A simple and effective method to enrich endogenous DNA from mammalian faeces.

Utilization of faeces has long been a popular approach for genetic and ecological studies of wildlife. However, the success of molecular marker genotyping and genome resequencing is often unpredictable due to insufficient enrichment of endogenous DNA in the total faecal DNA that is dominated by bacterial DNA. Here, we report a simple and cheap method named PEERS to predominantly lyse animal cells over bacteria by using sodium dodecyl sulphate so as to discharge endogenous DNA into liquid phase before bacterial DNA.

Combined PLT and NE to predict the prognosis of patients with locally advanced cervical cancer.

Cervical cancer is one of the most common tumors in women. Neutrophils (NEs) and platelets (PLTs) are components of cells in circulating blood. NEs are one of the components of white blood cells (WBCs), accounting for the vast majority of WBCs, recognized as one of the indicators of inflammation.

Prognostic Values of LDH and CRP in Cervical Cancer.

Purpose: Cervical cancer is one of the deadliest tumors among women in China. C-reactive protein (CRP), an indicator of inflammation, and lactate dehydrogenase (LDH), an enzyme ubiquitously expressed in cells, both play important roles in tumor growth and metastasis.

Patients And Methods: Based on pre-radiotherapy LDH and CRP median levels, we divided patients into four groups: high LDH and CRP group, high LDH group, high CRP group, and low LDH and CRP group.

UV-Visible Photodetector Based on I-type Heterostructure of ZnO-QDs/Monolayer MoS.

Monolayer MoS has shown excellent photoresponse properties, but its promising applications in high-sensitivity photodetection suffer from the atomic-thickness-limited adsorption and band gap-limited spectral selectivity. Here we have carried out investigations on MoS monolayer-based photodetectors with and without decoration of ZnO quantum dots (ZnO-QDs) for comparison. Compared with monolayer MoS photodetectors, the monolayer ZnO-QDs/MoS hybrid device exhibits faster response speed (1.

[Optimization of intra-vascular stent designs].

The finite element method introduced in this paper is used to simulate the expanded stents shapes and the whole expansion process of the stents with different designs, in order to calculate their radial displacements and deformation stress levels, thus to get the optimization of stent structural designs.
