Abstract
BACKGROUND Recently, two molecular subtypes of pancreatic ductal adenocarcinoma (PDAC) have been proposed: the "Classical" and "Basal-like" subtypes, with the former showing better clinical outcomes than the latter. However, the "molecular" classification has not been applied in real-world clinical practice. This study aimed to establish patient-derived organoids (PDOs) for PDAC and evaluate their application in subtype classification and clinical outcome prediction. METHODS We utilized tumor samples acquired through endoscopic ultrasound-guided fine-needle biopsy and established a PDO library for subsequent use in morphological assessments, RNA-seq analyses, and in vitro drug response assays. We also conducted a prospective clinical study to evaluate whether analysis using PDOs can predict treatment response and prognosis. RESULTS PDOs of PDAC were established at a high efficiency (> 70%) with at least 100,000 live cells. Morphologically, PDOs were classified as gland-like structures (GL type) and densely proliferating inside (DP type) less than 2 weeks after tissue sampling. RNA-seq analysis revealed that the "morphological" subtype (GL vs. DP) corresponded to the "molecular" subtype ("Classical" vs. "Basal-like"). The "morphological" classification predicted the clinical treatment response and prognosis; the median overall survival of patients with GL type was significantly longer than that with DP type (P < 0.005). The GL type showed a better response to gemcitabine than the DP type in vitro, whereas the drug response of the DP type was improved by the combination of ERK inhibitor and chloroquine. CONCLUSIONS PDAC PDOs help in subtype determination and clinical outcome prediction, thereby facilitating the bench-to-bedside precision medicine for PDAC.

Abstract
BACKGROUND Streptozocin has been used to treat neuroendocrine tumors in Europe and the USA; however, its actual status in Japan has not been fully clarified owing to the rarity of this disease and the relatively recent approval of streptozocin in Japan. METHODS We retrospectively analyzed 53 patients with gastroenteropancreatic neuroendocrine tumors who were treated with streptozocin-based chemotherapy at two Japanese hospitals between January 2004 and June 2023. RESULTS The overall response and disease control rates were 27.7 and 74.5%, respectively, and the median progression-free survival and overall survival were 7.1 and 20.3 months, respectively. Performance status ≥1 showed a significant negative correlation with progression-free survival, and performance status ≥1 and liver tumor burden ≥25% showed a significant negative correlation with overall survival. No significant differences were observed in the treatment response between pancreatic and gastrointestinal neuroendocrine tumors. No treatment-related serious adverse events were observed; however, 87.7% of patients expressed a decrease in the estimated glomerular filtration rate, which negatively correlated with the duration of streptozocin treatment (r = 0.43, P = 0.0020). In the streptozocin re-administration group (n = 5), no differences were found in efficacy between the initial and second streptozocin treatments. CONCLUSIONS Although streptozocin is a safe, streptozocin-induced renal dysfunction is a dilemma in streptozocin responders. Streptozocin may benefit patients with gastroenteropancreatic neuroendocrine tumors, especially those with a good performance status; however, in some cases, planned streptozocin withdrawal or switching to other drugs should be considered.

Abstract
BACKGROUND Recently, endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) procedures have been gradually established; nonetheless, some adverse events (AEs) have been reported. Dilation procedures using a non-cautery or cautery device increase the incidence of AEs in EUS-HGS. AIMS We evaluated EUS-HGS procedures without dilation and the factors associated with dilation. METHODS We enrolled 79 patients who underwent EUS-HGS between July 2015 and March 2021 at two centers, 72 of whom had technical success (72/79, 91%). During the EUS-HGS procedures, we defined patients without dilation procedures as the dilation (-) group. We divided the patients into two groups: the dilation (+) (35 patients) and dilation (-) (37 patients) groups. We performed a propensity score matching analysis to adjust for confounding bias between the two groups. Multivariable logistic regression analysis was conducted to identify factors associated with dilation. RESULTS There was no difference in clinical success rate between the dilation (+) and dilation (-) groups (91% vs. 95%, P = 0.545). The AE rate (P = 0.013) and long procedure time (P = 0.017) were significantly higher in the dilation (+) group than in the dilation (-) group before and after propensity score matching. Factors associated with dilation were plastic stent placement (odds ratio [OR], 6.96; 95% confidence interval [CI], 1.68-28.7; P = 0.007) and puncture angle of ≤ 90° (OR, 44.6; 95% CI, 5.1-390; P < 0.001). CONCLUSIONS A dilation procedure in EUS-HGS may not always be necessary. However, patients with an angle of ≤ 90° between the needle and intrahepatic biliary tract or plastic stent deployment require dilation procedures.

Abstract
Purpose
The distribution of tissue infiltrating lymphocytes has been shown to affect the prognosis of patients with pancreatic cancer in some previous studies. However, the role of peripheral lymphocytes in pancreatic cancer remains debated. The purpose of this study was to analyze the peripheral subtypes of T lymphocytes, and establish their association with the prognosis of patients with pancreatic cancer.
Methods
Blood and tissue samples were collected from patients with metastatic pancreatic cancer (n = 54), resectable pancreatic cancer (n = 12), and benign pancreatic cysts (n = 52) between April 2019 and January 2022 and analyzed.
Results
Patients with metastatic pancreatic cancer had a larger proportion of both tumor-suppressive and tumor-promoting cells than those with benign pancreatic cysts. In addition, the proportion of peripheral CD4+ T cells positively correlated with the survival of patients with metastatic pancreatic cancer, and the proportion of peripheral CD8+CD122+ T cells was associated with early mortality (< 90 days). After chemotherapy, CD8+CD122+ T cells decreased in patients who had a partial response or stable disease. Moreover, by analyzing resected specimens, we first proved that the existence of CD8+CD122+ T cells in a tumor microenvironment (TME) depends on their proportion in peripheral blood.
Conclusion
Circulating CD8+CD122+ T cells can be a prognostic indicator in patients with pancreatic cancer.

Abstract
BACKGROUND/AIMS Patients with acute cholecystitis (AC) after metallic stent (MS) placement for malignant biliary obstruction (MBO) have a high surgical risk. We performed percutaneous transhepatic gallbladder aspiration (PTGBA) as the first treatment for AC. We aimed to identify the risk factors for AC after MS placement and the poor response factors of PTGBA. METHODS We enrolled 401 patients who underwent MS placement for MBO between April 2011 and March 2020. The incidence of AC was 10.7%. Of these 43 patients, 37 underwent PTGBA as the first treatment. The patients' responses to PTGBA were divided into good and poor response groups. RESULTS There were 20 patients in good response group and 17 patients in poor response group. Risk factors for cholecystitis after MS placement included cystic duct obstruction (p<0.001) and covered MS (p<0.001). Cystic duct obstruction (p=0.003) and uncovered MS (p=0.011) demonstrated significantly poor responses to PTGBA. Cystic duct obstruction is a risk factor for cholecystitis and poor response factor for PTGBA, whereas covered MS is a risk factor for cholecystitis and an uncovered MS is a poor response factor of PTGBA for cholecystitis. CONCLUSION The onset and poor response factors of AC after MS placement were different between covered and uncovered MS. PTGBA can be a viable option for AC after MS placement, especially in patients with covered MS.

Abstract
VIPomas are generally rare functioning pancreatic neuroendocrine tumors (PanNETs) that cause watery diarrhea, hypokalemia, and achlorhydria. Due to their extreme rarity, the clinicopathological features and outcomes of VIPomas have not been well reported. This study aimed to determine the diagnostic and therapeutic characteristics and prognosis of VIPomas and to compare them with other PanNETs at a Japanese reference hospital. Medical records of 293 patients with PanNETs were collected. Patient and tumor characteristics and outcomes were retrospectively reviewed. This cohort had only 1.4% (four patients) of patients with VIPomas, and three of these patients changed from non-functioning (NF-) PanNETs during their disease course. Recurrences of hormonal symptoms were observed in all patients despite the initial controls, and all of them died from their disease, more specifically mainly from hormonal symptoms. Compared to the other PanNETs, VIPomas were all located at the pancreatic tail, were larger, and had a higher Ki-67 index and more metastasis. The median survival time was significantly shorter for patients with VIPoma than for those with NF-PanNET (5.9 vs. 26.7 years, p < 0.0001), insulinoma (21.8 years, p < 0.0001), and gastrinoma (12.3 years, p = 0.0325). This study presents the possibility of shifting from non-symptomatic to symptomatic VIPomas as they grow or of transforming from NF-PanNETs to VIPomas. VIPomas should be considered in patients with relatively large NF-PanNETs, especially those located in the pancreatic tail, when diarrhea is continuously observed. As hormonal symptoms are an important cause of death in VIPomas, long-term symptomatic control, which is relatively difficult, is of great significance.

Abstract
Endoscopic duodenal stent (DS) placement for malignant gastric outlet obstruction (GOO) is rapidly increasing in clinical practice; however, the most suitable patient candidates for DS placement have not been determined. One hundred and thirty-five patients with GOO who underwent DS placement in three Japanese referral centers between January 2010 and October 2019 were retrospectively evaluated. Overall survival (OS) after DS placement, technical/clinical success rates, adverse events, and predictive factors affecting OS after DS placement were also analyzed. The median OS after DS placement of all patients was 81 (7–901) days. Technical and clinical success rates were 99.3% and 83.7%, respectively. The GOO Scoring System score significantly increased before and after DS placement (0.9 vs. 2.7, P < 0.001). The procedure-related complication rate was 6.0%. All 19 patients (14.1%) with stent occlusion underwent endoscopic re-intervention successfully. Multivariate analyses revealed chemotherapy after DS placement (P = 0.01), stricture site in D3 (distal part of the papilla) (P = 0.01), and a Glasgow Prognostic Score (GPS) of 0–1 before duodenal stent placement (P < 0.001) were factors significantly associated with prolonged OS. In conclusion, patients with a GPS of 0–1 and D3 stricture who are tolerant of chemotherapy are suitable candidates for DS placement.

Abstract
BACKGROUND/AIMS Recently neoadjuvant chemotherapy (NAC) for pancreatic cancer has been shown to be superior to upfront surgery, but it remains a matter of debate for resectable cases. In clinical practice, some resectable cases may become unresectable after NAC. This study aimed to reveal the outcomes after NAC and to clarify the characteristics of unresected cases. METHODS The medical records of 142 patients who underwent NAC between 2016 and 2020 were retrospectively reviewed. Patient characteristics, effectiveness of NAC, and outcomes were compared between the surgical group and non-surgical group (NSG). Furthermore, the risk of recurrence limited to in the patients who received NAC with gemcitabine plus nab-paclitaxel, which were mostly administered in this cohort, following R0/R1 resection was assessed. RESULTS The overall and R0 resection rates after NAC were 89.1% and 79.7%, respectively. The neutrophil to lymphocyte ratio (NLR) > 2.78 (p = 0.0120) and anatomical borderline resectable pancreatic cancer (p = 0.0044) revealed a statistically significantly correlation with the NSG. On the other hand, NAC week < 8 (p = 0.0285), radiological response, stable disease or progression disease (p = 0.0212), and pathological stage > IIA (P = 0.0003) were significantly associated with recurrence. The tumor response rate was approximately 26.1%, and three patients with ≥ 30% reduction of primary tumor lost excision opportunities because of metastasis, interstitial pneumonia, and vascular invasion. CONCLUSIONS This study shows incomplete tumor shrinkage benefits, but pre-NAC NLR is a predictive factor for predicting operability after NAC. The NLR can be easily calculated by normal blood test, and can be considered as a suitable marker of operability.

Abstract
A 54-year-old man with pancreatic head tumor had undergone pancreaticoduodenectomy and was diagnosed with pancreatic neuroendocrine tumor (P-NET) associated with sporadic multiple endocrine neoplasm type 1. Five years after the resection, P-NET recurred and liver metastases were observed. He was treated with a somatostatin analog. Eleven years after the resection, computed tomography revealed a new pancreatic hypodense and hypovascular mass adjacent to the P-NET that was diagnosed as pancreatic adenocarcinoma via endoscopic ultrasound-guided fine-needle aspiration. He underwent a total remnant pancreatectomy. Pathological examination showed that the lesion was constituted by a pancreatic ductal adenocarcinoma (PDAC) and a neuroendocrine tumor. Additionally, the invasive ductal carcinoma collided with the neuroendocrine tumor. Both PDAC and P-NET cells were observed in the collision area. We could observe the onset of PDAC during the treatment of P-NET. Moreover, we are the first to report the case of a collision of pancreatic endocrine and exocrine tumors diagnosed preoperatively.

Abstract
Background Gastroenteric neuroendocrine carcinomas (NECs) account for 6.2% of gastroenteric neuroendocrine tumors (NETs), and only 1% or less of gastroenteric NETs occur in the ampulla of Vater (AoV). Clinical features of NEC of the AoV remain obscure. Case presentation A 65-year-old man visited a general practitioner because of jaundice, and an abdominal contrast-enhanced computed tomography scan revealed a tumor of 11 mm in diameter, which was enhanced in the arterial phase at the duodenal papilla, with dilation of the upstream bile duct. Gastrointestinal scope revealed an unexposed tumor of the AoV. Based on a biopsy of the site, a moderately differentiated tubular adenocarcinoma was suspected, and pancreatoduodenectomy was performed. Histopathological examination revealed dysplasia and highly proliferative small tumor cells, with solid and nodular formation at the AoV. Histological analysis showed a high mitotic count, and immunohistochemical staining revealed a Ki-67 index of 40–50% and cells positive for synaptophysin, chromogranin A, and p53. Small cell-type NEC was finally diagnosed. Four months post pancreatoduodenectomy, multiple liver metastases developed, and systemic chemotherapy was administered. Salvage liver resection for liver metastases was performed 14 months after the pancreatoduodenectomy. Unfortunately, multiple liver metastases developed 2 months after liver resection, and the patient died 18 months after the pancreatoduodenectomy. Conclusions Neuroendocrine carcinoma originating from the bile duct is very rare; therefore, in this article, we provide a review of the literature and a case report.

Abstract
Background The purpose of this study was to assess the cortical-level sensory differences between natural teeth with a periodontal membrane and dental implants.
Material and Methods We used functional near-infrared spectroscopy (fNIRS) to measure brain activity in the cerebral cortex of 12 patients who had both natural teeth and dental implants in the lower molar region. Painless vibratory tactile stimulation was performed on both the natural teeth and the dental implants.
Results Activation was seen in the somatosensory cortex during stimulation of both natural teeth and dental implants. A comparison of cortical activation showed no significant differences between natural teeth and dental implants.
Conclusions These results indicate the possible existence of sensory input to the cerebral cortex via dental implants as well as natural teeth, and thus suggest that may not only the periodontal membrane be involved in the signaling pathway. The data from this experiment may help us for understanding the neural mechanisms underlying natural teeth and dental implants. Key words:fNIRS, natural teeth, implants, brain activity, somatosensory cortex.

Abstract
Obinutuzumab is a novel glycoengineered, type-II anti-CD20 monoclonal antibody that was recently developed to treat follicular lymphoma (FL), the most prevalent subtype of indolent B-cell lymphoma. Several intensely hypermetabolic lesions (SUVmax: 40) were identified in the post-mediastinal and paraaortic lymph nodes by 18F-FDG-PET maximum-intensity projection images of a 58-year-old man who presented with systemic lymphadenopathy. A biopsy at the time of laparotomy definitively diagnosed grade 1 FL. The patient was given the recommended standard premedication, comprising acetaminophen (1000 mg), diphenhydramine (50 mg), and dexamethasone (20 mg), and then started on six cycles of obinutuzumab plus cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP). However, the patient developed severe hypotension and dyspnea about 15 min after starting obinutuzumab. It was difficult to differentiate between a possible allergic reaction and infusion-related reaction. A pleural effusion was drained to reduce the tumor burden, after which a single course of CHOP was started. Rituximab (R) was added 10 days later without incident, and the patient completed six cycles of the R-CHOP therapy without adverse events. We conclude that R-CHOP was safe for administration to patients who react to infused obinutuzumab. Such patients should be carefully monitored during R infusion, given the risk of cross-reactivity.

Abstract
OBJECTIVE Autoimmune pancreatitis is an autoimmune disorder accompanied by clinicopathological manifestations that have been established as immunoglobulin (IgG)4-related diseases (IgG4-RD). Other IgG4-RD are often involved with autoimmune pancreatitis. They sometimes relapse despite a favorable response to steroid therapy. This study aimed to clarify the patterns and risk factors for extrapancreatic relapse. METHODS We reviewed the data of 115 patients diagnosed with definite autoimmune pancreatitis type 1 and followed up for > 1 year. We analyzed two items: the timing and pattern of extrapancreatic relapse, and risk factors for relapse with three common manifestations: IgG4-related sclerosing cholangitis (SC), IgG4-related dacryoadenitis and sialadenitis (DS), and IgG4-related retroperitoneal fibrosis (RF). RESULTS Remission was achieved in all patients, except one. The extrapancreatic relapse rates were 11.0%, 19.7%, and 40% within 3, 5, and 10 years, respectively. Of 26 patients with extrapancreatic relapse, nine (34.6%) relapsed with a new IgG4-RD. Based on multivariate analysis, the interval between symptom onset and steroid initiation, and the presence of RF at onset were significant risk factors for relapse with SC and RF, respectively. CONCLUSIONS Our results indicate that they may be various extrapancreatic relapse patterns especially in autoimmune pancreatitis with other organ involvement. Patients with a delayed initiation of steroids or RF at onset should be carefully followed up as high-risk groups for SC and RF relapse.

Abstract
BACKGROUND AND PURPOSE Despite the development of neuroimaging, identification of focal cortical dysplasia remains challenging. The purpose of this study was to show the longitudinal changes of MR imaging and FDG-PET in patients with West syndrome and subtle focal cortical dysplasia. MATERIALS AND METHODS Among 52 consecutive patients with West syndrome, 4 were diagnosed with subtle focal cortical dysplasia on 3T MR imaging. MR imaging and PET findings were evaluated longitudinally at onset and at 12 and 24 months of age. RESULTS At the onset of West syndrome, MR imaging demonstrated focal signal abnormalities of the subcortical white matter in 2 patients. In the other 2 patients, focal subcortical high-intensity signals became visible on follow-up T2WI as myelination progressed. PET at onset showed focal cortical hypometabolism in 3 patients, with 1 of these patients also having focal hypermetabolism and 1 having normal findings. On PET at 24 months, hypometabolism persisted in 2 patients and disappeared in 1, and hypermetabolism disappeared in 1. In 1 patient with normal MR imaging and PET findings at onset, focal hyperintensity and hypometabolism first appeared at 24 months of age. The findings on MR imaging and PET in these patients evolved differently with brain maturation and the clinical course. CONCLUSIONS Subtle focal cortical dysplasia can be undetectable on MR imaging at the onset of West syndrome and is not always accompanied by hypometabolism or hypermetabolism on PET. Longitudinal MR imaging and PET studies may be useful for detecting such lesions. Even in West syndrome with a congenital structural abnormality, PET findings evolve differently with brain maturation and the clinical condition.

Abstract
The occurrence of diarrhea at the beginning of enteral nutrition complicates the continuation of enteral nutrition. Recently, studies in Japan indicated that diarrhea could be improved by changing the enteral formula to one that is emulsified with egg yolk lecithin. In this study, we administered the enteral formula K-2S plus, which is emulsified with egg yolk lecithin, to 15 patients (four men and 11 women; mean age, 79.9 ± 2.0 years) after they had undergone a percutaneous endoscopic gastrostomy (PEG) to prevent the occurrence of diarrhea related to enteral nutrition. Two days after the PEG, the patients would receive 200 mL K-2S plus intermittently three times daily; thereafter, the amount of K-2S plus was increased according to the patient’s condition. The administration rate was scheduled as 200 mL/h when 200 mL were administered at one time. For ≥ 300 mL, the scheduled administration rate was 300 mL/h. When we administered K-2S plus at the beginning of enteral nutrition after the PEG, the dose of the enteral formula could be increased without any occurrence of diarrhea or vomiting. Five patients had received intravenous nutrition before the PEG; thus, we were concerned about diarrhea in these patients. In conclusion, an enteral formula emulsified with egg yolk lecithin may be safely used at the time of enteral nutrition initiation without causing diarrhea.

Abstract
For elderly people who are difficult to operate, percutaneous transhepatic gallbladder drainage (PTGBD) is conducted instead. In PTGBD, the bile is drained externally and impaired absorption of fat is a concern. Egg yolk lecithin, which is a fat emulsifier, is not easily broken in emulsion even under a low-pH condition, and the emulsified state is stable. Even in bile duct ligation rats, the emulsifier in egg yolk lecithin emulsion is reported to be superior to lipid absorption using other emulsifiers. Emulsification with egg yolk lecithin may possibly contribute to improvement of nutrition during biliary excretion disorders such as external drainage. We report a case of good progress with enteral nutrition with egg yolk lecithin-mixed liquid diet after PTGBD for acute cholecystitis. The patient was an 80-year-old man with a history of myocardial infarction and dementia. He was diagnosed with calculous cholecystitis, and conservative treatment was started. His cholecystitis was exacerbated, and PTGBD was performed on day 12 of the disease. On imaging, the lower extremities of the duodenum were edematous because of the spread of inflammation. Glutamine preparation alone was administered after resuming fasting. A liquid diet containing egg yolk lecithin, 200 ml of K-LEC (1 kcal/ml), was started from day 23, and was administered three times daily. Liquid diet dose was increased to 1,200 kcal/day with added dietary fiber on day 29. The patient's overall condition improved, and transthyretin level and body weight increased. Thereafter, after swallowing training, the patient was switched to oral meal intake from day 37.

Abstract
To investigate the role of p53 abnormalities in predicting the survival of patients with non-small cell lung cancer (NSCLC), polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and immunohistochemical analyses were performed on 74 and 67 tumor samples, respectively, from patients with pathological stage I-IIIa NSCLC. An abnormally migrating SSCP band was observed in 21 of 74 (28%) tumor specimens. DNA sequence analysis revealed 23 intragenic mutations including 3 small deletions and 20 point mutations. Immunohistochemical analysis using the DO-7 monoclonal antibody showed abnormal expression of p53 in 27 of 67 (40%) patients. The concordance rate between immunohistochemical and PCRSSCP analyses was 73% (49/67) in this study. Univariate and multivariate analyses demonstrated that abnormal expression of p53 may be associated with prolonged survival (p=0.0997 and 0.0099, respectively). In contrast, no relationship was observed between p53 mutation and overall survival (0.6968). These results suggest that p53 status and the survival outcome changes between immunohistochemical and mutational analyses in stage I-IIIa NSCLC.

Abstract
AIMS The aim of study was to evaluate the safety and efficacy of insulin detemir as a basal insulin switching from neutral protamine Hagedorn insulin (NPH) and insulin glargine in patients with diabetes on an intensive insulin therapy regimen. METHODS This 6-month multicentre, prospective, treat-to-target [glycosylated haemoglobin (HbA(1c) ) less than 6.5%] trial included 92 people with diabetes (61 type 1, 29 type 2 and two unknown diabetes types). Detemir was administered first with fixed dose and injection times and then adapted to optimal dose after 3 months. RESULTS Mean HbA(1c) (%) of all the subjects at months 4 to 6 of the study was improved compared with month 0 (7.34 ± 0.87, 7.28 ± 0.88, 7.25 ± 0.93 vs. 7.55 ± 1.18; p < 0.05 paired t-test). However, significant improvement was seen only among the patients who had previously used NPH as a basal insulin. Twice-daily injection of basal insulin increased among people in the type 1 previously injected insulin glargine. Total insulin dose increased in the type 1 glargine group. The mean body weight change in the highest quartile body mass index (BMI) group was from 70.7 to 69.3 kg over the 6 months. Quality of life (QoL) relating to the patients' glycaemic control tended to improve without a change in frequency of hypoglycaemia. CONCLUSIONS The results suggest that insulin detemir has a greater effect on glycaemic control in subjects with poor glycaemic control using NPH; can reduce or maintain body weight in obese patients; and obtains perceptive stability for patients with unstable glycaemic control.

Abstract
PURPOSE Human multicentric osteosarcoma (HMOS) is a rare, aggressive variant of osteosarcoma, and its etiology is not clear. We used newly established HMOS cells, which were derived from primary (HMOS-A) and secondary (HMOS-P) lesions, respectively, to perform a basic study analyzing the cellular biology and gene expression of HMOS. METHODS We performed a cell growth assay, an invasion assay, DNA microarray analysis, quantitative real-time RT-PCR (Qrt-PCR), and a telomerase assay and compared the results between HMOS-A, HMOS-P, and human osteosarcoma (HOS) cell lines (MNNG-HOS and Saos-2). RESULTS The cell biological analysis revealed that HMOS-A and HMOS-P had similar characteristics to Saos-2, and the invasion assay showed that they had similar characteristics to MNNG-HOS. The DNA microarray study showed that the gene expression profiles of HMOS-A and HMOS-P were similar to that of MNNG-HOS, but the overexpression of MMP-2, MMP-9, and MT1-MMP was observed in HMOS-A and HMOS-P, which was correlated with the invasiveness of the extracellular matrix, and collagen type-4 (COL-4) and VEGF were also detected. HMOS-A and HMOS-P showed low telomerase activity similar to Saos-2, which are known to be telomerase negative, but a similar telomere length and telomerase protein to MNNG-HOS. CONCLUSIONS HMOS-A and HMOS-P demonstrated strong invasive ability, and their gene expression profiles correlated with the invasiveness of the extracellular matrix. Their telomerase activity was low, but they did not shown the typical features of alternative lengthening of telomeres (ALT). HMOS-A and HMOS-P are useful models for further study of various biological aspects and therapeutic manipulation of HMOS.

Abstract
Two patients with dermatomyositis complicated with Sjögren's syndrome (SjS), are reported. Both patients exhibited sensory-dominant polyneuropathy, compatible with neurologic involvement in SjS. Vascular endothelial growth factor (VEGF) levels were increased in their plasma. Histological examination demonstrated vasculitic changes in biopsied specimens of muscle and salivary glands from the patients, and VEGF was overexpressed in the vasculitic lesions. These findings suggest that VEGF overexpression was associated with the development of vasculopathy in skeletal muscle and salivary glands and possibly in the peripheral nervous system.

Abstract
1. Cytochrome p450 (p450) 2E1 is a hepatic enzyme of importance for the metabolism of xenobiotics such as drugs and environmental toxicants. Genetic polymorphisms of CYP2E1 in 5'-flanking and coding regions have been found previously in Caucasian and Chinese populations. 2. In order to investigate the effects of amino acid substitutions on the function of CYP2E1, the enzymes of all known CYP2E1 variants in the coding region (CYP2E1.2, CYP2E1.3 and CYP2E1.4) with Arg76His, Val389Ile and Val179Ile substitutions, respectively, as well as the wild-type CYP2E1 (CYP2E1.1) were expressed in COS-1 cells, and their chlorzoxazone 6-hydroxylation and 4-nitrophenol 2-hydroxylation activities were determined. 3. The protein level of CYP2E1.2 was reduced to 29% compared with that of CYP2E1.1. The profiles of the level of activity relative to CYP2E1.1 for chlorzoxazone 6-hydroxylation (300 microM substrate) and 4-nitrophenol 2-hydroxylation (150 microM substrate) were very similar. 4. Although the K(m) values were not significantly different among wild-type and variant CYP2E1s in any oxidation metabolism, the V(max) and V(max)/K(m) of CYP2E1.2 on the basis of the CYP2E1 protein level were 2.7-3.0-fold higher than those of CYP2E1.1. In contrast, the levels of CYP2E1 protein and catalytic activity of CYP2E1.3 and CYP2E1.4 were not affected by the corresponding amino acid substitutions. 5. The findings suggest that Arg76 is closely associated with the function of CYP2E1, and that the genetic polymorphism of CYP2E1 is one cause of interindividual differences in the toxicity of xenobiotics.

Abstract
The development and use of antibiotics for the chemotherapy of bacterial infections was one of the most remarkable accomplishments in medicine of the 20th. However, antibiotic-resistant bacteria were found in clinical isolates soon after the introduction of the earliest antimicrobial agents into the market. Significant increases in prevalence of resistance to antimicrobial agents have been observed in common pathogens of humans in the worldwide and problems of resistance are still presently serious among the immunocompromised host. The most important of these organisms are methicillin-resistant Staphylococcus aureus penicillin-resistant Streptococcus pneumoniae, vancomycin-resistant Enterococcus, and certain gram-negative bacilli due to extended-spectrum beta-lactamase production. These antibiotic resistances have made antimicrobial therapy of many infections extremely difficult or virtually impossible in some instances. In this article, we reviewed the history of antibiotic-resistance and discussed on the future.

Abstract
The incidence of Enterococcal nosocomial infection has increased since 1980s. Most Enterococci are intrinsically resistant to many kinds of antibiotics, therefore, therapeutic drugs for enterococal infectious disease are limited to a few antibiotics such as ampicillin, gentamicin and vancomycin. However, since the first report of penicillinase producing E. faecalis in 1983, ampicillin-resistant strains have been increasing, furthermore, these strains often associated with high-level resistance to aminoglycosides. The yearly usage of vancomycin increased because vancomycin was only effective drug against such resistant strains and worldwide spread of multidrug-resistant MRSA which vancomycin is only effective. However, High-level vancomycin-resistance strains of E. faecium were first isolated in England in 1986. In 1990s, VRE have been spreading all over the world, especially, the emergency of multidrug-resistant strains, which are resistant to high concentrations of ampicillin or gentamicin or to vancomycin in USA, brought serious therapeutic dilemmas. This review focuses on the background in emergence of VRE, the relation with use of avoparcin, is used for growth promotion in farm animals, the mechanism of resistance, and the prevention of the spread of vancomycin resistance.

Abstract
Precursors of NAD model compounds 1c and 3a,b were successfully resolved into their atropisomers with respect to carbamoyl rotation. Atropisomers of quinoline derivatives are much more stable than pyridine derivatives as determined by cyclic voltammetry and X-ray crystallography. The 1,4-reduction of NAD model compound 4 was successfully achieved, affording novel NADH model compound 5. The rotational properties of the side chain of 5 were investigated by means of dynamic NMR. The rotational rate and syn/anti ratio, which indicate the orientation between carbonyl oxygen and hydrogen at the 4-position, are significantly affected by addition of magnesium ion. In the rotational transition state, the double-bond character of the C(carbonyl)-N(amide) bond is disrupted judging from the activation parameters. The oxidation of chiral 5 with p-benzoquinone in the presence of magnesium ion catalyst gave predominantly one enantiomer of 4. On the other hand, oxidation of 5 with p-chloranil (tetrachloro-p-benzoquinone) in the absence of magnesium ions affords the opposite enantiomer of 4 as the major product. The product enantiomer ratio is parallel to the syn/anti ratio in the starting material, indicating the importance of ground state conformation to stereochemistry of the reaction.
