Spatially selective p-type doping for constructing lateral WS p-n homojunction via low-energy nitrogen ion implantation.

The construction of lateral p-n junctions is very important and challenging in two-dimensional (2D) semiconductor manufacturing process. Previous researches have demonstrated that vertical p-n junction can be prepared simply by vertical stacking of 2D materials. However, interface pollution and large area scalability are challenges that are difficult to overcome with vertical stacking technology.

Functional analysis of low-grade glioma genetic variants predicts key target genes and transcription factors.

Background: Large-scale genome-wide association studies (GWAS) have implicated thousands of germline genetic variants in modulating individuals' risk to various diseases, including cancer. At least 25 risk loci have been identified for low-grade gliomas (LGGs), but their molecular functions remain largely unknown.

Methods: We hypothesized that GWAS loci contain causal single nucleotide polymorphisms (SNPs) that reside in accessible open chromatin regions and modulate the expression of target genes by perturbing the binding affinity of transcription factors (TFs).

The Cancer-Associated Genetic Variant Rs3903072 Modulates Immune Cells in the Tumor Microenvironment.

Genome-wide association studies (GWAS) have hitherto identified several germline variants associated with cancer susceptibility, but the molecular functions of these risk modulators remain largely uncharacterized. Recent studies have begun to uncover the regulatory potential of noncoding GWAS SNPs using epigenetic information in corresponding cancer cell types and matched normal tissues. However, this approach does not explore the potential effect of risk germline variants on other important cell types that constitute the microenvironment of tumor or its precursor.

[Analysis on pathogen detection for 53 influenza outbreaks].

Objective: In order to provide a scientific basis for influenza prevention and control, analyzing the epidemic characteristics and laws of influenza outbreaks in Xuzhou area during 2005-2011.

Method: Using fluorescent-PCR method to detect influenza virus nucleic acid on Nasopharyngeal swab specimens collected from influenza outbreak cases during 2005-2011 and fast classifying influenza virus A1 (H1N1), A3 (H3N2), new H1N1 BV (Victoria) and BY (Yamagate) on subtypes. At the same time, isolating the influenza virus with MDCK cells, and sending them to the National Influenza Center for review, after the preliminary identification of the isolated influenza virus.

[Etiological analysis of influenza surveillance data in Xuzhou from 2005 to 2011].

Objective: To investigate the prevalence and subtypes of influenza viruses in Xuzhou city from 2005 to 2011 and to provide the scientific supports for influenza prevention and control in this religion.

Methods: The throat swab samples were collected from the influenza-like cases from national influenza like illness sentinel hospital in Xuzhou. The samples were used for influenza virus isolation and identification, sent on the national flu center to confirm according to the "national influenza surveillance program" and "influenza virus and experimental technology".

[Research on the aetiology of suspected enterovirus infected patients in Xuzhou district in 2009].

Objective: To understand and master the situation in which enterovirus caused hand-foot-and-mouth disease (HFMD) in Xuzhou district in 2009 so as to provide scientific basis for the control and prevention of hand-foot-and-mouth disease.

Methods: The researchers adopted fluorescence RT-PCR method to detect EV and EV71 as well as the CA16 specificity RNA from 222 samples of anal swabs and oropharyngeal swabs from the 240 cases who were diagnosed clinically as hand-foot-mouth disease infected by enterovirus. Also, the researchers conducted EV71-IgM antibody detection on 114 samples of acute phase serum with ELA method.
