Culture and exopolysaccharide production from sugarcane molasses by Gordonia polyisoprenivorans CCT 7137, isolated from contaminated groundwater in Brazil

Gordonia polyisoprenivorans CCT 7137 was isolated from groundwater contaminated with leachate in an old controlled landfill (Sauo Paulo, Brazil), and cultured in GYM medium at different concentrations of sugarcane molasses (2%, 6%, and 10%). The strain growth was analyzed by monitoring the viable cell counts (c.f.u. mL(-1)) and optical density and EPS production was evaluated at the end of the exponential phase and 24 h after it. The analysis of the viable cell counts showed that the medium that most favored bacterial growth was not the one that favored EPS production. The control medium (GYM) was the one that most favored the strain growth, at the maximum specific growth rate of 0.232 h(-1). Differences in bacterial growth when cultured at three different concentrations of molasses were not observed. Production of EPS, in all culture media used, began during the exponential phase and continued during the growth stationary phase. The highest total EPS production, after 24 h of stationary phase, was observed in 6% molasses medium (172.86 g L(-1)) and 10% (139.47 g L(-1)) and the specific total EPS production was higher in 10% molasses medium (39.03 x10(-11)g c.f.u.(-1)). After the exponential phase, in 2%, 6%, and 10% molasses media, a higher percentage of free exopolysaccharides (EPS) was observed, representing 88.4%, 62.4%, and 64.2% of the total, respectively. A different result was observed in pattern medium, which presented EPS made up of higher percentage of capsular EPS (66.4% of the total). This work is the first study on EPS production by G. polyisoprenivorans strain in GYM medium and in medium utilizing sugarcane molasses as the sole nutrient source and suggests its potential use for EPS production by G. polyisoprenivorans CCT 7137 aiming at application in biotechnological processes.

The art of being together: a social constructionist perspective on dialogic methods in the organizational context

The purpose of this project is to understand, under a social constructionist approach, what are the meanings that external facilitators and organizational members (sponsors) working with dialogic methods place on themselves and their work. Dialogic methods, with the objective of engaging groups in flows of conversations to envisage and co-create their own future, are growing fast within organizations as a means to achieve collective change. Sharing constructionist ideas about the possibility of multiple realities and language as constitutive of such realities, dialogue has turned into a promising way for transformation, especially in a macro context of constant change and increasing complexity, where traditional structures, relationships and forms of work are questioned. Research on the topic has mostly focused on specific methods or applications, with few attempts to study it in a broader sense. Also, despite the fact that dialogic methods work on the assumption that realities are socially constructed, few studies approach the topic from a social constructionist perspective, as a research methodology per se. Thus, while most existing research aims at explaining whether or how particular methods meet particular results, my intention is to explore the meanings sustaining these new forms of organizational practice. Data was collected through semi-structured interviews with 25 people working with dialogic methods: 11 facilitators and 14 sponsors, from 8 different organizations in Brazil. Firstly, the research findings indicate several contextual elements that seem to sustain the choices for dialogic methods. Within this context, there does not seem to be a clear or specific demand for dialogic methods, but a set of different motivations, objectives and focuses, bringing about several contrasts in the way participants name, describe and explain their experiences with such methods, including tensions on power relations, knowledge creation, identity and communication. Secondly, some central ideas or images were identified within such contrasts, pointing at both directions: dialogic methods as opportunities for the creation of new organizational realities (with images of a ‘door’ or a ‘flow’, for instance, which suggest that dialogic methods may open up the access to other perspectives and the creation of new realities); and dialogic methods as new instrumental mechanisms that seem to reproduce the traditional and non-dialogical forms of work and relationship. The individualistic tradition and its tendency for rational schematism - pointed out by social constructionist scholars as strong traditions in our Western Culture - could be observed in some participants’ accounts with the image of dialogic methods as a ‘gym’, for instance, in which dialogical – and idealized –‘abilities’ could be taught and trained, turning dialogue into a tool, rather than a means for transformation. As a conclusion, I discuss what the implications of such taken-for-granted assumptions may be, and offer some insights into dialogue (and dialogic methods) as ‘the art of being together’.

Prevalência e fatores associados à dor em professores de educação física em academias de ginástica da cidade do Salvador-BA

Physical Education professionals are usually exposed to excessive physical workloads that evolve into painful symptomatology and muscle and bone disorders that originate from the work-related exercises. Purposo: The goal of this study was to investigate the prevalence and factors associated with pain painful symptomatology in teachers in gymnastics academies. An analytical transversal cut study was performed involving 163 gymnastics teachers working in the main gyms in the city of Salvador-BA. For evaluation of pain, validated versions in Portuguese of the McGill Protocol and the Wisconsin Pain Inventory were used. For obtain results of descriptive statistical analysis of the collected data was performed, followed by TStudent, and Pearson and Spearman correlation tests to verify possible correlations between the presence of pain and other variables which were considered independent. Finally, for the identification of potential risk factors associated with pain, a binary logistic regression analysis was performed. For all statistical analysis, we cnsidered p< 0.05. Results: The painful symptoms was reported by 88.3% of the subjects surveyed. High pain levels were observed in 63.8% of the interviewed professionals, where the intensity varied from moderate to severe. Pain in the lumbar region was present in 55.2% of subjects. Positive correlations were found between the level of pain intensity and the variables related with the workload activity and daily life of the teachers in almost all body joints analyzed. Some factors had been verified associates to the painful sintomatologia as the age of the professionals, the daily hours load of labor work, and the lack of interval of rest between the lessons. Conclusions: We found a high prevalence in gym teachers working in the city of Salvador-BA, which interfered in various daily activities of their home and professional lives. The most affected region was the lumbar region, followed by the knees, neck, shoulders, ankles, hands, hips, feet, elbows and forearms. The factors associated with development of painful symptomatology were the age of the professionals, daily hours of work and the lack of rest intervals between lessons. The high prevalence of pain in Physical Education teachers can be regarded as a serious occupational health problem, which would demand the urgent deployment of preventive intervention programs to minimize the impact of pain among these professionals

Resting energy expenditure and carbohydrate oxidation are higher in elderly patients with COPD: a case control study

Background: Elderly patients with chronic obstructive pulmonary disease (COPD) usually have a compromised nutritional status which is an independent predictor of morbidity and mortality. To know the Resting Energy Expenditure (REE) and the substrate oxidation measurement is essential to prevent these complications. This study aimed to compare the REE, respiratory quotient (RQ) and body composition between patients with and without COPD.Methods: This case-control study assessed 20 patients with chronic obstructive pulmonary disease attending a pulmonary rehabilitation program. The group of subjects without COPD (control group) consisted of 20 elderly patients attending a university gym, patients of a private service and a public healthy care. Consumption of oxygen (O-2) and carbon dioxide (CO2) was determined by indirect calorimetry and used for calculating the resting energy expenditure and respiratory quotient. Body mass index (BMI) and waist circumference (WC) were also measured. Percentage of body fat (%BF), lean mass (kg) and muscle mass (kg) were determined by bioimpedance. The fat free mass index (FFMI) and muscle mass index (MMI) were then calculated.Results: The COPD group had lower BMI than control (p = 0.02). However, WC, % BF, FFMI and MM-I did not differ between the groups. The COPD group had greater RQ (p = 0.01), REE (p = 0.009) and carbohydrate oxidation (p = 0.002).Conclusions: Elderly patients with COPD had higher REE, RQ and carbohydrate oxidation than controls.

Dança de salão: perspectivas de satisfação e motivos de adesão

The need to practice physical activity of any kind grows day by day. People look for studios, clubs, parks, either to practice some kind of sport, gymnastics classes, workout or a good walk. Over the last few years, another option has arived arose, which is a little different from what we are used to see. We are talking about Ballroom Dance, a new alternative for thoses who wants or needs to practice some physical activity but is looking for a different environment. Ballroom Dance is growing, thanks to the media, it has been an effective option for whom seeks to fill her free time and gains benefits such as leisure, satisfaction, health and quality of live, etc. Therefore, the objectives of this study were: investigating the reasons that lead the people to look for classes like Ballroom Dance and identify the degree of satisfaction of these students regarding Ballroom Dance classes. Thirty eight students participated in this study: some came from a dance studio from Rio Claro (SP), some from a gym academy with Ballroom Dance classes from Campo Grande (MS) and some from a Ballroom Dance Program of Unesp, Rio Claro in the community. The participants of both genders, ageing between 18 to 60 years, were enpaped on Ballroom program for at least one month. They answered a questionnaire related to the issue. After analyzing the data it was confirmed that people seeks for Ballroom Dance because they like to dance, they feel pleasure to dance, besides feeling relaxed in the activity and because dancing brought them fun. Regarding the Degree of satisfaction, all of them stated being satisfied with Ballroom Dance.

Indicadores Antropométricos do Estado Nutricional de Idosas Praticantes e Não Praticantes de Exercício Fisíco na Zona Norte de São José do Rio Preto-SP

Although the regular practice of physical exercise for the maintenance of the nutritional state and quality of life is important, it is not a common habit among the elderly, especially those of the lower income social bracket. The objective was to characterize and compare according to social-economic conditions and anthropometric indexes of the nutritional state of the elderly who regularly practice and those who do not practice exercises, offered at no cost, in the Northern zone of São José do Rio Preto-SP. In this study, 110 elderly women participated, of which 60 (group P) exercised regularly and 50 did not (group NP). Group P participated in a special gym program, free of charge, for at least 2 years, 2 to 3 times a week, one hour a day. Group NP was recruited from the same location as Group P. The comparison between the groups of elderly women was proportionately distributed according to marital status, level of education, means of locomotion, results of body mass index (IMC), waist to hip ratio (RCQ) and calf circumference, using the chi-square test. Comparisons were also made of average age, per capita family income, individual income, IMC, arm and triceps skin fold measured by t-Test. Differences were not found in all the comparisons made. The variables that stood out were the IMC (overweight) and RCQ (risk of chronic diseases) results, which were above what was expected, and the high frequency of walking and riding buses for both groups of elderly women (about 60%). We came to the conclusion that the low-intensity exercise program evaluated made no difference in the nutritional profile of the elderly who also used walking as a means of getting around.

Perfil de uso de recursos ergogênicos em academias da cidade de Bauru/SP

The increasing number of gyms and their patrons increasingly concerned about the health, appearance and aesthetics propagated by the media and the supply of ergogenic both food as hormonal some without proof of its effects generated interest for the study of consumption of such ergogenic goers by academies of Bauru/SP; objective was also to assess whether the Physical Education professionals are prepared to guide properly, such as the use of these goers ergogenic. To this end, a questionnaire specific to each category was used, to be answered voluntarily and anonymously, with closed and open questions divided into two parts: one for socio demographic characterization and another in which were discussed issues regarding the use/orientation ergogenic. The research involved a sample of 12 academies and 205 attendees, including 152 men (74.15%) and 53 (25.85) women. Among men, 61.18% (n=93) did use ergogenic(s) food(s), while among women, this percentage was 33.96% (n=18). Regarding the use of hormonal resources, only 4.61% (n=7) of men said they used; there were no cases of women using hormonal resources. Were also interviewed 19 assessors/trainers/teachers, two which fifteen (15) men and four (4) women. Most consumers of ergogenic: (1) is understood in the age group 21-30 years and the socioeconomic classification bands called B1 and B2; (2) practice bodybuilding and consumption ergogenic resources with purpose of muscular hypertrophy; (3) practicing bodybuilding for a period between 1 and 5 years, consumes ergogenic(s) for a period less than one year, and perhaps the most significant event, starts the consumption of ergogenic(s) in a period of less than one year after starting the practice of bodybuilding, and that there are consumers who start consuming ergogenic as soon begin the practice of bodybuilding; (4) has as its main source of indication for the use of ergogenic, the gym instructor, among which, some respondents reported...
