The "obesity paradox" reflects an observed relationship between obesity and decreased morbidity mortality, suggesting improved health outcomes for obese individuals. Studies examining the high body mass index (BMI) adverse after cardiac surgery have reported conflicting results.The study population (N=78 762) was comprised of adult patients who had undergone first-time coronary artery bypass (CABG) or combined CABG/aortic valve replacement (AVR) from April 1, 1998 to October 31, 2011 in...

Abstract Long noncoding RNA s (lnc s), a novel class of transcripts that have critical roles in carcinogenesis and progression, emerged as important gene expression modulators. Recent evidence indicates lnc taurine‐upregulated 1 ( TUG 1) functions an oncogene numerous types human cancers. However, its function the development cervical cancer remains unknown.

<h3>Objective</h3> Tumour biomarkers are used as indicators for cancer screening and predictors therapeutic responses prognoses in patients. We aimed to identify genetic loci that influence concentrations of antigen 19-9 (CA19-9), carcinoembryonic (CEA) α fetoprotein (AFP), investigated the associations between significant single nucleotide polymorphisms (SNPs) with risks oesophageal squamous cell (OSCC), pancreatic hepatocellular cancers. <h3>Design</h3> carried out a genome wide...

Abstract We propose a nonparametric method to assess the effects of one or more covariates on cure rate for survival data with fraction. The extends existing work single sample and multiple cases also allows continuous covariate. proposed estimator is shown be consistent asymptotically normal. A simulation study shows that estimates covariate effect smaller biases than semi‐parametric models, particularly when models mis‐specify effect. applied leukaemia patients age chance being cured after...

Abstract This study focuses on the sources of organic carbon (OC) in surface sediments reservoirs mountainous regions, as well their dynamics and contribution mechanisms cycle. Spatial variations carbon, n‐alkanes, δ 13 C, 15 N were analyzed, a Bayesian isotope mixing model was applied to quantify relative contributions different OC sources. The results indicate that concentration range is 0.88%–3.72%. average long‐chain n‐alkanes 3.69 μg/g, accounting for 71.4%, indicating main source...

Abstract Hydrologic regimes are affecting terrestrial carbon transformation, chemical weathering and lateral transport. However, its impacts on dissolved export patterns remains elusive. In this study, we collected a 2‐year high‐frequency inorganic (DIC) organic (DOC) dataset, namely wet year (Rainfall = 1,158 mm) dry 603 mm). The results showed that drought led to significant decrease in concentration discharge during the monitoring period. During non‐storm periods, DIC DOC shifted from...

The present study was carried out to investigate the hypothesis that organic nitrates can attenuate senescence of mesenchymal stem cells (MSCs), a superior cell source involved in regeneration and repair damaged tissue. MSCs were treated with high glucose (HG) order induce senescence, which markedly attenuated by pre-treatment isosorbide dinitrate (ISDN), commonly used nitrate, as indicated senescence-associated galactosidase (SA-β-gal) activity, p21 expression, well mRNA levels DNA...

Abstract Death domain-associated protein (DAXX) is a complex biological multifunctional and involved in the tumorigenesis progression of multiple cancers. The accumulation DAXX nucleus common phenomenon tumor cells. However, altering subcellular localizations results different functions, we also found that its nuclear/cytoplasmic ratio (NCR) was associated with poor prognosis gastric cancer (GC). In this study, investigated effect cytoplasmic nuclear (cDAXX nDAXX) GC underlying mechanisms....

Colorectal cancer (CRC) is one of the deadliest tumours, but its pathogenesis remains unclear. The involvement differentially expressed long non-coding RNAs (lncRNAs) in CRC tumorigenesis makes them suitable tumour biomarkers.Here, we screened 150 cases and 85 paracancerous tissues GEO database for lncRNAs. levels lncRNA candidates 84 tissue samples were validated by qRT-PCR their clinical significance was analyzed. We identified 15 lncRNAs with differential expression tumours; among them,...

Non-point source nitrogen loss poses a risk to sustainable aquatic ecosystems. However, non-point sources, as well impaired river segments with high concentrations, are difficult monitor and regulate because of their diffusive nature, budget constraints, resource deficiencies. For the purpose catchment management, Bayesian maximum entropy approach spatial regression models have been used explore spatiotemporal patterns loss. In this study, total 18 sampling sites were selected along network...
