Transplantation of mesenchymal stem cells (MSCs) was reported to improve functional outcomes in a rat model of ischemic stroke, and subsequent studies suggest that MSC-derived microvesicles (MVs) can replace the beneficial effects of MSCs. Here, we evaluated three different MSC-derived MVs, including MVs from untreated MSCs (MSC-MVs), MVs from MSCs treated with normal rat brain extract (NBE-MSC-MVs), and MVs from MSCs treated with stroke-injured rat brain extract (SBE-MSC-MVs), and tested their

The generation of disease-specific induced pluripotent stem cell (iPSC) lines from patients with incurable diseases is a promising approach for studying disease mechanisms and drug screening. Such innovation enables to obtain autologous cell sources in regenerative medicine. Herein, we report the generation and characterization of iPSCs from fibroblasts of patients with sporadic or familial diseases, including Parkinson's disease (PD), Alzheimer's disease (AD), juvenile-onset, type I diabetes me

OBJECTIVES: To analyze the treatment outcomes and the effects of adjuvant radiotherapy (RT) in patients with synovial sarcoma (SS). MATERIALS AND METHODS: The medical records of 103 patients treated with definitive surgery for SS, with/without RT, from August 1982 to July 2013 were reviewed retrospectively. The median age of the patients was 33 years (range, 5 to 72 y). The most frequent tumor location was the extremities (79 patients, 77%). Seventy-five patients (73%) received adjuvant RT and 2

Eupatilin may act directly on pathogenic myofibroblasts, disarming them, whereas the anti-fibrotic effect of pirfenidone may be indirect. Eupatilin could increase the efficacy of IPF treatment to curative levels.

BACKGROUND: Extracellular matrix metalloproteinase inducer (EMMPRIN), a cell-surface glycoprotein, is overexpressed in several cancer types. EMMPRIN induces a metastatic phenotype by triggering the production of matrix metalloproteinase proteins (MMPs) such as MMP1 and MMP2, and vascular endothelial growth factor (VEGF) in cancer cells and the surrounding stromal cells. The purpose of this study was to investigate the expression and role of EMMPRIN in osteosarcoma. METHODS: The level of EMMPRIN

Mycobacterium other than tuberculosis infections rarely develop in healthy individuals, but direct inoculation such as contaminated acupuncture can cause mycobacteriosis even in an immunocompetent host. A 56-year-old woman gradually developed pain on the anterior aspect of the left knee and the distal thigh after hiking without trauma. She received acupuncture for 3 consecutive days on the bilateral knees at the suprapatellar and infrapopliteal areas. After acupuncture, mild localized heat and p

BACKGROUND: Cortical atrophy is commonly observed after prosthetic reconstruction for bone sarcomas. However, relevant literature regarding this phenomenon in skeletally immature patients is limited. Therefore, in this study, we evaluated the incidence and patterns of cortical atrophy. We then assessed its predisposing factors. Finally, we analyzed whether cortical atrophy was associated with poor prosthesis survival. METHODS: We retrospectively reviewed 31 stems in 19 skeletally immature osteos
