Blastocystis has a widespread distribution in a variety of animals, which is a potential source of infection for humans. Previous studies show that Blastocystis sp. subtypes 1-4, 6, and 7 were composed of isolates from humans and animals, while Blastocystis sp. subtype 5 included only pig and cattle isolates. A more recent study on the basis of the SSU rDNA(More)
In the present study, a DNA sequence encoding a small heat shock protein gene (FcHsp21) in the Chinese shrimp, Fenneropenaeus chinensis, was cloned, and its expression was analyzed after white spot syndrome virus (WSSV) infection. The FcHsp21 gene contained an open reading frame (ORF) of 555 bp in length, encoding a 184 amino acid protein with a theoretical(More)
The β-1,3-D: -glucan binding protein (βGBP), one kind of the pattern recognition proteins (PRPs), was cloned and characterized from the Chinese Shrimp Fenneropenaeus chinensis, and named as FcβGBP-HDL. The results indicated that the full length cDNA of 6713 bp had an open reading frame encoded a polypeptide of 2139 amino acids with two glucanase-like motifs(More)
The possibility of superconductivity in tetragonal FeS has attracted considerable interest because of its similarities to the FeSe superconductor. However, all efforts made to pursue superconductivity in tetragonal FeS have failed so far, and it remains controversial whether tetragonal FeS is metallic or semiconducting. Here we report the observation of(More)
The ubiquitous coexistence of majority insulating 245 phases and minority superconducting (SC) phases in A(x)Fe(2-y)Se(2) (A = K, Cs, Rb, Tl/Rb, Tl/K) formed by high-temperature routes makes pure SC phases highly desirable for studying the intrinsic properties of this SC family. Here we report that there are at least two pure SC phases,(More)
Controlling and monitoring the drug delivery process is critical to its intended therapeutic function. Many nanocarrier systems for drug delivery have been successfully developed. However, biocompatibility, stability, and simultaneously tracing drugs and nanocarriers present significant limitations. Herein, we have fabricated a multifunctional nanocomposite(More)
Metal-intercalated iron selenides are a class of superconductors that have received much attention but are less understood in comparison with their FeAs-based counterparts. Here, the controversial issues such as Fe vacancy, the real phase responsible for superconductivity, and lattice stability have been addressed based on first-principles calculations. New(More)
The mixed-metal sulfide compound with the formula Ba2Fe0.6V1.4S6 was successfully synthesized via solid-state reaction. Ba2Fe0.6V1.4S6 has a quasi-one-dimensional structure and crystallizes in the hexagonal space group P63/mmc. The structure is composed of face-sharing anion octahedron [MS6]8- (M = V or Fe) units to construct infinite chains along the c(More)
Two chromium chalcogenide Cs[Cr(en)2GeSe4] () and Cs[Cr(en)2SnSe4] () have been synthesized by a solvothermal method. Both compounds crystallize in the monoclinic space group P21/n. The structures of the two compounds are characterized by isolated [Cr(en)2MSe4](-) clusters separated by Cs(+) ions. The optical properties of the two compounds were measured(More)
A C-type lectin-like protein was cloned and characterized from the Chinese shrimp Fenneropenaeus chinensis, and named as FcCTL. The results indicated that the full length cDNA of 859 bp had an open reading frame encoded a polypeptide of 220 amino acids with one carbohydrate-recognition domain, six conserved Cys and one key motif EPGD. The theoretical(More)
