Abstract
Survival rates of patients with Philadelphia chromosome-positive ALL (Ph+ALL) have improved considerably with the introduction of tyrosine kinase inhibitors (TKI); however, hematopoietic stem cell transplantation (HSCT) continues to play an important role. Reduced-intensity conditioning (RIC) regimens have been widely applied particularly for older patients, but their validity for children and adolescents with Ph+ALL has not been investigated. In this study, data from patients receiving HSCT for de novo Ph+ALL in first or second remission at ages younger than 25 years and with a history of pre-HSCT TKI therapy were retrospectively collected through the nationwide registry in Japan. In 265 patients who received myeloablative conditioning (MAC) and 33 patients receiving RIC, 5-year leukemia-free survival (LFS) rates were 67.3% and 79.8%, respectively (p = 0.142). Multivariate analysis of LFS, focusing on patients with good performance status, identified RIC as a significant prognostic factor for LFS (hazard ratio 0.32, p = 0.032), as well as older age, higher leukocyte count at diagnosis, and disease with additional chromosomal abnormalities. These trends were similar when we focused on patients who received prophylactic post-HSCT TKI treatment, as 5-year LFS was 81.0% for MAC and 84.4% for RIC (p = 0.748). In summary, HSCT with RIC regimen showed at least comparable LFS to HSCT with MAC regimen, and RIC was an independent favorable prognostic factor on multivariate analysis adjusting potential prognostic factors. While patient numbers were limited, our data suggest that RIC may be safely applied in this group, particularly combined with prophylactic post-HSCT TKI maintenance therapy.

Abstract
Purpose: Although fertility preservation for pediatric cancer patients is becoming more widespread in Japan, some facilities do not provide sufficient information regarding fertility. This study aimed to elucidate the problems pertaining to the lack of information about fertility among patients. Methods: Based on a 2020 survey, seminars addressing fertility preservation were held from the Designated Pediatric Cancer Care Hospitals in each of the seven blocks in Japan to their partner hospital (pediatric cancer hospitals). The seminar consisted of lectures and group discussions, and a questionnaire was also administered after each seminar. Results: In the group discussions, a lack of explanations to patients and explanatory materials for children were cited as issues by many facilities. The survey results revealed a lack of material explaining fertility preservation and a lack of knowledge among health care providers. There were also many requests to use the patient explanation videos presented at the seminar. Conclusion: The results indicate that further education for health care providers by seminar and other sources and enhancement of explanatory materials are important for fertility preservation in pediatric cancer hospitals in Japan.

Abstract
HLA 1-locus-mismatched unrelated donors (1MMUD) have been used in allogeneic hematopoietic stem cell transplantation (allo-HCT) for patients who lack an HLA-matched donor. We retrospectively analyzed 3313 patients with acute leukemia or myelodysplastic syndrome who underwent bone marrow transplantation from an HLA allele-matched unrelated donor (MUD) or 1MMUD between 2009 and 2014. We compared the outcomes of MUD (n=2089) and 1MMUD with antithymocyte globulin (ATG) (1MM-ATG(+); n=109) with those of 1MMUD without ATG (1MM-ATG(-); n=1115). The median total dose of ATG (thymoglobulin) was 2.5 mg/kg (range 1.0-11.0 mg/kg) in the 1MM-ATG(+) group. The rates of grade III-IV acute GvHD, non-relapse mortality (NRM) and overall mortality were significantly lower in the MUD group than in the 1MM-ATG(-) group (hazard ratio (HR) 0.77, P=0.016; HR 0.74; P<0.001; and HR 0.87, P=0.020, respectively). Likewise, the rates of grade III-IV acute GVHD, NRM and overall mortality were significantly lower in the 1MM-ATG(+) group than in the 1MM-ATG(-) group (HR 0.42, P=0.035; HR 0.35, P<0.001; and HR 0.71, P=0.042, respectively). The outcome of allo-HCT from 1MM-ATG(-) was inferior to that of allo-HCT from MUD even in the recent cohort. However, the negative impact of 1MMUD disappeared with the use of low-dose ATG without increasing the risk of relapse.

Abstract
Hepatitis B virus (HBV) and hepatitis delta virus (HDV) co-infections progress rapidly and lead to cirrhosis. In Japan, the prevalence of HBV and HDV co-infected patients is low. Therefore, there are few reports of patients with HBV and HDV co-infection having undergone liver transplantation. Herein, we report a rare case of recurrence of HBV and HDV in a 41-year-old man who underwent living donor liver transplantation 4 years prior.

Abstract
INTRODUCTION Recently, several studies have shown that specific single nucleotide polymorphisms (SNPs) affect liver fibrosis progression in patients with hepatitis C virus (HCV) infection. In this study, we examined the impact of donor and recipient SNPs on the progression of fibrosis after liver transplantation for HCV infection. METHODS This cohort study enrolled 43 patients with HCV infection who underwent liver transplantation at our hospital. We evaluated 5 genotypes (rs4374383, rs2629751, rs9380516, rs8099917, and rs738409) that have been reported to be significant predictors of fibrosis in HCV infection using a Taqman assay. RESULTS Liver fibrosis (stage ≥ F1, New Inuyama classification) was detected at 1 year after liver transplantation in 30 cases (70%). The rs2629751 non-AA-genotype was found to be significantly associated with fibrosis progression at 1 year after liver transplantation (AA:GG or GA = 46%:88%, P < .05). The primary outcome was stage ≥F2 (portoportal septa) or liver-related mortality in 22 patients. The time to stage ≥F2 fibrosis or liver-related mortality was significantly different only in terms of the donor rs2629751 genotype (AA:GG or GA = 5.5 ± 0.6 years:3.6 ± 0.7 years, P = .025). CONCLUSIONS The rs2629751 genotype may be an important predictor of posttransplant outcome in HCV-infected patients. This result might be useful in donor selection for liver transplantation in HCV-infected patients and may guide therapeutic decisions regarding early antiviral treatment.

Abstract
INTRODUCTION A high incidence of thyroid dysfunction is reported in patients with HIV or HCV mono-infection. We have conducted a periodic medical examination including the thyroid function for haemophilic patients with HIV/HCV co-infection due to contaminated blood products. METHODS We examined the thyroid function (as assessed by the FT3, FT4 and TSH levels) in 45 haemophilic patients, including thyroglobulin and auto-antibody, antithyroglobulin antibody, antithyroid peroxidase antibody and anti-TSH receptor antibody in 28 patients. RESULTS All the patients were males (median age: 42 years; range: 29-66). The median values of thyroid function were FT3 3.36 pg mL(-1) , FT4 1.125 ng mL(-1) and TSH 1.65 μIU mL(-1) . Five patients (11.1%) had high TSH levels. In 28 patients in whom the presence of auto-antibodies was examined, the median age was 47 years of age. The median value of thyroglobulin was 16 ng mL(-1) and two patients showed high levels of thyroglobulin. The presence of anti-TSH receptor antibody of all the patients was negative, but one patient (3.5%) was positive of antithyroid peroxidase antibody and antithyroglobulin antibody. CONCLUSIONS Since 0.68-3.6% of the general healthy population is reported to show hypothyroidism, our data showed that the proportion of hypothyroidism in haemophilic patients with HIV/HCV co-infection was more frequent than that of the normal population.

Abstract
BACKGROUND We have previously reported a hybrid procedure that uses a combination of laparoscopic mobilization of the liver and subsequent hepatectomy under direct vision in living donor liver transplantation (LDLT). We present the details of this hybrid procedure and the outcomes of the procedure. METHODS Between January 1997 and August 2014, 204 LDLTs were performed at Nagasaki University Hospital. Among them, 67 recent donors underwent hybrid donor hepatectomy. Forty-one donors underwent left hemihepatectomy, 25 underwent right hemihepatectomy, and 1 underwent posterior sectionectomy. First, an 8-cm subxiphoid midline incision was made; laparoscopic mobilization of the liver was then achieved with a hand-assist through the midline incision under the pneumoperitoneum. Thereafter, the incision was extended up to 12 cm for the right lobe and posterior sector graft and 10 cm left lobe graft procurement. Under direct vision, parenchymal transection was performed by means of the liver-hanging maneuver. The hybrid procedure for LDLT recipients was indicated only for selected cases with atrophic liver cirrhosis without a history of upper abdominal surgery, significant retroperitoneal collateral vessels, or hypertrophic change of the liver (n = 29). For total hepatectomy and splenectomy, the midline incision was sufficiently extended. RESULTS All of the hybrid donor hepatectomies were completed without an extra subcostal incision. No significant differences were observed in the blood loss or length of the operation compared with conventional open procedures. All of the donors have returned to their preoperative activity level, with fewer wound-related complaints compared with those treated with the use of the conventional open procedure. In recipients treated with the hybrid procedure, no clinically relevant drawbacks were observed compared with the recipients treated with a regular Mercedes-Benz-type incision. CONCLUSIONS Our hybrid procedure was safely conducted with the same quality as the conventional open procedure in both LDLT donors and recipients.

Abstract
Allogeneic hematopoietic SCT (allo-HSCT) is a curative treatment for aggressive adult T-cell leukemia/lymphoma (ATLL). Considering the dismal prognosis associated with conventional chemotherapies, early application of allo-HSCT might be beneficial for patients with ATLL. However, no previous study has addressed the optimal timing of allo-HSCT from related donors. Hence, to evaluate the impact of timing of allo-HSCT for patients with ATLL, we retrospectively analyzed data from patients with ATLL who received an allo-HSCT from a related donor. The median age was 52 years. Patients were grouped according to the interval from diagnosis to allo-HSCT: early transplant group, <100 days, n=72; late transplant group, ⩾100 days, n=428. The corresponding constituents of disease status were not statistically different between the two groups (P=0.11). The probability of OS in the early transplant group was significantly higher than that in the late transplant group (4-year OS, 49.3% vs 31.2%). Multivariate analysis revealed that late allo-HSCT was an unfavorable prognostic factor for OS (hazard ratio, 1.46; 95% confidence interval (CI), 1.01-2.11; P=0.04). Despite the limitations of a retrospective study, it might be acceptable to consider early application of allo-HSCT for ATLL.

Abstract
BACKGROUND The aim of this study was to evaluate the influence of previous local treatment on the E-cadherin (E-cad) expression in cases of hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT) within the Milan criteria. METHODS Seventy-four of 204 patients with HCC underwent LDLT between 1997 and 2014. Previous local treatment for HCC was performed for 121 lesions in 47 patients (47/74, 63.5%). Histological and immunohistochemical E-cad expression analyses were conducted on the basis of the whole-liver histological examination technique. RESULTS The interval to LDLT after the initial and last treatments was 24 months (2-206) and 10.5 months (1-58), respectively. Preoperative imaging showed necrosis in 92 (92/121, 76.0%) lesions caused by the effects of local treatment, whereas the histological examinations revealed viable HCC cells in 22 (22/92, 23.9%) lesions, demonstrating well or moderate differentiation without vascular invasion. Immunohistochemically, the expression of E-cad was maintained in 17 viable (17/22, 77.3%) lesions. There were no signs of malignant transformation or sarcomatous changes in the HCCs treated with previous therapy. The recipients who maintained an E-cad expression in the lesion with local treatment showed no recurrence or distant metastasis after LDLT. CONCLUSIONS HCC cells remained in approximately 20% of the evaluated lesions, even those exhibiting necrosis on imaging of the explanted cirrhotic liver. However, the expression of E-cad was maintained in most of these lesions. Furthermore, there were no significant differences in the rate of recurrence after LDLT between the patients who did and those did not receive previous local treatment for HCC.

Abstract
In unrelated hematopoietic SCT (HSCT), HLA allele mismatch has been shown to have a significant role. To clarify the importance of HLA allele mismatch in the GVH direction in related HSCT, we retrospectively evaluated 2377 patients who received stem cells from an HLA serologically matched related donor in the GVH direction using the database of the Japan Society for Hematopoietic Cell Transplantation. The cumulative incidences of grade II-IV and grade III-IV acute GVHD in patients with an HLA allele-mismatched donor (n=133, 5.6%) were significantly higher than those in patients with an HLA allele-matched donor. Multivariate analyses showed that the presence of HLA allele mismatch was associated with increased risks of grade II-IV and grade III-IV acute GVHD. In particular, HLA-B mismatch and multiple allele mismatches were associated with an increased risk of acute GVHD. The presence of HLA allele mismatch was associated with an inferior OS owing to an increased risk of non-relapse mortality (NRM). In conclusion, the presence of HLA allele mismatch in the GVH direction in related HSCT was associated with increased risks of GVHD and NRM, which led to an inferior OS. HLA allele typing is recommended in related HSCT.

Abstract
BACKGROUND We aimed to clarify the impact of the donor source of allogeneic stem cell transplantation (allo-SCT) on Philadelphia chromosome-negative acute lymphoblastic leukemia [Ph(-) ALL] with focus on cord blood (CB). PATIENTS AND METHODS We retrospectively analyzed data of 1726 patients who underwent myeloablative allo-SCT for adult Ph(-) ALL. The sources of the allo-SCT were related donors (RD; N = 684), unrelated donors (URD; N = 809), and CB (N = 233). RESULTS Overall survival (OS) in patients after CB allo-SCT in first complete remission (CR1) was comparable with that after RD or URD allo-SCT (RD: 65%, URD: 64% and CB: 57% at 4 years, P = 0.11). CB was not a significant risk factor for relapse or non-relapse mortality as well as for OS in multivariate analyses. Similarly, the donor source was not a significant risk factor for OS in subsequent CR or non-CR (RD: 47%, URD: 39% and CB: 48% in subsequent CR, P = 0.33; RD: 15%, URD: 21% and CB: 18% in non-CR, P = 0.20 at 4 years). CONCLUSION Allo-SCT using CB led to OS similar to those of RD or URD in any disease status. To avoid missing the appropriate timing, CB is a favorable alternative source for adult Ph(-) ALL patients without a suitable RD or URD.

Abstract
BACKGROUND Outcomes of liver resection for hepatocellular carcinoma (HCC) have improved owing to better surgical techniques and patient selection. Portal hypertension may influence outcome but the preoperative definition and role of portal hypertension are far from clear. The aim of this study was to elucidate the influence of portal venous pressure (PVP) measured directly during surgery on outcomes of liver resection in patients with HCC. METHODS Patients who had resection of HCC between 1997 and 2009, and who underwent direct measurement of PVP immediately after laparotomy were enrolled. These patients were divided into groups with high (at least 20 cmH(2)O) and low (less than 20 cmH(2)O) PVP. The influence of PVP on overall and recurrence-free survival was analysed and prognostic factors were identified. RESULTS A total of 177 patients were enrolled, 129 in the low-PVP group and 48 in the high-PVP group. The 5-year overall survival rate (63·7 versus 31 per cent; P < 0·001) and recurrence-free survival rate (52·5 versus 12 per cent; P < 0·001) were significantly higher in patients with low PVP. In multivariable analysis, two or more tumours, tumour diameter at least 5 cm, high PVP, grade B liver damage and Hepatic Activity Index (HAI) grade 7 or more were significant predictors of poorer survival after liver resection. Two or more tumours, tumour diameter at least 5 cm and HAI grade 7 or more were significant predictors of poorer recurrence-free survival. CONCLUSION High PVP was associated with poor long-term outcome after liver resection for HCC.

Abstract
BACKGROUND Recently, applications of less invasive liver surgery in living donor hepatectomy (LDH) have been reported. The objective of this study was to evaluate the safety and efficacy of a hybrid method with a midline incision for LDH. METHODS Hemihepatectomy using the hybrid method was performed in the fifteen most recent among 150 living donors who underwent surgery between 1997 and August 2011. Six donors underwent right hemihepatectomy and 9 underwent left hemihepatectomy. An 8-cm subxiphoid midline incision was created for hand assistance during liver mobilization and graft extraction. After sufficient mobilization of the liver, the hand-assist/extraction incision was extended to 12 cm for the right hemihepatectomy and 10 cm for a left hemihepatectomy. Encircling the hepatic veins and hilar dissection were performed under direct vision. Parenchymal transection was performed with the liver hanging maneuver. Bile duct division was performed after visualizing the planned transection point by encircling the bile duct using a radiopaque marker filament under real-time C-arm cholangiography. RESULTS All procedures were completed without any extra subcostal incision. All grafts were safely extracted through the 10-12-cm upper midline incision without mechanical injury. No donors required an allogeneic transfusion; all of them have returned to their preoperative activity levels. CONCLUSION LDH by the hybrid method with a short upper midline incision is a safe procedure.

Abstract
Cellulose acetate (CA) beads are often used for leucocyte apheresis therapy against inflammatory bowel disease. In order to clarify the mechanism of the anti-inflammatory effects of CA, global analysis of the molecules generated in blood by the interaction with CA beads was performed in this study. An activated medium was collected from whole blood that had been preincubated with CA beads, and the effects of the CA-activated medium on leucocyte function were investigated. Fresh blood was stimulated with lipopolysaccharide (LPS) or interferon (IFN)-β in the presence of the activated medium, and levels of chemokines and cytokines, including CXCL10 (IFN-inducible protein-10), and phosphorylated STAT1 (signal transducer and activator of transcription 1), which is known to be essential for CXCL10 production in leucocytes, were measured. IFN-β- or LPS-induced CXCL10 production, expression of CXCL10 mRNA and phosphorylation of STAT1 were significantly reduced in the presence of the medium pretreated with CA beads compared with the control without the CA bead treatment. The factors inhibiting CXCL10 production were identified as the C3 and C4 fragments by mass spectrometry. The monomeric C3bi and C4b proteins were abundant in the medium pretreated with CA beads. Furthermore, purified C3bi and C4b were found to inhibit IFN-β-induced CXCL10 production and STAT1 phosphorylation. Thus, STAT1-mediated CXCL10 production induced by stimulation with LPS or IFN was potently inhibited by monomeric C3bi and C4b generated by the interaction of blood with CA beads. These mechanisms mediated by monomeric C3bi and C4b may be involved in the anti-inflammatory effects of CA.

Abstract
Acute myeloid leukemia (AML) with t(6;9)(p23;q34) is well known to have a poor prognosis treated with chemotherapy and autotransplantation. The presence of this karyotype is an indicator for allogeneic hematopoietic stem cell transplantation (HSCT); however, the impact of t(6;9)(p23;q34) on the HSCT outcome remains unclear. We conducted a matched-pair analysis of de novo AML patients with and without t(6;9)(p23;q34) using data obtained from the Japanese HSCT data registry. A total of 57 patients with t(6;9)(p23;q34) received transplants between 1996 and 2007, and 171 of 2056 normal karyotype patients matched for age, disease status at HSCT and graft source were selected. The overall survival, disease-free survival, cumulative incidence of relapse and the non-relapse mortality in t(6;9)(p23;q34) patients were comparable to those for normal karyotype patients. A univariate analysis showed that t(6;9)(p23;q34) had no significant impact on the overall survival. These findings suggest that allogeneic HSCT may overcome the unfavorable impact of t(6;9)(p23;q34) as an independent prognostic factor.

Abstract
Chronic GVHD (cGVHD) of the liver is an important cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (allo-SCT). It is characterized by the destruction of bile duct epithelium followed by progressive cholestasis, which resembles primary biliary cirrhosis (PBC) clinically and histologically. Bezafibrate (BF) is a widely used agent for hyperlipidemia that is also effective in ursodeoxycholic acid (UDCA)-resistant PBC patients. The putative mechanism in cholestasis is that BF upregulates the expression of phosphatidylcholine flippase on bile canaliculi, facilitates phospholipid output into bile and relieves bile duct damage caused by hydrophobic bile salts. Therefore, the effects of BF in patients with cGVHD of the liver were investigated. Of 87 patients with cGVHD who survived more than 100 days after SCT, 8 were given BF to treat liver cGVHD because of a poor therapeutic response to UDCA and immunosuppressants. The serum alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (gamma-GTP) levels decreased significantly within 1 month after initiation of BF therapy compared with those before BF therapy in all patients (ALP, 964.9.0+/-306.9 to 597.8+/-102.5 IU/l, P=0.012; gamma-GTP, 528.8+/-299.0 to 269.0+/-119.9 IU/l, P=0.012). BF was effective in patients with liver cGVHD, including UDCA-resistant patients. BF could be a novel therapeutic option for liver cGVHD that helps to preserve normal immunity with the antileukemic effect of cGVHD.

Abstract
O(6)-Methylguanine produced in DNA induces mutation due to its ambiguous base-pairing properties during DNA replication. To suppress such an outcome, organisms possess a mechanism to eliminate cells carrying O(6)-methylguanine by inducing apoptosis that requires the function of mismatch repair proteins. To identify other factors involved in this apoptotic process, we performed retrovirus-mediated gene-trap mutagenesis and isolated a mutant that acquired resistance to a simple alkylating agent, N-methyl-N-nitrosourea (MNU). However, it was still sensitive to methyl methanesulfonate, 1-(4-amino-2-methyl-5-pyrimidinyl)methyl-3-(2-chloroethyl)-3-nitrosourea, etoposide and ultraviolet irradiation. Moreover, the mutant exhibited an increased mutant frequency after exposure to MNU. The gene responsible was identified and designated Mapo1 (O(6)-methylguanine-induced apoptosis 1). When the expression of the gene was inhibited by small interfering RNA, MNU-induced apoptosis was significantly suppressed. In the Mapo1-defective mutant cells treated with MNU, the mitochondrial membrane depolarization and caspase-3 activation were severely suppressed, although phosphorylation of p53, CHK1 and histone H2AX was observed. The orthologs of the Mapo1 gene are present in various organisms from nematode to humans. Both mouse and human MAPO1 proteins expressed in cells localize in the cytoplasm. We therefore propose that MAPO1 may play a role in the signal-transduction pathway of apoptosis induced by O(6)-methylguanine-mispaired lesions.

Abstract
Reuse of wastewater is regarded as one important way to deal with the world's shortage of potable water. The authors focused on a disinfection system using micro-bubbles and evaluated its capability for wastewater reuse. This paper reports experimental results from examination of the basic characteristics of micro-bubbles and disinfection of secondary effluent by air or ozone micro-bubbles. The results suggest that when micro-bubbles are applied in an ozonation system it is possible to reduce the reactor size, the amount of ozone decomposition equipment needed and the ozone dose rate.

Abstract
Efficacy of reduced-intensity stem-cell transplantation (RIST) for acute lymphoblastic leukemia (ALL) was investigated in 33 patients (median age, 55 years). RIST sources comprised 20 HLA-identical related donors, five HLA-mismatched related, and eight unrelated donors. Six patients had undergone previous transplantation. Disease status at RIST was first remission (n=13), second remission (n=6), and induction failure or relapse (n=14). All patients tolerated preparatory regimens and achieved neutrophil engraftment (median, day 12.5). Acute and chronic graft-versus-host disease (GVHD) developed in 45 and 64%, respectively. Six patients received donor lymphocyte infusion (DLI), for prophylaxis (n=1) or treatment of recurrent ALL (n=5). Nine patients died of transplant-related mortality, with six deaths due to GVHD. The median follow-up of surviving patients was 11.6 months (range, 3.5-37.3 months). The 1-year relapse-free and overall survival rates were 29.8 and 39.6%, respectively. Of the 14 patients transplanted in relapse, five remained relapse free for longer than 6 months. Cumulative rates of progression and progression-free mortality at 3 years were 50.9 and 30.4%, respectively. These findings suggest the presence of a graft-versus-leukemia effect for ALL. RIST for ALL is worth considering for further evaluation.

Abstract
This study examined the importance of mycosporine-glycine (Myc-Gly) as a functional antioxidant in the thermal-stress susceptibility of two scleractinian corals, Platygyra ryukyuensis and Stylophora pistillata. Photochemical efficiency of PSII (F(v)/F(m)), activity of antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT), and composition and abundance of mycosporine-like amino acids (MAAs) in the coral tissue and in symbiotic zooxanthellae were analyzed during 12-h exposure to high temperature (33 degrees C). After 6- and 12-h exposures at 33 degrees C, S. pistillata showed a significantly more pronounced decline in F(v)/F(m) compared to P. ryukyuensis. A 6-h exposure at 33 degrees C induced a significant increase in the activities of SOD and CAT in both host and zooxanthellae components of S. pistillata while in P. ryukyuensis a significant increase was observed only in the CAT activity of zooxanthellae. After 12-h exposure, the SOD activity of P. ryukyuensis was unaffected in the coral tissue but slightly increased in zooxanthellae, whereas the CAT activity in the coral tissue showed a 2.5-fold increase. The total activity of antioxidant enzymes was significantly higher in S. pistillata than in P. ryukyuensis, suggesting that P. ryukyuensis is less sensitive to oxidative stress than S. pistillata. This differential susceptibility of the corals is consistent with a 20-fold higher initial concentration of Myc-Gly in P. ryukyuensis compared to S. pistillata. In the coral tissue and zooxanthellae of both species investigated, the first 6 h of exposure to thermal stress induced a pronounced reduction in the abundance of Myc-Gly but not in other MAAs. When exposure was prolonged to 12 h, the Myc-Gly pool continued to decrease in P. ryukyuensis and was completely depleted in S. pistillata. The delay in the onset of oxidative stress in P. ryukyuensis and the dramatic increase in the activities of the antioxidant enzymes in S. pistillata, which contains low concentrations of Myc-Gly suggest that Myc-Gly provides rapid protection against oxidative stress before the antioxidant enzymes are induced. These findings strongly suggest that Myc-Gly is functioning as a biological antioxidant in the coral tissue and zooxanthellae and demonstrate its importance in the survival of reef-building corals under thermal stress.

Abstract
We herein present a case of attenuated familial adenomatous polyposis (AFAP) with advanced rectal cancer in a 16-year-old boy. His mother and younger brother both had subcutaneous soft tissue tumors in the back and sparse-type colorectal polyposis. His mother also had dental anomalies and gastric fundic gland polyposis. The patient was admitted to our hospital for investigation of bloody stools. Barium enema and colonofiberscopy revealed advanced rectal cancer and sparse (<50) colorectal polyps. He also had dental anomalies, a subcutaneous soft tissue tumor in the back, and gastric fundic gland polyposis as extracolonic manifestations. A total proctocolectomy and ileoanal anastomosis were performed, and histological examination of the resected specimens confirmed moderately differentiated adenocarcinomas of the rectum with metastases to the regional lymph nodes. The other colorectal polyps were tubular adenomas with no evidence of malignancy. Germline mutations in the APC gene were observed in codons 486, 545, 1493, and 1556. This case serves to demonstrate that a total proctocolectomy with ileoanal anastomosis should be the procedure of choice for young patients found to have advanced rectal cancer associated with FAP.

Abstract
OBJECTS This study was designed to detect possible alterations in the expression of neurotrophins and trks in kaolin-induced hydrocephalus by in situ hybridization. METHODS AND RESULTS Sixteen rats were treated by injection of 25 mg kaolin suspended in 0.1 ml of physiological saline into the cisterna magna. Four rats were injected with saline and served as controls. The kaolin-treated rats were divided into two groups studied 1 and 4 weeks after treatment. Rats were anesthetized and killed, and their brains were rapidly dissected and frozen. DNA oligonucleotide probes for nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and trkA, trkB, and C were labeled with [(35)S]dATP using terminal deoxyribonucleotidyl transferase for in situ hybridization. Hydrocephalic brains were also classified according to the degree of ventricular enlargement. The results observed were as follows. (1) The medial septal and striatal NGF mRNA levels increased with severity in animals. (2) Hippocampal trkB and BDNF mRNA levels increased with time in animals with moderate ventricular enlargement. (3) Expression of hippocampal trkB, trkC, and NT-3 mRNA increased in animals with moderate ventricular enlargement, while it apparently decreased in the large ventricular enlargement group reaching normal ranges. (4) In the corpus callosum there was an apparent increase in NGF, NT-3 and trkC mRNA, but not in trkA, in hydrocephalic animals. NT-3 EIA confirmed the presence of NT-3 protein increases in corpus callosum. It is therefore possible that simultaneous NGF, NT-3, and trkC receptor upregulation occurred in glial elements of the white matter. CONCLUSIONS These results demonstrate that neurotrophins and their receptors are overexpressed in many damaged structures of the severely hydrocephalic brain. There were discrepancies in the distribution of NGF and trkA mRNA, and we hypothesize that NGF mRNA in the damaged white matter structure might be due to the reduced availability of other receptors, such as the low-affinity NGF receptors.

Abstract
The problem of the low frequency of homologous recombination observed in higher plants has been approached in several ways. Here, we report a new strategy to enhance homologous recombination in Arabidopsis. In Escherichia coli and Saccharomyces cerevisiae, hotspots that enhance homologous recombination nearby have been identified in regions close to sites associated with the blocking of DNA replication forks or with intensive transcriptional activity. In yeast, a recombination hotspot (HOT1) was found in a region spanning two non-transcribed spacers (NTS) between ribosomal RNA genes (rDNA), which contains both a replication fork barrier ( RFB) and the promoter for transcription of the 35S rRNA gene. Since rDNA has a common structure among eukaryotes, we analyzed the effect of the endogenous NTS on homologous mitotic recombination in a higher plant. We constructed transgenic lines of Arabidopsis containing this NTS and a recombination substrate, in which two 3'- and 5'-deleted uidA (beta-glucuronidase) genes with partially overlapping sequences are separated by a Hyg(r) gene. Reconstitution of functional uidA genes by homologous recombination was monitored by histochemical GUS staining. We found that recombination occurred more frequently in all organs tested in F (Fork block) lines transgenic for the NTS than in C (Control) lines without the NTS. The average number of GUS+ spots on leaves in F lines was more than nine-fold higher than in C lines. Furthermore, by genomic Southern analysis, post-recombinational molecules were detected in a transgenic line, F43, which had an extremely high number of GUS+ blue spots. These results strongly suggest that NTS-dependent enhancement of homologous recombination may be a common feature of higher plants as well as yeast.

Abstract
Serological and histological studies were carried out to explore the role of the lectin complement pathway in the pathogenesis of cryoglobulinemic glomerulonephritis. Sixteen patients with mixed cryoglobulinemia type II with glomerulonephritis (GN) were enrolled. All cases had hepatitis C virus (HCV) infection. The serum concentration of mannose-binding lectin (MBL) was significantly higher in the GN patients than in the normal controls according to ELISA (P < 0.01). IgG, IgM, C1q, C4d, HCV envelope antigen, MBL, and MBL-associated serine protease-1 (MASP-1) could be visualized in the cryoprecipitate of the 16 patients by Dot blot assay. Renal biopsy specimens obtained from 3 patients were examined by immunohistochemistry, and the glomeruli strongly stained for IgG, IgM, MBL, MASP-1, C4d, C3c, and C3d in a fringe-like pattern. The pattern of HCV constituent deposition was partially fringe-like. The complement profiles of the 16 cases were distinctive; briefly, the serum levels of C1q, C2, and C3 were reduced, although the levels of circulating regulatory proteins (C1-inhibitor, factor H, and factor I) were in the normal range. The serum C4 level was significantly reduced. These results indicate that immune complex formation involves molecules of the lectin pathway and leads to organ damage in cryoglobulinemic glomerulonephritis.

Abstract
Renal blood flow decreases with the progression of chronic glomerulonephritis (CGN). This disease induces medullary ischemia and further renal dysfunction in patients with chronic renal insufficiency (CRI). Prostacyclin (PGI2), with its vasodilative action, increases renal blood flow (RBF) without increasing glomerular filtration rate (GFR). We therefore examined the possibility that PGI2 would mitigate the progression of renal dysfunction by increasing RBF in patients with CRI. Sixteen patients with progressive renal insufficiency (serum creatinine: 2.14+/-0.89 mg/dl) due to CGN were prospectively chosen for this study. The blood pressure was already under control using calcium channel blockers before and during this study in nine hypertensive patients. In the first 6 months the patients received a low-protein (0.6 g/kg/day) and low-salt (5.0 g/day) diet. In the next 6 months they received 60 microg/day of PGI2 analogue (Beraprost sodium) orally. GFR was determined by 24-hour creatinine clearance, and effective renal plasma flow (ERPF) was determined by 99mTc-MAG3 scintigraphy. Glomerular capillary pressure, the resistance ratio of afferent and efferent arterioles (R(A)/R(E)), and the other hemodynamic parameters from Gomez's estimation equation were determined at the start of this study, just before the administration of Beraprost and at the end of the study. The levels of GFR and ERPF were 34.6+/-12.4 and 140.6+/-52.1 ml/min at the start of this study respectively, and decreased to 28.0+/- 12.0 and 115.6+/-45.3 ml/min after the first 6 months without Beraprost. The levels of GFR and ERPF stayed at 28.1+/-15.7 and 119.2+/-57.6 ml/min after the next 6 months with Beraprost in the same patients. R(A)/R(E) increased in the first 6 months from 7.9+/-3.6 to 10.8+/-8.6, but remained constant during 6 months of Beraprost administration, at 10.5+/-8.0. These data indicate that PGI2 analogue diminishes the vascular resistance of glomerular afferent and efferent arterioles regulating the decrease of renal blood flow without glomerular hyperfiltration, thus mitigating the progression rate of renal dysfunction.

Abstract
We compared clinical outcomes in hydrocephalic patients and observed variation in the rate of flow in ventriculoperitoneal shunts with changes in posture in 231 separate examinations of shunt flow in 148 patients. A small cadmium telluride detector was placed over the shunt reservoir, and clearance of radioisotope injected into the reservoir was recorded as a measure of flow. Flow rate tended to increase during head elevation. Four patterns of radioisotope clearance were seen: type I, no flow; type II, adequate flow with moderate opening pressure; type III, adequate flow with low opening pressure; and type IV, excessive flow. This categorisation reflected clinical shunt function. Our method effectively assesses flow rate with the patient in a variety of postures or during movement, yielding useful information for adjustment of shunt valve pressure.
