Ciência da carne: a linguagem gráfica da anatomia humana

This monograph seeks to provide an exposition and theoretical examination of Ciência da Carne (“Science of the Flesh”), a series of artworks in woodcut printing executed after research into the artistic aspects of Human Anatomy, done throughout the Graduate Course in Visual Arts at UNESP’s Art Institute. Traditional procedures of naturalistic representation of the human figure often adopt the scientific basis of Anatomy as a means of interpreting the surface contours of the body from its inside out. The historical connection between Anatomy and Art, however, is not merely accidental, for it is integral to the development of both disciplines, which find themselves deeply related in the human impulse for self-discovery and reinvention of its own likeness. The series of artworks collected in Ciência da Carne explores, through the particular graphical language provided by woodcut printing, abstract arrangements of isolated anatomical elements, at once removed from the context of traditional figurative representation and from the didactic goals of medical illustration.

Repair of composites: Effect of laser and different surface treatments

Objectives: This study investigated the repairs of resin composite restorations after using different surface treatments.Design: Eighty four truncated cones of Filtek Z350 were prepared and thermo-cycled (20,000 cycles). Surfaces were roughened with diamond bur and etched with 37% phosphoric acid. Those cones were divided into 7 groups (N=12): 1) Prime&Bond 2.1; 2) aluminum oxide sandblasting+Prime&Bond 2.1; 3) Er:YAG laser treatment+Prime&Bond 2.1; 4) 9.6% hydrofluoric acid for 2 min-Fsilane coupling agent.; 5) silane coupling agent; 6) auto-polymerized acrylic monomer+Prime&Bond 2.1; 7) Adper Scothbond SE. Teflon device was used to fabricate inverted truncated cones of repair composite over the surface-treated. The bonded specimens were stressed to failure under tension. The data were analyzed with oneway ANOVA and Tukey tests.Results: Mean repair strengths (SD, in MPa) were, Group-2: 18.8a; Group-1: 18.7a; Group-6: 13.4ab; Group-7: 9.5bc; Group-3: 7.5bcd; Group-4: 5.2cd; Group-5: 2.6d.Conclusions: The use of diamond bur and a conventional adhesive and the use of aluminum oxide sandblasting prior to adhesive provided a simple and cost-effective solutions to composite repair. Er:YAG laser, silane alone, 9.6% hydrofluoric acid plus silane or a self-etching adhesive results in inferior composite repair strengths. (C) 2015 Elsevier Ltd. All rights reserved.

Estratégias de enfrentamento em jogadores de futebol

The aim of this study was to identify scores of interest related to coping strategies used by professional and amateur football players. Participants were 134 male football players, 71 professionals (age=22,77±3,98 years) and 63 amateurs (age=17,18±0,84) from three teams participating on the First Division State Championship). The players answered individually to the Coping with Problems Scale. Significance level was P<0.05. When coping strategies were compared based on game position and player category (professional or amateur), lateral player amateurs used more wishful thinking /religious practices (P=0.042) than professionals. Coping Focused Problem was the most used strategy used by both the professionals and amateurs, except the amateur laterais, who used more wishful thinking /religious practices.

Patients on the Waiting List for Liver Transplantation: Caregiver Burden and Stress

Over the last few decades, informal caregivers of patients with chronic diseases have received more attention, and there is a growing volume of studies demonstrating high rates of burden, stress, and mental disorders in this group of individuals. The objective of this study was to evaluate the burden, stress, and psychosocial characteristics of informal caregivers of liver transplantation candidates. Participants were assessed by individual evaluations with the following instruments: a semi-structured interview, the Caregiver Burden Scale, the Inventario de Sintomas de Stress para Adultos de Lipp, and the Beck Depression Inventory. The Mann-Whitney test was used for statistical analysis with a significance level of 0.05. The characteristics of the study group (n = 61) were similar to those of groups in other studies with respect to gender (82% were women), kinship (64% were spouses), and age (the mean age was 47.6 years). The main stressors identified by the participants were as follows: doubts about ways to react in a crisis or in emergency situations (42.6%), mood swings of the patient (29.5%), and care involving food and medications (27.9%). Approximately 25% of the caregivers reported that they felt unprepared to adequately perform their roles. Data analysis indicated a greater burden overall on caregivers when the patient`s Model for End-Stage Liver Disease score was greater than or equal to 15 points (P = 0.041). Furthermore, caregivers of patients with alcoholic liver disease showed higher depression (P = 0.034) and overall burden scores (P = 0.031) versus caregivers of patients with liver disease due to other etiologies. In conclusion, the participants showed significantly high levels of burden, stress, and depression. Support measures and caregiver preparation should be implemented by health care providers.

Impact of different fluoride concentrations and pH of dentifrices on tooth erosion/abrasion in vitro

Background: This in vitro study analysed the effect of different fluoride concentrations in acidic or neutral liquid dentifrices in protecting enamel and dentine from erosive and abrasive wear. Methods: Bovine enamel and dentine specimens (n = 132) were randomly allocated to 11 groups (each n = 12): experimental liquid dentifrices with 550 ppm F, 1100 ppm F, 5000 ppm F or 0 ppm F/placebo (each at pH 4.5 and pH 7.0); and commercial dentifrices with 550 ppm F (Colgate Baby, pH 7.0), 1100 ppm F (Crest, pH 7.0) and 5000 ppm F (Duraphat, pH 7.0). The specimens were subjected to erosion for 90 seconds, 4 times/day, over 7 days. Immediately after the first and last erosion, the specimens were brushed for 15 seconds using one of the dentifrices. Tooth wear was measured profilometrically (lm) and analysed by ANOVA (p < 0.05). Results: All fluoridated liquid dentifrices significantly reduced enamel wear compared to the placebo and commercial dentifrices. Only liquid dentifrices with 1100 and 5000 ppm F significantly reduced dentine wear compared to placebo dentifrice. The pH had no effect, but the consistency had a significant impact on the effect of dentifrices. Conclusions: Liquid dentifrices with high F concentration appear to be a good option to prevent tooth wear

Semantic integration of gene expression analysis tools and data sources using software connectors

Abstract Background The study and analysis of gene expression measurements is the primary focus of functional genomics. Once expression data is available, biologists are faced with the task of extracting (new) knowledge associated to the underlying biological phenomenon. Most often, in order to perform this task, biologists execute a number of analysis activities on the available gene expression dataset rather than a single analysis activity. The integration of heteregeneous tools and data sources to create an integrated analysis environment represents a challenging and error-prone task. Semantic integration enables the assignment of unambiguous meanings to data shared among different applications in an integrated environment, allowing the exchange of data in a semantically consistent and meaningful way. This work aims at developing an ontology-based methodology for the semantic integration of gene expression analysis tools and data sources. The proposed methodology relies on software connectors to support not only the access to heterogeneous data sources but also the definition of transformation rules on exchanged data. Results We have studied the different challenges involved in the integration of computer systems and the role software connectors play in this task. We have also studied a number of gene expression technologies, analysis tools and related ontologies in order to devise basic integration scenarios and propose a reference ontology for the gene expression domain. Then, we have defined a number of activities and associated guidelines to prescribe how the development of connectors should be carried out. Finally, we have applied the proposed methodology in the construction of three different integration scenarios involving the use of different tools for the analysis of different types of gene expression data. Conclusions The proposed methodology facilitates the development of connectors capable of semantically integrating different gene expression analysis tools and data sources. The methodology can be used in the development of connectors supporting both simple and nontrivial processing requirements, thus assuring accurate data exchange and information interpretation from exchanged data.
