title: Subsidies for propagation of native species in Brazil with medicinal potential: Calophyllum brasiliense Cambess

description: Abstract: Calophyllum brasiliense Cambess. (guanandi) is a native species with medicinal potential and also generates expectation for commercial use (wood) and for recovery of degraded areas. These seeds have physical and mechanical dormancy, requiring techniques for dormancy release; knowledge of seed and seedling morphology that assists laboratory analysis and propagation of the species is also necessary. The objective of this study was to describe the morphological structures of the seeds and normal and abnormal seedlings of guanandi, and also investigate if complete extraction of the endocarp and the seed coat to overcome dormancy will affect the morphology and initial plant development, and consequently production of transplants. Guanandi seeds are large (1000 seed weight of 1480.9 g) with a hard seed coat; cotyledons account for most of the embryo and serve as a reserve; the embryonic axis is small (1.0-2.0 mm) in relation to the seed, yet it is differentiated. The seedlings have hypogeal cryptocotylar germination, with cotyledonary petioles, taproot, and epicotyl developing into a long stem and a tip protected by cataphylls. The main abnormalities in seedlings are related to the root system. Extraction of the endocarp and seed coat does not alter the morphology of seedlings and promotes their greater development, which may be an advantageous strategy.

title: Evaluation of salivary oxidative parameters in overweight and obese young adults

description: ABSTRACT Background Obesity is characterized by a deposition of abnormal or excessive fat in adipose tissue, and is linked with a risk of damage to several metabolic and pathological processes associated with oxidative stress. To date, salivary oxidative biomarkers have been minimally explored in obese individuals. Thus, the aim of this study was to assess the concentrations of salivary oxidative biomarkers (ferric-reducing antioxidant power, uric acid, sulfhydryl groups) and lipid peroxidation in obese and overweight young subjects. Materials and methods Levels of lipid peroxidation, ferric-reducing antioxidant power, uric acid, and SH groups were determined in the saliva and serum of 149 young adults, including 54 normal weight, 27 overweight, and 68 obese individuals. Anthropometric measurements were also evaluated. Results Salivary levels of ferric-reducing antioxidant power, sulfhydryl groups, and lipid peroxidation, as well as serum levels of ferric-reducing antioxidant power, uric acid, and lipid peroxidation were higher in obese patients when compared with individuals with normal weight. There were correlations between salivary and serum ferric-reducing antioxidant power and salivary and serum uric acid in the obese and normal-weight groups. Conclusions Our results indicate that the increase in salivary levels of ferric-reducing antioxidant power, sulfhydryl groups, and lipid peroxidation, and serum levels of ferric-reducing antioxidant power, uric acid, and lipid peroxidation could be related to the regulation of various processes in the adipose tissue. These findings may hold promise in identifying new oxidative markers to assist in diagnosing and monitoring overweight and obese patients.

title: Study of the scientific collaboration network in nanotechnology at the Brazilian Agricultural Research Corporation

description: Abstract The study of scientific collaboration allows us to observe, for instance, results that can guide research management in an organization. In this sense, the objective of this study is to analyze the network for scientific collaboration in nanotechnology at the Brazilian Agricultural Research Corporation, and the evolution thereof, since this is a field which has produced innovative results for Brazilian agribusiness. To this end, the methodology of Social Network Analysis was used in order to identify co-authorship connections and to analyze the evolution of this network. The origin of the data was Agricultural Research Database (Base de Dados da Pesquisa Agropecuária), which is freely accessible to the public. The analysis was based on scientific production from 2006 to 2014. For the analysis of network evolution, this timeframe was divided into three periods, consisting of the periods from 2006 to 2008, 2009 to 2011, and 2012 to 2014. The results showed that the data represents a significant timeframe for analysis, nearly 10 years, providing the perception that, insofar as the evolution of the network is concerned, it evidently occurred in a gradual manner, highlighting the fact that scientific collaboration in nanotechnology at Embrapa becomes increasingly effective and dynamic.

title: Evaluation of a Collaborative Strategy: a case study in the Port wine industry

description: ABSTRACT The rapid and all-encompassing changes in regional and world wine markets have stimulated us to carry out this study. Accordingly, based on the competitiveness of an important Port wine producer in Portugal, this article analyzes a strategic alliance between this company and another important multinational one that is present in many different worldwide distribution markets. Basically, the article seeks to understand, on the one side, the impact of a strategic alliance on a small Port wine producer when becoming involved with a multinational company, and, on the other hand, to identify differences, before and after the alliance, to the markets where the small company was made present. This work is centered on a case study and involves the use of econometrics methodologies that analyze panel data, in order to grasp differences of strategic pre- and post-alliance actions. The conclusions are important, since they allow one to compare, on one hand, difference between the company´s performance over two different time horizons. On the other hand, econometrics methods are robust, since they allow one to come to relational conclusions, keeping the case study in mind.

title: Ethical and moral development: aspects relating to professional training in Dentistry

description: ABSTRACT Objective: To assess the progression of a public university's dental students through stages of moral development during the course. Methods: A cross-sectional study with 115 students (from the 1st to the 7th semester), to whom the "Opiniões sobre problemas sociais" test, adapted and translated to the Portuguese language, was applied. Results: The collected answers were charted according to the test manual's guidelines and data were analyzed by the GraphPad Prism software 6.0 and STATA v.13. Principal morality score values, expressed as a P value (%), were 40.26%; 39.32%; 36.45% and 36.27% for the 1st, 3rd, 5th and 7th semesters, respectively, with no statistically significant difference between the groups (ANOVA, p = 0.52). Conclusion: Students' degrees of morality did not vary significantly among the semesters compared, indicating the need for a reorientation of teaching-learning practices that takes the potential of transformative learning into account.

title: Permian-Triassic maturation and multistage migration of hydrocarbons in the Assistência Formation (Irati Subgroup), Paraná Basin, Brazil: implications for the exploration model

description: New lines of geological evidence strongly suggest that the main period of hydrocarbon maturation within Assistência Formation should be Permian-Triassic, stimulated by a high geothermal gradient that also sustained various manifestations of hydrothermal activity. Three main stages of fluid/hydrocarbon migration can also be inferred on the basis of multiscale observations: confined flow in late Permian to Triassic times, depending on the local build-up of fluid pressures; heterogeneous flow in Lower Cretaceous, triggered by a rejuvenated temperature gradient assisted by the early developed permeability conditions; and a late flow possibly driven by local pressure gradients, after complete cooling of dolerite dykes/sills. The early maturation and multistage migration of hydrocarbons have significant consequences in the design of exploration models to be applied in Paraná Basin.

title: Musculoskeletal symptoms in taxi driver Rio Branco, Acre: prevalence and associated factors

description: OBJECTIVE: To analyze the prevalence and factors associated with musculoskeletal symptoms in taxi drivers in Rio Branco, Acre.METHODS: Cross-sectional population-based study with 321 drivers. It was used a questionnaire with closed questions on musculoskeletal symptoms and associated variables. Multiple logistic regression was used to identify factors associated with symptoms in the last 12 months.RESULTS: The prevalence of musculoskeletal symptoms was 72.0%. The body parts with the highest prevalence were: lumbar (49.5%) and neck (29.9%). Poor self-assessed health associated itself with symptoms all body regions. The situation of living with more than 4 people at home was associated with symptoms in the regions of the upper trunk and the upper and lower limbs. Living with a partner was associated with symptoms in the regions of the upper and lower torso. Linear trend of increasing BMI with the symptoms on the upper trunk and lower limbs was found. The condition of having less than 5 years of formal studying and having 2 or more children showed association with symptoms in the lower trunk and upper limbs, respectively. The alarming prevalence of musculoskeletal symptoms in taxi drivers suggests the need for occupational health programs for these workers.

title: The scientific structure of competitive intelligence

description: Abstract The scientific framework of a new field of knowledge is the foundation for its recognition as a scientific discipline. Considering that competitive intelligence is a recent field of knowledge, the main purpose of this study is to propose a scientific framework for competitive intelligence and a hierarchical research system with practical, scientific and epistemological perspectives levels. Other purposes include identifying the paradigm of competitive intelligence, enumerating its theories and models, and listing the solutions for real world problems proposed by this field. This is a descriptive research that uses the survey method and statistical analysis of variable behavior from a systemic model for defining scientific objects, using a sample of scientific articles published both in English and Portuguese. The results showed the existence of three scientific levels of research in this field. The following three paradigms support research in this field: a theoretical framework that supports studies in the field that are used to help solving practical problems; applied studies, particularly those related to improving the process of competitive intelligence; and those that contribute to other organizational processes. It may be concluded that the explicit scientific framework and a hierarchical research system proposed in the epistemological, scientific and practical levels are suitable for understanding this discipline.

title: FREQUENCY OF QUIESCENT FUNGI AND POST-HARVEST ALTERNATIVE MANAGEMENT OF STEM END ROT IN PAPAYA

description: ABSTRACT The aim of this study was to evaluate the frequency of quiescent fungi and the effect of phosphites under modified atmosphere on Lasiodiplodia theobromae in papaya. The fruits were treated with a range of doses of phosphites and their actions evaluated under conditions of ambient and modified atmosphere. Of the eight fungal genera found, Lasiodiplodia was the most common. No interaction was observed between the evaluated factors and only atmosphere and dose were independently significant. The usage of phosphites and modified atmosphere reduced the severity of the disease, and did not affect the chemical properties of the fruits.

title: The origin of chaos ? the mobility crisis in Rio de Janeiro and the threat to urban health

description: This article approaches urban mobility and its consequences to urban health. In addition, it presents recent studies about the subject and the historical reasons that have transformed the automobile into the main Brazilian means of transport, at least to the higher classes, to the detriment of public transport, used by the great mass of workers. The excessive use of automobiles affects air quality, and this, added to stress, vibration and noise, damages the health and the quality of life of the population that is exposed to the problems caused by long traffic jams. In Rio de Janeiro, this phenomenon has reached a delicate stage, in the moment that the metropolis is preparing itself to receive the 2014 World Cup and the 2016 Olympic Games.
