OBJECTIVE To evaluate the presence of ryudocan in follicular fluid (FF) and its possible correlation with FF E(2) and P, and to study the levels of ryudocan in granulosa-lutein cells stimulated with hCG. DESIGN Controlled clinical study and in vitro experiment. SETTING University teaching hospital. PATIENT(S) One hundred seven patients undergoing IVF.(More)
Background: The water splash patterns strongly depend on the surface conditions of the solid object. The present paper discusses the influence of the surface conditions of the solids falling into the water on the formation of the splashes, employing the experimental method with the high speed video camera and the numerical approach by the particle method.(More)
Cytoplasmic streaming (CPS) is well known to assist the movement of nutrients, organelles and genetic material by transporting all of the cytoplasmic contents of a cell. CPS is generated by motility organelles that are driven by motor proteins near a membrane surface, where the CPS has been found to have a flat velocity profile in the flow field according(More)
By means of real time B-scan, human fetal breathing movements (FBM) was basically and clinically investigated on 244 observations in 215 pregnancies. The results obtained were as follows. (1) FBM was frequently observed during active sleep in which FHR variability and fetal movement increased. (2) The incidence of FBM increased rapidly from 12.5% at 23-27(More)
We experimentally investigated the influence of a head shape of a solid body plunging into water on splash formation. Three different head shapes were tested: a hemisphere, cone, and circular cylinder. A hemisphere as a tail shape is common to all three head shapes. We captured images of splash formation using a high-speed CMOS camera. We found that a film(More)
We have experimentally observed the forms of splash caused by spheres diving into water, where the spheres are made of hydro-gel or acrylic resin[1]. The experimental results have shown that the splash by the hydro-gel sphere has formed the crown-type one, whereas the acrylic sphere formed the column-type one despite the same experimental condition.

Platelet aggregation inhibitor (PPAI) from the human placenta was partially purified and the effects of PPAI on the platelet aggregation were investigated. The results are as follows. 1) The final recovery of PPAI was 1.7% of the starting microsomal fraction. 2) The molecular weight of PPAI was estimated to be 240,000 by gel filtration on a Sephadex G-200(More)
