    Notes: Fibrinogen and albumin are two of the most important plasma proteins that relate toblood coagulation caused by engineered surfaces. In this paper, the adsorption behavior of albuminand fibrinogen on single-walled carbon nanotubes nonwoven (SWNT nonwoven) was investigatedthrough scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), near edgeX-ray adsorption fine structure spectroscopy (NEXAFS) and direct enzyme-linked immunosorbentassay (ELISA) respectively. It was concluded that SWNT nonwoven displayed strong adsorptionpreference of fibrinogen to albumin. In addition, the immune activity of fibrinogen adhered to theSWNT nonwoven surface was found remained and showed a linear response to the concentration ina certain range

    q-Ideals and a-Ideals in BCI-Algebras (2000)
    Springer

    Notes: Abstract In this note we define the notions of q-ideals and a-ideals in BCI-algebras. We give several characterizations and the extensive theorems about q-ideals and a-ideals. We show that a non-empty subset of a BCI-algebra is a-ideal if and only if it is both q-ideal and p-ideal. Finally, we give four characterizations of associative BCI-algebras by a-ideals and eight characterizations of quasi-associative BCI-algebras by q-ideals.

    Electro-acupuncture decreases 5-HT, CGRP and increases NPY in the brain-gut axis in two rat models of Diarrhea-predominant irritable bowel syndrome( D -IBS) (2015)
    BioMed Central
    Details
    Publication Date: 2015-09-30
    Description: Background: To examine whether electro-acupuncture (EA) could decrease 5-hydroxytryptamine (5-HT) and calcitonin gene-related peptide (CGRP), and increase neuro-peptide Y (NPY) in the brain-gut axis (BGA) in D-IBS using rat models. Methods: Rats were randomly exposed to unpredictable chronic stress for 3 weeks followed by 1-hour acute restraint stress (CAS) after 7 days of rest, or daily gavage of Senna decoction (6 g/kg) plus chronic restraint stress (for a duration of 2 h, starting from 1 h prior to the gavage) for 2 weeks (ISC). The content of 5-HT, CGRP and NPY in the distal colon, spinal cord, hypothalamus was examined at the end of the treatment. Results: 1. The two rat models exhibited similar characteristics, e.g., increased number of fecal pellets expelled in 1 h, decreased sacchar-intake, decreased CRD, elevated 5-HT, CGRP content and decreased NPY in the distal colon, spinal cord, hypothalamus (P

    Counterion-Directed Assembly of Praseodymium(III) Compounds based on the Flexible Ligand 5-Aminotetrazole-1-propionic Acid (Hatzp) (2015)
    Wiley-Blackwell
    Details
    Publication Date: 2015-12-10
    Description: Different kinds of counterions (such as NO 3 – , ClO 4 – , and Cl – ) play a special role in controlling the framework of coordination compounds. Using this strategy, 5-aminotetrazole-1-propionic acid (Hatzp) was selected to react with praseodymium(III) nitrate or perchlorate in the same solvent system, producing two different coordination compounds, [Pr 2 (atzp) 4 (H 2 O) 8 ] · 2NO 3 · 2H 2 O ( 1 ) and [Pr 2 (atzp) 6 (H 2 O) 2 ] · H 2 O ( 2 ). These compounds were structurally characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. X-ray diffraction analysis revealed that compound 1 displays a dinuclear structure, whereas 2 shows a one dimensional zigzag chain framework. Furthermore, the luminescence properties of compounds 1 and 2 were investigated at room temperature in the solid state.

    The effect of RHIZOMA COPTIDIS and COPTIS CHINENSIS aqueous extract on radiation-induced skin injury in a rat model (2013)
    BioMed Central
    Details
    Publication Date: 2013-05-16
    Description: Background: Radiation-induced skin injury is a common complication of radiotherapy. The RHIZOMA COPTIDIS and COPTIS CHINENSIS extract (RCE) can ameliorate radiation-induced skin injury in our clinical observation. But, the protective mechanism of RHIZOMA COPTIDIS and COPTIS CHINENSIS in radiation-induced skin injury remains unclear. Methods: In this experiment, we developed a radiation-induced skin injury rat model to study the mechanism. The animals were randomly divided into control group, treatment group, radiation group, and treatment and radiation group. 5 rats in each group were separately executed on 2 d and 49 d post-radiation. The semi-quantitative skin injury score was used to measure skin reactions by unblinded observers, and hematoxylin and eosin staining was used to evaluate the damage areas by irradiation. The MDA content, SOD activity of skin and serum were measured to detect the oxidative stress. Results: Acute skin reactions were caused by a single dose of 45 Gy of beta-ray irradiation, and the skin injury could be found in all rats receiving irradiation based on the observation of HE staining of skin at different time-points, while RCE could significantly ameliorate those changes. TheMDA content in serum and skin of control rats was 4.13 +/- 0.12mmol/ml and 4.95 +/- 0.35mmol/mgprot on 2 d post-radiation. The rats receiving radiation showed an increased content of MDA (5.54 +/- 0.21mmol/ml and 7.10 +/- 0.32mmol/mgprot), while it was 4.57 +/- 0.21mmol/ml and 5.95 +/- 0.24mmol/mgprot after treated with RCE (p 〈 0.05). Similarchanges of the MDA content could be seen on 49 d post-radiation. However, the SOD activity of rats receiving radiation decreased compared with control group on both time-points, which was inhibited by RCE (p 〈 0.05). Meanwhile, no valuable changes could befound between control group and treatment group on 2 d and 49 d. Conclusions: Our study provides evidences for the radioprotective role of RCE against radiation-induced skin damage in rats by modulating oxidative stress in skin, which may be a useful therapy for radiation-induced skin injury.

    Antifatigue properties of dragonfly Pantala flavescens wings (2014)
    Wiley-Blackwell
    Details
    Publication Date: 2014-03-14
    Description: ABSTRACT The wing of a dragonfly is thin and light, but can bear high frequent alternating stress and present excellent antifatigue properties. The surface morphology and microstructure of the wings of dragonfly Pantala flavescens were observed using SEM in this study. Based on the biological analysis method, the configuration, morphology, and structure of the vein were studied, and the antifatigue properties of the wings were investigated. The analytical results indicated that the longitudinal veins, cross veins, and membrane of dragonfly wing form a optimized network morphology and spacially truss-like structure which can restrain the formation and propagation of the fatigue cracks. The veins with multilayer structure present high strength, flexibility, and toughness, which are beneficial to bear alternating load during the flight of dragonfly. Through tensile-tensile fatigue failure tests, the results were verified and indicate that the wings of dragonfly P. flavescens have excellent antifatigue properties which are the results of the biological coupling and synergistic effect of morphological and structural factors.

    Screening for Voltage-Gated Sodium Channel Interacting Peptides (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-04-03
    Description: The voltage-gated sodium channel (VGSC) interacting peptide is of special interest for both basic research and pharmaceutical purposes. In this study, we established a yeast-two-hybrid based strategy to detect the interaction(s) between neurotoxic peptide and the extracellular region of VGSC. Using a previously reported neurotoxin JZTX-III as a model molecule, we demonstrated that the interactions between JZTX-III and the extracellular regions of its target hNav1.5 are detectable and the detected interactions are directly related to its activity. We further applied this strategy to the screening of VGSC interacting peptides. Using the extracellular region of hNav1.5 as the bait, we identified a novel sodium channel inhibitor SSCM-1 from a random peptide library. This peptide selectively inhibits hNav1.5 currents in the whole-cell patch clamp assays. This strategy might be used for the large scale screening for target-specific interacting peptides of VGSCs or other ion channels. Scientific Reports 4 doi: 10.1038/srep04569
