Antifungal activities of vineyard-habitat wild yeast for grape gray-mold disease and its effects on spontaneous winemaking.

Microorganisms, including native yeasts, are abundant in vineyard fields. Herein, we studied the possibility of using vineyard-derived wild yeast as a microbial pesticide against Botrytis cinerea, a pathogen that causes grape gray mold disease, to boost the initial alcohol production of spontaneously fermented wine. We identified the Saccharomyces cerevisiae strain KONDO170908, which showed the most effective antifungal activity in an ex vivo yeast dripping experiment on grape berries. This strain was utilized in an in vivo spray test on grape bunches in vineyard fields and was proven to significantly suppress gray mold disease on the grape berries in test plot #16 when the yeast was sprayed during both the flowering and ripening periods (morbidity 11.2% against 15.3% of the control plot, χ2 test, p < 0.0001). However, in test plot #17, spraying the yeast during only the ripening period had no effect (morbidity 16.3%). The grapes from each test plot were also submitted for spontaneous wine fermentation. Alcoholic fermentation of the grapes from test plot #16 provided the most active bubbling of CO2 gas and the highest ethanol production and colony counts over seven days of fermentation. Unique changes in the different strains of S. cerevisiae among the plots were observed throughout the early fermentation stage. Thus, yeast spraying during the flowering period might trigger modification of the entire microbiota and could ultimately contribute to promoting alcohol production in the spontaneously fermented wine, although it decreased the grape yield by 20%.

A Comparative Study on Fungal Diversity in Organic and Conventionally Cultivated Lemons During Accelerated Storage.

There has been a growing interest in organic farming as a countermeasure to the environmental burden caused by chemical pesticides. We analyzed and compared the fungal diversity of lemon fruits from organic and conventional cultivation by automated rRNA intergenic spacer analysis (ARISA), accompanied by isolation of cultured colonies and metagenomic analysis. Lemon peels were cut out and subjected to the analyses at purchase and after accelerated storage at 28 °C. The organic lemons did not decay even after 14 weeks, while most of the conventional lemons did decay. The fungal colony counts were not significantly different, although the number of fungal species together with the Shannon index, considering the abundance of each species, clearly showed more diversity in organic lemons than in conventional lemons (p = 0.011). Fusarium sp. (putative F. solani) accounted for as much as 90% of the relative abundance in the decayed conventional lemons. Metagenomic analysis also supported the lack of fungal diversity in conventional lemons. These results may suggest that organic cultivation maintains the diversity of native fungal flora in lemon fruit and could contribute to preventing decay during ambient storage.

MELAS-Derived Neurons Functionally Improve by Mitochondrial Transfer from Highly Purified Mesenchymal Stem Cells (REC).

Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episode (MELAS) syndrome, caused by a single base substitution in mitochondrial DNA (m.3243A>G), is one of the most common maternally inherited mitochondrial diseases accompanied by neuronal damage due to defects in the oxidative phosphorylation system. There is no established treatment. Our previous study reported a superior restoration of mitochondrial function and bioenergetics in mitochondria-deficient cells using highly purified mesenchymal stem cells (RECs). However, whether such exogenous mitochondrial donation occurs in mitochondrial disease models and whether it plays a role in the recovery of pathological neuronal functions is unknown. Here, utilizing induced pluripotent stem cells (iPSC), we differentiated neurons with impaired mitochondrial function from patients with MELAS. MELAS neurons and RECs/mesenchymal stem cells (MSCs) were cultured under contact or non-contact conditions. Both RECs and MSCs can donate mitochondria to MELAS neurons, but RECs are more excellent than MSCs for mitochondrial transfer in both systems. In addition, REC-mediated mitochondrial transfer significantly restored mitochondrial function, including mitochondrial membrane potential, ATP/ROS production, intracellular calcium storage, and oxygen consumption rate. Moreover, mitochondrial function was maintained for at least three weeks. Thus, REC-donated exogenous mitochondria might offer a potential therapeutic strategy for treating neurological dysfunction in MELAS.

[A Case of Curative Resection of the Local Advanced Gastric Cancer after SOX plus Nivolumab Chemotherapy, and the Pathological Diagnosis Was Complete Response].

A-78-year-old woman presented with difficulty swallowing. She was diagnosed as having advanced upper gastric cancer with invasion to the esophagus and the diaphragm. Biopsy examination of the tumor showed MSI-high and HER2-negative. The patient received 4 courses of SOX plus nivolumab in combination. After the chemotherapy, the size of the tumor decreased remarkably. We performed total gastrectomy with D2 lymph node dissection. Pathological examination revealed no residual cancer at the primary tumor location and the regional lymph nodes. The patient has shown no recurrence for 9 months without adjuvant chemotherapy. We conclude that SOX plus nivolumab in combination as first-line chemotherapy is an effective strategy against advanced gastric cancer.

[A Patient with Gastric Adenosquamous Cell Carcinoma].

A 73-year-old female was referred from a local clinic with abdominal pain. A diagnosis of gastric cancer(cT3, cN0, M0, cStage ⅡB)and acute cholecystitis was made. Distal gastrectomy, D2, and cholecystectomy were performed. Postoperative pathological examination led to a diagnosis of adenosquamous cell carcinoma(pT3, pN2, M0, pStage ⅢA). SOX therapy was administered as postoperative adjuvant chemotherapy. However, multiple liver metastases were detected. XP and DTX therapies were administered; however, there was a reduction in performance status. The patient died 10 months after surgery. Gastric adenosquamous cell carcinoma is classified as a specific type according to the Japanese Classification of Gastric Carcinoma(15th edition). This carcinoma accounts for 0.3 to 0.5% of patients undergoing gastric cancer surgery and is relatively rare. Its malignancy level is higher than that of gastric adenocarcinoma, and its prognosis is poorer.

[A Strategy of Treatment for Perforated Gastric Cancer].

In past reports, the incidence of gastric perforation accounts for 0.08 to 3.6% of all gastric cancers, and the proportion of perforated gastric cancer(PGC)in gastric perforations is 26 to 32%. In the treatment of PGC, critical care for peritonitis, diagnosis of gastric cancer and curability for gastric cancer are required simultaneously, so it is not easy to decide the treatment strategies. Therefore, for the purpose to consider treatment strategies for PGC, we conducted a clinicopathological study on PGC in our hospital for the past 12 years. There were 22 cases of PGC, and we analyzed clinicopathologically 19 cases excluding perforation during endoscopic resection and perforation during chemotherapy. The R0 surgery group tended to have a good prognosis even in PGC cases, and there was surgery-related death in the one-stage gastrectomy group. So it was considered desirable to perform radical surgery after the general condition was stable by the treatment of peritonitis was given priority in the PGC.

C-C motif chemokine receptor 9 regulates obesity-induced insulin resistance via inflammation of the small intestine in mice.

AIMS/HYPOTHESIS: Accumulation of adipose tissue macrophages is considered pivotal in the development of obesity-associated inflammation and insulin resistance. In addition, recent studies suggest an involvement of the intestine as the primary organ in inducing hyperglycaemia and insulin resistance. We have reported that the C-C motif chemokine receptor (CCR) CCR9 is associated with intestinal immunity and has a pathogenic role in various liver diseases. However, its contribution to type 2 diabetes is unknown. In the current study, we aimed to clarify the involvement of CCR9 in the pathology of type 2 diabetes and the potential underlying mechanisms. METHODS: To elucidate how CCR9 affects the development of metabolic phenotypes, we examined the impact of CCR9 deficiency on the pathogenesis of type 2 diabetes using male C57BL/6J (wild-type [WT]) and CCR9-deficient (CCR9 knockout [KO]) mice fed a 60% high-fat diet (HFD) for 12 weeks. RESULTS: WT and Ccr9KO mice fed an HFD exhibited a comparable weight gain; however, glucose tolerance and insulin resistance were significantly improved in Ccr9KO mice. Moreover, visceral adipose tissue (VAT) and the liver of Ccr9KO mice presented with less inflammation and increased expression of glucose metabolism-related genes than WT mice. Ccr9 and Ccl25 expression were specifically higher in the small intestine but was not altered by HFD feeding and type 2 diabetes development. Accumulation of IFN-γ-producing CD4+ T lymphocytes and increased intestinal permeability in the small intestine was observed in WT mice following HFD feeding, but these changes were suppressed in HFD-fed Ccr9KO mice. Adoptive transfer of gut-tropic CCR9-expressing T lymphocytes partially reversed the favourable glucose tolerance found in Ccr9KO mice via exacerbated inflammation in the small intestine and VAT. CONCLUSIONS/INTERPRETATION: CCR9 plays a central role in the pathogenesis of type 2 diabetes by inducing an inflammatory shift in the small intestine. Our findings support CCR9 as a new therapeutic target for type 2 diabetes via the gut-VAT-liver axis.

Mutations in CHCHD2 cause α-synuclein aggregation.

Mutations in CHCHD2 are linked to a familial, autosomal dominant form of Parkinson's disease (PD). The gene product may regulate mitochondrial respiratory function. However, whether mitochondrial dysfunction induced by CHCHD2 mutations further yields α-synuclein pathology is unclear. Here, we provide compelling genetic evidence that mitochondrial dysfunction induced by PD-linked CHCHD2 T61I mutation promotes α-synuclein aggregation using brain autopsy, induced pluripotent stem cells (iPSCs) and Drosophila genetics. An autopsy of an individual with CHCHD2 T61I revealed widespread Lewy pathology with both amyloid plaques and neurofibrillary tangles that appeared in the brain stem, limbic regions and neocortex. A prominent accumulation of sarkosyl-insoluble α-synuclein aggregates, the extent of which was comparable to that of a case with α-synuclein (SNCA) duplication, was observed in CHCHD2 T61I brain tissue. The prion-like activity and morphology of α-synuclein fibrils from the CHCHD2 T61I brain tissue were similar to those of fibrils from SNCA duplication and sporadic PD brain tissues. α-Synuclein insolubilization was reproduced in dopaminergic neuron cultures from CHCHD2 T61I iPSCs and Drosophila lacking the CHCHD2 ortholog or expressing the human CHCHD2 T61I. Moreover, the combination of ectopic α-synuclein expression and CHCHD2 null or T61I enhanced the toxicity in Drosophila dopaminergic neurons, altering the proteolysis pathways. Furthermore, CHCHD2 T61I lost its mitochondrial localization by α-synuclein in Drosophila. The mislocalization of CHCHD2 T61I was also observed in the patient brain. Our study suggests that CHCHD2 is a significant mitochondrial factor that determines α-synuclein stability in the etiology of PD.

Role of CC chemokine receptor 9 in the progression of murine and human non-alcoholic steatohepatitis.

BACKGROUND & AIMS: The number of patients with non-alcoholic steatohepatitis (NASH) is increasing globally. Recently, specific chemokine receptors have garnered interest as therapeutic targets in NASH. This is the first report to examine the role of the C-C chemokine receptor 9 (CCR9)/C-C chemokine receptor ligand 25 (CCL25) axis, and to reveal its therapeutic potential in NASH. METHODS: Patients with biopsy-proven non-alcoholic liver disease (NAFLD) were recruited and their serum and hepatic chemokine expression was examined. Furthermore, wild-type (WT) and Ccr9-/- mice were fed a high-fat high-cholesterol (HFHC) diet for 24 weeks to establish NASH. RESULTS: Serum CCL25, and hepatic CCR9 and CCL25 expression levels were increased in patients with NASH compared to healthy volunteers. Furthermore, Ccr9-/- mice were protected from HFHC diet-induced NASH progression both serologically and histologically. Flow cytometry and immunohistochemistry analysis showed that CCR9+CD11b+ inflammatory macrophages accumulated in the inflamed livers of HFHC diet-fed mice, while the number was reduced in Ccr9-/- mice. Consistent with human NASH livers, CCR9 was also expressed on hepatic stellate cells (HSCs) in mice with NASH, while CCR9-deficient HSCs showed less fibrogenic potential in vitro. Administration of a CCR9 antagonist hampered further fibrosis progression in mice with NASH, supporting its potential clinical application. Finally, we showed that CCR9 blockade attenuated the development of NAFLD-related hepatocellular carcinoma in HF diet-fed mice injected with diethylnitrosamine. CONCLUSIONS: These results highlight the role of the CCR9/CCL25 axis on macrophage recruitment and fibrosis formation in a murine NASH model, providing new insights into therapeutic strategies for NASH. LAY SUMMARY: Herein, we show that a specific chemokine axis involving a receptor (CCR9) and its ligand (CCL25) contributes to the progression of non-alcoholic steatohepatitis and carcinogenesis in humans and mice. Furthermore, treatment with a CCR9 antagonist ameliorates the development of steatohepatitis and holds promise for the treatment of patients with non-alcoholic steatohepatitis.

Compact and adjustable compensator for AOD spatial and temporal dispersion using off-the-shelf components.

Random access multiphoton microscopy using two orthogonal acousto-optic deflectors (AODs) allows sampling only particular regions of interest within a plane, greatly speeding up the sampling rate. AODs introduce spatial and temporal dispersions, which distort the point spread function and decrease the peak intensity of the pulse. Both of these effects can be compensated for with a single dispersive element placed a distance before the AODs. An additional acousto-optic modulator, a custom cut prism, and a standard prism used with additional cylindrical optics have been demonstrated. All of these introduce additional cost or complexity and require an extended path length to achieve the needed negative group delay dispersion (GDD). By introducing a telescope between a transmission grating and the AODs, we correct for spatial and temporal dispersions in a compact design using only off-the-shelf components, and we show that the GDD can be tuned by translation of the telescope without adjustment of any other elements.

Soluble epoxide hydrolase plays a key role in the pathogenesis of Parkinson's disease.

Parkinson's disease (PD) is characterized as a chronic and progressive neurodegenerative disorder, and the deposition of specific protein aggregates of α-synuclein, termed Lewy bodies, is evident in multiple brain regions of PD patients. Although there are several available medications to treat PD symptoms, these medications do not prevent the progression of the disease. Soluble epoxide hydrolase (sEH) plays a key role in inflammation associated with the pathogenesis of PD. Here we found that MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine)-induced neurotoxicity in the mouse striatum was attenuated by subsequent repeated administration of TPPU, a potent sEH inhibitor. Furthermore, deletion of the sEH gene protected against MPTP-induced neurotoxicity, while overexpression of sEH in the striatum significantly enhanced MPTP-induced neurotoxicity. Moreover, the expression of the sEH protein in the striatum from MPTP-treated mice or postmortem brain samples from patients with dementia of Lewy bodies (DLB) was significantly higher compared with control groups. Interestingly, there was a positive correlation between sEH expression and phosphorylation of α-synuclein in the striatum. Oxylipin analysis showed decreased levels of 8,9-epoxy-5Z,11Z,14Z-eicosatrienoic acid in the striatum of MPTP-treated mice, suggesting increased activity of sEH in this region. Interestingly, the expression of sEH mRNA in human PARK2 iPSC-derived neurons was higher than that of healthy control. Treatment with TPPU protected against apoptosis in human PARK2 iPSC-derived dopaminergic neurons. These findings suggest that increased activity of sEH in the striatum plays a key role in the pathogenesis of neurodegenerative disorders such as PD and DLB. Therefore, sEH may represent a promising therapeutic target for α-synuclein-related neurodegenerative disorders.

[Clinicopathological Examination of 81 Cases Added Gastrectomy for Early Gastric Cancer after ESD].

As a general rule, our department has performed additional gastrectomy with lymph node dissection(radical surgery: RS) for non-curative endoscopic submucosal dissection(ESD)cases. This time, we performed a clinicopathological study on 81 patients who underwent RS after ESD for 10 years from May 2009 to April 2019. Lymph node metastasis(LNM)was observed in 5 cases and local cancer residue(LCR)was observed in 8 cases. Examination of the presence or absence of LNM and LCR by clinicopathological factors(histopathological type, tumor size, lymphatic invasion[ly], venous invasion[v], horizontal margin[HM], vertical margin[VM], submucosal invasion, ulceration[scar])revealed no significant risk factor for LNM, however, tumor size and HM were significant risk factors for LCR. The relationship between the eCura system and the case rate associated with LNM in our hospital was similar to that in the original report. Regarding the prognosis, there was one local recurrence and no death from the primary disease.

Clinical implications with tolvaptan on monitored bioimpedance-defined fluid status in patients with cirrhotic ascites: an observational study.

BACKGROUND: Prognostic value or clinical implications of fluid status monitoring in liver cirrhosis are not fully elucidated. Tolvaptan, an orally available, selective vasopressin V2-receptor antagonist approved for hyponatremia in the United States and European Union. It is also used for cirrhotic ascites at a relatively low dose (3.75 mg to 7.5 mg) in Japan, exerts its diuretic function by excreting electrolyte-free water. We hypothesized that bioimpedance-defined dynamic changes in fluid status allow prediction of response of V2 antagonism and survival in cirrhotic patients. METHODS: In this prospective observational study, 30 patients with decompensated liver cirrhosis who were unresponsive to conventional diuretics were enrolled. Detailed serial changes of body composition that were assessed by using non-invasive bioimpedance analysis (BIA) devices, along with biochemical studies, were monitored at 5 time points. RESULTS: Sixteen patients were classified as short-term responders (53%). Rapid and early decrease of BIA-defined intracellular water, as soon as 6 h after the first dose (ΔICWBIA%-6 h), significantly discriminated responders from non-responders (AUC = 0.97, P < 0.0001). ΔICWBIA%-6 h was highly correlated with the change of BIA-derived phase angle of trunk, e.g. reduced body reactance operated at 50 kHz after 24 h of the first dose of tolvaptan. Lower baseline blood urea nitrogen and lower serum aldosterone were predictive of a rapid and early decrease of ICWBIA. A rapid and early decrease of ICWBIA in response to tolvaptan was also predictive of a better transplant-free survival. CONCLUSIONS: BIA-defined water compartment monitoring may help predict short-term efficacy and survival in decompensated cirrhotic patients treated with tolvaptan.

[A Case of Primary Gastric Adenocarcinoma with Enteroblastic Differentiation(GAED)].

Gastric adenocarcinoma with enteroblastic differentiation(GAED)is a rare disease that is classified as a special type in the 15th edition Japanese Classification of Gastric Carcinoma. GAED is considered to have a poor prognosis. We report about a 76-year-old man with GAED who presented with complaints of poor appetite and weight loss. He was suspected of having gastric cancer based on ultrasonography and computed tomography findings and was referred to our hospital by his home doctor. Upper gastrointestinal endoscopy revealed a gastric cancer in the lesser curvature of the gastric antrum. Distal gastrectomy was performed. Histopathology showed a moderately differentiated adenocarcinoma with a clear cytoplasm. Immunostaining was positive for Sal-like protein 4(SALL4)and negative for α-fetoprotein(AFP). The patient was diagnosed as having GAED. Vascular and lymphatic invasion were not observed. He was discharged on the 9th day after surgery. At 5 months postoperatively, he was treated with adjuvant chemotherapy, and no recurrence was noted. GAED is a rare disease with a poor prognosis. We report this case and discuss relevant literature.

Neuroprotective effects of memantine via enhancement of autophagy.

INTRODUCTION: Chemical intervention of autophagy has been investigated in clinical trials for various age-related conditions such as sarcopenia and neurodegeneration. However, at present, no autophagy inducer has been established as a disease-modifying agent against neurodegenerative diseases. METHODS: We screened a library consisting of 796 medicines clinically approved (in Japan) for autophagy enhancers as potential neurodegeneration therapeutics using HeLa cells stably expressing green fluorescent protein-microtubule-associated protein light chain 3 (GFP-LC3) followed by an analysis of the molecular mechanisms using various neuronal models. RESULTS: The primary screening identified 152 hits in a static cellular state. A widely available Alzheimer's disease drug, memantine, which antagonizes N-Methyl-d-aspartate receptor (NMDAR), was one of the hits. Memantine increased the levels of LC3-II in a dose-dependent and time-dependent manner, and upregulated autophagic flux. In addition, the pharmacological effects of memantine on autophagy were independent of mTORC1 activity and NMDAR activation. Furthermore, a VPS34 inhibitor suppressed the memantine-induced LC3-II upregulation, suggesting that memantine may affect VPS34 complex activity. Notably, intracellular Huntington's disease-specific aggregates of elongated huntingtin, a well-established autophagy substrate, were significantly decreased by memantine. In addition, memantine enhanced elimination of degraded mitochondrial in neurons derived from induced pluripotent stem cells of PARK2 or PARK6 patients, who exhibited defective PINK1/parkin-mediated mitophagy, suggests that memantine accelerated the clearance of damaged mitochondria. CONCLUSION: These findings indicate that memantine may be beneficial for the treatment of neurodegeneration characterized by the abnormal accumulation of autophagy or mitophagy substrates.

Microbial Diversity in the Edible Gall on White Bamboo Formed by the Interaction between Ustilago esculenta and Zizania latifolia.

An edible gall is formed between the third and fourth nodes beneath the apical meristem near the base of Zizania latifolia shoots. This gall is harbored by and interacts with the smut fungus Ustilago esculenta. The gall is also a valuable vegetable called "white bamboo," jiaobai or gausun in China and makomotake in Japan. Five samples of the galls harvested at different stages of swelling were used to isolate microorganisms by culturing. Isolated fungal and bacterial colonies were identified by DNA sequencing and matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry, respectively. Several strains of U. esculenta as well as 6 other species of fungi and 10 species of bacteria were isolated. The microbiome was also evaluated by simple and outlined DNA profiling with automated rRNA intergenic spacer analysis (ARISA), and the amount of DNA of U. esculenta was determined by qPCR. At least 16 species of fungi and 40 species of bacteria were confirmed by ARISA of the overall sample. Interestingly, the greatest bacterial diversity, i.e., 18 species, was observed in the most mature sample, whereas the fungal diversity observed in this sample, i.e., 4 species, was rather poor. Based on qPCR, U. esculenta occurred in samples from all stages; however, the abundance of U. esculenta exhibited unique U-shaped relationships with growth. These results may explain why the interaction between U. esculenta and Z. latifolia also influences the unique microbial diversity observed throughout the growth stages of the swollen shoot, although the limited sample size does not allow conclusive findings.

Chiral lyotropic chromonic liquid crystals composed of disodium cromoglycate doped with water-soluble chiral additives.

We investigated the pitches of cholesteric liquid crystals prepared by mixing disodium cromoglycate (DSCG) in water with 5 different water-soluble chiral additives. The measurements are based on the Grandjean-Cano wedge cell method. Overall, the twisting effect is weak, and the shortest pitch of 2.9 ± 0.2 µm is obtained using trans-4-hydroxy-l-proline, by which the cholesteric sample is iridescent at certain viewing angles. Freeze-fracture transmission electron microscopy (FFTEM) was also performed for the first time on both the nematic and cholesteric phases, revealing that stacked chromonic aggregates are very long, up to a few hundred nm, which explains why cholesteric chromonic liquid crystals hardly have pitches in the visible wavelength region.

Pseudorandom number generator based on the Bernoulli map on cubic algebraic integers.

We develop a pseudorandom bit generator using chaotic true orbits of the Bernoulli map on real cubic algebraic integers having complex conjugates. Although this generator has a high computational cost, it exactly simulates the Bernoulli map that can generate ideal random binary sequences. In particular, we clarify a seed selection method that can select initial points (i.e., seeds) without bias and can avoid overlaps in latter parts of the pseudorandom binary sequences derived from them. Moreover, in order to evaluate the memory usage of our generator, we give upper bounds concerning the growth of the representation of points on a true orbit. We also report results of a large variety of tests indicating that the generated pseudorandom sequences have good statistical properties as well as an advantage over one of the most popular generators at this point, the Mersenne Twister MT19937.

[A Case of Early Gastric Cancer with Multiple Lymph Node Metastases Revealed by Additional Surgical Resection after ESD].

A 74-year-old man was referred to our hospital for further investigation of a cystic lesion in the pancreatic body, which had been detected by ultrasonography at a local hospital. He was diagnosed as intraductal papillary mucinous neoplasm(IPMN) and further preoperative examinations were conducted. Upper gastrointestinal endoscopy demonstrated a type 0-II c tumor of the greater curvature in the upper third of the stomach. Endoscopic ultrasonography showed no sign of submucosal invasion. Endoscopic submucosal dissection(ESD)was carried out and pathological examination of a specimen revealed well differentiated adenocarcinoma with submucosal invasion, which fulfilled the indication for additional gastrectomy with lymph node dissection. Laparoscopy-assisted proxymal gastrectomy with D1 plus lymph node dissection and distal pancreatectomy with splenectomy was performed. Pathological examination demonstrated intraductal papillary mucious adenoma(IPMA)in the pancreatic body and no residual gastric cancer in a specimen, however 7lymph node metastases from gastric cancer was confirmed(pN3a), including 3 metastatic lymph nodes incidentally-detected adjacent to the pancreatic parenchyma. We report a rare case of early gastric cancer with N3 lymph node metastases, with a brief literature review.

[The Actual State of Treatment of Gastrointestinal Cancer with Abdominal Aortic Aneurysm in Our Department over the Past Five Years].

With the aging of the population of Japan and Westernization of the dietary life, the number of cases in which cardiovascular diseases are merged in non-cardiac surgery is increasing year by year.Many of the abdominal aortic aneurysms are asymptomatic and it is not uncommon to be discovered accidentally in preoperative examination of non-cardiac surgery.When gastrointestinal surgery involves malignant diseases of the gastrointestinal tract and abdominal aortic aneurysm, the two life prognosis-related diseases are merged, depending on the severity and urgency of the disease for each case, its treatment to determine the priority order.Abdominal aortic aneurysm occurred at the time of malignant disease surgery in 14 cases of gastrointestinal cancer patients who underwent surgery at the department during the 5 years from 2012 to 2016.T he actual condition of treatment for these cases was investigated.
