Self‐ordering of the cell arrangement porous structure anodic alumina has been studied in a sulfuric acid solution. Ordering was dependent on applied potential, and highly ordered obtained under anodization at constant potential 25 to 27 V. proceeded with growth oxide layer an appropriate film almost ideal hexagonal honeycomb formed over area several micrometers after long period anodization.
The controlling factor of self-ordering anodic porous alumina was investigated by focusing on the current density during film growth. homogeneity cell size improved with increasing formation voltage accompanied exponential increase in density. maximum anodizing for proceeding uniform oxide growth while avoiding extremely high gas evolution identical previously established voltage. With up to voltage, ratio pore diameter lowered and converged ∼0.3 regardless electrolyte type. Moreover,...
Oxide films formed naturally on pure Mg are investigated by the use of ultramicrotomed cross sections and transmission electron microscopy. The film in air immediately after scratching metal surface is initially thin, dense, amorphous, relatively dehydrated. Continuing exposure to humid or water leads formation a thicker hydrated adjacent metal. contains an additional top layer characterized plateletlike morphology. structure these layers their significance corrosion protection discussed....
Abstract Background Improving patients' oral hygiene is an option for preventing postoperative pneumonia that may be caused by aspiration of and pharyngeal secretions. Whether preoperative care a dentist can decrease complications remains controversial. A retrospective cohort study was undertaken to assess the association between among patients who underwent major cancer surgery. Methods The nationwide administrative claims database in Japan analysed. Patients were identified resection head...
Myxedema coma is a life-threatening and emergency presentation of hypothyroidism. However, the clinical features outcomes this condition have been poorly defined because its rarity.We conducted retrospective observational study patients diagnosed with myxedema from July 2010 through March 2013 using national inpatient database in Japan. We investigated characteristics, comorbidities, treatments, in-hospital mortality coma.We identified 149 out approximately 19 million inpatients database....
Resolvin E1 (RvE1) is a lipid mediator derived from ω3 polyunsaturated fatty acids that exerts potent antiinflammatory roles in several murine models. The mechanism of RvE1 acquired immune responses has been attributed to attenuation cytokine production by dendritic cells (DCs). In this study, we newly investigated the effect on DC motility using two-photon microscopy contact hypersensitivity (CHS) model and found impaired skin. addition, attenuated T cell priming draining lymph nodes...
Morphology and structure of oxide films formed naturally on magnesium‐aluminum alloys by exposure to humid air water have been investigated use ultramicrotomed cross sections transmission electron microscopy compared the properties pure magnesium. Similar magnesium, initial air‐formed film is amorphous dense. The in has a three‐layered consisting hydrated inner layer, dense intermediate layer similar film, top with platelet‐like morphology. With increasing aluminum content alloy, all layers...
Oxides on ternary magnesium alloys MgAlZn and MgAlRE were investigated by transmission electron microscopy using ultramicrotomed film sections. These films have a three‐layered structure, similar to pure Mg binary MgAl allows characterized hydrated inner layer, thin dense intermediate region, platelet‐like outer layer. Zinc rare‐earth elements present in the two types of become incorporated oxide so as increase its stability an aqueous environment, particular reducing hydration increasing...
The self-ordering behavior of porous anodic alumina induced by the burning phenomenon on specimen where extremely high and local current concentrations occurred was studied. domains highly self-ordered cell arrangement were found at locally thickened film formed burning. At center burnt area, regularity higher barrier layer thickness as well size remarkably lower. These results clearly suggest that condition inducing growth under density, i.e., electric field is key factor determining...
Cutaneous angiosarcoma (CAS) is a malignant sarcoma with poor prognosis. Programmed cell death-1 (PD-1)/programmed ligand-1 (PD-L1) expression reflects antitumor immunity, and associated patient prognosis in various cancers. The purpose of this study to investigate the relationship between PD-1/PD-L1 CAS cases (n = 106) were immunohistochemically studied for PD-L1 PD-1 expression, correlation was analyzed. assessed by flow cytometry on three lines or without IFNγ stimulation. A total 30.2%...
Abstract Background Direct comparative effectiveness of booster doses BNT162b2 and mRNA-1273 after primary vaccination is unknown. Methods We investigated dose using data from registry systems for coronavirus disease 2019 (COVID-19) infection in a local city Japan. followed participants aged ≥16 years who completed the between 22 November 2021, 15 April 2022. collected information on age, sex, status, vaccine type, status. Age was categorized as 16–44, 45–64, 65–84, ≥85 years. Vaccine no...
This study aimed to elucidate the impact of periodontal therapy on glycaemic control in individuals with type 2 diabetes and various baseline blood glucose levels using a large-scale claims database from Japan.
Nanoporous and single phase α-alumina membranes with pore diameters tunable over a wide range of approximately 60-350 nm were successfully fabricated by optimizing the conditions for anodizing, subsequent detachment, heat treatment. The diameter increased cell shrunk upon crystallization to 20% 3%, respectively, in accordance 23% volume shrinkage resulting from change density associated transformation amorphous state α-alumina. Nevertheless, flat membranes, each 25 mm thickness 50 μm,...
ABSTRACT Purpose To assess adverse neurological risks following influenza vaccination in older adults. Methods Using a linked database of healthcare administrative claims data and records from an urban city Japan (April 1, 2014, to March 31, 2020), we conducted observational study utilizing self‐controlled case series design. We identified individuals aged ≥ 65 years who experienced outcomes, defined as hospitalizations related epilepsy, paralysis, facial neuralgia, neuritis, optic migraine,...
