Aging and aged societies have arrived in many countries where significant development of medicine and the economy has been achieved. Japan is a highly aged society with a shortage of carers both at home and in long-term care settings. In fact, more persons of advanced age who do not need intensive care in hospitals strongly desire health care to be delivered in their own home with their family. Environmental nursing practice, which means that nurses improve the environment of patients or the elderly properly in accordance with healthcare considerations, is currently playing a more important role, not only to prevent the elderly from contracting various diseases, but also to provide a facility for supporting an aged person to live a fulfilling life, preferably one that includes independence. This approach will lead to a reduction in medical expenditure by increasing the number of aged people with healthy longevity without the need for hospitalization or intensive care. This short communication focuses on healthy lighting for the elderly based on our research and experience regarding the beneficial effects of artificial sunlight on nonalcoholic steatohepatitis (NASH), asthma and food allergy, and ulcerative colitis in experimental animal models and clinical settings. Then, we review other studies and discuss how artificial sunlight would be useful for the elderly as one of the environmental nursing practices.

The reductive desorption of 2-aminoethanethiol (AET) monolayers formed on a polycrystalline gold electrode has been studied using cyclic voltammetry. Three cathodic peaks were observed and they were assigned to reductive desorption from each small domain of Au(111), (100), and (110) over the polycrystalline surface. The kinetics of adsorption were likely under the condition where the kinetic control and the diffusion control were balanced over the concentration range 5-50 μM (M = mol dm −3), whereas it was described by the kinetic control model at 100 μM. The thermodynamics of adsorption was well-described by the Langmuir isotherm. The saturation surface coverage was found to be 5.3 × 10 −10 mol cm −2 , which suggested that AET adsorbed lying flat on a polycrystalline gold electrode.

Perineurioma is a tumor that originates from the proliferation of perineurial-like cells and is classified into soft tissue perineurioma, which grows on the soft tissue rather than along the nerve, and intraneural perineurioma, which develops within the nerve. Perineurioma is uncommon, and reports of its occurrence in the oral cavity area are exceedingly rare. We describe our experience with a case of intraneural perineurioma derived from the inferior alveolar nerve that developed in the mandible and was resected by sagittal split ramus osteotomy. Here, we report a summary of our experience. A 41-year-old woman visited a clinic to undergo detailed examination of the radiolucent right mandibular ramus. A biopsy was performed, and a neural tumor was diagnosed. The tumor was resected by sagittal split ramus osteotomy with the patient under general anesthesia. Histopathological diagnosis of the resected specimen definitively identified the tumor to be intraneural perineurioma. Sagittal split ramus osteotomy was extremely effective for resection of the neural tumor derived from the inferior alveolar neurovascular bundle. Postoperatively, her occlusion is stable, and she has made satisfactory progress without recurrence as of 24 months after operation. : intraneural perineurioma (神経内神経周膜腫) ， inferior alveolar nerve (下歯槽神経) ， sagittal spit ramus osteotomy (下顎枝矢状分割法) 1) 独立行政法人国立病院機構東京医療センター歯科口腔外科 (主任：大鶴 洋医長) 2) 独立行政法人国立病院機構東京医療センター臨床検査科 (主任：白石淳一科長) 1)
