“The purpose of this study was to examine
whether mechanisms, involved during PF-6463922 cell line the maintenance of familiar movement information in memory, were influenced by the degree of familiarity of the display in which the movements were embedded. Twelve gymnasts who possessed high visual and motor familiarity with the movements employed in this study, were recruited. They were invited to retain for a short period of time familiar movements viewed previously and presented under different displays with the aim of recognizing them at a later stage. The first display was a realistic, familiar display which presented videos of movements. The second display was an unfamiliar impoverished display never experienced in every day life which Wortmannin solubility dmso showed point-light
movements. Activity during the maintenance period was considered in five frequency bands (4-8Hz, 8-10 Hz, 10-13 Hz, 13-20Hz, 20-30Hz) using a non-linear measure of functional connectivity. The results in the 13-20 Hz frequency band showed that functional connectivity was greater within the frontal and right temporal areas during the unfamiliar display (i.e., point-light maintenance condition) compared to the familiar display (i.e., video maintenance condition). Differences in functional connectivity between the two maintenance conditions in the beta frequency band are mainly discussed in the light of the process of anticipation. Subjects’ perception of the expected difficulty of the upcoming recognition task is discussed. (c) 2012 IBRO. Published by Elsevier Ltd. All rights reserved.”
“Atherosclerosis is an inflammatory disease of the arteries, else which results in major morbidity and mortality. Immune cells initiate and sustain local inflammation. Here, we focus on how dendritic cell (DC)-mediated processes might
be relevant to atherosclerosis. Although only small numbers of DCs are detected in healthy arteries, these numbers dramatically increase during atherosclerosis development. In the earliest fatty streaks, DCs are found next to the vascular endothelium. During plaque growth, new DCs are actively recruited, and their egress from the vessel wall is dampened. In the adventitia next to mature atherosclerotic lesions, tertiary lymphoid organs develop, which also contain DCs. Thus, DCs probably participate in all stages of atherosclerosis from fatty streaks to mature lesions.”
“Background First dose oral co-trimoxazole and referral are recommended for WHO-defined severe pneumonia. Difficulties with referral compliance are reported in many low-resource settings, resulting in low access to appropriate treatment. The objective in this study was to assess whether community case management by lady health workers (LHWs) with oral amoxicillin in children with severe pneumonia was equivalent to current standard of care.
