Influencia de la actividad física en la enfermedad de Alzheimer: un caso clínico

Alzheimer's dementia (AD) is a neurodegenerative disorder that causes motor and cognitive decline. The aim of this study was to analyze the influence of a specific physical activity program on the cognitive, depressive symptoms and functional capacity of patients with diagnosis of probable AD. The subject, a 79-year old woman, participated in this program for three months, with 50 min sessions three times a week. The instruments used were the Cambridge Cognitive Examination; the Geriatric Depression Scale; and the Battery of the American Alliance for Health Physical Education, Recreation and Dance. The results in relationship with the depressive symptoms and functional capacity were significantly positive. There were no changes in regards to the patient's cognitive functions. In conclusion, this physical activity program seems to be an important part of the treatment for patients with AD, as it improves the functional capacity and also stimulates cognitive tasks. © 2008 Asociación Española de Fisioterapeutas.

Eugenia dysenterica DC: Actividad antioxidante, Perfil de ácidos grasos y determinación de tocoferoles

This work aimed to characterize the proximate composition, antioxidant activity and fatty acids profile and tocopherol composition of the oil from Eugenia dysenterica DC seeds. To obtain the extract, the dehydrated and triturated seeds were extracted with ethyl alcohol for 30 minutes, at a proportion of 1:3 of seeds:ethyl alcohol, under continuous agitation at room temperature. Afterwards, the mixture was filtered and the supernatant was dehydrated at 40°C in order to determine by direct weighing the dry matter yield of the extract. The cagaita seeds showed to be an important source of total carbohydrates, had relevant antioxidant activity and a high content of total phenolic compounds. In comparison to other oils and fats, cagaita seeds oil do not constitutes a good source of tocopherols.

Actividad antioxidante y perfil de ácidos grasos de las semillas de jabuticaba (Myrciaria cauliflora Berg)

Numerous natural compounds found in fruits, grains and vegetables have antioxidant activity. This work aimed to characterize jabuticaba seeds (Myrciaria cauliflora Berg) by proximate composition, antioxidant activity and fatty acids profile of their extracted oil. To obtain the extract, the dehydrated and triturated seeds were extracted with ethyl alcohol for 30 min, at a proportion of 1:3 of seeds:ethyl alcohol, under continuous agitation, at room temperature. Afterwards, the mixture was filtered and the supernatant dehydrated at 40 °C aiming to determine, by direct weighing, the extract's dry matter yield. According to the results, the jabuticaba seeds are an important source of total carbohydrates, and also presented relevant antioxidant activity. In the jabuticaba seeds oil, a significant percentage of polyunsaturated fatty acids stood out, with linoleic and α-linolenic being the main component, essentials fatty acids.
