In recent years, various types of applications of electromagnetic techniques to microwave thermal therapies have been developed. The authors have been studying the coaxial-slot antenna, which is one of the thin microwave antennas, for the minimally invasive microwave thermal therapies, such as interstitial microwave hyperthermia. From the results of our(More)
Since the diversification of the electromagnetic (EM) environment is spreading, it is essential to estimate the EM energy absorption rate [specific absorption rate (SAR)] of a pregnant woman's body and her fetus under various exposure situations. This paper presents the EM dosimetry in a pregnant woman in proximity to a mobile-phone terminal using the(More)
The destruction of blood–brain barrier (BBB) and blood-nerve barrier (BNB) has been considered to be a key step in the disease process of a number of neurological disorders including cerebral ischemia, Alzheimer’s disease, multiple sclerosis, and diabetic neuropathy. Although glial cell line-derived neurotrophic factor (GDNF) and brain-derived neurotrophic(More)
Magnetic resonance imaging (MRI) is a noninvasive imaging techniques used to visualize the inside of the human body based on nuclear magnetic resonance. Currently, RF coils that transmit high frequency and high power of electromagnetic (EM) wave pulses are being investigated to obtain high-quality images and to shorten the imaging time. Due to these(More)
An axisymmetric model for the Crab Nebula is constructed to examine the flow dynamics in the nebula. The model is based on that of Kennel and Coro-niti (1984), although we assume that the kinetic-energy-dominant wind is confined in an equatorial region. The evolution of the distribution function of the electron-positron plasma flowing out in the neb-ula is(More)
OBJECTIVE In neuromyelitis optica (NMO), the destruction of the blood-brain barrier (BBB) has been considered to be the first step of the disease process. It is unclear whether sera from patients with NMO can open the BBB, and which component of patient sera is most important for this disruption. METHODS The effects of sera from antiaquaporin4 (AQP4)(More)
We previously showed that side population (SP) cells, characterized by specific Hoechst dye efflux pattern in flow cytometric analysis, were present in teleost kidney hematopoietic tissue, and that kidney SP cells were enriched in hematopoietic stem cells (HSCs). ABCG2/Abcg2 is an ATP-binding cassette (ABC) transporter that is known to be associated with(More)
Wireless power transmission is being investigated as a means to operate tiny medical equipments such as capsular endoscope that exists for a long time in the body. In this paper, we examine the wireless power transmission to a capsular endoscope by microwave as a new approach, in order to show its usability for medical applications. We propose power(More)
Schwannomas are rarely located in the pelvis. A 54-year-old woman was found incidentally to have a tumor in the abdomen. Abdominal computed tomography and magnetic resonance imaging revealed a well-defined, heterogeneous tumor, 5 cm in diameter, in the pelvic cavity. With a diagnosis of a mesenteric tumor, a laparoscopic procedure was performed.(More)
