of different disorders.
