Abstract
Ichthyological surveys have traditionally been conducted using whole-specimen, capture-based sampling with varied but conventional fishing gear. Recently, environmental DNA (eDNA) metabarcoding has emerged as a complementary, and possible alternative, approach to whole-specimen methodologies. In the tropics, where much of the diversity remains undescribed, vast reaches continue unexplored, and anthropogenic activities are constant threats; there have been few eDNA attempts for ichthyological inventories. We tested the discriminatory power of eDNA using MiFish primers with existing public reference libraries and compared this with capture-based methods in two distinct ecosystems in the megadiverse Amazon basin. In our study, eDNA provided an accurate snapshot of the fishes at higher taxonomic levels and corroborated its effectiveness to detect specialized fish assemblages. Some flaws in fish metabarcoding studies are routine issues addressed in natural history museums. Thus, by expanding their archives and adopting a series of initiatives linking collection-based research, training and outreach, natural history museums can enable the effective use of eDNA to survey Earth's hotspots of biodiversity before taxa go extinct. Our project surveying poorly explored rivers and using DNA vouchered archives to build metabarcoding libraries for Neotropical fishes can serve as a model of this protocol.

Abstract
BACKGROUND AND OBJECTIVES To treat organ transplant patients with mycobacterial infection, physicians need to pay attention to interaction between drugs used against mycobacteria and immunosuppressants. The purpose of this report is to describe the clinical features of and treatment for mycobacterial infection in lung transplant (LTx) recipients. METHODS To investigate the incidence, treatment, and outcome for mycobacterial infection, we retrospectively reviewed 100 LTx recipients in our program since 2000. RESULTS Four recipients (4.0%) developed mycobacterial infection. Three recipients took tacrolimus, and 1 received cyclosporine with mycophenolate mofetil and a steroid for immunosuppression. Tuberculosis (TB) was isolated from 2 recipients, and non-tuberculous mycobacteriosis (NTM) was detected in the other 2. We treated the patients with levofloxacin + isoniazid + pyrazinamide + ethambutol (EB) for TB and clarithromycin (CLM) + EB for NTM to avoid interaction of calcineurin inhibitors (CNI: 8-10 ng/mL in trough level) with rifampicin (RFP). In treating the patients with NTM, we were able to maintain an adequate blood concentration of CNI by decreasing the dosage from one-half to one-quarter. All mycobacterial infections were controlled with treatment. In 1 patient with chronic obstructive pulmonary disease (COPD) infected with TB in the native lung, the forced expiratory volume in 1 second (FEV1) unexpectedly increased from 1890 mL before infection to 2320 mL possibly due to organization of the native lung. CONCLUSIONS We were able to manage the mycobacterial infections using drugs other than RFP without any cases of acute rejection under adequate immunosuppression. Organization of the native lung with TB infection unexpectedly resulted in improvement of FEV1 in a COPD patient.

Abstract
INTRODUCTION There are several sets of criteria for the diagnosis of Amniotic Fluid Embolism (AFE), but little is known about their degree of agreement. AIM To evaluate the concordance of the Japan criteria for AFE in comparison with two definitions: the US AFE registration entry criteria (the US criteria) and UK Obstetric Surveillance System criteria for defining cases of amniotic fluid embolism (the UK criteria). MATERIALS AND METHODS A retrospective observational study was conducted in which the AFE cases registered in the Obstetrical Gynaecological Society of Kinki District in Japan for the period of April 2005 to December 2012 have been analysed by the expert steering obstetric committee, organized by the members of the Obstetric Research group. Cohen's kappa coefficient was used to calculate the agreement among three clinical diagnoses. For inter-group comparison, the Pearson Chi-square test was used (for categorical) and Mann-Whitney test was used (for continuous variables). RESULTS Among the 26 cases registered for this period, a total of 18 women were selected as having AFE according to the Japan criteria. Five women died (case fatality rate 27.8%). Agreement between the Japan criteria and the US and UK criteria was k = 0.453 and k = 0.538, respectively, reflecting moderate agreement. However, only 38.9% were given a diagnosis of AFE according to all three criteria. The factor that most often caused disagreement in diagnosis between the Japan criteria and the US criteria was "onset within 30 minutes postpartum". The UK criteria excluded "women with postpartum haemorrhage as the first presenting feature in whom there was no evidence of cardiorespiratory compromise". The case fatality rates in US and UK are higher than in Japan (50.0% and 38.5% vs 27.8%), but this did not result in a significant difference (p=0.497). CONCLUSION The groups of subjects identified as having AFE by the Japan criteria had a medium agreement with the US (k=0.453) or UK criteria (k=0.538). These three definition criteria identified different subgroups of patients. Such disagreement has serious implications for research and treatment.

Abstract
OBJECTIVE Previous studies have reported that concentrations of squamous cell carcinoma (SCC) antigen in amniotic fluid are extremely higher than that in the maternal serum. The aim of this study was to assess the potential clinical utility of vaginal fluid SCC level as a marker for diagnosing premature rupture of membranes (PROM). METHODS A case-control study was performed using patients admitted to Nara Medical University Hospital, delivery ward, from January 2011 to December 2012. The discriminatory potential of SCC assay was determined using 54 PROM and 108 gestational age-matched control vaginal fluid samples, in a 1:2 ratio. Levels of vaginal fluid SCC in patients with PROM and control pregnant women were quantified by an enzyme-linked immunosorbent assay. RESULTS The statistical results showed no correlation between gestational age and vaginal fluid SCC levels. There was no significant difference in vaginal fluid SCC levels between patients with PROM and those with control pregnant women (16156.5 ± 10495.8 ng/mL versus 15471.9 ± 11362.2 ng/mL, p = 0.467). CONCLUSION We conclude that SCC could not be regarded as a potential marker for diagnosis of PROM. SCC may be a physiologic constituent of the vaginal fluid during pregnancy.

Abstract
OBJECTIVE To determine the relationship between preterm labor and delivery, and the pH and buffer capacity of vaginal secretions. METHODS Between January 1, 2009 and March 31, 2012, two cohorts of patients at 22-36weeks of pregnancy were enrolled in a prospective cohort study at Nara Medical University Hospital, Japan. Patients experiencing preterm contractions and a control group of patients experiencing normal pregnancies were included. The pH and buffer capacity of vaginal secretions were measured and compared. RESULTS Of the 237 patients enrolled, 48 (20.3%) were experiencing symptoms of preterm labor and 189 (79.7%) were included in the control group. The pH was higher (P<0.001) and the buffer capacity was lower (P=0.0135) in the vaginal secretions of the patients experiencing preterm contractions compared with the control group. There was no difference in the pH and buffer capacity of the vaginal secretions of symptomatic patients who would experience preterm delivery and those who would not. Receiver operating characteristic curve analyses demonstrated that vaginal-secretion pH and buffer capacity could differentiate between patients experiencing preterm contractions and those not, but could not differentiate between patients who would experience preterm delivery and those who would not. CONCLUSION Vaginal-secretion pH and buffer capacity could be useful in diagnosing preterm labor; further studies are needed to determine potential practical diagnostic criteria.

Abstract
We developed a set of universal PCR primers (MiFish-U/E) for metabarcoding environmental DNA (eDNA) from fishes. Primers were designed using aligned whole mitochondrial genome (mitogenome) sequences from 880 species, supplemented by partial mitogenome sequences from 160 elasmobranchs (sharks and rays). The primers target a hypervariable region of the 12S rRNA gene (163-185 bp), which contains sufficient information to identify fishes to taxonomic family, genus and species except for some closely related congeners. To test versatility of the primers across a diverse range of fishes, we sampled eDNA from four tanks in the Okinawa Churaumi Aquarium with known species compositions, prepared dual-indexed libraries and performed paired-end sequencing of the region using high-throughput next-generation sequencing technologies. Out of the 180 marine fish species contained in the four tanks with reference sequences in a custom database, we detected 168 species (93.3%) distributed across 59 families and 123 genera. These fishes are not only taxonomically diverse, ranging from sharks and rays to higher teleosts, but are also greatly varied in their ecology, including both pelagic and benthic species living in shallow coastal to deep waters. We also sampled natural seawaters around coral reefs near the aquarium and detected 93 fish species using this approach. Of the 93 species, 64 were not detected in the four aquarium tanks, rendering the total number of species detected to 232 (from 70 families and 152 genera). The metabarcoding approach presented here is non-invasive, more efficient, more cost-effective and more sensitive than the traditional survey methods. It has the potential to serve as an alternative (or complementary) tool for biodiversity monitoring that revolutionizes natural resource management and ecological studies of fish communities on larger spatial and temporal scales.

Abstract
INTRODUCTION Brain stroke in pregnancy, one of the most emergency features in hypertensive pregnancy, was surveyed nationwide (1582 hospitals) and 184 cases (1-2 in 10000 birth) including 10 maternal deaths were reported in Japan (2006). Also in a developed country, co-work of obstetricians (OB) and neurosurgeons (NS) is not always cooperative and the situation stresses clinical workers in emergency maternal transfer. OBJECTIVES We performed a survey of obstetric and neurosurgery specialists in/around Nara Prefecture (1.3million population, placed in the middle of Japan and does not have remote rural area) about their understanding and preparation on brain stroke in pregnancy. A final aim of this study is to assess the problem in emergency care in pregnancy, especially in hypertensive disorder. METHODS Fifty-seven OB answered the first questionnaire (executed by NS [S.Y.]) in January 2011 by post. After the analysis, a new questionnaire was executed by OB (K.N.) and 70 answers were given by NS in October 2011. Items in the questionnaire are shown below. Agreements for use of the answers in this research were given by each respondent. RESULTS [Experience] Three OB (5.3%) and 32 NS (45.7%, 38 cases) experienced a brain stroke in pregnancy in their career. Four NS (10.5% of cases) faced maternal death, including brain hemorrhage after eclampsia. [Diagnosis] Symptoms that OB suspect of brain stroke were loss of consciousness > hemiplegia > headache, and hemiplegia > loss of consciousness > speech disorder in NS. [Hypertension and Brain Stroke] Sixty-four (92.8%) NS thought chronic hypertension as a risk factor of brain stroke in women in reproductive age, and 53 (75.7%) NS thought acute hypertension is. The target blood pressure in the treatment of brain stroke mostly indicated by NS was 140mm/Hg in systolic and 85mm/Hg in diastolic blood pressure. Medication for hypertension chosen by NS was calcium blocker (77.1%) and ARB (38.6%). [Emergency Transfer in Japan] In Japan, ER center to accept women with perinatal emergency is not enough stated. Once the transfer to the central hospital due to brain stroke in pregnancy is needed, a primary department to accept the patient must be decided. Forty-seven (82.7%) OB preferred the Obstetrics Department to be a primary receiver; on the other hand, 38 (56.7%) NS preferred the Neurosurgery Department and only 17 (25.3%) NS answered that obstetrics should be a primary department. Twelve (17.9%) NS answered that the both departments should work together from the beginning. CONCLUSION Japanese maternal mortality rate is one of the lowest in the world (3.1 per 100,000 birth; 2007), but it was revealed in this study that the maternal emergency system in pregnancy-unrelated disease is not well arranged. Even though emergency system varies between each country, this knowledge in confliction between OB and NS in this area may be useful when other countries need to maintain the ER performance in hypertensive disorder in pregnancy.

Abstract
Inflammation plays a role in the pathogenesis of endometriosis. Endometriosis-associated ovarian carcinogenesis might be promoted through oxidative stress-induced increased genomic instability, aberrant methylation, and aberrant chromatin remodeling, as well as mutations of tumor suppressor genes. Aberrant expression of ARID1A, PIK3CA, and NF-kB genes has been recognized as the major target genes involved in oxidative stress-induced carcinogenesis. HNF-1beta appears to play a key role in anti-oxidative defense mechanisms. We discuss the pathophysiologic roles of oxidative stress as somatic mutations as well as highly specific agents that effectively modulate these targets.

Abstract
Two histologic types, clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC), are the common histology in ovarian cancer patients who have associated endometriosis. However, both tumor types have distinct clinicopathological characteristics and molecular phenotypes. EAC is predominantly positive for estrogen receptor (ER), but CCC specifically exhibits lower ER expression. This study reviews the current understanding of the role of the ER information in the pathogenesis of CCC, as well as the English language literature for biochemical studies on ER expression and estrogenic action in CCC. The iron-mediated oxidative stress occurs due to repeated hemorrhage in endometriosis, then this compound oxidatively modifies genomic DNA and, subsequently, ER depletion may be observed. There are a number of factors that interfere with ER expression and estrogen activity, which include DNA methylation of the promoter region, histone deacetylation, heme and iron binding, chromatin remodeling and ubiquitin ligase activity. Loss of estrogen function may be a turning point in CCC progression and aggressiveness.

Abstract
BACKGROUND High-molecular weight (HMW)-adiponectin is an active multimer for insulin sensitivity and anti-inflammatory reactions. We compared the ratio of serum total and HMW-adiponectin with brain-type natriuretic peptide (BNP) and other adipocytokines in normal pregnancy and pregnancy-induced hypertension (PIH). Effect of BNP on the secretion of adiponectin from cultured adipocytes was also examined. METHODS The three study groups consisted of 44 non-pregnant women, 40 normal (healthy) pregnant women over 28weeks gestation and 29 patients with severe PIH. Adiponectin (protease-pretreated for HMW), BNP-N-terminal, leptin, and monocyte chemoattractant protein (MCP)-1 were measured with ELISA. Pre-adipocytes were differentiated to matured adipocytes and cultured with recombinant-BNP addition. RESULTS HMW-to-total adiponectin ratio (HMW-ratio) was lower in normal pregnancy than in non-pregnant, and significantly higher in PIH than normal pregnancies. BNP-N-terminal showed positive correlation with HMW-adiponectin and HMW-ratio. Leptin and MCP-1 showed positive correlation with HMW-adiponectin, but not with HMW-ratio. Adiponectin in the supernatant of adipocyte cultures and intracellular cyclic-GMP was increased in dose-dependent manner in response to BNP. CONCLUSION The observed increase in the HMW-adponectin ratio in subjects with PIH may reflect a functional increase of adiponectin in the pathophysiology of PIH. Additionally, this increase seemed to be related to BNP via stimulation of adipocytes.

Abstract
During early pregnancy, extravillous trophoblast (EVT) cells are exposed to very low pO(2) values. In this study, we investigated the proteolytic functions and invasiveness of human primary EVT cells under hypoxic conditions to show the early placental pathophysiology. Placental samples (from 5 to 10 weeks gestation) were obtained at termination of pregnancy. Cytotrophoblast cells were separated by Percoll(®) gradient method and cultured on Matrigel(®) to obtain an invasive phenotype (similar to EVT). The invasion capacity (Matrigel-coated invasion assay), migration of the cells (wound healing assay), activity and expression of matrix metalloproteinase (MMP)-2 and tissue inhibitor for MMP (TIMP)-2 (gelatin gel zymography, ELISA, and quantitative RT-PCR), and expression of membrane-type (MT)1-MMP (western blot) were investigated. All cultures (except for quantitative RT-PCR) were performed under 20% oxygen, 5% oxygen, and 5% oxygen with 3 repetitions of 0.1% oxygen hypoxic stimulation for 1 h. Invasion and MMP2 activity of the cells were significantly increased in 20% and decreased in 0.1% oxygen. There was no significant difference in cell migration among the oxygen environments. Concentrations of MMP2 in the supernatant and expression of MT1-MMP were increased in both the 0.1% and 20% oxygen environments. The MMP2 mRNA level was increased after 1-h stimulation with 0.1% oxygen. The TIMP2 concentration was increased only in 20% oxygen, but the mRNA level was decreased in 0.1% oxygen. These results suggested that hypoxia might inhibit the invasive capacity and MMP2 activation of EVT cells in the early first trimester of pregnancy. Decrease in TIMP2 production may reduce the MMP2/TIMP2/MT1-MMP complex and lead to this unique behavior of EVT cells under hypoxic conditions.

Abstract
The patient was a 68 year-old woman who had a history of treatment of pulmonary tuberculosis 35 years ago. She has experienced dyspnea and hemosputa since several years ago and has been followed up as having chronic empyema. She was admitted to our hospital due to recent exacerbation of symptoms. X-ray films and computed tomography scans of the chest showed the right thoracic cavity to be totally filled with a mass and the shift of mediastinum to the left side. After several days from admission, she needed mechanical ventilation support due to dyspnea exacerbation. Emergency decortication with right pneumonectomy through median sternotomy with anterolateral incision was performed. Postoperative course was uneventful. Pathlogical diagnosis was chronic expanding hematoma.

Abstract
Recent data have provided information regarding the profiles of clear cell carcinoma of the ovary (CCC) with adenine-thymine rich interactive domain 1A (ARID1A) mutations. The purpose of this review was to summarize current knowledge regarding the molecular mechanisms involved in CCC tumorigenesis and to describe the central role played by the aberrant chromatin remodeling. The present article reviews the English-language literature for biochemical studies on the ARID1A mutation and chromatin remodeling in CCC. ARID1A is responsible for directing the SWI/SNF complex to target promoters and regulates the transcription of certain genes by altering the chromatin structure around those genes. The mutation spectrum of ARID1A was enriched for C to T transitions. CCC and clear cell renal cell carcinoma (ccRCC) resemble each other pathogenetically. Dysfunction of the ARID1A protein, which occurs with VHL mutations in ccRCC, is responsible for loss of the assembly of the ARID1A-mediated histone H2B complex. Therefore, ARID1A acts as a chromatin remodeling modifier, which stimulates cell signaling that can lead to cell cycle arrest and cell death in the event of DNA damage. The dysfunction of ARID1A may result in susceptibility to CCC carcinogenesis through a defect in the repair or replication of damaged DNA.

Abstract
Secondary spontaneous pneumothorax (SSP) such as lymphangioleiomyomatosis (LAM), bronchiolitis obliterans (BO) is intractable or repeated the recurrence of pneumothorax. The most effective chemical pleurodesis for intractable pneumothorax is talc poudrage and so on that is associated with a reduction in the rate of pneumothorax recurrence. However, severe and broad pleural adhesion due to the pleural interventional procedures sometimes cause serious bleeding when the patients undergo lung transplantation. We must be considered for new approaches to these intractable secondary pneumothoraces which replaced traditional conservative and surgical approaches. We had proposed new 2 approaches of total pleural covering (TPC) and awake surgical intervention (ASI) for intractable pneumothorax. We applied the TPC modified with coverage of air leak points with polyglycolic acid (PGA) sheet to 5 patients with intractable bilateral pneumothorax to reduce the risk of excessive bleeding by chemical pleurodesis in lung transplantation. The bilateral pneumothorax was well controlled, and no recurrence has been observed. TPC is reliable procedure for management intractable bilateral SSP. For 12 high-risk patients with other underling pulmonary diseases on general poor conditions, a surgical intervention was performed in awake condition. The air leaks were stopped in 11 cases except for 1 case. The recurrence of pneumothorax after surgery was 2 cases. ASI for intractable secondary pneumothorax can be applicable to selected patients with deteriorated general condition.

Abstract
Problem Preeclampsia, a pregnancy-specific hypertensive syndrome, is one of the leading causes of premature births as well as fetal and maternal death. Preeclampsia lacks effective therapies because of the poor understanding of disease pathogenesis. The aim of this paper is to review molecular signaling pathways that could be responsible for the pathogenesis of preeclampsia. Method of study This article reviews the English-language literature for pathogenesis and pathophysiological mechanisms of preeclampsia based on genome-wide gene expression profiling and proteomic studies. Results We show that the expression of the genes and proteins involved in response to stress, host-pathogen interactions, immune system, inflammation, lipid metabolism, carbohydrate metabolism, growth and tissue remodeling was increased in preeclampsia. Several significant common pathways observed in preeclampsia overlap the datasets identified in TLR (Toll-like receptor)- and RAGE (receptor for advanced glycation end products)-dependent signaling pathways. Placental oxidative stress and subsequent chronic inflammation are considered to be major contributors to the development of preeclampsia. Conclusion This review summarizes recent advances in TLR- and RAGE-mediated signaling and the target molecules, and provides new insights into the pathogenesis of preeclampsia.

Abstract
BACKGROUND Various theories try to explain the development and progression of endometriosis, however, no single theory can explain all aspects of this disorder. Gene expression profiling studies might reveal factors that explain variability in disease development and progression, which can serve as specific biomarkers for endometriosis and novel drug development. We have recently showed that the upregulated genes were predominantly clustered in stress and detoxification, providing a mechanistic explanation for the oxidative stress and chronic inflammatory response in endometriosis. OBJECTIVE This review aims: (1) to analyse the published data, with the aim of identifying pathways consistently regulated by the endometriosis genotype and (2) to summarise the findings of specific genes, which are involved in the process of oxidative stress and inflammation. METHODS We identified gene array and proteomics studies whose data were accessible in PubMed. RESULTS A major finding is the increased expressions of several markers including heat shock protein, S100, fibronectin, and neutrophil elastase, which might be involved in the process of Toll-like receptor (TLR)-dependent sterile inflammation. The study reviews a convergence in the main pathogenic process, where the TLR-mediated inflammation occurs possibly through the endogenous ligands. CONCLUSIONS In conclusion, a circulus vitiosus of both the oxidative stress pathway and the TLR pathways is generated when the process becomes chronic (danger signal spiral).

Abstract
Endometriosis affects an estimated 10% of women in the reproductive-age group. Here, we review current knowledge on molecular genesis of endometriosis-associated epithelial ovarian carcinoma (EOC). This article reviews the English language literature for biology, pathogenesis, and pathophysiological studies on endometriosis-associated EOC. Although endometriosis generally remains a benign condition, it demonstrates somatically acquired genetic alterations. Clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC) are the most frequent types of EOC associated with endometriosis. Retrograde menstruation or ovarian hemorrhage carries highly pro-oxidant factors, such as iron, into the peritoneal cavity or ovarian endometrioma. CCC and EAC should be considered separately in studies of endometriosis-associated EOC. The repeated events of hemorrhage in endometriosis can contribute to carcinogenesis and progression via 3 major processes: 1) increasing oxidative stress promotes DNA methylation; 2) activating anti-apoptotic pathways supports tumor promotion; and 3) aberrant expression of stress signaling pathways contributes to tumor progression. This review summarizes recent advances in the understanding of epidemiology, carcinogenesis, pathogenesis, and pathophysiology of endometriosis-associated EOC; and a possible novel model is proposed.

Abstract
OBJECTIVE Individuals with inflammation have a myriad of pregnancy aberrations including increasing their preterm birth risk. Toll-like receptors (TLRs) and receptor for advanced glycation end products (RAGE) and their ligands were all found to play a key role in inflammation. In the present study, we reviewed TLR and RAGE expression, their ligands, and signaling in preterm birth. RESEARCH DESIGN AND METHODS A systematic search was performed in the electronic databases PubMed and ScienceDirect up to July 2010, combining the keywords "preterm birth," "TLR", "RAGE", "danger signal", "alarmin", "genomewide," "microarray," and "proteomics" with specific expression profiles of genes and proteins. RESULTS This paper provides data on TLR and RAGE levels and critical downstream signaling events including NF-kappaB-dependent proinflammatory cytokine expression in preterm birth. About half of the genes and proteins specifically present in preterm birth have the properties of endogenous ligands "alarmin" for receptor activation. The interactions between the TLR-mediated acute inflammation and RAGE-mediated chronic inflammation have clear implications for preterm birth via the TLR and RAGE system, which may be acting collectively. CONCLUSIONS TLR and RAGE expression and their ligands, signaling, and functional activation are increased in preterm birth and may contribute to the proinflammatory state.

Abstract
Epithelial ovarian cancer (EOC) is the most common cause of gynecological cancer-related mortality. Clear cell EOC (cEOC) has a number of clinical features distinguishing it from other EOC because of frequent concurrence of endometriosis and highly chemoresistant nature resulting in a poor prognosis. Recent biochemical studies based on genome-wide expression analysis technology have noted specific expression of a transcription factor, hepatocyte nuclear factor-1beta (HNF-1beta), in cEOC and genetic alteration may be involved in oxidative stress. We describe the HNF-1beta-dependent pathophysiology of cEOC and discuss its role in oxidative stress-induced carcinogenesis. A systematic search was performed in the electronic databases PubMed and ScienceDirect up to July 2009, combining the keywords, genome-wide, microarray, epithelial ovarian cancer, clear cell carcinoma, oxidative stress, and detoxification, with specific expression profiles of genes. The catalog of cEOC-specificity might be a manifestation of six essential alterations in cell physiology: oxidative stress and detoxification, proteases, signal transduction, adhesion, transcription, and metabolism. Among 54 genes highly upregulated in cEOC, 47 genes (87.0%) were associated with the redox-related genes. Several important cEOC-related genes overlap with those known to be regulated by HNF-1beta. Twenty-two (40.7%) of the 54 genes predominantly identified in cEOC were involved in downstream targets of HNF-1beta. The HNF-1beta-dependent pathway might provide new insights into regulation of glycogen synthesis, detoxification and resistance to anticancer agents. This review summarizes recent advances in the understanding of oxidative stress and antioxidant mechanisms in pathogenesis of cEOC. A redox-sensitive subset of cEOC genes linked to oxidative and detoxification pathways was identified and associated with HNF-1beta-specific downstream targets.

Abstract
Extended thymectomy is an effective treatment of myasthenia gravis. In recent years, technological development of endoscopy enables it by thoracoscopic method instead of trans-sternal approach. We perform thoracoscopic extended thymectomy via 4 trocars introduced in bilateral pleural cavity with sternum lifting method through a small incision on epigastric region. The most difficult parts in this procedure are the dissection of the left brachiocephalic vein, especially around the thymic veins and the resection of superior poles of thymus. The rate of perioperative complications by thoracoscopic approach shows no significant differences from the one by the trans-sternal operation. This technique is less invasive than trans-sternal extended thymectomy and it makes the hospital stay after the operation shorter. Since thoracoscopic extended thymectomy is a new technique, the follow-up period of the patients who underwent it for myasthenia gravis is not long enough to evaluate the effectiveness to myasthenia gravis. It is not yet shown whether the long-term results for myasthenia gravis by thoracoscopic extended thymectomy are equal to the ones by trans-sternal technique.

Abstract
Surgical approach is one of the most crucial aspects in the treatment of superior sulcus tumor (SST). Posterior approach as described by Paulson and coworkers is appropriate for the resection of SST invading posterior part of the 1st rib and the vertebrae, whereas anterior approaches as described by Masaoka, Dartevelle, Grunenwald, or Rusca are suitable for resection of SST involving subclavian vessels. We present 2 cases of SST who underwent complete resection through the posterior approach and a modified hemi-clamshell approach, respectively. We also discuss the surgical approaches for SST with referring to literatures.

Abstract
PROBLEM Clear cell carcinoma (CCC) of the ovary has a number of features distinguishing it from other epithelial ovarian carcinomas (EOC) because of its characteristic histology and biology, frequent concurrence with endometriotic lesion, and highly chemoresistant nature resulting in an extremely poor prognosis. The incidence of CCC has been steadily increasing in Japan. They comprise approximately 20% of all EOC. Understanding the mechanisms of CCC development and elucidating pathogenesis and pathophysiology are intrinsic to prevention and effective therapies for CCC. METHOD OF STUDY This article reviews the English language literature for biology, pathogenesis, and pathophysiological studies on endometriosis-associated EOC. Several data are discussed in the context of endometriosis and CCC biology. RESULTS Recent studies based on genome-wide expression analysis technology have noted specific expression of hepatocyte nuclear factor-1beta (HNF-1beta) in endometriosis and CCC, suggesting that early differentiation into the clear cell lineage takes place in the endometriosis. The HNF-1beta-dependent pathway of CCC will be discussed, which are providing new insights into regulation of apoptosis and glycogen synthesis and resistance of CCC to anticancer agents. CONCLUSIONS This review summarizes recent advances in the HNF-1beta and its target genes; the potential challenges to the understanding of carcinogenesis, pathogenesis, and pathophysiology of CCC; and a possible novel model is proposed.

Abstract
Epithelial ovarian cancer (EOC) is the leading cause of death in women with gynecological malignancies. Among EOC, clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC) differ from the other histological types with respect to their clinical characteristics and carcinogenesis. Both tumor types are often associated with endometriosis. EAC is recently reported to be characterized by K-RAS activation and PTEN dysfunction. However, the molecular changes in CCC remain largely unknown. The aim of this review is to summarize the current knowledge on the molecular mechanisms involved in CCC tumorigenesis. The present article reviews the English language literature for biological, pathogenetic and pathophysiological studies on endometriosis-associated CCC of the ovary. Several recent studies of loss of heterozygosity (LOH), allelic loss, comparative genomic hybridization, mutation, methylation status, microarray gene-expression profiling and proteomics are discussed in the context of CCC biology. Retrograde menstruation or ovarian hemorrhage carries highly pro-oxidant factors, such as heme and iron, into the peritoneal cavity or ovarian endometrioma. A histologically normal ectopic endometrium bears genetic damages caused by iron-dependent oxidative stress. DNA damage or LOH caused by oxidative stress is a critical factor in the carcinogenic process. LOH studies have implicated the involvement of specific chromosomal regions (5q, 6q, 9p, 10q, 11q, 17q and 22q). Furthermore, the PTEN and APC (early event), p53, polo-like kinases, Emi1 and K-RAS (late event) genes may be involved in CCC carcinogenesis. The molecular pathology of CCC is heterogeneous and involves various putative precursor lesions and multiple pathways of development, possibly via genetic alteration by oxidative stress.

Abstract
BACKGROUND Endometriosis may cause symptoms including chronic pelvic pain and infertility, and increases susceptibility to the development of ovarian cancer. Genomic studies have started to delineate the wide array of mediators involved in the development of endometriosis. Understanding the mechanisms of endometriosis development and elucidating its pathogenesis and pathophysiology are intrinsic to prevention and the search for effective therapies. METHOD OF STUDY The present article reviews the English language literature for biological, pathogenetic and pathophysiological studies on endometriosis. Several recent genomic studies are discussed in the context of endometriosis biology. RESULTS Severe hemolysis occurring during the development of endometriosis results in high levels of free heme and iron. These compounds oxidatively modify lipids and proteins, leading to cell and DNA damage, and subsequently fibrosis development. Recent studies based on genome-wide expression analysis technology have noted specific expression of heme/iron-dependent mediators in endometriosis. The heme/iron-dependent signaling pathway of endometriosis, which is providing new insights into the regulation of inflammation, detoxification and survival, is discussed. CONCLUSION Several important endometriosis-specific genes overlap with those known to be regulated by iron. Other genes are involved in oxidative stress. Iron has a significant impact on endometriotic-cell gene expression. This review summarizes recent advances in the heme/iron-mediated signaling and its target genes, outlines the potential challenges to understanding of the pathogenesis and pathophysiology of endometriosis, and proposes a possible novel model.

Abstract
We investigated surgical complications and prognosis of bronchoplasty and bronchoplasty with pulmonary angioplasty (broncho-angioplasty) for lung cancer. Between October 2000 and October 2007, 37 bronchoplastic procedures were done in 572 patients who underwent lung resections for lung cancer. Eleven (29.7%) bronchoplasties were done with pulmonary angioplasty. There was no operative mortality and 1 hospital mortality (2.7%) causing by myocardial infarction. Six of 11 postoperative complications were bronchial complications and 2 additional lung resections were needed. The 5-year survival for all patients was 55.2% and for bronchoplasty was 57.8%. Though the 5-year survival of broncho-angioplasty was not able to calculate at present, the 3-year survival of which was 72.9%. There was no death of patients with adenocarcinoma after introduction of pre-operative assessment by FDG-PET for lymph node metastasis. These data suggest that bronchoplasty and broncho-angioplasty are safe operative procedures and could provide acceptable intermediate survivals with modern multimodality diagnostic and therapeutic tools.

Abstract
Activated neutrophils contribute to the development of preterm delivery. Because of its ability to suppress inflammation, bikunin, a Kunitz-type protease inhibitor, is currently in clinical trials. To investigate the molecular mechanism of this inhibition, we analyzed the effect of bikunin on pro-inflammatory cytokine production and nuclear factor-kappaB (NF-kappaB) activation in mouse neutrophils stimulated by lipopolysaccharide (LPS), an inflammatory inducer. Here, we show that bikunin: (i) blocks LPS-induced secretion of pro-inflammatory cytokines, including TNF-alpha and IL-1beta, in a dose-dependent manner; (ii) has an inhibitory effect on cytokine production at a concentration of 0.2 microM, reaching 65% inhibition at the highest doses of bikunin tested (5 microM); (iii) has the suppressive capacity of ERK1/2 and p38 signaling pathways; and (iv) inhibited sequentially the LPS-induced phosphorylation of IkappaB-alpha, degradation of IkappaB-alpha, and nuclear translocation of NF-kappaB. When the MAPK data are analyzed, a significant decrease in phosphorylation is not seen at 0.2 microM bikunin but is at 1.0 microM dosing. Bikunin can inhibit LPS-induced neutrophil activation and cytokine release, although it is unlikely that it works primarily through the inhibition of MAPK phosphorylation. These data suggest that such effects are important in vivo and play a major contributory role in abrogation of neutrophil-mediated inflammatory responses, such as preterm delivery.

Abstract
Primitive neuroectodermal tumor of the sternum is rare. A 59-year-old woman referred to our department with anterior chest pain and a tumor in the sternum. The patient was diagnosed as primitive neuroectodermal tumor of the sternum by core biopsy of the lesion. She received 2 cycles of preoperative chemotherapy with vincristine, doxorubicin, cyclophosphamide, ifosfamide, etoposide. She underwent a total sternectomy with resection of adjacent bilateral costal cartilages and sternal ends of the clavicles. The skeletal defect of chest wall was reconstructed by polypropylene mesh-resin sandwich. The myocutaneus defect was reconstructed by the pedicled latissimus dorsi myocutaneus flap and the bilateral breast flaps. The postoperative course was uneventful and adjuvant radiotherapy was started 6 weeks after the operation. She died of distant metastases 3 months after the operation, although this patient was free from local recurrence.
