Desenvolvimento psicossocial e ansiedades nos jovens

Este estudo, baseado na perspectiva do desenvolvimento psicossocial de Erikson, teve como principal objectivo estudar a relação entre as diferentes tarefas desenvolvimentais e a ansiedade nos jovens. Na presente investigação foi utilizada uma amostra de 511 jovens portugueses, com idades compreendidas entre os 17 e os 26 anos, que frequentavam diferentes cursos universitários em estabelecimentos de ensino superior da área metropolitana do Porto. De modo geral, verifica-se que a uma resolução das tarefas psicossociais de forma construtiva corresponde uma menor tendência para a ansiedade. Relativamente ao género, registam-se efeitos significativos nos medos, pensamentos obsessivos e comportamentos compulsivos e nos estádios do desenvolvimento psicossocial. Verifica-se que o género feminino assume médias mais elevadas na maior parte dos medos e o género masculino nas características obsessivo- compulsivas. O efeito do género nas diferentes tarefas psicossociais só se mostra significativo para a confiança vs. desconfiança em que as raparigas apresentam médias mais baixas comparativamente aos rapazes e médias mais elevadas na tarefa da indústria vs. inferioridade.This research, based on the Erikson’s psychosocial development perspective, has as its fundamental goal to study the relations between developmental psychosocial tasks and anxiety in young people. In this study we used a sample of 511 Portuguese young people, with ages between 17 and 26 years, which attended several higher education courses in the Porto area. Globally, results show that a constructive resolution of psychosocial tasks corresponds to a smaller tendency for anxiety. Results also allow the understanding of the specific contribution each stage has concerning the development of different anxious structures. As for gender, results indicate the presence of significant effects for fears, obsessive thoughts and compulsive behaviours, as well as for psychosocial developmental stages.info:eu-repo/semantics/publishedVersio

Evaluación de la adherencia al tratamiento antihipertensivo en pacientes de la Unidad de Salud Cocalzinho Goiás

A prevalência estimada de hipertensão, no Brasil, atualmente é de 35% da população acima de 40 anos. Em 2003, no Brasil, 37% dos óbitos foram decorrentes de doenças cardiovasculares, e a principal causa de morte foi o AVC. A hipertensão arterial não controlada é responsável por um grande ônus social e econômico à população. No SUS, as doenças cardiovasculares provocou 1.150.000 das internações/ano, com um custo aproximado de 475 milhões de reais. O presente estudo tem o objetivo de verificar o nível de adesão ao tratamento medicamentoso anti-hipertensivo e fazer uma análise situacional dos pacientes hipertensos do município de Cocalzinho de Goiás. É um estudo do tipo transversal com levantamento de dados e aplicação de questionário. O levantamento foi realizado nos meses de junho e julho de 2010, com os pacientes hipertensos cadastrados no programa Hiperdia no município de Cocalzinho de Goiás. O estudo mostrou uma prevalência do sexo feminino (69,32%), com predomínio do grupo de idade entre 61 a 70 anos (34,97%), com baixa escolaridade (67,18%), e com 56,14% de não adesão ao tratamento farmacológico. A baixa adesão está relacionada à baixa escolaridade. Existe uma carência de atendimento mais efetivo e individualizado de pacientes hipertensos, de responsabilidade da ESF. _________________________________________________________________________________ ABSTRACTThe estimated prevalence of hypertension in Brazil is currently 35% of the population over 40 years. Brazil is among the few countries whose first cause of death is cerebro vascular accident (CVA) and not of ischemic heart disease (CHD). In 2003, Brazil, 37% of deaths were due to cardiovascular diseases. In the SUS, cardiovascular diseases account for 1.15 million hospitalizations per year, with an approximate cost of 475 million reais. The uncontrolled hypertension is responsible for a great social and economic burden to the population. This study intends toconduct a situational analysis of hypertensive patients in the city of Cocalzinho to verifythe level of medication adherence. This is across-sectional study with data collectionand questionnaire. The survey was conducted during June 2010 and July 2010, with hypertensive patients enrolled in the program Hiperdia in the municipality of Cocalzinho. The study showed a predominantly female population (69.32%), aged 61 to 70 (34.97%),low education (67.18%), which increased the illiterate totaled 91.11%, with 56.14% of non-medication adherence. The work performed allowed to relate to non-adherence to low education. _________________________________________________________________________________ RESUMENLa prevalencia estimada de la hipertensión en Brasil es actualmente el 35% de la población mayor de 40 años.

Alleviation of salt stress using exogenous proline on a citrus cell line

Salinity constitutes an important abiotic problem since ancient times, world-wide, for it leads to a decrease in productivity of crops with agronomic value. Under salt stress conditions, plant cells develop strategies to cope with Na+ and Cl-, including exclusion and compartmentalisation, induction of antioxidant enzymatic systems and compatible solutes accumulation, such as proline. The precise function of this osmolyte still remains unclear. Proline may act on osmotic adjustment, as a free radical scavenger, protecting enzymes and avoiding DNA damages. It has been also suggested the role of proline in prevention of lipid peroxidation and as a signalling/regulatory molecule. A salt-sensitive Citrus sinensis ‘Valencia late’ cell line has a smaller growth rate and accumulates proline in the presence of NaCl (>200 mM). The addition of external proline to this cell line was evaluated in terms of cell metabolism. A positive influence on the relieve of salt stress symptoms due to the presence of exogenous proline 5 mM and 100 mM NaCl was obtained, with increased growth of this salt sensitive citrus cell line.info:eu-repo/semantics/publishedVersio

Saline stress and cell toxicity evaluation using suspended plant cell cultures of horticultural crops grown in a bioreactor

Crop salt damage consists, usually, of leaf burn and defoliation, and it is associated with accumulation of toxic levels of sodium and/or chloride in leaf cells (Storey and Walker, 1999). The cell and tissue culture are simple biological systems that offer a direct approach to the metabolic changes. The plant cell growth in a controlled environment, as a bioreactor, is a unique tool for cell ion transport studies. Cell suspension culture of citrus cell line was exposed to a medium containing different sodium chloride concentrations (0mM, 42.7mM and 85.5mM). The growth profile of control cells (absence of NaCl) and 85.5mM cells were similar. The lack of inhibition of biomass accumulation, of all tested saline conditions clearly showed that the level of NaCl concentration used was not toxic for the cell metabolism. Also its ability to resist to 85.5mM NaCl can be on evidence that this suspension cel culture might have salt tolerance characteristics

The performance of an aerated stirred tank reactor on VHG batch fermentations

The quest for new and renewable energy sources has greatly increased due to the depletion of fossil fuels reserves. Agro-food wastes appear as a cheap and renewable energy source that can contain great amounts of carbon to be transformed in bioethanol that can be used as additive to gasoline

Production of bioethanol from sweet potato, agro industrial wastes

One fraction of the existent petroleum is not extractable or the difficulties associated to extraction are very expensive making them unviable. This situation leads to a decrease in petroleum stocks all over the world and a resulting increment on its price, affecting in particular the transportation sector, since there is no relevant alternative to fossil petroleum

Sustainable bioethanol production using agro-industrial by-products

This work aimed to evaluate a sustainable bioethanol production by a laboratorial isolate strain of Saccharomyces cerevisiae, along with the use of agro-industrial by-products as carbon source. The effect of several carbon sources and their concentrations was studied using carob pod extract (CPE) and beet molasses (BM) and compared with glucose and sucrose as conventional carbohydrates at different concentrations, 15, 20 and 30 g/l.No significant difference was found between maximum ethanol production obtained with CPE, BM, glucose and sucrose fermentations profiles. It was obtained values of 10.65 g/l and 10.5 g/l ethanol, respectively for sucrose and CPE at 30g/l, which can be improved using higher substrate concentration
