Abstract
The patient is a 76-year-old man. His chief complaint of chest pain led to a diagnosis of pericardial effusion of unknown cause, and pericardial drainage was performed. On the 30th day, chest pain appeared again. Echocardiography revealed a pericardial fluid reaccumulation and a substantial mass in the pericardial space. Surgical drainage was performed to find the cause. A hematoma/mass was present on the epicardium. The pericardial sac was filled with hematoma. The hematoma was removed, but part of the mass infiltrated close to the anterior descending branch of the left coronary artery, and removal of that part was abandoned. The intrapericardial hematoma and epicardium were submitted to pathology leading to the diagnosis of synovial sarcoma. The patient was discharged home 14 days after surgery.

Abstract
Over the years, there has been considerable variation in the bull conception rate (BCR) of Japanese Black cattle; moreover, several Japanese Black bulls with a low BCR of ≤10% have been identified. However, the alleles responsible for the low BCR are not determined yet. Therefore, in this study, we aimed to identify single-nucleotide polymorphisms (SNPs) for predicting low BCR. To this end, the genome of Japanese Black bulls was comprehensively examined by a genome-wide association study with whole-exome sequencing (WES), and the effect of the identified marker regions on BCR was determined. The WES analysis of six sub-fertile bulls with a BCR of ≤10% and 73 normal bulls with a BCR of ≥40% identified a homozygous genotype for low BCR in Bos taurus autosome 5 in the region between 116.2 and 117.9 Mb. The g.116408653G > A SNP in this region had the most significant effect on the BCR (P-value = 1.0 × 10-23), and the GG (55.4 ± 11.2%) and AG (54.4 ± 9.4%) genotypes in the SNP had a higher phenotype than the AA (9.5 ± 6.1%) genotype for the BCR. The mixed model analysis revealed that g.116408653G > A was related to approximately 43% of the total genetic variance. In conclusion, the AA genotype of g.116408653G > A is a useful index for identifying sub-fertile Japanese Black bulls. Some positive and negative effects of SNP on the BCR were presumed to identify the causative mutations, which can help evaluate bull fertility.

Abstract
BACKGROUND Nonadherence diminishes the efficacy of direct oral anticoagulants (DOACs) in patients with nonvalvular atrial fibrillation (NVAF). This report presents the baseline survey results regarding medication adherence among NVAF patients who were treated with once-daily edoxaban or twice-daily apixaban from a randomized control trial of the effect of an educational intervention on DOAC adherence. METHODS We prospectively studied 301 NVAF patients who were treated with edoxaban (n = 175) or apixaban (n = 126) during the 12-week observation period. Adherence was measured with an electronic monitoring system and is expressed as the percentage of days with the correct doses in the measurement period (days). Adherence to DOAC therapy was defined based on the standard threshold (≥80%) or a strict threshold (≥90%). RESULTS Of the 301 patients, 33 had incomplete data or protocol deviations, leaving 268 patients (edoxaban 158 and apixaban 110) for the per-protocol baseline analysis. There was no difference in adherence (threshold ≥80%) between the groups (edoxaban 95% vs apixaban 91%, P = .2), but there was a lower proportion of patients with strict adherence (threshold ≥90%) among apixaban users than among edoxaban users (edoxaban 87% vs apixaban 76%, P = .02). Multivariate analysis showed a negative relationship between apixaban use and an adherence rate ≥90% (odds ratio 0.49, 95% confidence interval [CI]: 0.25-0.94). CONCLUSIONS Our study showed that the proportion of DOAC users with adherence (≥80%) did not differ between the groups, but the proportion of patients with strict adherence (≥90%) was lower among those using apixaban than among those using edoxaban.

Abstract
We report the case of a 33-year-old woman with no history of coronary risk factors or chest pain who experienced intermittent chest pain at rest for several minutes from 2 PM. At 8 AM the next day, chest pain recurred and persisted for about 1 hour. She was transported to our hospital by ambulance, where electrocardiogram showed ST-elevation in the precordial leads, and blood tests showed elevation of cardiac markers. She was diagnosed with ST-elevation myocardial infarction. Because she was a young woman without any risk factors, coronary spastic angina was suspected. Coronary angiography without intracoronary nitrate administration revealed diffuse 75% stenosis in the proximal right coronary artery (RCA) and diffuse 90% stenosis in the left anterior descending artery (LAD). A coronary spasm provocation test elicited chest pain; coronary angiography showed 99% diffuse stenosis of LAD; and electrocardiogram showed precordial ST-segment elevation. Although intracoronary nitroglycerin injection attenuated the coronary spasm in the RCA and proximal LAD, 90% stenosis and coronary dissection were observed in the midportion of the LAD. When the imaging test that was carried out before the provocation test was reexamined, the dissection was recognized, and there was no clear dissection progress after the test. Intravascular ultrasound showed dissection of the LAD, as did angiography. We treated the patient using medical therapy instead of percutaneous coronary intervention.The patient did not suffer any anginal attack and improved sufficiently to be discharged. She remained free of attacks for about 10 years to the present time, and follow-up is continuing.

Abstract
Background This study aimed to examine the impact of baseline eicosapentaenoic acid (EPA) to arachidonic acid (AA) ratio on clinical outcomes of patients with acute coronary syndrome. Methods and Results In the HIJ‐PROPER (Heart Institute of Japan Proper Level of Lipid Lowering With Pitavastatin and Ezetimibe in Acute Coronary Syndrome) study, 1734 patients with acute coronary syndrome and dyslipidemia were randomly assigned to pitavastatin+ezetimibe therapy or pitavastatin monotherapy. We divided the patients into 2 groups based on EPA/AA ratio on admission (cutoff 0.34 μg/mL as median of baseline EPA/AA ratio) and examined their clinical outcomes. The primary end point comprised all‐cause death, nonfatal myocardial infarction, nonfatal stroke, unstable angina pectoris, or ischemia‐driven revascularization. Percentage reduction of low‐density lipoprotein cholesterol and triglyceride from baseline to follow‐up was similar regardless of baseline EPA/AA ratio. Despite the mean low‐density lipoprotein cholesterol level during follow‐up being similar between the low‐ and high‐EPA/AA groups, the mean triglyceride levels during follow‐up were significantly higher in the low‐ than in the high‐EPA/AA group. After 3 years of follow‐up, the cumulative incidence of the primary end point in patients with low EPA/AA was 27.2% in the pitavastatin+ezetimibe group compared with 36.6% in the pitavastatin‐monotherapy group (hazard ratio 0.69; 95% CI, 0.52‐0.93; P=0.015). However, there was no effect of pitavastatin+ezetimibe therapy on the primary end point in patients with high EPA/AA (hazard ratio 0.92; 95% CI, 0.70‐1.20; P=0.52). Conclusions Among acute coronary syndrome patients who have dyslipidemia and low EPA/AA ratio, adding ezetimibe to statin decreases the risk of cardiovascular events compared with statin monotherapy.

Abstract
Polycystic kidney disease (PKD) is a multiple cystic disease involving both the kidneys. Some studies have reported cases of patients with PKD and concurrent aortic dissection; however, autopsy has been performed in only few of these cases. Here, we present the case of a 62-year-old male patient with PKD who showed generalized vascular degeneration, including aortic dissection. The patient had a family history of autosomal dominant PKD and was brought to our hospital because of cardiopulmonary arrest. He was diagnosed with Stanford type A aortic dissection and died on the same day, despite being under cardiopulmonary resuscitation. Autopsy detected multiple cysts in the kidneys, liver, pancreas, and testes. Moreover, multiple tears in the vascular wall of the splenic artery and superior mesenteric artery, including the aorta, were observed. The case findings indicate that patients with PKD may develop associated generalized vascular disease; however, development of cerebral aneurysms and aortic dissections with PKD is particularly serious. Therefore, suitable screening tests must be developed for the early diagnosis and disease characterization, thus, ensuring that the appropriate treatment is administered to the patients.

Abstract
Aims There are regional differences in the patient characteristics, management, and outcomes of hospitalized patients with heart failure (HF). The aim of this study was to evaluate the clinical characteristics and outcomes of Japanese patients who are hospitalized with HF on the basis of the left ventricular ejection fraction (LVEF) stratum. Methods and results We retrospectively conducted a multicentre cohort study of 1245 hospitalized patients with decompensated HF between 2013 and 2014. Of these patients, 36% had an LVEF < 40% [HF with reduced ejection fraction (HFrEF), median age 72 years, 71% male], 21% had an LVEF 40–49% [HF with mid‐range EF (HFmrEF), 77 years, 56% male], and 43% had an LVEF ≥ 50% [HF with preserved EF (HFpEF), 81 years, 44% male]. The primary outcome was death from any cause, and the secondary outcomes were cardiac death and re‐hospitalization due to worsened HF after hospital discharge. There were high proportions of non‐ischaemic cardiomyopathy (32%) in HFrEF patients, coronary artery disease (44%) in HFmrEF patients, and valvular disease (39%) in HFpEF patients. The frequencies of intravenous diuretic and natriuretic peptide administration during hospitalization were 66% and 30%, respectively. The median hospital stay for the overall population was 19 days, and the length of stay was >7 days for >90% of patients. In‐hospital mortality was 7%, but was not different among the LVEF groups (HFrEF 7%, HFmrEF 6%, and HFpEF 8%). After a median follow‐up of 19 months (range, 3–26 months), 192 (17%) of the 1156 patients who were discharged alive died, and 534 (46%) were re‐hospitalized after hospital discharge. There were no significant differences in mortality after hospital discharge among the three LVEF groups (HFrEF 18%, HFmrEF 16%, and HFpEF 16%). There were no differences in cardiac death or re‐hospitalization due to worsened HF after hospital discharge among the LVEF groups (cardiac death: HFrEF 8%, HFmrEF 7%, and HFpEF 7%; re‐hospitalization due to worsened HF: HFrEF 19%, HFmrEF 16%, and HFpEF 17%). Multivariable‐adjusted analyses showed that the HFmrEF and HFrEF groups, compared with the HFpEF group, were not associated with an increased risk for in‐hospital death or death after hospital discharge. Non‐cardiac causes of death and re‐hospitalization after hospital discharge accounted for 35% and 38%, respectively. Conclusions Our results revealed different clinical characteristics but similar mortality rates in the HFrEF, HFmrEF, and HFpEF groups. The most common cause of death and re‐hospitalization after hospital discharge was HF, but non‐cardiac causes also contributed to their prognosis. Integrated management approaches will be required for HF patients.

Abstract
A 34-year-old primigravida who had undergone thrombectomy for deep venous thrombosis (DVT) in her leg and exhibited low protein S activity, indicating predisposition to thrombosis, developed DVT of the leg. No pulmonary embolism was detected. After anticoagulant therapy with unfractionated heparin was discontinued because of liver dysfunction, danaparoid treatment was administered in hospital. The patient had a normal delivery after 39 weeks' gestation with no recurrence of thrombosis. During her second pregnancy four years later, she gave herself fondaparinux injections. She delivered normally after 38 weeks' gestation without experiencing DVT. Fondaparinux may be a useful anticoagulant for heparin-intolerant pregnant women.

Abstract
Background The purpose of this study was to compare the long-term survival of patients with stage IIIB squamous cell carcinoma of the cervix treated with neoadjuvant intraarterial chemotherapy (IA-NAC) versus those treated with concurrent chemoradiotherapy (CCRT). Methods We retrospectively reviewed the clinical records of 38 patients with stage IIIB squamous cell carcinoma of the cervix admitted between January 1994 and December 1999 who received IA-NAC followed by abdominal radical hysterectomy (ARH) or radiotherapy (RT). IA-NAC consisted of bilateral infusion via the internal iliac artery of cisplatin, bleomycin and pirarubicin for 2-3 courses. A historical control group of 64 patients who underwent primary CCRT from January 2000 to September 2007 was used for comparison. Results In the IA-NAC group, 12 patients (31.6%) with operable tumors underwent ARH, and the remaining 26 patients (68.4%) received RT. The response rates were 86.8% (12 complete response + 21 partial response) for IA-NAC and 98.4% (26 complete response + 37 partial response) for CCRT (P = 0.077), respectively. The 5-year overall survival and disease-free survival rates were 62.4 and 44.5% for IA-NAC and 51.1 and 46.9% for CCRT (P = 0.247 and 0.776), respectively. The 5-year overall survival and disease-free survival rates were 75.0 and 58.3% for the patients receiving IA-NAC followed by ARH, and 55.3 and 37.6% for the patients receiving IA-NAC followed by RT (P = 0.368 and 0.262), respectively. Conclusions In the present study, IA-NAC followed by ARH or RT and primary CCRT showed similar survival rates for stage IIIB squamous cell carcinoma of the cervix.

Abstract
BACKGROUND The effects of the combination of angiotensin II receptor blocker (ARB) plus dihydropyridine calcium channel blockers (DHP-CCBs), which is known as a potent antihypertensive drug regimen, on cardiovascular events remain unclear. OBJECTIVE The purpose of this post hoc subgroup analysis was to compare the incidence of major adverse cardiovascular events (MACE) of patients treated with candesartan and amlodipine with that of those with candesartan and non-amlodipine CCBs in hypertensive patients with coronary artery disease (CAD). METHODS HIJ-CREATE was a multicenter, prospective, randomized, controlled study that compared the effects of candesartan-based with those of non-ARB-based standard therapy on MACE in 2049 hypertensive patients with CAD. In the candesartan group, a total of 335 patients were treated with DHP-CCBs (amlodipine: 170 and non-amlodipine-CCBs: 165) at the baseline. In this sub-analysis, we compared, among the participants allocated to candesartan regimen, the long-term effects of amlodipine and non-amlodipine CCBs that were concomitantly given with ARB, although the choice of CCB was not randomized. RESULTS The median follow-up was 3.9 years. Treatment using amlodipine with candesartan reduced the risk of MACE by 38% (hazard ratio, 0.62; 95% confidence interval, 0.41-0.94, p=0.025), as compared to patients treated with non-amlodipine-CCBs and candesartan. In a multivariate analysis, combination therapy of candesartan with amlodipine was an independent predictor of reduced risk of MACE. CONCLUSIONS The results suggest that the combination of amlodipine and candesartan is more beneficial in reducing MACE in hypertensive patients with CAD compared to non-amlodipine-DHP-CCBs in combination therapy with candesartan. Further investigation in larger-scale prospective randomized studies is required to reach any conclusion as to the superiority of combination therapy of candesartan with amlodipine.

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
The aim of this study was to assess the clinical characteristics and outcome of patients with either primary peritoneal carcinoma (PPC) or ovarian serous carcinoma (OSC) treated with paclitaxel plus carboplatin chemotherapy. We retrospectively identified 22 PPC patients and 55 stage III–IV OSC patients treated between 2002 and 2007. After exploratory laparotomy, all patients received paclitaxel and carboplatin every 3 weeks, with the goal of optimal cytoreduction. There were no statistically significant differences between the PPC and OSC groups with regard to tumor stage, residual tumor after debulking surgery (initial or interval), serum cancer antigen (CA) 125 levels at diagnosis, and completion of first-line chemotherapy. The progression-free survival (PFS) durations were 12.7 months (95% CI, 6.3–18.5) in the patients with PPC and 15.9 months (95% CI, 13.3–18.5) in those with OSC (p = 0.016). However, the median survival durations were 26.5 months (95% CI, 14.6–38.3) in the patients with PPC and 38 months (95% CI, 23.8–53.8) in those with OSC (p = 0.188). Survival was longer for all patients whose CA125 levels normalized to 26 U/ml during and after treatment. Overall survival (OS) of the patients with PPC was similar to that of the patients with OSC, suggesting that management for advanced-stage OSC would be similar to that for PPC. The combination of optimal debulking with paclitaxel plus carboplatin chemotherapy may offer patients the most effective treatment. The CA125 nadir after cytoreductive surgery can be considered a prognostic factor for OS and PFS in patients with PPC.

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
This review summarizes data from recent molecular genetic and epidemiology studies of the generic term 'female pelvic cancer'. The English-language literature was reviewed for genetic, epigenetic, epidemiologic and environmental risk factors. There are well-documented disparities among racial and ethnic groups with respect to epithelial ovarian cancer (EOC) prevalence. In the case of the serous histological subtype, primary EOC, fallopian tube cancer and peritoneal cancer could be regarded as a single disease entity. However, EOC is not a single disease. Comparing the profile of EOC between Japanese and Caucasians, clear cell carcinomas (27.6%) are more common in Japan, possibly with fewer serous adenocarcinomas (40.7%). This may reflect a proportional increase. The Japanese may exhibit a higher proportion of malignant transformation of endometriosis compared to the United States population. Although some part of the molecular genetic pathogenesis has been unveiled, the complete events of molecular genetic epidemiological changes associated with EOC remain to be identified. This review focuses on current knowledge of the genetic and environmental factors affecting the development of EOC, and outlines future challenges in its pathogenesis research.

Abstract
Although metastasis to the bone is common in solid tumors, it seldom occurs in endometrial cancer. A rare case of endometrial carcinoma that presented wth symptoms of bone metastasis in the right ischium and treated successfully by zoledronic acid is described. A 57-year-old woman presented with pain of the right ischium. Computed tomography and magnetic resonance imaging revealed bone metastasis and enlargement of the uterus. Endometrial biopsy confirmed endometrial adenocarcinoma. The patient underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy and biopsy of the ischium. Postoperatively, the patient received six courses of chemotherapy using paclitaxel and carboplatin. However, pain of the right-ischium reappeared 9 months after surgery. The patient was treated with 4 mg of zoledronic acid every 4 weeks. After 4 cycles of treatment, the visual analogue scale regressed from 70 to 10. Zoledronic acid can palliate bone pain caused by a variety of endometrial cancers.

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
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
A 70-year-old man presented with sudden onset of global aphasia and right hemiplegia. Brain MRI revealed occlusion of the left middle cerebral artery. He was diagnosed as having a hyperacute cerebral infarction. Intravenous thrombolytic therapy was started, and the neurological symptoms were resolved after 11 h. Echocardiography showed a mobile mass in the left atrium, suspicious of a myxoma. The tumor was resected and pathologically diagnosed as a myxoma. In this patient, intravenous thrombolytic therapy was effective, and no adverse effects were observed. This suggests that, even with complications of myxoma, thrombolytic therapy can be considered if there are no contraindications.

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
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
OBJECTIVES Among epithelial ovarian cancer (EOC), clear cell carcinomas (CCC) differ from the other histologic types with respect to their clinical characteristics, carcinogenesis and prognosis. The aim of this review is to summarize the current knowledge and future perspective on the new therapeutic targets and treatment strategies for CCC. MATERIALS AND METHODS The present article reviews the English language literature for preclinical and clinical trials and promising molecular targets on CCC of the ovary, based on the gene expression profiling studies. RESULTS Here, we show that (1) the expression of the genes involved in transcription, signaling, cell cycle, adhesion, matrix, proteinase, and detoxification was greatly increased in the CCC carcinogenesis; (2) upregulation of hepatocyte nuclear factor-1beta (HNF-1beta) and Polo-like kinase (PLK)-Early mitotic inhibitor-1 (Emi1) as well as their downstream targets are specifically found in most CCC. The promising molecular targeting approach will emerge in the context of HNF-1beta and PLK-Emi1 biology; and 3) several significant common pathways observed in CCC of the ovary overlap the datasets identified in CCC of the kidney. To improve the outcome in CCC therapy, we must learn various adaptive treatment strategies for renal CCC, although it is not supported by any preliminary clinical data. CONCLUSION The inhibitors that target HNF-1beta and PLK-Emi1 and their downstream signaling molecules would be evaluated. In addition, the therapy currently used in renal CCC should be considered as an alternative for the present treatments or an attractive therapeutic option for ovarian CCC. The challenges accompanying the recent advance are described in this review article.

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:Epithelial ovarian cancer (EOC) is the commonest cause of gynecological cancer-related mortality. Although the prognosis for patients with advanced cancer is poor, there is a wide range of outcomes for individual patients.Objective:The aim of this study was to review molecular factors predictive of poor prognosis of women with EOC by reviewing microarray research identifying gene expression profiles.Methods:A systematic search was performed in the electronic databases PubMed and ScienceDirect up to July 2008, combining the keywords "genome-wide," "microarray," "epithelial ovarian cancer" "prognosis," and "epithelial-mesenchymal transition" with specific expression profiles of genes.Results:Many genes that participated in cell signaling, growth factors, transcription factors, proteinases, metabolism, cell adhesion, extracellular matrix component, cell proliferation, and anti-apoptosis were overexpressed in patients with poor prognosis. Several important prognosis-related genes overlap with those known to be regulated by epithelial-mesenchymal transition (EMT). This signaling pathway of EMT (E-cadherin, β-catenin, receptor tyrosine kinases, NF-κB, TGF-β, or Wnt signalings) will be discussed, as it provides new insights into a new treatment strategy.Conclusions:This review summarizes recent advances in prognosis-related molecular biology. Collectively, molecular changes possibly through EMT are considered to be a major contributor to the poor prognosis of EOC.

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
OBJECTIVE The purpose of this study was to describe the clinicopathologic features of malignant transformation in patients with ovarian endometrioma, their treatment and outcome in the Kinki region, Japan. PATIENTS AND METHODS Patients meeting Sampson and Scott's criteria for cancer associated with endometriosis were identified by chart review and pathology reports. This retrospective survey describes 18 women with a history of ovarian endometrioma. These cases were followed as benign ovarian endometrioma before malignant transformation on the basis of imaging findings by gynecologic oncologists or radiologists. RESULTS Mean age at presentation of malignant transformation was 45.2 years (range, 36-66 years), and 78% (n=14) were premenopausal women. The pattern of spread was local in 16 (89%), regional in 2 (11%) and distant in 0 (0%). There was a common left-sided predominance. Characteristic histologic findings were 61% clear cell carcinoma. Endometriosis-associated malignancies have a favorable prognosis. The patients showed long latency intervals before developing ovarian cancer (mean, 4.5 years; range, 1-16 years). Among them, subjects (n=10) whose ages are more than 45 years old had shorter latency intervals (mean, 1 year; range, 1-3 years), compared with those (n=8) aged less than 45 years old (mean, 8.4 years; range, 3-16 years). CONCLUSION Ovarian endometrioma could be viewed as a neoplastic process, particularly in perimenopausal women.

Abstract
The detection of an ovarian mass during pregnancy is often a diagnostic challenge. We describe 2 cases of ovarian endometrioma during pregnancy with marked mural nodules on the cyst wall. The sonographic and MR imaging findings mimicked ovarian cancer. Surgical intervention may still be inevitable to exclude the possibility of malignancy.

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
A giant abdominal tumor can exert a mass effect on surrounding structures. We report here a 34-year-old single female who presented with an increased abdominal girth and was subsequently found to have a giant abdominal mass. Large volume aspiration (85 L) at a slow rate (1 L/min) was initially performed before surgical resection to prevent the development of severe clinical hypotension after large volume aspiration. The patient underwent left salpingo-oophorectomy. Histology revealed a serous cystadenoma of the ovary. Systemic hemodynamics were sequentially measured during the perioperative period. The patient is now well.

Abstract
OBJECTIVE We performed a detailed molecular analysis of bikunin-mediated anti-inflammation (suppressive effect of cytokine release, MAP kinase activation, and nuclear translocation of NF-kB) using a truncated form of bikunin. MATERIALS AND METHODS We obtained bikunin derivatives that contained O-glycoside-linked N-terminal glycopeptide (Bik-m1), N-glycoside-linked C-terminal tandem Kunitz domains (Bik-m2), bikunin lacking O-glycoside (Bik-c), asialo bikunin (Bik-a), bikunin lacking N-glycoside (Bik-n), and purified C-terminal Kunitz domain II (kII) of bikunin (HI-8). Enzyme-linked immunosorbent assay and Western blot were carried out to measure secreted TNF-alpha and MAP kinase activation. RESULTS We examined the TNF-alpha secretion in control and lipopolysaccharide (LPS)-treated neutrophils and did not see any changes of its protein levels in the cells pretreated with Bik-m1, Bik-m2, Bik-c, or HI-8. In all of the derivatives tested, only the derivatives that lacked N-glycoside side chain showed a significant suppression of TNF-alpha secretion by LPS. Only a small (21 amino acids) deletion of the N-terminal portion of bikunin (which corresponds to Bik-m2) abolished its suppressing activity of TNF-alpha secretion, thus suggesting that the N-terminal 21 amino acids play a critical role in anti-inflammation. Bik-m1 alone failed to show anti-inflammatory response. Bikunin failed to inhibit ionomycin-induced phosphorylation of MAP kinases. CONCLUSION These data allow us to conclude that the cytokine expression was inhibited only by the O-glycoside-linked core protein without the N-glycoside side chain. Our results also suggest a possible role of bikunin for receptor-dependent MAP kinase activation.

Abstract
Cyclooxygenase-2 (COX-2) has been implicated in the promotion of carcinogenesis. Although the role of COX-2 in endometrial cancer remains unclear, recent experiments suggest that COX-2 antagonizes cell apoptosis, increases the invasiveness of malignant cells, and promotes angiogenesis. Hepatocyte growth factor (HGF) is a mesenchymal-derived cytokine and the interaction between HGF and its tyrosine kinase receptor, c-Met proto-oncogene, is associated with tumor progression and metastasis. To investigate the molecular mechanism of HGF-induced anoikis resistance, we analyzed the signal transduction and COX-2 expression in endometrial cancer cells. Here, we show i) the expression of COX-2 protein significantly increased in a dose-dependent manner after HGF stimulation in endometrial cancer cell lines (HEC-IB and RL95-2), reaching 200-270% stimulation at the highest doses of HGF tested (40 ng/ml); ii) flow cytometry and TUNEL analyses revealed that HGF significantly inhibited anoikis of RL95-2 cells; iii) phosphatidylinositol 3-kinase (PI3K) inhibitor (LY294002), but not mitogen-activated protein kinase/ERK kinase (MEK) inhibitor (PD98059), specifically blocked HGF-mediated anoikis resistance in RL95-2 cells; and iv) COX-2 inhibitor, Meloxicam, abrogated HGF-mediated anoikis resistance. Our data suggest that HGF induces anoikis resistance in endometrial cancer cells possibly through PI3K/Akt pathway-dependent up-regulation of COX-2 expression.

Abstract
OBJECTIVE Our prospective studies in Japan have found an increased ovarian cancer incidence in women with ovarian endometrioma (standardized incidence ratio, 8.95; 95% confidence intervals, 4.12-5.3). The risk increased with increasing age at ovarian endometrioma diagnosis. The goal of this study was to define the risk factor(s) of ovarian cancer development in a Japanese population with ovarian endometrioma. We also analyzed whether the predisposition toward ovarian cancer is limited to endometrioid and clear cell carcinoma. STUDY DESIGN A total of 6398 participants at 212 participating hospitals in Shizuoka, Japan, were enrolled in the Shizuoka Cohort Study on Endometriosis and Ovarian Cancer (SCSEOC) Trial, which had prospective and retrospective components. The follow-up period was up to 17 years (median, 12.8 years). The risks of development of ovarian cancer were assessed in 6398 women with ultrasonographically diagnosed ovarian endometriomas. Cox proportional-hazards regression function was used to estimate impact in terms of risk factors and possible development of ovarian cancer. RESULTS The prospective study demonstrated that 46 (0.72%) of 6398 women developed histologically proven ovarian cancer and were operated upon during follow-up. Clear cell carcinoma (39%) and endometrioid adenocarcinoma (35%) were commonly observed among women with ovarian cancer. By multivariate analysis, tumor size > or =9 cm in diameter and postmenopausal women were independent predictive factors of patients with development of ovarian cancer. CONCLUSIONS Some endometriosis lesions may predispose to clear cell and endometrioid ovarian cancers. Advancing age and the size of endometriomas were independent predictors of development of ovarian cancer among women with ovarian endometrioma.
