In vitro study of measures to control microbial colonization in the internal chamber of the implant and the implant-abutment system

Conclusiones: Se observó una disminución significativa en la cantidad de UFC en los grupos experimentales respecto al grupo control, lo que determina la ventaja de utilizar este tipo de antimicrobianosAbstract. Objective: To determine biofilm control measures in the internal chamber of the implant through an in vitro test. Method: Different antimicrobial agents were selected and placed in the chambers of three groups of implants. After seven days, we immersed them in a microbial suspension for incubation. We collected, cultured and incubated the samples from the chambers of each study group. Results: We detected a filtration of microorganisms into the internal chamber in all the groups of implants studied. This resulted in a higher count of colony-forming units (CFU) in the control group, whereas in the experimental groups we identified a significant reduction in the CFU count. Conclusions: We observed a significant decrease in the number of CFU in the experimental groups in relation to the control group, which determines the advantage of using this type of antimicrobials

In two studies, we investigated the developmental origins of children’s motivation to return help. In Study 1, 18- and 24-month-old toddlers were either helped or not helped by an adult, and they could subsequently provide that adult with help or else observe another person providing help. We measured children’s internal arousal, via changes in pupil d...

This article critically examines the nature of changing modalities in international development and related research in education. The consequences of contemporary trends and trajectories in these domains are considered with particular reference to their conceptual and ethical implications. Drawing on contemporary social theory, comparative and international research in education, and research ethics, the analysis focuses on North-South research and development partnerships, conceptions of ‘best practice’ in the arenas of education and development, the emergence of large-scale social and educational research mo...

The two main conclusions are (i) the need to maximise the recruitment of high-value onshore overseas students is the main financial driving force for the internationalisation of education in the UK. The income ...

We report relations between responsiveness, reciprocity, and emotional tone and functional connectivity in theta, alpha, beta, and gamma in infants ranging from 6 to 11 month of age (N = 51). Results showed frontal-posterior connectivity in theta was inversely related to all three dimensions of parent-infant interactions. Gamma and alpha connectivity were positively associated with responsiveness and emotional tone, respectively. Results are discussed in the context of the experience-dependent nature of brain development, emphasizing how parent-infant interactions might be leveraged to structure early organization of t...

In conclusion, whole-fat spray-dried powder had more round shape and showed high homogeneity of particle size, but there were many limitations in powder flowability. Mealworm powders had better flowability and other physical properties, such as emulsion and foaming activities, when the fat was removed. However, the solvent-defatted powders, which lacked fat, were less desirable to consumers due to their lack of flavor. Among the press-defatted mealworm powders, the one milled by a jet mill showed better flowability and physicochemical properties compared to the other powders.

This study focused on investigating quality changes of thermally processed kale purée using an integrated targeted and untargeted approach. Low, medium, and high processing intensities (carried out at 70, 90, and 128 °C) were selected based on predetermined shelf-life targets: frozen-thawed, refrigerated, and ambient storage, respectively. The results show that that physicochemical properties determining consumer acceptability were largely dependent on the treatment intensity. The high intensity treatment resulted in the least favorable quality characteristics (distinct brown color, chlorophyll and vitamin C d...
