Abstract
COVID-19 mRNA vaccines manufactured by Pfizer-BioNTech and Moderna have been approved in many countries, and have been administered since 2020. Recent reports of mRNA vaccination exacerbating autoimmune hematologic disorders, such as immune thrombocytopenia or autoimmune hemolytic anemia, have caught the attention of the general public, resulting in alarm over the risks of serious consequences. Meanwhile, in very rare cases, vaccination was reported to trigger new onset of hemolytic anemia. However, it remains unknown whether this was a transient reaction or a persistent event, because all cases reported to date were immediately treated with corticosteroids or rituximab. Here, we present a case of newly diagnosed cold agglutinin disease after a third COVID-19 mRNA vaccination. The patient was followed for 4 months without treatment and continued to exhibit high levels of cold agglutinin and aggregation of red blood cells. The present case indicates that the disease can become chronic, and provides insights into the pathogenesis and treatment strategies.

Abstract
BACKGROUND There is growing interest in examining objective markers for early identification and behavioral intervention to prevent dementia and mild cognitive impairment in clinical and community settings. OBJECTIVE To investigate the association between salivary alpha-amylase as an objective measure of psychological stress response and mild cognitive impairment for the implication of psychological stress in the development of mild cognitive impairment. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study involved 865 participants aged ≥ 65 years. A saliva sample was collected in the morning, and the levels of salivary alpha-amylase were assayed. Mild cognitive impairment was evaluated using the Japanese version of the Montreal Cognitive Assessment; a score < 26 was indicative of mild cognitive impairment. A multivariable logistic regression model was used to examine the association of salivary alpha-amylase and mild cognitive impairment after adjusting for age, sex, current drinking status, current smoking status, body mass index, hypertension, diabetes mellitus, physical activity, education, social support, social network, and heart rate variability. RESULTS Salivary alpha-amylase was associated with mild cognitive impairment (the multivariable-adjusted odds ratio [95% confidence interval] for the 1-standard deviation increment of log-transformed salivary alpha-amylase was 1.24 [1.07-1.44]). This significant association persisted after adjusting for various confounding factors. CONCLUSION Elevation of salivary alpha-amylase was associated with mild cognitive impairment among Japanese community-dwelling older adults. This suggests that salivary alpha-amylase is a useful objective marker of psychological stress responses associated with mild cognitive impairment.

Abstract
BACKGROUND There has been no report about outcome of pitavastatin versus atorvastatin therapy in high-risk patients with hypercholesterolemia. METHODS Hypercholesterolemic patients with one or more risk factors for atherosclerotic diseases (n = 664, age = 65, male = 54%, diabetes = 76%, primary prevention = 74%) were randomized to receive pitavastatin 2 mg/day (n = 332) or atorvastatin 10 mg/day (n = 332). Follow-up period was 240 weeks. The primary end point was a composite of cardiovascular death, sudden death of unknown origin, nonfatal myocardial infarction, nonfatal stroke, transient ischemic attack, or heart failure requiring hospitalization. The secondary end point was a composite of the primary end point plus clinically indicated coronary revascularization for stable angina. RESULTS The mean low-density lipoprotein cholesterol (LDL-C) level at baseline was 149 mg/dL. The mean LDL-C levels at 1 year were 95 mg/dL in the pitavastatin group and 94 mg/dL in the atorvastatin group. There were no differences in LDL-C levels between both groups, however, pitavastatin significantly reduced the risk of the primary end point, compared to atorvastatin (pitavastatin = 2.9% and atorvastatin = 8.1%, HR, 0.366; 95% CI 0.170-0.787; P = 0.01 by multivariate Cox regression) as well as the risk of the secondary end point (pitavastatin = 4.5% and atorvastatin = 12.9%, HR = 0.350; 95%CI = 0.189-0.645, P = 0.001). The results for the primary and secondary end points were consistent across several prespecified subgroups. There were no differences in incidence of adverse events between the statins. CONCLUSION Pitavastatin therapy compared with atorvastatin more may prevent cardiovascular events in hypercholesterolemic patients with one or more risk factors for atherosclerotic diseases despite similar effects on LDL-C levels.

Abstract
Therapeutic blocking antibodies against programmed death 1 (PD1) and cytotoxic T-lymphocyte antigen 4 (CTLA4) are applied for advanced cancer therapy, but induce a wide range of immune-related adverse events. In our recent case of a 52-year-old female doctor suffering from breast cancer having metastasized to the lung and liver, it was decided to use nivolumab to prevent the disease progressing after excisional surgeries and multiple chemotherapies. One month after completing the nivolumab course, fatigue, hypoglycemia and hypotension developed and isolated ACTH deficiency (IAD) was diagnosed. A further month later, under steroid supplementation, hyperglycemia emerged alongside thirst and polydipsia, prompting a diagnosis of fulminant type 1 diabetes (FT1D). Her susceptibility to type 1 diabetes was examined by HLA haplotype and CTLA4 gene polymorphism analyses. Polymorphisms CT60G>A and +49G>A in CTLA4 both generated a GG genotype. Our patient manifested one of the rarest combinations of autoimmune disease induced by nivolumab. Whereas the HLA haplotype was unsusceptible to autoimmune type 1 diabetes, polymorphisms of CTLA4, the antibody of which frequently causes hypophysitis, were susceptible to FT1D. Peripheral modulation of activated T cells, mainly by PD-1 antibodies, induced FT1D associated with IAD in patients with CTLA4 polymorphism. This case reveals hints of the T-cell etiology in T1D and evidence of CTLA4 involvement in IAD.

Abstract
AIM To elucidate the mechanisms involved in the sequential use of SGLT2 and DPP4 inhibitors (SGLT2i and DPP-4i). METHODS Twenty-six type-2 diabetes mellitus patients were recruited into a stepped regimen of 100 mg of canagliflozin daily from day 1, supplemented with 20 mg of teneligliptin daily from day 4. Glucose (Glu), insulin and glucagon were measured at fasting and after ingesting a mixed meal on days 1, 4 and 6. RESULTS Canagliflozin decreased fasting plasma glucose to an extent inversely proportional to the change in the glucagon-to-insulin (G/I) ratio. This correlation at fasting was maintained when adding teneligliptin, while the change in the area under the curve of Glu (GluAUC) correlated closely with that in the G/I ratio at fasting and 60 min with canagliflozin. Moreover, these correlations persisted at 60 and 120 min postprandially, but not at fasting on day 6 when teneligliptin was added. CONCLUSION The result suggested that the dominant mechanism responsible for the glucose metabolism reflected in the G/I ratio was attributable to SGLT2i and that its active mechanism persisted, despite adding a DPP-4i.

Abstract
Even mass neutron-rich niobium isotopes are among the principal contributors to the reactor antineutrino energy spectrum. They are also among the most challenging to measure due to the refractory nature of niobium, and because they exhibit isomeric states lying very close in energy. The β-intensity distributions of ^{100gs,100m}Nb and ^{102gs,102m}Nb β decays have been determined using the total absorption γ-ray spectroscopy technique. The measurements were performed at the upgraded Ion Guide Isotope Separator On-Line facility at the University of Jyväskylä. Here, the double Penning trap system JYFLTRAP was employed to disentangle the β decay of the isomeric states. The new data obtained in this challenging measurement have a large impact in antineutrino summation calculations. For the first time the discrepancy between the summation model and the reactor antineutrino measurements in the region of the shape distortion has been reduced.

Abstract
Three observables of interest for present and future reactors depend on the β decay properties of the fission products: antineutrinos from reactors, the reactor decay heat and delayed neutron emission. In these proceedings, we present new results from summation calculations of the first two quantities quoted above, performed with evolved independent yields coupled with fission product decay data, from various nuclear data bases or models. New TAGS results from the latest experiment of the TAGS collaboration at the JYFL facility of Jyväskylä will be displayed as well as their impact on the antineutrino spectra and the decay heat associated to fission pulses of the main actinides.

Abstract
PURPOSE The authors studied the effects of changes in packaging solution temperature on the development of glistening in acrylic intraocular lenses (AcrySof, Alcon). METHODS Glistening was examined by slit lamp at each condition. In Experiment 1, AcrySof lenses were soaked in physiologic saline adjusted to 15 degrees C and 37 degrees C in an incubator. In Experiment 2, AcrySof lenses were soaked in physiologic saline adjusted to 37 degrees C and 60 degrees C for 5 min, then stored in physiologic saline adjusted to 15 degrees C. In Experiment 3, glistening formation was induced in AcrySof lenses by soaking them in warm water (37 degrees C). The lenses were allowed to dry at 15 degrees C and then soaked in physiologic saline adjusted to 15 degrees C. After storage of dry AcrySof lenses at 37 degrees C in an incubator for 10 months followed by soaking in physiologic saline adjusted to 15 degrees C, glistening formation was evaluated in Experiment 4. RESULTS Glistening became observable after 1 month, despite the temperature having been lowered to 15 degrees C. No glistening was observed in the lenses soaked in physiologic saline adjusted to 37 degrees C after 5 min, but glistening was observed 1 month after soaking. When allowed to dry at 15 degrees C, the glistening decreased. After 1 month of soaking at 15 degrees C, glistening was again observable. CONCLUSIONS AcrySof lenses soaked in warm water for a short time may change characteristics, and therefore, close monitoring of the temperature and time of soaking is necessary to prevent glistening formation.

Abstract
AIMS To investigate the efficacy and safety of empagliflozin in subgroups based on body mass index (BMI) and age, using a pooled data set from Japanese patients with type 2 diabetes mellitus (T2DM). METHODS Pooled data from 1403 patients treated with empagliflozin at 10mg/day or 25mg/day in three clinical studies (≥52week treatment) were stratified by baseline BMI (<22, 22 to <25 and ≥25kg/m2) and baseline age (<50, 50 to <65 and ≥65years). RESULTS Empagliflozin at 10mg/day and 25mg/day reduced mean glycated hemoglobin (HbA1c) (-0.77 to -0.87% and -0.76 to -0.97%, respectively), mean fasting plasma glucose (FPG) (-20.79 to -27.06mg/dL and -26.08 to -29.60mg/dL) and mean body weight (-3.4 to -4.7% and -3.7 to -4.7%) in all subgroups of baseline BMI and age, regardless of age and degree of obesity. Adverse events were observed in approximately 70-80% patients in BMI and age subgroups of both empagliflozin groups. No hypoglycemia requiring assistance was observed. Neither UTI nor genital infection rates differed markedly among the BMI and age subgroups. Volume depletion was increased in patients ≥65years of age as compared to younger patients. CONCLUSIONS Empagliflozin was well tolerated and improved HbA1c, FPG and body weight in all BMI and age subgroups of Japanese patients with T2DM, regardless of age and degree of obesity. Empagliflozin is considered to be effective and well tolerated for treating a wide range of Japanese patients with T2DM. TRIAL REGISTRATION Study 1 (NCT01193218), Study 2 (NCT01289990) and Study 3 (NCT01368081).

Abstract
BACKGROUND Lowering cholesterol levels decreases the risk of atherosclerotic diseases. Effective ways to stably reduce LDL-C level are warranted in type 2 diabetic patients, a high-risk population for CVD, with various anti-diabetic therapeutic background. The RESEARCH study focuses on LDL-C reduction in this population along with modifications of the lipid profiles. We evaluated long-term ezetimibe add-on therapy in T2DM patients with hypercholesterolemia. METHODS In a randomized, multicenter, open-label, prospective study, a total of 109 T2DM patients not attaining LDL-C target value despite first-line dose statin (10 mg of atorvastatin or 1 mg of pitavastatin) therapy in Japan were recruited. We investigated the difference in cholesterol lowering effect between ezetimibe (10 mg) add-on statin (EAT) group and double-dose statin (DST) group. Changes of parameters related to atherosclerotic event risks were assessed. RESULTS The reduction of LDL-C was larger in the EAT group (28.3%) than in the DST group (9.2%) at 52 weeks as well as the primary endpoint of 12 weeks. EAT achieved significant lower levels of TC and apo B, respectively. Both treatments attained significant reduction in sd-LDL-C or hsCRP on this long-term basis. Notably, sd-LDL-C in EAT reduced as low as 36.1 ± 14.9 mg/dl to reach near the threshold (35.0 mg/dl) for atherosclerosis with significantly higher achievement rate (55.6%) than DST treatment. Simultaneously, hsCRP reduction by EAT attained as low value as 0.52 ± 0.43 mg/l. CONCLUSIONS In the present 52-week long-term period, ezetimibe add-on therapy showed a robust advantage in lowering LDL-C and in attaining target LDL-C values compared with the doubling of statin dose. Moreover, it's meaningful that sd-LDL, powerfully atherogenic lipoprotein, exhibited prominent decrease consistently prominently by ezetimibe add-on therapy. DM patients with hypercholesterolemia are at high risk for CAD, and adding ezetimibe onto usual-dose statin treatment in Japan has been suggested as the first-line therapy for those DM patients who failed to attain the target LDL-C value (UMIN000002593).

Abstract
Relatively large amounts of inorganic polyphosphate [poly(P)] (400 μM) have been found in normal osteoblasts. The effect of poly(P) with an average chain length of 65 phosphate residues on cell calcification was therefore investigated with the use of MC3T3-E1 cells. Expression of both osteopontin and osteocalcin was induced by poly(P) (0.1 ~ 1 mM), and cells treated with poly(P) were strongly stained by alizarin red. In addition, the level of alkaline phosphatase activity induced in poly(P)-treated cells was two-fold higher than that in either orthophosphate-treated or control cells but not higher than that in cells treated with β-glycerophosphate and ascorbic acid. In contrast, however, polyphosphatase activities were activated by poly(P) treatment to levels up to six-fold greater than that in controls. MC3T3-E1 cells may utilize poly(P) as a phosphate source for calcification rather than phosphate sources that are mainly produced by ALPase. Poly(P)-dependent induction of polyphosphatase activities may therefore promote calcification in MC3T3-E1 cells.

Abstract
Background There exists a subpopulation of T2DM in whom first-line doses of statin are insufficient for optimally reducing LDL-C, representing a major risk of CVD. The RESEARCH study focuses on LDL-C reduction in this population along with modifications of the lipid profiles leading to residual risks. Methods Lipid changes were assessed in a randomized, multicenter, 12-week, open-label study comparing a high-potency statin (10mg of atorvastatin or 1mg of pitavastatin) plus ezetimibe (EAT: n = 53) with a double dose of statin (20mg of atorvastatin or 2mg of pitavastatin) (DST: n = 56) in DM subjects who had failed to achieve the optimal LDL-C targets. Lipid variables were compared with a primary focus on LDL-C and with secondary focuses on the percentage of patients who reached the LDL-C targets and changes in the levels of RLP-C (remnant like particle cholesterol) and sd-LDL-C, two characteristic atherogenic risks of DM. Results The reduction of LDL-C (%), the primary endpoint, differed significantly between the two groups (-24.6 in EAT vs. -10.9 in DST). In the analyses of the secondary endpoints, EAT treatment brought about significantly larger reductions in sd-LDL-C (-20.5 vs. -3.7) and RLP-C (-19.7 vs. +5.5). In total, 89.4% of the patients receiving EAT reached the optimized treatment goal compared to 51.0% of the patients receiving DST. The changes in TC (-16.3 vs. -6.3) and non-HDL-C (-20.7 vs. -8.3) differed significantly between the two groups. Conclusion Ezetimibe added to high-potency statin (10 mg of atorvastatin or 1 mg of pitavastatin) was more effective than the intensified-dose statin (20 mg of atorvastatin or 2 mg of pitavastatin) treatment not only in helping T2DM patients attain more LDL-C reduction, but also in improving their atherogenic lipid profiles, including their levels of sd-LDL-C and RLP-C. We thus recommend the addition of ezetimibe to high-potency statin as a first line strategy for T2DM patients with insufficient statin response.

Abstract
The antineutrino spectra measured in recent experiments at reactors are inconsistent with calculations based on the conversion of integral beta spectra recorded at the ILL reactor. (92)Rb makes the dominant contribution to the reactor antineutrino spectrum in the 5-8 MeV range but its decay properties are in question. We have studied (92)Rb decay with total absorption spectroscopy. Previously unobserved beta feeding was seen in the 4.5-5.5 region and the GS to GS feeding was found to be 87.5(25)%. The impact on the reactor antineutrino spectra calculated with the summation method is shown and discussed.

Abstract
SGLT2 is a low affinity, high capacity glucose co-transporter, almost exclusively expressed in the kidney cortex. Inhibition of SGLT2 has been shown to increase the daily 50g or more urinary glucose excretion, as compared to placebo, leading to a reduction in blood glucose levels and indicated only for the treatment of type 2 diabetes. In Japan 6 species of SGLT2 inhibitors have already been sold and reported to results in a decrease of FPG by 14.4 to 45.8 (mg/dL), in a reduction of HbA1c by 0.35 to 1.24% and in loss of body weight by 1.29 to 2.50(kg). There is less effect of the SGLT2 inhibitor in diabetic subjects with renal impairment and the reduction in HbA1c and FPG will be approximately half of the average in those with 30 ≤ eGFR ≤ 59. The position of SGLT2 inhibitors would be considered as the drug administered in combination or add-on therapy when the young obese type 2 diabetics without renal impairment has not yet reached to the glycemic target with other drugs although in AACE consensus statement of 2013, it has been shelved for inexperienced use with respect to the positioning of the SGLT2 inhibitors.

Abstract
African trypanosomosis is a potentially fatal disease that is caused by extracellular parasitic protists known as African trypanosomes. These parasites inhabit the blood stream of their mammalian hosts and produce a number of pathological features, amongst which is anemia. Etiology of the anemia has been partly attributed to an autoimmunity-like mediated erythrophagocytosis of de-sialylated red blood cells (dsRBCs) by macrophages. Lactose infusion to infected animals has proven effective at delaying progression of the anemia. However, the mechanism of this anemia prevention is yet to be well characterized. Here, the hypothesis of a likely induced further modification of the dsRBCs was investigated. RBC membrane galactose (RBC m-GAL) and packed cell volume (PCV) were measured during the course of experimental trypanosomosis in mice infected with Trypanosoma congolense (stb 212). Intriguingly, while the membrane galactose on the RBCs of infected and lactose-treated mice (group D) decreased as a function of parasitemia, that of the lactose-untreated infected group (group C) remained relatively constant, as was recorded for the uninfected lactose-treated control (group B) animals. At the peak of infection, the respective cumulative percent decrease in PCV and membrane galactose were 30 and 185 for group D, and 84 and 13 for group C. From this observed inverse relationship between RBCs membrane galactose and PCV, it is logical to rationalize that the delay of anemia progression during trypanosomosis produced by lactose might have resulted from an induction of galactose depletion from dsRBCs, thereby preventing their recognition by the macrophages.

Abstract
Aims Hypercholesterolemia coexisting with diabetes still requires clinical intervention to manage the high risk of cardiovascular disease it poses. No second-step strategy is established, however, for cases where strong statins fail to bring cholesterol down to target levels. In this study we seek to demonstrate the superior effect of ezetimibe in combination with strong statins to reduce LDL-C in Japanese patients suffering from both T2DM and hyper LDL-cholesterolemia. Methods T2DM outpatients (109 patients from 16 institutes) who failed to achieve the target LDL-C value were recruited and randomly assigned to two groups, a double-dose-statin group and ezetimibe-plus-statin group. Follow-ups were scheduled at 0, 12, 26, and 52 weeks. The primary endpoint was the percentage change in the level of LDL-C from baseline to 12 weeks. Interim results We could successfully create randomized (gender, age, LDL-C, HbA1c, etc.) two groups except for slight differences in apolipoprotein-B and sd-LDL. Conclusions RESEARCH is the first prospective, parallel-group, multicenter study comparing a double dose of strong statin with ezetimibe plus strong statin for T2DM patients. The RESEARCH study will provide reliable evidence with which to establish a clinical strategy for diabetics who fail to achieve the target LDL-C value.

Abstract
AIMS We investigated the prevalence and characterization of asymptomatic pancreatic tumors in response to our experience of asymptomatic insulinoma. METHODS A patient with a moderately low glucose level and pancreatic incidentaloma detected by CT was examined. Pancreas specimens from 423 autopsy cases were also pathologically examined systematically by hematoxylin-eosin staining. RESULTS The examined patient showed no profile characteristic of insulinoma by fasting or loading tests, however, ASVS led to diagnosis of insulin-producing tumor. The tumor was resected with the pancreatic body and tail and revealed to be 10 mm in diameter, with 98.5% of the cells positive for insulin. Pathological evaluation confirmed a well-differentiated endocrine pancreatic tumor, which was suggestive of an incidentally detected asymptomatic insulinoma. Microscopic evaluations of pancreatic specimens from 423 autopsy cases revealed pancreatic monotonous lesions in 6 cases (1.42%). In 4 autopsy specimens large enough for immuno-histochemical evaluation, the lesions were positive for glucagon but negative for insulin. CONCLUSIONS As concerns the present study, retrospective immunohistochemical investigation in autopsy cases revealed the presence of asymptomatic glucagonoma but no asymptomatic insulinoma. Advances in diagnostic imaging, however, might raise the probability of detecting early asymptomatic stages of insulinoma incidentally. ASVS appears to be sensitive even for asymptomatic incidental insulinomas.

Abstract
Immunohistochemical distribution of the Ca2+ binding proteins S100A1, S100A2, S100A4, S100A6, S100B, and bone morphogenetic protein (BMP) in chondro-osseous tumors and lesions, both benign and malignant, was investigated using specific anti S100 protein and BMP antibodies. Chondrogenic tumor cells of chondro-osseous lesions were characterized by the presence of marked staining for S100B and BMP, while they were only faintly reactive for S100A1, S100A2, S100A4 and S100A6. Dense fibrous connective tissue in osseous tumor and ossifying fibroma showed moderate immunoreactivity for S100A1, S100A4 and BMP. Immunoreactivity of S100A2, prominent in epidermal basal cells and associated or homologous cells of epidermal tumors or skin appendages tumors, was not found in cartilage and bone forming cells. Biological roles of S100B in chondroid cells may involve Ca2+-signaling in precalcified tissue, cytoskeletal protein organization and matrix formation since glycosaminoglycan synthesis is mediated by calcium ions. S100B positive cells in chondro-osseous structures also strongly expressed BMP. The present study allowed us to conclude that among the S100 proteins, the S100B in particular and S100A1, S100A4 and S100A6 but not S100A2 may be involved in the process of tumorigenesis of chondro-osseous tumors and BMP may have an important role in the chondroid and osseous differentiation. The detailed biological role of S100 proteins in chondro-osseous tumors is under investigation.

Abstract
Inorganic polyphosphate (poly(P)) can promote binding between fibroblast growth factors and their receptors and enhance osteoblastic cell differentiation and calcification. This study evaluated the possibilities for poly(P) adsorbed onto interconnected porous calcium hydroxyapatite (IP-CHA) as a new bone regeneration material. Prepared 1%, 5%, 25% and 50% poly(P)/IP-CHA composites showed the elution peak of poly(P) between 15 and 20 min, respectively, with the highest value from 50% poly(P)/IP-CHA in vitro. Histologically, at 1 week of placement into the femur of rabbits, granulation tissue had penetrated into the pores in all composites and IP-CHA as a control. In contrast, at 2 weeks of placement, newly formed lamellar bone was found in all groups, although a higher amount of bone regeneration was obviously formed in the 25% and 50% poly(P)/IP-CHA with a significantly higher value of bone regeneration ratio of 50% poly(P)/IP-CHA. These results indicate that 25% and 50% poly(P)/IP-CHA composites may enhance initial bone regeneration.

Sixteen strains of aerobic bacteria which contain bacteriochlorophyll a were isolated from the samples collected in aerobic marine environments: thalli of Enteromorpha linza, Porphyra sp., Sargussum horneri; beach sand; and the surface seawater from Aburatsubo Inlet. When they occurred, their proportions among the aerobic heterotrophic populations ranged from 0.9 to 1.1% in the seaweed samples and from 1.2 to 6.3% in the beach sand samples and were 0.9% in the seawater sample. The results suggested that the aerobic photopigmented bacteria widely inhabit aerobic marine environments.

Abstract
The activities of the enzymes to eliminate reactive oxygen species prevent the progression of atherosclerosis. We conducted a cross-sectional study among 3234 people that underwent total health check-up service, and studied the relationship between the serum superoxide dismutase (SOD) activity and risk factors of atherosclerosis or carotid artery intima-media thickness (IMT). Serum SOD activity negatively correlated with body mass index (BMI), systolic and diastolic blood pressure, serum triglyceride (TG) concentration and serum glucose concentration. Low serum SOD activity positively correlated with the carotid IMT thickening. But on the other hand, existence of carotid artery plaque positively correlated with serum SOD activity especially among men. Serum SOD activity negatively correlated with the components of metabolic syndrome and low serum SOD activity seems to be an independent risk of the thickening of carotid IMT. On the other hand, serum SOD activity level seems to elevate limitedly but reactively to the status of increased oxidative stress, such as carotid plaque formation.

Abstract
Basic fibroblast growth factor (bFGF) and inorganic polyphosphate (poly(P)) have been recognized as therapeutic agents that enhance bone regeneration. It has also been shown that poly(P) may enhance the mitogenic activity of bFGF. The purpose of this study is to evaluate the combined effect of bFGF and poly(P) on bioactivities of osteoblasts and initial bone regeneration in vitro and in vivo. MC3T3-E1 cells were treated with bFGF, poly(P) or bFGF+poly(P), then subjected to cell proliferation assay, alkaline phosphatase (ALP) activity measurement, quantitative real-time reverse transcription-polymerase chain reaction and Alizarin S Red staining. In an in vivo study, bFGF-, poly(P)- and bFGF+poly(P)-modified interconnected porous hydroxyapatite (IPHA) complexes were fabricated, and placed into the femurs of rabbits to evaluate new bone formation histologically and histomorphometrically. The highest enhancement of cell proliferation were observed in those treated with bFGF+poly(P) on days 5 and 7. Cells treated with bFGF+poly(P) also exhibited increased ALP activity on days 5 and 10, up-regulated mRNA levels of osteocalcin and osteopontin, and enhanced calcification when compared to the non-treated cells. In vivo, the highest bone formation ratio was observed in bFGF+poly(P)-modified IPHA complexes. This study indicated that co-application of bFGF and poly(P) may provide enhanced bone formation by modulating cell proliferation and the mineralization process. It is anticipated that a combined application of bFGF and poly(P) can provide a novel method for bone regeneration in clinical use.

Abstract
The molecular mechanisms of vertebrate ZZ/ZW-type sex-determining systems remain unclear. We recently indicated that a W-linked gene, DM-W is a likely ovary-determining gene in Xenopus laevis. We first examined whether Cyp19 for estrogen-synthesizing enzyme P450 aromatase and Foxl2 showed female-specific expression in developing gonads. Both genes showed much higher expression in ZW than in ZZ gonads during and after sex determination. Importantly, transgenic ZZ gonads expressing exogenous DM-W at the sex-determining stage showed a ZW-type pattern of Cyp19 and Foxl2 expression. These results suggest that DM-W up-regulates Cyp19 and Foxl2 expression to guide primary ovary development in X. laevis.

Abstract
A 75-year-old man with cardiac amyloidosis was presumptively diagnosed as having cardiac syndrome X. Early clinical presentation was repeated episodes of angina pectoris without angiographically significant stenosis of the coronary arteries, so the diagnosis of cardiac syndrome X was initially given. However, his anginal symptoms worsened despite appropriate medication. He developed congestive heart failure and died 8 years after his first anginal symptoms. Autopsy revealed amyloid deposits in the intramyocardial coronary arteries with luminal obstruction, with little in the epicardial coronary arteries or myocardium. Therefore, the definitive diagnosis was cardiac amyloidosis.
