The structures of two novel 3,4-seco-lanostane-type triterpenes isolated from the sclerotium
of Poria cocos were established to be 16α-hydroxy-3,4-seco-lanosta-4(28),8,24-triene-3,21-…

Introduction Hemodynamics is thought to play a very important role in the initiation, growth,
and rupture of intracranial aneurysms. The purpose of our study was to compare …

and rupture of intracranial aneurysms. The purpose of our study was to perform in vivo …

Purpose To visualize the hemodynamics of the intracranial arteries using time‐resolved
three‐dimensional phase‐contrast (PC)‐MRI (4D‐Flow). Materials and Methods MR …

The regioselective silylation of C(sp 3 )–H bonds at the benzylic position in 4-alkylpyridines
with hydrosilanes is described. The reaction proceeds in the presence of a catalytic amount …

The iridium-catalyzed C(sp 3 )–H silylation of 2-alkylpyridines with hydrosilanes at the
benzylic position to afford 2-(1-silylalkyl)pyridines is described. The low product yield was …

Since Hewish et al. (1964) discovered the interplanetary scintillation (IPS) phenomena, the
IPS method has been used as one of the few devices which can be used to observe solar …

A new interpretation is proposed for stimulus‐induced signal changes in diffusion‐weighted
functional MRI. T 2 ‐weighted spin‐echo echo‐planar images were acquired at different …

OBJECTIVE. The purpose of our study was to evaluate the clinical feasibility and usefulness
of a 2D spoiled gradient-recalled echo MR sequence with serial switching of reversed …

Susceptibility and neutron scattering measurements were performed for Pd 1− x Cr x (x=
0.075, 0.11, 0.15) alloy single crystals. In neutron scattering measurements, satellite diffuse …
