The prevalence of helminths in the Asian water buffaloes (Bubalus bubalis) was investigated in Hunan Province, People's Republic of China between April 2005 and October 2007. A total of 359 adult buffaloes slaughtered at local abattoirs in 12 representative geographical locations in Hunan Province were examined for the presence of helminths. The worms were(More)
The medical community has expressed significant interest in the development of new types of artificial bones that mimic natural bones. In this study, computed tomography (CT)-guided fused deposition modeling (FDM) was employed to fabricate polycaprolactone (PCL)/hydroxyapatite (HA) and PCL 3D artificial bones to mimic natural goat femurs. The in vitro(More)
The host response to calcium silicate ceramic coatings is not always favorable because of their high dissolution rates, leading to high pH within the surrounding physiological environment. Recently, a zinc-incorporated calcium silicate-based ceramic Ca2ZnSi2O7 coating, developed on a Ti-6Al-4V substrate using plasma-spray technology, was found to exhibit(More)
There remains a great challenge in the sensitive detection of microRNA because of the short length and low abundance of microRNAs in cells. Here, we have demonstrated an ultrasensitive detection platform for microRNA by combining the tetrahedral DNA nanostructure probes and hybridization chain reaction (HCR) amplification. The detection limits for DNA and(More)
Ag@TiO2 core-shell-type nanophotocatalysts have been prepared using a simple and convenient method. The products were characterized by TEM, XRD, and UV-vis spectra. To make the catalysts achieve the highest photocatalytic activity under UV light illumination, the Ag content of Ag@TiO2 was optimized. The results showed that Ag@TiO2-doped Fe3+ extend their(More)
Sequence variability in three mitochondrial DNA (mtDNA) regions, namely cytochrome c oxidase subunit 3 (cox3), NADH dehydrogenase subunits 1 and 4 (nad1 and nad4) in Spirometra erinaceieuropaei spargana from different geographical regions in China was examined. A portion of each of the cox3 (pcox3), nad1 (pnad1) and nad4 genes (pnad4) were amplified(More)
Graphene oxide (GO) is an increasingly important nanomaterial, which exhibits great promise in the area of bionanotechnology and nanobiomedicine. In this study, we synthesized uniform ultrasmall graphene oxide nanosheets with high yield by a convenient way of modified Hummers' method. The uniform ultrasmall GO nanosheets, which exhibit fluorescence property(More)
The targeted therapeutic effect of nano drug delivery system for glioblastoma has been hampered by the weak enhanced permeability and retention (EPR) effect of glioblastoma and the low delivering efficiency of NDDS in glioblastoma tissue. In this study, a tumor-penetrating peptide (RGERPPR), the specific ligand of neuropilin-1 overexpressed on glioblastoma(More)
Fe3+-doped TiO2 (Fe-TiO2) porous microspheres were prepared by controlled hydrolysis of Ti(OC4H9)4 with water generated "in situ" via an esterification reaction between acetic acid and ethanol, followed by hydrothermal treatment. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic absorption flame(More)
Silk fibroin (SF) is a promising candidate for a variety of application in the fields of tissue engineering, drug delivery, and biomedical optics. Recent research has already begun to explore the construction of nano- and micropatterned SF films under ambient environment. The structure and biocompatibility of SF are dependent on SF state (solution or solid)(More)
