STUDY OBJECTIVE To compare the operative outcomes of patients undergoing either single-port or multiport laparoscopic hysterectomy (LH). METHODS Two hundred fifty-six women scheduled for LH for symptomatic myoma and/or adenomyosis from 8 tertiary teaching hospitals were randomized to single-port or multiport groups. Primary outcome was conversion and/or(More)
OBJECTIVE To compare surgical outcomes of laparoendoscopic single-site myomectomy (LESS-M) vs. conventional laparoscopic myomectomy (LM). DESIGN Multicenter, noninferiority, randomized, controlled trial. SETTING University hospitals. PATIENT(S) A total of 100 subjects with symptomatic uterine myomas were randomly assigned to either LESS-M or(More)
Functional nanofibrous materials composed of gelatin-apatite-poly(lactide-co-caprolactone) (PLCL) were produced using an electrospinning process. A gelatin-apatite precipitate, which mimicked bone extracellular matrix, was homogenized in an organic solvent using various concentrations of PLCL. A fibrous structure with approximate diameters of a few hundred(More)
BACKGROUND This study explored the pharmacokinetics, tissue distribution, and excretion profile of zinc oxide (ZnO) nanoparticles with respect to their particle size in rats. METHODS Two ZnO nanoparticles of different size (20 nm and 70 nm) were orally administered to male and female rats, respectively. The area under the plasma concentration-time curve,(More)
This study questioned whether the mechanisms of resistance to antiestrogens differ when acquired under premenopausal (Pre-M) vs. postmenopausal (PM) conditions and whether structurally diverse antiestrogens induce adaptation of differing signaling pathways. To address this issue, we conducted systematic studies under Pre-M vs. PM culture conditions with(More)
In order to improve the solubility and bioavailability of a soy isoflavone extract (IFE), inclusion complexes (IFE-beta-CD) of the isoflavone extract with beta-cyclodextrin (beta-CD) were prepared and studied for their solubility and bioavailability. The aqueous solubility of the complexes of IFE with beta-CD (2.0 mg/ml) was about 26 times that of IFE(More)
Hormone-dependent breast cancers respond to inhibitors of estrogen synthesis or action with tumor regression and with a reduction of new metastases. The mechanisms underlying the effects of estrogen on metastasis likely differ from those on tumor regression. Cell migration is a key first step in the metastatic process. Based on our prior work and other(More)
Silver nanoparticles (AgNPs) have found a variety of uses including biomedical materials; however, studies of the cytotoxicity of AgNPs by size effects are only in the beginning stage. In this study, we examined the size-dependent cellular toxicity of AgNPs using three different characteristic sizes (∼ 10, 50, and 100 nm) against several cell lines(More)
Anthocyanins in a variety of plant species have been identified and are known for its hypolipidemic and anti-obesity effects. The effect of anthocyanins extracted from black soybean on body weight and daily food intake in adult rats raised on normal diet were studied. Male Sprague-Dawley rats were daily intra-gastric administered water or anthocyanins 6(More)
Inorganic bioactive nanomaterials are attractive for hard tissue regeneration, including nanocomponents for bone replacement composites and nanovehicles for delivering therapeutics. Bioactive glass nanoparticles (BGn) have recently gained potential usefulness as bone and tooth regeneratives. Here we demonstrate the capacity of the BGn with mesopores to load(More)
