Abstract
INTRODUCTION Contour maps enable risk classification of GIST recurrence in individual patients within 10 postoperative years. Although contour maps have been referred to in Japanese guidelines, their usefulness and role in determining indications for adjuvant therapy is still unclear in Japanese patients. The aims of this study are to investigate the validity of contour maps in Japanese patients with GIST and explore the new strategy for adjuvant therapy. MATERIALS AND METHODS A total of 1426 Japanese GIST patients who were registered to the registry by the Kinki GIST Study Group between 2003 and 2012 were analyzed. Patients who had R0 surgery without perioperative therapy were included in this study. The accuracy of contour maps was validated. RESULTS Overall, 994 patients have concluded this study. Using contour maps, we validated the patients. The 5-year recurrence-free survival rates of patients within the GIST classification groups of 0-10%, 10-20%, 20-40%, 40-60%, 60-80%, 80-90%, and 90-100% were 98.1%, 96.6%, 92.3%, 48.0%, 37.3%, 41.0% and 42.4%, respectively. We confirmed that this classification by contour maps was well reflected recurrence prediction. Further, in the high-risk group stratified by the modified National Institutes of Health consensus criteria (m-NIHC), the 10-year RFS rate was remarkably changed at a cutoff of 40% (0-40% group vs. 40-100% group: 88.7% vs. 50.3%, p < 0.001). CONCLUSION Contour maps are effective in predicting individual recurrence rates. And it may be useful for the decision of individual strategy for high-risk patients combined with m-NIHC.

Abstract
BACKGROUND & AIMS Epithelial disruption in eosinophilic esophagitis (EoE) encompasses both impaired differentiation and diminished barrier integrity. We have shown that lysyl oxidase (LOX), a collagen cross-linking enzyme, is up-regulated in the esophageal epithelium in EoE. However, the functional roles of LOX in the esophageal epithelium remains unknown. METHODS We investigated roles for LOX in the human esophageal epithelium using 3-dimensional organoid and air-liquid interface cultures stimulated with interleukin (IL)13 to recapitulate the EoE inflammatory milieu, followed by single-cell RNA sequencing, quantitative reverse-transcription polymerase chain reaction, Western blot, histology, and functional analyses of barrier integrity. RESULTS Single-cell RNA sequencing analysis on patient-derived organoids revealed that LOX was induced by IL13 in differentiated cells. LOX-overexpressing organoids showed suppressed basal and up-regulated differentiation markers. In addition, LOX overexpression enhanced junctional protein genes and transepithelial electrical resistance. LOX overexpression restored the impaired differentiation and barrier function, including in the setting of IL13 stimulation. Transcriptome analyses on LOX-overexpressing organoids identified an enriched bone morphogenetic protein (BMP) signaling pathway compared with wild-type organoids. In particular, LOX overexpression increased BMP2 and decreased the BMP antagonist follistatin. Finally, we found that BMP2 treatment restored the balance of basal and differentiated cells. CONCLUSIONS Our data support a model whereby LOX exhibits noncanonical roles as a signaling molecule important for epithelial homeostasis in the setting of inflammation via activation of the BMP pathway in the esophagus. The LOX/BMP axis may be integral in esophageal epithelial differentiation and a promising target for future therapies.

Abstract
BACKGROUND Body weight loss (BWL) is a serious complication of gastrectomy in patients with gastric cancer (GC). Nutritional intervention alone is inadequate for preventing BWL, and a new approach is needed. Oral frailty among older adults has recently attracted attention. This study aimed to investigate masticatory ability and BWL after gastrectomy. METHODS This was a single-center, retrospective study. Functional tooth units (FTU) were used to measure masticatory ability. Patients with FTU < 4 were defined as low FTU group and FTU ≥ 4 as high FTU group. The BWL was compared between the two groups. RESULTS Sixty patients who underwent distal gastrectomy for GC from March 2022 to January 2023 were enrolled in this study. The median FTU was 3 (range 0-12). The low-FTU group (FTU < 4) included 29 patients, while the high-FTU group (FTU ≥ 4) included 31 patients. The %BWL in the low FTU group was significantly higher than that in the high-FTU group at 1 and 3 months (p = 0.003 and p = 0.017, respectively). The risk factors associated with a %BWL > 5 at 1 and 3 months after gastrectomy were analyzed using logistic regression analysis. Only FTU < 4 was an independent risk factor after gastrectomy for GC in univariate and multivariate analyses (p = 0.028 and p = 0.006, respectively). CONCLUSIONS Low FTU in patients with preoperative GC was a risk factor for %BWL 1 and 3 months postoperatively. Appropriate oral interventions may be useful in improving the postoperative nutritional status after gastrectomy.

Abstract
BACKGROUND The optimal treatment strategy for cT4b esophageal cancer has not been established yet. Although curative surgery is sometimes performed after induction treatments, the prognostic factor of cT4b esophageal cancer cases who underwent R0 resection remains unknown. METHODS A total of 200 patients with cT4b esophageal cancer who underwent R0 resection after induction treatments between 2001 and 2020 in our institute were included in the present study. The relationship between clinicopathological factors and patient survival is evaluated to identify useful prognostic factors. RESULTS The median and 2-year overall survival were 40.1 months and 62.8%, respectively. Disease recurrence occurred in 98 (49%) patients after surgery. Compared to induction chemotherapy alone, chemoradiation-based induction treatments were associated with decreased locoregional recurrence (34.0% vs 60.8%, P = .0077) but increased pulmonary metastases (27.7% vs 9.8%, P = .0210) and dissemination (19.1% vs 3.9%, P = .0139) after surgery. Multivariate analysis of overall survival identified the preoperative C-reactive protein/albumin ratio (hazard ratio 1.7957, P = .0031), response to induction treatments (hazard ratio 2.9663, P = .0009), postoperative pneumonia (hazard ratio 2.3784, P = .0010), and pN (2-3) (hazard ratio 1.5693, P = .0355) as independent prognostic factors. Preoperative C-reactive protein/albumin ratio (hazard ratio 1.6760, P = .0068) and postoperative pneumonia (hazard ratio 1.8365, P = .0200) were also independent prognostic factors for recurrence-free survival. CONCLUSION Curative surgery after induction therapy for cT4b esophageal cancer achieved favorable survival. Preoperative C-reactive protein/albumin ratio, postoperative pneumonia, response to induction treatments, and pN were useful prognostic factors.

Abstract
BACKGROUND Exon 18 D842V, which is a point mutation from aspartic acid to valine at codon 842, is the most frequent mutation in Platelet-Derived Growth Factor Receptor alpha (PDGFRA)-mutated gastrointestinal stromal tumor (GIST). In the Japanese GIST guidelines, no standard systematic therapy is available for this type of GIST, which is refractory after recurrence. Recently, pimitespib (PIMI), a novel heat shock protein 90 (HSP90) inhibitor, was approved for the treatment of advanced GIST in a phase III study. This report presents a case of a long-term response to PIMI in GIST with PDGFRA D842V mutation. CASE PRESENTATION A 55-year-old woman was diagnosed with primary GIST of the stomach and underwent partial gastrectomy. Eight years after the operation, recurrent GISTs were identified as multiple recurrent peritoneal GISTs in the upper right abdomen and pelvic cavity. We administered tyrosine kinase inhibitors, but they achieved poor effects. After failure of the standard treatment, PIMI was administered and achieved a partial response in the patient. The highest reduction rate was 32.7%. After PIMI failed, we performed multiplex gene panel testing, which revealed the PDGFRA D842V mutation. CONCLUSIONS We report the first case of long-term response to PIMI in PDGFRA D842V mutant GIST. Pimitespib may be effective for treating GIST harboring this mutation by inhibiting HSP90.

Abstract
BACKGROUND Imatinib mesylate (IM) is the standard chemotherapy for patients with gastrointestinal stromal tumors (GISTs) and has a favorable safety profile. Pharmacokinetics (PK), such as plasma trough concentration (Cmin), varies among patients, requiring the need for therapeutic drug monitoring (TDM) during IM administration. Despite some reports from overseas, the relationship between Cmin, adverse events (AEs), and treatment efficacy in Japanese patients with GIST has still been lacking. This study aimed to investigate the relationship between IM plasma concentration and AEs in Japanese patients with GISTs. METHODS This retrospective study analyzed the data of 83 patients who underwent IM treatment for GISTs at our institution between May 2002 and September 2021. RESULTS The IM Cmin was associated with any grade of AEs (with AEs vs. without AEs = 1294 (260-4075) vs. 857 (163-1886) ng/mL, P < 0.001), edema (with edema vs. without edema = 1278 (634-4075) vs. 1036 (163-4069) ng/mL, P = 0.017), and fatigue (with fatigue vs. without fatigue = 1373 (634-4069) vs. 1046 (163-4075) ng/mL, P = 0.044). Moreover, a Cmin ≥ 1283 ng/mL was a risk factor for severe AEs. The median progression-free survival (PFS) was 3.04 years in the lowest Cmin tertile (T1, < 917 ng/mL) compared with 5.90 years for T2 and T3 (P = 0.010). CONCLUSION Edema and fatigue are potentially associated with IM plasma trough concentrations of ≥ 1283 ng/mL in Japanese patients with GISTs. Further, maintaining an IM plasma trough concentration above 917 ng/mL may improve PFS.

Abstract
Despite the effectiveness of imatinib, most gastrointestinal stromal tumors (GISTs) develop resistance to the treatment, mainly due to the reactivation of KIT tyrosine kinase activity. Sunitinib, which inhibits the phosphorylation of KIT and vascular endothelial growth factor (VEGF) receptor, has been established as second-line therapy for GISTs. The recently-developed heat shock protein 90 (HSP90) inhibitor pimitespib (PIM; TAS-116) demonstrated clinical benefits in some clinical trials; however, the effects were limited. The aim of our study was therefore to clarify the effectiveness and mechanism of the combination of PIM with sunitinib for imatinib-resistant GISTs. We evaluated the efficacy and mechanism of the combination of PIM with sunitinib against imatinib-resistant GIST using imatinib-resistant GIST cell lines and murine xenograft models. In vitro analysis demonstrated that PIM and sunitinib combination therapy strongly inhibited growth and induced apoptosis in imatinib-resistant GIST cell lines by inhibiting KIT signaling and decreasing auto-phosphorylated KIT in the Golgi apparatus. In addition, PIM and sunitinib combination therapy enhanced antitumor responses in the murine xenograft models compared to individual therapies. Further analysis of the xenograft models showed that the combination therapy not only downregulated the KIT signaling pathway but also decreased the tumor microvessel density. Furthermore, we found that PIM suppressed VEGF expression in GIST cells by suppressing protein kinase D2 and hypoxia-inducible factor-1 alpha, which are both HSP90 client proteins. In conclusion, the combination of PIM and sunitinib is effective against imatinib-resistant GIST via the downregulation of KIT signaling and angiogenic signaling pathways.

Abstract
Carney-Stratakis syndrome (CSS) is a familial syndrome characterized by gastrointestinal stromal tumors (GISTs) and paragangliomas, often at multiple sites. A 34-year-old woman who had undergone resection of gastric GISTs, liver metastases, and a retroperitoneal paraganglioma in her previous hospital was referred to our hospital due to recurrence after 5 years. She presented with two gastric GISTs, a liver tumor, and a peritoneal tumor. As molecular-targeted agents are reported to be ineffective against CSS-related GISTs, we selected surgical resection for the recurrence. We performed laparoscopic local gastrectomy, liver S7 subsegmentectomy, and peritoneal tumor resection. Pathological findings revealed multiple gastric GISTs with liver metastasis and a paraganglioma. The laparoscopic approach could be performed safely, less invasively, and it could be more effective in such cases. This is the first case report of laparoscopic resection for recurrent CSS-related GISTs and paragangliomas.

Abstract
PURPOSE Pancreatic fistula is a severe complication after laparoscopic distal gastrectomy (LDG). We previously evaluated the pancreas-left gastric artery angle (PLA) as a risk indicator for developing a pancreatic fistula after LDG. This study evaluated the incidence of pancreatic fistula with robotic distal gastrectomy (RDG) in comparison to LDG from the view of the PLA. MATERIALS AND METHODS An association between the PLA and the incidence of pancreatic fistula in 165 patients who underwent either RDG (n=45) or LDG (n=120) was investigated retrospectively. RESULTS RDG patients had significantly lower drain amylase values (postoperative day 2) than LDG patients. As opposed to LDG patients, drain amylase values were similar for patients with small (PLA <62 degrees) and large (PLA ≥62 degrees) PLA in RDG patients. CONCLUSION Robotic surgery may reduce the risk of postoperative pancreatic fistula in patients with a small PLA.

Abstract
BACKGROUND Regorafenib is an oral multi-kinase inhibitor that has been established as third-line treatment for patients after the failure of imatinib and sunitinib. However, since clinical data of regorafenib in the Japanese population are still lacking, the management of regorafenib is mainly based on the clinical experience of each oncologist. The aim of this study was to evaluate the efficacy and safety of regorafenib in a Japanese population. METHODS Thirty-three patients treated with regorafenib for metastatic and recurrent gastrointestinal stromal tumors were retrospectively enrolled. This study investigated the anti-tumor effect, including overall survival, progression-free survival, and safety, which was evaluated based on the incidence of adverse events. RESULTS The median overall survival of patients treated with regorafenib was 23.8 months and the 1-year overall survival rate was 80.0%, the median progression-free survival was 7.1 months and the 1-year progression-free survival rate was 40.2%. The responses to regorafenib were partial response in 3 cases (9.1%), stable disease in 17 (51.5%), progressive disease in 10 (30.3%), and non-evaluable in 3 (9.1%). The disease control rate was 54.0%. Treatment-related adverse events were reported in all patients, with the most common being hand-foot syndrome (72.7%), followed by liver damage (36.4%) and diarrhea (27.3%), and six patients (20.0%) were discontinued due to adverse events. CONCLUSION This is the first report of Japanese patients with gastrointestinal stromal tumors treated with regorafenib. Regorafenib showed efficacy and a manageable safety profile in Japanese patients with advanced gastrointestinal stromal tumors, which was comparable with previous studies.

Abstract
INTRODUCTION The pancreas often interferes with the surgical field during laparoscopic gastrectomy (LG) and its disorders cause severe postoperative complications. This study aimed to evaluate the association between the anatomical location of the pancreas and surgical outcome and to investigate the optimal surgical position in LG. METHODS We newly defined the angle formed between the supra-pancreatic region and the root of the left gastric artery (LGA) as the pancreas-LGA angle (PLA). The association between PLA and surgical outcomes in 107 consecutive patients who underwent laparoscopic distal gastrectomy (LDG) was investigated. Then, the change in PLA before and after insertion of the back pillow in 30 patients with gastric cancer was examined. RESULTS The median PLA was 62° (range, 2°-157°). No differences were found in the patient background between patients with small PLA (PLA < 62°; n = 53) and those with large PLA (PLA ≧ 62°; n = 54). The postoperative inflammation response (white blood cells, neutrophils, and C-reactive protein) and amylase concentration in the drainage fluid (D-AMY) were significantly higher in the small PLA group than large PLA group. Multivariable analyses demonstrated that small PLA was an independent risk factor for high D-AMY. After insertion of a back pillow, PLA was noninvasively increased in all patients, and the median PLA was changed to 92° (range, 8°-151°) from 61° (range, 2°-140°). Of 17 patients with small PLA, nine developed large PLA. CONCLUSIONS These results suggest that PLA can become one of the indicators of postoperative complications related to anatomical patient factors in LDG.

Abstract
A 69-year-old man underwent single-incision laparoscopic colectomy for a colon tumor. He had comorbid relapsing polychondritis, an uncommon and intractable chronic inflammatory disease that shows various symptoms and systemically invades the cartilaginous tissue throughout the body. In this case, the bronchial wall was edematous and the glottis was incompetent. Steroids were also administered. Although the patient had high-risk factors for surgical complications, none occurred during the perioperative period. Once the C-reactive protein value returned to within the normal range after surgery, we reduced the steroid dose. This is the first report of single-incision laparoscopic colectomy for a patient with relapsing polychondritis.

Abstract
A 65-year-old man was diagnosed with agammaglobulinemia at the age of 53 years. To investigate the cause of the increased CRP value, CT was performed and revealed thickening of the walls of the ascending colon and rectum. Colonoscopy revealed tumors and stenoses in the ascending colon and rectum. Both tumors were found to be adenocarcinomas in histological examinations. The preoperative diagnosis of the ascending colon and rectal cancers was cT4aN0M0, cStageⅡb. Preoperatively, we administered 10.0 g of immunoglobulin intravenously. We performed laparoscopic right hemicolectomy and high anterior resection with D3 dissection of the lymph node. On postoperative day 1, we again administered 10.0 g of immunoglobulin intravenously. The patient recovered uneventfully and was discharged on postoperative day 13. Laparoscopic colectomy for patients with agammaglobulinemia can be performed safely by administering immunoglobulin during the perioperative period.

Abstract
We report a patient who had Castleman's disease with lymphadenopathy during the treatment of gastric cancer. In May 2017, a 63-year-old man underwent gastrointestinal endoscopy, which revealed a tumor on the posterior wall of the lower part of the stomach. Based on a biopsy, he was diagnosed with suspected adenocarcinoma, Group 4. In June 2017, he visited our hospital, and endoscopic submucosal dissection(ESD)was performed. The pathological diagnosis of the resected specimens was L, Less, 20×10 mm, Type 0-Ⅱc, tub1, pT1a(M), UL(-), ly(-), v(-), pHM0, pVM0, pStage ⅠA. He was referred to our department for the treatment of abdominal lymphadenopathy. His lymphadenopathy was localized in the gastric lesser curvature as an enlarged lymph node 15mm in size, based on the findings of contrast-enhanced CT. On FDG- PET/CT, we found a slight accumulation of SUVmax 2.4 in the early phase in the same lymph node. We could not confirm a diagnosis, and we performed laparoscopic dissection of the lymph node for diagnosis and treatment. The size of the specimen was 14×14mm, surface was smooth, and lymph node was elastic and soft. We found lymphoid follicles with atrophic germinal center using HE staining. We also found increased hyperplastic blood vessels around the germinal center, and he was diagnosed with hypervascular Castleman's disease.

Abstract
A 66-year-old man underwent total gastrectomy for gastric cancer. S-1 was administered as adjuvant chemotherapy. Abdominal CT showed para-aortic lymph node recurrence 31 months after the surgery. There was no other recurrence according to PET-CT, and we performed para-aortic lymph nodes dissection 41 months after the surgery. Lymph node recurrence in the retrocrural space was observed 37 months after the 2nd surgery. We administered S-1 plus L-OHP chemotherapy. After 4 courses, CT revealed that he had achieved complete response, and he has remained disease-free for 79 months after lymph node dissection. Some patients with para-aortic lymph node recurrence after curative gastrectomy may benefit from treatment including chemotherapy and surgical dissection.

Abstract
Metastasis of renal cell carcinoma to the pancreas is a relatively rare condition. We encountered 2 such cases. The first case was a 72-year-old man who underwent a left nephrectomy owing to left renal cancer in 2005. An abdominal dynamic CT scan 12 years after surgery revealed tumors in the pancreatic body and right kidney. A PET-CT scan revealed low intensity uptake of both tumors, and therefore, metastasis of the left renal cell carcinoma to the pancreas was suspected. We then performed partial resections of the pancreatic tail and right kidney. Pathologic findings confirmed that the pancreatic tumor and right renal tumor were metastases of the left renal cell carcinoma. The postoperative course was favorable, and the patient has been followed up in an outpatient setting for 10 months with no signs of recurrence. The second case was a 51- year-old woman with tumors in the left kidney and pancreatic head that were detected by abdominal contrast CT and MRI. We diagnosed the patient with left renal cell carcinoma with metastasis to the pancreas. We performed a radical nephrectomy of the left kidney and full pancreatectomy. Pathologic findings confirmed left renal cell carcinoma, pStage Ⅳ, with metastasis to the pancreas. The postoperative course was favorable without recurrence for 14 years. We report on two cases of metastasis of renal cell carcinoma to the pancreas in patients who underwent radical resections and had favorable postoperative courses, with some bibliographic consideration.

Abstract
The patient was a 79-year-old man. He underwent endoscopic papillectomy for ampullary cancer when he was 70 years old. At the ages of 71 and 73 years, liver metastasis in segment 6 was detected, and radiofrequency ablation(RFA)was performed and adjuvant chemotherapy(gemcitabine, S-1)was administered. At the age of 79 years, recurrence of liver metastasis appeared. Because there were no other metastatic lesions, we performed S6 subsegmentectomy. Five months after the surgery, no recurrence was observed. In general, the prognosis of patients with ampullary cancer with distant metastasis is very poor. This case suggested the efficacy of multidisciplinary treatment, including surgery, RFA, and chemotherapy, in a patient with ampullary cancer with distant metastasis.

Abstract
A 67-year-old woman was diagnosed with rectal cancer using colonoscopy. Computed tomography revealed the so-called superior mesenteric vein rotation sign, and intestinal malrotation was suspected. We planned chemotherapy after the surgical resection of the primary cancer because she had multiple lung metastases. Laparoscopic high anterior resection with D3 dissection of lymph nodes was performed. Intraoperative findings showed a non-rotation type intestinal malrotation and severe intra-abdominal adhesion. However, careful releasing operation enabled the typical approach of laparoscopic surgery for rectal cancer. The postoperative course was generally good, and she was discharged on the 17th postoperative day. The pathological diagnosis was rectal cancer(T3, N0, M1a, pStage Ⅳ). In laparoscopic surgery for colorectal cancer with intestinal malrotation, determining the anatomy of blood vessels and the site of the tumor before surgery is important. Furthermore, awareness that some cases have severe intra-abdominal adhesions even without a history of laparotomy is necessary.

Abstract
We report a patient with brain metastasis of rectal cancer who underwent metastatic tumor resection 3 times. In March 2012, a 76-years-old man, diagnosed with Stage III a rectal cancer, underwent Hartmann's operation. The lung metastasis was confirmed in July and November 2013, surgical resection for pulmonary metastasis was performed 2 times. In January 2016, he had difficulty of speaking, and isolated brain tumor was found. We performed surgical resection of brain metastasis in February 2016. In March and July 2016, the gamma knife radiosurgery was performed for other brain metastasis. In July 2016, he occurred nausea, headache and right identity hemi-blindness. Two new brain tumors were revealed. We performed surgical resection again. Three months after second brain surgery, he had dysarthria and a solitary brain tumor was confirmed. We performed third neurosurgical resection. All tumors of brain were found to be metastasis from rectal cancer in histological study. Currently, 16 months have passed since the first diagnosis of brain metastasis of this patient, and the quality of life was good relatively. The prognosis of the patients with brain metastasis is poor generally. However, this case suggested that multiple surgical resection of brain metastasis could improve prognosis and quality of life of patients. Accumulation of further cases is needed.

Abstract
We report 2 resected cases of patients with non-isolated splenic metastasis of colon cancer. Case 1: A 67-year-old man who underwent partial transverse colectomy and partial hepatectomy for transverse colon cancer and liver metastasis. Approximately 18 months after the operation, splenectomy and partial hepatectomy were performed for metastasis to the spleen and liver. After partial hepatectomy for another recurrence, no signs of new recurrence have been observed for 42 months after splenectomy. Case 2: A 53-year-old woman who presented with bloating. CT and MRI scans revealed masses of the ileocecum, both ovaries, and spleen. We performed right hemicolectomy, total hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy, para-aortic lymphadenectomy, omentectomy, and splenectomy. Histological findings showed cecal cancer metastasizing to the bilateral ovaries and spleen. Metastatic splenic tumor is relatively rare(0.3-7.3%). Splenectomy was reported to be an effective treatment modality for isolated splenic metastasis, while that for non-isolated metastasis is uncertain. Surgical resection should be considered even in non-isolated splenic metastasis cases because of the evidence of long-term survival in case 1.

Abstract
IntroductionSince the discovery of REBa2Cu3O7-y (RE: Rare Earth element, REBCO) superconductors, they have been expected as the best candidates for the power cable application due to its high critical temperature (Tc) and critical current density (Jc). Among those REBCO superconductors, GdBa2Cu3O7-y (GdBCO) have been receiving great interest because they have higher Tc and Jc than YBa2Cu3O7-y [1].GdBCO with various types of precipitates as artificial pinning centers (APCs) have been proposed to minimize the anisotropy of Jc characteristics under the magnetic field. Among those precipitates, BaHfO3 (BHO) was found most effective precipitates as APCs in GdBCO film prepared by pulsed laser deposition (PLD) method [2]. It is therefore necessary to investigate not only the morphologies but also the dispersion of BHO precipitates within the GdBCO, to understand the role of BHO for the superconducting characteristics. In this study, morphologies and dispersions of BHO precipitates were characterized three-dimensional by scanning transmission electron tomography ExperimentalBHO dispersed GdBCO films were fabricated on Hastelloy C-276TM substrates with buffer layers of CeO2/LaMnO3/MgO/ Gd2ZrO7 by PLD method.To observe microstructure of GdBCO film with BHO precipitates, cross-section TEM specimens were prepared by FIB method using Quanta 3D-200 (FEI, USA) with acceleration voltage from 2 to 30 kV. Three-dimensional information such as morphology and dispersion, of BHO precipitates were characterized by electron tomography using STEM-HAADF. Result and discussionFigure 1 shows three-dimensional reconstructed volume of BHO precipitates in GdBCO, which revealed that fine BHO precipitates have rod- and plate-like morphologies with homogeneous dispersion in GdBCO. In addition, growth directions of these precipitates were found with wide angular distributions from growth direction of GdBCO. Anisotropy of Jc in the magnetic fields was probably enhanced by various growth directions and homogeneous dispersion of nanosized BHO within GdBCO.jmicro;63/suppl_1/i26/DFU080F1F1DFU080F1Fig. 1.Three-dimensional reconstructed volume of BHO.

Abstract
Three triterpenoids, betulinic acid, oleanolic acid, and ursolic acid, were isolated as their methyl esters (treatment with diazomethane) from diethyl ether extracts of almond hulls (Nonpareil variety) using flash chromatography and preparative high-performance liquid chromatography. The triterpenoids, which comprised approximately 1% of the hulls, were characterized using chromatographic and spectroscopic methods. These studies demonstrate that almond hulls are a rich source of these triterpenoids, which have reported anti-inflammatory, anti-HIV, and anti-cancer activities.

Abstract
A study is reported on the perception of empty time intervals marked by auditory signals. Nakajima's supplement hypothesis, which states that the subjective duration of a subjectively empty time interval is proportional to its physical duration plus a constant of approximately 80 ms, was examined quantitatively. Although this hypothesis has been used to explain various general aspects of time perception, from a global viewpoint, it has lacked the quantitative data necessary to describe the shape of the psychophysical functions mathematically. In the present study, subjects used two positive numbers to estimate the subjective ratio (m:n) between the durations of two serial or separate empty intervals. The psychophysical functions for empty durations 50-600 ms long could be approximated by a straight line with a positive gamma-intercept, as predicted by the hypothesis. The effective range of the hypothesis could be extended to approximately 1200 ms. A power function (without any modifications) also gave good approximations. The reliability and validity of the supplement hypothesis are discussed.

Abstract
When a human being is placed for several days on a completely defined diet, consisting almost entirely of small molecules that are absorbed from the stomach into the blood, intestinal flora disappear because of lack of nutrition. By this technique, the composition of body fluids can be made constant (standard deviation about 10%) after a few days, permitting significant quantitative analyses to be performed. A method of temperature-programmed gas-liquid partition chromatography has been developed for this purpose. It permits the quantitative determination of about 250 substances in a sample of breath, and of about 280 substances in a sample of urine vapor. The technique should be useful in the application of the principles of orthomolecular medicine.
