Vibrio cholera toxin and the heat-labile enterotoxin of Escherichia coli have been shown to differ somewhat in their ligand specificity and in the antigenicity of their binding sites. Therefore, the components of the oligosaccharide portion of GMl bound by cholera toxin and the heat-labile enterotoxin of E. coli were identified by determining the concentration of GMl, derivatives of GMl, oligos...

The ability to induce T-cell apoptosis is one mechanism by which tumors evade the immune system, although the molecules involved remain controversial. We found that renal cell carcinoma (RCC)-induced T-cell apoptosis was inhibited by >50% when cocultures were performed with ganglioside-depleted tumor cells, caspase-8-negative lymphocytes, or anti-tumor necrosis factor-alpha (TNFalpha) antibodie...

Abstract Storage of wastes leads to severe problems water pollution and neighboring matrices due the infiltration landfill leachate. Uncontrolled waste storage can lead groundwater pollution, which serious health for living. Engineered barriers be a solution these problems. The purpose this study was develop novel composite materials – clay-based, activated carbon, cement, PVA polymer. These co...

BACKGROUND GM1 gangliosidosis is a disorder due to GLB1 gene mutation. CASE CHARACTERISTICS A 4-yr-old boy with neuroregression and optic atrophy with periventricular hyperintensity on magnetic resonance imaging. OUTCOME Beta galactosidase enzyme activity was low which was confirmed by GLB1 sequencing. MESSAGE We highlight the white matter changes in late infantile GM1 gangliosidosis.

Anti-ganglioside (anti-GM1) antibodies have been implicated in the pathogenesis of Guillain-Barré syndrome, multifocal motor neuropathy and motor neuron diseases. It has been held that they may interfere with saltatory conduction by blocking sodium channels. We tested this hypothesis by analysing action potentials from 140 single nerve fibres in 22 rat ventral roots using external longitudinal ...

UNLABELLED Ganglioside GM1, which is particularly abundant in the central nervous system (CNS), is closely associated with the protection against several CNS disorders. However, controversial findings have been reported on the role of GM1 following ischemic stroke. In the present study, using a rat middle cerebral artery occlusion (MCAO) model, we investigated whether GM1 can protect against is...

OBJECTIVES To investigate the incidence of hyperreflexia in patients with Guillain-Barré syndrome (GBS), and its relation with electrodiagnosis of acute motor axonal neuropathy (AMAN), antiganglioside GM1 antibody, and Campylobacter jejuni infection. It was reported that patients with AMAN in northern China often had hyperreflexia in the recovery phase. METHODS In 54 consecutive Japanese pati...

In the present study, human umbilical cord-derived mesenchymal stem cells (hUMSCs) were investigated for their potential to be induced to differentiate in vitro into neuron-like cells by monosialoteterahexosyl ganglioside (GM1). Mononuclear cells obtained from umbilical cords from women with full-term pregnancies whose babies were delivered by cesarean section were cultivated in vitro and their...

Ganglioside GM1 (100 mg) was given daily by intramuscular injection for 28 days in a double-blind placebo controlled trial of acute stroke. No significant difference was detected in a 6 month follow-up period between well matched control and active groups. Although the number of patients studied was small the findings are believed to indicate that GM1 is unlikely to be of value in the treatment...
