Our data demonstrate that priming of human neutrophils with TNF-α promotes uric acid-mediated IL-1β secretion in the absence of microbial stimulation. These findings provide insights into the neutrophils-mediated inflammatory processes in gouty arthritis.
Background: Previous studies using magnetic resonance imaging (MRI) showed that dementia with Lewy bodies (DLB) had less atrophy in some medial temporal structures than Alzheimer’s disease (AD). However, very few studies have focused on the entorhinal cortex, which is closely related to episodic memory. We compared the degree of entorhinal cortex atrophy between the two types of dementia using the voxel-based specific regional analysis system for AD (VSRAD) targeting this region. Methods: The subjects consisted of 60 patients with DLB and 210 patients with AD. The degree of entorhinal cortex atrophy was quantified by application of the VSRAD to MRI data, and a Z score >2 was defined as significant atrophy. Results: The DLB group had significantly lower Z scores than the AD group (mean ± SD: 2.25 ± 1.10 vs. 2.85 ± 1.33, p < 0.01). The analysis of covariance with possible confounding factors as covariates also showed that Z scores were significantly lower in the DLB group than in the AD group (p < 0.01). The proportion of patients with atrophy was significantly lower in the DLB group than in the AD group (53 vs. 72%, p < 0.01). Conclusions: The present study using the VSRAD suggests that DLB shows less atrophy in the entorhinal cortex than AD.
Near-water-density structures situated posterior to the pulmonary trunk and right main pulmonary artery in patients without obvious pericardial effusion were concluded to be physiologic fluid collections in the recesses of the transverse and oblique sinuses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
