Abstract
Scope of the study was to find more effective N fertilisation doses and applications to reach not only higher quantity but better quality grains as well as to be able to help preserving the continuity of feed and food quality improvement, since wheat is one of the most consumed crops all over the world.Samples of winter wheat (Triticum aestivum L.) varieties harvested from the experimental field of the Szent István University in two consecutive crop seasons had been examined in the laboratory of the Crop Production Institute. Effects of nitrogen (N) application on the performance of grain protein were tested. Five high quality winter wheat varieties were studied regarding grain quality traits affected by applying undivided and split doses of N. The evaluated samples show that increasing doses of N topdressing and increasing time of application have beneficial effects on the yield and the value of protein content. Wheat grain protein value ranged between 9.9% of the untreated Mv Karéj and Alföld, where the 120+40 kg ha-1 N was applied resulting in the highest value of 16.0%. Similarly, the gluten values among untreated and N applied plots were in a wide range. Mv Karéj had the lowest wheat gluten value on untreated plot with 18.4% and Alfold had the highest value with 36.8% on the plot where the 120+40 kg ha-1 N was applied. There were no significant changes recorded on test weight and thousand kernel weight. In the case of baking quality, there were significant differences between varieties. The best records were obtained in the case of Mv Toborzö followed by Mv Karéj.

Abstract
BACKGROUND Methimazole embryopathy is caused by maternal methimazole intake during early pregnancy. It causes fetal malformations such as choanal atresia, esophageal atresia, aplasia cutis, omphalomesenteric duct remnants, urachal remnants, and omphalocele. Gallbladder agenesis is sometimes complicated with other malformations, but there have been no reports of gallbladder agenesis due to methimazole or concomitant methimazole embryopathy with gallbladder agenesis. CASE REPORT The mother of a male neonate had taken methimazole for hyperthyroidism until pregnancy was recognized at 7 weeks of gestation. Ultrasonography at 12 weeks and 4 days of gestation showed the fetus had a cystic lesion in the umbilical region. The child was born at the gestational age of 38 weeks and 5 days. At birth there was omphalocele, omphalomesenteric fistula, and a scalp defect, and the child was diagnosed with methimazole embryopathy. Ultrasonography could not identify the gallbladder. Emergency surgery was performed for omphalocele with omphalomesenteric fistula on day 0. The intestine, including the omphalomesenteric fistula, was resected. Postoperative blood testing revealed hypothyroidism, so the patient was administered levothyroxine. Although MRI did not detect the gallbladder, it showed dilatation of the biliary duct. Hypothyroidism was well controlled by levothyroxine, so the patient was discharged with outpatient follow-up for the gallbladder agenesis. Six months later, the patient is asymptomatic. CONCLUSIONS Concomitant gallbladder agenesis with methimazole embryopathy has not been previously reported. In the case of a dilated common bile duct, even when asymptomatic in the neonatal period, gallbladder agenesis demands long-term follow-up because of possible manifestation of choledocholithiasis or biliary malignant tumors.

Abstract
Despite their prevalence and burdens, oral diseases are neglected in universal health coverage. In Japan, a 30% copayment (out of pocket) by the user and a 70% contribution by Japan’s universal health insurance (JUHI) are required for dental and medical services. From the age of 70 y, an additional 10% is offered by JUHI (copayment, 20%; JUHI, 80%). This study aimed to investigate the effect of cost on dental service use among older adults under the current JUHI system. A regression discontinuity quasi-experimental method was used to investigate the causal effect of the JUHI discount policy on dental visits based on cross-sectional data. Data were derived from the 2016 Japan Gerontological Evaluation Study. This analysis contained 7,161 participants who used JUHI, were aged 68 to 73 y, and responded to questions regarding past dental visits. Analyses were controlled for age, sex, number of teeth, and equalized household income. Mean ± SD age was 72.1 ± 0.79 y for the discount-eligible group and 68.9 ± 0.78 y for the noneligible group. During the past 12 mo, significantly more discount-eligible participants had visited dental services than noneligible participants (66.0% vs. 62.1% for treatment visits, 57.7% vs. 53.1% for checkups). After controlling for covariates, the effect of discount eligibility was significant on dental treatment visits (odds ratio [OR], 1.36; 95% CI, 1.32 to 1.40) and dental checkups (OR, 1.49; 95% CI, 1.44 to 1.54) in the regression discontinuity analysis. Similar findings were observed in triangular kernel-weighted models (OR, 1.38 [95% CI, 1.34 to 1.44]; OR, 1.52 [95% CI, 1.47 to 1.56], respectively). JUHI copayment discount policy increases oral health service utilization among older Japanese. The price elasticity for dental checkup visits appears to be higher than for dental treatment visits. Hence, reforming the universal health coverage system to improve the affordability of relatively inexpensive preventive care could increase dental service utilization in Japan.

Abstract
Background Abuse can be a cause of pediatric duodenal injury. Patients who have been injured by abuse tend to have delay before medical examination, they may therefore have especially poor prognosis. Case presentation A 3‐year‐old boy presented with abdominal pain and was diagnosed with duodenal perforation. He was urgently transferred to our hospital for surgery. There was no clear history of trauma according to initial parent interviews, but old bruises were observed in several places. Paternal remarks about the injury mechanism were contradictory to bruit findings. Eventually, the mother reported daily paternal domestic violence against the patient. Duodenal perforation was considered to be caused by physical abuse, and emergent surgery was carried out. Intraoperative findings revealed transection at the horizontal part of the duodenum. Primary repair was difficult due to severe damage, so duodenojejunostomy was undertaken. Conclusion Duodenojejunostomy was successfully carried out as emergent surgery for severely damaged duodenal transection.

Abstract
Background:Patients with lupus nephritis (LN) and rheumatoid arthritis (RA) are at risk of serious infections (SIs) due to the impact of the disease itself and treatments that modulate immune system. Though the epidemiology of RA has been well-established by developing many targeted DMARDs (tDMARDs) including biologics and targeted synthesized DMARDs, LN is a very rare disease. Therefore, a large sample size with a significant number of cases is required to determine the exact risk of SIs in LN.Objectives:To compare the incidence rates of SIs resulting in an inpatient claim in adult patients with LN compared with RA with or without tDMARDs using hospital claims data in Japan.Methods:LN and RA were identified using claims data provided by Medical Data Vision Co., Ltd (Tokyo, Japan) between April 2008 and June 2019 which was extracted 5thSeptember 2019. Data between January 2010 and December 2018 was used for analysis. Patients with LN and RA were identified using modifications to algorithms developed before [1, 2]. LN patients were required to have continuous insurance claim for both systemic lupus erythematosus (SLE) and LN for ≥ 6 months after index date and then RA patients had continuous insurance claim for RA for ≥ 6 months after index date. First incident SIs were defined as those that resulted in an inpatient claim for a pre-specified set of ICD-10 code. Incidence rates (IRs) were calculated along with 95% confidence intervals (CI).Results:The LN, RA, RA treated with tDMARDs and RA treated without tDMARDs cohorts included 6,403, 108,317, 16,450, and 91,867 patients, respectively. As anticipated, the LN and RA cohorts were predominantly female and the RA cohort was generally older than the LN cohorts. IRs per 1,000 person-year(PY) [95% CI] for pneumocystis carini pneumonia were 28.2 [26.0-30.4] in LN, 8.5 [8.2-8.8] in RA, 12.6 [11.7-13.5] in RA with tDMARDs and 7.7 [7.4-8.0] in RA without tDMARDs. IRs per 1,000 PY for septicaemia infection were 23.3 [21.3-25.3] in LN, 12.1 [11.7-12.4] in RA, 13.3 [12.3-14.2] in RA with tDMARDs and 11.8 [11.5-12.2] in RA without tDMARDs. IRs per 1,000 PY for cytomegalovirus infection were 13.4 [11.9-14.9] in LN, 4.4 [4.2-4.6] in RA, 6.2 [5.6-6.8] in RA with tDMARDs and 4.1 [3.8-4.3] in RA without tDMARDs. IRs per 1,000 PY for tuberculosis were 7.2 [6.0-8.3] in LN, 6.7 [6.5-7.0] in RA, 18.2 [17.1-19.3] in RA with tDMARDs and 4.4 [4.2-4.7] in RA without tDMARDs.Conclusion:In this population-based analysis of claims data from Japan, the IRs of SI such as pneumocystis carini pneumonia, septicemia infection and cytomegalovirus infection were higher in LN than in RA. And also, the incidence of tuberculosis in RA treated with tDMARDs was highest among these cohorts. These findings demonstrate the relative contribution of age, immunosuppressive therapies and disease-related factors in LN and RA.References:[1]Pawar A, et al. Ann Rheum Dis. 2019 Apr;78(4):456-464.

Abstract
Auxin controls numerous growth processes in land plants through a gene expression system that modulates ARF transcription factor activity1-3. Gene duplications in families encoding auxin response components have generated tremendous complexity in most land plants, and neofunctionalization enabled various unique response outputs during development1,3,4. However, it is unclear what fundamental biochemical principles underlie this complex response system. By studying the minimal system in Marchantia polymorpha, we derive an intuitive and simple model where a single auxin-dependent A-ARF activates gene expression. It is antagonized by an auxin-independent B-ARF that represses common target genes. The expression patterns of both ARF proteins define developmental zones where auxin response is permitted, quantitatively tuned or prevented. This fundamental design probably represents the ancestral system and formed the basis for inflated, complex systems.

Abstract
IMPORTANCE Childhood maltreatment can have significant consequences on health through the life course, but its association with health care costs in later life is not widely known. OBJECTIVE To assess whether a history of childhood maltreatment is associated with additional medical costs among older adults in Japan. DESIGN, SETTING, AND PARTICIPANTS This population-based cross-sectional study used data from the Japan Gerontological Evaluation Study, 2013, linked with national health insurance claims data from April 2012 to March 2014 for 1 municipality that participated in the Japan Gerontological Evaluation Study, 2013. The municipality had more than 1.5 million residents, and 978 independent individuals aged 65 to 75 years were included in the analysis. Data were analyzed from October 2017 to February 2019. EXPOSURES Childhood maltreatment, including physical abuse, emotional neglect, emotional abuse, and witnessing intimate partner violence. MAIN OUTCOMES AND MEASURES Mean annual medical costs between April 2012 and March 2013 and between April 2013 and March 2014. RESULTS Among 978 independent older adults (mean [SD] age, 70.6 [2.9] years; 426 [43.6%] men), 44 (4.5%) witnessed intimate partner violence, 19 (1.9%) were physically abused, 104 (10.6%) were emotionally neglected, and 56 (5.7%) were emotionally abused in childhood. In total, 176 older adults (18.0%) experienced at least 1 type of childhood maltreatment. Mean annual medical costs of those who experienced any childhood maltreatment were significantly higher than of those who did not (difference, ¥136 456 [US$1255]; 95% CI, ¥38 155-¥234 757 [US$351-US$2160]; P = .007). Those who experienced emotional neglect incurred more mean medical costs than those who did not (difference, ¥161 400 [US$1484]; 95% CI, ¥42 779-¥280 021 [US$394-US$2576]; P = .008). The association of any childhood maltreatment with medical costs remained significant after controlling for age and sex (average marginal effect, ¥116 098 [US$1068]; SE, ¥53 620 [US$493]; 95% CI, ¥11 004-¥221 192 [US$101-US$2034]; P = .03). The estimated additional costs associated with childhood maltreatment would be more than ¥333 billion (US$3.1 million) per year nationwide. CONCLUSIONS AND RELEVANCE In this study, childhood maltreatment was associated with additional medical costs among older adults living in Japan. This finding underlines the importance of primary and secondary prevention of child maltreatment.

Abstract
Abstract
Novel analytical methods based on real-time quantitative polymerase chain reactions by use of new reference molecules were validated in interlaboratory studies for the quantitation of genetically modified (GM) maize and soy. More than 13 laboratories from Japan, Korea, and the United States participated in the studies. The interlaboratory studies included 2 separate stages: (1) measurement tests of coefficient values, the ratio of recombinant DNA (r-DNA) sequence, and endogenous DNA sequence in the seeds of GM maize and GM soy; and (2) blind tests with 6 pairs of maize and soy samples, including different levels of GM maize or GM soy. Test results showed that the methods are applicable to the specific quantitation of the 5 lines of GM maize and one line of GM soy. After statistical treatment to remove outliers, the repeatability and reproducibility of these methods at a level of 5.0% were <13.7 and 15.9%, respectively. The quantitation limits of the methods were 0.50% for Bt11, T25, and MON810, and 0.10% for GA21, Event176, and Roundup Ready soy. The results of blind tests showed that the numerical information obtained from these methods will contribute to practical analyses for labeling systems of GM crops.

Abstract
A variety of plants in diverse taxa can reproduce asexually via vegetative propagation, in which clonal propagules with a new meristem(s) are generated directly from vegetative organs. A basal land plant, Marchantia polymorpha, develops clonal propagules, gemmae, on the gametophyte thallus from the basal epidermis of a specialized receptacle, the gemma cup. Here we report an R2R3-MYB transcription factor, designated GEMMA CUP-ASSOCIATED MYB1 (GCAM1), which is an essential regulator of gemma cup development in M. polymorpha. Targeted disruption of GCAM1 conferred a complete loss of gemma cup formation and gemma generation. Ectopic overexpression of GCAM1 resulted in formation of cell clumps, suggesting a function of GCAM1 in suppression of cell differentiation. Although gemma cups are a characteristic gametophyte organ for vegetative reproduction in a taxonomically restricted group of liverwort species, phylogenetic and interspecific complementation analyses support the orthologous relationship of GCAM1 to regulatory factors of axillary meristem formation, e.g., Arabidopsis REGULATOR OF AXILLARY MERISTEMS and tomato Blind, in angiosperm sporophytes. The present findings in M. polymorpha suggest an ancient acquisition of a transcriptional regulator for production of asexual propagules in the gametophyte and the use of the regulatory factor for diverse developmental programs, including axillary meristem formation, during land plant evolution.

Childhood maltreatment can have a significant impact on health across the life course, but its impact on health care costs in later life is unknown in Japan. This study aims to assess additional medical costs of Japanese older people with childhood maltreatment history.
Methods
Data from the Japan Gerontological Evaluation Study (JAGES) 2013, a population-based cohort of independent people aged 65 years or older across Japan were used and linked uniquely with the database of health insurance claims for residents of a city with more than 1.5 million citizens, aged 75 years or younger (N = 978). Average annual medical costs for April 2012 and March 2013 and April 2013 and March 2014 were calculated and compared between those who experienced childhood maltreatment and those who did not, using generalized linear models.
Results
4.5% of our sample witnessed their father physically abusing their mother, 1.9% were physically abused, 10.6% were emotionally neglected, and 5.7% were emotionally abused in their childhood. Average medical costs of those with any childhood maltreatment (N = 176, 18.0% of the sample) were significantly higher than those without maltreatment (549,468JPY vs. 413,013JPY (1USD is equivalent to 110JPY); p = 0.007). When examining the effect of each type of maltreatment, average costs of those with emotional neglect were higher than the counterpart (573,481JPY vs. 412,082JPY; p = 0.008). Average costs of those who experienced physical abuse were also higher than those who did not (726,254JPY vs 431,106JPY; p = 0.035). The effect of any childhood maltreatment remained statistically significant after older adults’ age and gender were controlled (p = 0.03).
Conclusions
Our findings suggest that childhood maltreatment is strongly associated with additional medical costs among older Japanese. If it was truly causal, it can be estimated that additional medical costs associated with childhood maltreatment can be more than 333 billion JPY per year nationwide.
Key messages
Average annual medical costs of older adults with any childhood maltreatment history were significantly 116,098 JPY greater than those with no maltreatment history. As for each type of childhood maltreatment, emotional neglect tends to increase medical costs in late adulthood.

Abstract
BACKGROUND The difference in prevalence of fatigue among postgraduate trainees between the United States and Japan is unknown. METHODS A cross-sectional survey using Iowa Fatigue Scale was administered on postgraduate trainees in two internal medicine residency programs in New York and five postgraduate residency programs in Japan. RESULTS Of the 393 trainees, 135 (34%) completed the survey. Seventy-seven (57%) were US trainees. Both fatigue (42% vs 81%) and severe fatigue (4% vs 19%) were more prevalent in Japan (P < .01). US trainees felt more productive during work hours but less fatigued. CONCLUSIONS Fatigue was more prevalent among postgraduate trainees in Japan.

Abstract
Small bowel perforation by an ingested foreign body (FB) is a rare abdominal emergency. Computed tomography scan is most effective but imperfect for diagnosis. Inquiring about FB ingestion and a high index of suspicion are very important. Laparoscopic surgery is effective even in this rare abdominal emergency. Extracorporeal handling of the affected small bowel is useful in this condition.
Introduction Presently, the advantage of laparoscopic surgery is widely recognized and it is gaining popularity not only in elective abdominal surgeries but also in various kinds of emergent abdominal surgeries. This report describes two patients diagnosed with ileal perforation due to an ingested foreign body (FB)—a rare abdominal emergency—who were treated laparoscopically. Presentation of case Both patients were brought in by an ambulance to our hospital, with complaints of increasing lower abdominal pain. Computed tomography scan revealed a small bowel perforation due to an ingested FB in both patients, and laparoscopy-assisted partial ileal resection was immediately performed. Their postoperative recoveries were uneventful. Discussion Both patients with this rare abdominal emergency were successfully treated with laparoscopic surgery. Its feasible diagnostic and therapeutic abilities and decreased invasiveness contributed to their uneventful and fast recoveries. Extracorporeal handling of the affected small bowel via mini-laparotomy was useful in this setting as it was safe, fast, and cost-effective. Conclusion Laparoscopic surgery is effective, even for this rare abdominal emergency. Moreover, laparoscopy-assisted surgery accompanying mini-laparotomy is a rational treatment approach, especially for this condition.

Abstract
Abstract
Background
Myofibroblasts, which are activated fibroblasts, play an important role in interstitial fibrosis in non-ischemic dilated cardiomyopathy (NIDCM). Recently, human epididymal body protein 4 (HE4) has attracted attention as a marker specific to myofibroblasts. However, the prognostic impact of HE-4 on cardiovascular events in NIDCM patients has not been reported.
Purposes
The purpose of this study was to investigate the impact of circulating serum HE4 on the prognosis in patients with NIDCM.
Methods
Forty-four NIDCM patients underwent echocardiography, laboratory measurements, cardiac catheterization, and endomyocardial biopsy within one week under stable heart failure condition. Patients with cancer were excluded from this study. We collected blood samples from peripheral vain, ascending aorta, and coronary sinus during cardiac catheterization and measured serum HE4 level. They were divided into two groups at the median of HE4 level: High-HE4 group (HE4 >69 pmol/L); n=22, Low-HE4 group (HE4 <69 pmol/L); n=22. Cardiac composite event was defined as cardiac related deaths and hospitalization due to worsening heart failure.
Results
The mean age, left ventricular ejection fraction (LVEF), and plasma brain natriuretic peptide level were 56 years, 32%, and 205 pg/mL. Between two groups, there were no significant differences in age, gender, LVEF, left ventricular end-diastolic diameter, cardiac index, and pulmonary capillary wedge pressure. However, estimated glomerular filtration rate was significantly lower in the High-HE4 group (p=0.025). Kaplan-Meier survival analysis revealed that the High-HE group had a higher rate of cardiac composite event (p=0.011, see Figure). However, as for the pathological analysis, not only the peripheral HE4 level but also HE4 value subtracting coronary sinus from ascending aorta did not significantly correlate with collagen volume fraction in biopsy samples.
Circulating HE4 level and prognosis
Conclusion
Elevated circulating HE4 is associcated with poor prognosis in ambulatory patients with NIDCM.

Abstract
Abstract
Background
The spleen has been recognized as an important organ to reserve 20–30% of the total blood volume. Generally, splenomegaly has been thought to be related to congestion. However, in the setting of hypovolemic shock or hypoxemia, it has been reported that spleen contracted and splenic volume decreased. On the other hand, in advanced heart failure (HF), the hemodynamics is characterized by both low cardiac output (LO) and systemic congestion, and patients sometimes need support of left ventricular assist device (LVAD). However, it remains unclear about the association between spleen size and hemodynamic parameters in patients with LO who need LVAD support.
Purpose
The purpose of this study was to investigate the relationship between spleen size and hemodynamic parameters in advanced HF before and after LVAD implantation.
Methods
We enrolled 12 advanced HF patients with LVAD (11 males, 45±10 years). All patients underwent blood test, echocardiography, right heart catheterization, and computed tomography (CT) before and after LVAD implantation. Spleen size was measured by CT volumetry. We excluded patients with splenic infarction, or any infections, or mean right atrial pressure (RAP) <5mmHg because of a possibility of hypovolemic status. LO was defined as CI less than 2.2L/min/m2.
Results
At pre- and post-LVAD implantation, cardiac output, cardiac index (CI), mean RAP, and mean pulmonary capillary wedge pressure were 3.1±0.6 vs. 4.9±0.9L/min, p=0.002; 1.7±0.3 vs. 2.8±0.3L/min/m2, p=0.002; 14±5 vs. 9±3mmHg, p=0.059; and 30±7 vs. 10±3mmHg, p=0.002, respectively. The serum brain natriuretic peptide level had significantly decreased (1101 [517–1446] vs 74 [35–216] pg/mL, p=0.002). In all patients, CI had increased to over 2.2L/min/m2. The splenic volume significantly increased from pre- to post-LVAD implantation (172±48 vs. 233±78mL, p=0.002) (Figure). Furthermore, all patients were divided into two groups; elevated RAP group (n=4) and non-elevated RAP group (n=8) after LVAD support. In elevated RAP group, there were no significant changes in the spleen size between pre- and post-LVAD implantation (167±45 vs. 223±111mL, p=0.068). On the other hand, in non-elevated RAP group, the spleen volume had significantly increased from pre- to post-LVAD support (172±53 vs. 231±62mL, p=0.011). In addition, there was one patient whose hemodynamic state had changed to LO again because of LVAD failure due to pump thrombosis. In this case, the splenic volume was 212mL before LVAD implantation with LO, and increased to 418mL after LVAD implantation with non-LO, although decreased to 227mL after LVAD pump failure with LO again.
Splenic volume changes
Conclusions
The spleen may change its size in order to keep cardiac output by regulating cardiac preload depending on the systemic perfusion in advanced HF with LVAD.

Abstract
Abstract
Background
In patients with hypertensive acute decompensated heart failure (ADHF), intravenous vasodilators are commonly used. However, little is known about optimal use in blood pressure (BP) management to avoid acute kidney injury (AKI).
Purpose
To investigate the association between systolic BP (SBP) changes in first 6 h and incidence of AKI within 48 h in patients with hypertensive ADHF.
Methods
Post-hoc analysis was performed on a prospectively enrolled cohort. We investigated 245 patients with ADHF and SBP >140 mmHg on arrival (mean age, 76 years; 40% female). We defined “SBP-fall” as maximum percent reduction in SBP 6h after intravenous treatment. AKI was defined as serum creatinine (SCr) ≥0.3 mg/dL, or urine output <0.5 mL/kg/h at 48 h.
Results
Mean SBP, SBP-fall and SCr level at arrival were 180 mmHg, 29.4%, and 1.21 mg/dL, respectively. Sixty-six patients experienced AKI. There were no significant differences in age, NYHA functional class, SBP and SCr at admission between AKI and Non-AKI group. AKI group had the greater SBP-fall compared with Non-AKI (36.7%versus 27.2%, p≤0.0001). Logistic regression analyses revealed that SBP-fall had an independent predictor of AKI (Table). In addition, SBP-fall had positive association with the number of concomitant used intravenous vasodilators in first 6 h (Figure).

Abstract
It has been reported that fermented products (FPs) prepared from sweet potato-shochu distillery by-product suppressed weight gain and decreased serum cholesterol levels in mice under normal dietary conditions. Furthermore, from the information gained from the above data regarding health benefits of the FPs, the aim of this study was evaluating the effects of dietary FPs on lipid accumulation and gut microbiota in mice with or without cholesterol-load in the diet. C57BL/6N mice were fed normal (CO) diet, CO with 10% FPs (CO + FPs) diet, cholesterol loaded (HC) diet, or HC with 10% FPs (HC + FPs) diet for 8 weeks. The mice were then euthanized, and blood samples, tissue samples, and feces were collected. The adipose tissue weight and liver triglyceride levels in the HC + FPs diet groups were significantly reduced compared to that in the HC diet groups. However, FPs significantly increased the serum non-high-density lipoprotein cholesterol (HDL-C) levels, the ratio of non-HDL-C to HDL-C and hepatic total cholesterol levels in mice fed cholesterol-loaded diet compared with that of the HC diet group. Since dietary FPs significantly decreased the protein expression levels of cholesterol 7 alpha-hydroxylase 1 in the HC + FPs diet groups, the cholesterol accumulation in FPs group may be explained by insufficient catabolism from cholesterol to bile acid. In addition, the dietary FPs tended to increase Clostridium cluster IV and XIVa, which are butyrate-producing bacteria. Related to the result, n-butyrate was significantly increased in the CO + FPs and the HC + FPs diet groups compared to their respective control groups. These findings suggested that dietary FPs modulated the lipid pool and gut microbiota.

Abstract
Diamond has two crystallographically inequivalent sites in the unit cell. In doped diamond, dopant occupation in the two sites is expected to be equal. Nevertheless, preferential dopant occupation during growth under nonequilibrium conditions is of fundamental importance, for example, to enhance the properties of nitrogen-vacancy (N-V) centers; therefore, this is a promising candidate for a qubit. However, the lack of suitable experimental techniques has made it difficult to study the crystal- and chemical-site-resolved local structures of dopants. Here, we confirm the identity of two chemical sites with asymmetric dopant incorporation in the diamond structure, via the photoelectron holography (PEH) of heavily phosphorus (P)-doped diamond prepared by chemical vapor deposition. One is substitutionally incorporated P with preferential site occupations and the other can be attributed to a PV split vacancy complex with preferential orientation. The present study shows that PEH is a valuable technique to study the local structures around dopants with a resolution of crystallographically inequivalent but energetically equivalent sites/orientations. Such information provides strategies to improve the properties of dopant related-complexes in which alignment is crucial for sensing of magnetic field or quantum spin register using N-V centers in diamond.

Abstract
OBJECTIVES Reducing costs related to functional disabilities and long-term care (LTC) is necessary in ageing societies. We evaluated the differences in the cumulative cost of public LTC insurance (LTCI) services by social participation. DESIGN Prospective observational study. SETTING Our baseline survey was conducted in March 2006 among people aged 65 or older who were not eligible for public LTCI benefits and were selected using a complete enumeration in Tokoname City, Japan. We followed up with their LTC services costs over a period of 11 years. Social participation was assessed by the frequency of participation in clubs for hobbies, sports or volunteering. We adopted a classical linear regression analysis and an inverse probability weighting (IPW), with multiple imputation of missing values. PARTICIPANTS Functionally independent 5377 older adults. PRIMARY OUTCOME MEASURES The cumulative cost of public LTCI services for 11 years. RESULTS Even when adjusting for the confounding variables, social participation at the baseline was negatively associated with the cumulative cost of LTCI services. The IPW model showed that in respondents who participated in hobby activities once a week or more, the cumulative cost of LTCI services for 11 years was lower, approximately US$3500 per person, in comparison to non-participants. Similarly, that in respondents who participated in sports group or clubs was lower, approximately US$6000 than non-participants. CONCLUSIONS Older adults' participation in community organisations may help reduce future LTC costs. Promoting participation opportunities in the community could ensure the financial stability of LTCI services.
