The human gut microbiota is a complex system that is essential to the health of the host. Increasing evidence suggests that the gut microbiota may play an important role in the pathogenesis of colorectal cancer (CRC). In this study, we used pyrosequencing of the 16S rRNA gene V3 region to characterize the fecal microbiota of 19 patients with CRC and 20(More)
The beneficial effects of Bifidobacteria on health have been widely accepted. Patients with chronic liver disease have varying degrees of intestinal microflora imbalance with a decrease of total Bifidobacterial counts. Since different properties have been attributed to different Bifidobacterium species and there is no information available for the detailed(More)
Human gut microbiota plays an important role in the pathogenesis of cirrhosis complications. Although the phylogenetic diversity of intestinal microbiota in patients with liver cirrhosis has been examined in several studies, little is known about their functional composition and structure. To characterize the functional gene diversity of the gut microbiome(More)
Tumor necrosis factor receptor-associated factor 6 (TRAF6), a unique E3 ubiquitin ligase and adaptor protein, is involved in activation of various signaling cascades. Recent studies identify TRAF6 as one of the novel regulators of skeletal muscle atrophy. The role of TRAF6 in glucocorticoid-induced muscle atrophy, however, remains to be elucidated. In this(More)
This study aimed to summarize therapy experience of carotid endarterectomy, carotid endarterectomy combined with Fogarty catheter embolectomy, and hybrid surgery for the treatment of extracranial internal carotid artery occlusion. The study included 65 patients with extracranial internal carotid artery occlusion who underwent carotid endarterectomy, carotid(More)
A cerebral aneurysm occurs as a result of a weakened blood vessel, which allows blood to flow into a sac or a ballooned section. Recent advancement shows that a new device, 'flow-diverter', can divert blood flow away from the aneurysm sac. People found that a flow-diverter based on thin film nitinol (TFN), works very effectively, however there are no(More)
