PURPOSE We evaluated the prevalence and features of cerebral aneurysms in the family members of people with asymptomatic aneurysms among 8680 participants undergoing magnetic resonance angiography. METHODS Of the 8680 participants, 380 had family histories of aneurysms and 8300 did not. The prevalence and features of asymptomatic aneurysms were compared… (More)
The rapid spontaneous resolution of two traumatic acute hematomas, one extradural and one subdural, is reported in a 17-year-old young man. The authors believe that this is the first report of simultaneous resolution of both types of hematoma.
The complement system membrane cofactor protein (MCP) CD46 serves as a C3b/C4b inactivating factor for the protection of host cells from autologous complement attack and as a receptor for measles virus (MV). MCP consists of four short consensus repeats (SCR) which are the predominant extracellular structural motif. In the present study, we determined which… (More)
A simple method for the determination of C3b inactivator in human plasma was investigated. Fluorescent-labeled C3, which was prepared by treatment with methylamine and a fluorescent thiol reagent, N-(dimethylamino-4-methylcoumarinyl)-maleimide, was used as the substrate. Diluted human plasma is incubated with fluorescent C3, reduced with 2-mercaptoethanol,… (More)
We present a case of a 15-month-old infant with intracranial cavernous angioma in the right frontal lobe in which the cerebral angiogram revealed transmedullary collecting veins characteristic of venous angioma around the lesion. This vascular malformation was histologically confirmed to be a cavernous angioma.
To identify the genes, and the mechanisms that account for the 53% higher peak bone density in C3H/HeJ (C3H) mice compared with C57BL/6J (B6) mice, we are performing quantitative trait locus and phenotypic analyses. The phenotypic studies revealed differences in bone formation and resorption, and showed that hindlimb immobilization (by sciatic neurectomy)… (More)
The catalytic site for C4 of C1s has been presumed to consist of a C4-binding domain and a proteolytic domain. A mAb to C1s, M81, blocked C4 activation and C4 binding to C1s. M81 recognized the H chain of C1s. Using M81 as a probe, we tried to define C4-binding site on C1s. Plasmin digestion of C1s generated four products of Mr 58,000 (P1), 48,000 (P2),… (More)
In this report we demonstrate that alpha 2-macroglobulin (alpha 2M) is a carrier protein for IL-6. IL-6 was found to bind plasma proteins and an immunoblot analysis revealed that the complex between IL-6 and plasma proteins contains alpha 2M. Furthermore, purified alpha 2M bound IL-6. alpha 2M did not inhibit IL-6 activity or its binding to homologous… (More)
Hamster complement C1s cDNA was inserted into expression plasmid BCMGSNeo, and transfected to SEA7 cells, A31 mouse fibroblasts transformed by polyoma virus. The transfectant secreted a large amount of recombinant C1s that was activated in the serum free culture medium and hydrolyzed acetyl-Gly-L-Lys-naphthyl ester (AGLNE). C1s was purified to a homogeneity… (More)
