Neural mechanisms of non-pharmacological interventions in patients with mild cognitive impairment and Alzheimer's disease: An ALE meta-analysis.

Non-pharmacologic interventions are effective for persons showing mild cognitive impairment (MCI) and Alzheimer's disease (AD). We used activation likelihood estimation (ALE) meta-analysis to systematically quantify the results of 19 neuroimaging studies in order to identify brain regions in which patients showed stable increases or decreases in activation after interventions. We also tested the moderating effects of disease stage (MCI vs.

Contextual modulation of the red-attractiveness effect: Differences in affiliation and competitive settings.

Color is not just about aesthetics but also communicates specific information and has important implications for psychological functioning. It has been shown that the color red enhances perceived attractiveness when evaluating the opposite sex, which we call the red-attractiveness effect. However, few studies have attached importance to the social context in which attractiveness ratings are made, which means that the red-attractiveness effect is rarely explained by analyzing the role of social context.

New flavonoid glycosides from Sedum aizoon L.

Five new flavonoid glucosides (3-4, 10-12) and a new phenolic derivative (5), together with eight known compounds including three flavonoid glucosides (6-8), three phenolic compounds (1-2, 9) and two megastigmane glucosides (13, 14), were isolated from the ethanol extract of the aerial part of Sedum aizoon L. Among them, compounds 9, 13 and 14 were isolated and identified from this genus for the first time. The structures of compounds were elucidated on the basis of 1D and 2D NMR (HSQC, HMBC and COSY) spectra and the HR-ESI-MS data.

Effects of five oleanolic acid triterpenoid saponins from the rhizome of Anemone raddeana on stimulus-induced superoxide generation, phosphorylation of proteins and translocation of cytosolic compounds to cell membrane in human neutrophils.

Five oleanolic acid triterpenoid saponins (OTS-1, 2, 3, 4 and 5) were isolated from the rhizome of Anemone raddeana. The effect of these triterpenoid saponins on stimulus-induced superoxide generation in human neutrophils was assayed by measuring the reduction of ferricytochrome c using a dual-beam spectrophotometer. The phosphorylation of neutrophil proteins, and translocation of p67(phox), p47(phox) and Rac to plasma membrane were investigated using specific monoclonal antibodies.
