Umbrella-Shaped Amphiphiles: Internal Alkylation of an Aromatic Micelle and Its Impact on Cavity Features.

To develop new hybrid micelles with alkyl/polyaromatic core-shell structures, we synthesized umbrella-shaped amphiphiles bearing a bent anthracene dimer with a linear alkyl chain (i.e., octyl and hexadecyl groups).

Scraping of foam on a substrate.

Hypothesis: Foam is not only an industrially important form of matter, but also one of soft jammed system such as colloidal suspensions and emulsion suspensions. Since foams are composed of gas bubbles and liquid, it is expected that the coupling of bubbles and liquid strongly affects rheology of foams, which is different from simple liquids. To reveal this coupling effect and considering the importance of foam applications, we studied the scraping of foam by a rigid plate on a substrate.

Prospective study of intramuscular ergometrine compared with intramuscular oxytocin for prevention of postpartum hemorrhage.

Aim: To compare the efficacy and safety of intramuscular oxytocin with intramuscular ergometrine in the management of postpartum hemorrhage during the third stage of labor.

Methods: Women who had been pregnant for more than 35 weeks and delivered cephalic singletons vaginally without predelivery administration of oxytocics were included. The cases considered to be at high risk were excluded, such as those who had uterine fibroids, a previous cesarean section, previous postpartum hemorrhage, or severe anemia.

Hypoadiponectinemia in lean lactating women: Prolactin inhibits adiponectin secretion from human adipocytes.

Adiponectin is an adipocyte-derived hormone involved in glucose, lipid and energy metabolism. A low plasma adiponectin concentration is associated with insulin resistance, obesity and atherosclerosis. In women, energy homeostasis is remarkably changed during gestation and lactation in order to supply sufficient nutrition for a fetus or newborn.

Statistics on deliveries of mothers with epilepsy at Yokohama City University Hospital.

Purpose: To survey and summarize the treatment of pregnant women with epilepsy and to obtain data for the improvement of daily treatment regimens.

Methods: We reviewed medical records of 36 deliveries of 25 mothers with epilepsy at Yokohama City University Hospital from September 1991 to December 2000 and statistically compared the differences in drug-taking profiles, complications during pregnancy, types of delivery, and complications at delivery between the epilepsy group and a control group (656 total deliveries after 22 weeks except for epilepsy cases in 1991 and 1992 at Yokohama City University Hospital).

Results: Of the 25 mothers with epilepsy, three with idiopathic generalized epilepsy, 12 were symptomatic for partial epilepsy.

Hemimegalencephaly misdiagnosed as a congenital brain tumor by fetal cerebral ultrasonography.

Objective: To describe a case of hemimegalencephaly misdiagnosed prenatally.

Case Report: We presented a neonate with hemimegalencephaly, who was thought to have a congenital brain tumor by fetal cerebral ultrasonography. Postnatal MRI findings showed hemimegalencephaly characterized by mild enlargement of the affected hemisphere with a predominantly abnormal signal in the frontal lobe.
