Abstract
Purpose: Although adolescent and young adult (AYA) cancer patients are digital natives and have high digital communication needs, previous studies of screening tools for AYAs have primarily used paper when measuring patient-reported outcomes (PROs). There are no reports on using an electronic PRO (ePRO) screening tool with AYAs. This study evaluated the feasibility of such a tool in clinical settings, and assessed the prevalence of AYAs' distress and supportive care needs. Methods: An ePRO tool based on the Distress Thermometer and Problem List (DTPL)-Japanese (DTPL-J) version for AYAs was implemented in a clinical setting for 3 months. To determine the prevalence of distress and need for supportive care, descriptive statistics were calculated for participant characteristics, selected items, and Distress Thermometer (DT) scores. Response rates, referral rates to an attending physician and other experts, and time required to complete PRO tools were assessed to evaluate feasibility. Results: From February to April 2022, 244 (93.8%) of 260 AYAs completed the ePRO tool based on the DTPL-J for AYAs. Based on a DT cutoff of ≥5, 65 of 244 patients (26.6%) had high distress. Worry (n = 81, 33.2%) was the most frequently selected item. Primary nurses referred 85 (32.7%) patients to an attending physician or other experts. The referral rate resulting from ePRO screening was significantly higher than that after PRO screening (χ2(1) = 17.99, p < 0.001). The average response time did not differ significantly between ePRO and PRO screening (p = 0.252). Conclusion: This study suggests the feasibility of an ePRO tool based on the DTPL-J for AYAs.

Abstract
Purpose: Adolescent and young adult (AYA) patients with cancer have few opportunities to connect with patients of the same generation while hospitalized. Although anxiety is frequently reported by them, there are no reports on the psychological effectiveness of an in-hospital patient support program based on peer support. This study aimed to evaluate the effectiveness of a program, termed Adolescent and Young Adult Hiroba (AYA Hiroba), for anxiety in AYA patients with cancer. Methods: This single-center, prospective, observational study in 24 AYA patients with cancer was conducted at the National Cancer Center Hospital in Japan. The Hospital Anxiety and Depression Scale-Anxiety (HADS-A) was used to evaluate the primary outcome, anxiety. The Distress Thermometer (DT) was used to evaluate the secondary outcome, distress. The two outcomes were assessed before and after participation in AYA Hiroba. The Net Promoter Score (NPS) was used to evaluate satisfaction after participation in AYA Hiroba. Participants' free-text descriptions of the program were categorized according to similarities and differences. Results: The HADS-A and DT scores were significantly lower after the program than before (p < 0.001), as was the percentage of AYA patients with cancer with high distress (p = 0.04). The NPS was 27, which was lower than the value of 52 obtained in our previous study. Requests and suggestions to improve the program were grouped into three categories: content, facilitation, and online connection environment. Conclusion: This study suggests the preliminary effectiveness of the in-hospital peer support program for anxiety in AYA patients with cancer. The Clinical Trial Registration number: UMIN000045779.

Abstract
Postoperative delirium is an important issue in cancer patients, affecting surgical outcomes and the quality of life. Ramelteon is a melatonin receptor agonist with high affinity for MT1 and MT2 receptors. Clinical trials and observational studies in Japan, including in surgical cancer patients, have shown efficacy of ramelteon in delirium prevention, with no serious safety concerns. However, clinical trials from the USA have reported conflicting results. A Japanese phase II study investigated the efficacy and safety of ramelteon for delirium prevention following gastrectomy in patients aged ≥75 years, with findings suggesting the feasibility of a phase III trial. The aim of this multi-centre, double-blind, randomized placebo-controlled phase III trial is to evaluate the effectiveness and safety of oral ramelteon for postoperative delirium prevention in cancer patients aged ≥65 years as advanced medical care. The trial protocol is described here.

Abstract
Background Though the effectiveness of behavioral activation (BA) for patients with cancer and depression were reported, there is no evidence in Japan. Objectives This study aimed at examining the feasibility and preliminary effectiveness of BA for patients with cancer and depression in Japan. Methods This pre-post study without a control group was conducted in patients with cancer and depression in Japan. The program completion rate was compared with those of previous studies to examine feasibility. To examine the preliminary effectiveness, outcomes were evaluated four times: before and immediately after the program, and two weeks and three months after the program ended. The primary outcome was the remission rate of depression using the 17-item version of the GRID Hamilton Rating Scale for Depression (HAMD17). Secondary outcomes were self-reported depression, anxiety, quality of life, changes in behavior, values, and perceived reward of activity and environmental factors. Pre- and post-program data were compared using paired-samples t-tests, and data obtained at four time points were analyzed using one-way repeated-measures analysis of variance. Results Of the 68 patients recruited from February 2018 to January 2022, 32 were registered. The completion rate was 75% (24/32), which was similar to previous studies. The total HAMD17 score significantly improved after the program. The remission rate of depression was 62.5% (20/32), which was above the defined threshold value (30%). All but two secondary outcomes significantly improved after the program (p < 0.05). Conclusions The feasibility and preliminary effectiveness of BA for patients with cancer and depression in Japan were suggested. The Clinical Trial Registration number: UMIN 000036104.

Abstract
BACKGROUND Though behavioral activation (BA) has been shown to be effective for depression, evidence in patients with advanced cancer has not been established. This study aimed to examine the effectiveness of a BA program on depression in this population. METHODS A randomized controlled trial with a wait-list control group (waiting group) of 38 patients with advanced cancer and depression will be conducted at three sites in Japan. The BA program consists of seven sessions. Outcome measures will be evaluated at three times in the intervention group; at the entry, at the end of the intervention and 4 months after the end of the intervention and four times in the waiting group: at the entry, before the intervention, at the end of the intervention, and 4 months after the end of the intervention. Primary outcome is Beck Depression Inventory-II (BDI-II) score. To examine the main effect of the intervention, two-way repeated measures analysis of variance (ANOVA) will be conducted, with timing and intervention status as the independent variables and BDI-II score as the dependent variable. One-way repeated measures ANOVA will be conducted to combine data from the intervention and control groups and examine changes in BDI-II scores by timing in both groups. Secondary endpoints (anxiety, quality of life, spirituality, degree of behavioral activation, value, and pain) will be evaluated with rating scales. Two-way repeated measures ANOVA will be conducted to examine whether there are differences between the groups before and after the intervention, with timing and intervention status as the independent variables and scores on each rating scale as the dependent variables. DISCUSSION This multicenter randomized controlled trial is the first study to assess the effectiveness of BA on depression in patients with advanced cancer. Our findings will provide evidence about the effectiveness of BA on depression and provide an intervention option that is acceptable and feasible for the treatment of depression in this population. The results of this study will lead to improved mood and rebuilding to regain life purpose and value in this vulnerable population.

Abstract
Adolescent and young adult (AYA) patients with cancer have few opportunities to interact with peers in their lives. To meet peers safely during the coronavirus disease 2019 (COVID-19) pandemic, a hospital-based online patients support program called Online AYA Hiroba was launched for AYA patients with cancer and held regularly by the National Cancer Center Hospital in Japan. This retrospective study suggested the degree of satisfaction with this program and issues about facilitating the sessions that are unique to the online environment. Our findings potentially contribute to the establishment of a hospital-based online patients support program for AYA patients with cancer at other hospitals.

Abstract
Cancer patients in adolescents and young adults (AYA) generation aged 15-39 years have various psychosocial needs during their treatment course such as school enrollment, finding employment, marriage, and fertility. It is difficult for medical professionals to gain experience related to providing medical care and consultation support to these kinds of AYA generation cancer patients. There is a need to provide information and establish both support and medical care systems that are able to meet the diverse needs unique to this generation. This review will explain how to launch an AYA support team (AST). We have worked and established the AST since 2016, which is medical care teams that provide support according to the life stage of each individual patient and build a multidisciplinary AYA generation patient support system. The team-building process consisted of two main projects: building and enlarging multidisciplinary team and establishing screening process of psychosocial needs of AYA generation patients. Multidisciplinary healthcare professionals got involved in the AST with already-existing patient support functions in our center: the patient support center, which is an outpatient department and the palliative care team, which is an inpatient interdepartmental team. The AST systematically finds patients in need of assistance and offers them support as a multidisciplinary team. The AST also established a procedure that systematically gathers information about the needs of patients by using a screening tool. In addition, the AST provides the following specialized services: reproductive medicine, supporting cancer patients with children, employment support, and peer support. The AST has been established and sophisticatedly worked. It can flexibly provide various psychosocial support services. This review will explain how to launch an AST.

Abstract
A 73-year-old woman with atrial fibrillation treated with rivaroxaban was hospitalized for nephrotic syndrome. After discontinuation of rivaroxaban to lower the risk of hemorrhagic events, a renal biopsy was performed. Rivaroxaban was scheduled to resume a week after the biopsy to prevent renal hemorrhaging. However, she developed acute brachial arterial embolic occlusion and mural thrombosis in the abdominal aorta before resuming rivaroxaban. If immune-mediated renal diseases are suspected in anticoagulated patients at a risk of thrombotic events, physicians should consider initiating glucocorticoid therapy without a renal biopsy in order to avoid hemorrhagic and thrombotic events.

Abstract
Adolescent and young adult (AYA) cancer patients have few opportunities to interact with peers in the hospital. AYA Hiroba, a peer support system for AYA cancer patients, was launched and held regularly at the National Cancer Center Hospital in Japan. This questionnaire survey was conducted to investigate the degree of satisfaction and opinions of AYA cancer patients regarding this program. Participants reported that the content was satisfying and useful. Their impressions suggested that AYA Hiroba is potentially effective for promoting interaction with the same generation, change in mood, and acquisition of information.

Abstract
We report on the frozen-spin polarized hydrogen-deuteride (HD) targets for photoproduction experiments at SPring-8/LEPS. Pure HD gas with a small amount of ortho-H2 (∼0.1%) and a very small amount of para-D2 (∼0.001%) was liquefied and solidified by liquid helium. The temperature of the produced solid HD was reduced to about 30 mK with a dilution refrigerator. A magnetic field (17 T) was applied to the HD to grow the polarization with the static method. After the aging of the HD at low temperatures in the presence of a high-magnetic field strength for three months, the polarization froze. Almost all ortho-H2 molecules were converted to para-H2 molecules. Most remaining para-D2 molecules were converted to ortho-D2 molecules. The para-H2 and ortho-D2 molecules exhibited weak spin interactions with the HD. If the concentrations of the ortho-H2 and para-D2 were reduced appropriately at the beginning of the aging process, the aging time can be shortened. We have developed a new nuclear magnetic resonance (NMR) system to measure the relaxation times (T1) of the 1H and 2H nuclei with two frequency sweeps at the respective frequencies of 726 MHz and 111 MHz and succeeded in the monitoring of the polarization build-up at decreasing temperatures from 600 mK to 30 mK at 17 T. Automatic NMR measurements with the frequency sweeps enabled us to omit the use of a manual tuning circuit and to remove magnetic field sweeps with eddy current heat. This technique enables us to optimize the concentration of the ortho-H2 and to efficiently polarize the HD target within a shortened aging time.

Abstract
We measured missing mass spectrum of the ^{12}C(γ,p) reaction for the first time in coincidence with potential decay products from η^{'} bound nuclei. We tagged an (η+p) pair associated with the η^{'}N→ηN process in a nucleus. After applying kinematical selections to reduce backgrounds, no signal events were observed in the bound-state region. An upper limit of the signal cross section in the opening angle cosθ_{lab}^{ηp}<-0.9 was obtained to be 2.2 nb/sr at the 90% confidence level. It is compared with theoretical cross sections, whose normalization ambiguity is suppressed by measuring a quasifree η^{'} production rate. Our results indicate a small branching fraction of the η^{'}N→ηN process and/or a shallow η^{'}-nucleus potential.

Abstract
Background Behavioral activation therapy (BAT) directly addresses activities that individuals value most highly, and may be easily applicable to cancer patients. However, there is no established evidence of the use of BAT in this population. In this study, we examined the possibility of a BAT program for depression and anxiety in cancer patients. Case presentation We retrospectively reviewed the medical records of cancer patients with each of the following characteristics: 1) were outpatients or inpatients visiting the psycho-oncology division of the National Cancer Center Hospital in Japan; 2) met criteria for Major Depressive Disorder or Adjustment Disorders; and 3) participated in a BAT program. The primary outcome was the program completion percentage. Secondary outcomes were self-reported depression severity (Patient Health Questionnaire-9 (PHQ-9) score), anxiety disorder status (Generalized Anxiety Disorder-7 (GAD-7) score), and clinical improvement (Clinical Global Impression-Improvement (CGI-I) score) after the program. We analyzed both depression and anxiety by the matched paired t-test. Ten patients participated in the program, and nine completed it. One dropped out due to cognitive impairment secondary to brain metastasis. Both the PHQ-9 scores (pre: 14.4 (SD, 6.1); post: 5.1 (SD, 5.8)) and the GAD-7 scores (pre: 11.9 (SD, 4.9); post: 4.7 (SD, 5.5)) significantly improved after the program (PHQ-9: P = 0.0014; GAD-7: P = 0.0004). CGI-I scores ranged from 1 to 3, and all subjects except the patient who dropped out improved clinically. Among the ten patients, three distinctive cases could be observed as follows. Case 1; a 45-year-old housewife with breast cancer who did not agree to take antidepressants because of concerns about the side effects achieved remission without antidepressants and began to live an active life. Case 4; a 66-year-old housewife was so shocked after endometrial cancer diagnosis that she was absent-minded and her compliance with the assigned homework was poor, therefore, her depression did not improve much. Case 9; a 62-year-old man with laryngeal cancer who had recurrent anxiety. Increased business activity, on which he put great value, gradually allowed him to be able to live his life actively without concerns. Conclusions This study suggests that BAT would be effective for the depression and anxiety of cancer patients.

Abstract
Differential cross sections and photon-beam asymmetries for the γ[over →]p→π^{-}Δ^{++}(1232) reaction have been measured for 0.7<cosθ_{π}^{c.m.}<1 and E_{γ}=1.5-2.95 GeV at SPring-8/LEPS. The first-ever high statistics cross-section data are obtained in this kinematical region, and the asymmetry data for 1.5<E_{γ}(GeV)<2.8 are obtained for the first time. This reaction has a unique feature for studying the production mechanisms of a pure uu[over ¯] quark pair in the final state from the proton. Although there is no distinct peak structure in the cross sections, a non-negligible excess over the theoretical predictions is observed at E_{γ}=1.5-1.8 GeV. The asymmetries are found to be negative in most of the present kinematical regions, suggesting the dominance of π exchange in the t channel. The negative asymmetries at forward meson production angles are different from the asymmetries previously measured for the photoproduction reactions producing a dd[over ¯] or an ss[over ¯] quark pair in the final state. Advanced theoretical models introducing nucleon resonances and additional unnatural-parity exchanges are needed to reproduce the present data.

Abstract
Bevacizumab, an inhibitor of vascular endothelial growth factor, is approved for the treatment of various cancers, but the incidence of proteinuria as a side effect has been reported to be 2-64%. We report a case of renal impairment due to thrombotic microangiopathy (TMA) accompanied with glomerular subendothelial deposition of IgA resulting from bevacizumab administration. A 57-year-old female with advanced breast cancer, to whom bevacizumab had been administered from October 2012, developed proteinuria and epithelial casts in her urine about a month later. Serum creatinine remained at 0.7-0.8 mg/dL until June 2013, but gradually increased to 1.3 mg/dL in September. She was referred to our hospital because her renal function had not improved despite termination of bevacizumab, and a renal biopsy was performed in October. At that time, the levels of proteinuria, serum creatinine and serum IgA were high at 1.3 g/g x Cr, 1.6 mg/dL and 430 mg/dL, respectively. Histological examinations showed prominent IgA deposits in the subendothelial area and glomerular infiltration of CD68 positive cells in addition to features of TMA, such as narrowed glomerular capillary lumina and double contours of the basement membranes. In consideration of her clinical history, a diagnosis of bevacizumab-induced TMA was made. Through follow-up care without readministration of bevacizumab, epithelial casts in her urine disappeared, and proteinuria decreased to 0.62 g/g x Cr in November. Serum creatinine remains high at around 1.3 mg/dL, but has not elevated further. Serum IgA gradually decreased and reached 289 mg/dL in April 2014. TMA due to bevacizumab described in several other reports was also accompanied by glomerular IgA deposition, thus a differential diagnosis of IgA nephropathy is required. TMA was recently added to a section of "significant adverse effects" in the package insert of bevacizumab. Nephrologists should be fully aware of this drug-induced nephropathy.

Abstract
Neospora caninum is an Apicomplexan parasite that causes repeated abortion and stillbirth in cattle. The aim of this study was to clone the gene encoding the N. caninum orthologue (NcBAG1) of the Toxoplasma gondii bradyzoite-specific protein TgBAG1 and characterize its expression pattern in the parasite. Isolation of the full-length 684-bp gene revealed that it shared 78.3% sequence similarity with TgBAG1. NcBAG1 encodes a predicted protein of 227 amino acids with 80.3% similarity to TgBAG1. A putative signal peptide sequence and an invariant GVL motif characteristic of small heat-shock proteins were identified in the predicted N. caninum amino acid sequence. We expressed the NcBAG1 gene as a recombinant glutathione S-transferase fusion protein (rNcBAG1) in Escherichia coli and used the purified 60 kDa protein to obtain a monoclonal antibody (Mab). rNcBAG1 reacted to Mabs specific for NcBAG1 and TgBAG1. No reaction between the NcBAG1 Mab and N. caninum tachyzoites was observed. Although the predicted molecular mass of NcBAG1 is 25 kDa, Western blot analysis of parasite lysates using the NcBAG1 Mab revealed a cross-reactive protein of approximately 30 kDa. Additionally, immunofluorescence assays using the tachyzoite-specific Mab for NcSAG1 and the bradyzoite-specific Mab for TgBAG1 or NcSAG4 revealed NcBAG1-specific expression in bradyzoites in cultures exposed to sodium nitroprusside, a reagent that increases the frequency of bradyzoites. Interestingly, the NcBAG1 protein was identified in the cytoplasm of the bradyzoite-stage parasites. This preliminary analysis of the NcBAG1 gene will assist investigations into the role of this protein in N. caninum .

Abstract
INTRODUCTION With the aim of identifying metastases-related genes in gastric cancer, we performed a broad analysis of differential gene expression between low-metastatic parental cell lines and established highly metastatic sublines. MATERIALS AND METHODS We established novel cell lines, AZ-H5c, NUGC-3H5, and TMK-1H7, with a high potential of liver metastasis, and AZ-P7a, NUGC-3P4T, and TMK-1P4a, with a high potential of peritoneal metastasis. These cell lines were derived from low-metastatic parental AZ-521, NUGC-3, and TMK-1 cell lines, respectively. Furthermore, to investigate different levels of gene expression implicated in metastatic potentials in gastric cancer, we investigated approximately 2000 expressed genes in each cell line using a DNA microarray. RESULTS Varieties of genes were up-regulated or down-regulated in highly metastatic liver and peritoneal cell lines. Fifty-eight genes, including the transferrin receptor, ras-related rho, and osteopontin, and 22 genes, including apolipoprotein E and inhibin A-submit, were up-regulated and down-regulated in two or three liver metastatic sublines. On the other hand, 19 genes, the transferrin receptor, c-fos, and RANTES, and 26 genes, including MAC25, PISSLRE, and RNA polymerase, were up-regulated and down-regulated in two or three peritoneal metastatic sublines. CONCLUSION How gene expression is implicated in gastric cancer metastasis has never been thoroughly explained, and further studies are necessary to understand the involvement of genes in cancer metastasis more thoroughly. We hope that our highly metastatic liver and peritoneal experimental models are helpful for further study and gene therapy of human gastric cancer.

Abstract
We established the novel sublines HPC-1H5, HPC-3H4, HPC-4H4, and Panc-1H5, which have a high potential of liver metastasis, and HPC-1P5a, HPC-3P4a, HPC-4P4a, and Panc-1P5a, which have a high potential of peritoneal dissemination, derived from low metastatic HPC-1, HPC-3, HPC-4, and Panc-1cell lines, respectively. To clarify the molecular mechanisms of cancer metastasis and of the different levels of gene expression in a variety of metastatic potentials in pancreatic cancer, we performed a broad analysis of differential gene expression analysis between parental cell lines and metastatic sublines. In comparison with the parental cell lines, 65 and 36 genes were overexpressed and underexpressed in highly liver-metastatic sublines. On the other hand, 43 and 45 genes were overexpressed and underexpressed in highly peritoneal-metastatic sublines. uPAR and Serin protease were overexpressed, and E2A and IGF1R were underexpressed in both metastatic sublines. Hierarchical clustering analysis revealed 22 genes classifying liver, peritoneal metastatic sublines and low-metastatic parental cell lines. These genes might be targeted genes separating those two major metastatic forms after surgery. A greater number of cell line samples and more genes will have to be utilized in future studies in order to understand the involvement of genes in cancer metastasis more thoroughly. However, these results will help to clarify the molecular mechanisms of pancreatic cancer metastasis.

Abstract
To elucidate metastasis mechanisms, we established a Panc-1H5 subline with a highly liver metastatic cell line and a Panc-1P4a with a highly peritoneal metastatic cell line, which were sequentially selected from the parental pancreatic cancer cell line Panc-1. Using these three cell lines, we investigated several biological properties and mRNA levels of differentially-expressed genes involved in cancer metastasis with a cDNA macroarray. The tumorigenicity, motile activity, adhesive activity and cytokine production of metastatic sublines were higher than those of parental Panc-1 cells. Particularly, in Panc-1H5 cells, adhesive activity to the extracellular matrix and angiogenetic factors increased, whereas in Panc-1P4a cells, motile activity was extremely enhanced compared with Panc-1 cells. Histopathological findings for the three cell lines were the same. In cDNA macroarray analysis of Panc-1H5 cells, 11 genes were up-regulated and 20 genes were down-regulated compared with parental Panc-1 cells. In Panc-1P4a cells, 7 genes were up-regulated and 13 genes were down-regulated compared with parental Panc-1 cells. This study provides a demonstration of global gene expression analysis of pancreatic cancer cells with liver and peritoneal metastasis and these results provide new insight into the study of human pancreatic cancer metastasis.

Abstract
To investigate the contribution of beta-catenin to the development of gallbladder carcinoma, genetic alteration in beta-catenin gene, ctnnb-1 and subcellular localization of beta-catenin protein were searched. Mutational analysis of exon 3 in ctnnb-1, which encodes the serine/threonine residues for GSK3beta phosphorylation sites, was performed for 21 gallbladder carcinomas affected with/without the pancreaticobiliary malunion, PBM, and 6 non-cancerous tissues affected with PBM. We also analyzed subcellular localization of beta-catenin protein in all cases immunohistochemically. Nucleotide sequencing analysis revealed that none of them carried mutations that altered amino acid residues in the potential GSK3beta phophorylation sites, but one nucleotide substitution was found. We also analyzed subcellular localization of beta-catenin protein in all cases immunohistochemically, and confirmed its accumulation in both the nucleus and cytoplasm in 10 out of 21 cancer tissues, while the non-cancerous tissues which were affected with PBM and histologically diagnosed as hyperplasia or dysplasia displayed intense membranous staining. A significant correlation between cytoplasmic or nuclear beta-catenin immunoreactivity and clinicopathological status of gallbladder carcinomas was found, especially in the poorer histological differentiation grade(p < 0.05). In conclusion our results suggested that beta-catenin alteration might be a minor contributor to the development of gallbladder carcinomas through abnormal Wnt-wingless signalling, however, decreased membranous expression of beta-catenin might be correlated to carcinoma progression through loss of cell adhesive function in E-cadherin-catenin fashion.

Abstract
To investigate the contribution of beta-catenin to the development of carcinoma of the ampulla of Vater, genetic alterations of beta-catenin gene, CTNNB-1 were searched. Mutational analysis of exon3 in CTNNB-1, which encodes the serine/threonine residues for GSK-3beta phosphorylation sites, was performed on 21 cases of carcinoma of the ampulla of Vater, by means of polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) followed by nucleotide sequencing. We found one deleted mutation at codon 32 to approximately 65 in one case of carcinoma of the ampulla of Vater. We also analyzed subcellular localization of beta-catenin protein in all cases immunohistochemically, and confirmed its accumulation in the nucleus in four cases including in a CTNNB-1 mutated one. This is the first study to show CTNNB-1 mutation and beta-catenin expression in carcinoma of the ampulla of Vater. These results suggested that abnormal Wnt-wingless signaling and in particular beta-catenin alteration caused accumulation of beta-catenin, which might partially contribute to the development of carcinoma of the ampulla of Vater.

Abstract
Interferon-alpha (IFN-alpha) has a number of therapeutic applications in the treatment of various human cancers and diseases of viral origin. IFN-alpha includes several subtypes, and little has been reported on the biologic properties of the individual subtypes. Here, we report on the individual antitumor effects of five IFN-alpha subtypes, alpha1, alpha2, alpha5, alpha8, and alpha10, against six renal cell carcinoma (RCC) cell lines in vitro. Among the subtypes, IFN-alpha8 most potently inhibited cell proliferation and delayed the G(1)/S transition. Synergistic induction of apoptosis was shown in two of the RCC cell lines when treated with the combination of IFN-alpha and IFN-gamma rather than with either IFN-alpha or IFN-gamma alone. IFN-alpha8 was most effective in the induction of apoptosis when combined with IFN-gamma. In addition, IFN-alpha8 had the strongest ability to upregulate HLA class II antigen expression in the subtypes examined. These data indicate that subtypes of IFN-alpha have disparate antitumor effects in vitro, and in vitro distinctions among the IFN-alpha subtypes should be appreciated more in clinical application.

Abstract
In higher plants, developmental phase changes are regulated by a complex gene network. Loss-of-function mutations in the EMBRYONIC FLOWER genes (EMF1 and EMF2) cause Arabidopsis to flower directly, bypassing vegetative shoot growth. This phenotype suggests that the EMF genes play a major role in repression of the reproductive program. Positional cloning of EMF2 revealed that it encodes a zinc finger protein similar to FERTILIZATION-INDEPENDENT SEED2 and VERNALIZATION2 of Arabidopsis. These genes are characterized as structural homologs of Suppressor of zeste 12 [Su(z)12], a novel Polycomb group gene currently identified in Drosophila. In situ hybridization studies have demonstrated that EMF2 RNA is found in developing embryos, in both the vegetative and the reproductive shoot meristems, and in lateral organ primordia. Transgenic suppression of EMF2 produced a spectrum of early-flowering phenotypes, including emf2 mutant-like phenotype. This result confirms the role of EMF2 in phase transitions by repressing reproductive development.

Abstract
Here we report on the antiviral effects of two commercially available natural interferon-alpha (IFN-alpha) preparations, their subtype compositions, and the effects of combinations of pairs of the subtypes on virally infected cells. Our results show that the antiviral effects of these preparations depend on the target cell and on the infecting virus. The component subtypes vary with the preparations, and combinations of pairs of IFN-alpha subtypes may have synergistic or competitive effects. Our results suggest that optimal preparations of synergistically acting subtypes may provide more therapeutic benefit to patients.

Vascular endothelial growth factor (VEGF)-C, one of several members of the VEGF family, is a relatively specific lymphangiogenic growth factor. VEGF receptor (VEGFR)-3 (or Flt4) is a VEGF-C receptor with expression restricted to lymphatic endothelial cells. Since the mechanisms by which carcinoma cells metastasize to lymph nodes remain unclear, we constructed a VEGF-C transfectant (AZ-VEGF-C) from the AZ521 human gastric carcinoma cell line, which ordinarily shows little nodal metastatic potential and little VEGF-C expression. We orthotopically implanted transfected tumor cells into the stomachs of nude mice. The number of mice developing lymph node metastases and the number of lymph node metastases per mouse with nodal metastases were higher than with implants of mock-transfected control cells. Specifically, percentages of mice with lymph node metastases were 95.5% (21/22) for AZ-VEGF-C and 29.4% (5/17) for controls (P<0.01), while mean numbers of involved lymph nodes were 3.76 for AZ-VEGF-C and 1.00 for controls (P<0.01). No difference was found between AZ-VEGF-C and controls regarding cell growth and chemotactic responses in vitro, or in volumes of tumors arising from implanted cells. When we performed immunohistochemical staining for VEGFR-3 in these tumors to investigate lymphangiogenesis by VEGF-C, the number of vessels stained for VEGFR-3 in tumors and surrounding tissues was higher for AZ-VEGF-C than for controls. VEGFR-3-positive vessels occupied 14.9/1000 of microscopically examined areas for AZ-VEGF-C, but only 1.30/1000 for controls (P<0.001). Our results suggest that VEGF-C is a specific lymphangiogenic growth factor with an important role in lymph node metastasis.

Abstract
The present paper aimed at learning the effects of two different levels of air permeability and moisture absorption on clothing microclimate and subjective sensation in sedentary women. Three kinds of clothing ensemble were investigated: 1) polyester clothing with low moisture absorption and low air permeability (A clothing); 2) polyester clothing with low moisture absorption and high air permeability (B clothing); and 3) cotton clothing with high moisture absorption and high air permeability (C clothing). After 20 min of dressing time, the room temperature and humidity began to rise from 27 degrees C and 50% rh to 33 degrees C and 70% rh over 20 min, and it was maintained for 30 min (Section I); it then began to fall to 27 degrees C and 50% rh over 20 min, and it was maintained there for 20 min (Section II). The subject sat quietly on a chair for 110 min. The main findings are summarized as follows: 1) The clothing surface temperature was significantly higher in C clothing than in B clothing during section I, but it was significantly higher in B clothing than in C clothing during section II. 2) Although the positive relationship between the microclimate humidity and forearm sweat rate was significantly confirmed in all three kinds of clothing, the microclimate humidity at the chest for the same sweat rate was lower in C clothing than in A and B clothing. These results were discussed in terms of thermal physiology.

Abstract
Eight locally advanced breast cancer patients were treated with neoadjuvant intraarterial high-dose chemotherapy (epirubicin) plus MPA combined with autologous PBSCT. All patients completed the scheduled treatment, and there were no toxic deaths. Patients were treated with an escalating dose of epirubicin (370-480 mg) and cyclophosphamide (0-6000 mg). The rate of clinical response was 100%. The rate of good histologic response was 87.5% in the main tumor and 75% in diseased lymph nodes. The 2-year survival rate was 100%. Six patients were disease-free at the time of writing. This treatment resulted in higher rates of clinical and histologic response when compared with standard-dose intraarterial chemotherapy.

Abstract
The present paper aimed at determining the combined effects of two different levels of air permeability and moisture absorption, in terms of clothing microclimate and subjective sensation, in resting and exercising subjects at an ambient temperature of 27 degrees C, a relative humidity of 50% and an air velocity of 0.14 m s-1. Three kinds of clothing ensemble were investigated: (1) polyester clothing with low moisture absorption and low air permeability (A), (2) polyester clothing with low moisture absorption and high air permeability (B), and (3) cotton clothing with high moisture absorption and high air permeability (C). The subjects exercised for 10 min on a cycle ergometer at an intensity of 30% maximal oxygen uptake and then had a 10 min rest. This sequence was repeated four times. The main findings are summarized as follows: (1) The clothing microclimate humidity in the back area was significantly higher in A than in B, and in C than in B. (2) The clothing microclimate temperature in the chest area was significantly higher in B than in A, and in B than in C. (3) The clothing microclimate temperature in the back area was significantly higher in C than in B. (4) The clothing surface temperature was significantly higher in C than in B. (5) Although the positive relationships between the microclimate humidity and forearm sweat rate was significantly confirmed in all three kinds of clothing, the microclimate humidity at chest for the same sweat rate was lower in C than in A and B. (6) Although the positive relationships between subjective sensation and forearm sweat rates were significantly confirmed in all three kinds of clothing, the subjective discomfort seemed to be reduced more effectively in C than in A and B for the same sweat rate. These results were discussed in terms of thermal physiology and combined effects of air permeability and moisture absorbency of the fabrics.

Abstract
To accelerate gene isolation from plants by positional cloning, vector systems suitable for both chromosome walking and genetic complementation are highly desirable. Therefore, we developed a transformation-competent artificial chromosome (TAC) vector, pYLTAC7, that can accept and maintain large genomic DNA fragments stably in both Escherichia coli and Agrobacterium tumefaciens. Furthermore, it has the cis sequences required for Agrobacterium-mediated gene transfer into plants. We cloned large genomic DNA fragments of Arabidopsis thaliana into the vector and showed that most of the DNA fragments were maintained stably. Several TAC clones carrying 40- to 80-kb genomic DNA fragments were transferred back into Arabidopsis with high efficiency and shown to be inherited faithfully among the progeny. Furthermore, we demonstrated the practical utility of this vector system for positional cloning in Arabidopsis. A TAC contig was constructed in the region of the SGR1 locus, and individual clones with ca. 80-kb inserts were tested for their ability to complement the gravitropic defects of a homozygous mutant line. Successful complementation enabled the physical location of SGR1 to be delimited with high precision and confidence.

Abstract
IL-18 is a multifunctional cytokine playing various regulatory roles in the immune system including induced cytokine production. As a part of our ongoing studies on the molecular mechanisms of IL-18-induced IFN-gamma production, we have examined the transcriptional regulation of the IFN-gamma gene by IL-18 in a human myelomonocytic cell line, KG-1. On the basis of DNA/protein binding, we have determined an IL-18-inducible NF-kappa B binding site located at -786 to -776 of the IFN-gamma gene regulatory region (designated KBBsite). Transient transfection of promoter-reporter gene constructs revealed that the KBBsite is required for full IL-18-induced activation of the IFN-gamma gene transcription induced by IL-18. In addition, stable transformants of a dominant-negative form of the I kappa B alpha showed an inhibition of IL-18-dependent I kappa B alpha degradation, NF-kappa B activation, and expression of IFN-gamma. These results are the first to show the actual significance of the NF-kappa B pathway in the regulation of IFN-gamma gene expression by IL-18.

Abstract
The purpose of this present study was to compare the physiological effects of the hydrophilic and hydrophobic properties of the fabrics investigated in exercising and resting subjects at an ambient temperature of 30 degrees C and a relative humidity of 50% with and without wind. Three kinds of clothing ensemble were tested: wool and cotton blend with high moisture regain (A), 100% cotton with intermediate moisture regain (B), 100% polyester clothing with low moisture regain (C). The experiments were performed using seven young adult women as subjects. They comprised six repeated periods of 10-min exercise on a cycle ergometer at an intensity of 40% maximal oxygen uptake followed by 5 min of rest (20 min for the last rest). The experiments comprised two sessions. During session I (first three repetitions of exercise and rest) the subjects were exposed to an indifferent wind velocity and during session II (last three repetitions of exercise and rest) they were exposed to a wind velocity of 1.5 m x s(-1). Rectal temperature and skin temperatures at eight sites, pulse rate and clothing microclimate were recorded throughout the whole period. The main findings can be summarized as follows: rectal temperature during session II was kept at a significantly lower level in A than in B and C. Clothing microclimate humidity at the chest was significantly lower in A than in B and C during session II. Skin and clothing microclimate temperatures at the chest were significantly lower in A than in B and C during session II. Pulse rate was significantly higher in C than in A and B during sessions I and II. It was concluded that the hydrophilic properties of the fabrics studied were of physiological significance for reducing heat strain during exercise and rest especially when influenced by wind.

Abstract
The function of cytokine-induced neutrophil chemoattractant (CINC), which is the rat counterpart to human growth-related gene product belonging to the CXC chemokine subgroup, is based principally on neutrophil-specific chemotactic activity. In addition, we previously reported that plasma CINC was elevated during the period of small intestinal ischemia-reperfusion injury, and that there was a correlation between the degree of mucosal damage and the peak level of CINC after reperfusion, suggesting that CINC may play a major role in neutrophil infiltration into the rat small intestinal ischemia-reperfusion injury site. Thus, we investigated whether administration of anti-CINC monoclonal antibodies (mAbs) reduces small intestinal ischemia-reperfusion injury. Small intestine was subjected to ischemia for 3 h by occlusion of the anterior mesenteric artery with an atraumatic vascular clump. After infusion of anti-CINC mAbs or isotype-matched mAbs, the intestine was subjected to reperfusion. The pretreatment with anti-CINC mAbs attenuated ischemia-reperfusion injury in the small intestine, in association with the reduction of tumor necrosis factor-alpha and myeloperoxidase production, and resulted in the prolongation of survival. It is concluded that CINC plays an important role in the onset of rat small intestinal ischemia-reperfusion injury. In addition, blocking the action of CINC, namely, the neutrophil chemotactic activity, may be useful in preventing ischemia-reperfusion injury in the small intestine.

Abstract
Protein kinase C (PKC) is a key enzyme family involved in cellular signal transduction. The binding of endogenous diacyl glycerol (DAG) to the cysteine-rich domain (CRD) of PKC is associated with normal cell signaling and function. In contrast, the binding of exogenous phorbol esters to the CRD of PKC is considered to be a key initiating event in tumor promotion. Conventional PKC isozymes (PKC alpha, beta I, beta II, and gamma) contain two CRDs, both of which are candidates for the phorbol ester binding site. In order to elucidate the binding requirements of phorbol esters and to obtain information on the phorbol ester binding site in native PKC gamma, several key chemical characteristics of the first and the second CRDs consisting of ca. 50 amino acids of rat PKC gamma (gamma-CRD1 and gamma-CRD2) were examined. In the presence of Zn2+ and phosphatidylserine (PS), both CRDs gave similar Kd values (65.3 nM for gamma-CRD1, 44.1 nM for gamma-CRD2) in phorbol 12,13-dibutyrate (PDBu) binding assays. In comparison, the binding affinity of PDBu for native rat PKC gamma was found to be 6.8 nM. Zn2+ was shown to play an important role in the folding and PDBu binding of both CRDs. A Zn(2+)-induced conformational change was observed for the first time by CD spectroscopic analysis of the complexed and uncomplexed CRDs. Relative to the pronounced Zn2+ effect, most divalent first row transition metal ions along with Ca2+, Mg2+, and Al3+ were ineffective in folding either CRD. Notably, however, Co2+ exhibited a gamma-CRD1-selective effect, suggesting that metal ions, not unlike extensively used organic probes, might also become effective tools for controlling isozyme selective activation of PKC. Moreover, group Ib (Cu2+ and Ag+) and group IIb element ions other than Zn2+ (Cd2+ and Hg2+) were found to abolish PDBu binding of both CRDs. Importantly, these inhibitory effects of Cu2+, Ag+, and Cd2+, and Hg2+ were also observed with native PKC gamma. These results indicate that recent reports on the modulation of conventional PKC by heavy metal ions could be explained by their coordination to the CRDs. While the similar affinities of gamma-CRD1 and gamma-CRD2 for PDBu suggest that either site qualifies as the PDBu binding site, new molecular probes of these CRD3 have now been identified that provide information on the preferred site. These novel ligands (5a and 5b) were synthesized by aza-Claisen rearrangement of (-)-N13-desmethyl-N13-allylindolactam-G (4). These compounds did not significantly affect the specific PDBu binding of gamma-CRD1 but did inhibit that of gamma-CRD2 with similar potency to (-)-indolactam-V. Moreover, these new probes did not significantly inhibit the PDBu binding of native PKC gamma. (-)-Indolactam-V itself bound almost equally to gamma-CRD1, gamma-CRD2, and native PKC gamma. These results suggest that the major PDBu binding site in native PKC gamma is the first CRD, not the second CRD, unlike the novel PKCs.

Abstract
The transposition patterns of the Ds-GUS transposon T-DNA in 23 independent single-copy lines have been characterized and the map positions of 10 of them on three of the five Arabidopsis chromosomes are reported. Using overexpressed Activator (Ac) elements as a transposase source, it was found that the primary determinant of transposition frequency is the insertion site of the Ac-T-DNA. Neither the structure of the transposon T-DNA nor, in most cases, its insertion site have a significant effect on transposition frequency. Both the frequency and timing of transposition are influenced by the parent through which the transposon and transposase T-DNAs are transmitted. Overall, nearly 75% of plants in which excision has occurred bear a reinserted element and very short-range transpositions predominate, underlining the advantage of using mapped transposons for insertional mutagenesis.

Abstract
A realistic model experiment on hemodynamics was performed to study correlations between wall shear stresses measured in a cast model of the aortic bifurcation and intimal thickness at each corresponding site of the native blood vessel from which the cast had been made. An elastic model of a 54 year old human aortic bifurcation was made of a polyurethane elastomer using a dipping method, and was perfused with Newtonian or non-Newtonian fluid under physiologic pulsatile flow condition. Local flow velocities were measured with an optical-fibered, 3-dimensional laser Doppler anemometer (3D-LDA) to determine wall shear stresses. Distribution of intimal thickness was determined using histological specimens of the native blood vessel. The results obtained are: 1) Non-Newtonian fluid rheology increased wall shear stresses; 2) Positive correlations were observed between intimal thickness and the maximum instantaneous wall shear stress, and 3) However, if we take only the data from the circumference at the level of the flow divider tip, there were negative correlations between them.
