Abstract
A 42-year-old Japanese woman with end-stage renal failure due to hypertension presented with a systolic blood pressure of 160-200 mmHg despite treatment with 4 different antihypertensive agents. The plasma aldosterone concentration (PAC) and plasma renin activity (PRA) were elevated. Adrenal vein sampling suggested bilateral excessive aldosterone secretion, whereas adrenocortical scintigraphy showed right-dominant accumulation. Open bilateral nephrectomy and right adrenalectomy improved the systolic blood pressure, PAC, and PRA. A pathological examination revealed zona glomerulosa hyperplasia but not microaldosteronoma. This report shows that bilateral nephrectomy, not unilateral adrenalectomy, is a potentially effective treatment option for resistant hypertension with an elevated renin-angiotensin-aldosterone system in hemodialysis patients.

Abstract
Increases in prey population size can affect the physiology and ecology of upper-trophic level organisms. This phenomenon is known as a bottom-up effect. For example, the increased abundance of prey resources can trigger physiological (internal) changes in predators, such as improvements in nutritional status. However, these physiological aspects of bottom-up effects have not been considered. In this study, we tested the hypothesis that white-spotted charr Salvelinus leucomaenis, a salmonid fish, increases body stores of omega-3 fatty acids, especially docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), by preying upon stocked hatchery-reared masu salmon Oncorhynchus masou fry in streams. The dynamics of fatty acid contents in charr inhabiting salmon-stocked and unstocked streams clearly support this hypothesis: fatty acid contents (DHA, EPA, and total fatty acid) increased after stocking in stocked streams, but not in unstocked streams. In addition, DHA increased with increasing body size of white-spotted charr and vice versa for EPA. The impacts of human activities, such as fish stocking, on freshwater ecosystems are a matter of serious concern for conservation. Future attempts to gain a comprehensive understanding of the impacts of fish stocking should consider not only community ecology but also physiology.

Abstract
The incidence of atrial fibrillation (AF) and risk of cardiovascular events are reportedly higher in patients with primary aldosteronism (PA) than essential hypertension. However, associated factors of comorbid AF and cardiovascular events in PA patients after PA treatment remain unclear. This nationwide registration study included PA patients ≥20 years old. Incident cardiovascular events were observed with a mean follow-up of approximately 3 years. A total of 3654 patients with PA were included at the time of analysis. Prevalence of AF was 2.4%. PA patients with AF were older, more frequently male and had longer duration of hypertension than those without AF. No significant difference in basal plasma and adrenal venous aldosterone concentration, renin activity, potassium concentration, confirmatory tests of PA, laterality or surgery rate were seen between groups. Logistic regression analysis showed age, male sex, cardiothoracic ratio, past history of coronary artery disease and heart failure were independent factors associated with AF. PA patients with AF showed a higher frequency of cardiovascular events than those without AF (P < 0.001). Multivariate Cox analyses demonstrated AF in addition to older age, duration of hypertension, body mass index and chronic kidney disease as independent prognostic factors for cardiovascular events after PA treatment. Incidence of cardiovascular events were significantly lower in PA patients with AF than AF patients from the Fushimi registry during follow-up after adjusting age, sex and systolic blood pressure. Early diagnosis of PA may prevent AF and other cardiovascular events in PA patients by shortening the duration of hypertension and appropriate PA treatment.

Abstract
Diabetes mellitus is a global health problem. Diabetic nephropathy is a common complication of diabetes mellitus and the leading cause of end-stage renal disease. The clinical course, response to therapy, and prognosis of nephropathy are worse in diabetic than in non-diabetic patients. The role of transforming growth factorβ1 in kidney fibrosis is undebatable. This study assessed whether the overexpression of transforming growth factorβ1 is associated with insulin resistance and the rapid progression of transforming growth factorβ1-mediated nephropathy under diabetic conditions. Diabetes mellitus was induced with streptozotocin in wild-type mice and transgenic mice with the kidney-specific overexpression of human transforming growth factorβ1. Mice treated with saline were the controls. Glucose tolerance and kidney fibrosis were evaluated. The blood glucose levels, the values of the homeostasis model assessment for insulin resistance, and the area of kidney fibrosis were significantly increased, and the renal function was significantly impaired in the diabetic transforming growth factorβ1 transgenic mice compared to the non-diabetic transgenic mice, diabetic wild-type mice, and non-diabetic mice. Transforming growth factorβ1 impaired the regulatory effect of insulin on glucose in the hepatocyte and skeletal muscle cell lines. This study shows that transforming growth factorβ1 overexpression is associated with insulin resistance and rapidly progressive kidney fibrosis under diabetic conditions in mice.

Abstract
BACKGROUND Ectopic adrenocorticotropic hormone (ACTH)-secreting neuroendocrine tumors are rare diseases. Patients with ACTH-secreting pancreatic neuroendocrine carcinomas have a poor prognosis. Infections and coagulopathies have been reported as the cause of death. However, detailed clinical descriptions of the morbid complications of ACTH-secreting neuroendocrine carcinomas have not been reported.
CASE SUMMARY A 78-year-old Japanese woman consulted a medical center due to systemic edema and epigastric discomfort. Laboratory analysis revealed hypercortisolemia with increased ACTH secretion without diurnal variation in serum cortisol level. An enhanced computed tomography (CT) scan revealed a 3-cm tumor in the pancreatic head. The cytological material from endoscopic ultrasound-guided fine-needle aspiration was compatible with ACTH-secreting pancreatic neuroendocrine carcinoma. The Ki-67 index was 40%. She was transferred to Mie University Hospital for surgical treatment. The patient was diagnosed with urinary tract infection, cytomegalovirus hepatitis, esophageal candidiasis, pulmonary infiltrates suspicious for Pneumocystis carinii pneumonia, peripheral deep vein thrombosis, pulmonary embolism, and disseminated intravascular coagulation. The multiple organ infections and thromboses responded well to antimicrobial and anticoagulant therapy. Radioisotope studies disclosed a pancreatic tumor and a metastatic lesion in the liver, whereas somatostatin receptor scintigraphy showed negative findings, suggesting the primary and metastatic tumors were poorly differentiated. A CT scan before admission showed no metastatic liver lesion, suggesting that the pancreatic tumor was rapidly progressing. Instead of surgery, antitumor chemotherapy was indicated. The patient was transferred to another hospital to initiate chemotherapy. However, she died four months later due to the rapidly progressive tumor.
CONCLUSION ACTH-secreting pancreatic neuroendocrine neoplasm is a rare disease with a very poor prognosis. The clinical course and acute complications of the tumor remain unreported. Here we report the clinical course of a rapidly progressive case of ACTH-secreting pancreatic neuroendocrine tumor that developed infectious complications due to many types of pathogens in multiple organs, widespread thromboses, pulmonary embolism, and disseminated intravascular coagulation.

Abstract
The leading cause of death worldwide is cancer. Many reports have proved the beneficial effect of mushrooms in cancer. However, the precise mechanism is not completely clear. In the present study, we focused on the medicinal properties of biomolecules released by fairy ring-forming mushrooms. Fairy chemicals generally stimulate or inhibit the growth of surrounding vegetation. In the present study, we evaluated whether fairy chemicals (2-azahypoxanthine, 2-aza-8-oxohypoxanthine, and imidazole-4-carboxamide) exert anticancer activity by decreasing the expression of Axl and immune checkpoint molecules in melanoma cells. We used B16F10 melanoma cell lines and a melanoma xenograft model in the experiments. Treatment of melanoma xenograft with cisplatin combined with imidazole-4-carboxamide significantly decreased the tumor volume compared to untreated mice or mice treated cisplatin alone. In addition, mice treated with cisplatin and imidazole-4-carboxamide showed increased peritumoral infiltration of T cells compared to mice treated with cisplatin alone. In vitro studies showed that all fairy chemicals, including imidazole-4-carboxamide, inhibit the expression of immune checkpoint molecules and Axl compared to controls. Imidazole-4-carboxamide also significantly blocks the cisplatin-induced upregulation of PD-L1. These observations point to the fairy chemical imidazole-4-carboxamide as a promising coadjuvant therapy with cisplatin in patients with cancer.

Abstract
Abstract
Purpose
We aimed to explore the association of blood pressure (BP) classification using the 2017 American College of Cardiology/ American Heart Association Guideline and the prevalence of hypertensive retinopathy using a nationwide epidemiological database.
Methods
This study is a retrospective observational cross-sectional analysis using the health claims database of the JMDC between 2005 and 2020. We analyzed 280,599 participants who did not take anti-hypertensive medications. Each participant was categorized as having normal BP (systolic BP [SBP] <120 mm Hg and diastolic BP [DBP] <80 mm Hg; n=159,524); elevated BP (SBP 120–129 mm Hg and DBP <80 mm Hg; n=35,603); stage 1 hypertension (SBP 130–139 mm Hg or DBP 80–89 mm Hg; n=54,795); or stage 2 hypertension (SBP ≥140 mm Hg or DBP ≥90 mm Hg; n=30,677). Retinal photography at health check-up was classified as normal, grade 1, grade 2, grade 3, or grade 4 according to the Keith-Wagener-Barker system.
Results
Median (interquartile range) age was 46 (40–53) years, and 50.4% were men. Hypertensive retinopathy which was defined as ≥ Keith-Wagener-Barker system grade 1, was observed in 16,836 participants (6.0%). Multivariable logistic regression analysis showed that, compared with normal BP, elevated BP (odds ratio [OR] 1.30, 95% confidence interval [CI] 1.23–1.38), stage 1 hypertension (OR 1.71, 95% CI 1.64–1.79), and stage 2 hypertension (OR 4.10, 95% CI 3.93–4.28) were associated with higher prevalence of hypertensive retinopathy. Even among 92,121 participants without obesity, high waist circumference, diabetes mellitus, dyslipidemia, cigarette smoking, and alcohol drinking, multivariable logistic regression analysis showed that, compared with normal BP, elevated BP (odds ratio 1.34, 95% CI 1.19–1.51), stage 1 hypertension (OR 1.79, 95% CI 1.61–1.98), and stage 2 hypertension (OR 4.42, 95% CI 4.00–4.92) were associated with higher prevalence of hypertensive retinopathy. The association between BP category and hypertensive retinopathy was observed in all subgroups stratified by age or sex.
Conclusion
Our investigation showed that the prevalence of hypertensive retinopathy increased with the blood pressure category, suggesting that atherosclerotic change could start even in elevated BP and stage 1 hypertension.

Abstract
Diabetes mellitus is a global threat to human health. The ultimate cause of diabetes mellitus is insufficient insulin production and secretion associated with reduced pancreatic β-cell mass. Apoptosis is an important and well-recognized mechanism of the progressive loss of functional β-cells. However, there are currently no available antiapoptotic drugs for diabetes mellitus. This study evaluated whether recombinant human thrombomodulin can inhibit β-cell apoptosis and improve glucose intolerance in a diabetes mouse model. A streptozotocin-induced diabetes mouse model was prepared and treated with thrombomodulin or saline three times per week for eight weeks. The glucose tolerance and apoptosis of β-cells were evaluated. Diabetic mice treated with recombinant human thrombomodulin showed significantly improved glucose tolerance, increased insulin secretion, decreased pancreatic islet areas of apoptotic β-cells, and enhanced proportion of regulatory T cells and tolerogenic dendritic cells in the spleen compared to counterpart diseased mice treated with saline. Non-diabetic mice showed no changes. This study shows that recombinant human thrombomodulin, a drug currently used to treat patients with coagulopathy in Japan, ameliorates glucose intolerance by protecting pancreatic islet β-cells from apoptosis and modulating the immune response in diabetic mice. This observation points to recombinant human thrombomodulin as a promising antiapoptotic drug for diabetes mellitus.

Abstract
Introduction Diabetes mellitus is a serious threat to public health worldwide. It causes a substantial economic burden, mental and physical disabilities, poor quality of life, and high mortality. Limonite is formed when iron-rich materials from the underground emerge and oxidized on the ground surface. It is currently used to purify contaminated water, absorption of irritant gases, and improve livestock breeding. Limonite can change the composition of environmental microbial communities. In the present study, we evaluated whether limonite can ameliorate glucose metabolism abnormalities by remodeling the gut microbiome. Methods The investigation was performed using mouse models of streptozotocin-induced diabetes mellitus and high-calorie diet-induced metabolic syndrome. Results Oral limonite supplement was associated with significant body weight recovery, reduced glycemia with improved insulin secretion, increased number of regulatory T cells, and abundant beneficial gut microbial populations in mice with diabetes mellitus compared to control. Similarly, mice with obesity fed with limonite supplements had significantly reduced body weight, insulin resistance, steatohepatitis, and systemic inflammatory response with significant gut microbiome remodeling. Conclusion This study demonstrates that limonite supplement ameliorates abnormal glucose metabolism in diabetes mellitus and obesity. Gut microbiome remodeling, inhibition of inflammatory cytokines, and the host immune response regulation may explain the limonite’s beneficial activity under pathological conditions in vivo.

Abstract
BACKGROUND Fulminant type 1 diabetes mellitus (FT1DM) is a subtype of type 1 diabetes mellitus characterized by an abrupt onset and a rapid and complete functional loss of islet β cells. It is a very rare disease generally associated with ketoacidosis and the absence of circulating pancreatic islet-related autoantibodies. Diabetic ketoacidosis with normal blood glucose levels has been reported during sodium-glucose co-transporter 2 (SGLT2) inhibitor therapy.
CASE SUMMARY The patient was a 43-year-old woman that consulted a medical practitioner for malaise, thirst, and vomiting. Blood analysis showed high blood glucose levels (428 mg/dL), a mild increase of hemoglobin A1c (6.6%), and increased ketone bodies in urine. The patient was diagnosed with type 2 diabetes mellitus. The patient was initially treated with insulin, which was subsequently changed to an oral SGLT2 inhibitor. Antibodies to glutamic acid decarboxylase were negative. Four days after receiving oral SGLT2 inhibitor, she consulted at Mie University Hospital, complaining of fatigue and vomiting. Laboratory analysis revealed diabetic ketoacidosis with almost normal blood glucose levels. The endogenous insulin secretion was markedly low, and the serum levels of islet-related autoantibodies were undetectable. We made the diagnosis of FT1DM with concurrent SGLT2 inhibitor-associated euglycemic diabetic ketoacidosis. The patient's general condition improved after therapy with intravenous insulin and withdrawal of oral medication. She was discharged on day 14 with an indication of multiple daily insulin therapy.
CONCLUSION This patient is a rare case of FT1DM that developed SGLT2 inhibitor-associated diabetic ketoacidosis with almost normal blood glucose levels. This case report underscores the importance of considering the diagnosis of FT1DM in patients with negative circulating autoantibodies and a history of hyperglycemia that subsequently develop euglycemic diabetic ketoacidosis following treatment with a SGLT2 inhibitor.

Abstract
BACKGROUND Hypoglycemia is a frequent complication observed in diabetic patients under treatment. This metabolic complication is associated with an increased mortality rate in diabetic patients. The use of sensor-augmented pump therapy with predictive low glucose management systems has improved blood glucose level control and reduced the incidence of hypoglycemic attacks. However, this therapy may be associated with adverse events. CASE REPORT A 65-year-old Japanese woman with type 1 diabetes mellitus underwent hemodialysis with end-stage renal failure due to diabetic nephropathy. The patient received sensor-augmented pump therapy with the predictive low glucose management system to prevent recurrent severe hypoglycemia. Hypoglycemia was infrequent when the sensor-augmented pump therapy with a predictive low-glucose management system was properly working. However, the patient suddenly died 3 months after starting the treatment. A record of continuous glucose monitoring showed that hypoglycemia occurred before the sudden death of the patient. CONCLUSIONS The current case shows that sudden death associated with severe hypoglycemia may also occur during sensor-augmented pump therapy with a predictive low glucose management system. This case report underscores the need for close follow-up of diabetic patients receiving sensor-augmented pump therapy with the predictive low glucose management system and the critical importance of patient education on diabetes technology in high-risk patients.

Clinical records revealed no imaging evidence of pancreatic tumor at the time of diagnosis. Subsequently, he had developmental disorders and epilepsy caused by recurrent hypoglycemic attacks. The patient's hypoglycemia improved with oral diazoxide. However, he developed necrotizing acute pancreatitis at 28 years of age, thought to be due to diazoxide. Discontinuation of diazoxide caused persistent hypoglycemia, requiring continuous glucose supplementation by tube feeding and total parenteral nutrition. A selective arterial secretagogue injection test revealed diffuse pancreatic hypersecretion of insulin. He underwent subtotal distal (72%) pancreatectomy and splenectomy. There was no intraoperative visible pancreatic tumor. His hypoglycemia improved after the surgical procedure. The histopathological study revealed a high density of islets of Langerhans in the pancreatic body and tail. There were large islets of Langerhans and multiple neuroendocrine cell nests in the whole pancreas. Nests of neuroendocrine cells were also detected in lymph nodes. The pathological diagnosis was grade 1 neuroendocrine tumor (microinsulinomas) with lymph node metastases. This patient is a difficult-to-diagnose case of hyperinsulinemic hypoglycemia surgically treated after developing acute pancreatitis. We believe this is a unique case of microinsulinomas with lymph metastases diagnosed and treated as congenital hyperinsulinemic hypoglycemia for almost 28 years.

Abstract
The early stages of acromegaly are characterized by slow and progressive acral overgrowth without major systemic complications. Failure to diagnose acromegaly at an early stage may have devastating consequences on patient care. The case in the present report was a 44-year-old Japanese man, referred to Kuwana City Medical Center due to severe hyperglycemia detected in a general checkup. The patient had no acromegaly-related complaints. Laboratory data revealed high blood levels of hemoglobin A1c and glucose. Careful physical examination revealed enlargement of extremities and soft tissues. Laboratory investigation indicated a high blood concentration of growth hormone, and magnetic resonance imaging disclosed an enhanced pituitary tumor. The diagnosis was pituitary tumor-associated acromegaly with severe diabetic complications. The pituitary tumor became large and unresectable following 10 years of misdiagnosis. The patient was treated with somatostatin receptor ligands (lanreotide and pasireotide), as well as bromocriptine in Mie University Hospital. The tumor size was reduced following treatment, though it was still unresectable at the time of this report. The case highlights the importance of hyperglycemia and abnormal manifestations of the feet in patients with acromegaly. In addition, these findings highlight the need for a thorough examination of the feet in diabetic patients, and the critical importance of the early diagnosis of acromegaly for preventing the consequences of inappropriate patient care.

Abstract
Kidney fibrosis is the common consequence of chronic kidney diseases that inexorably progresses to end-stage kidney disease with organ failure treatable only with replacement therapy. Since transforming growth factor-β1 is the main player in the pathogenesis of kidney fibrosis, we posed the hypothesis that recombinant thrombomodulin can ameliorate transforming growth factor-β1-mediated progressive kidney fibrosis and failure. To interrogate our hypothesis, we generated a novel glomerulus-specific human transforming growth factor-β1 transgenic mouse to evaluate the therapeutic effect of recombinant thrombomodulin. This transgenic mouse developed progressive glomerular sclerosis and tubulointerstitial fibrosis with kidney failure. Therapy with recombinant thrombomodulin for four weeks significantly inhibited kidney fibrosis and improved organ function compared to untreated transgenic mice. Treatment with recombinant thrombomodulin significantly inhibited apoptosis and mesenchymal differentiation of podocytes by interacting with the G-protein coupled receptor 15 to activate the Akt signaling pathway and to upregulate the expression of anti-apoptotic proteins including survivin. Thus, our study strongly suggests the potential therapeutic efficacy of recombinant thrombomodulin for the treatment of chronic kidney disease and subsequent organ failure.

Abstract
Background and study aims Magnifying endoscopy with narrow-band imaging (M-NBI) is reported to be useful in diagnosing invasion depth of superficial esophageal squamous cell carcinoma (SCC), but accurate diagnosis of deep submucosal invasion (SM2) has remained difficult. However, we discovered that irregularly branched microvessels observed with M-NBI are detected in SM2 cancers with high prevalence. Thus, this retrospective study aimed to investigate the diagnostic performance of irregularly branched microvessels as visualized by M-NBI for predicting SM2 cancers. Patients and methods Patients with superficial esophageal SCC lesions that were endoscopically or surgically resected at our hospital between September 2005 and December 2014 were included. Endoscopic findings by M-NBI of these lesions were presented to an experienced endoscopist who was unaware of the histopathological diagnosis and who then judged whether irregularly branched microvessels were present. Using the invasion depth according to postoperative histopathological diagnosis as the gold standard, we determined the diagnostic performance of the presence of irregularly branched microvessels as an indicator for SM2 cancers. Results A total of 302 superficial esophageal SCC lesions (228 patients) were included in the analysis. When irregularly branched microvessels were used as an indicator of SM2 cancers, the diagnostic accuracy was 94.0 % (95 % confidence interval [CI]: 91.1-96.1 %), sensitivity was 79.4 % (95 % CI: 66.6-88.4 %), specificity was 95.9 % (95 % CI: 94.3-97.0 %), positive predictive value was 71.1 % (95 % CI: 59.6-79.1 %), and negative predictive value was 97.3 % (95% CI: 95.7-98.5 %). Conclusions Irregularly branched microvessels may be a reliable M-NBI indicator for the diagnosis of cancers with deep submucosal invasion.

Abstract
BACKGROUND In this study, survival and cause of death were investigated in patients with Crohn's disease (CD) at a tertiary referral center. METHODS A database was created based on the medical records of 1108 CD patients who had a history of visiting our hospital to investigate background characteristics, cumulative survival rates from diagnosis, causes of death, and the standardized mortality ratio (SMR) for each cause of death. A follow-up questionnaire survey of patients followed up inadequately was also conducted. The cumulative survival rate from diagnosis was determined using the life table method and compared with that of a sex- and age-matched population model from the year 2000. RESULTS The study included 1108 patients whose mean age at diagnosis was 25.6 ± 10.8 years. The mean duration of follow-up was 14.6 ± 9.4 years, and there were 52 deaths. The cumulative survival rate was significantly lower 25 years after the diagnosis of CD (91.7%) than in the standard population model (95.7%). SMRs for both all causes [3.5; 95% confidence interval (CI): 2.7-4.6] and CD-specific causes (36.7; 95% CI 26.1-51.6) were high. Among the CD-specific causes, SMRs were especially high for small intestine and colorectal cancers, gastrointestinal diseases including intestinal failure (IF), perioperative complications, and amyloidosis. CONCLUSION The SMRs for both all causes and CD-specific causes were high in CD patients. CD-specific causes including intestinal cancer, IF, perioperative complications, and amyloidosis showed especially high SMRs.

Abstract
A 47-year-old woman with diabetes treated with high-dose insulin was admitted to Mie University Hospital, Tsu, Japan, for screening of secondary diabetes mellitus and obesity. Laboratory tests and imaging studies were consistent with Cushing's disease (CD). The patient underwent trans-sphenoidal pituitary surgery. The patient exhibited loss of body weight (85.9 to 80.0 kg), improved glycated hemoglobin (HbA1c) (11.2 to 7.8%) and required lower doses of insulin (112 to 46 U/day) 6 months after surgery. The patient's body weight and daily insulin dose remained stable during the following 5 months (6-11 months after surgery). At that point, the patient was administered with canagliflozin, a sodium-glucose cotransporter 2 inhibitor. The patient required lower daily insulin dose without decreasing the dose of postoperative hydrocortisone concurrent to the administration of canagliflozin (100 mg/day). The patient's body weight decreased to 69.5 kg and withdrawal of insulin therapy was possible 8 months after initiation of canagliflozin. Despite withdrawal of insulin therapy, the HbA1c levels remained at <7.0%. Although surgical treatment is the first-choice treatment for CD, obesity-related metabolic disorders including diabetes are frequent in CD patients following surgery. Canagliflozin may be an effective treatment to reduce body weight and improve insulin resistance following surgical treatment of CD.

Abstract
We developed a microwave oscillator and a micro electromechanical systems-based rubidium cell for the miniaturization of atomic clocks. A thin-film bulk acoustic resonator (FBAR) having a resonant frequency of the fundamental mode in the 3.5 GHz band was employed instead of a crystal resonator. It delivers a clock transition frequency of Rb atoms of 3.417 GHz without the need for a complicated frequency multiplication using a phase-locked loop. This topology considerably reduces the system scale and power consumption. For downsizing the atomic clock system toward the chip level as well as mass production, a microfabricated gas cell containing Rb and N2 gases was also developed. These microcomponents were incorporated into an atomic clock test bench, resulting in a clock operation with a short-term frequency instability of 2.1 × 10-11 at 1 s. To the best of our knowledge, this is the first report of a coherent population trapping clock operation using an FBAR-based microwave oscillator as well as a microfabricated gas cell.

Abstract
BACKGROUND Chronic progression of diabetes is associated with decreased pancreatic islet mass due to apoptosis of β-cells. Patients with diabetes have increased circulating matrix metalloproteinase-2 (MMP2); however, the physiological significance has remained elusive. This study tested the hypothesis that MMP2 inhibits cell apoptosis, including islet β-cells. METHODS Samples from diabetic patients and newly developed transgenic mice overexpressing human MMP2 (hMMP2) were harnessed, and diabetes was induced with streptozotocin. RESULTS Circulating hMMP2 was significantly increased in diabetic patients compared to controls and significantly correlated with the serum C-peptide levels. The diabetic hMMP2 transgenic mice showed significant improvements in glycemia, glucose tolerance and insulin secretion compared to diabetic wild type mice. Importantly, the increased hMMP2 levels in mice correlated with significant reduction in islet β-cell apoptosis compared to wild-type counterparts, and an inhibitor of hMMP2 reversed this mitigating activity against diabetes. The increased activation of Akt and BAD induced by hMMP2 in β-cells compared to controls, links this signaling pathway to the anti-apoptotic activity of hMMP2, a property that was reversible by both an hMMP2 inhibitor and antibody against integrin-β3. CONCLUSION Overall, this study demonstrates that increased expression of hMMP2 may attenuate the severity of diabetes by protecting islet β-cells from apoptosis through an integrin-mediated activation of the Akt/BAD pathway.

Abstract
Background/Aims Decreased trough levels of infliximab (TLI) and antibodies to infliximab (ATI) are associated with loss of response (LOR) in Crohn's disease. Two prospective studies were conducted to determine whether TLI or ATI better correlates with LOR (Study 1), and whether TLI could become a predictor of mucosal healing (MH) (Study 2). Methods Study 1 was conducted in 108 patients, including those with LOR and remission to compare ATI and TLI in discriminating the 2 conditions based on receiver operating characteristic (ROC) curve analyses. Study 2 involved 35 patients who were evaluated endoscopically. Results In Study 1, there were no differences between the 2 assays in ROC curve analyses; the TLI cutoff value for LOR was 2.6 µg/mL (sensitivity, 70.9%; specificity, 79.2%), and the ATI cutoff value was 4.9 µg/mL (sensitivity, 65.5%; specificity, 67.9%). The AUROC (area under the ROC curve) of TLI was greater than that of ATI. AUROC was useful for discriminating between the 2 conditions. In Study 2, the TLI was significantly higher in the colonic MH group than in the non-MH group (2.7 µg/mL vs. 0.5 µg/mL, P=0.032). Conclusions TLI is better than ATI for clinically diagnosing LOR, and a correlation was observed between TLI and colonic MH.

Abstract
SummaryThe activity of plasmin plays a critical role in the development of chronic glomerulonephritis. Thrombin-activatable fibrinolysis inhibitor (TAFI) is a potent inhibitor of plasmin generation. We hypothesized thatTAFI is involved in the pathogenesis of glomerulonephritis because it inhibits plasmin generation. To demonstrate this hypothesis, we compared the development of immune complex-mediated glomerulonephritis in wild-type and TAFI-deficient mice. After six weeks of treatment with horse spleen apoferritin and lipoplysaccharide to induce glomerulonephritis, mice deficient in TAFI had significantly better renal function as shown by lower concentrations of albumin in urine and blood urea nitrogen compared to wild-type mice. In addition, the activity of plasmin and matrix metalloproteinases was significantly increased, and mesangial matrix expansion and the deposition of collagen and fibrin in kidney tissues were significantly decreased in TAFI-knockout mice as compared to their wildtype counterparts. Depletion of fibrinogen by batroxobin (Defibrase) treatment led to equalization of the renal function and the amount of collagen deposition in the kidneys of TAFI-knockout and wild-type mice with immune complex-mediated glomerulonephritis. Together these observations suggest that TAFI-mediated inhibition of plasmin generation plays a role in the pathogenesis of glomerulonephritis, and that it may constitute a novel molecular target for the therapy of this disease.

Abstract
BACKGROUND Continuous glucose monitoring (CGM) is reported to be a useful technique, but difficult or inconvenient for some patients and institutions. We are developing a glucose area under the curve (AUC) monitoring system without blood sampling using a minimally invasive interstitial fluid extraction technology (MIET). Here we evaluated the accuracy of interstitial fluid glucose (IG) AUC measured by MIET in patients with diabetes for an extended time interval and the potency of detecting hyperglycemia using CGM data as a reference. METHODS Thirty-eight inpatients with diabetes undergoing CGM were enrolled. MIET comprised a pretreatment step using a plastic microneedle array and glucose accumulation step with a hydrogel patch, which was placed on two sites from 9:00 AM to 5:00 PM or from 10:00 PM to 6:00 AM. IG AUC was calculated by accumulated glucose extracted by hydrogel patches using sodium ion as standard. RESULTS A significant correlation was observed between the predicted AUC by MIET and CGM in daytime (r=0.76) and nighttime (r=0.82). The optimal cutoff for the IG AUC value of MIET to predict hyperglycemia over 200 mg/dL measured by CGM for 8 hours was 1,067.3 mg·hr/dL with 88.2% sensitivity and 81.5% specificity. CONCLUSION We showed that 8-hour IG AUC levels using MIET were valuable in estimating the blood glucose AUC without blood sampling. The results also supported the concept of using this technique for evaluating glucose excursion and for screening hyperglycemia during 8 hours in patients with diabetes at any time of day.

Abstract
The direct measurements of high-frequency electric fields in a plasma bring about significant advances in the physics and engineering of various waves. We have developed an electro-optic sensor system based on the Pockels effect. Since the signal is transmitted through an optical fiber, the system has high tolerance for electromagnetic noises. To demonstrate its applicability to plasma experiments, we report the first result of measurement of the ion-cyclotron wave excited in the RT-1 magnetosphere device. This study compares the results of experimental field measurements with simulation results of electric fields in plasmas.

Abstract
We study the behavior of high-energy positrons emitted from a radioactive source in a magnetospheric dipole field configuration. Because the conservation of the first and second adiabatic invariants is easily destroyed in a strongly inhomogeneous dipole field for high-energy charged particles, the positron orbits are nonintegrable, resulting in chaotic motions. In the geometry of a typical magnetospheric levitated dipole experiment, it is shown that a considerable ratio of positrons from a ^{22}Na source, located at the edge of the confinement region, has chaotic long orbit lengths before annihilation. These particles make multiple toroidal circulations and form a hollow toroidal positron cloud. Experiments with a small ^{22}Na source in the Ring Trap 1 (RT-1) device demonstrated the existence of such long-lived positrons in a dipole field. Such a chaotic behavior of high-energy particles is potentially applicable to the formation of a dense toroidal positron cloud in the strong-field region of the dipole field in future studies.

Abstract
Case A 64‐year‐old Japanese woman with diabetes mellitus was admitted for hypoglycemia. Her diabetes had been under good control with glimepiride, voglibose, exenatide, and metformin for a few years. Although overt proteinuria was observed, the serum creatinine values were within normal range during the routine outpatient follow‐up. Hypoglycemic attack caused by glimepiride and loss of appetite by urinary tract infection were diagnosed. Then, metformin‐associated lactic acidosis with acute renal failure caused by dehydration was detected. Outcome Her condition was improved by continuous veno‐venous hemodiafiltration and hemodialysis, known to be useful to remove metformin. Conclusion We reported a case of metformin‐associated lactic acidosis with hypoglycemia during routine treatment of diabetes that was successfully rescued by early renal replacement therapy.

Abstract
AIM This study used a multicenter questionnaire survey to evaluate the morphology and progression of the initial lesion in cases of colitis-associated colorectal neoplasia (CRN). PATIENTS AND METHODS Endoscopic images of lesions that had been definitively diagnosed as CRN by pathological examination were retrospectively reviewed. RESULTS This resulted in the identification of 54 initial lesions in 49 patients. The 54 initial lesions fell into the following categories: 22 endoscopically visible localized lesions consisting of 18 elevated lesions and 4 depressed lesions, as well as 32 lesions that were not endoscopically visible as localized and consisted of 20 active-phase mucosal lesions and 12 remission-phase mucosal lesions. Nineteen of the lesions eventually became advanced cancers, while 35 lesions eventually became early-stage cancers. The final lesions were 40 elevated lesions, 5 flat or depressed lesions and 9 stenotic lesions. The form of growth of the advanced cancers was progressive stenosis or increased elevation. For approximately 69% of the early-stage cancers, the growth form was increasing elevation or development of elevation. For 73.6% of the advanced cancers, the initial lesion underwent rapid growth and became advanced cancer within 3 years; they accounted for 25.9% of the total cancers. Approximately 40% of the initial lesions of CRN were endoscopically visible as localized lesions, while approximately 60% were judged to be inflammatory mucosal lesions. CONCLUSION It will be necessary to proactively take biopsy inflammatory mucosal lesions in order to discover tumors early and periodic surveillance should be performed with the knowledge that tumors may grow very quickly.

Abstract
Protein S is an anticoagulant factor that also regulates inflammation and cell apoptosis. The effect of protein S on diabetes and its complications is unknown. This study compared the development of diabetes between wild-type and transgenic mice overexpressing human protein S and the development of diabetic glomerulosclerosis between mice treated with and without human protein S and between wild-type and protein S transgenic mice. Mice overexpressing protein S showed significant improvements in blood glucose level, glucose tolerance, insulin sensitivity, and insulin secretion compared with wild-type counterparts. Exogenous protein S improved insulin sensitivity in adipocytes, skeletal muscle, and liver cell lines in db/db mice compared with controls. Significant inhibition of apoptosis with increased expression of BIRC3 and Bcl-2 and enhanced activation of Akt/PKB was induced by protein S in islet β-cells compared with controls. Diabetic wild-type mice treated with protein S and diabetic protein S transgenic mice developed significantly less severe diabetic glomerulosclerosis than controls. Patients with type 2 diabetes had significantly lower circulating free protein S than healthy control subjects. This study shows that protein S attenuates diabetes by inhibiting apoptosis of β-cells and the development of diabetic nephropathy.

Abstract
In Japan, the incidence of type 2 diabetes mellitus (T2DM) is increasing for several reasons, including increased consumption of sugar-sweetened beverages (SSBs). However, whether SSBs cause T2DM by excess of energy production resulting in obesity remains unclear. Therefore, the present study was designed to evaluate the effects of SSB intake on the development of T2DM in subjects with impaired glucose tolerance (IGT). Ninety-three subjects (30 males and 63 females) with IGT aged 40-69 y and residing in the Mihama district (southern Mie Prefecture, Japan) were included in the study. The mean observational period was 3.6 y. All subjects underwent the 75-g oral glucose tolerance test (OGTT) and completed a lifestyle questionnaire survey related to SSB intake. OGTT results and SSB intake were evaluated before and after the observational period. In addition, the correlation between SSB intake and development of T2DM was investigated. Of the 93 subjects, 20 (21.5%) developed T2DM (T2DM group) and demonstrated a significantly high SSB intake compared with the group that did not develop the disease (non-T2DM group). The odds ratio for the incidence of T2DM based on SSB intake was 3.26 (95% confidence interval, 1.17-9.06). The body mass index (BMI; kg/m(2)) and the homeostasis model assessment for insulin resistance (HOMA-R) values was significantly higher in the T2DM group than in the non-T2DM group, while the insulinogenic indices were significantly lower in the former than in the latter group. The sum of insulin secretion levels during OGTT was not significantly different between groups. SSB intake correlated with the predisposition for developing T2DM, possibly by influencing body weight, insulin resistance, and the ability of the pancreatic beta cells to effectively compensate for the insulin resistance.

Abstract
Objective We investigated the relationship of the waist circumference (WC) and body fat weight (BF) with insulin resistance in subjects with normal body mass index (BMI) and normal glucose tolerance (NGT) during a routine medical check-up. Methods We categorized 167 male subjects in three groups as follows: a group with normal BMI but high WC (normal-BMI/high-WC group; 22≤BMI<25 kg/m(2), waist ≥85 cm; n=31), a group with normal BMI and normal WC (normal-BMI/normal-WC group, waist <85 cm; n=68), and a group with low normal BMI and normal WC (low normal-BMI/normal-WC group; 18.5≤BMI<22 kg/m(2) and waist<85 cm; n=68). We measured the plasma glucose and serum insulin levels before glucose loading and after 30 and 120 minutes and calculated several indexes of insulin secretion and sensitivity. Results Subjects from the normal-BMI/high-WC group showed significantly decreased Matsuda index and increased homeostasis model assessment for insulin resistance (HOMA-IR) compared with normal-BMI/normal-WC group. Univariate regression analyses showed significant correlation of HOMA-IR with WC (r=0.39) and BF (r=0.37). Matsuda index was significantly correlated with WC (r=-0.39) and BF (r=-0.47). The multiple regression analysis showed that the BF is significantly correlated with HOMA-IR (p<0.05) and Masuda index (p<0.005) among the clinical variables and with HOMA-IR (p<0.05) and Masuda index (p<0.0001) among the anthropometric variables but not with WC in either analysis. Conclusion Decreased Matsuda index and increased HOMA-IR were observed in subjects from the normal-BMI/high-WC group. Multivariate analysis showed that BF is associated with decreased Matsuda index and increased HOMA-IR and that WC is not associated with either factors.

Abstract
BACKGROUND AND AIMS Intestinal complications of stenosis or fistula may occur during the course of Crohn's disease (CD), and surgery is performed in a fair number of patients. The risk factors for initial surgery in a Japanese hospital-based cohort of CD patients were evaluated. METHODS This study was a single-center, retrospective, cohort study. The subjects were 520 patients who underwent inpatient and outpatient treatment at our hospital, had a definitive diagnosis of CD, and no previous surgery. Three parameters were investigated: (i) cumulative incidence of stenosis and fistula; (ii) cumulative rate of initial surgery for each disease type; and (iii) risk factors at diagnosis for initial surgery. RESULTS (i) Stenosis and fistula increased with time, with stenosis or fistula appearing in about half of the patients after 5 years. (ii) The cumulative rate of initial surgery was about 50% after 10 years. (iii) The patient factors at diagnosis of current smoker, upper gastrointestinal disease, stricturing, penetrating, moderate to severe stenosis of the jejunum, moderate to severe stenosis of the ileum, and moderate to severe stenosis of the terminal ileum were risk factors for initial surgery. CONCLUSIONS Stenosis or fistula appeared in about half of the patients after 5 years from diagnosis. When upper gastrointestinal disease or complicated small intestinal lesions are seen at the time of diagnosis, the cumulative rate of initial surgery is significantly higher.

Abstract
OBJECTIVE To evaluate the confidence ratings of diagnoses of simulated lesions other than lung cancer on low-dose screening CT with hybrid iterative reconstruction (IR). METHODS Simulated lesions (emphysema, mediastinal masses and interstitial pneumonia) in a chest phantom were scanned by a 320-row area detector CT. The scans were performed by 64-row and 160-row helical scans at various dose levels and were reconstructed by filtered back projection (FBP) and IR. Emphysema, honeycombing and reticular opacity were visually scored on a four-point scale by six thoracic radiologists. The ground-glass opacity as a percentage of total lung volume (%GGO), CT value and contrast-to-noise ratio (CNR) of mediastinal masses were calculated. These scores and values were compared between FBP and IR. Wilcoxon's signed-rank test was used (p < 0.05). Interobserver agreements were evaluated by κ statistics. RESULTS There were no significant differences in visual assessment. Interobserver agreement was almost perfect. CT values were almost equivalent between FBP and IR, whereas CNR with IR was significantly higher than that with FBP. %GGO significantly increased at low-dose levels with FBP; however, IR suppressed the elevation. CONCLUSION The confidence ratings of diagnoses of simulated lesions other than lung cancer on low-dose CT screening were not degraded with hybrid IR compared with FBP. ADVANCES IN KNOWLEDGE Hybrid IR did not degrade the confidence ratings of diagnoses on visual assessment and differential diagnoses based on CT value of mediastinal masses, and it showed the advantage of higher GGO conspicuity at low-dose level. Radiologists can analyse images of hybrid IR alone on low-dose CT screening for lung cancer.
