Molecules are promising candidates for electronic device components because of their small size, chemical tunability, and ability to self-assemble. A major challenge when building molecule-based electronic devices is forming reliable molecular junctions and controlling the electrical current through the junctions. Here, we report a three-terminal junction(More)
Progesterone, an important factor in the maintenance of gestation in humans and animals, has been demonstrated to lower immune response during pregnancy [Siiteri PK, Stites DP, Immunologic and endocrine interrelationships in pregnancy, Biol Reprod, (1982); Watnick AS, Russo RA, Survival of skin homografts in uteri of pregnant and progesterone-estrogen(More)
The great shortage of human hepatic cells makes it desirable to generate extrahepatic stem or precursor cells. In recent years, it has been reported that human multipotential mesenchymal stem cells (hMSCs) differentiate into hepatocyte-like cells. The fetal lung is one of the largest organs containing many MSCs that can be easily obtained. Whether MSCs from(More)
Midkine (MK), a heparin-binding growth factor, is expressed highly in various malignant tumors, so it acts as attractive therapeutic target. In the present study, we used siRNA targeting MK to downregulate human MK expression in human gastric cancer cell line BGC823 and SGC7901 so as to determine the advantages of this anticancer therapeutic. The cell(More)
Human Zbtb7A was proved to be an important molecular switch in oncogenesis. However, it is difficult to obtain its protein expression in prokaryotic system, due to high G+C content and rare codons in zbtb7a gene. Therefore, to further research the function and application of this protein, we optimized its coding sequence according to the codon bias of(More)
A fluoroglycofen ethyl-degrading bacterium, MBWY-1, was isolated from the soil of an herbicide factory. This isolated strain was identified as Mycobacterium phocaicum based on analysis of its 16S rRNA gene sequence and its morphological, physiological, and biochemical properties. The strain was able to utilize fluoroglycofen ethyl as its sole source of(More)
The electrical, optical and other important properties of colloidal nanocrystals are determined mainly by the crystals' chemical composition, size and shape. The introduction of specific dopants is a general approach of modifying the properties of such nanocrystals in well-controlled ways. Here we show that in addition to altering the atomic composition of(More)
This study aimed to isolate promising halotolerant and alkalotolerant plant growth-promoting rhizobacteria and to study their effects on the growth of tall fescue and phytodegradation efficiency in a petroleum-contaminated saline-alkaline soil. A total of 115 PGPR strains were isolated from the rhizosphere of tall fescue grown in petroleum-contaminated(More)
Midkine (MK), a heparin-binding growth factor, can regulate cell growth, survival and differentiation. MK is expressed at high levels in a variety of human carcinomas. Recently, the urine and serum MK concentration was analyzed in gastric cancer patient. However, the association of the cytokine mRNA expression with the categorical clinicopathological(More)
A novel platform based on a hairpin oligonucleotide (HO) switch, gold nanoparticles (AuNPs), and enzyme signal amplification for the ultrasensitive detection of mucin 1 protein (MUC1) was developed in this assay. This HO aptamers and horseradish peroxidase (HRP) were immobilised on the AuNPs to yield HO-AuNP-HRP conjugates. AuNPs were used as labels and(More)
