Abstract
To achieve appropriate blood pressure control in the treatment of hypertension in Japan, this study examined the relationship between office blood pressure and actual antihypertensive drug use in general hospitals following the promulgation of the guidelines for hypertension (JSH2019). This study focused on blood pressure levels and drug use in outpatients on antihypertensive treatment from June to July 2020. The subjects were 2,537 patients classified into four groups based on their medical history, patients with: hypertension only; hypertension and cardiovascular disease; hypertension and dyslipidaemia; and hypertension and diabetes mellitus. The results showed a significant difference in systolic blood pressure (SBP) between patients with hypertension only and those with hypertension and cardiovascular disease (138.3±17.9 mmHg vs 135.6±19.9 mmHg, p<0.05). Regarding actual drug use, it was found that diuretics were prescribed more frequently in patients with hypertension and cardiovascular disease than in those with hypertension alone (15.5% vs 37.9%, p<0.05), even though the number of drugs for hypertension did not differ significantly. In addition, the dose of diuretics was greater only in patients with cardiovascular disease. These results show the actual drug use and blood pressure for each comorbidity. Furthermore, they suggest that the results of antihypertensive treatment may differ by changing the combination and dosage of antihypertensive drugs without changing the number of antihypertensive drugs used. The study also shows the problem of using less diuretics depending on the risk the patient has, and solving the problem may lead to achieving further antihypertensive goals.

Abstract
Valence s electrons in alkali- or coinage-metal clusters are conceived to delocalize over the metal frameworks. The electrons occupy so-called superatomic orbitals (SAOs, i.e., 1S, 1P, 1D, 2S, 1F, ...), which provide an essential picture for understanding the size-dependent, unique properties of these metal clusters. While such electronic shells are unambiguously identified in their photoelectron spectra and supported by electronic structure calculations, characterization of SAOs in heteroatom-doped metal clusters has remained elusive as the doping significantly affects its energy levels and even alters the ordering of SAOs. Here, we present a photoelectron imaging study to explore SAOs formed in Sc-doped and undoped silver cluster anions, AgNSc- (N = 15, 16) and AgN- (N = 18, 19). Photoelectron angular distributions from their outermost SAOs are clearly visualized, whose characters are analyzed with the aid of density functional theory calculations. The present methodology enables us to explore not only the quantized energy levels but also the spatial distributions of SAOs formed in various metal cluster anions.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
OBJECTIVES Most research on the association between parental or family socio-economic status and psychological adjustment in children has been performed mainly in Western countries, while there is limited evidence of such research in Asian countries. We examined the association of parental occupation and educational levels and household income with children's psychological adjustment in Japan. STUDY DESIGN This was a cross-sectional study. METHODS Study subjects were 6329 children aged 3 years. Children's psychological adjustment was assessed using the Strengths and Difficulties Questionnaire. RESULTS Compared with having an unemployed father, having a father who worked in an administrative and managerial or clerical job was associated with a lower prevalence of peer problems. Compared with having an unemployed mother, having a mother who worked in the professional and engineering, sales, service, or manufacturing process area was associated with a lower prevalence of low prosocial behaviors, whereas having a mother who worked in the clerical, service, or manufacturing process area was associated with an increased prevalence of emotional problems. Having a mother who worked in a clerical area was associated with a higher prevalence of conduct problems. Higher paternal and maternal educational levels were inversely associated with the prevalence of conduct problems and hyperactivity but were positively associated with low prosocial behaviors. A higher household income was inversely associated with the prevalence of emotional problems, conduct problems, and hyperactivity. CONCLUSION Parental occupation, educational levels, and household income may affect children's psychological adjustment in Japan.

Evaluating the impact of de-escalating antimicrobial therapy in burn patients: a retrospective cohort study. DIE PHARMAZIE 2022; 77:311-315.

Abstract
Antimicrobials should be used appropriately to minimise the risk of resistant strains arising in association with overuse. De-escalation of antimicrobial therapy is one strategy used to ensure appropriate use, but its safety and efficacy in burn patients are unclear. The aim of this study was to evaluate the safety and efficacy of de-escalation therapy for treating infections in burn patients. This retrospective cohort study investigated patients admitted to our intensive care unit with burns and treated for infection between October 1, 2013, and September 30, 2020. Patients were classified into a de-escalation group (Group D) comprising patients treated with empiric antimicrobial therapy followed by de-escalation and a non-de-escalation group (Group ND) comprising patients who did not undergo de-escalation. Characteristics and outcomes were compared between groups. Forty-three patients met the inclusion criteria, including 15 patients in Group D and 28 patients in Group ND. Bacterial species commonly detected in these patients were Corynebacterium spp. (17.3%), Pseudomonas aeruginosa (16.1%), and Staphylococcus aureus (9.6%) . No inter-group difference was seen in 28-day mortality (6.7% vs 21.4%, p =0.391). Multidrug-resistant strains were detected significantly less frequently in Group D (13.0%) than in Group ND (26.1%, p =0.003). De-escalation was associated with use of two or more antimicrobials as empiric antimicrobial therapy. As the use of de-escalation in infection treatment did not impact 28-day mortality, de-escalation might be safe for treating infections in burn patients.

Abstract
Aims and Background This study evaluated the effect of C-factor on the bond strength of a resin composite to floor and wall dentin using various adhesive systems. Materials and Methods Four dentin substrates (flat wall, flat floor, cavity wall, or cavity floor) were prepared on human molars. Each specimen was restored with one of three adhesives; Clearfil SE Bond, Single Bond, or Clearfil tri-S Bond followed by buildup or filling using Z100 resin composite. The specimen was cut perpendicular to the bonded surface parallel to the floor or wall to obtain beams after light curing at 24,000 mJ/cm2. The microtensile bond strength to wall specimens or the cavity floor was determined. Data were analyzed. Results All adhesive systems exhibited the highest bond strength to flat wall group (p < 0.05). The bond strength to the cavity group was significantly lower than that to the respective flat group regardless of the bonding system (p < 0.05). There was no significant difference in bond strength with Clearfil SE Bond and Clearfil tri-S Bond between the cavity wall and cavity floor (p > 0.05). Conclusion The findings suggested that the strength of bonding to the cavity floor and cavity wall was affected by C-factor regardless of the adhesive system. Bonding to flat wall was higher than flat floor regardless of the adhesive system. Self-etching system provided uniform bond to the cavity wall and cavity floor dentin. However, total etching system reduced bond to the cavity floor than to the cavity wall.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

Abstract
The Hayabusa2 spacecraft investigated the small asteroid Ryugu, which has a rubble-pile structure. We describe an impact experiment on Ryugu using Hayabusa2's Small Carry-on Impactor. The impact produced an artificial crater with a diameter >10 meters, which has a semicircular shape, an elevated rim, and a central pit. Images of the impact and resulting ejecta were recorded by the Deployable CAMera 3 for >8 minutes, showing the growth of an ejecta curtain (the outer edge of the ejecta) and deposition of ejecta onto the surface. The ejecta curtain was asymmetric and heterogeneous and it never fully detached from the surface. The crater formed in the gravity-dominated regime; in other words, crater growth was limited by gravity not surface strength. We discuss implications for Ryugu's surface age.

Abstract
BACKGROUND The present cross-sectional study investigated the associations between low birthweight (LBW), high birthweight, preterm birth (PTB), postterm birth, small for gestational age (SGA), and large for gestational age (LGA) and the prevalence of wheeze and asthma in Japanese children aged three years (age range, 33-54 months; mean age, 38.7 months). METHODS Study subjects were 6364 children. A questionnaire was used to collect all data. Wheeze and asthma were defined according to the criteria of the International Study of Asthma and Allergies in Childhood. RESULTS The prevalence values of wheeze and asthma were 19.5% and 7.7%, respectively. Of the 6364 subjects, 8.8% were classified as LBW (<2500g), 90.4% as normal birthweight, 0.8% as high birthweight (≥4000g), 4.8% as PTB (<37 weeks), 94.8% as term birth, 0.4% as postterm birth (≥42 weeks), 7.8% as SGA (<10th percentile), 82.5% as appropriate for gestational age, and 9.7% as LGA (>90th percentile). Compared with term birth, PTB was independently positively associated with wheeze and asthma: the adjusted ORs (95% CI) were 1.47 (1.11-1.92) and 1.52 (1.02-2.20), respectively. An independent positive association was shown between PTB and wheeze only in boys; the interaction between PTB and sex was significant. Such an interaction between PTB and sex was not seen for asthma. No evident associations were observed between LBW, high birthweight, postterm birth, SGA, or LGA and wheeze or asthma. CONCLUSIONS This is the first study in Japan to show that PTB, but not LBW or SGA, was significantly positively associated with childhood wheeze and asthma.

Abstract
The vital role of folic acid is to reduce the risk of having a neonate afflicted with neural tube defects. The prevalence of neural tube defects (myelomeningocele and anencephaly) has been reported in an incomplete form over the last 40 years in Japan. We aimed to evaluate the total number of neural tube defects including those delivered or terminated, to clarify the proportion of those terminated, and to internationally compare their prevalence. Through information on >311 000 deliveries obtained from 262 hospitals/clinics for 2 years of 2014 and 2015, we identified that the rate of total neural tube defects (termination of pregnancy, live births and stillbirths) was 8.29 per 10 000 deliveries for the year 2014 and was 8.72 for 2015, which were 1.5 and 1.6 times higher than the respective values (live births and stillbirths) reported. It is also observed that the ratio of the total number of myelomeningocele (termination of pregnancy, live births, and stillbirths) to that of anencephaly was approximately 1:1.2, that a half of pregnancies afflicted with neural tube defects were terminated, and that the proportion of termination of pregnancy due to myelomeningocele and due to anencephaly was 20% and 80%, respectively. Internationally, the real prevalence of neural tube defects in Japan was comparatively high, ranking fifth among the seven developed countries. In conclusion, the real prevalence of total neural tube defects was approximately 1.5 times higher than that currently reported by the Japan Association of Obstetricians and Gynecologists.

Abstract
The Hayabusa2 spacecraft arrived at the near-Earth carbonaceous asteroid 162173 Ryugu in 2018. We present Hayabusa2 observations of Ryugu's shape, mass, and geomorphology. Ryugu has an oblate "spinning top" shape, with a prominent circular equatorial ridge. Its bulk density, 1.19 ± 0.02 grams per cubic centimeter, indicates a high-porosity (>50%) interior. Large surface boulders suggest a rubble-pile structure. Surface slope analysis shows Ryugu's shape may have been produced from having once spun at twice the current rate. Coupled with the observed global material homogeneity, this suggests that Ryugu was reshaped by centrifugally induced deformation during a period of rapid rotation. From these remote-sensing investigations, we identified a suitable sample collection site on the equatorial ridge.

Search for γ-Ray Line Signals from Dark Matter Annihilations in the Inner Galactic Halo from 10 Years of Observations with H.E.S.S. PHYSICAL REVIEW LETTERS 2018; 120:201101.

Abstract
Spectral lines are among the most powerful signatures for dark matter (DM) annihilation searches in very-high-energy γ rays. The central region of the Milky Way halo is one of the most promising targets given its large amount of DM and proximity to Earth. We report on a search for a monoenergetic spectral line from self-annihilations of DM particles in the energy range from 300 GeV to 70 TeV using a two-dimensional maximum likelihood method taking advantage of both the spectral and spatial features of the signal versus background. The analysis makes use of Galactic center observations accumulated over ten years (2004-2014) with the H.E.S.S. array of ground-based Cherenkov telescopes. No significant γ-ray excess above the background is found. We derive upper limits on the annihilation cross section ⟨σv⟩ for monoenergetic DM lines at the level of 4×10^{-28} cm^{3} s^{-1} at 1 TeV, assuming an Einasto DM profile for the Milky Way halo. For a DM mass of 1 TeV, they improve over the previous ones by a factor of 6. The present constraints are the strongest obtained so far for DM particles in the mass range 300 GeV-70 TeV. Ground-based γ-ray observations have reached sufficient sensitivity to explore relevant velocity-averaged cross sections for DM annihilation into two γ-ray photons at the level expected from the thermal relic density for TeV DM particles.

Abstract
The parietal epithelium of the Bowman's capsule in normal human kidney was studied by scanning electron microscopy. Stereoscopic scanning electron microscopy showed clearly that the Bowman's capsule, cut in half by a razor blade, was depressed hemispherically and coated with a flat layer of polygonal epithelial cells. The epithelial cell had a round, slightly elevated, and eccentrically located nuclear portion, and extended flat cytoplasmic layer from it toward the periphery. Tiny cytoplasmic projections, microvilli, were seen in varying degrees on the surface. One or two thin and long cilia were occasionally present around the nuclear portion.

Abstract
The present case-control study examined the relationship between IL5RA SNPs and eczema in young adult Japanese women. Cases and control subjects were selected from pregnant women who participated in the baseline survey of the Kyushu Okinawa Maternal and Child Health Study, which is an ongoing prebirth cohort study. Cases comprised 188 women with eczema in the previous 12 months as defined according to the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC), regardless of the presence of a doctor's diagnosis of atopic eczema. Control subjects comprised 1130 women without eczema as defined according to the ISAAC criteria who also had not been diagnosed with atopic eczema by a doctor. Compared with the AA genotype of IL5RA SNP rs17881144, the AT genotype, but not the TT genotype, was significantly associated with a decreased risk of eczema. The ATTAGA haplotype and the GTAGCA haplotype of rs17882210, rs3804797, rs334809, rs9831572, rs6771148 and rs17881144 were significantly associated with an increased risk of eczema. In contrast, the GCTGCA haplotype was significantly related to a decreased risk of eczema. Multiplicative interactions between IL5RA SNPs rs334809 and rs17881144 and smoking with respect to eczema were marginally significant (P = 0.07 and 0.07, respectively). This is the first study to show significant associations between IL5RA SNP rs17881144, the ATTAGA haplotype, the GTAGCA haplotype, and the GCTGCA haplotype and eczema. Smoking may modify the relationships between SNPs rs334809 and rs17881144 and eczema.

Abstract
Three previous genetic association studies conducted in Korea and China investigated the relationship between IL3 single nucleotide polymorphism (SNP) rs40401 and asthma, but their results were inconsistent. We examined this relationship and the possibility of an interaction between IL3 SNP rs40401 and smoking in young adult Japanese women. Included were 89 women who met the criteria of the European Community Respiratory Health Survey (ECRHS) for asthma. Control subjects were 700 women without asthma according to the ECRHS criteria who had not been diagnosed with asthma and/or allergic rhinitis by a doctor and/or who had not met the criteria of the International Study of Asthma and Allergies in Childhood for rhinoconjunctivitis. A significant positive association was found between SNP rs40401 and the risk of asthma, with the TT genotype as the reference under the additive model: the adjusted odds ratio was 1.39 (95% CI: 1.004-1.93). The positive association was not statistically significant in any other genetic model. Compared with subjects with the TT or TC genotype of SNP rs40401 who had never smoked, those with the CC genotype who had ever smoked had a significantly increased risk of asthma: the adjusted OR was 2.67 (95% CI: 1.23-5.79); the additive interaction, but not the multiplicative interaction, was significant. This study suggests that IL3 SNP rs40401 is significantly associated with the risk of asthma in young adult Japanese women and reveals that the combination of ever smoking and having the CC genotype of IL3 SNP rs40401 is significantly positively associated with asthma.

Abstract
OBJECTIVE To examine the relationship between the intake of dairy products and calcium and the prevalence of depressive symptoms during pregnancy. DESIGN Cross-sectional study. SETTING Kyushu Okinawa Maternal and Child Health Study (KOMCHS). SAMPLE A cohort of 1745 pregnant Japanese women. METHODS Dietary intake during the preceding month was assessed using a self-administered diet history questionnaire. Scores of 16 or higher on the Center for Epidemiologic Studies Depression Scale denoted depressive symptoms. Adjustment was made for age, gestation, region of residence, number of children, family structure, history of depression, family history of depression, smoking, secondhand smoke exposure at home and at work, job type, household income, education, and body mass index. In our analyses regarding dairy products in general, adjustment was also made for fish intake; in our analysis regarding calcium, adjustment was also made for the intake of saturated fatty acids, eicosapentaenoic acid plus docosahexaenoic acid, and vitamin D. MAIN OUTCOME MEASURES Depressive symptoms during pregnancy. RESULTS Higher intake levels of yogurt and calcium were independently related to a lower prevalence of depressive symptoms during pregnancy: the adjusted odds ratios between extreme quartiles were 0.69 (95% CI 0.48-0.99, P for trend = 0.03) and 0.59 (95% CI 0.40-0.88, P for trend = 0.006), respectively. No relationships were observed between the intake of all dairy products, milk, or cheese and depressive symptoms during pregnancy. CONCLUSIONS The current results suggest that a higher intake of yogurt and calcium may be associated with a lower prevalence of depressive symptoms during pregnancy.

Influence of losartan intake on the circadian rhythm of melatonin secretion in humans. DIE PHARMAZIE 2014; 69:192-197. [PMID: 24716408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/03/2023]
Abstract
It has been reported that losartan, an angiotensin II receptor blocker, alters the circadian rhythm of melatonin secretion and significantly reduces melatonin production. However, this finding has been confirmed at the animal experiment level only, and there are no reports of studies in humans. Therefore, we performed this study to confirm the reproducibility of the aforementioned findings of animal experiments in humans. Ten male subjects who were in good general health and free from any medical condition were recruited for this study. After a preliminary observation period of 7 days, the subjects received oral losartan treatment, 50 mg daily for 7 days. Blood samplings for measurement of the plasma melatonin concentrations were performed on day 7 of the preliminary observation period and day 7 of the losartan treatment period. The circadian rhythm of melatonin secretion after the 7-day treatment with losartan showed no significant difference from that recorded before the losartan administration. The significant decrease of the home blood pressure was observed on the afternoons. The blood samples showed significant decrease of the serum sodium and uric acid levels, along with a significant increase of the serum potassium level. The pharmacological actions of losartan at the ordinarily used clinical dose level were confirmed in humans, however, no significant inhibitory effect of the drug on melatonin secretion could be confirmed. These results are expected to be useful for guiding the proper use of angiotensin II receptor blockers.

Abstract
Abstract Although several recent reports have discussed the similarities between human parvovirus B19 (HPV-B19) infection and systemic lupus erythematosus (SLE), the relationship between these conditions has not been established owing to the small number of patients investigated. In 1998-1999, an outbreak of Erythema infectiosum occurred close to our hospital, enabling us to investigate the clinical, hematological, and serological findings, including serum complement and antinuclear antibodies (ANA), in 22 patients with acute HPV-B19 infection. The principal symptoms included rash (86.3%), edema (59%), arthralgia (45.4%) and fever (31.8%). Lymphadenopathy was seen in three of the 22 cases. The laboratory findings showed high incidences of leukopenia (50%), hypocomplementemia (95%), and ANA (64.7%). At the time of disease onset, patients with acute HPV-B19 infection presented with features which were similar to those of SLE. The possibility of HPV-B19 infection should therefore be considered in patients presenting with SLE-like features.

Abstract
Epidemiological evidence on the relationship between vitamin D receptor (VDR) polymorphisms and periodontal disease is inconsistent. We investigated associations between four VDR single-nucleotide polymorphisms (SNPs) including rs731236 (TaqI), rs7975232 (ApaI), rs1544410 (BsmI) and rs2228570 (FokI), and the risk of periodontal disease among young Japanese women. Cases included 131 women who had at least one tooth with a probing depth of 3.5 mm or deeper. Controls included 1019 women without periodontal disease. Adjustment was made for age, region of residence, education, toothbrushing frequency and use of an interdental brush. Compared with the AA genotype of SNP rs731236, the GG genotype had a significantly increased risk of periodontal disease: the adjusted OR was 3.68 (95% confidence interval: 1.06-12.78). There were no significant relationships between SNPs rs7975232, rs1544410 or rs2228570 and periodontal disease. None of the haplotypes were significantly related to periodontal disease. Compared with subjects with the AA or AG genotype of SNP rs731236 who had never smoked, those with the GG genotype who had ever smoked had a significantly increased risk of periodontal disease; nevertheless, neither multiplicative nor additive interaction was significant. The additive interaction between SNP rs7975232 and smoking was significant, although the multiplicative interaction was not statistically significant. No multiplicative or additive interactions were observed between the other SNPs and smoking. Our results indicated that VDR SNP rs731236 might be associated with periodontal disease. In addition, we present new evidence for a biological interaction between VDR SNP rs7975232 and smoking that affects periodontal disease.

Abstract
Epidemiological research on the relationship between single nucleotide polymorphisms (SNPs) in the IL4Rα gene and eczema is sparse. We investigated the associations between IL4Rα SNPs rs1805011, rs1805015 and rs1801275 and risk of eczema in young adult Japanese women. Included were 188 women who met the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC) for eczema. Controls were 635 women without eczema according to the ISAAC criteria who also had not been diagnosed with asthma, atopic eczema and/or allergic rhinitis by a doctor. Adjustment was made for age, region of residence, number of children, smoking and education. Under the additive model, SNP rs1805011 was significantly related to eczema: the adjusted OR was 0.55 (95% CI: 0.31-0.99). SNP rs1805015 was significantly associated with eczema in the additive and dominant models: the adjusted ORs were 0.55 (95% CI: 0.30-0.98) and 0.55 (95% CI: 0.30-0.997), respectively. There was no significant association between SNP rs1801275 and eczema. None of the haplotypes were significantly related to eczema. Significant associations between SNPs rs1805011 and rs1805015 and eczema were reported in women who had never smoked, but not in those who had ever smoked; the multiplicative interactions, however, were not significant. This is the first study to demonstrate significant associations between IL4Rα SNPs rs1805011 and rs1805015 and eczema. We do not find evidence for interactions affecting eczema between IL4Rα SNPs and smoking.

Abstract
BACKGROUND AND OBJECTIVE Studies reporting on the association between smoking and periodontal disease have mostly focused on active smoking. The purpose of this study was to examine the relationships between active smoking and exposure to second-hand smoke at home and at work and the prevalence of periodontal disease among young Japanese women. MATERIAL AND METHODS Study subjects were 1167 postpartum women with a mean age of 31.5 years. Information on smoking and potential confounding factors was obtained through a self-administered questionnaire. Partial-mouth recording was used to determine probing pocket depth at six sites per tooth for six teeth in the mouth. Periodontal disease was defined as positive if a woman had at least one tooth with a probing pocket depth of 3.5 mm or deeper. Adjustment was made for age, region of residence, household income, education, toothbrushing frequency and use of an interdental brush. RESULTS Compared with never smoking, ever smoking was independently positively associated with the prevalence of periodontal disease: the adjusted odds ratio was 1.56 (95% confidence interval: 1.02-2.36). There was a marginally significant positive dose-response relationship between pack-years of smoking and the prevalence of periodontal disease (p for linear trend = 0.08). No material associations were observed between second-hand smoke exposure at home or at work and periodontal disease. CONCLUSION Our findings suggest that active smoking, but not passive smoking, might be associated with an increased prevalence of periodontal disease among young women in Japan.

Abstract
BACKGROUND Interleukin (IL) 4 plays a critical role in immune responses by acting as a growth factor for type 2 helper T cells and inducing immunoglobulin (Ig) class switching to IgE. Epidemiological evidence of the relationship between single-nucleotide polymorphisms (SNPs) in IL4 and asthma is inconsistent. OBJECTIVES We examined the association between the IL4 SNPs rs2243250, rs2070874, rs2227284, and rs2243290 and asthma in young adult Japanese women. METHODS The study population comprised 89 women who met the criteria of the European Community Respiratory Health Survey (ECRHS) for asthma. The control group comprised 1281 nonasthmatic women (ECRHS criteria) who had not been diagnosed with asthma by a physician. Adjustment was made for age, region of residence, presence of older siblings, smoking, and education. RESULTS Compared with the AA genotype of rs2243290, the AC genotype, but not the CC genotype, was significantly associated with a reduced risk of asthma: the adjusted odds ratio for the AC genotype was 0.62 (95% CI, 0.39-0.996). No evident relationships were found between rs2243250, rs2070874, or rs2227284 and asthma. None of the haplotypes were significantly associated with asthma. No significant interactions were found between the 4 SNPs under study and smoking with respect to the risk of asthma. CONCLUSIONS Ours is the first study in a non-Western population to show that the IL4 SNP rs2243290 was significantly associated with the risk of asthma. Smoking did not significantly modify the gene-disease associations under study.

Abstract
The information on the stability of medications is important to secure their quality. There is, however, little information about the stability of medications which assume to be kept by patients and customers. We previously showed that a delay in drug release occurs in some over-the-counter (OTC) drugs following storage in a high temperature, high humidity environment. In this study we prepared model tablet formulations containing an active ingredient and excipients to investigate the cause of this delayed release. The results reveal that delayed release occurs in preparations compounded with acetaminophen (AA) as the active ingredient and erythritol (ET) and crospovidone (CP) as excipients. In addition, ET deliquesces in a high humidity environment, then incorporates other particles during room temperature storage to form an aggregate. SEM observations and micropore distribution measurements conducted on OTC tablets that exhibit delayed release revealed that the number of intraparticle pores decreased after storage under high temperature, high humidity conditions. Thus, the delayed release by these pharmaceutical product formulations may be due to a change in the micropore structure both on the surface and within the particles, thereby decreasing the solvent infiltration pathways leading to the interior of the preparation.

Abstract
SETTING Epidemiological evidence for the associations between intake of dairy products, calcium and vitamin D and allergic disorders has been inconsistent. OBJECTIVES To examine such associations in Japan. DESIGN This cross-sectional study enrolled 1745 pregnant women. The definitions of wheeze and asthma were based on European Community Respiratory Health Survey criteria, whereas those of eczema and rhinoconjunctivitis were based on International Study of Asthma and Allergies in Childhood criteria. Information on dietary factors was collected using a validated self-administered diet history questionnaire. RESULTS Intake of total dairy products, milk, yoghurt, cheese and calcium was not related to the prevalence of wheeze, asthma, eczema or rhinoconjunctivitis. After adjustment for potential confounders, vitamin D intake was found to be independently positively associated with the prevalence of asthma: the adjusted ORs for asthma in the first, second, third and fourth quartiles were respectively 1.00 (reference), 1.26 (95%CI 0.65-2.50), 2.08 (95%CI 1.13-3.94), and 1.82 (95%CI 0.97-3.51, P for trend = 0.03). There were no relationships between vitamin D consumption and the prevalence of wheeze, eczema or rhinoconjunctivitis. CONCLUSIONS These findings suggest that vitamin D intake may be positively related to the prevalence of asthma in young adult Japanese women.

SETTING Multiple A disintegrin and metalloprotease 33 (ADAM33) single nucleotide polymorphisms (SNPs) have been shown to be associated with asthma, but results have been inconsistent. OBJECTIVES To examine the association between ADAM33 SNPs rs2787094, rs628977, rs2280089, rs2280090, rs2280091, rs2853209, rs528557 and rs612709 and asthma in young adult Japanese women, and to perform haplotype analyses and assess interactions between SNPs and smoking. DESIGN A total of 89 cases who met the criteria of the European Community Respiratory Health Survey (ECRHS) for asthma were included in the study. Control subjects were 1281 women without asthma, as per ECRHS criteria, who had not been diagnosed with asthma by a doctor. Adjustment was made for age, region of residence, presence of older siblings, smoking and education. RESULTS Under a co-dominant model, the AA genotype of the rs612709 SNP was significantly positively associated with asthma compared with the GG genotype: the adjusted OR was 4.27 (95%CI 1.49-12.25). A significant positive relationship was found between the CCGGAAGA haplotype and asthma. Interactions between SNPs rs628977 and rs528557 and smoking were marginally significant (P = 0.09 and 0.095, respectively). CONCLUSIONS ADAM33 SNP rs612709 and the CCGGAAGA haplotype may be associated with asthma. Smoking may modify the associations between SNPs rs628977 and rs528557 and asthma.

Abstract
A compact cubic-anvil high-pressure device was developed for in situ neutron powder diffraction studies. In this device, a cubic shaped pressure medium is compressed by six anvils, and neutron beams pass through gaps between the anvils. The first high-pressure experiment using this device was conducted at J-PARC and clearly showed the neutron diffraction patterns of Pb. Combining the cubic-anvil high-pressure device with a pulsed neutron source will prove to be a useful tool for neutron diffraction experiments.

Abstract
BACKGROUND Neuromyelitis optica (NMO) is a demyelinating syndrome characterized by myelitis and optic neuritis. Detection of anti-NMO immunoglobulin G antibody that binds to aquaporin-4 (AQP4) water channels allows the diagnosis of a limited form of NMO in the early stage with myelitis, but not optic neuritis. However, the detailed clinicopathologic features and long-term course of this limited form remain elusive. METHODS We investigated 8 patients with the limited form of NMO with myelitis in comparison with 9 patients with the definite form. RESULT All patients with limited and definite form showed uniform relapsing-remitting courses, with no secondary progressive courses. Pathologic findings of biopsy specimens from the limited form were identical to those of autopsy from the definite form, demonstrating extremely active demyelination of plaques, extensive loss of AQP4 immunoreactivity in plaques, and diffuse infiltration by macrophages containing myelin basic proteins with thickened hyalinized blood vessels. Moreover, the definite form at the nadir of relapses displayed significantly higher amounts of the inflammatory cytokines interleukin (IL)-1beta and IL-6 in CSF than the limited form and multiple sclerosis. CONCLUSION This consistency of pathologic findings and uniformity of courses indicates that aquaporin 4-specific autoantibodies as the initiator of the neuromyelitis optica (NMO) lesion consistently play an important common role in the pathogenicity through the entire course, consisting of both limited and definite forms, and NMO continuously displays homogeneity of pathogenic effector immune mechanisms through terminal stages, whereas multiple sclerosis should be recognized as the heterogeneous 2-stage disease that could switch from inflammatory to degenerative phase. This report is a significant description comparing the pathologic and immunologic data of limited NMO with those of definite NMO.

Abstract
AIM The aim of this study was to compare the effect of continuation or discontinuation of glimepiride upon starting insulin therapy in type 2 diabetic patients poorly controlled with sub-maximal glimepiride. METHODS This 48-week, randomized, observational, parallel-group study consisted of a 24-week screening period and a 24-week intervention period. During the screening period, we unified the sulfonylureas to glimepiride at 3mg/day for 8 weeks, and started biphasic insulin aspart 30 (Asp30Mix) once-daily injections for 16 weeks. At the start of the intervention period, we stepped up once- to twice-daily insulin injection and randomized the 26 patients into either continuation of glimepiride group (CONT, n=14) or discontinuation of glimepiride group (DISCON, n=12). The Asp30Mix dose-adjustment algorithm was used in both groups. HbA1C, plasma glucose, insulin daily dose, body weight, and number of hypoglycaemic episodes were evaluated. RESULTS At the end of the study, HbA1C improved in CONT more than in DISCON (P<0.01), and daily dose of Asp30Mix was less in CONT than DISCON (P<0.05). Body weight and the numbers of hypoglycaemic episodes were similar between the two groups. CONCLUSION Continuing glimepiride (sulfonylureas) allows a better glycaemic control with less insulin daily dose compared with discontinuing glimepride.

Abstract
AIMS/HYPOTHESIS Ectopic activation of hedgehog (HH) signalling in pancreas induces various abnormal morphogenetic events in the pancreas. This study analysed the dose-dependent requirement of patched homologue 1 (PTCH1), a negative regulator of HH signalling on pancreatic development. METHODS We used a recessive spontaneous mutant mouse denoted as mes which carries a mutated Ptch1 resulting in deletion of the most carboxy-terminal cytoplasmic domain of the PTCH1 protein. In this study, we analysed pancreatic morphology in Ptch1 ( +/+ ), Ptch1 ( +/mes ), Ptch1 (+/-), Ptch1 ( mes/me ) (s) and Ptch1 (-/mes ) mouse embryos, as well as the islet mass in adult Ptch1 (+/+), Ptch1 (+/mes ) and Ptch1 (+/-) mice. RESULTS Until embryonic day (E) 12.5, no obvious abnormality of pancreas was observed in any of the Ptch1 mutants. The levels of PDX1 and glucagon were also not evidently different among the mice genotypes studied. Thereafter, morphological abnormalities appeared in the Ptch1 mutant mice. The beta, alpha and exocrine cell masses decreased at E18.5 in parallel with increased HH signalling, with beta cell mass showing the highest sensitivity to HH signalling with a significant decrease even in Ptch1 (+/mes ) mice. Adult Ptch1 (+/-) mice also showed a significant decrease in beta cell mass compared with wild-type mice. CONCLUSIONS/INTERPRETATION Our findings indicate that the carboxy-terminal domain of Ptch1 is essential for pancreatic development. In addition, the loss of Ptch1 function decreases both the endocrine and exocrine cell mass in a dose-dependent manner, with beta cells particularly sensitive to changes in HH signalling.

Abstract
BACKGROUND It has been hypothesized that increased consumption of n-6 polyunsaturated fatty acids and decreased consumption of n-3 polyunsaturated fatty acids have contributed to the recent increased prevalence of asthma. OBJECTIVES The present cross-sectional study examined the association of intake of specific types of fatty acids with the prevalence of asthma symptoms using data from the Ryukyus Child Health Study. METHODS Study subjects were 25,033 schoolchildren aged 6-15 years in Okinawa, Japan. Symptoms of wheeze and asthma were defined according to diagnostic criteria from the International Study of Asthma and Allergies in Childhood. Information on dietary factors was collected using a self-administered brief diet history questionnaire for children. Adjustment was made for age, sex, number of siblings, smoking in the household, body mass index, paternal and maternal history of allergic diseases, and paternal and maternal educational level. RESULTS Intake of polyunsaturated fatty acids, n-3 and n-6 polyunsaturated fatty acids and linoleic acid (18:2 n-6) was independently associated with an increased prevalence of wheeze--the multivariate odds ratios for the highest quintile were 1.19 (95% confidence interval [CI], 1.05-1.35), 1.17 (95% CI, 1.03-1.34), 1.19 (95% CI, 1.04-1.35), and 1.20 (95% CI, 1.06-1.37), respectively. There was no measurable relationship of consumption of alpha-linolenic (18:3 n-3), eicosapentaenoic (20:5 n-3), docosahexaenoic (22:6 n-3) or arachidonic acid (20:4 n-6) or the ratio of n-3 to n-6 polyunsaturated fatty acids with the prevalence of wheeze. Consumption of total fat, saturated fatty acids, monounsaturated fatty acids and cholesterol were not evidently related to wheeze. No material dose-response association was found between the intake of any of the types of fatty acids considered and the prevalence of asthma. CONCLUSIONS The findings suggest that consumption of both n-3 and n-6 polyunsaturated fatty acids, especially linoleic acid, may be associated with an increased prevalence of wheeze.

Abstract
Expression of sonic hedgehog (Shh), a morphogen for the gastric fundic glands, is reduced in the atrophic mucosa that develops in association with Helicobacter pylori infection, resulting in impaired differentiation of the fundic gland cells, increased expression of trefoil factor family 2 (TFF2) and the formation of spasmolytic polypeptide (SP)-expressing metaplasia (SPEM), a preneoplastic lesion. However, it is still unresolved whether H. pylori-induced inflammation and the resultant reduction in parietal cell number or reduced parietal cell function per se reduces Shh expression. The present study was designed to clarify the expression of Shh and TFF2 in the context of parietal cell dysfunction in the absence of inflammation, using histamine H(2) receptor-knockout (H(2)R-null) mice and an acid exposure model. Age-matched H(2)R-null mice and wild-type (WT) mice were used. The expression of Shh and TFF2 mRNA was quantified by quantitative RT-PCR. Immunohistochemistry was also performed to detect the expression of Shh, TFF2 and cell markers. To study the effects of acid exposure, HCl solution was administered to the animals. The H(2)R-null mice exhibited higher gastric pH, increased TFF2 expression and reduced Shh expression. Impaired mucous neck-to-zymogenic cell differentiation was observed in the H(2)R-null mice. Furthermore, Shh expression increased in the presence of gastric acid and showed a significant correlation with gastric surface pH. In conclusion, our results suggest that persistent parietal cell dysfunction alone (suppressed gastric acid secretion), in the absence of inflammation or parietal cell loss caused by H. pylori infection, may be sufficient to down-regulate Shh expression in TFF2-overexpressing preneoplastic lesions of the gastric fundus. Since exposure to acid restored fundic Shh expression, appropriate gastric acid secretion may play an important role in the morphogen dynamics involved in the maintenance of gastric fundic gland homeostasis.
