Abstract
The periodontal ligament (PDL) contains mesenchymal stem cells (MSCs) that can differentiate into osteoblasts, cementoblasts, and fibroblasts. Nevertheless, the distribution and characteristics of these cells remain uncertain. Gli1, an essential hedgehog signaling transcription factor, functions in undifferentiated cells during embryogenesis. Therefore, in the present study, the differentiation ability of Gli1+ cells was examined using Gli1-CreERT2/ROSA26-loxP-stop-loxP-tdTomato (iGli1/Tomato) mice. In 4-wk-old iGli1/Tomato mice, Gli1/Tomato+ cells were only slightly detected in the PDL, around endomucin-expressing blood vessels. These cells had proliferated over time, localizing in the PDL as well as on the bone and cementum surfaces at day 28. However, in 8-wk-old iGli1/Tomato mice, Gli1/Tomato+ cells were quiescent, as most cells were not immunoreactive for Ki-67. These cells in 8-wk-old mice exhibited high colony-forming unit fibroblast activity and were capable of osteogenic, chondrogenic, and adipogenic differentiation in vitro. In addition, after transplantation of teeth of iGli1/Tomato mice into the hypodermis of wild-type mice, Tomato fluorescence indicating the progeny of Gli1+ cells was detected in the osteoblasts and osteocytes of the regenerated bone. These results demonstrate that Gli1+ cells in the PDL were MSCs and could contribute to the alveolar bone regeneration.

Abstract
Symptom overlap between meibomian gland dysfunction (MGD) and dry eye (DE) makes it difficult to distinguish between these two conditions on the basis of symptoms alone. We searched for characteristic symptoms that might help to distinguish MGD from DE on the basis of a population-based study. Subjects comprised 311 residents of Takushima island (18 to 96 years), including 117 individuals with MGD and 114 with DE. Responses to a symptom-related questionnaire (19 items) were subjected to factor analysis, and univariate regression analysis was performed to identify ocular surface parameters associated with characteristic symptoms of MGD. Factor analysis revealed aggregation of symptoms according to three factors: Factor 1 related to Symptom Score, Factor 2 to DE, and Factor 3 to MGD. Symptoms associated with DE included 11 items, whereas the only item related to MGD was tearing sensation. Pearson’s correlation analysis revealed that tearing sensation was associated with tear meniscus height (TMH), noninvasive tear-film breakup time, fluorescein staining score, meiboscore, meibum grade, and Schirmer value. Subjects with MGD experienced significantly more tearing and had a larger TMH than did those without MGD (p = 0.0334). Tearing sensation may thus be a characteristic symptom of MGD. Physicians should suspect MGD who complain of tearing sensation.

Abstract
PURPOSE Carriers of functionally deficient mutations in the CYP39A1 gene have been recently reported to have a 2-fold increased risk of exfoliation syndrome (XFS). The aim of this study was to evaluate the risk of blindness and related clinical phenotypes of XFS patients carrying the loss-of-function CYP39A1 G204E mutation in comparison to XFS patients without any CYP39A1 mutation. DESIGN Retrospective case study PARTICIPANTS: 35 patients diagnosed with XFS carrying the CYP39A1 G204E mutation and 150 XFS patients without any CYP39A1 mutation, who were randomly selected from the Japanese XFS cohort. METHODS Two-sided Fisher's Exact Test with an α-level <0.05 was used to estimate the significance of the calculated Odds Ratio (OR) for all categorical measures. Comparisons between groups of subjects were performed using linear mixed effect models with group as random effect and taking possible dependence between eyes within a subject into account. MAIN OUTCOME MEASURES Primary analysis compared the incidence of blindness (defined as visual acuity [VA]<0.05 decimal), prevalence of exfoliation glaucoma (XFG), history of glaucoma surgery, and indices of glaucoma severity such as visual field mean deviation (MD), intraocular pressure (IOP) and vertical cup-disc ratio (CDR), between CYP39A1 G204E carriers and those without any CYP39A1 mutation. RESULTS The overall risk for blindness was significantly higher in XFS patients carrying the CYP39A1 G204E variant (10/35 [28.6%]) compared to XFS patients without any CYP39A1 mutations (8/150 [5.3%]; OR7.1 [95%CI:2.7-20.2]; p<0.001). A higher proportion of XFS patients with the CYP39A1 G204E mutation (23/35 [65.7%]) had evidence of XFG in at least one eye compared to the comparison group (41/150 [27.3%]; OR5.1 [95%CI:2.4-11.4]; p<0.0001). Significantly higher peak IOP, larger vertical CDR and worse visual field MD were also found in CYP39A1 G204E variant carriers (p<0.001). Additionally, patients with the CYP39A1 G204E mutation (18/35 [51.4%]) required more laser or glaucoma surgical interventions compared to those without any CYP39A1 mutation (32/150 [21.3%], p<0.001). CONCLUSIONS Patients with XFS carrying the CYP39A1 G204E mutation had significantly increased risk of blindness, higher occurrence of XFG and more severe glaucoma compared to patients with XFS without any CYP39A1 mutation.

Abstract
IMPORTANCE Exfoliation syndrome is a systemic disorder characterized by progressive accumulation of abnormal fibrillar protein aggregates manifesting clinically in the anterior chamber of the eye. This disorder is the most commonly known cause of glaucoma and a major cause of irreversible blindness. OBJECTIVE To determine if exfoliation syndrome is associated with rare, protein-changing variants predicted to impair protein function. DESIGN, SETTING, AND PARTICIPANTS A 2-stage, case-control, whole-exome sequencing association study with a discovery cohort and 2 independently ascertained validation cohorts. Study participants from 14 countries were enrolled between February 1999 and December 2019. The date of last clinical follow-up was December 2019. Affected individuals had exfoliation material on anterior segment structures of at least 1 eye as visualized by slit lamp examination. Unaffected individuals had no signs of exfoliation syndrome. EXPOSURES Rare, coding-sequence genetic variants predicted to be damaging by bioinformatic algorithms trained to recognize alterations that impair protein function. MAIN OUTCOMES AND MEASURES The primary outcome was the presence of exfoliation syndrome. Exome-wide significance for detected variants was defined as P < 2.5 × 10-6. The secondary outcomes included biochemical enzymatic assays and gene expression analyses. RESULTS The discovery cohort included 4028 participants with exfoliation syndrome (median age, 78 years [interquartile range, 73-83 years]; 2377 [59.0%] women) and 5638 participants without exfoliation syndrome (median age, 72 years [interquartile range, 65-78 years]; 3159 [56.0%] women). In the discovery cohort, persons with exfoliation syndrome, compared with those without exfoliation syndrome, were significantly more likely to carry damaging CYP39A1 variants (1.3% vs 0.30%, respectively; odds ratio, 3.55 [95% CI, 2.07-6.10]; P = 6.1 × 10-7). This outcome was validated in 2 independent cohorts. The first validation cohort included 2337 individuals with exfoliation syndrome (median age, 74 years; 1132 women; n = 1934 with demographic data) and 2813 individuals without exfoliation syndrome (median age, 72 years; 1287 women; n = 2421 with demographic data). The second validation cohort included 1663 individuals with exfoliation syndrome (median age, 75 years; 587 women; n = 1064 with demographic data) and 3962 individuals without exfoliation syndrome (median age, 74 years; 951 women; n = 1555 with demographic data). Of the individuals from both validation cohorts, 5.2% with exfoliation syndrome carried CYP39A1 damaging alleles vs 3.1% without exfoliation syndrome (odds ratio, 1.82 [95% CI, 1.47-2.26]; P < .001). Biochemical assays classified 34 of 42 damaging CYP39A1 alleles as functionally deficient (median reduction in enzymatic activity compared with wild-type CYP39A1, 94.4% [interquartile range, 78.7%-98.2%] for the 34 deficient variants). CYP39A1 transcript expression was 47% lower (95% CI, 30%-64% lower; P < .001) in ciliary body tissues from individuals with exfoliation syndrome compared with individuals without exfoliation syndrome. CONCLUSIONS AND RELEVANCE In this whole-exome sequencing case-control study, presence of exfoliation syndrome was significantly associated with carriage of functionally deficient CYP39A1 sequence variants. Further research is needed to understand the clinical implications of these findings.

Abstract
Abstract
Background
Pulmonary function is known to decrease with age and reduced pulmonary function has been reported to be associated with all-cause mortality and cardiovascular death. The association between pulmonary impairment and atherosclerosis was reported previously but has not been investigated sufficiently in the general population.
Purpose
We hypothesized that arterial stiffness could reflect increase of cardiac load and reduced pulmonary function. The present study aimed to investigate whether increased cardiac load and reduced pulmonary function could affect arterial stiffness in the general population.
Methods
Subjects undergoing their health check-up were enrolled. Plasma B-type natriuretic peptide (BNP) levels and serum high-sensitivity cardiac troponin I (hs-cTnI) levels were measured to evaluate cardiac load and myocardial damage. Radial augmentation index (rAI) was measured to investigate arterial stiffness using HEM-9000AI device. Subjects with an ST-T segment abnormality on the electrocardiogram, renal insufficiency, cancer, active inflammatory disease, or a history of cardiovascular events and pulmonary disease were excluded. Pulmonary function was assessed using spirometry by calculating forced vital capacity (FVC) as a percentage of predicted value (FVC%-predicted), forced expiratory volume in 1 second (FEV1) as a percentage of predicted value (FEV1%-predicted), and the ratio of FEV1 to FVC (FEV1/FVC).
Results
A total of 1100 subjects aged 57 years were enrolled and their median values of BNP and hs-cTnI were 15.5 and 2.3 pg/ml. The levels of rAI were significantly associated with the levels of BNP after adjustment for possible confounders in multivariate regression analysis, but were not with the levels of hs-TnI. While the parameters of pulmonary function were inversely associated with the levels of rAI and hs-cTnI after adjustment for possible confounders in the multivariate regression analysis, but not with the levels of BNP. The other multivariate regression analyses where BNP, hs-cTnI, parameters of pulmonary function, and the other possible factors were simultaneously included as independent variables revealed that the BNP levels and the FVC%-predicted or FEV1%-predicted, besides age, gender, smoking status, body mass index, blood pressure, heart rate, creatinine, fasting plasma glucose, and triglyceride, were significantly associated with the levels of rAI.
Conclusions
The significant associations of rAI with BNP and pulmonary function were revealed in the general population. These findings support that arterial stiffness could reflect increased cardiac load and reduced pulmonary function, in apparently healthy individuals.

Abstract
Aqueous-deficient dry eye (ADDE) and meibomian gland dysfunction (MGD) can be refractory to therapy. Intense pulsed light (IPL) was recently introduced as an effective treatment for MGD. We here evaluated the efficacy of IPL combined with MG expression (MGX) compared with MGX alone (n = 23 and 20, respectively) for patients with refractory ADDE with mild MGD at three sites. Symptom score, visual acuity (VA), noninvasive breakup time (NIBUT) and lipid layer thickness (LLT) of the tear film, lid margin abnormalities, fluorescein BUT (FBUT), fluorescein staining, tear meniscus height (TMH), meibum grade, meiboscore, and Schirmer's test value were assessed at baseline and 1 and 3 months after treatment. LLT, plugging, vascularity, FBUT and NIBUT were improved only in the IPL-MGX group at three months compared with baseline. All parameters with the exception of VA, meiboscore, TMH, Schirmer's test value were also improved in the IPL-MGX group compared with the control group at three months, as was VA in patients with central corneal epitheliopathy. Although IPL-MGX does not affect aqueous layer, the induced improvement in quality and quantity of the lipid layer may increase tear film stability and ameliorate symptoms not only for evaporative dry eye but for ADDE.

Abstract
Aims
Vascular inflammation via T-cell-mediated immune responses has been shown to be critically involved in the pathogenesis of abdominal aortic aneurysm (AAA). T-cell coinhibitory molecule cytotoxic T-lymphocyte–associated antigen-4 (CTLA-4) is known to act as a potent negative regulator of immune responses. However, the role of this molecule in the development of AAA remains completely unknown. In the present study, we determined the effects of CTLA-4 overexpression on experimental AAA.
Methods and results
We continuously infused 12-week-old CTLA-4 transgenic (CTLA-4-Tg)/apolipoprotein E–deficient (Apoe−/−) mice (n=35) or control Apoe−/− mice (n=40) fed a high-cholesterol diet with angiotensin II by implanting osmotic mini-pumps and evaluated the development of AAA. Ninety percent of angiotensin II-infused mice developed AAA, with 50% mortality because of aneurysm rupture. Overexpression of CTLA-4 significantly reduced the incidence (66%), mortality (26%), and diameter (18%) of AAA (incidence: P=0.0104; mortality: P=0.031; diameter: P=0.011). These protective effects were associated with a decreased number of effector CD4+ T cells and the downregulated expression of costimulatory molecules CD80 and CD86, ligands for CTLA-4, on CD11c+ dendritic cells in lymphoid tissues. In addition, by performing in situ zymography of the abdominal aortic aneurysm lesions, we observed a trend toward a decrease in MMP activity in the aneurysmal lesion following overexpression of CTLA-4. Finally, CTLA-4-Tg/Apoe−/− mice had reduced macrophage and CD4+ T cell accumulation and MMP activity in the aneurysmal lesion, leading to attenuated aortic inflammation, preserved vessel integrity, and decreased susceptibility to AAA and aortic rupture.
Conclusion
Our findings suggest that CTLA-4 protects against AAA by suppressing immunoinflammatory responses and could be an attractive therapeutic target for AAA.

Abstract
Objective We performed a pilot trial to evaluate the 24-month safety and efficacy of 360-degree suture trabeculotomy ab interno with phacoemulsification used to treat mild to moderate open-angle glaucoma coexisting with cataract. Methods and analysis We randomly assigned 18 eyes with open-angle glaucoma and coexisting cataract to undergo 360-degree suture trabeculotomy ab interno with phacoemulsification (combined) or phacoemulsification alone (control) (1:1 ratio) and followed up patients for 24 months. Main outcome measures were mean postoperative intraocular pressure (IOP) and success probabilities based on Kaplan-Meier life table analyses. Surgical success was defined as follows: criterion A: IOP value ≥6 mm Hg and ≤15 mm Hg, with ≥20 % reduction without medication; criterion B: IOP value ≥6 mm Hg and ≤12 mm Hg, with ≥30% reduction without medication. Secondary outcome measures included the number of medications, complications and best-corrected visual acuity. Results Mean IOP values (number of medications), which were 18.4 mm Hg (0.9) and 17.1 mm Hg (1.3) at baseline, showed significant reductions to 11.8 mm Hg (1.0) and 14.6 mm Hg (1.5) at 24 months postoperatively in the combined and control groups, respectively (p=0.0003 and 0.0192, respectively). Success rates for criterion A in the combined and control groups were 77.8% and 11.1%, respectively (p=0.0110) and those for criterion B in the combined and control groups were 46.7% and 0%, respectively (p=0.0036). Both groups had a similar overall occurrence of postoperative complications. Conclusion Using 360-degree suture trabeculotomy ab interno with phacoemulsification appeared to be a more beneficial option for mild to moderate open-angle glaucoma with coexisting cataract than phacoemulsification alone. Trial registration number UMIN000021170, date of registration: 2016/03/01.

Abstract
Purpose The purpose of this study was to evaluate the efficacy of 360-degree suture trabeculotomy (360S-LOT) ab interno for treating open-angle glaucoma (OAG). Risk factors of surgical failure were examined. Patients and methods 360S-LOT ab interno alone was performed for patients with uncontrolled OAG, and combined 360S-LOT ab interno/phacoemulsification was performed for patients with controlled OAG with a visually significant cataract between March 2014 and September 2015 at a single center. The patients were prospectively followed for 2 years. The main outcome measures included 2-year intraocular pressure (IOP), number of anti-glaucoma medications used, postoperative complications, and predictive factors of surgical failure. Kaplan-Meier analysis was performed, with surgical success (with or without medication use) defined as postoperative IOP ≤15 mmHg and IOP reduction ≥20% (criterion A) or IOP ≤12 mmHg and IOP reduction ≥30% (criterion B). Predictive factors were evaluated using Cox proportional hazard ratios. Results A total of 64 eyes of 64 patients were included, and 50 (78%) eyes of 64 eyes underwent a phacoemulsification combination procedure. Surgery significantly reduced IOP from 18.4 ± 2.9 mmHg before surgery to 13.4 ± 3.0 mmHg after surgery (P < 0.001). Patients used an average of 1.8 ± 1.5 medications before surgery and 1.3 ± 1.5 medications after surgery (P = 0.101). No serious postoperative complications were observed. The probability of surgical success was 49.2% and 16.0% using criteria A and B, respectively. No risk factors of surgical failure were identified. Conclusion The 360S-LOT ab interno procedure is a favorable option for treating eyes with mild or moderate OAG.

Abstract
Although the occurrence of cellulitis in lymphedema (LE) is believed to be an infection-related event, many findings in its clinical course seem to suggest that it is unlikely to be an infection. Therefore, we tried to clarify the specific features of cellulitis in LE. In-hospital courses of cellulitis obtained from medical charts were reviewed in the patients with leg LE (LE; 24 patients, 72admissions), chronic venous insufficiency (CVI; 28 patients, 29 admissions), and leg cellulitis secondary to wound infection without underlying disease (N; 42 patients, 42 admissions). The patients with LE complained of less local pain (peak numerical scale; LE: 1.4 ± 1.7, CVI: 4.1 ± 2.5, N: 3.2 ±2.0, p < 0.0001), showed an abnormally higher peak procalcitonin level (LE: 33.8 ± 34.8 (N = 7), CVI: 2.9 ± 5.8 (N = 8), N: 0.4 ± 0.6(N = 10), p < 0.05), and required fewer antibiotics (LE: 1.1 ± 0.3, CVI: 1.8 ± 0.9, N: 1.5 ± 0.9, p < 0.0001). These findings suggested that the occurrence of cellulitis in LE seems unlikely to be an infection-related type of cellulitis similar to that found in CVI.

Abstract
The circadian clock is synchronized by the day-night cycle to allow plants to anticipate daily environmental changes and to recognize annual changes in day length enabling seasonal flowering. This clock system has been extensively studied in Arabidopsis thaliana and was found to be reset by the dark to light transition at dawn. By contrast, studies on photoperiodic flowering of Pharbitis nil revealed the presence of a clock system reset by the transition from light to dark at dusk to measure the duration of the night. However, a Pharbitis photosynthetic gene was also shown to be insensitive to this dusk transition and to be set by dawn. Thus Pharbitis appeared to have two clock systems, one set by dusk that controls photoperiodic flowering and a second controlling photosynthetic gene expression similar to that of Arabidopsis. Here, we show that circadian mRNA expression of Pharbitis homologs of a series of Arabidopsis clock or clock-controlled genes are insensitive to the dusk transition. These data further define the presence in Pharbitis of a clock system that is analogous to the Arabidopsis system, which co-exists and functions with the dusk-set system dedicated to the control of photoperiodic flowering.

Abstract
Purpose To evaluate the efficacy and safety of 0.05% epinastine and 0.1% olopatadine eye drop preparations as seasonal and preseasonal treatments in patients with seasonal allergic conjunctivitis (SAC). Subjects and methods This was a prospective, randomized, case-control study involving two institutions. The subjects were patients diagnosed with SAC at two institutions between February and March in 2014. To examine the clinical effects of seasonal treatment, 0.05% epinastine and 0.1% olopatadine were administered, and their effects were investigated every 2 weeks (Stage 1). To evaluate the clinical effects of preseasonal therapy, in January 2015, the same eye drop preparations as adopted in Stage 1 were administered to patients who had participated in Stage 1 and provided consent to participate in this study, and their effects were investigated every month (Stage 2). Results In Stage 1, the 0.05% epinastine group consisted of 43 patients, and the 0.1% olopatadine group consisted of 42 patients. There were significant improvements in the total symptom and objective finding scores at each time point after administration in comparison with those before its baseline, but there were no significant differences between the two groups. In Stage 2, the 0.05% epinastine group consisted of 15 patients, and the 0.1% olopatadine group consisted of 14 patients. The rate of change in the total symptom score in comparison with that at the baseline of preseasonal treatment was significantly higher in the 0.1% olopatadine group 1 month after the start of treatment, suggesting symptom deterioration (P=0.025). There was no significant difference in the rate of change in the total objective finding score between the two groups. Conclusion Seasonal treatment with 0.05% epinastine or 0.1% olopatadine was equally effective for patients with allergic conjunctivitis. However, for preseasonal therapy, 0.05% epinastine was more effective than 0.1% olopatadine.

Abstract
Exfoliation syndrome (XFS) is the most common known risk factor for secondary glaucoma and a major cause of blindness worldwide. Variants in two genes, LOXL1 and CACNA1A, have previously been associated with XFS. To further elucidate the genetic basis of XFS, we collected a global sample of XFS cases to refine the association at LOXL1, which previously showed inconsistent results across populations, and to identify new variants associated with XFS. We identified a rare protective allele at LOXL1 (p.Phe407, odds ratio (OR) = 25, P = 2.9 × 10-14) through deep resequencing of XFS cases and controls from nine countries. A genome-wide association study (GWAS) of XFS cases and controls from 24 countries followed by replication in 18 countries identified seven genome-wide significant loci (P < 5 × 10-8). We identified association signals at 13q12 (POMP), 11q23.3 (TMEM136), 6p21 (AGPAT1), 3p24 (RBMS3) and 5q23 (near SEMA6A). These findings provide biological insights into the pathology of XFS and highlight a potential role for naturally occurring rare LOXL1 variants in disease biology.

Abstract
Although lysyl oxidase-like 1 (LOXL1) is known as the principal genetic risk factor for pseudoexfoliation (PEX) syndrome, a major cause of glaucoma and cardiovascular complications, no functional variants have been identified to date. Here, we conduct a genome-wide association scan on 771 German PEX patients and 1,350 controls, followed by independent testing of associated variants in Italian and Japanese data sets. We focus on a 3.5-kb four-component polymorphic locus positioned spanning introns 1 and 2 of LOXL1 with enhancer-like chromatin features. We find that the rs11638944:C>G transversion exerts a cis-acting effect on the expression levels of LOXL1, mediated by differential binding of the transcription factor RXRα (retinoid X receptor alpha) and by modulating alternative splicing of LOXL1, eventually leading to reduced levels of LOXL1 mRNA in cells and tissues of risk allele carriers. These findings uncover a functional mechanism by which common noncoding variants influence LOXL1 expression. LOXL1 is a genetic risk factor for pseudoexfoliation syndrome of the eye but a causal variant has not been identified. Here, Pasutto et al., find intronic LOXL1 risk variants influence transcription factor binding and alternative splicing of LOXL1 in affected tissues reducing levels of LOXL1 mRNA.

Abstract
A major goal with this research was to develop a low-cost and highly sensitive immunoassay detection system by using alternating current (AC) magnetic susceptibility. We fabricated an improved prototype of our previously developed immunoassay detection system and evaluated its performance. The prototype continuously moved sample containers by using a magnetically shielded brushless motor, which passes between two anisotropic magneto resistance (AMR) sensors. These sensors detected the magnetic signal in the direction where each sample container passed them. We used the differential signal obtained from each AMR sensor's output to improve the signal-to-noise ratio (SNR) of the magnetic signal measurement. Biotin-conjugated polymer beads with avidin-coated magnetic particles were prepared to examine the calibration curve, which represents the relation between AC magnetic susceptibility change and polymer-bead concentration. For the calibration curve measurement, we, respectively, measured the magnetic signal caused by the magnetic particles by using each AMR sensor installed near the upper or lower part in the lateral position of the passing sample containers. As a result, the SNR of the prototype was 4.5 times better than that of our previous system. Moreover, the data obtained from each AMR sensor installed near the upper part in the lateral position of the passing sample containers exhibited an accurate calibration curve that represented good correlation between AC magnetic susceptibility change and polymer-bead concentration. The conclusion drawn from these findings is that our improved immunoassay detection system will enable a low-cost and highly sensitive immunoassay.

Abstract
Exfoliation syndrome (XFS) is a common, age-related, systemic fibrillinopathy. It greatly increases risk of exfoliation glaucoma (XFG), a major worldwide cause of irreversible blindness. Coding variants in the lysyl oxidase-like 1 (LOXL1) gene are strongly associated with XFS in all studied populations, but a functional role for these variants has not been established. To identify additional candidate functional variants, we sequenced the entire LOXL1 genomic locus (∼40 kb) in 50 indigenous, black South African XFS cases and 50 matched controls. The variants with the strongest evidence of association were located in a well-defined 7-kb region bounded by the 3'-end of exon 1 and the adjacent region of intron 1 of LOXL1. We replicated this finding in US Caucasian (91 cases/1031 controls), German (771 cases/1365 controls) and Japanese (1484 cases/1188 controls) populations. The region of peak association lies upstream of LOXL1-AS1, a long non-coding RNA (lncRNA) encoded on the opposite strand of LOXL1. We show that this region contains a promoter and, importantly, that the strongly associated XFS risk alleles in the South African population are functional variants that significantly modulate the activity of this promoter. LOXL1-AS1 expression is also significantly altered in response to oxidative stress in human lens epithelial cells and in response to cyclic mechanical stress in human Schlemm's canal endothelial cells. Taken together, these findings support a functional role for the LOXL1-AS1 lncRNA in cellular stress response and suggest that dysregulation of its expression by genetic risk variants plays a key role in XFS pathogenesis.

Abstract
Background The purpose of this study was to determine outcomes when using Trabectome surgery and to evaluate factors associated with its effects in primary open-angle glaucoma (POAG) and exfoliation glaucoma (EXG). Methods This was a prospective, non-randomized, observational, comparative cohort study in which Trabectome surgery was used alone in patients with POAG or EXG. Trabectome surgery was considered to have failed when at least one of the following three criteria was fulfilled: intraocular pressure (IOP) ≥21 mmHg and a <20% reduction below the baseline IOP on two consecutive follow-up visits 3 months or more after surgery; need for additional glaucoma surgery; and an increase in number of medications compared with baseline. Results The subjects were 32 males (34 eyes) and 46 females (48 eyes). POAG was observed in 43 eyes and EXG in 39 eyes. IOP after Trabectome surgery decreased significantly from 22.3±6.8 mmHg at baseline to 14.0±3.9 mmHg (23.0% reduction) at month 24 in all cases (P<0.0000). The success rate at 2 years was 51.2% for all cases (POAG, 50.9%; EXG, 49.2%). There was no significant difference in success rate between POAG and EXG (P=0.91). Preoperative IOP (P=0.033) and number of medications (P=0.041) were significant factors for surgical success/failure in multivariate logistic regression. No serious complications were observed. Conclusion Trabectome surgery achieved favorable IOP control and was equally effective in patients with POAG and those with EXG. Its effects were influenced by preoperative IOP and number of preoperative medications.

Abstract
Purpose To determine the prevalence of plateau iris in Japanese patients with primary angle closure (PAC) and primary angle closure glaucoma (PACG) and analyze the biometric parameters in patients with plateau iris using ultrasound biomicroscopy (UBM). Methods In this cross-sectional observational study, subjects aged >50 years with PAC and PACG who had previously undergone a patent laser peripheral iridotomy underwent UBM in one eye. UBM images were qualitatively analyzed using standardized criteria. Plateau iris in a quadrant was defined by anteriorly directed ciliary body, absent ciliary sulcus, steep iris root from its point of insertion followed by a downward angulation, flat iris plane, and irido-angle contact. At least two quadrants had to fulfill these UBM criteria for an eye to be classified as having plateau iris. A-scan biometry was used to measure anterior segment parameters. Results Ninety-one subjects with PAC (58 subjects) or PACG (33 subjects) and 68 normal controls were recruited. The mean (standard deviation) ages of PAC and PACG patients and normal controls were 73.5 (6.2) and 72.6 (7.3), respectively. Based on UBM criteria, plateau iris was found in 16 eyes (17.6%) of 91 eyes. In these 16 eyes, quadrant-wise analysis showed ten eyes (62.5%) had plateau iris in two quadrants; four eyes (25%) had plateau iris in three quadrants; and two eyes (12.5%) had plateau iris in four quadrants. Anterior chamber depth, lens thickness, axial length, lens position, and relative lens position were not statistically significant between the group having plateau iris and that not having plateau iris, respectively. Conclusion Approximately 20% of Japanese subjects with PAC and PACG with a patent laser peripheral iridotomy were found to have plateau iris on UBM. No morphological difference was noted in the anterior segment of the eye between those with or without plateau iris.

Abstract
Primary open angle glaucoma (POAG), a major cause of blindness worldwide, is a complex disease with a significant genetic contribution. We performed Exome Array (Illumina) analysis on 3504 POAG cases and 9746 controls with replication of the most significant findings in 9173 POAG cases and 26 780 controls across 18 collections of Asian, African and European descent. Apart from confirming strong evidence of association at CDKN2B-AS1 (rs2157719 [G], odds ratio [OR] = 0.71, P = 2.81 × 10−33), we observed one SNP showing significant association to POAG (CDC7–TGFBR3 rs1192415, ORG-allele = 1.13, Pmeta = 1.60 × 10−8). This particular SNP has previously been shown to be strongly associated with optic disc area and vertical cup-to-disc ratio, which are regarded as glaucoma-related quantitative traits. Our study now extends this by directly implicating it in POAG disease pathogenesis.

Abstract
OBJECTIVES To understand the differences and similarities between immunocompetent and immunodeficient mice as ectopic transplantation animal models for bone tissue engineering. MATERIALS AND METHODS Osteogenic cells from mouse leg bones were cultured, seeded on β-TCP granules, and transplanted onto the backs of either immunocompetent or immunodeficient nude mice. At 1, 2, 4, and 8 weeks postoperatively, samples were harvested and evaluated by hematoxylin-eosin staining, tartrate-resistant acid phosphatase (TRAP) staining, and immunohistochemical staining and quantitative PCR. RESULTS In immunocompetent mice, inflammatory cell infiltration was evident at 1 week postoperatively and relatively higher expression of TNF-α and IL-4 was observed. In immunodeficient mice, new bone area and the number of TRAP-positive cells were larger at 4 weeks than in immunocompetent mice. The volume of new bone area in immunodeficient mice was reduced by 8 weeks. CONCLUSIONS Bone regeneration was feasible in immunocompetent mice. However, some differences were observed between immunocompetent and immunodeficient mice in the bone regeneration process possibly due to different cytokine expression, which should be considered when utilizing in vivo animal models.

Abstract
Exfoliation syndrome (XFS) is the most common recognizable cause of open-angle glaucoma worldwide. To better understand the etiology of XFS, we conducted a genome-wide association study (GWAS) of 1,484 cases and 1,188 controls from Japan and followed up the most significant findings in a further 6,901 cases and 20,727 controls from 17 countries across 6 continents. We discovered a genome-wide significant association between a new locus (CACNA1A rs4926244) and increased susceptibility to XFS (odds ratio (OR) = 1.16, P = 3.36 × 10(-11)). Although we also confirmed overwhelming association at the LOXL1 locus, the key SNP marker (LOXL1 rs4886776) demonstrated allelic reversal depending on the ancestry group (Japanese: OR(A allele) = 9.87, P = 2.13 × 10(-217); non-Japanese: OR(A allele) = 0.49, P = 2.35 × 10(-31)). Our findings represent the first genetic locus outside of LOXL1 surpassing genome-wide significance for XFS and provide insight into the biology and pathogenesis of the disease.

Abstract
PURPOSE To compare anterior segment parameters in Chinese and Japanese subjects with angle closure using anterior segment optical coherence tomography (ASOCT). METHODS One hundred and forty-two Japanese and one hundred and ninety-two Chinese subjects with primary angle closure (PAC) or primary angle-closure glaucoma (PACG) were recruited. All participants underwent A-scan biometry and ASOCT imaging (Visante, Carl Zeiss Meditec, Dublin, CA, USA). Customized software was used to measure ASOCT parameters in horizontal ASOCT scans. The parameters were compared, and multivariate analysis was performed to determine predictors of angle opening distance at 750 μm from the scleral spur (AOD750). RESULTS Ethnic difference evaluated by multiple linear regression adjusted for age, gender, spherical equivalent, pupil diameter, and axial length showed that Japanese angle-closure subjects had significantly shallower anterior chamber depth (ACD;β = -0.3, p < 0.001), smaller anterior chamber area (ACA; β = -0.21, p = 0.02) and volume (ACV; β = -0.19, p = 0.01), greater lens vault (LV, β = 0.3, p < 0.001), lens thickness (LT; β = 0.48, p < 0.001), greater iris area (IArea; β = 0.19, p = 0.01), and more curved iris (ICurv; β = 0.16, p = 0.04). The significant determinants of AOD750 were iris thickness (IT; β = -0.21, p = 0.04), ICurv (β = -0.17, p = 0.04), pupil diameter (PD; β = -0.34, p = 0.001) and ACV (β = 0.32, p < 0.001) in Japanese; and IT (β = -0.25, p = 0.001), ACV (β = 0.37, p < 0.001), PD (β = -0.26, p = 0.001), and LV (β = -0.18, p = 0.03) in Chinese. CONCLUSIONS Compared to Chinese, Japanese angle-closure eyes have smaller and more crowded anterior segment with thicker lenses. ACV, IT, and PD are important factors for angle width in both races. These results suggest possible ethnic differences in angle-closure mechanism(s).

Abstract
Age-related macular degeneration (AMD) is a major cause of blindness, but presents differently in Europeans and Asians. Here, we perform a genome-wide and exome-wide association study on 2,119 patients with exudative AMD and 5,691 controls, with independent replication in 4,226 patients and 10,289 controls, all of East Asian descent, as part of The Genetics of AMD in Asians (GAMA) Consortium. We find a strong association between CETP Asp442Gly (rs2303790), an East Asian-specific mutation, and increased risk of AMD (odds ratio (OR)=1.70, P=5.60 × 10−22). The AMD risk allele (442Gly), known to protect from coronary heart disease, increases HDL cholesterol levels by 0.17 mmol l−1 (P=5.82 × 10−21) in East Asians (n=7,102). We also identify three novel AMD loci: C6orf223 Ala231Ala (OR=0.78, P=6.19 × 10−18), SLC44A4 Asp47Val (OR=1.27, P=1.08 × 10−11) and FGD6 Gln257Arg (OR=0.87, P=2.85 × 10−8). Our findings suggest that some of the genetic loci conferring AMD susceptibility in East Asians are shared with Europeans, yet AMD in East Asians may also have a distinct genetic signature. Age-related macular degeneration (AMD) is a major cause of blindness worldwide. Here, the authors carry out a two-stage genome-wide association study for AMD and identify three new AMD risk loci, highlighting the shared and distinct genetic basis of the disease in East Asians and Europeans.

Abstract
BACKGROUND In this paper, we describe 360° suture trabeculotomy (360°LOT) ab interno and the short-term course in patients who underwent this procedure. METHODS We prospectively studied 12 patients (12 eyes) with open-angle glaucoma who underwent 360°LOT ab interno at the Sato Eye Clinic between February and July 2014. The surgical procedure involved making a 1.7 mm temporal corneal incision, exposing an approximately 15° opening in the inner wall of Schlemm's canal (nasal side) using a Trabectome with a gonioscope, and inserting a 5-0 nylon suture rounded at the tip into Schlemm's canal opened via the anterior chamber. The suture was then threaded around Schlemm's canal, and the tip of the suture that emerged on the other side was then advanced through the opening to make a circumferential incision. Intraocular pressure (IOP), number of anti-glaucoma medications used, complications, and the surgery completion rate were prospectively studied. RESULTS Mean IOP, which was 19.4 mmHg at baseline, showed a significant decrease at each of the monthly observation points, reaching 13.8 mmHg at 6 months after surgery (P=0.0004, paired t-test). The mean number of anti-glaucoma medications decreased from 3.2 at baseline to 1.1 at 6 months after surgery. IOP spikes ≥30 mmHg were seen in 25% of patients, but there were no other serious complications and the surgery completion rate was 92%. CONCLUSION The 360°LOT ab interno procedure preserves the conjunctiva and sclera, and has a high surgery completion rate when using the anterior chamber approach, and could therefore be an effective short-term treatment of open-angle glaucoma.

Abstract
BACKGROUND The purpose of this study was to investigate treatment outcomes in 360° suture trabeculotomy with deep sclerectomy combined with phacoemulsification and aspiration and intraocular lens implantation (360P-LOT + DS). METHODS Thirty-two eyes in 32 consecutive patients treated by 360P-LOT + DS for primary open angle glaucoma with coexisting cataracts at Sato Eye Clinic from March 2011 to April 2013 were retrospectively compared with 23 eyes in 23 consecutive patients treated by cataract surgery and 120° trabeculotomy with deep sclerectomy (120P-LOT + DS) at the same clinic from January 2010 to February 2011. The parameters investigated during the 15 months after surgery were the course of intraocular pressure, number of antiglaucoma medications, best-corrected visual acuity, and complications. RESULTS Both groups showed a significant decrease in intraocular pressure starting at one month after surgery when compared with values before surgery. At 3, 6, 9, and 15 months after surgery, the intraocular pressure was significantly lower and the survival rate was significantly higher in the 360P-LOT + DS group compared with the 120P-LOT + DS group. The number of antiglaucoma medications, best-corrected visual acuity value, and complications did not differ significantly between the groups. CONCLUSION Although the complications are similar to those seen in 120P-LOT + DS, treatment of primary open angle glaucoma and coexisting cataracts using 360P-LOT + DS may yield better outcomes.

Abstract
Purpose To investigate the relation between the quantitative iris parameters and iridotrabecular contact (ITC) in patients with primary angle-closure (PAC) and PAC glaucoma (PACG). Materials and methods PAC and PACG with laser peripheral iridotomy were recruited prospectively. Anterior-segment optical coherence tomography (ASOCT) was performed under light and dark conditions, and scans were taken along the vertical and horizontal axes. Iris thickness at 500 μm (IT500) and 750 μm (IT750) from the scleral spur, maximal iris thickness (MIT), and cross sections of the iris area (I-Area) were measured by using software. ITC was defined by the ASOCT as the contact between the peripheral iris and angle wall anterior to the scleral spur. The ITC+ and ITC− groups were defined as eyes that had ITC in two or more quadrants and in no or one quadrant, respectively. Results A total of 79 eyes of 60 patients (consisting of 48 PAC and 31 PACG) were recruited. The prevalence of superior, inferior, temporal, and nasal ITC was 44 eyes (55.7%), 48 eyes (60.8%), 18 eyes (22.8%), and 16 eyes (20.2%), respectively. These iris parameters of the inferior quadrant, which had the highest prevalence of all the quadrants, were used for the analysis. After adjusting for age, sex, pupil size, and central anterior chamber depth, mean values of IT500 and IT750 were significantly greater in the ITC+ group than the ITC− group (P<0.05). Multivariate-adjusted odds ratios of parameters for the ITC+ group compared with the ITC− group were: IT500, 1.9 (P=0.029); IT750, 2.0 (P=0.011), MIT, 1.4 (P=0.244), and I-Area, 0.97 (P=0.406), respectively, per 0.1-unit increase. Conclusion Peripheral iris thickness is associated with ITC in patients with angle closure.

Abstract
A hierarchial co-culture, in which rat hepatocytes and non-parenchymal liver cells (NPLCs) were separated by a collagen layer and which was designed to mimic the in vivo microenvironment, was carried out with the aim of developing a module for bio-artificial liver support. Compared with a monolayer co-culture and hepatocytes cultured alone in a monolayer, higher urea synthesis activity was maintained for 6 d in the hierarchical co-culture. When a rat hepatoma cell line H4-II-E-C3, which retains the induction of tyrosine aminotransferase (TAT), was co-cultured in a monolayer with NPLCs, dose-dependent stimulation of TAT induction was observed. In a hierarchical co-culture, NPLCs further stimulated TAT induction in H4-II-E-C3 cells. Since peritoneal macrophages could stimulate TAT induction in hepatocytes in both monolayer and hierarchical co-cultures, bone marrow cells, which can proliferate and differentiate into macrophages in vitro, were investigated as a possible substitute for NPLCs. Bone marrow cells isolated from rat femurs were cultivated in the presence of IL-3 and macrophage colony-stimulating factor (M-CSF), and co-cultured with hepatocytes. Urea synthesis and TAT induction of hepatocytes were stimulated in the co-culture. The co-culture of bone marrow and H4-II-E-C3 cells, both of which have proliferation ability in vitro, was also shown to be effective in stimulating liver functions. The hierarchical configuration, in which two cell types can communicate with the soluble factor(s) through a collagen layer, was found to be more effective than a monolayer in long-term co-culture.

Abstract
Purpose: We compared the intraocular pressure (IOP)-lowering effect of tafluprost 0.0015% once daily with travoprost 0.004% once daily in Japanese patients with normal-tension glaucoma (NTG). Methods: One hundred sixteen patients with NTG were randomized to use tafluprost 0.0015% or travoprost 0.004% once daily for 12 weeks, followed by a washout period of 4 weeks between switching medications. IOP was measured at baseline and 4, 8, and 12 weeks of each treatment period. Results: Ninety patients completed both treatment periods and had IOP data available for evaluation. In both groups, a significant decrease in IOP was observed for all measurement points compared with baseline values (P < 0.0001). There was no significant difference in IOP at each time point between the two groups. Both drugs were effective (defined as more than 10% IOP reduction) in 39 (43%) of 90 patients; only tafluprost was effective in 26 (29%) patients, and only travoprost was effective in 17 (19%) patients. Eight (9%) patients were nonresponders to both drugs. Conclusions: Tafluprost and travoprost were equally effective in lowering IOP in patients with normal-tension glaucoma. However, patients with normal-tension glaucoma may vary in response to each medication.

Abstract
A high-performance liquid chromatographic assay for monitoring the antifungal drug fluconazole in human serum was developed using a C18 reversed-phase column with isocratic elution. The method involved sample clean-up by solid-phase column extraction, and subsequent analysis required only 14 min per sample for separation and quantitation. The assay was precise, with intra- and inter-assay relative standard deviations of < or = 1.5% and < or = 3.1%. The minimum detectable concentration of fluconazole was 0.3 nmol/ml. This assay has the advantage of minimizing the risk of interference from co-administered drugs to critically ill patients undergoing hemodiafiltration.

Abstract
Purpose To evaluate the intraocular pressure (IOP)-lowering effect of adding dorzolamide 1.0%/timolol 0.5% fixed combination (DTFC) to prostaglandin analogs (PGAs) as monotherapy in patients with normal tension glaucoma. Methods A prospective, clinical, case-controlled study of patients with normal tension glaucoma. Patients had been on a once-daily night dose of prostaglandins (PGs) as monotherapy and then received DTFC added to PGs for 8 weeks. The IOP was measured at 9 am, week 0 (baseline), week 4, and week 8. Results The baseline IOP of 40 patients who had previously been treated by prostaglandin monotherapy was 15.6 ± 2.0 mmHg at baseline. The IOPs at 4 and 8 weeks after adding DTFC to PGs were 13.5 ± 2.1 mmHg and 13.7 ± 2.2 mmHg, respectively. Significant decrease of the IOP was observed at each time point of measurement as compared with the baseline IOP before adding DTFC (P = 0.01). The percent IOP reduction from the baseline IOP at week 4 and week 8 was 13.5% ± 12.3% and 11.7% ± 13.1%, respectively. The percentage of patients who achieved 10% or more IOP reduction from the baseline IOP at week 8 was 62.5%. The baseline IOP was significantly correlated with the percent IOP reduction at week 8 (P = 0.03, r = 0.34). Conclusion DTFC therapy added to PGAs as glaucoma monotherapy is effective in patients with normal tension glaucoma.

Abstract
Tularemia is a zoonotic disease caused by Francisella tularensis. The distribution of the pathogen in Japan has not been studied well. In this study, seroprevalence of tularemia among wild black bears and hares in Japan was determined. Blood samples collected from 431 Japanese black bears (Ursus thibetanus japonicus) and 293 Japanese hares (Lepus brachurus) between 1998 and 2009 were examined for antibodies against F. tularensis by micro-agglutination test (MA) or enzyme-linked immunosorbent assay. By subsequent confirmatory tests using western blot (WB) and indirect immunofluorescence assay (IFA), eight sera from Japanese black bears were definitely shown to be seropositive. All of these eight bears were residents of the northeastern part of main-island of Japan, where human tularemia had been reported. On the other hand, no seropositive Japanese hares were found. These results suggest that Japanese black bears can serve as sentinel for tularemia surveillance and may help understand the distribution of F. tularensis throughout the country. This is the first report on detection of antibody to F. tularensis in black bears of Japan.

Abstract
The oxidation state of Mn in cubic SrMnO(3) and orthorhombic SrMnO(2.5) was investigated by electron energy loss (EEL) spectroscopy. Change in the oxidation state of Mn produced some spectral changes in the O-K edge as well as in the Mn-L(2,3) edge EEL spectra. This study demonstrated that the oxidation state of Mn and the amount of oxygen vacancies in cubic SrMnO(3) and orthorhombic SrMnO(2.5) could be quantified by analyzing the features of the O-K edge spectrum and the Mn L(3)∕L(2) ratio in the Mn-L(2,3) edge spectrum. Our quantitative analysis showed that the spectral changes in the Mn-L(2,3) edge were mainly caused by the oxidation state of Mn, whereas those in the O-K edge could be sensitive to both the oxidation state of Mn and to lattice distortions.

Abstract
Determining the atomic structure of internal interfaces in materials and devices is critical to understanding their functional properties. Interfacial doping is one promising technique for controlling interfacial properties at the atomic scale, but it is still a major challenge to directly characterize individual dopant atoms within buried crystalline interfaces. Here, we demonstrate atomic-scale plan-view observation of a buried crystalline interface (an yttrium-doped alumina high-angle grain boundary) using aberration-corrected Z-contrast scanning transmission electron microscopy. The focused electron beam transmitted through the off-axis crystals clearly highlights the individual yttrium atoms located on the monoatomic layer interface plane. Not only is their unique two-dimensional ordered positioning directly revealed with atomic precision, but local disordering at the single-atom level, which has never been detected by the conventional approaches, is also uncovered. The ability to directly probe individual atoms within buried interface structures adds new dimensions to the atomic-scale characterization of internal interfaces and other defect structures in many advanced materials and devices.

Abstract
Retrospective study examined the surgical effects of lowering intraocular pressure of trabeculotomy combined with phacoemulsification and implantation of an intraocular lens. Included in the retrospective study were 96 eyes of 64 patients with primary open-angle glaucoma. Preoperative mean IOP was 25.6 mmHg. At final examination, the IOP was well-controlled at 21 mmHg or lower without medications in 32 of 96 eyes. In another 62 eyes, the IOP was well-controlled with antiglaucoma medications. The postoperative IOPs were in the high teens after surgery. The life table analysis using Kaplan-Meier methods showed that the success probability after phacoemulsification and implantation of intraocular lens, combined with trabeculotomy (PIT)-I and PIT-II, were 93.9% and 82.6% at 4 years, respectively. Postoperative visual acuity improved by more than two lines in 79 of the 96 eyes. In no case was the visual acuity decreased by more than two lines. Deterioration of the visual field was found in 4 eyes. There were no complications such as shallow anterior chamber, choroidal detachment, malignant glaucoma, hypotonic maculopathy, and endophthalmitis. This triple procedure should be performed in the early stages of glaucoma. Trabeculotomy is thought to relieve the resistance to aqueous outflow by mechanical cleavage of the trabecular meshwork and the inner layer of Schlemm's canal. This technique leads to aqueous outflow the from the opening of the internal trabecular meshwork to the collector channel. For this reason trabeculotomy was developed by a number of surgeons. Recently, however, trabeculotomy has not been selected for those patients with advanced stages of primary open-angle glaucoma because of the disadvantages such as transient intraocular pressure (IOP) elevation several days after surgery and somewhat higher levels (18 mmHg) of postoperative intraocular pressure (Fig. 1). To avoid the IOP spike (transient IOP elevation) after trabeculotomy, we reported previously that the new technique of trabeculotomy combined with outer sclerectomy was a useful surgical option. The results of our previous study indicated that the postoprative intraocular pressure levels after combined trabeculotomy and outer sclerectomy were significantly lower than that of trabeculotomy alone. On the other hand, trabeculotomy with mitomycin C is currently the standard filtration procedure for glaucoma. This technique, however causes severe postoperative complication such as hypotonic maculopathy, bleb leakage and late bleb infection. The major advantages of trabeculotomy preclude these severe complications resulting from creating progressive filtration of aqueous humor from the anterior chamber to the subconjunctival space. The recent advance of small-incision phacoemulsification procedure prompted phacoemulsification and implantation of intraocular lens and trabeculotomy. The theoretical advantages of smaller scleral, conjunctival incision, reduced stimuli to wound healing, and inflammation, could improve long-term IOP control in patients with glaucoma. Therefore several reports have been published on the surgical outcomes of combined trabeculotomy and modern phacoemulsification. These reports suggested that the combined trabeculotomy and a small-incision with intraocular lens implantation is effective in controlling IOP in patients with glaucoma.

Abstract
We have devised a new glaucoma surgery combining deep sclerectomy with nonpenetrating trabeculectomy (NPT); we call this surgery advanced NPT. We evaluated intraocular pressure (IOP) control, postoperative complication and visual acuity after combined advanced NPT and phacoemulsification and intraocular lens implantation (combined surgery), and advanced NPT alone. The mean preoperative IOP for the trabeculectomy only group was 22.4 +/- 6.3 mmHg(bleb+), 23.0 +/- 4.9 mmHg(bleb-), and that of the combined surgery group was 18.1 +/- 4.5 mmHg(bleb+), 18.5 +/- 2.6 mmHg(bleb-). Mean postoperative IOP for the two groups were 13.0 +/- 2.3 mmHg(bleb+), 15.0 +/- 1.5 mmHg(bleb-) and 12.9 +/- 2.7 mmHg(bleb+), 13.3 +/- 2.4 mmHg(bleb-), respectively. After 15 months, the success probability for postoperative IOP control were 63%(bleb+), 23%(bleb-) in the advanced NPT only group (<or=12 mmHg), and 60% in the advanced NPT only group, 70% in the combined surgery group (<or=14 mmHg) (Kaplan-Meier survival rate). In early complication, there were significantly fewer cases of shallow anterior chamber, hypertension, hypotension and anterior chamber inflamation in both groups than that of trabeculectomy. Nd:YAG goniopuncture was performed for purposes of better IOP control; preferred performance being within a month after surgery. Regarding visual acuity after either advanced NPT alone or combined surgery, an earlier recovery can be expected than with trabeculectomy. Advanced NPT and combined procedure is a reliable technique for glaucoma and cataract surgery.

Abstract
It has recently become popular to use mitomycin C (MMC) with trabeculectomy. MMC helps to maintain effective filtration and long-term intraocular pressure (IOP) control, while the use of laser suture lysis has improved the safety of this procedure. We evaluated the outcome of trabeculectomy alone and of trabeculectomy plus phacoemulsification (PEA) and intraocular lens (IOL) implantation, each supplemented with MMC. The mean preoperative IOP for the trabeculectomy alone group was 22.4 +/- 3.2 mmHg(bleb+), 25.3 +/- 2.6 mmHg(bleb-), and that of the combined surgery group was 22.4 +/- 2.8 mmHg(bleb+), 21.0 +/- 3.5 mmHg(bleb-). Mean postoperative IOP for the two groups were 13.3 +/- 2.7 mmHg(bleb+), 17.1 +/- 4.4 mmHg(bleb-) and 11.9 +/- 2.7 mmHg(bleb+), 16.4 +/- 3.4 mmHg(bleb-), respectively. After 4.5 years, the success probability for postoperative IOP control was 38%(bleb+), 3%(bleb-) in the trabeculectomy alone group and 53%(bleb+), 10%(bleb-) in the combined surgery group (<or=12 mmHg) and 65%(bleb+), 3%(bleb-) and 75%(bleb+), 10%(bleb-) (<or=14 mmHg)(Kaplan-Meier survival rate). With early complications, the frequency of shallow anterior chamber and choroidal detachment were significantly fewer in the combined surgery group. The combined surgery of PEA, IOL implantation and trabeculectomy is an effective procedure that offers visual rehabilitation, fewer early complications and good IOP control in patients with advanced, medically uncontrolled glaucoma and cataract.

Abstract
Scanning transmission electron microscopy and density functional theory are used to characterize atomic structures of nanoscale heterointerfaces between gold nanoparticles and a TiO2 (110) surface. It is found that when the gold nanoparticle size is smaller than a few nanometers, gold atoms preferentially attach to specific sites on the TiO2 surface and thus form an epitaxial and coherent heterointerface. Conversely, as the gold size becomes larger, the gold-TiO2 interface loses lattice coherency in order to accommodate the large lattice mismatch between the two dissimilar crystals.

Abstract
Oxygen K-electron energy loss near edge structures (ELNES) of monoclinic, tetragonal, and cubic HfO(2) were calculated by the first-principles full-potential augmented plane wave plus local orbitals (APW+lo) method. By considering the relativistic effect as well as the core-hole effect in the calculation, the experimental oxygen K ELNES was successfully reproduced. The first, second, third, and fourth peaks originate from oxygen p components hybridized with Hf d-e(g), d-t(2g), s, and p components, respectively. It was found that the spectral differences among the polymorphs are mainly caused by the local structure of the Hf in the crystal.

Abstract
Tomato (Solanum lycopersicum L., Solanaceae) is an excellent model plant for genomic research of solanaceous plants, as well as for studying the development, ripening, and metabolism of fruit. In 2003, the International Solanaceae Project (SOL, www.sgn.cornell.edu ) was initiated by members from more than 30 countries, and the tomato genome-sequencing project is currently underway. Genome sequence of tomato obtained by this project will provide a firm foundation for forthcoming genomic studies such as the comparative analysis of genes conserved among the Solanaceae species and the elucidation of the functions of unknown tomato genes. To exploit the wealth of the genome sequence information, there is an urgent need for novel resources and analytical tools for tomato functional genomics. Here, we present an overview of the development of genetic and genomic resources of tomato in the last decade, with a special focus on the activities of Japan SOL and the National Bio-Resource Project in the development of functional genomic resources of a model cultivar, Micro-Tom.

Abstract
PURPOSE The single nucleotide polymorphisms (SNPs) rs1048661, rs3825942, and rs2165241 within the LOXL1 gene were recently found to confer risk of pseudoexfoliation glaucoma (XFG) through pseudoexfoliation syndrome (XFS) in Caucasians. The purpose of this study was to test this association in Japanese subjects with XFS/XFG. METHODS Japanese subjects with clinically diagnosed XFS/XFG and normal control subjects were recruited. Genomic DNA was extracted and the three SNPs of the LOXL1 gene were genotyped by bidirectional sequencing. The association of individual SNPs with XFG/XFS was evaluated by using chi(2) and the Fisher exact test. RESULTS Two hundred nine Japanese patients (106 XFG and 103 XFS) and 172 control subjects were studied. Strong associations were observed for all three SNPs of LOXL1 for XFS (odds ratio [OR] = 13.56, P = 3.39 x 10(-28) for allele T of rs1048661; OR = 10.71, P = 1.49 x 10(-7) for allele G of rs3825942; and OR = 4.55, P = 5.33 x 10(-4) for allele C of rs2165241) and XFG (OR = 25.21, P = 1.44 x 10(-34) for allele T of rs1048661; OR = 11.02, P = 1.40 x 10(-7) for allele G of rs3825942; and OR = 11.89, P = 4.76 x 10(-6) for allele C of rs2165241). The risk-associated alleles of rs1048661 and rs2165241 differed between the Japanese and Caucasians, whereas allele G of rs3825942 was associated with disease in both populations. Conditional analysis indicated that rs3825942 was not independent but correlated highly with rs1048661. The at-risk haplotype T-G-C was present at an approximately two times higher rate (94.7% vs. 50.6%, P = 4.22 x 10(-43)) in cases than in control subjects and conferred a 2.9-fold (95% confidence interval [CI], 2.357-3.464) increased likelihood of XFS. CONCLUSIONS Polymorphisms in the LOXL1 gene confer risk to XFS/XFG in the Japanese, but there are different risk-associated alleles and haplotypes in the Japanese.
