    Abstract Zebrafish models have been developed for several studies involving lipid metabolism and lipid-related diseases. In the present study, the migration of dietary docosahexaenoic acid (DHA) in whole-body zebrafish was estimated by stable-isotope tracer and matrix-assisted laser desorption/ionization mass spectrometry imaging. Administration of 1-¹³C-2,2-D₂-labeled DHA ((+3)DHA) ethyl ester to male zebrafish was conducted to evaluate its accumulation, migration, and distribution in the body. The (+3)DHA content in the body of zebrafish after administering (+3)DHA for 10 and 15 d was significantly higher than that in the control group. (+3)DHA was observed as a constituent of phosphatidylcholine (PC) in the intestine of zebrafish that were administered (+3)DHA for 5 and 10 d. (+3)DHA-containing PC tended to accumulate in the intestines of zebrafish administered (+3)DHA for 1 d, indicating that recombination of (+3)DHA from ethyl ester to PC occurs quickly at intestine. After administration for 15 d, (+3)DHA-containing PC accumulated in the intestine, liver, and muscle of whole-body zebrafish. In contrast, (+3)DHA-containing PC was not detected in the brain. These results showed that dietary DHA is initially constructed into PC as a structural component of intestinal cell membranes and gradually migrates into peripheral tissues such as muscle.

    Abstract Ni-enriched layered materials are utilized as positive electrode materials of high-energy Li-ion batteries. Because electrode reversibility is gradually lost for stoichiometric LiNiO₂ after continuous cycles, Ni ions are partially substituted by other metal ions (Co, Mn, Al etc.). However, the origin of deterioration in stoichiometric LiNiO₂ is still not fully understand yet. Moreover, the loss of capacities is observed only in the high voltage region (>4.1 V), which is obviously different from the failure mode observed in other electrode materials. Here, we report for the first time the origin of deterioration, which is revealed by an in situ X-ray diffraction study. For fully charged NiO₂, Ni ions migrate from original octahedral sites in NiO₂ slabs to face-sharing tetrahedral sites in Li layers, by which the O3 to O1 phase transition is suppresed. Note that Ni migration is a reversible process, and the Ni ions migrate back to the original octahedral sites on discharge. However, after continuous cycles, the reversibility of Ni migration is gradually lost, and Ni ions are partially left at the tetrahedral sites in Li layers. Electrode kinetics are also deteriorated because of the Ni occupation in Li layers, and the accumulation of Ni ions at tetrahedral sites results in the loss of reversible capacities in the high voltage region. This finding opens a new way to design high-capacity Ni-enriched electrode materials, leading to the development of high-energy Li-ion batteries.

    Abstract We developed a new method for monitoring the distribution of administrated fatty acids in the body by combination of a stable isotope-labeling technique and imaging mass spectrometry (IMS). The developed stable isotope-labeling technique is very simple and able to adapt to all the fatty acid species. In this study, we synthesized stable isotope-labeled arachidonic acid (AA) and docosahexaenoic acid (DHA), and they were simultaneously administrated to mice to examine their migrations and distributions in the brain. The administrated AA and DHA have two more molecular weights compared to the originals and apparently were distinguished from the originally accumulated AA and DHA in the brain using IMS. As a result, we reveal that the administered AA and DHA first accumulated in the hippocampus and cerebellar cortex in the brain. This technique does not use radio isotopes and would appear to elucidate the role of all kinds of fatty acid species in the body.

    Abstract We experienced six cases with eosinophilic esophagitis (EoE). They complained of dysphagia, heartburn, or retrosternal discomfort. Endoscopy revealed typical findings of EoE and biopsy examination showed significant eosinophil infiltration in the esophageal epithelium. They received sublingual immunotherapy (SLIT) for allergic rhinitis. Discontinuation or spit method during SLIT resulted in improvement of symptoms, and endoscopic and histological remission. Previously six cases with SLIT-induced EoE has been reported. Our case series suggest that SLIT is clearly associated with the development of EoE by entering of aeroallergens from the luminal side of the esophagus and spit method during SLIT might be one of the therapeutic options for SLIT-induced EoE.

    Abstract The patient was a woman in her 70's was referred to our hospital because of an abnormal shadow on chest roentgenogram at an annual medical checkup. Since preoperative examinations suggested lung cancer in the right middle lobe, thoracoscopic right middle lobectomy was planned. However, pleural dissemination was detected at surgery and we changed the treatment plan to the intrapleural hyperthermic chemotherapy. During the postoperative course, facial edema, hypokalemia, and hyperglycemia developed, and the diagnosis of Cushing's syndrome was suggested based on an increase in serum level of adrenocorticotropic hormone (ACTH) and cortisol, and was confirmed by a dexamethasone suppression test. Intrapleural hyperthermic chemotherapy was likely to collapse the ACTH-producing tumor leading Cushing's syndrome.

    Abstract Pulmonary dirofilariasis is an infection caused by Dirofilaria immitis, which is an endemic parasite in Japan. We experienced 13 surgical cases of pulmonary dirofilariasis in our hospital. Of the 13 patients, 61.5% were men. The responsible lesions were located in the right lung in all cases, and 76.9% of them were in the lower lobe. Histologically, 12 cases showed necrotic nodules with peripheral granuloma with worms inside the pulmonary artery. One case did not show a necrotic nodule but showed only thickening and hyalinization of the pulmonary artery wall with a degenerated worm inside. Eosinophils were found histologically in all cases. Thirteen cases of dirofilariasis in one institution seem to be the largest number in Japan, based on previous reports. One reason for this increased prevalence may be the hot and humid climate of our prefecture considering the ecology of the mosquito as a vector. Elastic staining and eosinophils in peripheral granulomatous areas can contribute to the diagnosis when the worms are degenerated.

    Abstract Background: Cardiovascular surgery in older patients with sarcopenia has high rates of major complications, long hospital stays, readmissions, and discharge transfers. However, the factors that influence the length of hospital stay are unknown. This study aimed was to identify the predictors of the prolonged hospital stay in patients with sarcopenia after cardiovascular surgery.
    Methods: A total of 192 patients scheduled for cardiac surgery were enrolled in this retrospective observational study. Sarcopenia was diagnosed preoperatively. Clinical data from the preoperative, intraoperative, and perioperative periods were evaluated to determine the factors influencing the length of hospital stay.
    Results: The sarcopenia and non-sarcopenia groups differed significantly in age; body mass index; renal function; intubation time; transfusion of red blood cells; hospital transfer; and hemoglobin, brain natriuretic peptide, and albumin levels. Sarcopenia was the most significant factor influencing prolonged postoperative hospital stay, as well as prolonged intubation time. In the sarcopenia group, albumin levels and cardiopulmonary bypass time were the significant factors affecting hospital stay.
    Conclusions: Sarcopenia was the most significant factor associated with prolonged postoperative hospital stay in patients who underwent cardiac surgery. In addition, improving sarcopenia, nutritional status, and shortening cardiopulmonary bypass time appear to shorten the hospital stay in patients with sarcopenia who underwent cardiovascular surgery.

    Abstract Introduction: Bronchogenic cysts may rupture or become infected, and malignant degeneration may occur. Although various types of malignant degeneration have been described, only a few reports of mucoepidermoid carcinoma arising from a bronchogenic cyst have been published. We report such a case.
    Case: A 77-year-old female was referred to our institution for evaluation of left chest pain. A computed tomography scan showed an enhancing 65 × 70 mm mass of the left diaphragm. Based on the intraoperative findings of an intradiaphragmatic tumor involving the lower lobe of the left lung, the resection of the tumor with the wedge resection of left lower lobe and partial resection of the left diaphragm was performed. Histopathologic examination revealed a mucoepidermoid carcinoma arising from a bronchogenic cyst of the diaphragm with the presence of fibrous adhesion to the lower lobe.
    Conclusion: We believe that complete resection of any bronchogenic cyst is justified.
