The temporal and spatial distribution of heavy metals (Cd, Hg, Pb, As and Cr) in Poyang Lake, the largest freshwater lake (3050 km(2)) in China, were studied based on the sedimentary profiles. For this purpose, eight sedimentary cores were selected which located at lake area, outfall of lake and the main branch rivers, respectively. High-resolution profiles(More)
Here, we report a widely applicable procedure for direct shoot regeneration via basal leaf segments of Lilium. Leaf segments (0.8–1.0 cm long and 0.4 cm wide) were excised from leaves on shoot nodes 3 to 6 of 4-wk-old in vitro stock shoot cultures. The segments were wounded by three transverse cuts across the midvein on the abaxial side, with 1 mm between(More)
High-density genetic linkage map plays an important role in genome assembly and quantitative trait loci (QTL) fine mapping. Since the coming of next-generation sequencing, makes the structure of high-density linkage maps much more convenient and practical, which simplifies SNP discovery and high-throughput genotyping. In this research, a high-density(More)
We developed a new electrochemiluminescence (ECL) platform for ultrasensitive and selective detection of leukemia cells. In order to construct the platform, the nonporous gold with controllable three-dimensional porosity and good conductivity was used to modify the screen-printed carbon electrode. The carbon quantum dots (CQDs) coated ZnO nanosphere(More)
S100B is a biomarker of nervous system injury, but it is unknown if it is also involved in vascular injury. In the present study, we investigated S100B function in vascular remodeling following injury. Balloon injury in rat carotid artery progressively induced neointima formation while increasing S100B expression in both neointimal vascular smooth muscle(More)
OBJECTIVE To explore the effects of rhEPO on the migration of bone marrow(BM) derived mesenchymal stem cells(MSCs) and its probable signal transduction mechanism. METHODS MSC was cultured by classical whole BM adherence method; MSC characteristics was identified by multi-differentiation and surface marker (CD90, CD133, CD34, CD105). The effect of(More)
Trichomes on plants, similar to fine hairs on animal and human bodies, play important roles in plant survival and development. They also represent a useful model for the study of cell differentiation. Although the regulatory gene network of unicellular trichome development in Arabidopsis thaliana has been well studied, the genes that regulate multicellular(More)
carbide-derived carbon, [ 12 ] carbon nanotubes (CNTs), [ 14–17 ] and graphene, [ 6 , 7 , 10 , 18 , 19 ] possess notable features including high surface area, high electrical conductivity, and good chemical stability, and therefore they have been widely explored as thinfi lm electrode materials for ASSSs. However, the fabrication of ASSSs generally involves(More)
Graphene, an individual two-dimensional, atomically thick sheet of graphite composed of a hexagonal network of sp(2) carbon atoms, has been intensively investigated since its first isolation in 2004, which was based on repeated peeling of highly oriented pyrolyzed graphite (HOPG). The extraordinary electronic, thermal, and mechanical properties of graphene(More)
Covalent organic frameworks are a class of crystalline organic porous materials that can utilize π-π-stacking interactions as a driving force for the crystallization of polygonal sheets to form layered frameworks and ordered pores. However, typical examples are chemically unstable and lack intrasheet π-conjugation, thereby significantly limiting their(More)
