BACKGROUND Staphylococcus aureus is one of the major causes of community-acquired and hospital-acquired infections. It produces numerous toxins including superantigens that cause unique disease entities such as toxic-shock syndrome and staphylococcal scarlet fever, and has acquired resistance to practically all antibiotics. Whole genome analysis is a(More)
In virtually all eukaryotes, mitosis starts after the completion of DNA synthesis. This orderly process is ensured by the checkpoint mechanism that blocks the onset of mitosis while DNA is being synthesized or is damaged. In the fission yeast Schizosaccharomyces pombe, this mechanism involves some rad+ and hus+ genes. However, it is not known how the(More)
Sister chromatid cohesion is essential for cell viability. We have isolated a novel temperature-sensitive lethal mutant named eso1-H17 that displays spindle assembly checkpoint-dependent mitotic delay and abnormal chromosome segregation. At the permissive temperature, the eso1-H17 mutant shows mild sensitivity to UV irradiation and DNA-damaging chemicals.(More)
OBJECT The prognosis in patients with a distant spinal metastasis from the lung is dismal. The role of radical surgery in such cases has been questioned because of the excessive morbidity, blood loss, and operative time as well as the tumor's extreme malignancy. The purpose of this study was to evaluate the surgical results and the prognosis associated with(More)
The following are the clinical and autopsy findings in a 63-year-old woman with myelopathy associated with the human T-cell lymphotropic virus Type I (HTLV-I). HTLV-I antibody was positive in both the serum and cerebrospinal fluid (CSF). In the lower thoracic region, demyelination and the loss of axons were accompanied by a proliferation of astrocytes, and(More)
BACKGROUND To assess the efficacy and safety of S-1 and cisplatin with concurrent thoracic radiation for unresectable stage III non-small-cell lung cancer (NSCLC). METHODS Eligible patients were 20-74 years old and had histologically or cytologically confirmed NSCLC, a performance status of 0-1, and no prior chemotherapy. Patients were treated with(More)
A biomechanical study of an interspinous stabilization spinal implant (Coflex) was carried out using eight human lumbar L4/L5 motion segments. Each motion segment was tested in compression, then flexion/extension, then lateral bending, and then axial rotation at five conditions: 1) intact; 2) partial destabilization (by cutting the supraspinous and(More)
surgical techniques. A review of the developmental process of this operation leads to recognition of the tips, pitfalls, and solutions. We review here the principal concepts of TES for spinal tumors, as well as their related basic works that support the rationality of this operation. 1. Oncologic concept of spinal tumors (compartment and barriers) Enneking(More)
Since 1990, early surgery within 3 days following subarachnoid hemorrhage has been performed routinely in our hospital even for ruptured posterior circulation aneurysms. Our experience with early surgical management of 25 patients with posterior circulation aneurysms, including two patients who underwent endovascular surgery, is reported. Fourteen patients(More)
BACKGROUND Vertebral artery dissection lesions tend to resolve spontaneously, but abnormal findings such as aneurysmal-dilatation occasionally persist. However, the clinical features and pathological findings in such cases have never been verified. CASE DESCRIPTION A 62-year-old man presented with left cerebellar infarction. Angiography showed the "pearl(More)
