Abstract	Purpose To investigate the 2-year healing rate of macular edema (ME) secondary to branch retinal vein occlusion (BRVO) treated initially with intravitreal ranibizumab (IVR) and later combined with other treatment as needed, and the characteristics of refractory cases. Methods 130 patients (130 eyes) with BRVO-ME who received IVR initially were studied. Anti-vascular endothelial growth factor drug was additionally administered when ME relapsed or persisted. Photocoagulation was performed when the non-perfusion area (NPA) was ≥5 disc diameter (DD), and/or when ME relapsed due to microaneurysm. Patients were classified into a healed group [ME resolved in <2 years or mild ME remained without best-corrected visual acuity (BCVA) loss for ≥6 months] or refractory group (ME persisted for ≥2 years). Results 110 eyes were classified into the healed group, and 20 eyes into the refractory group. The healed group and refractory group had, respectively, mean follow-up periods of 21.2 and 37.4 months, and frequencies of NPA ≥5 DD of 55.5 and 25.0% (p = 0.015). In the healed group, mean BCVA (logMAR) improved significantly compared to baseline in all the periods until 24 months after treatment initiation and at the last visit (p<0.001). In the refractory group, mean BCVA improved significantly compared to baseline until 12 months after treatment initiation (p<0.05 for all periods), but was not significantly different at 18 or 24 months or at the last visit. Conclusion In patients with BRVO-ME treated initially with IVR and later given additional treatments as needed, the healing rate was 84.6%. In eyes that healed within 2 years, BCVA improved relative to baseline throughout 24 months and at the last visit. In refractory eyes, BCVA improved only until 12 months, and thereafter deteriorated to baseline level at the last examination.

Abstract	Abstract Studies of the usefulness of transverse right ventricular (RV) shortening are limited. We retrospectively analyzed the CMR images of 67 patients (age: 50.8 ± 19.0 years; men: 53.7%; Control: n = 20, Overloaded RV (atrial septal defect): n = 15, Constricted RV (pericarditis): n = 17, Degenerated RV (arrhythmogenic right ventricular cardiomyopathy): n = 15) (all enrolled consecutively for each disease) in a single center. We defined RV longitudinal (fractional longitudinal change: FLC) and transverse (fractional transverse change: FTC) contraction parameters. We assessed the FTC/FLC (T/L) ratio on four-chamber cine CMR views and compared the four groups regarding the fractional parameters. FTC had a stronger correlation (R2 = 0.650; p < 0.001) with RV ejection fraction than that with FLC (R2 = 0.211; p < 0.001) in the linear regression analysis. Both FLC and FTC were significantly lower in the Degenerated RV and Constricted RV groups compared with those in the Control and Overloaded RV groups. The T/L ratio was significantly lower in the Degenerated RV group (p = 0.008), while the Overloaded RV (p = 0.986) and Constricted RV (p = 0.582) groups had preserved T/L ratios, compared with the Control group. Transverse shortening contributes to RV function more significantly compared with longitudinal contraction. Impaired T/L ratios may reflect RV myocardial degeneration. RV fractional parameters may help precisely understand RV dysfunction.

Abstract	Background: The use of mobile health has increased worldwide, but along with its increased utilization comes the risk of the digital divide, inequity in access to information and communications technologies, exerting greater influence on health inequity caused by socioeconomic determinants of health. There is a growing need to investigate whether the digitization of existing health interventions has a risk of worsening the health gap. Methods: We investigated the attitudes of mothers and pregnant women toward digitization of the Maternal and Child Health Handbook (MCHH), a popular personal health record (PHR) used by almost every pregnant woman or mother in Japan, using a cross-sectional survey. We determined sociodemographic factors associated with favorable opinions toward digitization using a multivariate regression model. We then grouped the participants using partitioning around medoids clustering, a machine-learning approach, to interpret their varying attitudes toward digitization in light of their sociodemographic characteristics as well as their affinity toward the paper MCHH. Findings: Higher income and educational level, older age, and less reliance on the MCHH were significantly associated with favorable opinion toward digitization. Clustering analysis identified four latent clusters. The cluster with the highest socioeconomic status (SES) was the most favorable toward digitization, while two clusters with the lowest SES, one of which relied heavily on the paper MCHH, were less favorable of digitization compared to the high SES cluster. The final cluster was comprised of mothers with the experience of raising multiple children and did not rely heavily on the MCHH. Interpretation: Our study identified a socioeconomic divide in opinions toward digitization of an existing health intervention. A hasty digitization may result in an unbalanced uptake of the digitized health intervention among different social classes.

Abstract	To elucidate changes in the defensive traits of tree seedlings under global environmental changes, we evaluated foliar defensive traits of the seedlings of successional trees, such as beech, oak, and magnolia grown in a natural-light phytotron. Potted seedlings were grown under the combination of two CO 2 concentrations (360 vs. 720 ppm) and two nitrogen (N) treatments (4 vs. 15 kg N ha −1 yr −1 ) for two growing seasons using quantitative chemical analyses and anatomical method. We hypothesized that the effects of CO 2 and N depend on the successional type, with late successional species providing greater defense of their leaves against herbivores, as this species exhibits determinate growth. Beech, a late successional species, responded the most to both elevated CO 2 concentration (eCO 2 ) and high N treatment. eCO 2 and low N supply enhanced the defensive traits, such as the high leaf mass per area (LMA), high carbon to N ratio (C/N ratio), and increase in the concentrations of total phenolic and condensed tannin in agreement with the carbon–nutrient balance (CNB) hypothesis. High N supply decreased the C/N ratio due to the high N uptake in beech leaves. Oak, a mid–late successional species, exhibited different responses from beech: eCO 2 enhanced the LMA, C/N ratio, and concentration of total phenolics of oak leaves, but only condensed tannin increased under high N supply. Magnolia did not respond to all treatments. No interactive effects were observed between CO 2 and N supply in all species, except for the concentration of total phenolics in oak. Although the amounts of phenolic compounds in beech and oak varied under eCO 2 and high N treatments, the distribution of these compounds did not change. Our results indicate that the changes in the defensive traits of forest tree species under eCO 2 with N loading are related to the successional type.

Abstract	Despite concerns raised on the inequality in healthcare provision in Japan, little is known about the factors that hinder candidates' application to medical schools. A nationwide cross-sectional survey was conducted to identify the impact of economic factors and living place on students' choice of and preparation for medical school. The survey was administered to high school teachers with career advisory roles, as they support and likely influence students' choice and decision on this matter. Responses totaling 1,094 were obtained from 1,746 high schools across Japan. The ratio of high schools with two or more students enrolled in medical schools every year is higher in private schools, those with high tuition, and those located in big cities. Approximately 66.8% of the respondents agreed that "It is difficult for students in economically disadvantaged families to enroll in medical schools;" 42.0% agreed that "Some students gave up on aspiring to enter medical schools because they could not afford it," and 61.2% agreed that "Students living in urban areas are more likely to enroll in medical schools." When asked about the percentage of students attending prep school among those aspiring for a medical career, significantly more respondents from private versus public high schools answered "80% or more." When asked about the percentage of parents who are doctors or dentists among students aspiring for a medical career, significantly more respondents from private versus public high schools answered "50% or more." The results suggest that students from lower-income families and those living in rural areas are more likely to be disadvantaged when choosing a medical career (because of financial difficulties) than those who live in urban areas and come from wealthier families. The results imply that economic and geographical divides in medical admission are reflected in high school teachers' perception of and support provided to students.

Abstract	In this study, we used reporter gene assays in COS-1 cells to examine the activation of rat pregnane X receptor (PXR), rat constitutive androstane receptor (CAR) and rat peroxisome-proliferator activated receptor (PPAR)α by pyrethroid pesticides, and to understand the effects of metabolic modification on their activities. All eight pyrethroids tested in this study showed rat PXR agonistic activity; deltamethrin was the most potent, followed by cis-permethrin and cypermethrin. However, when the pyrethroids were incubated with rat liver microsomes, their rat PXR activities were decreased to various extents. Cis- and trans-permethrin showed weak rat CAR agonistic activity, while the other pyrethroids were inactive. However, fenvalerate showed dose-dependent inverse agonistic activity toward rat CAR, and this activity was reduced after metabolism. None of the pyrethroids showed rat PPARα agonistic activity, but a metabolite of cis-/trans-permethrin and phenothrin, 3-phenoxybenzoic acid, activated rat PPARα. Since PXR, CAR and PPARα regulate various xenobiotic/endobiotic-metabolizing enzymes, activation of these receptors by pyrethroids may result in endocrine disruption due to changes of hormone-metabolizing activities.

Abstract	KEY MESSAGE : The black locust is adapted to elevated [CO â ] through changes in nitrogen allocation characteristics in leaves. The black locust (Robinia pseudoacacia L.) is an invasive woody legume within Japan. This prolific species has a high photosynthetic rate and growth rate, and undergoes symbiosis with Nâ-fixing micro-organisms. To determine the effect of elevated COâ concentration [COâ] on its photosynthetic characteristics, we studied the chlorophyll (Chl) and leaf nitrogen (N) content, and the leaf structure and N allocation patterns in the leaves and acetylene reduction activity after four growing seasons, in R. pseudoacacia. Our specimens were grown at ambient [COâ] (370Â Î¼molÂ molâ»Â¹) and at elevated [COâ] (500Â Î¼molÂ molâ»Â¹), using a free air COâ enrichment (FACE) system. Net photosynthetic rate at growth [COâ] (A gáµ£âwââ) and acetylene reduction activity were significantly higher, but maximum carboxylation rate of RuBisCo (V câââ), maximum rate of electron transport driving RUBP regeneration (J âââ), net photosynthetic rate under enhanced COâ concentration and light saturation (A âââ), the N concentration in leaf, and in leaf mass per unit area (LMA) and ribulose-1,5-bisphosphate carboxylase oxygenase (RuBisCo) content were significantly lower grown at elevated [COâ] than at ambient [COâ]. We also found that RuBisCo/N were less at elevated [COâ], whereas Chl/N increased significantly. Allocation characteristics from N in leaves to photosynthetic proteins, NL (Light-harvesting complex: LHC, photosystem I and II: PSI and PSII) and other proteins also changed. When R. pseudoacacia was grown at elevated [COâ], the N allocation to RuBisCo (NR) decreased to a greater extent but NL and N remaining increased relative to specimens grown at ambient [COâ]. We suggest that N remobilization from RuBisCo is more efficient than from proteins of electron transport (NE), and from NL. These physiological responses of the black locust are significant as being an adaptation strategy to global environmental changes.

Abstract	Phthalates are used in food packaging, and are transferred to foods as contaminants. In this study, we examined the hydrolytic metabolism of dimethyl phthalate (DMP), dibutyl phthalate (DBP) and di(2-ethylhexyl) phthalate (DEHP) by rat tissue microsomes. We found that carboxylesterase and lipase contribute differently to these activities. When DMP, DBP and DEHP were incubated with rat liver microsomes, DBP was most effectively hydrolyzed to the phthalate monoester, followed by DMP, and the activity toward DEHP was marginal. In contrast, small-intestinal microsomes exhibited relatively higher activity toward long-side-chain phthalates. Pancreatic microsomes showed high activity toward DEHP and DBP. Liver microsomal hydrolase activity toward DMP was markedly inhibited by bis(4-nitrophenyl)phosphate, and could be extracted with Triton X-100. The activity toward DBP and DEHP was partly inhibited by carboxylesterase inhibitor, and was partly solubilized with Triton X-100. Ces1e, Ces1d and Ces1f expressed in COS cells exhibited the highest hydrolase activity toward DBP, showing a similar pattern to that of liver microsomes. Ces1e showed activity towards DMP and DEHP. Pancreatic lipase also hydrolyzed DBP and DEHP. Thus, carboxylesterase and lipase contribute differently to phthalate hydrolysis: short-side-chain phthalates are mainly hydrolyzed by carboxylesterase and long-side-chain phthalates are mainly hydrolyzed by lipase.

Abstract	To evaluate water and nitrogen input via fog deposition, the fog water chemistry and deposition around a crater lake (Lake Mashu) in northern Japan were investigated in the growing seasons of trees (summer to autumn) in 2006â2012. The fog samples were collected using an active fog collector and droplet size distribution was measured with a droplet size spectrometer (FM-100). The visibility (VIS)âliquid water content of fog (LWC) relationship differed between summer and autumn. Large fog droplets decreased in autumn and the calculated LWC from FM-100 measurements (LWCobs) were lower than those in summer at the same VIS. Two empirical curves between LWCobs and VIS were obtained and used for better estimation of fog deposition. Fog deposition was calculated from LWC empirically derived from past VIS data and deposition velocity (Vd) estimated using wind speed and vegetation parameters. The mean pH of fog water was 4.6 and the percentage of samples of pH4.0 or more was 93%. Compared to previous literature of exposure experiments of acid mist on plants, fog acidity in this study did not seem to injure plant leaves. The water input via fog deposition accumulated for each growing season was estimated at 107â140mm, corresponding to 18â23% of the precipitation in the same period. Nitrogen deposition via fog deposition in a plant growing season was estimated at 26â30meqmâ2 (3.6â4.2kg Nhaâ1). As a long-term trend, NO3â concentration in fog water decreased significantly. However, the long-term trends of fog and nitrogen depositions were not clear.

Abstract	Fog deposition onto the cool-temperate deciduous forest around Lake Mashu in northern Japan was estimated by the inferential method using the parameterizations of deposition velocity and liquid water content of fog (LWC). Two parameterizations of fog deposition velocity derived from field experiments in Europe and numerical simulations using a detailed multi-layer atmosphere-vegetation-soil model were tested. The empirical function between horizontal visibility (VIS) and LWC was applied to produce hourly LWC as an input data for the inferential method. Weekly mean LWC computed from VIS had a good correlation with LWC sampled by an active string-fog collector. By considering the enhancement of fog deposition due to the edge effect, fog deposition calculated by the inferential method using two parameterizations of deposition velocity agreed with that computed from throughfall data. The results indicated that the inferential method using the current parameterizations of deposition velocity and LWC can provide a rough estimation of water input due to fog deposition onto cool-temperature deciduous forests. Limitations of current parameterizations of deposition velocity related to wind speed, evaporation loss of rain and fog droplets intercepted by tree canopies, and leaf area index were discussed.
