Samples of ultra-high-purity tungsten prepared using chemical vapour deposition(CVD)technique were irradiated with neutrons at temperatures T_(irr)=373-483 K(stage Ⅱ of defect recovery)and T_(irr)=573-673 K(stage Ⅲ)up to 0.15 displacements per atom(dpa)in the Belgian reactor(BR2).The study of the microstructure of neutron-damaged samples using transmission electron microscopy(TEM)revealed visible defects with a predominance of dislocation loops.With an increase in the neutron irradiation temperature,the spatial distribution of the loops acquired pronounced inhomogeneity,and their average size moderately increased.Cavities and voids were not observed.Irradiation-induced hardening was found and a linear correlation was obtained between Vickers microhardness and nanohardness for undamaged and neutron-irradiated CVD-W samples.Irradiation of tungsten with neutrons led to a significant increase in the retention of deuterium,which accumulated mainly in vacancy-type traps.Furthermore,the influence of the columnar grain structure in low-dose neutron-irradiated tungsten seemed to be non-trivial upon deuterium retention.

1933年间,北平相继出现了两种大型文学杂志《文学杂志》和《文艺月报》。体裁与内容相似的这两种公开杂志之间有何关系?关于《文学杂志》,据当时左联负责人员陆万美的证言,它被当做了北方左联的机关刊物。但朱正以王志之在其《鲁迅印象记》里所描写的该杂志发刊筹备的情况为证据,主张它不是左联机关刊物。我再三慎重斟酌两种杂志的内容以及两位论者的主张,最后得出了如下结论:与朱正的主张相反,我认为《文学杂志》的产生是北方左联在纠正"关门主义"的过程中所做的实践之一。但这个富有重要意义的尝试也被文总(即指导左联的上级机关)视为"右倾化"的产物而拒绝了。负责开展左联活动的潘漠华、陆万美等人受到批判,左联又改变了方向。《文艺月报》是在文总的指导下以北平社联的负责人员为中心创办的刊物,它是在推动北方左联全体走上"左倾"路线起了很大作用的一种杂志。

BACKGROUND Patients with intraductal papillary mucinous neoplasm(IPMN)have an increased risk of pancreatic and extrapancreatic malignancies.Lymphomas are rare extrapancreatic malignancies,and in situ collisions of early gastric cancer and diffuse large B-cell lymphoma(DLBCL)are even rarer.Here,we report the first case of pancreatic cancer comorbid with in situ collision of extrapancreatic malignancies(early gastric cancer and DLBCL)in a follow-up IPMN patient.Furthermore,we have made innovations in the treatment of such cases.CASE SUMMARY An 81-year-old Japanese female diagnosed with IPMN developed elevated carbohydrate antigen(CA)19-9 levels during follow-up.Because her CA19-9 levels continued to rise,endoscopic ultrasound(EUS)was performed and revealed a suspicious lesion at the pancreatic tail.However,lesions in the pancreas were not found by computed tomography,magnetic resonance imaging,or endoscopic retrograde cholangiopancreatography.To make an exact pathological diagnosis,EUS-guided fine needle aspiration was performed.To our supprise,early gastric cancer was found in preoperative gastroscopy.The gastric cancer was completely resected through endoscopic submucosal dissection before postoperative pathology identified early adenocarcinoma collided with DLBCL.Subsequent EUS-guided fine needle aspiration provided pathological support forthe pancreatic cancer diagnosis, and then laparoscopic distal pancreatectomy andsplenectomy were performed. CA19-9 levels returned to normal postoperatively.CONCLUSION Endoscopic submucosal dissection is appropriate for submucosal lymphomas inpatients intoleratant of chemotherapy. EUS can detect small IPMN-relatedpancreatic tumors.

BACKGROUND The presence of premalignant polyps on colonoscopy is an indicator of metachronous colorectal cancer.Looping during colonoscopy is associated with old age,female sex,and colonoscopy insertion time.However,the clinical significance of looping is not fully understood.We aimed to clarify the effect of looping on colorectal premalignant polyp detection.AIM To assess the effects of looping on premalignant polyp detection using logistic regression analyses.METHODS We retrospectively investigated patients who underwent colonoscopy at Toyoshima Endoscopy Clinic between May,2017 and October,2020.From the clinic’s endoscopy database,we extracted data on patient age,sex,endoscopist-assessed looping,colonoscopy duration,endoscopist experience,detection rate,and number of premalignant polyps.RESULTS We assessed 12259 patients(mean age,53.6 years;men,50.7%).Looping occurred in 54.3%of the patients.Mild and severe looping were noted in 4399 and 2253 patients,respectively.The detection rates of adenomas,advanced adenomas,high-risk adenomas,clinically significant serrated polyps(CSSPs),and sessile serrated lesions(SSLs)were 44.7%,2.0%,9.9%,8.9%and 3.5%,respectively.The mean numbers of adenomas and SSLs were 0.82 and 0.04,respectively.The detection rates of adenomas,high-risk adenomas,and CSSPs increased with looping severity(all P<0.001).The number of adenomas increased with looping severity(P<0.001).Multivariate analyses found that detection of adenomas,high-risk adenomas,and CSSPs was associated with severe looping(P<0.001,P<0.001,and P=0.007,respectively)regardless of age,sex,time required for colonoscope insertion and withdrawal,and endoscopist experience.CONCLUSION Looping severity was independently associated with high detection rates of premalignant polyps.Therefore,looping may predict the risk of metachronous colorectal cancer.Endoscopists should carefully examine the colorectum of patients with looping.

In order to see whether carbon ion (C-ion) beams have a biological advantage over X-rays, studies were designed to examine the effects of C-ion beams on radiosensitivity in X-ray resistant cells. Clinically relevant X-ray resistant SAS-R cells derived from human tongue cancer SAS cells were used. The cells were exposed to X-rays or Spread-Out Bragg peak (SOBP) beam C-ions. Cell survival was measured using a modified high-density survival assay. Cell survival signaling and cell death signaling were analyzed using flow cytometry. The cells were labeled with putative cancer stem cell markers such as CD44 and CD326. SAS-R cells were 1.6 times more radioresistant than SAS cells after exposure to X-rays. Cell survival was similar in each cell line after exposure to C-ion beams. SAS-R cells displayed enhanced cell survival signaling when compared to SAS cells under normal conditions. On the other hand, the phosphorylation of AKT-related proteins decreased and polycaspase activities were enhanced when cells were irradiated with C-ion beams in both cell lines. More CD44 and CD326 positive cells were seen in SAS-R cells than in SAS cells. Moreover, the marker positive cell numbers significantly decreased after exposure to C-ion beams when compared to X-rays at iso-survival doses in SAS-R cells. C-ion beams efficiently induced cell killing in X-ray resistant cells which displayed activated cell survival signaling and contained more numerous cancer stem-like cells.

AIM To elucidate the factors associated with residual gastroesophageal reflux disease(GERD) symptoms in patients receiving proton pump inhibitor(PPI) maintenance therapy in clinical practice.METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD(FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale(GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed.RESULTS The FSSG scores ranged from 1 to 28 points(median score: 7.5 points), and 19 patients(48.7%) had a score of 8 points or more. The patients' GSRS scores were significantly correlated with their FSSG scores(correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers(RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers(total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients(total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.

BACKGROUND Accurate diagnosis of the depth of gastric cancer invasion is crucial in clinical practice.The diagnosis of gastric cancer depth is often made using endoscopic characteristics of the tumor and its margins;however,evaluating invasion depth based on endoscopic background gastritis remains unclear.AIM To investigate predicting submucosal invasion using the endoscopy-based Kyoto classification of gastritis.METHODS Patients with gastric cancer detected on esophagogastroduodenoscopy at Toyoshima Endoscopy Clinic were enrolled.We analyzed the effects of patient and tumor characteristics,including age,sex,body mass index,surveillance endoscopy within 2 years,current Helicobacter pylori infection,the Kyoto classification,and Lauren’s tumor type,on submucosal tumor invasion and curative endoscopic resection.The Kyoto classification included atrophy,intestinal metaplasia,enlarged folds,nodularity,and diffuse redness.Atrophy was characterized by non-reddish and low mucosa.Intestinal metaplasia was detected as patchy whitish or grayish-white flat elevations,forming an irregular uneven surface.An enlarged fold referred to a fold width≥5 mm in the greater curvature of the corpus.Nodularity was characterized by goosebump-like multiple nodules in the antrum.Diffuse redness was characterized by uniform reddish nonatrophic mucosa in the greater curvature of the corpus.RESULTS A total of 266 gastric cancer patients(mean age,66.7 years;male sex,58.6%;mean body mass index,22.8 kg/m2)were enrolled.Ninety-three patients underwent esophagogastroduodenoscopy for surveillance within 2 years,and 140 had current Helicobacter pylori infection.The mean Kyoto score was 4.54.Fifty-eight cancers were diffuse-type,and 87 cancers had invaded the submucosa.Multivariate analysis revealed that low body mass index(odds ratio 0.88,P=0.02),no surveillance esophagogastroduodenoscopy within 2 years(odds ratio 0.15,P<0.001),endoscopic enlarged folds of gastritis(odds ratio 3.39,P=0.001),and Lauren’s diffuse-type(odds ratio 5.09,P<0.001)were indep

In response to environmental variation, angiosperm trees bend their stems by forming tension wood, which consists of a cellulose-rich G （gelatinous）-Iayer in the walls of fiber cells and generates abnormal tensile stress in the secondary xylem. We produced transgenic poplar plants overexpressing several endoglycanases to reduce each specific polysaccharide in the cell wall, as the secondary xylem consists of primary and secondary wall layers. When placed horizontally, the basal regions of stems of transgenic poplars overexpressing xyloglucanase alone could not bend upward due to low strain in the tension side of the xylem. In the wild-type plants, xyloglucan was found in the inner surface of G-layers during multiple layering. In situ xyloglucan endotransglucosylase （XET） activity showed that the incorporation of whole xyloglucan, potentially for wall tightening, began at the inner surface layers S1 and S2 and was retained throughout G-layer development, while the incorporation of xyloglucan heptasaccharide （XXXG） for wall loosening occurred in the primary wall of the expanding zone. We propose that the xyloglucan network is reinforced by XET to form a further connection between wall-bound and secreted xyloglucans in order to withstand the tensile stress created within the cellulose G-layer micro fibrils.
