Introduction: Prostate cancer (PCa) is the third most prevalent cancer among Malaysian males, often diagnosed at advanced stages, leading to suboptimal outcomes. While transrectal ultrasound-guided systematic biopsy (TRUS-SB) is the primary diagnostic method, prebiopsy multiparametric magnetic resonance imaging (mpMRI) is gaining popularity in identifying suspicious lesions. This study addresses the lack of comprehensive investigations into the efficacy of cognitive registration TRUS targeted biopsy (COG-TB) compared to conventional TRUS-SB, considering the resource limitations of the Malaysian healthcare system. Materials and Methods: A retrospective cohort study was conducted in two Malaysian healthcare facilities. 116 adult patients with a prostate-specific antigen (PSA) level of more than 4 ng/mL who underwent both COG-TB and TRUS-SB between October 2020 and March 2022 were included. Primary outcomes were cancer detection rate and histopathological outcomes, including Gleason score. Results: COG-TB showed a higher overall cancer detection rate (50%) compared to TRUS-SB (44%). Clinically significant cancer detection rates were similar between COG-TB and TRUS-SB (37.1%). Further analysis revealed that both COG-TB and TRUS-SB detected clinically significant cancer in 30.2% of patients, did not detect it in 56.0%, and had conflicting findings in 16 patients (p Conclusion: COG-TB and TRUS-SB have comparable detection rates for clinically significant prostate cancer, with COG-TB showing a higher tendency to detect insignificant prostate cancer. Further studies comparing these methods are warranted.

A truncated hepatitis E virus ORF2 protein expressed in tobacco plastids is immunogenic in mice

引用

World Journal of Gastroenterology 2006年第2期12卷 306-312页

作者： Yuan-Xiang Zhou Maggie Yuk-Ting Lee James Ming-Him Ng Mee-Len Chye Wing-Kin Yip sze-yong Zee Eric Lam Department of Botany The University of Hong Kong PokfulamRoad Hong Kong China Biotech Center Rutgers University 59 Dudley RoadNew Brunswick NJ 08901-8520 United States

AIM： To cost-effectively express the 23-ku pE2, the most promising subunit vaccine encoded by the E2 fragment comprising of the 3＇-portion of hepatitis E virus （HEV） open reading frame 2 （ORF2） in plastids of tobacco （Nicotiana tabacum cv. SR1）, to investigate the transgene expression and pE2 accumulation in plastids, and to evaluate the antigenic effect of the plastid-derived pE2 in mice. METHODS： Plastid-targeting vector pRB94-E2 containing the E2 fragment driven by rice psbA promoter was constructed. Upon delivery into tobacco plastids, this construct could initiate homologous recombination in psaB-trnfM and trnG-psbC fragments in plastid genome, and result in transgene inserted between the two fragments. The pRB94-E2 was delivered with a biolistic particle bombardment method, and the plastid-transformed plants were obtained following the regeneration of the bombarded leaf tissues on a spectinomycin-supplemented medium. Transplastomic status of the regenerated plants was confirmed by PCR and Southern blot analysis, transgene expression was investigated by Northern blot analysis, and accumulation of pE2 was measured by ELISA. Furthermore, protein extracts were used to immunize mice, and the presence of the pE2-reactive antibodies in serum samples of the immunized mice was studied by ELISA. RESULTS： Transplastomic lines confirmed by PCR and Southern blot analysis could actively transcribe the E2 mRNA. The pE2 polypeptide was accumulated to a level as high as 13.27 μg/g fresh leaves. The pE2 could stimulate the immunized mice to generate pE2-specific antibodies. CONCLUSION： HEV-E2 fragment can be inserted into the plastid genome and the recombinant pE2 antigen derived is antigenic in mice. Hence, plastids may be a novel source for cost-effective production of HEV vaccines.

Detection of Stage I nasopharyngeal carcinoma by serologicscreening and clinical examination

Chinese Journal of Cancer 2011年第2期30卷 120-123页

作者： Ming-Fang Ji Yuan-Long Yu Wei-Ming Cheng yong-Sheng Zong Park sze-Park Ng Daniel Tsin-Tien Chua Mun-Hon Ng Cancer Research Institute of Zhongshan City Zhongshan Guangdong 528403 P R China Department of Pathology Sun Yat-sen Medical College Sun Yat-sen University Guangzhou Guangdong 510080 P.

China Department of Clinical Oncology Faculty of Medicine The University of Hong Kong Hong Kong SAR P. R. China

In a prospective study, 42 048 adults residing in Zhongshan City, Guangdong, China, were followed for 16 years, and 171 of them developed nasopharyngeal carcinoma (NPC). Although Epstein-Barr virus (EBV) antibody levels of the cohort fluctuated, the antibody levels of 93% of the patients with NPC were raised and maintained at high levels for up to 10 years prior to diagnosis. This suggests that the serologic window affords an opportunity to monitor tumor progression during the preclinical stage of NPC development, facilitating early NPC detection. We reviewed the clinical records of the 171 patients with NPC in the prospective study to assess the efficacy of early NPC detection by serologic screening and clinical examination. Of the 171 patients, 51 had Stage I tumor (44 were among the 73 patients detected by clinical examination and 7 were among the 98 patients presented to outpatient department). Initial serologic screening predicted 58 (95.1%) of the 61 patients detected within 2 years. The risk of the screened population (58/3093) raised 13 times relative to cohort (61/42 048) during this period. Clinical examination detected all the 58 predicted cases, and 35 (60.3%) of which were diagnosed with Stage I tumor. The serologic prediction rate fell to 33.6% (37/110) 2 to 16 years after screening. The proportion of cases detected by clinical examination fell to 40.5% (15/37). The proportion of Stage I tumors among the cases detected by clinical examination during both periods remained at about 60%. We concluded that early detection of NPC can be accomplished by repeated serologic screening to maintain high prediction rates and by promptly examining screened subjects to detect tumors before the symptoms develop.

Expression of Six Chloroplast Genes in <i>Jatropha curcas</i>Callus under Light and Dark Conditions

引用

American Journal of Plant Sciences 2011年第5期2卷 650-656页

作者： Wilson Thau Lym yong Cassandra sze Yii Chew Kenneth Francis Rodrigues 不详

The induction of genes encoded in the open reading frames (ORFs) of chloroplast genomes have been posited to be influenced by ambient light condition. The current study focused on determining which of the six ORFs, encoding the genes ycf 1, ycf 2, psbD (photosystem II), rbcl (Rubisco), matK (Maturase K) and rpoC1 (RNA polymerase) were influenced by light. Characterization of gene expression at the whole plant level and callus stage facilitates the identification of transcripts which are differentially regulated under these environmental conditions. Specificity of these primers was tested against genomic DNA and total RNA. Transcripts of six targeted genes were detected in all three replicates of the green and white callus under light and dark conditions, except for ycf 2 gene in green callus under light. The result showed that a partial transcript of the gene ycf 2 located on the J. curcas chloroplast genome was not detectable using reverse transcription PCR. This finding was then validated using quantitative real-time PCR. The gene was suspected to be post-transcriptionally modified. The transcripts of the remaining five ORFs could be detected using quantitative real-time PCR. Specific transcripts can be identified for application as biomarkers for selection of callus for plantlet regeneration.
