This study aimed to estimate the associations between air pollution and esophageal cancer. In the ecologic cross-sectional study, correlation analyses were made between city-level mean concentrations of particulate matter less than 10μm in aerodynamic diameter (PM10), SO2, NO2 and city-level age-standardized mortality rates of esophageal cancer in Shandong Province, China. PM10 (p=0.046) and NO2 (p=0.03) both had significant linear correlations with esophageal cancer mortality rates. After introducing smoking as a risk factor in models of multiple linear regression analyses, PM10 was still an independent risk factor that increased esophageal cancer mortality rates...

BACKGROUND: Circulating endometrial cells (CECs) have been reported to be present in the peripheral blood of women with endometriosis (EM), providing clear and specific evidence of the presence of ectopic lesions. In this study, we established a method with a high detection rate of CECs, assessed the diagnostic value of CECs for EM and compared with serum CA125, and proposed a hypothesis for the pathogenesis of EM from the new perspective of CECs. METHODS: The participants were enrolled prospectively from October 2015 to July 2016...

The prefrontal cortex (PFC) is the most frequently targeted brain region by non-invasive brain stimulation (NBS) studies. Non-invasively stimulating the PFC has been shown to both modulate affective processing and improve the clinical symptoms of several psychiatric disorders, such as depression and schizophrenia. The magnitude of the modulation depends on several factors, including the stimulation frequency, the number of stimulation sessions, and the specific sub-region of the PFC that is stimulated. Although some of the potential underlying mechanisms have been identified, the exact mechanisms that underlie these cognitive and affective changes remain unclear...

This study aimed to evaluate the risk of ultrasound-detected synovitis after antitumor necrosis factor (TNF) tapering in patients with rheumatoid arthritis. We recruited patients with rheumatoid arthritis who accepted TNF tapering. Gray-scale synovitis and power Doppler score in bilateral wrists at the dorsal radiolunate joint were evaluated. We defined a sum of bilateral wrist scores of ≥2 as sonographic inflammation. Logistical regression analysis was used to adjust for confounding factors. One hundred and twenty-two patients who received a tapered dose of anti-TNF were enrolled, of whom 96 (78%) had ultrasound-detected synovitis and 26 had no inflammation...

Soil organic carbon (SOC) is a major component in the global carbon cycle. Yet how input of plant litter may influence the loss of SOC through a phenomenon called priming effect remains highly uncertain. Most published results about the priming effect came from short-term investigations for a few weeks or at the most for a few months in duration. The priming effect has not been studied at the annual time scale. In this study for 815 days, we investigated the priming effect of added maize leaves on SOC decomposition of two soil types and two treatments (bare fallow for 23 years, and adjacent old-field, represent stable and relatively labile SOC, respectively) of SOC stabilities within each soil type, using a natural 13C-isotope method...

Influenza viruses cause severe upper respiratory illness in young children and the elderly during seasonal epidemics. Influenza viruses also have the potential to cause pandemics with significant loss of life in all age groups. Although vaccination is one of the most effective methods to protect against seasonal epidemics, seasonal vaccines afford lowered protection against emerging variant strains and no protection against novel strains. Moreover, the efficacy of influenza virus vaccines is considerably lower in the elderly population...

Survival of mosquitoes from dengue virus (DENV) infection is a prerequisite of viral transmission to the host. This study aimed to see how mosquito cells can survive the infection during prosperous replication of the virus. In C6/36 cells, global protein translation was shut down after infection by DENV type 2 (DENV2). However, it returned to a normal level when infected cells were treated with an inhibitor of the protein kinase RNA (PKR)-like ER kinase (PERK) signaling pathway. Based on a 7-Methylguanosine 5'-triphosphate (m7GTP) pull-down assay, the eukaryotic translation initiation factor 4F (eIF4F) complex was also identified in DENV2-infected cells...

The coexistence of immunoglobulin A nephropathy (IgAN) and idiopathic membranous nephropathy (IMN) in a few cases suggested that there could be existed a similar mechanism in pathogenesis of these two types of primary glomerulonephritis. In order to verify this hypothesis, a total of 23 reported IgAN-associated SNPs were genotyped in a cohort of 485 IMN patients and 569 healthy controls with Chinese Han origin. After Cochran-Armitage test for trend analysis, seven IgAN-associated SNPs located in the major histocompatibility complex (MHC) region were found to be significantly associated with the susceptibility of IMN, with rs9275596 as the top one (p = 1...

Porcine contagious pleuropneumonia is a highly fatal respiratory disease that is caused by Actinobacillus pleuropneumoniae (APP) and results in tremendous economic losses for the pig breeding industry worldwide. Previous studies have demonstrated that Propionibacterium acnes (PA) could effectively prevent APP infection in mice and pigs. The humoral immune response played a primary role during this process and anti-PA antibody could mediate macrophages to kill the bacteria. However, the role of neutrophils in this process is currently unknown...

Long non-coding RNAs (lncRNAs) serve an important role in numerous human diseases, including cancer. Abnormal expression of lncRNAs has been associated with a number of tumor types; however, the underlying mechanisms through which lncRNA functions have yet to be elucidated. The present study primarily focuses on insulin-like growth factor 2 antisense 1 (Igf2as), a lncRNA reported to be differentially expressed in hepatocellular carcinoma (HCC). Reverse transcription-quantitative polymerase chain reaction analysis was used to determine the level of Igf2as in HCC cells and tissues...

Epilepsy and spreading depolarization (SD) are both episodic brain disorders and often exist together in the same individual. In CA1 pyramidal neurons of mouse hippocampal slices, induction of SD evoked epileptiform activities, including the ictal-like bursts, which occurred during the repolarizing phase of SD, and the subsequent generation of paroxysmal depolarization shifts (PDSs), which are characterized by mild depolarization plateau with overriding spikes. The duration of the ictal-like activity was correlated with both the recovery time and the depolarization potential of SD, whereas the parameters of PDSs were not significantly correlated with the parameters of SD...

The genetic basis of body shape and coloration patterns on caterpillars is often assumed to be regulated separately, but it is possible that common molecules affect both types of trait simultaneously. Here we examine the genetic basis of a spontaneous cuticle defect in silkworm, where larvae exhibit a bamboo-like body shape and also decreased pigmentation. We performed linkage mapping and mutation screening to determine the gene product that affects body shape and coloration simultaneously. In these mutant larvae we identified a null mutation in BmorCPH24, a gene encoding a cuticular protein with low complexity sequence...

A series of 1,4-naphthoquinones (10a-10q) were synthesized and evaluated for anticancer activity. Compound 10e was identified as an inhibitor of Itch, a HECT domain-E3 ligase. In an evaluation of in vivo efficacy, 10e exhibited remarkable anticancer activity with TGI values of 98.3% and 100% at 25 mg/kg and 50 mg/kg orally daily, respectively, against human RPMI-8226 multiple myeloma xenograft. Treatment with 10e also showed a decrease of Itch level in human RPMI-8226 multiple myeloma cells. Thus 10e is a lead compound for further development of inhibitors targeting E3 ligase for treatment of multiple myeloma...
