Edutainment tools for initial education of type-1 diabetes mellitus: initial diabetes education with fun.

Purpose: Appropriate initial education for type-1 diabetes mellitus patients is important to prevent late complications. However, type-1 diabetic children have not appreciated traditional learning methods since they rarely contain the elements of fun and interactivity. In this study, we developed, implemented and evaluated a preliminary version of edutainment tools for initial education for type-1 diabetic children.

Selective expression and functional characteristics of three mammalian hyaluronan synthases in oncogenic malignant transformation.

Malignant transformation of fibroblasts and epithelial cells is often accompanied by increased hyaluronan production and accumulation. Despite recent progress in the study of hyaluronan biosynthesis, the mechanisms underlying the transformation-induced overproduction of hyaluronan have not been elucidated. Here we report that activity and transcriptional levels of hyaluronan synthase (HAS) significantly increased after oncogenic malignant transformation of a rat 3Y1 fibroblast cell line.

Apocrine carcinoma of the vulva in a band-like arrangement with inflammatory and telangiectatic metastasis via local lymphatic channels.

Background: Primary adenocarcinomas of the vulva have been classified as sweat gland carcinomas, extramammary Paget's disease, and primary breast carcinomas of the vulva. They share some common histopathologic features.

Methods: We describe a 72-year-old Japanese woman with apocrine carcinoma of the vulva and local lymphatic metastasis.

[A case of cutaneous tuberculosis under steroid & immunosuppressant therapy for dermatomyositis].

A 44-year-old man had been admitted for high fever and leg edema on November 1998. By the laboratory data, electromyography, and muscle biopsy, he was diagnosed as having polymyositis. Steroid (prednisolone 60 mg/day) and immunosuppressant (methotrexate 7.

Abnormal accumulation of hyaluronan matrix diminishes contact inhibition of cell growth and promotes cell migration.

Elevated hyaluronan biosynthesis and matrix deposition correlates with cell proliferation and migration. We ectopically expressed three isoforms of hyaluronan synthase (HAS1, HAS2, or HAS3) in nontransformed rat 3Y1 cells and observed a de novo, massive formation of a hyaluronan matrix that resulted in a partial loss of contact-mediated inhibition of cell growth and migration. All three HAS transfectants showed an enhanced motility in scratch wound assays, and a significant increase in their confluent cell densities.
