Abstract
Blastomas, characterized by a mixture of mesenchymal, epithelial, and undifferentiated blastematous components, are rare malignant neoplasms originating from precursor blast cells. This review focuses on digestive system blastomas in adult patients, including gastroblastoma, hepatoblastoma, and pancreatoblastoma. Gastroblastoma is a biphasic, epitheliomesenchymal tumor, with only sixteen cases reported to date. In addition to the characteristic histology, metastasis-associated lung adenocarcinoma transcript 1 - glioma-associated oncogene homolog 1 gene fusion is typical, although recently novel ewing sarcoma breakpoint region 1 - c-terminal binding protein 1 and patched 1 - glioma-associated oncogene homolog 2 fusions have been described. Hepatoblastoma is exceptionally rare in adults and can show a variety of histologic patterns which may cause diagnostic difficulty. Pancreatoblastoma, primarily a pediatric tumor, displays acinar differentiation and squamoid nests with other lines of differentiation also present, especially neuroendocrine. Diagnostic approaches for these blastomas include a combination of imaging modalities, histopathological examination, and molecular profiling. The treatment generally involves surgical resection, which may be supplemented by chemotherapy or radiotherapy in some cases. Prognoses vary with gastroblastoma generally showing favorable outcomes post-surgery whereas hepatoblastoma and pancreatoblastoma often have poorer outcomes, particularly in the setting of metastases. This review highlights the complexity of diagnosing and managing these rare adult blastomas as well as the need for ongoing research to better understand their pathogenesis and improve treatment strategies.

Abstract
The extent of tumor spread influences on the clinical outcome, and which determine T stage of colorectal cancer. However, pathologic discrimination between pT3 and pT4a in the eighth edition of the American Joint Committee on Cancer (AJCC)-TNM stage is subjective, and more objective discrimination method for deeply invasive advanced colon cancer is mandatory for standardized patient management. Peritoneal elastic laminal invasion (ELI) detected using elastic staining may increase the objective discrimination of deeply invasive advanced colon cancer. In this study, we constructed ELI study group to investigate feasibility, objectivity, and prognostic utility of ELI. Furthermore, pT classification using ELI was investigated based on these data. At first, concordance study investigated objectivity using 60 pT3 and pT4a colon cancers. Simultaneously, a multi-institutional retrospective study was performed to assess ELI's prognostic utility in 1202 colon cancer cases from 6 institutions. In the concordance study, objectivity, represented by κ, was higher in the ELI assessment than in pT classification. In the multi-institutional retrospective study, elastic staining revealed that ELI was a strong prognostic factor. The clinical outcome of pT3 cases with ELI was significantly and consistently worse than that of those without ELI. pT classification into pT3 without ELI, pT3 with ELI, and pT4a was an independent prognostic factor. In this study, we revealed that ELI is an objective method for discriminating deeply invasive advanced colon cancer. Based on its feasibility, objectivity, and prognostic utility, ELI can subdivide pT3 lesions into pT3a (without ELI) and pT3b (with ELI).

Abstract
Teeth consist of 3 mineralized tissues: enamel, dentin, and cementum. Tooth malformation, the most common craniofacial anomaly, arises from complex genetic and environmental factors affecting enamel structure, size, shape, and tooth eruption. Hyaluronic acid (HA), a primary extracellular matrix component, contributes to structural and physiological functions in periodontal tissue. Transmembrane protein 2 (TMEM2), a novel cell surface hyaluronidase, has been shown to play a critical role during embryogenesis. In this study, we demonstrate Tmem2 messenger RNA expression in inner enamel epithelium and presecretory, secretory, and mature ameloblasts. Tmem2 knock-in reporter mice reveal TMEM2 protein localization at the apical and basal ends of secretory ameloblasts. Micro-computed tomography analysis of epithelial-specific Tmem2 conditional knockout (Tmem2-CKO) mice shows a significant reduction in enamel layer thickness and severe enamel deficiency. Enamel matrix protein expression was remarkably downregulated in Tmem2-CKO mice. Scanning electron microscopy of enamel from Tmem2-CKO mice revealed an irregular enamel prism structure, while the microhardness and density of enamel were significantly reduced, indicating impaired ameloblast differentiation and enamel matrix mineralization. Histological evaluation indicated weak adhesion between cells and the basement membrane in Tmem2-CKO mice. The reduced and irregular expressions of vinculin and integrin β1 suggest that Tmem2 deficiency attenuated focal adhesion formation. In addition, abnormal HA accumulation in the ameloblast layer and weak claudin 1 immunoreactivity in Tmem2-CKO mice indicate impaired tight junction gate function. Irregular actin filament assembly was also observed at the apical and basal ends of secretory ameloblasts. Last, we demonstrated that Tmem2-deficient mHAT9d mouse ameloblasts exhibit defective adhesion to HA-containing substrates in vitro. Collectively, our data highlight the importance of TMEM2 in adhesion to HA-rich extracellular matrix, cell-to-cell adhesion, ameloblast differentiation, and enamel matrix mineralization.

Abstract
A key aspect to vaccine efficacy is formulation stability. Biochemical evaluations provide information on optimal compositions or thermal stability but are routinely validated by ex vivo analysis and not efficacy in animal models. Here we assessed formulations identified to improve or reduce stability of the mucosal adjuvant dmLT being investigated in polio and enterotoxigenic E. coli (ETEC) clinical vaccines. We observed biochemical changes to dmLT protein with formulation or thermal stress, including aggregation or subunit dissociation or alternatively resistance against these changes with specific buffer compositions. However, upon injection or mucosal vaccination with ETEC fimbriae adhesin proteins or inactivated polio virus, experimental findings indicated immunization route and co-administered antigen impacted vaccine immunogenicity more so than dmLT formulation stability (or instability). These results indicate the importance of both biochemical and vaccine-derived immunity assessment in formulation optimization. In addition, these studies have implications for use of dmLT in clinical settings and for delivery in resource poor settings.

Abstract
Background
Cryoballoon ablation (CBA) is a useful treatment for pulmonary vein isolation (PVI). Some cases, however, are difficult to treat and may require multiple freezing procedures and/or touch-up ablation. Although several predictors of CBA difficulty have been reported, no report has been able to assess the spatial location and morphology of the left atrium (LA) and pulmonary veins (PVs). A polygonal mesh is a collection of vertices, edges, and faces that defines the shape of a polyhedral object, and is able to represent a spatial location with a small amount of information. We hypothesized that a deep learning model that learns mesh representation datasets could more accurately detect the CBA difficulty and that we could establish a novel evaluation method in CBA.
Purpose
The aim of this study was to create a model to predict CBA difficulty with a 3D deep learning model using polygonal mesh representation.
Methods and results
All the 140 patients who underwent CBA for drug-resistant atrial fibrillation between January 2015 and January 2022 were included. A 28-mm cryoballoon (Arctic Front Advance, Medtronic) was used in all cases. We defined CBA difficulty as requiring a touch-up ablation procedure to create complete PVI. We converted the volume data in DICOM format of the computed tomography images of PVs and LA to obj file format (shown in Figure 1), which supports the definition of the geometry for object surfaces using polygonal meshes. Next, we developed a deep learning model that could learn polygonal meshes and classify whether the CBA required touch-up ablation or not. Only a training dataset is used to train the deep learning model, and finally, a test dataset is used to evaluate the model metrics. The accuracy, area under the ROC curve, recall, precision, and f1-score of the deep learning model using the test dataset was 86.5%, 87.7%, 66.7%, 75.0%, 70.6%, respectively.
Conclusions
We developed a 3D deep learning model that can detect a difficulty in CBA using polygonal mesh representation. By predicting difficult cases in advance, we will be able to develop strategies to increase the success rate.

Abstract
Introduction The albumin-bilirubin (ALBI) grade is a novel indicator of the liver function. Some studies showed that the ALBI grade was a prognostic and predictive biomarker for the efficacy of chemotherapy in cancer patients. The association between the ALBI grade and outcomes in patients with non-small-cell lung cancer (NSCLC) treated with cancer immunotherapy, however, is poorly understood. Methods We retrospectively enrolled 452 patients with advanced or recurrent NSCLC who received anti-programmed cell death protein 1 (PD-1)-based therapy between 2016 and 2019 at three medical centers in Japan. The ALBI score was calculated from albumin and bilirubin measured at the time of treatment initiation and was stratified into three categories, ALBI grade 1-3, with reference to previous reports. We examined the clinical impact of the ALBI grade on the outcomes of NSCLC patients receiving anti-PD-1-based therapy using Kaplan–Meier survival curve analysis with log-rank test and Cox proportional hazards regression analysis. Results The classifications of the 452 patients were as follows: grade 1, n = 158 (35.0%); grade 2, n = 271 (60.0%); and grade 3, n = 23 (5.0%). Kaplan–Meier survival curve analysis showed that the ALBI grade was significantly associated with progression-free survival and overall survival. Moreover, Cox regression analysis revealed that the ALBI grade was an independent prognostic factor for progression-free survival and overall survival. Conclusion The ALBI grade was an independent prognostic factor for survival in patients with advanced or recurrent NSCLC who receive anti-PD-1-based therapy. These findings should be validated in a prospective study with a larger sample size. ALBI grade is calculated from albumin and bilirubin. We evaluated the impact of ALBI grade on survival in NSCLC patients receiving immune checkpoint inhibitors. ALBI grade was an independent prognostic factor for progression-free survival (PFS) and overall survival (OS). ALBI grade effectively stratified PFS and OS in patients with performance status 1-3. ALBI grade was significantly associated with PFS and OS, regardless of programmed death ligand-1.

Abstract
Abstract
Introduction/Objective
Although squamous cell carcinoma of the esophagus rarely metastasizes to the uncommon sites, colonic metastasis from squamous cell carcinoma of the esophagus is extremely rare. There has been no case report of colonic metastasis from squamous cell carcinoma of the esophagus to an anastomotic site of the colon.
Methods/Case Report
A 73-year-old female with a history of right hemicolectomy for advanced ascending colon cancer in 2006 was referred to our facility for a two-month history of solid food dysphagia. The patient has been followed up in the survivorship clinic for surveillance with no evidence of recurrence for 13 years to date. An esophagogastroduodenoscopy revealed a 7 cm fungating and ulcerated mass in the middle to lower esophagus. The biopsy from the esophageal mass showed a moderately to poorly differentiated squamous cell carcinoma. A colonoscopy showed an end-to-end ileocolonic anastomosis with a 7 mm ulceration in the transverse colon. The biopsy from the ulceration at the anastomotic site showed a moderately to poorly differentiated squamous cell carcinoma. Immunostains performed on both esophageal and colonic biopsies demonstrate that the tumor cells in both esophageal and colonic biopsies are positive for p40, p63, p16, and negative for CK7, CK20, and CDX2. The diagnosis of metastatic esophageal squamous cell carcinoma to the colonic anastomotic site of previous right hemicolectomy was rendered based on the morphology and immunoprofile. A subsequent computed tomography (CT) and positron emission tomography (PET) demonstrated no other distant metastases. Chemotherapy with 5-FU and oxaliplatin has been started.
A metastasis to the anastomotic site is extremely rare. Although the anastomotic site might be a good niche for cancer cells to metastasize to, the pathogenesis of a metastasis to the anastomotic site remains unknown. Our case is very intriguing because a metastasis occurred at the anastomosis site, and no other metastasis was found.
Results (if a Case Study enter NA)
N/A
Conclusion
We have reported the first case of metastatic esophageal squamous cell carcinoma to the colonic anastomotic site of previous right hemicolectomy in a 73-year-old female. Although the pathogenesis of a metastasis to the anastomotic site remains unknown, the possibility of contribution of surgical trauma to metastasis formation at the ileocolonic anastomosis cannot be completely ruled out.

Abstract
Abstract
Introduction/Objective
Foveolar hyperplastic polyp is a common gastric polyp characterized by foveolar hyperplasia with erosion, acute and chronic inflammation, granulation tissue formation, and smooth muscle strands extending from the muscularis mucosae. Although foveolar hyperplastic polyps may rarely contain foci of dysplasia or invasive carcinoma, osseous metaplasia/heterotopic bone formation in foveolar hyperplastic polyps of the stomach is extremely rare with a few case reports.
Methods/Case Report
A 63-year-old female with a history of hypertension, sick sinus syndrome, and Hashimoto’s thyroiditis was referred to our facility for evaluation of a mass in segment eight of the liver. The liver biopsy showed a moderately differentiated adenocarcinoma, most consistent with intrahepatic cholangiocarcinoma. A screening gastrointestinal endoscopy revealed a 7-mm sessile polyp in the antrum. The polyp was removed with a cold snare. No other abnormalities were identified in the stomach. Sections of the polyp showed fragments of antral-type gastric mucosa with foveolar hyperplasia, erosion, acute and chronic inflammation, and focal granulation tissue formation. In addition, multiple foci of woven bone formation without bone marrow surrounding dilated gastric foveolae were identified. No Helicobacter infection, intestinal metaplasia, dysplasia or malignancy was identified histologically. Osseous metaplasia/heterotopic bone formation is a well-known finding reported in various neoplastic and non- neoplastic conditions. However, osseous metaplasia in foveolar hyperplastic polyps of the stomach is extremely rare. There have been only four previous case reports published in English language. Our current case shows clinicopathologic features similar to those of the previous case reports including the findings of small-sized polyp found incidentally in middle-aged patients with no clinical history of hypercalcemia or any other abnormalities causing heterotopic bone formation.

Conclusion
Although the pathogenesis of osseous metaplasia in a gastric hyperplastic polyp remains unknown, the finding of osseous metaplasia in a gastric hyperplastic polyp is very intriguing.

Abstract
The increasing use of gastrointestinal endoscopic procedures has led to the recognition by histopathologists of non-conventional (or special-type) dysplasias of the gastrointestinal tract. These lesions can be recognised in association with prevalent underlying gastrointestinal conditions, such as Barrett oesophagus, chronic atrophic gastritis, and inflammatory bowel disease. The diagnosis of these special types can be challenging, and their biological behaviours are not fully characterised. The aim of this review is to provide a global view of non-conventional dysplastic lesions observed in the various segments of the tubular gastrointestinal tract and describe their salient features. Furthermore, as the clinical implications of these various subtypes have not been broadly tested in practice and are not represented in most management guidelines, we offer guidance on the best management practices for these lesions.

Abstract
BACKGROUND Endocytoscope systems (ECS) can visualize cellular nuclei of the mucosa of the gastrointestinal tract and are predicted to provide real-time microscopic diagnosis. However, their practical diagnostic performance remains unclear. Therefore, we conducted a multicenter prospective study to evaluate the visualization of superficial esophageal neoplasm in vivo using an ECS, and its diagnostic capability. METHODS The study target was histologically confirmed squamous cell carcinoma (SCC) and high-grade intraepithelial neoplasia (HGIN). An integrated ECS was used to obtain ECS images. In each patient, three ECS images of cancerous and corresponding noncancerous regions were selected for evaluation. A pathological review board of five certified pathologists made the final diagnosis of the images. The primary endpoint was the sensitivity of ECS diagnosis by pathologists. RESULTS ECS images of 68 patients were assessed: 42 lesions were mucosal SCC, 13 were submucosal SCC, and 13 were HGIN. The rate of assessable images was 96% (95% CI 87.6-99.1). The sensitivity of ECS diagnosis by pathologists was 88% (95% CI 77.2-94.5). CONCLUSIONS ECS can provide high-quality images of cancerous lesions and a high diagnostic accuracy by pathologists, and could be useful for real-time endoscopic histological diagnosis of SCC and HGIN.

Abstract
Herbal remedies by using mangrove plants have been recognized in several countries, and
the plant materials are often consumed as a tea, which are infusions of dried plant parts
steeped in boiling water. These infusions from mangrove plants are believed to be
effective agents for treating and/or prevent infections, ailments, and diseases, and some
mangrove plants have attracted attention as functional food resources in recent years. To
reveal the beneficial properties of mangrove plants, clarification of the chemical
ingredient and its characteristics of mangrove plants is required. This study focused on
amino acids, which were functional ingredients (i.e., bioactive compounds) because amino
acids are expected to function as ‘functional ingredients’ in addition to conventional
‘nutrients’ in recent years. To demonstrate the further possibilities of mangrove tea, we
firstly evaluated the content of total amino acids in the leaf of several dominant mangrove
species with commercial teas as references. Next, we clarified the composition of amino
acids by using LC-MS analysis. As the results, free amino acid content (FAC) in leaf
sample of Rhizophora stylosa, Bruguira gymnorrhiza, Kandelia obovata, Avicennia
marina, Sonneratia alba, and Lumnitzera racemosa was 747, 1056, 946, 829, 623, and
896 mg/100 g DW, respectively. The FAC in all mangrove leaf samples were higher than
those in green tea of low price, black tea, oolong tea, barley tea, and mate tea. Moreover,
it was found that GABA accounts for over 10% of the total amino acid in the mangrove
leaf samples. Especially in mature leaves of K. obovata, the ratio was very high levels
35%. In the case of K. obovata, the contents were higher than GABA tea. Based on this,
we concluded that several mangrove plants, especially K. obovata has the potential of a
functional food which is GABA-rich.

Abstract
There is a well-known discrepancy between East and West classifications of colorectal neoplasm, especially "intramucosal carcinoma," categorized as subgroup 4.4 in the Vienna classification, usually recognized as high-grade dysplasia in the United States and as carcinoma in situ in Japan. Focusing on management, in the current National Comprehensive Cancer Network algorithm, high-grade dysplasia, carcinoma in situ, and intramucosal carcinoma are managed similarly, whereas submucosal invasion by carcinoma requires en bloc resection. To bridge the differences with regard to these conceptual problems in the definition and management of carcinoma in situ and intramucosal carcinoma, endoscopists and pathologists from Japan and the United States gathered and discussed from their perspectives how to accurately assess specimens of en bloc/piecemeal resection and to effectively predict lymph node metastasis risk.

Abstract
Enterotoxin-based adjuvants including cholera toxin and heat-labile toxin (LT) are powerful manipulators of mucosal immunity; however, past clinical trials identified unacceptable neurological toxicity when LT or mutant AB5 adjuvant proteins were added to intranasal vaccines. Here, we examined the isolated enzymatic A1 domain of LT (LTA1) for intranasal safety and efficacy in combination with influenza (flu) vaccination. LTA1-treated mice exhibited no neurotoxicity, as measured by olfactory system testing and H&E staining of nasal tissue in contrast with cholera toxin. In vaccination studies, intranasal LTA1 enhanced immune responses to inactivated virus antigen and subsequent protection against H1N1 flu challenge in mice (8-week or 24-months). In addition, lung H1N1 viral titers post-challenge correlated to serum antibody responses; however, enhanced protection was also observed in μMT mice lacking B-cells while activation and recruitment of CD4 T-cells into the lung was apparent. Thus, we report that LTA1 protein is a novel, safe and effective enterotoxin adjuvant that improves protection of an intranasal flu vaccination by a mechanism that does not appear to require B-cells.

Abstract
A 72-year-old man was referred to the inflammatory bowel disease clinic for evaluation for possible Crohn disease. The patient was diagnosed with pan-ulcerative colitis in the late 1960s. He had medically refractory disease and required a total proctocolectomy with end ileostomy in the early 1970s. Since surgery, the patient has done well with his end ileostomy and has not required any inflammatory bowel disease medications. Over the past 14 months, he has developed intermittent foul-smelling serosanguinous drainage from his previous drained pilonidal cyst. His local gastroenterologist raised the concern for possible Crohn disease with perianal involvement. He has a significant family history of Crohn disease in his father. Past medical history includes chronic kidney disease, hypertension, diabetes, coronary artery disease, gout, and arthritis. Esophagogastroduodenoscopy (EGD) revealed diffuse brown to black speckled/tigroid spots in the entire examined duodenum. Duodenal biopsy showed scattered clusters of macrophages containing dark pigmented granules within the apical tips of the lamina propria. These pigmented granules were focally positive with iron staining. No villous blunting, intraepithelial lymphocytosis, granuloma, or significant inflammation was identified. The distinctive endoscopic and histologic features are diagnostic of pseudomelanosis duodeni. Pseudomelanosis duodeni is a rare benign entity characterized by diffuse black tigroid spots and aggregates of pigment-laden macrophages in the lamina propria. Results of iron staining are characteristically variable. Pseudomelanosis duodeni is seen in middle-aged to elderly adults. Most of the patients with pseudomelanosis duodeni are asymptomatic. Although the exact etiology remains unknown, pseudomelanosis duodeni has been reported to be associated with several medical conditions such as end-stage renal disease, hypertension, diabetes, heart failure, gastrointestinal hemorrhage, and medications, including oral iron therapy, furosemide, hydralazine, thiazide, and iron sulfate. Pathologists should be aware of this rare condition of the duodenum to make an accurate diagnosis of this rare entity.

Abstract
Abstract
Epidermoid cyst in the intrapancreatic accessory spleen (ECIAS) is an exceedingly rare nonneoplastic entity. It generally does not require therapeutic intervention, but it is often misdiagnosed preoperatively as a cystic tumor, such as a mucinous cystic neoplasm or a cystic degeneration in a solid pancreatic neuroendocrine tumor or solid pseudopapillary neoplasm. We herein report a rare case of ECIAS in a 33-year-old African American man with a history of end-stage renal disease secondary to IgA nephropathy, congestive heart failure, and sickle cell trait who was referred to our facility for a renal transplant workup. A contrast-enhanced abdominal computed tomography during the workup revealed a bilobed low attenuating mass (3.4 × 3.4 × 2.5 cm) in the tail of the pancreas. Because malignancy could not be excluded, the patient underwent a distal pancreatectomy and splenectomy. Gross examination of the surgical specimen revealed a smooth-walled, multiloculated cyst (3.7 × 2.7 × 2.0 cm), containing serous fluid within the pancreatic parenchyma. Microscopically, the cyst was lined by nonkeratinizing stratified squamous epithelium without skin appendages, surrounded by benign splenic tissue in the pancreatic parenchyma. No dysplasia or malignancy was seen. Immunohistochemically, the lining epithelium was positive for p63, CK5/6, and CEA and negative for CA19-9, which supports the above diagnosis. The postoperative course was uneventful. In conclusion, ECIAS is a rare benign entity that can mimic malignant conditions and should be considered in the differential diagnosis of cystic lesions in the tail of pancreas.

Abstract
Abstract
Pyogenic granuloma also known as lobular capillary hemangioma occurs commonly in the skin and oral mucosa. This entity has been rarely reported in the gastrointestinal tract. We herein report three cases of pyogenic granuloma, located in the duodenum, ileum, and rectum, respectively. Case 1 is a 54-year-old female with a history of angioimmunoblastic T-cell lymphoma who underwent an esophagogastroduodenoscopy for severe heartburn. The endoscopy showed a 13-mm nonbleeding, pedunculated polyp in the second portion of duodenum, which was removed using a hot snare after injection of epinephrine. The patient had an episode of massive gastrointestinal bleeding postpolypectomy, with a significant drop of her hemoglobin, which was managed with blood transfusion. Case 2 is a 68-year-old male with a history of right hemicolectomy due to trauma who had a colonoscopy for chronic diarrhea. The colonoscopy revealed a 14-mm, nonbleeding, pedunculated polyp in the ileum, located 3 cm from the ileocolonic anastomosis. The polyp was removed with hot snare, without complications. Case 3 is a 44-year-old female with morbid obesity who underwent a colonoscopy for iron-deficiency anemia. The colonoscopy showed an 8-mm multilobulated sessile lesion in the distal rectum, which was completely removed using hot snare. No complications were seen postpolypectomy. Histological examination of all the three polyps showed a proliferation of capillary-sized blood vessels with a mixed inflammatory infiltrate, resembling granulation tissue. Additionally, the ileal polyp in our case had marked eosinophilic infiltrate, the etiology of which remains unknown. In conclusion, pyogenic granuloma, given its vascular nature, can be a cause of bleeding in the gastrointestinal tract. Awareness regarding this rare entity is important for its proper diagnosis and treatment.

Abstract
Clear cell adenocarcinoma (CCA) in lung has been considered as a rare subtype of lung adenocarcinoma. However, recent classifications of lung adenocarcinoma proposed to discontinue CCA due to lack of available data with clinical significance. Patients with CCA and lung adenocarcinoma not otherwise specified (LANOS) were queried from The Surveillance, Epidemiology, and End Results Program (SEER) database. Cancer-specific survival was studied according to gender (male, female), age (0-69, 70+), SEER specific stage A system (localized, regional and distant), year of diagnosis (1973-2000, 2001-2013), surgery (yes, no), and radiation therapy (yes, no) using Kaplan-Meier curves. Multivariate analysis was used to study independent predictors of cancer-specific survival. A total of 1,227 and 233,154 patients with the diagnosis of CCA and LANOS respectively were found in the SEER database. CCA histology was significantly associated with an early year of diagnosis, younger age, early stage, surgery, and lack of radiation. Kaplan-Meier curves showed that patients with CCA histology had significantly better cancer-specific survival (P<0.0001, Log-Rank). Subset analysis demonstrated the difference in cancer-specific survival between CCA and NOS histology was significant in localized and regional but not distant stage disease (P=0.0453, 0.0009, 0.0664, respectively). Patients with CCA histology have superior survival in the locoregional stage according to our SEER analysis, suggesting its unique role in prognosis despite it being removed from recent pathologic classifications.

Abstract
Although they are known to share pathophysiological processes, the relationship between periodontitis and chronic obstructive pulmonary disease (COPD) is not fully understood. The aim of the present study was to test the hypothesis that periodontitis is associated with a greater risk of development of COPD, when smoking is taken into account. The analysis in a 5-y follow-up population-based cohort study was based on 900 community-dwelling Japanese adults (age: 68.8 ± 6.3 [mean ± SD], 46.0% male) without COPD aged 60 or older with at least 1 tooth. Participants were classified into 3 categories according to baseline periodontitis severity (no/mild, moderate, and severe). COPD was spirometrically determined by a fixed ratio of <0.7 for forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) and by FEV1/FVC below the lower limit of normal. Poisson regression was used to calculate the relative risk (RR) of developing COPD according to the severity of periodontitis. The population attributable fraction (PAF) was also calculated. During follow-up, 22 (2.4%) subjects developed COPD. Compared with no/mild periodontitis subjects, a significantly increased risk of COPD occurred among severe periodontitis subjects (RR = 3.55; 95% confidence interval [CI], 1.18 to 10.67), but no significant differences were observed between the no/mild and moderate categories (RR = 1.48; 95% CI, 0.56 to 3.90). After adjustment for potential confounders, including smoking intensity, the relationship between severe periodontitis and risk of COPD remained significant (RR = 3.51; 95% CI, 1.15 to 10.74). Likewise, there was a positive association of periodontitis severity with risk of COPD ( P for trend = 0.043). The PAF for COPD due to periodontitis was 22.6%. These data highlight the potential importance of periodontitis as a risk factor for COPD.

Abstract
Continuous cell monitoring is very important for the maintenance and control of cell multiplication and differentiation. This paper presents a compact microplate reader that is able to continuously measure a 24-well microplate (6 × 4 wells) using the optical absorption measurement method. The 24-channel plate reader consisted of a spatial filter, light emitting diode light source, and color sensors and was similarly sized with the cell culture microwell plates. A spatial filter was previously fabricated by our group using silicone optical technology (SOT). This SOT-based spatial filter has an excellent noise reduction effect. Light reflection at the optical path interface can be absorbed and only forward light can be transmitted; accordingly, a larger S/N ratio than that of conventional optical systems is expected. The fabricated 24-channel plate reader permits real-time cell monitoring during cultivation on the clean bench and in cell culture conditions by incorporating the SOT spatial filter. Using the device, it was possible to continuously evaluate the concentration and pH of reagents in the 24 wells in real time. Moreover, cell activity and protein production were detectable using the device. These results suggest that the newly fabricated device is a promising tool for the evaluation of cell behaviors for cell management.

Abstract
The T2K experiment measures muon neutrino disappearance and electron neutrino appearance in accelerator-produced neutrino and antineutrino beams. With an exposure of 14.7(7.6)×10^{20} protons on target in the neutrino (antineutrino) mode, 89 ν_{e} candidates and seven anti-ν_{e} candidates are observed, while 67.5 and 9.0 are expected for δ_{CP}=0 and normal mass ordering. The obtained 2σ confidence interval for the CP-violating phase, δ_{CP}, does not include the CP-conserving cases (δ_{CP}=0, π). The best-fit values of other parameters are sin^{2}θ_{23}=0.526_{-0.036}^{+0.032} and Δm_{32}^{2}=2.463_{-0.070}^{+0.071}×10^{-3} eV^{2}/c^{4}.

Abstract
Colonic macrophages induce pathogenic inflammation against commensal bacteria, leading to inflammatory bowel disease (IBD). Although the ontogeny of colonic macrophages has been well studied in the past decade, how macrophages gain colitogenic properties during the development of colitis is unknown. Using a chemically induced colitis model, we showed that accumulated Ly6C+ cells consisting of inflammatory monocytes and inflammatory macrophages strongly expressed representative colitogenic mediators such as tumor necrosis factor-α (TNF-α) and inducible nitric oxide synthase (iNOS). The interferon-γ-signal transducer and activator of transcription 1 (IFN-γ-Stat1) pathway was required for generating colitogenic macrophages, given that Stat1-/- mice had less severe colitis and fewer colitogenic macrophages. Notably, IFN-γ induced histone acetylation at the promoter regions of the Tnf and Nos2 loci in the monocyte and macrophage lineage, indicating that IFN-γ-dependent epigenetic regulation instructs the development of the colitogenic monocyte and macrophage lineage in vivo. Collectively, our results provide the essential mechanism by which dysregulated colitogenic monocytes/macrophages develop at the colon mucosa during inflammation, and suggest a new drug target for treating IBD.

Abstract
Foxp3+ Regulatory T cells (Tregs) play a critical role in the maintenance of colon homeostasis. Here we utilized photoconvertible KikGR mice to track immune cells from the caecum and ascending (proximal) colon in the steady state and DSS-induced colitis. We found that Tregs from the proximal colon (colonic migratory Tregs) migrated exclusively to the distal part of mesenteric lymph nodes (dMLN) in an S1PR1-dependent process. In the steady state, colonic migratory CD25+ Tregs expressed higher levels of CD103, ICOS, LAG3 and CTLA-4 in comparison with pre-existing LN Tregs. Intestinal inflammation led to accelerated Treg replacement in the colon, bidirectional Treg migration from the colon to dMLN and vice versa, as well as increases in Treg number, proliferation and expression of immunosuppressive molecules. This was especially apparent for CD25 very high Tregs induced in colitis. Furthermore, colonic migratory Tregs from the inflamed colon included more interleukin (IL)-10 producing cells, and demonstrated greater inhibition of T-cell proliferation in comparison with pre-existing LN Tregs. Thus, our results suggest that Tregs with superior immunosuppressive capacity are increased both in the colon and dMLN upon inflammation. These Tregs recirculate between the colon and dMLN, and are likely to contribute to the downregulation of intestinal inflammation.
