We report an apparently novel toxic effect of the dinoflagellate Alexandrium tamarense, manifested by inhibition of the egg hatching success of the scallop, Chlamys farreri. The hatching rate of C. farreri approached only 30% of controls when its fertilised eggs were exposed for 36h to A. tamarense cells or cellular fragments at a concentration of 100(More)
A review was made on the main environmental characteristics such as currents and water body, diluted water and its turning direction, upwelling, front, nutrients and its sources and plankton community in the Changjiang River estuary and its adjacent sea areas which could affect the growth, migration, assembling, resting and competition of harmful algae to(More)
In this study the role of the TOP2 gene in fungal drug susceptibility was investigated by disrupting and overexpressing the gene in Candida albicans. MIC determination and a spot assay showed that a top2Delta/Delta null mutant (strain T2bc) was more resistant to the antifungals tested than the wild-type (strain CAI4). Real-time RT-PCR and rhodamine 6G(More)
AIM To examine the effects of pioglitazone, a PPARγ agonist, on memory performance and brain amyloidogenesis in streptozotocin (STZ)-induced diabetic mice. METHODS ICR male mice were injected with STZ (150 mg/kg, iv) to induce experimental diabetes. Pioglitazone (9 and 18 mg·kg(-1)·d(-1), po) was administered for 6 weeks. Passive avoidance and Morris(More)
Amyloid-β peptide (Aβ) is thought to be associated with the progressive neuronal death observed in Alzheimer's disease (AD). However, effective neuroprotective approaches against Aβ neurotoxicity are unavailable. Here, we investigated possible preventive effects of ibudilast, as a pharmacologic phosphodiesterase inhibitor, currently used for treatment of(More)
BACKGROUND Sunscreens are an important component of healthy sun-protection behavior. To achieve satisfactory protection, sunscreens must be applied consistently, evenly and correctly. Consumers do not apply sunscreen properly and, therefore, do not achieve the protection indicated by the label 'sun protection factor' (SPF). The objective of the present(More)
A series of novel derivatives of phenyl-substituted berberine triazolyls has been designed and synthesized via copper-catalyzed azide-alkyne cycloaddition click chemistry in an attempt to develop antitumor agents. All of the compounds were evaluated for anticancer activity against a panel of three human cancer cell lines, including MCF-7 (breast), SW-1990(More)
The small mysid crustacean Neomysis awatschensis was collected in the west coast of Jiaozhou Bay, Qingdao, China in 1992 and acclimated and cultured in laboratory conditions since then. Standard acute toxicity tests using 4-6 d juvenile mysids of this species were conducted and the results were compared with Mysidopsis bahia, a standard toxicity test(More)
Image interpolation has been widely used and studied in the fields of image processing. Considering the different complexities along the different directions, a novel image interpolation method based on gradient analysis is presented in this article. First, for each point that need to be interpolated, the gradient values along the horizontal and vertical(More)
