Abstract
BACKGROUND Less than 50% of non-Hispanic Asian adults taking antihypertensive medication have controlled blood pressure. METHODS We compared non-persistence and low adherence to antihypertensive medication between non-Hispanic Asian and other race/ethnicity groups among US adults ≥66 years who initiated antihypertensive medication between 2011 and 2018 using a 5% random sample of Medicare beneficiaries (non-Hispanic Asian, n = 2,260; non-Hispanic White, n = 56,000; non-Hispanic Black, n = 5,792; Hispanic, n = 4,212; and Other, n = 1,423). Non-persistence was defined as not having antihypertensive medication available to take in the last 90 of 365 days following treatment initiation. Low adherence was defined as having antihypertensive medication available to take on <80% of the 365 days following initiation. RESULTS In 2011-2012, 2013-2014, 2015-2016 and 2017-2018, the proportion of non-Hispanic Asian Medicare beneficiaries with non-persistence was 29.1%, 25.6%, 25.4% and 26.7% (p-trend = 0.381), respectively, and the proportion with low adherence was 58.1%, 54.2%, 53.4% and 51.6%, respectively (p-trend = 0.020). In 2017-2018, compared with non-Hispanic Asian beneficiaries, non-persistence was less common among non-Hispanic White beneficiaries (risk ratio 0.74 [95%CI, 0.64-0.85]), non-Hispanic Black beneficiaries (0.80 [95%CI 0.68-0.94]) and those reporting Other race/ethnicity (0.68 [95%CI, 0.54-0.85]) but not among Hispanic beneficiaries (1.04 [95%CI, 0.88-1.23]). Compared to non-Hispanic Asian beneficiaries, non-Hispanic White beneficiaries and beneficiaries reporting Other race/ethnicity were less likely to have low adherence to antihypertensive medication (relative risk 0.78 [95%CI 0.72-0.84] and 0.84 [95%CI 0.74-0.95], respectively); there was no association for non-Hispanic Black or Hispanic beneficiaries. CONCLUSIONS Non-persistence and low adherence to antihypertensive medication were more common among older non-Hispanic Asian than non-Hispanic White adults.

Abstract
Neocortical slow waves are critical for memory consolidation. The retrosplenial cortex is thought to facilitate the slow wave propagation to regions beyond the neocortex. However, it remains unclear which population is responsible for the slow wave propagation. To address this issue, we performed in vivo whole-cell recordings to identify neurons that were synchronous and asynchronous with slow waves. By quantifying their intrinsic membrane properties, we observed that the former exhibited regular spiking, whereas the latter exhibited late spiking. Thus, these two cell types transmit information in different directions between the neocortex and subcortical regions.

Abstract
BACKGROUND Using high awake blood pressure (BP; ≥130/80 mm Hg) on ambulatory BP monitoring (ABPM) as a reference, the purpose of this study was to determine the accuracy of high office BP (≥130/80 mm Hg) at an initial visit and high confirmatory office BP (≥130/80 mm Hg), and separately, high home BP (≥130/80 mm Hg) among participants with high office BP (≥130/80 mm Hg) at an initial office visit. METHODS AND RESULTS The accuracy of office BP measurements using the oscillometric method for detecting high BP on ABPM was determined among 379 participants with complete office BP and ABPM data in the IDH (Improving the Detection of Hypertension) study. For detecting high BP on ABPM, the accuracy of high confirmatory office BP using the oscillometric method and, separately, high home BP was also determined among the subgroup of 122 participants with high office BP at an initial visit and complete home BP monitoring data. High office BP had moderate sensitivity (0.61 [95% CI, 0.53-0.68]) and high specificity (0.85 [95% CI, 0.80-0.90]) for high awake BP. High confirmatory office BP and high home BP had moderate sensitivity (0.69 [95% CI, 0.59-0.79] and 0.79 [95% CI, 0.71-0.87], respectively) and low and moderate specificity (0.44 [95% CI, 0.27-0.61] and 0.72 [95% CI, 0.56-0.88], respectively). CONCLUSIONS Many individuals with high BP on ABPM do not have high office BP. Confirmatory office BP and home blood pressure monitoring also had limited ability to identify individuals with high BP on ABPM.

Abstract
BACKGROUND Blood pressure (BP) thresholds for diagnosing and managing hypertension vary for office, home, and ambulatory readings, and between guideline documents. This analysis determined corresponding office, home, and ambulatory BP thresholds using baseline data from the HI-JAMP (Home-Activity Information and Communication Technology-Based Japan Ambulatory Blood Pressure Monitoring Prospective) study, which used a validated "all-in-one" BP monitoring device. METHODS AND RESULTS Data from 2322 treated patients with hypertension who underwent office BP measurement, then 24-hour ambulatory BP monitoring, then home BP monitoring for 5 days were analyzed. Corresponding BP thresholds for office, home, and ambulatory measurements were determined using Deming regression. Values equivalent to office systolic BP (SBP) of 120 and 140 mm Hg were as follows: 115.9 and 127.7 mm Hg for 24-hour ambulatory SBP; 120.8 and 134.0 mm Hg for daytime ambulatory SBP; 104.9 and 117.9 mm Hg for nighttime ambulatory SBP; and 122.0 and 134.2 mm Hg for morning-evening average home SBP. Deming regression showed that morning-evening average home SBP and daytime ambulatory SBP were almost the same (home SBP=0.99×daytime ambulatory SBP+0.27 mm Hg; r=0.627). Morning-evening average home SBP values of 120 and 135 mm Hg were equivalent to daytime ambulatory SBP values of 119.1 and 133.9 mm Hg, respectively. A home SBP threshold of 130 mm Hg corresponded to 24-hour and nighttime ambulatory SBP values of 123.5 and 113.6 mm Hg, whereas a home SBP threshold of 135 mm Hg corresponded to 24-hour and nighttime ambulatory SBP values of 128.0 and 119.2 mm Hg. CONCLUSIONS Ambulatory and home BP thresholds in this analysis were similar to those proposed by existing guidelines. The similarity between the home BP and daytime ambulatory BP thresholds was a clinically relevant finding.

Abstract
This article proposes a method for an artificial agent to behave in a social manner. Although defining proper social behavior is difficult because it differs from situation to situation, the agent following the proposed method adaptively behaves appropriately in each situation by empathizing with the surrounding others. The proposed method is achieved by incorporating empathy into active inference. We evaluated the proposed method regarding control of autonomous mobile robots in diverse situations. From the evaluation results, an agent controlled by the proposed method could behave more adaptively socially than an agent controlled by the standard active inference in the diverse situations. In the case of two agents, the agent controlled with the proposed method behaved in a social way that reduced the other agent's travel distance by 13.7% and increased the margin between the agents by 25.8%, even though it increased the agent's travel distance by 8.2%. Also, the agent controlled with the proposed method behaved more socially when it was surrounded by altruistic others but less socially when it was surrounded by selfish others.

Abstract
BACKGROUND Home blood pressure (BP) is an important component of digital strategies for hypertension management. However, no studies have used the same device to investigate 24-hour BP control status in relation to different home BP control thresholds. METHODS Participants in the general practitioner-based, multicenter HI-JAMP study (Home-Activity Information and Communication Technology-Based Japan Ambulatory Blood Pressure Monitoring Prospective) underwent office BP measurement, then 24-hour ambulatory BP monitoring, then home BP monitoring for 5 days. A validated all-in-one BP monitoring device was used to measure office, home, and ambulatory BP. Baseline data were used to investigate ambulatory BP control status in individuals with well-controlled home BP based on the different guideline thresholds (125/75 mm Hg, 130/80 mm Hg, and 135/85 mm Hg). RESULTS Data from 2269 patients were analyzed. For individuals with well-controlled home BP <135/85 mm Hg (59.5% of the total population), the prevalence of uncontrolled 24-hour (≥130/80 mm Hg), daytime (≥135/85 mm Hg), and nighttime ambulatory BP (≥120/70 mm Hg) was 19.9%, 18.5%, and 33.6%, respectively. Corresponding prevalence rates in the 42.7% of participants with well-controlled home BP <130/80 mm Hg were 13.4%, 12.9%, and 26.0%, and when well-controlled home BP was strictly defined as <125/75 mm Hg (23.9% of the population), prevalence of rates of uncontrolled 24-hour, daytime, and nighttime ambulatory BP were 7.0%, 9.0%, and 15.3%, respectively. CONCLUSIONS Home BP control status defined using different thresholds could predict 24-hour ambulatory BP control status in treated hypertension. One-third of individuals still had uncontrolled nocturnal hypertension when home BP was controlled to <135/85 mm Hg, but ambulatory BP was quite well controlled when home BP was <125/75 mm Hg.

Abstract
BACKGROUND Home blood pressure (BP) monitoring over a 7-day period is recommended to confirm the diagnosis of hypertension. METHODS We determined upper and lower home BP thresholds with >90% positive predictive value and >90% negative predictive value using 1 to 6 days of monitoring to identify high home BP (systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg) based on 7 days of home BP monitoring. The sample included 361 adults from the Improving the Detection of Hypertension Study who were not taking antihypertensive medication. We used two 7-day periods, at least 3 days apart, the first being a sampling period and the second a reference period. For each number of days in the sampling period, we determined the percentage of participants who had a high likelihood of having (>90% positive predictive value) or not having (>90% negative predictive value) high BP and would not need to continue home BP monitoring. Only the participants in an uncertain category (ie, positive predictive value ≤90% and negative predictive value ≤90%) after each day were carried forward to the next day of home BP monitoring. RESULTS Of the 361 participants (mean [SD] age of 41.3 [13.2] years; 60.4% women), 38.0% had high home BP during the reference period. There were 63.7%, 17.1%, 10.5%, 3.3%, 3.6%, and 1.4% participants who would not need to continue after 1, 2, 3, 4, 5, and 6 days of monitoring. CONCLUSIONS In most people, high home BP can be identified or excluded with a high degree of confidence with 3 days or less of monitoring.

Abstract
Introduction In recent years, the widespread shift from on-site to remote work has led to a decline in employees' mental health. Consequently, this transition to remote work poses several challenges for both employees and employers. To address these challenges, there is an urgent need for techniques to detect declining mental health in employees' daily lives. Emotion-based health assessment, which examines emotional diversity (emodiversity) experienced in daily life, is a possible solution. However, the feasibility of emodiversity remains unclear, especially from the perspectives of its applicability to remote workers and countries other than Europe and the United States. This study investigated the association between subjective mental health decline and emotional factors, such as emodiversity, as well as physical conditions, in remote workers in Japan. Method To explore this association, we conducted a consecutive 14-day prospective observational experiment on 18 Japanese remote workers. This experiment comprised pre-and post-questionnaire surveys, physiological sensing, daytime emotion self-reports, and subjective health reports at end-of-day. In daytime emotion self-reports, we introduced smartphone-based experience sampling (also known as ecological momentary assessment), which is suitable for collecting context-dependent self-reports precisely in a recall bias-less manner. For 17 eligible participants (mean ± SD, 39.1 ± 9.1 years), we evaluated whether and how the psycho-physical characteristics, including emodiversity, changed on subjective mental health-declined experimental days after analyzing descriptive statistics. Results Approximately half of the experimental days (46.3 ± 18.9%) were conducted under remote work conditions. Our analysis showed that physical and emotional indices significantly decreased on mental health-declined days. Especially on high anxiety and depressive days, we found that emodiversity indicators significantly decreased (global emodiversity on anxiety conditions, 0.409 ± 0.173 vs. 0.366 ± 0.143, p = 0.041), and positive emotional experiences were significantly suppressed (61.5 ± 7.7 vs. 55.5 ± 6.4, p < 0.001). Discussion Our results indicated that the concept of emodiversity can be applicable even to Japanese remote workers, whose cultural background differs from that of individuals in Europe and the United States. Emodiversity showed significant associations with emotion dysregulation-related mental health deterioration, suggesting the potential of emodiversity as useful indicators in managing such mental health deterioration among remote workers.

Abstract
Background:
Chronic stress experienced at home or work has been associated with acute increases in blood pressure (BP) measured in the doctor’s office, but few data are available on the association of chronic stress with BP measured outside of the office setting.
Methods:
We analyzed data from 473 African-American adults enrolled in the Jackson Heart Study with office BP < 130/80 mm Hg to examine the association between chronic stress and masked hypertension (MHT). Chronic stress related to jobs, relationships, neighborhoods, caregiving, legal problems, medical problems, racism and discrimination, and meeting basic needs experienced over the previous 12 months was assessed using the 8-item Global Perceived Stress Scale (GPSS). We grouped participants by tertile of the composite GPSS score. Any MHT was defined as awake BP ≥ 130/80 mm Hg, asleep BP ≥ 110/65 mm Hg, or 24-hour BP ≥ 125/75 mm Hg. Analyses were stratified by antihypertensive medication use.
Results:
Among participants not taking antihypertensive medication (mean age 53 years), the prevalence of any MHT was 59.0%, 75.0% and 61.8% for the low (GPSS score ≤ 3), middle (GPSS score 4 - 6), and upper tertiles of the GPSS score (GPSS score > 6), respectively. Among those taking antihypertensive medication (mean age 61 years), the prevalence of any MHT was 77.4%, 80.7%, and 77.9% for participants in the low, middle, and upper tertile of the GPSS score, respectively. After multivariable adjustment, the prevalence ratio (95% confidence interval) for any MHT associated with the middle and upper versus low tertile of the GPSS score was 1.23 (0.96, 1.57) and 1.07 (0.83, 1.39), respectively, among those not taking antihypertensive medication and 0.97 (0.82, 1.14) and 1.02 (0.85, 1.21), respectively, among those taking antihypertensive medication (Table).
Conclusion:
No association was present between chronic stress and MHT among African Americans in the Jackson Heart Study.

Abstract
BACKGROUND Inconsistencies between the office and out-of-office blood pressure (BP) values (described as white-coat hypertension or masked hypertension) may be attributable in part to differences in the BP monitoring devices used. METHODS We studied consistency in the classification of BP control (well-controlled BP vs. uncontrolled BP) among office, home, and ambulatory BPs by using a validated "all-in-one" BP monitoring device. In the nationwide, general practitioner-based multicenter HI-JAMP study, 2,322 hypertensive patients treated with antihypertensive drugs underwent office BP measurements and 24-hour ambulatory BP monitoring (ABPM), consecutively followed by 5-day home BP monitoring (HBPM), for a total of seven BP measurement days. RESULTS Using the thresholds of the JSH2019 and ESC2018 guidelines, the patients with consistent classification of well-controlled status in the office (<140 mmHg) and home systolic BP (SBP) (<135 mmHg) (n = 970) also tended to have well-controlled 24-hour SBP (<130 mmHg) (n = 808, 83.3%). The patients with the consistent classification of uncontrolled status in office and home SBP (n = 579) also tended to have uncontrolled 24-hour SBP (n = 444, 80.9%). Among the patients with inconsistent classifications of office and home BP control (n = 803), 46.1% had inconsistent ABPM-vs.-HBPM out-of-office BP control status. When the 2017 ACC/AHA thresholds were applied as an alternative, the results were essentially the same. CONCLUSIONS The combined assessment of the office and home BP is useful in clinical practice. Especially for patients whose office BP classification and home BP classification conflict, the complementary clinical use of both HBPM and ABPM might be recommended.

Abstract
BACKGROUND Non-dipper and riser patterns of nocturnal blood pressure (BP) are risk factors for cardiovascular disease (CVD), including heart failure (HF). However, the risk associated with a disrupted nocturnal pattern of heart rate is not well known. OBJECTIVES To investigate whether the nighttime heart rate is a risk factor for HF, alongside nighttime BP phenotype. METHODS The practitioner-based, nationwide, prospective Japan Ambulatory Blood Pressure Monitoring Prospective (JAMP) study included patients with ≥ 1 CVD risk factor but without symptomatic CVD at baseline. All patients underwent 24-h ambulatory BP monitoring at baseline and were followed annually. Nocturnal heart rate dipping (%) was calculated as 100•[1 - nighttime/daytime heart rate]. RESULTS During a mean 4.5 years' follow-up in 6,359 patients (mean age 68.6 years), there were 306 CVD events (119 stroke, 99 coronary artery disease, and 88 HF). A 10-beats/min increase in nighttime heart rate was significantly associated with a 36-47% increase in the risk of total CVD, stroke and HF events independently of office SBP and nighttime SBP (all p < 0.005). The CVD and HF risk associated with nocturnal heart rate dipping status was independent of office and 24-h systolic BP and nocturnal BP dipping status (p < 0.001). Performance of the final model for predicting HF including BP parameters was significantly improved by the addition of nocturnal heart rate dipping patterns (p = 0.038; C-statistic 0.852). CONCLUSION Nighttime non-dipper and riser patterns of heart rate were associated with CVD especially HF, independently and additively of nocturnal BP dipping status, indicating the importance of antihypertensive strategies targeting nighttime hemodynamics.

Abstract
Background Several treatments for traumatic facial paralysis have been reported, but the role of surgery is still controversial. Case Description A 57-year-old man was admitted to our hospital with head trauma due to a fall injury. A total body computed tomography (CT) scan showed a left frontal acute epidural hematoma associated with a left optic canal and petrous bone fractures with the disappearance of the light reflex. Hematoma removal and optic nerve decompression were performed immediately. The initial treatment was successful with complete recovery of consciousness and vision. The facial nerve paralysis (House and Brackmann scale grade 6) did not improve after medical therapy, and thus, surgical reconstruction was performed 3 months after the injury. The left hearing was lost entirely, and the facial nerve was surgically exposed from the internal auditory canal to the stylomastoid foramen through the translabyrinthine approach. The facial nerve's fracture line and damaged portion were recognized intraoperatively near the geniculate ganglion. The facial nerve was reconstructed using a greater auricular nerve graft. Functional recovery was observed at the 6-months follow-up (House and Brackmann grade 4), with significant recovery in the orbicularis oris muscle. Conclusion Interventions tend to be delayed, but it is possible to select a treatment method of the translabyrinthine approach.

Abstract
Objective Evaluation of intracranial stent placement by MRI suffers the problems of signal artifacts during time-of-flight MRA (TOF-MRA). Therefore, angiographic examination is required for detailed intravascular assessment of the stent placement site. Recently, 3D T1-turbo spin echo (3D-TSE) has been developed for evaluation of carotid artery stent placement. We investigated the use of the 3D-TSE imaging method for the evaluation of intracranial vascular stent placement. Methods The subjects consisted of nine patients who underwent intracranial vascular stent placement between April 2015 and December 2019. Postoperatively, the lumens of the placed stents were measured by TOF-MRA, DSA, and 3D-TSE imaging. Analysis was performed by type of stent and placement site. Results The stents used were Neuroform Atlas (3 patients), LVIS (3 patients), LVIS Jr (2 patients), and Integrity (1 patient). TOF-MRA of the stent placement site showed defects in the image or poor visualization in all nine patients, whereas 3D-TSE imaging visualized the lumen at the stent indwelling site in all patients. The blood vessel diameter measured by the DSA and 3D-TSE imaging exhibited positive correlations regardless of the stent type and placement site. Conclusion 3D-TSE imaging allows visualization of the lumen of the site of an intracranial vascular stent, regardless of the type of stent or the vessel. Thus, this method may be useful for evaluating the vascular lumen of a lesion.

Abstract
Abstract
Background
The effectiveness of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) has not been demonstrated in patients with heart failure with preserved ejection fraction (HFpEF). We recently reported significant interaction between the use of ACE-I and/or ARB (ACE-I/ARB) and frailty on prognosis in patients with HFpEF.
Purpose
In the present study, we examined the association between ACE-I/ARB and prognosis in patients with HFpEF stratified by the presence or absence of frailty.
Methods
We examined the association between the use of ACE-I/ARB and prognosis according to the presence (Clinical Frailty Scale (CFS) ≥5) or absence (CFS ≤4) of frailty in patients with HFpEF in a post-hoc analysis of registry data. Primary endpoint was the composite of all-cause mortality and heart failure admission. Secondary endpoints were all-cause mortality and heart failure admission.
Results
Of 1059 patients, median age was 83 years and 45% were male. Kaplan-Meier analysis showed that the risk of composite endpoint (log-rank P=0.001) and all-cause death (log-rank P=0.005) in patients with ACE-I/ARB was lower in those with CFS ≥5, but similar between patients with and without ACE-I/ARB in patients with CFS ≤4 (composite endpoint: log-rank P=0.830; all-cause death: log-rank P=0.192). In a multivariable Cox proportional hazards model, use of ACE-I/ARB was significantly associated with lower risk of the composite endpoint (hazard ratio = 0.52, 95% CI: 0.33–0.83, P=0.005) and heart failure admission (hazard ratio = 0.45, 95% CI: 0.25–0.83, P=0.010) in patients with CFS ≥5, but not in patients with CFS ≤4 (composite endpoint: hazard ratio = 1.41, 95% CI: 0.99–2.02, P=0.059; heart failure admission: hazard ratio = 1.43, 95% CI: 0.94–2.18, P=0.091). The association between ACE-I or ARB and prognosis did not significantly differ by CFS (CFS ≤4: log-rank P=0.562; CFS ≥5: log-rank P=0.100, for with ACE-I vs. ARB, respectively). Adjusted HRs for CFS 1–4 were higher than 1.0, but were less than 1.0 at CFS 5.
Conclusions
In patients with HFpEF, use of ACE-I/ARB was associated with better prognosis in patients with frailty as assessed with the CFS, but not in those without frailty.

Abstract
Abstract
Introduction
It is important to detect the recurrence of atrial fibrillation (AF) after catheter ablation (CA) early, but the method of detection has not been established. The purpose of this study is to determine whether 24-h Holter electrocardiogram (ECG) can predict the recurrence of AF after CA.
Methods
We studied 336 patients of 497 patients enrolled in EARNEST-PVI trial to investigate whether the total number of premature atrial contraction (PAC) and the maximum number of PAC run by 24-h Holter ECG at 6 months after CA predicted AF recurrence after 6 months. We excluded 86 patients with recurrence by 6 months after CA and 75 patients without Holter ECG at 6 months after CA.
Results
Median age was 66 years, male were 77% and median follow-up period was 1138 days. Receiver operating characteristic curve analysis identified the total number of PAC ≥270 beats and the maximum number of PAC run ≥8 beats as the optimal cutoff for prediction of AF recurrence. Kaplan-Meier analysis showed patients with the total number of PAC ≥270 beats had more frequent AF recurrence than those without (Kaplan-Meier estimated 3-year AF recurrence rate 34% vs. 17%, Log-rank P=0.001) and patients with the maximum number of PAC run ≥8 beats had more frequent AF recurrence than those without (Kaplan-Meier estimated 3-year AF recurrence rate 33% vs. 20%, Log-rank P=0.006). Multivariate analysis revealed that the total number of PAC ≥270 beats and the maximum number of PAC run were significantly associated with AF recurrence (hazard ratio [95% confidence interval] 1.83 [1.16–2.91], P=0.01 and 1.01 [1.01–1.02], P=0.001, respectively)
Conclusion
The total number of PAC and the maximum number of PAC run on the Holter ECG may be useful in predicting AF recurrence after CA.

Abstract
Background: Meningioma and dural arteriovenous fistula (dAVF) located at the same site are rare. The present case demonstrated the transformation of tumor feeding vessels into the pial feeder of the dAVF over time, which may help to elucidate the pathogenesis of tumor-associated dAVF. Case Description: A 71-year-old man presented with convulsion. Magnetic resonance (MR) imaging showed a right parasagittal sinus meningioma invading the superior sagittal sinus (SSS). Bilateral external carotid angiography showed dAVF at the SSS, near the site of tumor invasion. The right internal carotid angiography showed tumor staining from the anterior cerebral artery with intra-tumor arteriovenous shunting, with stagnation of tumor blood flow, suggesting impairment of perfusion to the SSS. Four years after the initial diagnosis, the patient was admitted to hospital with status epilepticus, and MR imaging showed an enlarged tumor. Carotid angiography revealed transformation of the tumor feeders to the pial feeder of the dAVF. The findings of shunting to the SSS had intensified, and stenosis had occurred in the posterior third of the SSS. The venous return showed retrograde flow anteriorly to the SSS. The patient underwent endovascular embolization and tumor resection. The shunt had disappeared. Conclusion: This report supports the proposal that impaired venous return is an important factor in the shunt occurrence of dAVF. Neurosurgeons should consider that cases of meningioma invading the venous sinuses may be complicated by dAVF and changes may occur over time.

Abstract
Accurate blood pressure (BP) measurement is necessary for the evaluation and treatment of hypertension to prevent the progression of subclinical vascular disease, including arterial stiffness. We investigated the associations between brachial-ankle pulse wave velocity (baPWV), a measure of arterial stiffness, and each of office brachial systolic BP (SBP) with and without an observer present (attended or unattended office brachial SBP), attended or unattended office central SBP, and home brachial SBPs (specifically, the means of morning, evening, or morning-evening home brachial SBP) in patients being treated for hypertension. Measurements were performed among 70 adults (mean age, 67.0 ± 9.4 years; women, 51.4%) with a mean attended office brachial SBP of 127.6 ± 14.5 mmHg and mean baPWV of 16.3 ± 2.8 m/s. Univariate analysis showed that higher attended office brachial SBP, morning home brachial SBP, and morning-evening home brachial SBP were each statistically significantly associated with higher baPWV (r = 0.25, P = 0.04; r = 0.37, P = 0.002; and r = 0.32, P = 0.006, respectively). Multiple linear regression analysis with adjustments for traditional cardiovascular risk factors showed that only morning home brachial SBP was statistically significantly associated with baPWV [β = 0.06, 95% confidence interval (0.01-0.11), P = 0.02). In conclusion, higher morning home brachial SBP - but none of the office-measured SBP values - was associated with arterial stiffness.

Abstract
Ferroptosis, a type of oxidative stress cell death, has been implicated in cell injury in several diseases, and treatments with specific inhibitors have been shown to protect cells and tissues. Here we demonstrated that a treatment with the nitroxide radical, 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO), prevented the ferroptotic cell death in an airborne manner. Other TEMPO derivatives and lipophilic antioxidants, such as Trolox and ferrostatin-1, also prevented cell death induced by erastin and RSL3; however, only TEMPO exhibited inhibitory activity from a physically distant location. TEMPO vaporized without decomposing, and then dissolved again into a nearby water solution. Volatilized TEMPO inhibited glutamate-induced cell death in mouse hippocampal cell lines, and also reduced neuronal cell death in a mouse ischemia model. These results suggest that TEMPO is a unique cell protective agent that acts in a volatility-mediated manner.

Abstract
Background The aim of this study was to investigate the association between night‐to‐night adherence to continuous positive airway pressure (CPAP) therapy and both home blood pressure (BP) level on the following day and seasonal variation in home BP in patients with obstructive sleep apnea. Methods and Results We analyzed 105 participants who had been diagnosed with obstructive sleep apnea (average apnea‐hypopnea index, 49.7±18.4 per hour) and who were already receiving CPAP therapy. Home BP (twice every morning and evening) and CPAP adherence data were automatically transmitted to a server for 1 year. A mixed‐effects model for repeated measures analysis was used to examine associations of night‐to‐night good CPAP adherence with day‐to‐day home BP within the same patient after adjusting for covariates. The average number of days in which patients achieved both CPAP adherence and morning or evening home BP measurement was 206.6±122.7 days (21 487 readings) and 191.2±126.3 days (20 170 readings), respectively. Good CPAP adherence (>4 hours per night of use) was achieved on the evening or morning before home BP measurements (86.8% and 86.9%, respectively). After adjustment for confounders, good CPAP adherence was negatively associated with morning home systolic BP (β, −0.663; P=0.004) and diastolic BP (β, −0.829; P<0.001). Morning home systolic BP in winter in the individuals with good CPAP adherence was significantly lower than that in individuals without such adherence (P<0.05). These associations were not found in evening home BP. Conclusions Good adherence to CPAP therapy was negatively associated with morning home BP on the following day in patients with obstructive sleep apnea. The association was remarkable in the winter season.

Abstract
BACKGROUND Autonomic dysreflexia (AD) is an abnormal reflex of the autonomic nervous system normally observed in patients with spinal cord injury from the sixth thoracic vertebra and above. AD causes various symptoms including paroxysmal hypertension due to stimulus. Here, we report a case of recurrent AD associated with cervical spinal cord tumor. CASE PRESENTATION The patient was a 57-year-old man. Magnetic resonance imaging revealed an intramedullary lesion in the C2, C6, and high Th12 levels. During the course of treatment, sudden loss of consciousness occurred together with abnormal paroxysmal hypertension, marked facial sweating, left upward conjugate gaze deviation, ankylosis of both upper and lower extremities, and mydriasis. Seizures repeatedly occurred, with symptoms disappearing after approximately 30 min. AD associated with cervical spinal cord tumor was diagnosed. Histological examination by tumor biopsy confirmed the diagnosis of gliofibroma. Radiotherapy was performed targeting the entire brain and spinal cord. The patient died approximately 3 months after treatment was started. CONCLUSIONS AD is rarely associated with spinal cord tumor, and this is the first case associated with cervical spinal cord gliofibroma. AD is important to recognize, since immediate and appropriate response is required.

Abstract
During behavioral states of immobility, sleep, and anesthesia, the hippocampus generates high-frequency oscillations called ripples. Ripples occur simultaneously with synchronous neuronal activity in the neocortex, known as slow waves, and contribute to memory consolidation. During these ripples, various neocortical regions exhibit modulations in spike rates and local field activity irrespective of whether they receive direct synaptic inputs from the hippocampus. However, little is known about the subthreshold dynamics of the membrane potentials of neocortical neurons during ripples. We patch-clamped layer 2/3 pyramidal cells in the posterior parietal cortex (PPC), a neocortical region that is involved in allocentric spatial representation of behavioral exploration and sequential series of relevant action potentials during ripples. We simultaneously monitored the membrane potentials of post hoc-identified PPC neurons and the local field potentials of the hippocampus in anesthetized mice. More than 50% of the recorded PPC neurons exhibited significant depolarizations and/or hyperpolarizations during ripples. Histological inspections of the recorded neurons revealed that the ripple-modulated PPC neurons were distributed in the PPC in a spatially non-biased fashion. These results suggest that hippocampal ripples are widely but selectively associated with the subthreshold dynamics of the membrane potentials of PPC neurons even though there is no monosynaptic connectivity between the hippocampus and the PPC.

Abstract
Supplemental Digital Content is available in the text. Ambulatory and home blood pressure (BP) monitoring parameters are better predictors of cardiovascular events than are office BP monitoring parameters, but there is a lack of robust data and little information on heart failure (HF) risk. The JAMP study (Japan Ambulatory Blood Pressure Monitoring Prospective) used the same ambulatory BP monitoring device, measurement schedule, and diary-based approach to data processing across all study centers and determined the association between both nocturnal hypertension and nighttime BP dipping patterns and the occurrence of cardiovascular events, including HF, in patients with hypertension.

Frailty is associated with malnutrition and poor prognosis in patients with heart failure with preserved ejection fraction (HFpEF). However, the cardiac factors associated with frailty have not been fully examined in patients with HFpEF.
Purpose
The purpose of this study is to clarify the cardiac factors related to frailty in patients with HFpEF.
Methods
Of the 756 patients who registered prospective, multicenter, observational study of patients with HFpEF (PURSUIT-HFpEF) registry, 481 cases with clinical frailty score (CFS) and prognosis after discharge were examined. Frailty was defined as CFS ≥5. Outcomes were composite endpoint of all-cause death and heart failure readmission, and all-cause mortality. We compared outcomes between patients without and with frailty, and sought to identify factors which were associated with increase in clinical frailty score by the correlation analysis and linear regression analysis.
Results
Of 481 patients, 131 patients (27.2%) were frail. Male gender was less in patients with frailty than those without frailty (26.7% vs 73.3%, P<0.001). Frail patients had higher age (85.2±7.3 vs 78.7±9.4 years, P<0.001). During follow-up period of 396 [343, 697] days, composite endpoint (Kaplan-Meier event rate estimates, 77% vs. 60%; log-rank P<0.001), and all-cause mortality (Kaplan-Meier event rate estimates, 57% vs. 28%; log-rank P<0.001) was higher in patients with frailty than those without frailty. Multivariate Cox regression analysis revealed frailty was significantly and independently associated with mortality (HR=1.40, 95% CI=1.17–1.68, P<0.001). CFS was significantly correlated with age (r=0.401, P<0.001), sex (r=0.223, P<0.001), body mass index (r=−0.146, P=0.001), hemoglobin (r=−0.148, P=0.001), albumin (r=−0.222, P<0.001), left ventricular diastolic diameter (r=−0.184, P<0.001), interventricular septum thickness (r=−0.124, P=0.008), left ventricular mass (r=−0.217, P<0.001), tricuspid annular plane systolic excursion (r=−0.165, P=0.001), and tricuspid regurgitation pressure gradient (TRPG) (r=0.189, P<0.001). Multivariate linear regression analysis using these factors as covariates revealed age (standardized β: 0.337, P<0.001), sex (standardized β: 0.120, P=0.014), albumin (standardized β: −0.151, P=0.003) and TRPG (standardized β: 0.129, P=0.005) were significantly and independently associated with increase in clinical frailty score.
Conclusion
Our results suggest that not only nutritional factors but also a cardiac factor were associated with frailty, and frailty was associated with mortality in patients with HFpEF. Improvement of hemodynamics in HFpEF patients as well as improvement of nutrition might contribute to alleviation of frail in HFpEF patients.

Abstract
Objective To prolong the health expectancy, it is important to prevent age-related diseases, such as osteoporosis and cerebrovascular disease, which are major causes of a bedridden state. Early predictable biomarkers for these diseases are urgently required in the clinical setting. Three members of the fibroblast growth factor (FGF) family - FGF19, FGF21, and FGF23 - are designated as endocrine FGFs and play crucial roles in various metabolic processes. We tried to clarify the clinical utility of endocrine FGFs as biomarkers for age-related diseases in elderly patients. Methods We examined the serum endocrine FGF levels and analyzed their association with various clinical parameters in 73 outpatients >60 years old as a single-center cross-sectional study. Results In a multivariable linear regression analysis, FGF19 was associated with ALT, a history of cardiovascular disease, and medication with active vitamin D3. FGF21 was associated with the estimated glomerular filtration rate (eGFR), triglyceride level, and hypertension. FGF23 was associated with the eGFR and the serum levels of 1,25-dihydroxy vitamin D3 and TRACP5b. In addition, a receiver operating characteristics analysis revealed that the measurement of FGF21 and FGF23 was useful for detecting chronic kidney disease (CKD) and its complications, including cardiovascular disease and metabolic bone disorder. Conclusion The measurement of FGF21 and FGF23 may be useful for evaluating CKD and its complications. Using serum endocrine FGFs as biomarkers for age-related conditions may help prevent elderly patients from entering a bedridden state.

Abstract
Focusing on the scalability of Two-Filter Method, we started to develop a monitor for the concentration of radon and its progeny. In this study, we investigated the influence of a high-humidity environment on measuring radon concentration, and the influence of the decay chamber of the monitor on the measurement. In the high-humidity test, the conversion factor of (Bqm-3)/(cpm) tends to raise with increasing humidity. On the measurement of radon progeny, existence of the decay chamber of the monitor makes measurement sensitivity lower under environments of little aerosols. Radon concentration measurement by the developed monitor could be influenced by environmental humidity, and that counting loss could occur due to deposition of radon progeny inside of the decay chamber. Correction relating these would be needed based on the data of calibration tests.

Abstract
After the Fukushima Daiichi Nuclear Power Plant accident, the radiation dose for first responders was not evaluated accurately due to lack of the monitoring data. It has been important to evaluate a radiation dose for workers in emergency response at a nuclear accident. In this study, a new device which can evaluate both of external and internal exposure doses was developed and the performance of various environmental radiation monitors including commercially available monitors were tested and compared from the viewpoint of an environmental monitoring at emergency situation. Background counts of the monitors and the ambient dose equivalent rate were measured in Fukushima Prefecture. The detection limit for beta particles was evaluated by the method of ISO11929. The sensitivity for gamma-rays of the dust monitor using a ZnS(Ag) and a plastic scintillator was high, but that of the external exposure monitor using a silicon photodiode with CsI(Tl) crystal was relatively low. The detection limit ranged 190-280 Bq m-3 at 100 μSv h-1, exceeding the detection limit of 100 Bq m-3 in the minimum requirement by the National Regulation Authority in Japan. Use of the shielding with lead is necessary to achieve the minimum requirement. These results indicate that the dust monitor using a ZnS(Ag) scintillator and a plastic scintillator is suitable for the external exposure monitor and the developed internal exposure monitor is for the internal exposure monitor at emergency situation among the evaluated monitors. In the future study, the counting efficiency, the relative uncertainty and the performance of the detection for alpha particles will be evaluated, and it will be considered which type of a monitor is suitable after taking the portability into account.

Abstract
Abstract
Background
It has been reported that intra-aortic balloon pumping (IABP) support for acute myocardial infarction (AMI) with cardiogenic shock did not reduce short and long-term mortality. However, the significance of IABP support for AMI patients with extracorporeal membrane oxygenation (ECMO) therapy remains unclear. The aim of this study was to investigate the effect of IABP support for the short and long-term outcome in AMI patients who received ECMO.
Methods
Using the database of the Osaka Acute Coronary Insufficiency Study (OACIS), 12,093 consecutive AMI patients were enrolled in this analysis. Among these, we analyzed 520 patients with ECMO. We classified the patients into two groups, patients who received IABP support [IABP group (n=460)] and patients who did not [no IABP group (n=60)]. Primary outcome was all-cause death.
Results
Study patients had following baseline clinical characteristics, age: 66.8±12.0 year old, male: 78.3%, diabetes mellitus: 41.0%, Killip class≥II: 66.2%, multi-vessel disease: 72.3%, peak creatine phosphokinase >3000IU/L: 68.1%. During a mean follow-up period of 349±625 days, Kaplan-Meier analysis revealed that the all-cause death was significantly lower in IABP group than no IABP group for 30-day (45.5% vs 72.7%, log-rank p<0.001) and long-term (66.2% vs 78.4%, Log rank p=0.005) follow-up period. Cox multivariate analysis revealed that IABP support was significantly associated with a reduced risk of mortality (Hazard ratio 0.445, 95% confidence interval 0.289 to 0.687, p<0.001).
Conclusions
IABP support for AMI patients with ECMO was significantly associated with reduced risks of the short and long-term mortality, suggesting that IABP support might contribute to improvement of the survival in AMI patients with ECMO.

Abstract
Abstract
Background
Malnutrition is associated with adverse prognosis in heart failure patients. However, in patients with heart failure with preserved ejection fraction (HFpEF), the effects of change in nutritional status during hospitalization on prognosis is unknown. Geriatric nutritional risk index (GNRI) is a widely used objective index for evaluating nutritional status. Low GNRI (<92) has moderate or severe nutritional risk and high GNRI (≥92) has no or low nutritional risk.
Purpose
The purpose of this study was to clarify the effect of change in GNRI during hospitalization on one-year mortality and the association between the value of GNRI and one-year mortality in patients with HFpEF.
Methods
We prospectively registered patients with HFpEF in PURSUIT-HFpEF registry when they were hospitalized for heart failure in 29 hospitals. Preserved ejection fraction was defined as more than 50% of left ventricular ejection fraction. Of the 486 patients who registered PURSUIT-HFpEF, 228 cases with one-year follow-up data were examined. GNRI was calculated as follows: 14.89 × serum albumin (g/dl) + 41.7 × body mass index/22.
Results
Mean age was 81±10 years and 100 patients (44%) were male. During a median [interquartile range] follow-up period of 374 [342, 400] days, 28 patients (12%) died. Mortality was significantly higher in patients with low GNRI at admission (n=65) than those with high GNRI at admission (n=163) (26% vs. 9%, log-rank P=0.011) and higher in patients with low GNRI at discharge (n=109) than those with high GNRI at discharge (n=119) (22% vs. 6%, log-rank P=0.002). Multivariate analysis with Cox proportional hazard model with patient characteristics at admission revealed that low GNRI at admission was independently associated with mortality (hazard ratio: 0.96, 95% CI: 0.93–0.99, P=0.035) and that with patient characteristics at discharge revealed that low GNRI at discharge was independently associated with mortality (hazard ratio: 0.94, 95% CI: 0.91–0.97, P<0.001). We also compared mortality by dividing patients into 4 group according to whether GNRI was high or low at the time of admission and discharge. Patients with low GNRI at admission and at discharge (n=59) exhibited the highest mortality, on the other hand, patients with high GNRI at admission and low GNRI at discharge (n=50) exhibited higher mortality than those with high GNRI both at admission and at discharge (n=113) (Low and low: 28% vs. High and low: 14% vs. High and high: 6% vs. Low and high: 0%, log-rank P=0.010).
All cause mortality
Conclusion
GNRI at admission or at discharge was independently associated with one-year mortality in patients with HFpEF. Moreover, worsening GNRI during hospitalization is associated with the worse prognosis. It is important to prevent lowering GNRI during treatment of acute decompensated HFpEF.

Abstract
Research suggests that oxygen desaturation and sleep stage during obstructive sleep apnea (OSA) are related to the magnitude of high blood pressure (BP) in a laboratory setting. However, in a clinical setting, these associations have not been well studied. We used a noninvasive oscillometric BP measurement device to investigate the association between oxygen-triggered BP levels at the end of each OSA episode and the characteristics of the preceding OSA episode. In 42 newly diagnosed OSA patients (average age, 63.5±12.5 years; average apnea-hypopnea index, 32.6±18.2 per hour), 258 BP measurements were obtained at the end of OSA episodes. Hypoxia-peak systolic BP (SBP), defined as the maximum oxygen-triggered SBP value, was significantly higher in rapid eye movement sleep (144.9±19.9 mm Hg) than in non-rapid eye movement stage 1 sleep (129.5±15.1 mm Hg; P<0.001) and non-rapid eye movement stage 2 sleep (129.4±14.7 mm Hg; P<0.001). In a multivariate-linear mixed model, the lowest oxygen saturation percentage during each OSA episode was associated with increased hypoxia-peak SBP (-0.501 mm Hg; P<0.001), nocturnal SBP surge (-0.395 mm Hg; P<0.001), defined as the difference between the hypoxia-peak SBP and the mean nocturnal SBP, and maximum value of SBP surge (-0.468 mm Hg; P<0.001), defined as the difference between the hypoxia-peak SBP and the minimum nocturnal SBP independent of sleep stage. These values were not associated with the duration of each OSA episode. The contribution of rapid eye movement sleep and severe oxygen desaturation to OSA-related BP elevation measured with a noninvasive oscillometric method was determined in a clinical setting.

Abstract
Constipation is associated with cardiovascular events. Changes to the intestinal microbiota by constipation can induce atherosclerosis, blood pressure rise, and cardiovascular events. Constipation increases with age and often coexists with cardiovascular risk factors. In addition, strain at stool causes blood pressure rise, which can trigger cardiovascular events such as congestive heart failure, arrhythmia, acute coronary disease, and aortic dissection. However, because cardiovascular medical research often focuses on more dramatic interventions, the risk from constipation can be overlooked. Physicians caring for patients with cardiovascular disease should acknowledge constipation and straining with it as important cardiovascular risk, and prematurely intervene to prevent it. The authors review and discuss the relationship between constipation and cardiovascular disease.

Abstract
BACKGROUND Brain natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are prognostic biomarkers. Although these 2 peptides differ with regard to biological characteristics, there are few reports on the differences between BNP and NT-proBNP with regard to cardiovascular events or according to sex.Methods and Results:Between 2005 and 2012, this study analyzed 3,610 of 4,310 Japanese outpatients (mean age, 65 years; men, n=1,664; women, n=1,947) with a history of at least one cardiovascular event who were recruited to the Japan Morning Surge-Home Blood Pressure Study. During an average 4-year follow-up, there were 129 cardiovascular events. Both median BNP (21.1 pg/mL; IQR, 10.9-40.6 pg/mL vs. 16.2 pg/mL, IQR, 7.2-36.2 pg/mL, P<0.001) and median NT-proBNP (54.7 pg/mL; IQR, 30.2-102.6 pg/mL vs. 44.9 pg/mL, IQR, 20.7-92.6 pg/mL, P<0.001) were significantly higher in women than in men. A 1-SD increment in log-transformed BNP (hazard ratio [HR], 2.18; 95% CI: 1.53-3.10) and NT-proBNP (HR, 2.39; 95% CI: 1.73-3.31) was associated with a significant increase in cardiovascular events in women; in men, only NT-proBNP showed this association. There was an interaction between log-transformed BNP (P=0.007) or NT-proBNP (P=0.001) and cardiovascular events according to sex. CONCLUSIONS Both BNP and NT-proBNP predicted cardiovascular outcomes in a large Japanese clinical population. BNP and NT-proBNP were significantly stronger predictors in women than in men.

Abstract
Electric field effects on magnetism in metals have attracted widespread attention, but the microscopic mechanism is still controversial. We experimentally show the relevancy between the electric field effect on magnetism and on the electronic structure in Pt in a ferromagnetic state using element-specific measurements: x-ray magnetic circular dichroism (XMCD) and x-ray absorption spectroscopy (XAS). Electric fields are applied to the surface of ultrathin metallic Pt, in which a magnetic moment is induced by the ferromagnetic proximity effect resulting from a Co underlayer. XMCD and XAS measurements performed under the application of electric fields reveal that both the spin and orbital magnetic moments of Pt atoms are electrically modulated, which can be explained not only by the electric-field-induced shift of the Fermi level but also by the change in the orbital hybridizations.

Abstract
A new liquid-liquid blood gas exchange system was investigated using a veno-venous low flow extracorporeal circuit. A 2 m2 hollow fiber dialyzer served as the interface of the blood and oxygen carrier (a 38 percent FC-43, perfluorocarbon emulsion in a buffered electrolyte solution), which was continuously recycled through a bubble oxygenator. Experiments were performed on five mongrel dogs under general anesthesia. Upon the arrest of spontaneous ventilation, the dogs' lungs were inflated with 50% oxygen gas under a positive pressure of 10 cmH2O. After 10 min of apnea the dogs' PaO2 decreased to 37 ± 14 mmHg, and the extracorporeal circulation was started at 10 ml/min/kg b./w. At 15 min the PaO2 had risen to 80 ± 41 mmHg and at 30 min to 121 ± 17 mmHg. The oxygen transfer was 8.3 ± 2.3 ml/min. The extracorporeal circulation was continued 5h, when PaO2 reached 156 ± 90 mmHg, and PaCO2 148 ± 43 mmHg, then stopped. Fifteen minutes later, the PaO2 had returned to 32 ± 10 mmHg. These findings indicate that our blood gas exchange system can supply a sufficient amount of oxygen to the body under apnea with continuous positive airway pressure.

Abstract
Objectives The objective of this study was to investigate the therapeutic effect of peripheral blood mononuclear cells (PBMNCs) treated with quality and quantity control culture (QQ-culture) to expand and fortify angiogenic cells on the acceleration of fracture healing. Methods Human PBMNCs were cultured for seven days with the QQ-culture method using a serum-free medium containing five specific cytokines and growth factors. The QQ-cultured PBMNCs (QQMNCs) obtained were counted and characterised by flow cytometry and real-time polymerase chain reaction (RT-PCR). Angiogenic and osteo-inductive potentials were evaluated using tube formation assays and co-culture with mesenchymal stem cells with osteo-inductive medium in vitro. In order to evaluate the therapeutic potential of QQMNCs, cells were transplanted into an immunodeficient rat femur nonunion model. The rats were randomised into three groups: control; PBMNCs; and QQMNCs. The fracture healing was evaluated radiographically and histologically. Results The total number of PBMNCs was decreased after QQ-culture, however, the number of CD34+ and CD206+ cells were found to have increased as assessed by flow cytometry analysis. In addition, gene expression of angiogenic factors was upregulated in QQMNCs. In the animal model, the rate of bone union was higher in the QQMNC group than in the other groups. Radiographic scores and bone volume were significantly associated with the enhancement of angiogenesis in the QQMNC group. Conclusion We have demonstrated that QQMNCs have superior potential to accelerate fracture healing compared with PBMNCs. The QQMNCs could be a promising option for fracture nonunion.

Abstract
In the present study, a continuous radioactive aerosol measurement system (CRAMS) was developed for measurements of radioactive plume (e.g. 131I, 134Cs and 137Cs) under the emergency situation, and measurements of radon/thoron progeny under the existing situation. As a result, it is suggested that the CRAMS could follow the variation of radon concentration, and the detection limit of the CRAMS under ambient dose equivalent rate of 20µSvh-1, where the temporary evacuation is required within one week in the Japanese regulation, was evaluated to be 129Bqm-3 in the manner of ISO11929.

Abstract
An intermolecular energy transfer system is developed for studying the stability of nanoaggregate(s) (NAs) in complex solution and cell culture by one- and two-photon fluorescence microscopy and optical imaging. The system allows facile addition of one or more tumor targeting molecules, one of which is exemplified here. NAs functionalized with an MRI and optical probe, with and without folic acid, remain stable in fetal bovine serum for at least 4 hours. HeLa cell cultures showed a clear difference between NAs non-targeted and targeted to folate receptors, with both NAs appearing to be taken up by the cells through different mechanisms. An MRI relaxivity, r1, of 9 mM-1 s-1 at 310 K and 1.4 T was measured associated with the increased rotational correlation time of the NAs. These NAs may have application in the targeted drug delivery of hydrophobic drugs such as doxorubicin (DOX).

Abstract
The aim of this study was to compare an aliskiren/amlodipine combination with high-dose amlodipine monotherapy on ambulatory blood pressure monitoring (ABPM) and organ protection. The study was a prospective, randomized, multicenter, open-label trial in elderly essential hypertensive patients. A total of 105 patients with clinic BP (CBP) ≥140/90 mm Hg with amlodipine 5 mg were randomly allocated to aliskiren (150-300 mg)/amlodipine (5 mg) (ALI/AML group, n=53) or high-dose amlodipine (10 mg) (h-dAML group, n=52) and treated for 16 weeks. Each patient's CBP, ABPM, urine albumin-to-creatinine ratio (UACR), and brachial-ankle pulse wave velocity (baPWV) were measured at baseline and at the end of the study. The ALI/AML and h-dAML groups showed similarly reduced mean 24-hour SBP, daytime SBP, nighttime SBP, and baPWV. However, UACR reduction was significantly greater in the ALI/AML group (P=.02). ALI/AML was significantly less effective in reducing early-morning BP (P=.002) and morning BP surge (P=.001) compared with h-dAML.
