Abstract
PURPOSE/OBJECTIVE(S) Palliative radiotherapy is an effective and commonly used treatment for pain relief in metastatic cancer patients. This study aimed to classify the patients to predict their response to palliative radiotherapy. MATERIALS/METHODS This study used the data from our single-center, prospective observational study (UMIN000044984), which included all patients undergoing palliative radiotherapy for the painful tumor, except for postoperative setting or brain metastases. The eligibility criteria were as follows: (1) numerical rating scale (NRS) was two or more before treatment, and (2) underwent palliative radiotherapy between August 2021 and September 2022. Questionnaires for pain site, NRS, and presence/dose of opioids were obtained before, on the last day of treatment, two weeks later, one month later, three months later, and every three months after that. Patients with severe performance status (PS) were contacted by telephone. Pain response was defined to reduce NRS 2 or more at the treated site without an analgesic increase. The primary outcome was the response rate within three months of the treatment. We used multivariable logistic regression to find the independent prognostic factors for the response based on the following covariates: age, sex, PS, body mass index, NRS, history of radiotherapy, treated site, radiographic features (lytic/sclerotic/mixed), metastatic complication, presence/dose of opioids, bone-modifying agents, radiation dose, type of primary tumor, radiosensitivity, number of metastases, and days from diagnosis to treatment. A classification model was created using significant factors, and response rates were calculated for each class. Statistical significance was defined as P<0.05. RESULTS Among 488 targets of 300 patients registered, 366 targets of 261 patients met the criteria. The median age was 65 years, 44% were female, and PS (0/1/2/3/4) was 6/63/18/9/4%. The major type of tumor was gastrointestinal (32%), lung (19%), and breast (12%). Bone metastases were 75% at treated sites. Opioids were used by 72%, BMA was 27%, and chemotherapy was 50%. Re-irradiation rate was 22%. With a median follow-up of 5.8 months, 113 patients were alive, 129 had died, and 20 were lost follow-up. The average NRS was reduced from 6.1 to 3.1 from pretreatment to 3 months later per evaluable 232 targets, resulting in a pain relief rate of 60%. Opioids use (P<0.001) and re-irradiation (P<0.001) were significant factors of poor response in multivariate analysis. In our classification model, 89 targets were classified as class 1 (no opioids & no irradiation history), 211 were class 2 (other than class 1 and 3), and 66 were class 3 (opioids & re-irradiation), were 75/61/36% (P<0.001) of response rate. The 6-month cumulative pain progression rate was 12/22/32% (P<0.001), respectively. CONCLUSION Palliative radiotherapy is highly effective for patients with painful tumors especially for those without previous irradiation history or use of opioids.

Abstract
Abstract:The main purpose of an automatic health testing system (AMHTS) has changed from early detection to primary prevention. Health-risk appraisal is now widely available as a tool of health education aiming at the modification of unhealthy lifestyles. However, the opportunity to offer appropriate health education was less frequent for those who had no particular findings during AMHTS. The results of an AMHTS should be evaluated from the viewpoint of health-risk appraisal, because the system is expected to supply useful information regarding one’s lifestyle. Our system consists of two health-risk appraisal subsystems. One subsystem estimates the degree of improvement in medical indicators after a patient’s lifestyle has been modified. The other subsystem predicts the occurrence of abnormal findings in medical indicators. These health-risk appraisal subsystems provide patients with information about their health-risks, based on their AMHTS results. Our health-risk appraisal subsystems should play an important role in future health education through the application of ordinary AMHTS.

Abstract
Although it has been reported that populations of the Japanese dojo loach Misgurnus anguillicaudatus (Cypriniformes: Cobitidae) belong to two distinct mitochondrial (mt)DNA (Type I and Type II), the taxonomic status of the species remains unresolved. To address this question, nuclear DNA and morphological analyses were performed on M. anguillicaudatus population in the Nakaikemi Wetland, where Type I and Type II lineages are sympatric. Results suggest the existence of a cryptic species (Type I) within the Japanese dojo loach.

Abstract
The plasma 1,25-(OH)2VD3 level in Fanconi syndrome was low but rose rapidly following the administration of 1 alpha-OHVD3. 1 alpha-OHVD3 was administered to 6 patients with different types of Fanconi syndrome. The effect of 1 alpha-OHVD3 proved to be 200-250 times as great as that of vitamin D2. From our results it was suggested that Ca malabsorption due to failure of 1 alpha-hydroxylation of vitamin D in the kidney, together with renal tubular acidosis and hypophosphatemia, is involved in the pathogenesis of the rickets of Fanconi syndrome.

Abstract
We study the nonequilibrium dynamics of a coherently split one-dimensional Bose gas by measuring the full probability distribution functions of matter-wave interference. Observing the system on different length scales allows us to probe the dynamics of excitations on different energy scales, revealing two distinct length-scale-dependent regimes of relaxation. We measure the crossover length scale separating these two regimes and identify it with the prethermalized phase-correlation length of the system. Our approach enables a direct observation of the multimode dynamics characterizing one-dimensional quantum systems.

Abstract
BACKGROUND As there is only one skin procurement organization in Japan the Japan Skin Bank Network (JSBN), all skin grafts procured in Japan are sent by a commercialized delivery system. Preliminarily, bottles containing saline were transported in a cardboard box using a so-called "cooled home delivery service" using a truck with a refrigerated cargo container. During transportation the temperature in the cardboard box increased to 18°C in summer and decreased to -5°C in winter. For these reasons, we investigated whether a newly developed container "Medi Cube" would be useful to transport skin grafts. OBJECTIVES Four bottles with a capacity of 300 mL containing 150 mL of saline in a Medi Cube container were transported from Osaka to the JSBN in Tokyo between 4 PM and 10 AM using a commercialized cooled home delivery service. Two bottles were transported in a Medi Cube container without phase change materials (PCM) in winter and summer, respectively. Another two bottles were transported in the Medi Cube with PCMs in winter. The temperatures inside saline, inside a transportation container, and outside the container, and air temperature were monitored continuously with a recordable thermometer. RESULTS The temperatures inside saline and inside a Medi Cube container were maintained between 3 and 6°C, even when the temperature outside the container increased during parking. The temperature inside a Medi Cube container without PCM decreased to -3°C when the inside of the cargo container was overcooled in winter. However, the temperatures inside saline and inside a Medi Cube container with PCM were between 3 and 6°C, even when the temperature outside the container decreased to below 0°C in winter. CONCLUSION A Medi Cube container with PCM provided a safe, easy, and cost-effective method for overnight transportation of skin grafts.

Abstract
BACKGROUND AND STUDY AIMS We compared the performance efficiency of a newly developed small-caliber colonoscope (PCF-PQ260 L) with passive bending, high force transmission, and an outer diameter of 9.2 mm with that of a standard colonoscope, in female and male patients, particularly with regard to passage through acute angulations or into the proximal colon. PATIENTS AND METHODS A total of 330 patients were randomly allocated to undergo small-caliber (n = 164) or standard (n = 166) colonoscopy. The patients were assessed for pain using a visual analogue scale (0 = none, 100 = extremely painful), and for cecal intubation, withdrawal time, difficulty of colonoscopy, dosage and level of sedation used, and any complications. RESULTS Median maximum pain and overall pain during colonoscopy were significantly lower in the small-caliber group than in the standard group in women (25 vs. 45, P < 0.001 and 15 vs. 26, P = 0.001, respectively), whereas no significant differences were seen in men (8 vs. 10, P = 0.103 and 16 vs. 20, P = 0.166, respectively). Furthermore, no significant differences were seen between groups in cecal intubation rate or time to cecum in all patients or by sex. CONCLUSIONS Use of the small-caliber colonoscope reduced pain in female patients, but offered no advantage over standard colonoscopy in male patients. The performance of the small-caliber colonoscope was equivalent to that of the standard colonoscope in terms of cecal intubation rate and time to cecum, regardless of the sex of the patient.

Abstract
Carcinogenesis and cancer progression, driven by mutations in oncogenes and tumor-suppressor genes, result in biological differences between normal and cancer cells in various cellular processes. Specific genes and signaling molecules involved in such cellular processes may be potential therapeutic targets of agents that specifically interact with the key factors in cancer cells. Increased glucose uptake is fundamental to many solid tumors and well associated with increases in glycolysis and the overexpression of glucose transporters (GLUTs) such as GLUT1 and GLUT3 at the plasma membrane. Here, we used cell-based screening to identify glycogen synthase kinase-3β (GSK-3β) inhibitors that selectively target GLUT3-expressing tumorigenic HeLa cell hybrids as compared with non-tumorigenic hybrids that express GLUT1 alone. The GSK-3 inhibitors as well as GSK-3β RNAi suppressed GLUT3 expression at the level of transcription, leading to apoptosis. This suppression was associated with NF-κB in a p53-independent manner. Furthermore, GSK-3 inhibitors exhibited a synergistic effect with anticancer agents such as adriamycin and camptothecin in GULT3-overexpressing colon cancer cells, but little effect in non-producing A431 cells. These results suggest a potential use of GSK-3 inhibitors to selectively kill cancer cells that overexpress GLUT3.

Abstract
It is well-known that self-etching primers can be altered. However, the effects from altered primers on the dentin bond durability have yet to be thoroughly identified. In this study, we examined the effects from 5 altered Liquid A primers in different stages of degradation-where 2-hydroxyethylmethacrylate (HEMA) and 10-methacryloyloxydecyl dihydrogen phosphate (MDP), used in Liquid A primers, were altered by the hydrolysis of the methacryloxy ester portion in the HEMA and MDP-on the hybrid layer's quality and dentin bond durability. The hypothesis was that degradation stages of altered Liquid A primers have no effect on the hybrid layer's quality and on dentin bond durability. Bond strengths, obtained after thermo-cycling, were strongly dependent on the degradation stage of the altered Liquid A primer. Alterations of self-etching primers reduced dentin bond durability and decreased the created hybrid layer's quality.

Abstract
As the North Equatorial Current (NEC)-bifurcation is known to be related to El Niño-Southern Oscillation (ENSO) events, the influence of the position of the NEC bifurcation on transport success of the larval Japanese eel Anguilla japonica was investigated. Using a Lagrangian modelling approach, larval transport was simulated and the relative influence of El Niño and La Niña events and the NEC-bifurcation position on the success of particle transport analysed. The number of particles transported from the NEC to the Kuroshio tended to be lowest during El Niño years, and differences between La Niña and regular years were small. The transport success observed in simulations showed some relationships to annual A. japonica glass eel recruitment to Tanegashima Island over 1993 to 2001, but not in 2002. The study shows that particle tracking simulations can be used to improve knowledge of the oceanic migration of A. japonica but further studies are required, including comparisons with the effects on larval survival of fluctuations in temperature and food availability.

Abstract
We report a case of type A aortic dissection with severe atherosclerosis. An 81-year-old man with acute type A aortic dissection was referred to our hospital. Computed tomography revealed DeBakey type II dissection with severe atherosclerosis. Ascending aortic replacement was performed urgently, and an autologous pericardium strip was placed in the lumen to prevent atheroembolization and to reinforce the friable atherosclerotic intima This technique was useful for avoiding cerebral vascular accidents. The patient was discharged on the 24th operative day with no complications.

Abstract
Perforation of colon into the pleural space without diaphragmatic hernia is extremely rare. This report illustrates a case of pneumo-pyothorax caused by perforation of metastatic tumor of the transverse colon of a 67-year-old woman with a history of total gastrectomy and splenectomy for advanced gastric carcinoma 4 years before. The patient was admitted to our hospital presenting with fever and dyspnea, which subsided after a thoracic drainage. Cultures of drained effusion revealed Escherichia coli, Klebsiella and Bacteroides. An emergent laparotomy for treatment of mechanical ileus 2 weeks after her admission disclosed a tumor obstructing the splenic flexure of the transverse colon, and a double-barreled colostomy was made. Pathologic examination of the tumors obtained from colon, mesocolon and the parietal peritoneum revealed poorly differentiated adenocarcinoma that was the same as her primary gastric cancer.

Abstract
The objective of this report is to determine the need for and value of the long-term follow-up study of phenylketonuria (PKU) patients detected by newborn screening (NBS) in Japan. NBS was started in 1977 and the nationwide follow-up study of the identified patients was introduced into the NBS system. Outcome data from the continuous follow-up study showed in 1993 that IQ of PKU patients was inversely correlated with blood phenylalanine levels. Accordingly, in 1995, new treatment guidelines were issued that involved more stringent restriction of phenylalanine levels. Follow-up data confirmed that mean blood phenylalanine levels decreased after the introduction of the new guidelines, which included the recommendation to start dietary treatment within 20 days postpartum. Follow-up data also confirmed that dietary treatment did in fact commence earlier after the guidelines were issued. The need for lifelong dietary treatment is a difficult issue and the number of patients who stop dietary treatment was found to increase gradually with age. At present 60% of PKU patients born between 1977 and 1981 have stopped their dietary restriction of phenylalanine. The data gained from NBS and the long-term follow-up study were found to be valuable for the improvement of blood phenylalanine levels for patients with PKU, indicating the need for parties responsible for NBS and the follow-up study of the identified patients to work cooperatively. Further, the evaluations of the effectiveness of the two initiatives as well as the treatment guidelines issued should be based on outcome data, which depend on the continuation of the follow-up study of patients with PKU.

Abstract
BACKGROUND The impact of enteral nutrition on post-operative recurrence has not been properly examined. AIM To investigate the impact of enteral nutrition using an elemental diet on clinical and endoscopic recurrence after resection for Crohn's disease. METHODS Forty consecutive patients who underwent resection for ileal or ileocolonic Crohn's disease were studied. After operation, 20 patients continuously received enteral nutritional therapy (EN group), and 20 had neither nutritional therapy nor food restriction (non-EN group). In the EN group, enteral formula (Elental) was infused through a nasogastric tube in the night-time, and low fat foods were taken in the daytime. All patients were followed up regularly for 1 year after operation. Ileocolonoscopy was performed at 6 and 12 months after operation. RESULTS One patient (5%) in the EN group and seven (35%) in the non-EN group developed clinical recurrence during 1-year follow-up (P = 0.048). Six months after operation, five patients (25%) in the EN group and eight (40%) in the non-EN group developed endoscopic recurrence (P = 0.50). Twelve months after operation, endoscopic recurrence was observed in six patients (30%) in the EN group and 14 (70%) in the non-EN group (P = 0.027). CONCLUSIONS Our long-term enteral nutritional therapy significantly reduced clinical and endoscopic recurrence after resection for Crohn's disease.

Abstract
BACKGROUND Ciliated cells in gastrectomies from patients dwelling in the Pacific and Atlantic basins have been reported previously. AIM To compare all the results in an attempt to explain the findings. METHODS Sections from 3406 gastrectomies were reviewed: 1966 and 1440 from the Atlantic and Pacific basins, respectively. Ciliated cells and intestinal metaplasia (IM) were recorded; IM was classified into focal or extensive IM. The total number of sections/gastrectomy was noted. RESULTS In the Atlantic basin, 5% of specimens had ciliated metaplasia (CM); it was more frequent in intestinal carcinoma (IC; 9%) than diffuse carcinoma (DC; 3%) or miscellaneous gastric diseases (MGD; 3%). In the Pacific basin, the frequency of specimens with CM was 29%: it was more frequent in IC (43%) than in DC (16%) or MGD (10%). The difference between the frequency of CM in specimens with IC or with DC/MGD in the Atlantic and the Pacific basins was significant (p < or = 0.05). The presence of CM was influenced by age and the extent of IM in both basins, but not by sex or the number of sections investigated. CONCLUSIONS CM-apparently an independent microscopic marker-was significantly higher in the Pacific than in the Atlantic basin. Environmental carcinogens involved in the evolution of IM and IC seem to be implicated in gastric ciliogenesis. Carcinogens that differ in nature and/or in strength in both basins might activate the latent natural genes encoding ciliated processes in gastric cells in patients subsequently developing gastric carcinoma, more notably of intestinal type.

Abstract
Cancer cells in solid tumors are challenged by various microenvironmental stresses, including hypoxia, and cancer cells in hypoxic regions are resistant to current cancer therapies. To investigate the mechanism of resistance to hypoxia in cancer cells, we examined mouse Lewis lung carcinoma (LLC) cells, which died due to necrosis at high density under hypoxic but not under normoxic conditions. Levels of mammalian target of rapamycin (mTOR), a central regulator of cellular energy, are reported to be suppressed in hypoxia. We found that phosphorylation of two molecules downstream to it, ribosomal p70 S6 kinase (S6K) and ribosomal protein S6, was markedly suppressed by hypoxia. Overexpression of the active form of S6K increased the sensitivity of LLC cells to hypoxia. On the other hand, inhibition of PI3K or mTOR dramatically reduced hypoxia-induced cell death under hypoxic conditions. Under hypoxic conditions, blockade of the PI3K or mTOR pathway increased levels of intracellular ATP and delayed decreases in pH and glucose level in culture medium, without affecting the cell cycle.

Abstract
A simple surgical technique that facilitates circular-stapled Billroth I gastroduodenostomy in laparoscopic distal gastrectomy is described. After standard laparoscopic mobilization of the distal stomach, a small duodenotomy is made just distal to the pyloric ring. The anvil of a circular-stapling device, secured with a Vicryl suture, is introduced via the duodenotomy. The Vicryl suture is advanced anteriorly so that a center rod penetrates the anterior duodenal wall. The duodenum is staple-transected at this point, and the center rod is wrapped with the stapled duodenal stump by approximation of both edges using a suturing device. The circular-stapled gastroduodenostomy then is completed in a standard fashion. The authors have used this technique for three patients, and their early outcomes are promising.

Abstract
A maxillofacial simulator can support education and training. In the present study, cutting, separation, and quantitative rearrangement of bone during orthognathic surgery were simulated by means of a haptic device with virtual tactile perception. Computed tomographic (CT) images of two patients with severe jaw deformity, one women and one man, were input into the device. In the woman, Le Fort I osteotomy of the maxilla and sagittal splitting ramus osteotomy of the mandible were initially simulated. During surgery with the haptic device, separation and rearrangement of the maxilla and the ramus of the mandible were initially processed. However, there was discrepancy and overlapping of the ramus with the mandible. Intraoral vertical osteotomy of the right ramus was then performed, with satisfactory results and less discrepancy and interference. The simulation was referred to at surgery, and satisfactory surgical assistance was postoperatively confirmed on CT images. The male patient had severe jaw deformity due to unequal growth between the ramuses, resulting in anterior crossbite. Sagittal splitting ramus osteotomy with rotation of the mandible was successfully simulated. Because of its versatility and functions, the present device was found to be useful for simulating various procedures for orthognathic surgery and thereby three-dimensionally determine surgical movements.

Fabry Disease (alpha-galactosidase A deficiency) is an X-linked hereditary disorder leading to the pathological accumulation of globotriaosylceramide (GL-3) in lysosomes, particularly in the vascular endothelium of the kidney, heart and brain. We report the results of an open-label phase 2 study that was undertaken to evaluate whether ethnic differences exist that would affect agalsidase beta (Fabrazyme) treatment of Fabry patients in the Japanese population, relative to safety and efficacy. The study design mirrored the design of the completed phase 3 clinical trial that led to approval of the product agalsidase beta. The 13 Japanese, male Fabry patients enrolled in the study received the enzyme replacement therapy over a period of 20 weeks as biweekly infusions. All selected efficacy end points showed improvements that were comparable with findings from the phase 3 study. These improvements included reductions of GL-3 accumulation in both kidney and skin capillary endothelial cells to (near) normal levels (92% of patients). Kidney and plasma GL-3 levels decreased by 51.9% and 100%, respectively, by ELISA. Renal function remained normal. Fabry-associated pain, and quality of life, showed improvement over baseline in multiple categories. Related adverse events were mild or moderate in intensity and mostly infusion-associated (fever and rigors). As expected, IgG antibody formation was observed in 85% of the patients, but had no effect on treatment response. These results suggest that treatment with agalsidase beta is safe and effective in Japanese patients with Fabry disease. With regard to safety and efficacy, no differences were observed as compared to the caucasian population.

Abstract
AIM It is still controversial whether the existence of a contralateral stenosis is a risk factor during carotid endarterectomy (CEA). We used a near infrared spectroscopy (NIRS) monitoring system during CEA to evaluate the hemodynamic effect of contralateral stenosis during cross clamping of the carotid arteries. METHODS We monitored 34 consecutive cases of CEA, using NIRS. Tissue oxygen index (TOI), as a parameter of oxygenation, and total hemoglobin index (THI), as a parameter of blood volume, were measured during cross-clamping the carotid arteries. We evaluated the relationship between these results and the pre- and intraoperative characteristics including the existence of a contralateral stenosis and the results of single-photon emission computed tomography (SPECT). RESULTS Bilateral TOI and THI correlated well with the severity of the stenosis of the contralateral internal carotid artery, and ipsilateral THI correlated with the cerebrovascular reserve measured by SPECT. CONCLUSIONS A contralateral stenosis is a risk factor for CEA from the hemodynamical point of view, and extreme care should be taken when performing CEA in patients with bilateral stenoses.

Abstract
AIM To assess safety and clinical efficacy of granulocyte and monocyte adsorptive apheresis for distal ulcerative colitis. METHODS Granulocyte and monocyte adsorptive apheresis therapy (five aphereses for 5 consecutive weeks) was performed for 30 consecutive patients with active distal ulcerative colitis. Patient compliance, adverse effects and clinical symptoms were regularly assessed. RESULTS Adverse effects were noted during nine (6%) apheresis sessions in eight patients; slight headache five, transient abdominal pain with tenesmus two, fever (38 degrees C) one and mild liver dysfunction one. None of these adverse effects was serious and all patients could complete five aphereses. Clinical symptoms (stool frequency and consistency, rectal bleeding, tenesmus and mucus in stools) significantly improved after the third apheresis. Clinical remission (normal stool frequency and no rectal bleeding) was achieved in 21 patients (70%) after five aphereses. The median Disease Activity Index score significantly decreased; from 6 [interquartile range (IQR): 4-7] to 2 (IQR: 1-3) (P < 0.0001). CONCLUSION In the treatment of active distal ulcerative colitis, granulocyte and monocyte adsorptive apheresis is safe and well-tolerated. Granulocyte and monocyte adsorptive apheresis had a beneficial effect on clinical remission and symptoms. However, randomized-controlled trials would be necessary to assess a definite efficacy of granulocyte and monocyte adsorptive apheresis.
