Abstract
INTRODUCTION Although breast milk is considered the optimal nutrition for infants, it is also the primary cause of postnatal cytomegalovirus (CMV) infection. Preterm infants with postnatal CMV infections are susceptible to a variety of life-threatening conditions. CASE SUMMARY Twin male infants were delivered via emergency caesarian section at 27 weeks' gestation secondary to maternal complete uterine rupture. The Apgar scores at 1 and 5 min were 1 and 1 for the older twin (Twin A) and 0 and 3 for the younger twin (Twin B). Their birth weights were 1203 g (+ 0.65SD) and 495 g (- 3.79SD) respectively. On day 41, laboratory blood test results for Twin B showed a moderate elevation in C-reactive protein (CRP), thrombocytopenia. CMV quantitative polymerase chain reaction (qPCR) tests in Twin B's urine and blood as well as in the mother's breast milk were positive, but stored, dried umbilical cord CMV qPCR tests were negative. Twin B was diagnosed with a postnatal CMV infection secondary to infected breast milk and ganciclovir was commenced on day 52. Treatment was switched to valganciclovir at 74 days of age, but a negative CMV-DNA level in the blood was not achieved. Postnatal CMV infection in this infant led to an exacerbation of pre-existing bronchopulmonary dysplasia (BPD) and he demised at 182 days of age. CONCLUSION Postnatal cytomegalovirus infections may lead to exacerbations of BPD. Early use of raw breast milk in preterm infants should be done with careful consideration of this potential complication.

Abstract
(1) Background: Dental caries, if diagnosed at the initial stage, can be arrested and remineralized by a non-operative therapeutic approach preserving tooth structure. Accurate and reproducible diagnostic procedure is required for the successful management of incipient caries. The aim of this study was to evaluate the diagnostic accuracy of 3D swept-source optical coherence tomography (3D SS-OCT) for enamel caries at smooth tooth surface if the lesion was with remineralization. (2) Methods: Forty-seven tooth surfaces of 24 extracted human teeth visibly with/without enamel caries (ICDAS code 0−3) were selected and used in this study. The tooth surfaces of investigation site were cleaned and visually examined by four dentists. After the visual inspection, SS-OCT scanning was performed onto the enamel surfaces to construct a 3D image. The 2D tomographic images of the investigation site were chosen from the 3D dataset and dynamically displayed in video and evaluated by the examiners. A five-rank scale was used to score the level of enamel caries according to the following; 1: Intact enamel. 2: Noncavitated lesion with remineralization. 3: Superficial noncavitated lesion without remineralization. 4: Deep nonvacitated lesion without remineralization. 5: Enamel lesion with cavitation. Sensitivity and specificity for 3D OCT image and visual inspection were calculated. Diagnostic accuracy of each diagnostic method was calculated using weighted kappa. Statistical significance was defined at p = 0.05. (3) Results: 3D SS-OCT could clearly depict enamel caries at smooth tooth surface as a bright zone, based on the increased backscattering signal. It was noted that 3D SS-OCT showed higher sensitivity for the diagnosis of remineralized lesions and deep enamel lesions without cavitation, as well as cavitated enamel lesions (p < 0.05). No significant difference of specificity was observed between the two diagnostic methods (p > 0.05). Furthermore, 3D SS-OCT showed higher diagnostic accuracy than visual inspection (p < 0.05). (4) Conclusions: Within the limitations of this in vitro study, 3D SS-OCT showed higher diagnostic capacity for smooth surface enamel caries than visual inspection and could also discriminate lesion remineralization of enamel caries.

Abstract
AIM To clarify the prevalence and degree of maternal microchimerism in Japanese children with type 1 diabetes, as well as its effect on phenotypic variation. METHODS We studied 153 Japanese children with type 1 diabetes, including 124 children positive for β-cell autoantibodies, and their 71 unaffected siblings. The number of circulating microchimeric cells per 105 host cells was estimated by the use of quantitative-polymerase chain reaction targeting non-transmitted maternal human leukocyte antigen alleles. The results were compared to previous data from white European people. Phenotypic comparison was performed between maternal microchimerism carriers and non-carriers with diabetes. RESULTS Maternal microchimerism was detected in 15% of children with autoantibody-positive type 1 diabetes, 28% of children with autoantibody-negative type 1 diabetes, and 16% of unaffected siblings. There were no differences in the prevalence or levels of maternal microchimerism among the three groups or between the children with type 1 diabetes and their unaffected siblings. Furthermore, maternal microchimerism carriers and non-carriers exhibited similar phenotypes. CONCLUSIONS Maternal microchimerism appears to be less common in Japanese children with type 1 diabetes than in white European people. Our data indicate that maternal microchimerism is unlikely to be a major trigger or a phenotypic determinant of type 1 diabetes in Japanese children and that the biological significance of maternal microchimerism in type 1 diabetes may differ among ethnic groups.

Abstract
BACKGROUND Recently, heterozygous RFX6 mutations including p.Arg377Ter were identified in individuals with maturity-onset diabetes of the young (MODY). Clinical analysis of 36 individuals suggested that RFX6 mutation-induced MODY is characterized by low penetrance and relatively late onset. However, given the small number of previous reports and the limited clinical information of each case, further studies are necessary to clarify the phenotypic characteristics of RFX6 mutations. CASE REPORT We identified a previously reported p.Arg377Ter variant of RFX6 in a three-generation family with diabetes. The variant was detected through mutation screening for 30 diabetes-associated genes. The variant was not found in public databases and was predicted to encode a truncated protein or undergo nonsense-mediated mRNA decay. The proband showed glycosuria from 8 years of age and was diagnosed with MODY at 10 years of age, before the onset of puberty. She received basal and bolus insulin injection as initial therapy. The proband's mother exhibited glycosuria at 26 years of age when she conceived the first child. The mother was treated with insulin, oral hypoglycaemic drugs and diet. The proband and her mother were negative for islet cell autoantibodies. The maternal grandmother showed glycosuria around 50 years of age and was treated with oral hypoglycaemic drugs alone. CONCLUSION This study provides supporting evidence for the causal relationship between heterozygous RFX6 mutations and MODY. Furthermore, our results indicate that phenotypic consequences of RFX6 mutations are highly variable even within a single family, and possibly include childhood-onset and pregnancy-associated non-autoimmune diabetes.

Abstract
BACKGROUND The hepatic clearance of endotoxin (Et) may reflect hepatic functional reserve and ischemic injury to hepatocytes. Therefore, we examined the relationships between Et activity (EA) and the metrics Pediatric End-Stage Liver Disease (PELD)/Model of End-Stage Liver Disease (MELD) score and alanine transaminase (ALT) levels in the postoperative period. METHODS We performed 8 living-donor liver transplantations (LDLTs) for biliary atresia at our center from April 2012 to December 2012. EA was measured by means of an Et activity assay (EAA) in samples collected from a vein 1 day before LDLT, from the portal vein during the intraoperative anhepatic phase, from an artery 1 hour after reperfusion, from an artery on postoperative day (POD) 1, and from an artery or vein at PODs 7 and 14. RESULTS EAs generally remained at low levels. EA at the reperfusion period was significantly lowest. The correlation coefficient for the preoperative MELD/PELD score and the EAA was 0.837, and the corresponding P value was .009; thus, there was a significant relationship between the preoperative MELD/PELD score and the EAA. The correlation coefficients for ALT at POD 1 and EA during the anhepatic phase, at 1 hour after reperfusion, and at POD 1 were 0.64, 0.43, and 0.38, respectively, and the P values for these correlations were .08, .67, and .34. Thus, we observed that ALT and EA generally tended to be somewhat directly correlated, but no significant relationships between these 2 metrics were observed. CONCLUSIONS Endotoxin metabolism reflects the hepatic functional reserve capacity of end-stage liver disease.

Abstract
BACKGROUND Antibody drugs have been used to treat steroid-resistant rejection (SRR) after liver transplantation. Although anti-thymocyte globulin has been used for SRR after liver transplantation in place of muromonab-CD3 since 2011 in Japan, the effectiveness of anti-thymocyte globulin after pediatric living-donor liver transplantation (LDLT) has not yet been reported. The aim of this study was to evaluate the effectiveness of antibody drug treatment for SRR after pediatric LDLT in our single center. METHODS Between May 2001 and December 2013, 220 pediatric LDLTs were performed. Initial immunosuppression after LDLT included tacrolimus and methylprednisolone therapy. Acute rejection was diagnosed by use of a liver biopsy and the administration of steroid pulse treatment, and SRR was defined as acute rejection refractory to the steroid pulse treatment. RESULTS Acute rejection and SRR occurred in 74 (33.6%) and 16 patients (7.3%), respectively. The graft survival rates of non-SRR and SRR were 92.4% and 87.5%, respectively (P = .464). The median concentration of alanine aminotransferase before and after the administration of antibody drug was 193.5 mU/mL (range, 8-508) and 78 mU/mL (range, 9-655), respectively (P = .012). The median rejection activity index before and after the administration of antibody drugs was 5 (range, 2-9) and 1 (range, 0-9), respectively (P = .004). After antibody drug treatment, 12 patients had cytomegalovirus infections, 2 patients had Epstein-Barr virus infections, 3 patients had respiratory infections, and 1 patient had encephalitis. The cause of death in 1 patient with SRR was recurrence of infant fulminant hepatic failure. CONCLUSIONS Antibody drug treatment for SRR after pediatric LDLT is safe and effective.

Abstract
BACKGROUND Although there have been a few reports describing the changes of graft liver and spleen volumes after liver transplantation (LT), little is known about the relationship between graft liver function and the changes of these volumes after technical variant liver transplantation (TVLT). We therefore performed a retrospective study to investigate the relationship between graft liver function and these volumes after TVLT. METHODS We retrospectively investigated the cases of 140 TVLT procedures that were performed in our department between July 1987 and October 2012 and in which follow-up was conducted at our department. We calculated the graft liver volume to standard liver volume (GV/SLV) ratio, the spleen volume to standard spleen volume (SV/SSV) ratio, and the spleen volume to graft liver volume (S/L) ratio by CT volumetry. We clarified the relationship between graft liver function (according to the pathological findings) and the graft liver and spleen volumes at 2, 5, and 10 years after TVLT. RESULTS In the normal liver function group, the GV/SLV, SV/SSV, and S/L ratios decreased until 6 months after TVLT and then converged at 10 years after TVLT to 0.95, 1.27, and 0.27, respectively. In the graft liver failure group, the GV/SLV, SV/SSV, and S/L ratios at 10 years after TVLT were 0.67, 5.01, and 1.55, respectively. A significant correlation was observed between the GV/SLV ratio and the presence of mild liver fibrosis at 2 and 5 years after TVLT (P = .03 and P = .04, respectively). CONCLUSIONS Post-transplant CT-volumetry is a noninvasive and effective means of evaluating graft liver status.

Abstract
To solve the unpleasant disposal of greywater in rural area and allow its collection for reuse in gardening, a slanted soil treatment system (SSTS) was designed and installed in two households. Granitic gravel of 1-9 mm size was used as the filter medium. The aim of this study was to design a SSTS and assess its suitability as a treatment system allowing greywater reuse in gardening. The efficiency of the SSTS was assessed based on organic matter and bacterial pollution removal. The developed SSTS allowed the collection of greywater from three main sources (shower, dishwashing and laundry) in rural area. The SSTS is efficient in removing at least 50% of suspended solids, chemical oxygen demand and biological oxygen demand. The study highlighted that, contrary to the common perception, greywater streams in rural area are heavily polluted with faecal indicators. The removal efficiency of faecal indicators was lower than 2 log units, and the bacteriological quality of the effluents is generally higher than the WHO reuse guidelines for restricted irrigation. Longer retention time is required to increase the efficiency. The possibility of reusing the treated greywater as irrigation water is discussed on the basis of various qualitative parameters. The SSTS is a promising greywater treatment system for small communities in the rural area in the Sahelian region. To increase the treatment efficiency, future research will focus on the characteristics of the SSTS, the grain size and the establishment of a pretreatment step.

Abstract
This study was carried to assess the effect of a mixture of salts, urea and creatinine on water evaporation from urine using an on-site volume reduction system in long-term experiments. Subsequently, the fate of nitrogen during volume reduction of urine was also assessed. The water evaporation rate, salt accumulation in the gauze sheet, concentrations of urea and ammonia-N, and pH of urine were measured periodically. Based on the results, a mass balance of nitrogen in concentrated urine was calculated for a moderate evaporating condition. The results revealed that steady-state evaporation was observed throughout the experiment period without any inhibition due to salt accumulation. Salt concentration in the gauze sheet reached steady-state illustrating the possibility of salt falling back to the tank from the sheet. No significant reduction of urea was observed for a moderate evaporating condition, which indicates inhibition of urea hydrolysis by the high concentration of the mixture of salts, urea and creatinine in the urine. In contrast, for a low evaporating condition, the pH of the urine increased to 8.9, which indicates early urea hydrolysis, causing an offensive odour and ammonia loss to the air. In simple storage experiments, a mixture of salts, urea and creatinine amounting to 227-334 g L(-1) in urine inhibited urea hydrolysis, even with faecal contamination, at 25 degrees C, while urine samples containing a mixture of salts, urea and creatinine at less than 227 g L(-1) did not provide strong inhibition of hydrolysis.

Abstract
OBJECTIVES To describe our experience with 126 consecutive living-donor liver transplantation (LDLT) procedures performed because of biliary atresia and to evaluate the optimal timing of the operation. PATIENTS AND METHODS Between May 2001 and January 2010,126 patients with biliary atresia underwent 130 LDLT procedures. Mean (SD) patient age was 3.3 (4.2) years, and body weight was 13.8 (10.7) kg. Donors included 64 fathers, 63 mothers, and 3 other individuals. The left lateral segment was the most commonly used graft (75%). Patients were divided into 3 groups according to body weight: group 1, less than 8 kg (n = 40); group 2,8 to 20 kg (n = 63); and group 3, more than 20 kg (n = 23). Medical records were reviewed retrospectively. Follow up was 4.5 (2.7) years. RESULTS All group 3 donors underwent left lobectomy, and all group 1 donors underwent left lateral segmentectomy. No donors required a second operation or died. Comparison of the 3 groups demonstrated that recipient Pediatric End-Stage Liver Disease score in group 1 was highest, operative blood loss in group 2 was lowest (78 mL/kg), and operative time in group 3 was longest (1201 minutes). Hepatic artery complications occurred more frequently in group 1 (17.9%), and biliary stenosis (43.5%) and gastrointestinal perforation (8.7%) occurred more frequently in group 3. The overall patient survival rates at 1, 5, and 9 years was 98%, 97%, and 97%, respectively. Five-year patient survival rate in groups 1,2, and 3 were 92.5%, 100%, and 95.7%, respectively. Gastrointestinal perforation (n = 2) was the primary cause of death. CONCLUSIONS Living-donor liver transplantation is an effective treatment of biliary atresia, with good long-term outcome. It seems that the most suitable time to perform LDLT to treat biliary atresia is when the patient weighs 8 to 20 kg.

Abstract
BACKGROUND There have been few reports on the management of intra-abdominal drains after living donor liver transplantation (LDLT). We retrospectively investigated changes in ascitic data related to management of an intra-abdominal drain. PATIENTS AND METHODS Between March 2008 and June 2009, we performed 28 LDLT. On the first and the fifth postoperative day (POD) after LDLT, we examined the number of ascites cells and cell fractions as well as performed biochemical examination and cultures. RESULTS The day of removal of the drain for massive ascites (10 mL/kg/d or more) was 14.2 ± 5.4 POD; for less than 10 mL/kg/d it was 8.7 ± 1.9 POD (P < .001). Nine patients were ascites culture positive; long-term placement of the drain caused an infection in two patients. CONCLUSIONS When the amount of ascitic fluid on the fifth POD after LDLT was small, it was important to assess the properties of the ascitic fluid because of the possibility of a drain infection or of poor drainage. If the ascitic neutrophil count is less than 250/mm(3) or the examined ascites is normal, intra-abdominal drains should be removed.

Abstract
The prognosis of liver transplantation for neonates with fulminant hepatic failure (FHF) continues to be extremely poor, especially in patients whose body weight is less than 3 kg. To address this problem, we have developed a safe living donor liver transplantation (LDLT) modality for neonates. We performed LDLTs with segment 2 monosubsegment (S2) grafts for three neonatal FHF. The recipient age and body weight at LDLT were 13-27 days, 2.59-2.84 kg, respectively. S2 or reduced S2 grafts (93-98 g) obtained from their fathers were implanted using temporary portacaval shunt. The recipient portal vein was reconstructed at a more distal site, such as the umbilical portion, to have the graft liver move freely during hepatic artery (HA) reconstruction. The recipient operation time and bleeding were 11 h 58 min-15 h 27 min and 200-395 mL, respectively. The graft-to-recipient weight ratio was 3.3-3.8% and primary abdominal wall closure was possible in all cases. Although hepatic artery thrombosis occurred in one case, all cases survived with normal growth. Emergency LDLT with S2 grafts weighing less than 100 g can save neonates with FHF whose body weight is less than 3 kg. This LDLT modality using S2 grafts could become a new option for neonates and very small infants requiring LT.

Abstract
BACKGROUND Stat3 is a member of the Janus-activated kinase/STAT signalling pathway. It normally resides in the cytoplasm and can be activated through phosphorylation. Activated Stat3 (p-Stat3) translocates to the nucleus to activate the transcription of several molecules involved in cell survival and proliferation. The constitutive activation of Stat3 has been shown in various types of malignancies, and its expression has been reported to indicate a poor prognosis. However, the correlation between the constitutive activation of Stat3 and the prognosis of cervical cancer patients has not been reported. METHODS The immunohistochemical analysis of p-Stat3 expression was performed on tissues from 125 cervical squamous-cell carcinoma patients who underwent extended hysterectomy and pelvic lymphadenectomy, and the association of p-Stat3 expression with several clinicopathological factors and survival was investigated. RESULTS Positive p-Stat3 expression was observed in 71 of 125 (56.8%) cases and was significantly correlated with lymph node metastasis, lymph vascular space invasion, and large tumour diameter (>4 cm) by Fisher's exact test. Kaplan-Meier survival analysis showed that p-Stat3 expression was statistically indicative of a poor prognosis for overall survival (P=0.006) and disease-free survival (P=0.010) by log-rank test. CONCLUSION These data showed that p-Stat3 expression in cervical cancer acts as a predictor of poor prognosis.

Abstract
Spot urine samples were collected from the inhabitants of two rural communities in northwestern Bangladesh. We compared arsenic levels in the urine samples ([As](u); n = 346) with those in water from tube wells ([As](tw); range < 1-535 microg/L; n = 86) on an individual basis. The small variation of [As](u) within subjects and highly positive correlation with [As](tw) indicate that [As](u) is a useful indicator of exposure. Analyses of [As](u) showed that creatinine correction was necessary, that [As](u) only reflected recent exposure, and that there were substantial interindividual differences for a given [As](tw) level. To evaluate the toxic effects of arsenic exposure, we constructed a system for rating skin manifestations, which revealed distinct sex-related differences. Comparison of males and females in the same households confirmed that skin manifestations were more severe in the males, and in the males of one community a dose-response relationship between [As](u) and the degree of skin manifestation was evident. The results of this study indicate that [As](u) in spot urine samples can be used as an exposure indicator for As. They suggest that there might be sex-related, and perhaps community-related, differences in the relationship between [As](u) and skin manifestations, although several confounding factors, including sunlight exposure and smoking habits, might contribute to the observed sex difference. The existence of such differences should be further confirmed and examined in other populations to identify the subpopulations sensitive to chronic arsenic toxicity.

Abstract
We report anesthetic management of a 13-year-old boy with Beckwith-Wiedemann syndrome for urethral fistulectomy using propofol-fentanyl anesthesia. The syndrome has three major symptoms; exomphalos, macroglossia and gigantism. Other complications including neonatal hypoglycemia, visceromegaly, metabolic disorders, malignant tumors, and cardiovascular abnormalities may also be seen. This patient was complicated with gigantism, exomphalos, hypospadias, cryptorchidism, hepatoblastoma, accessory mammae, and left axis deviation with left anterior fascicular block. A comprehensive preoperative examination should include assessment of the airway, cardiovascular conditions, endocrine status, blood glucose, and electrolytes. In this patient, airway management was easy by laryngeal mask airway and the anesthetic course was uneventful.

Abstract
We analyzed genetic alterations in BRCA1 and BRCA2 genes among 82 ovarian cancer families in Japan. The clinical characteristics of BRCA-associated ovarian cancer patients were compared with cases carrying no mutations as well as with population controls. Using a direct sequencing method, 45 of the 82 ovarian cancer families were found to carry BRCA1 or BRCA2 germ-line mutations (40 with BRCA1 and 5 with BRCA2). In 24 independent mutations of BRCA1, 5 recurrent mutations were found and 2 of them, the L63X and Q934X mutations, were detected in seven and eight independent families, respectively. In addition, 16 mutations of BRCA1 and 3 mutations of BRCA2 have never been described previously. In consideration of clinicopathological features, there was a significantly higher proportion of tumors with serous adenocarcinoma and of cases of advanced stages in the BRCA1 or BRCA2 cases than in those of the controls. On the other hand, there were no differences of mean age at diagnosis between patients with BRCA1 or BRCA2 mutation and those of the controls. Our results indicate that the features of BRCA-associated ovarian cancer in Japan appear to be similar to those in Western countries, and the L63X and Q934X mutations of BRCA1 appear to be common founder mutations unique to the Japanese population.

Abstract
To investigate the role of placental transport of bile acids in fetal bile acid metabolism, such as with regard to synthesis of the unusual bile acids (1 beta- and 6 alpha-hydroxylated and unsaturated bile acids), we measured the concentrations of bile acids in umbilical cord blood, amniotic fluid, maternal serum and maternal urine at delivery by means of gas chromatography-mass spectrometry. Serum and urine from healthy nonpregnant women were used as controls. We detected large amounts of unusual bile acids, especially hyocholic acid and 3 beta-hydroxy-delta 5 bile acids, in amniotic fluid and umbilical cord blood. The concentration of total bile acids in maternal serum was less than that of control serum and umbilical cord blood, and the concentration of total bile acids in maternal urine was higher than that of control urine and amniotic fluid. In conclusion, the fetus synthesized large amounts of unusual bile acids, and these compounds were transported from fetus to mother by placental transfer. We suggest that pregnant women may excrete large amounts of bile acids into the urine to control serum concentration of bile acids in fetus.

Abstract
We have previously shown that RNA cleaving reagents with imidazole and primary amine groups on the 5'-end of antisense oligodeoxyribonucleotides could site-specifically cleave CpA as the target sequence of the substrate tRNA in vitro. In this study, a RNA cleaving reagent, composed of imidazole and primary amine groups on an antisense phosphorothioate oligonucleotide (Im-anti-s-ODN), was synthesized and evaluated for anti-HIV-1 activity in MT-4 cells. The sequence of the Im-anti-s-ODN was designed to be complementary to the HIV-1 gag-mRNA and to bind adjacent to the CpA cleavage site position. Im-anti-s-ODN encapsulated with the transfection reagent, DMRIE-C, had higher anti-HIV-1 activity than the unmodified antisense phosphorothioate oligonucleotide (anti-s-ODN) at a 2 microM concentration. Furthermore, the Im-anti-ODN encapsulated with DMRIE-C conferred sequence-specific inhibition.

Abstract
BACKGROUND Intensifying the dose of paclitaxel given in a weekly schedule is useful towards improving the therapeutic index of paclitaxel in treating a variety of advanced and recurrent malignancies and is suitable for outpatient administration. This pilot study was carried out to evaluate the safety of weekly paclitaxel administration by 1 h infusion in the outpatient setting. METHODS Eleven patients with recurrent gynecological tumors who had previously been treated with at least one platinum-based chemotherapy regimen participated in the study between May 1999 and March 2000. Paclitaxel was given at a dose of 70 mg/m(2 ) as a 1 h infusion every week for at least 20 consecutive weeks unless lesions became progressive. Intravenous dexamethasone and cimetidine and oral diphenhydramine were administered 30 min before paclitaxel infusion. RESULTS The 11 patients received a total of 166 cycles of therapy. All patients received 70 mg/m(2 ) doses of paclitaxel without treatment delay. No hypersensitivity reactions were elicited. Grade 3 or 4 leukopenia and neutropenia occurred in 9 and 36% of the patients, respectively. Granulocyte colony-stimulating factor was required for only one patient and no patients experienced febrile neutropenia. Neurotoxicity was the most serious adverse effect and all patients experienced grade 1 or 2 peripheral neuropathy. Grade 1 or 2 myalgias were observed in 45% of the patients. Alopecia was universal. No Grade 3 or higher non-hematological toxicities were observed. CONCLUSION Weekly 1 h paclitaxel administration is considered safe as a salvage therapy for recurrent gynecological tumors, making its use more convenient and easier in the outpatient setting. The current results support further evaluation.

Abstract
The present study investigated whether dantrolene, which inhibits the Ca(2+) release from the intracellular Ca(2+) store sites, reduced nuclear DNA fragmentation and produced neuronal protection in a model of global forebrain ischemia. Male Wistar rats were subjected to four-vessel occlusion (4VO) for 5 min and then infused continuously with dantrolene or vehicle into the cerebral ventricle for 3 days. The intact rats did not undergo any intervention. The number of viable and DNA nick-end-labeled neurons in the hippocampal CA1 were evaluated 4 days after the ischemia. The number of viable neurons in the dantrolene-treated rats was significantly higher than that in the vehicle-treated rats and lower than that in the intact animals (P<0.01 and <0.05, respectively). The number of DNA nick-end-labeled nuclei was significantly lower in dantrolene-treated rats compared with the vehicle-treated animals (P<0.0001). No nick-end labeling was observed in the intact animals. A linear correlation was found between the number of viable cells and nick-end labeled nuclei in the CA1 (r=0.91, P<0.0001). These results suggest that the postischemic intraventricular dantrolene is effective in precluding neuronal death and concomitant nuclear DNA fragmentation following transient global ischemia.

Abstract
We performed genome-wide linkage analysis in 58 patients and nine unaffected members among 28 families with no mutation in BRCA1 or BRCA2, employing a set of 410 microsatellite markers. We initially screened the whole genome, including the X chromosome, by a non-parametric method using the GENEHUNTER program. As a result, chromosome 3p22-p25 showed a suggestive score for linkage [LOD = 3.49 and non-parametric LOD (NPL) = 2.77 at D3S3611] based on a multipoint analysis. Additionally, based on a two-point analysis using dense markers, this 3p22-p25 region showed a P-value < 0.05 at 10 markers and there is suggestive evidence for linkage at two markers within approximately 19 cM (NPL = 2.60 and 2.49 at D3S1597 and D3S3611, respectively). To explore whether the candidate gene in this 3p22-p25 region contributed to carcinogenesis of familial ovarian cancer in a similar fashion to the tumor suppressor gene, we performed loss of heterozygosity (LOH) analysis. It was observed that the frequency of LOH at four markers in this region was >50% only in tumor tissues from patients with no mutation in BRCA1 or BRCA2, not in those with a BRCA1 mutation.

Abstract
Almond has a self-incompatibility system that is controlled by an S locus consisting of the S-RNase gene and an unidentified "pollen S gene." An almond cultivar "Jeffries," a somaclonal mutant of "Nonpareil" (S(c)S(d)), has a dysfunctional S(c) haplotype both in pistil and pollen. Immunoblot and genomic Southern blot analyses detected no S(c) haplotype-specific signal in Jeffries. Southern blot showed that Jeffries has an extra copy of the S(d) haplotype. These results indicate that at least two mutations had occurred to generate Jeffries: (1) deletion of the S(c) haplotype and (2) duplication of the S(d) haplotype. To analyze the extent of the deletion in Jeffries and gain insight into the physical limit of the S locus region, approximately 200 kbp of a cosmid contig for the S(c) haplotype was constructed. Genomic Southern blot analyses showed that the deletion in Jeffries extends beyond the region covered by the contig. Most cosmid end probes, except those near the S(c)-RNase gene, cross-hybridized with DNA fragments from different S haplotypes. This suggests that regions away from the S(c)-RNase gene can recombine between different S haplotypes, implying that the cosmid contig extends to the borders of the S locus.

Abstract
We report the use of paclitaxel in the successful treatment of a patient with recurrent adenocarcinoma of the cervix. Paclitaxel, 70 mg/m2 by 1-h infusion weekly, was administered to a 59-year-old patient with cervical adenocarcinoma showing lung metastasis. She showed partial clinical response after seven cycles, and at the completion of 20 cycles she showed complete response, which was confirmed by chest X-ray and computed tomography scan. Toxicities including neurotoxicity were mild. She showed an objective response to treatment for over 8 months, and she enjoyed a favorable quality of life during and after treatment. Weekly paclitaxel was very well tolerated, yet was effective for recurrent cervical adenocarcinoma.

Abstract
In 40 females undergoing gynecologic laparotomy, lumbar epidural analgesia using a disposable infusion pump was continued for postoperative 48 hours. Then the analgesic effect of epidural bupivacaine (4.8 mg.kg-1) plus fentanyl (12 micrograms.kg-1) diluted with normal saline was prospectively compared between the two groups; high concentration/low volume group (HC/LV, 96 ml of total volume and 2 ml.h-1 of infusion rate, n = 20) versus low concentration/high volume group (LC/HV, 240 ml of total volume and 5 ml.h-1 of infusion rate, n = 20). On postoperative day 1, LC/HV group showed the significantly lower visual analog scale and verbal pain score at rest than HC/LV group (P < 0.05). No significant differences in the incidence of side effects were observed between the groups. These results suggest that when the equivalent dose is given, the volume rather than the concentration of the solution is important for postoperative continuous epidural analgesia with the combination of bupivacaine and fentanyl.

Abstract
OBJECTIVE The aim of this study was to evaluate the toxicity and efficacy of weekly paclitaxel in patients with recurrent endometrial cancer. METHODS Paclitaxel (70 mg/m(2) by 1-h infusion weekly) was administered to two patients with recurrent endometrial cancer of the lung. RESULTS After 5 cycles, both patients with platinum-resistant disease achieved clinical partial responses confirmed by computed tomography (CT) scan. The serum CA125 levels of case 1 decreased to cut-off level. The response duration of both patients was 4 months. The toxicity was acceptable and probably less pronounced than that characterize of the standard tri-weekly schedules. CONCLUSION Although conclusions regarding survival are premature, weekly paclitaxel might offer better quality of life during treatment.
