Association of memory and cognition in Alzheimer's disease with volumetric estimates of temporal lobe structures.

The hypothesis that explicit memory impairment in Alzheimer's disease (AD) depends in part on hippocampal formation atrophy was tested in 47 persons with AD. Volumes of the hippocampal formation, parahippocampal gyrus, and temporal neocortex (excluding the hippocampal formation, amygdala, and parahippocampal gyrus) were estimated by reconstruction of magnetic resonance images. Tests of explicit memory, language, and constructional praxis were administered. Psychometric-volumetric associations were evaluated in regression analyses controlling for age, gender, education, and intracranial volume. Hippocampal formation volume was associated with a delayed-recall measure but not with immediate recall: temporal neocortical volume was correlated with performance on measures of language and constructional praxis. The results suggest that patterns of mnemonic and cognitive impairment in AD are due in part to differences in the distribution of pathology in the temporal lobe.

An alternative approach for calculating/measuring fundamental powers based on wavelet packet transform and its frequency sensitivity analysis

Power and harmonic analysis are among the most important topics of power systems. These analyses usually are based on Fourier transform method. In this study, as a novel approximation, the accuracy of proposed method using wavelet packet transform for fundamental active-reactive-apparent powers, displacement power factor are pointed out with computer simulations. Moreover, frequency sensitivity of the wavelet packet based power analysis, any study concerned with it is not found in the literature up to now, is carried out in comparison with the classic Fourier-based analysis. The results show the supremacy of the proposed wavelet packet-based approach over the Fourier-based approach when the frequency variation is concerned.     

Antioxidant capacity and functionality of oleaster (Elaeagnus angustifolia L.) flour and crust in a new kind of fruity ice cream

In this study, the influence of milled crust and flour from oleaster (Elaeagnus angustifolia L.) separately added at different levels (1%, 2% and 3%) on the physical, chemical, sensory, colour properties and antioxidant properties of ice creams were investigated. The increment of crust and flour level caused an increase of dry matter, acidity, viscosity, first dripping, complete melting and vitamin C content. Flour increased overrun values in ice cream. Our results indicated that lyophilised oleaster extracts contain remarkable phenolic compounds. It was observed that lyophilised oleaster extracts exhibited a moderate in vitro antioxidant capacity. The addition of oleaster flour and crust positively affected sensory properties. The sensory results showed that ice cream containing 2% oleaster flour was the highest scored by the panellists. Oleaster flour and crust increased the sweetness of ice cream samples. These results showed that considerable nutritive and functional improvement could be attained by the addition of oleaster flour to ice cream formulation so that it could be used as natural antioxidants in ice cream as a source of flavour with complacency.     

Seasonal changes in the total fatty acid composition of Vimba, Vimbavimba tenella (Nordmann, 1840) in Eğirdir Lake,Turkey

Total fatty acid compositions and its seasonal variations in Vimba, Vimba vimba tenella (Nordmann, 1840) in E?irdir Lake, which is the second largest freshwater lake in Turkey, were investigated by a gas chromatographic method. Twenty seven different fatty acids were determined in the composition of Vimba vimba tenella. Monounsaturated fatty acids (MUFAs) were found to be in higher amounts than saturated fatty acids (SFAs) and polyunsaturated fatty acids (PUFAs) in all seasons. Oleic acid (C18:1 n9) was the major MUFA in all seasons. Palmitic acid (C16:0) was identified as the major SFA in all four seasons. Arachidonic acid (C20:4 n6), docosahexaenoic acid (C22:6 n3), linoleic acid (C18:2 n6), and eicosapentaenoic acid (C20:5 n3) were at the highest levels among the PUFAs. In the present study, n-3/n-6 ratios were found to be 1.4,1.5,1.2 and 1.4 in spring, summer, autumn and winter, respectively. Vimba vimba tenella may be a valuable food for human consumption in terms of fatty acids.
