“Smart” polymer gels actively change their size, structure, or viscoelastic properties in response
to external signals. The stimuli-responsive properties, indicating a kind of intelligence, …

Introduction This systematic review aims to elucidate the diagnostic accuracy of radiological
examinations to distinguish between brain radiation necrosis (BRN) and tumor progression (…

Deformation of acrylic acid–acrylamide copolymer gels in an aqueous solution under the
influence of a dc electric field was studied. In the electric field, the gel swells, shrinks, or bends. …

Dynamic viscoelasticity of silicone gels having many lines of dispersed iron particles under
the influence of external magnetic fields was studied. The particulate composite enhanced its …

BACKGROUND: A decreased concentration of beta amyloid (1-42) (Aβ42) has consistently
been found in the cerebrospinal fluid (CSF) of patients with Alzheimer's disease (AD) and is …

A new gas-utilizing battery using mixed gas of O2 and CO2 was developed and proved its
very high discharge capacity. The capacity reached three times as much as that of a non-…

Purpose : Accurate diagnosis of tumor extent is important in three-dimensional conformal
radiotherapy. This study reports the use of image fusion between (18)F-fluoro-2-deoxy-D-…

BACKGROUND AND PURPOSE: Blood vessels are usually conspicuous on dynamic CT
perfusion images. The presence of large vessels may lead to overestimation of the quantitative …

Bending of poly(vinyl alcohol) hydrogel mixed with poly(sodium acrylate) chains, PVA–PAA
gel, under the influence of dc electric fields was studied. The PVA–PAA gel was prepared by …

Glioma is the most common malignant brain tumor. Hypoxia is closely related to the malignancy
of gliomas, and positron emission tomography (PET) can noninvasively visualize the …
