An Integrative Transcriptome Analysis Reveals Consistently Dysregulated Long Noncoding RNAs and Their Transcriptional Regulation Relationships in Heart Failure.

Accumulating evidence suggests that long noncoding RNAs (lncRNAs) are emerging as important regulators involved in diseases, including heart failure (HF). In this study, we used microarray profiles to examine the transcriptome of lncRNAs in left ventricle samples derived from HF patients. We designed a custom pipeline to reannotate lncRNAs from microarray data and identified a set of consistently dysregulated lncRNAs in HF across the three independent cohorts.

Preparation of a Two-Dimensional Ion-Imprinted Polymer Based on a Graphene Oxide/SiO₂ Composite for the Selective Adsorption of Nickel Ions.

In the present work, a novel two-dimensional (2D) nickel ion-imprinted polymer (RAFT-IIP) has been successfully synthesized based on the graphene oxide/SiO2 composite by reversible addition-fragmentation chain-transfer (RAFT) polymerization. The imprinted materials obtained are characterized by Fourier transmission infrared spectrometry (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The results show that the thermal stability of the graphene oxide/SiO2 composite is obviously higher than that of graphene oxide.

[Extract of Herba Siegesbeckiae on mouse rheumatoid arthritis induced by anthrogen-CIA monoclonal antibody].

Objective: To investigate the anti-inflammatory effect of Herba Siegesbeckiae extracts on mouse rheumatoid arthritis induced by arthrogen-CIA monoclonal antibody.

Methods: The rheumatoid arthritis was induced by arthrogen-CIA arthritogenic monoclonal antibody in mice. The sandwich enzyme-linked immunosorbent assay was used to determine the concentration of IL-1βin mouse serum,and the content of IL-6,IL-17 and MMP-3 in supernatant of tissue homogenate of hind limb below the stifle of mice.

A potential role for macrophages in maintaining lipopolysaccharide-induced subacute airway inflammation in rats.

Bacterial infection is a key factor in airway inflammation. The present study describes the time-dependent changes in the leukocyte counts and cytokine levels of the bronchoalveolar lavage fluid (BALF) following subacute airway inflammation induced by lipopolysaccharide (LPS), a major component of the outer membranes of Gram-negative bacteria. LPS (200 μg/rat) or saline was intratracheally administered to rats which were sacrificed 2, 4 or 7 days after LPS treatment.
