The Arrival Direction of EAS Observed by Kinki Array with Energy Around 10^<15> eV (II)

[Abstract] We have reported a seriese of asearch for the directional analysis of EAS for the Kinki data concerning on the galactic coordinates with energy range between 10^ and 10^eV at sea level. In this report, I will present some basic results about the distribution of arrival distribution of EAS in the galactic coordinates. No strong statistical significance of deviation from isotropy was found for the galactic plane enhancement. Concerning on the galactic enhancement tactor f_e a comparison with some other higher energy experiment is also presented

Total pancreatectomy with remnant stomach preservation in a patient with a history of proximal gastrectomy and interposed jejunal reconstruction with right gastroepiploic conduit preservation: a case report

Abstract Background Pancreatic head resection following proximal gastrectomy jeopardizes the blood flow of the remnant stomach owing to right gastroepiploic conduit sacrifice, thereby necessitating total gastrectomy. However, owing to its high invasiveness, concomitant remnant total gastrectomy with pancreatectomy should be avoided as much as possible. Herein, we describe our experience of total pancreatectomy with right gastroepiploic conduit preservation in a patient with a history of proximal gastrectomy and reconstruction by jejunum interposition. Case presentation A 78-year-old woman with a history of gastric cancer was followed up at our institute for multiple intraductal papillary mucinous neoplasm, and main pancreatic duct stricture in the pancreatic head was newly detected. The cystic lesion was extended to the pancreatic body. Proximal gastrectomy and reconstruction by jejunal interposition were previously performed, and the mesenteric stalk of the interposed jejunum was approached through the retrocolic route. We planned total pancreatectomy with right gastroepiploic conduit preservation. Following adhesiolysis, the interposed jejunum and its mesentery lying in front of the pancreas were isolated. The arterial arcade from the common hepatic artery to the right gastroepiploic artery was detached from the pancreas. Furthermore, the right gastroepiploic vein was isolated from the pancreas. The pancreatic body and tail were pulled up in front of the remnant stomach, and the splenic artery and vein were resected. The pancreatic body and tail were pulled out to the right side, and the pancreatic head was divided from the pancreatic nerve plexus to the portal vein. The jejunal limb for entero-biliary anastomosis was passed through the hole behind the superior mesenteric artery and vein, and gastrointestinal anastomosis using the antecolic route and Braun anastomosis were performed. Conclusions To avoid remnant total gastrectomy, right gastroepiploic conduit preservation is an optional procedure for pancreatic head resection in patients who have undergone proximal gastrectomy with reconstruction by jejunal interposition

Exploring the relationship between plasma substance P and glottal incompetence in the elderly

We speculated that increased blood-plasma levels of Substance P may serve as an indicator of glottal incompetence, which is usually indicated by reduced maximum phonation time. We performed an initial study to test the plausibility of this hypothesis. Patients with dysphonia caused by glottal incompetence were asked to perform vocal exercises for six months to reduce glottal incompetence and we compared the plasma concentration of Substance P before and after the vocal exercise to detect correlation between maximum phonation time and plasma concentration of Substance P. Based on the results, we further hypothesized that patients exhibiting dysphonia with maximum phonation time less than 14 s, in particular less than 10 sec, caused by glottal incompetence may have increased plasma concentration of Substance P with the results of elevated thresholds of cough reflex associated with subclinical aspiration in airways. Further study is needed on patients with decreased Substance P levels, with low scores on Activities of Daily Living and who are hospitalized with aspiration pneumonia

Intravenous infusion of auto-serum-expanded autologous mesenchymal stem cells into chronic severe brain injury patients

Objective: This study explores safety, feasibility, and potential improvement in functional status after intravenous infusion of mesenchymal stem cells (MSCs) in chronic severe brain injury (BI) patients. Methods: An intravenous infusion of autologous MSCs in autoserum cultured under Good Manufacturing Practice was delivered to four chronic patients with BI. In addition to assessing feasibility and safety, neurological function was evaluated using the National Institutes of Health Stroke Scale, Fugl-Meyer Assessment, Barthel Index, and cognitive-related behavioral assessment. Imaging studies with 18F-FDG-PETCT and 11C-methionine-PETCT (METPET) were carried out to evaluate brain metabolic activity. Results: No serious adverse events were recorded. None of the patients developed CNS tumors, abnormal cell growth, or neurological deterioration. While this initial case series was not blinded, gradual functional improvement was observed after MSC infusion. Serial 11C-METPETs displayed a statistically significant increase in methionine uptake, primarily in the thalamus and pons. Conclusion: We emphasize that this study was unblinded and did not exclude placebo effects, the contribution of endogenous recovery, or observer bias; however, our observations support feasibility and safety. No adverse events were observed. The data suggests improved quality of life after infused MSCs; however, a blinded, larger-scale study will be necessary to fully address this possibility
