Multivariate statistical methods, such as cluster analysis (CA), discriminant analysis (DA) and principal component analysis (PCA), were used to analyze the water quality dataset including 13 parameters at 18 sites of the Daliao River Basin from 2003-2005 (8424 observations) to obtain temporal and spatial variations and to identify potential pollution(More)
The novel neuroprotective action of Humanin (HN), especially its derivative [Gly(14)]-humanin (HNG), against Alzheimer's disease (AD)-related insults has been reported. However, it is still short of electrophysiological evidence for the protection of HN on synaptic plasticity, and the molecular mechanisms that underlie the neuroprotective function of HN(More)
System identification is very important to technical and nontechnical areas. All physical systems are nonlinear to some extent and it is natural better to use nonlinear model to describe a real system. The Wiener and Hammerstein systems are proved to be good descriptions of nonlinear dynamic systems in which the nonlinear static subsystems and linear(More)
Algal polyunsaturated fatty acids (PUFA), essential for somatic growth and reproduction of aquatic animals, are influenced by ambient environmental conditions, including light and nutrients. Few studies have addressed the extent to which changes in algal PUFA can influence stream herbivore PUFA profiles and the implications for stream food webs. We(More)
Mangroves have been increasingly recognized for treating wastewater from aquaculture, sewage and other sources with the overwhelming urbanization trend. This study clarified the three paradigms of mangroves in disposing wastewater contaminants: natural mangroves, constructed wetlands (including free water surface and subsurface flow) and(More)
Amyloid beta protein (Abeta) is thought to be responsible for the loss of memory in Alzheimer's disease (AD). A significant decrease in [Arg(8)]-vasopressin (AVP) in the AD brain has been found. However, it is unclear whether the decrease in AVP is involved in Abeta-induced impairment of memory and whether AVP can protect against Abeta-induced(More)
The amyloid β-protein (Aβ)-induced disturbance of intracellular calcium homeostasis has been regarded as the final route whereby Aβ insults neurons. However, the mechanism of Aβ-induced Ca(2+) overloading is still unclear so far. Especially, it remains to be clarified whether nicotinic acetylcholine receptors (nAChRs) are involved in the Aβ-induced(More)
AIM To study the feasibility of long-term potentiation(LTP) recording in the CA1 area of the rat in vivo with electrodes-binding technique. METHODS Anesthetizing Wistar rats with urethane and fixing the animal on the stereotaxic device for acute surgery; implanting cannula into lateral cerebral ventricle; inserting self-made bound stimulating/recording(More)
In the central nervous system (CNS), vesicular monoamine transporter 2 (VMAT2) transports cytoplasmic monoamines such as dopamine into synaptic vesicles for storage and subsequent exocytotic release. Recent studies have provided direct evidence for VMAT2-regulated monoamine neurotransmitter involvement in the neurophysiological activities of neurological(More)
