The present study regards an applied qualitative social research (descriptive) which approaches the matter between old age and Brazilian social actions performed in social projects, aiming a qualified life and citizenship for this group of age. The objective of the study is to evaluate the contribution of Project Health and Citizenship in Old Age regarding social actions from the government directed to old age individual treatment for life quality improvement. The theoretical fundamentals of this work is, in a first moment, about old age and certain existing theories about aging process, as well as the differences and perspectives that come up throughout this process. In a second moment, some reflections are developed about the relation between life quality and leisure regarding old age, with the conception and historical rescue about these questions, as well as the evidence of leisure as an instrument of well-being feasibility and a better life quality in old age. Then the study contextualizes Brazilian government treatment to old age individuals, cutting off the Constitution of Republic from 1988 and some social attitudes taken by the government in a try to reach this specific group. Finally, the study presents the Project Health and Citizenship in Old Age , as a social program which belongs to extension activities from Federal Center of Technological Education of Rio Grande do Norte (CEFET-RN), which aims old age treatment and their citizenship and life quality. After the application of a semi-structured interview using the technique of Analysis of content for the Analysis and Discussion of Results, it is possible to conclude that the Project Health and Citizenship in Old Age fulfils its objective regarding contribution, through offered leisure activities, for old age well-being and life quality improvement. Hence, on this regard, it is possible to observe the importance and value of government actions, social projects and programs assisting old age individuals, for they are able to provide this group the opportunity to live out activities that allow their citizenship and socialization, regarding well-being and life quality improvement.

This thesis concerns the study of the city and impacts that will be caused in its structure due to the aging process of the human society, mainly in Brazil. The most important focus will be those related to problems of accessibility, leisure, housing, health and labor, issues that most affect people over 60 years of age. Beyond the analysis of inherent problems to the subject, proposals will be made for urban intervention that the cities become more suitable for the living of the elderly. To support this study, a review of different theories about the city was carried out, then a panel about the presence of the elderly in society, including Brazil, and in the cities, aiming at a vision, as broad as possible, on how the elderly were treated throughout history. In order to establish paradigms and parameters in the approach to the subject, a series of systematic observations on the urban space in different cities proceeded, in Brazil and abroad, with works aiming the inclusion of the elderly in urban areas, such as Amsterdam, Barcelona, Brasilia, Luanda and Rio de Janeiro, a city considered by the UN as physical and territorial urban laboratory suitable for the elderly. From there we tried to obtain, in addition to literature and observation of other countries experiences, the conduct of field research and official standards analysis, the theoretical basis for establishing guidelines on how to plan and design a more appropriate urban space for the elderly

Reactive oxygen species (ROS) are produced by aerobic metabolism and react with biomolecules, such as lipids, proteins and DNA. In high concentration, they lead to oxidative stress. Among ROS, singlet oxygen (1O2) is one of the main ROS involved in oxidative stress and is one of the most reactive forms of molecular oxygen. The exposure of some dyes, such as methylene blue (MB) to light (MB+VL), is able to generate 1O2 and it is the principle involved in photodynamic therapy (PDT). 1O2 e other ROS have caused toxic and carcinogenic effects and have been associated with ageing, neurodegenerative diseases and cancer. Oxidative DNA damage is mainly repaired by base excision repair (BER) pathway. However, recent studies have observed the involvement of nucleotide excision repair (NER) factors in the repair of this type of injury. One of these factors is the Xeroderma Pigmentosum Complementation Group A (XPA) protein, which acts with other proteins in DNA damage recognition and in the recruitment of other repair factors. Moreover, oxidative agents such as 1O2 can induce gene expression. In this context, this study aimed at evaluating the response of XPA-deficient cells after treatment with photosensitized MB. For this purpose, we analyzed the cell viability and occurrence of oxidative DNA damage in cells lines proficient and deficient in XPA after treatment with MB+VL, and evaluated the expression of this enzyme in proficient and complemented cells. Our results indicate an increased resistance to treatment of complemented cells and a higher level of oxidative damage in the deficient cell lines. Furthermore, the treatment was able to modulate the XPA expression up to 24 hours later. These results indicate a direct evidence for the involvement of NER enzymes in the repair of oxidative damage. Besides, a better understanding of the effects of PDT on the induction of gene expression could be provided

The red ceramic industry is recognized as of major importance in Piauí State. The State capital, Teresina, is the greatest producer of this material ( production about 18 million peaces), which is used mainly for masonry sealing blocks. One of the most frequent problems in this kind of products is the efflorescence. This work has the main objective of studying the influence of gypsum addition on non-glazed tiles, by using the local industry production standards. The raw materials were characterized by FRX, DRX, TGA, DTA and AD. Extruded test specimens were made with the addition of 1, 3 and 5% of gypsum in the ceramic paste, burned at 850oC, 950oC and 1050oC and submitted to further technological tests and microestrutural analysis by the scanning electron microscope. In order to accelerate the aging of bodies of evidence, they were immersed in successive water baths and posterior drying. The reference ceramic paste showed tendency to efflorescence formation after drying and consolidated efflorescence after burning, but no affecting the technological results

Structural changes in waste for zeolites synthesis are subject of many studies carried out in the synthesis of molecular sieves. These materials are named molecular sieves because they have well defined pore sizes and they have the capacity of select molecules by its size. In this work, it was studied the synthesis processes of two types of molecular sieves: pillared acid clays using as starting material one natural montmorillonite clay and the synthesis of zeolites from a silico-aluminous residue. This residue is a byproduct of the extraction of lithium -spodumene. The preparation of pillared acid clays was performed in two steps: 1° acid treatment of clay samples (time and temperature studies) and 2°pilarization of them with Al13 (Keggin ion). The temperature and acid concentration affect the removal of cations in the structure and porosity of the material obtained. The analysis of X-ray diffraction (XRD) and infrared spectroscopy (IR), showed that increasing the severity of the acid treatment compromises the structural material. Also the pore size distribution is approximately uniform. Despite presenting a structural disorganization, the samples were pillared. As evidenced by XRD increasing the basal spacing, specific area and uniform porosity by adsorption of N2. Regarding the microporous molecular sieves were synthesized zeolites A and NaP1 from a silico-aluminous residue, a byproduct of extracting lithium. The temperature and time of agitation during the synthesis were the most important factors for obtaining zeolite A. The aging of the gel and the highest crystallization time promoted the formation of zeolite NaP1 using a Si / Al ratio = 3.2

In recent decades have seen a sharp growth in the study area of nanoscience and nanotechnology and is included in this area, the study of nanocomposites with self-cleaning properties. Since titanium dioxide (TiO2) has high photocatalytic activity and also antimicrobial, self-cleaning surfaces in your application has been explored. In this study a comparison was made between two synthesis routes to obtain TiO2 nanoparticles by hydrothermal method assisted by microwave. And after analysis of XRD and SEM was considered the best material for use in nanocomposites. It was deposited nanocomposite film of poly (dimethyl siloxane) (PDMS) with 0.5, 1, 1.5 and 2% by weight of nanoparticles of titanium dioxide (TiO2) by the spraying method. The nanocomposite was diluted with hexane and the suspension was deposited onto glass substrate, followed by curing in an oven with forced air circulation. The photocatalytic activity of the nanocomposite impregnated with methylene blue was evaluated by UV- vis spectroscopy from the intensity variation of absorption main peak at 660nm with time of exposure to the UV chamber. Changes in the contact angle and microhardness were analyzed before and after UV aging test. The effect of ultraviolet radiation on the chemical structure of the PDMS matrix was evaluated by spectrophotometry Fourier transform infrared (FTIR).The results indicated that the addition of TiO2 nanoparticles in the coating PDMS gave high photocatalytic activity in the decomposition of methylene blue, an important characteristic for the development of self-cleaning coatings

The aging process if characterizes for a complex events network, from multidimensional nature, that encloses biological, social, psychic and functional aspects. The alteration of one or more aspects can speed up the aging process, anticipating limitations and until the death in the aged. For an adjusted confrontation of this question is necessary an interdisciplinary vision, in which the some areas of the knowledge can interact and with this to intervenes of the best possible form. Then, information derived from studies of aspects related to incidence, morbidity-mortality and transition patterns, involved in the health-illness process can more accurately identify risk groups thereby establishing links between social factors, illness, incapacity and death. Thus, this study aimed to identify, by a multidimensional vision, the risk factors of mortality in a coorth of elderly in a city in the interior of the state of Rio Grande do Norte (RN), Brazil. A prospective study carried out in Santa Cruz RN, where 310 elderly were randomly selected to form a baseline. The follow-up was 53 months. The predictive variables were divided into sociodemographic, physical health, neuropsychiatric and functional capacity. The statistical analysis carried out by bivariate analysis, survival analysis, followed by binary logistic regression and Cox regression, in the multivariate analysis, considering significant levels p < 0.05 and confidence interval (CI) of 95%. A total of 60 (19.3%) elderly died during the follow-up, where cardiovascular disease was the main cause. The survival was approximately 24.8 months. The study of general survival showed, at 12, 24, 36, and 48 months of observation, a survival rate of 97%, 54%, 31%, and 5% respectively, with a statistical difference in survival only observed for the variables of cognitive function and Basic Activities of Daily Living. In the logistic regression analysis, the risk factors identified were cognitive deficits (OR = 8.74), poor perception of health (OR = 3.89) and dependence for Basic Activities of Daily Living (OR = 3.96). In the Cox analysis, as well as dependence for Basic Activities of Daily Living (HR = 3.17), cognitive deficit (HR = 4.30) and stroke (CVA) (HR = 3.49) continued as independent risk factors for death. The risk factors found in the study can be interpreted as the primary predictors for death among elderly members of the community. Therefore, improvements in health conditions, with actions towards sustaining an autonomous life with special attention for elderly with cognitive impairment, could mean additional healthy quality of life, resulting in the reduction of premature mortality in this population

The imprecision of the frontier that separates those cognitive deficits inherent to the human physiological aging process from those which represent the early signs of nervous system degenerative pathologies ,very prevalent among the elderly, has brought attention to the need of studies aiming to establish clinical and/or laboratorial criteria to allow this differentiation. Elderly people living in poor and developing countries are frequently exposed to precarious socioeconomic conditions which facilitate the development of an array of pathologies which have metabolic and nutritional dysfunctions as the established or proposed etiological agents. The levels of certain micronutrients, such as the vitamins B12 and B9 (folic acid), and of some intermediary metabolites, such as homocysteine are being thought of as etiological factors and/or as biological markers of a group of alterations which affect the normal functioning of the nervous system with important reflexes upon cognitive performance. This study aims to investigate the influence of homocysteine, B12 vitamin and folic acid levels on the cognitive performance of the low income elderly population. This transversal study took place in Natal, Rio Grande do Norte State, Brazil, and involved 205 dwelling elderly people, users of the Programa de Saúde da Família, a public healthcare program, maintained by the city s health authorities. A multidimensional questionnaire was used to assess the socio-demographic aspects and the overall health and nutrition conditions. The cognitive performance was measured by the use of the Portuguese version of the Mini Mental State Exam (MMSE). The serum levels of homocysteine, B12 vitamin and folic acid were determined by chemiluminescence. The association between the socio-demographic and serum levels of Hcy, B12 vitamin and folic acid was determined by multiple linear regression. Serum levels higher than 13.5 μmol/l, indicative of hyperhomocysteinemia (HHcy), were found on 25.4% of the sample, being more prevalent in men (p<0.05). Deficitary levels of folic acid (<5ng/mol) and of B12 vitamin (<193 pg/ml) were found on 3.9% and 10.2% of the sample respectively. A negative correlation was found between cognitive performance with both age and HHcy and a positive correlation was found between cognitive performance and schooling. The isolated HHcy R2 values were an explanation to only 4% of the variance of the MMSE scores. However, when associated with schooling and age, this model explains about 25% of this association

Changes introduced by cardiopulmonar and neuromuscular training on basal serum insulin-like grow factor-1 (IGF-1) and cortisol levels, functional autonomy and quality of life in elderly women The aim of this study was to compare the effects of strength and aerobic training on basal serum IGF-1 and Cortisol levels, functional autonomy (FA) and quality of life (QoL) in elderly women after 12 weeks of training. The subjects were submitted the strength training (75-85% 1-RM) with weight exercises (SG; n=12; age=66.08 ± 3,37 years; BMI=26,77 ± 3,72 kg/m2), aerobic training with aquatic exercises (AG; n=13; age=68,69 ± 4,70 years; BMI=29,19 ± 2,96 kg/m2) and control group (CG; n=10; age=68,80 ± 5,41 years; BMI=29,70 ± 2,82 kg/m2). Fasting blood was analyzed to measure basal IGF-1 and cortisol levels by chemiluminescence method. The t-Student test showed increased IGF-1 in the SG (p<0.05) for intragroup comparison. The Repeated-measure ANOVA presented increased IGF-1 (p<0.05) in the SG compared to the other two groups. There were no differences in cortisol levels. All the FA tests (GDLAM autonomy protocol) presented decreased significant in the time marked in seconds to the SG. The same results were found in the AG, except in the rise from a sitting position test. The autonomy index presented significant improvements (p<0.05) in the SG related to the AG and CG and in the AG to the CG. The SG showed increased QoL (p<0.05) (by WHOQOL-Old questionnaire) in the facet 1 (sensorial functioning) and facet 5 (death and dying). Thus, the SG obtained positive changes on IGF-1 and FA levels when compared to the AG. This suggests that strength training can indicated to decrease the effects of ageing.

A incapacidade funcional e o déficit cognitivo são condições relacionadas com o processo de envelhecimento humano. O déficit cognitivo é considerado um importante fator preditor de prejuízos funcionais em populações idosas. Este estudo teve um caráter multidisciplinar na sua elaboração e execução, contando com profissionais de distintas áreas da saúde. Trata-se de um estudo transversal que analisou a associação do desempenho cognitivo na capacidade funcional de uma amostra populacional idosa residente em Natal-RN. Foram avaliados 213 idosos pelo Questionário Multidimensional BOAS e pelo Mini-Exame do Estado Mental (MEEM). Através de análise multivariada, mediante regressão linear, os resultados apontam a idade e o nível de escolaridade como fatores associados ao desempenho cognitivo nos idosos do estudo. O modelo explicativo final elaborado através de regressão logística apresentou o desempenho cognitivo como a única variável associada à incapacidade funcional para as atividades da vida diária, mesmo quando ajustado por variáveis sócio-demográficas. A identificação dos fatores, associados ao declínio do estado funcional dos idosos que vivem na comunidade, poderá reduzir o impacto dessas condições na capacidade funcional através da aplicação de medidas preventivas voltadas para este fim

Ações promotoras de saúde e independência para pessoas idosas são indispensáveis. Compreender essa construção no cotidiano da provisão dos cuidados talvez estimule o desenvolvimento de capacitações ao bem estar nesta população. O objetivo deste estudo foi Identificar a repercussão da provisão do cuidado formal em saúde bucal na percepção de senescentes. Desenvolvemos uma pesquisa de base qualitativa com abordagem fenomenológica, onde realizamos entrevistas semiestruturadas e individuais com 30 pessoas de idade superior a 50 anos (22 mulheres e 08 homens), em um Centro de Convivência na cidade de Natal/Rio Grande do Norte, no nordeste do Brasil. Os relatos obtidos foram analisados em cinco estágios: transcrição dos discursos sem preocupação interpretativa; limpeza de erros linguísticos e repetições; leitura repetitiva e exaustiva para apreensão do sentido das informações coletadas; seleção das unidades significativas dos discursos, correspondendo aos trechos relevantes no horizonte do fenômeno em estudo; e compreensão da ideografia elaborada pelos participantes por grupos temáticos simbólicos. Assim, identificamos as essências temáticas de: determinante social e iniquidade em saúde bucal; e provisão de cuidados de saúde bucal e mal-estar físico, mental e social. Concluímos que a prestação de cuidados agregando abordagem humanístico-ética pode levar a vivências dignificantes no processo de envelhecimento, destacadamente quando estimula a promoção da segurança pessoal. O âmago desse trabalho descortina uma vertente multidisciplinar que perpassa a saúde, a educação e a ética

Introdução/objetivos: A avaliação do estado de saúde de idosos institucionalizados é considerada prática essencial à promoção e recuperação da sua saúde, a qual deve incluir a investigação de aspectos multidimensionais e multidisciplinares relacionados ao envelhecimento saudável. O estudo objetivou avaliar as condições de saúde dos idosos residentes em instituições de longa permanência (ILPI) do município de Natal RN. Métodos: Trata-se de um estudo descritivo, longitudinal, envolvendo seis ILPI filantrópicas, com uma população de 243 idosos. A coleta de dados se deu por meio de entrevistas com os idosos nas instituições mediante a aplicação de um questionário com informações sócio demográficas, saúde e institucionalização, além de várias facetas multidisciplinares que envolvem a escala de avaliação cognitiva (Mini Exame do Estado Mental); o índex de KATZ, para avaliação das atividades da vida diária e uma análise do estado nutricional com questões antropométricas (peso, estatura, circunferência abdominal) e Índice de Massa Corpórea. Participaram do estudo todos os idosos com idade igual ou superior a 60 anos, que aceitaram responder a entrevista e assinaram o Termo de Consentimento Livre e Esclarecido e/ou a impressão datiloscópica. O projeto foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal do Rio Grande do Norte, sob parecer n° 164/2011. Resultados: Os participantes do estudo incluem 243 idosos, sendo a maioria mulheres (172 = 70,7%), com média de idade de 79 ± 9,44 anos. 124 idosos são solteiros (51,0%) e 66 viúvos (27,0%). A prática de atividades físicas não é rotina nas instituições, onde a maioria dos idosos (82,7%; n = 201) não realiza nenhum tipo de atividade. 78% dos idosos (n = 192) chegou a instituição sendo levados por familiares, enquanto que apenas 18% (n = 44 idosos) por vontade própria e 4% (n = 7 idosos) não souberam responder. Quanto aos aspectos cognitivos, identificou-se que 64,2% dos idosos (n = 156) apresentaram alterações significativas dentro da pontuação dos escores com restrições em responder aos demais questionamentos durante a entrevista por apresentarem limitações cognitivas e/ou dificuldades senso perceptivas.Conclusão: O presente estudo evidenciou alterações cognitivas na maioria dos idosos institucionalizados impossibilitando-os a continuidade da realização da avaliação global da saúde. A identificação correta da perda cognitiva em idosos é de suma importância para a equipe de saúde a fim de promover a detecção precoce de alterações cognitivas e a adoção de tratamento adequado, no sentido de contribuir para uma melhor qualidade de vida desta população

Physiological changes induced by the aging process is dynamic and progressive, reducing the adaptability and independence of older people and may be influenced by genetic and environmental factors. Thus the aim of this thesis was to investigate the association between polymorphism of the ACE gene ID and the phenotypes of muscular strength and blood pressure of 62 elderly Brazilian (67.35 ± 5.66 years) during a 16-week program of supervised training. The elderly women were stratified by age, with the group 1 (G1, n = 34) <70 years and group 2 (G2 n = 28) ≥ 70 years, and in three groups by ACE, ACE-II (n = 8) ACE- DD (n = 35) and ACE-ID (n = 19). The level of muscle strength was evaluated by the method of maximum repetitions and measures of blood pressure (BP) were measured before and after training (PAPré1 and PAPós1) and before and after each training session (PAPre2 and PAPós2), in place of training. DNA samples were isolated from peripheral blood leukocytes polymorphism and insertion / deletion (ID) of the ACE gene (rs1800795) was genotyped by polymerase chain reaction (PCR) plus PCR-confirmatory. The genotype distribution of the polymorphism ID attended the prerogatives of Hardy-Weitíherg. There was variation in power levels before and after training and the age between groups (t-test) and the ACE polymorphism (ANOVA) (p <0.05). Depending on the results it was concluded that resistance training helps to reduce SBP and increased muscle strength of upper and lower limbs when considering the age and ACE polymorphism. In this study the Elderly carriers of the D allele were more reactive to changes in BP resistance training. This study was multidisciplinary project involving researchers in the areas Medical, Physical Education, Pharmacy, Nutrition, Gerontology and Statistics. This fulfilled the requirements of the multidisciplinary Graduate Program in Health Sciences
