Objective: To explore the changes of cerebral white matter diffusion tensor in epilepsy.
Methods: This study was a retrospective study based on diffusion tensor imaging (DTI). Twenty-six epileptic patients and 42 normal controls matched for sex, age and handedness were enrolled in our research.
The t(8;21) fusion product, AML1/ETO, and hypoxia-inducible factor 1α (HIF1α) form a feed-forward transcription loop that cooperatively transactivates the DNA methyltransferase 3a gene promoter that leads to DNA hypermethylation and drives leukemia cell growth. Suppression of the RNA N-methyladenosine (mA)-reader enzyme YTH N-methyladenosine RNA binding protein 2 (YTHDF2) specifically compromises cancer stem cells in acute myeloid leukemia (AML) but promotes hematopoietic stem cell expansion without derailing normal hematopoiesis. However, the relevance of expression between AML1/ETO-HIF1α loop and YTHDF2, and its functional relationship with t(8;21) AML have not been documented.

A 3D model of MLNs was constructed from a Chinese Visible Human female dataset. Image registration and fusion between reconstructed MLNs and original chest computed tomography (CT) images was conducted in the Eclipse™ treatment planning system (TPS).

However, the long-term effects of TACE are unsatisfactory, as the microenvironment following procedure stimulates tumor angiogenesis, which promotes recurrence and metastasis of residual tumors. Tumor associated macrophages (TAMs) have been revealed to stimulate tumor growth and angiogenesis associated with poor prognosis in HCC.

Because S-layer proteins self-assemble into a native-like S-layer crystalline structure in vitro, they are attractive building blocks in nanotechnology. Here, the potential use of the S-layer protein EA1 from Bacillus anthracis in constructing a functional nanostructure is investigated, and apply this nanostructure in a proof-of-principle study for serological diagnosis of anthrax.

Methods: Thirty UC specimens taken by colonoscopy from patients with active UC treated at the Department of Pathology, Central Hospital Affiliated to Shenyang Medical College from February 2010 to January 2012 were included in an experimental group, and 30 normal colon tissue samples taken by colonoscopy from non-UC patients were included in a control group. Expression of TF and TFPI in UC and normal colon tissue samples was detected by immunohistochemistry.
Background: It is widely known that castration has a significant effect on the accumulation of adipose tissue. microRNAs (miRNAs) are known to be involved in fat deposition and to be regulated by the androgen-induced androgen receptor (AR). However, there is little understanding of the relationship between miRNAs and fat deposition after castration.

Protein glycosylation plays important roles not only in eukaryotes but also in prokaryotes. To further understand the roles of protein glycosylation in prokaryotes, we developed a lectin binding assay to screen glycoproteins on an Escherichia coli proteome microarray containing 4,256 affinity-purified E.

Objective: To provide data on alcohol consumption and drug use among middle-school students aged 13-15 in 4 cities of China, and to provide evidence for developing intervention strategies on adolescents alcohol and drug use.
Methods: Standardized sample selection process of two-stage cluster-sampling was used in middle-school students in Beijing, Hangzhou, Wuhan and Urumchi. A self-administered questionnaire survey was conducted in Sept.
Dissociation of biotin from streptavidin is very difficult due to their high binding affinity. The re-use of streptavidin-modified surfaces is therefore almost impossible, making devices containing them (e.g.

Objective: To provide accurate data on health related behaviors and protective factors among students in middle schools in China, for developing priorities, programs and policies on health education.
Methods: We used a standard scientific sample selection process developed by American Center for Disease Control and Prevention (CDC) to conduct the questionnaire survey among middle schools from four cities--Beijing, Hangzhou, Wuhan and Urumchi.
Results: Data were found as: 3.
Immuno-PCR (IPCR) is a powerful detection technology in immunological study and clinical diagnosis due to its ultrasensitivity. Here we introduce a new strategy termed phage display mediated immuno-PCR (PD-IPCR). Instead of utilization of monoclonal antibody (mAb) and chemically bond DNA that required in the conventional IPCR, a recombinant phage particle is applied as a ready reagent for IPCR experiment.

Phage display technology was employed to generate scFv by using the protective antigen (PA) of B. anthracis for immunization.

Combining multiplex PCR with arrayed anchored primer PCR and biotin-avidin alkaline phosphatase indicator system, we developed a qualitative DNA chip method for characterization of B. anthracis, and simultaneous confirmation of the species identity independent of plasmid contents.
