Study protocol of the TRICOLORE trial: a randomized phase III study of oxaliplatin-based chemotherapy versus combination chemotherapy with S-1, irinotecan, and bevacizumab as first-line therapy for metastatic colorectal cancer

Background Metastatic colorectal cancer carries a poor prognosis and cannot be cured by currently available therapy. Chemotherapy designed to prolong survival and improve the quality of life (QOL) of patients is the mainstay of treatment. Standard regimens of FOLFOX/bevacizumab and CapeOX/bevacizumab can cause neurotoxicity, potentially disrupting treatment. The results of 3...

Chfr expression is downregulated by CpG island hypermethylation in esophageal cancer

Cell cycle progression is monitored by checkpoint mechanisms to ensure the integrity of the genome and the fidelity of sister chromatid separation. Failure of such checkpoint functions results in genomic instability, a condition that predisposes cells to neoplastic transformation and tumor progression. Recently, Scolnick and Halazonetis defined a new mitotic checkpoint that acts...

Severe Dextran-Induced Anaphylactic Shock during Induction of Hypertension-Hypervolemia-Hemodilution Therapy following Subarachnoid Hemorrhage

Dextran is a colloid effective for volume expansion; however, a possible side effect of its use is anaphylaxis. Dextran-induced anaphylactoid reaction (DIAR) is a rare but severe complication, with a small dose of dextran solution sufficient to induce anaphylaxis. An 86-year-old female who underwent clipping for a ruptured cerebral aneurysm was admitted to the intensive care unit...

Dorsal-ventral midline signaling in the developing Drosophila eye

Atsushi Sato Andrew Tomlinson Boundaries between different cell types play key roles in many developmental patterning processes. They can be established by various mechanisms, and signaling between

Translocated duplication of a targeted chromosomal segment enhances gene expression at the duplicated site and results in phenotypic changes in Aspergillus oryzae

BackgroundTranslocated chromosomal duplications occur spontaneously in many organisms; segmental duplications of large chromosomal regions are expected to result in phenotypic changes because of gene dosage effects. Therefore, experimentally generated segmental duplications in targeted chromosomal regions can be used to study phenotypic changes and determine the functions of...

Efficacy and safety of capecitabine plus cisplatin in Japanese patients with advanced or metastatic gastric cancer: subset analyses of the AVAGAST study and the ToGA study

BackgroundCapecitabine plus cisplatin (XP) is recognized as one of the global standard first-line chemotherapy regimens for patients with metastatic gastric cancer (mGC). Recent multinational phase III trials in mGC have been conducted with XP as the control arm, although no data on XP in Japanese patients with mGC have been published to date. The AVAGAST (XP ± bevacizumab in mGC...

A phase II study of doxifluridine and docetaxel combination chemotherapy for advanced or recurrent gastric cancer

Background The aim of this study was to establish the efficacy and safety of doxifluridine and docetaxel for patients with advanced or recurrent gastric cancer. Methods The regimen consisted of oral administration of doxifluridine 533 mg/m2 per day on days 1–14 and an intravenous infusion of docetaxel 50 mg/m2 on day 8. The primary endpoint was the overall response rate. The...

Effectiveness of doxifluridine (5′-DFUR)/docetaxel against advanced/recurrent gastric cancer showing resistance to various anticancer drug regimens

Peritoneal metastasis as a predictive factor for nab-paclitaxel in patients with pretreated advanced gastric cancer: an exploratory analysis of the phase III ABSOLUTE trial

BackgroundIn the ABSOLUTE trial, weekly nanoparticle albumin-bound paclitaxel (w-nab-PTX) showed non-inferiority to weekly solvent-based paclitaxel (w-sb-PTX) for overall survival (OS). Thus, w-nab-PTX might be an option for second-line chemotherapy in advanced gastric cancer (AGC). However, predictive factors for efficacies of these agents have not been evaluated.MethodsPatients...

Design of fusion technique-based mining engine for smart business

Keys to successful implementation of smart business require a wide spectrum of domain knowledge, experts, and their correlated experiences. Excluding those external factors—which can be collected by well-deployed sensors—being aware of user (or consumer) has the highest priority on the to-do-list. The more user is understood, the more user can be satisfied from an intuitive point...

The association between masked hypertension and waist circumference as an obesity-related anthropometric index for metabolic syndrome: the Ohasama study

Masked hypertension has been proven to be associated with an increased risk for cardiovascular diseases. The purpose of this study was to examine the direct associations of obesity-related anthropometric indices, including waist circumference, with masked hypertension. Participants in this population-based survey included 395 residents (35 years) of Ohasama, a rural Japanese...

Proposal of a Risk-Stratification System for the Japanese Population Based on Blood Pressure Levels: The Ohasama Study

The aim of the present study was to propose a risk-stratification system based on self-measurement of home blood pressure (HBP) as well as casual-screening BP (CBP) in relation to Japanese Society of Hypertension Guidelines for the Management of Hypertension (JSH 2004). For 4 weeks, the subjects measured their HBP while seated every morning within 1 h after awaking, after having...

The Effect of Synthetic C-Reactive Protein on the In Vitro Immune Response of Human PBMCs Stimulated with Bacterial Reagents

Synthetic C-reactive protein (CRP) rescues mice from lethal endotoxin shock or bacterial infection by suppressing tumor necrosis factor (TNF-α), but in turn, enhances Kupffer cell phagocytic activity. We herein assessed the influence of CRP in human peripheral blood mononuclear cells (PBMCs). When human PBMCs were stimulated in vitro with penicillin-treated Streptococcus pyogenes...

Potent Antimalarial and Transmission-Blocking Activities of Centanamycin, a Novel DNA-Binding Agent

Most treatments for malaria target the blood stage of infection in the human host, although few can also block transmission of the parasite to the mosquito. We show here that the compound centanamycin is very effective against blood-stage malarial infections in vitro and in vivo and has profound effects on sexual differentiation of the parasites in mosquitoes. After drug...
