Avaliação do estado nutricional relativo ao zinco de um grupo de estudantes universitárias da Universidade de São Paulo / Evaluation of zinc nutritional status of a group of university students from the University of São Paulo

Flores, Luz Mérida Rondán 09 June 2006 (has links)
Pesquisas experimentais e clinicas recentes têm reforçado a importância do zinco na nutrição humana, no entanto, grupos populacionais sadios podem apresentar deficiência deste micronutriente. Este trabalho avaliou o estado nutricional de um grupo de estudantes universitárias da Universidade de São Paulo em relação ao zinco. Participaram trinta e oito estudantes de sexo feminino, com faixa etária de 19 a 31 anos, que não fizeram uso de suplemento vitamínico mineral contendo zinco. A média de IMC das participantes foi de 20,8. O consumo alimentar, avaliado por meio de três registros alimentares e analisado pelo programa Virtual Nutri (1.0), demonstrou que o consumo energético médio foi cerca de 1735,2 ± 132,9 kcal, a distribuição dos macronutrientes foi cerca de 62,7% de carboidratos, 11,4% de proteína e 26% de lipídeos. A ingestão média de zinco foi de 6,9 ±1,5 mg/dia. A concentração plasmática de zinco foi de 81,17 ± 14,7 µg/dL e a eritrocitária foi de 41,4 ± 8,5 µgZn/gHb. Na urina de 24 horas as médias de concentração foram 271,78 ± 175 µg/ dia. A atividade da CuZn-SOD foi de 1110,91 ± 310 U/gHb. Por estes resultados observou-se que a distribuição dos macronutrientes encontra-se adequada às recomendações, entretanto com baixo valor energético e a ingestão de zinco apresenta-se insuficiente. Com relação aos valores sanguíneos do mineral embora a média esteja dentro dos valores de normalidade, cerca de 32% apresentaram valores abaixo de 75 µg/dL, o mesmo ocorrendo em relação ao zinco eritrocitário, onde 52,6% apresentavam valores abaixo de 40 µgZn/gHb. O zinco urinário também for baixo para 65,8% das estudantes. Houve correlação entre os valores de ingestão do zinco e sua concentração sangüínea. A atividade da CuZn-SOD apresentou correlação com o zinco no plasma. De acordo com estes resultados observa-se que a maioria das participantes deste estudo estava mantendo a homeostase em relação a este mineral, entretanto com baixas reservas e algumas delas em estado de deficiência. / Recent experimental and clinical researches are emphasizing the importance of the zinc in the human nutrition; yet, populational groups may present deficiency of this nutrient. This work evaluated the nutritional status of a group of the University of Sao Paulo students, in relation to the zinc. Thirty-eight students participated in the study, all female, aged from 19 to 31 years, which made use of vitaminic-mineral supplement containing zinc. The average IMC of the participants was 20,8. The alimentary consumption, evaluated by means of three alimentary registers, analyzed by the software Virtual Nutri (1.0), demonstrated that the mean energetic consumption was of 1735,2 ± 132,9 kcal, the macronutrient distribution was of 62,7% of carbohydrates, 11,4% of proteins and 26% of lipids. The ingestion of zinc was of 6,9 ±1,5 mg/day in average. The plasmatic concentration of zinc was of 81,17 ± 14,7 µg/dL and erythrocytary concentration was of 41,4 ± 8,5 µgZn/gHb. In the 24 hour urine the mean concentrations were of 271,78 ± 175 µg/ day. The activity of CuZn-SOD was of 1110,91 ± 310 U/gHb. From these results, it could be observed that the macronutrient distribution agreed with the recommendations, however with low energetic value and insufficient zinc ingestion. With relation to the blood mineral values, although the average were positioned within a normal range, about 32% of the patients presented values lower than 75 µg/dL, the same happening with the \"erythrocytary\" zinc, where 52,6% presented values lower than 40 µgZn/gHb. The zinc in the urine was, as well, low for 65,8% of the students. There was correlation between the ingestion of zinc and its blood concentration values. The activity of the CuZn-SOD presented correlation with zinc in the plasma. According to these results, it could be concluded that the majority of the participants in the study was keeping the \"homeostasis\" in relation to this mineral, even so with low supplies and, in certain cases, with deficiency.

Desarrollo de procedimientos aplicables a la evaluación del estado ecológico de las masas de agua costeras, sensu Directiva Marco del Agua

Guinda Salsamendi, Xabier 26 May 2008 (has links)
En la presente tesis doctoral se desarrollan una serie de procedimientos para evaluar el estado de los diversos componentes bióticos (fitoplancton, macroalgas, invertebrados bentónicos) y abióticos (calidad fisicoquímica de las aguas) del medio marino en relación a la incidencia humana sobre el mismo. El objetivo de dichos procedimientos es dar respuesta a las exigencias establecidas en la Directiva Marco del Agua (Directiva 2000/60/CE) en lo que respecta a la evaluación del estado ecológico de las masas de agua costeras. En este sentido, además de ampliar el conocimiento existente sobre las características fisicoquímicas y biológicas de las masas de agua costeras de Cantabria, constituye una importante aportación tanto desde el punto de vista científico como desde el punto de vista de la gestión. Entre las contribuciones más destacadas de esta tesis cabría mencionar el desarrollo del Índice de Calidad de Fondos Rocosos (CFR) para la valoración de las comunidades de macroalgas costeras. / In this PhD. Thesis, several procedures are developed to assess human influence on the status of the marine environment biotic (phytoplankton, macroalgae, benthic invertebrates) and abiotic (physicochemical quality of water) components. The purpose of these approaches is to meet the requirements of the Water Framework Directive (2000/60/EC) regarding the ecological status assessment of coastal water bodies.In this sense, besides increasing the existing knowledge on the physicochemical and biological characteristics of the Cantabrian coastal water bodies, it provides an important contribution both from a scientific and a management point of view. One of the most outstanding contributions of this thesis is the development of the Quality of Rocky Bottoms Index (CFR) for the assessment of coastal macroalgae communities.

Detekce prvotních příznaků Alzheimerovy nemoci blízkou osobou nemocného / The detection of the first symptoms of Alzheimer's disease be the parient's close person.

Krynská, Martina January 2015 (has links)
The dissertation thesis focuses on the topic of construction of new questionnaire, which is developed from four already existing questionnaires of activities of daily living. This new questionnaire summarizes strengths of those four and submits only those activities, which are affected at the early stage of Alzheimer's dementia. The topic is introduced in the broad context of social sciences, medical science and also submits the practical issues, considering effects of Alzheimer's disease to life of patient and his closest ones. New questionnaire, which is the result of empirical research, is based on correlation analysis of three commonly used screening cognitive tests and four questionnaires which evaluate activities of daily life, which are, used as best practice in the Counseling Center for Memory Disorders Clinic of Neurology of Faculty Hospital Kralovske Vinohrady in Prague. The research sample consists of patiens, who are affected with Alzheimer's disease already. That means, that the new questionnaire can be used as a tool for those, who are the patient's closest ones for purpose of screening and reviewing abilities of daily living over time. The questionnaire also presents comprehensively compiled a list of activities of daily living which Alzheimer's disease affects in early stage and this list...
