Automatic detection of wipes and their frame ranges is important for the purpose of reliable video parsing and video database indexing. Wipes are difficult to detect because of the complexity and variety of the transition effects. Many of the existing wipe detection algorithms could detect only a few wipe effects. The false/miss detection problem caused by(More)
Olfactory deficits and degenerative changes in central olfactory pathways are prominent in patients with Alzheimer's disease (AD). We hypothesized that peripheral olfactory neurons that reside in the nasal epithelium would show degenerative changes similar to the characteristic pathologic features of AD brain. Immunohistochemical studies of nasal tissue(More)
Identifying the small molecules that permit precise regulation of embryonic stem (ES) cell proliferation should further support our understanding of the underlying molecular mechanisms of self renewal. In the present study, we showed that PGE2 increased [3H]-thymidine incorporation in a time and dose dependent manner. In addition, PGE2 increased the(More)
Alpha1a-adrenergic receptor (AR) primarily mediates the contraction of the prostatic and cavernous smooth muscles. Among clinically available alpha1-AR antagonists for the medical management of benign prostatic hyperplasia (BPH), tamsulosin has a modest selectivity for alpha1A- and alpha1D- over alpha1B-ARs. To compare the effects of various alpha1-AR(More)
This study was intended to explore the effects of endothelium-independent, direct smooth muscle relaxants(papaverine, verapamil) and endothelium-dependent vasodilators(acetylcholine, bradykinin, adenosine) on the isolated cavernosal smooth muscle strips taken from diabetic men with impotence. When smooth muscle contraction was evoked with norepinephrine for(More)
We report three autopsy cases of congenital cytomegalovirus (CMV) infection in fetuses with a review of literature. The clinical manifestations in these cases of congenital CMV infection include intrauterine fetal death, hydrops fetalis, and CMV pneumonia associated with cardiovascular defect. The pathological characteristics were as follows: 1) the kidney(More)
Galectins have the potential to provide a promising alternative for unveiling the complexity of embryonic stem (ES) cell self-renewal, although the mechanism by which galectins maintain ES cell self-renewal has yet to be identified. Galectin-1 increased [3H]-thymidine incorporation as well as cyclin expression and decreased p27kip1 expression. Src and(More)
High salinity in soil is one of the major abiotic stresses leading to the reduction of rice yield. In this study, two salt-tolerant rice mutants induced by gamma-irradiation were selected for in vivo and vitro screening techniques, and their physiological characteristics were evaluated. Using a salt stress screening based on the Standard Evaluation System,(More)
In vitro and in vivo studies were performed to determine the potential use of tamsulosin (TAM) versus phentolamine (PHE) for intracavernosal injection (ICI) therapy when mixed with papaverine (PAP) and/or prostagladin E1 (PGE1) or with vasoactive intestinal polypeptide (VIP) for the treatment of erectile dysfunction. We performed isometric tension studies(More)
The effects of ultraviolet (UV) light (310 nm) on human cavernosal smooth muscles were investigated. Cavernosal strips were obtained from men during penile prosthetic surgery. When the cavernosal strips were irradiated with UV light in an organ bath, after precontraction by norepinephrine (100 nM) for 10, 20, 40 and 90 s at intervals of 3 min, the(More)
