Lexis in Chinese-English Translation of Drug Package Inserts: Corpus-based Error Analysis and Its Translation Strategies
Lin Ying,Zhou Yumei
International Journal of Biomedical Science , 2011,
Abstract: Error analysis (EA) has been broadly applied to the researches of writing, speaking, second language acquisition (SLA) and translation. This study was carried out based on Carl James’ error taxonomy to investigate the distribution of lexical errors in Chinese-English (C-E) translation of drug package inserts (DPIs), explore the underlying causes and propose some translation strategies for correction and reduction of lexical errors in DPIs. A translation corpus consisting of 25 DPIs translated from Chinese into English was established. Lexical errors in the corpus and the error causes were analyzed qualitatively and quantitatively. Some examples were used to analyze the lexical errors and their causes, and some strategies for translating vocabulary in DPIs were proposed according to Eugene Nida’s translation theory. This study will not only help translators and medical workers reduce errors in C-E translation of vocabulary in DPIs and other types of medical texts but also shed light on the learning and teaching of C-E translation of medical texts.

Virology Journal , 2011, DOI: 10.1186/1743-422x-8-245
Abstract: To further test for processing and to rule out artifacts associated with the expression system, ORF1 was re-expressed using a plasmid-based expression vector with the result that the previous processing profile could not be confirmed. When ORF1 from an HEV infectious cDNA clone (US swine strain; genotype 3) was expressed using the plasmid-based system, the only species detected was the 185 kDa precursor of ORF1. A putative papain-like cysteine protease [2] had been predicted within ORF1 using the original HEV genomic sequence. However, analysis of subsequent ORF1 sequences from a large number of HEV isolates reveals that this protease motif is not conserved.The expressed HEV ORF1 gene product does not undergo proteolytic processing, indicating that the replicase precursor of HEV is potentially unique in this regard.Hepatitis E virus (HEV) is the sole member of the genus Hepevirus belonging to the family Hepeviridae [reviewed in [3]]. HEV is a non-enveloped, plus-sense, single-stranded RNA virus whose genome is approximately 7.2 kb in length and consists of three open reading frames (ORFs): the 5' proximal ORF1 of ~5100 nt which encodes the viral replicase components; the 3' proximal ORF2 of ~2000 nt which encodes the capsid protein; and ORF3 of ~400 nt, which encodes a phosphoprotein of unknown function. ORF2 and ORF3 overlap and are translated from a single subgenomic RNA species. Computer-assisted sequence alignment of the deduced translation product of ORF1 with replicase proteins of other animal and plant plus-strand RNA viruses led to the identification of several common motifs, including putative methyl/guanylyl-transferase, papain-like cysteine protease (PCP), poly ADP ribose phosphatase, helicase and RNA-dependent-RNA-polymerase (RDRP) domains [2](see Figure 1). Of these, activity of the methyl/guanylyl transferase, the helicase, and the RDRP domains have been experimentally demonstrated [4-7].Proteolytic processing of replicase polyprotein precursors into m
A Corpus-Based Study of Cohesion in English Medical Texts and its Chinese Translation
Jia Zhao,Wenli Yan,Yumei Zhou
International Journal of Biomedical Science , 2009,
Abstract: Cohesion as an indispensable linguistic feature in discourse analysis and translation has aroused many researchers’ interest. To explore the regularity in shifting cohesive devices from English into Chinese our study was designed to analyze the similarities and differences of cohesive devices between English medical texts (EMTs) and their Chinese translation texts (CTTs). A parallel corpus consisting of 15 EMTs and 15 CTTs was established, each type of cohesive devices was identified, and paired t-test was run for statistic analysis. We have revealed that both EMTs and CTTS share more similarities than differences in the use of cohesive devices; the differences between them only exist in the employment of reference in terms of occurrence frequencies; the majority of cohesive devices are maintained in Chinese translation for precision, clarity and logicality. Our study will not only help medical students and medical workers but also shed light on EMP teaching and research.

Abstract: Novel visible-light-active Mn–C–TiO2 nanoparticles were synthesized by modified sol-gel method based on the self-assembly technique using polyoxyethylenes orbitan monooleate (Tween 80) as template and carbon precursor and manganese acetate as manganese precursor. The samples were characterized by XRD, FTIR, UV-vis diffuse reflectance, XPS, and laser particle size analysis. The XRD results showed that Mn–C–TiO2 sample exhibited anatase phase and no other crystal phase was identified. High specific surface area, small crystallite size, and small particle size distribution could be obtained by manganese and carbon codoped and Mn–C–TiO2 exhibited greater red shift in absorption edge of samples in visible region than that of C–TiO2 and pure TiO2. The photocatalytic activity of synthesized catalyst was evaluated by photocatalytic oxidation of methyl orange (MO) solution under the sunlight irradiation. The results showed that Mn–C–TiO2 nanoparticles have higher activity than other samples under sunlight, which could be attributed to the high specific surface area, smaller particle size, and lower band gap energy. 1. Introduction Photocatalytic degradation of toxic organic compounds has received a great attention for the past several years. Due to its strong oxidizing powder, being cost effective, and long-term stability against photo- and chemical corrosion, TiO2 has been widely used in water purification technology [1–4]. However, the practical applications of TiO2 are limited by its large band gap (3.2?eV), which can be only active under the UV light irradiation [5–7]. Therefore, several strategies have been developed to shift the optical sensitivity of TiO2 from UV to the visible-light region for the efficient use of solar energy, such as element doping, metal deposition, surface sensitization, and couping of composite semiconductors [8]. Recently, C, N, F, S anion-doped TiO2 photocatalysts that show a relatively high level of activity under visible-light irradiation have been reported [9]. These nonmetal elements have been proved to be beneficial dopants in the TiO2 via mixing their p orbital of nonmetal with O 2p orbital to reduce the band gap energy of TiO2. The doping of various transitional metal ions into TiO2 could shift its optical absorption edge from UV into visible-light range, but a prominent change in TiO2 band gap has not been observed [10]. This red shift in metal doped TiO2 was attributed to the charge-transfer transition between the d electrons of the dopant and the conduction band (CB) of TiO2 [11]. However, transition metal-doped TiO2

Abstract: The inhibitory effect of three berberine alkaloids (BAs) from Coptis chinensis Franch, a traditional Chinese medicinal (TCM) herb, on Bifidobacterium adolescentis growth was investigated by microcalorimetry. The power-time curves of B. adolescentis with and without BAs were acquired, meanwhile the extent and duration of inhibitory effect on the metabolism were evaluated by the growth rate constant (k), half inhibitory ratio (IC50), maximum heat-output power (P max), peak time of maximum heat-output power (t p) and total heat production (Q t). k, P max and Q t decreased, and t p was prolonged with the increase of BAs concentration. The IC50 of BAs is 806 μg/mL for berberine, 341 μg/mL for coptisine and 236 μg/mL for palmatine. The sequence of antimicrobial activity of BAs is berberine < coptisine < palmatine. Combined with previous studies, it could be shown that the sequences of antimicrobial activity of BAs on both Bacillus shigae and Escherichia coli are berberine > coptisine > palmatine. The structure-function relationship of BAs indicates that the functional group methylenedioxy or methoxyl at C2 and C3 might be the major group inducing the activities of BAs on E. coli and B. adolescentis. Meanwhile, the substituent groups at C2, C3, C9 and C10 almost have equal effect on B. shigae.

Chinese Science Bulletin , 2002, DOI: 10.1360/02tb9246
Abstract: Senescence-related protease may play an important role in leaf senescence. By improved SDS-Gelatin-PAGE assay, a 63 ku senescence-related protease (63 SRP) in coriander leaves was identified. Activity of 63 SRP was increased in parallel to the advance of coriander leaf senescence, and inhibited by treating the leaf with gibberellic acid, and enhanced by ethylene treatment. The 63 SRP was suggested to be a serine protease based on the fact that its activity was inhibited by the protease inhibitor PMSF. The optimal temperature for the activity of the 70 ku protease was 50°C. The maximal activity was observed at pH 6–9, some activity could be observed on the gel slices incubated at pH 5 or 11. The 63 SRP was partly purified by the way of ammonium sulfate precipitation and then gel slicing after gel electrophoresis.

International Journal of Biomedical Science , 2006,
Abstract: Using an animal model of colonic inflammation, the effects of intrathecal (i.t.) diazepam (0.02mg/kg, 0.08mg/kg and 0.15mg/kg) on visceral pain-related behaviors and hyperalgesia associated with colonic inflammation were investigated. In this visceral pain model, acute visceral pain response was induced by intracolonic (i.c.) injection of 0.5 ml of dilute formalin (2%, 5% and 10%) in rats, and the peak pain behavioral response and hyperalgesia were evoked by i.c. 5% formalin. I.t. diazepam (0.02mg/kg, 0.08mg/kg and 0.15mg/kg) followed 10 min later by i.c. injection of 5% formalin, attenuated the visceral pain behaviors induced by 5% formalin in a dose dependent manner. Of the three doses tested, the duration of the suppressive effect of 0.15mg/kg diazepam on visceral pain was the longest, which is 60 min compared with 45 min at other two doses. Moreover, i.t. pretreatment with 0.08mg/kg diazepam attenuated the hyperalgesia induced by i.c. injection of 5% formalin. The findings in our studies shown that i.t. diazepam had a suppressive effect on visceral pain associated with noxious stimulation of colon, and provided evidence that diazepam may be used as an analgesic drug in the future.
