The incidence of gestational diabetes mellitus (GDM) has increased dramatically amongst multiethnic population. However, how gestational diabetes mellitus damages the developing embryo is still unknown. In this study, we used yolk sac membrane (YSM) model to investigate angiogenesis in the developing chick embryo. We determined that in the presence of high(More)
Dural arteriovenous fistulas (DAVFs) are associated with venous hypertension. Numerous studies have revealed high expression levels of vascular endothelial growth factor (VEGF) in human DAVF specimens, as well as in animal models of experimental venous hypertension. The objective of the present study was to clarify whether the VEGF signaling pathway is(More)
Dexamethasone (Dex) has anti-inflammatory and immunomodulatory properties against many conditions. There is a potential teratogenic risk, however, for pregnant women receiving Dex treatment. It has been claimed that Dex exposure during pregnancy could affect osteogenesis in the developing embryo, which still remains highly controversial. In this study, we(More)
Gestational diabetes is defined as glucose intolerance during pregnancy and it is presented as high blood glucose levels during the onset pregnancy. This condition has an adverse impact on fetal development but the mechanism involved is still not fully understood. In this study, we investigated the effects of high glucose on the developing quail embryo,(More)
Worldwide, n-hexane is an organic solvent widely used in numerous industries such as chemical engineering, pharmaceutical and cosmetic industry. 2,5-Hexanedione (2,5-HD) is the main metabolite of n-hexane. It is now gradually recognized that chronic exposure to n-hexane could harm the health of people. Nevertheless, it is still unclear whether or not 2,5-HD(More)
d-Cycloserine (DCS), a partial agonist at the strychnine-insensitive glycine recognition site on the N-methyl-d-aspartate (NMDA) receptor complex, has been shown to facilitate the extinction and prevent the relapse of cocaine-induced conditioned place preference (CPP) when administered before or after each extinction trail. However, some studies have(More)
BACKGROUND The developing embryo is very sensitive to oxidative stress and excess reactive oxygen species (ROS) generation is often associated with cardiovascular malformation. However, little is known about the adverse effects of ROS during heart morphogenesis, especially during the formation of the atria and ventricles. METHODS AND RESULTS We have(More)
We performed this study to report our experience using a stepwise stent deployment technique for the treatment of tandem intracranial aneurysms. Patients with intracranial tandem aneurysms that were treated with a stepwise stent deployment technique between May 2009 and June 2013 were retrospectively reviewed. Twenty-one patients with 42 tandem aneurysms(More)
