PURPOSE China's freshwater subtropical shallow lakes are increasingly eutrophic and susceptible to production of heavy growths or water blooms of cyanobacteria. One example was the heavy water bloom that occurred for the first time in Lake Xuanwu, in 2005, an urban lake located in Nanjing city. The aim of the present study was to determine dynamics of water(More)
BACKGROUND Dementia is increasingly prevalent due to rapid aging of the population, but under-recognized among people with low education levels. This is partly due to a lack of appropriate and precise normative data, which underestimates cognitive aging in the use of screening tools for dementia. OBJECTIVE We aimed to improve the precision of screening(More)
It has been shown that inhaled cigarette smoke activates vagal pulmonary C fibers and rapidly adapting receptors (RARs) in the airways and that nicotine contained in the smoke is primarily responsible. This study was carried out to determine whether nicotine alone can activate pulmonary sensory neurons isolated from rat vagal ganglia; the response of these(More)
A neutral polysaccharide fraction (ARP) prepared from the rhizome of Anemone raddeana was tested for its anticancer activity in H22 tumor-bearing mice by oral administration. ARP could not only significantly inhibit the growth of H22 transplantable tumor, but also remarkably promote splenocytes proliferation, NK cell and CTL activity, as well as serum IL-2(More)
Self-propagation is characteristic property for a prion conformation. Previous studies revealed that prion protein expressed in the cytoplasm gained a PrP(Sc)-like conformation. However, it remains unclear whether the PrP(Sc)-like conformation has the self-propagating property. We found that PrP partially purified from yeast cytoplasm formed amyloid fiber(More)
AIM H2 S, a newly discovered signaling gasotransmitter, has been found involved in the pathogenesis of portal hypertension through the H2 S/CSE system. Studies also showed that urotensin II (UII), a recently discovered most potent vasoconstrictor, played an important role in cirrhotic portal hypertension. Therefore, studies were conducted to explore the(More)
To convert the hydrophilic surface of bamboo flour into a hydrophobic surface, methyl methacrylate (MMA) was grafted onto bamboo flour surface by means of atom transfer radical polymerization (ATRP) method. The grafted bamboo flour was characterized by using Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy, scanning electron(More)
Reaction of β-amino-β-(pyrid-4-yl)acrylonitrile with the aromatic dicarboxaldehydes 9,10-bis(4-formylphenyl)anthracene and terephthalaldehyde affords the dihydropyridyl products 9,10-bis(4-((3,5-dicyano-2,6-dipyridyl)dihydropyridyl)phenyl)anthracene (L(1)) and 1,4-bis(4-(3,5-dicyano-2,6-dipyridyl)dihydropyridyl)benzene (L(2)), respectively. In the solid(More)
The aim of this study was to improve the electrical resistivity, mechanical properties, and interfacial properties between the carbon fiber (CF) and cellulose of conductive paper containing 10% CF so as to better meet the demands for electric heating wood floors. With waterborne polyurethane (WPU) treatment and nitrogen plasma modification methods, the(More)
