Apelin, an endogenous ligand for apelin receptor (APJ), is reported to be involved in cardiomyocyte hypertrophy. In this study, we explored the mechanism of cardiomyocyte hypertrophy induced by apelin-13/APJ system. Left ventricular hypertrophy (LVH) rat model was established by constricting the abdominal aorta. Western blots were used for protein expression in LVH rats and cultured H9c2 cardiomyocytes. Transmission electron microscopy (TEM) was used to monitor morphological features of cells. In addition, the diameter and volume of H9c2 cells were detected by Scepter™ Handheld Automated Cell Counter...

The aim of the present study was to investigate the prognostic significance of stromal interaction molecule 1 (STIM1) expression in gastric cancer (GC) and examine the association between STIM1 and epithelial‑mesenchymal transition (EMT). Immunohistochemical staining was performed to detect STIM1, E‑cadherin, β‑catenin and matrix metalloproteinase‑9 (MMP‑9) in 170 GC and 35 adjacent healthy gastric tissue samples. Positive staining of STIM1, E‑cadherin, β‑catenin and MMP‑9 in GC tissues was significantly greater compared with adjacent healthy tissues (P<0...

It is now commonly known that exposure to polybrominated diphenyl ethers (PBDEs) may cause neurotoxicity and cognitive deficits in children as well as adults, but the underlying mechanisms are still not clear. In the present study, we aimed to elucidate the potential underlying mechanism of 2, 2', 4, 4'-tetrabromodiphenyl ether (BDE-47)-induced neurotoxicity and cognitive impairment. Our results showed that BDE-47-treated mice exhibited impaired cognition and robust upregulation of nuclear TDP-43 in the hippocampus...

Corylifol A, a member of the isoflavone subclass of isoflavonoids, has long been considered to have various biological activities. Here, we sought to synthesize corylifol A glucosides by the in vitro glucosylation reaction using the UDP-glycosyltransferase YjiC from Bacillus licheniformis DSM 13, and obtained two novel glucosides: corylifol A-4',7-di-O-beta-d-glucopyranoside (1) and corylifol A-4'-O-beta-d-glucopyranoside (2). To improve the yield of the products, the reaction time, concentration of UDP-glucose, and pH of the buffer were optimized...

The present study was designed to perform structural modifications of of neobavaisoflavone (NBIF), using an in vitro enzymatic glycosylation reaction, in order to improve its water-solubility. Two novel glucosides of NBIF were obtained from an enzymatic glycosylation by UDP-glycosyltransferase. The glycosylated products were elucidated by LC-MS, HR-ESI-MS, and NMR analysis. The HPLC peaks were integrated and the concentrations in sample solutions were calculated. The MTT assay was used to detect the cytotoxic activity of compounds in cancer cell lines...

An acid-promoted multicomponent reaction for the synthesis of diverse fully substituted oxazole derivatives from simple and readily available arylglyoxal monohydrates, nitriles and various C-nucleophiles has been developed. This protocol features wide functional group diversity which is capable of installing 4-hydroxycoumarin, 2-naphthol and 1,3-cyclohexanedione motifs to oxazoles. Mechanistic analysis indicates that a classical Robinson-Gabriel reaction served as the key step for this tandem transformation...

Parkinson's disease (PD) and Parkinsonism are common neurodegenerative disorders with continuously increasing prevalence, causing high global burdens. However, data concerning the comorbidity burden of patients with PD or Parkinsonism in China are lacking. To investigate the health condition and comorbidity burden, a total of 3367 PD and 823 Parkinsonism patients were included from seven tertiary hospitals in seven cities across China from 2003 to 2012. Their comorbidity burden was collected and quantified by the Elixhauser Comorbidity Index (ECI) and Charlson Comorbidity Index (CCI)...

We demonstrate a hetero-structure Ni9S8/MoS2 hybrid with tight interface synthesized via an improved hydrothermal method. As compared to pure MoS2, the increased surface area and the shorten charge transport pathway in the layered hybrid significantly promote the photocatalytic efficiency for hydrogen evolution reaction (HER). In particularly, the optimized Ni9S8/MoS2 hybrid with 20 wt% Ni9S8 exhibits the highest photocatalytic activity with HER value of 406 μmolg-1h-1, which is enhanced by 70% compared to that of pure MoS2 nanosheets (285...

In recent years, researchers have increased attentions to the morphological brain network, which is generally constructed by measuring the mathematical correlation across regions using a certain morphometric feature, such as regional cortical thickness and voxel intensity. However, cerebral structure can be characterized by various factors, such as regional volume, surface area, and curvature. Moreover, most of the morphological brain networks are population-based, which has limitations in the investigations of individual difference and clinical applications...

Hematosepsis is a systemic inflammatory response syndrome (SIRS) with suspected or confirmed infection, which is the most common infectious disease in clinical neonatal intensive care unit. As the rapid development of neonatal hematosepsis caused by various basic diseases, the mortality rate is high, and there are some sequelae.We report the lasted study to date with 96 cases from Fujian Longyan First Hospital between 2013 and 2015. The aim of our study is to explore the value of soluble cluster of differentiation 14 subtype (sCD14-ST) in whole blood for differential diagnosis of neonatal hematosepsis at an early stage, and used in evaluation of the severity about sepsis combined with acute physiology and chronic health evaluation II (APACHE-II) score, procalcitonin (PCT), C reactive protein (CRP), and leukocyte (WBC)...

Tick-borne encephalitis (TBE) has become an increasing public health threat in recent years, ranging from Europe, through far-eastern Russia to Japan and northern China. However, the neglect of its expansion and scarce analyses of the dynamics have made the overall disease burden and the risk distribution of the disease being unclear in mainland China. In this study, we described epidemiological characteristics of 2117 reported human TBE cases from 2006 to 2013 in mainland China. About 99% of the cases were reported in forest areas of northeastern China, and 93% of reported infections occurred during May-July...

A pandemic of metabolic diseases, consisting of type-2 diabetes, non-alcoholic fatty liver diseases (NAFLD) and obesity, has imposed critical challenges for societies worldwide, prompting investigation of underlying mechanisms and exploration of low cost and effective treatment. In this report, we demonstrate that metabolic disorders in mice generated by feeding with a high-fat diet without dietary vitamin D (HD) can be prevented by oral administration of polycationic amine resin. Oral administration of cholestyramine , but not the control uncharged polystyrene, was able to sequester negatively charged bacterial endotoxin in the gut, leading to (1) reducing plasma endotoxin levels, (2) resolving systemic inflammation and hepatic steatohepatitis,and (3) improving insulin sensitivity...

RIPK3 mediates cell death and regulates inflammatory responses. Although genetic studies have suggested that RIPK3-MLKL-mediated necroptosis leads to embryonic lethality in Fadd or Caspase-8-deficient mice, the exact mechanisms are not fully understood. Here, we generated Ripk3 mutant mice by altering the RIPK3 kinase domain (Ripk3(Δ/Δ) mice), thus abolishing its kinase activity. Ripk3(Δ/Δ) cells were resistant to necroptosis stimulation in vitro, and Ripk3(Δ/Δ) mice were protected from necroptotic diseases...
