Studying thermotolerance is important for the prevention of thermostress in chickens. This study aimed to analyze the effect of mutations in the heat shock protein 70 (HSP70) gene on chicken thermotolerance. The C.-69A>G SNP in the 5'-flanking region of the HSP70 gene was genotyped in Lingshan and White Recessive Rock (WRR) chickens. Association of this SNP with thermotolerance traits revealed ...

PURPOSE Some studies have investigated the association of IL-2 -330T/G (rs2069762) polymorphism with cancer risk, but the previous results were conflicting and had relatively low statistical power. Thus, we performed a meta-analysis to derive a more precise estimation of the association between IL-2 -330T/G polymorphism and cancer risk. METHODS A literature search was performed systematically...

In this paper, we carry out the next-to-leading-order QCD corrections to $Z \to \eta_Q+g+g~(Q=c,b)$ (labeled as $gg$) through color-singlet (CS) state of $Q\bar{Q}[^1S_0^{[1]}]$, with aim assessing impact process on $Z$ bosons decaying into inclusive $\eta_Q$. We find that $gg$ can notably enhance its leading-order results, especially for $\eta_c$ case, which would then greatly increase existin...

ADIPOQ gene polymorphisms have been indicated to be associated with hypertension; however, published studies have reported inconsistent results. Eligible studies were retrieved by searching the PubMed, Embase and China National Knowledge Infrastructure databases. The case group consisted of patients with hypertension, and the control group consisted of subjects with normal blood pressure. Based...

Background: Valid measures of asthma and eczema in epidemiological studies may be a challenge. Population-based registers can be useful as they do not rely on recall and allow for follow-up. Our aim was to ascertain if asthma/eczema medication is a suitable proxy for asthma/ eczema and to validate register-based asthma diagnoses. Method: Data were retrieved on all 0-17-year-old individuals with...

BACKGROUND The aim of this study was to investigate the possible associations of miRNA-27a and Leptin polymorphisms with the risk of recurrent spontaneous abortion (RSA). MATERIAL AND METHODS Between May 2013 and April 2015 at Shenzhen Longhua New District Central Hospital, we randomly recruited 138 RSA patients as the case group and another 142 normal pregnancy women as the control group. We u...

UNLABELLED Toll-like receptor 4 (TLR4) is potentially an important gene affecting the susceptibility to type 2 diabetes mellitus (T2DM). The objective of this study was to evaluate whether genetic polymorphisms of the TLR4 gene are associated with T2DM susceptibility. This potential association was analyzed in 668 T2DM patients and 672 healthy controls by polymerase chain reaction-restriction f...

BACKGROUND As a common malignant tumor, gastric carcinoma requires early diagnosis to improve treatment efficacy. MicroRNA (miR) molecules have highly conserved nucleotide sequences and can negatively regulate target gene expression at the translational level. miR-421 has been suggested to be related with gastric cancer occurrence. The gene polymorphism of miR-421, however, has not been reporte...

Several studies suggest an important role of Acyl-CoA: cholesterol acyltransferase-1(ACAT-1) in the development of atherosclerosis. The aim of present study was to investigate whether there exists a possible correlation between genetic variations in ACAT-1 genes and coronary artery disease (CAD) risk. Four polymorphisms (rs1044925, rs11545566, rs12121758 and rs10913733) were finally selected an...
