Mesoporous silica capsules with submicrometer sizes were successfully prepared via the interfacial hydrolysis and condensation reactions of tetraethoxysilane (TEOS) in inverse miniemulsion by using hydrophilic liquid droplets as template. The inverse miniemulsions containing pH-controlled hydrophilic droplets were first prepared via sonication by using(More)
Of 122 consecutive procedures, 31 were not assisted hatching (AH), which served as the control group, 34 were AH with 40 microm thinning of the zona, and 57 were AH with 80 microns of the zona thinning. The pregnancy and implantation rates were significantly higher in 80 microns thinning group compared to control group (40.3 vs. 16.1 percent, P=0.03; 21.5(More)
BACKGROUND The objective of this study was to measure the antibody content of NuTu-19 ovarian cancer cells in serum samples using a quartz crystal microbalance (QCM) immunosensor. MATERIALS AND METHODS NuTu-19 cells were first cultured onto the electrode surfaces of crystals in Dulbecco's modified Eagle medium, and then specified amounts of immunized(More)
OBJECTIVE Our study aimed to assess the distribution of blood lead level and its relationship to essential elements in preschool children in an urban area of China. DESIGN AND METHODS A total of 6741 children aged 0- to 6-year-old were recruited. Levels of lead, zinc, copper, iron, calcium, and magnesium in whole blood samples were determined using atomic(More)
OBJECTIVE Explore the model of universal NICU newborns' hearing screening in high-risk neonates, preliminary understanding factor of hearing damage. METHOD Transient evoked otoacoustic emissions (TEOAE) and automatic auditory brainstem response (AABR) were used to detect newborns' hearing in 13 315 objects, that is newborns' hearing screening in NICU with(More)
BACKGROUND The selection of pre-embryos for transferred is based on morphological appearance. But some poor quality cleaved embryos also can be cultured to the blastocyst stage and implanted. OBJECTIVE To assess the clinical pregnancy outcomes of blastocyst transfer which developed from poor quality embryos. MATERIALS AND METHODS A total of 109 cleaved(More)
BACKGROUND The effect of heparin in improving cancer survival has gained increasing attention over the past decades. Several clinical trials have evaluated the role of heparin on survival outcome and its safety profile in lung cancer patients. Thus, we performed a systematic review and meta-analysis from the results of randomized controlled trials (RCTs) to(More)
OBJECTIVES The aim of this study was to investigate blood lead level and its relationship to essential elements (zinc, copper, iron, calcium and magnesium) in school-age children from Nanning, China. METHODS A total of 2457 children aged from 6 to 14 years were enrolled in Nanning, China. The levels of lead (Pb), zinc (Zn), copper (Cu), iron (Fe), calcium(More)
The objective of this study was to evaluate the gestational results obtained with vitrified-thawed human cleavage-stage embryo by two different thaw protocols. Embryo development was observed to cleavage-stage and embryos were cryopreserved by vitrification on day 3 after oocyte retrieval. 51 cycles were thawed using vitrification warming kit with(More)
