Cumulative inflammatory burden contributes to the development of carotid atherosclerosis through a synergistic interaction with conventional CV risk factors in patients with RA.
We investigated the clinical and endoscopic features of gastrointestinal lesions in adults with Henoch-Schönlein purpura (HSP) causing gastrointestinal bleeding. The study included 24 adult HSP patients with gastrointestinal hemorrhage who underwent both upper gastrointestinal endoscopy and colonoscopy. The controls were 27 adult HSP patients without gastrointestinal hemorrhage. Patients with gastrointestinal bleeding showed higher frequencies of purpura on the upper extremities and trunk, and of elevated serum C-reactive protein (CRP). The rate of concurrent lesions in both the upper and lower gastrointestinal tracts was 91.7 %. The second portion of duodenum and terminal ileum were most frequently and severely involved. Leukocytoclastic vasculitis was detected in severe lesions and was significantly associated with mucosal ischemic changes. Most lesions (95.7 %) dramatically improved after corticosteroid therapy. This study suggests that both upper and lower gastrointestinal examinations are necessary for proper evaluation of gastrointestinal bleeding in patients with HSP.
MicroRNAs (miRNAs) can be used to target a variety of human malignancy by targeting their oncogenes or tumor suppressor genes. The developmental endothelial locus-1 (Del-1) might be under miRNA regulation. This study investigated microRNA-137 (miR-137) function and Del-1 expression in triple-negative breast cancer (TNBC) cells and tissues. Del-1 mRNA and miRNA-137 levels were determined via qRT-PCR in breast cancer cells (MDA-MB-231, MCF7, SK-BR3, and T-47D) and tissues from 30 patients with TNBC. The effects of miR-137 on cell proliferation, migration, and invasion were determined using MTT assays, wound healing, and Matrigel transwell assays. The luciferase reporter assay revealed direct binding of miR-137 to the 3′-UTR of Del-1. miR-137 inhibited cell proliferation, migration, and invasion of MDA-MB-231 cells. Among the 30 TNBC specimens, miR-137 was downregulated and Del-1 level in plasma was significantly elevated relative to normal controls. It is concluded that miR-137 regulates Del-1 expression in TNBC by directly binding to the Del-1 gene and cancer progression. The results implicate miR-137 as a new therapeutic biomarker for patients with TNBC.
The cleanliness of the colons was not significantly different among the 3 split-dose preparations. Day-prior dosing of Gatorade and 357 g of PEG allowed the mucosa to be visualized as well as did the split-dose preparations.
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.
