Abstract
An 82-year-old man with Philadelphia chromosome-negative acute lymphoblastic leukemia (ALL) complicated by hepatocarcinoma was presented. Remission induction therapy of hyper-CVAD with half dose reduction achieved hematological complete remission (CR), but accompanied with elevated alanine aminotransferase and hyperbilirubinemia. The patient was thought intolerable for hyper-CVAD with half dose reduction due to liver toxicity, and treatment was switched to blinatumomab. Hematological CR was sustained after nine cycles of blinatumomab without exacerbation of liver dysfunction. After five courses of blinatumomab, hepatocarcinoma was treated successfully by trans-arterial chemoembolization. Two years after the diagnosis of ALL, the patient was alive in CR status of ALL.

Abstract
Patient 1 was a 70-year-old woman with refractory diffuse large B-cell lymphoma who received allogeneic peripheral blood stem cell transplantation from an HLA-haploidentical related donor. Upper back pain appeared on day63, and Th8-Th9 pyogenic spondylitis was diagnosed based on magnetic resonance imaging (MRI). Blood culture on day14 identified Corynebacterium striatum as the causative bacteria of blood stream infection (BSI). The pyogenic spondylitis resolved after treatment with daptomycin for 2 months. Patient 2 was a 65-year-old man with relapsed angioimmunoblastic T-cell lymphoma who received bone marrow transplantation from an HLA-DR single-antigen-mismatched unrelated donor. Lower back pain appeared on day30, and L4-L5 pyogenic spondylitis was diagnosed based on MRI. Blood culture was negative. Daptomycin and clindamycin were selected for treatment based on the drug susceptibility of bacteria that had caused pre-engraftment BSI (Escherichia coli on day3 and Corynebacterium striatum on day9), and the pyogenic spondylitis resolved after 6 months of this treatment. Pyogenic spondylitis should be considered in the differential diagnosis of back pain accompanied by BSI before engraftment in allogeneic hematopoietic stem cell transplant recipients.

Abstract
A 66-year-old man was diagnosed with symptomatic IgG-λ multiple myeloma based on the presence of anemia, thrombocytopenia, renal dysfunction, and a tumor on the right sixth rib. Bone marrow aspiration yielded a dry tap and biopsy revealed myelofibrosis grade 2. Partial response was achieved with Bd (bortezomib and dexamethasone) and VRd (bortezomib, lenalidomide, and dexamethasone). The patient received autologous stem cell transplantation, but the myeloma relapsed 3 months later, and liver tumors developed as well. DKd (daratumumab, carfilzomib, and dexamethasone) was administered, but the patient died due to disease progression. Autopsy revealed multiple extramedullary lesions in the liver, spleen, gallbladder, adrenal glands, kidneys, and multiple lymph nodes, as well as ascites.

Abstract
Euglycemic diabetic ketoacidosis (eDKA) has emerged as an adverse event associated with sodium-glucose transporter-2 inhibitors (SGLT2i). We present two consecutive cases of SGLT2i-induced eDKA, both manifested as life-threatening coronary vasospastic angina (VSA). Case 1: A 64-year-old male overweight patient with type 2 diabetes (BMI 28.2 kg/m2), treated with dapagliflozin 5 mg daily for 6 months and a restricted diet for 2 months, experienced loss of consciousness following severe chest pain while driving, resulting in a traffic accident: plasma glucose, 163 mg/dL; urine ketones, (+++); bicarbonate (HCO3-), 13.2 mmol/L; and total ketone body, 1539 µmol/L. Coronary angiography (CAG) performed on day 5 revealed diffusely spastic coronary arteries with 90% stenosis in the right coronary artery, leading to the diagnosis of VSA in the presence of coronary atherosclerosis. Case 2: A 63-year-old male patient with type 2 diabetes (BMI 22.2 kg/m2) experienced severe chest discomfort and faintness following 2 months of chest pain while on dapagliflozin 10 mg daily for 1 year: plasma glucose, 112 mg/dL; urine ketones, (+++); HCO3-, 15.3 mmol/L; and total ketone body, 10,883 µmol/L. CAG performed on day 10 revealed no organic stenosis but diffusely spastic coronary arteries in response to coronary ergonovine infusion, confirming the diagnosis of VSA. SGLT2i has the potential to inhibit acetylcholine and butyrylcholine esterase activities, leading to reduced scavenging of acetylcholine and possible induction of coronary vasospasm. These cases highlight the association between life-threatening VSA and SGLT2i-induced eDKA.

Abstract
A 72-year-old woman presented with generalized lymphadenopathies and plasmacytosis accompanied by polyclonal hypergammopathy. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) showed FDG accumulation in the systemic lymph nodes, spleen, and multiple bones. Human immunodeficiency virus antibody was negative. Lymph node histologic findings showed a monotonous population of plasma cells with a starry-sky appearance. The cells were positive for CD19, λ, and Epstein-Barr virus-encoded RNA, and negative for CD20 and CD56. The MIB-1 index was 80%. A diagnosis of plasmablastic lymphoma with plasmacytosis and polyclonal hypergammopathy was made, and complete metabolic response was achieved after six cycles of dose-adjusted-EPOCH therapy (etoposide, prednisolone, vincristine, cyclophosphamide, and doxorubicin).

Abstract
A 69-year-old woman was diagnosed with acute myeloid leukemia (AML) with an FMS-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) mutation. Complete remission (CR) was achieved after induction therapy, but AML resulted in a hematological relapse two months after the consolidation chemotherapy. Relapse was accompanied by multiple skin lesions that demonstrated leukemic cell infiltration as well as a drooping right eyelid with extroversion of the eye due to right oculomotor palsy. Gilteritinib was started as salvage therapy, and bone marrow blasts decreased to 0.8% after one month. Two months later, the eye symptoms improved, and the patient underwent cord blood transplantation (CBT). The skin lesions disappeared after the conditioning regimen, and the patient achieved CR status with complete donor chimerism at day 28. Gilteritinib was restarted as posttransplant maintenance therapy on day 53 of CBT. No adverse events other than mild hepatotoxicity were observed, and the patient was alive and in CR status, while continuing gilteritinib at one year and seven months after CBT. Bridging and posttransplant maintenance therapy with gilteritinib may be a promising therapeutic option for relapsed AML with the FLT3-ITD mutation in elderly patients.

Abstract
A large-scale sluice gate, which was built in southwest Japan as a national project to reclaim and desalinate lagoon water in 1974, was removed between 2005 and 2009. To examine the impact of this removal on both Nakaumi Lagoon and the nearby coastal waters, we analyzed the foraminiferal assemblages of a coastal sediment core and of samples obtained during 10 years of lagoon monitoring (2001-2010). Detailed 210Pb(ex) dating of the sediment core revealed an increased sediment accumulation rate in the coastal waters, implying that discharge of fine-grained materials, including organic matter, was facilitated by removal of the sluice gate. The observed increase in agglutinated foraminifera and decrease in calcareous species was related to the sediment accumulation rate, and these changes occurred close to 2005, when sluice-gate removal began. In Nakaumi Lagoon, the sporadic presence of the coastal species Quinqueloculina seminula within the 6-m water column and the decline in the lagoon-adapted Ammonia "beccarii" have occurred since 2005. The removal of the sluice gate, plus the sea-level rise, allowed greater seawater inflow and stabilized the monthly deep-water salinity fluctuations in Nakaumi Lagoon.

Abstract
A 54-year-old male patient, who presented with multiple lymphadenopathies, bilateral leg edema, and oscheohydrocele, was diagnosed with diffuse large B-cell lymphoma (DLBCL) stage IVB. His lymphadenopathies disappeared after six courses of R-CHOP therapy, which consist of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone); however, right hypopyon and partly remaining testicular soft tissue masses with fluorodeoxyglucose accumulation were observed. Lymphoma cell infiltration was observed in the aqueous humor of the right anterior chamber and testis, which indicates DLBCL progression. Hypopyon disappeared after the first course of intrathecal chemotherapy combined with R-HDMA therapy, which consists of rituximab and high-dose methotrexate/cytarabine, but recurred in the third course. The patient then underwent busulfan and thiotepa (BuTT) therapy followed by autologous peripheral blood stem cell transplantation (auto-PBSCT) after four courses of R-HDMA therapy. Hypopyon promptly disappeared after BuTT therapy and no hypopyon recurrence was observed 9 months after auto-PBSCT. Therefore, BuTT therapy is effective for hypopyon associated with refractory DLBCL.

Abstract
A 28-year-old male patient presented with multiple lymphadenopathies and extranodal masses. He was diagnosed with stage IVB ALK-positive anaplastic large cell lymphoma after the right axillary lymph node biopsy. A partial metabolic response with fluorodeoxyglucose accumulation was observed in the residual disease of the upper left hilar lymph node after eight courses of brentuximab vedotin, cyclophosphamide, adriamycin, and prednisolone. We started alectinib at 600 mg daily, which achieved a complete metabolic response (CMR) after three months. The CMR was maintained and alectinib was continuously administered without adverse events at the last follow up. Alectinib showed high efficacy and tolerability, though the optimal period and long-term adverse effects of administration remain unclear. Therefore, further studies are necessary.

The radiological impact for human and aquatic biota as a result of a planned release of contaminated water stored in tanks near the Fukushima Dai-ichi Nuclear Power Plant to the Pacific Ocean is assessed. The total activity for 10 dominant radionuclides (3H, 14C, 60Co, 90Sr, 99Tc, 106Ru, 125Sb, 129I, 134Cs, 137Cs) in tanks is estimated. The compartment model POSEIDON-R is applied to compute the concentration of activity for each radionuclide in water, bottom sediments, and biota, and corresponding doses to marine organisms and humans from seafood consumption. Predicted concentrations of activity in marine products in future will not exceed food safety limits in Japan. The computed maximum committed effective dose to humans is less than 1 μSv per year with the highest contribution from 129I and 14C. Maximum absorbed doses to non-human biota are in the order of 0.05 to 20 μGy per year, meaning that no deleterious effects are expected.

Abstract
We report the case of a 79-year-old man with chronic lymphocytic leukemia (CLL) with IgM-kappa type monoclonal gammopathy according to immunophenotypes and a negative result for MYD88 L265P mutation of leukemic cells. Abnormal lymphocytes and IgM increased under observation, and he experienced paresthesia. The diagnosis of IgM-type M protein associated peripheral neuropathy was confirmed by nerve conduction test, and negativity of myelin-associated glycoprotein and glycolipid antibodies. He was placed on intravenous immunoglobulin (IVIg) in combination with ibrutinib. His symptoms dramatically subsided and did not recur. Treatment with IVIg and ibrutinib may be useful for the rare complication of peripheral neuropathy with CLL.

Abstract
Two cases of human herpesvirus 8 (HHV8)-negative effusion-based lymphoma (EBL) involving unilateral pleural effusion that regressed only after drainage are reported. Cases 1 and 2 were 91- and 81-year-old men with right and left pleural effusion, respectively. No chemotherapy was administered to either patient because of their advanced age and the presence of cardiac comorbidities. They completely recovered after effusion drainage alone without relapse till the last observation. Thus, this study suggests that some patients with HHV8-negative EBL can be safely managed with effusion drainage alone.

Abstract
BACKGROUND Little is known about the kinetics and clinical significance of saliva human herpesvirus-6 (HHV-6) DNA after hematopoietic stem cell transplantation (HSCT). METHODS In this observational study, we quantified HHV-6 DNA in serially collected plasma and saliva from allogeneic HSCT recipients. Associations between the status of salivary HHV-6 DNA and the development of HHV-6 encephalitis, depression, and oral mucosal graft-versus-host disease (GVHD) were retrospectively analyzed. RESULTS A total of 787 plasma and 434 saliva samples were collected from 56 patients. The cumulative incidence of HHV-6 DNA in plasma and saliva at 60 days after transplantation was 51.8% and 83.9%, respectively. The peak level of salivary HHV-6 DNA was significantly higher in patients who displayed plasma HHV-6 DNA than in those who did not (median, 51,584 copies/mL vs 587 copies/mL; P < .0001). Salivary HHV-6 DNA levels increased after positive plasma HHV-6 DNA was detected and remained high during observation period. Despite the frequent occurrence of positive salivary HHV-6 DNA, no patient developed depression. Positivity of salivary HHV-6 DNA was not significantly associated with the development of HHV-6 encephalitis (P = 1.00, Fisher's exact test) or oral mucosal GVHD (P = .71, Grey's test). No significant relationship between salivary HHV-6 DNA and these diseases was found even when comparing higher HHV-6 DNA loads in saliva. CONCLUSION Salivary HHV-6 DNA levels increased after HHV-6 DNA was detected in the blood. However, no epidemiological evidence was shown to support a role of salivary HHV-6 in the development of HHV-6 encephalitis, depression, and oral mucosal GVHD.

Abstract
To investigate the dispersion of Fukushima Dai-ichi Nuclear Power Plant (FDNPP)-derived radiocesium in the Sea of Japan and western Pacific coastal region and determine the sources of radiocesium in these areas, we examined the temporal and spatial variations of 134Cs and 137Cs concentrations (activities) during 2011-2016 in seawaters around the western Japanese Archipelago, particularly in the Sea of Japan. In May 2013, the surface concentration of 134Cs was ∼0.5 mBq/L (decay-corrected to March 11, 2011), and that of 137Cs exceeded the pre-accident level in this study area, where the effects of radiocesium depositions just after the FDNPP accident disappeared in surface waters in October 2011. Subsequently, radiocesium concentrations gradually increased during 2013-2016 (∼0.5-1 mBq/L for 134Cs), exhibiting approximately homogeneous distributions in each year. The temporal and spatial variations of 134Cs and 137Cs concentrations indicated that FDNPP-derived radiocesium around the western Japanese Archipelago, including the Sea of Japan, has been supported by the Kuroshio Current and its branch, Tsushima Warm Current, during 2013-2016. However, in the Sea of Japan, the penetration of 134Cs was limited to depths of less than ∼200 m during three years following the re-delivery of FDNPP-derived radiocesium.

Abstract
Seven aneurysms in elderly patients (average 78 year-old) were treated by intra-aneurysmal coil embolization. The 19 gage elastic needle or 4.0Fr. sheath introducer was placed into the carotid artery, and 3.0Fr. microcatheter was advanced into the aneurysm. An operative difficulty to approach to the aneurysm due to arteriosclerosis was ameliorated by this method. Mobility related to this procedure was a local hematoma at the puncture site in one case.

Abstract
Philadelphia chromosome positive (Ph+) mixed phenotype acute leukemia (MPAL) is a rare type of acute leukemia having both myeloid and lymphoid features for which no optimal treatment has yet been established. We herein describe two elderly Ph+MPAL patients who achieved molecular remission without any serious adverse events by treatment with dasatinib and prednisolone. Although dasatinib induction therapy combined with prednisolone is known to be a highly effective treatment for Ph+ acute lymphoblastic leukemia, its efficacy for Ph+MPAL has not been shown. The clinical courses of the present cases suggest that combination therapy with dasatinib and prednisolone is a safe and effective therapeutic modality in elderly Ph+MPAL patients.

Abstract
Toxoplasmic encephalitis is a rare infectious complication in patients with hematological malignancy except for allogeneic hematopoietic stem cell transplantation (HSCT). We herein report a case of possible toxoplasmic encephalitis with untreated hairy cell leukemia variant. Magnetic resonance imaging showed multiple nodules with surrounding edema in the entire cerebrum. A polymerase chain reaction analysis for Toxoplasma gondii was negative. Her signs and symptoms fully recovered by empirical therapy with sulfadiazine and pyrimethamine. Toxoplasmic encephalitis may occur in patients who undergo non-allogeneic HSCT for hematological malignancies, even in those who have not been treated.

Abstract
Hypofibrinogenemia (plasma fibrinogen level <150 mg/dl) is occasionally observed after allogeneic hematopoietic stem cell transplantation, and its etiology is often difficult to determine. We herein report that steroids administered for the treatment of graft-versus-host disease (GVHD) are associated with the development of hypofibrinogenemia. We retrospectively analyzed the plasma fibrinogen (Fg) levels in 15 consecutive patients who had been administered 1 mg/kg/day (1 mg/kg group) or 2 mg/kg/day (2 mg/kg group) methylprednisolone for the treatment of Grade II to IV acute GVHD. Hypofibrinogenemia had developed in 8 of the 15 patients (53%) by day 50 after the start of steroid treatment, and was observed in 2 of 6 patients in the 1 mg/kg group and 6 of 9 in the 2 mg/kg group. A significant decrease in the Fg level was observed in the 2 mg/kg group (the median value before starting steroid treatment and that on the 20th day after starting steroid treatment were 506 mg/dl and 180 mg/dl, respectively, P=0.0013). Other possible causes of hypofibrinogenemia, including liver dysfunction or disseminated intravascular coagulation, were confirmed in only 3 patients during the observation period. In conclusion, hypofibrinogenemia commonly occurs in patients treated with steroids, especially those administered 2 mg/kg/day methylprednisolone for the treatment of GVHD.

Abstract
An IAEA handbook presenting transfer parameter values for wildlife has recently been produced. Concentration ratios (CRwo-media) between the whole organism (fresh weight) and either soil (dry weight) or water were collated for a range of wildlife groups (classified taxonomically and by feeding strategy) in terrestrial, freshwater, marine and brackish generic ecosystems. The data have been compiled in an on line database, which will continue to be updated in the future providing the basis for subsequent revision of the Wildlife TRS values. An overview of the compilation and analysis, and discussion of the extent and limitations of the data is presented. Example comparisons of the CRwo-media values are given for polonium across all wildlife groups and ecosystems and for molluscs for all radionuclides. The CRwo-media values have also been compared with those currently used in the ERICA Tool which represented the most complete published database for wildlife transfer values prior to this work. The use of CRwo-media values is a pragmatic approach to predicting radionuclide activity concentrations in wildlife and is similar to that used for screening assessments for the human food chain. The CRwo-media values are most suitable for a screening application where there are several conservative assumptions built into the models which will, to varying extents, compensate for the variable data quality and quantity, and associated uncertainty.

Abstract
Atmospheric carbon dioxide concentrations and climate are regulated on geological timescales by the balance between carbon input from volcanic and metamorphic outgassing and its removal by weathering feedbacks; these feedbacks involve the erosion of silicate rocks and organic-carbon-bearing rocks. The integrated effect of these processes is reflected in the calcium carbonate compensation depth, which is the oceanic depth at which calcium carbonate is dissolved. Here we present a carbonate accumulation record that covers the past 53 million years from a depth transect in the equatorial Pacific Ocean. The carbonate compensation depth tracks long-term ocean cooling, deepening from 3.0-3.5 kilometres during the early Cenozoic (approximately 55 million years ago) to 4.6 kilometres at present, consistent with an overall Cenozoic increase in weathering. We find large superimposed fluctuations in carbonate compensation depth during the middle and late Eocene. Using Earth system models, we identify changes in weathering and the mode of organic-carbon delivery as two key processes to explain these large-scale Eocene fluctuations of the carbonate compensation depth.

Abstract
CONTEXT Medical treatment with a mineralocorticoid receptor (MR) antagonist, which has produced spontaneous remission of bilateral primary aldosteronism (PA), may also produce spontaneous remission of unilateral PA, for which laparoscopic adrenalectomy is recommended. However, few reports exist regarding spontaneous remission after MR antagonist therapy in unilateral PA. OBJECTIVE The aim of this paper is to report a case of unilateral PA with spontaneous remission and reduction of cardiac hypertrophy after long-term spironolactone (SP) therapy. RESULTS A 41-yr-old Japanese male was treated for hypertension and hypokalemia for 5 yr. Primary aldosteronism was diagnosed by a furosemide and upright posture test and a captopril challenge test. Computed tomography imaging showed a 5-mm left-sided adrenal mass. Adrenal vein sampling demonstrated overproduction of aldosterone from the left adrenal gland. Long-term treatment with SP normalized the plasma aldosterone concentration. After discontinuation of SP, the patient's blood pressure, serum potassium level, and plasma aldosterone concentration remained in the normal range. The associated cardiac hypertrophy also improved and continued to resolve even after discontinuation of SP. Although the left adrenal gland tumor was still present on computed tomography after treatment, a furosemide and upright posture test, a captopril challenge test, and a saline loading test produced no evidence of PA. Adrenal vein sampling demonstrated no sign of lateralization. CONCLUSION These results demonstrate that SP not only antagonizes the MR, but also decreases aldosterone synthetic activity, which may produce remission in some patients with unilateral PA.

Abstract
AIMS Mineralocorticoid receptor (MR) blockade is an effective treatment for hypertension and diabetic nephropathy. There are no data on the effects of MR blockade on diabetic peripheral neuropathy (DPN). The aim of this study was to determine whether MRs are present in the peripheral nerves and to investigate the effectiveness of MR blockade on DPN in streptozotocin (STZ)-induced diabetic rats. METHODS Expression of MR protein and messenger RNA (mRNA) was examined in the peripheral nerves using Western blot analysis and RT-PCR. We next studied the effects of the selective MR antagonist eplerenone and the angiotensin II receptor blocker candesartan on motor and sensory nerve conduction velocity (NCV), morphometric changes and cyclooxygenase-2 (COX-2) gene and NF-κB protein expression in the peripheral nerves of STZ-induced diabetic rats. RESULTS Expression of MR protein and mRNA in peripheral nerves was equal to that in the kidney. Motor NCV was significantly improved by 8 weeks of treatment with either eplerenone (39.1 ± 1.2 m/s) or candesartan (46.4 ± 6.8 m/s) compared with control diabetic rats (33.7 ± 2.0 m/s) (p < 0.05). Sensory NCV was also improved by treatment with candesartan or eplerenone in diabetic rats. Eplerenone and candesartan caused significant improvement in mean myelin fibre area and mean myelin area compared with control diabetic rats (p < 0.05). COX-2 mRNA and NF-κB protein were significantly elevated in the peripheral nerves of diabetic rats compared with control rats, and treatment with eplerenone or candesartan reduced these changes in gene expression (p < 0.05). CONCLUSION MR blockade may have neuroprotective effects on DPN.

Abstract
Mitotic chromosomes are essential structures for the faithful transmission of replicated genomic DNA into two daughter cells during cell division. A long strand of DNA is wrapped around a core histone and forms a nucleosome. The nucleosome has long been assumed to be folded into 30-nm chromatin fibers. However, how the nucleosome or 30-nm chromatin fiber is organized into mitotic chromosomes remains unclear, although condensins and topoisomerase IIα are implicated in the condensation process. In fact, what do mitotic chromosomes look like in living cells? When frozen hydrated human mitotic cells were observed using cryo-electron microscopy (cryo-EM), higher-order structures including 30-nm chromatin fibers were not found. We thus propose that the nucleosome fibers in the bulk of mitotic chromosomes do not form 30-nm chromatin fibers but instead exist in a highly irregular state that is locally similar to a polymer melt. We provide new insight into mitotic chromosome structure.

Abstract
For the estimation of radiation doses to organisms, concentration ratios (C ( R )s) of radionuclides are required. In the present study, C(R)s of various elements were obtained as analogues of radionuclides for algae, molluscs, and crustaceans, in eight estuarine areas around Japan. The elements measured were Na, Mg, K, Ca, V, Mn, Fe, Co, Ni, Cu, Rb, Sr, Y, Mo, Cd, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Pb, and U. The geometric mean (GM) values of C(R)s (GM-C(R)s) for alkali and alkaline earth elements, Mo, and U for all biota, as well as V for crustaceans, were less than 100 L/kg, while GM-C(R)s for the other elements were higher. When the obtained GM-C(R)s were compared with the C(R)s recommended in IAEA Technical Report Series 422 for marine organisms, no big differences between them were found; however, several elements (i.e. Cd and U for algae, Mn for molluscs, and Pb for crustaceans) were lower than the recommended C(R)s. In the present study, conversion factors (the ratio of C(R) for the whole body to that for muscle) for molluscs and crustaceans were also calculated, since data on edible parts of these organisms are generally available in the literature. For crustaceans, GM conversion factors of all the elements were more than one. For molluscs, GM conversion factors of rare earth elements and U were slightly higher than those for crustaceans, while GM conversion factors of the other elements were almost the same and less than 10. These results indicate that some elements tend to be concentrated in the internal organs of biota collected in the estuarine areas. For environmental radiological assessment, conversion factors from tissue to whole-body C(R) values are useful parameters.

Abstract
1,4-alpha-Glucan branching enzyme (BE; EC 2.4.1.18) is a key biocatalyst in the synthesis of polysaccharides, and is therefore useful in the production of food ingredients. The BEs evaluated in this study (BE-01 and BE-02) are obtained by fermentation of Bacillus subtilis expressing the BE gene from either Bacillus stearothermophilus strain TRBE14 or Aquifex aeolicus strain VF5. The safety of BE-01 and BE-02 have not been previously evaluated, and therefore, both were subjected to standard toxicological testing. In a battery of standard Salmonella typhimurium strains (TA98, TA100, TA1535, and TA1537) and in Escherichia coli WP2uvrA, both with and without metabolic activation, neither BE-01 nor BE-02 exhibited mutagenic activity. Similarly, neither was associated with clastogenic properties in Chinese hamster ovary cells in an in vitro chromosomal aberration assay. In rats, oral administration of BE-01 or BE-02 at doses of up to 15 mL/kg body weight/day (approximately 870 and 900 mg/kg body weight/day, respectively) for 13 weeks did not produce compound-related clinical signs or toxicity, changes in body weight gain, food consumption, hematology, clinical chemistry, urinalysis, organ weights, or in any gross and microscopic findings. The results of this study support the safety of BE-01 and BE-02 in food production.

Abstract
BACKGROUND We previously reported that a high-sodium diet activates the local renin-angiotensin-aldosterone system (RAAS) in cardiovascular tissues of Dahl salt-sensitive hypertensive (DS) rats. Angiotensin-converting enzyme 2 (ACE2) is a novel regulator of blood pressure (BP) and cardiac function. The effect of blockade of aldosterone or angiotensin II (Ang II) on cardiac angiotensinogen and ACE2 in DS rats is unknown. METHODS The BP, plasma renin activity (PRA), plasma aldosterone concentration (PAC), heart weight, endothelium-dependent relaxation (EDR), and messenger RNA (mRNA) levels of collagen III, angiotensinogen, ACE, and ACE2 in the heart were measured in DS rats and in Dahl salt-resistant (DR) rats fed high or low salt diets. The rats were treated orally with or without eplerenone (100 mg/kg/d), candesartan (10 mg/kg/d), or both drugs combined for 8 weeks. RESULTS A high salt diet increased BP (140%), heart/body weight (132%), and collagen III mRNA levels (146%) and decreased PRA and PAC concomitant with increased expression of cardiac angiotensinogen mRNA and decreased mRNA levels of ACE2 in DS rats. Eplerenone or candesartan significantly decreased the systolic BP from 240 +/- 5 mm Hg to 164 +/- 4 mm Hg or to 172 +/- 10 mm Hg, respectively (P < .05). Eplerenone or candesartan partially improved heart/body weight and cardiac fibrosis, improved EDR and decreased cardiac ACE and angiotensinogen mRNA levels in DS rats. Candesartan increased ACE2 mRNA levels in the heart. Combination therapy normalized BP and further improved cardiac hypertrophy, fibrosis, and EDR. CONCLUSIONS In DS rats, blockade of aldosterone or Ang II protects cardiac hypertrophy and fibrosis by inactivation of the local RAAS in the heart.

Abstract
In some patients with insulinoma, surgery is not possible due to either difficulties in detecting the tumor or advanced age. These patients need medical treatment for hypoglycemia. We report a case of benign insulinoma using the long-acting octreotide formulation, octreotide long-acting repeatable (octreotide LAR), as a medical therapy. A 67-year-old woman was referred to our hospital for examinations of hypoglycemia. A blood sample taken during a hypoglycemic episode revealed low plasma glucose concentration, hyperinsulinemia and a high C-peptide level. An abdominal CT scan demonstrated a hypervascular tumor in the body of pancreas. She was diagnosed with insulinoma. As the patient refused surgical resection of the pancreas tumor, we started to use the somatostatin analogue, octreotide, for treatment of hypoglycemia. After the treatment her plasma glucose levels were elevated and serum immunoreactive insulin (IRI) levels were decreased. For long-term treatment, we changed the treatment from daily subcutaneous injection of octreotide to monthly intramuscular administration of octreotide LAR. This treatment was also effective and hypoglycemic attacks disappeared. Both plasma glucose levels and serum IRI levels were improved. Our case demonstrated that octreotide LAR was useful for long-term medical treatment of insulinoma.

Abstract
The mechanism of overproduction of aldosterone in primary aldosteronism is unclear. The intraadrenal renin-angiotensin system (RAS) has been suggested to possess the functional role of the synthesizing aldosterone and regulating blood pressure. In order to clarify the pathophysiological roles of adrenal RAS in aldosterone-producing adenoma (APA), we studied the expressions of the messenger RNAs (mRNAs) of renin, angiotensinogen, type 1 (AT1R) and type 2 angiotensin II receptor (AT2R), CYP11B1 (11 beta-hydroxylase gene) and CYP11B2 (aldosterone synthase gene) in 8 patients with angiotensin II-responsive (ATII-R) APA and compared them with the expressions of the same mRNAs in 8 patients with angiotensin II-unresponsive (ATII-U) APA. Quantification of the mRNA of each gene was done using a real-time polymerase chain reaction with specific primers. There were no significant differences between ATII-R APA and ATII-U APA in the mRNA levels of renin, angiotensinogen, AT1 R, CYP11B1 and CYP11B2. The amount of AT2R mRNA was significantly higher in the patients with ATII-R APA than in those with ATII-U APA (p<0.05). These results may suggest that AT2R partially contributes to the overproduction of aldosterone in ATII-R APA.

Abstract
A large amount of metaphase chromosomes were isolated from synchronized human cell lines by a polyamine procedure. All the chromosomal proteins extracted by an acetic acid extraction method were fully dissolved into the sample solutions for isoelectric focusing (IEF) or radical free and highly reduced (RFHR) two-dimensional electrophoreses (2-DEs). As a result, well-separated and highly reproducible 2-DE patterns were obtained. This could not be attained by an ordinary acetone precipitation method. The 2-DE patterns visualized using Coomassie Brilliant Blue (CBB) staining indicated that more than one hundred proteins were involved in the isolated metaphase chromosomes, although the most abundant proteins, histones, occupied a greater part of the chromosomal proteins. It was also shown that colcemid treatment for cell cycle synchronization had little effect on the 2-DE pattern compared to that obtained without the treatment. Furthermore, no significant differences were observed in the 2-DE patterns among the chromosomal proteins prepared from two different human cell lines, BALL-1 and K562. However, 2-DE analysis of isolated metaphase chromosomes from HeLa cells apparently showed a smaller number of proteins than the BALL-1 and K562 cell lines at a neutral pI range. The present study paves the way for elucidating protein composition of human metaphase chromosomes.
