Abstract
Study question
Can providing quality-assured fertility-related information via a smartphone application improve fertility- and treatment-related literacy among smartphone application users?
Summary answer
Provision of quality-assured fertility-related information via a smartphone application contributed to enhancing fertility- and treatment-related literacy among the smartphone application users.
What is known already
For infertility patients, the interpretation of examination results may be overly complicated and complex, and patients may have difficulty in making sense of their own fertility problems. Accessing and learning about fertility-related information using the Internet via smartphone is reasonable; however, the information does not always reflect evidence-based recommendations and low-quality information may lead to adverse effects on users; thus, innovative methods to provide both accessible and high-quality information are desired.
Study design, size, duration
We performed a randomized control-group pretest posttest study and 4,137 smartphone application users were invited to participate between June 18 and 25, 2020. Participants’ fertility treatment-related literacy were assessed with a pretest that comprised of 28 questions and participants were allocated with stratified randomization to either intervention or control group. The intervention comprised a one-week smartphone application-based provision of information on fertility- and treatment-related information and the control group received general information about women’s healthcare.
Participants/materials, setting, methods
The 3,765 participants (91.0 %) who responded were randomly allocated into either the intervention group (N = 1883) or the control group (N = 1882). Characteristics of participants appeared similar between the groups reflecting that the randomization was successful in producing a balance in baseline characteristics. Effectiveness of intervention was assessed using pretest-posttest analysis. Ethical approval was obtained from the Institutional Review Board of the National Center for Child Health and Development of Japan (approval number: 2019-184).
Main results and the role of chance
The posttest was completed by 659 participants (17.5%), and finally 207 participants in the intervention group and 222 participants in the control group were available for pretest-posttest analysis. Demographic characteristics of these participants appeared similar between the groups. In comparing the demographic characteristics of participants who did and did not complete the posttest, there were significant differences between the two groups in age, overall test score, proportion living with a partner, and action for pregnancy. For the posttest, the overall mean test scores were significantly higher in the intervention group compared to the control group (P = 0.0082). Interestingly, we also observed that posttest scores were significantly improved compared to pretest scores in both the intervention group and control group (P < 0.001). When examining by specific test question, the proportion answering correctly appeared to generally increase at posttest compared to pretest for intervention (P < 0.001) and control (P < 0.001) groups. There was over 10% improvement in 7 questions, and particularly, over 20% improvement for a question about clinical significance of anti-Müllerian hormone. Furthermore, directly comparing the difference in posttest versus pretest scores between the two groups showed, on average, greater improvements in the intervention group than the control group (P < 0.001).
Limitations, reasons for caution
As the intervention was educational material, it was not possible to blind participants to intervention group assignment. We were not able to monitor the participants when completing the tests; thus, whether they accessed other resources could not be addressed.
Wider implications of the findings
Providing information through a smartphone application can be considered acceptable since retrieving information through a smartphone application is in line with the current modern day lifestyle. A smartphone application may offer alternatives such as chatbots and movie-based learning, and they have the potential to increase the effectiveness.

Abstract
BACKGROUND AND PURPOSE Obtaining information on invisible vasculature distal to the occlusion site helps to deploy a stent retriever safely during mechanical thrombectomy for large-vessel occlusion. It is essential to reduce the amount of contrast used for detecting the vessels distal to the occlusion site because acute ischemic stroke patients tend to have chronic kidney disease and patients with severe chronic kidney disease are at an increased risk of contrast-associated acute kidney injury. We assessed whether vessels distal to the occlusion site during acute ischemic stroke with large-vessel occlusion could be visualized on angiographic images using flat panel detector CT acquired following intra-arterial diluted contrast injection, compared with MRA findings. MATERIALS AND METHODS Between May 2019 and January 2020, we enrolled 28 consecutive patients with large-vessel occlusions of the anterior circulation eligible for mechanical thrombectomy following MR imaging. The patients underwent CBV imaging using flat panel detector CT with an intra-arterial diluted contrast injection instead of intravenous injection. Flat panel detector CT angiographic images reconstructed from the same dataset were evaluated for image quality, collateral status of the MCA territory, and visualization of the vessels distal to the occlusion site. These findings were compared with MRA findings. RESULTS Twenty-two patients were retrospectively examined. Flat panel detector CT angiographic image quality in 20 patients (91%) was excellent or good. The distal portion of the occluded vessel segment was visualized in 14 patients (70%), while the proximal portion of the segment adjacent to the occluded vessel in 3 (15%) was visualized. No visualization was observed in only 1 patient (5%) with no collateral supply. Flat panel detector CT angiographic images were shown to evaluate vessels distal to the occlusion site more accurately than MRA. CONCLUSIONS In acute ischemic stroke with large-vessel occlusion, flat panel detector CT angiographic images could successfully visualize vessels distal to the occlusion site with a small amount of contrast material.

Abstract
While donor-specific human leukocyte antigen (HLA) antibodies are a frequent cause for chronic antibody-mediated rejection in organ transplantation, this is not the case for antibodies targeting blood group antigens, as ABO-incompatible (ABO-I) organ transplantation has been associated with a favorable graft outcome. Here, we explored the role of CD4 T cell-mediated alloresponses against endothelial HLA-D-related (DR) in the presence of anti-HLA class I or anti-A/B antibodies. CD4 T cells, notably CD45RA-memory CD4 T cells, undergo extensive proliferation in response to endothelial HLA-DR. The CD4 T cell proliferative response was enhanced in the presence of anti-HLA class I, but attenuated in the presence of anti-A/B antibodies. Microarray analysis and molecular profiling demonstrated that the expression of CD274 programmed cell death ligand 1 (PD-L1) increased in response to anti-A/B ligation-mediated extracellular signal-regulated kinase (ERK) inactivation in endothelial cells that were detected even in the presence of interferon-γ stimulation. Anti-PD-1 antibody enhanced CD4 T cell proliferation, and blocked the suppressive effect of the anti-A/B antibodies. Educated CD25+ CD127- regulatory T cells (edu.Tregs ) were more effective at preventing CD4 T cell alloresponses to endothelial cells compared with naive Treg ; anti-A/B antibodies were not involved in the Treg -mediated events. Finally, amplified expression of transcript encoding PD-L1 was observed in biopsy samples from ABO-I renal transplants when compared with those from ABO-identical/compatible transplants. Taken together, our findings identified a possible factor that might prevent graft rejection and thus contribute to a favorable outcome in ABO-I renal transplantation.

Abstract
A feeding study using rats was conducted to evaluate the utility of lablab bean husk and soya bean husk as sources of potential prebiotic fibre. Twenty 5-week-old Sprague Dawley rats were divided into 4 groups and fed one of the following diets for 3 weeks: purified diet (AIN93 G) containing 5% cellulose (CEL), or the same diet in which cellulose was replaced by corn starch (STA), lablab bean husk (LBH), or soya bean husk (SBH). Rats were sacrificed at 8 weeks of age and caecal digesta were collected. Feed intake, body weight, anatomical parameters, and caecal ammonia level did not differ significantly among diets. Rats on LBH and SBH showed higher concentrations of caecal short-chain fatty acid and lactate than those on CEL. Rats on CEL, SBH, and LBH exhibited lower caecal indole and skatole levels. LBH yielded increased caecal abundance of Akkermansia muciniphila and Oscillibacter relatives, as demonstrated by either qPCR, MiSeq, or clone library analysis. SBH favoured the growth of lactobacilli as assessed by both qPCR and MiSeq, and favoured the growth of bifidobacteria as assessed by MiSeq. In comparison with STA, LBH and SBH yielded lower caecal abundance of bacteria related to Dorea massiliensis, as demonstrated by qPCR, MiSeq, and clone library analysis. Both types of bean husk were found to contain oligosaccharides that might selectively stimulate the growth of beneficial bacteria. Based on these results, the two species of bean husk tested are considered potentially functional for promoting the gut health of monogastric animals.

Abstract
Although several sex pheromones of the family Geometridae have been characterized, investigations on Japanese species are limited. In order to obtain more information, screening using known sex pheromones and their analogs was carried out. The (Z,Z,Z)-3,6,9-triunsaturated and (Z,Z)-6,9-diunsaturated hydrocarbons with straight C(19)-C(21) chains were synthesized by the Grignard coupling reaction as a key step starting from linolenic and linoleic acids, respectively. Oxidation of the homoconjugated trienes withm-chloroperoxybenzoic acid yielded a 1∶1∶1 mixture of three monoepoxy derivatives that could be separated by silica gel chromatography. The chemical structure of each positional isomer was confirmed using two-dimensional NMR techniques and MS measurements, which enabled characteristic fragment ions from the isomers to be identified. Field tests using lures incorporating only one of the above six hydrocarbons or nine epoxides were carried out in a forest in Tokyo. Consequently, attraction of male moths of 14 geometrid species in addition to four species in another family, the Noctuidae, was observed. It was concluded that hydrocarbons with a homoconjugated polyene system and the monoepoxy derivatives are important components of sex pheromones produced by Japanese lepidopterous insects, particularly the geometrid moths.

Abstract
We show through first-principles calculations that the electronic properties of Pt4 clusters can be tuned by adsorption on substrates with different electronic valence characters. Pt clusters exhibit a metallic character on γ-Al2O3(111) and insulator properties on CaZrO3(001). The noted difference indicates the role of the electronic valence states of the substrate atoms that directly bond with Pt.

Abstract
Peel adhesive strengths of multi-layered laminates composed of two polypropylene (PP) sheets and an inserted polyethylene (PE) layer (the middle layer) between the PP layers were evaluated. PE-glycidyl methacrylate (GMA) copolymers and a maleic-anhydride grafted PP (MAPP) were compared to the PE homopolymer and the PP homopolymer. The peel adhesive strength of PE-GMA/MAPP laminates was much higher than that of PE homopolymer/PP homopolymer laminates. Meanwhile, the blends composed of the PE-GMA and three types of PE homopolymer (PE-GMA+LDPE, PE-GMA+MDPE, PE-GMA+HDPE) were formulated as the PE middle layer of the multi-layered laminates. The PE blends had the same amount of glycidyl groups, and the deformation capacity was different in each. Namely, the PE blend of LDPE had higher elongation to break than the PE blend of HDPE. The peel adhesive strength of the multi-layered laminates with the middle layer of the LDPE blend was highest among the three types of laminates with the middle layer of the PE blends. Scanning electron microscopy on the fractured surfaces revealed that the large plastic deformation of the LDPE blended middle layer was responsible for the high energy absorption, and resulted in the high peel strength.

Abstract
We compare the electronic properties of Cu(111) and Cu(2)O(111) surfaces in relation to the dissociation of NO using first principles calculations within density functional theory. We note a well-defined three-fold site on both O- and Cu-terminated Cu(2)O surfaces which is verified as the active site for the adsorption and dissociation of NO. The interaction of Cu with O atoms results in the forward shifting of the local density of states and formation of unoccupied states above the Fermi level, compared to the fully occupied d band of pure Cu. These results give valuable insights in the realization of a catalyst without precious metal for the dissociation of NO.

Abstract
NO dissociation on Cu(111) and Cu(2)O(111) surfaces is investigated using spin-polarized density functional theory. This is to verify the possibility of using Cu-based catalyst for NO dissociation which is the rate limiting step for the NO(x) reduction process. The dissociation of molecularly adsorbed NO on the surface is activated for both cases. However, from the reaction path of the NO-Cu(2)O(111) system, the calculated transition state lies below the reference energy which indicates the possibility of dissociation. For the NO-Cu(111) system, the reaction path shows that NO desorption is more likely to occur. The geometric and electronic structure of the Cu(2)O(111) surface indicates that the surface Cu atoms stabilize themselves with reference to the O atom in the subsurface. The interaction results in modification of the electronic structure of the surface Cu atoms of Cu(2)O(111) which greatly affects the adsorption and dissociation of NO. This phenomenon further explains the obtained differences in the dissociation pathways of NO on the surfaces.

Abstract
BACKGROUND Myosin phosphatase activity is regulated by mechanisms involving the phosphorylation of CPI-17 and MYPT1, primarily based on studies with tonic-type vascular smooth muscles. This study examined how these mechanisms contribute to the regulation of contraction of a phasic-type intestinal smooth muscle. METHODS Phosphorylation levels, tension, and Ca(2+) sensitization was detected in rat ileal smooth muscle. Key Results In rat ileal smooth muscle, phosphorylation level of CPI-17 at Thr(38) and MYPT1 at Thr(853) , but not MYPT1 at Thr(696) , were increased with carbachol (1μmolL(-1) ) accompanied with muscle contraction. The PKC inhibitor Go6976 (1μmol L(-1) ) inhibited the carbachol-induced phosphorylation of CPI-17, whereas the Rho-associated kinase (ROCK) inhibitor, Y-27632 (10μmol L(-1) ) inhibited the carbachol-induced phosphorylation of both CPI-17 and MYPT1. Application of Go6976 or Y-27632 alone inhibited the carbachol-induced contraction; however, the combined application of these inhibitors did not inhibit the contraction in an additive manner. In β-escin-permeabilized ileal strip, treatment with antiphosphorylated antibodies for CPI-17 at Thr(38) and MYPT1 at Thr(853) and Thr(696) alone almost completely abolished the Ca(2+) sensitization due to carbachol with GTP. CONCLUSIONS & INFERENCES In conclusion, receptor stimulation increases the Ca(2+) sensitivity of contractile elements through CPI-17 phosphorylation via the PKC/ROCK pathways and MYPT1 phosphorylation via the ROCK pathway, when these mechanisms operate cooperatively and/or synchronously in intestinal smooth muscle.

Abstract
We report a case of a 54-year-old man with T4N0M0 non-small cell lung cancer directly invading the thoracic wall and aortic arch. He underwent neoadjuvant chemotherapy followed by en bloc resection of the tumor, lung, chest wall and aortic arch. Perfusion was maintained through femoral-femoral cardiopulmonary bypass, with permanent bypass to the arch vessels to avoid separate extracorporeal cerebral circulation. Total reconstructions of the chest wall and aortic arch were completed without the need for cardiac arrest. The final pathological diagnosis was squamous cell carcinoma, T4N0M0. The patient was discharged without major complications and has been free of disease for 20 months postoperatively.

Abstract
The nitrogen monoxide (NO) adsorption on platinum tetramer (Pt4) clusters supported on gamma alumina (gamma-Al2O3) with surface index (111) was investigated by using ab-initio calculation based on density functional theory. The Pt4 geometries used in this study are tetrahedron and planar rhombus. The adsorption of Pt4 on gamma-Al2O3 (111) surface in tetrahedron configuration is energetically more favorable as compared to that of the planar rhombus. However, it was found that NO molecule adheres strongly to Pt4 with planar configuration on gamma-Al2O3(111) surface. In addition, the NO adsorption calculation on the isolated Pt4 clusters also shows similar preference to planar configuration. The local density of states (LDOS) reveals that the difference in reactivity comes from the different hybridization strengths between the electronic states of nitrogen atom and those of platinum tetramers. The results are in good agreement with the experiments which show similar tendency for CO and N2O reactivity to gas-phase platinum clusters.

Abstract
2506 Background: Erlotinib demonstrates substantial inter-individual differences in response and the development of skin rash (grade≥2) was correlated with efficacy. Erlotinib interacts with its target EGFR and the efflux transporter ABCB1 and ABCG2. EGFR CA repeat is associated with incidence of skin rash. A 421C>A SNP in ABCG2 and 1236C>T, 2677 G>(T/A), and 3435C>T SNPs in ABCB1 are associated with reduced protein expression. The aim of this study was to evaluate the effects of these variants and pharmacokinetics of erlotinib on toxicity grade in Japanese patients treating single agent erlotinib. Methods: Twenty-two patients with NSCLC received erlotinib orally at 150 mg/day and plasma levels of erlotinib were measured on days 1(D1), 8(D8), and stable phase (>day 14) by high-performance liquid chromatography. DNA from plasma was screened for SNPs in the EGFR, ABCB1, and ABCG2 genes using direct nucleotide sequencing or TaqMan assay. Eligibility criteria included: performance status (PS) < 3, age < 75, stage IIIB-IV, and written informed consent. Results: The mean Cmax (±SD) of D1 and D8 were 1.8 ± 1.0 and 3.1 ± 1.4 μg/ml, respectively. Trough concentration (Cmin) at D1 and steady state were 0.9 and 1.7 μg/ml, respectively. Grade 1–2 skin rash or diarrhea occurred in 95% of patients. One patient (Cmax at D1, 3.0 μg/ml) developed interstitial lung disease after continuous treatment with erlotinib for 3 days. The area under curves and Cmax on D1 were correlated with the severity of skin rash (p=0.05 and 0.01), however, Cmin were not correlated. Patients with homozygous variant and heterozygous for ABCB1 1236C>T, 2677 G>(T/A), and 3435C>T genotype as compared to patients carrying the wild-type were associated with higher Cmin at steady state (2.4 vs 1.2 μg/ml, p=0.01). EGFR CA repeat and AGCG2 421C>A genotype were not associated with any pharmacokinetic parameters. All Patients (n=4) with homozygous variant for ABCB1 1236TT- 2677TT/TA/AA-3435TT developed grade≥2 skin rash or diarrhea. Conclusions: The present study suggests that ABCB1 gene polymorphism is associated with the variable toxicity and pharmacokinetics to erlotinib treatment. No significant financial relationships to disclose.

Abstract
We previously developed a lymphocyte microwell-array system, which effectively detects antigen-specific B-cells by monitoring intracellular Ca(2+) mobilization at the single-cell level with a fluorescent Ca(2+) indicator, fluo-4. However, it is difficult for the system to perform time-lapse monitoring. Here, we developed a novel method, a lymphocyte microwell-array chip system equipped with a charge-coupled device (CCD) time-lapse scanner (MAC-CCD system), for monitoring intracellular Ca(2+) mobilization. The MAC-CCD system is able to monitor intracellular Ca(2+) mobilization of more than 15,000-20,000 individual live B-cells every 10 s. In addition, we adopted a correlation method in a MAC-CCD system, which enabled us to detect B-cells with a frequency of as few as 0.046%. Furthermore, we succeeded in obtaining six influenza nucleoprotein-specific human monoclonal antibodies from the peripheral blood of influenza-vaccinated volunteers. These results demonstrate that the MAC-CCD system with a correlation method could detect very rare antigen-specific B-cells.

Abstract
This study was undertaken to determine whether a single injection of porcine FSH (pFSH) would induce a superovulatory response in cattle. Holstein heifers were given a single injection of pFSH (30 mg, s.c.) dissolved in saline (Group 1, n = 5); 50% polyvinylpyrrolidone (PVP; Group 2, n = 5); or 25% PVP (Group 3, n = 4). Group-4 heifers (n = 5) were given multiple intramuscular injections of pFSH every 12 h for 3 d at decreasing doses, for a total of 30 mg. All animals received a single injection of 750 microg PGF2 alpha 48 h after the initiation of pFSH treatment. Animals exhibiting estrus were artificially inseminated twice throughout estrus. Ova and embryos were recovered nonsurgically. Ovaries were examined by transrectal ultrasonography or by palpation per rectum on Day 7 or 8 of estrus. Plasma concentrations of pFSH, bovine FSH progesterone, estradiol-17 beta and inhibin were determined by specific radioimmunoassays. The number of corpora lutea (CL) and the numbers of total and transferable embryos which were detected and recovered in Groups 2 and 3 were equivalent to the numbers detected and recovered in Group 4. In Group 1, however, only 1 of 5 animals ovulated even a single oocyte. The present study demonstrated that only a single injection of pFSH dissolved in PVP was capable of inducing a superovulatory response by maintaining a high plasma FSH concentration to allow for the recovery of a sufficient number of embryos for transplantation.

Abstract
18179 Background: Because elderly pts may tolerate platinum-based combination chemotherapy poorly, single-agent chemotherapy is selected for the treatment regimen. However, retrospective subgroup analyses have consistently indicated that elderly pts indeed benefit from platinum-based combination chemotherapy as well as their younger counterparts. This phase II study evaluated the efficacy and safety of carboplatin-gemcitabine combination chemotherapy in elderly pts with advanced NSCLC. Methods: Fifty-four pts aged more than 70 years old (median, 77; range, 70–88) with previously untreated advanced NSCLC were enrolled on this trial. Additional criteria included the presence of measurable lesions, an Eastern Cooperative Oncology Group performance status of 0 or 1, and adequate organ function. Pts received carboplatin at an area under the curve of 4 mg/ml/min on the first day and gemcitabine at 1000 mg/m2 on the first and eighth day of consecutive 3 week periods. The primary endpoint was to determine the objective response rate of this platinum-doublet regimen. The RECIST criteria were used to measure response. Results: Enrolled pts included 15/39 with stage IIIB/IV diseases. Fifty-one out of enrolled pts were eligible for efficacy and safety analyses. The median number of treatment cycles was 4 (range, 1–7). Fifteen partial responses (response rate: 29%) were obtained. The median TTP was 118 days. Hematological toxicities of grade 3/4 included leukopenia (46%), neutropenia (72%) and thrombocytopenia (50%). Non-hematological toxicities of grade 3/4 included nausea (6%), appetite loss (7%), fatigue (7%) and infection (9%). Conclusions: The combination carboplatin-gemcitabine at these doses has shown activity with a favorable toxicity profile for fit elderly pts with advanced NSCLC.

Abstract
OBJECTIVES To determine the safety and efficacy of combination chemotherapy with docetaxel (DTX), estramustine phosphate (EMP), and carboplatin (CBDCA) in patients with hormone-refractory prostate cancer (HRPC). METHODS This study included a total of 40 HRPC patients. We evaluated the activity of the following schedule: weekly DTX 30 mg/m(2) iv, daily EMP 10mg/kg po, and CBDCA AUC=6 iv on day 1 of a every 4-wk cycle. Treatment was continued until disease progression or excessive toxicity. RESULTS All patients were assessable for response. A median of six consecutive cycles was administered per patient. Levels of prostate-specific antigen decreased by more than 50% in 95.0% of the patients. Consumption of medication for cancer-induced pain was reduced in 84.6%. Partial response was attained in 66.7% of measurable lesions. Of patients with bone metastasis, 8.3% demonstrated partial response. With a median follow-up of 11.4 mo, the median time to progression was 12.0 mo, and the median overall survival time was 26.6 mo. The predominant toxicities were grade-3 or -4 anemia in 32.5% of the patients, leukopenia in 20.0%, and thrombocytopenia in 17.5%. However, all toxicity was temporary and reversible with dose reduction or temporary cessation of chemotherapeutic agents. There were no therapy-related deaths. CONCLUSIONS Combination chemotherapy with DTX/EMP/CBDCA was found to have significant clinical activity with an acceptable toxicity profile in HRPC patients. More suitable selection of patients may be beneficial in terms of improved overall survival in the future.

Abstract
BACKGROUND The recent rapid increase of mass screening for prostate cancer by measuring PSA in Japan will increase the economic burden to the healthcare system. PSA Rapid Test (PRT) is a simple inexpensive test. The usefulness of PRT as a primary screening test for prostate cancer was evaluated. METHODS When we conducted educational lectures for prostate cancer in our city, screening for prostate cancer using PRT was offered to the male participants. The results of the tests were handed to participants in writing at the end of the lectures. When the results were judged as positive, letters of referral to our institute were enclosed. RESULTS One hundred and fourteen (18.6%) of 614 men were judged as positive by PRT. Of the 114 men with positive PRT, 73 (64%) visited our institution. Finally, 37 men underwent a transrectal prostate biopsy and a diagnosis of prostate cancer was made in 21 men (3.4% of all participants). The total costs for the PSA tests in this study were summed to be approximately $2,300, while they would be approximately $9,200 if all participants had undergone screening using the conventional quantitative method from the outset. CONCLUSION PRT is a low-cost method to detect patients with prostate cancer. We believe the PRT is useful as an initial screening test for detecting prostate cancer and that the combination of the PRT and more precise quantitative testing would be a reasonable way to reduce the cost and achieve high detection rate.

Abstract
PURPOSE Aberrant activation of the Wingless-type (Wnt) pathway plays a significant role in the pathogenesis of several human cancers. Wnt inhibitory factor-1 (Wif-1) was identified as one of the secreted antagonists that can bind Wnt protein. We hypothesize that Wif-1 plays an important role in bladder cancer pathogenesis. EXPERIMENTAL DESIGN To test this hypothesis, epigenetic and genetic pathways involved in the Wif-1 gene modulation and expression of Wnt/beta-catenin-related genes were analyzed in 4 bladder tumor cell lines and 54 bladder tumor and matched normal bladder mucosa. RESULTS Wif-1 mRNA expression was significantly enhanced after 5-aza-2'-deoxycytidine treatment in bladder tumor cell lines. Wif-1 promoter methylation level was significantly higher and Wif-1 mRNA expression was significantly lower in bladder tumor samples than in bladder mucosa samples. In the total bladder tumor and bladder mucosa samples, an inverse correlation was found between promoter methylation and Wif-1 mRNA transcript levels. However, loss-of-heterozygosity at chromosome 12q14.3 close to the Wif-1 gene loci was a rare event (3.7%). Nuclear accumulation of beta-catenin was significantly more frequent in bladder tumor than in bladder mucosa and inversely correlated with Wif-1 expression. In addition, known targets of the canonical Wnt/beta-catenin signaling pathway, such as c-myc and cyclin D1, were up-regulated in bladder tumor compared with bladder mucosa, and this up-regulation was associated with reduced Wif-1 expression at both mRNA and protein levels. Furthermore, transfection of Wif-1 small interfering RNA into bladder tumor cells expressing Wif-1 mRNA transcripts had increased levels of c-myc and cyclin D1 and accelerated cell growth. CONCLUSION This is the first report showing that CpG hypermethylation of the Wif-1 promoter is a frequent event in bladder tumor and may contribute to pathogenesis of bladder cancer through aberrant canonical Wnt/beta-catenin signaling pathway. The present study elucidates novel pathways that are involved in the pathogenesis of bladder cancer.

Abstract
PURPOSE We report the difference in quality of life (QOL) between patients with an orthotopic neobladder and normative values in the age matched Japanese population. MATERIALS AND METHODS Between November 1996 and June 2003, 75 patients underwent orthotopic neobladder construction at our institution, of whom 47 males and 9 females were enrolled in this study. A total of 19 patients were excluded because of death or insufficient followup (less than 6 months). Two types of questionnaire, namely the RAND 36-Item Health Survey, version 2 and the Functional Assessment of Cancer Therapy-Bladder Cancer, were mailed to all 56 patients. The 48 patients (86%) who returned the completed forms were included in our analysis. Postoperative QOL was compared with age matched normative values in the control Japanese population. RESULTS Overall there was no significant difference in any scale between patients with a neobladder and the age matched control Japanese population. The patient bodily pain score in the seventh decade of life and the role-physical score in those older than 70 years were better than age matched normative values in the Japanese population (p < 0.005 and p < 0.05, respectively). Male patients in the seventh decade of life were more likely to have better QOL in the physical functioning, role-physical and role-emotional subscales in addition to the bodily pain subscale compared to age matched control values (p < 0.05, < 0.05, < 0.001 and < 0.001, respectively). Likewise in male patients older than 70 years role-physical scores remained better than age matched normative values in the Japanese population (p < 0.01). Further analysis of bladder cancer related QOL showed that patients followed more than 24 months were more likely to have a lower incontinence score than those followed less than 24 months (p < 0.05). In addition, the continence related QOL change alone did not affect any health related QOL scales, as analyzed by RAND 36-Intem Health Survey. CONCLUSIONS Our study shows that there is no essential difference in health related QOL between patients with a neobladder and the age matched Japanese control population. The current results provide some primary evidence to help in decision making and eliminate potential anxiety about worse QOL after cystectomy.

Abstract
Previously, we reported recessive gene(s) that terminate fetal development on swine chromosome (SSC) 6 between SW855 and SW122. The affected alleles originated from a Göttingen miniature pig used for construction of a Göttingen miniature pig x Meishan resource population. However, it is not known when the gene(s) are activated during fetal development, which is one of the important factors in selecting candidate genes responsible for fetal death. In the present study, a second swine population consisting of 159 progeny was produced by mating pigs carrying the deleterious allele(s). This population allowed us to narrow the genetic region harbouring the affected gene(s) and to demonstrate that the region was confined between RYR1 and SW782 (5.7 cM on the National Institute of Animal Industry (NIAI) map and 100 cR on the INRA/University of Minnesota porcine radiation hybrid panel map). In order to determine when the affected gene(s) are activated and in turn terminate fetal development, embryos produced in the second population were collected at several development stages and genotyped for markers in the region. Genes in the homozygous state affected embryo development between 9 and 11 days post-coitus.

Abstract
A case of orbital emphysema as a sequel of a snowboard related head injury is reported. It is believed that a fracture of the medial orbital wall was caused by the increased intraorbital pressure when the patient hit his forehead on the snowy ground, allowing air to enter the orbit when he blew his nose. Wearing goggles may prevent this type of sports related injury.

Abstract
OBJECTIVES To examine docetaxel (DTX)-based chemotherapy in paclitaxel (PTX)-based chemotherapy-resistant hormone-refractory prostate cancer (HRPC) to investigate the activity and degree of toxicity in a pilot study. We have previously reported on the effectiveness of combination chemotherapy with PTX, estramustine (EMP), and carboplatin against HRPC. Although many patients with HRPC initially responded to this PTX/EMP-based combination chemotherapy, most finally progressed to PTX-resistant status within a mean of less than 1 year. DTX is an inhibitor of microtubule depolymerization like PTX and has demonstrated activity against PTX-resistant metastatic tumors. METHODS The subjects were 15 patients with HRPC who displayed disease progression while receiving PTX/EMP/carboplatin combination chemotherapy. The patients were treated with intravenous DTX 30 mg/m2 weekly, oral EMP 10 mg/kg daily, and intravenous carboplatin (dosed to an area under the curve of 6) on day 1 of every 4-week cycle. Treatment was continued until disease progression or excessive toxicity. RESULTS Each patient received a median of eight consecutive cycles. The prostate-specific antigen level decreased by 50% or more in 33.3% of patients and by 90% or more in 13.3%. The median follow-up was 49.6 weeks, with median time to progression of 25.0 weeks and median overall survival of 54.0 weeks. One patient died of interstitial pneumonitis. One patient developed secondary osteomyelodysplastic syndrome. The major severe toxicities were grade 3 or 4 anemia in 66.7% of patients, leukopenia in 26.7%, and thrombocytopenia in 40.0%. CONCLUSIONS The results of our study have shown that DTX is comparatively active for heavily pretreated patients with PTX-resistant HRPC. However, given the significant toxicities and small subject population, well-designed Phase I-II trials of the improved regimen are warranted.

Abstract
BACKGROUND The action of transforming growth factor beta (TGF-beta) is mediated through type 1 (TbetaRI) and type 2 (TbetaRII) receptors. Prostate cancer cells are often resistant to TGF-beta signaling due to loss of TbetaRII expression. The authors of the current study hypothesized that CpG methylation of the TbetaRII promoter at the Sp1 binding site -140 mediates this loss of TbetaRII expression in prostate cancer. METHODS Sixty-seven prostate cancer (PC) samples, 8 benign prostatic hyperplasia (BPH) samples, and 4 prostate cancer cell lines (DUPro, LNCaP, ND-1 and PC-3) were analyzed for 1) TbetaRII mRNA expression by semiquantitative RT-PCR, 2) TbetaRII protein expression by immunohistochemistry, and 3) TGFbetaRII promoter methylation at CpG site -140 by methylation specific PCR and bisulfite DNA sequencing. Prostate cancer cell lines were treated with the demethylating agent 5aza2'deoxycytidine to determine if TbetaRII gene expression could be increased by blocking promoter methylation. RESULTS mRNA and protein expression of TbetaRII was lower in the PC samples than in the BPH samples. CpG methylation at site -140 was higher in PC than in BPH (P < 0.01). Promoter methylation was inversely correlated with TbetaRII mRNA expression in the PC and BPH samples (P < 0.0001). PC3, ND1, and DUPro TbetaRII mRNA expression increased following treatment of cells with 5-aza-2'-deoxycytidine. CONCLUSION CpG methylation of the TbetaRII promoter at CPG site -140 leads to functional loss of the TbetaRII gene in prostate cancer. Treatment with 5-aza-2' deoxycytidine can restore gene expression. The current study results report the first association between prostate cancer and loss of the TGF- beta signaling pathway by TbetaRII DNA promoter methylation.
