Abstract
This study aimed to investigate whether renal denervation (RDN) reduces blood pressure and attenuates cardiac hypertrophy with decreasing sympathetic activity in spontaneously hypertensive rats (SHRs), a model of essential hypertension, during the established phase of hypertension. We performed RDN or sham operation in 15-weeks-old SHRs. Thirty days after RDN, mean blood pressure measured by telemetry, heart weight, left ventricular wall thickness assessed by echocardiography, and urinary norepinephrine levels were significantly decreased in the RDN group compared to the Sham group. Furthermore, oxidative stress, as indicated by thiobarbituric acid reactive substances, in the rostral ventrolateral medulla, a pivotal region regulating basal sympathetic tone, was significantly decreased in the RDN group. In conclusion, RDN reduces blood pressure and attenuates cardiac hypertrophy with sympathoinhibition in the established phase of hypertension in SHRs. These findings highlight the sympathoinhibitory effect of RDN and suggest that RDN may be a potential therapy for hypertensive cardiac hypertrophy. Renal denervation reduces blood pressure and attenuates cardiac hypertrophy with sympathoinhibition in the established phase of hypertension in spontaneously hypertensive rats. This study highlights the sympathoinhibitory effect of renal denervation and suggests that renal denervation may be a potential therapy for hypertensive cardiac hypertrophy.

Abstract
Electrocardiographic left ventricular hypertrophy (LVH) could predict adverse renal outcomes in patients with hypertension. This study aimed to investigate the association between electrocardiographic LVH and future decline in renal function in the general population using a dataset of population-based health checkups from 2010 to 2019 including 19,825 participants. Electrocardiographic LVH was defined according to the Minnesota code. Renal function decline was defined as a decrease of ≥ 25% in the estimated glomerular filtration rate from baseline to < 60 mL/min/1.73 m2. Electrocardiographic LVH was found in 1263 participants at the baseline visit. The mean follow-up period was 3.4 ± 1.9 years. The incidence rates of renal function decline were 0.30 and 0.78 per 100 person-years in the non-LVH group and LVH groups, respectively. Electrocardiographic LVH was associated with the risk for renal function decline in the adjusted analysis (hazard ratio 1.69, 95% confidence interval 1.14-2.50, P = 0.009). This association was comparable across subgroups stratified by age, sex, body mass index, diagnosed hypertension, systolic blood pressure, hemoglobin A1c, and urinary protein. This study underscores the usefulness of electrocardiographic LVH to detect high-risk individuals for renal function decline in the setting of health checkups in the general population.

Abstract
In magnetic fusion plasmas, a transport barrier is essential to improve the plasma confinement. The key physics behind the formation of a transport barrier is the suppression of the micro-scale turbulent transport. On the other hand, long-range transport events, such as avalanches, has been recognized to play significant roles for global profile formations. In this study, we observed the impact of the avalanche-type of transport on the formation of a transport barrier for the first time. The avalanches are found to inhibit the formation of the internal transport barrier (ITB) observed in JT-60U tokamak. We found that (1) ITBs do not form in the presence of avalanches but form under the disappearance of avalanches, (2) the surface integral of avalanche-driven heat fluxe is comparable to the time rate change of stored energy retained at the ITB onset, (3) the mean E × B flow shear is accelerated via the ion temperature gradient that is not sustained under the existence of avalanches, and (4) after the ITB formation, avalanches are damped inside the ITB, while they remain outside the ITB.

Abstract
The mechanisms by which physical exercise benefits brain functions are not fully understood. Here, we show that vertically oscillating head motions mimicking mechanical accelerations experienced during fast walking, light jogging or treadmill running at a moderate velocity reduce the blood pressure of rats and human adults with hypertension. In hypertensive rats, shear stresses of less than 1 Pa resulting from interstitial-fluid flow induced by such passive head motions reduced the expression of the angiotensin II type-1 receptor in astrocytes in the rostral ventrolateral medulla, and the resulting antihypertensive effects were abrogated by hydrogel introduction that inhibited interstitial-fluid movement in the medulla. Our findings suggest that oscillatory mechanical interventions could be used to elicit antihypertensive effects.

Abstract
The pathogenesis of hypertension is multifactorial and highly complex. Basic research plays critical roles in elucidating the complex pathogenesis of hypertension and developing its treatment. This review covers recent topics in basic research related to hypertension in the following six parts: brain/autonomic nervous system, kidney, vascular system, potential treatments, extracellular vesicles, and gut microbiota. The brain receives afferent nerve inputs from peripheral organs, including the heart, kidneys, and adipose tissue, and humoral inputs from circulating factors such as proinflammatory cytokines and leptin, which are involved in the regulation of central sympathetic outflow. In the kidneys, changes in Wnt/β-catenin signaling have been reported in several hypertensive models. New findings on the renin-angiotensin-aldosterone system in the kidneys have also been reported. Sirtuin 6, which participates in various cellular functions, including DNA repair, has been shown to have protective effects on the vascular system. Skin water conservation, mediated by skin vasoconstriction and the accumulation of osmolytes such as sodium, has been found to contribute to hypertension. Studies of rivaroxaban and sodium-glucose cotransporter-2 inhibitors as drug repositioning candidates have been performed. Extracellular vesicles have been shown to be involved in novel diagnostic approaches and treatments for hypertension as well as other diseases. In gut microbiota studies, interactions between microbiota and antihypertensive drugs and potential pathophysiology linking microbiota and COVID-19 have been reported. It can be seen that inter-organ communication has received particular attention from these recent research topics. To truly understand the pathogenesis of hypertension and to develop treatments for conquering hypertension, interresearcher communication and collaboration should be further facilitated. This mini-review focuses on recent topics on basic research in hypertension from the several points of view. The recent topics indicate that inter-organ communication has received particular attention. Interresearcher communication and collaboration should also be further facilitated to truly understand the complex pathogenesis of hypertension and to develop the treatments.

Abstract
BACKGROUND Little is known about nationwide temporal trends in the clinical characteristics and treatment of dilated cardiomyopathy (DCM) in Japan.Methods and Results: We collected data regarding demographics, echocardiography, and treatment of DCM between 2003 to 2013 from Clinical Personal Records, a national registry organized by the Japanese Ministry of Health, Labour, and Welfare. Among the 40,794 DCM patients screened, 27,702 with left ventricular ejection fraction (LVEF) <50% and age ≥18 years were enrolled in this study and divided into 3 groups according to registration year: Group 1, 2003-2005 (10,006 patients); Group 2, 2006-2010 (11,252 patients); and Group 3, 2011-2013 (6,444 patients). Over time, there were decreases in age at registration (mean [±SD] 58.6±13.0 vs. 56.8±13.8 vs. 56.2±13.8 years; P<0.001) and LVEF (33.5±10.0% vs. 31.1±9.9% vs. 29.2± 9.7%; P<0.001), and an increase in patients with New York Heart Association Class III-IV (28.2% vs. 35.2% vs. 41.0%; P<0.001). The use of β-blockers (59.1% vs. 79.3% vs. 87.8%; P<0.001) and mineralocorticoid receptor antagonists (30.6% vs. 35.8% vs. 39.7%; P<0.001) increased over time. In multivariate analysis, male sex, systolic blood pressure, chronic kidney disease, hemoglobin, and registration year were positively associated, whereas age and LVEF were negatively associated, with β-blocker prescription. CONCLUSIONS Although the clinical characteristics of DCM changed, the implementation of optimal medical therapy for DCM increased from 2003 to 2013 in Japan.

Abstract
It is essential for oncology pharmacists to update their knowledge, skills, and ethical attitudes. The Japanese Society of Pharmaceutical Oncology is an academic society for healthcare professionals involved in cancer treatment. It has conducted in-person seminars every year to cultivate the knowledge necessary for practicing advanced cancer medicine. Owing to the coronavirus disease (COVID-19) pandemic, the society was obligated to conduct a web-based seminar this year. A questionnaire survey was conducted before and after the webinar to explain how it works and to assess the learning attitudes of beginner and moderately skilled pharmacists in the field of oncology. Questionnaire surveys were conducted with the participants before and after watching the webinar. The questionnaires sought to determine participants' perspectives on the webinar and their knowledge of the seven modules. Of the 1756 webinar attendees, 1661 (94.6%) answered the pre-webinar survey and 1586 (90.3%) answered the post-webinar survey. Results indicate that the median post-webinar knowledge score was significantly higher than the median pre-webinar score (p < 0.001) in all modules. Principal component analysis of the degree of knowledge of seven modules revealed that the improved score group consisted of those from younger age groups, with less experience as pharmacists, non-society members, and those with less experience in past society seminars. Moreover, the web-based seminar provided a uniform learning effect throughout the country without distinguishing between urban and rural learners. The web-based educational program was an acceptable educational tool for Japanese oncology pharmacists.

Abstract
Abstract
Study question
Does letrozole-induced endometrial preparation affect pregnancy outcomes, perinatal outcomes, and congenital anomalies after single vitrified-warmed blastocyst transfers (SVBTs) when compared with the natural cycle?
Summary answer
Letrozole-induced endometrial preparation improved live birth rate without any adverse effects on perinatal outcomes and congenital anomalies after SVBTs.
What is known already
Letrozole treatment is considered an effective option in endometrial preparation for frozen embryo transfers in patients with ovulation disorders or irregular menstruation; however, the effectiveness of letrozole-induced endometrial preparation is still unclear in ovulatory patients. Furthermore, there is no comparative study reporting on pregnancy complications and congenital anomalies after frozen embryo transfers comparing natural and letrozole-assisted cycles.
Study design, size, duration
This retrospective study, at a major academic fertility centre, analysed a total of 14,611 clinical records of women who underwent SVBTs comprising both natural and letrozole-assisted cycles between July 2015 and June 2020. The cycle characteristics, pregnancy outcomes (clinical pregnancy, ongoing pregnancy, and live birth), and the incidence of pregnancy complications and congenital anomalies were statistically compared between the natural and letrozole groups.
Participants/materials, setting, methods
The study reviewed ovulatory patients who underwent their first SVBT during the study period. Some patients took letrozole during the early proliferative phase to promote follicular development and maturation (letrozole group). Ovulation was triggered by GnRH agonist and SVBTs were performed on day five after ovulation. Propensity score matching was performed to reduce any bias from patient characteristics. Multivariate logistic analysis was performed to evaluate the effects of letrozole administration on pregnancy and perinatal outcomes.
Main results and the role of chance
After propensity score matching, the characteristics of patients and transferred blastocysts were comparable between groups. The serum progesterone level was also significantly increased in the letrozole group (P < 0.0001). Although no difference was observed regarding implantation rate between groups, the rates of clinical pregnancy, ongoing pregnancy, and delivery in the letrozole group were all significantly higher than that in the natural group (P = 0.0273, P = 0.0162, P = 0.0479, respectively). The incidence of early pregnancy loss, miscarriage, and stillbirth were comparable between groups. Multivariate logistic regression analysis also demonstrated that the administration of letrozole during an SVBT cycle significantly improved the live birth rate (AOR, 1.160; P = 0.0355). The incidence of pregnancy complications was comparable between groups. The caesarean section rate was significantly lower in the letrozole group than that in the natural group (P = 0.0464). Gestational age, birth length, birth weight, and infant sex, as well as the incidence of pregnancy complications and birth defects, were statistically comparable between groups. Furthermore, multivariate logistic regression analysis showed that perinatal outcomes were not affected by letrozole-induced endometrial preparation, although the incidence of caesarean section was decreased in the letrozole group (AOR, 0.788; P = 0.0355).
Limitations, reasons for caution
Our findings are not compared with reported incidences of pregnancy complications and congenital anomalies in natural pregnancy. Furthermore, the study was retrospective in nature, and further multicentre studies are required to ascertain the generalisability of these findings for other clinics with different protocols and/or patient demographics.
Wider implications of the findings
Letrozole administration both extended the proliferative phase and increased luteal function, resulting in an improvement of live birth rates without any adverse effects. Therefore, letrozole-induced endometrial preparation might be a safe and more effective strategy for patients with shortened proliferative phase or insufficient luteal function.

Abstract
Conditioned flavor preference (CFP) is established by association: where a neutral flavor (conditioned stimulus, CS) is paired with orosensory and post-ingestive components of nutrients, including sugar and fat (unconditioned stimulus, US). A previous study reported that rats can learn to prefer flavors that they consumed earlier and later in a multi-flavored solution paired with an intragastric infusion of glucose, but they expressed only a preference for a late-consumed flavor when they were tested after feeding (Myers and Whitney, 2011). This paradigm can be a suitable rodent model to explain how humans acquire a selective preference for routinely late-served "dessert" foods and why these foods remain attractive even in the absence of hunger. Here, we examined whether oral glucose (Experiment 1) or fat (Experiment 2) acts as a US for flavor preference learning processes in this paradigm. In Experiment 1, adult female rats under food restriction were trained in 16 daily sessions with two distinct flavor CSs in succession per session; eight CS(+) sessions in which two distinct flavor CSs (early(+), late(+)) were sequentially presented for 8 min each with oral glucose (12%) as a US, and eight CS(-) sessions in which different CSs (early(-), late(-)) were unpaired with the US. In the 30-minute two-bottle choice test, rats preferred late(+) over late(-) only when tested 90 min after consumption of normal chow (fed test) but not after overnight deprivation (hungry test). Early(+) was not preferred over early(-) in both tests. Moreover, a significant preference for late(+) over early(+) was observed only in the fed test, which is a unique feature of oral glucose-CFP. These results indicate that taste sensations of oral glucose promote a rewarding effect of late-onset glucose nutrients. In Experiment 2, separate rats were trained with the same conditioning paradigm, but used a caloric matched fat solution (5.3% corn oil) for a US. The results showed that they expressed stronger preferences for early(+) and late(+) relative to their respective CS(-) flavors in both tests. Similar to Experiment 1, it was observed in the fed test that there was a preference for late(+) over early(+) in oral fat-CFP. Taken together, the present results suggest that routine timing arrangements can cause qualitative differences in conditioned preferences between multiple flavors within a sugar or fat-containing meal in rats, and that rats prefer the late-consumed flavor over the early-consumed flavor in the absence of hunger.

Abstract
AIMS Cardiac rehabilitation (CR) is an evidence-based, secondary preventive strategy that improves mortality and morbidity rates in patients with heart failure (HF). However, the implementation and continuation of CR remains unsatisfactory, particularly for outpatients with physical frailty. This study investigated the efficacy and safety of a comprehensive home-based cardiac rehabilitation (HBCR) programme that combines patient education, exercise guidance, and nutritional guidance using information and communication technology (ICT). METHODS AND RESULTS This study was a single-centre, open-label, randomized, controlled trial. Between April 2020 and November 2020, 30 outpatients with chronic HF (New York Heart Association II-III) and physical frailty were enrolled. The control group (n = 15) continued with standard care, while the HBCR group (n = 15) also received comprehensive, individualized CR, including ICT-based exercise and nutrition guidance using ICT via a Fitbit® device for 3 months. The CR team communicated with each patient in HBCR group once a week via the application messaging tool and planned the training frequency and intensity of training individually for the next week according to each patient's symptoms and recorded pulse data during exercise. Dietitians conducted a nutritional assessment and then provided individual nutritional advice using the picture-posting function of the application. The primary outcome was the change in the 6 min walking distance (6MWD). The participants' mean age was 63.7 ± 10.1 years, 53% were male, and 87% had non-ischaemic heart disease. The observed change in the 6MWD was significantly greater in the HBCR group (52.1 ± 43.9 m vs. -4.3 ± 38.8 m; P < 0.001) at a 73% of adherence rate. There was no significant change in adverse events in either group. CONCLUSIONS Our comprehensive HBCR programme using ICT for HF patients with physical frailty improved exercise tolerance and improved lower extremity muscle strength in our sample, suggesting management with individualized ICT-based programmes as a safe and effective approach. Considering the increasing number of HF patients with frailty worldwide, our approach provides an efficient method to keep patients engaged in physical activity in their daily life.

Abstract
Renal denervation is a promising new non-pharmacological treatment for resistant hypertension. However, there is a lack of data from Asian patients. The REQUIRE trial investigated the blood pressure-lowering efficacy of renal denervation in treated patients with resistant hypertension from Japan and South Korea. Adults with resistant hypertension (seated office blood pressure ≥150/90 mmHg and 24-hour ambulatory systolic blood pressure ≥140 mmHg) with suitable renal artery anatomy were randomized to ultrasound renal denervation or a sham procedure. The primary endpoint was change from baseline in 24-hour ambulatory systolic blood pressure at 3 months. A total of 143 patients were included (72 renal denervation, 71 sham control). Reduction from baseline in 24-hour ambulatory systolic blood pressure at 3 months was not significantly different between the renal denervation (-6.6 mmHg) and sham control (-6.5 mmHg) groups (difference: -0.1, 95% confidence interval -5.5, 5.3; p = 0.971). Reductions from baseline in home and office systolic blood pressure (differences: -1.8 mmHg [p = 0.488] and -2.0 mmHg [p = 0.511], respectively), and medication load, did not differ significantly between the two groups. The procedure-/device-related major adverse events was not seen. This study did not show a significant difference in ambulatory blood pressure reductions between renal denervation and a sham procedure in treated patients with resistant hypertension. Although blood pressure reduction after renal denervation was similar to other sham-controlled studies, the sham group in this study showed much greater reduction. This unexpected blood pressure reduction in the sham control group highlights study design issues that will be addressed in a new trial.

Abstract
Intensive lipid-lowering therapy is recommended in individuals exhibiting type 2 diabetes mellitus (T2DM) with microvascular complications (as high-risk patients), even without known cardiovascular disease (CVD). However, evidence is insufficient to stratify the patients who would benefit from intensive therapy among them. Hypertension is a major risk factor, and uncontrolled blood pressure (BP) is associated with increased CVD risk. We evaluated the efficacy of intensive vs. standard statin therapy for primary CVD prevention among T2DM patients with retinopathy stratified by BP levels. We used the dataset from the EMPATHY study, which compared intensive statin therapy targeting low-density lipoprotein cholesterol (LDL-C) levels of <70 mg/dL and standard therapy targeting LDL-C levels ranging from ≥100 to <120 mg/dL in T2DM patients with retinopathy without known CVD. A total of 4980 patients were divided into BP ≥ 130/80 mmHg (systolic BP ≥ 130 mmHg and/or diastolic BP ≥ 80 mmHg, n = 3335) and BP < 130/80 mmHg (n = 1645) subgroups by baseline BP levels. During the median follow-up of 36.8 months, 281 CVD events were observed. Consistent with previous studies, CVD events occurred more frequently in the BP ≥ 130/80 mmHg subgroup than in the BP < 130/80 mmHg subgroup (P < 0.001). In the BP ≥ 130/80 mmHg subgroup, intensive statin therapy was associated with lower CVD risk (HR 0.70, P = 0.015) than standard therapy after adjustment. No such association was observed in the BP < 130/80 mmHg subgroup. The interaction between BP subgroup and statin therapy was significant. In conclusion, intensive statin therapy targeting LDL-C < 70 mg/dL provided benefits in primary CVD prevention when compared with standard therapy among T2DM patients with retinopathy and BP ≥ 130/80 mmHg.

Abstract
WHAT IS KNOWN AND OBJECTIVE Continuing education is essential for pharmacists to acquire and maintain the knowledge, skills, and ethical attitudes necessary for clinical practice. However, with the emergence of COVID-19, the social circumstances and face-to-face learning environments have changed. The objectives of this study were to determine Japanese pharmacists' perception of a web-based educational programme in oncology, and assess changes in their understanding of pharmaceutical care in oncology before and after their participation in the webinar. METHODS Questionnaire-based surveys were conducted for the participants of the web-based educational programme to determine their perspectives on the webinar, and their degree of comprehension of the five cancer types covered before and after watching the webinar. RESULTS AND DISCUSSION Of the 1936 pharmacists taking the programme, all participated in the pre-webinar survey, and 1861 (96.1%) in the post-webinar survey. Compared with previous seminars that were held in the offline mode before the COVID-19 pandemic, 76.8% of respondents were significantly satisfied with the web-based educational programme. The median post-webinar comprehension scores in all modules were significantly higher than the median pre-webinar scores (p < 0.0001). A majority of the participants agreed that a web-based educational programme was satisfactory in acquiring knowledge. WHAT IS NEW AND CONCLUSION This web-based educational programme was effective for Japanese pharmacists for postgraduate education in pharmaceutical care in oncology. To the best of our knowledge, our study is the first to report the effectiveness of a web-based educational programme for oncology pharmacists using a large population.

Abstract
A 61-year-old woman suffered chest pain and was admitted to a nearby hospital emergency department. She was diagnosed with acute myocardial infarction probably due to thromboembolism in the left anterior descending coronary artery and aspiration thrombectomy was performed. Afterwards, she developed refractory heart failure with severe global left ventricular dysfunction and was transferred to our hospital. An 18F-FDG-PET/CT scan revealed abnormal 18F-FDG uptake in non-infarcted regions of the left ventricle. Non-caseating granulomas were detected by biopsy from a skin eruption. She was diagnosed with cardiac sarcoidosis. In cases of refractory heart failure which cannot be explained only by myocardial infarction, evaluation of other undiagnosed cardiomyopathies is important for optimal management.

Abstract
Food neophobia is a behavior observed in rodents involving reduced consumption of a novel food or drink. In the absence of negative post-ingestive consequences, consumption increases with exposure (attenuation of neophobia), which is seen as an associative safe memory. Olfaction and gustation are sensory modalities essential for the development of a food preference. However, little is known about the neural mechanisms underlying neophobia to a food-related odor stimulus. In the present study, we examined the effect of pharmacological inactivation of the ventral hippocampus (vHPC) on neophobia to orally consumed solutions in rats using muscimol, a gamma aminobutyric acid type A receptor agonist. Two different types of solutions, almond odor (benzaldehyde) and sweet taste (saccharin), were prepared. In the results, microinjections of muscimol into the bilateral vHPC before the first odor and taste exposures did not alter the neophobic reactions of the rats to each stimulus. However, in the second odor, but not taste, exposure, the muscimol-injected rats showed higher consumption in comparison to that observed in the control rats, suggesting that the vHPC inactivation facilitates the attenuation of odor neophobia. On the other hand, intra-vHPC muscimol microinjections after the first odor and taste exposures did not facilitate consumption at the second exposures. These results indicate that neural activations within vHPC during orally consuming a novel odor, but not taste, solution play an inhibitory role in the subsequent attenuation of neophobia.

Abstract
Materials and structures of a collimator for a new neutron emission profile monitor in JT-60SA are examined through Monte Carlo simulations using the Monte Carlo N-Particle transport code. First, the shielding properties of various material combinations are compared in order to determine a combination with high shielding performances against both neutrons and gamma-rays. It is found that a collimator consisting of borated polyethylene and lead has a high shielding performance against neutrons. Moreover, a high shielding performance against gamma-rays is obtained when a lead pipe with a radial thickness of 0.01 m is inserted into a collimation tube. Second, we demonstrate that it is possible to improve the spatial resolution to a desired level by installing a thin tubular extension structure that fits into the limited space available between the main collimator block and the tokamak device. Finally, the collimator structures that meet both the targeted spatial resolutions (<10% of the plasma minor radius) and the targeted counting rate (105 cps order) are discussed.

Abstract
Introduction:
Control of blood pressure (BP) is associated with decreased risk of cardiovascular (CV) events in patients with type 2 diabetes mellitus (T2DM). Lowering the level of low-density lipoprotein cholesterol (LDL-C) by statins is also effective to reduce CV events in T2DM patients with hyperlipidemia. In this study, we examined whether the effectiveness of statin lipid-lowering therapy was affected by baseline BP level in T2DM patients in a primary prevention setting.
Methods:
The EMPATHY study was a randomized controlled trial investigating the effects of statin intensive therapy targeting LDL-C <70 mg/dL compared to standard therapy targeting LDL-C ≥100 to <120 mg/dL in T2DM patients with diabetic retinopathy and hyperlipidemia without known CV diseases. In this post-hoc subgroup analysis, a total of 4980 patients were divided into two groups based on baseline BP: high BP (systolic BP ≥130 mmHg and/or diastolic BP ≥80 mmHg) and non-high BP (systolic BP <130 mmHg and diastolic BP <80 mmHg) groups. CV events were defined as composite of cardiac, cerebral, renal, and vascular events.
Results:
At baseline, mean systolic and diastolic BP values were 141.7 and 78.3 mmHg in high BP group (n=3335) and 120.2 and 67.9 mmHg in non-high BP group (n=1645). Compared to non-high BP group, the proportion of patients with diabetic nephropathy (55.5 % vs 46.6 %), body mass index (26.1 kg/m
2
vs 24.8 kg/m
2
), HbA1c (7.82 % vs 7.67 %), and LDL-C (131.3 mg/dL vs 129.6 mg/dL) were significantly higher in high BP group. During a median follow-up of 36.8 months, 281 CV events were observed. In high BP group, statin intensive therapy was associated with low risk of CV events (HR 0.70, 95% CI 0.54-0.92, p=0.011) compared to standard therapy after adjustment. In non-high BP group, no such association was observed. Interaction between BP group and statin therapy was significant in CV events (p=0.036).
Conclusion:
Compared to statin standard therapy, statin intensive therapy targeting LDL-C <70 mg/dL significantly reduced CV events in the primary prevention setting among T2DM patients with BP ≥130/80 mmHg, but not among those with BP <130/80 mmHg.

Abstract
Nox4 (NADPH [Nicotinamide adenine dinucleotide phosphate] oxidase 4) is a major source of oxidative stress and is intimately involved in cardiac hypertrophy. DPP (Dipeptidyl peptidase)-4 inhibitor has been reported to regulate Nox4 expression in adipose tissues. However, its effects on Nox4 in cardiac hypertrophy are still unclear. We investigated whether DPP-4 inhibitor could ameliorate cardiac hypertrophy by regulating Nox4 and its downstream targets. Ang II (Angiotensin II; 1.44 mg/kg per day) or saline was continuously infused into C57BL/6J mice with or without teneligliptin (a DPP-4 inhibitor, 30 mg/kg per day) in the drinking water for 1 week. Teneligliptin significantly suppressed plasma DPP-4 activity without any significant changing aortic blood pressure or metabolic parameters such as blood glucose and insulin levels. It attenuated Ang II-induced increases in left ventricular wall thickness and the ratio of heart weight to body weight. It also significantly suppressed Ang II-induced increases in Nox4 mRNA, 4-hydroxy-2-nonenal, and phosphorylation of HDAC4 (histone deacetylase 4), a downstream target of Nox4 and a crucial suppressor of cardiac hypertrophy, in the heart. Exendin-3 (150 pmol/kg per minute), a GLP-1 (glucagon-like peptide 1) receptor antagonist, abrogated these inhibitory effects of teneligliptin on Nox4, 4-hydroxy-2-nonenal, phosphorylation of HDAC4, and cardiac hypertrophy. In cultured neonatal cardiomyocytes, exendin-4 (100 nmol/L, 24 hours), a GLP-1 receptor agonist, ameliorated Ang II-induced cardiomyocyte hypertrophy and decreased in Nox4, 4-hydroxy-2-nonenal, and phosphorylation of HDAC4. Furthermore, exendin-4 prevented Ang II-induced decrease in nuclear HDAC4 in cardiomyocytes. In conclusion, GLP-1 receptor stimulation by DPP-4 inhibitor can attenuate Ang II-induced cardiac hypertrophy by suppressing of the Nox4-HDAC4 axis in cardiomyocytes.

Abstract
Soft X-ray spectromicroscopy was applied to study the quantitative distribution of DNA and protein in a mammalian chromosome at the spatial resolution of 100 nm. The quantities of DNA and protein were evaluated using 1s-π* transition in the NEXAFS spectra at the nitrogen K absorption edge. DNA was not uniformly distributed in the chromosome and DNA/protein ratio was less than 0.497. The present analysis revealed the clues to identify other molecules that contribute to the absorption spectrum of the sample. The results suggested that accumulation of the absorption spectra of relevant molecules would support the refinement of the analysis.

Abstract
OBJECTIVE The role of baseline severity as effect modifier in various psychiatric disorders is a topic of controversy and of clinical import. This study aims to examine whether baseline severity modifies the efficacy of various antidepressants for major depression through individual participant data (IPD) meta-analysis. METHOD We identified all placebo-controlled, double-blind randomised trials of new generation antidepressants in the acute phase treatment of major depression conducted in Japan and requested their IPD through the public-private partnerships (PPPs) between the relevant academic societies and the pharmaceutical companies. The effect modification by baseline depression severity was examined through six increasingly complex competing mixed-effects models for repeated measures. RESULTS We identified eleven eligible trials and obtained IPD from six, which compared duloxetine, escitalopram, mirtazapine, paroxetine or bupropion against placebo (total n = 2464). The best-fitting model revealed that the interaction between baseline severity and treatment was not statistically significant (coefficient = -0.04, 95% confidence interval: -0.16 to 0.08, P = 0.49). Several sensitivity analyses confirmed the robustness of the findings. CONCLUSION We may expect as much benefit from antidepressant treatments for mild, moderate or severe major depression. Clinical practice guidelines will need to take these findings into consideration.

Abstract
While it has been shown that the blockade of N-methyl-d-aspartate type glutamate receptors (NMDARs) impairs memory acquisition, recent studies have reported that the post-acquisition administration of NMDAR antagonists suppresses spatial memory decay. These findings suggest that NMDARs are important not only for the acquisition of new memories but also for the decay of previously acquired memories. The present study investigated the contributions of specific NMDAR subunits to spatial memory decay using NVP-AAM077 (NVP), an NMDAR antagonist that preferentially binds to GluN2A subunits, and the selective GluN2B blocker Ro 25-6981 (Ro). Following Morris water maze training (four trials/day for four days), NVP and/or Ro were subchronically infused into the rat hippocampus for five days. Seven days after training, NVP-treated rats and NVP/Ro-treated rats explored the target area significantly more than the control and Ro-treated rats. These results demonstrate that post-acquisition treatment with NVP, but not Ro, suppresses the forgetting of previously acquired spatial memories. The NVP-treated rats more persistently explored the target area in the second test, which was conducted one day after the first, while the NVP/Ro-treated rats did not, which suggest that Ro treatment downregulates memory retention. In conclusion, the present results indicate that the NMDAR GluN2A and GluN2B subunits contribute to spatial memory deterioration and maintenance, respectively.
