Recent experimental studies have indicated that bone marrow stromal cells (BMSC) improve neurological deficits when transplanted into the animal models of various neurological disorders, although precise mechanism still remains unclear. In this study, we developed a new in vivo fluorescence optical imaging protocol to sequentially track the transplanted(More)
BACKGROUND Benign osteoblastoma is an uncommon primary bone tumor that usually affects long bones and the vertebral column. Its occurrence in the calvarium is rare. Despite the characteristically benign nomenclature of osteoblastoma, it sometimes recurs with the possibility of transforming into a malignant form after an incomplete resection. Therefore,(More)
There is increasing evidence that bone marrow stromal cells (BMSC) have the potential to migrate into the injured neural tissue and to differentiate into the CNS cells, indicating the possibility of autograft transplantation therapy. The present study was aimed to clarify whether the mouse BMSC can migrate into the lesion and differentiate into the CNS(More)
BACKGROUND In this study, we visualized the eloquent motor system including the somatosensory-motor cortex and corticospinal tract on a neuronavigation system, integrating magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), and anisotropic diffusion-weighted MRI (ADWI). METHODS Four patients with brain lesions adjacent to the(More)
Atypical teratoid/rhabdoid tumor (AT/RT) is a malignant tumor that mostly occurs in early childhood and has poor prognosis despite aggressive therapy. Adult cases are rare and, as far as we are aware, only 30 cases have been reported to date. Here we present the case of a 27-year-old female with left parietal AT/RT with the chief complaint of numbness of(More)
Bisphenol A (BPA), known as an environmental endocrine disrupter, is widely used in industry and dentistry. We investigated the effects of fetal and neonatal exposure to bisphenol A (BPA) on the brain development of mice. The density of tyrosine hydroxylase (TH)-immunoreactive (IR) neurons in substantia nigra was significantly decreased in BPA-exposed(More)
Recent experimental studies have shown that bone marrow stromal cells (BMSC) differentiate into neural cells and reduce neurological deficits when transplanted into traumatized spinal cord. These findings have been derived primarily from histological analyses. We conducted a study directed chiefly at developing a non-invasive system for tracking BMSC(More)
Chlamydia pneumoniae (C. pneumoniae) infection has been recently accepted as an important cause of atherosclerosis. However, the precise mechanisms remain unclear. The present study was aimed to clarify the distribution link among C. pneumoniae, chlamydial HSP 60, and activated macrophages. Atheromatous carotid plaques were obtained from 40 consecutive(More)
Recently, performances that combine performers' actions and images projected from a projector have attracted a great deal of attention. In such performances, since the performer usually faces the audience, it is difficult for him/her to watch the projected images on a background screen. This means that he/she cannot make the performances dynamic in response(More)
It has been reported that immunosuppressant FK506 inhibited ischemic neuronal injury in forebrain ischemia or transient focal cerebral ischemia, but the mechanisms of the neuroprotective effect have not been clarified. In permanent focal cerebral ischemia, we investigated whether FK506 caused remission of brain infarction, and how mechanism was concerned.(More)
