    Abstract Colorectal cancer (CRC) is one of the most common cancers worldwide. Postoperative adjuvant chemotherapy is recommended for node-positive stage III patients. A systematic meta-analysis reported that the presence of micrometastases in regional lymph nodes (LNs) was associated with poor survival in patients with node-negative CRC. Because most data employed in the meta-analysis were based on retrospective studies, we conducted a prospective clinical trial and concluded that stage II is a transitional zone between stage I and stage III, where CRC tumors continuously increase the micrometastasis volume in LNs and proportionally raise the risk for tumor recurrence. The one-step nucleic acid amplification (OSNA) assay is a simple and rapid technique to detect CK19 mRNA using the reverse-transcription loop-mediated isothermal amplification (RT-LAMP) method. Using the OSNA assay, we and colleagues reported that the upstaging rates of pStages I, IIA, IIB, and IIC were 2.0%, 17.7%, 12.5%, and 25%, respectively, in 124 node-negative patients. Survival analysis indicated that OSNA positive stage II CRC patients had a shorter 3-y disease-free survival rate than OSNA negative stage II CRC patients. In 2017, AJCC TNM staging (the 8th version) revised the definition of LN metastasis in colon cancer and it is stated that micrometastasis should be considered as a standard LN metastasis. To our surprise, this revision was based on a meta-analysis to which our previous study on micrometastasis largely contributed. The remaining questions to be addressed are how to find micrometastases efficiently and whether postadjuvant chemotherapy is effective to prevent disease recurrence and to contribute to longer survival.

    Abstract Identifying protective adaptive immune responses against human immunodeficiency virus type 1 (HIV-1), mainly comprising CD8+ cytotoxic T lymphocyte (CTL) and neutralizing antibody (NAb) responses, is crucial for understanding in vivo mechanisms of viral persistence and developing prophylactic/intervention strategies. In HIV-1 and pathogenic simian immunodeficiency virus (SIV) infections, CTL responses play the canonical role in primary viral replication control, whereas NAb responses are impaired. This NAb impairment in early infection conversely highlights the necessity of elucidating anti-HIV/SIV antibody defense/induction mechanisms, and one approach to analyze the impact of NAbs on HIV/SIV infection is passive immunization. We have analyzed a simian AIDS model of highly pathogenic SIVmac239-infected rhesus macaques, and characterized that a single acute-phase passive infusion of SIV-specific polyclonal NAbs drives a synergistic qualitative boosting of virus-specific T-cell responses, resulting in sustained SIV replication control. This in vivo functional augmentation of virus-specific T cells by NAbs in the SIV model provides insights into the design of protective immunity against HIV-1 infection.

    Abstract This book discusses contemporary film in all the main countries of Southeast Asia, and the social practices and ideologies which films either represent or oppose. It shows how film acquires signification through cultural interpretation, and how film also serves as a site of contestations between social and political agents seeking to promote, challenge, or erase certain meanings, messages or ideas from public circulation. A unique feature of the book is that it focuses as much on films as it does on the societies from which these films emerge: it considers the reasons for film-makers taking the positions they take; the positions and counter-positions taken; the response of different communities; and the extent to which these interventions are connected to global flows of culture and capital
