BACKGROUND: Beside the phosphate binding effect, non-calcium non-aluminum phosphate binder, namely sevelamer hydrochloride (SH), has many other effects in dialysis patients. It can absorb many other compounds, decrease low-density lipoprotein cholesterol (LDL-C) level, and attenuate the progression of vascular calcification; it has been reported to have anti-inflammatory effect. However, it is not clear whether it has any effect on uremic toxins, i.e. serum indoxyl sulfate (IS) and p-cresyl sulfate, (PCS) in hemodialysis (HD) patients...

Probing electrodes at a nanometer scale is challenging but desirable to reveal the structural evolution of materials in electrochemical reactions. Herein, we present an atomic force microscopic method for an in situ analysis of a single Sn nanoparticle during sodiation and desodiation, which is conducted in an aprotic liquid electrolyte akin to a real electrochemical environment of the Na-ion cells. The morphological evolution of different-sized single Sn nanoparticle is visualized during the charge/discharge cycles by using a homemade planar electrode...

Oxidative stress-induced growth inhibitor 1 (OSGIN1), a tumor suppressor, inhibits cell proliferation and induces cell death. N-6 and n-3 PUFAs protect against breast cancer, but the molecular mechanisms of this effect are not clear. We investigated the effect of n-6 and n-3 PUFAs on OSGIN1 expression and whether OSGIN1 is involved in PUFA-induced apoptosis in breast cancer cells. We used 100 μM of n-6 PUFAs including arachidonic acid, linoleic acid, and gamma-linolenic acid and n-3 PUFAs including alpha-linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid (DHA)...

C1q/tumor necrosis factor-related protein-3 (CTRP3) is an adipokine that protects against myocardial infarction-induced cardiac dysfunction through its pro-angiogenic, anti-apoptotic, and anti-fibrotic effects. However, whether CTRP3 can directly affect the systolic and diastolic function of cardiomyocytes remains unknown. Adult rat cardiomyocytes were isolated and loaded with Fura-2AM. The contraction and Ca(2+) transient data was collected and analyzed by IonOptix system. 1 and 2μg/ml CTRP3 significantly increased the contraction of cardiomyocytes...

The pathophysiological function of the forkhead transcription factor FOXN3 remains to be explored. Here we report that FOXN3 is a transcriptional repressor that is physically associated with the SIN3A repressor complex in estrogen receptor-positive (ER+) cells. RNA immunoprecipitation-coupled high-throughput sequencing identified that NEAT1, an estrogen-inducible long noncoding RNA, is required for FOXN3 interactions with the SIN3A complex. ChIP-Seq and deep sequencing of RNA genomic targets revealed that the FOXN3-NEAT1-SIN3A complex represses genes including GATA3 that are critically involved in epithelial-to-mesenchymal transition (EMT)...

Lysine crotonylation (Kcr) is a newly identified histone modification that is associated with active transcription in mammalian cells. Here we report that the chromodomain Y-like transcription corepressor CDYL negatively regulates histone Kcr by acting as a crotonyl-CoA hydratase to convert crotonyl-CoA to β-hydroxybutyryl-CoA. We showed that the negative regulation of histone Kcr by CDYL is intrinsically linked to its transcription repression activity and functionally implemented in the reactivation of sex chromosome-linked genes in round spermatids and genome-wide histone replacement in elongating spermatids...

Iodine-rich herbs such as seaweed, kelp, and sea tangle were widely used to treat various types of goiter with good effect and without any adverse side effects in China. When compared with potassium iodate (PI), iodine-rich herbs had a positive effect on the recovery of goiter resulting from iodine deficiency without any obvious harmful effects. In NOD.H-2(h4) mice, an autoimmune thyroiditis-prone model, iodine excess can increase infiltration of lymphocytes and structural damage of the thyroid follicles, hence resulting in thyroiditis...

Cancer cells display altered glucose metabolism characterized by a preference for aerobic glycolysis. The aerobic glycolytic phenotype of hepatocellular carcinoma (HCC) is often correlated with tumor progression and poorer clinical outcomes. However, the issue of whether glycolytic metabolism influences metastasis in HCC remains unclear. In the current study, we showed that knockdown of Taurine upregulated gene 1 (TUG1) induces marked inhibition of cell migration, invasion and glycolysis via suppression of miR-455-3p...

The exact pathophysiology of interstitial cystitis/painful bladder syndrome is unknown; however, autoimmunity is a valid theory. We developed an autoimmune chronic cystitis model by administration of the medium dose of immunogenic peptide T2. Sixty female C57BL/6 mice were divided into six groups. The control group was not treated with any reagent. CFA group was injected with CFA + normal saline, homogenate group with bladder homogenate + CFA, low-dose group with low dose of T2 peptide + CFA, medium dose group with the medium dose of T2 peptide + CFA, and high-dose group with the high dose of T2 peptide + CFA...

Early-life stress in adolescence has a long-lasting influence on brain function in adulthood, and it is mostly recognized as a predisposing factor for mental illnesses, such as anxiety and posttraumatic stress disorder. Previous studies also indicated that adolescent predictable chronic mild stress (PCMS) in early life promotes resilience to depression- and anxiety-like behaviors in adulthood. However, the role of PCMS in associated memory process is still unclear. In the present study, we found that adolescent PCMS facilitated extinction and inhibited fear response in reinstatement and spontaneous recovery tests in adult rats, and this effect was still present 1 week later...

The purpose of this study was to investigate the anticancer activity of polysaccharide (PGL) from Glehnia littoralis on human lung cancer cell line A549. Based on MTT assay, the results suggested that PGL could significantly reduce A549 cells proliferation in a time- and dose-dependent manner. In addition, PGL displayed an inhibitory activity for the A549 cells migration in Transwell migration assay. The results from both flow cytometry analysis and Hochst 3342 staining of apoptotic cells indicated that PGL could promote apoptosis, and induce cycle arrest of A549 cells...

Membrane fouling is the bottleneck that restricts the sustainability of membrane technology for environmental applications. Therefore, the development of novel analytical tools for characterizing membrane fouling processes is essential. In this work, we demonstrate a capability of probing the chemical structure of foulants and detecting their 3-dimentional spatial distribution on membranes based on stimulated Raman scattering (SRS) microscopy as a vibrational spectroscopic imaging approach. The adsorption process of foulants onto membrane surfaces and their aggregation process within membrane pores during the micro-filtration of protein and polysaccharide solutions were clearly monitored...
