Objective: To identify a good combination model for predicting the mortality of lung cancer.
Methods: Mortality data of lung cancer from 2001-2013 were used to test three prediction model: dynamic series, exponential smoothing, and Joinpoint regression. Weight coefficients of the combination models were calculated using the arithmetic average method, the variance inverse method, the mean square error inverse method, and the simple weighted average method.
Introduction: Inadequate trophoblast invasion and placentation are widely believed to contribute to preeclampsia, and multiple lines of evidence indicate the involvement of hypoxia in preeclampsia. However, the molecular mechanisms underlying the association of placental hypoxia with preeclampsia are not clear.
Material And Methods: The present study focused on the role in preeclampsia of heme oxygenase 1 (HO-1), which is an inducible isoform of HO in response to hypoxia, via examining the expression of HO-1 and the expression and phosphorylation (Tyr705) of Signal transducer and activator of transcription (STAT) 3 in preeclamptic placentas via the immunohistochemical method, western blotting assay and RT-qPCR method.
The emergence and spread of antibiotic resistance has posed a major threat to both human health and environmental ecosystem. Although the disinfection has been proved to be efficient to control the occurrence of pathogens, little effort is dedicated to revealing potential impacts of disinfection on transmission of antibiotic resistance genes (ARGs), particularly for free-living ARGs in final disinfected effluent of urban wastewater treatment plants (UWWTP). Here, we investigated the effects of chlorine disinfection on the occurrence and concentration of both extracellular ARGs (eARGs) and intracellular ARGs (iARGs) in a full-scale UWWTP over a year.

A hypoxic environment develops in the placenta after the 10th week of pregnancy and exerts a major influence over trophoblast activity. In the present study, we investigated expression of miR-222 and apoptosis-related BCL2L11 in preeclampsia placenta and in primary placenta mesenchymal stem cells (MSCs) under hypoxia.

However, the detection of disinfectant-injured or genetically modified (GM) E. coli has been largely overlooked so far.

Methods: Mortality data were collected from company departments through administrative documents, death certificates, etc. Trend analyses of cancer mortality were performed on the basis of 925 cancer deaths between 2001 and 2010.

The relationship between tyrosine phosphorylation (TP) and protein expression of insulin receptor (InsR) and insulin resistance (IR) in patients with gestational diabetes mellitus (GDM) was investigated. The InsR expression and TP in skeleton muscle tissue were determined by Western blotting and immunoprecipitation in women with GDM (GDM group, n=22), normal pregnant women (normal pregnancy group, n=22) and normal non-pregnant women (normal non-pregnant group, n=13). Fasting plasma glucose (FPG) and fasting insulin (FINS) were measured by oxidase assay and immunoradioassay.

Earlier research indicating that altered immunity exists in unexplained recurrent miscarriage (RM) has been dominated by the Th1/Th2 hypothesis. Recently, the Th1/Th2 paradigm has been expanded into the Th1/Th2/Th17 and regulatory T cells paradigm.

We could identify the bacterium as being a Bacillus sp., based on morphological observation, physiological characteristics, and 16S rDNA sequence analysis, thus leading us to designate the strain as Bacillus sp.
