The microvascular architecture of the human cerebral subcortical white matter was studied. Most of the subcortical arteries ran straight through the cortex, but upon entering the white matter, they began to coil, loop, and spiral. Vascular stains showed wide spaces between the adventitial sheaths and blood vessels. The blood vessels coiled, looped, and(More)
The vascular architecture of the human cerebral deep white matter was studied using soft X-ray and diaphanized specimens, achieved by intra-arterial injection of barium and vascular stain respectively, and also by electron microscopic examination of the corrosion cast of arteries in normal adult brains. The deep white matter arteries passed through the(More)
In the present study, the human cerebral meninges were rich in blood vessels, but no capillaries were noted. The meningeal arteries ran over the veins where they crossed. Several arterial anastomoses existed on the cortical surface. The meningeal arteries were classified into four parts; the conducting artery approximately 700 microm in diameter,(More)
The vascular architecture of the human cerebellar meninges was investigated. The surface meninges were poor in vasculature. In the sulci, the meninges were highly vascular but had few capillaries. The venous blood vessels gave long side branches at right angles to the parent vessels in a cruciform pattern, running horizontally along the cerebellar sulci.(More)
Myeloid-derived suppressor cells (MDSC) are a heterogeneous population of immature and progenitor myeloid cells with an immunosuppressive role in various types of cancer, including head and neck squamous cell carcinoma (HNSCC). However, the effect on the host immune system, especially on invariant NKT (iNKT) cells with potent anti-tumor activity, remains(More)
AIMS   To review the histopathological features of cervical LNs, and to clarify the changes in extracervical LNs, in acute Kawasaki disease (KD). METHODS AND RESULTS   The samples were obtained from 33 patients with acute-phase KD. We divided the LNs into those in the neck (n = 23) and those located elsewhere (n = 26), and investigated them(More)
We report a case of primary adenocarcinoma of the rete testis in a 55-year-old man with pulmonary metastases that were detected 11 months prior to the diagnosis of the primary lesion. Primary adenocarcinoma of the rete testis is an extremely rare malignant tumor with a poor outcome. The most common primary symptom is a scrotal mass, often accompanied by(More)
The role of invariant natural killer T (iNKT) cells in antitumor immunity has been studied extensively, and clinical trials in patients with advanced cancer have revealed a prolonged survival in some cases. In recent years, humanized blocking antibodies against co-stimulatory molecules such as PD-1 have been developed. The enhancement of T cell function is(More)
Tetanus develops following inoculation of damaged human tissue with Clostridium tetani which transforms into a vegetative rod-shaped bacterium and produces the tetanospasmin. Usually we make a diagnosis of tetanus based on typical symptoms and history of trauma. But, when patients have no noticeable history of trauma, we have to diagnose tetanus on the(More)
