Congenital heart disease (CHD) is the most frequently occurring congenital disorder in newborns and is the most frequent cause of infant death from birth defects. Human genetic studies have identified that numerous genes encoding transcription factors that regulate specific events in heart development are responsible for inherited and sporadic CHD. Nuclear(More)
In the present study, the extraction, purification, characterization and biological activities of polysaccharides from the seeds of Amomum villosum (ASP) were investigated. Firstly, the optimal parameters for the extraction of ASP were obtained by using a Box-Behnken Design as follows: extraction temperature 78.8 °C, extraction time 71.3 min and ratio of(More)
In the present study, the separation and purification characteristics of resveratrol from extract of peanut sprouts (PSE) on 11 macroporous adsorption resins were investigated. The results showed that ADS-5 offered better adsorption and desorption capacity for resveratrol than other tested resins. From the static experiments with ADS-5 resin, we found that(More)
In the present study, effect of different extraction methods on property and bioactivity of water-soluble polysaccharides (WSP) from the seeds of Amomum villosum were investigated. Firstly, four different extraction methods were used to extract WSP, which include hot water extraction (HWE), ultrasonic-assisted extraction (UAE), microwave-assisted extraction(More)
BACKGROUND IL-27, a member of the IL-12 family, has been involved in maternal tolerance to the foetus and successful pregnancy. Growing evidences indicate that IL-27 plays a crucial role in pregnancy. Aim We carried out the present study in order to investigate whether polymorphisms in the IL27 are associated with the risk for CHDs, including atrial septal(More)
In this paper, an economical and efficient technology for the extraction of resveratrol from peanut sprouts by multi-stage countercurrent extraction (MSCE) was investigated based on the alkaline extraction and acid precipitation method (AEAP). Firstly, the MSCE equipment and operation procedures were designed. Then, the optimal parameters of MSCE were(More)
The aim of the present study was to investigate the association between two single nucleotide polymorphisms (SNPs) and infertility in Chinese males using multi-analyte suspension array (MASA). A total of 196 male patients with azoospermia or severe oligospermia (sperm density <5x106/ml, non‑obstructed) who had a normal karyotype and no azoospermia factor(More)
BACKGROUND Cryptorchidism is one of the most common congenital anomalies in newborn boys. Although the mechanism responsible for the pathophysiology of cryptorchidism has not yet been well addressed, the Wnt signaling pathway has been involved in the development of cryptorchidism. Axin1 is a central component of the Wnt signaling pathway and may play a(More)
BACKGROUND The aim was to develop a better experimental model which could facilitate further studies assessing the vertical HCV gene transmission via human spermatozoa, and verify the possibility of father-to-child transmission of the HCV gene. METHODS The recombinant plasmid pIRES2-EGFP-HCV C was constructed. Fluorescence in situ hybridization was(More)
Due to the inconsistent effects of human immunodeficiency virus (HIV) on the human male reproduction in previous studies and the impacts of environmental exposures, such as heavy metals, on male reproduction receiving little attention in HIV-infected population, the aim of present study was to investigate whether heavy metals have potential effects on(More)
