Alzheimer's disease (AD) is attributable to synapse dysfunction and loss, but the nature and progression of the presynaptic structural and functional changes in AD are essentially unknown. We expressed wild-type or arctic form of beta amyloid(1-42) (Abeta) in a small group of neurons in the adult fly and performed extensive time course analysis of the(More)
The accumulation of beta amyloid (Aβ) can cause synaptic impairments, but the characteristics and mechanisms of the synaptic impairment induced by the accumulation of Aβ in Alzheimer's disease (AD) remain unclear. In identified single neurons in a newly developed Drosophila AD model, in which Aβ accumulates intraneuronally, we found an age-dependent(More)
Beta amyloid (Aβ42)-induced dysfunction and loss of synapses are believed to be major underlying mechanisms for the progressive loss of learning and memory abilities in Alzheimer’s disease (AD). The vast majority of investigations on AD-related synaptic impairment focus on synaptic plasticity, especially the decline of long-term potentiation of synaptic(More)
Low molecular weight and sulfated low molecular weight guluronate (LMG and SLMG) were prepared and hypolipidemic effects were studied in a human hepatocellular carcinoma HepG2 cell line. Both compounds decreased total cholesterol (TC) and triglycerides (TG) and inhibited 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) activity in HepG2 cells. In general,(More)
The fine structure of enoxaparin sodium samples with different degree of 1,6-anhydro derivatives were analyzed with polyacrylamide gel electrophoresis, high performance liquid chromatography, ultraviolet spectroscopy, infrared spectroscopy and nuclear magnetic resonance spectroscopy. A further study of anticoagulation activity of enoxaparins was performed,(More)
Many biotic and abiotic stresses can cause oxidative stress in plants. The identification of components involved in plant response to oxidative stress has attracted wide attention. The members of AtSRO family, including AtRCD1, AtSRO1, and AtSRO5, regulate plants' response to oxidative stress. AtSROs participate in plant normal growth and development, and(More)
