<h3>BACKGROUND AND PURPOSE:</h3> Blood flow in an intracranial stent cannot be visualized with 3D time-of-flight MR angiography owing to magnetic susceptibility and radiofrequency shielding. As a novel follow-up tool after stent-assisted coil embolization, we applied MRA by using Silent Scan algorithm that contains ultrashort TE combined arterial spin-labeling technique (Silent MRA). The purpose of this study was determine whether could visualize placed the anterior circulation....

It is common for neurotransmitters to possess multiple receptors that couple the same intracellular signaling molecules. This study analyzes two highly homologous G-protein-coupled octopamine using model animal Caenorhabditis elegans. In C. elegans, amine neurotransmitter induces activation of cAMP response element-binding protein (CREB) in cholinergic SIA neurons absence food through Gq-coupled receptor SER-3 these neurons. We also analyzed another receptor, SER-6, SER-3. As seen ser-3...

The aim of this research was to clarify the relation between screening rates for five cancers (lung cancer, stomach colorectal uterus and breast cancer) their mortality rate by using publicly accessible databases. used information materials were those prepared Ministry Health, Labour Welfare, Center Cancer Control Information Services, National Center. Our results as follows: 1) regarding cancers, a positive correlation found (p<0.001); 2) in according administrative divisions, decreased...

The Japanese have had three experiences of radiation disasters: the atomic bombs dropped on Hiroshima and Nagasaki in 1945, 2011 Fukushima Nuclear Power Plant disaster. former two been covered compulsory education programs. In light these incidents, a strong fear has pervaded people several generations. such situation, role nurses is important. When treat residents, their attitudes change depending how they understand feel about radiation. foundations are formed through student education....

In dentistry, panoramic radiography is an important examination technique. The Faculty of Dentistry at Tokushima University educates students about radiographic anatomical landmarks. purpose this study was to investigate differences in the understanding each landmark among students.This analyzed results 40 fifth- and 79 sixth-year faculty who had taken a written clarify their knowledge landmarks 28 regions. Anatomical were classified into 3 categories: <bone structure>, <soft tissue/air...

The relative biological effectiveness (RBE) of densely ionizing radiation can depend on the context. From a radiological perspective, age is an important factor affecting health risks exposure, but little known about modifying impact effects radiation. Herein, we addressed influence leukemogenesis induced by accelerator-generated fast neutrons (mean energy, ∼2 MeV). Male C3H/HeNrs mice were exposed to 137Cs γ rays (0.2-3.0 Gy) or (0.0485-0.97 Gy, ray contamination 0.0105-0.21 at 1, 3, 8, 35...

A new rat mutant showing aspermia was investigated. Groups of 4-7 male rats were killed at 3, 5, 10, 15 and 25 weeks age. Examination by microscope showed apparent abnormalities in the seminiferous epithelium from 3 age onward. Inclusion-like bodies observed cytoplasm pachytene spermatocytes old instead spermiation, polynuclear giant cells formed within after 5 Histological analysis adult also a marked decrease number preleptotene, leptotene tubules containing only spermatogonia Sertoli...

The purpose is to evaluate the performance of current intraoral digital detectors in detail using a precise phantom and new method. Two aluminum step wedges 0.5 mm steps were exposed by two photostimulable phosphor plate (PSP) systems-one with automatic exposure compensation (AEC) other without AEC-and CCD sensor. Images obtained 3 doses at 60 kV. effect metallic material also was evaluated. contrast-to-noise ratio (CNR) for thinner low contrast value (LCV) thicker obtained. system best...

Although the accumulation and distribution of metals from metallic orthodontic appliances in oral mucosa have been studied extensively, they remain unclear because their concentration is quite low. In this study, metal specimens (Ni, Ni-Ti, Co-Cr) were sutured unilateral rats, eluted elements mucosal tissue was estimated using inductively coupled plasma mass spectrometry (ICP-MS) synchrotron radiation X-ray fluorescence analysis (SR-XRF). While infiltrations Ni, Co, Cr into connective...

The light-addressable potentiometric sensor (LAPS) was combined with an enzyme reactor in a fluidic channel. channel mounted on the plate and connected to filled glass beads as carrier modified by urease which catalyzed production of ammonia depending concentration urea. Double-channel LAPS measurement performed at both side upper lower stream realized differential eliminated drift component measurement.

A newly identified aspermia rat mutant was investigated on testicular histology and mode of inheritance the defect. Average testis weight mutants about one-third that phenotypically normal males. Spermatogenesis interrupted at meiosis. Pachytene spermatocytes significantly decreased in number. Secondary few round spermatids were seen, but no elongated sperms observed. large basophilic inclusion-like body existed cytoplasm late pachytene spermatocytes. Genetic analysis revealed an autosomal...

Abstract A novel non-isotopic receptor binding technique for the detection of benzodiazepines is described. benzodiazepine labeled with europium chelate was prepared and employed as a ligand, time-resolved measurements long lifetime fluorescence allowed avoidance interference due to proteins in preparation. Experimental results demonstrate sigmoid inhibition curve, ligand inhibited by comparable concentrations unlabeled drug. The proposed assay may provide simple procedure measurement...

The first digital sensor used in intraoral radiography, RadioVisioGraphy was introduced 1987. It based on the activity of a charged-Coupled Device (CCD) sensor. Later on, other sensors became commercially available, including Digora featuring an imaging plate coated with photostimulable phosphor (PSP) 1994 and complementary metal-oxide semiconductorbased sensor, CDR active pixel 1998. These technologies have recently undergone considerable improvement, several dental clinics switched from...

YAG laser-assisted etching techniques were developed and investigated for realising silicon microstructures. Gases, including HCl, SF6 NF3 used etching. These produce volatile exhaust at atmospheric pressure. was applied to fabricate an electrostatic microactuator, resonating sensors accelerometers. This resistless dry can be three-dimensional
