Treatment of cultured bovine brain microvascular endothelial cells (BMECs) with interleukin 1 beta (IL-1 beta), an inflammatory cytokine, was shown to induce the accumulation of sulfoglucuronosyl paragloboside (SGPG), a glycolipid bearing the HNK-1 epitope. This resulted in the attachment of a greater number of human lymphocytes to the treated than to the(More)
Since a number of anti-glycosphingolipid (GSL) antibody activities have been demonstrated in patients with various neurological disorders, the presence of common antigens between brain microvascular endothelial cells (BMECs) and the nervous tissues presents a potential mechanism for the penetration of macromolecules from the circulation to the nervous(More)
We analysed the glycolipid composition of glioma cells (N-370 FG cells), which are derived from a culture of transformed human fetal glial cells. The neutral and acidic glycolipid fractions were isolated by column chromatography on DEAE-Sephadex and analysed by high-performance thin-layer chromatography (HPTLC). The neutral glycolipid fraction contained 1.6(More)
We have studied the glycolipid composition of human cataractous lenses. Neutral and acidic lipid fractions were isolated by column chromatographies on DEAE-Sephadex and Iatrobeads. The neutral glycolipid fraction and acidic glycolipid fraction contained 0.6-0.9 micrograms of lipid-bound glucose (Glc) per mg of protein and 0.8-1.3 micrograms of lipid-bound(More)
AIMS In order to determine the prevalence of dementia and mild cognitive impairment (MCI), we conducted a population-based study in Japan. METHODS Participants included 924 subjects aged 65 years or older who resided in the town of Ama-cho. In phase 1 of the study, the Mini-Mental State Examination and Clinical Dementia Rating were administered for(More)
Using an in vitro blood-nerve barrier (BNB) model, the authors tested the effect of various monoclonal antiganglioside antibodies on BNB function. Only anti-GM1 antibody significantly facilitated BNB leakage in a concentration-dependent, complement-independent manner. This study provided evidence that anti-GM1 antibody, frequently detected in sera from(More)
OBJECTIVE Characteristic sleep disturbance in patients with Parkinson's disease (PD) was evaluated using a subjective questionnaire called the PD sleep scale (PDSS). In this study we sought to examine the relationship between the results from the PDSS with those from the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), and(More)
We aimed to clarify the longitudinal course of mild parkinsonian signs (MPS) and their association with dementia and functional disability by conducting a comprehensive epidemiological study, including brain MRI, and assessments of cognition, depression, and sleep, in people aged ≥65years living in Ama-cho. We diagnosed MPS and parkinsonism (PS) using a(More)
