Abstract
Patients with cleft lip and palate (CLP) encounter various problems, including disorders related to feeding, esthetics, and pronunciation. We compared two impression methods, conventional impression making and intraoral scanning, to study unilateral cleft lip and palate (UCLP). Patients with UCLP (n = 7) were selected, and palatal impressions were taken by two steps: (1) impressions were obtained using an addition silicone rubber impression material, and a plaster model was prepared and (2) optical impressions were obtained using a desktop three-dimensional (3D) scanner and stereolithography (STL). Data were generated by two impression system combinations through STL. The results were analyzed using the Kruskal-Wallis or Mann-Whitney U test. There were no significant differences in the dimensions of the models between both groups. The measured depth of the alveolar cleft defects was deeper in the plaster model group (STL) than in the intraoral scanner group (STL). Digital models may prevent the risk of aspiration and respiratory disorders by using impression materials for preoperative jaw treatment of newborns and infants. We compared the results of both impression methods in the same patient and found that a shift to the 3D printer model is a safe alternative for preoperative jaw correction, as evidenced from the amount of tissue displaced due to the pressure applied during impression taking. In the future, we would like to conduct clinical research with a larger sample size of CLP patients to further corroborate these findings.

Abstract
Background:Giant cell arteritis (GCA) is characterized by cranial symptoms and large-vessel lesions (LVL) in the aorta or its branches. We retrospectively analyzed the Japanese patients newly diagnosed as GCA between 2007 and 2014, and subsequently treated with glucocorticoid (GC). The imaging studies revealed that LVLs were observed in approximately half of the GCA patients, and the LVLs were significantly associated with the increased probability of poor treatment outcomes (1).Objectives:The objective of this study is to evaluate whether the distribution of LVLs of GCA was associated with poor treatment response.Methods:In a retrospective, multi-centric, nationwide registry of GCA patients treated with GCs between 2007 and 2014, 68 newly-diagnosed GCA with LVLs by imaging were detected. All investigators were members of Japan Research Committee of the Ministry of Health, Labour, and Welfare for Intractable Vasculitis (JPVAS). Poor treatment outcomes (non-achievement of clinical remission by week 24 or relapse during 104 weeks) were primarily evaluated. Cumulative rates and median time to the first event were analyzed by the Kaplan-Meier method and the log-rank test. Associated factors with the outcomes were analyzed by using the Cox proportional hazard model.Results:The mean age was 70.5 years, and 70.6% were women. Twenty-seven (39.7%) of the 68 patients were diagnosed as having GCA by both positive temporal artery biopsy and positive imaging, and 41 (60.3%) by positive imaging. Aortic lesions were detected in 72.1% (group 2, n=49) of the 68 GCA patients with LVLs. Patients without aortic lesions were categorized into two phenotypes: large-vessel GCA with subclavian lesions (group 1, n=9) and atypical large-vessel GCA without subclavian lesions (group 3, n=10). Cranial lesions were observed in 66.7%, 55.1%, and 80.0% in the group 1, 2, and 3, respectively. The initial mean dose (SD) of prednisolone was 0.74 (0.26) mg/kg/day, and 20.6 % received methotrexate for remission induction therapy. Baseline dose of GCs and mean time to achievement of low-dose GCs (prednisolone ≤ 5 mg/day) was not significantly different among the three groups.Overall, 35 (51.5%) of the 68 patients had the event of poor treatment outcomes. Eleven patients were not able to achieve clinical remission by week 24. Relapse after achievement of clinical remission was reported in total of 24 patients; 9 between week 0 and 24, 12 between week 24 and 52, 3 between week 52 and 104. The cumulative rate of events of poor treatment outcomes over the two years was 11.1% in patients with group 1, 55.3% in those with group 2, and 88.0% in those with group 3. Mean time to events was significantly different among the three groups. Multivariable analysis showed the risk of poor treatment outcomes was likely to decrease in the group 1 (hazard ratio 0.14 [95% CI 0.02-1.03], p=0.054), while it increased in the group 3 (hazard ratio 2.22 [95% CI 1.06-4.68], p=0.035).Conclusion:The distribution of LVLs were associated with poorer treatment outcomes. A half of the patients with aortic lesions had poor treatment outcomes while subclavian arteritis without aortic lesions had better clinical outcomes. Atypical large vessel-GCA without the aortic and subclavian artery involvement was the worst prognostic phenotype of LV-GCA. Extent of LVLs by imaging should be considered when determining the treatment strategy for GCA.References:[1]Sugihara T, et al.

Background
Left atrial (LA) function is impaired in heart failure with preserved ejection fraction (HFpEF). However, the association between LA longitudinal strain and heart failure (HF) events in patients with HFpEF is still unknown. We evaluated whether LA strain measurements would be useful to predict hospitalizations for worsening HF in this study.
Methods
This study included 121 patients (Male 73, Female 48) with HFpEF who had echocardiogram at our institute (Age = 76 ± 14y, Left ventricular ejection fraction; LVEF = 63 ± 8%). Patients with atrial fibrillation were excluded. LA longitudinal strain was measured by speckle-tracking echocardiography, using TOMTEC imaging system. The endpoints were hospitalizations for worsening HF.
Results
During follow-up period of 319 ± 269 days, 33 patients (27%) experienced hospitalizations for worsening HF. LA strain was markedly lower in patients with HF events at 11.3 ± 5.6, whereas LA strain was higher at 20.3 ± 10.1 in patients without HF events. Kaplan-Meier analysis demonstrated a significant separation of survival curves stratified by median value of LA strain (Figure).
Conclusions
LA dysfunction in HFpEF is associated with a higher risk of HF hospitalization, and LA strain measurements would be useful to predict HF events.

Background
Measuring pulmonary vascular resistance (PVR) is essential for diagnosing pulmonary hypertension. PVR can be estimated from a simple ratio of tricuspid regurgitation velocity (TRV) to time-velocity integral of flow through right ventricular outflow tract (RVOT) (Abbas equation), but this relationship has been shown to be unreliable in patients with high PVR. Once PVR is elevated, there is an increased pressure wave reflected from the peripheral of pulmonary artery (PA). We tested the hypothesis that assessing PA wave reflection could be an alternative method for estimating PVR.
Methods
This study recruited 83 patients (69 ± 14 years old, 44 men), including 41 patients with left-sided heart disease, 23 patients with pulmonary arterial hypertension and 19 patients with chronic thromboembolic pulmonary hypertension. PA wave reflection was assessed by separating PA pressure waveform derived from a Doppler tracing of TRV into forward and backward pressure (Pf and Pb), using a velocity profile at RVOT. This separation was based on the concept of wave intensity. PVR was estimated using Abbas equation. Pb and PVR by Abbas equation were compared for the correlations with direct measurement of PVR by right heart catheterisation within 48 hours after echocardiography.
Results
Figure A illustrates Pb and Pf waveforms obtained from a patient with chronic thromboembolic pulmonary hypertension. Pb increased from mid systole and formed a late peak of PA pressure waveform. Pb correlated strongly with PVR by catheter (figure B), whereas PVR by Abbas equation underestimated PVR especially when PVR was high, resulting in a moderate correlation (figure C). Receiver-operator characteristic curves showed a higher accuracy of Pb for identifying PVR > 3WU as well as 6WU, compared with PVR by Abbas equation (figure D and E).
Conclusions
This novel echocardiographic method for assessing PA wave reflection helps diagnose the severity of pulmonary hypertension.

Abstract
Purpose: This study evaluated the effect of an aromatic silane compound and acidic functional monomer on the bond strength of fused quartz.
Materials and Methods: A total of 264 disk specimens were fabricated from fused quartz for shear bond testing. Two silane compounds were used: 3-(trimethoxysilyl)propyl methacrylate (3-TMSPMA) and 3-(4-methacryloyloxyphenyl) propyltrimethoxysilane (3-MPPTS). As acidic functional monomers, 4-methacryloyloxyethyl trimellitate (4-MET) and 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) were used. The disks were primed with one of each silane compound with or without the acidic functional monomer of the same molarity. The specimens were bonded with a tri-n-butylborane (TBB) initiated luting material. The shear bond strength was determined before and after 10,000 thermocycles. Bond strength was statistically evaluated with Kruskal-Wallis, Mann-Whitney U-, and Steel- Dwass tests. To test dye penetration, the specimens were immersed in 0.5 wt% fuchsin solution for 24 h after priming with each condition, bonding, and 10,000 thermocycles. The dye penetration area was determined by observing the backside of the bonded specimen with an optical microscope. The relationship between the shear bond strength and dye penetration ratio was analyzed with Spearman’s rank correlation test.
Results: The highest post-thermocycling bond strengths in the 1 mol% and 2 mol% groups were 3-TMSPMA + 10- MDP and 3-MPPTS + 10-MDP. Spearman’s rank correlation coefficient between shear bond strength and dye penetration area was γ = -0.7519, indicating a strong negative correlation.
Conclusion: The surface treatments of 3-TMSPMA and 3-MPPTS combined with 10-MDP yielded higher bond strength after 10,000 thermocycles than those combined with 4-MET, despite the similarity in molarity. The shear bond strength was negatively correlated with the dye penetration area.

Abstract
The distribution of defects and dislocations in graphene layers has become a very important concern with regard to the electrical and electronic transport properties of device applications. Although several experiments have shown the influence of defects on the electrical properties of graphene, these studies were limited to measuring microscopic areas because of their long measurement times. Here, we successfully imaged various local defects in a large area of chemical vapor deposition graphene within a reasonable amount of time by using lock-in thermography (LIT). The differences in electrical resistance caused by the micrometer-scale defects, such as cracks and wrinkles, and atomic-scale domain boundaries were apparent as nonuniform Joule heating on polycrystalline and epitaxially grown graphene. The present results indicate that LIT can serve as a fast and effective method of evaluating the quality and uniformity of large graphene films for device applications.

Abstract
The castability, mechanical properties, and fracture characteristics of Ti-15Mo-5Zr-3Al alloy were compared with those of Ti-6Al-7Nb alloy and pure titanium (CP Ti) for application of this β-type titanium alloy in cast dental prostheses. Cast specimens were prepared with a centrifugal casting machine. A tensile test was performed according to ISO standard 22674. The castability index for Ti-15Mo-5Zr-3Al was lower than those for Ti-6Al-7Nb and CP Ti. The tensile strength of Ti-15Mo-5Zr-3Al was 852 MPa, which was lower than that of Ti-6Al-7Nb and higher than that of CP Ti. The proof strength of Ti-15Mo-5Zr-3Al was 799 MPa, which was comparable to that of Ti-6Al-7Nb and higher than that of CP Ti. The elastic modulus of Ti-15Mo-5Zr-3Al was 81.0 GPa, which was lower than the values for Ti-6Al-7Nb and CP Ti. Elongation of Ti-15Mo-5Zr-3Al was 5.1%, which was comparable to that of Ti-6Al-7Nb and less than that of CP Ti. The shape of the fractured segment was narrower for Ti-15Mo-5Zr-3Al than for Ti-6Al-7Nb and CP Ti. The deformation characteristics of Ti-15Mo-5Zr-3Al may result in decreased stress relative to increased strain during plastic deformation in the stress-strain diagram. In conclusion, Ti-15Mo-5Zr-3Al alloy has a low elastic modulus and exhibits limited ductile plastic deformation in cast dental prostheses.

Abstract
This study aimed to investigate how different compositions of experimental silane-based primers in a methyl methacrylate solution containing 3-(trimethoxysilyl)propyl methacrylate (3-TMSPMA) or 3-(4-methacryloyloxyphenyl)propyl trimethoxysilane (3-MPPTS) might act as silicon dioxide bonding agents. With or without post-silanization heat treatment, primer-treated quartz discs were bonded using the MMA-TBB resin and their bond strengths were evaluated. The disks were primed with one of the following materials: 1 mol% 3-TMSPMA, 2 mol% 3-TMSPMA, 1 mol% 3-MPPTS, and 2 mol% 3-MPPTS. Shear bond strength was determined both before and after thermocycling. Statistical analyses were performed with non-parametric procedure (Kruskal-Wallis, Mann-Whitney U, and Steel-Dwass tests). Both primers were effective with heat treatment to enhance bonding between quartz and the MMA-TBB, and the bonding durability of the 1 and 2 mol% 3-MPPTS (16.8 and 24.9 MPa) with heat groups was significantly higher than in the 1 and 2 mol% 3-TMSPMA (5.4 and 9.8 MPa) with heat groups.

Abstract
The purpose of this study was to evaluate the gloss and surface roughness behaviors of newly developed CAD/CAM composite blocks with different filler contents and characteristics. The gloss and surface roughness were quantified before and after a toothbrush dentifrice abrasion test; the results were compared to the gloss and surface roughness of a ceramic CAD/CAM block. Knoop hardness was determined before abrasion test. The results were analyzed by ANOVA, Tukey HSD, and Dunnett t test (p<0.05). The rank order of Knoop hardness was as follows: Vita Mark II>Vita Enamic>Gradia block>Shofu Block HC, Lava Ultimate≥Katana Avencia block≥Cerasmart. After toothbrush abrasion, a significant difference in the gloss unit was detected between the Shofu Block HC material and the ceramic block. The Ra and Rz of the Cerasmart and Shofu Block HC materials were significantly larger than those of the ceramic block after toothbrush abrasion.

Abstract
Clamshell incision is a standard approach for bilateral lung transplantation, providing a good operative field; however, once wide dehiscence occurs, its management is sometimes difficult because of intense immunosuppression and malnutrition of the recipient. A 22-year-old man with idiopathic pulmonary arterial hypertension underwent cadaveric bilateral lung transplantation through a clamshell incision using standard cardiopulmonary bypass. He developed wound dehiscence on postoperative day (POD) 20 that resulted in exposure of the bilateral fifth ribs and open pneumothorax. Considering the extreme malnutrition and emaciation of the recipient, we avoided initial closure of the dehiscence. After the debridement of necrotic tissue, negative pressure wound therapy was initiated on POD 25 and was continued for approximately 6 months with trafermin spray application. Eventually, the wound, including the fifth ribs, was completely covered with granulation tissue except for the wire tying the sternum. On POD 217, the patient underwent removal of the sternal wire followed by split-thickness skin grafting. His wound was successfully closed and he was discharged without activity limitation on POD 265.

Abstract
Mutations in SPATA5 have recently been shown to result in a phenotype of microcephaly, intellectual disability, seizures, and hearing loss in childhood. Our aim in this report is to delineate the SPATA5 syndrome as a clinical entity, including the facial appearance, neurophysiological, and neuroimaging findings. Using whole-exome sequencing and Sanger sequencing, we identified three children with SPATA5 mutations from two families. Two siblings carried compound heterozygous mutations, c.989_991del (p.Thr330del) and c.2130_2133del (p.Glu711Profs*21), and the third child had c.967T>A (p.Phe323Ile) and c.2146G>C (p.Ala716Pro) mutations. The three patients manifested microcephaly, psychomotor retardation, hypotonus or hypertonus, and bilateral hearing loss from early infancy. Common facies were a depressed nasal bridge/ridge, broad eyebrows, and retrognathia. Epileptic spasms or tonic seizures emerged at 6-12 months of age. Interictal electroencephalography showed multifocal spikes and bursts of asynchronous diffuse spike-wave complexes. Augmented amplitudes of visually evoked potentials were detected in two patients. Magnetic resonance imaging revealed hypomyelination, thin corpus callosum, and progressive cerebral atrophy. Blood copper levels were also elevated or close to the upper normal levels in these children. Clinical delineation of the SPATA5-related encephalopathy should improve diagnosis, facilitating further clinical and molecular investigation.

Abstract
Targeting cell motility, which is required for dissemination and metastasis, has therapeutic potential for ovarian cancer metastasis, and regulatory mechanisms of cell motility need to be uncovered for developing novel therapeutics. Invasive ovarian cancer cells spontaneously formed protrusions, such as lamellipodia, which are required for generating locomotive force in cell motility. Short interfering RNA screening identified class II phosphatidylinositol 3-kinase C2β (PI3KC2β) as the predominant isoform of PI3K involved in lamellipodia formation of ovarian cancer cells. The bioactive sphingolipid ceramide has emerged as an antitumorigenic lipid, and treatment with short-chain C6-ceramide decreased the number of ovarian cancer cells with PI3KC2β-driven lamellipodia. Pharmacological analysis demonstrated that long-chain ceramide regenerated from C6-ceramide through the salvage/recycling pathway, at least in part, mediated the action of C6-ceramide. Mechanistically, ceramide was revealed to interact with the PIK-catalytic domain of PI3KC2β and affect its compartmentalization, thereby suppressing PI3KC2β activation and its driven cell motility. Ceramide treatment also suppressed cell motility promoted by epithelial growth factor, which is a prometastatic factor. To examine the role of ceramide in ovarian cancer metastasis, ceramide liposomes were employed and confirmed to suppress cell motility in vitro. Ceramide liposomes had an inhibitory effect on peritoneal metastasis in a murine xenograft model of human ovarian cancer. Metastasis of PI3KC2β knocked-down cells was insensitive to treatment with ceramide liposomes, suggesting specific involvement of ceramide interaction with PI3KC2β in metastasis suppression. Our study identified ceramide as a bioactive lipid that limits PI3KC2β-governed cell motility, and ceramide is proposed to serve as a metastasis-suppressor lipid in ovarian cancer. These findings could be translated into developing ceramide-based therapy for metastatic diseases.

Abstract
BACKGROUND AND PURPOSE Inflammation and degeneration of the intracranial saccular aneurysm wall play a major role in aneurysm formation, development and subsequent rupture. The aim of this study was to characterize the walls of unruptured intracranial aneurysms by using a hybrid of opposite-contrast MRA at 3T. MATERIALS AND METHODS Fourteen consecutive patients with 17 unruptured intracranial aneurysms who initially underwent clipping surgery were prospectively evaluated. All aneurysms were scanned preoperatively by using a hybrid of opposite-contrast MRA in 3T high-resolution MR imaging. We classified intraoperative findings of atherosclerotic plaques in the aneurysms into 3 grades: grade A (major plaques), grade B (minor plaques), and grade C (no plaques). The contrast ratio of the high-intensity area was also measured relative to the background low-intensity area inside the carotid artery. RESULTS Findings from preoperative plaque imaging of the aneurysm corresponded to the intraoperative findings in 15 of 16 aneurysms (excluding 1 that was impossible to visualize in its entirety due to anatomic reasons). Overall sensitivity and specificity of the hybrid of opposite-contrast MRA were 88.9% and 100%, respectively. During the operation, 4 aneurysms were classified as grade A; 5, as grade B; and 7, as grade C. The means of the contrast ratio for grades A, B, and C were 0.72 ± 0.03, 0.34 ± 0.30, and -0.02 ± 0.09, respectively. CONCLUSIONS The hybrid of opposite-contrast MRA can detect visible atherosclerotic plaques in the unruptured aneurysm wall, and the contrast ratio in intracranial aneurysms correlated with their presence and extent. A study including a larger series is needed to validate the diagnostic potential of this imaging technique.

Abstract
UNLABELLED The stem cell compartment in the esophageal epithelium is possibly located in the basal layer. We have identified significant expression of Smad2/3, phosphorylated at specific linker threonine residues (pSmad2/3L-Thr), in the epithelial cells of murine stomach and intestine, and have suggested that these cells are epithelial stem cells. In this study, we explore whether pSmad2/3L-Thr could serve as a biomarker for esophageal stem cells. We examined esophageal tissues from normal C57BL/6 mice and those with esophagitis. Double immunofluorescent staining of pSmad2/3L-Thr with Ki67, CDK4, p63, or CK14 was performed. After immunofluorescent staining, we stained the same sections with hematoxylin-eosin and observed these cells under a light microscope. We used the 5-bromo-2-deoxyuridine (BrdU) labeling assay to examine label retention of pSmad2/3L-Thr immunostaining-positive cells. We collected specimens 5, 10, 15 and 20 days after repeated BrdU administrations and observed double immunofluorescent staining of pSmad2/3L-Thr with BrdU. In the esophagus, pSmad2/3L-Thr immunostaining-positive cells were detected in the basal layer. These cells were detected between Ki67 immunostaining-positive cells, but they were not co-localized with Ki67. pSmad2/3L-Thr immunostaining-positive cells showed co-localization with CDK4, p63, and CK14. Under a light microscope, pSmad2/3L-Thr immunostaining-positive cells indicated undifferentiated morphological features. Until 20 days follow-up period, pSmad2/3L-Thr immunostaining-positive cells were co-localized with BrdU. pSmad2/3L-Thr immunostaining-positive cells significantly increased in the regeneration phase of esophagitis mucosae, as compared with control mice (esophagitis vs. CONTROL 6.889 ± 0.676/cm vs. 4.293 ± 0.659/cm; P < 0.001). We have identified significant expression of pSmad2/3L-Thr in the specific epithelial cells of murine esophagi. We suggest that these cells are slow-cycling epithelial stem-like cells before re-entry to the cell cycle.

Abstract
Monte Carlo simulations of coronene molecules in single-walled carbon nanotubes (SWCNTs) and dicoronylene molecules in SWCNTs are performed. Depending on the diameter D of the encapsulating SWCNT, regimes favoring the formation of ordered, one-dimensional (1D) stacks of tilted molecules (D ≤ 1.7 nm for coronene@SWCNT, 1.5 nm ≤ D ≤ 1.7 nm for dicoronylene@SWCNT) and regimes with disordered molecular arrangements and increased translational mobilities enabling the thermally induced polymerization of neighboring molecules resulting in the formation of graphene nanoribbons (GNRs) are observed. The results show that the diameter of the encapsulating nanotube is a crucial parameter for the controlled synthesis of either highly ordered 1D structures or GNR precursors.

Abstract
INTRODUCTION In an imperforate anus, colostography often fails to identify recto-urethral fistula (RUF). Thus, surgeons must always assume an RUF is present, despite colostography findings, and dissect the distal rectal pouch (RP) with caution. We report the usefulness of intraoperative colonoscopy (IOC) for excluding RUF and, thus, facilitating safe dissection of the RP. METHODS We used IOC in six cases of imperforate anus. All had right transverse colostomy initially after birth. Distal colostography excluded RUF in five cases and was inconclusive in one. Laparoscopy was used to free the RP carefully from the bladder neck in all cases. Near the prostate, a 4-mm fine, flexible colonoscope was inserted into the RP through the anterior rectal wall to observe the laparoscopic dissection of the RP, which was attached closely to the prostate/bulbar urethra intraluminally to prevent injury to the urethra. The mucosa of the distal end of the RP was mucosectomized or diathermied, and the colon was pulled-through. Mean age at surgery was 11 months. RESULTS IOC excluded RUF under direct vision in all cases, which enabled the dissection of the RP to be monitored and to proceed smoothly. At follow-up (mean: 31 months), all cases were well. CONCLUSIONS IOC can be used to exclude RUF and facilitate safe dissection of the RP in imperforate anus.

Abstract
INTRODUCTION Laparoscopic appendectomy (LA) can be performed safely and effectively using endoloops (EL) or endostaples (ES). We compared EL and ES for stump closure during LA for complicated appendicitis in children. METHODS All LA for complicated appendicitis performed between July 2005 and August 2009 were assessed prospectively. EL were used in 37 procedures and ES in 31. Apart from choice of technique which was the personal preference of the attending surgeon, all patients were managed according to the same intraoperative and postoperative protocols. RESULTS There was no significant difference between mean age at operation; gender ratio; mean preoperative and postoperative white blood cell; mean preoperative and postoperative white blood cell C-reactive protein; histopathology; mean operating time (EL: 71 minutes; ES: 64 minutes); mean hospitalization (EL: 5.3 days; ES: 5.1 days); febrile period (EL: 2.1 days; ES: 1.9 days); white blood cell normalization (EL: 2.6 days; ES: 2.4 days); and intravenous antibiotic usage (EL: 3.8 days; ES: 3.7 days). There were no intraoperative complications or ICU admissions in either group, but two EL cases required conversion to open surgery (P=NS). Incidences of intra-abdominal abscess (EL: n=1 or 2.7%; ES: n=1 or 3.2%), transient ileus (EL: n=2 or 5.4%; ES: n=2 or 6.4%), small bowel obstruction (EL: n=0; ES: n=0), and wound infection (EL: n=1 or 2.7%; ES: n=1 or 3.2 %) were not significantly different. Rate of rehospitalization for EL was 2.7% (n=1; colitis), and for ES, it was 3.2% (n=1; intra-abdominal abscess) (P=NS). Mean cost for EL was US$890, and for ES, it was US$1300. CONCLUSION This is the first prospective study comparing EL and ES during LA for complicated appendicitis in children. ES is more expensive, but there was no significant difference in morbidity for this technique, particularly with regard to incidence of postoperative intra-abdominal abscess.

Abstract
OBJECTIVES The objective of this study was to evaluate and compare our perioperative outcomes for open abdominal aortic aneurysm (AAA) between the pre-endovascular aneurysm repair (pre-EVAR) and EVAR eras and to analyse whether the AAA that was excluded from EVAR could affect the perioperative outcome. MATERIALS AND METHODS The Kurume University Hospital vascular registry was reviewed to identify all patients undergoing an elective open AAA repair from January 2004 through November 2006 (pre-EVAR era, n = 99) and from December 2006 through June 2010 (EVAR era, n = 125). The early clinical outcomes between the two groups were compared. RESULTS In the EVAR era, the proportion of EVAR in all elective AAA repairs was 43.4%. The EVAR era had a significantly higher proportion of very elderly patients over 80 years of age (23.2% vs. 11.1%, P = 0.0391). The morbidity rates were similar between the two groups (22.3% vs. 24,8%) and the mortality rate was 0% for both. CONCLUSION Despite the increased complexity of OAR in the EVAR era, we believe that OAR remains a valid procedure for AAA repair.

Abstract
Cryopreserved boar spermatozoa are not routinely available to swine artificial insemination (AI) because conception and farrowing rates, along with litter size, have remained low. We have reported the positive roles of seminal plasma in frozen–thawed sperm functions (Okazaki et al. 2009 Theriogenology 71, 491–498). Moreover, the injection of seminal plasma to uterus with frozen–thawed spermatozoa significantly increased the implantation rate. Thus, the factors in seminal plasma act not only on sperm but also on uterus to induce successful fertilization and implantation in pig AI using cryopreserved spermatozoa. To test this hypothesis, we identified the factors in seminal plasma and then developed novel pig AI method using cryopreserved spermatozoa. The sperm-rich fraction was collected weekly from each boar using the gloved-hand technique. The seminal plasma was removed just after collection by centrifuge and then was frozen as described in our previous study (Okazaki et al. 2009 Theriogenology 71, 491–498). When the frozen–thawed sperm was incubated with Fluo-3/AM to determine the level of intercellular Ca2+, the level of Ca2+ was increased in a time-dependent manner, and spontaneous capacitation that was judged by tyrosine phosphorylation of sperm protein by Western blotting (Shimada et al. 2008 Development 135, 2001–2011), was also induced in post-thawed sperm. The addition of EGTA to thawing solution significantly suppressed the Ca2+-induced capacitation. Moreover, the treatment increased fertilization rate in in vitro fertilization and in vivo in artificial insemination as similar as those in sperm with seminal plasma. The same number of blastocyst was collected from uterus by AI using post-thawed sperm with EGTA. However, the pregnancy rate remained low, and the number of leukocytes in the uterus was increased. In the next experiment, we examined in seminal plasma, the level of cortisol that has been known to play an important role in controlling immune function. The results showed that cortisol (1.0 ng mL–1) was detected in seminal plasma. When the sows of natural oestrus were twice artificial inseminated with or without cortisol, the injection of cortisol (5 μg/50 mL) to uterus with sperm significantly decreased the number of leukocytes in the uterus or endometrium at 24 to 36 h after AI. The low number of leukocytes in the uterus was similar to that in uterus injected fresh semen. The cortisol injection significantly increased the implantation rate and litter size of sows as compared to AI without cortisol (implantation rate; 83% v. 51%, litter size; 10.6 v. 7.3). From these results, we concluded that the injection of cortisol with frozen–thawed spermatozoa by EGTA-containing solution was a novel method of pig AI using cryopreserved spermatozoa.

Abstract
Epididymal spermatozoa are one of the available male germ cells for cryopreservation. It has been reported that frozen–thawed porcine epididymal spermatozoa have a high fertilization competence in vitro as compared with that in ejaculated one. However, there is little information about reproductive performance, such as conception rate or litter size, after artificial insemination (AI) using frozen–thawed epididymal spermatozoa. Recently, we demonstrated that the addition of seminal plasma to thawing solution improves membrane and acrosomal integrity, and enhanced both in vivo and in vitro fertilizing activity of frozen–thawed ejaculated spermatozoa. Moreover, the injection of seminal plasma to uterus with frozen–thawed spermatozoa significantly increased the number of implantation site (Okazaki et al. 2009 Theriogenology 71, 491–498). Thus, to apply those positive functions of seminal plasma to AI using frozen–thawed epididymal sperm, in this study, we added seminal plasma to thawing solution and then analysed the sperm functions including AI test using frozen–thawed epididymal spermatozoa. Epididymal spermatozoa collected by flushing caudal epididymis were frozen as described in our previous study (Okazaki et al. 2009). Frozen-spermatozoa were thawed in Modena solution with or without different percentages of seminal plasma. Protein tyrosine phosphorylation as a marker of capacitation was detected by western blotting. To examine the reproductive performance, the sows of natural oestrus were artificially inseminated two times (5 × 109 50 mL–1 per injection). When the frozen–thawed ejaculated or epididymal sperm was incubated up to 6 h, the motility of epididymal sperm was significantly higher than that of ejaculated sperm (19.6 v. 37.6%). However, the acrosomal membrane was damaged in epididymal sperm group at 3-h incubation period (15.2 v. 36.0%). The addition of seminal plasma [0, 10, 15, 20% (v/v)] in Modena solution protected the acrosomal injury (3 h; 35.2, 19.5, 15.6, 14.6%) and maintained high rate of motility (6 h; 38.8, 48.8, 62.5, 60.0%) in a dose-dependent manner. Furthermore, the addition of seminal plasma suppressed the expression of the 15 kDa phosphoprotein (early capacitation status), and the maximum effect was detected at 15% (v/v) seminal plasma. When the frozen–thawed epididymal spermatozoa with 15% (v/v) seminal plasma were artificially inseminated to swine (n = 15), the conception rate and the mean number of litter size were increased as compared with control (93 v. 43%, 10.0 v. 5.0). From these results, we concluded that the addition of seminal plasma to thawing solution was a beneficial method for artificial insemination using frozen–thawed epididymal spermatozoa in the pig.

Abstract
A 72-year-old man was admitted to our hospital due to abnormal shadow in the right hilum by a routine chest X-ray. When we had another look at a chest X-ray that had been taken 6 years before, we had found a pulmonary nodule of 18 mm in size. The chest X-ray and computed tomography (CT) taken at admission showed a round nodule with calcification in the same site, with increasing in size to 30 mm. The tumor could not be clinically diagnosed and the surgery was scheduled because the nodule had grown and the possibility of a malignant tumor was suggested. At surgery, the tumor was easily enucleated and the pathological diagnosis was chondromatous hamartoma. Although pulmonary hamartoma is a benign tumor, operation should be performed when the tumor had grown.

Abstract
Systemic lupus erythematosus (SLE) is a chronic disease with multiple pathologies that can affect every organ system of the body including central nervous system. Intracerebral aneurysms and subarachnoid hemorrhage (SAH) are one of comparatively rarer manifestations of central nervous system SLE. Here we present a case of known SLE complicated by the rupture of intra cerebral aneurysm at basilar artery tip which was successfully treated with endovascular coiling.

Abstract
The aim of this study was to clarify the nature of the clonal lymphocyte infiltration in Sjögren's syndrome (SS) patients associated with lymphoproliferative disorders. We examined B cell clonality in lymphoproliferative tissues from six primary SS patients associated with lymphoproliferative disorders or lymphoma by cloning and sequencing of the gene rearrangement of the immunoglobulin heavy chain complementarity determining region 3 (IgVH-CDR3). Three patients with sequential observation showed progressional clonal expansion with the presence of the same subclone in different tissues during the course of disease. Among them, one patient developed mucosa-associated lymphoid tissue (MALT) lymphoma in glandular parotid. The other three SS patients concomitant with malignant B cells lymphomas showed different clonal expansion of B cells between nodal sites and salivary glands. The cloanality analysis indicated that monoclonal B cell population could spread from one glandular site to another site during the course of SS, suggesting that the malignant clone may arise from the general abnormal microenvironment, not restricted to the glandular tissue, in some SS patients.

Abstract
A 17-month-old girl who had been followed up as an extremely-low-birth-weight infant presented with hepatoblastoma in the right lobe of her liver. Preoperative angiography revealed an absence of the portal vein, and the visceral venous return was through the left renal vein into the inferior vena cava. No liver dysfunction and no jaundice were found; however, a marked elevation of the alpha-fetoprotein level was noted. She underwent a typical right hepatic lobectomy successfully after chemotherapy and has no evidence of recurrence 6 months after surgery.
