BACKGROUND The apparent differences in risk factors for intra- and extracranial atherosclerosis are unclear and the mechanisms that underlie strokes in patients with intracranial atherosclerosis are not well known. We investigated the conventional vascular risk factors as well as other factors in stroke patients with large artery atherosclerosis. METHODS Using diffusion weighted imaging (DWI)...

Rapid occlusion of the middle cerebral artery (MCA) was undertaken in 5-6 week old rats to determine whether or not the young spontaneously hypertensive rat (SHR) or the normotensive Sprague-Dawley rat (SD) is protected against cerebral infarction by collateral circulation. Rats were killed 3 days after MCA occlusion and administration of Evans blue. As compared to SD, the SHR had elevated bloo...

A 78-year-old woman suffered sudden-onset left hemiparesis. There were no remarkable infectious findings. Computed tomography (CT) demonstrated a low-intensity area supplied by the right middle cerebral artery (MCA). The diagnosis was cerebral ischemia and she was conservatively treated with hyperosmotic fluids. Two days after the ischemic stroke she suddenly became comatose. CT showed diffuse ...

Background. Elevated middle cerebral artery peak systolic velocity (MCA-PSV) has been reported in nonanemic fetuses following fetal transfusion, and has been attributed to a major population of red blood cells (RBCs) with an adult mean corpuscular volume (MCV) in the fetal circulation. Reported here is an analogous case of elevated MCA-PSV with a normal fetal hematocrit and relative fetal micro...

OBJECTIVE This study describes the parenting and psychopathology of mothers with ADHD of adolescents with ADHD (MCA), non-ADHD mothers of adolescents with ADHD (CA), and non-ADHD mothers of adolescents without ADHD (COMP). METHOD Two sets of pairwise comparisons: (a) COMP versus CA and (b) CA versus MCA were conducted. We hypothesized that CA would experience greater distress in parenting and...

Motion cueing algorithms (MCA) are often applied in the motion simulators. In this paper, a nonlinear optimal MCA, taking into account translational and rotational motions of simulator within its physical limitation, is designed for platform aiming to minimize human’s perception error order provide high degree fidelity. Indeed, movement sensation center most MCA placed at upper platform, which ...

The basal level and hormone-affectedaminoacidtrans portof rat hepatocytesand rat hepatomacell lines H4-bI E-C3 (H35), HTC, McA-RH8994 (8994), and McA-RH7777 (7777) in culture were examined by investigating the amount of a-[1-14C]-aminoisobutyricacid (AIB) trans ported in 4 mm and up to 4 hr at 37°. The substances testedwere insulin,dexamethasone(DEX),glucagon,and dibutyryl cyclic adenosine 3' ...

In this paper, we investigate the complexity of computing locally optimal solutions for the local search problem MAXIMUM CONSTRAINT ASSIGNMENT (MCA). For our investigation, we use the framework of PLS, as defined in Johnson et al. [9]. In a nutshell, the MCA-problem is a local search version of weighted, generalized MAXSAT on constraints (functions mapping assignments to integers) over variable...

We investigated the effect of TTC-909, a drug preparation of the stable prostaglandin I(2) analogue clinprost (isocarbacyclin methylester; methyl 5-[(1S,5S,6R,7R)-7-hydroxy-6-[(E)-(S)-3-hydroxy-1-octenyl] bicyclo[3.3.0]oct-2-en-3-yl] pentanoate) incorporated into lipid microspheres, on cerebral infarction 7 days after permanent occlusion of the middle cerebral artery (MCA) in stroke prone spont...
