Although fluorescence imaging diagnosis of the differences between cancer cells and normal cells by targeting ligand-based fluorescent probes is useful for recommending personalized therapy to patients, using the differences to diagnose a wide range of cancers is often not possible due to the genetic or phenotypic heterogeneity of cancer cells. In this work a 2-(diphenylphosphino)phenol-functionalized pyronin POP was presented as a dual-channel fluorescence agent for diagnosing a wide range of cancer cell types...

OBJECTIVE: Serum human epididymis protein 4 (HE4) and transthyretin (TTR) are new markers for ovarian cancer. We compared HE4 and TTR with the gold marker CA-125 for the diagnosis of ovarian cancer patients. METHODS: 130 serum samples from benign ovarian tumor and 400 serum samples from healthy women were used to set up the cut-off. 126 serum samples from ovarian cancer patients before operation were collected to test the diagnostic value of these ELISA assays. The sensitivity, positive predictive value (PPV) and ROC curves were used to evaluate the diagnostic value...

Ban-Lan-Gen, the root tissues derived from several morphologically indistinguishable plant species, have been used widely in traditional Chinese medicines for numerous years. The identification of reliable markers to distinguish various source plant species is critical for the effective and safe use of products containing Ban-Lan-Gen. Here, we analyzed and characterized the complete chloroplast (cp) genome sequence of Strobilanthes cusia (Nees) Kuntze to identify high-resolution markers for the species determination of Southern Ban-Lan-Gen...

How to improve the accuracy of target detection substance in low-content and complex of real sample, which is still a major challenge in the analysis field. There is no doubt that the internal standard method is the best choice in the analysis methods. The internal standard method of ECL strategy can furnish more accurate detection results in the changeable complex environment, and it can dispel the primary vaguest interference in the system through the self-calibration of two emission spectra. Herein, we effectually explored a strong and stable bimodal ECL system based on graphitic carbon nitride quantum dots (g-CNQDs) as single luminophore in the presence of double coreactants potassium persulfate (K2 S2 O8 ) and tetrabutylammonium bromide (TBAB) under the optimized conditions...

Although multiple roles of lipases have been reported in yeasts and microalgae, the functions of lipases have not been studied in oleaginous filamentous fungi. Lipase Lip6 has been reported in the oleaginous filamentous fungus Mucor circinelloides with the consensus lipase motif GXSXG and the typical acyltransferase motif of H-(X)4 -D. To demonstrate that Lip6 might play dual roles as a lipase and an acyltransferase, we performed site-directed mutagenesis in the lipase motif and the acyltransferase motif of Lip6...

BACKGROUND: 40-50% of colorectal cancer (CRC) patients develop metastatic disease; the presence of metastasis hinders the effective treatment of cancer through surgery, chemotherapy and radiotherapy, which makes 5-year survival rate extremely low; therefore, studying CRC metastasis is crucial for disease therapy. In the present study, we investigated the role of rhomboid domain containing 1 (RHBDD1) in tumor metastasis of CRC. METHODS: The expression of RHBDD1 was analyzed in 539 colorectal tumor tissues for its correlation with lymphatic metastasis and distal metastasis...

BACKGROUND Ras-related C3 botulinum toxin substrate 1 (Rac1) is implicated in a variety of cellular functions and is related to tumor growth and metastasis. This study aimed to explore the role of Rac1 in hypopharyngeal squamous cell carcinoma (HSCC). MATERIAL AND METHODS The Rac1 expression in HSCC tissues was determined by quantitative real-time polymerase chain reaction and Western blot analysis. The level of Rac1 in HSCC cells was downregulated by a Rac1-specific shRNA. Then, the growth and metastasis of HSCC cells were assessed in vitro by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay, flow cytometry, Hoechst staining, and Transwell assay...

Objective: To explore whether Rhaponticum uniflorum ( R. uniflorum ) had anti-tumor effects in oral cancer and investigate the molecular mechanisms involved in these anti-tumor effects. Methods: Chemical compositions of R. uniflorum ethyl acetate (RUEA) extracts were detected by ultra-performance liquid chromatography-Q/time-of-flight mass spectrometry (UPLC-Q/TOF-MS), followed by pharmacology-based network prediction analysis. The effects of RUEA extracts on proliferation, apoptosis, migration, and invasion ability of human oral squamous cell carcinoma (OSCC) cell line SCC15 were evaluated by CCK8 assay, Annexin V- fluorescein isothiocyanate/propidium iodide staining, wound healing assay, and Matrigel invasion assay, respectively...

Magnetic NiAl layered doubled hydroxide (LDH)/Fe3 O4 -RGO composites were successfully synthesized via a simple hydrothermal route. The as-prepared samples were well characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). The results showed that NiAl LDH nanoplatelets and Fe3 O4 nanoparticles sized around 15 nm were uniformly anchored on the surface of graphene sheets. The NiAl LDH/Fe3 O4 -RGO25 photocatalyst was employed to degrade ciprofloxacin (CIP) in an aqueous solution under visible light irradiation...

A plasmonic nanostructure (PNS) which integrates metallic and dielectric media within a single structure has been shown to exhibit specific plasmonic properties which are considered useful in refractive index (RI) sensor applications. In this paper, the simultaneous realization of sensitivity and tunability of the optical properties of PNSs consisting of alternative Ag and dielectric of nanosphere/nanorod array have been proposed and compared by using three-dimensional finite element method. The proposed system can support plasmonic hybrid modes and the localized surface plasmonic resonances and cavity plasmonic resonances within the individual PNS can be excited by the incident light...

The influenza virus is a serious threat to public health worldwide. A novel avian influenza A (H7N9) virus with a mortality rate of approximately 30% has been identified as an unusually dangerous virus for humans by the World Health Organization. Pathogenic H7N9 continue to represent a public health concern, and several candidate vaccines are currently in development. We generated candidate H7N9 vaccine strains using reverse genetics, consisting of hemagglutinin and neuraminidase genes derived from a human H7N9 virus and the remaining genes from the PR8 (A/PuertoRico/8/34 (H1N1)) virus...

This study aimed to identify a new biological activity of the widely distributed species Fagopyrum dibotrys. Four F. dibotrys extracts (ethyl acetate (EA), petroleum ether (P), ethanol (E), and water (W)) were explored for their anti-neuraminidase (NA) activity. A total of 32 compounds were identified using UHPLC-Q-Exactive Orbitrap HRMS in the EA extract, which had the best NA inhibitory effects. We used the docking data for supporting compounds' anti-neuraminidase activity. Among them, five compounds including one flavonoid, three organic acids, and one glucoside were discovered for the first time in F...

Introducing frogs into paddy fields can control pests and diseases, and organic farming can improve soil fertility and rice growth. The aim of this 2-year field study was compare the yield and elemental composition of rice between an organic farming system including frogs (ORF) and a conventional rice culture system (CR). The grain yields were almost the same in the ORF system and the CR system. The ORF significantly increased the contents of phosphorus (P), ion (Fe), zinc (Zn), molybdenum (Mo) and selenium (Se) in rice grain at one or both years...
