Identical-size graphene nanoclusters (GNCs) form on Ru(0001) mediated by the substrate-induced clustering effect. The two kinds of uniform GNCs were identified as the seven C6-ring (noted as 7-C6) and three C6-ring (3-C6) structures with a dome-shape by using scanning tunneling microscopy.

The follicle-associated epithelium (FAE) of Peyer's patches (PPs) contains M cells that are important for reducing mucosal immune responses by transporting antigens into the underlying lymphoid tissue. We generated a monoclonal antibody (C6) that reacted with the FAE of calf ileal PPs, and analyzed the characteristics of C6 using immunohistochemistry and Western blotting. FAE of the ileal PP wa...

Endostatin is an anti-angiogenic agent that blocks endothelial cell proliferation, tumor growth, and metastasis. Several lines of direct evidence show that gliomas express high levels of endostatin. However, the anti-angiogenic activity and cellular mechanisms of endostatin from tumor cells have not been completely elucidated. In this study, we established C6 glioblastoma (GBM) xenografts in nu...

Complement is implicated in pathology in the human demyelinating disease multiple sclerosis and in animal models that mimic the demyelination seen in multiple sclerosis. However, the components of the complement system responsible for demyelination in vivo remain unidentified. In this study, we show that C6-deficient (C6-) PVG/c rats, unable to form the membrane attack complex (MAC), exhibit no...

The detection of antibody to the Borrelia burgdorferi C6 peptide by use of enzyme-linked immunoassays is a widely accepted method for the diagnosis of Lyme disease spirochete infection in dogs and in humans. Antibody to the C6 peptide is highly specific for B. burgdorferi and declines following treatment of dogs and humans exposed to B. burgdorferi. A quantitative assay for determining C6 antib...

We examined the metabolism and intracellular transport of the D-erythro and L-threo stereoisomers of a fluorescent analogue of sphingomyelin, N-(N-[6-[(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino] caproyl])-sphingosylphosphorylcholine (C6-NBD-SM), in Chinese hamster ovary (CHO-K1) fibroblast monolayers. C6-NBD-SM was integrated into the plasma membrane bilayer by transfer of C6-NBD-SM monomers from...

Melanoma is one common skin cancer. In the present study, the potential anti-melanoma activity by a liposomal C6 ceramide was tested in vitro. We showed that the liposomal C6 (ceramide) was cytotoxic and anti-proliferative against a panel of human melanoma cell lines (SK-Mel2, WM-266.4 and A-375 and WM-115). In addition, liposomal C6 induced caspase-dependent apoptotic death in the melanoma cel...

Study Design Retrospective case series. Objectives The kinematics of the cervical spine has been investigated by many researchers. However, the occupancy of the disk bulges, spinal cord, ligamentum flavum, and the rest of the canal as well as the changes of these structures with motion have not yet been investigated. The goal of this study is to investigate these dynamic changes. Methods The ki...
