However, the roles of Mo-LCs in the pathogenesis of psoriasis in humans remain unclear. Also, the contribution of notch ligand delta-like 1 (DLL-1), expressed on keratinocytes, to Mo-LC functions requires clarification. Here, we established a new method of stimulating Mo-LCs derived from CD14+ monocytes with immobilized human DLL-1 to generate induced Mo-LCs (DI (+)Mo-LCs). The DI (+) Mo-LCs were compared to the dendritic cells derived from monocytes (Mo-DCs) cultured with interleukin-4 (IL-4) and granulocyte-macrophage colony-stimulating factor (GM-CSF), and M1 macrophages (Mφ) derived from monocytes cultured with GM-CSF. The DI (+)Mo-LCs were found to produce significant amounts of IL15, IL23A, and interferon-β (IFNB1) in response to the Toll-like receptor (TLR)3 agonist Polyinosinic-polycytidylic acid (Poly (I:C)) or TLR4 agonist lipopolysaccharide (LPS) despite their low expression of tumor necrosis factor (TNF). In conclusion, we have established a new method to generate DI (+)Mo-LCs. We have also discovered that DI (+)Mo-LCs have a unique capacity for producing IL15 and IL23A, which are related to the pathogenesis of psoriasis. Our data contribute to a better understanding of the roles of Mo-LCs in epidermal defense and pathogenesis.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"91 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80870422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of the symptomatic RCCs, those that rapidly develop and cause hemorrhagic RCC apoplexy are particularly rare. In this study, we report a case of nonhemorrhagic RCC apoplexy that is an acute-onset RCC without intracystic hemorrhage. This study included a 21-year-old male patient. His chief complaints were severe headache with sudden disturbance of consciousness, visual disturbance, and double vision. Head computed tomography (CT)/magnetic resonance imaging (MRI) and clinical course indicated a hemorrhagic RCC apoplexy that is an acute-onset RCC with intracystic hemorrhage, a nonhemorrhagic RCC apoplexy, or a pituitary apoplexy. We then performed endoscopic transsphenoidal surgery. Histopathological examinations revealed a nonhemorrhagic RCC apoplexy. The preoperative diagnosis makes it difficult to distinguish between acuteonset hemorrhagic RCC apoplexy, nonhemorrhagic RCC apoplexy, and pituitary apoplexy. We compared 26 cases of hemorrhagic RCC apoplexy with cases of nonhemorrhagic RCC apoplexy by reviewing previous literatures. Furthermore, we have determined the characteristics of nonhemorrhagic RCC apoplexy. Knowledge on these characteristics may be useful in the differential diagnosis. For the differential diagnosis and treatment of RCC apoplexy and pituitary apoplexy, it is important to appropriately perform surgical treatment and make an accurate diagnosis based on surgical and pathological findings.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80961341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CFD analysisʼs ability to detect obstruction was comparable to that of RM and AR; therefore, it may help evaluate the upper airways in patients with nasal and paranasal diseases.

It is treated with various surgical methods to treat upper cervical problems, including atlantoaxial fusion, occipitocervical fusion, and C1 laminectomy. However, the choice of surgical method, especially in highly aged (≥ 80 years) patients, is controversial. This case report describes the difficulty of selecting the appropriate surgical procedure for upper cervical and occipitocervical diseases in highly aged patients. An 85-yearold woman complained of neck pain and bilateral hand numbness. The Japanese Orthopedic Association score for cervical myelopathy (C-JOA) of the patient was 9 out of a possible score of 17. Plain radiographs showed atlantoaxial subluxation (AAS) and vertical subluxation (VS), whereas magnetic resonance imaging showed spinal cord compression and myelomalacia at C1-2. The patient underwent a C1 laminectomy to minimize invasive procedures. After surgery, her symptoms improved, and her C-JOA score increased to 12. Fifteen months after surgery, her neurological conditions gradually deteriorated again. Her VS progressed postoperatively, with spinal canal restenosis at the craniovertebral junction. After an additional occipitocervical fusion, her symptoms improved, and she had no evidence of recurrence at her final follow-up. Although surgeons tend to choose less-invasive procedures when treating highly aged patients, appropriate surgical procedures may be required (even if invasive for the patient) when less-invasive treatments failed. Hence, it is important to avoid over-selecting less-invasive surgical procedures for highly aged patients.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90656309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of fluoridation is likely based on the chemical properties of fluoridized hydroxyapatite; however, nanoscale tiny hydroxyapatite crystals in tooth enamel make it difficult to observe the demineralization pattern of fluoridated enamel versus the untreated enamel at a single crystal level. The purpose of this study was to mimic the demineralization patterns of fluoridated and untreated enamel by means of the newly developed hydrothermally enlarged enamel-like hydroxyapatite single crystals at Showa University. Largescale hydroxyapatite single crystals were hydrothermally produced from polyphosphoric acid and calcium oxide. The crystals were stored in sodium fluoride solutions with four different concentrations for 30 days, then exposed to 3% citric acid solution for up to 60 min. The degradation patterns of each sample were observed using a conventional scanning electron microscope and were analyzed using F K-edge X-ray absorption near edge structure spectra. The surfaces of the hydroxyapatite crystals treated by relatively low concentrations of fluoride showed degradation in citric acid as well as in the untreated control. The hydroxyapatite crystals treated with 1,500 and 9,000 ppm F revealed that the fluoridated outer pillar of the crystals remained mostly intact which made calcium fluoride detectable. Fluoridization of tooth enamel might be preventive of an early acid erosion at a crystal level with a caution of sufficient fluoride concentration and exposure over time. The remaining substantial portion of the crystal pillar implies of highly fluoridized crystals, and a possible remineralization occurs as long as saliva provides minerals required for enamel remineralization by in vivo regulation.","PeriodicalId":23019,"journal":{"name":"The Showa University Journal of Medical Sciences","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72904340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
