Abstract
OBJECTIVE Metformin, a medicine used for the treatment of type 2 diabetes, was previously reported to suppress age-dependent hyperproliferation of intestinal stem cells in Drosophila. Here, we aimed to investigate its anti-aging effects on other tissues, such as adult muscle and elucidate the mechanisms underlying the anti-ageing effect. MATERIALS AND METHODS To evaluate the anti-muscle ageing effect of Metformin, we visualized ubiquitinated protein aggregates accumulated in adult muscle as the flies age by immunostaining and measured the total pixel size of the aggregates. We altered gene expression in the muscle by induction of dsRNA against the relevant mRNAs or mRNAs encoding the constitutively active mutant proteins using the Gal4/UAS system. We determined the mRNA levels by quantitative Real Time-Polymerase Chain Reaction (QRT-PCR). RESULTS Continuous metformin feeding significantly extended the lifespan of Drosophila adults. Furthermore, the feeding suppressed the aging-dependent accumulation of ubiquitinated aggregates in adult muscle. To delineate the mechanism through which metformin influences the muscle aging phenotype, we induced the constitutively active AMPK specifically in the muscles and found that the activation of the AMPK-mediated pathway was sufficient for the anti-aging effect of Metformin. Furthermore, the AMPK-mediated downregulation of Tor-mediated pathways, subsequent induction of an eIF-4E inhibitor were involved in the effect. These genetic data suggested that the metformin effect is related to the partial suppression of protein synthesis in ribosomes. Furthermore, metformin stimulated autophagy induction in adult muscles. CONCLUSIONS Our results suggest that metformin can be regarded as an anti-aging compound in Drosophila muscle. The stimulation of autophagy was also involved in the anti-aging effect, which delayed the progression of muscle aging in Drosophila adults.

Abstract
Abstract
Background
It remains unknown if concomitant left atrial appendage closure (LAAC) at the time of left ventricular assist device (LVAD) surgery can reduce ischemic cerebrovascular accidents.
Purpose
The purpose of this study is to assess the impact of LAAC at LVAD surgery on the incidence of ischemic cerebrovascular accidents.
Methods
Between January 2012 and November 2021, 310 patients underwent LVAD surgery with HeartMate II or III. Out of 310 patients, 98 patients (31.6%) underwent concomitant LAAC. The cohort was divided into two groups: patients with LAAC (Group A, n=98) and without LAAC (Group B, n=212). To minimize device bias, LVAD surgery with HeartWare HVAD device was excluded. The ischemic cerebrovascular accident was defined as ischemic stroke, hemorrhagic stroke or transient ischemic attack. We reviewed early and long-term clinical outcomes. The incidence of ischemic cerebrovascular accidents was compared between two groups using the Kaplan-Meier method. We also investigated if LAAC was associated with ischemic cerebrovascular accidents by Cox proportional hazards analysis.
Results
There were no significant differences in baseline characteristics between two groups including age (Group A: 55.0±12.3 years old, Group B: 56.9±14.1 years old, p=0.26), preoperative CHADS2 score (Group A: 2.40±1.1, Group B: 2.58±1.1, p=0.19) and history of atrial fibrillation (Group A: 42.9%, Group B: 42.5%, p=0.95). In-hospital mortality was not significantly different between the two groups (Group A: 7.1%, Group B: 12.3%, p=0.16). In terms of postoperative complications, there were no significant differences between two groups in requiring extracorporeal membrane oxygenation, re-exploration for bleeding and newly required hemodialysis. Median follow up period was 474 days. Thirty-five patients (11.2%) developed ischemic cerebrovascular accidents (5 patients in Group A and 30 patients in Group B). The rate of freedom from ischemic cerebrovascular accidents in Group A (94.1% at 500 days and 94.1% at 1500 days) was significantly higher than that in Group B (88.2% at 500 days and 77.4% at 1500 days; log rank=0.024). In a Cox proportional hazards regression analysis including LAAC, age, history of atrial fibrillation, diabetes mellitus and Heartmate 3 device implantation, LAAC was associated with reducing the incidence of ischemic cerebrovascular accidents (hazard ratio 0.37, 95% CI 0.13–0.89, p=0.02).
Conclusion
Concomitant LAAC at the time of LVAD surgery can reduce ischemic cerebrovascular accidents without increasing perioperative mortality and complications.

Abstract
BACKGROUND Although immunotherapy is thought to be a promising cancer treatment, most patients do not respond to immunotherapy. In this post hoc analysis of a phase 1/2 study, associations of programmed death ligand 1 (PD-L1), PD-L2, and HLA class I expressions with responses to dendritic cells (DCs)-based immunotherapy were investigated in patients with advanced sarcoma. METHODS This study enrolled 35 patients with metastatic and/or recurrent sarcomas who underwent DC-based immunotherapy. The associations of PD-L1, PD-L2, and HLA class I expressions in tumor specimens, which were resected before immunotherapy, with immune responses (increases of IFN-γ and IL-12) and oncological outcomes were evaluated. RESULTS Patients who were PD-L2 (+) showed lower increases of IFN-γ and IL-12 after DC-based immunotherapy than patients who were PD-L2 (-). The disease control (partial response or stable disease) rates of patients who were PD-L1 (+) and PD-L1 (-) were 0% and 22%, respectively. Disease control rates of patients who were PD-L2 (+) and PD-L2 (-) were 13% and 22%, respectively. Patients who were PD-L1 (+) tumors had significantly poorer overall survival compared with patients who were PD-L1 (-). No associations of HLA class I expression with the immune response or oncological outcomes were observed. CONCLUSIONS This study suggests that PD-L1 and PD-L2 are promising biomarkers of DC-based immunotherapy, and that addition of immune checkpoint inhibitors to DC-based immunotherapy may improve the outcomes of DC-based immunotherapy.

Abstract
Abstract
Background
Although transthoracic Doppler echocardiography is widely used for estimating left ventricular stroke volume (SV), accelerated blood flow in the left ventricular (LV) outflow tract may lead to overestimation. SV can be calculated accurately from left ventricular end-systolic and end-diastolic volume determined by multi-detector computed tomography (MDCT). However, radiation exposure as well as the use of contrast medium hampers its routine use.
Purpose
The purpose of this study was to examine whether the correction of SV measured by pulsed wave Doppler echocardiography (SVdop) can accurately predicts SV obtained by MDCT (SVct).
Methods: We enrolled consecutive 61 patients who underwent both MDCT and transthoracic echocardiography. Patients with moderate or severe valvular diseases and valve replacement surgery were excluded. Correction of SV was explored with SVct as a reference.
Results: Univariate analysis showed that SVdop (r = 0.42, P = 0.0007) and patient age (r=-0.50, P < 0.0001) were significantly correlated with SVct. On the other hand, left ventricular ejection fraction calculated by Teicholz method (EFteich) (r = 0.19, P = 0.14), systolic blood pressure (r = 0.07, P = NS), and LV mass index (r=-0.02, P = NS) were not correlated with SVct. Multivariate analysis showed that SVdop, patient age and EFteich were the independent predictive factors for SVct (R2 = 0.49, P < 0.0001). Based on these correlations, we postulated SV as: corrected SV = SVdop × 0.40 + EFteich × 0.46 – age × 0.67 + 44.77. As expected, the correlation between corrected SV and SVct significantly improved (r = 0.70, P < 0.0001). Bland-Altman plot analysis showed that corrected SV significantly reduced the variation between SVdop and SVct, and diminished the overestimation of SVdop (Figure).
Conclusion: The new correction formula of SVdop may correct the overestimation of SV obtained by pulsed wave Doppler echocardiography, although the formula remains to be validated in a separate cohort of patients.

Abstract
Abstract
Background
Although transplantation of human Adipose-derived Mesenchymal stem cell (hADSC) shows efficacy in the treatment of ischemic cardiomyopathy, its therapeutic mechanisms have not been fully elucidated. It has been already reported that mitochondria transfer to recipient cells have impact on resistance to injury and tissue regeneration, however this phenomenon has not been elucidated in the damaged heart. Therefore, we hypothesized that ADSC transfer own mitochondria to cardiomyocytes in-vivo and in-vitro under ischemic condition, resulting in the functional recovery of cardiomyocyte.
Method and result
Transplantation of hADSC (group A) to the heart surface or sham operation (group C) was performed in rats that were subjected to LAD ligation 2 weeks prior to the treatment (n=10 each). The number of transplant cell was 1x106/body. Three days after transplantation, transferred hADSCs' mitochondria were observed in recipient cardiomyocytes histologically (Figure). Quantitative PCR analysis revealed that mitochondrial genome of recipient myocytes increased over time. The cardiac function assessed with echocardiography was significantly better in group A. Furthermore, live-imaging of hADSC transplantation revealed the suspected transfer of mitochondria to beating heart.
In-vitro, the co-culture of rat cardiomyocytes (rCM) and hADSC was observed with time-lapse photography and demonstrated mitochondrial transfer under the hypoxic condition. The measuring the oxygen consumption rate (OCR) of these cells showed that OCR of rCM was reinforced by co-culture with hADSC conspicuously.
Figure 1
Conclusion
Mitochondrial transfer from hADSC to rCM was suggested in-vivo and in-vitro ischemic condition and suspected to be related to functional recovery of ischemic cardiomyocyte.

Abstract
We evaluated the effects of intraarterial injection of Adriamycin/Mitomycin C oil (Lipiodol) suspension (ADMOS) alone and ADMOS + cis-diaminodichloroplatinum (CDDP) in 135 patients with hepatocellular carcinoma (HCC). A total of 59 patients received ADMOS alone and 76 patients received ADMOS + CDDP (ADMOS/CDDP). Tumor size was reduced by over 25% in 13 (34%) of the evaluable 38 patients in the ADMOS-alone group and in 39 (51%) of the 76 evaluable patients in the ADMOS/CDDP group. Serum alpha-fetoprotein (AFP) levels decreased by more than 50% in 10 (59%) of 17 ADMOS-alone patients and in 23 (70%) of 33 ADMOS/CDDP patients whose pretreatment AFP levels were above 0.2 mg/l. The overall one- and 2-year survival rates were 68% and 41%, respectively. No severe complications and no significant changes in laboratory values were observed, except for one patient in the ADMOS/CDDP group who developed a liver abscess. Although the tumor response was significantly better in patients treated by ADMOS/CDDP than in those treated by ADMOS-alone (p < 0.05), there was no significant difference in the survival rates between the 2 groups. The intraarterial injection of ADMOS and CDDP was concluded to be effective in treating HCC judging by tumor response.

Abstract
A 57-year-old man with a history of hepatitis B virus infection was referred to our hospital for living-donor liver transplantation (LDLT). Five years earlier, right lobectomy had been performed for solitary hepatocellular carcinoma (HCC) with bile duct tumor thrombus in segments 5 and 6 in the liver. Two years later, transarterial chemoembolization and radiofrequency ablation were performed for recurrent HCC. Two years after those local therapies, another recurrent HCC was treated with transhepatic arterial infusion chemotherapy with cisplatin and conventional radiation therapy (RT) with 60 Gy in 20 fractions, because the tumor was contiguous to the trunk of the portal vein. After the completion of RT, symptoms due to liver failure and severe infection caused by multiple liver abscesses developed despite the administration of antibiotics and percutaneous transhepatic cholangiodrainage. Therefore, LDLT was performed with the use of a right lobe graft donated by his wife. Vascular anastomosis was successfully performed with the use of normal procedures. The patient recovered uneventfully, and has since been doing well for 34 months, with no evidence of vascular complications. However, the degree of injury to the anastomotic vessels caused by definitive RT before LDLT remains unclear, whereas the safety and efficacy of some forms of RT as a bridge to deceased-donor LT have been reported. Salvage LDLT is effective for patients with liver failure after multidisciplinary treatment including radiation, while carefully taking radiation-induced vessel injury as a potential late complication into consideration, especially in LDLT cases.

Abstract
Objective: The aim of this study was to compare the biocompatibility of a new Senko E-Ternal coating (SEC) for cardiopulmonary bypass (CPB) circuits with the well-established poly-2-methoxyethyl acrylate (PMEA) coating. Methods: Forty patients undergoing aortic valve replacement were randomly assigned to either an SEC-coated group (n = 20) or a PMEA-coated group (n = 20). Clinical data and the following markers were analyzed: platelet count, platelet factor (PF) 4, fibrinogen, fibrinogen degradation products (FDPs), antithrombin III (AT III), thrombin-antithrombin complex (TAT), plasminogen, complement hemolytic activity (CH50), complement 3 (C3) and interleukin-6 (IL-6). Blood samples were obtained at five time points in both groups. Results: CPB time, aortic cross-clamp time and blood loss and transfusion were similar in both groups. There were no significant differences between the groups in terms of platelet count, PF4 and all coagulation and fibrinolytic parameters (FDP, AT III, TAT, and plasminogen) at any time points. Inflammatory markers (CH50, C3 and IL-6) were also similar in both groups at all time points. Conclusions: The SEC-coated circuit demonstrated equivalent biocompatibility to the PMEA-coated circuit. SEC-coated circuits are, therefore, favorably comparable to PMEA-coated circuits for clinical use in CPB.

Abstract
In response to sustained damage to a kidney, fibrosis that can be characterized as the deposition of a collagenous matrix occurs and consequently causes chronic kidney failure. Because most animals used in experiments synthesize ascorbic acid (AsA) from glucose, the roles of AsA in fibrotic kidney diseases are largely unknown. Unilateral ureteric obstruction (UUO) mimics the complex pathophysiology of chronic obstructive nephropathy and is an ideal model for the investigation of the roles of AsA in kidney failure. We examined the impact of a deficiency of Akr1a, a gene that encodes aldehyde reductase and is responsible for the production of AsA, on fibrotic damage caused by UUO in mice. Oxidatively modified DNA was elevated in wild-type and Akr1a-deficient kidneys as a result of UUO to a similar extent, and was only slightly suppressed by the administration of AsA. Even though Akrla-deficient mice could produce only about 10% of the AsA produced by wild-type mice, no difference was observed in collagen I synthesis under pathological conditions. The data implied either a low demand for AsA or the presence of another electron donor for collagen I production in the mouse kidney. Next, we attempted to elucidate the potential causes for oxidative damage in kidney cells during the fibrotic change. We found decreases in mitochondrial proteins, particularly in electron transport complexes, at the initial stage of the kidney fibrosis. The data imply that a dysfunction of the mitochondria leads to an elevation of ROS, which results in kidney fibrosis by stimulating cellular transformation to myofibroblasts.

Abstract
In 1999, we developed a technique for biological reconstruction after excision of a bone tumour, which involved using autografts of the bone containing the tumour treated with liquid nitrogen. We have previously reported the use of this technique in 28 patients at a mean follow up of 27 months (10 to 54). In this study, we included 72 patients who underwent reconstruction using this technique. A total of 33 patients died and three were lost to follow-up, at a mean of 23 months (2 to 56) post-operatively, leaving 36 patients available for a assessment at a mean of 101 months 16 to 163) post-operatively. The methods of reconstruction included an osteo-articular graft in 16, an intercalary in 13 and, a composite graft with prosthesis in seven. Post-operative function was excellent in 26 patients (72.2%), good in seven (19.4%), and fair in three (8.3%) according to the functional evaluation system of Enneking. No recurrent tumour occurred within the grafts. The autografts survived in 29 patients (80.6%), and the rates of survival at five and ten years were 86.1% and 80.6 %, respectively. Seven of 16 osteo-articular grafts (44%) failed because of fracture or infection, but all the composite and intercalary grafts survived. The long-term outcomes of frozen autografting, particularly using composite and intercalary grafts, are satisfactory and thus represent a good method of treatment for patients with a sarcoma of bone or soft tissue.

Abstract
Mechanisms of cell specification of mesenchyme during ascidian embryogenesis are poorly understood. This is because no good molecular markers have been available to evaluate differentiation of the mesenchyme cells. To obtain molecular markers of mesenchyme differentiation, we established monoclonal antibodies, Mch-1 and Mch-3, that recognize antigens present in the mesenchyme cells of the larva of Halocynthia roretzi. The antigens recognized by both antibodies start to be detectable in the mesenchyme cells at the late tailbud stage. The Mch-3 antibody specifically recognized all mesenchyme cells of the larva, whereas the Mch-1 antibody stained the cells only in the anterior portions of mesenchyme clusters in the trunk region of the larva. The Mch-1 antibody also stained trunk lateral cells. In addition, both antibodies recognized the mesenchyme cells in the ventro-lateral boundary between endoderm and epidermis that are migrating to the anterior head region of the larva. The partial embryos that originated from the mesenchymelineage cells at the 8-cell stage expressed the Mch-1 and Mch-3 antigens. The Mch-1 and Mch-3 antibodies will be useful as immunological probes for studying the specification mechanisms of mesenchyme cells.

Abstract
A study was carried out to examine modifying effects of Maharishi Amrit Kalash 4 (MAK 4) and Maharishi Amrit Kalash 5 (MAK 5) on phagocytic and digestive functions of macrophages in male ICR mice. Mice at 4 week of age were divided into 3 groups: no treatment group (control), MAK 4 treated group (MAK 4 group) and MAK 5 treated group (MAK 5 group). MAK 4 and MAK 5 were given p.o. at 50 mg/kg per day (5 days/week) for 7 weeks. Phagocytic function of reticuloendothelial system evaluated by the carbon clearance was enhanced by the treatment of MAK 4 and MAK 5. Superoxide anion (O(2-)) production of peritoneal macrophages increased significantly in both MAK 4 and MAK 5 groups. The acid phosphatase activity of peritoneal macrophages increased significantly in MAK 4 group compared to the control group, but not in MAK 5 group. The activities of β-glucuronidase and lactate dehydrogenase in both MAK 4 and MAK 5 groups increased significantly when compared to the control group. These results suggest that MAK 4 and MAK 5 promote the phagocytic and digestive functions of macrophages and have a stimulatory effect on macrophages.

Abstract
OBJECTIVE Muscle-specific receptor tyrosine kinase (MuSK) antibody-positive myasthenia gravis (MG) accounts for 5%-15% of autoimmune MG. MuSK mediates the agrin-signaling pathway and also anchors the collagenic tail subunit (ColQ) of acetylcholinesterase (AChE). The exact molecular target of MuSK-immunoglobulin G (IgG), however, remains elusive. As acetylcholine receptor (AChR) deficiency is typically mild and as cholinesterase inhibitors are generally ineffective, we asked if MuSK-IgG interferes with binding of ColQ to MuSK. METHODS We used 3 assays: in vitro overlay of the human ColQ-tailed AChE to muscle sections of Colq-/- mice; in vitro plate-binding assay to quantitate binding of MuSK to ColQ and to LRP4; and passive transfer of MuSK-IgG to mice. RESULTS The in vitro overlay assay revealed that MuSK-IgG blocks binding of ColQ to the neuromuscular junction. The in vitro plate-binding assay showed that MuSK-IgG exerts a dose-dependent block of MuSK binding to ColQ by but not to LRP4. Passive transfer of MuSK-IgG to mice reduced the size and density of ColQ to ∼10% of controls and had a lesser effect on the size and density of AChR and MuSK. CONCLUSIONS As lack of ColQ compromises agrin-mediated AChR clustering in Colq-/- mice, a similar mechanism may lead to AChR deficiency in MuSK-MG patients. Our experiments also predict partial AChE deficiency in MuSK-MG patients, but AChE is not reduced in biopsied NMJs. In humans, binding of ColQ to MuSK may be dispensable for clustering ColQ, but is required for facilitating AChR clustering. Further studies will be required to elucidate the basis of this paradox.

Abstract
OBJECTIVE Autism appears to have a strong genetic component. The product of the NADH-ubiquinone oxidoreductase 1 alpha subcomplex 5 (NDUFA5) gene is included in the mitochondrial electron transport chain. METHOD We performed a case-control study of 235 patients with autism and 214 controls and examined three single-nucleotide polymorphisms (SNPs) within this gene in a Japanese population. We then conducted a transmission disequilibrium test (TDT) analysis in 148 autistic trios. RESULTS In the case-control study, two SNPs (rs12666974 and rs3779262) showed a significant association with autism (P=0.00064 and 0.00046 respectively). Furthermore, a haplotype containing these two SNPs showed a significant association (P-global=0.0013, individual haplotype A-A: P=0.010). In TDT analysis, the global and A-A haplotype P-values also indicated significant associations. Minor allele and genotype frequencies were decreased in the autistic subjects. CONCLUSION We found significant association between the NDFA5 gene and autism.

Abstract
Watanabe, Tsutomu (Keio University, Tokyo, Japan), Toshiya Takano, Toshihiko Arai, Hiroshi Nishida, and Sachiko Sato. Episome-mediated transfer of drug resistance in Enterobacteriaceae. X. Restriction and modification of phages by fi(-) R factors. J. Bacteriol. 92:477-486. 1966.-An fi(-) R factor, which restricts phages lambda, T1, and T7 without modifying them, was found to restrict and not to modify an F(-)-specific phage, W-31, in Escherichia coli K-12, but not to restrict phage P-22 in Salmonella typhimurium LT-2, whereas other fi(-) R factors restricted and modified P-22 but not W-31; fi(+) R factors did not restrict these phages. Transduction and lysogenization with phages lambda and P-22 were reduced by these fi(-) R factors in K-12 and LT-2, respectively, and the transducing phages lambda and P-22 were modified by these fi(-) R factors. Spontaneous as well as ultraviolet-induced production of phage P-22 and zygotic induction of phage lambda were not significantly affected by any R factor. Injection of the nucleic acids of phages T1 and lambda was not affected by R factors, but the injected phage nucleic acids were rapidly broken down in the bacteria carrying fi(-) R factors. The nucleic acids of the modified phages were not broken down in these bacteria. It was assumed from these results that the mechanism of restriction of phages by fi(-) R factors is due to the breakdown of the injected phage nucleic acids by a deoxyribonuclease(s), presumably located near the cell surface in the cells carrying fi(-) R factors. The deoxyribonuclease(s), formed in the cells carrying the nonmodifying fi(-) R factor, is considered to be different from that synthesized in the cells carrying the modifying fi(-) R factors. It was further shown that the average burst sizes of the unmodified as well as modified phages are slightly reduced by the presence of the fi(-) R factors.

Abstract
We evaluated the possible induction of a systemic immune response to increase anti-tumour activity by the re-implantation of destructive tumour tissue treated by liquid nitrogen in a murine osteosarcoma (LM8) model. The tumours were randomised to treatment by excision alone or by cryotreatment after excision. Tissue from the tumour was frozen in liquid nitrogen, thawed in distilled water and then re-implanted in the same animal. In addition, some mice received an immunological response modifier of OK-432 after treatment. We measured the levels of interferon-gamma and interleukin-12 cytokines and the cytotoxicity activity of splenocytes against murine LM8 osteosarcoma cells. The number of lung and the size of abdominal metastases were also measured. Re-implantation of tumour tissue after cryotreatment activated immune responses and inhibited metastatic tumour growth. OK-432 synergistically enhanced the anti-tumour effect. Our results suggest that the treatment of malignant bone tumours by reconstruction using autografts containing tumours which have been treated by liquid nitrogen may be of clinical value.

Abstract
Androgen plays a crucial role in initiating and maintaining the expression of male sexual characteristics in mammals. In humans and mice, any defects along the pathway of androgen functions result in congenital urogenital abnormalities. The genital tubercle (GT), an anlage of the external genitalia, differentiates into a penis in males and a clitoris in females. Although masculinization of the external genitalia is androgen-dependent, the molecular pathway of its potential downstream genes is largely unclear. To identify the genes involved in mouse GT masculinization, we performed gene expression analyses, such as real-time quantitative polymerase chain reaction and section in situ hybridization analysis. From our studies we have identified candidate genes, Cyp1b1, Fkbp51 and MafB as potential androgen targets during mouse GT masculinization.

Abstract
Split hand/foot malformation (SHFM) is syndromic ectrodactyly often associated with mental retardation and/or craniofacial defects. Several clinical reports previously described urogenital dysplasia such as micropenis, hypospadias, and small testis in SHFM patients. Genetic lesions in the Dlx5 and Dlx6 (Dlx5/6) locus are associated with the human genetic disorder SHFM type 1. Although Dlx5/6 are expressed in the testis, their possible function of Dlx5/6 during testis differentiation has not been described. In this study, we show that Dlx5/6 are expressed in the fetal Leydig cells during testis development. We examined the effect of Dlx5 expression on the promoter activation of the steroidogenic acute regulatory protein (StAR) gene, which is essential for gonadal and adrenal steroidogenesis, in a Leydig cell line. Dlx5 efficiently activates the StAR promoter when GATA-4, another transcription factor essential for testicular steroidogenesis, was coexpressed. The transcriptional activation required the GATA-4-recognition element in the StAR promoter region and Dlx5 can physically interact with GATA-4. Furthermore, we herein show that the double inactivation of Dlx5 and Dlx6 in the mouse leads to decreased testosterone level and abnormal masculinization phenotype. These results suggest that Dlx5 and Dlx6 participate in the control of steroidogenesis during testis development. The findings of this study may open the way to analyze human congenital birth defects.

Abstract
The identification of metabolites in the early stages of drug discovery is important not only for guiding structure-activity relationships (SAR) and structure-metabolism relationships (SMR) strategies, but also for predicting the potential for adverse events. The present study investigated the phase I metabolism of CJ-036878 (N-(3-phenethoxybenzyl)-4-hydroxybenzamide), a potent antagonist of the N-methyl-D-asparatate (NMDA) receptor, using liver microsomes and representative recombinant cytochrome P450 enzymes. The structures of the oxidative metabolites M1-M11 were confirmed by LC-UV/MS(n) and/or (1)H-nuclear magnetic resonance (NMR). It was found that CJ-036878 is metabolized through three routes: (1) aliphatic hydroxylation that generates M1 and M2; (2) aromatic hydroxylation that produces M3-M5, M7 and M8; and (3) dimerization through an oxidative phenol coupling reaction that yields M10 and M11. The use of recombinant human cytochrome P450 enzymes suggested that CYP3A4 is the major enzyme involved in the oxidative metabolism of CJ-036878, with minor contributions from CYP1A2, CYP2C19, and CYP2D6.

Abstract
CJ-036878, N-(3-phenethoxybenzyl)-4-hydroxybenzamide, was developed as an antagonist of the N-methyl-D-aspartate receptor NR2B subunit. Two dimeric metabolites, CJ-047710 and CJ-047713, were identified from the incubation mixture with CJ-036878 in human liver microsomes (HLM). The identification of the enzymes involved in the formation of these dimeric metabolites was investigated in the current study. Inhibition of the formation of CJ-047710 and CJ-047713 in pooled HLM by 1-aminobenztriazole, SKF-525A, and ketoconazole were observed. Ketoconazole played a significant role in inhibiting formation of these two metabolites in a concentration-dependent manner. Recombinant CYP3A4 and CYP3A5 exhibited a markedly high activity toward the formation of CJ-047710 and CJ-047713 from CJ-036878, but the contribution of other CYP enzymes to these formations was at a very low level or negligible. The formation of CJ-047710 and CJ-047713 in pooled HLM, CYP3A4, and CYP3A5 showed sigmoid characteristics. S50 values for CJ-047710 and CJ-047713 formation in HLM were almost equivalent with those for CYP3A4 and CYP3A5. For the CYP3A enzymes, maximal clearance due to auto-activation values for CJ-047710 and CJ-047713 formation catalysed by CYP3A5 were 3.6- and 3.1-fold higher than those catalysed by CYP3A4. This is the first report that shows both CYP3A4 and CYP3A5 simultaneously contribute to dimerization through oxidative C-C and C-O coupling reactions.

Abstract
We report a case of isolated extramedullary relapse of acute myeloid leukaemia (AML) that presented as granulocytic sarcoma of both breasts, with no other signs of relapse even in the bone marrow. The T2 weighted coronal images on MR showed both multiple ill-defined heterogeneous hyperintense masses relative to breast parenchyma; these masses were seen also with a visual washout enhancement. Pathohistological study showed infiltration by myeloblasts, which were relatively uniform in appearance, featuring round or oval nuclei and a small cytoplasm. After chemotherapy and radiotherapy, both breast masses disappeared on MR images. Although the MR findings of granulocytic sarcoma were indistinguishable from those of multicentric carcinoma and malignant lymphoma, the MR images were useful for evaluating and monitoring responses to the treatments, as well as for detecting non-palpable relapsed tumours.

Abstract
Antisense transcription (transcription from the opposite strand to a protein-coding or sense strand) has been ascribed roles in gene regulation involving degradation of the corresponding sense transcripts (RNA interference), as well as gene silencing at the chromatin level. Global transcriptome analysis provides evidence that a large proportion of the genome can produce transcripts from both strands, and that antisense transcripts commonly link neighboring "genes" in complex loci into chains of linked transcriptional units. Expression profiling reveals frequent concordant regulation of sense/antisense pairs. We present experimental evidence that perturbation of an antisense RNA can alter the expression of sense messenger RNAs, suggesting that antisense transcription contributes to control of transcriptional outputs in mammals.

Abstract
Infiltration by circulating inflammatory cells is a prominent local inflammatory feature of ulcerative colitis (UC). Several trials have suggested that leukocytapheresis by filtration can benefit patients with active UC. We investigated how this therapy might modulate the inflammatory response. Patients with active UC who were beginning repeated filtration leukocytapheresis were studied. Mononuclear cell preparations were obtained from blood before and after the first treatment, and expression of cytokine signalling components and the cell-proliferative response were analysed in vitro. Leukocytapheresis reduced lipopolysaccharide-induced production of proinflammatory cytokines (interleukin-1, -6, -8 and tumour necrosis factor-alpha, P < 0.05 for all) and activation of intracellular signalling components (nuclear factor-kappaB, mitogen-activated protein kinases, and signal transducer and activator of transcription-3), as well as surface expression of toll-like receptor-4 (P < 0.05) in mononuclear cells. The therapy also reduced the cell-proliferative response by mononuclear cells stimulated with sonicated bacterial preparations from autologous intestine (P < 0.05). These results indicate that activated mononuclear cells in the peripheral blood of patients with active UC are removed by leukocytapheresis and replaced by cells with a lower activation status. This replacement may partly explain the therapeutic benefit.

Abstract
Of 27,000 infants whose sleep-wake characteristics were studied under the age of 6 months, 38 died unexpectedly 2-12 weeks after the sleep recording in a pediatric sleep laboratory. Of these infants, 26 died of sudden infant death syndrome (SIDS), and 12 of definitely identified causes. The frequency and duration of sleep apneas were analysed. Sleep recordings and brainstem histopathology were studied to elucidate the possible relationship between sleep apnea and neuropathological changes within the arousal system. Immunohistochemical analyses were conducted using tryptophan hydroxylase (TrypH), a serotonin synthesizing enzyme, and growth-associated phosphoprotein 43 (GAP43), a marker of synaptic plasticity. The terminal-deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) method was used for apoptosis. The pathological and physiological data were correlated for each infant. In the SIDS victims, statistically significant positive correlations were seen between the number of TrypH-positive neurons in the dorsal raphe nucleus of the midbrain and the duration of central apneas (p = 0.03), between the number of TUNEL-positive glial cells in the pedunculopontine tegmental nucleus (PPTN) and the average number of spines in GAP43-positive neurons in the PPTN (p = 0.04). These findings in the dorsal raphe nucleus of the midbrain and PPTN, that play important roles in the arousal pathway suggest a possible link between changes in arousal and SIDS.
