... challenging task for learners of Chinese. To read everyday news articles, one needs to learn thou- sands of Chinese characters. The official agents in Taiwan and China, respectively, chose 5401 ... Techniques for decomposing Chinese characters and for comparing the similarity between Chinese characters were employed to recommend lists of Chinese characters for authoring the...

... we determined that only a few cysteine residues among the total of 72 are exposed to the environment: 10 sol- vent-accessible cysteines were determined to be present on the surface, with some ... protein signals were detected using enhanced chemilu- minescence western blotting detection reagents (Amersham Biosciences). Proteasome samples analyzed using anti-GSH serum were mixed with gel ......

... we determined which conserved sequences were also present in distant vertebrates, including opossum, chicken, zebrafish and fugu. The multiple alignments revealed the presence of a conserved sequence ... genes; a genomic region conserving the synteny between humans and mice (see Ensembl, which provides gen- ome sequences for vertebrates). Moreover, the sequences of pre-miR-375 in b...

... prevalence of B. henselae in Korean pet cats was higher than reported prevalence in other countries. This is the first report examining the prevalence of B. henselae and B. clarridgeiae infection in ... We examined the prevalence of B. henselae and B. clarridgeiae in dogs and cats in the present study using a recently developed nested PCR method. Blood, saliva, an...

... in erythrocyte SOD levels indicates a decrease in the tissues’ ability to handle excessive free radicals [2]. However, an increase in catalase activity enhances the scavenging ability of erythrocytes ... the changes suggest that the accumulation of excess free radicals may be responsible for the increased lipid peroxidation which sensitizes the cells to various degenerative dis...

The mean values of K per ring were then used to determine leaf ... omission of one or two rings. The consequences of neglecting these rings are discussed, together with the respective interest of both techniques. (© Inra/Elsev...

... These results also suggest that the overexpression of either cyclin D1 or cyclin E is not a mere consequence of cellular proliferative activity, but rather represents a true difference between ... staining revealed exclusive nuclear staining of the neoplastic cells for cyclin D1, cyclin E and PCNA. Cyclin D1 expression was detected in 56.3% of the adenomas and...
